Utilization of Treated Seed Kernel Flours of Some Fruits in Biscuit Manufacture

During the processing of fruits, large quantities of wastes are generated, these by-products contain large amounts of oil, starch and protein that can be exploited due to their good nutritional, technological, and functional properties. However, due to the presence of several antinutritional factors, such as polyphenolic compounds, phytic acid, cyanogenic glycoside and oxalates, the use of fruit wastes in human food is limited. The present investigation was aimed to study the effect of soaking and heating on antinutritional factors. It also examines the effect of substituting defatted apricot, peach, and mango seed kernel flours for wheat flour in various ratios (5, 10, and 15%) on the chemical composition, physical features, and sensory properties evaluation of biscuits. The results revealed a significant effect of soaking and heating on the antinutrients, detoxification led to a significant (p≤0.05) decrease in antinutritional factors with ratios 43.63-52.73% total phenols, 78.17-86.16% tannins, 45.92-54.34% phytic acid and 40.42-44.70% oxalates, along with the complete removal (100%) of hydrocyanic acid (HCN). Wheat biscuit contained 3.20% moisture, 6.31% protein, 15.46% fat, 0.64% crude fiber, 1.25% ash and 76.33% carbohydrate. Highly acceptable biscuits could be obtained by incorporating 5% of defatted apricot, peach and mango kernel flours in the wheat biscuits formulation. As a by-product, apricot, peach and mango kernels offer an exciting potential as a food ingredient permitting to enrich biscuits and enlarge the food base for consumers.

Renal failure and neonatal death following snakebite during pregnancy: a case report

A thirty-five-year-old Sudanese woman (gravida 4, para 3), at 34 weeks gestational age, presented with snakebite in her right leg. Examination of the cardiovascular, respiratory, gastrointestinal, and central nervous systems revealed no abnormalities. Her blood urea was 58 mg/dl; creatinine, 2.6 mg/dl; whole blood clotting time, 5:35 minutes. The patient was diagnosed as having acute renal failure and was then managed conservatively. She received polyvalent antivenom serum intravenously. On the next day, she delivered prematurely and the baby passed away due to respiratory distress. There was no postpartum bleeding and the patient's clotting time was 5:30 minutes. She was discharged from the hospital after 7 days when her clinical, biochemical and hematological parameters returned to normal values without dialysis.(AU)

Efficacy of flumethrin and coumaphos against the camel tick Hyalomma dromedarial L. [Acari: ixodidae]

The efficacy of Flumethrin pour on and Coumaphos 50% WP was tested against different stages of Hyalomma dromedarii. With contact method, LC[50] values for larvae and adults were 0.04, 0.03 ug/cm[2] and 0.05, 1.06 ug/cm[2] respectively. The LC[50] for coumaphos against the larvae, adults and eggs using dipping method were 44, 63, and 62 ppm respectively. Flumethrin caused significant reduction in oviposition and hatchability in female ticks that survived sublethal concentrations, while sublethal doses of coumaphos had no effect on the reproductive potential of the tick. The results showed that flumethrin was 8 times more toxic than coumaphos

role of amalgam mix and corrosion upon the edge strength of some dental amalgams

The purpose of the present work was to study the effect of time ofcondensation and corrosion upon the edge strength of some amalgam alloys. Theangle of amalgam margins for all the samples has measured 70C and it wassubjected to a load of 500 gm. Amalgam condensation was made at 1, 2, 4 and 5min. after the end of trituration. Corrosion of amalgam samples was done bystoring the samples in 0.01 M lactic acid buffered with NaCl 0.02% adjusted topH 4. For the corroded samples, it was found that conventional amalgam showeda severe deterioration of the edge strength. While, for the non-gamma II, therewas a decrease in edge strength, but not statistically significant. For allthe investigated amalgam alloys, it was found that a triturated mix when kept5 min in air before condensation showed a marked reduction in the edgestrength

In-vitro study: the effect of plasticity, time of condensation upon surface roughness of some amalgam alloys

The present work was performed to evaluate the role of some variables that mayaffect the surface roughness of dental amalgam. Three different types ofcommercial amalgams were used in this study. The combination of variablesincluded in this work were plasticity of the triturated mix, and time elapsingfrom the end of trituration up to start of condensation. The results showedthat the surface roughness of the investigated amalgams was affected markedlyby the studied variables

Curing contraction of some elastomeric impression materials

The curing contraction in% [%] of seven elastomeric impressionmaterials, available on the Egyptian market, was measured by means of amercury bath technique. Measurements were done at different time intervalsafter mixing for 15 min, 60 min and 24 hr. Four of the elastomeric impressionmaterials tested in the present study [Coltex, Impregum, Brovil and Reproisl]showed a curing contraction of 0.08% after 24 hr. Although the presenttechnique is a simple test compared to ADA No. 19 for measuring thedimensional changes of elastic impression materials, yet the effectivecontraction determined as the accuracy of stone dies produced by dentalimpressions perhaps is more realistic than the free contraction of theimpression by either mercury bath technique or by the ADA No. 19

In-vitro study on dimensional changes of composite cores

Dimensional changes for the composite cores, after using two types ofcomposite resin, caused by water sorption were measured. Three differenttechniques for the retention of composite cores were followed. Thesetechniques were slot technique, T.M.S. pins applied vertically on the dentinefloor and T.M.S. pins as before but were then bended. Measurements ofdimensional changes were done using a stereomicroscope for 1 day, 3 days and 7days after water immersion. The results of the present study showed that forboth types of composite resin investigated, bending the pin after beingapplied vertically on dentine floor showed the least values of dimensionalchanges. For all the variables included in this study, it was found thatafter three days storage in water, there were no dimensional changes. It isadvocated from the findings of this study to delay crown preparation in caseof composite cores a few days later to avoid discrepancy due to hygroscopicexpansion caused by water sorption

role of some cleansing agents upon removal of dentinal-smeared layer: a scanning electron microscope study

The purpose of this paper was to study the role of some cleansing agents uponthe removal of smeared layer formed on the cut dentin surface. The differentcleansers used in the present study were EDTA, phosphoric acid, citric acid,ascorbic acid, sodium chloride and deionized water. The results of thepresent study showed that the application of EDTA, phosphoric acid andascorbic acid for one minute has removed the smeared layer formed onto the cutdentin surface. On the other hand, washing the cut dentin surface withdeionized water or NaCl for one minute did not remove the smeared layer. Theapplication time, upon the removal of the dentinal smeared layer, of thevarious inorganic acids used in the present work was also studied

Bonding strength of ASPA cement filling to hard tooth structure

The purpose of the present study was to determine the role of application time for ferric chloride solution upon bonding strength between ASPA cement filing and dentin, after which dentin was formally washed for one minute by means of phosphoric acid solution 5% [W/W]. Also, it aimed to study the effect of alternative application of phosphoric acid and ferric chloride upon bonding strength between ASPA cement and enamel. For bonding strength between ASPA cement and dentin, it was found that the optimum values of bonding strength were obtained when ferric chloride was applied for one minute. In case of enamel, it was found that ferric chloride seemed to have no effect upon the bonding strength between ASPA cement filling and enamel
