BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

dementia is defined as significant acquired cognitive impairment in one or more cognitive domains that represents a significant decline from previous baseline and interferes with independence in daily activities. autoimmune dementia is a term that has been used to describe a steroid-responsive autoimmune disorder characterized by a rapidly progressive dementia with a fluctuating course. even co...

Thirty-six species o f wood-inhabiting microfungi have been assayed for cellulase, xylanase, mannanase and amylase activity by the use o f different test methods. The wood-degrading capabilities of the test organisms were previously known. Three o f the species were unable t o degrade birch wood. The other species represented three different degradation patterns, viz. I ) formation of soft rot ...

RAPD, RFLP, nuclear SSLP and chloroplast SSLP analyses were carried out to clarify the phylogenetic relationships among A-genome species of rice. In total, 12 cultivars of Oryza sativa (4 Japonica, 3 Javanica and 5 Indica), one cultivar of O. glaberrima, and 17 wild accessions (12 O. rufipogon, 2 O. glumaepatula, 1 O. longistaminata, 1 O. meridionalis and 1 O. barthii) were used. Their banding ...

hadula vassilinini (o. bang haas, 1927) was collected in crop fields' areas of khuzestan province, south-west iran. adults and genitalia are illustrated, with notes on bionomy and distribution. this is the first record of this species from iran with description of the previously undescribed female.

x-ray photoelectron and high resolution electron energy loss spectroscopic (xps-hreels) studies have shown that the adsorption of carbon dioxide at mg(100) surfaces at 80k is followed by a dissociative reaction leading to the formation of a metastable surface carbonate above 80k. the formation of a carbonate species is proposed to proceed through oxidation of c0 (g) by an active oxygen surface ...

One distinct concentration of copper ions was embedded into the silica matrix to xerogel form using copper source Cu(NO3)2∙3H2O. The xerogel samples were prepared with using hydrolysis and condensation reactions of TetraEthyl Ortho-Silicate (TEOS) by the sol-gel method. In this investigation, new molar ratio of H2</su...

Background and Aims: Candida albicans is the most prevalent opportunistic fungal species in the oral cavity. To date, several studies have been investigated the various factors associated with oral candidiasis. On the other hand, it has been proven that blood types antigens lead to some infectious factors. This study aimed to evaluate Candida albicans colonies in the saliva of dentistry student...
