Arginine-Biofunctionalized Ternary Hydrogel Scaffolds of Carboxymethyl Cellulose-Chitosan-Polyvinyl Alcohol to Deliver Cell Therapy for Wound Healing.

Wound healing is important for skin after deep injuries or burns, which can lead to hospitalization, long-term morbidity, and mortality. In this field, tissue-engineered skin substitutes have therapy potential to assist in the treatment of acute and chronic skin wounds, where many requirements are still unmet. Hence, in this study, a novel type of biocompatible ternary polymer hybrid hydrogel scaffold was designed and produced through an entirely eco-friendly aqueous process composed of carboxymethyl cellulose, chitosan, and polyvinyl alcohol and chemically cross-linked by citric acid, forming three-dimensional (3D) matrices, which were biofunctionalized with L-arginine (L-Arg) to enhance cellular adhesion.

A Novel HLA-DPA1*02 Variant, HLA-DPA1*02:141, Identified in a Bone Marrow Donor Candidate From Brazil.

Identification of the novel HLA-DPA1*02:141 allele that differs from HLA-DPA1*02:02:02:01 at one position in exon 4.

Deoxynivalenol induces ovarian damage and uterine changes in prepubertal and adult mice.

Deoxynivalenol (DON) is associated with reproductive toxicity in animals. The frequent contamination of cereal-based foods with DON and the high intake of these by children raises particular concern about the susceptibility of this subpopulation to adverse effects from this mycotoxin. However, age-related differences in the in vivo reproductive toxicity of DON have not been evaluated.

Custo-Efetividade de Diferentes Tratamentos Minimamente Invasivos Para Disfunção Temporomandibular de Origem Articular sob a Perspectiva do Sistema Público de Saúde Brasileiro.

Objective: This study aimed to evaluate the cost-effectiveness (CE) of minimally invasive interventions for pain associated with articular temporomandibular dysfunction from the Brazilian Public Health System (SUS) perspective.

Methods: This is a CE study with a 1-year time horizon. Effectiveness data were extracted from a network meta-analysis, and 2 treatments with moderate levels of evidence certainty were evaluated: arthrocentesis (ARTRO) plus intra-articular corticosteroid (CO) injection and ARTRO plus intra-articular injection of sodium hyaluronate (SH).
