Conduction Band and Defect Engineering for the Prominent Visible-Light Responsive Photocatalysts.

Controlling trap depth is crucial to improve photocatalytic activity, but designing such crystal structures has been challenging. In this study, we discovered that in 2D materials like BiOCl and Bi4NbO8Cl, composed of interleaved [Bi2O2]2+ and Cl- slabs, the trap depth can be controlled by manipulating the slab stacking structure. In BiOCl, oxygen vacancies (VO) create deep electron traps, while chlorine vacancies (VCl) produce shallow traps.

Associations of sleep duration and weekend catch up sleep with cancer risk among US adults in the Cancer Prevention Study-3 cohort.

Objective: Our objective was to investigate the associations of sleep duration and weekend catch-up sleep with cancer risk among US adults in the Cancer Prevention Study-3.

Methods: Cancer Prevention Study-3 is a prospective cohort of approximately 250,000 US adults aged 30-65years. At baseline (2006-2013), participants were asked to report their average daily sleep duration over the past year for weekdays and weekends separately.

Effects of early antihypertensive treatment on cognitive function in patients with acute ischemic stroke with different neurofilament light chain levels.

Background: It is unclear whether the extent of neuroaxonal damage, as measured by circulating levels of neurofilament light chain (NfL), would modify the effects of early antihypertensive therapy on cognitive performance following stroke. This study aimed to investigate the effects of early blood pressure reduction on the risk of post-stroke cognitive impairment (PSCI) among patients with different plasma NfL levels.

Methods: A total of 622 eligible patients from a pre-planned ancillary study of CATIS (China Antihypertensive Trial in Acute Ischemic Stroke) were included in this study.

eEF2K alleviates doxorubicin-induced cardiotoxicity by inhibiting GSK3β and improving autophagy dysfunction.

Doxorubicin-induced cardiotoxicity (DIC) poses a threat to the health and prognosis of cancer patients. It is important to find a safe and effective method for the prevention and treatment of DIC. eEF2K, which is a highly conserved α-kinase, is thought to be a therapeutic target for several human diseases.

Circadian rhythm mechanisms underlying convergent adaptation of unihemispheric slow-wave sleep in marine mammals.

Marine mammals have evolved unihemispheric slow wave sleep (USWS), a unique state during which one cerebral hemisphere sleeps while the other remains awake, to mitigate the fundamental conflict between sleep and wakefulness. However, the underlying mechanisms remain largely unclear. Here, we use a comparative phylogenetic approach to analyze genes associated with light-dependent circadian mechanisms, aiming to reconstruct the evolution of the circadian rhythm pathway in mammals and to identify adaptively changed components likely to have contributed to the development of USWS.
