A characterization of the humoral immune response of alpacas to Fasciola hepatica Fas1 and Fas2 antigens cysteine proteinases was performed over the course of 6 months of experimental infection. Six adult alpacas aged 1 to 2 years old received a single dose of 200 F. hepatica metacercariae, 2 non–infected alpacas were kept as control group. Peripheral eosinophilia in infected animals was greatl...

Background: It is demonstrated that c-Kit( receptor of stem cell factor) mRNA is expressed in late 2-cell stage to the expanded and hatched blastocyst and the stem cell factor (SCF) transcript is detected in the oviduct and uterus. The aim of this study was to investigate the effect of different doses of SCF on mouse 2-cell embryo development in vitro. Materials and Methods: 4-6 weeks old femal...

PURPOSE Inhibitors of farnesyltransferase (e.g., R115777) are being developed for therapy and prevention of various cancers. The efficacy of R115777 [Zarnestra; (B)-6-[amino(4-chlorophenyl)(1-methyl-1H-imidazol-5-yl)-methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone] to prevent the development of lung tumors in mice was determined. EXPERIMENTAL DESIGN Female strain A mice (7-8 weeks of ag...

background: radiotherapy is one of the most important factors which results in negative effects on wound healing and increases anastomosis leakage. diverting loop ileostomy has been usually performed after colorectal anastomosis in cases of colorectal cancer with a history of neoadjuvant radiotherapy to decrease the chance of leakage. considering the side effects of diverting loop ileostomy, th...
