Background: 7-Hydroxymethotrexate (7-OHMTX) is the main metabolite in plasma following high-dose MTX (HD-MTX), which may result in activity and toxicity of the MTX. Moreover, 7-OHMTX could produce crystalline-like deposits within the renal tubules under acidic conditions or induce renal inflammation, oxidative stress, and cell apoptosis through various signaling pathways, ultimately leading to kidney damage. The objectives of this study were thus to explore the exposure-safety relationship of two compounds and search the most reliable marker for predicting HDMTX nephrotoxicity.

This study offers new insights into the dual role of secretory phospholipase A2 (sPLA2) in lymphedema, highlighting its impact on lymphatic endothelial cell (LEC) functionality. Through transcriptomic analyses and co-culture experiments, we observed that sPLA2 has both protective and detrimental effects on human LECs (HLECs), mediated by macrophage activation. Our findings reveal that while low levels of sPLA2 promote LEC health, excessive sPLA2 leads to dysfunction, emphasizing the significance of the sPLA2/PLA2R axis and arachidonic acid metabolism (AA) in lymphedema pathology.

  • Humans combine social info and personal preferences when making risky choices, but it's unclear how this works if personal preferences are impaired.
  • The study focused on participants with specific brain lesions while they engaged in a gambling task, involving both solo and observed choices.
  • Results showed that those with lesions were less able to use standard risk calculations and instead relied more on conforming to others' choices, suggesting that social cues can drive decisions when personal risk assessment fails.

Background: Co-formulated dolutegravir and lamivudine (DTG/3TC) is recommended as the first-line antiretroviral therapy (ART); however, the data on the viral decay in seminal plasma (SP) and blood plasma (BP), as well as changes in inflammatory biomarkers in BP, remain limited among antiretroviral-naïve people with HIV (PWH) receiving DTG/3TC. A prospective observational cohort study was conducted to compare the impact of DTG/3TC vs. bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) on viral decay kinetics and changes in inflammatory biomarkers in antiretroviral-naïve PWH.

Article Synopsis
  • Memory consolidation during sleep depends on brain areas like the cortex, thalamus, and hippocampus, but how insomnia disrupts their metabolic patterns is still unclear.
  • This study investigates how insomnia affects metabolites related to memory consolidation, using both clinical research with human participants and experimental studies with rats.
  • Findings show that insomnia with mild cognitive impairment is associated with lower GABA levels, while sleep deprivation in rats worsens metabolic imbalances in the hippocampus, linking these changes to cognitive decline.

Reports of traditional Chinese medicine (TCM)-related liver injury have increased over recent years; however, identifying susceptibility-related components and biomarkers remains challenging due to the heterogeneous nature of TCM and idiosyncratic drug-induced liver injury (IDILI). (PF) and (EF), commonly found in TCM prescriptions, have been implicated in IDILI, but their constituents and underlying mechanisms are poorly understood. In this study, we identified bavachin (Bav) and icariin (Ica) as susceptibility components for IDILI in PF and EF using a TNF-α-mediated mouse model.

Osteoarthritis (OA) is recognized as a highly friction-related joint disease primarily associated with increased joint friction and inflammation due to pro-inflammatory M1-type macrophage infiltration in the articular cavity. Therefore, strategies to simultaneously increase lubrication and relieve inflammation to remodel the damaged articular microenvironment are of great significance for enhancing its treatment. Herein, a multifunctional core-brush nanoplatform composed of a ROS-scavenging polydopamine-coated SiO core and lubrication-enhancing zwitterionic poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) brush and loaded with the anti-inflammatory drug curcumin by a reactive oxygen species (ROS)-liable conjugation (named as SiO@PP-Cur) is rationally designed.

December 2024

Center for Reproductive Medicine, Department of Obstetrics and Gynecology, Beijing Key Laboratory of Reproductive Endocrinology and Assisted Reproductive Technology and Key Laboratory of Assisted Reproduction, Ministry of Education, Peking University Third Hospital, Beijing, 100191, China.

Purpose: Postovulatory aging (POA) of oocytes is clinically significant as it mirrors the degeneration observed in maternally aged oocytes, leading to substantial impairments in oocyte quality and the success rates of artificial reproductive technology (ART). The molecular alterations associated with POA, such as the degeneration of the first polar body, an increase in perivitelline space, reactive oxygen species (ROS) accumulation, energy depletion, and chromosomal and DNA damage, underscore the urgency of finding interventions to mitigate these effects. This study aims to identify whether nicotinamide riboside (NR) can prevent POA during the process of in vitro culture and raise the success rates of ART.
