The sandy soils are sensitive ecosystems, being in a precarious equilibrium with the pedolandscape conditions, any changes could bring drastically modifications into soil environment. researches had been performed Suceava Tableland, Stephan Great area, on Luvosol albic-psamic, lamelar. paper focused upper part of argic horizon, Bt1 sub-horizon characteristics at macro- and microscopic scale. In...

Granular cell tumor is a rare benign non-encapsulated tumor that mostly presents in oral cavity. Breast localization is uncommon and occurs in about one per 1000 cases of breast cancers. It mainly affects premenopausal women showing the possible role of estrogen and progesterone levels in the progression of this tumor. Granular cell tumor is a great emulator of the invasive ductal carcinoma of ...

A two dimensional bi-disperse vibrofluidized granular mixture is studied in the rapid flow regime, where particle interactions occur due to instantaneous collisions. Both experiments and simulations are carried out, and these show the existence of two phenomena which have been observed only in very dense granular flows or in equilibrium systems. The Brazil nut phenomenon, which involves the ris...

BACKGROUND AND PURPOSE Because the mechanism for scavenging acidophilic electron-dense dead neurons disseminated among the neuritic networks of surviving neurons in the ischemic penumbra of the cerebral cortex is still obscure, we investigated the fate of them up to 24 weeks after the ischemic insult. METHODS Stroke-positive animals were selected according to their stroke index score during t...

The aim of this study was to investigate the distribution and density IgG, vimentin, CD45 in mouse placenta on fourth, tenth, seventeenth days pregnancy. Strept avidin-biotin-peroxidase complex (streptABC) staining method used. On fourth day pregnancy, expression more intense around uterine glands. tenth day, vimentin positive cells were demonstrated decidua basalis mesometrial parietal trophob...

background: serological assay based on dense granular (gra) proteins of toxoplasma gondii (t. gondii) is actually the most popular laboratory diagnostic tool to detection of toxoplasmosis. we aimed to construct a recombinant gra7-ptz57rt plasmid vectors that it is suitable for sub-cloning and gra7 protein production. m aterials and methods: souris mice were used for maintaining of t. gondii tac...

purpose: to present a case of orbital granular cell tumor, a rare orbital tumor. case report: a 55-year-old woman presented with binocular diplopia and right ocular displacement. the problem had initiated 3 years ago. a firm nontender mass at the region of the right lower lid was visible. orbital ct-scan disclosed a well-defined mass in the inferior right orbit with involvement of the inferior ...

Antidiuretic hormone (ADH) induces a large increase in the water permeability of the luminal membrane of toad urinary bladder. Measured values of the diffusional water permeability coefficient, Pd(w), are spuriously low, however, because of barriers within the tissue, in series with the luminal membrane, that impede diffusion. We have now determined the water permeability coefficient of these s...
