Synthesis and Optical Properties of Highly Stabilized Peptide- Coated Silver Nanoparticles

The interaction between the silver nanoparticle and peptide surfaces has been of increased interest for the applications of bionanotechnology and tissue engineering. In order to completely understand such interactions, we have examined the optical properties of peptide-coated silver nanoparticles. However, the effect of peptide binding motif upon the silver nanoparticles surface characteristics and physicochemical properties of these nanoparticles remains incompletely understood. Here, we have fabricated sodium citrate stabilized silver nanoparticles and coated with peptide IVD (ID3). The optical properties of these peptide-capped nanomaterials were characterized by UV-visible, transmission electron microscopy (TEM), and z-potential measurement. The results indicate that the interface of silver nanoparticles (AgNP)-peptide is generated using ID3 peptide and suggested that the reactivity of peptide is governed by the conformation of the bound peptide on the silver nanoparticle surface. The interactions of peptide-nanoparticle would potentially be used to fabricate specific functionality into the various peptide-capped nanomaterials and antibacterial applications

ANTIOXIDANT AND HEPATOPROTECTIVE ACTIVITY OF ABELMOSCHUS MANIHOT L. MEDIK LEAF FRACTION AGAINST CCL4-INDUCED LIVER DAMAGE IN RATS

Objective: The objective of this research was to determine the antioxidant and hepatoprotective activity of Abelmoschus manihot L. Medik (AMLM) leaves in carbon tetrachloride-induced liver damage in rats (Rattus norvegicus). Methods: Samples of dried leaf were macerated using 96% ethanol solvent to obtain a viscous extract. Fractionation was then performed using ethyl acetate and n-butanol solvent. The antioxidant activity test of each fraction was done by 1,1-diphenyl-2-picrylhydrazyl assay. For the hepatoprotective activity test, the fractions were suspended in Tween 20 0.4% solution with concentrations of 10 mg/mL and 20 mg/mL. Rats were divided into 6 treatment groups consisting of five rats/group. Group I (positive control) was given an oral suspension of Curcuma® tablet, Group II (negative control) was given Tween 20 0.4% solution, and Groups III and IV (ethyl acetate fraction) and V and VI (n-butanol fraction) were given fraction suspension. On the 1st–7th days, all groups were given the solution treatment, and on the 8th day, all groups were injected with CCl4 intraperitoneally and the treatment was continued until the 11th day. On the 12th day, the blood of rats was taken and then measured the serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT). Results: The results of the antioxidant test showed that ethyl acetate and n-butanol fraction, respectively, had IC50 of 89.99 and 114.56 ppm.Measurement of SGOT showed the result for Groups I–VI, respectively, of 160±63.62, 260.53±18.98, 154.16±52.78, 177.43±13.70, 120.07±34.80, and 105.23±40.49 IU/L. Measurement of SGPT showed the result for Groups I–VI, respectively, of 101.87±29.24, 108.1±9.04, 57.73±49.05, 106.07±26.45, 66.9±20.05, and 146.63±84.89 UI/L. Conclusion: The results of this research indicated that the ethyl acetate and n-butanol fraction of AMLM leaves have the antioxidant andhepatoprotective activity

Analisis Kandungan Karbon Monoksida (CO) Pada Mesin Diesel Dan Bensin

This research studies to know monoxide carbon content at gasoline engine and diesel with revolution of the same engine. Assaying is done by using exhaust emission of gas test device to know monoxide carbon content at diesel engine Yanmar L-40 and gasoline engine endure XL. From result of assaying indicates that ever greater of revolution hence carbon content increasingly increases. At gasoline engine and addition diesel of fuel does not influence increase of percentage of monoxide carbon but at increase of revolution of this engine has been formed monoxide carbon. This thing because of existence of domination Fuel in combustion chamber so that partly fuel is not combustible causes the forming of monoxide carbon at exhaust gas. ever greater of efficiency thermal hence monoxide carbon grade increasingly increases. Thereby Monoxide carbon yielded by Diesel Engine exhaust gas Yanmar L 40 slimmer while at gasoline engine Enduro XL carbon monoxide yielded quite a lot

Intervention strategies for the reduction of sexual risk practices among adolescents in Ethiopia

BACKGROUND: Studies done in both developed and developing countries have reported the tendencies of adolescents to engage in risky behaviours. Such behaviours include indulging in early and unsafe sexual activities, having multiple sexual partners, alcohol and drug use and dropping out of school among others. PURPOSE: The main aim of the study was to develop intervention strategies for reducing sexual risk practices among adolescents in Ethiopia. METHODS: A mixed method approach using quantitative and qualitative approaches was employed in order to investigate the risks of sexual practices among urban and rural adolescents in the selected area. A cross-sectional survey was used to gather data quantitatively and focus group discussions were used for the qualitative part of data collection. A total of 449 students and 72 FGD participants were selected for quantitative and qualitative study respectively using systematic random sampling technique. Logistic regression was done to identify possible factors associated with knowledge on emergency contraceptive, condom utilisation, pre-marital sex practices and perception of risky sexual practices. RESULTS: One hundred and seventy (37.9%) respondents had experienced sexual intercourse at the time of the study. The higher proportion (42.6%) of those who had engaged in sexual relationships was from the rural school compared to 33.1% in the urban schools. The proportion of sexually active respondents was higher among males (44.8%) compared to (29%) females. Multiple partners were higher in rural adolescents (44.7%) compared to 31.8% among urban adolescents. Sexually Transmitted Diseases were reported by 28.6% of the sexually active adolescents and the prevalence was higher among males (73.5%) compared to 27% females. 87% of the sexually active adolescents rarely used a condom. CONCLUSION: The study identified a knowledge gap on ASRH which limited adolescents to access reproductive services. Social, cultural and economic factors contributed to adolescent engagement in risky sexual behaviours. Based on the major findings of this study, intervention strategies targeting behavioural, biomedical and structural interventions were proposed.Health StudiesD. Litt. et Phil. (Health Studies
