Acanthamoeba spp. boleh menyebabkan keratitis kepada manusia, khasnya kepada pemakai kanta sentuh yang tidak menitikberatkan aspek higen kanta sentuh. Kajian ini bertujuan untuk mengkaji keberkesanan antibiotik titisan mata Gentamicin terhadap sista Acanthamoeba isolat klinikal iaitu HKL 5, HKL 11, HKL 32, dan HKL 51. Kajian dimulakan dengan melakukan suspensi sista terhadap keempat-empat isolat klinikal tersebut. Mikropencairan terhadap antimikrob dilakukan dan kemudiannya suspensi sista ditambah, seterusnya dieramkan selama 24 jam pada 30ºC sebelum dipindahkan ke atas plat agar bukan nutrien (NNA) yang dilapisi E. coli matian haba. Plat agar diperhatikan setiap hari sehingga hari yang ke-14 untuk mengesan sebarang kehadiran trofozoit di bawah mikroskop inverted. Kehadiran trofozoit Acanthamoeba menunjukkan bahawa antibiotik ujian tidak berkesan terhadap sista Acanthamoeba. Gentamicin berkesan terhadap sista Acanthamoeba, dengan nilai purata sistisidal minimum (MCC) 1453.1 μg/ml. Ge.....

The detection of halal adulteration in processed food, particularly the presence of porcine based material, be it human or animal food is very important to safeguard the interest of Muslim consumers. Many techniques have been developed to determine such adulteration which can ascertain the halal status of food products. In this paper, the presence of porcine based materials in few processed foods namely meat products, candy products, and animal feeds obtained from Kota Samarahan, Sarawak, Malaysia were screened by using Polymerase Chain Reaction (PCR) method. Findings revealed that all processed meat samples showed a positive result of the presence of porcine DNA. A similar result was also obtained for a few samples of animal feeds and candy products. As such, further study is required to verify the results...

A wealth of studies have proposed that plantations can be enhanced into an area that is rich in biodiversity, perhaps to the extent of being an off-reserve strategy area for conservation purposes. This study was carried out to evaluate the effectiveness of rubber forest plantation in harbouring and acting as an off-reserve conservation area for birds. By conserving forest fragment areas as a way to improve the heterogeneity of a landscape within a rubber forest plantation, this paper aims to determine the conservation status of birds recorded from Bukit Kuantan rubber forest plantation which adopted forest fragment conservation. A point count observation method was implemented to record any sightings of birds within this plantation landscape. Subsequently, the identified bird species were checked with the Malaysian Wildlife Conservation Act (WCA) 2010 and IUCN Red List Data of endangered species. From the context of WCA 2010, it was found that majority of birds which accounted to 70%, .....

In the evolving globalization in Malaysia, many organizations employ online communication platform for faster decision making, easier collaboration on assignments and greater recognition of employees for achievement and rewards. However, this additional medium of communication posts a risk of uncivil online comments that can lead to lower unproductively among employees that reduces employees’ well-being and increases organizations costs. Therefore, this paper aims to explore the negative consequences of online incivility, in particular in Malaysia, considering aspect of negative moods as possible mediator in the relationship. In addition, problem solving conflict management styles is also discussed as a social support that may decrease the negative consequences of online incivility based from sound literature review. Plausible hypotheses are also then derived from the constructive arguments. This study is consistent with the objectives of Eleventh Malaysian Plan (2016-2020) and Trans.....

From the agricultural waste of rice (rice husk), high purity SiO2 with about 98.548 % purity was extracted using a very simple room temperature leaching method. Using the rice husk extracted silicate, a system of silicate borotellurite glasses was fabricated with composition equation [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x= 0.0, 0.1, 0.2, 0.3 and 0.4. The density and molar volume were measured, and Fourier transform infrared (FTIR), X-ray diffraction (XRD) and UV-Vis analyses were performed on the glasses. Both the density and molar volume decreased and the XRD pattern confirmed the glasses’ amorphous nature. The FTIR showed the presence of TeO3, TeO4, BO3, BO2O, SiO4, and H3BO3 structural units in the glasses. The concentrations of TeO3, TeO4, BO3 and BO2O structures were determined by the deconvolution of the FTIR spectra using an Origin software. The optical energy band gap, index of refraction, oxygen packing density (OPD), molar refractive index, metallization criterion and pola.....

This study was conducted to examine the effects of the level of concerns among Perlis Silat athletes before the Sukma competition. The study focuses on the level of anxiety among the Perlis Silat athlete before the Sukma tournament. This study found that Silat athletes showed the highest result of anxiety. Moreover, the main objective of this study is to determine the different levels of trait anxiety seven days before the game, one day before the match and 30 minutes before the game. This study is significant to martial arts athletes in addition to being a reference to Silat Association of Perlis and other sports agencies in Perlis. The researchers aim to examine the anxiety level among the athletes who participated in the Perlis Sukma competition. 17 Perlis martial arts athletes aged 18-21 were chosen as subjects .The SCAT (Sport Anxiety Test) questionnaire was used in this study. The subjects were given a questionnaire that was distributed seven days before a game, one day before th.....

Penyelidikan yang dilakukan bertujuan mensintesis, mengformulasi dan menilai inokulan biosintetik bagi penghasilan resin gaharu. Bagi mengformulasi inokulan biosintetik, beberapa bahan digunakan termasuklah madu lebah, susu segar, sukros, air kelapa, dan kulat Fusarium solani yang diadun dengan menggunakan sukatan tertentu. Inokulan biosintetik diformulasi di makmal Biologi, Fakulti Sains dan Matematik, UPSI. Inokulan biosintetik yang diformulasi diuji terhadap tujuh batang pokok gaharu di Slim River, Perak dengan teknik suntikan lubang bor, suntikan titisan mata, dan sapuan. Hasil resin gaharu dituai dalam tempoh enam bulan dari tarikh suntikan. Sampel resin gaharu dipungut diuji di makmal Kimia, FSM, UPSI. Kualiti resin gaharu dianalisis dengan teknik Kromatografi Gas Spektrometri Jisim (GCMS). Parameter kualiti resin gaharu yang diamati adalah warna dan keharuman. Manakala populasi Fusarium solani dalam inokulan biosintetik dianggar dengan menggunakan model statistik Verhulst. Dapat.....

Cassia tora is a leguminous plant belonging to the family Fabaceae and are used for the treatment of lepsory, psoriasis, ringworm, ulcers, skin diseases and as a laxative and antiasthenic. The preliminary phytochemical screening of the ethanolic extract of Cassia tora was carried out using standard methods while the nutritional values were studied for moisture content, ash content, crude lipids, crude fibre, crude protein and carbohydrates. The preliminary phytochemical analysis of the leaves indicated the presence of anthraquinones, flavonoids, steroids/triterpenoids, fats, tannins, alkaloids, carbohydrates, phlobatannins and glycosides. The proximate analysis of the leaves revealed that it contained crude fat 6.01%, crude fibre 7.54%, moisture 10.23%, ash content 15.01%, crude protein 27.34% and carbohydrate 33.69%. Cassia tora leaves could be a potential source of nutritional and mineral elements that may be useful in nutrition. The phytochemicals observed in this study explained th.....
