E.B. Akhmedova,Z.A. Toguzova,M.N. Mamedov
Rational Pharmacotherapy in Cardiology , 2013,
Abstract: Diabetes mellitus (DM) is one of the health and social problems of modern health care. The main causes of death in patients with DM are macrovascular complications. Intensive hypoglycemic therapy is recommended to prevent complications; however it can increase the risk of severe hypoglycemia with subsequent growth rate of mortality. Glucose blood levels should be monitored to reduce the risk of cardiovascular disease and death, as well as control of normoglycemia and risk factors are needed. DM pathogenesis and prevalence are considered, and effects of glucose blood level on its outcomes are analyzed.
REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation
Biodiversitas , 2005,
Abstract: An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another. There are many studies have been done in cryopreservation of fish spermatozoa. However, there are few review have been done. This review reveals some aspects of cryopreservation especially the role of extender and cryoprotectant in fish sperm cryopreservation. Fish produce high viscosity of sperm and in some cases only small volume is produced. Before cryopreserved in liquid nitrogen, sperm have to dilute with extenders and for long-term cryopreservation, cryoprotectants are needed to protect the sperm cell from cold and hot shock treatments and prevent cell dehydration during pre-freezing, freezing and post thawed. The suitability of extenders and cryoprotectants differs from one fish to another. Over the last decade, studies on the cryopreservation of mammalian sperm, animal husbandry sperm and human sperm have progressed significantly but studies on fish sperm is still confined to some aquatic.

Inas Z.A. Abdallah
Egyptian Journal of Hospital Medicine , 2008,
Abstract: Background: Opuntia dillenii Haw fruit is used in folk medicine as an antidiabetic agent. The aim of this study was to evaluate the possible curative role of O. dillenii fruit juice using the streptozotocin (STZ)-induced diabetic rats. The nutritive value of the edible portion of the fruit was also assessed. Results: The results showed that O. dillenii fruit is a rich source of fiber, carbohydrates, vitamins B1, B2 and C, in addition to the minerals, Fe, Zn, Cu, Cr, Mn, Ca, and Mg. Biological results showed that intraperitoneal injection with STZ caused highly significant reduction in body weight gain% , highly significant elevation in blood glucose concentration accompanied by significant reduction in liver glycogen cotent as compared with control group. Diabetic rats also revealed significant elevation in lipid peroxide (MDA) level, highly significant elevation in total cholesterol (TC), triacylglycerols (TAG), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) concurrent with highly significant reduction in high-density lipoprotein cholesterol (HDL-C) as compared with control group. Oral administration of O. dillenii juice had no effect on normal rats. Meanwhile, oral administration of O. dillenii juice to diabetic rats induced siginficant improvement in body weight gain % and lipid profile, it reduced significantly blood glucose and MDA levels as compared with non treated diabetic group. Histopathological investigation of the pancreatic tissue of STZ-diabetic rats represented the presence of necrosis, edema and congested blood vessels in the islets of Langerhans cells. O. dillenii fruit juice treatment overcome the previous changes, the majority of the cells tend to be normal.The improvement in the cells of Langerhans islets may explain the antidiabetic effect of the fruit juice under study. It also may improve the insulin receptors of -cells. Conclusion: It could be concluded that O. dillenii fruit juice had a potent hypoglycemic activity, this effect may be attributed to its antioxidant activity and its high content of chromium which was proved in this study. Therefore, it could be recommended that O. dillenii should be ingested as fresh fruit to diabetic and hypercholesterolemic patients beside the usual therapy

Asian Journal of Scientific Research , 2008,
Abstract: This study was conducted to evaluate physicochemical and microbiological quality of raw, pasteurized and UHT milks in Shahrekord (Iran) in the spring 2005. All types of milk samples were collected from different part of the city were selected and in three consequent periods. The physicochemical parameters including fat, protein, temperature, Titrable Acidity (TA), Solid Not Fat (SNF) and Specific Gravity (SG) were determined. Additionally, the microbiological evaluations were based on the total bacterial count, total coliform count and Escherichia coli (E. coli). The results (mean values of 81 measurements) for raw milk samples showed fat content 2.6, protein 3.5, T 18 °C, TA 0.17, SNF 7.71 and SG 1.030 and total bacterial count 13x106 cfu mL-1, total coliform count 1300 cfu mL-1 and E. coli positive. Those values for the pasteurized milks were the fat content 2, protein 3.5, T 15 °C, TA 0.16, SNF 7.5 and SG 1.033 and total bacterial count 71x104 cfu mL-1, total coliform count 800 cfu mL-1 and E. coli positive. Furthermore, the values of UHT milks were the fat content 2.8, protein 3.1, T 19 °C, TA 0.15, SNF 8.3, SG 1.029, total bacterial count 71 cfu mL-1, total coliform count 9 cfu mL-1 and E. coli negative. Statistical analysis of data revealed that there is significant difference between results of different shops at the level of p<0.01 which implies the contamination of raw and pasteurized milk is above standards.

Abstract: As the influential factors affecting intention to become an entrepreneur, entrepreneurial attitude orientation and self-efficacy of students have been one of the main focuses of entrepreneurship research. However, there is not enough information on secondary school students’ attitude toward and efficacy of entrepreneurship particularly, in Malaysia. Through a descriptive approach, this study aimed to determine entrepreneurial attitude and entrepreneurial self-efficacy in order to evaluate the entrepreneurship inclination and potential among Malaysian secondary school students. A sample of 2,574 students was randomly selected from three states around Malaysia as the participants of this study. A set of questionnaire was developed based on previous researches to measure students’ entrepreneurial attitude and self-efficacy. The findings indicate that Malay students have a moderately high attitude toward entrepreneurship. More specifically, the students scored high in self-esteem cognition and achievement cognition but low in self-esteem behavior and self-esteem affect. Moreover, the students perceived themselves as moderately capable of establishing new ventures. The implication of the findings and areas for future researches are discussed.
