This study tested the hypothesis that decreased estrogen levels accomplished by removing the ovaries affect the response to acutely administered alcohol in female mice. Sensitivity to alcohol was measured in ovariectomized, sham-operated, and non-surgical control C3H/HEN mice. Each animal received an IP injection of alcohol (3.0 or 4.0 g/kg). Core temperature, fall time, sleep time, and waking blood alcohol levels were the dependent variables. For each of these measures, alcohol sensitivity was found to be a function of the dose of alcohol administered, but not the surgical condition. Additionally, the stage of estrus in control animals was not found to be related to alcohol sensitivity.

Platelet aggregation and inflammation play a crucial role in atherothrombosis. Wine contains micro-constituents of proper quality and quantity that exert cardioprotective actions, partly through inhibiting platelet-activating factor (PAF), a potent inflammatory and thrombotic lipid mediator. However, wine cannot be consumed extensively due to the presence of ethanol.

Background/objectives: Basal cell skin cancer (BCSC) develops when skin cells proliferate uncontrollably. Sonidegib (SDB) is a therapeutic option for the treatment of BCSC by inhibiting hedgehog signaling. The problems with SDB's low solubility, poor bioavailability, resistance, poor targeting, and first-pass action make it less effective when taken orally.

This study presents the fabrication of a sustainable flexible humidity sensor utilizing chitosan derived from mealworm biomass as the primary sensing material. The chitosan-based humidity sensor was fabricated by casting chitosan and polyvinyl alcohol (PVA) films with interdigitated copper electrodes, forming a laminate composite suitable for real-time, resistive-type humidity detection. Comprehensive characterization of the chitosan film was performed using Fourier-transform infrared (FTIR) spectroscopy, contact angle measurements, and tensile testing, which confirmed its chemical structure, wettability, and mechanical stability.

The trace detection of pyocyanin (PCN) is crucial for infection control, and electrochemical sensing technology holds strong potential for application in this field. A pivotal challenge in utilizing carbon materials within electrochemical sensors lies in constructing carbon-based films with robust adhesion. To address this issue, a novel composite hydrogel consisting of multi-walled carbon nanotubes/polyvinyl alcohol/phosphotungstic acid (MWCNTs/PVA/PTA) was proposed in this study, resulting in the preparation of a highly sensitive and stable PCN electrochemical sensor.
