Effect of the bovine TG5 gene polymorphism on milk- and meat-producing ability.

AIM: This study aimed to determine the effect of thyroglobulin (TG5) gene polymorphism on milk and meat productivity in the various cattle breeds currently bred in the Republic of Bashkortostan. MATERIALS AND METHODS: The test was performed on dairy cattle of Black-and-White, Bestuzhev, and Simmental breeds, and meat cattle of Hereford and limousine breeds. The purpose of the test was to search for associations between the polymorphic alleles of the thyroglobulin (TG5) gene and economically useful traits. RESULTS: All studied breeds showed a frequency predominance of the TG5C allele (from 0.56 to 0.71). A clear trend of an effect of the genotypes of the TG5 gene on milk-productivity indicators was revealed; cows with the TG5TT genotype have the highest milk yield and fat content in milk. The milk of cows of Bestuzhev and Simmental breeds that possessed this genotype was also characterized by higher protein content. CONCLUSION: We identified an effect of the polymorphism of the TG5 gene in the Hereford and limousine breeds on fat metabolism intensity indicators, such as fat output and fat content, in the longissimus muscle and in the general sample of ground beef.

[The evolution of adenoidectomy].

The critical analysis of publications concerning methods designed for the surgical treatment of adenoids is presented. Various surgical techniques are considered with special reference to their indications for use, invasiveness, effectiveness, and safety. Recent developments in this field give evidence that evolution of adenoidectomy brought about highly efficacious (up to 99%) mini-invasive and safe surgical procedures producing the minimal risk of relapses and postoperative complications. All these advancements became possible due to the introduction of endoscopic intraoperative control, general anesthesia, and the use of modern surgical instruments. Modern approaches make unnecessary radical removal of the lymphoid tissue.

[The clinical effectiveness of the antiseptic treatment of the operative field for endoscopic adenotomy].

The objective of the present controlled randomized study was to estimate the clinical effectiveness of the antiseptic treatment of the operative field for endoscopic adenotomy. It is based on the results of the examination and treatment of 202 children at the age varying from 4 to 10 years admitted with the diagnosis of adenoids for the planned surgical intervention between 2010 and 2012. The results of the study indicate that postoperative objective and subjective symptoms of the disease were significantly less pronounced in the case of the preoperative treatment of the operative field than without it. Specifically, statistically significant reduction in the severity of postoperative reactive inflammation was documented. Double antiseptic washing of the nasopharynx caused neither complications nor undesirable adverse reactions and significantly reduced the requirements for systemic antibacterial preparations and anesthetics. It is concluded that the preoperative antiseptic treatment of the operative field for endoscopic adenotomy is a safe and effective procedure that can be recommended for a wider clinical application.
