The representation of mouse alloantigens belonging to three systems, H-2, theta and TL, on the surface of cells from thymus, spleen, lymph nodes, and peritoneal cavity, was studied by electron microscopy with ferritin-labeled antibody. As expected from earlier serological data, TL was confined to thymocytes, theta was found on thymocytes and lymphocytes, and H-2 occurred to some extent on all c...
Knockdown of mitofilin inhibits autophagy and facilitates starvation-induced apoptosis in HeLa cells
Objective(s): Mitofilin contributes to the maintenance of mitochondrial structure and functions. This study was undertaken to determine the mechanisms underlying its regulation of apoptosis. Materials and Methods: Mitofilin was knockdowned by specific short hairpin RNA (shRNA) and the stable HeLa cell clone was selected. The autophagy a...
This paper presents the idea of creating cells while reducing part-level sequence-dependent setup time in general cellular manufacturing systems (CMS). Setup time reduction in CMS has gained modest attention in the literature. This could be attributed to the fact that the fundamental problem in cell formation in CMS has been mainly related to material handling and machine utilization while setu...
The CH3NH3PbI3 is one of the most widely used and famous lead halide perovskite absorber layer for using in perovskite solar cells. One of the ways to deal with the instability problem of this perovskite structure in environmental condition is bromide doping in this composition. In this work, the structural and optical properties of the bromide doped CH3NH3PbI3 absorber layers were studied as w...
This paper presents the design parameters for a single junction In0.5Ga0.5P solar cell using Silvaco ATLAS tool. Design parameters include thickness and doping concentration of the window, emitter and absorber layers. According to the simulation results, the absorber layer has the greatest effect on cell efficiency, and the emitter and window layers are in second and third positions, respective...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
The repeated exposure of a normal cell to carcinogenic agents may lead to its mutation, which changes into a cancer cell. In this case, the structure and function of the cells would alter, and they do not act normally. Chemicals, sun exposure, shortwaves, viruses, and bacteria play a significant role in cancer. Among the infectious and bacterial agents causing cancer, Helicobacter pylori (H. py...
In a dye-sensitized solar cell (DSSC), the amount of light absorption dependson the design of the pigments, which determines the strength of light absorption and theoptical range of the cell. In this paper, we have constructed and studied two fairly similarpattern of DSSCs in structure. The thickness of TiO2 used for both cells is taken to be 2μm. We have used an industrial N719 dye for one of ...
