objective: helicobacter pylori has a well-established role in the development of gastric cancer. in vitro studies reveal increased proliferation of the gastric mucosa in the presence of h. pylori infection. it has been also shown that production of some cytokines, such as interleukin-1 beta (il-1b) is increased in h. pylori infection. in addition, il-1b increases proliferation of gastric epithe...

conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...

background: luteinizing hormone (lh) was secreted by the stimulating cells of the testes and ovaries in the anterior pituitary gland. the application of this hormone is in the treatment of men and women with infertility and amenorrhea respectively. m aterials and methods: in the present study the alpha and beta subunits of human lh gene were cloned into the pegfp-n1 expression vector and produc...

background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...

objective: glioblastoma multiforme (gbm), one of the most common and aggressive malignant brain tumors, is highly resistant to radiotherapy. numerous approaches have been pursued to find new radiosensitizers. we used a picogreen and colonogenic assay to appraise the dna damage and cell death in a spheroid culture of gbm cells caused by iodine-131 (i-131) beta radiation in the presence of topote...

Osteopontin also known as bone sialoprotein (BSP). Osteopontin role as a linking protein. it is an extracellular structural protein and therefore an organic component of bone. Osteoprontin (OPN) binds to several integrin receptors containing α4β1, α9β1, and α9β4 expressed by leukocytes. These receptors have been well-stable to function in cell adhesion, migratio...

results apoptosis induced by pa in ins-1 cells was significantly resolved after liraglutide treatment. simultaneously, autophagy was enhanced with the treatment of pa and liraglutide. conclusions: liraglutide appears to protect ins-1 cells from apoptosis ffa-induced by promoting autophagy. conclusions these findings provide a novel role for glp-1 analogue in preventing or treating with t2d. obj...
