Background: Zinc has important effects on human health, especially on structural and functional activities of the immune system. This study was carried out to examine the in vitro cytotoxic effects of zinc on Raji cell line. Materials and Methods: The cell line was exposed to different concentrations of zinc followed by incubation (37°C, 5% CO2) at various time points (12 to 72 hrs).Viabil...

Background: Zinc has significant effects on structural and functional activities of many proteins and enzymes involved in biological activities, especially the regulation of immune-system. Symptoms of zinc toxicity include nausea/vomiting, fever, cough, diarrhea, fatigue, neuropathy, and dehydration. Further signs include growth retardation, altered iron function, anemia, copper deficiency, ...

BACKGROUND The cases of Plasmodium vivax malaria in Korea are mixed with long and short incubation periods. This study aims to define clinico-epidemiologic chracteristcs of Plasmodium vivax malaria in Korea. MATERIALS AND METHODS We selected the civilian cases infected with P. vivax malaria in Korea from the epidemiological investigation data of 2001 to 2010, whose incubation periods could be...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...

Of the problematic agents in the ecosystem, heavy metals have special importance because they are unabsorbable and have physiologic effects on living beings at low concentrations. This study has investigated the effect of silk worm cocoon on reducing mobility of zinc (Zn) and copper (Cu) for the first time. To this end, 5% cocoon adsorbent was added to the studied soil, which had been contamina...

A film-stack reaction field with a micropillar array using a motor stirrer was developed for the high sensitivity and rapid enzyme-linked immunosorbent assay (ELISA) reaction. The effects of the incubation time of a protein (30 s, 5 min, and 10 min) on the fluorescence intensity in ELISAs were investigated using a reaction field with different micropillar array dimensions (5-µm, 10-µm and 50-µm...

background: aflatoxin contamination of food and feed stuff is a serious health problem and significant economic concerns. in the present study, the inhibitory effect of candida parapsilosis ip1698 on mycelial growth and aflatoxin production in aflatoxigenic strains of aspergillus species was investigated. methods: mycelial growth inhibitions of nine strains of aflatoxigenic and non-aflatoxigeni...
