breakthrough management (bm) is a kind of an essential organizational creativity emphasized on change and transformation with relying on the theory of transformational leadership. rather than being step by step process, changes in bm seems like a move ahead rapidly. this quality is expected to cause an essential and rapid transformation in business settings. the existing research aimed to inves...

The periodic colonization of the thymus by hematopoietic progenitors is essential for the sustained differentiation of T lymphocytes. Although the myriad signals regulating the migration of these progenitors have begun to be untangled in recent years, many questions remain. The most direct means of assessing the specific roles of various chemoattractants in regulating the seeding of the thymus ...

conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...

BACKGROUND Evaluating tissue heterogeneity using non-invasive imaging could potentially improve prostate cancer assessment and treatment. METHODS 20 patients with intermediate/high-risk prostate cancer underwent diffusion kurtosis imaging, including calculation of apparent diffusion (Dapp) and kurtosis (Kapp), prior to radical prostatectomy. Whole-mount tissue composition was quantified into:...

in this paper by using the notiαon of anti fuzzy points and its besideness to andnon-quasi-coincidence with a fuzzy set the concepts of an anti fuzzy subalgebrasin bm-algebras are generalized and their inter-relations and related propertiesare investigated.

Background: Lead (Pb) is a heavy metal that has devastating effects on many animal tissues. In this study we investigated the effects of orally-dosed lead acetate II on osteocalcin gene (osteocalcin) expression in mesenchymal stem cells grown in an osteogenic medium. Osteocalcin is an abundant bone matrix differentiation protein. Methods: Twelve male Wistar rats were divided into three groups ...

introduction: multiple sclerosis (ms) has been recognized as a common neurodegenerative disease that occurs after an auto reactive t cells against myelin antigens.  demyelination and inflammation are the main features of this disease. the anti-inflammatory and neuroprotective roles of bone marrow-derived mesenchymal stem cells (bm-mscs) have been considered as a suitable treatment against autoi...
