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.

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.

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.

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.

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.

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.

Effect of drying methods (sun-drying and cabinet oven drying) on the physicochemical properties and fatty acid composition of oils extracted from moringa seeds was investigated. Oil from the seeds was extracted using solvent (hexane) after drying. Drying increased the yield from 30.30-33.11%. The oil samples were less dense than water with specific gravities of 0.9032, 0.9075 and 0.9030 respectively. A significant difference exists in the moisture contents (0.11-0.21%); smoke point (202-2250C), flash point (310-3170C) and fire point (360-3690C). Sun-drying and cabinet oven drying brought about a decrease in the acid value (1.80-1.08mgKOH/g), saponification value (174.87-105mgKOH/g), Iodine value (16.10-13.90wijs) and peroxide value (11.24-2.3-Meq/kg). The decrease is an indication of quality improvement of the oils. More unsaturated fatty acids were present in the samples between 76.61% and 81.66%. Oleic acid was predominant (44.92% raw, 45.71% sundried and 43.60% cabinet oven dried). Sun-drying and cabinet oven drying did not have much significant effect on the physical, chemical and fatty acid compositions of the oil. The results obtained from this study showed that the three oil samples are good as edible oil and for commercial purpose.

This study was aimed at producing a high nutritious food that will meet the nutritional requirements of consumers. Blends of malted red sorghum and defatted soybeans flour were processed and the resulting flours were formulated at ratios of 100:00; 95:5; 90:10 and 80:20 (malted red sorghum: defatted soybeans flour). The resulting products were subjected to antinutrients and minerals properties determination. The results obtained showed that the antinutrients decreased linearly with increase in the mineral elements. Antinutrients in the blends decreased from 2.25-1.80mg/g (oxalate); 2.45-2.16mg/g (phytate); 14.16-9.26g/100g (Alkaloids); 2.12-1.69/100g (saponin) and 0.18-0.13mg/g (Tannin). A percentage increase of 12.6% (sodium); 10.8% (calcium); 9.5% (potassium); 3.7% (magnesium) and 14.1% (Iron) was recorded as the quantity of defatted soybeans flour increased in the blends. The low levels of antinutrients in the blends produced make them safe and suitable for human consumption. Substitution of malted red sorghum with 20% defatted soybean flour showed a remarkable improvement in the mineral contents of the diets

This study was carried out to evaluate the effect of pretreatments and drying methods on the chemical quality and microbial density of wild edible oyster mushroom. The mushroom samples were pretreated by steeping in 0.5% citric and sodium metabisulphite at room temperature for 10 minutes before being subjected to sun and cabinet drying until a constant weight was reached. The dried samples including the control samples (Samples not pretreated with chemicals) were evaluated for proximate, mineral composition and microbial density. The proximate analysis (protein, ash, fat, moisture and fibre) showed that untreated mushroom samples (both sun and cabinet dried) had the overall best results followed by samples pretreated with 0.5% sodium metabisulphite while samples pretreated with 0.5% citric acid had the lowest values. The mineral analysis (calcium, sodium, magnesium and potassium) of the mushroom samples followed the same trend as the proximate analysis. The microbial density of the samples showed that samples pretreated with 0.5% citric acid had the lowest count followed by samples pretreated with 0.5% sodium metabisulphite while the untreated samples had the highest microbial density. This implies that pretreatment with citric acid and sodium metabisulphite reduced the microbial density which may invariably extend the storage life of the edible oyster mushroom.

Malnutrition is the largest risk factor caused by inadequate nutrition that leads to childhood morbidity and mortality, as well as inadequate growth and development. Infants are at increased risk of malnutrition by six months, when breast milk alone is no longer sufficient to meet their nutritional requirements. However the factors associated with nutritional status of infants after 6 months of age have received little attention in pastoralist communities of Ethiopia. The aim of this study was to assess the complementary foods of infants and young children (6-23 months) in Gode town of Kebele 01. The prevalences of wasting, stunting and underweight among infants and young children were 6.1%, 56.1%, 10.0% reespectively. Undernutrition is a public health problem among infants and young children in Gode town of Kebele 01. Breastfeeding was slightly positive associated with lower chances of wasting at r=0.61, p= 0.01 and underweight at r=0.331, p=0.01. While diarrheal disease was associated with higher chances of wasting and underweight. Initiation of complementary food was slightly positive association with wasting at r=0.179, p=0.05.

Noodles are strips or strands cut from a sheet of dough made from flour, water and either common salt or a mixture of alkaline salt. Noodles consumption represents about 40% of the total wheat flour which are mainly consumed by school children. The use of composite flour has been encouraged since it reduces the importation of wheat. Utilization of locally available, inexpensive materials like cocoyam that can substitute a part of wheat flour without adversely affecting the acceptability of the product will be a product development. This study therefore studied the chemical composition and organoleptic properties of instant noodles from the blend of wheat and cocoyam starch. Cocoyam starch was substituted into wheat flour at 20, 40, 60 & 80%. Analysis revealed higher carbohydrate (63.50-70.05)%, moisture (4.54-5.07)% and vitamin A (10.01-30.47) mg/100g, B1 (11.43-32.15) mg/100g but lower protein (4.56-8.79)%, phosphorus (0.34-0.52)%, calcium (1.83-0.98)%, iron (0.15-0.32) % and ash (1.19-3.20)%. The composite noodles revealed higher carbohydrate and mineral but lower protein than the commercial noodles. The sensory analysis revealed that 20% cocoyam compared favourably with the commercial noodles in terms of all the sensory attributes evaluated. This shows the possibility of producing noodles from cocoyam tubers which serves as novel food. This will further help to promote and improve utilization of cocoyam tuber.

The seasonal nature of most fruits available in the market coupled with inadequate storage and processing facilities has limited their consumption by majority of the people in the country. Jams made from fruits are good bread spread rather than any other food products because they serve as adequate balance diet and it contains antioxidant such as vitamin C and A which play an important role in preventing cancer, cardiovascular problem and improvement of eyesight. Pawpaw and watermelon fruits have been reported to be nutritive and high in antioxidant properties that can scavenge free radicals, thereby improving the antioxidant status of the body. It is therefore deemed fit to produce jam from these perishable commodities in other to make them available all through the year and as well as adding to varieties of food products. The aqueous extracts of watermelon with pawpaw juice were processed into jam and the physicochemical properties of the jam samples were analysed. The resulting jam samples showed moisture content ranging between 30.60-35.30%, protein 0.40-0.80%, fat 0.20-0.40%, ash 1.20-1.70%, crude fibre 0.10-0.30%, carbohydrate 62.10-67.16%, β-carotene 610-1350µg/100g and ascorbic acid 9.60-15.40mg/100g. The jam samples were found to be very nutritive and high in antimicrobial and antioxidant properties that can scavenge free radicals, thereby can improve the antioxidant status of the body. Sensory evaluation tests showed that the samples were acceptable and compared favourably with the commercial imported brand while sample AA had the highest preference in all the sensory attributes evaluated by the panellists. Microbiological examination also showed that the jam samples had total plate count ranging from 4.10x101 to 2.00 x101 cfu/g, yeast and mould count ranged from 2.10x101 to 1.00 x101cfu/g with no observable coliform count.

The quality characteristics of selected black gram varieties viz., VBN 5, VBN 7, ADT 3, T9 and CO 6 and were evaluated for their suitability for the preparation of thick pancake. The foaming stability and foaming capacity were found to be maximum in VBN 5, CO 6 and T9. Maximum rise in volume was recorded in CO 6 (149 ml) followed by VBN 5 (148 ml) and T9 (147 ml) which is an indication good quality of thick pancake. Thick pancake prepared using 5 black gram varieties were analyzed for the physicochemical and microbial load. The texture profile viz., springiness, cohesiveness, chewiness and gumminess was evaluated for VBN 5, CO 6, T9 and VBN 7 respectively. The protein content was higher in thick pancake prepared from VBN 5 (25.47/100 g) compared to CO 6 (24.66 g/100g). Among the selected varieties, CO 6, T9 and VBN 5 had good batter content, texture, and microstructure and were found to be most suitable for thick pancake preparation.

A study on growth and carcass performance was conducted to evaluate the effect of Balanites aegyptiaca seed cake meal (BASCM) as a substitute for groundnut cake in the diet of growing rabbit. Five experimental diets were formulated representing the following treatments: T1, T2, T3, T4 and T5 respectively. T1 (0% BASCM) was served as the control diet, while T2, T3, T4 and T5 contained 25%, 50% 75% and 100% BASCM respectively. A total of 100 weaner rabbits of mixed breeds were purchased from the National Animal Production Research Institute (NAPRI), Zaria, Nigeria. The rabbits were fed the control diet during the one week of adjustment period. They were given vitalyte as anti-stress and were dewormed using ivermectin, at the end of one week of adjustment; the rabbits were housed in different hutches and fed their respective experimental diet for one month. Each treatment contained 20 rabbits and these treatments’ (T1-T5) each were replicated in four portions and each portion had five rabbits each. Results showed that all the parameters were significantly different (P<0.05) among the treatment groups. Balanites aegyptiaca seed cake meal can replace groundnut cake at 25% level inclusion without adverse effect on the rabbit physiology.

Emerging evidence indicates that micronutrient deficiency could play a significant role in the pathogenesis and progression of many chronic diseases including diabetes mellitus, hypertension, obesity, dyslipidemia, hyperuricemia, kidney disease, cancer, anemia and other cardio-metabolic and neurodegenerative diseases through the induction of Insulin resistance (IR). However, there are still gaps in our scientific knowledge regarding the links between micronutrient deficiencies, IR, and cardio metabolic disorders. This review provides current information on recent advances and a global perspective regarding the relationship between micronutrient deficiency, IR, and cardio metabolic disorders. Empirical evidence indicates that deficiencies in either micronutrients associated with insulin activity (such as Chromium, manganese, magnesium, and iron) or antioxidant enzyme cofactors (such as vitamin A, copper, zinc, and manganese) could impact several physiological processes leading to a cascade of metabolic and biochemical derangements such as B-cell apoptosis, loss of islet cell mass, defective tyrosine kinase activity, oxidative stress, pancreatic β-cell dysfunction, reduction in lean body mass, defective insulin signaling mechanism, elevated protein kinase C activity, and excess intracellular calcium. Collaboratively, these states of metabolic malfunctioning are associated with IR, which triggers the onset of many cardio metabolic diseases. Undoubtedly, the prevention of micronutrient deficiency may indeed ameliorate the incidence of IR and cardio-metabolic disorders in those at risk and in the general population.

Two experimental feeding trials were conducted concurrently to study the growth response of African catfish Clarias gariepinus fingerlings to graded levels (0, 5, 10, 15 or 20%) of clupeids in Danish fish meal (DFM) based diets. Chemical analysis of the DFM and clupeids fish meal (CFM) was carried out. Completely randomized design with triplicated groups of fingerlings were used for both trials in an indoor and out-door concrete tanks for six and twelve weeks respectively. The study aimed at achieving a cost effective fish meal from local aquatic resources (clupeids fish) highly prolific and abundant in Nigeria water bodies to replace foreign fish meal in West Africa Region. A project supported by West African Agricultural Productivity Project (WAAPP) in NIFFR, Nigeria. The results of proximate, amino acid profile, mineral and fatty acid composition analysis of CFM indicated values which are very close to those of the DFM. The proximate analysis revealed CFM to contain 70.6% crude protein while DFM contains 72%. There were no significant difference between the treatments with respect to final weight, feed consumed, feed conversion ratio, digestibility and survival (P>0.05) although there was significant difference in specific growth rate (P<0.05) with the highest value obtained in the diets with both fish meal at ratio 1:1. There were no significant difference in haematological parameters (P>0.05). However the lymphocytes were high in all the groups which might not be particularly due to the treatments. The high proliferation of the body defence cells by the fish could be a mechanism of survival in the aqua-medium which is likely to be high in microbial load due to waste materials. Feed Cost/Kg for DFM was N260.16 while for CFM was N227.16. The results of chemical analysis and feeding trials indicated positive replacement of the DFM with CFM in fish feeds without negative effect on growth performance

Roux-en-Y Gastric Bypass surgery is superior to medical treatment for short- to medium-term remission of Type 2 diabetes (T2DM) [1]. Recent research indicates that the improvements in insulin sensitivity following bariatric surgery are associated with elevated circulating bile acid concentration and remodeling of gut microbiota [2]. Gut microbiome can be considered as a target of dietary interventions or medicines to prevention/treatment of hyperglycemia in T2DM. Since, the glucose-lowering effects of metformin are mediated by changes in the composition and function of gut microbiota [3,4].

The consumption of dietary herbs and supplements may be associated with several physiological consequences including, but not limited to disturbances of acid-base homeostasis, minerals and electrolytes wasting, gastrointestinal disturbances as well as hemodynamic changes. Plants food based nutritional studies are important for assessing the effect of plants on human health and wellbeing. The aim of this study was to assess the changes in acid-base status and electrolyte homeostasis following the consumption of lemongrass tea. The acute and sub-chronic effects of infusions prepared from 2, 4, and 8g lemongrass leaf powder on serum and urinary pH, and electrolytes levels were assessed in 105 subjects using an interventional study design. The results post-treatment were compared with baseline values. Plasma pH decreased from baseline value of 7.37 ± 0.02 to 7.20 ± 0.03, and 7.30 ± 0.02 at days 10 and 30 respectively for participants treated with infusion prepared from 2g of lemongrass leaf powder. For those treated with infusion prepared from 4g of lemongrass leaf powder, plasma pH decreased from baseline value of 7.35 ± 0.02 to 7.22 ± 0.02 and 7.29 ± 0.02 at days 10 and 30 respectively. Treatment with infusion prepared from 8g of lemongrass leaf powder caused a decrease in plasma pH from baseline value of 7.38 ± 0.02 to 7.15 ± 0.02 and 7.18 ± 0.02 at days 10 and 30 respectively. Corresponding changes in urinary pH were also observed. Furthermore, at days 10 and 30, plasma protein concentrations increased significantly (p < 0.05) in subjects treated with infusion prepared from 8g lemongrass leaf extract. There were also significant increases (p < 0.05) in urinary volume, urination frequency, and urinary electrolytes levels within the same period. The consumption of lemongrass tea may be associated with changes in acid-base balance and electrolyte homeostasis due to its varied biological constituents and their activities

The study aimed to identify possible environmental risk factors for breast cancer among women in Gaza Strip and conducted in 2010. A case- control study design was used with face to face interviews by structured questionnaire with breast cancer patient women as well as healthy women. Statistical Package of Social Science (SPSS) was used to analyze the collected data. The study population was 288 women, 144 were women with breast cancer (cases) and 144 were healthy women (controls) with response rate 100% for cases as well as controls. The study was carried out in the two main hospitals in Gaza Strip (El-Shifa and European Gaza) and on cases who had a regular follow up in each hospital, while controls have been chosen from women who had no history of breast cancer by mammogram or by self-examination. In this study the main statistically significant risk factors were; marital status, educational status, physical trauma on breast, medication for infertility treatment, eating red meat 500g or more weekly, eating canned food, eating chicken skin, eating raw and cooked vegetables, using oils with saturated fats in cooking, living in or beside a farm, dealing with crops with naked hands, working in a farm during pesticides application or during 24 hours of pesticides application, cleaning pesticides’ equipment, living with people working in a farm or a agricultural field, and application of pesticides personally. In contrary, no statistically significant differences were found between cases and controls in relation to area of residency, exposure to X-ray in the past, having radiation therapy, getting contraceptive pills, using hair dyes, using anti-deodorant underarm, using facial cosmetics, using hair removal ointment, washing vegetables and fruits, buying and transporting pesticides, and wearing protective tools during pesticides mixing and application.

When a woman consults a doctor about Hormone Replacement Therapy (HRT), the first concern is that there is an increased risk of breast cancer with HRT. And this sole reason might be the reason for refusing the offer of HRT. However, this practice has minimal basis and evidence to support it. Although HRT is an umbrella term, women who have no uterus receive oestrogen-only HRT or Estrogen Replacement therapy (ERT). No valid study has linked ERT with an increased risk of breast cancer [1,2].
