THE EFFECTS OF DIETARY FOOD FORTIFIED WITH VITAMIN B4 ON LIPID PROFILES IN SERUM AND LIVER TISSUE
Yohanes Buang
Makara Seri Kesehatan , 2010,
Abstract: The effects of dietary food fortified with vitamin B4 on lipid profiles in serum and liver tissue were studied. Rats were paired-fed a 0.25% vitamin B4 diet or a diet without vitamin B4 for 10 days. Serum lipid levels were measured using enzyme assay kits. Lipids of liver tissues were extracted and the lipid contents were determined. A piece of liver was prepared to determine the activities of fatty acid synthase (FAS) and fatty acid β-oxidation. The results showed that animals fed a food fortified with vitamin B4 had higher level of serum TG, PL, total cholesterol, and high density lipoprotein. Their increases were approximately by 74%, 20%, 27%, and 27%, respectively. The significant changes in liver lipid were only found in PL component. This treatment promoted FAS activity, but impaired the fatty acid β-oxidation. In conclusion: Dietary food fortified with vitamin B4 induces hypertriglyceridemia and liver PL level.

Makara Seri Sains , 2011,
Abstract: The effects of dietary food fortified with orotic acid (1.0%) on liver function were studied in rats. The rats fed withorotic acid promoted liver triglyceride content markedly, that was 5-fold higher than that of the control. The livermalondialdehyde (MDA) content increased by 10%, but the gluthation peroxidase (GSH-Px) activity decreased by 50%.The serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities increased by 25% and 30%,respectively. Therefore, the decreased GSH-Px activity was associated with the promotions of AST, ALT, and the liverMDA levels. In conclusion: dietary orotic acid promotes lipid peroxidation but reduces the rate of the antioxidantenzyme. Therefore, dietary food fortified with orotic acid attenuates the liver function.

Bangladesh Journal of Pharmacology , 2010,
Abstract: The effects of dietary shochu kasu (5%) on orotic acid-induced fatty liver were studied in rats. Liver triglyceride content of orotic acid-fed rats increased by 5-fold in comparison to basal group. Shochu kasu reduced triglyceride content by two-third. The activities of fatty acid synthase and phosphatidate phosphohydrolase significantly decreased that was approximately by 35% and 20%, respectively. The serum lipid levels however were nearly unchanged. The alleviation of fatty liver in rats with shochu kasu, therefore, was associated with the inhibition of fatty acid synthase and phosphatidate phosphohydrolase activities.

Research Journal of Applied Sciences , 2012, DOI: 10.3923/rjasci.2011.282.289
Abstract: The purpose of this study was to explore the entrepreneurship career paths of Malaysian graduate entrepreneurs who graduated from local and overseas higher learning institutions between the years of 1988 to 2003. The paths explored in this study include career-changing phases starting from early career intentions up to business start-ups. This study also find out which entrepreneurship career paths mostly taken and least taken by the graduate entrepreneurs such as incremental path intuitive path, methodical path and accidental path based on their level of education, their field of studies (program majors) and whether local or overseas higher learning institutions attended. A set of questionnaire was constructed and a total of both 399 local and overseas graduate entrepreneurs were randomly selected from the total population of the graduate entrepreneurs. Descriptive statistics such as the frequency and percentage were used to present the graduate entrepreneurs profile, their career-intentions changing phases and entrepreneurial career paths taken. The findings show that accidental path was the most taken entrepreneurial career path followed by methodical intuitive and incremental paths regardless of their level of education, field of studies and local or overseas higher learning institutions. The implications of the findings suggest that universities in the country should evaluate the effectiveness of their entrepreneurship programs s curriculum in terms of increasing the number of graduates choosing the intuitive and incremental paths to entrepreneurs.
Memahami permasalahan pelancongan di Kundasang, Sabah: kekuatan dan kelemahan pendekatan positivisme
Ramzah Dambul,Amriah Buang
Geografia : Malaysian Journal of Society and Space , 2008,
Abstract: Kertas ini secara asasnya cuba mengupas permasalahan pelancongan di Kundasang (Sabah) berdasarkan pendekatan epistemologi positivisme. Tujuannya ialah untuk (i) memaparkan beberapa aspek lahiriah (empirikal) kepincangan industri pelancongan di kawasan berkenaan, (ii) menjelaskan kepincangan ini dari perspektif postivisme sendiri, dan (iii) menunjukkan bagaimana penjelasan yang lebih bererti dapat dan harus didatangkan dari pendekatan-pendekatan epistemologi selain positivisme. Adalah didapati bahawa kekuatan perspektif positivisme ialah dalam mengenalpasti tiga faktor utama yang mempengaruhi kegagalan industri pelancongan sebagai katalis pembangunan Kundasang, iaitu pertumbuhan pusat urban yang lembab, kebocoran pendapatan, dan tahap mandiri’ penduduk setempat yang lemah. Kelemahan perspektif positivisme ialah kegagalannya mengungkap dan menjawab dua persoalan kritikal yang mendasari permasalahan pelancongan di Kundasang, iaitu: (i) Mengapakah aliran modal asing yang masuk ke kawasan Kundasang gagal memberi kesan pengganda dan limpahan ekonomi di peringkat lokal ?; dan (ii) mengapakah kedatangan para pekerja migran yang agak besar jumlahnya tidak memberi sumbangan kepada pertumbuhan fungsi runcit dan perkhidmatan urbanisasi di Kundasang? Kertas ini menyimpulkan bahawa jawapan kepada dua persoalan dasar itu memerlukan aplikasi pendekatan bukan positivism.

Abstract: Rahawarin Y (2011) Forest land use by the community in Sorong Natural Tourism Park at Sorong City, West Papua Province. Biodiversitas 12: 222-227. The aim of the research was to: (i) identify the type and extent of forest land use alteration at Sorong Natural Tourism Park (or SNTP), (ii) investigate society activities that cause forest land use alteration, and (iii) make the zoning level of environmental damage (iv) investigate the causative factors of forest land use alteration at SNTP. The method used was survey with field observation and semi-structural interview techniques. The primary data of biophysical aspects consist of type and extents of land usage by society; while data of socio-cultural aspects consist of level of community dependency upon land and the existing of local institution and management of SNTP. Secondary data that had been collected consist of study results documentation and report of SNTP management aspects. Data were analyzed by using (i) qualitative descriptive analysis of society socio-cultural and management aspects, (ii) spatial analysis of biophysical aspects, and (iii) environmental analysis of biophysical, socio-cultural and management aspects. Evaluation of environmental analysis was used to arrange directive and environmental management strategy at SNTP. Result of research indicated that since its establishment in 1981 to 2009, SNTP forest land utilizing for settlements, forest product extraction and shifting cultivation activity by society had been cause of land use alteration occurred which was incompatible with area function about 11,53%. Changing in the land use caused by society activities in land utilizes such settlements, forest product extraction and shifting cultivation. Level of environmental degradation in the catchments area of damage SNTP level indicates that 8.01% of total of land area was in slightly damaged, 2.36% was moderately damaged and 1.16% is in heavily damaged. Inadequate support on socio-cultural aspects of society at SNTP and the lack of founding and supervising upon SNTP management was pointed as causative factors on environmental damage. Based on level of environmental damage, community based forest management system will be able to be implemented as environmental management strategy at SNTP.
