the ability to maintain and study human tissues in in-vivo environment has proved to be a valuable tool in breast cancer research for several decades. the most widely tissues have been xenografts established human breast cancer cell lines into athymic nude mice. the aim of this study was to provide a new accurate and affordable method for the establishment of breast cancer xenograftin nude mice...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

conclusions based on the obtained results, it was concluded that a diminished immune response caused by cytokines in acute phase response, can lead to dissemination of virus, severity of illness and increase of the mortality rate. results among 50 patients with cchf (38% female, 62% male with the age range of 18 - 63 years), the serum level of il-6 was higher than normal (7 pg/ml) in 60% of the...

Macrodystrophia lipomatosa is a rare congenital form of localized gigantism characterized by an increase in all mesenchymal elements, particularly fibroadipose tissue. MR imaging can be used to examine the soft tissue and detect the fibrous and fatty hypertrophy that characterizes this condition and also diagnose an associated fibrolipomatous hamartoma of the median or plantar nerve. We des...

in this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{a}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{a}(t)) dt +mathbf{c}$. we also observe that the effective force $mathbf{f}_e$ on that particle due to pseudo-force $mathbf{a}(t)$, is given by $ mathbf{f}_e= mathbf{f} mat...

introduction: 64cu-pyruvaldehyde-bis(n4-methylthiosemicarbazone) (64cu-ptsm)‍ is one of the most important copper radiopharmaceuticals used in clinical experiments. methods: in this work, copper-64 (t1/2=12.33 h) production has been presented followed by the synthesis of the complexing agent, ptsm, and its structure was confirmed by common spectroscopic methods followed by radiolabeling with 64...

introduction: natural biomaterials and growth factors are key factors in tissue engineering. the objective of the present study was to evaluate transforming growth factor beta 1 (tgf-β1) and curcumin on proliferation and differentiation of nasal-derived chondrocyte seeded on the fibrin glue scaffold. methods: chondrocytes were isolated from nasal samples. nasal-derived chondrocytes were seeded ...

mcm-41 is one of the groups of mesoporous materials that have wide applications as adsorbents, ion exchangers and catalyst supports. in this work spherical and rod-like mcm-41s were synthesized in homogeneous and heterogeneous reaction media, respectively. for synthesis of these materials the cationic surfactant cetyltrimethylammonium bromide (ctmabr) was used as template and tetraethylorthosil...
