introduction: kainic acid (ka) induces neuropathological changes in specific regions of the mouse hippocampus comparable to changes seen in patients with chronic temporal lobe epilepsy (tle). according to different studies, the expression of a number of genes are altered in the adult rat hippocampus after status epilepticus (se) induced by ka. this study aimed to quantitatively evaluate changes...

background: after radiation therapy (rt), some health hazards including dna damages may occur where melatonin can play a protective role due to free radical generation. on the other hand, serious accidental overexposures may occur during rt due to nuclear accidents which necessitate the need for study on exposure to high-dose radiations during treatments. objective: the aim of this study was to...

objective(s): the link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (gdm), but the underlying mechanisms for this phenomenon are still not clear. reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). some recent studies have provi...

background: the aim of this study was to detect the prognostic significance of survivin level and the expression of total p53 in acute lymphoblastic leukemia (all) and its correlation to patients' outcome. methods: sixty two children newly diagnosed with acute lymphoblastic leukemia were treated with chemotherapy and followed up for 2 years or until death. twenty apparently healthy volunteers w...

background: there are only four drugs for treating african trypanosomiasis, a devastating disease in sub-saharan africa. with slow discovery of better drugs, vaccination is viewed as the best method of control. we previously showed that antibodies to native trypanosoma brucei brucei tubulin inhibit the growth of trypanosomes in culture. here, we aimed to determine the effect of antibodies to ba...

abstract       background and objectives: more candida albicans strains are reported resistant to fluconazole in patients with aids, cancer and organ recipients. fluconazole resistance can be attributed to changes in pathways of sterol biosynthesis, mutation in or overexpression of erg11 and the expression of cdr1, cdr2, and mdr1. this study aimed to compare the expression of cdr1, cdr2, and md...

the mucus layer plays an important role as an intermediate for the protection of the gut against acidic chyme, digestive enzymes, and pathogens; in addition, it acts as a lubricant and facilitator of nutrient transportation. phytogenic compounds seem to promote intestinal mucus production. objectives: the current study was conducted to investigate the effects of low and high levels of energy an...

background: type ii diabetes is known as one of the most important, prevalent, and expensive diseases of mankind. late diagnosis and subsequent delayed initiation of treatment or surveillance of patients create a variety of problems for affected individuals. this has raised increasing concerns for public health authorities throughout the world. in the current study, we aimed to find a new appro...

b a c k g r o u n d  & aim: it is very helpful to classify and predict the clinical  category  of a sample based  on  its  gene  expression  profile.  this  study  was  conducted  to predict  tissues  of colorectal adenoma,  adenocarcinoma,  and  paired  normal  in  colon  based  on  microarray  data  using  nearest shrunken centroid method. methods   &  materials:    in  this  study,   the  co...

background calcium/calmodulin-dependent protein kinase iiα (camkiiα) may modulate the function of mu-opioid receptors by phosphorylation and therefore, be involved in development of morphine-induced analgesic tolerance. objectives the current study aimed to examine changes in gene expression of camkiiα in the lumbosacral cord and midbrain during induction of morphine analgesic tolerance. materi...
