Prevalence of vitamin B12 insufficiency during pregnancy and its effect on offspring birthweight: a systematic review and meta-analysis. [PDF]

open access: yes, 2016
Background: Vitamin B-12 and folate are micronutrients essential for normal embryogenesis. Vitamin B-12 insufficiency in pregnancy is high in certain parts of the world, such as India, and although this has been linked to low birth weight (LBW) in these ...

Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

open access: yesAdvanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,

Bottom‐Up Engineering of a Human Neuromuscular System for Modeling Activity‐Induced Remodeling, Metabolic Stress, and Endothelial‐Modulated Excitability

open access: yesAdvanced Materials, EarlyView.
Using a bottom‐up approach, we engineered a human neuromuscular microchip to investigate distinct adaptive responses to neural stimulation and metabolic stress. Further integration of endothelial cells revealed their critical role in modulating neuromuscular excitability, establishing a comprehensive neurovascular‐muscular model.

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...
