Analysis of disease burden due to high body mass index in childhood asthma in China and the USA based on the Global Burden of Disease Study 2019

Plos.org 

by Chengyue Zhang, Qing Qu, Kaiyu Pan

Background

Currently, there is a growing concern about the disease burden of child asthma particularly due to high body mass index (BMI). The prevalence and disease burden of asthma differ between developing and developed countries, with implications on disease intervention. Therefore, we provide a comparative analysis of childhood asthma between China and the United States of America (USA).

Methods

Using the Global Burden of Disease (GBD) 2019 data... Читать дальше...

Multivariate analysis of food consumption profiles in crisis settings

Plos.org 

by Aleksandra Gorzycka-Sikora, Nancy Mock, Michelle Lacey

Preventing malnutrition is one of the primary objectives of many humanitarian agencies, and household surveys are regularly employed to monitor food insecurity caused by political, economic, or environmental crises. Consumption frequencies for standard food groups are often collected to characterize the depth of food insecurity in a community and measure the impact of food assistance programs, producing a vector of bounded, correlated counts for each household.

The relationship between health literacy and internet addiction among middle school students in Chongqing, China: A cross-sectional survey study

Plos.org 

by Yang Liu, Nannan Wu, Jie Yan, Junjie Yu, Liping Liao, Hong Wang

Background

Internet addiction has emerged as a major global concern as a potential adverse impact of internet exposure on adolescents. Internet addiction is associated with many demographic variables; however, there is a lack of consensus on its relationship with health literacy. Therefore, the aim of the present study was to assess the rates of internet addiction and health literacy level among middle school students (grades 7 to 12) in Chongqing... Читать дальше...



The role of self-efficacy in specific fears

Plos.org 

by Annalisa Lipp, Xiao Chi Zhang, Ekrem Dere, Armin Zlomuzica

Low self-efficacy for threatening stimuli and situations has been proposed as an important etiological factor in the development and maintenance of specific phobias. The present study examined the relationships between general self-efficacy (GSE), specific self-efficacy (SSE) and specific fears in a representative sample (n = 717). While GSE was associated with higher self-reported fear and avoidance, SSE (e.g. SSE in the presence... Читать дальше...

Atomistic simulation of protein evolution reveals sequence covariation and time-dependent fluctuations of site-specific substitution rates

Plos.org 

by Christoffer Norn, Ingemar André

Thermodynamic stability is a crucial fitness constraint in protein evolution and is a central factor in shaping the sequence landscapes of proteins. The correlation between stability and molecular fitness depends on the mechanism that relates the biophysical property with biological function. In the simplest case, stability and fitness are related by the amount of folded protein. However, when proteins are toxic in the unfolded state, the fitness function shifts... Читать дальше...

Topological descriptors of the parameter region of multistationarity: Deciding upon connectivity

Plos.org 

by Máté László Telek, Elisenda Feliu

Switch-like responses arising from bistability have been linked to cell signaling processes and memory. Revealing the shape and properties of the set of parameters that lead to bistability is necessary to understand the underlying biological mechanisms, but is a complex mathematical problem. We present an efficient approach to address a basic topological property of the parameter region of multistationary, namely whether it is connected. The connectivity... Читать дальше...

Feature-specific reactivations of past information shift current neural encoding thereby mediating serial bias behaviors

Plos.org 

by Huihui Zhang, Huan Luo

The regularities of the world render an intricate interplay between past and present. Even across independent trials, current-trial perception can be automatically shifted by preceding trials, namely the “serial bias.” Meanwhile, the neural implementation of the spontaneous shift of present by past that operates on multiple features remains unknown. In two auditory categorization experiments with human electrophysiological recordings, we demonstrate that serial bias... Читать дальше...

Elephant Rumblings: A’s running hard in Spring Training

MLB news roundup

Happy Friday, Athletics Nation!

New MLB rules could promote more aggressive baserunning and an increase in attempted stolen bases this season, and the A’s seem to be actively testing the waters with their running game in Spring Training.

Specifically, two new rules should make base stealing easier: first, the bases have grown from 15 to 18 inches squared. That may not seem like a lot, but I’ve seen countless plays decided by margins smaller than three inches. Читать дальше...
