Estrogen replacement therapy reverses spatial memory loss and pyramidal cell neurodegeneration in the prefrontal cortex of lead-exposed ovariectomized Wistar rats.

Background: Although menopause is a component of chronological aging, it may be induced by exposure to heavy metals like lead. Interestingly, lead exposure, just like the postmenopausal state, has been associated with spatial memory loss and neurodegeneration; however, the impact of hormone replacement therapy (HRT) on menopause and lead-induced spatial memory loss and neurodegeneration is yet to be reported.

Aim: The present study investigated the effect and associated mechanism of HRT on ovariectomized-driven menopausal state and lead exposure-induced spatial memory loss and neurodegeneration.

-based feed supplement protects against renal ischaemia/reperfusion injury via downregulation of Bax/caspase 3 signaling.

Introduction: Ischaemia/reperfusion (I/R) may lead to acute kidney injury via the induction of oxidative stress. On the other hand, Moringa oleifera has been reported to exert antioxidant activities. This study was designed to assess whether or not Moringa oleifera-based feed supplement could prevent I/R-induced renal injury.

Protein-protein interaction and interference of carcinogenesis by supramolecular modifications.

Protein-protein interactions (PPIs) are essential in normal biological processes, but they can become disrupted or imbalanced in cancer. Various technological advancements have led to an increase in the number of PPI inhibitors, which target hubs in cancer cell's protein networks. However, it remains difficult to develop PPI inhibitors with desired potency and specificity.

Identification of HER2 inhibitors from curcumin derivatives using combination of screening and molecular dynamics simulation.

Breast cancer remains a major world health challenge in women. Some Breast cancers are human epidermal growth factor receptor 2 (HER2) positive. Since this protein promotes the growth of cancer cells, it remains a therapeutic target for novel drugs.
