Microalgal like Chlorella vulgaris, being a unicellular green algae, is been widely studied for nitrogen and phosphorus removal and as potential feedstock for biodiesel production. This not only saves water from eutrophication but also becomes a good source of biodiesel. Hence, if two approaches are combined we can overcome the major challenge of both eutrophication and energy crisis. In the present study we have examined the effect of decreasing Nitrogen and phosphorus concentration in medium on growth, biomass and lipid content of C. vulgaris. Significant decrease in growth and biomass was observed with the decrease of nitrogen and phosphorus concentration in the medium from (1.5g/l to 0.0g/l) and (0.04g/l to 0.0g/l) respectively. Whereas the lipid accumulation showed reverse trend of increase when the concentration of both phosphorus and nitrogen where decreased in medium. At the same time, the effect of variation in pH and saline ranges on growth, biomass and lipid content of C.vulgaris were also evaluated. The growth, biomass and lipid content showed a significant difference due to...

Background: Sepsis is a significant public health concern and is the main cause of death in surgical intensive care units (ICUs). Patients with sepsis have features consistent with immunosuppression. Taurine is rapidly emerging as one of the more interesting amines which has been reported to have immune-modulatory effect through its action on cytokines. Purpose: To determine the effect of using Immune-enhancing enteral nutritional feed containing taurine compared to Standard enteral nutritional feed on clinical outcomes of ICU septic population. Methods: This was a prospective, randomized, controlled study. A total of 45 patients were randomly divided into 3 groups: Group 1 (n=15) received Standard Enteral Nutrition feed for two weeks, Group 2(n=15) received Immune-Enhancing Enteral Nutrition feed containing 10 mg/kg/day of Taurine for two weeks and Group 3(n=15) received Immune-Enhancing Enteral Nutrition feed containing 30 mg/kg/day of Taurine for two weeks. Parameters measured were serum levels of Interleukin-6, Interleukin-10, C-reactive protein and Total leukocyte count. Results: The current study showed that Taurine had immune-modulatory effect by significantly decreasing the level...

Rivaroxaban is a direct inhibitor for Factor Xa that used orally for prevention and treatment of thromboembolic disorders through inhibition of thrombin synthesis. In this study we hypothesis that rivaroxaban pretreatment might play a role in reducing the complications of myocardial ischemic reperfusion injury (IRI) in a rat model of obesity. R- hirudin (a commercially available anticoagulant drug used previously in attenuating the harmful effects of myocardial IRI) was used as a positive control in this study. To achieve this hypothesis, male Wistar albino rats were randomly assigned into 4 groups (n = 6 per group): control subjected to IRI, obese subjected to IRI, obese rats pretreated with r- hirudin (1.8 mg/kg body weight) then subjected to IRI, obese pretreated with Rivaroxaban (3 mg/kg body weight/day) then subjected to IRI. Obesity was induced by feeding rats high fat diet. Myocardial ischemia was induced by left anterior descending artery ligation (LAD). The obese rats subjected to IRI showed significant increases in the inflammatory markers (myocardial angiotensin II, tumor necrosis factor...

Malathion is a widely used organophosphorous pesticide that a large number of populations are undesirably exposing themselves to severe health risk due to taking up the contaminated foods, water and vegetables containing malathion. The present study was carried out through histopathologic test to evaluate the extent of damage caused by malathion in the liver and kidney tissues of mice. Twenty five adult female albino mice were used and dispense mainly into two groups as control group and treatment group. The mice of control group were feed with poultry food without any ingredient of malathion. Each of the treatment groups (group1, group 2, group 3 and group 4, containing five animals in each group) were supplied everyday with the same type of food containing the following amounts of malathion as 65mg, 13mg, 2.6mg, and 0.52mg per 50gm (10gm food/mouse) of food, respectively. After fifteen days the animals of both groups were sacrificed and the organs of sacrificed animal were subjected to histopathological examination and then visualized under light microscope. Results...

Compounds with a 2(H)-1, 4-benzoxazin-3(4H)-one skeleton have attached the attention of phytochemistry researchers since 2, 4-dihydroxy-(2H)-1,4-benzoxazin-3(4H) and 2,4-dihydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one were isolated from plants belonging to the Poaceae family. These compounds exihibit interesting properties11 such as phytotoxic, antimicrobial12, antifeedent, antifungal and insecticidal properties. The reaction of CSI with 2-Chlorobenzyl alcohol result in N-chlorosulphonyl derivatives, which show antibacterial potency. Futher, N-chlorosulphonyl derivatives can be easily cyclofunctionalized. This cyclofunctionalization has been exploited in the synthesis of the title compounds (3). Thus, the title compound being oxygen analogues of 1, 3-thiazine derivatives together with N-sulphonamide moiety could be expected to exhibit enhanced...
