Development of Potent and Selective Inhibitors of Methylenetetrahydrofolate Dehydrogenase 2 for Targeting Acute Myeloid Leukemia: SAR, Structural Insights, and Biological Characterization.

Methylenetetrahydrofolate dehydrogenase/cyclohydrolase 2 (MTHFD2), a pivotal mitochondrial enzyme in one-carbon metabolism, is significantly upregulated in various cancers but minimally expressed in normal proliferating cells. In contrast, MTHFD1, which performs similar functions, is predominantly expressed in normal cells. Therefore, targeting MTHFD2 with selective inhibitors holds promise for a broader therapeutic window with reduced toxicity and fewer side effects.

Evodiamine exerts anti-cancer activity including growth inhibition, cell cycle arrest, and apoptosis induction in human follicular thyroid cancers.

Thyroid cancer (TC) is one of the most prevalent endocrine malignancy with a steadily increasing incidence globally. Although standard treatments like thyroidectomy and radioiodine therapy effectively manage most cases of differentiated thyroid cancers (DTC), certain recurrent cases or those involving poorly differentiated thyroid cancers (PDTC) demand more specialized interventions. Follicular thyroid cancer (FTC) is the second most common type of DTC, and frequently metastasizes through the bloodstream to distant sites such as bones and lungs which is a leading cause of metastatic and recurrent DTC and significantly affects survival.

Electrospun gelatin/hyaluronic acid nanofibers as a platform for uric acid delivery to neural tissue.

Uric acid (UA) is an antioxidant that has been reported to be a neuroprotective compound for injuries and diseases, and specifically, diseases of the central nervous system. However, uric acid is highly insoluble in aqueous solutions, and high levels in the serum lead to gout, which limits its use in humans. Here, we develop a novel drug delivery platform that will release uric acid in a sustained manner for application to neural tissue.

The efficacy of early office hysteroscopy in preventing intrauterine adhesions after abortion: a randomized controlled trial.

Background: Intrauterine adhesions (IUA) are a challenging clinical problem in reproductive infertility. The most common causes are intrauterine surgery and abortions. We aimed to investigate whether early second-look office hysteroscopy can prevent IUA.

Social determinants of health that impact the time to diagnosis and treatment of infertility in Taiwan.

Background/purpose: Taiwan is one of the countries with the lowest birth rate in the world. We investigated factors associated with the time to diagnosis and treatment of infertility in Taiwan.

Methods: The study was conducted through an online questionnaire in December 2021.
