Physiological impacts of overweight on semen parameters and fertility in male broiler breeders.

A negative correlation between growth and reproductive traits has declined fertility in the second half of the flock's reproductive life. Excessive weight gain in males is one of the crucial reasons for the reduction of fertility rate in broiler breeder flocks. Field data from commercial flocks were collected at different ages to determine the excess weight of roosters.

Differences in Medicare payment and practice characteristics for orthopedic surgery subspecialties.

Background: Medicare payment, practice, and patient characteristics give perspective on the lifestyle, challenges, and attractiveness unique to each orthopedic surgery subspecialty. Changes to Medicare reimbursement may also affect health care delivery, warranting policy change. We analyzed differences in orthopedic surgery subspecialty characteristics and Medicare payments.

Oncolytic reprogramming of tumor microenvironment shapes CD4 T-cell memory via the IL6ra-Bcl6 axis for targeted control of glioblastoma.

Oncolytic viruses (OVs) emerge as a promising cancer immunotherapy. However, the temporal impact on tumor cells and the tumor microenvironment, and the nature of anti-tumor immunity post-therapy remain largely unclear. Here we report that CD4 T cells are required for durable tumor control in syngeneic murine models of glioblastoma multiforme after treatment with an oncolytic herpes simplex virus (oHSV) engineered to express IL-12.

Folded-flap palatoplasty is not superior to cut-and-sew staphylectomy for the treatment of brachycephalic obstructive airway syndrome in English Bulldogs.

Objective: To determine whether folded-flap palatoplasty (FFP) results in improved respiratory outcomes compared to standard staphylectomy (SS).

Methods: English Bulldogs were randomized to receive FFP or SS in a parallel, equal-allocation, prospective study design at a single institution. Exercise-tolerance testing (ETT), arterial blood gas, head CT, and an owner survey were completed preoperatively and at recheck (approx 30 days postoperatively).

Research note: Effects of L-carnitine and L-arginine on sperm quality and fertility potential of aged broiler breeder roosters.

This objective of this study was to investigate the effects of L-arginine (L-Arg) and L-carnitine (LC) and their mixture in the diet (at lower levels) on sperm quality in aging broiler breeder roosters. Thirty-two broiler breeder roosters of the Arian breed were kept at 50 wk of age after a 12-wk acclimatization period. The birds were divided into four treatments and eight replicates in a completely randomized design.
