Safety of two-dose schedule of COVID-19 adsorbed inactivated vaccine (CoronaVac; Sinovac/Butantan) and heterologous additional doses of mRNA BNT162b2 (Pfizer/BioNTech) in immunocompromised and immunocompetent individuals.

Immunocompromised individuals were considered high-risk for severe disease due to SARS COV-2 infection. This study aimed to describe the safety of two doses of COVID-19 adsorbed inactivated vaccine (CoronaVac; Sinovac/Butantan), followed by additional doses of mRNA BNT162b2 (Pfizer/BioNTech) in immunocompromised (IC) adults, compared to immunocompetent/healthy (H) individuals. This phase 4, multicenter, open label study included solid organ transplant and hematopoietic stem cell transplant recipients, cancer patients and people with inborn errors of immunity with defects in antibody production, rheumatic, end-stage chronic kidney or liver disease, who were enrolled in the IC group.

Tissue Engineering Construct for Articular Cartilage Restoration with Stromal Cells from Synovium vs. Dental Pulp-A Pre-Clinical Study.

Background/objectives: Cartilage injuries and osteoarthritis are prevalent public health problems, due to their disabling nature and economic impact. Mesenchymal stromal cells (MSCs) isolated from different tissues have the immunomodulatory capacity to regulate local joint environment. This translational study aims to compare cartilage restoration from MSCs from the synovial membrane (SM) and dental pulp (DP) by a tissue-engineered construct with Good Manufacturing Practices.

Mannich Base Derived from Lawsone Inhibits PKM2 and Induces Neoplastic Cell Death.

Pyruvate kinase M2, a central regulator of cancer cell metabolism, has garnered significant attention as a promising target for disrupting the metabolic adaptability of tumor cells. This study explores the potential of the Mannich base derived from lawsone () to interfere with PKM2 enzymatic activity both in vitro and in silico. The antiproliferative potential of was tested using MTT assay in various cell lines, including SCC-9, Hep-G2, HT-29, B16-F10, and normal human gingival fibroblast (HGF).

Computed Tomography-Guided Radiofrequency Ablation of Nasal Carcinomas in Dogs.

Nasal carcinomas in dogs are locally invasive neoplasms with a low metastatic rate that pose significant treatment challenges due to their location and aggressiveness. This study evaluates the safety, feasibility, and therapeutic outcomes of computed tomography-guided radiofrequency ablation (CT-guided RFA) in 15 dogs diagnosed with nasal adenocarcinoma. All patients underwent staging and histopathological diagnosis before treatment.

Nutritional Value of for Weaner Piglets.

This study evaluates the nutritional value of spray-dried biomass to infer its applicability for weaner piglet feeding. Twenty-four piglets were randomly allocated to four dietary treatments ( = 6) with increasing inclusion (0, 5, 10, and 15%) levels. After a 4-day adaptation period, the digestibility experiment lasted two weeks, with daily excreta collection.
