Genetic Diversity of Streptococcus uberis Strains Isolated from Clinical and Subclinical Cases of Bovine Intramammary Infections in Malaysia
Md. Firoz Mian,Abdul Rahim Mutalib,Mohd Azmi Mohd Lila,Abdul Aziz Saharee
Pakistan Journal of Biological Sciences , 2002,
Abstract: Random amplified polymorphic DNA (RAPD) analysis was employed on twenty-four Streptococcus uberis isolates from cases of clinical and sub-clinical mastitis from five smallholder dairy herds in Malaysia. Three ten-mer primers namely OPA-01, OPA-05 and OPA-07 were selected out of a 20 primers set. A high degree of genetic polymorphism was revealed among the isolates of S. uberis by RAPD-PCR. Fourteen distinct RAPD fingerprint patterns were generated with primer OPA-05, while primers OPA-01 and OPA-07 produced 12 and 11 RAPD patterns respectively. The discriminatory power of this technique could be further improved by the parallel use of several primers. Most of the isolates were genetically different strains, however, identical patterns were noted among different cows within the same farm or from different cows from different farming regions. These findings indicate that RAPD analysis is a rapid and reproducible method for molecular sub-typing of bovine S. uberis isolates and therefore, represents a powerful tool for epidemiological studies.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.3474.3480
Abstract: Seroepidemiological survey of Caseous Lymphadenitis (CLA), a bacterial infection in sheep and goats was conducted in East Coast Economic Regions (ECER) in peninsular Malaysia. A total of 422 animals (n = 422) from 15 small ruminant farms (sheep and goats) in the four states were screened during the period from January to April 2011. The management practices that could be associated with CLA occurrence was also analyzed. The objective of this survey was to determine the overall status of CLA infections in small ruminants. AGPT was conducted on serum samples collected from animals. About 47 samples out of 422 yielded a positive reaction for AGPT test. The frequency of CLA infections was estimated at 11.1%. Management practices were analyzed through questionnaire. All farmers (15/15) had semi-extensive rearing system; 27.6% (13/47) of farmers had periodical veterinary services; 10.6% (5/47) took note of animals with clinical signs of CLA; 14.8% (7/47) were aware of the zoonotic potential of this disease. Lack of sanitary measures and epidemiological studies led the dissemination of this disease in Malaysia. Moreover, the economic importance of this disease seems to be overlooked by both individual and state level allowing existence of endemic nature of the disease in this country. Therefore, further epidemiological studies using reliable diagnostic tools and application of appropriate management practices need to be implemented for aiding control and eradication programs for this disease.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4660.4667
Abstract: Corynebacterium pseudotuberculosis is the etiological agent of caseous lymphadenitis, a chronic infectious disease of sheep and goats. Despite the growing interest of this organism, little is known about the causality and effect of this organism on haematological and biochemical values. The purpose of this research, therefore was to determine haematological and serum biochemical features in mice inoculated with whole bacterium and exotoxin (PLD) extracted from C. pseudotuberculosis. The study was performed on apparently healthy mice of 2-3 weeks old (n = 64). The mice were divided equally into 3 groups; namely whole bacterium, exotoxin (PLD) and control group. Mice of whole bacterium group were exposed intraperitoneally to 1 mL of the inoculums containing 109 Colony-Forming Unit (CFU)/mL of live C. pseudotuberculosis. Exotoxin group were exposed intraperitoneally with a single dose of exotoxin (PLD) extracted from C. pseudotuberculosis. Mice served as a control group were challenged intraperitoneally to 1 mL of Phosphate-Buffered Saline (PBS), pH 7. Following post-infection, the mice were subjected for blood sample collection using cardiac puncture method for haematological and biochemical analysis. The results of this study revealed that there were significant decrease (p<0.05) in Hb, thrombocytes count and significant increase in WBC, neutrophils, monocytes counts in the infected group. Biochemically, there were highly significant increase (p<0.05) in the mean levels of CK, AST, ALP and ALT. The mean level of albumin in exotoxin group was significantly lower (p<0.05) compared to C. pseudotuberculosis and control groups while globulin level was significantly higher in C. pseuodotuberculosis group after 48 h. In serum electrolytes, mean level of potassium and phosphate were significantly (p<0.05) higher in infected groups compared to control group while there was no significant (p<0.05) difference in the levels of sodium, calcium and chloride. In conclusions, the present study of experimental nature showed that C. pseudotuberculosis and its exotoxin (PLD) cause disturbances in blood factors and electrolytes and pointed out that t hese haematological and biochemical alterations should be taken into account in the context of diagnosis and treatment of valuable infected hosts in order to prevent further consequences.

Comparative Evaluation of the Anti-ulcer Activity of Curcumin and Omeprazole during the Acute Phase of Gastric Ulcer—Efficacy of Curcumin in Gastric Ulcer Prevention against Omeprazole  [PDF]
Karolin Kamel Abdul-Aziz
Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.26088
Abstract: We have confirmed in our laboratory the antiulcer activity of curcumin during the acute chronic phase of gastric ulcer disease at doses of 20, 40 and 80 mg/kg (dissolved in saline solution). In the previous study, the potent effective dose of curcumin was 80 mg/kg that appears a propitious protective effect against gastric ulcer development. Therefore, the comparison between such recommended dose of curcumin and one of the proton pump inhibitors (PPIs) staff is worth-while. Since, the pharmacological control of gastric acid secretion is the main desired goal for gastro-cytoprotection, particularly, the H+/K+-ATPase (acid proton pump) inhibitors. Nevertheless, several studies have indicated that long-term inhibition of gastric acid secretion results in mucosal hyperplasia and carcinoid tumor development, due to increase circulating gastrin levels. Ulcer and the preventive indexes were scored, mucin, juice volume, total acidity, luminal haemoglobin, total antioxidant and total peroxide were evaluated. The pro-inflammatory cytokine IL-6 and the major angiogenic growth factor VEGF levels were measured. Conclusion, curcumin and omeprazole are potentially preventing gastric lesions development in the gastric wall during the acute phase of gastric ulcer diseases, but curcumin was more potent in its effect. Curcumin promotes gastric ulcer prevention/healing by induction of angiogenesis in the granular tissue of ulcers. That may be via upregulation of VEGF expression as reflected from VEGF level in serum and gastric juice, however, omeprazole might be has no role in this story.

Abdul Aziz
Entropy , 2006, DOI: 10.3390/e8020050
Abstract: The present paper is concerned with an analytical study of entropy generation in viscous, incompressible Couette flow between a stationary plate and a moving plate. The flow induced by the moving plate is assisted by a constant pressure gradient along the flow direction. Four different combinations of thermal boundary conditions are investigated: (a) plates at different temperatures, (b) stationary plate at a fixed temperature and moving plate subjected to a constant heat flux, (c) stationary plate at a fixed temperature and convection at the moving plate, and (d) convection at both plates. Besides the velocity and temperature profiles, dimensionless results are presented for the entropy generated due to heat transfer, the entropy generated due to viscous dissipation, and the total entropy generation. These results illustrate the effect of pressure gradient, temperature asymmetry, heat flux, convection Biot numbers, and ambient temperatures. For certain combinations of thermal variables, the total entropy generated is minimized.

Negin Vaghefi, Chamhuri Siwar, Sarah Aziz Abdul Ghani Aziz
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.51006
Abstract: Developing countries like most of Islamic countries need an economy that promotes growth and development, conserves natural capital, creates jobs, improves human well-being, and alleviates poverty and inequality. Such an economy is called green economy. Main problems that create a hard situation to implement green economy in most of Islamic countries are weak management, increasing poverty, many local and border conflicts, high economic dependency on natural re- sources, and increasing food insecurity. Governments as policy makers could introduce policies, regulations and incentives to promote green economy. This paper therefore attempts to discuss on how green economy can improve the livelihood security and poverty eradication in Islamic countries. It also seeks to understand which key intervention is needed to achieve a green economy in Muslim countries.

American Journal of Operations Research (AJOR) , 2013, DOI: 10.4236/ajor.2013.32023
Abstract:

An accurate prediction of crude palm oil (CPO) prices is important especially when investors deal with ever-increasing risks and uncertainties in the future. Therefore, the applicability of the forecasting approaches in predicting the CPO prices is becoming the matter into concerns. In this study, two artificial intelligence approaches, has been used namely artificial neural network (ANN) and adaptive neuro fuzzy inference system (ANFIS). We employed in-sample forecasting on daily free-on-board CPO prices in Malaysia and the series data stretching from a period of January first, 2004 to the end of December 2011. The predictability power of the artificial intelligence approaches was also made in regard with the statistical forecasting approach such as the autoregressive fractionally integrated moving average (ARFIMA) model. The general findings demonstrated that the ANN model is superior compared to the ANFIS and ARFIMA models in predicting the CPO prices.

Cross-Cultural Communication , 2011, DOI: 10.3968/1016
Abstract: It may be a truism that culture and language are intricately interwoven and that language is the basis of culture, but this tradition has been mostly absent in the concern for second culture acquisition. Theoretically, there is a solid recognition in pertinent literature that teaching English cannot be isolated from teaching its culture. This article, basically a discussion paper, introduced cultural awareness as a significant step towards activating a sound theory of English teaching and learning pedagogy. Towards this purpose, the article has outlined the concepts of culture in English language teaching (ELT), acculturation, cultural competence and cultural awareness as basic steps for inducing effective communication. The differences between Arabic and English cultures, and the need for cultural awareness were also discussed. The article has also discussed how to foster students’ cross-cultural awareness in EFL teaching, and the implications of this in EFL teacher education programmes. Key words: Cross-cultural awareness; Language; Culture; EFL; ELT; Acculturation; EFL teacher educationResumé: Cela peut être un truisme que la culture et la langue sont complexent entrelacés et cette langue est la base de culture, mais cette tradition a été surtout absente dans la préoccupation pour la deuxième acquisition de culture. Théoriquement, il y a une reconnaissance solide dans la littérature pertinente apprenant l'anglais ne peut pas être isolé d'apprendre sa culture. Cet article, essentiellement un journal de discussion, la conscience culturelle présentée comme une étape significative vers l’activation d'une théorie du son d'enseignement d’anglais et l’étude de pédagogie. Vers ce but, l'article a souligne les concepts de culture dans l'enseignement de l'anglais (ELT), l'acculturation, la compétence culturelle et la conscience culturelle comme des étapes de base pour inciter la communication efficace.Les différences entre des cultures arabes et anglaises et le besoin de la conscience culturelle ont été aussi discutées. L'article a aussi discuté comment favoriser la conscience multiculturelle des étudiants dans l'enseignement d'EFL et les implications dans l'enseignement des professeur EFL.Mots-clés: Conscience multiculturelle; Langue; Culture; EFL; ELT; Acculturation; EFL enseignement(éducation) de professeur
