Abstract: A cross-sectional study among 15,639 Malaysian adult males aged 18 years and above was conducted using proportional to size stratified sampling method. The socio-demographic variables examined were level of education, occupation, marital status, residential area, age group and monthly household income.The prevalence of smoking among adult males in Malaysia was 46.5% (95% CI: 45.5–47.4%), which was 3% lower than a decade ago. Mean age of smoking initiation was 18.3 years, and mean number of cigarettes smoked daily was 11.3. Prevalence of smoking was highest among the Malays (55.9%) and those aged 21–30 years (59.3%). Smoking was significantly associated with level of education (no education OR 2.09 95% CI (1.67–2.60), primary school OR 1.95, 95% CI (1.65–2.30), secondary school OR 1.88, 95% CI (1.63–2.11), with tertiary education as the reference group). Marital status (divorce OR 1.67, 95% CI (1.22–2.28), with married as the reference group), ethnicity (Malay, OR 2.29, 95% CI ( 1.98–2.66; Chinese OR 1.23 95% CI (1.05–1.91), Other Bumis OR 1.75, 95% CI (1.46–2.10, others OR 1.48 95% CI (1.15–1.91), with Indian as the reference group), age group (18–20 years OR 2.36, 95% CI (1.90–2.94); 20–29 years OR 3.31 , 95% CI 2.82–3.89; 31–40 years OR 2.85 , 95% CI ( 2.47–3.28); 41–50 years OR 1.93, 95% CI (1.69–2.20) ; 51–60 years OR 1.32, 95% CI (1.15–1.51), with 60 year-old and above as the reference group) and residential area (rural OR 1.12 , 95% CI ( 1.03–1.22)) urban as reference.The prevalence of smoking among Malaysian males remained high in spite of several population interventions over the past decade. Tobacco will likely remain a primary cause of premature mortality and morbidity in Malaysia. Continuous and more comprehensive anti-smoking policy measures are needed in order to further prevent the increasing prevalence of smoking among Malaysian men, particularly those who are younger, of Malay ethnicity, less educated, reside in rural residential area and with lower

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.412A1001

This paper describes the application of principal component analysis (PCA) and artificial neural network (ANN) to predict the air pollutant index (API) within the seven selected Malaysian air monitoring stations in the southern region of Peninsular Malaysia based on seven years database (2005-2011). Feed-forward ANN was used as a prediction method. The feed-forward ANN analysis demonstrated that the rotated principal component scores (RPCs) were the best input parameters to predict API. From the 4 RPCs, only 10 (CO, O3, PM10, NO2, CH4, NmHC, THC, wind direction, humidity and ambient temp) out of 12 prediction variables were the most significant parameters to predict API. The results proved that the ANN method can be applied successfully as tools for decision making and problem solving for better atmospheric management.

Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.35A2003

Background: The purpose of this study was to compare the effectiveness of Letrozole versus Clomiphene citrate for ovulation induction in polycystic ovarian syndrome (PCOS) with infertility. Methods: This was a prospective randomized trial involving 150 women with PCOS attending the Infertility Clinic at three hospitals in Malaysia. During the initial visit, anthropometric measurements and baseline investigations were performed. Patients were randomized to 5.0 mg Letrozole daily (75 patients) or 100 mg Clomiphene citrate daily (75 patients) from the fifth until the ninth day of menstruation. Serial transvaginal scans were performed to see the dominant follicles, endometrial thickness and number of follicles. Transvaginal scans were performed serially to look for evidence of ovulation. Results: The subjects were homogenously distributed. The difference between Letrozole and Clomiphene citrate for ovulation rate was 59 (78.7%) versus 40 (53.3%). Patients taking Letrozole exhibited a mean endometrial thickness (ET) at mid cycle of menses (Day 11-D14) of9.2 mm(SD ± 2.3) versus8.4 mm(SD ± 2.2) for patients taking Clomiphene citrate, and these differences were statistically significant (p < 0.001). In terms of pregnancy rate, Letrozole facilitated pregnancy induction in 19 patients (25.3%) versus 12 patients (16.0%) for Clomiphene citrate; however, this was not statistically significant (p = 0.22). More dominant follicles exhibiting a monofollicular morphology were observed in patients treated with Letrozole compared to patients treated with Clomiphene citrate, with a monofollicular dominant follicle observed in 33 (46.5%) versus 20 (26.7%) patients, respectively. Conclusion: Letrozole provided a more efficient stimulation compared to Clomiphene citrate in terms of ovulation induction, thickening of the endometrial lining and achievement of a successful pregnancy.

The diagnosis of breast cancer can cause a significant anxiety in someone’s life. The care of the breast cancer patient requires in many centres. The care of breast cancer patient is undertaken as a joint venture between the surgeon, medical oncologist, radiotherapist, pathologist and allied health professionals such as the clinical nurse specialist as well as counsellors. This is a case of a 39-years-old Malay woman presented to HUSM with a history of ulcerating breast lump with bloody pus discharge on the right breast. An initial mammogram study showed lesion suspicious of malignancy, and histopathological examination was consistent with invasive ductal carcinoma. She received neoadjuvant chemotherapy before proceeding to right modified radical mastectomy with axillary clearance and immediate chest wall reconstruction. Detailed discussion on the diagnosis, treatment, surgical intervention and progress of the patient with reference to available literature reviews are presented.

Abstract: Cross-disciplinary research is a research activity that involves researchers of multiple disciplines in studying new knowledge. Cross-disciplinary research extends beyond simple collaboration to integrate data, methodologies, perspectives and concepts from various fields to understand the basics or find the solution for real world problems. The approach of cross-disciplinary research taken at the Faculty of Engineering and Built Environment (FKAB), in transforming the researcher, is still deem to be at its minimum because there has yet to be a study on unravelling the difficulties and challenges of reinforcing cross-disciplinary research. Furthermore, the absence of a guideline for conducting such research prohibits the researcher to pursue his research into different discipline. The purpose of this paper is to examine the challenge and difficulty factors that contribute to the less than effective cross-disciplinary researches at the FKAB in particular, and in UKM in general. In addition, through the conducted data analysis, a preliminary guideline can be formed, which can then be used as a guide and resource to develop awareness and capability in implementing cross-disciplinary research. The study was conducted using qualitative and quantitative methods. The qualitative method taken was distributing a questionnaire to academicians at the FKAB. Data obtained are then analysed using WinSteps 3.68.2, which is software utilised in Rasch analysis. Overall, results show that the main factor contributing to difficulties in implementing cross-disciplinary research is the need for solid financial funding.

Abstract: Research on entrepreneurship intention has and continues to be of interest to researchers due to its importance to the development for many countries. The literature on entrepreneurship intention has examined various issues with many focusing on the factors that influence entrepreneurship intention. However, most of these studies were conducted in a non-Malaysian setting. This study examines entrepreneurship intention among Malaysian Business Students. Using a questionnaire survey on undergraduate business students in a Malaysian public university, this study examines whether business students have an intention to pursue entrepreneurship. It also examines whether personality traits and environmental factors influence the students to become entrepreneurs. The results indicate that more than half of the respondents have an intention to become entrepreneurs and their decisions are attributed by the influence from their family members, academics and attending courses on entrepreneurship. The results also show that out of the two factors: personality traits and environmental, personality traits play an important role in influencing the students’ decision to become entrepreneurs. The findings implicate that academics need to play a significant role in encouraging more students to become entrepreneurs by providing more awareness on the benefits of becoming entrepreneurs and in turn, contributing to the growth of the country’s economies and global competitiveness. Keywords: Entrepreneurship intention; business students; perceived desirability; personality traits; environmental factors; Malaysia Résumé: La recherche sur l'esprit d'entreprise a et continue d'avoir des intérêts pour les chercheurs en raison de son importance pour le développement de nombreux pays. Des études sur l'esprit d'entreprise ont examiné de diverses questions en mettant l'accent sur les facteurs qui influencent l'esprit d'entreprise. Cependant, la plupart de ces études ont été menées dans un cadre non malaisien. Cette étude examine l'esprit d'entreprise chez les étudiants en commerce malaisiens.En utilisant l'enquête par questionnaire sur les étudiants de premier cycle dans une université publique de Malaisie, cette étude examine si les étudiants en commerce ont l'intention de poursuivre l'esprit d'entreprise. Il examine également si les traits de personnalité et les facteurs environnementaux influencent les étudiants qui veulent devenir entrepreneurs. Les résultats indiquent que plus de la moitié des répondants ont l'intention de devenir entrepreneurs et leurs décisions sont attribuées par

Open Journal of Applied Biosensor (OJAB) , 2014, DOI: 10.4236/ojab.2014.32002
Abstract: Herein we report an electrochemical DNA biosensor for the rapid detection of sequence (5’ AAT GGA TTT ATC TGC TCT TCG 3’) specific for the breast cancer 1 (BRCA1) gene. The proposed electrochemical genosensor is based on short oligonucleotide DNA probe immobilized onto zinc oxide nanowires (ZnONWs) chemically synthesized onto gold electrode via hydrothermal technique. The morphology studies of the ZnONWs, performed by field emission scanning electron microscopy (FESEM), showed that the ZnO nanowires are uniform, highly dense and oriented perpendicularly to the substrate. Recognition event between the DNA probe and the target was investigated by differential pulse voltammetry (DPV) in 0.1 M acetate buffer solution (ABS), pH 7.00; as a result of the hybridization, an oxidation signal was observed at +0.8 V. The influences of pH, target concentration, and non-complimentary DNA on biosensor performance were examined. The proposed DNA biosensor has the ability to detect the target sequence in the range of concentration between 10.0 and 100.0 μM with a detection limit of 3.32 μM. The experimental results demonstrated that the prepared ZnONWs/Au electrodes are suitable platform for the immobilization of DNA.

Abstract: The helminth community structures of two urban rat populations in Kuala Lumpur, Malaysia were investigated. The rats were from two contrasting sites in the city caught over a period of 21 months in 2000-2002.Eleven species of helminth parasites comprising seven nematodes (Heterakis spumosum, Mastophorus muris, Nippostrongylus brasiliensis, Syphacia muris, Pterygodermatites tani/whartoni, Gongylonema neoplasticum, Angiostrongylus malaysiensis), three cestodes (Hymenolepis (Rodentolepis) nana, H. diminuta and Taenia taeniaeformis) and one acanthocephalan (Moniliformis moniliformis) were recovered from 346 Rattus rattus and 104 R. norvegicus from two urban sites, Bangsar and Chow Kit, during 2000-2002. Rattus rattus harboured over 60% of all helminths compared with R. norvegicus, although both host species played a dominant role in the different sites with, for example R. norvegicus at Bangsar and R. rattus at Chow Kit accounting for most of the nematodes. Overall 80% of rats carried at least one species of helminth, with the highest prevalences being shown by H. diminuta (35%), H. spumosum (29.8%) and H. nana (28.4%). Nevertheless, there were marked differences in prevalence rates between sites and hosts. The influence of extrinsic (year, season and site) and intrinsic (species, sex and age) factors affecting infracommunity structure (abundance and prevalence of infection) and measures of component community structure were analyzed.Since at least two species of rat borne helminths in Kuala Lumpur have the potential to infect humans, and these showed high prevalences in the rats, the assessment and regular monitoring of infections carried by wild rodents have important roles to play in public health.The prevalence of parasitic infections among commensal animals in many tropical countries is high and poses threats to human health since people living in close proximity to rodent populations that act as reservoirs of infection, or to secondary hosts, can be exposed to inf

Abstract: Bioethanol production using yeast has become a popular topic due to worrying depleting worldwide fuel reserve. The aim of the study was to investigate the capability of Malaysia yeast strains isolated from starter culture used in traditional fermented food and alcoholic beverages in producing Bioethanol using alginate beads entrapment method. The starter yeast consists of groups of microbes, thus the yeasts were grown in Sabouraud agar to obtain single colony called ST1 (tuak) and ST3 (tapai). The growth in Yeast Potatoes Dextrose (YPD) resulted in specific growth of ST1 at = 0.396 h-1 and ST3 at = 0.38 h-1, with maximum ethanol production of 7.36 g L-1 observed using ST1 strain. The two strains were then immobilized using calcium alginate entrapment method producing average alginate beads size of 0.51 cm and were grown in different substrates; YPD medium and Local Brown Sugar (LBS) for 8 h in flask. The maximum ethanol concentration measured after 7 h were at 6.63 and 6.59 g L-1 in YPD media and 1.54 and 1.39 g L-1 in LBS media for ST1 and ST3, respectively. The use of LBS as carbon source showed higher yield of product (Yp/s), 0.59 g g-1 compared to YPD, 0.25 g g-1 in ST1 and (Yp/s), 0.54 g g-1 compared to YPD, 0.24 g g-1 in ST3 . This study indicated the possibility of using local strains (ST1 and ST3) to produce bioethanol via immobilization technique with local materials as substrate.
