The transcription factor GhMYB4 represses lipid transfer and sucrose transporter genes and inhibits fiber cell elongation in cotton.

Cotton (Gossypium hirsutum) fiber is a highly elongated single cell with a thickened cell wall. MYB transcription factors are important regulators of plant cell elongation; however, the molecular mechanism involved in regulating fiber elongation remains to be explored. Here, we present evidence that the R2R3-MYB transcription factor GhMYB4 negatively regulates cotton fiber cell elongation by suppressing the expression of 2 crucial genes previously reported to affect fiber development: lipid transfer protein 4 (GhLTP4) and sucrose transporter 12 (GhSWEET12).

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters.

Introduction: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs).

Methods: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes.

Comparing the Fried frailty phenotype versus the Veterans Affairs frailty index among dialysis dependent patients.

Introduction: Frailty in dialysis patients is a modifiable disease state which can increase mortality if left untreated but remains underdiagnosed as frailty evaluations can be arduous or time consuming. We evaluate the agreement between a clinical frailty construct (Fried frailty phenotype, FFP) against and an electronic health record-based Veterans Affairs Frailty Index (VAFI) and their association with mortality.

Methods: A retrospective cohort analysis of 764 participants from the ACTIVE/ADIPOSE study was performed.

Research on the evolution and the driving forces of land use classification for production, living, and ecological space in China's Qilian Mountains Nature Reserve from 2000 to 2020.

With the rapid development of the economy, problems such as resource depletion, environmental degradation, and increasingly strained human-land relations have become increasingly prominent. The rational layout of the production, living, and ecological spaces is the basis for solving the contradiction between economic development and environmental protection. This paper analyzed the spatial distribution pattern and evolution characteristics of the Qilian Mountains Nature Reserve based on the theory of production, living, and ecological space.

A comparative study of environmental responsibility behavior in ecotourism from the perceptions of residents and tourists: A case of Qilian Mountains National Park in China.

The environmentally responsible behaviors of residents and tourists are great significance to the protection of natural resources and sustainable development of ecotourism. This paper takes China's Qilian Mountains National Park as the case place. By constructing a theoretical model of perceived value on environmentally responsible behavior and studying the relationship between residents' and tourists' perceived value, satisfaction and environmentally responsible behavior from both subject and object perspectives, the study shows that.
