Seasonal variations in ventricular repolarization and tachyarrhythmias in hibernating brown bears (Ursus arctos arctos).

In humans, hypothermia prolongs ventricular repolarization and associates with sustained ventricular tachyarrhythmias. In bears, body temperature drops during hibernation similar to moderate human hypothermia, yet they rarely face fatal outcomes during the winter. This suggests protective adaptations in bear electrophysiology.

Evaluating high-protein wheat as a protein source for broiler chicken.

Today, broiler feed formulators focus not only on minimizing costs but also on reducing environmental impact and maintaining broiler health. Lowering crude protein (CP) levels is a key strategy for addressing these concerns. The least cost formulation of diets based on the ideal protein concept - where amino acids are provided in appropriate proportions - is the most effective way to supply an economically viable and balanced amino acids feed for broilers.

Lymphatic complications after thigh soft tissue sarcoma resection in the era before lymphatic reconstructive surgery - a retrospective cohort analysis.

Introduction: Patients undergoing curative treatment for soft-tissue sarcomas (STS) of the thigh bear the risk of developing lymphatic fistula and lymphedema. Innovative microsurgical concepts such as primary preventive lymphatic reconstruction show promising results. To discuss the likelihood of lymphatic complications after limb-preserving treatment of STS in the era before lymphatic reconstructive surgery and depending on the sarcoma location in the thigh became paramount in treating these patients.

[Reconstruction of Anorectal Defects Following Oncological Resection].

The management of anorectal carcinomas necessitates a multimodal therapeutic approach. Advances in modern medicine have reduced the incidence of complete rectal extirpations and permanent colostomies to below 10%. Despite these improvements, the reconstruction of anorectal defects, particularly following abdominoperineal extirpation (APE) or pelvic exenteration, remains a significant challenge.
