Streszczenie:

This study provides comprehensive details of evaporative cooling options for building air-conditioning (AC) in Multan (Pakistan). Standalone evaporative cooling and standalone vapor compression AC (VCAC) systems are commonly used in Pakistan. Therefore, seven AC system configurations comprising of direct evaporative cooling (DEC), indirect evaporative cooling (IEC), VCAC, and their possible combinations, are explored for the climatic conditions of Multan. The study aims to explore the optimum AC system configuration for the building AC from the viewpoints of cooling capacity, system performance, energy consumption, and CO2 emissions. A simulation model was designed in DesignBuilder and simulated using EnergyPlus in order to optimize the applicability of the proposed systems. The standalone VCAC and hybrid IEC-VCAC & IEC-DEC-VCAC system configurations could achieve the desired human thermal comfort. The standalone DEC resulted in a maximum COP of 4.5, whereas, it was 2.1 in case of the hybrid IEC-DEC-VCAC system. The hybrid IEC-DEC-VCAC system achieved maximum temperature gradient (21 °C) and relatively less CO2 emissions as compared to standalone VCAC. In addition, it provided maximum cooling capacity (184 kW for work input of 100 kW), which is 85% higher than the standalone DEC system. Furthermore, it achieved neutral to slightly cool human thermal comfort i.e., 0 to −1 predicted mean vote and 30% of predicted percentage dissatisfied. Thus, the study concludes the hybrid IEC-DEC-VCAC as an optimum configuration for building AC in Multan.

Pulmonary atresia with the intact ventricular septum (PA-IVS) is a rare anomaly that has an absent communication between the right ventricle and pulmonary arterial circulation. PA-IVS has a hypoplastic and hypokinetic and thickened right ventricle with the intact ventricular septum. It can be diagnosed with PA-IVS in routine obstetric ultrasound examination because the four-chamber view of PA-IVS is generally abnormal. The size of the right ventricular cavity is proportional to the Z value of the diameter of the tricuspid valve. The essential associated cardiac finding of PA-IVS is ventricular-coronary arterial communications (VCAC). The hypertensive RV forces blood through the intramyocardial sinusoids with continuous fistulous contact with the epicardial branches of RCA. It is called the VCAC. A color Doppler can detect VCAC due to its location in the pericardium along the coronary artery. If patients have VCAC and tricuspid Z score below -4, all of these conditions are infallible signs of high mortality rates in their fetal or postnatal lives. Our aim in presenting this case is to remind perinatologists if they detect an abnormal four-chamber view of the fetus’s heart, they should also carefully examine whether VCAC exists. Herein, we report a case of PA-IVS and VCAC at 21 weeks’ gestation with fetal echocardiographic images.

Analizar comparativamente los sistemas nacionales de vigilancia de la calidad del agua para consumo humano (VCACH) de Brasil y Colombia, con el fin de comprender como están organizadas las prácticas en estos países, sus límites y posibilidades.Métodos: Se utilizó la metodología Cross Nacional, mediante el análisis documental de fuentes secundarias, las cuales fueron obtenidas a través de las instituciones responsables y páginas oficiales. Con el propósito de discutir las convergencias y divergencias entre los dos sistemas, considerando las directrices de la Organización Mundial da Salud. Resultados: Los marcos legales de la VCACH en Brasil y Colombia comienzan a definirse en la década 70-80, coincidiendo con la visibilidad internacional de esta temática. Las prácticas de VCACH en el Brasil estuvieron definidas y organizadas en un programa nacional, lo que solamente se está dando en Colombia recientemente. Las actuales legislaciones avanzan en los componentes que orientan las prácticas de vigilancia, por ejemplo, incorporación de metodologías de evaluación de riesgo. La legislación colombiana establece la regulación de la prestación de los servicios de abastecimiento de agua, aspecto no contemplado en la legislación brasilera. Elementos como descentralización, intersectorialidad, universalidad y el derecho a información son contemplados en las legislaciones de ambos países, aunque las acciones de VCACH necesiten avanzar para la efectiva operatividad de los mismos. Conclusiones: Brasil y Colombia presentan semejanzas en los procesos de definición de la VCACH, estando en momentos distintos de implementación de las acciones de VCACH. Estas son necesarias para garantizar los derechos humanos relacionados con la preservación de ambiente, así como la universalidad del acceso a agua potable en cantidades y en calidad adecuadas, contribuyendo en la promoción de la salud.

Abstract This article studies Chinese V-de sentences from the perspective of verb-copying constructions (VCC) and presents some more evidence in favor of the distinction between descriptive V-de constructions and resultative V-de constructions. VCC with descriptive V-de sentences (VCCD) and VCC with resultative V-de sentences (VCCR) are linearly described as [NP1+ V1+ NP2 + V2 + de +XP]. Five asymmetries, though not very sharp, have been observed between VCCD and VCCR: (a) the movement asymmetry of [V1+NP2], (b) the questioning asymmetry between weishenme ‘why’ and shenme ‘what’, (c) the definiteness asymmetry of NP2, (d) the repetition asymmetry of V1, and (e) the asymmetry of subject-oriented adverb guyi ‘intentionally’. To explain these differences, we assume that [V1+NP2] in VCCD is a constituent, acting as an internal topic. While similar analysis cannot be extended to VCCR. We propose instead that [NP1+V1+NP2] is a constituent in VCCR, projecting further into a complex NP and acting as a sentential subject. These structural differences can well explain the five asymmetries from the island effects, and the semantic and pragmatic constraints (on internal topics and subject-oriented adverbs). Meanwhile, based on the restriction of manner adverbial modification, the V2 in VCCD and VCCR is assumed to be externally merged at the morphological level via External Morphological Merger to satisfy the affixal properties of de. The copying of V1 as V2 is not driven syntactically, but morphologically. This morphosyntactic approach to VCCD and VCCR provides a new perspective to explore V-de sentences and VCC, which may shed light on the morphosyntactic studies of Mandarin Chinese from a crosslinguistic perspective.

The purpose of this research is to prepare a predictive model for identifying credit crisis using an artificial neural network. The paper also aims to find out the driver and driven relationship between various financial instruments like CDS, FRA, IRS, and the Volatility index (VCAC) and government securities for France. The model, thus, is directed towards finding a threshold for credit pit events and linking various events corresponding to that dates where the threshold is breached to validate the accuracy and usefulness of the model. From the research, it is found that for France, the CDS-FRA-VCAC model derives the threshold for VCAC to indicate the probability of credit crisis or financial market crash. It is also found that sovereign bonds have a huge impact on France economy including various derivatives. This is probably why the Eurozone debt crisis impacted France much more than the 2008 financial crash.

Este estudio analiza la capacidad de 14 niños (35% varones) entre 2 y 3 años (M = 2.9; SD = 0.17) para comprender los deseos. La literatura ha dado por sentado que niños de esas edades comprenden deseos simples, amparándose en una postura estructuralista del desarrollo, en la que básicamente hay una descripción de hitos que están relacionados con la edad. En contraposición a esta tradición, este estudio busca dar cuenta del cambio y la variabilidad, apoyándose en la teoría de los Sistemas Dinámicos No Lineales. Por ello, usando el método microgenético, se evaluó durante varias sesiones la capacidad de los niños para usar los deseos de otros para predecir emociones y comportamientos. Se adaptaron las tareas clásicas de Wellman y Wooley (1990), y se les presentaron a los niños en 5 sesiones, en las que había 3 variaciones de las tareas. Los datos se analizaron con la técnica de mínimos y máximos, y se encontraron un conjunto de trayectorias con muchas fluctuaciones, que distan de mostrar desempeños altos y estables como lo afirman estudios previos. Se concluye que en la investigación sobre el desarrollo, las visiones acumulativas y homogéneas dificultan la observación del cambio y de la amplitud del mismo, por ello se requiere hacer hincapié en la variabilidad.

Streszczenie:

Quantitative and qualitative running gait analysis allows the early identification and the longitudinal monitoring of gait abnormalities linked to running-related injuries. A promising calibration- and marker-less video sensor-based technology (i.e., Graal), recently validated for walking gait, may also offer a time- and cost-efficient alternative to the gold-standard methods for running. This study aim was to ascertain the validity of an improved version of Graal for quantitative and qualitative analysis of running. In 33 healthy recreational runners (mean age 41 years), treadmill running at self-selected submaximal speed was simultaneously evaluated by a validated photosensor system (i.e., Optogait—the reference methodology) and by the video analysis of a posterior 30-fps video of the runner through the optimized version of Graal. Graal is video analysis software that provides a spectral analysis of the brightness over time for each pixel of the video, in order to identify its frequency contents. The two main frequencies of variation of the pixel’s brightness (i.e., F1 and F2) correspond to the two most important frequencies of gait (i.e., stride frequency and cadence). The Optogait system recorded step length, cadence, and its variability (vCAD, a traditional index of gait quality). Graal provided a direct measurement of F2 (reflecting cadence), an indirect measure of step length, and two indexes of global gait quality (harmony and synchrony index). The correspondence between quantitative indexes (Cadence vs. F2 and step length vs. Graal step length) was tested via paired t-test, correlations, and Bland–Altman plots. The relationship between qualitative indexes (vCAD vs. Harmony and Synchrony Index) was investigated by correlation analysis. Cadence and step length were, respectively, not significantly different from and highly correlated with F2 (1.41 Hz ± 0.09 Hz vs. 1.42 Hz ± 0.08 Hz, p = 0.25, r2 = 0.81) and Graal step length (104.70 cm ± 013.27 cm vs. 107.56 cm ± 13.67 cm, p = 0.55, r2 = 0.98). Bland–Altman tests confirmed a non-significant bias and small imprecision between methods for both parameters. The vCAD was 1.84% ± 0.66%, and it was significantly correlated with neither the Harmony nor the Synchrony Index (0.21 ± 0.03, p = 0.92, r2 = 0.00038; 0.21 ± 0.96, p = 0.87, r2 = 0.00122). These findings confirm the validity of the optimized version of Graal for the measurement of quantitative indexes of gait. Hence, Graal constitutes an extremely time- and cost-efficient tool suitable for quantitative analysis of running. However, its validity for qualitative running gait analysis remains inconclusive and will require further evaluation in a wider range of absolute and relative running intensities in different individuals.

With the rapid development of mobile technology, the mobile phones has gradually become an indispensable part in everybody’s life, and it is replacing the computer’s position step by step. The iPhone is a smart phone made of Apple Company, which opens a new era of software for mobile devices. At the same time, iOS(iPhone’s operating system) has become one of most competitive mobile communications operating systems. The Apple’s protection for security makes the iPhone owners hardly control their phone through the root (highest authority). It is so difficult to manage the information effetely with iPhone, such as contacts’ information or SMS. The paper introduced two approaches to get the contacts’ information in iPhone and restore them with vCard. At last, we managed the output file on MAC.

Purpose The purpose of this paper is to examine alternative six- and seven-factor equity pricing models directed at capturing a new factor, aggregate volatility, in addition to market, size, book to market, profitability, investment premiums of the Fama and French (2015) and Fama and French’s (2018) aggregate volatility augmented model. Design/methodology/approach The models are tested using a time series regression and Fama and Macbeth’s (1973) methodology. Findings The authors show that both six- and seven-factor models best explain average excess returns on the French stock market. In fact, the authors outperform Fama and French’s (2018) model. The authors use sensitivity of aggregate volatility of a stock VCAC as a proxy to construct the aggregate volatility risk factor. The spanning tests suggest that Fama and French’s (1993, 2015, 2018) and Carhart’s (1997) models do not explain the aggregate volatility risk factor FVCAC. The results show that the FVCAC factor earns significant αs across the different multifactor models and even after controlling for the exposure to all the other in Fama and French’s (2018) model. The asset pricing tests show that it is systematically priced. In fact, the authors find a significant and negative (positive) relation between the aggregate volatility risk factor and the excess returns in the French stock market when it is rising (falling), in addition, periods with downward market movements tend to coincide with high volatility. Originality/value The authors contribute to the related literature in several ways. First, the authors test two new empirical six- and seven-factor model and the authors compare them to Fama and French’s (2018) model. Second, the authors give new evidence about the VCAC, using it for the first time to the authors’ knowledge, to construct a volatility risk premium.

The purpose of this article is to explore the teaching processes that use Quick Response (QR) codes and mobile devices to support blended learning at the National Institute of Telecommunications and ICT (INTTIC). The satisfactory results of our previous research show that the use of mobile technology could enhance accessibility and communication in a blended learning course. In Algeria, the mobile penetration rate stands at over 111% and 21% with 3G. Since most of our students have access to mobile technology, three in five were smartphones. Using this technology would encourage students to use their phones to send questions to their teachers, listen to a podcast and snip the quick response (QR) codes. This paper introduces the implementations of QR codes, vcard and QR voice as a new tool in the Moodle platform in our institute. The QR code contains the URL of the page of one particular Moodle course and quiz are added to the bottom of Moodle. The students' satisfaction had been acknowledged as an important factor in order to estimate the effectiveness of a blended learning course.

Abstract Modification dependent restriction endonucleases (MDREs) often have separate catalytic and modification dependent domains. We systematically looked for previously uncharacterized fusion proteins featuring a PUA or DUF3427 domain and HNH or PD-(D/E)XK catalytic domain. The enzymes were clustered by similarity of their putative modification sensing domains into several groups. The TspA15I (VcaM4I, CmeDI), ScoA3IV (MsiJI, VcaCI) and YenY4I groups, all featuring a PUA superfamily domain, preferentially cleaved DNA containing 5-methylcytosine or 5-hydroxymethylcytosine. ScoA3V, also featuring a PUA superfamily domain, but of a different clade, exhibited 6-methyladenine stimulated nicking activity. With few exceptions, ORFs for PUA-superfamily domain containing endonucleases were not close to DNA methyltransferase ORFs, strongly supporting modification dependent activity of the endonucleases. DUF3427 domain containing fusion proteins had very little or no endonuclease activity, despite the presence of a putative PD-(D/E)XK catalytic domain. However, their expression potently restricted phage T4gt in Escherichia coli cells. In contrast to the ORFs for PUA domain containing endonucleases, the ORFs for DUF3427 fusion proteins were frequently found in defense islands, often also featuring DNA methyltransferases.

Contributing to Sustainable Development Goals and Agenda 2030 is a shared objective of all institutions and people. The challenges differ according to the characteristics of every context. In developing countries, strongly dependent on the agricultural sector, agricultural supply chains are recognized as crucial for economic growth and enablers for livelihood improvement. Moreover, sustainable development issues are correlated and can meet in agricultural supply chains. For several decades, parallel to decision-makers, the research community has elaborated sustainability assessment tools. Such tools evolved to fit with actuality, but it is challenging to find decision-making support tools for sustainable development adequate in agricultural supply chains and developing countries contexts. There is a necessity to define evidence-based tools and exhaustive analytical frameworks according to sustainability multidimensionality and strategical tradeoffs necessity. The VCA4D method aims to go beyond the limits of previous methods. It proposes a combination of multidisciplinary analytical tools applied empirically to analyze agricultural supply chains in their context. It provides evidence-based analytical results allowing to identify enablers for strategic sustainable and inclusive interventions. However, to even better meet contextual exhaustiveness’s expectations and indicators’ robustness to lead to relevant interventions, we should insist on a stricter framing of contextual data collection processes.

Abstract In this article, a novel approach to computer optimization of CNC toolpaths by adjustment of cutting speed vcand depth of cut apis presented. Available software works by the principle of adjusting feed rate on the basis of calculations and numerical simulation of the machining process. The authors wish to expand upon this approach by proposing toolpath optimization by altering two other basic process parameters. Intricacies and problems related totheadjustment of apand vcwere explained in the introductory part. Simulation of different variant of the same turning process with different parameter values were conducted to evaluate the effect of changes in depth of cut and cutting speed on process performance. Obtained results were investigated on the account of cutting force and tool life. The authors have found that depth of cut substantially affects cutting force, while the effect of cutting speed on it is minimal. An increase in both depth of cut and cutting speed affects tool life negatively, although the impact of cutting speed is much more severe. An increase in depth of cut allows for a more significant reduction of machining time, while affecting tool life less negatively. On the other hand, the adjustment of cutting speed helpsto reduce machining time without increasing cutting force component values and spindle load.

We analysed fluid dynamics at brain arteries having multiple inflow and out flow like Willis ring based on clinical imaging modalities. In addition, we analysed fluid dynamics with therapeutic devices like coils and stents to simulate their influences to blood flow. 3D CTA and MRA obtained three-dimensional structures of the brain vessels. The centreline was obtained from the three dimensional structure. Diameter of the blood vessels was measured by 3D CTA/MRA then smooth surfaced blood vessel models were created. For the fluid analysis, we developed a home brew software which can display parameters such as streamline, etc. In addition, our CFD (computational fluid dynamics) software can work in collaboration with a CAD (computer aided design) software which we also developed (VCAD: Volume CAD). So, therapeutic devices such as coils, balloons and stents could be placed in the models and CFD analysis could be performed placing devices in the models. The flow pattern in the complicated vascular structure could be calculated such as Willis ring which has multiple inputs like ICA, VA and multiple outlets like MCA and PCA with communicating arteries. CFD with therapeutic devices could also analysed with our system.

Objectives: To determine frequency of left main stem (LMS) and triple vessel coronary artery disease (3VCAD) in patients of Non-ST-elevation myocardial infarction (NSTEMI) and to compare the frequency of LMS and 3VCAD in patients with NSTEMI with or without ST elevation in lead aVR. Methodology: Total 346 patients with NSTEMI having age 30-70 years were included in this descriptive cross-sectional study. The data on demographic details was collected. All patients underwent electrocardiography (ECG) and cardiac specific troponin-I assessment. Patients were categorized as NSTEMI with or without ST-elevation in lead aVR. Coronary angiography was performed in all patients and angiographic findings were noted. Results: Mean age of patients was 51.87±10.03 years. There were 218 (63.01%) males and 128 (36.99%) female patients. 182 (52.60%) patients of NSTEMI had ST elevation in aVR. LMS disease was found in 53 (29.10%) patients with ST elevation in aVR. Sensitivity, specificity, positive predive value and negative predictive value of ST elevation in aVR for LMS disease was 62.35%, 50.57%, 29.12% and 80.49% respectively. 3 VCAD was found in 54 (29.70%) with ST elevation in aVR. Sensitivity, specificity, positive predive value and negative predictive value of ST elevation in aVR for 3VCAD was 77.14%, 53.52%, 29.67% and 90.24% respectively. Conclusion: NSTEMI patients with ST elevation in aVR may have higher chances of having LMS disease or 3VCAD. There is high negative predictive value for ST elevation in aVR to predict LMS disease or 3VCAD.

A haptic sensor coupled to a gamepad or headset is frequently used to enhance the sense of immersion for game players. However, providing haptic feedback for appropriate sound effects involves specialized audio engineering techniques to identify target sounds that vary according to the game. We propose a deep learning-based method for sound event detection (SED) to determine the optimal timing of haptic feedback in extremely noisy environments. To accomplish this, we introduce the BattleSound dataset, which contains a large volume of game sound recordings of game effects and other distracting sounds, including voice chats from a PlayerUnknown’s Battlegrounds (PUBG) game. Given the highly noisy and distracting nature of war-game environments, we set the annotation interval to 0.5 s, which is significantly shorter than the existing benchmarks for SED, to increase the likelihood that the annotated label contains sound from a single source. As a baseline, we adopt mobile-sized deep learning models to perform two tasks: weapon sound event detection (WSED) and voice chat activity detection (VCAD). The accuracy of the models trained on BattleSound was greater than 90% for both tasks; thus, BattleSound enables real-time game sound recognition in noisy environments via deep learning. In addition, we demonstrated that performance degraded significantly when the annotation interval was greater than 0.5 s, indicating that the BattleSound with short annotation intervals is advantageous for SED applications that demand real-time inferences.

Background: The aim of our study was to evaluate the degree of genetic homozygosity in the group of patients with coronary artery disease (CAD), as well as to evaluate morphogenetic variability in CAD patients regarding the presence of investigated risk factors (RF) compared to a control sample of individuals. Additionally, we aimed to evaluate the distribution of ABO blood type frequencies between tested samples of individuals. Methods: This study analyzed individual phenotype and morphogenetic variability of 17 homozygously-recessive characteristics (HRC), by using HRC test in a sample of 148 individuals in CAD patients group and 156 individuals in the control group. The following RF were analyzed: hypertension, diabetes mellitus, hyperlipidemia, and smoking. Results: The mean value of HRC in CAD patients is significantly higher, while variability decreases compared to the control sample (CAD patients: 4.24 ± 1.59, control sample: 3.75 ± 1.69; VCAD-patients = 37.50%, VC = 45.07%). There is a significant difference in individual variations of 17 HRC between control sample and CAD patients (χ2 = 169.144; p < 0.01), which points out to different variability for tested genes. Mean values of HRC significantly differed in CAD patients in regard to the number of RF present. A blood type (OR = 1.75) is significant predictor for CAD, while O blood type (OR = 0.43) was significantly associated with controls. Conclusion: There is a higher degree of recessive homozygosity in CAD patients versus individuals in the control sample, and the presence of significant variations in the degree of recessive homozygosity as the number of tested RF increases.

ABSTRACTRanaviruses (Iridoviridae) are posing an increasing threat to amphibian populations, with anuran tadpoles being particularly susceptible to these viral infections. Moreover, amphibians are the most basal phylogenetic class of vertebrates known to possess both type I and type III interferon (IFN)-mediated immunity. Moreover, little is known regarding the respective roles of the IFN mediators in amphibian antiviral defenses. Accordingly, we transcriptionally and functionally compared the amphibianXenopus laevistype I (IFN) and III (IFN-λ) IFNs in the context of infections by the ranavirus frog virus 3 (FV3).X. laevisIFN and IFN-λ displayed distinct tissue expression profiles. In contrast to our previous findings thatX. laevistadpoles exhibit delayed and modest type I IFN responses to FV3 infections compared to the responses of adults, here we report that tadpoles mount timely and robust type III IFN gene responses. Recombinant forms of these cytokines (recombinantX. laevisIFN [rXlIFN] and rXlIFN-λ) elicited antiviral gene expression in the kidney-derived A6 cell line as well as in tadpole leukocytes and tissues. However, rXlIFN-λ was less effective than rXlIFN in preventing FV3 replication in A6 cells and tadpoles and inferior at promoting tadpole survival. Intriguingly, FV3 impaired A6 cell and tadpole kidney type III IFN receptor gene expression. Furthermore, in A6 cultures rXlIFN-λ conferred equal or greater protection than rXlIFN against recombinant viruses deficient for the putative immune evasion genes, the viral caspase activation and recruitment domain (vCARD) or a truncated vIF-2α gene. Thus, in contrast to previous assumptions, tadpoles possess intact antiviral defenses reliant on type III IFNs, which are overcome by FV3 pathogens.IMPORTANCEAnuran tadpoles, including those ofXenopus laevis, are particularly susceptible to infection by ranavirus such as FV3. We investigated the respective roles ofX. laevistype I and type III interferons (IFN and IFN-λ, respectively) during FV3 infections. Notably, tadpoles mounted timely and more robust IFN-λ gene expression responses to FV3 than adults, contrasting with the poorer tadpole type I IFN responses. However, a recombinantX. laevisIFN-λ (rXlIFN-λ) conferred less protection to tadpoles and the A6 cell line than rXlIFN, which may be explained by the FV3 impairment of IFN-λ receptor gene expression. The importance of IFN-λ in tadpole anti-FV3 defenses is underlined by the critical involvement of two putative immune evasion genes in FV3 resistance to IFN- and IFN-λ-mediated responses. These findings challenge the view that tadpoles have defective antiviral immunity and suggest, rather, that their antiviral responses are predominated by IFN-λ responses, which are overcome by FV3.

Antecedentes: el duelo anticipado es el proceso por el que pasan algunas personas antes del fallecimiento de un ser querido o de que se confirme su muerte. Ocurre cuando varias circunstancias hacen prever que tarde o temprano un ser querido, como un familiar, una pareja o un amigo, va a morir. Objetivo: el objetivo de estudio fue conocer cuáles son las estrategias de afrontamiento al estrés y factores personales del cuidado y del cuidador que benefician o ponen en riesgo el duelo anticipado en cuidadores informales de personas de la tercera edad. Método: participaron 272 cuidadores informales. Se utilizó la Escala del Duelo en el Cuidador de Meichsner et al. (2016) y la Escala Breve de Afrontamiento al Estrés (COPE 28) de Carver (1997). Resultados: los resultados evidencian que el duelo anticipado es influenciado por el afrontamiento: el dolor emocional por el afrontamiento basado en apoyo (OR = .236), afrontamiento evasión a la emoción (OR = 3.751) y estar todo el día de cuidado (OR = 3.061). La pérdida emocional es estimada por el afrontamiento focalizado en el problema (OR = .201), cuando el cuidador es un adulto mayor (OR = .303) y por el medio tiempo de cuidado (OR = 2.029). La aceptación de la pérdida es influenciada por el afrontamiento focalizado al problema (OR = .172), afrontamiento evasión a la emoción (OR = 4.409), cuidador es adulto joven (OR = 2.361) y por el cuidado durante casi todo el día (OR = .536). Además, la pérdida absoluta se asoció con el afrontamiento focalizado en el problema (r = .249) y el afrontamiento de evasión con sustancias (r = .216). Conclusiones: este estudio logra identificar factores personales y tipos de afrontamiento al estrés que favorecen o disminuyen el duelo anticipado en el cuidador primario informal. Particularmente, la probabilidad de presentar dolor emocional aumenta de acuerdo al afrontamiento basado en el apoyo o el espiritual, pero disminuye con el afrontamiento basado en la evasión emocional y la mayor convivencia con el enfermo.

Fruit acidity is an essential factor affecting blueberry organoleptic quality. The organic acid content in blueberry fruit mainly contributes to fruit acidity. This study aims to evaluate the effect of exogenous salicylic acid (SA), the principal metabolite of aspirin, on the organoleptic quality and organic acid metabolism in rabbiteye blueberry (Vaccinium virgatum Ait, ‘Powderblue’) during cold storage (4 °C). Results showed that SA-treated fruit reduced fruit decay and weight loss delayed fruit softening, and decline of total soluble solids (TSS). TA and total organic acid amounts stayed the same during the late storage period in SA-treated fruit. Four kinds of organic acid components, malic acid, quinic acid, citric acid, and succinic acid, were at higher levels in fruit treated by SA as compared to control. SA enhanced the activities of PEPC, NAD-MDH, and CS to promote the synthesis of malic acid and citric acid. Meanwhile, the activities of NADP-ME, ACL, and ACO, which participated in the degradation of malic acid and citric acid, were inhibited by SA. qPCR results also showed that the expression of VcPEPC, VcNAD-MDH, and VcCS genes were upregulated. In contrast, SA downregulated the expression of VcNADP-ME, VcACL, and VcACO genes. In conclusion, SA could regulate the key genes and enzymes that participated in organic acids metabolism to maintain the freshness of blueberry during cold storage, therefore minimizing the economic loss.

Abstract Background Percutaneous tricuspid valve edge-to-edge repair (pTVR) is a promising interventional technique for patients with tricuspid regurgitation (TR), but guidance regarding patient selection and echocardiographic screening is lacking. The aim of this study was to identify echocardiographic parameters which may predict pTVR success. Methods Before and after pTVR, echocardiographic data, including 3D full-volume datasets, were obtained and quantified. Right ventricular assessments included ejection fraction (RVEF3D) and diastolic (RVVd3D) and systolic (RVVs3D) volumes. Also evaluated were: right atrial (RA) volume, effective regurgitant orifice area by PISA method (EROAPISA), vena contracta area (VCA3D) by multiplanar reconstruction from a 3D colour Doppler loop (Figure 1a), maximal diastolic tricuspid annulus area from a 3D zoom image (Figure 1b), and tricuspid tenting area. TR severity was graded according to EROAPISA and VCA3D as grade 1+ to 5+. Results Patients (n=99, age 79±6 years, 48 male) with at least moderate to severe TR undergoing pTVR were consecutively included. The patients were divided into groups according to their post-pTVR TR grade. Group 1 had TR grade ≤2+, and group 2 had TR grade ≥3+.Echocardiographic parameters before pTVR for both groups are presented in Table 1. As expected, patients with TVR ≥3+ after pTVR had significantly worse pre-intervention echocardiographic measurements of TR severity, valve dimensions, and chamber volumes. ROC curves for the prediction of TR ≤2+ (mild to moderate) after pTVR (defined as VCA3D <0.75 cm2 and EROAPISA <0.4 cm2) were drawn for different echocardiographic features (Figure 2). VCA3D by 3D colour Doppler yielded the highest area under the ROC curve followed by TV anatomy measurements (Annulus area3D, Tenting area) and right atrial volume. Conclusion A thorough evaluation of TR and valve dimensions by 3D echocardiography, particularly the evaluation of VCA3D by 3D colour Doppler, aids in the prediction of the probability of pTVR success.
