    V magisterski nalogi smo predstavili možnost gradnje drugega bloka termoelektrarne v občini Pljevlja. Z gradnjo novega bloka TE Pljevlja želimo pokriti potrebe po električni energiji v Črni Gori in zmanjšati negativni vpliv na okolje obstoječe termoelektrarne. Predstavili smo tudi oceno vrednosti investicije za novo enoto v okviru obstoječe TE.  In this paper we present the possibility for construction of the second block thermal power plant in the municipality of Pljevlja. With the construction of a new block TPP Pljevlja we want to cover electricity demand in Montenegro and reducing the negative environmental impact of existing thermal power plants. We also presented an assessment of the value of the investment for a new unit within the existing thermal power plants

    The Role of Bone Marrow Cells in the Phenotypic Changes Associated with Diabetic Nephropathy

    <div><p>The aim of our study was to investigate the role of bone marrow cells in the phenotypic changes that occur in diabetic nephropathy. Bone marrow cells were obtained from either streptozotocin-induced diabetic or untreated control C3H/He mice and transplanted into control C3H/He mice. Eight weeks after bone marrow cell transplantation, renal morphologic changes and clinical parameters of diabetic nephropathy, including the urine albumin/creatinine ratio and glucose tolerance, were measured <i>in vivo</i>. Expression levels of the genes encoding α1 type IV collagen and transforming growth factor-β1 in the kidney were assayed. Our results demonstrated that glucose tolerance was normal in the recipients of bone marrow transplants from both diabetic and control donors. However, compared with recipients of the control bone marrow transplant, the urinary albumin/creatinine ratio, glomerular size, and the mesangial/glomerular area ratio increased 3.3-fold (p < 0.01), 1.23-fold (p < 0.01), and 2.13-fold (p < 0.001), respectively, in the recipients of the diabetic bone marrow transplant. Expression levels of the genes encoding glomerular α1 type IV collagen and transforming growth factor-β1 were also significantly increased (p < 0.01) in the recipients of the diabetic bone marrow transplant. Our data suggest that bone marrow cells from the STZ-induced diabetic mice can confer a diabetic phenotype to recipient control mice without the presence of hyperglycemia.</p></div

    Sequential Superresolution Imaging of Multiple Targets Using a Single Fluorophore

    No full text
    <div><p>Fluorescence superresolution (SR) microscopy, or fluorescence nanoscopy, provides nanometer scale detail of cellular structures and allows for imaging of biological processes at the molecular level. Specific SR imaging methods, such as localization-based imaging, rely on stochastic transitions between on (fluorescent) and off (dark) states of fluorophores. Imaging multiple cellular structures using multi-color imaging is complicated and limited by the differing properties of various organic dyes including their fluorescent state duty cycle, photons per switching event, number of fluorescent cycles before irreversible photobleaching, and overall sensitivity to buffer conditions. In addition, multiple color imaging requires consideration of multiple optical paths or chromatic aberration that can lead to differential aberrations that are important at the nanometer scale. Here, we report a method for sequential labeling and imaging that allows for SR imaging of multiple targets using a single fluorophore with negligible cross-talk between images. Using brightfield image correlation to register and overlay multiple image acquisitions with ~10 nm overlay precision in the <i>x-y</i> imaging plane, we have exploited the optimal properties of AlexaFluor647 for dSTORM to image four distinct cellular proteins. We also visualize the changes in co-localization of the epidermal growth factor (EGF) receptor and clathrin upon EGF addition that are consistent with clathrin-mediated endocytosis. These results are the first to demonstrate sequential SR (s-SR) imaging using direct stochastic reconstruction microscopy (dSTORM), and this method for sequential imaging can be applied to any superresolution technique.</p></div
