Brazilian version of the Kerlan-Jobe orthopedic clinic shoulder and elbow score: translation and cross-cultural adaptation.

Background: The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is commonly used to assess the functional status of athletes with conditions affecting the shoulder and elbow. However, a Brazilian Portuguese version of the KJOC questionnaire is currently unavailable.

Objectives: This study aimed to develop a Brazilian Portuguese version of the KJOC questionnaire.

Nanostructured lipid carriers for enhanced batimastat delivery across the blood-brain barrier: an in vitro study for glioblastoma treatment.

Glioblastoma presents a significant treatment challenge due to the blood-brain barrier (BBB) hindering drug delivery, and the overexpression of matrix metalloproteinases (MMPs), which promotes tumor invasiveness. This study introduces a novel nanostructured lipid carrier (NLC) system designed for the delivery of batimastat, an MMP inhibitor, across the BBB and into the glioblastoma microenvironment. The NLCs were functionalized with epidermal growth factor (EGF) and a transferrin receptor-targeting construct to enhance BBB penetration and entrapment within the tumor microenvironment.

Chronic stress triggers impairments of the redox status of salivary glands associated with different histological responses in rats.

Stress occurs as a reaction to mental and emotional pressure, anxiety, or scarring. Chronic stress is defined as constant submission to these moments. It can affect several body systems, increase blood pressure, and weaken immunity, thereby interfering with physiological health processes.

Hormonal regulation and crosstalk during early endosperm and seed coat development.

This review covers the latest developments on the regulation of early seed development by phytohormones. The development of seeds in flowering plants starts with the fertilization of the maternal gametes by two paternal sperm cells. This leads to the formation of two products, embryo and endosperm, which are surrounded by a tissue of maternal sporophytic origin, called the seed coat.
