Nanoarchitectonics for Pentagon Defects in Carbon: Properties and Catalytic Role in Oxygen Reduction Reaction

open access: yesSmall Methods, EarlyView.
“Pentagon” in carbon framework is focused in this review, although hexagon is standard atomic frames in carbon materials. This review elucidates the fundamental principles governing pentagon‐related activity and offers perspectives on future directions for designing efficient oxygen reduction reaction catalysts based on carbon materials ...

Esophageal and Oropharyngeal Dysphagia: Clinical Recommendations From the United European Gastroenterology and European Society for Neurogastroenterology and Motility

open access: yesUnited European Gastroenterology Journal, EarlyView.
ABSTRACT Dysphagia is a prevalent symptom of the upper gastrointestinal tract causing health related consequences, impacting quality of life and is associated with global economic burden. Swallowing difficulties are classified into oropharyngeal dysphagia (OD) and esophageal dysphagia.

Detection of Transient Decomposition Products of CF3SO2F and C4F7N via OES Under Spark and Glow Discharges

open access: yesHigh Voltage, EarlyView.
ABSTRACT The optical emission spectra (OES) reflect the presence of excited states in the gaseous discharge, which are directly linked to the decomposition characteristics of insulating gases. In this study, a pin/rod–plate discharge reactor driven by either a high‐voltage direct current (DC) generator or a pulsed generator was developed to establish ...

Mechanistic Insights Into 5′‐tiRNA‐His‐GTG Mediated Activation of the JNK Pathway in Skin Photoaging

open access: yesAging Cell, EarlyView.
5′‐tiRNA‐His‐GTG expression level is upregulated in the photoaging cell model. 5′‐tiRNA‐His‐GTG negatively regulates the expression of NUP98, thereby activating the JNK signaling pathway to regulate cell senescence. ABSTRACT UV exposure leads to skin damage, thus inducing skin aging.

Patient‐Derived Cortical Organoids Reveal Senescence of Neural Progenitor Cells in Hutchinson‐Gilford Progeria Syndrome

open access: yesAging Cell, EarlyView.
HGPS patient‐derived cortical organoids exhibit progerin accumulation, nuclear abnormalities, and increased senescence in rosette structures, leading to impaired neuronal differentiation and altered gene expression. ABSTRACT Hutchinson‐Gilford progeria syndrome (HGPS) is a rare genetic disorder characterized by premature aging and primarily caused by ...

Semen cryopreservation and storage in liquid nitrogen: Impact on chromatin compaction

open access: yesAndrology, EarlyView.
Abstract Background Sperm cryopreservation is a consolidate option for long‐term male fertility preservation. The freezing/thawing procedure causes detrimental effects to spermatozoa, including damage to viability, motility, membrane composition, and DNA, whereas the effect on sperm chromatin compaction is less studied.
