A Higher-Protein, Energy Restriction Diet Containing 4 Servings of Fresh, Lean Beef per Day Does Not Negatively Influence Circulating miRNAs Associated with Cardiometabolic Disease Risk in Women with Overweight.

This study examined the acute effects of 7-d energy restriction normal-protein (NP; ∼15% of daily intake as protein) compared with higher-protein (HP; ∼38% of daily intake as protein) diets varying in quantities of fresh, lean beef on circulating miRNA expression associated with cardiometabolic disease in 16 women with overweight (mean ± SD; age: 35 ± 8.7 y; body mass index: 28.5 ± 1.

Higher Expression of miR-15b-5p with Inclusion of Fresh, Lean Beef as Part of a Healthy Dietary Pattern Is Inversely Associated with Markers of Cardiometabolic Disease Risk.

Background: Considerable controversy exists surrounding the consumption of red meat and its impacts on cardiometabolic health and if it may further impact risk factors at the molecular level.

Objective: The purpose of this study was to examine the acute effects of dietary patterns, varying in red meat quantity, on the expression of circulating microRNAs (miRNAs), which are emerging biomarkers of metabolic dysfunction and chronic disease severity.

Methods: Secondary analyses were performed on plasma samples collected within a randomized, crossover design study in 16 women with overweight (mean ± standard deviation, age = 33 ± 9.

Technical note: an optimized method to isolate, purify, and differentiate satellite cells from broiler chicks.

Development and maintenance of healthy muscle fibers rely on the myogenic potential of satellite cells (SC), muscle stem cells that proliferate and differentiate to form myotubes. Satellite cells are indispensable for post-hatch muscle growth as well as muscle repair and regeneration when myofibers are damaged. Pectoralis major of young broiler chicks (5-d olds) is a readily available source of SC, which can be used in vitro to elucidate cellular and molecular mechanisms responsible for muscle growth and regeneration in broilers.

Prenatal sonographic diagnosis of vasa previa: ultrasound findings and obstetric outcome in ten cases.

Objective: To assess the specificity of sonographic diagnosis of vasa previa and pregnancy outcome in sonographically diagnosed cases.

Methods: We prospectively collected cases of vasa previa diagnosed by color Doppler sonography. Delivery by elective Cesarean section after demonstration of fetal pulmonary maturity and prior to the onset of labor was recommended unless obstetric complications supervened.
