The purpose of the present study was to find out the sources of mercury and arsenic pollution of water in the industrial area of Peshawar, the capital of Khyber Pakhtunkhwa, Pakistan. Samples of effluents, mud, and water were collected from the target area (industrial area of Peshawar), the area of water supply source, and from the less polluted area, the Lower Dir district, as the control. Hg was determined by the cold vapor generation technique, while arsenic was determined using the electrothermal atomic absorption technique. Data of the water from the industrial area were compared with that of the source area, control area, as well as with the WHO and some international drinking water quality standards. The results show that some parameters, i.e., TDS, DO, pH, and hardness, were more than the permissible limits. Textile and glass industries were found to be the major sources of Hg and As pollution. Downstream dilution of these contaminants was also observed. © 2012 Springer Science+Business Media B.V. Source

The main objective of the current study is to investigate the potential of Carica papaya leaves extracts against Dengue fever in 45 year old patient bitten by carrier mosquitoes. For the treatment of Dengue fever the extract was prepared in water. 25 mL of aqueous extract of C. papaya leaves was administered to patient infected with Dengue fever twice daily i.e. morning and evening for five consecutive days. Before the extract administration the blood samples from patient were analyzed. Platelets count (PLT), White Blood Cells (WBC) and Neutrophils (NEUT) decreased from 176 × 103/μL, 8.10 × 103/μL, 84.0% to 55 × 103/μL, 3.7 × 103/μL and 46.0%. Subsequently, the blood samples were rechecked after the administration of leaves extract. It was observed that the PLT count increased from 55 × 103/μL to 168 × 103/μL, WBC from 3.7 × 103/μL to 7.7 × 103/μL and NEUT from 46.0% to 78.3%. From the patient feelings and blood reports it showed that Carica papaya leaves aqueous extract exhibited potential activity against Dengue fever. Furthermore, the different parts of this valuable specie can be further used as a strong natural candidate against viral diseases. © 2011 Asian Pacific Tropical Biomedical Magazine. Source

Photo oxidative stress were applied to commonly consumed edible oil and fat i.e., animal fat (AF), vanaspati ghee (VG), sunflower oil (SFO), desi ghee (DG), rapeseed oil (RSO), soybean oil (SBO) as well as sea buckthorn seed oil (SB Seed oil) and sea buckthorn pulp oil (SB Pulp oil). The changes in their quality parameters i.e. free fatty acid (FFA), peroxide value (POV), beta-carotene and color (OD) were determined. Photo oxidative stress significantly (p < 0.05) increased the FFA, POV and OD, however, concentration of beta carotene decreased in all the samples with the increase in storage time. The Sea buckthorn oil was found to be more stable than other oils owing to the presence of tocopherol contents and β-carotene. Source

Race-specific resistance of wheat (Triticum aestivum L.) to yellow rust caused by Puccinia striiformis Westend. f.sp. tritici is often short-lived. Slow-rusting resistance has been reported to be a more durable type of resistance. A set of sixteen bread wheat varieties along with a susceptible control Morocco was tested during 2004-05 to 2006-07 in field plots at Peshawar (Pakistan) to identify slow rusting genotypes through epidemiological variables including final rust severity (FRS), apparent infection rate (r), area under disease progress curve (AUDPC), average coefficients of infection (ACI) and leaf tip necrosis (LTN). Epidemiological parameters of resistance were significantly (P < 0.01) different for years/varieties in three seasons, while variety × year interactions remained non-significant. Sequence tagged site (STS) marker, csLV34 analyses revealed that cultivars Faisalabad-83, Bahawalpur-95, Suleman-96, Punjab-96, Bakhtawar-93, Faisalabad-85, Shahkar-95 and Kohsar-95 possessed Yr18 linked allele. Faisalabad-83, Bahawalpur-95, Suleman-96, Punjab-96, Bakhtawar-93 and Faisalabad-85 were relatively more stable over 3-years where FRS, AUDPC and r values reduced by 80, 84 and 70% respectively compared to control Morocco. These six varieties therefore could be exploited for the deployment of Yr18 in breeding for slow rusting in wheat. Both FRS and ACI are suitable parameters for phenotypic selection. © 2009 Blackwell Verlag GmbH. Source
