Effect of Flower and Leaf Extract on the Functional, Antioxidant, Rheological, Textural, and Sensory Properties of Goat Yogurt.

The present study aimed to evaluate the effects of incorporating different concentrations (1% and 2%) of Malvaviscus arboreus flower (FE) and leaf (LE) extracts as functional ingredients in goat milk yogurt. This study analyzed the impact of these formulations (YFE1%, YFE2%, YLE1%, and YLE2%) on the physicochemical, bioactive, antioxidant, rheological, textural, and sensory properties of goat yogurt over a 28-day storage period. Including FE and LE extracts significantly enhanced the yogurt's antioxidant activity, reaching up to 10.

The Use of Mesenchymal Stromal/Stem Cells (MSC) for Periodontal and Peri-implant Regeneration: Scoping Review.

The necessity for regenerating peri-implant and periodontal tissues is increasingly apparent. Periodontal diseases can result in a significant loss of clinical attachment level, and tissue regeneration stands as the ultimate goal of periodontal therapy. With the rise of osseointegration, the prosthetic rehabilitation of missing teeth using dental implants has surged, leading to a frequent need for alveolar bone regeneration around implants.

Dual modification of starch: Synergistic effects of ozonation and pulsed electric fields on structural, rheological, and functional attributes.

Study evaluated the influence of ozonization (O) time combined with pulsed electric fields (PEF) on the modification of bean starch structure. O₃ was used at a concentration of 0.045 g/L for 60 min (Oz1) and 120 min (Oz2) both individually and in combination with 30 kV/cm (P30).

Repeated subcutaneous esketamine on treatment-resistant depression: An open-label dose titration study.

Background: Ketamine has gained prominence as one of the most effective therapeutic options in unipolar treatment-resistant depression (TRD). However, most studies related to the antidepressant action of ketamine used intravenous (IV) or intranasal (IN) administration. The subcutaneous (SC) route of administration is a promising alternative, as it results in plasma levels comparable to IV, causes fewer side effects, and is easier and cheaper to administer than both IV and/or IN routes.

Determination of drugs of abuse and metabolites in plasma microsamples by LC-MS/MS after microQuEChERS extraction.

Identifying drugs of abuse and their metabolites in plasma is vital in both forensic and clinical toxicology. While the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) method offers an efficient approach to sample preparation, its application is complex due to the wide-ranging properties of target analytes and the challenges posed by biological matrix interferences. This study aims to develop a microQuEChERS approach for the quantification of 14 drugs of abuse and metabolites utilizing minimal sample and solvent volumes.

Copaifera spp. oleoresins control Trypanosoma cruzi infection in human trophoblast cells (BeWo) and placental explants.

Congenital Chagas disease (CCD) is a worldwide neglected problem with significant treatment limitations. This study aimed to evaluate the potential of Copaifera spp. oleoresins (ORs) against Trypanosoma cruzi infection in trophoblast cells (BeWo lineage) and human chorionic villous explants (HCVE).

Zika virus capsid protein closed structure modulates binding to host lipid systems.

Zika virus (ZIKV), a mosquito-borne Flavivirus of international concern, causes congenital microcephaly in newborns and Guillain-Barré syndrome in adults. ZIKV capsid (C) protein, one of three key structural proteins, is essential for viral assembly and encapsidation. In dengue virus, a closely related flavivirus, the homologous C protein interacts with host lipid systems, namely intracellular lipid droplets, for successful viral replication.

Combined effects of high hydrostatic pressure and pulsed electric fields on quinoa starch: Analysis of microstructure, morphology, thermal, and pasting properties.

The aim of this study was to evaluate the impact of non-thermal methods, using high hydrostatic pressure (HHP) and pulsed electric field (PEF), on the dual modification of quinoa starch and to analyze the microstructural, morphological, thermal, pasting, and texture properties. Starch was treated with HHP at 400 MPa for 10 min, while PEF was applied using voltages of 10 and 30 kV cm for a total time of 90s. The modification techniques were effective in breaking down amylose molecules and amylopectin branches, where for the dual treatment, higher values of DP6-12 were found.

Cell Cycle Kinetics and Sister Chromatid Exchange in Mosaic Turner Syndrome.

Turner syndrome (TS) is caused by a complete or partial absence of an X or Y chromosome, including chromosomal mosaicism, affecting 1 in 2500 female live births. Sister chromatid exchange (SCE) is used as a sensitive indicator of spontaneous chromosome instability. Cells from mosaic patients constitute useful material for SCE evaluations as they grow under the influence of the same genetic background and endogenous and exogenous factors.

Assessment of health-related quality of life after mild COVID-19 infection.

Introduction: Coronavirus disease 19 (COVID-19) affected the health-related quality of life (HRQoL), and its impact on well-being is not sufficiently understood yet. The worsening of HRQoL and symptoms such as fatigue, anxiety, depression, chronic Headache, Myalgia, ageusia, olfactory disorders, and cognitive impairment can be seen in people of different ages and genders after COVID-19 infection, even mild infections without hospitalization. These issues generate a disease burden that can reduce work skills and cause social, psychological, and neuropsychiatric challenges.

Connexin43 promotes exocytosis of damaged lysosomes through actin remodelling.

A robust and efficient cellular response to lysosomal membrane damage prevents leakage from the lysosome lumen into the cytoplasm. This response is understood to happen through either lysosomal membrane repair or lysophagy. Here we report exocytosis as a third response mechanism to lysosomal damage, which is further potentiated when membrane repair or lysosomal degradation mechanisms are impaired.

Antiviral Activities of Mastoparan-L-Derived Peptides against Human Alphaherpesvirus 1.

Human alphaherpesvirus 1 (HSV-1) is a significantly widespread viral pathogen causing recurrent infections that are currently incurable despite available treatment protocols. Studies have highlighted the potential of antimicrobial peptides sourced from venom, particularly those belonging to the mastoparan family, as effective against HSV-1. This study aimed to demonstrate the antiviral properties of mastoparans, including mastoparan-L [I, R], mastoparan-MO, and [I, R] mastoparan, against HSV-1.

Maternal pregnancy hypertension impairs nitric oxide formation and results in increased arterial blood pressure in first-generation offspring female rats.

Objectives: Maternal endothelial dysfunction in pregnancy hypertension is related to impairment of nitric oxide (NO) formation. However, NO levels and hemodynamic repercussions on the female offspring remain unclear. Therefore, this study hypothesized that maternal pregnancy hypertension reduces circulating NO metabolites and increases arterial blood pressure in first-generation offspring female rats.
