Background: Considering the increasing interest in strategies to prevent osteoporosis and other bone-related conditions, it is relevant to critically assess the existing evidence on the potential benefits of phenolic compounds in wine on bone metabolism. Objectives: This integrative review aims to evaluate clinical and animal studies investigating the influence of wine consumption on bone mineral density (BMD). Methods: The search was conducted in PubMed, Scopus, and Embase databases until April 2025. The key question was: “Does wine consumption influence BMD?”. Results: After searching the identified databases, 108 studies were screened, and 7 were included in the final analysis. Conclusions: This review suggests a possible association between light to moderate wine consumption and favorable effects on BMD, particularly in the spine and femoral neck. However, these findings should be interpreted cautiously due to the predominance of observational studies. Future RCTs and systematic reviews must clarify wine’s potential role in bone health and explore non-alcoholic or low-alcohol wine alternatives with similar polyphenol content.

Skin aging is a complex biological process characterized by progressive alterations in the dermal microenvironment, including extracellular matrix (ECM) disorganization, fibroblast dysfunction, and changes in the biomechanical properties of the tissue. In this context, biomaterials used in regenerative aesthetic medicine have been widely employed with the aim of stimulating dermal remodeling processes. This review aimed to analyze the main biomaterials currently used in clinical practice, including calcium hydroxyapatite, poly-L-lactic acid, polycaprolactone, polynucleotides, polydeoxyribonucleotide, and nano-hydroxyapatite, focusing on their biological mechanisms and interactions with the cutaneous microenvironment. The available literature suggests that the effects of these materials are not limited to collagen induction, but also involve modulation of fibroblast activity, extracellular matrix reorganization, and progressive tissue remodeling processes. However, relevant limitations remain in the scientific literature, including methodological heterogeneity among studies and the scarcity of evidence directly clarifying the cellular mechanisms involved. Therefore, advances in this field depend on the integration of experimental research, histological analysis, and well-controlled clinical investigation, as well as a deeper understanding of cellular biology and extracellular matrix dynamics.

The conservation of cadaverous parts of human beings in formaldehyde is classically used through an aqueous solution of formaldehyde, reported in the literature as having the best action against microorganisms. However, studies have shown that some microorganisms have potential for resistance to formaldehyde, such as some fungi and bacteria, which are able to colonize man and animals, causing various infectious conditions and pathologies. In order to verify the possible growth of these microorganisms in human anatomy pieces preserved in formaldehyde, from the anatomy laboratory of a private Faculty in Bauru (São Paulo, Brazil), samples were collected through superficial scraping in the parts of the central nervous system (brain). After collection, an analysis of the growth of fungi and bacteria was carried out. It was found in the brain samples studied that 10% formaldehyde was not able to totally prevent the growth of microorganisms, fungi and bacteria, but it guarantees the non-growth of microorganisms in large quantities.
