Neuromuscular disorders are mostly rare diseases with autosomal dominant, recessive, or X-linked inheritance. Interestingly, among patients carrying the same mutations, a range of phenotypic severity is reported. This phenotypic variability in neuromuscular disorders is still not fully understood. This review will focus on genetic modifiers and will briefly describe metabolic pathways, in which they are involved. Genetic modifiers are variants in the same or other genes that modulate the phenotype. Proteins encoded by genetic modifiers in neuromuscular diseases are taking part in different metabolic processes, most commonly in inflammation, growth and regeneration, endoplasmic reticulum metabolism, and cytoskeletal activities. Recent advances in omics technologies, development of computational algorithms, and establishing large international consortia intensified discovery sped up investigation of genetic modifiers. As more individuals affected by neuromuscular disorders are tested, it is often suggested that classic models of genetic causation cannot explain phenotypic variability. There is a growing interest in their discovery and identifying shared metabolic pathways can contribute to design targeted therapies. We provide an update on variants acting as genetic modifiers in neuromuscular disorders and strategies used for their discovery.

Mechanical heart valves (MHVs) are widely used to replace diseased heart valves, but it may suffer from cavitation due to the rapid closing velocity of the leaflets, resulting in the damage of red blood cells and platelets. The aim of this study is to apply computational fluid dynamics (CFD) method to investigate the cavitation in bileaflets mechanical heart valves (BMHVs) and discuss the effects of the conduit and leaflet geometries on cavitation intensity.

Firstly, CFD method together with moving-grid technology were applied and validated by comparing with experimental results obtained from other literature. Then the leaflets movement and the flow rate of BMHVs with different conduit geometries and leaflet geometries are compared. At last, the duration time of the saturated vapor pressure and the closing velocity of leaflets at the instant of valve closure were used to represent the cavitation intensity.

Larger closing velocity of leaflets at the instant of valve closure means higher cavitation intensity. For BMHVs with different conduit geometries, the conduit with Valsalva sinuses has the maximum cavitation intensity and the straight conduit has the minimum cavitation intensity, but the leaflets cannot reach the fully opened state in a straight conduit. For BMHVs with different leaflet geometries, in order to minimize the cavitation intensity, the leaflets are better to have a large thickness and a small rotational radius.

CFD method is a promising method to deal with cavitation in BMHVs, and the closing velocity of leaflets has the same trend with the cavitation intensity. By using CFD method, the effects of the conduit geometry and the leaflet geometry on cavitaion in BMHVs are found out.

To examine the associations of colorectal cancer (CRC) screening with stages of weight control among Korean Americans (KAs) using the transtheoretical model and provide implications for their weight control practice.

A quantitative, cross-sectional survey was employed to collect data on current weight control behaviors and intentions, CRC screening history, previous cancer diagnosis, body mass index, number of chronic conditions, perceived health status, health insurance, and sociodemographics. Purposive sampling was implemented to recruit KA participants in the Atlanta metropolitan area in the USA from May 2015 to February 2016. A total of 433 KAs aged 50 to 75years completed a self-report survey questionnaire. Descriptive and bivariate analyses and multiple logistic regressions were performed using Stata Version 14/MP software.

Applying the stages of the transtheoretical model 53% were positioned in the first two stages (precontemplation and contemplation) of weight control with 47% being in the last alth disparities.A cross-sectional study was conducted to determine the associated factors of brucellosis in Colombia's preeminent dairy region declared in quarantine. A total of 656 samples were collected from cows ≥ 2-year-old from 40 herds. Samples were screened by the Rose Bengal Plate Test, and the Fluorescence Polarized Assay test and Competitive ELISA were used as confirmatory tests. A cow was classified as positive if the screening and both confirmatory tests were positive. A herd was classified as positive if at least one cow was seropositive. The factors associated to seropositivity were tested using a logistic regression model with explanatory variables regarding cattle management, zootechnical parameters, and sanitary practices. The seroprevalence at the animal level was 6.6% (43/656) and at herd level 27.5% (11/40). In the model, five variables explained the animal cases purchase or animal transfer between owner's farms (OR = 2.79, 95% CI 1.42, 5.49), history of abortion (OR = 4.22, 95% CI 1.91, 9.33), birth of weak calves (OR = 13.77, 95% CI 2.75, 68.91), use of a bull for mating (OR = 9.69, 95% CI 2.23, 42.18), and the vaccination in adulthood (OR = 3.03, 95% CI 1.04.8.78). In the model at the herd level, two variables explained the cases birth of weak calves (OR = 9.60, 95% CI 1.54, 59.76) and purchase or animal transfer between owner's farms (OR = 7.22, 95% CI 1.03, 50.62). These results justify the need for a quarantine declaration in the region and the implementation of epidemiological studies as a public health measures used to combat outbreak.We evaluated the effect of three different Bradyrhizobium strains inoculated in two soybean genotypes (R01-581F, drought-tolerant, and NA5858RR, drought-sensitive) submitted to drought in two trials conducted simultaneously under greenhouse. TG101348 The strains (SEMIA 587, SEMIA 5019 (both B. elkanii), and SEMIA 5080 (B. diazoefficiens)) were inoculated individually in each genotype and then submitted to water restriction (or kept well-watered, control) between 45 and 62 days after emergence. No deep changes in plant physiological variables were observed under the moderate water restriction imposed during the first 10 days. Nevertheless, photosynthesis and transpiration decreased after the severe water restriction imposed for further 7 days. Water restriction reduced growth (- 30%) and the number of nodules (- 47% and - 58% for R01-581F and NA5858RR, respectively) of both genotypes, with a negative effect on N-metabolism. The genotype R01-581F inoculated with SEMIA 5019 strain had higher photosynthetic rates compared with NA5858RR, regardless of the Bradyrhizobium strain.
