Polyamide Microparticles with Immobilized Enological Pectinase as Efficient Biocatalysts for Wine Clarification: The Role of the Polymer Support.

Free pectinase is commonly employed as a biocatalyst in wine clarification; however, its removal, recovery, and reuse are not feasible. To address these limitations, this study focuses on the immobilization of a commercial pectinolytic preparation (Pec) onto highly porous polymer microparticles (MPs). Seven microparticulate polyamide (PA) supports, namely PA4, PA6, PA12 (with and without magnetic properties), and the copolymeric PA612 MP, were synthesized through activated anionic ring-opening polymerization of various lactams.

Temporal Unfolding of Spelling-to-sound Mappings in Visual (Non)word Recognition.

Behavioral research has shown that inconsistency in spelling-to-sound mappings slows visual word recognition and word naming. However, the time course of this effect remains underexplored. To address this, we asked skilled adult readers to perform a 1-back repetition detection task that did not explicitly involve phonological coding, in which we manipulated lexicality (high-frequency words vs.

Age- and Sex-Related Volumetric Density Differences in Trabecular and Cortical Bone of the Proximal Femur in Healthy Population.

Background: There are age- and sex-related increases in the prevalence of osteoporosis. Bone densitometry based on dual energy X-ray absorptiometry (DXA) is the gold standard for the assessment of bone mineral density (BMD). Three-dimensional (3D) analysis of the proximal femur (3D-DXA) allows discrimination between cortical and trabecular compartments, and it has shown a good correlation with computed tomography.

Genetic study on candidates for oocyte donation.

Objective: There is a rising demand for assisted reproductive medicine, including sperm, oocyte and embryo donation. Besides medical and legal considerations, genetic testing, including carrier screening for multiple autosomal and X-linked recessive disorders plays an essential role in evaluating hereditary risk among donors and therefore exclude them from the donation process.

Methods: A retrospective study was conducted on oocyte donors from a private clinic of assisted reproduction who underwent genetic testing between June 2014 and September 2023.

Antimicrobial Effect of Diphenyl Ditelluride (PhTe) in a Model of Infection by in .

Diphenyl ditelluride (PhTe), an organotelluric compound with pharmacological and toxicological attributes, has shown promise in microorganism studies. , an alternative animal model, is gaining popularity for novel antimicrobial research due to its cost-effectiveness, versatility, and similarity to vertebrate models. Given the rising antibiotic resistance, particularly in (), the exploration of novel antimicrobials is of utmost importance.
