We aimed to evaluate the reproductive efficiency of Nelore cows in fixed-time artificial insemination (FTAI) programs with early resynchronization. A total of 468 Nelore cows were divided into two experimental groups: R30-conventional resynchronization at 30 days ( = 234); R22-early resynchronization at 22 days ( = 234). Both groups followed a synchronization protocol using intravaginal progesterone devices combined with the administration of steroids and gonadotropins.

Cellulose-based materials are promising adsorbents for pollutants and other classes of compounds. Here, we report the preparation of hydrogels via chemical cross-linking of microcrystalline cellulose oxidized by the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO). The cross-linking process was carried out in the presence of modifiers such as β-cyclodextrin in order to insert hydrophobic cavities or κ-carrageenan due to the presence of negative charges along the molecular chains.

Objective: to map the evidence of the use of telenursing in adherence to treatment and promotion of self-care in patients with chronic renal insufficiency undergoing conservative treatment.

Method: scoping review study, with selection of documents indexed in eight databases and two catalogs of theses and dissertations. Additionally, the reference lists of selected studies were consulted.

Article Synopsis
  • - The study synthesized zinc oxide nanoparticles (ZnO NPs) using an environmentally friendly method with Batavia lettuce extract, allowing for a simple and rapid creation process.
  • - Characterization revealed that the ZnO NPs have a small average diameter of 6 nm, a wurtzite crystalline structure, and emit blue fluorescence when excited, making them suitable for detecting ascorbic acid (AA).
  • - The fluorescence sensing method showed high sensitivity and rapid detection capabilities for AA at a limit of 5.15 μM and maintained photostability, indicating its potential use in clinical analysis.

For the first time, ultrafiltration (UF) green membranes were prepared through a sustainable route by using PLA as a biopolymer and dihydrolevoclucosenone, whose trade name is Cyrene™ (Cyr), dimethyl isosorbide (DMI), and ethyl lactate (EL) as biobased solvents. The influence of physical-chemical properties of the solvent on the final membrane morphology and performance was evaluated. The variation of polymer concentration in the casting solution, as well as the presence of Pluronic (Plu) as a pore former agent, were assessed as well.
