Rats were exposed to vinyl chloride monomer gas (VCM) in a closed recirculating system. The rate at which VCM was removed from the system via metabolism was determined for rats exposed to initial concentrations of VCM ranging from 50 to 1167 ppm. Upon exposure to initial concentrations of 50 to 105 ppm, the rate of metabolism was 8.04 plus or minus 3.40 x 10(-3) min-1. Upon exposure to initial ...

Furfural is being added to kerosene to check the adulteration of gasoline/high speed diesel oil. The possibility of a co-exposure of furfural and kerosene and the ability to exhibit the toxic effects of such a mixture were examined in view of the toxicity potential of the two alone and in combination with each other. A single inhalation exposure of rats to furfural was fully tolerated up to a c...

This study evaluated the role of gibberellic acid [GA 3 ; (0, 100, 200, and 300 ppm)] in modulation growth, physiology, yield, quality traits two varieties (BARI Mung-6 BARI Mung-8) mungbean ( Vigna radiata L.). Irrespective Mung-8), ppm GA differentially modulated tested parameters (relative water content, RWC; photosynthetic pigments: chlorophyll a, b, carotenoids; growth parameters: fresh dr...

background: volatile organic compounds (vocs), including carcinogens and toxic compounds, are produced in petrochemical industries. we undertook this study in order to study workers’ respiratory exposure to different voc concentrations and compare the results with the urinary levels of its metabolites and study the correlation between them in petrochemical industries. materials and methods: exp...

Cattle drinking water is a source of on-farm Escherichia coli O157:H7 transmission. The antimicrobial activities of disinfectants to control E. coli O157:H7 in on-farm drinking water are frequently neutralized by the presence of rumen content and manure that generally contaminate the drinking water. Different chemical treatments, including lactic acid, acidic calcium sulfate, chlorine, chlorine...

zno thin film of 80 nm thickness was deposited by the sol-gel spin coating method on sio2/si substrate and subsequently post-annealed at 500°c with a flow of oxygen for 60 min. crystallographic structure of the sample was characterized by x-ray diffraction (xrd) method while a field emission scanning electron microscope (fesem) was used to investigate the surface physical morphology and chemica...

OBJECTIVES This study sought to assess the impact of permanent pacemaker (PPM) implantation on clinical outcomes among patients undergoing transfemoral transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI is associated with atrioventricular-conduction abnormalities requiring PPM implantation in up to 40% among patients treated with self-expanding prostheses. METHODS Between 2007 ...

the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2...

This study compared the ability of two sodium fluoride dentifrices, one containing 5,000 ppm fluoride (Prevident 5000 Plus) and the other 1,100 ppm fluoride (Winterfresh Gel), to reverse primary root caries lesions (PRCLs). A total of 201 subjects with at least one PRCL each entered the study and were randomly allocated to use one of the dentifrices. After 6 months, 186 subjects were included i...

The present experiment was carried out during Zaid 2021. In order to study the “Effect of Naphthalene Acetic Acid and Indole on Growth, Yield Quality Muskmelon (Cucumis melo. L). trail conducted at Biotechnology polyhouse, Department Horticulture, Naini Agriculture Institute Prayagraj. foliar spray two growth regulators like were separately different concentration (NAA @10ppm, 20ppm, 30 ppm, 40...
