Abstract: Study of kinds and tannin content of diets consumed by anoa is limited. This information is very important and necessary for anoa domestication. The aims of this research were to obtain information on kinds and tannin content of anoa diets. The research was conducted in forest of Pangi Binangga nature reserve and Lore Lindu National Park, province of Central Sulawesi in March to November 2009. Digestive content analyses method was used to study the kinds of diets consumed by anoa. Chromatography was used for tannin analysis. Results of the digestive content analysis found ten kinds of anoa diets, i.e. Ficus miquelly, Caryota mitis, Ficus ampelas, Syzigium sp., Cordia mixab, Paspalum conjugatum, Smilax leocophylla, Saccarum spontaneum, Isachne globosa and Imperata cylindrica. The proportion of the diets were 60%, 45%, 35%, 17%, 12%, 10%, 8%, 8%, 5%, and 4%, respectively. Three of six diets namely Ficus miquelly, Saccarum spontaneum and Isachne globosa contained low tannin. The tannin content of three diets was 0.34%, 0.61%, and 0.99%, respectively. It is concluded that anoa in forest prefer diets that contain low tannin, such as Ficus fruits, shoots of shrubs.

Abstract: dification of palm kernel oil esters nanoemulsions with hydrocolloid gum for enhanced topical delivery of ibuprofen Original Research (1662) Total Article Views Authors: Salim N, Basri M, Rahman MBA, Abdullah DK, Basri H Published Date September 2012 Volume 2012:7 Pages 4739 - 4747 DOI: http://dx.doi.org/10.2147/IJN.S34700 Received: 06 June 2012 Accepted: 25 July 2012 Published: 07 September 2012 Norazlinaliza Salim,1 Mahiran Basri,1,2 Mohd BA Rahman,1 Dzulkefly K Abdullah,1 Hamidon Basri3 1Department of Chemistry, Faculty of Science, 2Laboratory of Biomolecular Medicine, Institute of Bioscience, 3Department of Medicine, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, Selangor, Malaysia Introduction: During recent years, there has been growing interest in the use of nanoemulsion as a drug-carrier system for topical delivery. A nanoemulsion is a transparent mixture of oil, surfactant and water with a very low viscosity, usually the product of its high water content. The present study investigated the modification of nanoemulsions with different hydrocolloid gums, to enhanced drug delivery of ibuprofen. The in vitro characterization of the initial and modified nanoemulsions was also studied. Methods: A palm kernel oil esters nanoemulsion was modified with different hydrocolloid gums for the topical delivery of ibuprofen. Three different hydrocolloids (gellan gum, xanthan gum, and carrageenan) were selected for use. Ternary phase diagrams were constructed using palm kernel oil esters as the oil, Tween 80 as the surfactant, and water. Nanoemulsions were prepared by phase inversion composition, and were gradually mixed with the freshly prepared hydrocolloids. The initial nanoemulsion and modified nanoemulsions were characterized. The abilities of the nanoemulsions to deliver ibuprofen were assessed in vitro, using a Franz diffusion cell fitted with rat skin. Results: No significant changes were observed in droplet size (~16–20 nm) but a significant difference in polydispersity indexes were observed before and after the modification of nanoemulsions using gellan gum, carrageenan, and xanthan gum. The zeta potentials of the initial nanoemulsions (–11.0 mV) increased to –19.6 mV, –13.9 mV, and –41.9 mV, respectively. The abilities of both the initial nanoemulsion (T802) and the modified nanoemulsion to deliver ibuprofen through the skin were evaluated in vitro, using Franz diffusion cells fitted with rat skin. The in vitro permeation data showed that the modified nanoemulsion (Kp value of 55.4 × 10-3 cm h-1) increased the permeability of ibuprofen 4.40 times over T802 (Kp value of 12.6 × 10-3 cm h-1) (P < 0.05). Conclusion: The modified nanoemulsion may be a promising vehicle to enhance the permeation of ibuprofen for topical delivery.

ShahNor BASRI, M. M. FAKIR, F. MUSTAPHA, D. L. A. MAJID, A. A. JAAFAR
Engineering (ENG) , 2009, DOI: 10.4236/eng.2009.13018
Abstract: Finite element method (FEM) and differential quadrature method (DQM) are among important numerical techniques used in engineering analyses. Usually elements are sub-divided uniformly in FEM (conventional FEM, CFEM) to obtain temperature distribution behavior in a fin or plate. Hence, extra computational complexity is needed to obtain a fair solution with required accuracy. In this paper, non-uniform sub-elements are considered for FEM (efficient FEM, EFEM) solution to reduce the computational complex-ity. Then this EFEM is applied for the solution of one-dimensional heat transfer problem in a rectangular thin fin. The obtained results are compared with CFEM and efficient DQM (EDQM), with non-uniform mesh generation). It is found that the EFEM exhibit more accurate results than CFEM and EDQM showing its potentiality.

Malaysian Family Physician , 2012,
Abstract: Objective: To determine the prevalence of eye diseases and visual impairment among new patients at the eye clinic ofHospital Sultan Haji Ahmad Shah, Temerloh, Pahang.Method: In this cross-sectional prospective study, 1081 new patients were examined over a period of six months. Age,gender, ethnicity, visual acuity and diagnosis were noted from the medical records.Results: Out of 1081 examined, 607 (56.1%) were males, 783 (72.4%) were Malays. The mean age of patients was45.2 years (ranging from one month to 91 years). Cataract (248, 22.9%) was the most common eye disease, followed byretinal diseases (124, 11.5%) and ocular trauma (106, 9.8%). Majority of the patients (48) suffering from ocular traumahad foreign body cornea. In 85 premature infants screened for retinopathy, 19 showed different stages of retinopathy ofprematurity. Visual impairment was noted in 89 (8.2%) patients, severe visual impairment in 12 (1.1%) and blindness in 35(3.2%); vision could not be determined in 85 premature infants (7.9%). Cataract was singled out as the cause of severevisual impairment in 11 out of 12 patients.Conclusion: Health education at primary health centres and availability of eye specialists in all the district hospitals willfacilitate the rehabilitation of visually impaired and blind persons by providing early treatment for eye problems (specificallyprescription for spectacles, medical treatment and cataract surgery with intraocular lens implantation).
Rotation Periods, Variability Properties and Ages for Kepler Exoplanet Candidate Host Stars

Physics , 2013, DOI: 10.1093/mnras/stt1700
Abstract: We report rotation periods, variability characteristics, gyrochronological ages for ~950 of the Kepler Object of Interest host stars. We find a wide dispersion in the amplitude of the photometric variability as a function of rotation, likely indicating differences in the spot distribution among stars. We use these rotation periods in combination with published spectroscopic measurements of vsini and stellar parameters to derive the stellar inclination in the line-of-sight, and find a number of systems with possible spin-orbit misalignment. We additionally find several systems with close-in planet candidates whose stellar rotation periods are equal to or twice the planetary orbital period, indicative of possible tidal interactions between these planets and their parent stars. If these systems survive validation to become confirmed planets, they will provide important clues to the evolutionary history of these systems.

International Journal of Nanomedicine , 2012,
Abstract: CH Loo,1,2 M Basri,2 R Ismail,1 HLN Lau,1 BA Tejo,2 MS Kanthimathi,3 HA Hassan,1 YM Choo11Malaysian Palm Oil Board, Bandar Baru Bangi, 2Department of Chemistry, Universiti Putra Malaysia, Serdang, 3Department of Molecular Medicine, University of Malaya, Kuala Lumpur, MalaysiaPurpose: To study the effects of varying lipid concentrations, lipid and oil ratio, and the addition of propylene glycol and lecithin on the long-term physical stability of nanostructured lipid nanocarriers (NLC), skin hydration, and transepidermal water loss.Methods: The various NLC formulations (A1–A5) were prepared and their particle size, zeta potential, viscosity, and stability were analyzed. The formulations were applied on the forearms of the 20 female volunteers (one forearm of each volunteer was left untreated as a control). The subjects stayed for 30 minutes in a conditioned room with their forearms uncovered to let the skin adapt to the temperature (22°C ± 2°C) and humidity (50% ± 2%) of the room. Skin hydration and skin occlusion were recorded at day one (before treatment) and day seven (after treatment). Three measurements for skin hydration and skin occlusion were performed in each testing area.Results: NLC formulations with the highest lipid concentration, highest solid lipid concentration, and additional propylene glycol (formulations A1, A2, and A5) showed higher physical stability than other formulations. The addition of propylene glycol into an NLC system helped to reduce the particle size of the NLC and enhanced its long-term physical stability. All the NLC formulations were found to significantly increase skin hydration compared to the untreated controls within 7 days. All NLC formulations exhibited occlusive properties as they reduced the transepidermal water loss within 7 days. This effect was more pronounced with the addition of propylene glycol or lecithin into an NLC formulation, whereby at least 60% reduction in transepidermal water loss was observed.Conclusion: NLCs with high lipid content, solid lipid content, phospholipid, and lecithin are a highly effective cosmetic delivery system for cosmetic topical applications that are designed to boost skin hydration.Keywords: nanostructured lipid carriers, transepidermal water loss, skin hydration, particle size

Abstract: Flood forecasting models are a necessity, as they help in planning for flood events, and thus help prevent loss of lives and minimize damage. At present, artificial neural networks (ANN) have been successfully applied in river flow and water level forecasting studies. ANN requires historical data to develop a forecasting model. However, long-term historical water level data, such as hourly data, poses two crucial problems in data training. First is that the high volume of data slows the computation process. Second is that data training reaches its optimal performance within a few cycles of data training, due to there being a high volume of normal water level data in the data training, while the forecasting performance for high water level events is still poor. In this study, the zoning matching approach (ZMA) is used in ANN to accurately monitor flood events in real time by focusing the development of the forecasting model on high water level zones. ZMA is a trial and error approach, where several training datasets using high water level data are tested to find the best training dataset for forecasting high water level events. The advantage of ZMA is that relevant knowledge of water level patterns in historical records is used. Importantly, the forecasting model developed based on ZMA successfully achieves high accuracy forecasting results at 1 to 3 h ahead and satisfactory performance results at 6 h. Seven performance measures are adopted in this study to describe the accuracy and reliability of the forecasting model developed.
