Nowadays, with the changing climatic conditions due to global warming, seasonal estrus cycle in cats has reached point where it can spread almost throughout year. This situation brought many problems it. Mammary tumors and mammary gland hyperplasia are most common cases mammarytissue, which occur as a result of medical interventions for reproductive control. In this review, information about et...

Background: Molecular marker based cancer diagnosis gaining more attention in the current genomics era. So, Hspb1 and Tp53 gene characterization and their mRNA expression might be helpful in diagnosis andprognosis ofcat mammary adenocarcinoma. It will also add informationin comparative cancer genetics and genomics. Objectives: Eight tumors of Siamese cats were analyzed to ascertain germ-line an...

the internal mammary artery (ima) is currently the preferred conduit for myocardial revascularization. however, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. the mechanism of spasm has not been clearly defined. since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...

b a ckground: the management of internal mammary (im) nodes in breast cancer lacks a well-defined consensus. lymphoscintigraphy identifies up to one-third of breast cancer patients with extra-axillary drainage, which is mainly located in the im chain. our aim in this meta-analysis is to identify the lymphoscintigraphy technique variables that effect im node identification. m ethods: an internet...

BACKGROUND Mammary stem cells are maintained within specific microenvironments and recruited throughout lifetime to reconstitute de novo the mammary gland. Mammary stem cells have been isolated through the identification of specific cell surface markers and in vivo transplantation into cleared mammary fat pads. Accumulating evidence showed that during the reformation of mammary stem cell niches...

Despite a lot of research, the etiology and progression of breast cancer remain incompletely understood. Recently, human cytomegalovirus (HCMV) was reported as a risk factor for breast cancer. The aim of this study was to know whether breast cancer could be caused by cytomegalovirus or not? In this experiment seventeen samples of RAZI/A mice with spontaneous breast cancer were being gathered fr...

It has been reported that twice-weekly i.p. injections of 4 mg phorbol for 10 weeks, after a single feeding of 6 mg dimethylbenz(a)anthracene (DMBA) in female Wistar rats, led to a significant augmentation of mammary adenocarcinoma incidence and of lymphatic leukemia incidence as compared to 6 mg DMBA alone. In an experiment reported here, in female Sprague-Dawley rats, using the same doses of ...

Although mouse models have provided invaluable information on the mechanisms of mammary gland development, anatomical and developmental differences between human and mice limit full understanding of this fundamental process. Humanization of the mouse mammary gland by injecting immortalized human breast stromal cells into the cleared murine mammary fat pad enables the growth and development of h...
