Advanced Science, EarlyView.Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Vaccination rates modulate the correlation between country latitude and covid-19 surge date arising this autumn 2021 [PDF]
arXiv, 2021 A clear linear correlation of covid-19 surge date with country latitude was observed last autumn 2020, but not with temperature, nor with humidity, pointing the seasonal vitamin D status decline as a contributor factor. Well vaccinated European countries are this autumn 2021 repeating explosive surges.

The prevalence of vitamin B12 deficiency in a random sample from the Australian population
, 2014 Objective: Vitamin B12 deficiency is common in older adults, and may increase the risk of cognitive impairment. The distribution of vitamin B12 insufficiency in younger age groups is less studied. This study aims to assess the prevalence of vitamin

Advanced Science, EarlyView.Conjugated microporous polymer membranes with narrowly distributed network pores are prepared by diffusion‐modulated electropolymerization. This approach precisely controls the monomer diffusion and coupling processes, regulating the crosslinking degree to prevent broad aggregate pores and microporous defects.

Advanced Science, EarlyView.A novel microporous polyimide (PI‐TB‐NDI) is designed for enhanced organic solvent nanofiltration. By incorporating o‐methyl groups into the Tröger's base (TB) unit to create molecular stents, the polymer's intrinsic free volume is effectively increased without the need for post‐treatment.

First principles investigations of electronic and magnetic properties of new rh.-B12N3 [PDF]
, 2020 Considering rhombohedral alpha-boron, rh-B12 as a matrix hosting interstitials particularly triatomic linear ones as in B12C3 better known as B4C, the subnitride B12N3 is proposed herein. The N3 triatomic linear alignment labeled N2-N1-N2 resembles that found in the ionic sodium azide NaN3 characterized by a very short d(N1-N2)= 1.16 A.

Effect of a Klamath algae product ("AFA-B12") on blood levels of vitamin B12 and homocysteine in vegan subjects: a pilot study [PDF]
, 2009 none8Vitamin B12 is a critical nutrient that is often inadequate in a plant-based (vegan) diet, thus the inclusion of a reliable vitamin B12 source in a vegan diet is recommended as essential.

Advanced Science, EarlyView.This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

B12C2N Interstitial Boron subcarbonitride with peculiar magnetic properties: First principles investigations [PDF]
arXiv, 2021 The subcarbides B12C3 and B13C2 known for their abrasive properties, can be structurally considered as carbon inserted rhombohedral alpha-B12 and expressed as B12{C-C-C} and B12(C-B-C). Using density functional theory DFT computations, the substitution of the central atom in the linear triatomic interstitials by N leads to an original new boron ...
