background; work-related musculoskeletal disorders (wmsds) may involve all parts of the body, and have been a worldwide problem. employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more wmsds because of high rate of repetitive motions. methods;the aim of this study to determine the prevalence of wmsds in women workers of an automobile...

The newly established ovarian cell line of Bombyx mori, DZNU-Bm-12 was tested for its susceptibility to homologous nucleopolyhedrovirus, BmNPV. The BmNPV was serially passaged in the cell line for five times along with the other four cell lines Bm-1, Bm-16 and Bm-17 which is established in our laboratory and Bm-5 is a widely used cell line. All the cell lines are susceptible to BmNPV. The overa...

In order to study the mechanism of etoposide (VP-16) resistance in human tumor cells and to assess the role of P-170 glycoprotein in VP-16 accumulation, we have examined the uptake and efflux of VP-16 in both sensitive and multidrug-resistant MCF-7 human breast and HL60 human promyelocytic leukemia cells. The drug-resistant cells, MCF-7/ADR and HL60/ADR, were selected for resistance to adriamyc...

contamination sites of pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in shiraz, iran. samples of raw and pasteurized milk were collected at six sites along the line. all milk samples were incubated at 7°c until the aerobic plate count had reached 10 6 -10 7 cfu ml-1. colonies were picked randomly and identified. no growth of gram negati...

Abstract: Background  and  Aims:  Huh-7  is  a  cell  line  that  was  derived  from  a  liver  tumor  of  a  Japanese  man.  Hepatocellular  carcinoma  (HCC)  is  considered  as  a  primary  liver  cancer.  Highly  resistant  tumor  to  treatment  which  causes  the  death  of  many  patients  annually.  Thus,  targeting  the  cancer  cells  by  using  a  new  method  could  be  effective  in...

objectives: 7-prenyloxycoumarins are a group of secondary metabolites that are found mainly in plants belonging to the rutaceae and umbelliferae families. this study was designed to evaluate and compare the cytotoxic and apoptotic activity of 7-prenyloxycoumarin compounds and herniarin on mcf-7, a breast carcinoma cell line. materials and methods: cells were cultured in rpmi medium and incubate...

Automobile sector forms the backbone of manufacturing sector. Vehicle assembly line is important section in automobile plant where repetitive tasks are performed one after another at different workstations. In this thesis, a methodology is proposed to reduce cycle time and time loss due to important factors like equipment failure, shortage of inventory, absenteeism, set-up, material handling, r...
