objective(s):theneuroprotective effect of lithium has been attributed to its therapeutic action. however, the role of glial cells particularly astrocytes, and the possible interactions between neurons and astrocytes in neuroprotective effects of lithium have been disregarded. thus, the aim of this study was to evaluate the direct effects of lithium on brain derived neurotrophic factor (bdnf) an...
The 8–14 µm emission spectra of 12 T Tauri stars in the Taurus/Auriga dark clouds and in the TW Hydrae association obtained with the Infrared Spectro-graph (IRS 1) on board Spitzer are analyzed. Assuming the 10 µm features originate from silicate grains in the optically thin surface layers of T Tauri disks, the 8–14 µm dust emissivity for each object is derived from its Spitzer spectrum. The em...
Background: B cell CLL/lymphoma 2 protein, bcl-2, is an important anti-apoptotic factor that has been implicated in lithium’s neuroprotective effect. However, most studies have focused on assessing the effects of lithium in neurons, ignoring examination of bcl-2 in astrocytes, which also influence neuronal survival and are affected in bipolar disorder. The aim of this study was to evaluate whet...
Portland cement could be produced by heating the raw materials (clay, limestone) about 1500°C which clinker will be formed. Geochemical and mineralogical studies of clinker, Portland cement, cement kiln dust and cement mill dust have been carried out by optical microscopy, X-ray diffraction and X-ray florescence. In phase system diagram (CaO-Al2O3-SiO2), chemical components of clinker cement oc...
Objective(s) It is believed that the mesenchymal stem cell (MSC) differentiation and proliferation are the results of activation of wnt signaling pathway. On the other hand, lithium chloride is reported to be able to activate this pathway. The objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived MSC. Materials and ...
Electrochemical energy storage systems are categorized into different types, according to their mechanisms, including capacitors, supercapacitors, batteries and fuel cells. All battery systems include some main components: anode, cathode, an aqueous/non-aqueous electrolyte and a membrane that separates anode and cathode while being permeable to ions. Being one of the key parts of any new electr...
Lithium is a immunomodulator that can increase immunoglobulins to confront infectious desese. It is also able to increase the production of interleukins, interferon gamma and prostaglandins. We conducted this study to evaluate the correlation between lithium consumption and humoral immunity. Blood samples were obtained from 76 patients under lithium treatment. We classified the patients accordi...
Numerous studies have been done on using low serum lithium levels for maintenance therapy of bipolar mood disorder over the past 30-40 years. In this study we sought for the most suitable serum lithium level that having longer relapse's interval periods and less side effects as to recommended it as a maintenance serum lithium level. Thus, we studied 90 patients with bipolar mood disorder (accor...
