Perbandingan antigen larut (SA) Brugia malayi dan Brugia pahangi di dalam pengembangan sistem ELISA untuk diagnosis penyakit Filaria

Brugia malayi and Brugia pahangi adult worm soluble antigens were used in digoxigenin-sandwich ELISA to detect filarial specific anti-IgG4 and antiIgG2 antibodies in different groups of filarial patients, soil-transmitted helminth infected patients and in normal individuals. Both kinds of antigens showed positive IgG4 responses with all sera of microfilaraemic patients. However, ELISA using B. pahangi antigen also showed positive ELISA readings with some sera of patients with soil-transmitted helminth infections and some sera of normal individuals. On the other hand no such cross-reactivities were demonstrated when B. malayi was used as the antigen. In the analysis of anti-filarial IgG2 antibody responses, all chronic elephantiasis sera gave positive readings in ELlS As that employed B. malayi as the antigen; and no cross-reactivity with other helminthic infections were observed. In comparison, only some sera of chronic elephantiasis patients were positive for antifilaral IgG2 antibodies when B. pahangi was used as the antigen. Furthermore, with the use of B. pahangi antigen coated plates, some sera from soil-transmitted helminth infected patients and from normal individuals also showed positive titres of antifilarial IgG2 antibodies. This study demonstrated that B. pahangi soluble adult worm antigen is not a suitable substitute for B. malayi soluble adult worm antigen in the diagnosis of brugian filariasis by ELISA

Analisis kecekapan teknikal firma melayu dalam sektor pembuatan Malaysia

Purpose - this article aims to analyse and identify determinants of technical efficiency of Malay owned firm in the manufacturing sector. Design/Methodology/Approach - The analysis is based on 246 Malay owned firms surveyed in 2001/2002. Two levels of estimation are conducted, firstly, estimation of technical efficiency and secondly, estimating the tobit model to identify determinants of technical efficiency. Finding - The result from the first estimation shows that, in general, technical efficiency for the Malay owner firms is still at the medium level. The most efficiency sub-industry is fabricated metal, machines, electrical, and transportation equipment, whereas the least efficient is non-metalic, glass, and ceramic products. Furthermore, from the second estimation, the study are firm size and entrepreneur's level of education. Originality/Value - Studies on firms' technical efficiency particularly addressing the Malays are very limited. Most studies in this area focus on the industry in general.The finding from the study are crucial for entrepreneurs and the government. Identifying the determinants of technical efficiency may guide the Malay entrepreneurs to restructure their planning. The government, on the other hand, may learn from the findings in formulating its strategies to help the Malay entrepreneurs. Paper type - Research Pape

Material and Methods Fifty persons were included, twelve patients received Ginkgo biloba capsule (75mg) twice daily compared with twelve patients received placebo capsule for 8 weeks at Al-Kadhimyia Teaching Hospital. Twenty six healthy volunteers considered as control. Patient's history was taken and measurement of neutrophils percentage, serum Glutathione (Elleman methods), Malonialdehyde (Stocks and Dormandy methods), Interlukine -6 (Elisa) and Vitiligo area scoring index (VASI) at baseline, 4 and 8 weeks interval, as a parameters to indicate the impact of Ginkgo biloba on the disease.  Results and discussion showed significant decrease in serum interlukin-6 (S. IL-6) after 4 weeks between Ginkgo biloba group and placebo group. No significant difference was found in Neutrophils percent between Ginkgo biloba group and placebo group after 4 and 8 weeks. There was a significant increase in serum glutathione (S. GSH) after 4 and 8 weeks in Ginkgo biloba. Serum malondialdehyde (S. MDA) showed no significant difference between Ginkgo biloba group and placebo group after 4 and 8 weeks and no changes in VASI were found after 8 weeks between Ginkgo biloba and placebo group. Conclusion Ginkgo biloba may has good activity in vitiligo treatment. Keywords: Ginkgo biloba, vitiligo, antioxidant

Simulation and modeling of the behavior in the four-stroke spark ignition engine by using CFD simulation

Computational fluid dynamics (CFD) is a branch of fluid mechanics that use numerical analysis and data structures to analyze and solves problems that involve fluid flows. CFD have been applied to a wide range of research and engineering problems in many fields of study and industries, including engine and combustion analysis. The objective of this review paper is to analyze the behavior in the four-stroke Spark Ignition (SI) engine by using CFD simulation. To get the require result a few methods have been used to analyze the behavior in the engine such as using CAD geometric model where the solid works software have been prepared. Then, in the CAD geometric model also have ANSYS software to perform analysis in engine module. To predict the behavior of the engine during its working two type of analysis can be performed namely port flow simulation and combustion simulation. So, in first part of this report, the CFD analysis is carried out to analyze the performance parameter, including intake stroke, compression stroke, power stroke and exhaust stroke with hexane fuel combustion. For the results, some details of the engine model and some predicted results including temperature, flow time and pressure profiles. With the existence of CFD simulation it can help many fields of study and industries by predict and analyze the possibility that can be happened in the future.

Socio-demographic determinants of Toxoplasma gondii seroprevalence in migrant workers of Peninsular Malaysia

Background The number of migrants working in Malaysia has increased sharply since the 1970’s and there is concern that infectious diseases endemic in other (e.g. neighbouring) countries may be inadvertently imported. Compulsory medical screening prior to entering the workforce does not include parasitic infections such as toxoplasmosis. Therefore, this study aimed to evaluate the seroprevalence of T. gondii infection among migrant workers in Peninsular Malaysia by means of serosurveys conducted on a voluntary basis among low-skilled and semi-skilled workers from five working sectors, namely, manufacturing, food service, agriculture and plantation, construction and domestic work. Methods A total of 484 migrant workers originating from rural locations in neighbouring countries, namely, Indonesia (n = 247, 51.0%), Nepal (n = 99, 20.5%), Bangladesh (n = 72, 14.9%), India (n = 52, 10.7%) and Myanmar (n = 14, 2.9%) were included in this study. Results The overall seroprevalence of T. gondii was 57.4% (n = 278; 95% CI: 52.7–61.8%) with 52.9% (n = 256; 95% CI: 48.4–57.2%) seropositive for anti-Toxoplasma IgG only, 0.8% (n = 4; 95% CI: 0.2–1.7%) seropositive for anti-Toxoplasma IgM only and 3.7% (n = 18; 95% CI: 2.1–5.4%) seropositive with both IgG and IgM antibodies. All positive samples with both IgG and IgM antibodies showed high avidity (> 40%), suggesting latent infection. Age (being older than 45 years), Nepalese nationality, manufacturing occupation, and being a newcomer in Malaysia (excepting domestic work) were positively and statistically significantly associated with seroprevalence (P < 0.05). Conclusions The results of this study suggest that better promotion of knowledge about parasite transmission is required for both migrant workers and permanent residents in Malaysia. Efforts should be made to encourage improved personal hygiene before consumption of food and fluids, thorough cooking of meat and better disposal of feline excreta from domestic pets
