Biological sex estimation in experimentally burnt patellae: exploring sexual dimorphism through comparative analysis.

The patella has been used in various studies to verify its value in the estimation of biological sex. However, there is limited understanding regarding the alterations the bone undergoes when exposed to the effects of fire and how it affects sexual dimorphism. The current study aims to study the efficacy of three patella measurements, and generate an equation and cut-off points, to estimate the sex of individuals that had their patellae subjected to burning.

Discovery of mammalian collagens I and III within ancient poriferan biopolymer spongin.

Spongin is a fundamental biopolymer that has played a crucial role in the skeletogenesis of keratosan sponges for over 800 million years. This biomaterial had so far remained chemically unidentified and believed to be an enigmatic type of halogenated collagen-keratin-based bioelastomer. Here we show collagen I and III as the main structural components of spongin.

Percutaneous Endoscopic Gastrostomy in the 21st Century-An Overview of 1415 Consecutive Dysphagic Adult Patients.

Percutaneous endoscopic gastrostomy (PEG) is recommended for long-term enteral nutrition in dysphagic patients. This study aims to characterize conditions motivating PEG, assess nutritional status on the gastrostomy day, evaluate survival and search for survival predictors. Retrospective study of adult patients who underwent PEG in a tertiary hospital from 2001 to 2023.

Osteogenic differentiation of rat bone mesenchymal stem cells cultured on bioceramic scaffolds (alpha-TCP-RL, SiTCP-RL, and SiTCP-RC).

We evaluated the viability of Vero and the osteogenic differentiation potential of mesenchymal stem cells (MSCs) cells cultured on alpha-TCP-RL, SiTCP-RL, and SiTCP-RC bioceramic scaffolds. Viability of Vero cells and MSCs were evaluated by the MTT assay. The morphological pattern of the two cell types was analyzed by SEM.

Primary Pulmonary Epithelial-Myoepithelial Carcinoma: A Case Report and Comprehensive Literature Review of a Rare Lung Neoplasm.

Primary epithelial-myoepithelial carcinoma (EMC) of the lung is a rare subtype of pulmonary tumors. Originating from bronchial submucosal glands, EMC shares histopathological characteristics with its salivary gland counterparts and typically presents as a low-grade malignancy. Due to its rarity, there is limited literature to guide diagnosis and management.
