The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Phosphorus availability alleviates chilling injury through modulation of phosphorus metabolism and cold-responsive gene expression in cucumber (Cucumis sativus L.) fruit

Plant Stress
Chilling stress is a major constraint in cucumber (Cucumis sativus L.) fruit, often causing chilling injury (CI) on the peel during low-temperature handling.

Chilling stress response in tobacco seedlings: insights from transcriptome, proteome, and phosphoproteome analyses

Frontiers in Plant Science
Tobacco (Nicotiana tabacum L.) is an important industrial crop, which is sensitive to chilling stress. Tobacco seedlings that have been subjected to chilling stress readily flower early, which seriously affects the yield and quality of their leaves ...

Hydrogen peroxide priming alleviates chilling stress in rice (Oryza sativa L.) by enhancing oxidant scavenging capacity

Fundamental and Applied Agriculture, 2019
Chilling is a substantial stressor for plants. In fact, some biochemical reactions involved in growth and development of plant are sensitive to temperature.

Special issue in honour of Prof. Reto J. Strasser - Photoinhibition of oxygen-evolving complex and photosystem II at chilling stress in the tropical tree species Dalbergia odorifera

Photosynthetica, 2020
Photosystem II is sensitive to chilling stress in tropical tree species. However, the underlying mechanism is not clear. In this study, we examined the effects of chilling and light stress on activities of PSII and oxygen-evolving complex (OEC), in order

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Nitric Oxide Mediates 5-Aminolevulinic Acid-Induced Antioxidant Defense in Leaves of Elymus nutans Griseb. Exposed to Chilling Stress. [PDF]

PLoS ONE, 2015
Nitric oxide (NO) and 5-aminolevulinic acid (ALA) are both extremely important signalling molecules employed by plants to control many aspects of physiology. In the present study, the role of NO in ALA-induced antioxidant defense in leaves of two sources
