Abstract
Background
Obesity can affect postoperative outcomes of gastrectomy. Visceral fat area is superior to body mass index in predicting postoperative complications. However, visceral fat area measurement is time-consuming and is not optimum for clinical use. Meanwhile, trunk fat volume (TFV) can be easily measured via bioelectrical impedance analysis. Hence, this current study aimed to determine the association of trunk fat volume in predicting the occurrence of complications after gastrectomy.
Methods
We retrospectively reviewed patients who underwent curative gastrectomy for gastric cancer between November 2016 and November 2019. The trunk fat volume-to-the ideal amount (%TFV) ratio was obtained using InBody 770 before surgery. The patients were classified into the obese and nonobese groups according to %TFV (TFV-H group, ≥ 150 %; TFV-L group, < 150 %) and body mass index (BMI-H group, ≥ 25 kg/m2; BMI-L group, < 25 kg/m2). We compared the short-term postoperative outcomes (e.g., operative time, blood loss volume, number of resected lymph nodes, and duration of hospital stay) between the obese and nonobese patients. Risk factors for complications were assessed using logistic regression analysis.
Results
In total, 232 patients were included in this study. The TFV-H and BMI-H groups had a significantly longer operative time than the TFV-L (p = 0.022) and BMI-L groups (p = 0.006). Moreover, the TFV-H group had a significantly higher complication rate (p = 0.004) and a lower number of resected lymph nodes (p < 0.001) than the TFV-L group. In univariate analysis, %TFV ≥ 150, total or proximal gastrectomy, and open gastrectomy were found to be potentially associated with higher complication rates with p values < 0.1. Meanwhile, multivariate analysis revealed that %TFV ≥ 150 (OR: 2.73; 95%CI: 1.37–5.46; p = 0.005) and total or proximal gastrectomy (OR: 3.57; 95%CI: 1.79–7.12; p < 0.001) were independently correlated with postoperative morbidity.
Conclusions
%TFV independently affected postoperative complications. Hence, it may be a useful parameter for the evaluation of obesity and a predictor of short-term surgical outcomes after gastrectomy.

Published: February 2021

Abstract
The leakage current is prime concern in the modern portable battery operated device. However, various techniques are presented and performance is evaluated using MOSFET and FinFET devices. To further reduce leakage current for improved battery backup in portable devices, new devicesnamely Carbon Nano Tube Field Effect transistors (CNTFETs) can be used for design of different digital circuits. In this paper, subthreshold leakage power of dual chiral CNTFET based domino circuit is investigated and also the results are compared with single chiral CNTFET domino circuits. For better performance, threshold voltage of CNTFET in critical path is varied by changing the diameter or chirality of carbon nanotube. Subthreshold leakage power saving in dual chiral standard and LECTOR based domino circuits for OR2, OR4, OR8 & OR16 for low temperature (25°C) & low input ranges from 90.36- 95.96% and from 91.97-97.3%; for low temperature & high input ranges from 90.66-95.23% and from 92.85-96.39%; for high temperature (110°C) & low input ranges from 89.24- 99.73% and from 27.5-99.83%; for high temperature & high input ranges from 89.65-97.86% and from 91.85-99.76% when compared with single chiral standard and LECTOR based domino circuits respectively.

Published: February 2021

Abstract
The Langmuir monolayer is commonly described at interfaces for an insoluble homogenous single molecular layer. Langmuir monolayers have demonstrated various issues regarding soft matters and complex fluids by forming ideal uniform two-dimensional structures over the air-water interface. This monolayer has advantages for evaluating physicochemical properties at interfaces and, for the insoluble molecules, can be applied simultaneously to the different interaction occurrences at interfaces. For this experiment, monoolein lipid was used as a spreading solvent to create a Langmuir monolayer, and five different types of salt sub-phases were applied for the physicochemical properties’ interaction studies. On the air-water interface, the surface properties of monoolein lipids were investigated for interfacial phase behaviors, using the Wilhelmy plate pressure sensor technique compression isotherm (π-A). Data and analysis were also contributed to the correspondent, precise verification of physical state behavior with the surface pressure measurements on the interfaces through the compressibility modulus and the elasticity modulus parameters on the surface. In the experiments, the interfacial activity of the monoolein lipids was found to be stable on the aqueous sub-phase, while the area per molecule over the interface did not have much impact as a sub-phase with a change in salts. The repeatability and reproducibility of tests were affirmed by the difference in the Langmuir monolayer’s particular phase transition orientation behavior and the stability of colloidal lipid dispersion. However, Langmuir monolayer formation contributes to several special groups being restructured and is found to be a more remarkable natural process for their attractive organic dynamic structural properties over the interface, but the interfacial molecular dynamics have proven to be difficult to calculate.

Published: February 2021

Abstract
Aging is an ultimate reality that everyone has to face. D-galactose (D-gal) has been used extensively to develop aging model. Trace elements such as selenium (Sel) have been used as a potential antioxidant for neuro-protection. The present work aims to develop therapeutic agents such as Sel for the treatment of aging-induced neurological ailments such as anxiety, depression, and memory impairment. For this purpose, mice were treated with D-gal at a dose of 300 mg/ml/kg and various doses of Sel (0.175 and 0.35mg/ml/kg) for 28 days. Behavioural tests were monitored after treatment days. After the behavioural assessment mice were decapitated and their brains were collected. Hippocampi were removed from the brain for biochemical and neurochemical analysis. The present findings of behavioural analysis showed that D-gal induced anxiety and depression-like symptoms were inhibited by both doses of Sel. D-gal induced memory alteration was also prevented by repeated doses (0.175 and 0.35mg/ml/kg) of Sel. Biochemical analysis showed that D-gal induced increase of oxidative stress marker and decrease of antioxidant enzymes in the hippocampus was prevented by Sel administration. An increase in the activity of acetylcholinesterase was also diminished by Sel. The neurochemical assessment showed that D-gal induced increased serotonin metabolism and decreased acetylcholine levels in the hippocampus were restored by repeated treatment of Sel. It is concluded that D-gal induced dysfunction in mice hippocampus caused anxiety, depression, memory impairment, oxidative stress that were mitigated by Sel via its antioxidant potential and modulating capability of serotonergic and cholinergic functions.

Abstract
BACKGROUND: Hepatocellular carcinoma (HCC) development among hepatitis B surface antigen (HBsAg) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBsAg-positive male adults.METHODS: HBsAg-positive, 35-69 years males (N=6 153) were recruited from a multi-center population-based liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using B-ultrasonography and α-fetoprotein (AFP). We used logistic regression models to determine potential risk factors, built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.RESULTS: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant’s Age, Blood levels of GGT (γ-glutamyl-transpeptidase), Counts of platelets, white cells, Concentration of DCP (des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.89-0.93), larger than existing models. At 1.5 points of risk-score, 26.10% of the participants in training, 14.94% in validation were recognized at-low-risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training, 33.68% in validation were recognized at-low-risk with 99.06% and 97.78% of sensitivity. At 4.5 points, only 20.86% of training, 23.73% of validation were recognized at-high-risk, with positive prediction value of 22.85% and 12.35% respectively.DISCUSSION: Male-ABCD algorithm identified individual’s risk for HCC occurrence within short-term for their HCC precision surveillance.

Abstract
Ceramic/polymer nanocomposites have shown great potential in high energy storage density capacitors for pulsed power applications. However, due to the difference in surface energy between inorganic fillers and polymers, the discharge energy density and efficiency of nanocomposites are limited. In this article, the BaTiO3 (BT) nanowires (nws) modified with dopamine (Dopa) was introduced into aromatic polythiourea (ArPTU) polymer matrix as composite for high performance dielectrics. This is a new path about the introduction of a high dielectric constant ceramic into high dipole moment linear polymers (HDMLP), which produces the polymer composite with high energy storage density and high discharge efficiency. The composite ArPTU/BT nws shows an energy density of 7.5 Jcm-3 and high efficiency more than 90 % is obtained under an electric field of 250 MVm-1. It also has been found that the modification of BT nws with the dopamine reduces the dielectric loss of composite effectively due to the good synergistic effective between ArPTU and BT nws, and high stability of composite for energy storage is also achieved. This work provides an effective solution for achieving high energy storage density and high discharge efficiency in polymer dielectrics for practical capacitor applications.

Published: February 2021

Abstract
Background: Blood coagulation has been associated with ovulation and female infertility. In this study, the expression of the tissue factor system was examined during ovulation in immature rats; the correlation between tissue factor and ovarian hyperstimulation syndrome (OHSS) was evaluated both in rats and human follicular fluids. Methods: Ovaries were obtained at various times after human chorionic gonadotropin (hCG) injection to investigate the expression of tissue factor system. Expression levels of ovarian tissue factor, tissue factor pathway inhibitor (Tfpi)-1 and Tfpi-2 genes and proteins were determined by real-time quantitative polymerase chain reaction (qPCR), and Western blot and immunofluorescence analyses, respectively. Expression levels of tissue factor system were also investigated in ovaries of OHSS-induced rats and in follicular fluid of infertile women.Results: The expression of tissue factor in the preovulatory follicles was stimulated by hCG, reaching a maximum at 6 h. Tissue factor was expressed in the oocytes and the preovulatory follicles. Tfpi-2 mRNA levels were mainly increased by hCG in the granulosa cells whereas the mRNA levels of Tfpi-1 were decreased by hCG. Human CG-stimulated tissue factor expression was inhibited by the progesterone receptor antagonist. The increase in Tfpi-2 expression by hCG was decreased by the proliferator-activated receptor γ (PPARγ) antagonist. Decreased expression of the tissue factor was detected in OHSS-induced rats. Interestingly, the tissue factor concentrations in the follicular fluids of women undergoing in vitro fertilization were correlated with pregnancy but not with OHSS. Conclusions: Collectively, the results indicate that tissue factor and Tfpi-2 expression is stimulated during the ovulatory process in rats; moreover, a correlation exists between the levels of tissue factor and OHSS in rats but not in humans.

Abstract
Objectives Progressive weakness of respiratory muscle is common to patients with amyotrophic lateral sclerosis, which leads to respiratory failure, even death. The evaluation of respiratory muscle is essential to evaluate the severity during the progression of the disease and choose appropriate interventions. This study aimed to evaluate the respiratory muscles change of the patients with amyotrophic lateral sclerosis by regular chest computed tomography. Methods The cross-sectional area of respiratory muscles in amyotrophic lateral sclerosis patients was retrospectively reviewed. The severity of the disease was determined by the value of the amyotrophic lateral sclerosis function score scale. A healthy control group was selected with well-matched to the amyotrophic lateral sclerosis patients. Results Compared with the healthy control group, the cross-sectional area of the diaphragm muscle was lower in amyotrophic lateral sclerosis patients. The reduced cross-sectional area of respiratory muscles has a positive correlation with a lower amyotrophic lateral sclerosis function score. Patients with amyotrophic lateral sclerosis further showed a significant reduction in the cross-sectional area of respiratory muscles after 6-8 months.Conclusions The single-slice axial computed tomography is a fast and reliable method to quantitatively assess the cross-sectional area of respiratory muscles, especially diaphragm muscle, in disease progression.

Published: February 2021

Abstract
Nothofagus alessandrii (Nothofagaceae) is one of the most endangered trees from Chile. Despite its conservation status, few molecular markers are available to study its population genetic, connectivity and to assist reproduction programs. Novel polymorphic microsatellites from the genome of N. alessandrii were isolated and characterized using high-through sequencing. A total of 30 primer pairs were synthesized and 18 microsatellites were amplified correctly. Polymorphism and genetic diversity was evaluated in 58 individuals from three populations of N. alessandrii. Sixteen of them were polymorphic and the number of alleles in the pooled sample ranged from 2 to 14, the mean number of alleles was 4.81. The mean values of observed heterozigosity (HO) and excepted heterozygosity (HE) of the Chanco population were 0.392 and 0.383. The mean values of HO and HE in the population of Empedrado (0.397 and 0.360, respectively) and Fundo el Desprecio (0.397 and 0.395, respectively) were similar. Linkage disequilibrium was found in a few pairs of loci suggesting that most of the markers can be considered as independent. Significant deviations from Hardy- Weinberg equilibrium (P < 0.05) were found in several loci probably due to low sampling size. Transferability to the congeneric N. pumilio was successful in only four out of the sixteen polymorphic markers. The microsatellite markers developed in this study will be useful to study the genetic diversity and structure and to develop integrated managements plans for the conservation on this endangered species.

Abstract
Background: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension statement for network meta-analysis (NMA) published in 2015 promotes comprehensive reporting in published systematic reviews with NMA. PRISMA-NMA includes 32 items in total: 27 core items as indicated in the core 2009 PRISMA Statement and five additional items specific to the reporting of NMAs. Although reporting of NMAs is improving, it is unclear whether the PRISMA-NMA statement has accelerated this improvement. Our aim was to investigate the impact of PRISMA-NMA statement and highlight key items that require further attention and improvement.Methods: We updated our previous collection of NMAs with articles published between April 2015 and July 2018. We assessed the completeness of reporting for each NMA, including main manuscript and online supplements, using the PRISMA-NMA checklist. We also prepared a modified version of the PRISMA-NMA checklist with 49 items to evaluate separately at a more granular level all multiple-content items. We compared average reporting scores of articles published before and after 2015.Results: In the 1,144 included NMAs the mean modified PRISMA-NMA score was 32.1 (95% CI 31.8-32.4). For one-year increase the mean modified score increased by 0.96 (95% CI 0.32 to 1.59) for 389 NMAs published until 2015 and by 0.53 (95% CI 0.02 to 1.04) for 755 NMAs published after 2015. The mean modified PRISMA-NMA score for NMAs published after 2015 was higher by 0.81 (95% CI 0.23 to 1.39) compared to before 2015 when adjusting for journal impact factor, type of review, funding, and treatment category. Description of summary effect sizes to be used, presentation of individual study data, sources of funding for the systematic review and role of funders dropped in frequency after 2015 by 6-16%.Conclusions: NMAs published after 2015 more frequently reported the five items associated with NMA compared to those published before 2015. However, improvement in reporting after 2015 is compatible with that observed on a yearly basis before 2015 and hence it could not be attributed solely to the publication of PRISMA-NMA statement.

Abstract
BackgroundThe aim was to verify the effect of non-periodized and linear periodized combined (aerobic more resistance) exercise training on insulin resistance markers in adults with obesity. MethodsWas conducted a blinded randomized controlled trial with three groups of individuals with obesity (BMI, 30–39.9kg/m²): control group (CG, n=23), non-periodized group (NG, n=23), and linear periodized group (PG, n=23). The NG and PG performed aerobic and resistance exercises in the same session in aerobic-resistance order for 16 weeks. Both intervention groups trained three sessions weekly, with total duration of 60 minutes each. The aerobic training of the NG had duration of 30 min always between 50%–59% of the reserve heart rate (HRres), while resistance part was compost of 6 exercise, performed always in 2×10–12 maximum repetitions (RM). The PG progressed the aerobic and resistance training from 40%–49% to 60%–69% (HRres) and from 2×12–14 to 2×8–10 RM, respectively, along intervention period. The evaluated indicators of insulin resistance included fasting glucose, fasting insulin, and homeostasis model assessment-estimated insulin resistance (HOMA-IR) collected pre and post intervention. The analyses to verify the exercise training effect were performed using generalized estimating equations. ResultsAfter 16 weeks of training, per protocol analysis (n=39) showed significant reductions in HOMA-IR only in the training groups (NG: ∆=-1.6, PG: ∆=-0.6; p=0.094). Intention-to-treat analysis demonstrated significant reductions in fasting insulin levels (NG: ∆=-1.4, PG: ∆=-1.0; p=0.004) and HOMA-IR (NG: ∆=-5.5, PG: ∆=-3.8; p=0.002). Conclusion﻿Periodized and non-periodized combined exercise training reduces similarly insulin resistance markers in adults with obesity.
