Production of free fatty acids by enzymatic hydrolysis of residual frying oil using non-commercial lipases from Aspergillus niger.

Lipases are enzymes that have an important role in the industry for their wide use, giving rise to a great interest in industrial bioprocesses due to their versatility. One of the applications is the enzymatic hydrolysis of waste oils. This work consists of evaluating the production of lipases using several concentrations of residual frying oil (RFO) and different pHs, through ANOVA analysis.

Mapping of the trans population in the Baixada Santista region, Brazil, 2023: a descriptive study.

Objective: To describe the socioeconomic and demographic characteristics of the trans population in the Baixada Santista region, São Paulo state.

Methods: This was a descriptive study involving adult trans people, selected through convenience sampling in 2023. A quantitative questionnaire was administered and in-depth interviews were conducted, which were analyzed using thematic grouping.

Assessment of Reproductive Endocrinology and Infertility Fellowship Programs Website.

The aim of the study was to assess the comprehensiveness of the Reproductive Endocrinology and Infertility (REI) fellowship program websites in North America. All active REI fellowship program websites in the United States of America (USA) and Canada were evaluated and assessed using 72-point scoring criteria. Any fellowship programs without publicly accessible websites were excluded.

Designing sustainable soil conditioners: Nanocomposite-based thermoplastic starch for enhanced soil health and crop performance.

The growing demand for sustainable solutions in agriculture, driven by global population growth and increasing soil degradation, has intensified the search for sustainable soil conditioners. This study investigated the impact of adding nanoclay (NC) and nano lignin (NL) to thermoplastic starch (TPS) on its physical, chemical, and thermal properties, its effectiveness as a soil conditioner, and its resistance to UV-C degradation. TPS nanocomposites were prepared with varying NC (3 %, 5 %, 7 %) and NL (0.

Direct and transgenerational effects of simvastatin on the metabolism of the amphipod Gammarus locusta.

In this study, untargeted Nuclear Magnetic Resonance (NMR) metabolomics was applied for the first time, to our knowledge, to assess the metabolic impact of direct and transgenerational exposure (F0 and F3 generations, respectively) of amphipods Gammarus locusta to simvastatin (SIM), a pharmaceutical widely prescribed for the treatment of hypercholesterolemia. Results revealed the important gender-dependent nature of each of these effects. Directly exposed males showed enhanced glucose catabolism and tricarboxylic acid (TCA) cycle activity, in tandem with adaptations in osmotic regulation and glyoxylate metabolism.
