Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

open access: yesAdvanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

Lithium Exposure Causes Trophoblast Cuproptosis by Upregulating FOXO1/STEAP4 Axis in Unexplained Miscarriage

open access: yesAdvanced Science, EarlyView.
Li exposure up‐regulates FOXO1 expression levels and thus promotes FOXO1‐mediated STEAP4 transcription, up‐regulating STEAP4 levels. Subsequently, STEAP4 up‐regulates intracellular Cu+ ion levels and causes cuproptosis, which further induces miscarriage.

Dopamine D1 Receptor Contributes to Glucocorticoid‐Associated Osteonecrosis of Femoral Head Protection Through the ATF3/CHOP Axis to Inhibit Osteoblastic Apoptosis

open access: yesAdvanced Science, EarlyView.
This work identifies a novel mechanism by which dopamine D1 receptor (DRD1) contributes to the pathogenesis of glucocorticoid (GC)‐associated osteonecrosis of the femoral head (ONFH) through the regulation of osteoblastic apoptosis, indicating that DRD1 serves as a critical mediator of the crosstalk between the nervous and skeletal systems.

Comments on : diet, physiology and ecology of fossil mammals as inferred from stable carbon and nitrogen isotope biogeochemistry: implications for Pleistocene bears [PDF]

open access: yes, 1997
A detailed study of isotopic relationships in European Pleistocene ursid teeth have been presented by Bocherens et al. (1994). We agree with the resu1ts and broad conclusions derived from the stable carbon isotope relationships.

Oscillating Magnetic Field Induced Bone Injury Repair by using Drug‐Free Micromotors

open access: yesAdvanced Science, EarlyView.
This work presents a payload‐free, minimally invasive approach for bone repair using magnetic hydrogel micromotors, which enhance bone regeneration via localized micromovement stimulation, achieving a twofold increase in new bone formation in vivo. Abstract Bone injury repair remains a significant clinical challenge due to the tissue's limited self ...
