Abstract:

For decoding the asynchronous superposition of response signals from different sensors, it is a challenge to achieve correlation in a code division multiplexing (CDM) based passive wireless surface acoustic wave (SAW) multisensor system. Therefore, an on-chip correlator scheme is developed in this paper. In contrast to conventional CDM-based systems, this novel scheme enables the correlations to be operated at the SAW sensors, instead of the reader. Thus, the response signals arriving at the reader are the result of cross-correlation on the chips. It is then easy for the reader to distinguish the sensor that is matched with the interrogating signal. The operation principle, signal analysis, and simulation of the novel scheme are described in the paper. The simulation results show the response signals from the correlations of the sensors. A clear spike pulse is presented in the response signals, when a sensor code is matched with the interrogating code. Simulations verify the feasibility of the on-chip correlator concept.

Abstract:

To evaluate the pathogenetic role of cerebral blood flow (CBF) changes occurring before and during the development of acute mountain sickness (AMS), peak mean middle cerebral artery flow velocities ([Formula: see text]) were assessed by transcranial Doppler sonography in 10 subjects at 490-m altitude, and during three 12-min periods immediately (SA1), 3 (SA2), and 6 (SA3) h after decompression to a simulated altitude of 4,559 m. AMS cerebral scores increased from 0.16 ± 0.14 at baseline to 0.44 ± 0.31 at SA1, 1.11 ± 0.88 at SA2( P < 0.05), and 1.43 ± 1.03 at SA3( P < 0.01); correspondingly, three, seven, and eight subjects had AMS. Absolute and relative[Formula: see text] at simulated altitude, expressed as percentages of low-altitude values (%[Formula: see text]), did not correlate with AMS cerebral scores. Average %[Formula: see text] remained unchanged, because %[Formula: see text]increased in three and remained unchanged or decreased in seven subjects at SA2 and SA3. These results suggest that CBF is not important in the pathogenesis of AMS and shows substantial interindividual differences during the first hours at simulated altitude.

Abstract:

Abstract Hepatic mRNA levels of the mouse major acute phase proteins serum amyloid P component (SAP) and serum amyloid A component (SAA) were monitored at timed intervals after i.p. injection of thioglycollate or s.c. injection of azocasein. Both mRNA increased dramatically in response to either inflammatory stimulus. The increase in SAA mRNA levels accompanied an abrupt change in mRNA size from 650 to 750 bases. Peak SAA mRNA concentrations were observed 18 h after either stimulus; by 72 h concentrations had returned to preinflammatory levels. Peak SAP mRNA concentrations were observed 8 h after thioglycollate and 12 to 18 h after azocasein injection; by 36 h concentrations were close to preinflammatory levels. All mRNA species studied (SAP, SAA and the complement components C3, C5 and factor B) were induced more rapidly by the thioglycollate stimulus and reached higher peak concentrations. SAP mRNA levels were correlated with other parameters of inflammation: infiltration of peritoneal exudate cells (PEC) into the peritoneum after thioglycollate injection, and serum concentrations of SAP after azocasein injection. Serum SAP concentrations rose 20-fold in response to the latter stimulus by 36 h, i.e., 18 to 24 h after the peak SAP mRNA levels. The highest numbers of PEC were present 24 h after the thioglycollate stimulus, i.e. 16 h after the maximum SAP mRNA concentration, indicating the continuation of an active local inflammation many hours after one aspect of the systemic response has ceased.

Abstract:

Background Situation awareness (SA) is defined in three levels: SA1 is the perception of the elements in a specific context, SA2 is the comprehension of their meaning, and SA3 is the projection of their status. Purpose To analyze the possible association of a genetic polymorphism in the serotonin transporter ( SLC6A4) gene and performance on the Situational Awareness test (SAtest). Methods SAtest was applied to a sample of 230 healthy Colombian subjects, using the Psychology Experiment Building Language platform and a functional polymorphism in the SLC6A4 gene was genotyped by polymerase chain reaction. Results In the SA1 level, s/s genotype carriers had worse accuracy, in comparison with s/l and l/l genotypes. At SA2 level, l/l genotype carriers had better accuracy than s/s and s/l individuals and that in the SA3 level, l/l carriers also had better accuracy. These associations were significant after correction for multiple testing. Conclusions It is possible that l/l carriers have a better ability to perceive and focus their attention on the elements of their environment and to have the capacity to understand and predict what will happen with those elements. This is the first genetic study of SA performance in healthy participants. Additional investigations of other genes could contribute to the understanding of the molecular correlates of SA in healthy subjects and in neuropsychiatric patients.

Abstract:

Abstract Background: The relative changes in plasma and intracellular concentrations of S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) may be important predictors of cellular methylation potential and metabolic alterations associated with specific genetic polymorphisms and/or nutritional deficiencies. Because these metabolites are present in nanomolar concentrations in plasma, methods of detection generally require time-consuming precolumn processing or metabolite derivatization. Methods: We used HPLC with coulometric electrochemical detection for the simultaneous measurement of SAM and SAH in 200 μL of plasma, 106 lymphocytes, or 10 mg of tissue. Filtered trichloroacetic acid extracts were injected directly into the HPLC system without additional processing and were eluted isocratically. Results: The limits of detection were 200 fmol/L for SAM and 40 fmol/L SAH. In plasma extracts, the interassay CV was 3.4–5.5% and the intraassay CV was 2.8–5.6%. The analytical recoveries were 96.8% and 97.3% for SAM and SAH, respectively. In a cohort of healthy adult women with mean total homocysteine concentrations of 7.3 μmol/L, the mean plasma value was 156 nmol/L for SAM and 20 nmol/L for SAH. In women with increased homocysteine concentrations (mean, 12.1 μmol/L), plasma SAH, but not SAM, was increased (P <0.001), and plasma pyridoxal 5′-phosphate concentrations were reduced (P <0.001). Plasma SAM/SAH ratios were inversely correlated with homocysteine concentrations (r = 0.73; P <0.01), and the SAM/SAH ratio in plasma was directly correlated with the intracellular SAM/SAH ratio in lymphocytes (r = 0.70; P <0.01). Conclusions: Increased homocysteine in serum is associated with an increase in SAH and a decrease in the SAM/SAH ratio that could negatively affect cellular methylation potential. Accurate and sensitive detection of these essential metabolites in plasma and in specific tissues should provide new insights into the regulation of one-carbon metabolism under different nutritional and pathologic conditions.

Abstract:

Background and aimsWe hypothesised that intracellular homocysteine and homocysteine metabolite levels in patients with SLE are disproportionately elevated compared with the levels seen in healthy subjects and that they are independently associated with coronary plaque in SLE.MethodsA liquid chromatography–tandem mass spectrometry absolute quantification assay was used for the determination of six analytes in both plasma and peripheral blood mononuclear cells (PBMCs): homocysteine (Hcy), S-adenosylmethionine (SAM), S-adenosylhomocysteine (SAH), methionine (Met), cystathionine (Cysta) and 5-methyltetrahydrofolate (5m-THF). We then compared intracellular (PBMC) and extracellular (plasma) Hcy and Hcy metabolite (SAM, SAH, Met, Cysta and 5m-THF) concentrations in 10 patients with SLE and in 10 age, sex and ethnicity matched controls. Subjects with a history of diabetes mellitus, cardiovascular disease, hypertension, alcohol consumption in excess of 3 units per day, anaemia, renal insufficiency (serum creatinine >1.5 mg/dL) and pregnancy were excluded. All patients with SLE had two coronary CT angiography studies as screening for occult coronary atherosclerotic disease.ResultsPlasma from patients with SLE had higher levels of Hcy (p<0.0001), SAH (p<0.05), SAM (p<0.001) and lower levels of Met (p<0.05) and Cysta (p<0.001) compared with controls. PBMC intracellular concentrations from patients with SLE had higher levels of Cysta (p<0.05), SAH (p<0.05), SAM (p<0.001) and lower levels of 5m-THF (p<0.001). Plasma SAH showed a positive correlation with total coronary plaque, calcified plaque and non-calcified plaque (p<0.05).ConclusionIntracellular concentrations of Hcy metabolites were significantly different between patients with SLE and controls, despite similar intracellular Hcy levels. Plasma SAH was positively correlated with total coronary plaque, calcified plaque and non-calcified plaque.

Abstract:

Abstract Background: B-vitamins (folate, B12) are important micronutrients for brain function and essential cofactors for homocysteine (HCY) metabolism. Increased HCY has been related to neurological and psychiatric disorders. We studied the role of the B-vitamins in HCY metabolism in the brain. Methods: We studied blood and cerebrospinal fluid (CSF) samples from 72 patients who underwent lumbar puncture. We measured HCY, methylmalonic acid (MMA), and cystathionine by gas chromatography-mass spectrometry; S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) by liquid chromatography-tandem mass spectrometry; and the B-vitamins by HPLC or immunoassays. Results: Concentrations were lower in CSF than serum or plasma for HCY (0.09 vs 9.4 μmol/L), SAH (13.2 vs 16.8 nmol/L), cystathionine (54 vs 329 nmol/L), and holotranscobalamin (16 vs 63 pmol/L), whereas concentrations in CSF were higher for MMA (359 vs 186 nmol/L) and SAM (270 vs 113 nmol/L; all P <0.05). CSF concentrations of HCY correlated significantly with CSF folate (r = −0.46), CSF SAH (r = 0.48), CSF-albumin (r = 0.31), and age (r = 0.32). Aging was also associated with lower concentrations of CSF-folate and higher CSF-SAH. The relationship between serum and CSF folate depended on serum folate: the correlation (r) of serum and CSF-folate was 0.69 at serum folate <15.7 nmol/L. CSF concentrations of MMA and holotranscobalamin were not significantly correlated. Conclusions: CSF and serum/plasma concentrations of vitamin biomarkers are significantly correlated. Older age is associated with higher CSF-HCY and CSF-SAH and lower CSF-folate. These metabolic alterations may be important indicators of low folate status, hyperhomocysteinemia, and neurodegenerative diseases.

Abstract:

Background and Purpose: Delayed neurological deficits are a devastating consequence of subarachnoid hemorrhage (SAH), which affects about 30% of surviving patients. Although a very serious concern, delayed deficits are understudied in experimental SAH models; it is not known whether rodents recapitulate the delayed clinical decline seen in SAH patients. We hypothesized that mice with SAH develop delayed functional deficits and that microthrombi and infarction correlate with delayed decline. Methods: Adult C57BL/6J mice of both sexes were subjected to endovascular perforation to induce SAH. Mice were allowed to survive for up to 1 week post-ictus and behavioral performance was assessed daily. Postmortem microthrombi, large artery diameters (to assess vasospasm), and infarct volume were measured. These measures were analyzed for differences between SAH mice that developed delayed deficits and SAH mice that did not get delayed deficits. Correlation analyses were performed to identify which measures correlated with delayed neurological deficits, sex, and infarction. Results: Twenty-three percent of males and 47% of females developed delayed deficits 3 to 6 days post-SAH. Female mice subjected to SAH had a significantly higher incidence of delayed deficits than male mice with SAH. Mice that developed delayed deficits had significantly more microthrombi and larger infarct volumes than SAH mice that did not get delayed deficits. Microthrombi positively correlated with infarct volume, and both microthrombi and infarction correlated with delayed functional deficits. Vasospasm did not correlate with either infarction delayed functional deficits. Conclusions: We discovered that delayed functional deficits occur in mice following SAH. Sex differences were seen in the prevalence of delayed deficits. The mechanism by which microthrombi cause delayed deficits may be via formation of infarcts.

Abstract:

The linkage of the South Asian High (SAH) to the southern annular mode (SAM) during the boreal summer is addressed. The results show that the SAH correlated well with the Southern Hemispheric subtropical high (SSH) and SAM, which exhibits that their recent positive trends are associated with each other. During the positive SAH anomalies years, roughly speaking, the sea level pressure (SLP) and the zonal surface wind (u10) are analogous to that of the positive SAM phase, but they also show an anomalous zonal-wave-3-like (ZW3-like) pattern over the mid latitudes. The surface temperature (ST) variations are not similar to the SAM. Nevertheless, these changes are related with the anomalous cyclones and meridional surface wind (v10). The relationship between the SAH and SAM is also a manifestation of the interhemispheric interaction, and this study contributes to the understanding of the global change.

Abstract:

Previously, we showed that feeding micropigs ethanol with a folate-deficient diet promoted the development of hepatic injury while increasing hepatic levels of homocysteine and S-adenosylhomocysteine (SAH) and reducing the level of S-adenosylmethionine (SAM) and the SAM-to-SAH ratio. Our present goals were to evaluate mechanisms for hepatic injury using liver specimens from the same micropigs. The effects of ethanol feeding or folate-deficient diets, singly or in combination, on cytochrome P-450 2E1 (CYP2E1) and signal pathways for apoptosis and steatosis were analyzed using microarray, real-time PCR, and immunoblotting techniques. Apoptosis was increased maximally by the combination of ethanol feeding and folate deficiency and was correlated positively to liver homocysteine and SAH. Liver CYP2E1 and the endoplasmic reticulum stress signals glucose-regulated protein 78 (GRP78), caspase 12, and sterol regulatory element binding protein-1c (SREBP-1c) were each activated in pigs fed folate-deficient or ethanol diets singly or in combination. Liver mRNA levels of CYP2E1, GRP78, and SREBP-1c, and protein levels of CYP2E1, GRP78, nuclear SREBP, and activated caspase 12 each correlated positively to liver levels of SAH and/or homocysteine and negatively to the SAM-to-SAH ratio. The transcripts of the lipogenic enzymes fatty acid synthase, acetyl-CoA carboxylase, and stearoyl-CoA desaturase were elevated in the ethanol-fed groups, and each was positively correlated to liver homocysteine levels. The induction of abnormal hepatic methionine metabolism through the combination of ethanol feeding with folate deficiency is associated with the activation of CYP2E1 and enhances endoplasmic reticulum stress signals that promote steatosis and apoptosis.

Abstract:

The Holy Quran is one of the Prove of the Prophethood of the Muhammad S(SAW). It is the greatest miracle of the Holy Prophet (SAW) and as a challenge to the human beings and jins, no one could bring an example like this. One part of this miracle of the Holy Quran is its correlation among the verses and suras. Islamic scholars like; Imame Razi, Allama Zarakshi, Imame Buqa’I, Imame Syuti, Allama Anwar Shah Kashmiri and others say that The Holy Quran is correlated from start to end and it is the prove that it is the word of Allah. In the lexical meaning “correlation” means “being alike” or “to bring into order” while idiomatically it discusses the correlationship among some parts of the Holy Quran with other and its hidden relation. All the verses of the Holy Quran are correlated in one way or the other. This correlation is sometimes very clear but sometimes it is vague. Some of these hidden correlation are named sometimes but many times it cannot be named but they can be understood by having a natural ability and vast study of the Holy Quran. This research article discusses these correlations which can be discussed and named and many of the scholars (specially the exegesits) have discussed in their books which are pointed to here.

Abstract:

Abstract The serum amyloid A (SAA) protein has been implicated in the pathogenesis of several chronic inflammatory diseases. Its induction mechanism in response to a chronic inflammatory condition was investigated in rabbits following multiple s.c. injections of AgNO3 over a period of 35 days. During unremitting exposure to inflammatory stimulus, a persistently higher than normal level of SAA2 expression was seen in multiple tissues. Induction of SAA was correlated with higher levels of several transcription factor activities. Increased SAA-activating factor (SAF) activity was detected in the liver, lung, and brain tissues under both acute and chronic inflammatory conditions. In the heart, kidney, and skeletal muscle tissues, this activity remained virtually constant. In contrast, CCAAT enhancer binding protein (C/EBP) DNA-binding activity was transiently induced in selective tissues. Higher than normal NF-κB DNA-binding activity was detected in the lung and to a lesser extent in the liver and kidney tissues under both acute and chronic conditions. This result suggested that C/EBP, SAF, and NF-κB are required for transient acute phase induction of SAA whereas SAF and NF-κB activities are necessary for persistent SAA expression during chronic inflammatory conditions.

Abstract:

Background Facebook can be a suitable platform for public health interventions. Facebook users can express their reaction to the given social media content in many ways using interaction buttons. The analysis of these interactions can be advantageous in increasing reach and engagement of public health interventions. Objective This research aimed at understanding how Facebook users’ interactions correlate with organic reach and engagement regarding the same smoking cessation support contents. Methods The study population consisted of Facebook users who were reached by a public smoking cessation support page without advertising. We included 1025 nonpaid Facebook posts (N=1025) which used smoking cessation strategies based on a motivational interviewing counseling style. The following data were collected from the “Post Details”: the number of people who saw the given nonpaid content (organic reach) which consisted of fan and nonfan reach according to previous “page like” activity; each rate of “engagement indicators” (such as the symbols of “like,” “love,” “haha,” “wow,” “sad,” “angry”; or other interactions: “shares,” “comments,” “clicks”); and the rate of negative Facebook interactions (eg, “post hides” or “unlike of page”). Overall, these data were analyzed with the Spearman correlation method. Results Surprisingly, we found a significant negative correlation between organic reach and the “like” reaction (rs=–0.418; P<.001). The strongest significant positive correlations of organic reach were observed with the “haha” reaction (rs=0.396; P<.001), comments (rs=0.368; P<.001), and the “love” reaction (rs=0.264; P<.001). Furthermore, nonfan reach correlated positively with “shares” (rs=0.388; P<.001) and clicks (rs=0.135; P<.001), while fan reach correlated positively with the “haha” reaction (rs=0.457; P<.001), comments (rs=0.393; P<.001), and the “love” reaction (rs=0.310; P<.001). Contrary to expectations, the “like” reaction was sharply separated by significant negative correlations from “wow” (rs=–0.077; P=.013), “sad” (rs=–0.120; P<.001), “angry” reactions (rs=–0.136; P<.001), and comments (rs=–0.130; P<.001). Additionally, a high rate of negative Facebook interactions was significantly associated with “wow” (rs=0.076; P=.016) and “sad” reactions (rs=0.091; P=.003). Conclusions This study has shown that it is possible to hypothesize a disadvantage of the “like” reaction and advantages of other interactions (eg, the “haha” reaction or “comments”) in content algorithmic ranking on Facebook. In addition, the correlational analysis revealed a need of a further categorization to fan-specific interactions (eg, “haha” or “love” reactions) and nonfan-specific interactions (eg, “shares” and “clicks”). Regarding the direction of the correlations, these findings suggest that some interactions (eg, negative Facebook interactions, “wow,” “sad,” and “angry” reactions) may decrease the engagement, while other interactions (“like,” “love,” “haha” reactions, “shares,” and “clicks”) may increase the engagement during Facebook-based smoking cessation interventions. This hypothesis-generating research offers an important insight into the relationship between organic reach, engagement, and Facebook users’ interactions for public health professionals who design Facebook-based interventions.

Abstract:

Thermal dissipation sap flow rate probe was used to measure trunk sap flow dynamic of Poplar during the growing season from September 2011 to May 2012 in coastal region of China. The relationship of trunk sap flow rate and meteorological factors was analyzed. The results showed that the process of sap flow rate of Poplar presented an obvious day and night alternate phenomenon. The diurnal variation of sap flow was a single-peak curve in sunny day and a multi-peak curve in rainy day. According to Pearson correlation analysis, the diurnal sap flow rate of Poplar was positively correlated with solar radiation and atmospheric temperature, and negatively correlated with air relative humidity. The regression analysis showed that there was a significant correlation between multi-day sap flow rate and solar radiation, and the determination coefficient was 0.287 and 0.778 in summer and autumn, respectively. The linear regression model of multi-day sap flow with meteorological multi-factor was remarkable correlation, and the determination coefficient was 0.577 and 0.791 in summer and autumn, respectively. The regression model of multi-day sap flow with meteorological multi-factor was better than with single meteorological factor.

Abstract:

Until now, the ability to form a self-assembled monolayer (SAM) on a surface has been investigated according to deposition techniques, which in turn depend on surface–coater interactions. In this paper, we pursued two goals: to form a SAM on a gold nanosurface and to correlate its formation to the nanosurface curvature. To achieve these objectives, gold nanoparticles of different shapes (spheres, rods, and triangles) were functionalized with a luminescent thiolated bipyridine (Bpy-SH), and the SAM formation was studied by investigating the photo-physics of Bpy-SH. We have shown that emission wavelength and excited-state lifetime of Bpy-SH are strongly correlated to the formation of specific aggregates within SAMs, the nature of these aggregates being in close correlation to the shape of the nanoparticles. Micro-Raman spectroscopy investigation was used to test the SERS effect of gold nanoparticles on thiolated bipyridine forming SAMs.

Abstract:

Background.Microvascular dysfunction and microthrombi formation are believed to contribute to development of early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (SAH).Objective.This study aimed to determine (i) extent of microthrombus formation and neuronal apoptosis in the brain parenchyma using a blood shunt SAH model in rabbits; (ii) correlation of structural changes in microvessels with EBI characteristics.Methods.Acute SAH was induced using a rabbit shunt cisterna magna model. Extent of microthrombosis was detected 24 h post-SAH (n=8) by fibrinogen immunostaining, compared to controls (n=4). We assessed apoptosis by terminal deoxynucleotidyl transferase nick end labeling (TUNEL) in cortex and hippocampus.Results.Our results showed significantly more TUNEL-positive cells (SAH: 115 ± 13; controls: 58 ± 10;P=0.016) and fibrinogen-positive microthromboemboli (SAH: 9 ± 2; controls: 2 ± 1;P=0.03) in the hippocampus after aneurysmal SAH.Conclusions.We found clear evidence of early microclot formation in a rabbit model of acute SAH. The extent of microthrombosis did not correlate with early apoptosis or CPP depletion after SAH; however, the total number of TUNEL positive cells in the cortex and the hippocampus significantly correlated with mean CPP reduction during the phase of maximum depletion after SAH induction. Both microthrombosis and neuronal apoptosis may contribute to EBI and subsequent DCI.

Abstract:

Phenylephrine infusion (PE) has been used to raise arterial pressure (BP) in order to investigate reflex responses mediated by sinoaortic baroreflexes (SAB). Increases in cardiac filling pressures have been reported during PE. Our experiments determined whether PE selectively activates SAB without activation of vagal cardiopulmonary baroreflexes (CPR). We measured changes in mean BP, mean pulmonary arterial pressure (PAP), and renal sympathetic nerve activity (RSNA) during PE in alpha-chloralose-anesthetized dogs before and after sinoaortic denervation (SAD; n = 10), selective vagotomy (n = 9), or SAD and vagotomy (n = 4). PE elevated both BP and PAP in all dogs studied. In dogs with SAB and CPR intact, RSNA was reflexively inhibited (% change RSNA: -76.3 +/- 4.7). In SAD dogs, inhibition of RSNA was significantly attenuated but not abolished (% change RSNA: -27.5 +/- 11.8). This inhibition after SAD correlated closely with increases in PAP. Small BP changes (10 mmHg) were associated with insignificant changes in PAP and RSNA. Volume expansion after SAD produced changes in PAP and RSNA similar to those produced by PE. After selective vagotomy, the sensitivity (% change RSNA/mmHg change BP) of the reflex elicited by PE was significantly decreased (-2.7 +/- 0.03 pre vs. -1.8 +/- 0.12 post; P = 0.01). PE failed to change RSNA after combined SAD and vagotomy. We conclude that vagal CPR contribute to reflex inhibition of RSNA during PE except when elevations of BP are small.

Abstract:

Development of a nondestructive evaluation (NDE) method to detect nascent hydrogen embrittlement (HE) in electroplated high-strength steel parts is becoming important for the aerospace industry. This research investigates the feasibility of surface acoustic waves (SAWs) measurements to distinguish between cadmium (Cd) plated SAE 4340 steel samples with low and high HE susceptibilities. SAWs were generated with a 10 MHz piezoelectric transducer and detected by line scans via a laser Doppler vibrometer setup. Using signal processing algorithms in MATLAB, SAW velocities as well as attenuation coefficients were estimated. Depth profiles of steel hardness near coatings were also evaluated using Vickers microindentation tests. Average steel hardness in not-baked samples was slightly increased. Cd coatings were characterized by laser and optical microscopy methods. Small variations found in thickness and surface roughness of the Cd coatings among the samples did not significantly affect the NDE results. On average, samples in the not-baked condition (high HE risk) exhibited lower SAW attenuation coefficients compared to immediately baked and late-baked conditions (low HE risk). However, it was not possible to distinguish between the manufacturing conditions of individual samples due to overlaps in attenuation measurement results. SAW velocities as estimated by the cross-correlation method were found to be not sensitive to manufacturing conditions.

Abstract:

Recipes are used as a reference in processing cooking ingredients to meet personal nutritional needs, considering the ingredients used to make food sold freely that is not necessarily guaranteed in nutritional quality and safe to consume, especially during the pandemic as it is today. So cooking itself becomes a better alternative for the community. With a large number of food recipe options available for various media, the role of a Decision Support System is needed by people who will get food recipe recommendations. Research related to recipe recommendations that have been done are using SAW only and some add experts as a source of knowledge to provide value on the variable time and complexity of cooking recipes. Therefore, in this study, a comparison between the research of recipe recommendations with SAW only and research that added a subsystem of knowledge management derived from experts to support the decision support system of food recipe recommendations was conducted by using correlation testing. The results is there is a strong correlation between knowledge based SAW and user preference to the value of 0.9774. The result is better than SAW only and user preference with the value of 0.7262.

Abstract:

Saffron is an important flowering plant, generally known as a golden condiment. The present study was performed to find the influence of different levels of SA and pre-cold treatment in the dormancy period of saffron and their effects on content enzyme activity. The results indicated that the SA2%, SA1%, and, pre-cold treatments took the shortest day to flowering. PAL enzyme activity was highest in pre-cold treatment. The higher total amount of protein was measured in the control, SA1% and SA2%. The highest amount of starch content and total soluble sugar was detected in pre-cold, SA2%, and control, respectively. No significant differences between treatments were present for CAT, PPO, GPX, and APX enzymes activity. There was a negative significant correlation between flowering time and some studied traits, i.e., starch and PAL activity. Applying SA and pre-cold treatment can induce saffron flowering and effect on pal enzyme activity and corm total protein, sugar, and starch content accordingly.

AbstractObjectives:(1) To study the prevalence and characteristics of large endolymphatic sac internal compartments on thin-section T2- and T2*-weighted magnetic resonance imaging, and to relate these to other large endolymphatic sac magnetic resonance imaging features, and (2) to correlate the compartment imaging features, endolymphatic sac size and labyrinthine anomalies with the patients' clinical and audiological data.Method:Magnetic resonance imaging studies for 38 patients with large endolymphatic sac anomalies were retrospectively reviewed in a tertiary referral centre. Endolymphatic sac compartment presence, morphology and imaging signal were assessed. Endolymphatic sac size and labyrinthine anomalies were also recorded. Endolymphatic sac compartments and other imaging features were correlated with clinical and audiological data.Results:Compartments were present in 57 per cent of the imaged endolymphatic sacs, but their presence alone did not correlate with other imaging features or clinical data. The endolymphatic sac : internal auditory meatus signal ratio was associated with a history of sudden or fluctuating hearing loss. Hearing loss correlated with opercular and extraosseous endolymphatic sac size measurements. A larger midpoint intraosseous endolymphatic sac size was associated with clear fluid loss at cochlear implantation.Conclusion:The magnetic resonance imaging characteristics of large endolymphatic sac compartments have been defined. The endolymphatic sac size and distal compartment signal should be recorded, as these provide prognostic information and assist the planning of appropriate interventions.

Abstract:

2080 Background: Financial conflict of interest (COI) represents a complex issue in hematology and oncology. Little is known about when COIs develop during a career and if these correlate with early career success. We evaluated self-reported COIs for junior faculty members at 10 academic cancer centers and examined if these financial relationships with industry correlated with measures of academic career success. Methods: The study evaluated 229 assistant professors from the top 10 cancer centers based on the 2018 US News Cancer rankings. Faculty characteristics were determined from hospital websites including the number of years since completing fellowship. Data regarding National Institute of Health (NIH) funding were obtained. Industry funds (Sunshine Act funds; SAF) were identified from the Centers for Medicare & Medicaid Services (CMS) Open Payments database from 2013-2017. Self-reported COIs were obtained from the American Society of Clinical Oncology (ASCO) or American Society of Hematology (ASH) disclosures databases, and through review of disclosures from recent publications. Measures of academic success included h-index and number of publications. We assessed the influence of number of COIs and SAF received on measures of academic success. Results: Of the 229 included faculty, 45% were female, 39% graduated fellowship in 2015 or later, 35% were double-boarded, 40% had dual degrees and 15% received NIH funding. Approximately 46% of faculty had at least 1 COI. COIs (ASCO/ASH) were positively correlated with COIs self-reported in publications and total SAF (Spearman correlations 0.57 and 0.54, both P < 0.01). The development of COIs and the number of SAF increased with years in practice (Spearman correlations 0.37 and 0.28, both P < 0.01). COIs and SAF correlated with h-index (Spearman correlation 0.40 and 0.41, both P < 0.01). After adjusting for years since fellowship, linear regression demonstrated that log-transformed h-index and number of publications were associated with SAF (P < 0.01) and COIs (ASCO/ASH) (P = 0.01). Conclusions: Financial COIs were present in nearly half of the faculty and increased with more time since completing fellowship. Measures of academic success were positively correlated with COIs (ASCO/ASH) and SAF. These data suggest that cultivating industry relationships may aid faculty in establishing early academic success.

Abstract:

An attempt has been made to correlate the monthly incidence of human leishmaniasis with the temporal distribution of sandfly species at San Esteban, Northern Venezuela. Upon statistical analysis, the seasonal fluctuation of L. ovallesi population correlated strongly with the human disease, while the dynamics of L. panamensis, generally believed to be the vector in the Central area of the country, showed only a very weak correlation. These findings support the hypothesis that L. panamensis might not be the main or unique species responsible for the transmission in this area and that L. ovallesi and additionally L. olmeca bicolor might be involved in the epidemiology of the disease.

Abstract:

AbstractPrevious work in the San Luis Valley of south-central Colorado and northern New Mexico at the Hansen Bluff and SAM Cave localities has allowed reconstruction of the paleoclimate in the region during the interval from ∼0.6 myr to ∼2.6 myr. Surface exposures at Hansen Bluff have been correlated to deep-sea oxygen isotope core stages 18–23 and one of the glacial periods contained therein to the oldest “Nebraskan” till in southwestern Iowa. Deposits in SAM Cave correlate to Hansen Bluff on the basis of paleomagnetics, climate interpretation, and microtine rodent biochronology. In this paper, carbon and oxygen stable isotope data of herbivorous rodent teeth are used as indicators of change in the predominance of C3, C4, and CAM plants and of changes in temperature and precipitation. Taken together with other previously analyzed data from these localities, the evidence indicates a shift in the severity of glacial events that is mainly related to the hydrologic characteristics of the climate. This shift may have been caused by broad regional uplift that may have been instrumental in shifting global climate cycles from the 41,000-yr Matuyama cycles to the Brunhes 100,000-yr-dominated cycles.

Abstract:

Longitudinal in vivo imaging studies characterizing subarachnoid hemorrhage (SAH)-induced large artery vasospasm (LAV) in mice are lacking. We developed a SAH-scoring system to assess SAH severity in mice using micro CT and longitudinally analysed LAV by intravenous digital subtraction angiography (i.v. DSA). Thirty female C57Bl/6J-mice (7 sham, 23 SAH) were implanted with central venous ports for repetitive contrast agent administration. SAH was induced by filament perforation. LAV was assessed up to 14 days after induction of SAH by i.v. DSA. SAH-score and neuroscore showed a highly significant positive correlation (rsp = 0.803, p < 0.001). SAH-score and survival showed a negative significant correlation (rsp = −0.71, p < 0.001). LAV peaked between days 3–5 and normalized on days 7–15. Most severe LAV was observed in the internal carotid (Δmax = 30.5%, p < 0.001), anterior cerebral (Δmax = 21.2%, p = 0.014), middle cerebral (Δmax = 28.16%, p < 0.001) and basilar artery (Δmax = 23.49%, p < 0.001). Cerebral perfusion on day 5 correlated negatively with survival time (rPe = −0.54, p = 0.04). Arterial diameter of the left MCA correlated negatively with cerebral perfusion on day 3 (rPe = −0.72, p = 0.005). In addition, pseudoaneurysms arising from the filament perforation site were visualized in three mice using i.v. DSA. Thus, micro-CT and DSA are valuable tools to assess SAH severity and to longitudinally monitor LAV in living mice.

Abstract Objectives To identify SAM and MAM children using WHZ and MUAC. To derive age-appropriate MUAC cut offs for identifying SAM and MAM in children. Assess the sensitivity of MUAC for screening of SAM and MAM in children 7–36 mos. Arriving at age specific MUAC cut offs for identification of acute malnutrition can facilitate early identification of SAM to bring about reduction in under nutrition related morbidity and mortality and promote effective community based management. Methods The study was conducted in Antela and Piplod villages. Limkheda-I was included in the study because of the lesser amount of children found in the above mentioned villages. The prevalence of various forms of undernutrition- stunting, wasting and underweight was found using WHZ, WAZ, HAZ and MUAC. The Prevalence of MAM by MUAC was mapped using the cut-off between the range of 11.5 cm to 12.5 cm and SAM using the cut-off of <11.5 cm. Prevalence of MAM and SAM was mapped by WHZ. The age appropriate MUAC cut offs for identifying SAM and assessing Sensitivity and Specificity of MUAC vis-à-vis the gold standard WHZ were arrived at. Results The highest prevalence of undernutrition was in the form of stunting in the children, followed by underweight and wasting. Correlation between various anthropometric indices and factors likely to affect the same were established and WAZ and WHZ (0.62) were found to be highly correlated. The correlation of present body weight was highest with MUAC indicating that a little change in child's weight would cause change in MUAC thus making it an appropriate indicator of acute malnutrition. Sensitivity and Specificity of various MUAC cut offs were arrived at and Youden index was calculated by plotting ROC curves. MUAC cut off of <11.1 cm had the highest Youden index and the optimal cut off for identifying SAM was <11.1 cm (sen. of 99.9%, sp. 99.7%). Conclusions MUAC is age dependent and therefore age specific MUAC cut offs need to be derived for early detection of SAM. A single cut-off is not adequate to detect SAM. A higher prevalence of stunting, wasting and underweight was seen in males and hence MUAC and WHZ is affected by gender in the present study. Funding Sources The study was funded was UGC DSA SAP III.

Abstract:

Seven sources of cotton representing a wide range of fiber properties were roller ginned, saw ginned, or saw ginned plus processed through tandem saw lint cleaners or through an aggressive carding-type cleaner (Cottonmaster1). Lint cleaner induced changes in fiber length and nep count were compared to fiber property measurements from roller ginned samples. Fiber length deterioration from saw ginning was negatively correlated with fiber strength. Fiber breakage in lint cleaning was positively correlated with fiber fineness. Resistance to fiber length damage in ginning was explained best by fiber strength and fineness, or an estimate of individual fiber strength. Initial and final nep level were related to fineness, nonlint content, and upper quartile length, but an increase in neps due to lint cleaning had no significant relationship to fiber properties.

Abstract:

O estado de São Paulo lidera a produção brasileira de água mineral. Devido ao seu complexo arcabouço hidrogeológico, composto por vários aquíferos sedimentares e fraturados, as águas minerais apresentam diferentes características hidrominerais. Assim, o principal objetivo foi avaliar o potencial hidromineral dos aquíferos paulistas, fundamentado pelo Código de Águas Minerais (CAM) e legislações internacionais correlatas, a partir de uma base de dados pública de laudos analíticos de 276 poços de águas subterrâneas da Companhia Ambiental do Estado de São Paulo (CETESB). Baseado nas concentrações de Sólidos Totais Dissolvidos (STD), observou-se que as águas subterrâneas possuem grau variável de mineralização, sendo as águas mais mineralizadas associadas aos sistemas aquíferos Serra Geral (SASG), Tubarão (SAT) e Bauru (SAB). Entretanto, apenas 8,7% das águas se enquadrariam como mínimo e baixo teores de STD pela legislação dos Estados Unidos. Similarmente, apenas duas amostras seriam enquadradas como muito pouco mineralizadas e 81,5% em pouco mineralizadas pela legislação europeia. Pelas classificações dispostas pelo CAM, as amostras foram caracterizadas pela temperatura, predominantemente, como frias e hipotermais, e uma pequena parcela como mesotermais e hipotermais. As águas mais frias prevaleceram no aquífero Cristalino (SAC), enquanto as águas de maiores temperaturas ocorreram no Guarani (SAG). Todo os aquíferos possuíram potencial hidromineral pela classificação química, pela concentração de flúor, seguido em ordem decrescente, pelo lítio no SAC, o vanádio no SASG, a alcalina bicarbonato no SAT, sulfato e selênio de forma mista no SAT e SASG.

Abstract:

The correlation of carbon isotope discrimination (△13C) with photosynthetic gas exchange and water use efficiency (WUE) in maize was investigated under low rainfall conditions with or without superabsorbent polymer (SAP). SAP (45 kg/ha) was mixed into the top 10 cm soil layer at sowing in lysimeters. Compared with the control plants not treated with SAP, the application of SAP increased net photosynthesis rate; stomatal conductance (gs); transpiration rate; chlorophyll content (Chl) and intrinsic water use efficiency at leaf level (WUEi), but decreased intercellular CO2 concentration (Ci) and leaf △13C. In plants supplied with SAP, leaf △13C was positively correlated with Ci (r = 0.864, P < 0.01) and negatively correlated with gs and WUEi (r = –0.860 and –0.626, P < 0.01, respectively). Leaf △13C was not correlated with Chl with or without SAP. Grain △13C significantly decreased by 12.4% and showed a significant negative correlation with grain WUE under SAP treatments (r = –0.670, P < 0.05). These results suggest that in the presence of SAP, maize leaf and grain △13C could be good indicators for evaluating maize WUE during periods of low rainfall.

Abstract:

Objective.Primary Sjögren’s syndrome (pSS) is an autoimmune disease in which the concentration of the acute-phase protein serum C-reactive protein (CRP) is low. We investigated whether levels of another acute-phase protein, serum amyloid A (SAA), are increased in patients with pSS and whether the immunological markers in patients with pSS are associated with variation in SAA levels.Methods.Serum SAA concentrations were measured by ELISA in 74 patients with pSS and in 56 control subjects with sicca symptoms.Results.Median SAA levels did not differ significantly between patients with pSS and subjects with sicca symptoms. In patients with pSS SAA concentrations correlated significantly with age, leukocyte count, CRP, interleukin 6, and C4. Unlike CRP, there was a significant inverse correlation between SAA and serum IgG levels and anti-SSA antibody titers, as well as a trend towards an inverse correlation between SAA and antinuclear antibody and rheumatoid factor titers.Conclusion.Our data imply that high SAA production could constitute a protective element in pSS: high SAA levels inhibit in particular various signs of B cell hyperreactivity, i.e., IgG and autoantibody production.

Abstract:

The dynamic spheroidization behavior of Ti2AlNb-based alloy with O lamellae during isothermal hot compression was investigated. The aspect ratio of lamellar O phase decreased at higher compression temperatures and lower strain rates, and more kinked or spherical O phases appeared. The results indicated that deformation conditions have a considerable effect on dynamic spheroidization behavior of Ti–22Al–25Nb alloy, and the correlation between spheroidization fraction and strain follows a Avrami-type sigmoid model. The strains for starting (εc) and finishing (εf) of the dynamic spheroidization determined with the nonlinear fit were 0.10–0.31 and 1.70–5.39, respectively. The εc was higher due to the consumption of compressed strains before the fracture of O lamellae. The kinetic rate of dynamic spheroidization is positively correlated with temperature rise and negatively correlated with strain rate. Dynamic spheroidization was achieved through a combination of shearing and diffusional process during different hot compression conditions.
