Oyster mushroom is a group of food plants that are rich in protein, vitamins and minerals. The weakness this its high moisture content so it rots quickly when stored fresh conditions. Drying by using solar energy one the best options because sufficient quantity low cost. This study proposes dryer with three collectors 500 mm x 1254 each 4 rack. drying experimental sample 1 kg. model kinetics MM...

A previous study of six polychlorinated biphenyl (PCB) congeners showed that PCBs with four or fewer chlorines and ortho substitution stimulate uterine contraction frequency in vitro, whereas congeners with a greater number of chlorines or non-ortho substitution are inactive in vitro. We tested the hypothesis that PCB mixtures stimulate uterine contractions in a manner inversely related to the ...

Polychlorinated biphenyls (PCBs) are widespread persistent residual environmental pollutants, which affect seriously the growth and reproductive alterations in humans and animals. Aroclor 1254 is a commercial mixture of PCBs. Quercetin is a flavonoid, which acts on estrogen receptors and causes the development of estrogen-related diseases. In this paper, the primary cultured endometrial cells i...

The aim of this study was to apply RAPD technique to analyze the genetic variability among the Iranian CA-MRSA isolates.The RAPD amplification was implemented on 25 strains isolated from the anterior nares of 410 healthy children using four randomly selected oligonucleotide primers from the stocks available in our laboratory, including the primers 1254, GE6, OLP6 and OLP13 from our stock. The a...

In this study the mechanism of thyroid hormone reductions reported in rodents, following exposure to TCDD (Potter et al, 1983), PCBs (GrassIe and Biesmann 1982; Brouwer 1987) and polybrominated biphenyls (Gupta et al 1983), was investigated in rats at the level of the transport protein, transthyretin (TTR), using 3,4,3',4'-tetrachlorobiphenyl (TCB) as a model compound. Moreover, the effeets of ...

Dibenzo[a,l]pyrene (DBP) is one of the most potent bacterial mutagen and mammary carcinogens. When DBP (50 microM) was incubated with calf thymus DNA (300 microg/ml) in the presence of liver microsomes from beta-naphthoflavone (beta-NF)- or Aroclor 1254-treated rats, at least eight adduct spots were detected as analyzed by nuclease P1-enhanced 32P-postlabeling assay. DNA adduction was enhanced ...

INTRODUCTION New-onset postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery that has substantial effects on outcomes. The aim of this study is to analyze the risk factors in the pre, intra, and postoperative periods, and evaluate its impact on patients' outcome. METHODS In this prospective study, between March 2007 and February 2011, a total of 1254 patients wi...

Colon mucosal cells can catalyze the activation of precarcinogens to mutagenic metabolites without the intermediacy of intestinal bacteria as shown in a mutagenesis assay system composed of Salmonella typhimurium strain TA100 and the 9000 X g supernatant fraction of rat colon mucosal cells. Pretreatment of rats with beta-naphtoflavone increased the activation of 2-aminoanthracene 10- to 20-fold...
