Pollen germination and pollen tube (PT) growth are extremely sensitive to high temperatures. During heat stress (HS), global translation shuts down and favors the maintenance of the essential cellular proteome for cell viability and protection against protein misfolding. Here, we demonstrate that under normal conditions, the Arabidopsis (Arabidopsis thaliana) eukaryotic translation initiation factor subunit eif3m1/eif3m2 double mutant exhibits poor pollen germination, loss of PT integrity and an increased rate of aborted seeds.

Ultraportable (UP) X-ray devices are ideal to use in community-based settings, particularly for chest X-ray (CXR) screening of tuberculosis (TB). Unfortunately, there is insufficient guidance on the radiation safety of these devices. This study aims to determine the radiation dose by UP X-ray devices to both the public and radiographers compared to international dose limits.

Complex biological systems undergo sudden transitions in their state, which are often preceded by a critical slowing down of dynamics. This results in longer recovery times as systems approach transitions, quantified as an increase in measures such as the autocorrelation and variance. In this study, we analysed paediatric patients in intensive care for whom mechanical ventilation was discontinued through removal of the endotracheal tube (extubation).

Many cell types are involved in the regulation of cutaneous wound healing in diabetes. Clarifying the mechanism of cell-cell interactions is important for identifying therapeutic targets for diabetic cutaneous ulcers. The function of vascular endothelial cells in the cutaneous microenvironment is critical, and a decrease in their biological function leads directly to refractory wound healing.

Purpose: Ocular neovascularization is a major cause of blindness. Although fibroblast growth factor-2 (FGF2) has been implicated in the pathophysiology of angiogenesis, the underlying mechanisms remain incompletely understood. The purpose of this study was to investigate the role of FGF2 in retinal neovascularization and elucidate its underlying mechanisms.
