Molecular basis of vitamin K driven γ-carboxylation at membrane interface.

The γ-carboxylation of glutamate residues enables Ca-mediated membrane assembly of protein complexes that support broad physiological functions including hemostasis, calcium homeostasis, immune response, and endocrine regulation. Modulating γ-carboxylation level provides prevalent treatments for hemorrhagic and thromboembolic diseases. This unique posttranslational modification requires vitamin K hydroquinone (KH) to drive highly demanding reactions catalyzed by the membrane-integrated γ-carboxylase (VKGC).

Tempo-spatially modulated Mueller matrix imaging polarimeter based on modified Savart polariscopes.

Mueller matrix polarization measurement technique, as a non-invasive and label-free, provides comprehensive optical information on polarization-related and structural characteristics of the measured target. It has been widely applied in biomedical, agricultural, and industrial fields. However, the traditional time-division modulation Mueller matrix measurement method requires multiple measurements, which suffers from long measurement time and susceptibility to cumulative errors from moving parts.

The inhibition of anammox system under Cu stress and mechanisms of biochar-mediated recovery.

Copper (Cu)-containing wastewater has proven difficult to effectively treat using the anammox process. In this study, the nitrogen removal efficiency (NRE), sludge characteristics, microbial community and recovery mechanisms of biochar-mediated anammox under Cu stress were elucidated. At a Custress of 5 mg/L, a 73.

Construction of a potentially functional long noncoding RNA-microRNA-mRNA network in diabetic cardiomyopathy.

Background: Diabetic cardiomyopathy (DCM) is a severe complication among patients with Type 2 diabetes, significantly increasing heart failure risk and mortality. Despite various implicated mechanisms, effective DCM treatments remain elusive. This study aimed to construct a comprehensive competing endogenous RNA (ceRNA) network in DCM using bioinformatics analysis.

The effect of deep magnetic stimulation on the cardiac-brain axis post-sleep deprivation: a pilot study.

Introduction: Sleep deprivation (SD) significantly disrupts the homeostasis of the cardiac-brain axis, yet the neuromodulation effects of deep magnetic stimulation (DMS), a non-invasive and safe method, remain poorly understood.

Methods: Sixty healthy adult males were recruited for a 36-h SD study, they were assigned to the DMS group or the control group according to their individual willing. All individuals underwent heart sound measurements and functional magnetic resonance imaging scans at the experiment's onset and terminal points.
