Activity pattern, energy expenditure and energy intake among male athletes during a training and no training days
Wan Nudri Wan Daud
Physical activity has long been recognized as an important factor in enhancing health and reducing the risk of various chronic diseases. This study aimed to determine the physical activity pattern, total energy expenditure (TEE) and daily energy intake (EI) of a sample of male athletes on a training and no training days, and to compare with non-athletes. The subjects comprised 83 male athletes from various types of sports (athlete group), and 80 inactive men (non-athlete/ control group) aged 18 to 44 years. The TEE of subjects was calculated based on their daily activity. The basal metabolic rate (BMR) was calculated for all subjects based on body weight using the predictive equations of a previous locaI study. Physical activity level (PAL) was calculated as the ratio of TEE to BMR. The energy intake (EI) was obtained using a one day 24-hour diet recall. During a normal day, the mean TEE (2,272 kcal/day) and EI (2,461 kcal/day) of the athletes were not significantly different compared .....

Prevalance and risk factors of Entamoeba species infections among Orang Asli school children in Perak
Nur Insyirah Tokijoh
This study aims to investigate the molecular epidemiology and risk factors of Entamoeba histolytica, Entamoeba dispar, and Entamoeba moshkovskii infection among Orang Asli school children in Perak. Stool samples were collected from 544 school children and the DNA extracted were amplified using nested multiplex PCR. The univariate and multivariate regression analyses were then used to determine the risk factor associated with Entamoeba species infection. The overall prevalence of Entamoeba complex infections was 21.3% (116/544). The total of school children infected with E. moshkovskii was 10.7% (58/544) followed by 9.0% (49/544) of E. dispar and 5.0% (27/544) of E. histolytica. One sample was positive for the mixed E. histolytica and E. dispar infection, five samples were positive for the mixed E. histolytica and E. moshkovskii infection, and 12 samples were positive for the mixed E. dispar and E. moshkovskii infection. As a result of the univariate analysis, there were 19 .....

Profil daya-halaju dan komponen kecergasan fizikal pemain Sepak Takraw wanita elit
Rahayu Che Romli
Keperluan komponen kecergasan adalah berbeza bergantung kepada jenis sukan yang dipraktikkan. Tujuan kajian ini dijalankan untuk mengenalpasti komponen kecergasan dominan bagi pemain sepak takraw wanita elit. Kajian ini menggunakan dua kaedah analisis iaitu melalui rakaman video perlawanan dan pengukuran prestasi countermovement jump (CMJ) pemain. Analisis rakaman video dilakukan terhadap perlawanan sepak takraw semasa Sukan SEA 2019 melibatkan empat buah negara. Manakala pengukuran prestasi CMJ pemain melibatkan lapan orang pemain wanita elit SUKMA Perak. Analisis dilakukan untuk mendapatkan jumlah ulangan penggunaan komponen kecergasan yang dilakukan semasa pertandingan manakala pengukuran prestasi CMJ dilakukan untuk mendapatkan profil daya-halaju pemain. Hasil dapatan kajian mendapati komponen kecergasan dominan bagi pemain sepak takraw wanita elit ialah kuasa (M = 56.00 + 4.97) dan masa reaksi (M = 56.00 + 13.44). Dapatan kajian komponen kecergasan dominan bagi posisi .....

The detection of phytochemical properties from freeze dried Ottochloa nodosa (Kunth) Dandy Extracts and its potential as a bacterial inhibitor
Norshahidah Abd Latib
This study aimed to detect the secondary metabolites and chemical components in the freeze-dried extract of Ottochloa nodosa (Kunth) Dandy. In addition, discovering the extract could have potential as a bacterial inhibitor by determination of the minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) carried out in extracts. Determination of antimicrobial potential of freeze-dried extracts was conducted through phytochemical screening, gas chromatography-mass spectrometry (GC-MS) test, agar disc diffusion and broth dilution methods. The study shows this extract has bacterial inhibitors’ potential since it contained phytochemical compounds such as alkaloid, saponin, flavonoid and tannin, while 9 chemical components have been displayed through GC-MS analysis. The disc diffusion method was done at different concentrations, at 25, 50 and 100 mg/ml. The result also shows that the extracts are able to inhibit the gram-positive and gram-negative bacteria. Freeze.....

Plant dispersal mode at different urbanization levels in Ipoh City Council, Perak
Balqis Aqila Alue
Urbanization is rapidly expanding, and many forests are being cleared. The loss of crucial ecological functions, including dispersal and pollination, in urban settings can have detrimental effects on individual species and the sustainability of entire ecosystems. Nevertheless, how urbanization affects seed dispersal is still largely unexplored. Hence, this study aimed to investigate the association between plant dispersal mode and urbanization intensity in Ipoh City Council, Perak. The percentage of built-up area within a 1km2 area was measured using ArcGIS software to establish the urbanization gradient. To reflect distinct urbanization, a total of 12 sampling plots, with the sized of 1km2 for each plot were designed. 40 subplots were randomly selected in each plot to create a complete sampling site of 0.1 hectare, and any plants discovered in the subplots were identified at the species level. To characterize the mode of dispersion for each plant species recorded, a few reports from l.....

Metabolites profiling and fingerprinting of the ethanolic extract of Zingiber zerumbet (L.) Roscoe ex Sm.
Nur Zahratun Najah Mohd Razali
Zingiber zerumbet (L.) Roscoe ex Sm. is a herbaceous medicinal plant from the Zingiberaceae family. Previous studies have mainly focused on the essential oils of the plant with little attention to its secondary metabolites. LCMS-Orbitrap is used to analyze ethanolic extract of Z. zerumbet rhizome. Dereplication is a technique applied to identify chemical constituents based on their accurate mass and comparison with custom databases, Dictionary of Natural Products (DNP), and literature using an operating system named MZmine 2.53. In this study, we have identified chemical constituents related to several classes, including flavonoids, terpenoids, diarylheptanoids, terpenes, phenolic compounds, and fatty acids. Our results provide useful information for further isolation and identification of other unknown compounds and mass spectroscopy-based metabolite profiling of Zingiber species...
