Article Synopsis
  • - A bio-guided isolation process led to the discovery of six compounds from the Vietnamese lichen Roccella montagnei, including a new compound named montagneside A, alongside five known compounds.
  • - The chemical structures of these compounds were determined using advanced techniques like 1D and 2D NMR analysis and high-resolution mass spectroscopy.
  • - Evaluation of the compounds showed that D-erythrin and its derivatives significantly inhibited alpha-glucosidase activity, with the most active derivative being analyzed through molecular docking to understand its inhibitory mechanism.

Phenotypic degeneration in Cordyceps militaris poses a significant concern for producers, yet the mechanisms underlying this phenomenon remain elusive. To address this concern, we isolated two strains that differ in their abilities to form fruiting bodies. Our observations revealed that the degenerated strain lost the capacity to develop fruiting bodies, exhibited limited radial expansion, increased spore density, and elevated intracellular glycerol levels.

Article Synopsis
  • - The study investigates how arsenic (As) stress impacts the physiology of the microalga Diacronema lutheri using non-destructive methods, particularly variable fluorescence, to identify stress markers at two arsenic concentrations (11.25 µg/L and 22.5 µg/L) compared to a control.
  • - Results showed that growth metrics like cell density and chlorophyll a levels were negatively affected by arsenic exposure after the exponential growth phase, while certain photo-physiological indicators, such as light absorption, actually increased despite a decrease in biomass production.
  • - The research indicates that arsenic exposure leads to heightened energy dissipation and affects photoprotective pigments, highlighting the importance of using photo

Aim: This article aims to determine the contributing indications for primary cesarean sections among full-term pregnant women with non-previous uterine scars and suggests several potential solutions to reduce the cesarean section rate.

Methods: This is a descriptive study with data being retrospectively collected from electronic medical records (EMRs) at Hanoi Obstetrics & Gynecology Hospital, Vietnam, in 2020. We studied 23,631 women at ≥37 weeks of gestation with non-previous uterine scars.

The current study used data surveyed with 5357 parents/guardians (parents would be used to represent both 'parents' and 'guardians' hereafter) between February and March 2022 in Vietnam to examine their willingness to vaccinate their children with current COVID-19 vaccines. It applied the multinomial logistic regression model to examine the association between the willingness of parents and selected influential factors. In addition, the reasons that made parent hesitant or unwilling to vaccinate their children were investigated.
