Effects of in ovo injection of nicotinamide riboside on high-yield broiler myogenesis.

The objective of this study was to determine the effects of in ovo injection of high-yield broiler embryos with nicotinamide riboside (NR) on pectoralis major muscle (PMM) development, growth, and gene expression. Fertilized Cobb 700 broiler eggs were randomly assigned to one of four treatments within a 2 × 2 factorial design. Factor 1 consisted of NR dose (DOS) with eggs receiving 0 or 2.

In Ovo Feeding of Commercial Broiler Eggs: An Accurate and Reproducible Method to Affect Muscle Development and Growth.

Within the past three decades, red meat and poultry scientists focused on developing strategies and technologies to manipulate muscle development during embryonic and fetal development. This area continues to be an area of focus because muscle fiber number is established during this time and determines the basis for all future growth. In poultry, numerous studies demonstrated in ovo feeding of growth factors, vitamins, or other nutrients improved chick embryonic muscle and intestinal development.

Moderate obstructive sleep apnea and cardiovascular outcomes in older adults: a propensity score-matched multicenter study (CPAGE-MODE study).

Study Objectives: Obstructive sleep apnea (OSA) has been associated with cardiovascular events (CVEs), although recent randomized controlled trials have not demonstrated that long-term continuous positive airway pressure (CPAP) prevents CVEs. Our objective was to determine the effect of CPAP on older adults with moderate OSA regarding CVE reduction.

Methods: An observational and multicenter study of a cohort of older adults (> 70 years of age) diagnosed with moderate OSA (apnea-hypopnea index 15.

Effects of extended postmortem aging and intramuscular location on protein degradation, muscle fiber morphometrics, and tenderness of beef longissimus lumborum and semitendinosus steaks.

The objective of this study was to determine effects of extended aging and intramuscular location on Warner-Bratzler shear force (WBSF), muscle fiber cross-sectional area (CSA), and protein degradation of semitendinosus (ST) and longissimus lumborum (LL) steaks. Left ST and LL were removed from 40 carcasses at 6 d postmortem. The ST was fabricated into five locations (LOC), with LOC 1 being most proximal and LOC 5 being most distal.

Improvement in Serum Anti-Müllerian Hormone Levels in Infertile Patients after Hyperbaric Oxygen (preliminary results).

Objective: To assess whether hyperbaric oxygen sessions elevate serum levels of anti-Müllerian hormone (AMH) in patients diagnosed with infertility with serum levels of less than or equal to 1 ng/dl AMH.

Methods: A study was performed on 4 patients diagnosed with infertility. Serum AMH level was measured at the beginning and end of hyperbaric oxygen sessions, and endometrial thickness was measured on endometrial cycle day 14 before and during the hyperbaric oxygen sessions.
