Structural characterization of complex tannins from Euryale ferox fruit peels and their inhibitory mechanisms against tyrosinase activity and melanogenesis.

Tyrosinase is a rate-limiting enzyme for melanogenesis and abnormal melanin production can be controlled by utilizing tyrosinase inhibitory substances. To develop potent and safe inhibitors of tyrosinase, complex tannins a narrowly distributed plant polyphenols were prepared from the fruit peel of Euryale ferox (EPTs) and then structurally characterized, as well as investigated for their inhibitory effects and the involved mechanisms against tyrosinase activity and melanogenesis. The structures of EPTs were established to consist of 63.

Reduced GATA3 expression during breast cancer progression: A potential anchor for pulmonary metastatic deposition.

Estrogen receptor (ER) is a direct and reciprocal target gene for GATA3. Previous studies have shown that higher GATA3 expression in primary breast cancer (BC) is associated with a reduced probability of developing lung metastasis when compared to those with metastatic recurrence to other organs. Further, GATA3 downregulates several genes promoting BC lung metastasis and upregulates genes encoding known inhibitors of lung metastasis.

Achieving advanced hydrogen evolution under large current density using an amorphous/crystalline core-shell electrocatalyst of a-NiCoP/CoP.

Non-precious transition metal-based electrocatalysts with high activities are promising candidates for substituting Pt- or Ru-based electrocatalysts in hydrogen evolution. In this study, we propose core-shell engineering to combine the amorphous NiCoP and crystalline CoP (a-NiCoP/CoP@NF), which requires an ultra-low overpotential of only 26 mV to achieve the benchmark current density of 10 mA cm. Furthermore, it achieves an industrial-level hydrogen evolution current density of 500 mA cm with excellent stability.

Global Trends in the Incidence and Primary Causes of Femoral Fractures, Excluding Femoral Neck Fractures: A Global Epidemiological Study.

Purpose: Fractures pose a significant global health challenge, with varying incidence trends and causes across demographics and regions. This study aims to analyze global patterns in the incidence and primary causes of femoral shaft fractures.

Methods: Data from the Global Burden of Disease database were analyzed for femoral fractures (excluding femoral neck fractures) by age, gender, and socio-demographic index regions.

Construction of a cuproptosis-tricarboxylic acid cycle-associated lncRNA model to predict the prognosis of non-small cell lung cancer.

Background: In cuproptosis, excess copper ions induce cell death via fatty acylation in the tricarboxylic acid (TCA) cycle. However, the effects of cuproptosis-TCA-related long non-coding RNAs (lncRNAs) on the clinical prognosis of non-small cell lung cancer (NSCLC) and the associated tumor microenvironment remain unclear. The purpose of this study is to use cuproptosis-TCA related lncRNAs to predict the prognosis of NSCLC.
