Koi herpesvirus (KHV) infection is associated with high mortalities in both common carp (Cyprinus carpio carpio) and koi carp (Cyprinus carpio koi) worldwide. Although acute infection has been reported in both domestic and wild common carp, the status of KHV latent infection is largely unknown in wild common carp. To investigate whether KHV latency is present in wild common carp, the distributi...
Thelohanellus nikolskii infection of the common carp (Cyprinus carpio L.) has been a common parasitosis in the Central European fish farms since the first detection of the parasite about 20 years ago. This parasite, introduced from the Far East, causes intensive infection on the fins of fingerlings of the carp subspecies cultured in Europe (European carp, Cyprinus carpio carpio). This infection...
A recently reported mRNA, encoding 'carbonic anhydrase-related polypeptide' (CARP) from the Purkinje cells of mouse cerebellum, was shown to have a 30-40% deduced amino acid sequence identity with the carbonic anhydrases (CA) of mammals. In order to compare the mouse and human CARP sequences, we used the polymerase chain reaction (PCR) to amplify human CARP sequences from several cDNA libraries...
In the present paper the role of GnRH in the ultrashort loop of the negative feedback action on GnRH secretion was evaluated on the molecular level by the Real-time PCR technique. Specifically, the effect of GnRH infused into the third cerebral ventricle on the expression of GnRH and GnRH receptor (GnRH-R) genes was analyzed in the hypothalamic-pituitary unit of anestrous ewes. GnRH did not sig...
IntroductionObesity has detrimental influences on women reproductive health. There is little experience in optimizing controlled ovarian hyperstimulation (COH) protocols to treat Chinese obese patients who are undergoing vitro fertilization and embryo transfer (IVF-ET) therapy.MethodsThe clinical outcome differences were retrospectively analyzed among received gonadotrophin-releasing hormone ag...
It has become a general notion that there are multiple GnRH systems in the vertebrate brains. To measure GnRH release activities from different GnRH systems, we conducted a static incubation of brain-pituitary slices under various conditions, and GnRH released into the incubation medium was measured by RIA. The slices were divided into two parts, one containing GnRH neurons in the preoptic area...
INTRODUCTION In rheumatoid arthritis (RA), several genetic risk factors and smoking are strongly associated with the presence of anticitrullinated protein antibodies (ACPA), while much less is known about risk factors for ACPA-negative RA. Antibodies against carbamylated proteins (anti-CarP) have been described in both ACPA-positive and ACPA-negative RA patients. In this study, we have analysed...
هورمون آزادکننده گنـادوتروپین(gnrh) نقشی کلـیدی در تو لـیدمثل ایفــا می کند. gnrh از طریق رگ های باب هیپوتالاموسی- هیپوفیزی به هیپوفیز قدامی حمل شده، سبب ترشح هورمون لوتئینی (lh) و هورمون محرک فولیکولی (fsh) می شود. lh نقش مهمی در ایجاد تخمـک گذاری و ترشح هورمون های جنسی دارد. fsh نیز سبب رشد فولیکول ها قبل از تخمک گذاری در زنان و پیشبرد تشکیل اسپرماتوزوئید درمردان می شود. امروزه مشخص شده است ک...
Buchtová H. , Z. Svobodová, M. Kocour , J . Vel í‰ek: Evaluation of the Dressing Percentage of 3-year-old Experimental Scaly Crossbreds of the Common Carp (Cyprinus carpio, Linnaeus 1758) in Relation to Sex. Acta Vet. Brno 2006, 75: 123-132. The aim of the present study was to compare dressing percentages, with relation to sex, of three bisexual groups of hybrid carp, i.e. Hungarian mirror carp...
