The mechanism of translocation of peroxisomal proteins from the cytoplasm into the matrix is largely unknown. We have been studying this problem in yeast. We show that the peroxisomal targeting sequences SKL or AKL, with or without a spacer of nine glycines (G9), are sufficient to target chloramphenicol acetyltransferase (CAT) to peroxisomes of Saccharomyces cerevisiae in vivo. The mature form ...

Computerized adaptive testing (CAT) has been implemented in high-stakes examinations such as the National Council Licensure Examination-Registered Nurses in the United States since 1994. Subsequently, the National Registry of Emergency Medical Technicians in the United States adopted CAT for certifying emergency medical technicians in 2007. This was done with the goal of introducing the impleme...

One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

Adenomatous polyposis coli (APC) mutations are present in >70% of colon cancers. The APC protein binds to beta-catenin (beta-cat), a protein first identified because of its role in E-cadherin (E-cad) cell adhesion. In some colon cancers lacking APC defects, mutations in presumptive glycogen synthase kinase 3beta phosphorylation sites near the beta-cat NH2 terminus appear to render beta-cat resi...

objectives the aim of this study was to perform a histopathological and bacteriological evaluation of gastric lesions based on h. pylori and helicobacter-like organisms (hlos) in cats. materials and methods the present study was carried out on 28 cat’s (13 male and 15 female cases) gastric mucosae, which were tested by bacteriological and histopathological methods. biochemical tests such as cat...

background: toxocara is a common nematode of cats in different parts of iran. despite the close association of cats with human, no attempt has been done so far for molecular identification of this nematode in the country. therefore, current study was performed on identification of some isolates of toxocara from stray cats in shiraz, fars province, southern iran, based on morphological and molec...

background : cats play a crucial role in the epidemiology of gastrointestinal helminthic parasites and also play a major role in transmitting of these parasites through faecal contamination of soil, food or water. the aim of this study was to determine the species of gastrointestinal helminthes parasites in stray cats from a rural area of bandar-e-anzali, iran. method: gastrointestinal helminth...

pregnancy prevention raises much concern to many pet owners. female cats usually show undesirable behaviour during oestrus. nowadays, researchers try to explore the reliable and effective ways to prevent oestrus signs in queens. the results of their studies prove that hormone therapy is probably one of the most reliable methods for this purpose. the aim of our study was to compare the effect of...
