Cathodic stripping voltammetry of peptide complexes
Small peptides containing the histidine residue are
considered as models of the metal binding site of bioactive
peptides and proteins. The present study has been
concerned with the cathodic stripping voltammetry of the
copper complexes of imidazole (the parent molecule), and
several histidine containing peptides; glycylglycyl-L-histidine
(GGH), glycyl-L-histidylglycine (GHG), L-histidylglycine
(HG), glycyl-L-histidine (GH), Carnosine
(Car) and thyrotropine releasing factor(TRF). Accumulation
and reduction mechanisms were further studied by cyclic
voltammetry, and indirect cathodic stripping voltammetric
method of determining these peptides has been developed. [Continues.
Optimization of Antioxidants with Different Fermentation TIME in the Salvage Industry Infertile Eggs
The eggs infertile is one alternative food to meet the nutritional needs and other benefts of eggs. The study aims to determine the effect of different fermentation time of the optimization efforts antioxidants in infertile eggs hatching the remaining results. The study design used a completely randomized design (CRD) with three treatments and fve replications. Study treatment was 0, 2 and 4 days. Materials used are infertile eggs hatching period of 18 days as many as 45 items.

Karakteristik Whey Limbah Dangke Dan Potensinya Sebagai Produk Minuman Dengan Menggunakan Lactobacillus Acidophilus FNCC 0051
Dangke whey has not been widely utilized. Dangke whey handling is required for the prevention of environmental pollution, especially in Enrekang. Evaluating the characteristics of dangke whey is the initial step of dangke whey handling. Complete data about the dangke whey would be scientific information for researchers or the public to further the utilization. Nutritional value of dangke whey allows the use of Lactobacillus acidophilus FNCC 0051 to be processed into beverage products. This research objectives were to investigate the characteristics of whey from dangke waste, which were obtained from milk protein separation by using lyophilization of papaya latex, and it also to evaluate the potential of dangke whey as beverage product by using Lactobacillus acidophilus FNCC 0051. A commercial fermented beverages product is used as a comparison, based on the activity of growth/bacteria numbers, lactic acid and pH. Milk was added with enzyme solution (lyophilized latex) on the level of 0.4 to 1% (v/v). The best level was used for the production of the fermented whey beverage products. Whey was mixed with tapioca level of 0, 0.35, 0.7, 1.05, and 1.4%, and was heated by stirring for 5 minutes at temperature of 70oC. The whey was pasteurized at the temperature of 80oC for 30 minutes. The whey was cooled, and inoculated with L.acidophilus at the level of 1, 3, 5, and 7%, and incubated at 37°C for 8, 12, 16, 18, and 24 hours, respectively. The characteristics of whey dangke were as follows: the solid total was 6.95 ± 0.23%, lactic acid was 0.1 ± 0.003%, fat was 0.2 ± 0.05%, protein was 0.63 ± 0.009%, lactose was 5.08 ± 0.009%, pH was 6.31 ± 0.01, and viscocity was 0.19 ± 0.004 poise. Dangke whey is potential as a beverage products with the addition of Lactobacillus acidophilus with quality similar to the commercial fermented beverage after incubated for 16 hours, with the addition of inoculum level of 5% and tapioca level of 0.35% based on the activity of growth, lactic acid and pH

The prevalence of macrovascular complications among diabetic patients in the United Arab Emirates
<p>Abstract</p> <p>Background</p> <p>Diabetes Mellitus (DM) is a major public health problem in the UAE with a prevalence rate reaching 24% in national citizens and 17.4% in expatriates. The aim of this study was to determine the prevalence and risk factors of macrovascular complications among diabetic patients in the Al-Ain district of the United Arab Emirates (UAE).</p> <p>Methods</p> <p>The study was part of a general cross-sectional survey carried out to assess the prevalence of diabetes (DM) complications among known diabetic patients in Al-Ain District, UAE. Patients were randomly selected during 2003/2004. Patients completed an interviewer-administered questionnaire carried out by treating doctors and underwent a complete medical assessment including measurement of height, weight, blood pressure and examination for evidence of macrovascular complications. A standard ECG was recorded and blood samples were taken to document fasting blood sugar, glycosylated haemoglobin (HbA<sub>1C</sub>) and lipid profile.</p> <p>Results</p> <p>A sample of 513 diabetic patients was selected with a mean age of 53 years (SD ± 13.01). Overall, 29.5% of DM patients had evidence of macrovascular complications: 11.6% (95% CI: 8.8–14.4) of patients had peripheral vascular disease (PVD), 14.4% (95% CI: 11.3–17.5) had a history of coronary artery disease (CAD) and 3.5% (95% CI: 1.9–5.1%) had cerebrovascular disease (CVD). Of the total population surveyed 35% (95%CI: 30.8–39) had hypertension. The analysis showed that macrovascular complications in diabetic patients were more common among males, increased with age, were more common among hypertensive patients and its prevalence increased steadily with duration of DM.</p> <p>Conclusion</p> <p>Our data revealed a significant association between hypertension and presence of macrovascular disease among diabetic patients. However, the risk of CAD in the UAE was relatively low compared to that seen in patients in other geographical settings. In addition, a lack of correlation between macrovascular disease and glycemic control among patients with DM was observed.</p

Nitric Oxide and Abscisic Acid Mediate Heat Stress Tolerance through Regulation of Osmolytes and Antioxidants to Protect Photosynthesis and Growth in Wheat Plants
Nitric oxide (NO) and abscisic acid (ABA) play a significant role to combat abiotic stress. Application of 100 µM sodium nitroprusside (SNP, NO donor) or ABA alleviated heat stress effects on photosynthesis and growth of wheat (Triticum aestivum L.) plants exposed to 40 °C for 6 h every day for 15 days. We have shown that ABA and NO synergistically interact to reduce the heat stress effects on photosynthesis and growth via reducing the content of H2O2 and thiobarbituric acid reactive substances (TBARS), as well as maximizing osmolytes production and the activity and expression of antioxidant enzymes. The inhibition of NO and ABA using c-PTIO (2-4 carboxy-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) and fluridone (Flu), respectively, reduced the osmolyte and antioxidant metabolism and heat stress tolerance. The inhibition of NO significantly reduced the ABA-induced osmolytes and antioxidant metabolism, exhibiting that the function of ABA in the alleviation of heat stress was NO dependent and can be enhanced with NO supplementation.Thus, regulating the activity and expression of antioxidant enzymes together with osmolytes production could act as a possible strategy for heat tolerance
