Preface

Abstract

This inaugural volume includes five manuscripts. Four original papers based clinical and nonclinical studies in small and large domesticated animals and an invited review article are presented to the readers of TRVS. In this issue, Szczepanek et al. have reviewed the role of microRNA in domestic animals. They summarized the existing knowledge about miRNAs synthesis, mechanisms for regulation of the genome their functions in animals physiology; microRNAs as potential biomarkers for veterinary research; the implications associated with dysfunction and dysregulation. Review concludes that microRNA molecules are great targets for understanding biology, physiology and pathology in veterinary science. In the near future, these molecules may become very attractive features for their immediate implementation as biomarkers for many diseases and may contribute to enhancing global agricultural production as well. Brüssow et al. original paper analyzed the impact of unilateral ovarian removal (uni-OXV) on ovarian function, steroid hormone level, fetal distribution and development in gilts. Study concludes that by comparing to intact gilts, only long term uni-OVX could compensate ovarian development. However, short term uni-OVX affects the total number of CL and fetuses, distribution and weight of fetuses in uterine horns and steroid hormone levels. Gehrke et al. original paper reported the relations between feto-pelvic proportion and fertility of black-and-white and red-and-white Polish Holstein-Friesian cows. Study concludes that process of "Holsteinization" of domestic headache of cattle requires selection of bull's semen not only for heifers but also older cows. Wysocka et al. original paper predicted the hepatic and pituitary gland expression of potential candidate genes in context to maintenance of oxidative balance, negative nitrogen balance, and ketosis in Polish HF and Polish Red cattle. Study conclude that understanding the genetic factors that predispose metabolic disorders in cattle would benefit the dairy industry as a whole by providing producers, breeding services, and veterinarians a tool to forecast a cow's susceptibility to metabolic disorders. Felsmann and Felsmann original paper examined the impact of changes in Polish law on the possibility of interrupting the spread toxoplasmosis and toxocarosis. Study updated the new changes in the Polish legal acts (acts and regulations) made in recent years in context to combat toxocarosis and toxoplasmosis by the legal authorities of Polish government administration. Study concluded that state public health services do not currently possess the legal means necessary to take effective action leading to the blocking of pathways along which these zoonosis spread.
