The aim of the study was to determine the effect of pituitary transcription factor 1 (POU1F1, Pit1) and the polymorphism of growth hormone releasing hormone (GHRH) genes on selected pig performance traits. The animals used were the progeny of Polish Landrace × Polish Large White crossbred sows and Polish Landrace, Polish Large White, Duroc or Pietrain boars. Eighteen perfor-mance traits were re...

b-lactoglobulin (Coded by the b-lg gene) is the major milk whey protein in ruminants. Studies have shown that this protein is polymorphic in many breeds of sheep as a result of a single base pair substitution in the b-lg gene that also gives rise to RsaI restriction fragment length polymorphism (RFLP). Blood samples were collected from 391 animals belonging to 5 Iranian and 6 Russian sheep bree...

A fragment of the gyrA gene was sequenced from 34 isolates of Campylobacter coli, including 23 isolates resistant to ciprofloxacin. All ciprofloxacin-resistant isolates examined by DNA sequencing carried a point mutation at position Thr-86 on the gyrA gene product, involving the replacement of Thr-86 by Ile. A combined PCR-restriction fragment length polymorphism technique using RsaI was develo...

The accessibility of railway stations plays a crucial role in assessing service quality, predicting travel patterns, and developing infrastructure the surrounding areas. This paper proposes station index (RsAI) (external) that incorporates various parameters, including network performance, into weighted measure. We reviewed different methods for measuring levels transit systems to identify most...

Young and Yung devised various backdoors for RSA key generation. However, due to their backdoor constructing method, the two MSBs of the modulus n generated by their systems have di¤erent distribution than that generated by the normal RSA. Thus, someone may observe the abnormal distribution of n to detect the existence of backdoors. Recently, Crepéau and Slakmon further suggested four simple wa...
