background: a lot of investigations exist on the biological effects of radiofrequency and microwave radiation however only a few studies have considered non-carcinogenic exposure to radiations specifically from mobile phones. objectives: to introduce some subjective neurological symptoms in mobile phone users. materials and methods: in this cross-sectional descriptive study conducted from march...

testicular germ-cell tumors are the most common malignancy among men aged 20-40 years, and 60 percent of them are seminomas. these tumors are now an important socio-economic problem, considering their growing incidence. thus we undertook to evaluate the results of curative irradiation in our testicular seminoma patients and compare them to literature results considering the use of cobalt-60 sys...

increased number of mast cells at the site of infection is widely regarded as important host defense against parasites. the kinetics of mucosal mast cells and connective tissue mast cells responses were studied in the intestines of 68 female cflp mice infected with 100 schistosoma mansoni cercariae. the number of mucosal mast cells and the connective tissue mast cells increased from week 3 and ...

giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

dear editor-in-chief a 28 yr male was presented in october 2015 at medicine outpatient department, safdarjung hospital, new delhi- india with generalized weakness, fever and cough for preceding 15 days. clinicoradiologic examination revealed pallor, firm, non-tender splenomegaly measuring 13.7 cm and hepatomegaly (liver span - 16.9 cm). however, no lymphadenopathy was found.

dendritic cells (dcs) are professional antigen presenting cells that have a potential role in the initiating of immune responses. the cell vaccination is a new strategy in treatment of infectious diseases and cancers. in this study, we have generated monocyte-derived dendritic cells of lymphoma patient's peripheral blood mononuclear cells then; these cells were used as vaccine in lymphoma patie...

mycoplasma and ureaplasma species are the most serious contaminants of cell cultures and this remains one of the major problem encountered in biological research using cell cultures. the aim of this study was to investigate the rate of mycoplasma and a total of 100 different cell culture specimens including, r228, hela, vero, mdck, l20, rd and hep2 were collected. then the specimens were invest...

zinc has an important role in skin health and its deficiency reduces immunity. to evaluate levels of zinc in squamous cell carcinoma (scc) and basal cell carcinoma (bcc) of skin, we studied 44 bcc and 38 scc cases together with 33 controls. blood samples were taken and after separation of serum, levels of zinc, albumin and total protein were measured by atomic absorption, albumin kit and reflec...

introduction : arsenic trioxide (as2o3) causes antitumor effects by various mechanisms, including degradation of pml-rara in the acute promyelocytic cells, growth inhibition and induction of apoptosis. however, the precise mechanisms of these processes remain incompletely understood. the purpose of this study was to evaluate the effects of arsenic trioxide on cell growth, cell cycle regulation ...

background ecstasy or 3-4, methylenedioxymethamphetamine (mdma), as an amphetamine derivate, could lead to learning and memory impairment. objectives as the hippocampus is responsible for learning and memory, herein we evaluated acute and chronic effects of mdma on the structure of the hippocampus. materials and methods male wistar rats (200-250 g) received single or multiple injections of mdma...
