Changes in physical activity levels and increases screen time across different cohorts may affect young children’s motor skill development (MSD). This study examined cohort differences MSD China. Four-year-olds living Shanghai Guizhou province were assessed, individual sessions, 2013 (n = 230) 2017 446). Controlling for age, parental education, gender, height, weight, overall development, score...

The endolithic environment is a ubiquitous habitat for microorganisms and a critical interface between biology and geology. In this study, a culture-based method and the phylogenetic analysis based on 16S rRNA and internal transcribed spacer (ITS) sequences were used to investigate the diversity of endolithic bacteria and fungi in two main types of carbonate rocks (namely dolomite and limestone...

This study aimed to investigate polymorphisms of the eighth exon in the GFI1B gene among three indigenous Chinese goat breeds (QianBei Ma goats, GuiZhou white goats, and GuiZhou black goats). Furthermore, association analysis was conducted between these polymorphisms and growth traits. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), direct DNA sequencing, and PCR-r...

After early outbreaks in North America in April 2009, the pandemic influenza A (H1N1) virus spread rapidly around the world, and even some patients developed certain severe complications. We reported one case of hemophagocytic lymphohistiocytosis (HLH) induced by severe pandemic influenza A (H1N1) virus infection. A 17-year-old girl had acute onset of fever, dry cough, rhinorrhea, and sore thro...

BACKGROUND Because metallothionein (MT) is a metal-binding protein that protects against metal intoxication, it could be a biomarker for individual sensitivity to metal toxicity. OBJECTIVE We assessed the use of bloodborne MT transcript as a reflection of tissue MT levels and examined the potential role of MT in arsenic toxicity in an environmentally exposed human population. METHOD Rodents...

Though the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) was introduced into China more than 60 years ago, the genetic diversity and structure of this exotic insect pest and virus vector have not been studied. To investigate the population genetic characteristics of this invasive species and to identify potential invasion routes, the genetic diversity and po...

This study aimed to describe a new specimen of cavefish collected from a karst cave in the Daqikong area of Libo County, Guizhou. Twenty-six cavefish specimens were collected and identified as a new species of Balitoridae: Nemacheilinae, and named Oreonectes daqikongensissp. n. A genetic analysis was performed and showed that its genetic distances from Oreonectes shuilongensis and Oreonectes pl...
