Abstract:
This study developed a novel chair-side tongue pressure (TP) measuring instrument with a disposable positioning mouthpiece controlled using a smartphone application (APP), denoted as the TP wireless application (TPWA). The mouthpiece was designed with a palate-shaped air balloon containing a tongue contact bump and a plastic bite positioning tube. Fatigue load testing was performed to evaluate mouthpiece durability by applying 700 displacement cycles (50 times a day for one week during training, with twice the safety factor) on the air balloon. The main component used in developing this instrument was a silicon pressure sensor equipped with wireless Bluetooth connection. Young (52 adults; mean age = 20.23 ± 2.17) and elderly (40 adults; mean age = 72.60 ± 7.03) individuals participated in the test with the new instrument, with the results compared to those of a commercial device. The TPWA mouthpiece fatigue test showed that mean response pressures were maintained at 12 kPa. No significant (p > 0.05) differences were found during testing repetitions 0–10 and 701–710. There were no significant differences in the maximum TP values presented between the test sequences using different instruments for young and elderly participants. The TPWA results showed that TP values gradually decreased with increasing age (40.77 kPa for young and 16.55 kPa for elderly participants). The maximum TP for males (43.51 kPa) was significantly larger than that for females (35.14 kPa) in the young group, but an opposite trend was seen in the elderly group (12.97 for males and 17.59 for females). Thus, this study developed a novel chair-side TP measurement instrument with Bluetooth wireless mobile application control. A durable positioning oral mouthpiece was approved for measuring pressure sufficiently, reliably, and precisely for TP screening.

Abstract:
Breathing pattern and steady-state CO2 ventilatory response during mouth breathing were compared with those during nose breathing in nine healthy adults. In addition, the effect of warming and humidification of the inspired air on the ventilatory response was observed during breathing through a mouthpiece. We found the following. 1) Dead space and airway resistance were significantly greater during nose than during mouth breathing. 2) The slope of CO2 ventilatory responses did not differ appreciably during the two types of breathing, but CO2 occlusion pressure response was significantly enhanced during nose breathing. 3) Inhalation of warm and humid air through a mouthpiece significantly depressed CO2 ventilation and occlusion pressure responses. These results fit our observation that end-tidal PCO2 was significantly higher during nose than during mouth breathing. It is suggested that a loss of nasal functions, such as during nasal obstruction, may result in lowering of CO2, fostering apneic spells during sleep.

Abstract:
To investigate whether it is possible to simplify the methodology of measuring airway area by acoustic reflections, we measured upper airway area in 10 healthy subjects during tidal breathing according to seven different protocols. Three protocols employed custom-made bulky mouthpiece with or without nose-clips, two protocols used a scuba-diving mouthpiece and cotton balls placed in the nostrils instead of noseclips, and two protocols employed neck flexion and extension. We found no significant difference in average pharyngeal, glottic, and tracheal areas for any of the protocols except for neck flexion, which was associated with a significantly lower mean pharyngeal area. Intraindividual variabilities were comparable for all protocols, except for protocol employing the customary bulky mouthpiece and no noseclips, which consistently resulted in the most variable measurements of area for all three airway segments: pharynx, glottis, and trachea. Furthermore, we found that the protocol employing the scuba-diving mouthpiece with or without cotton balls in the nostrils resulted in the lowest number of unacceptable measurements. We conclude that measurements of airway area by acoustic reflections may be further simplified by using a scuba-diving mouthpiece without noseclips; furthermore, control of head position during measurements is not critical provided there is no obvious neck flexion.

Abstract:
Background: In this study, we focused on the habits of wind instrumentalists as well as the presence of playing instruments, and investigated associations between the risk of temporomandibular disorders (TMD) and playing wind instruments in non-professional musicians. Material and Methods: Seventy-two non-professional players of wind instruments (instrument group) (mean(SD), 20.0(1.1) y; 42 women) and 66 non-players (control group) (22.0(2.6) y; 45 women) participated in this study. Factors were investigated using questionnaires (a screening questionnaire for TMD, instrument playing habits, years of experience, and time played per day). Result: The prevalence of a high risk of TMD was not significantly different between the instrument group (29.2%) and control group (21.2%). In the instrument group, the frequency of subjects who felt mouthpiece pressure in the high risk of TMD group (47.6%) was significantly greater than that in the low risk of TMD group (21.6%). Mouthpiece pressure was found to be a significant factor contributing to a high risk of TMD (odds ratio, 3.31; 95% CI, 1.12–9.79). Conclusion: This study suggests that pressure from the mouthpiece was one of the contributing factors related to a high risk of TMD in non-professional wind instrument players.

Abstract:
Bernard Shaw (1856-1950) is one of the world famous playwrights, is a household wordsmith for his good humor and satire. In his masterpiece Mrs. Warren's Profession, Shaw depicts a literary figure Vivie who embodies new women's yearning for their independence and aspirations of self-values. This paper analyzes Vivie's image through approaches of narrative theory. By using narrative voice reflected in the scene, involvement of implied author in portrayal description, application of feminism in narratology, and dualistic construction in subtext, readers can have a more profound understanding of Vivie's image. Instead of a mouthpiece of "new women", the nature of Vivie's image is just sketched out on the basis of an ideal man under the male-dominated capitalist society. This paper concludes that in the capitalist society women were under the control of patriarchal discourse.

Abstract:
In the preceding companion paper (L. S. G. E. Howard and P.A. Robbins, J. Appl. Physiol. 78: 1092–1097, 1995), we showed that ventilation rises during 8 h of isocapnic hypoxia. In the present study we report the changes that occur in the ventilatory response to acute hypoxia (AHVR) over 8 h of both isocapnic and poikilocapnic hypoxia. Ten subjects completed the study. Each was seated inside a chamber in which the inspired gas could be controlled so as to maintain the desired end-tidal gases (sampled via nasal catheter) constant. Three 8-h protocols were compared: 1) isocapnic hypoxia, at an end-tidal PO2 of 55 Torr with the end-tidal PCO2 held at the subject's resting value; 2) poikilocapnic hypoxia, at the same end-tidal PO2; and 3) control, where the inspired gas was air. AHVR was measured before and at 20 min and 4 and 8 h after the start of the experiment. A sequence of hypoxic square waves and sawtooth inputs was imposed by an end-tidal forcing system, with the subject breathing through a mouthpiece. End-tidal PCO2 was held constant at 1–1.5 Torr above resting. Values for hypoxic sensitivity (Gp; 1.min-1.%-1) and hypoxia-independent ventilation (Vc; l/min) were calculated for each test of AHVR. Both Gp and Vc increased significantly during both hypoxic exposures in relation to control (P < 0.001, analysis of variance). Over the 8-h period, increases in Gp were 87% in isocapnic hypoxia and 44% in poikilocapnic hypoxia, and increases in Vc were 89% in isocapnic hypoxia and 84% in poikilocapnic hypoxia. There were no significant differences between the isocapnic and poikilocapnic exposures. We conclude that Gp and Vc rise mainly as result of hypoxia per se and not the associated alkalosis.

Abstract:
This article discusses the augmentation of acoustic musical instruments, with a focus on trumpet augmentation. Augmented instruments are acoustic instruments onto which sensors have been mounted in order to provide extra sonic control variables. Trumpets make ideal candidates for augmentation because they have spare physical space on which to mount electronics and spare performer “bandwidth” with which to interact with the augmentations. In this article, underlying concepts of augmented instrument design are discussed along with a review and discussion of twelve existing augmented trumpets and five projects related to mouthpiece augmentation. Common aspects to many of these examples are identified, such as the prevalence of idiosyncratic designs, the use of buttons placed at or near the left-hand playing position, and the focus on measuring or mimicking trumpet valves. Three existing approaches to valve sensing are compared, and a novel method for sensing valve position, based on linear variable differential transformers, is introduced. Based on the review and comparison, we created an example augmented trumpet that tests the feasibility of a modular design paradigm. The results of this review of the state-of-the-art and our own research suggests future directions towards a better understanding of augmented trumpet design.

Journal of Applied Physiology 126, no. 1 (January 1, 2019): 132–40. http://dx.doi.org/10.1152/japplphysiol.00841.2018.

Abstract:
Briefly occluding the airway during inspiration produces a short-latency reflex inhibition in human inspiratory muscles. This occlusion reflex seems specific to respiratory muscles; however, it is not known whether the reflex inhibition has a uniform effect across a motoneuron pool when a muscle is recruited concurrently for breathing and posture. In this study, participants were seated and breathed through a mouthpiece that occluded inspiratory airflow for 250 ms at a volume threshold of 0.2 liters. The reflex response was measured in the scalene and sternocleidomastoid muscles during 1) a control condition with the head supported in space and the muscles recruited for breathing only, 2) a postural condition with the head unsupported and the neck flexors recruited for both breathing and to maintain head posture, and 3) a large-breath condition with the head supported and the volume threshold raised to between 0.8 and 1.0 liters to increase inspiratory muscle activity. When normalized to its preocclusion mean, the reflex response in the scalene muscles was not significantly different between the large-breath and control conditions, whereas concomitant recruitment of these muscles for posture control reduced the reflex response by half compared with the control condition. A reflex response occurred in sternocleidomastoid when it contracted phasically as an accessory muscle for inspiration during the large-breath condition. These results indicate that the occlusion reflex does not produce a uniform effect across the motoneuron pool and that afferent inputs for this reflex most likely act via intersegmental networks of premotoneurons rather than at a motoneuronal level. NEW & NOTEWORTHY In this study, we investigated the effect of nonrespiratory activity on the reflex response to brief sudden airway occlusions in human inspiratory muscles. We show that the reflex inhibition in the scalene muscles was not uniform across the motoneuron pool when the muscle was recruited concurrently for breathing and postural control. The reflex had a larger effect on respiratory-driven motoneurons than those recruited to maintain head posture.

Abstract:
OBJECTIVE: Embouchure dystonia (EmD) is a variant of focal task-specific dystonia in musicians characterized by the loss of control in facial and oral muscles while controlling airflow into the mouthpiece of a wind or brass instrument. We compared tongue position variability (TPV) during sustained notes between healthy, elite horn players and horn players affected by EmD. METHODS: Real-time MRI films at 33.3 ms resolution were obtained from 8 healthy elite and 5 EmD horn players as they performed on a non-ferromagnetic horn at each of three different dynamic levels: pianissimo, mezzo forte, and fortissimo. Nine profile lines (3 from anterior, 3 from middle, and 3 from posterior oral cavity regions) were overlaid on each image using a customized MATLAB toolkit, and the variability of the dorsal tongue edge position was examined at each dynamic from temporal intensity profiles produced by MATLAB. RESULTS: Despite trends for more pronounced TPV (larger standard deviations) in the elite musicians (p=0.062), 2-way repeated measures ANOVA revealed no significant differences between groups. However, dynamic level significantly influenced TPV for all subjects, combined (p=0.048) and different regions of the oral cavity showed differing TPV (p<0.001). When only the most active region (anterior oral cavity) was included in the model, differences between groups reached statistical significance (elite > EmD, p<0.048), particularly at the fortissimo dynamic. We postulate that these differences may be due, in part, to a greater degree of generalized orofacial muscle tension in the EmD subjects that includes the tongue.

Abstract:
Air hunger is an unpleasant urge to breathe and a distressing respiratory symptom of cardiopulmonary patients. An increase in tidal volume relieves air hunger, possibly by increasing pulmonary stretch receptor cycle amplitude. The purpose of this study was to determine whether increasing end-expiratory volume (EEV) also relieves air hunger. Six healthy volunteers (3 women, 31 ± 4 yr old) were mechanically ventilated via a mouthpiece (12 breaths/min, constant end-tidal Pco2) at high minute ventilation (V̇e; 12 ± 2 l/min, control) and low V̇e (6 ± 1 l/min, air hunger). EEV was raised to ∼150, 400, 725, and 1,000 ml by increasing positive end-expiratory pressure (PEEP) to 2, 4, 6, and 8 cmH2O, respectively, for 1 min during high and low V̇e. The protocol was repeated with the subjects in the seated and supine positions to test for the effect of shifting baseline EEV. Air hunger intensity was rated at the end of each breath on a visual analog scale. The increase in EEV was the same in the seated and supine positions; however, air hunger was reduced to a greater extent in the seated position (13, 30, 31, and 44% seated vs. 3, 9, 23, and 27% supine at 2, 4, 6, and 8 cmH2O PEEP, respectively, P < 0.05). Removing PEEP produced a slight increase in air hunger that was greater than pre-PEEP levels ( P < 0.05). Air hunger is relieved by increases in EEV and tidal volume (presumably via an increase in mean pulmonary stretch receptor activity and cycle amplitude, respectively).

Abstract:
The article shows that outside ownership of media moves in stages – from media properties as the mouthpiece for personal and business interests, to a second stage of conglomerates seeking economic “synergies” of performance, to a third stage dominated by financial portfolio diversification. These phases of outside media ownership correspond to the stages of economic development in that country.The article finds that in rich countries, the ownership of media by industrial companies as a way to create political influence has been declining. The second phase, based on economic synergies, has become a less significant driver, too. On the other hand, there has been a significant growth of cross-ownership through financial intermediaries. In contrast, the media systems of emerging and developing countries are still operating in the first two phases of cross-ownership, centered on projection of influence and on conglomerate business synergies.It is quite likely that these dynamics will lead to a “capture gap” between emerging and rich societies. Media in the former would be significantly more captured through the seekers of personal influence and conglomerate synergies, while media in the latter are subject to professional investors imperatives of profitability, growth, predictability, and fit into portfolio diversification. The same financial institutions from rich countries are also likely to seek acquisitions in the emerging markets by leapfrogging the two other stages. The likely responses are restrictions on foreign ownership of media. Domestic conglomerates will step in and assume control. Media capture will then become patriotic.The article is fact-based and provides details on the media assets of non-media companies in 26 countries accounting for about 60% of the world’s population and over 80% of its economy.

Abstract:
PURPOSE: This study was intended to determine the effect of skin cooling on breath-hold duration and predicted emergency air supply duration during immersion.METHODS: While wearing a helicopter transport suit with a dive mask, 12 subjects (29 ± 10 yr, 78 ± 14 kg, 177 ± 7 cm, 2 women) were studied in 8 and 20°C water. Subjects performed a maximum breath-hold, then breathed for 90 s (through a mouthpiece connected to room air) in five skin-exposure conditions. The first trial was out of water for Control (suit zipped, hood on, mask off). Four submersion conditions included exposure of the: Partial Face (hood and mask on); Face (hood on, mask off); Head (hood and mask off); and Whole Body (suit unzipped, hood and mask off).RESULTS: Decreasing temperature and increasing skin exposure reduced breath-hold time (to as low as 10 ± 4 s), generally increased minute ventilation (up to 40 ± 15 L · min−1), and decreased predicted endurance time (PET) of a 55-L helicopter underwater emergency breathing apparatus. In 8°C water, PET decreased from 2 min 39 s (Partial Face) to 1 min 11 s (Whole Body).CONCLUSION: The most significant factor increasing breath-hold and predicted survival time was zipping up the suit. Face masks and suit hoods increased thermal comfort. Therefore, wearing the suits zipped with hoods on and, if possible, donning the dive mask prior to crashing, may increase survivability. The results have important applications for the education and preparation of helicopter occupants. Thermal protective suits and dive masks should be provided.Madu VC, Carnahan H, Brown R, Ennis K-A, Tymko KS, Hurrie DMG, McDonald GK, Cornish SM, Giesbrecht GG.

ABSTRACT IMPACT: Human exhaled breath is rich in metabolomic content that represents pulmonary function and gas exchange with blood, which can provide insights into an individual’s state of health. OBJECTIVES/GOALS: Human exhaled breath is rich in metabolomic content that represents pulmonary function and gas exchange with blood. It contains a mixture of compounds that offer insight into an individual’s state of health. Here, we present two novel non-invasive breath sampling devices for use in basic medical practice. METHODS/STUDY POPULATION: The two breath samplers have a disposable mouthpiece, a set of inhale and exhale one-way flap valves to allow condensation of exhaled breath only, and a saliva filter. The housing is constructed out of Teflon®, a chemically inert material to reduce chemical absorbance. The first device condenses exhaled breath into a frozen condensate using dry ice pellets and the other is a miniaturized design that liquifies exhaled breath on a condenser surface with micropatterned features on a cooling plate. Both designs have individual strategic and analytical advantages: frozen exhaled breath condensate (EBC) has high retention of analytes and sample volume; EBC collected in liquid phase offers facilitated sample collection and device portability. RESULTS/ANTICIPATED RESULTS: We investigated if breath aerosol size distribution affects the types or abundances of metabolites. We modified the geometry of the first device to redirect aerosol trajectories based on size. The trapping of larger aerosols increases with filter length, thus altering the aerosol size distribution although no significant changes in the metabolite profiles were found. With the miniaturized device, metabolite abundances were measured in a small cohort of healthy control and mild asthmatic subjects. Differences among subjects were found, as well as main differences between control and asthmatic groups. All analyses of EBC were performed with liquid chromatography - mass spectrometry. Inflammatory suppression found in asthmatic subjects can be explained by prescribed daily use of inhaled corticosteroids. DISCUSSION/SIGNIFICANCE OF FINDINGS: Breath collection devices can be used in intensive care units, outpatient clinics, workplaces, and at home. EBC analysis has been used to monitor asthma and chronic obstructive pulmonary disease. It can be applied to infectious respiratory diseases (e.g. influenza, COVID-19) and for monitoring environmental and occupational chemical exposures.

Abstract:
The role of the pulmonary function (PF) laboratory and PF testing equipment in the transmission of infections has not been established. Although microorganisms have been cultured from parts of in-use pulmonary function testing equipment, a relationship between equipment contamination and transmission of infection or colonization has not been documented. Nosocomial outbreaks of respiratory infections, eg, influenza, tuberculosis, and legionellosis have been described, but transmission of the microorganisms has not been shown to be more likely in the PF laboratory or with PF testing equipment than in other areas in the hospital or with other hospital equipment. Unlike nebulizers, which have been implicated in epidemic and endemic nosocomial gram-negative bacterial infections, PF machines do not generate aerosols. PF testing equipment is thus built without provision for easy machine disassembly and disinfection, except for parts that routinely come in contact with mucous membranes or secretions (eg, mouthpieces, valves, and some tubings).

Abstract:
Changes in intraocular pressure (IOP) elicited by a Valsalva manoeuvre were studied in 11 male patients (mean age 39.8 years) suffering from episodic cluster headache (CH), and 12 healthy male controls (mean age 39.9 years). The tests were performed at rest and while exhaling hard through a mouthpiece connected to a mercury manometer. In the CH group, during symptomatic periods, between attacks, Valsalva manoeuvre elicited an asymmetric increase in IOP with significantly higher values on the symptomatic side ( P = 0011), whereas no asymmetric increments in IOP were found during asymptomatic periods. Outside the cluster period the IOP values both baseline and with Valsalva manoeuvre did not differ from controls. The increment in IOP took place within a few seconds, as in spontaneous CH attacks, thus pointing to a rapid increase in intraocular blood volume or vasodilatation. These findings may reflect a latent increased vascular reactivity of the symptomatic orbit during CH period.

Abstract:
The article seeks to explore the common ground between biopolitics, fashion, patriotism and nostalgia. Taking off from the Foucauldian notion of biopolitics as a control apparatus exerted over a population, I provide an insight into the modern construction of the Russian nation, where personal and collective sacrifice, traditional femininity and masculinity, orthodox religion, and the Great Patriotic War become the basis for patriotism. On carefully chosen case studies, I will show how the state directly and indirectly regulates people's lives by producing narratives, which are translated (in some cases designers act as mouthpieces for the state demographic or military politics) into fashionable discourses and, with a core of time, create specific gender norms – women are seen as fertile mothers giving birth to new soldiers, while men are shown as fighters and defenders of their nation. In the constructed discourses, conservative ideals become a ground for the creation of an idea of a nation as one biological body, where brothers and sisters are united together. In these fashionable narratives, people's bodies become a battlefield of domestic politics. Fashion produces a narrative of a healthy nation to ensure the healthy work- and military force.

Abstract:
AbstractMaintaining oral function in older individuals with missing teeth is important for leading a healthy and independent life. This study aimed to evaluate whether simple isometric exercises can maintain and improve the oral function [maximum occlusal force (MOF) and masticatory ability (MA)] and the masticatory muscle properties [masseter muscle thickness (MMT) and echo intensity (MMEI)] in older adults during the maintenance phase of removable prosthetic treatment. Participants were randomly categorized into the intervention and control groups. The mouthpieces were distributed, and participants were instructed to use them for exercising. The intervention group was instructed to perform maximum clenching for 10 s, whereas the control group was instructed to tap the teeth at an arbitrary speed for 10 s. Both were repeated five times at an interval of 5 s between each activity and twice daily for 4 weeks. The outcomes were measured after a month of exercise. The intervention group showed a significant improvement in the MOF, MMT during contraction, MMT at rest and MMEI during contraction. There were no significant differences in the MA and MMEI at rest. In the control group, no improvement was observed in any of the parameters. When the isometric exercises were performed using a mouthpiece, there was an improvement in the oral function and masseter muscle properties in older individuals with Eichner B status who used dentures.

Abstract:
In 2018, the Medical Panel of the NATO Underwater Diving Working Group (UDWG) discussed the question of the rescue and management of a submerged unresponsive compressed-gas diver. The Panel reviewed the 2012 recommendation by the UHMS Diving Committee with respect to the specific recommendation in a convulsing diver using a half-face mask and separate mouthpiece, to delay surfacing until the clonic phase had subsided if the mouthpiece was in place. There is a paucity of scientific, epidemiological, experimental and observational human studies to substantiate this guidance. Experimental animal studies suggest that the likelihood of a complete airway obstruction during an ongoing seizure is low and that there is a high likelihood of surviving pulmonary barotrauma caused by complete airway closure. Airway management and control is an essential step in the management of the unresponsive diver and would be challenging to achieve in the underwater environment. Even in the military setting, it will be difficult to provide sufficient training to enable divers to handle such a situation. In this very rare scenario it is considered that emergency guidelines should be clear, concise and easy to follow. The UDWG therefore recommends that all unconscious military divers in this situation should be rescued to surface without waiting for clonic seizures to subside. Training organizations for recreational and occupational divers should consider whether this guidance should be applied for civilian divers as well.

Abstract:
Background: The six-minute walk test (6MWT) is widely used because it is both simple and reliable as a measure of exercise capacity. Individuals with chronic obstructive pulmonary disease (COPD) usually show a limited capacity to perform exercise. Methods: Our study is a prospective, randomized controlled trial which uses the 6MWT in one hundred consecutive in and out- patients with moderate to severe COPD to assess the benefit of a simple positive expiratory pressure (PEP) device. PEP device consisted of a PEP valve 5 cmH2O connected to 1-meter tube and a mouthpiece. All the enrolled patients performed a 6MWT before randomization. The following day PEP group patients performed the 6MWT using PEP device. Control group patients performed the 6MWT without this device. The primary outcome was the difference in distance (meters) walked. Results: Functional capacity assessed by the distance covered during 6MWT improved in the PEP group more than in the control group. The difference was statistically significant (p < 0.001).Oxygen saturation improved to a statistically significant level during 6MWT (p < 0.01). Heart rate was also reduced (p < 0.03). Conclusions: There are few studies demonstrating that PEP devices enhance exercise capacity in COPD patients. Our results has been obtained using only a low positive expiratory pressure (5 cmH2O). In our opinion the strength of this study is the simplicity and the lower cost when compared to other devices and approaches. The study was registered as Chi CTR-ORC-12002173 at www.chictr.org.

Abstract:
Objective: We recently reported that a global-level metabolic alteration occurs after cardiac arrest (CA) in our high fidelity rodent model. The finding was that dissociation of O 2 consumption (VO 2 ) and carbon dioxide generation (VCO 2 ) resulted in a respiratory quotient (RQ: calculated by dividing VCO 2 by VO 2 ) that fell well outside the normally cited range of 0.7-1.0. We hypothesized that a lowered RQ is similarly found in human CA patients. Methods: The study consisted of three subject groups: 1) healthy volunteer, 2) post-surgical patient (control) and 3) post-CA patient. We measured the VO 2 and VCO 2 of mechanically ventilated subjects using the Douglas bag method. Inspiration and expiration gas samples were collected in two separate bags . and RQ was calculated from CO 2 and O 2 gas concentrations in the samples. The patients and healthy volunteers were ventilated using the same model mechanical ventilator. Alert healthy volunteers bit onto a mouthpiece and the samples were collected, while post-surgical and post-CA patients were unconscious during the measurements. We measured the RQ of healthy volunteers at normal and high fractions of inspired oxygen (FIO 2 ) in order to test the validity of our methods at various inspired O 2 levels. Results: The RQs of the three healthy volunteers were 0.83, 0.92 and 0.85 at an FIO 2 of 0.21 and 0.86, 0.88, and 0.83 at an FIO 2 of 0.90 respectively. The RQs of the two post-surgical patients were 0.92 and 0.88 at an FIO 2 of 0.5. None of the post-surgical patients had any complications following the surgery and all were discharged. The RQ of a post-CA patient measured 2.5 hours after the CA was found to be 0.72 at an FIO 2 of 0.9. The CA patient expired within 24 hours of hospital admission. Conclusions: The same trend between the findings of both our rodent study and the CA patient suggest that resuscitation from CA alters cellular metabolism on a global level. This metabolic alteration in turn causes the dissociation of O 2 consumption and CO 2 generation resulting in a lowered RQ. Our findings warrant a larger clinical study to confirm a lowered RQ in post-CA patients and bench work to elucidate the causative mechanism of this relationship.

Abstract:
The profession of newspaper has been becoming more challenging in recent years. In the underdeveloped country like Nepal, media has been misused, misguided and misbehaved. The big publishing house monopolized market. They have influenced in using government facilities and diverting people's attention towards their narrow interest of political nature. In fact, newspaper can play disaster role to destroy political and social system. In the time of people's movement, newspaper has played active role to initiate revolution. Negative news has been diffused much during the People's Movement. Everything good or bad has been criticized. Newspapers often used bombarding words to oppose opposition's role. Similarly, unsocial and inhuman activities have been encouraged by publishing random thoughts and prioritizing their news on attack and crimes. Publication of negative news ultimately hampered the journalist. Standardization of newspaper in the changing context can be achieved by promoting more creative works and encouraging those activities which have reformed the society and also contributed to bring sound development. The society never can go up just reading negative news and anti social news. The journalist needs to reform their vision. They should focus good, encouraging and creative news rather than publishing critical news on harassment to personalities and cool events. Weekly newspaper are playing active role as mouthpiece of their parties and/or school of thoughts. They are neglecting people's aspiration and highlighting one sided thoughts without considering other's ideas and visions. This brought high toll in vandalism in media. Crime is increasing. The value system has been collapsed. People discouraged and country headed towards failure state. Newspaper should work as a watching dog to protect human values, national sovereignty, national unity and identity. Creativity and constructive ideas must be promoted. Narrow and selfish individual never can be a successful journalist. A journalist is also a lawyer and referee. Journalist can play a role of parents to the nation. Freedom for the enrichment of human civilization must be considered. A journalist has great role but never can be a dictator. Journalist is a mediator not ruler. Journalist can make the king not treat himself as a king. Journalist is freedom fighter but restricted to use own freedom. Social norms and values, academic conscience and humanistic attitude control them. To promote society, journalist should encourage literature, music and art. Without enriching them, man becomes beast. To promote development, journalist has to cooperate to disseminate new creative and constructive ideas. Too much criticism is fatal. It may boomerang. Critical thinking is essential but it should be for the betterment of situation not to bring worst condition in the life of the people and country. In my observation, maturity is lacking in the contemporary Nepali newspaper. The situation will improve soon because young journalist is emerging and they are in learning process. Their learning certainly will teach to guide the betterment of the society and bring fruitful development in the nation.

Abstract:
Abstract Introduction In order to play a wind instrument one must have a good breathing control with rhythm variation, control of inspiratory and expiratory volume as well as a good control of the airflow transmitted by the musician through the different mouthpieces. The pulmonary function of the different wind instrument players has been scarcely studied generating divergent conclusions. Objectives To characterize and compare lung function and functional capacity of musicians of different wind instruments. Methodology One hundred and one individuals from five philharmonic bands from Aveiro and Porto districts were studied. Smokers or ex-smokers for less than one year, respiratory pathology, history of chronic pulmonary or cardiac disease were exclusion criteria. The sample was divided into three groups: "Air reed", "Reeds" and "Metals". Pulmonary function was assessed by spirometry: forced vital capacity (FVC), forced expiratory volume in first second (FEV1), Tiffeneau index (TI), peak expiratory flow (PEF) and maximal voluntary ventilation (MVV). Functional capacity was assessed using the six-minute walk test (6-MWT). Data analysis was performed in the Statistical Package for the Social Sciences with a 95% confidence interval. Chi-square test, Mann-Whitney U test, ANOVA test and Kruskal-Wallis test were used. Results All spirometric parameters with the exception of TI were increased in "Metals" group with significant decrease in the "Air reed" parameters of FEV1 (p = 0.045) and MVV (p = 0.004). A negative correlation between FEV1 and 6-MWT was noticed in male musicians (r=-0.291; p = 0.022). Conclusion Musicians from the “Metals” group showed better lung function when compared to other groups. There was no positive correlation between lung function and functional capacity of the studied musicians. However, there was a weak negative correlation between FEV1 of male musicians and their functional capacity.

Abstract:
Historically, science and medicine have been a great source of inspiration for fiction writers. Mary Shelley, in the 1831 introduction to her novel Frankenstein said she was been inspired, in part, by discussions about scientific experiments, including those of Darwin and Galvani. Shelley states “perhaps a corpse would be re-animated; galvanism had given token of such things: perhaps the component parts of a creature might be manufactured, brought together, and endued with vital warmth” (10). Countless other authors have followed her lead, from H.G. Wells, whose mad scientist Dr Moreau takes a lead from Shelley’s Dr Frankenstein, through to popular contemporary writers of adult fiction, such as Michael Crichton and Kathy Reichs, who have drawn on their scientific and medical backgrounds for their fictional works. Science and medicine themed fiction has also proven popular for younger readers, particularly in dystopian settings. Reichs has extended her writing to include the young adult market with Virals, which combines forensic science with the supernatural. Alison Allen-Grey’s 2009 novel, Lifegame, deals with cloning and organ replacement. Nathan Hobby’s The Fur is based around an environmental disaster where an invasive fungal-fur grows everywhere, including in people’s internal organs. Catherine Jinks’ Piggy in the Middle incorporates genetics and biomedical research into its horror-science fiction plot. Brian Caswell’s young adult novel, Cage of Butterflies uses elements of neuroscience as a plot device. However, although Caswell’s novel found commercial and critical success—it was shortlisted in the 1993 Children’s Book Council of Australia (CBCA) Book of the Year Awards Older Readers and was reprinted several times—neuroscience is a field that writers of young adult fiction tend to either ignore or only refer to on the periphery. This paper will explore how neuroscientific and dystopian elements interact in young adult fiction, focusing on the current trend for neuroscientific elements to be something that adolescent characters are subjected to rather than something they can use as a tool of positive change. It will argue that the time is right for a shift in young adult fiction away from a dystopian world view to one where the teenaged characters can become powerful agents of change. The term “neuroscience” was first coined in the 1960s as a way to hybridise a range of disciplines and sub-disciplines including biophsyics, biology and chemistry (Abi-Rached and Rose). Since then, neuroscience as a field has made huge leaps, particularly in the past two decades with discoveries about the development and growth of the adolescent brain; the dismissal of the nature versus nurture dichotomy; and the acceptance of brain plasticity. Although individual scientists had made discoveries relating to brain plasticity in adult humans as far back as the 1960s, for example, it is less than 10 years since neuroplasticity—the notion that nerve cells in human brains and nervous systems are malleable, and so can be changed or modified by input from the environment—was accepted into mainstream scientific thinking (Doidge). This was a significant change in brain science from the once dominant principle of localisation, which posited that specific brain functions were fixed in a specific area of the brain, and that once damaged, the function associated with a brain area could not improve or recover (Burrell; Kolb and Whishaw; Doidge). Furthermore, up until the late 1990s when neuroscientist Jay Giedd’s studies of adolescent brains showed that the brain’s grey matter, which thickens during childhood, thins during adolescence while the white matter thickens, it was widely accepted the human brain stopped maturing at around the age of twelve (Wallis and Dell). The research of Giedd and others showed that massive changes, including those affecting decision-making abilities, impulse control and skill development, take place in the developing adolescent brain (Carr-Gregg). Thus, within the last fifteen years, two significant discoveries within neuroscience—brain plasticity and the maturation of the adolescent brain­—have had a major impact on the way the brain is viewed and studied. Brian Caswell’s Cage of Butterflies, was published too early to take advantage of these neuroscientific discoveries. Nevertheless the novel includes some specific details about how the brains of a group of children within the story, the Babies, have been altered by febrile convulsions to create an abnormality in their brain anatomy. The abnormality is discovered by a CAT scan (the novel predates the use of fMRI brain scans). Due to their abnormal brain anatomy, the Babies are unable to communicate verbally but can communicate telepathically as a “shared mind” with others outside their small group. It is unlikely Caswell would have been aware of brain plasticity in the early 1990s, nevertheless, in the narrative, older teens are able to slowly understand the Babies by focusing on their telepathic messages until, over time, they can understand them without too much difficulty. Thus Caswell has incorporated neuroscientific elements throughout the plot of his novel and provided some neuroscientific explanation for how the Babies communicate. In recent years, several young adult novels, both speculative and contemporary, have used elements of neuroscience in their narratives; however, these novels tend to put neuroscience on the periphery. Rather than embracing neuroscience as a tool adolescent characters can use for their benefit, as Caswell did, neuroscience is typically something that exists around or is done to the characters; it is an element over which they have no control. These novels are found across several sub-genres of young adult fiction, including science fiction, speculative fiction and contemporary fiction. Most place their narratives in a dystopian world view. The dystopian settings reinforce the idea that the world is a dangerous place to live, and the teenaged characters living in the world of the novels are at the mercy of powerful oppressors. This creates tension within the narrative as the adolescents battle authorities for power. Without the ability to use neuroscientific advantages for their own gain, however, the characters’ power to change their worlds remains in the hands of adult authorities and the teenaged characters ultimately lose the fight to change their world. This lack of agency is evident in several dystopian young adult novels published in recent years, including the Uglies series and to a lesser extent Brain Jack and Dark Angel. Scott Westerfeld’s Uglies series is set in a dystopian future world and uses neuroscientific concepts to both reinforce the power of the ruling regime and give limited agency to the protagonists. In the first book in the series, Uglies, the science supports the narrative where necessary but is always subservient to the action. Westerfeld’s intended the Uglies series to focus on action. Westerfield states “I love a good action sequence, and this series is of full of hoverboard chases, escapes through ancient ruins, and leaps off tall buildings in bungee jackets” (Books). Nevertheless, the brain’s ability to rewire itself—the neuroscientific concept of brain plasticity—is a central idea within the Uglies series. In book one, the protagonist Tally Youngblood is desperate to turn 16 so she can join her friends and become a Pretty. However, she discovers the operation to become a Pretty involves not just plastic surgery to alter her looks: a lesion is inflicted on the brain, giving each Pretty the equivalent of a frontal lobotomy. In the next book, Pretties, Tally has undergone the procedure and then becomes one of the elite Specials, and in the third instalment she eventually rejects her Special status and returns to her true nature. This latter process, one of the characters explains, is possible because Tally has learnt to rewire her brain, and so undo the Pretty operation and the procedure that made her a Special. Thus neuroscientific concepts of brain injury and recovery through brain plasticity are prime plot devices. But the narrative offers no explanations for how Tally and some others have the ability to rewire their brains to undo the Pretty operation while most do not. The apparent complexity of the neuroscience is used as a surface plot device rather than as an element that could be explored to add narrative depth. In contrast, the philosophical implications of recent neuroscientific discoveries, rather than the physical, are explored in another recent young adult novel, Dark Angel. David Klass’ novel, Dark Angel, places recent developments in neuroscience in a contemporary setting to explore the nature of good and evil. It tells the story of 17-year-old Jeff, whose ordinary, small-town life implodes when his older brother, Troy, comes home on parole after serving five years for manslaughter. A school assignment forces Jeff to confront Troy’s complex nature. The science teacher asks his class “where does our growing knowledge of the chemical nature of the brain leave us in terms of... the human soul? When we think, are we really making choices or just following chemical pathways?” (Klass 74). This passage introduces a neuroscientific angle into the plot, and may refer to a case brought before the US Supreme Court in 2005 where the court admitted a brief based on brain scans showing that adolescent brains work differently than adult brains (Madrigal). The protagonist, Jeff, explores the nature of good and evil through this neuroscientific framework as the story's action unfolds, and examines his relationship with Troy, who is described in all his creepiness and vulnerability. Again through the teacher, Klass incorporates trauma and its impact on the brain from a neuroscientific perspective: There are psychiatrists and neurologists doing studies on violent lawbreakers...who are finding that these felons share amazingly similar patterns of abusive childhoods, brain injuries, and psychotic symptoms. (Klass 115)Jeff's story is infused with the fallout of his brother’s violent past and present, yet there is no hint of any trauma in Jeff’s or Troy’s childhoods that could be seen as a cause for Troy’s aberrant behaviour. Thus, although Klass’ novel explores more philosophical aspects of neuroscience, like Westerfeld’s novel, it uses developments in neuroscience as a point of interest. The neuroscience in Dark Angel is not embedded in the story but is a lens through which to view the theme of whether people are born evil or made evil. Brain Jack and Being are another two recent young adult novels that explore physical and philosophical aspects of modern neuroscience to some extent. Technology and its possible neurological effects on the brain, particularly the adolescent brain, is a field of research popularised by English neuroscientist Baroness Susan Greenfield. Brian Falkner’s 2010 release, Brain Jack, explores this branch of neuroscience with its cautionary tale of a hands-free device—a cap with small wires that attach to your head called the neuro-headset­—that allows you to control your computer with your thoughts. As more and more people use the neuro-headset, the avatar designed to help people learn to use the software develops consciousness and its own moral code, destroying anyone who it considers a threat by frying their brains. Like Dark Angel and Uglies, Brain Jack keeps the neuroscience on the periphery as an element over which the characters have little or no control, and details about how the neuro-headset affects the brain of its wearers, and how the avatar develops consciousness, are not explored. Conversely, Kevin Brooks’ novel Being explores the nature of consciousness outside the field of neuroscience. The protagonist, Robert, goes into hospital for a routine procedure and discovers that instead of internal organs, he has some kind of hardware. On the run from authorities who are after him for reasons he does not understand, Robert tries frantically to reconstruct his earliest memories to give him some clue as to who, or what, he really is: if he does not have normal human body parts, is he human? However, whether or not he has a human brain, and the implications of either answer for his consciousness, is never addressed. Thus, although the novels discussed above each incorporate neuroscience to some degree, they do so at a cursory level. In the case of Being this is understandable as neuroscience is never explicitly mentioned; rather it is a possible sub-text implied through the theme of consciousness. In Dark Angel, through the teacher as mouthpiece, neuroscience is offered up as a possible explanation for criminal behaviour, which causes the protagonist to question his beliefs and judgements about his brother. However, in Uglies, and to a lesser extent in Brain Jack, neuroscience is glossed over when more detail may have added extra depth and complexity to the novels. Fast-paced action is a common element in much contemporary young adult fiction, and thus it is possible that Westerfeld and Falkner both chose to sacrifice complexity for the sake of action. In Uglies, it is likely this is the case, given Westerfeld’s love of action sequences and his attention to detail about objects created exclusively for his futuristic world. However, Brain Jack goes into explicit detail about computer hacking. Falkner’s dismissal of the neuroscientific aspects of his plot, which could have added extra interest, most likely stems from his passion for computer science (he studied computer science at university) rather than a distaste for or ignorance of neuroscience. Nevertheless Falkner, Westerfeld, Brooks, and to a lesser extent Klass, have each glossed over a source of potential power that could turn the dystopian worlds of their novels into one where the teenaged protagonists hold the power to make lasting change. In each of these novels, neuroscientific concepts are generally used to support a bleak or dystopian world view. In Uglies, the characters have two choices: a life as a lobotomised Pretty or a life on the run from the authorities, where discovery and capture is a constant threat. The USA represented in Brain Jack descends into civil war, where those unknowingly enslaved by the avatar’s consciousness fight against those who refuse to wear the neuro-headsets. The protagonist in Being lives in hiding from the secret authorities who seek to capture and destroy him. Even in Dark Angel, the neuroscience is not a source of comfort or support for the protagonist, whose life, and that of his family, falls apart as a consequence of his older brother’s criminal actions. It is only in the 1990s novel, Cage of Butterflies, that characters use a neuroscientific advantage to improve their situation. The Babies in Caswell’s Cage of Butterflies are initially victims of their brain abnormality; however, with the help of the teenaged characters, along with two adult characters, they are able to use their “condition” to help create a new life for themselves. Telepathically communicating through their “shared mind,” the Babies coordinate their efforts with the others to escape from the research scientists who threaten their survival. In this way, what starts as a neurological disability is turned into an advantage. Cage of Butterflies illustrates how a young adult novel can incorporate neuroscience into its narrative in a way that offers the young adults agency to make positive changes in their lives. Furthermore, with recent neuroscientific discoveries showing that adolescence is a vital time for brain development and growth, there is potential for neuroscience to be explored as an agent of positive change in a new wave of young adult fiction, one that adopts a non-dystopian (if not optimistic) world view. Dystopian young adult fiction has been enjoying enormous popularity in western publishing in the past few years with series such as Chaos Walking, Hunger Games and Maze Runner trilogies topping bestseller lists. Dystopian fiction’s appeal to young adult audiences, states Westerfeld, is because: Teenagers’ lives are constantly defined by rules, and in response they construct their identities through necessary confrontations with authority, large and small. Imagining a world in which those authorities must be destroyed by any means necessary is one way of expanding that game. ("Teenage Wastelands")Teenagers often find themselves in trouble, and are almost as often like to cause trouble. Placing them in a fictional dystopian world gives them room to fight authority; too often, however, the young adult protagonists are never able to completely escape the world the adults impose upon them. For example, the epilogue of James Dashner’s The Maze Runner tells the reader the surviving group have not escaped the makers of the maze, and their apparent rescuers are part of the same group of adult authorities. Caswell’s neurologically evolved Babies, along with their high IQ teenage counterparts, however, provide a model for how young protagonists can take advantage of neuroscientific discoveries to cause trouble for hostile authorities in their fictional worlds. The power of the brain harnessed by adolescents, alongside their hormonal changes, is by its nature a recipe for trouble: it has the potential to give young people an agency and power adults may fear. In the everyday, lived world, neuroscientific tools are always in the hands of adults; however, there needs to be no such constraint in a fictional world. The superior ability of adolescents to grow the white matter of their brains, for example, could give rise to a range of fictional scenarios where the adolescents could use their brain power to brainwash adults in authority. A teenage neurosurgeon might not work well in a contemporary setting but could be credible in a speculative fiction setting. The number of possible scenarios is endless. More importantly, however, it offers a relatively unexplored avenue for teenaged characters to have agency and power in their fictional worlds. Westerfeld may be right in his assertion that the current popularity of dystopian fiction for young adults is a reaction to the highly monitored and controlled world in which they live ("Teenage Wastelands"). However, an alternative world view, one where the adolescents take control and defeat the adults, is just as valid. Such a scenario has been explored in Cory Doctorow’s For the Win, where marginalised and exploited gamers from Singapore and China band together with an American to form a global union and defeat their oppressors. Doctorow uses online gaming skills, a field of expertise where youth are considered superior to adults, to give his characters power over adults in their world. Similarly, the amazing changes that take place in the adolescent brain are a natural advantage that teenaged characters could utilise, particularly in speculative fiction, to gain power over adults. To imbue adolescent characters with such power has the potential to move young adult fiction beyond the confines of the dystopian novel and open new narrative pathways. The 2011 Bologna Children’s Book Fair supports the view that western-based publishing companies will be looking for more dystopian young adult fiction for the next year or two (Roback). However, within a few years, it is possible that the popularity of zombies, werewolves and vampires—and their dominance of fictional dystopian worlds—will pass or, at least change in their representations. The “next big thing” in young adult fiction could be neuroscience. Moreover, neuroscientific concepts could be incorporated into the standard zombie/vampire/werewolf trope to create yet another hybrid to explore: a zombie virus that mutates to give a new breed of undead creature superior intelligence, for example; or a new cross-breed of werewolf that gives humans the advantages of the canine brain with none of the disadvantages. The capacity and complexity of the human brain is enormous, and thus it offers enormous potential to create exciting young adult fiction that explores new territory, giving the teenaged reader a sense of their own power and natural advantages. In turn, this is bound to give them infinite potential to create fictional trouble.
