Using oligonucleotide synthesis techniques, we generated Escherichia coli rrnB P1 (rrnB1p according to the nomenclature of B. J. Bachmann and K. B. Low [Microbiol. Rev. 44:1-56, 1980]) promoter fragments containing single base substitutions, insertions, deletions, and multiple mutations, covering the whole length of the promoter including the upstream(More)
The role of ovarian hormones and nitric oxide (NO) on seizure and their interaction have been widely investigated. The present study carried out to evaluate the effect of chronic administration of L-arginine (LA) and L-NAME (LN) on pentylenetetrazole (PTZ) induced epilepsy in ovariectomized (OVX) and naïve female rats. Fourty-eight female rats were randomly(More)
OBJECTIVE To investigate the effects of soy extract on pentylenetetrazol (PTZ)-induced seizures in ovariectomized (OVX) rats. METHODS Female Wistar rats were randomly divided into 4 groups (n=15 in each group) as follows: sham-operated, OVX, low-dose soy (LDS) and high-dose soy (HDS). The rats in each group were divided into two subgroups and received(More)
Transcription of SSA1 (formerly YG100), a member of the hsp70 gene family in Saccharomyces cerevisiae, increases dramatically upon heat shock. An expression vector in which the promoter of SSA1 is fused to the Escherichia coli galactokinase gene (galK) was constructed and transformed into a galactokinase-deficient yeast strain. The transformants grew on(More)
BACKGROUND Essential oil of Pimpinella anisum L. Apiaceae (anise oil) has been widely used in traditional Persian medicine to treat a variety of diseases, including some neurological disorders. This study was aimed to test the possible anti-seizure and anti-hypoxia effects of anise oil. METHODS The effects of different concentrations of anise oil were(More)
OBJECTIVES Silver nanoparticles (Ag-NPs) are used widely in bedding, water purification, tooth paste and toys. These nanoparticles can enter into the body and move into the hippocampus. The aim of this study was to investigate the neurotoxicity of silver nanoparticles in the adult rat hippocampus. MATERIALS AND METHODS 12 male Wistar rats were randomly(More)
Dark neurons are seen in neurosurgical biopsies, experimental ischemia, hypoglycemia, and epilepsy. This study was aimed to investigate probable damage of amygdala due to pentylenetetrazol (PTZ)-induced acute seizures in rat. Male Wistar rats were divided into control, sham, and PTZ groups. EEG recordings were performed before and after the PTZ injection in(More)
Different wound dressings with antibacterial property have been surveyed and one among them is bacterial cellulose (BC). Since the BC does not have antibacterial property, the biologically produced silver nanoparticles (SNPs) were impregnated into the BC. For the BC production, Hestrin–Schramm broth was used. Formation of the BC was proven by enzymatic(More)
