The Tumor Microenvironment: Focus on Extracellular Matrix.

The extracellular matrix (ECM) regulates the development and maintains tissue homeostasis. The ECM is composed of a complex network of molecules presenting distinct biochemical properties to regulate cell growth, survival, motility, and differentiation. Among their components, proteoglycans (PGs) are considered one of the main components of ECM.

The uses of infrared thermography to evaluate the effects of climatic variables in bull's reproduction.

The objective of this study was to evaluate the seasonal effects of the environment on sperm quality in subtropical region determined by temperature and humidity index (THI). We used 20 Brangus bulls (5/8 Angus × 3/8 Nellore) aged approximately 24 months at the beginning of the study. Semen evaluations were performed twice per season during 1 year.

Tear ferning test in horses and its correlation with ocular surface evaluation.

Objective: To describe the tear ferning test (TFT) in healthy horses and its correlation with other parameters for evaluating the ocular surface.

Animals Studied: Thirty male and female adult healthy horses (60 eyes), of no defined breed.

Procedures: Tear sample was collected with a microcapillary tube, placed on the surface of a glass slide, and allowed to dry at room temperature.

Factor analysis of linear type traits and their relation with longevity in brazilian holstein cattle.

In this study we aimed to evaluate the reduction in dimensionality of 20 linear type traits and more final score in 14,943 Holstein cows in Brazil using factor analysis, and indicate their relationship with longevity and 305 d first lactation milk production. Low partial correlations (-0.19 to 0.
