Abstract
Although sewage water (SW) is a source of nutrients, it also causes heavy metal accumulation in soil; especially, lead (Pb+) contamination of soil is a serious concern in agriculture. Soil contaminants limit the bioavailability of nutrients to plants. So, they affect plant growth and produce quality. Therefore, a pot experiment was conducted to investigate the effect of zeolite soil amendment on the accumulation of Pb+ in tomato crop grown with SW irrigation. The pot media of SW-irrigated plants was amended with different concentrations of zeolite, viz., 0.75%, 1.50%, and 2.25%. The results showed that the application of 0.75% zeolite increased leaf area, plant height, fruit number, and plant fresh and dry biomasses by 37%, 17%, 14%, 24%, and 7% compared to freshwater irrigation. Moreover, the lowest zeolite dose also led to higher chlorophyll content (68.02 SPAD) compared to SW-irrigated plants (55.13 SPAD). Similarly physiological traits, such as A, gs, and E, were higher (17.68 µmol m-2 s-1, gs 0.28 mmol m-2 s-1, and 7.88 mmol m-2 s-1, respectively) in 0.75% zeolite-treated plants than in SW-irrigated plants (12.99 µmol m-2 s -1, 0.19 mmol m-2 s-1, and 7.00 mmol m-2 s -1, respectively). On the contrary, a reduced level of hydrogen peroxide and malondialdehyde and decreased activity of antioxidant enzymes were observed in low-dose zeolite applied plants. Zeolite reduced Pb+ accumulation in tomato plants as compared to SW-irrigated plants, whereby Pb accumulation in the fruits of SW-irrigated plants was 80% more than those of zeolite + SW-treated plants. Conclusively, this study has revealed the improvement in morphological and physiological growth attributes of the SW-irrigated tomato plant in response to zeolite application.

Abstract
The effect of carboxymethyl cellulose [(1%) CMC] was evaluated on mango fruits under storage at 20 ± 1 °C for 20 days. The CMC coating noticeably reduced weight loss and disease incidence. Application of CMC delayed climacteric peak of ethylene and respiration rate with significantly reduced relative ion leakage, malondialdehyde, superoxide anion and hydrogen peroxide content. The treated mangoes showed significantly lower L*, a*, b* and total carotenoids. The CMC treatment reduced the increase in cellulase, pectin methylesterase and polygalacturonase activity that delayed softening of mango fruits. In addition, activities of peroxidase, catalase, ascorbate peroxidase and superoxide dismutase were substantially higher in CMC-treated mango fruits. The treated fruits showed significantly lower soluble solids and higher titratable acidity which thereby reduced the ripening index of mangoes. In conclusion, CMC treatment could be considered a potential pre-storage treatment to delay postharvest ripening and to conserve the eating quality of ambient stored mango fruits.

Abstract
This study tested a novel combination of hydrocolloid gum arabic (GA) and carboxymethyl cellulose (CMC) to extend postharvest life of tomatoes. For this purpose, tomato fruits were coated with GA 10%, CMC 0.5% and GA 10% + CMC 0.5%, and stored for 20 days at 20 °C and 90 ± 2% RH. Application of biocomposite hydrocolloid coating reduced physiological weight loss, respiration rate, ethylene production, decay percentage and stress markers viz. malondialdehyde and hydrogen peroxide. Biocomposite hydrocolloid coating inhibited change in bioactive compounds (phenolics, ascorbic acid, and lycopene), color, organic acids, soluble sugars and up-regulated enzymatic ROS scavenging mechanism in tomato fruit more than GA or CMC coating. Moreover, biocomposite coatings delayed senescence by reducing activity of cell wall degrading enzymes and maintaining cell wall fractions. Conclusively, the biocomposite coating based on GA and CMC was superior to their individual coating in prolonging ripening phase, delaying senescence and increasing the acceptability of tomato fruits for longer duration.

Abstract
The effect of Aloe vera (AV) gel coating was studied on antioxidant enzymes activities, oxidative stress, softening and associated quality attributes of persimmon fruits. The fruits were coated with 0 and 50% AV-gel coating and stored for 20 days at 20 ± 1 ºC. AV-gel coated fruits exhibited considerably less weight loss, hydrogen peroxide level, electrolyte leakage and malondialdehyde content. AV-gel coated fruits had significantly higher ascorbate peroxidase, peroxidase, superoxide dismutase and catalase activities. In addition, AV-gel coating suppressed pectin methylesterase, polygalacturonase and cellulase activities and showed higher ascorbic acid, DPPH scavenging antioxidants and phenolics, and lower sugars and carotenoids. To the best of our knowledge, these results are the first evidence that AV-gel coating modulates the activities of cell wall degrading enzymes to delay ripening in climacteric fruits. So, AV-gel coating prohibited the onset of senescence by activating enzymatic antioxidant system, accumulating bioactive compounds and suppressing cell wall degradation.

Abstract
Nitrogen (N) is a macronutrient desired by crop plants in large quantities. However, hiking fertilizer prices need alternative N sources for reducing its requirements through appropriate management practices. Plant growth promoting rhizobacteria (PGPR) are well-known for their role in lowering N requirements of crop plants. This study assessed the impact of PGPR inoculation on growth, allometry and biochemical traits of chili under different N doses. Two PGPR, i.e., Azospirillum 'Er-20' (nitrogen fixing) and Agrobacterium 'Ca-18' (phosphorous solubilizing) were used for inoculation, while control treatment had no PGPR inoculation. Six N doses, i.e., 100, 80, 75, 70, 60 and 50% of the N required by chili were included in the study. Data relating to growth traits, biochemical attributes and yield related traits were recorded. Interaction among N doses and PGPR inoculation significantly altered all growth traits, biochemical attributes and yield related traits. The highest values of the recorded traits were observed for 100% N with and without PGPR inoculation and 75% N with PGPR inoculation. The lowest values of the recorded traits were noted for 50% N without PGPR inoculation. The PGPR inoculation improved the measured traits compared to the traits recorded noted in same N dose without PGPR inoculation. Results revealed that PGPR had the potential to lower 25% N requirement for chili. Therefore, it is recommended that PGPR must be used in chili cultivation to lower N requirements.

Abstract
Recent postharvest studies have shown that adding an antioxidative agent in a polysaccharide-based edible coating reduces postharvest losses and extends the shelf life of a coated fruit. Therefore, the effect of addition of ascorbic acid (AA, 1%) in chitosan-based coating (CH, 1%) on strawberry fruits under cold storage conditions at 4 ± 1 °C and 85 ± 5% RH was investigated for 15 days. It was observed that addition of AA in CH coating reduced weight loss, decay percentage, malondialdehyde content and hydrogen peroxide compared to CH alone. The combined CH + AA application also suppressed fruit softening by reducing cell wall degrading enzymes (i.e. polygalacturonase, cellulase and pectin methyl esterase) activities. In addition, AA incorporation catalyzed ROS scavenging enzymes (i.e. ascorbate peroxidase, catalase, peroxidase and superoxide dismutase) activities. CH + AA treatment also maintained fruit quality by conserving higher total soluble solids, titratable acidity, ascorbic acid content, total phenolics and antioxidant activity. Sensory quality (color, taste, glossiness and overall acceptability) of fruits coated with CH + AA treatment was also stable during storage. Conclusively, the combined CH + AA application is an effective approach to maintain the postharvest quality of strawberry fruits under cold storage.

Abstract
The effect of gum arabic (GA) coating was studied on apricot fruit at 20 ± 1°C for 8 days. GA coating substantially reduced weight loss, disease incidence, malondialdehyde concentration, and hydrogen peroxide compared to the control. GA coating resulted in significantly higher total phenols, ascorbic acid, and antioxidant activity in contrast to the control. GA coating also suppressed cellulase, pectin methylesterase, and polygalacturonase activity in contrast to the non-coated fruit. In addition, GA-coated apricot fruit had substantially higher catalase, peroxidase, ascorbate peroxidase, and superoxide dismutase enzymes activities in contrast with the control. Similarly, GA coating inhibited soluble solids content increase and inhibited the reduction in titratable acidity in coated fruit. The fruit coated with GA coating also had significantly better sensory and overall eating quality compared to the control apricots. In conclusion, GA could be considered an appropriate edible coating for quality conservation of apricots. PRACTICAL APPLICATIONS: Apricot is a well renowned and nutrients rich fruit. However, apricot has comparatively short shelf life potential due to its susceptibility to rapid senescence and deterioration under ambient conditions. GA is an eco-friendly and biodegradable coating which is considered relatively cheap as compared with other coating types. In our present work, application of gum arabic [GA (10%)] edible coating maintained significantly higher quality of harvested apricot fruit as compared with the control. The outcomes of the present work are of global significance with respect to apricot industry. So, GA coating could be considered an appropriate edible coating for quality conservation of the harvested apricot fruit.

Abstract
The application of edible coatings is an efficient way to reduce mass loss and to conserve the quality of a coated fresh produce during postharvest storage. In the present research, the impact of carboxymethyl cellulose [CMC (1%] coating was studied on 'Kinnow' mandarins during cold storage at 5 ± 1 °C for 30 days. Results showed that CMC treatment substantially suppressed chilling injury symptoms, disease incidence, fresh weight loss, malondialdehyde content, hydrogen peroxide and electrolyte leakage compared with control. The CMC coated 'Kinnow' mandarins showed markedly higher ascorbate peroxidase, peroxidase, superoxide dismutase and catalase enzyme activities compared to control. The treatment of 'Kinnow' mandarins with CMC also suppressed the increase in total soluble solids, ripening index and showed substantially higher titratable acidity, ascorbic acid, total phenolics content, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity along with better sensory quality in contrast with uncoated fruits. In conclusion, CMC coating could be an effective approach for the chilling injury reduction and quality maintenance of harvested 'Kinnow' mandarin fruits during cold storage.

Abstract
BACKGROUND Hydronephrosis in children is a common congenital urologic problem with pelviureteric junction obstruction being its most common cause. This study was conducted to evaluate the outcome of pyeloplasty for congenital pelviureteric junction obstruction in children. METHODS This study was conducted in department of Paediatric Surgery, Quaid-e-Azam Medical College/Bahawal Victoria Hospital, Bahawalpur from July 2008 to December 2010. A total of 50 patients diagnosed on ultrasonography and intravenous urogram as having PUJ obstruction were included. Patients with history of previous repair were excluded. Both Dismembered (Anderson Hynes) and Non-dismembered (Flap procedures) pyeloplasties were performed depending upon the size of pelvis and degree of dilatation. Initial follow-up was after 1 week, then after 15 days and then monthly for 3 months. Minimum follow-up period was 6 months and maximum 15 months. At three month, excretory urography was obtained to assess the function of that particular renal unit. RESULTS Lumbar pain and flank mass were the commonest presenting complaints. Thirty-six (72%) patients were male. Left sided obstruction was in 32 (64%) cases, right-sided in 15 (30%), and 3 (6%) cases were bilateral. Common post-operative complications were urinoma formation and re-stenosis in two cases each. There was also no gross difference of outcome in pyeloplasty whether done with or without double-J (DJ) stents. Moreover, dismembered pyeloplasty resulted in better outcome. CONCLUSIONS Open pyeloplasty is the "Gold Standard" treatment option for congenital pelviureteric junction obstruction. The use of DJ Stents is not necessary in every repair.

Abstract
Objective: To compare the complications rate of percutaneous nephrostomy and double J ureteral stenting in the management of obstructive uropathy. Methodology: Total number of 300 patients of age 20-80 years who underwent JJ stenting or percutaneous nephrostomy for obstructive uropathy were included in this study. Patients were divided in two groups i.e. A & B. In group A, 100 patients who underwent double J ureteral stenting while in group B, 200 patients who underwent percutaneous nephrostomy tube insertion were included. The stent was inserted retrograde by using cystoscope, under mild sedation or local anesthesia. While the percutaneous nephrostomy was done under ultrasound guidance by using local anesthetic agent. Complications were noted in immediate post-operative period and on follow up. Results: Majority of the patients were between 36 to 50 years of age with male to female ratio was 2.6:1. The most common cause of obstructive uropathy was stone disease i.e. renal, ureteric or both. Post DJ stent, complications like painful trigon irritation, septicemia, haematuria and stent encrustation were seen in 12.0%, 7.0%, 10.0% and 5.0% patients respectively. On the other hand, post-PCN septicemia, bleeding and tube dislodgment or blockage was seen in 3.5%, 4.5% and 4.5% respectively. In this study, overall success rate for double J stenting was up to 83.0% and for percutaneous nephrostomy (PCN) was 92.0% (p<0.0001). Conclusion: Percutaneous nephrostomy is a safe and better method of temporary urinary diversion than double J stenting for management of obstructive uropathy with lower incidence of complications.

Abstract
OBJECTIVE To determine the outcome of delayed end-to-end anastomotic urethroplasty in blind post-traumatic stricture of posterior urethra at our setup. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Department of Urology and Renal Transplantation, Quaid-e-Azam Medical College/Bahawal Victoria Hospital, Bahawalpur, from January 2009 to June 2011. METHODOLOGY Adult patients with completely obliterated post-traumatic stricture of posterior urethra ≤ 2 cm were included in the study. Patients with post-prostatectomy (TUR-P, TVP) stricture, stricture more than 2 cm in size or patients of stricture with neurogenic bladder and patients with any perineal disease were excluded from the study. Retrograde urethrogram and voiding cysto-urethrogram was done in every patient to assess stricture length and location. Stricture excision and delayed end-to-end anastomosis of urethra with spatulation was performed in every patient. Minimum followup period was 6 months and maximum 18 months. RESULTS There were 26 cases with road traffic accident (indirect) and 14 had history of fall/direct trauma to perineum or urethra. Majority of the patients (57.5%) were between 16 to 30 years of age. Twelve (30.0%) patients developed complications postoperatively. Early complications of wound infection occurred in 01 (2.5%) patient. Late complications were seen in 11 (27.5%) patients i.e. stricture recurrence in 7 (17.5%), erectile dysfunction in 2 (5.0%), urethrocutaneous fistula and urinary incontinence in one patient (2.5%) each. Success rate was 70.0% initially and 87.5% overall. CONCLUSION Delayed end-to-end anastomotic urethroplasty is an effective procedure for traumatic posterior urethral strictures with success rate of about 87.5%.

Abstract
BACKGROUND Metabolic Syndrome is a group of factors that predispose to cardiovascular diseases. The prevalence of metabolic syndrome is rising rapidly. Recently, a few studies have suggested that lower thyroid function in the reference range may be associated with metabolic syndrome, but the issue remains unsettled. We aimed to elucidate the relationship between thyroid function and components of metabolic syndrome in a sample of euthyroid Pakistani population. METHODS This analytical, cross-sectional study was conducted at the Department of Physiology, University of Health Sciences, Lahore, Pakistan, and extended over a period of 12 months. It included 100 subjects with metabolic syndrome in the study group and thirty subjects without metabolic syndrome in the control group with age ranging 45-55 years. Both groups had normal thyroid function. After a detailed history and clinical examination, fasting blood was analysed for glucose, triglycerides, high density lipoprotein-cholesterol along with thyroid-stimulating hormone (TSH) and free thyroxine. RESULTS Serum TSH was significantly higher in study group than in control group (p = 0.040). Serum free thyroxine values of study group were slightly but not significantly lower than those of control group. Serum TSH correlated significantly and positively with serum triglycerides in all subjects and with waist circumference and diastolic blood pressure in men. Serum TSH showed a positive and linear relationship with the number of components of metabolic syndrome (p = 0.016) in all subjects. CONCLUSION High-normal TSH is associated with metabolic syndrome and its components. There may be increased risk of cardiovascular diseases with high-normal TSH levels.

Abstract
A 13-year-old Saudi boy was referred to the paediatric endocrinology clinic for evaluation of rapidly progressive goitre with weight loss of 6 months duration. A clinical diagnosis of possible thyroid malignancy was made. On exploration the mass was found to be tuberculous in origin, attached to the thyroid gland, and responded to partial excision and anti-tuberculous chemotherapy. Tuberculosis should be considered in the differential diagnosis of anterior midline neck masses.

Abstract
Sheathed microfilariae (mean length 278 +/- 10 microns SEM; mean width 7.2 +/- 0.8 microns) were detected in the blood of 7/14 housed camels (Camelus dromedarius). Microfilaraemic camels of either sex were inappetent, lethargic, reluctant to move and exhibited weakness in the hind limbs; some remained in sternal recumbency. Cardiac disorders, orchitis and skin nodules were conspicuously absent. The microfilariae showed a biphasic pattern in the blood that peaked at 20:00 and plateaued between 04:00 and 06:00. Adult filarial worms were recovered from the mesenteric and femoral arteries. Marked clinical improvement within 1-2 weeks was seen in three camels treated at 10:00 with a single subcutaneous injection of 0.2 mg/kg of ivermectin. These camels became amicrofilaraemic 2-5 days after treatment and remained so for the length of the observation period (133 days). Treatment of two camels at the time of high microfilaraemia (06:30) resulted in adverse reaction and death.
