A study was undertaken the effect of pretreatments and drying methods on quality parameters of tomato slices with respect to storage using two factors as treatments i.e. 5 pre-treatment levels (P1-Peeled by hot water dip blanching, P2-Peeled by hot brine dip blanching, P3-Unpeeled by hot water blanching, P4-Unpeeled by hot brine blanching, P5-Control- No peeled and no blanched) and 2 drying methods i.e. (D1-Tray drying, D2-Sun drying) with completely randomized design of factorial concept with three repetitions at Post Graduate Laboratory of Horticulture Department, College of Agriculture, Junagadh Agricultural University, Junagadh. The quality was evaluated on the basis of physicochemical (i.e. drying time (h) and moisture content (%) at 1, 20, 40, 60 and 80th day of storage. Result of study depicts that the pretreatment P2 i.e. peeling of tomato by hot brine dip blanching followed by tray drying (D2) recorded minimum (14.50 h) drying time and the minimum changes in moisture content (4.00%-6.54%) observed in treatment P1 at 1st to 80th day of storage, respectively.

Hallucinogenic fishes are fishes that can create hallucinations if their tissue is ingested. These incorporate certain types of fish found in a several parts of the tropics. The impacts of eating hallucinogenic fishes are rumored to be comparative in a few viewpoints to lysergic acid diethylamide (LSD) or dimethyltryptamine (DMT). The encounters may incorporate distinctive sound-related and visual hallucinations. This has offered ascend to the collective common name “dream fish” for hallucinogenic fish. Sarpa salpa, a species of sea bream, is commonly claimed to be hallucinogenic. In 2006, two men who apparently ate the fish experienced mind flights going on for a few days. It is misty whether the poisons are delivered by the fish themselves or by marine algae in their diet.

The effects of storage of Ogbona seed flour (Irivingia gabonensis and Irivingia excelsa), at ambient condition (30±20C, 65-74% RH) for 0-4 months on some physical characteristics were investigated. The samples were subjected to storage in air tight polyethylene bags for up to four months. Samples were removed at intervals of 0, 1, 2, 3 and 4 months for analysis. The chemical: proximate constituents, free-fatty acids and peroxide values; selected functional properties: water/oil absorption capacity, foam capacity and viscosity and sensory attributes of the samples were investigated. The result shows that there was no observable change in the chemical composition, selected functional and sensory properties of the two varieties of Ogbona seed flours when stored up to two months but decreased from third to fourth month during storage at ambient temperature. Therefore, storage at ambient temperature (30±20C, 65-74% RH) could extend the shelf life of the samples for up to two months in air-tight polyethylene bags of 0.7mm thickness without losing its quality characteristics.

Previous studies suggest that diets with more eggs than is recommended may be used as part of a healthy diet in some countries. However, whether quail egg diets could form part of such diet has not been explored. The aim of the present study is to evaluate the effect of quail egg consumption on serum markers of atherogenesis and hematological parameters in healthy volunteers. Thirty adult subjects participated in this study after ascertaining their baseline health status. They were fed 3 eggs per day and 8hourlyfor 30 days. They were evaluated for serum levels of cholesterol sub-fractions, AIP and hematological parameters at days 0, 10 and 30 after the consumption of quail eggs. At day10, serum levels of cholesterol sub-fractions (TG, HDL-C and LDL-C) were not significantly (p>0.05) different from the corresponding values at baseline. Serum levels of VLDL-C and calculated AIP significantly (p<0.05) decreased compared to the levels at baseline. At day 30, serum levels of HDL-C, TG and VLDL-C significantly (p<0.05) increased, while LDL-C and AIP significantly decreased. Also, total RBC, HB, PCV, MCV, MCH and MCHC were not significantly different from the levels at baseline. At day 30, RBC, PCV and HB significantly (p<0.05) increased compared to the levels at baseline, while MCV, MCH and MCHC were not significantly (p>0.05) different from the baseline values. Indeed, long-term consumption of quail egg may be associated with improvement in serum markers of atherogenesis and hematological parameters due to its varied nutrient constituents and their activities.

Background: Biopsy findings of percentage of positive biopsy cores, percentage of cancer volume, and maximum involvement of biopsy cores have been shown to have prognostic value and correlate with magnetic resonance imaging (MRI) findings of extracapsular extension and seminal vesicle invasion. The relationship of these prognostic biopsy factors to MRI findings of the presence of a dominant lesion, has not yet been investigated. Methods: Sixty-five patients with intermediate risk prostate cancer were included in a retrospective cohort. MRI was acquired using either 1.5 Tesla (T) with endorectal coil or a 3 T MRI unit. Findings of extracapsular extension, seminal vesicle invasion, and presence and number of dominant lesions were noted. T-test and Cox regression statistical analyses were performed. Results: Patients with one or more dominant lesions on MRI had a significantly higher mean percentage of positive biopsy cores (56.7% vs 39.8%, p=0.004), percentage of cancer volume (23.5% vs 14.5%, p=0.011) and maximum involvement of biopsy cores (62.9% vs 47.3%, p=0.027) than those without a dominant lesion on MRI. On multivariate analysis, only percentage of positive biopsy cores remained a statistically significant predictor for a dominant lesion on MRI (Hazard Ratio 1.06 [95% CI 1.01-1.12; p=0.02]), whereas prostate-specific antigen, clinical T-stage, Gleason score, percentage of cancer volume, and maximum involvement of biopsy cores were not significant predictors of a dominant lesion on MRI. Receiver-operator characteristic analysis was done and a cutoff value of >=50% was chosen for percentage of positive biopsy cores, >=15% for percentage of cancer volume, >=50% for maximum involvement of biopsy cores. Conclusion: Percentage of positive biopsy cores was found to be a significant predictor for the presence of a dominant lesion on MRI. This finding is hypothesis-generating and should be confirmed with a prospective trial.

Objective: To determine the diagnostic accuracy of Magnetic Resonance Imaging (MRI) to differentiate Benign and Malignant Parotid Gland Tumors taking histopathology as gold standard. Design: Cross sectional study. Place and duration of study: Department of Diagnostic Radiology, Lahore General Hospital, Lahore from January till July 2014. Methodology: 200 patients of age between 5 to 80 years of either gender with parotid gland swelling, having radiological evidence and clinical suspicion of parotid tumour like fixation to underlying skin, pain, facial palsy and cervical lymphadenopathy were taken. T1 and T2 plain and contrast enhanced 1.5 Tesla MRI unit using standard imaging coil was then carried out. Imaging was further evaluated for the presence or absence of benign or malignant parotid gland tumours using histopathology as a Gold standard. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of MRI were taken against the gold standard. Results: There were 170 males and 30 females having mean age of 40.27±15.04 and 40.12±12.15 years respectively. Sensitivity, specificity, positive predictive value and negative predictive value of MRI were 90.4%, 89.33%, 93.39% and 84.41% respectively. The diagnostic accuracy of MRI to differentiate benign and malignant parotid gland tumours was 90%. These results were taken against surgery histopathology as a gold standard. Conclusion: MRI is highly accurate in differentiating malignant & benign tumours of parotid glands and can be used as an adjunct to histopathology for pre-operative evaluation of the parotid gland tumours.

Purpose: The purpose of this study was to evaluate biological dose in single-field optimization (SFO) and multi-field optimization (MFO) intensity-modulated proton therapy (IMPT) plans for brain tumor patients that used a fixed relative biological effectiveness (FRBE) and those that used a variable RBE (VRBE). Materials and methods: SFO and MFO IMPT plans were planned by the Varian Eclipse treatment planning system for three brain tumor patients. Dose and linear energy transfer (LET) distributions for each plan were recomputed using an in-house fast Monte Carlo dose calculator system, and then biological dose distributions were calculated with a FRBE of 1.1 or with a previously published VRBE model. We then compared biological dose distributions obtained by the VRBE with those obtained by the FRBE. Results: Doses obtained by the VRBE for the gross tumor volume and clinical target volume in all plans were 1%-2% larger than those obtained by the FRBE. The minimum dose obtained by the VRBE for the brainstem in the SFO IMPT of one patient was 140% larger than that obtained by the FRBE, but the difference was only 5.3 cGy (RBE). The difference in maximum dose for the optic chiasm in the MFO IMPT of another patient was less than 3.2%, but the dose difference was 149.2 cGy (RBE). We also found that no major differences were seen between the biological dose differences in the SFO IMPT plans and those in the MFO IMPT plans. Conclusion: We could observe biological dose differences between the FRBE and the VRBE in the SFO and the MFO IMPT plans for brain tumor patients.

Background: Even with current standard treatment after variceal bleeding which includes combination of nonselective b-blockers and repeated endoscopic variceal ligation, the risk of rebleeding and mortality are high. Statins exhibit an antifibrotic effect and improves HVPG. We evaluated whether addition of simvastatin to carvedilol plus EVL therapy reduces variceal rebleeds or death in patients with cirrhosis. Method: Patients with a variceal bleed 5 to 10 days before were randomly assigned to groups A [carvedilol (n = 69)] or group B [carvedilol (maximum dose - 12.5mg), and simvastatin (40mg/day) (n = 65)]. Primary end points were variceal rebleeding or death. Secondary end points were new complications of portal hypertension and serious adverse effects of drugs. Results: During a mean follow-up of 49.05 ± 25.74 weeks, composite end point i.e. rebleeding or death developed in 23 patients (33.3%) in group A and 12 patients (18.5%) in group B [HR for simvastatin = 0.512; 95% CI: 0.254 – 1.030; p = 0.06]. In subgroup analysis by excluding patients of Child C class, 18 patients (34.6%) in group A and 7 patients (13.6%) in group B developed composite end point [HR for simvastatin = 0.369; 95% CI: 0.154 – 0.887; p = 0.026]. 17.4% and 15.4% patients in group A and B developed additional secondary complication [HR = 0.86; 95% CI: 0.345-2.161; p = 0.75). No simvastatin induced significant adverse effects were found. Conclusion: Addition of simvastatin to carvedilol and EVL may reduce the rebleeding and death in patients with less advance liver disease.

Treatments via the minor papilla is effective where the deep cannulation via the major papilla is impossible in such cases as [1] the Wirsung’s duct is inflammatory narrowed, bent or obstructed by impacted stones [2] pancreatic duct divisum (complete or incomplete) [3], maljunction of pancreatico-biliary union with stones [4], pancreatic stones in the Santorini’s duct. In [1,2] cases, the pancreatic juice flow via the major papilla decreases, while that of the minor papilla increases. Then the size of minor papilla and its orifice shows corresponding enlargement. This substitutional mechanism is an advantage when undertaking our new method. Since the pancreatic juice flow is maintained via the minor papilla in these cases, accurate and careful endoscopic skills are necessary to prevent pancreatitis due to the occlusion of the Santorini’s duct after this procedure. We have experienced 135 cases treated via minor papilla in these 27 years, so we would like to report about its safety and efficacy.

Haemophagocytosis is a dysregulated immune condition characterised by both inflammation and uncontrolled activation of macrophages and T-cells, which causes aberrant cytokine release, leading to cytokine storm [1] it can be primary or secondary, depending upon the etiology.
