Elymus, the largest genus of the Triticeae Dumort, is a forage grass in the Qinghai-Tibetan Plateau, where the climate has gradually become increasingly dry in recent years. To understand the mechanisms of the response to drought stress in Elymus species, we first investigated physiological and biochemical responses to polyethylene glycol (PEG-6000) simulated drought stress in two Elymus species, Elymus nutans and Elymus sibiricus, and found that E. nutans was more tolerant to drought stress than E.

BACKGROUND This study aimed to conduct a clinical evaluation of four restorative materials for restoration of dental wedge-shaped defect (WSD) and their impacts on periodontal tissues. MATERIAL AND METHODS A total of 280 maxillary premolars with dental WSD were selected from 106 patients; the patient cases were divided into eight groups according to different combinations of restorative materials (flowable resin composites, Dyract compomers, glass ionomer cement (GIC), light-curing composite resin), and WSD positions (approaching gingival and subgingival positions). Gingival crevicular fluid (GCF) volume, levels of aspartate aminotransferase (AST), alkaline phosphatase (ALP), and interleukin-1β (IL-1β) in GCF were analyzed, while probing depth (PD), plaque index (PLI), and sulcus bleeding index (SBI) were also measured.

Article Synopsis
  • Near-infrared reflectance spectroscopy (NIRS) is a cost-effective, quick, eco-friendly, and non-invasive method used to analyze dietary components and animal products, which is crucial for optimizing animal nutrition.
  • Traditional calibration of NIRS for predicting dietary elements like crude protein relies on NIR spectra from feed, making it challenging for grazing animals, but feces can provide vital dietary information through a method called Fecal-NIRS (F. NIRS).
  • F. NIRS can evaluate not just diet composition and digestibility, but also additional factors like reproductive status, and shows promise as a fast alternative to traditional chemical analyses in both animal diets and manure, although improvements in accuracy are still needed, particularly in less researched

Siberian wildrye (Elymus sibiricus L.) is one of the predominant pasture species in Qinghai-Tibet plateau of China. It supplies a large number of fodders to domestic animals in spring and winter, and provides a large proportion of the summer and autumn grazing in these alpine regions.

Article Synopsis
  • The NOTCH4 gene plays a role in neuronal development and is linked to schizophrenia susceptibility, prompting research on its polymorphisms in a specific population.
  • In this study, researchers analyzed two polymorphisms (rs2071287 and rs204993) in a group of 443 schizophrenia patients and 628 healthy controls from the Han Chinese population.
  • Findings indicate that the rs204993 polymorphism significantly increases schizophrenia risk, particularly for individuals with the AA genotype, supporting previous studies and suggesting further research is needed.

Article Synopsis
  • Tetraspanin-18 (TSPAN18) is linked to calcium signaling that may contribute to dopamine-related neuron death, a potential factor in schizophrenia (SCZ).
  • A genome-wide association study identified TSPAN18 as a possible susceptibility gene for SCZ, prompting further analysis of seven SNPs in a study involving 443 SCZ patients and 628 controls of Han Chinese descent.
  • Results showed no significant associations between TSPAN18 genotypes and SCZ, suggesting it is not a major risk factor for schizophrenia within this population.

DNA sequencing analysis was used to investigate genetic alterations in the rpoB, katG, and inhA regulatory region and embB in 66 Mycobacterium tuberculosis isolates recovered from Central China. Of the 36 multidrug-resistant isolates, 33 (92%) had mutations in the amplified region of rpoB. The most frequent mutation (58%, 19/36) was S531L (TCG-->TTG).

Sixteen polymorphic primers screened from 100 random primers were selected to analyze the randomly amplified polymorphic DNA (RAPD) of 540 domesticated black goats (Capra hircas) from 9 different geographical populations in Sichuan Province of China. After the test, 170 entirely repeatable RAPD markers representing goat polymorphisms were obtained from the 16 polymorphic primers, the lengths of the markers ranging from 0.1 to 2.
