Syed Mubashir Sabir,Syed Zulfiqar Ali Shah,Abida Afzal
Pakistan Journal of Nutrition , 2004,
Abstract: Chemical treatment, wax coating, oil dipping and different wrapping materials have significant role in extending the shelf life of apple. The present investigation was therefore, carried out to extend the shelf life of Banky cultivars of apple by applying the above mentioned treatments. In physical characteristics general appearance (color and shape of fruit), weight loss percentage and organoleptic evaluation were studied during storage. Chemical treatment, total soluble solids, pH, acidity, total sugar, reducing sugar and Vitamin C were analyzed after 15, 30, 45 and 60 days of storage. All the treatment had significant effect on the shelf life of fruits. However, Non-perforated polyethylene was reported superior to all other treatments. Non-perforated polyethylene materials proved very useful for reducing weight loss and shriveling and retained consumer acceptability even after 60 days of storage. Hydroxyquinoline and butter paper wrapping stood second and third positions after non perforated polyethylene wrapping.

American Journal of Plant Sciences (AJPS) , 2016, DOI: 10.4236/ajps.2016.76074
Abstract: Studies were initiated to explore the role of nucellus tissues and growth regulators in plantlets regeneration via somatic embryogenesis of Kinnow mandarin [Citrus reticulata L. (Blanco)]. Nucellus tissues were cultured on MS medium supplemented with different concentrations and combinations of auxins, cytokinins and malt extract for primary callus induction. The best response for primary callus induction (90%) was obtained when MS medium was supplemented with 5 mg/l 2,4-D and 500 mg/l malt extract. Best results for embryogenic callus induction (80%) were obtained in C8 medium. The induction of somatic embryos was highest when MS medium was supplemented with 1 mg/l BAP and maturation of somatic embryos occurred when MS medium was supplemented with 5 mg/l 2,4-D and 1 mg/l BAP. Maximum plantlets were regenerated (92%) from the somatic embryos on half strength MS medium with no hormones. The plantlets were successfully acclimatized in different potting mixtures and highest survival rate (100%) was achieved in potting mixture containing sand and peat moss (2:1).

Pakistan Journal of Nutrition , 2003,
Abstract: The present investigation was carried out for the estimation of sterol in edible fats and oils. Ten samples of vanaspati ghee which were most commonly available in the market were subjected to sterol estimation. The samples included Dalda, Tullo, Habib, Fauji, Kissan, ACP, Latif, Family, Zaiqa and Handi vanaspati. Dalda, Tullo and Habib vanaspati contained relatively less amount of cholesterol (10, 14 and 15 mg/g respectively) While, Fauji, Kissan, ACP and Latif vanaspati had the intermediate values of cholesterol (24, 25, 29 and 30 mg/g respectively). Family, Zaiqa and Handi vanaspati contained maximum amount of cholesterol (33, 37 and 40 mg/g respectively). Dalda vanaspati had the least (10 mg/g) while, Handi vanaspati had the highest (40 mg/g) amount of cholesterol. Among other samples butter and Haleeb Desi ghee contained the high amount of cholesterol (27, 7 mg/g respectively), while milk fat, beef tallow and fish fat were low in cholesterol content (3.5, 1 and 4 mg/g respectively). Bear fat had the immense quantity of cholesterol (80 mg/g). The sterol content of edible oils i.e. Corn (23 mg/g), Soybean (9 mg/g), Rapeseed (5 mg/g) and Coconut (0.8 mg/g) were reported less as compared to the sterol content of mustard oil (64 mg/g).

Pakistan Journal of Biological Sciences , 2003,
Abstract: The present work was done for the estimation of trace metals in eight samples of drinking water collected from springs, wells and taps of Bagh city and around. Springs and wells are open and can be approached by any contaminant. The concentrations of Pb, Cu, Ni, Mn and Zn in water samples were determined. The overall concentration of trace metals ranged from 0-7 ppm. The concentration of lead was found quite high (0-7 ppm). The maximum concentration of lead (7 ppm) was found in the Sample (5). The concentration of copper was also found high (0-4 ppm). The maximum concentration of copper (4 ppm) was recorded in Samples (2) and (5). The concentration of nickel, zinc and manganese were found small (0-3 ppm). Thus, the contamination of drinking water by Ni, Mn and Zn is less as compared to Pb and Cu. Physical analysis of water was carried out to assess the quality of water. Temperature was found between 18-230C for different samples. All samples were tested and found colorless, odorless and tasteless. PH was determined by pH meter and ranked from 5.5-7. Most of the samples were almost at neutral pH, however, sample (5) was reported acidic (pH 5.5).

Hanyu Li,Mubashir Syed,Yu-Dong Yao,Theodoros Kamakaris
EURASIP Journal on Advances in Signal Processing , 2009, DOI: 10.1155/2009/834527
Abstract: This paper investigates spectrum sharing issues in the unlicensed industrial, scientific, and medical (ISM) bands. It presents a radio frequency measurement setup and measurement results in 2.4 GHz. It then develops an analytical model to characterize the coexistence interference in the ISM bands, based on radio frequency measurement results in the 2.4 GHz. Outage performance using the interference model is examined for a hybrid direct-sequence frequency-hopping spread spectrum system. The utilization of beamforming techniques in the system is also investigated, and a simplified beamforming model is proposed to analyze the system performance using beamforming. Numerical results show that beamforming significantly improves the system outage performance. The work presented in this paper provides a quantitative evaluation of signal outages in a spectrum sharing environment. It can be used as a tool in the development process for future dynamic spectrum access models as well as engineering designs for applications in unlicensed bands.

The activity of antioxidative enzymes system is affected by salt stress, chlorophyll content (CHL), leaf relative water content (RWC), Na+ and K+ contents, their ratio and some oxidative stress indices were studied in leaves of ten bread wheat cultivarsSehar-06, Lu-26, NARC-09, BARC-09 and Pirsbak-09’(salt-tolerant) and Kaghan-94, Rohtas-90, Soughat-90, Shaheen-94 and Zardana-89’(salt-sensitive), grown under salinity treatments carried out in five levels (1 < dS·m-1 as control, 2, 4, 8, 16 dS·m-1) via sodium chloride. Under high salt potency significant increase for activities of antioxidant enzymes such as ascorbate peroxidase (APX) and guiacol peroxidase (GPX), occured in salt tolerant varieties. Meanwhile, under salinity condition the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and (GPX) in sensitive cultivar were lower than control. Regarding (APX) activity there was no significant difference between salinity and control situation. Under salt stress membrane stability index (MSI) of both cultivars were negatively influenced. Hydrogen peroxide (H2O2) content of salinity sensitive cultivars was higher than control. Salt tolerant varieties had more amounts of K+ content, K

Pakistan Journal of Nutrition , 2003,
Abstract: The meat consumed by the people is sold in the open market and even on the roadsides. Special attention was focused on the determination of selected essential/heavy metals in meat samples. For assessing daily environmental contamination, sixteen meat samples of four varieties (Fish, beef, mutton and chicken) were purchased from local market and different spots of Nalahs (ravine). The samples were analyzed for the estimation of trace metals such as Pb, Cu, Ni, Zn along with Ca, Mg and Fe. The overall concentration of Pb, Ni, Zn and Mn were found small (0-4 ppm). Among major elements Fe was found quite high (600-7000 ppm). The Ca (600-2000 ppm) and Mg (800-1300 ppm) levels were also higher. Fe was recorded higher in beef and mutton, Ca in fish and mutton and Mg in mutton, chicken and fish were comparatively noted high.

Cardiology Research and Practice , 2011, DOI: 10.4061/2011/656835
Abstract: Background. We evaluated the prevalence and clustering pattern of cardiovascular disease (CVD) related lifestyle factors and their association with CVD among patients with type 2 diabetes. We also examined the association of these factors with various socio-demographic characteristics. Methods. A total of 1000 patients with type 2 diabetes were interviewed in a cross-sectional, multi-center study in out-patient clinics in Karachi, Pakistan. Results. In this study 30.3% study participants had CVD. Majority of the patients were physically inactive and had adverse psychosocial factors. Forty percent of the study participants were exposed to passive smoking while 12.7% were current smokers. Only 8.8% of study subjects had none of the studied lifestyle factor, 27.5% had one, while 63.7% had two or three factors. CVDs were independently associated with physical inactivity, adverse psychosocial factors, passive smoking and clustering of two or three lifestyle factors. Physical inactivity was more prevalent among females and patients with no/less education. Proportion of adverse psychosocial factors were higher among females, elders and patients with no/less education. Clustering of these lifestyle factors was significantly higher among females, elderly and no/less educated patients. Conclusion. These results suggest the need of comprehensive and integrated interventions to reduce the prevalence of lifestyle factors. 1. Introduction Cardiovascular disease (CVD) is known to be the leading cause of mortality worldwide resulting in 17.1 million deaths, with 13 million deaths attributed to coronary heart disease and stroke alone; of these, more than 80% of deaths has occurred in low- to middle-income countries [1]. It is projected that by the year 2030, CVD-related mortality will rise up to 25 million, mainly from heart disease and stroke [1]. Similarly, global statistics on diabetes are also alarming, as the disease is rapidly increasing worldwide and future projections of its burden are reported to rise particularly in Pakistan and other developing countries [2, 3]. It is evident that diabetes is an independent risk factor for CVD, and people with diabetes are three to four times more likely to develop CVD [4, 5]. The development of CVD in diabetic patients is a cause of concern, as it is a major reason for hospitalization, premature morbidity, disability, and mortality [6, 7] which lead to an increased cost of care. It is reported that over 70% of the cost attributed to diabetes care is associated with its cardiovascular complications [6]. Lifestyle behaviors
