Effect of eucation level and religion on attitude to stem cells in Malaysia
The issue of using stem cells derived from human embryos and adult tissues to treat diseases has been divisively debated mainly due to ethical concerns. The objective of this article was to assess and compare the attitude level of the Malaysian public in the Klang Valley region towards human adult stem cells (hASCs) and human embryonic stem cells (hESCs). Results of the survey on 509 adult respondents revealed that the Malaysian public expressed higher support for hASCs, perceived the application as having lower moral concern and more acceptable by their religion as compared to hESCs. Univariate analysis following Multivariate Analysis of Variance (MANOVA) confirmed that there were significant differences for perceived benefits and religious acceptance of hASCs across education level. Respondents who hold tertiary education level tended to perceive both hESCs and hASCs as more beneficial and believed the applications as more acceptable from their religious point of view. Their opinion of hASCs differed significantly compared to the respondents who hold pre-university education. Respondents from all religions perceived both hESCs and hASCs as having moderate benefits and risks. Significant differences were only detected for perceived moral concerns and encouragement of hESCs across religion. The Christians expressed greater moral concern of both hESCs and hASCs compared to other religions but post hoc test only detected significant difference in their opinion on hESCs from the Buddhists. The Buddhists were found to be more supportive towards both hESCs and hASCs but their support level for hESCs only differed significantly from the Muslims
Sikap pihak berkepentingan terhadap kecukupan peraturan dalam undang-undang biokeselamatan di Malaysia
Malaysia telah mengenal pasti bioteknologi sebagai salah satu daripada lima teknologi utama yang mampu menjadi pemacu
transformasi Malaysia ke arah negara perindustrian menjelang 2020. Namun begitu, pembangunan yang pesat dalam bidang ini
telah mendatangkan kebimbangan masyarakat, lebih-lebih lagi yang melibatkan isu biokeselamatan. Di Malaysia, Akta
Biokeselamatan 2007 telah diluluskan pada 11 Julai 2007 dan dikuatkuasakan pada 1 Disember 2009 untuk mengawal selia
bioteknologi moden dan hasilannya. Namun terdapat kritikan yang mengusulkan beberapa kekurangan peraturan dalam akta ini
berkaitan aspek bioetika dan sosioekonomi. Justeru penilaian kecukupan peraturan yang sedia ada untuk memastikan keselamatan
penggunaan bioteknologi dan hasilannya, perlu dilakukan. Kajian ini bertujuan untuk menilai tahap kepercayaan terhadap pihak
kerkeutamaan, keterlibatan pihak berkepentingan dalam aktiviti kawal selia, dan sikap terhadap kecukupan peraturan biokeselamatan
di Malaysia. Sehubungan dengan itu, satu set soal selidik telah diedarkan kepada 451 orang responden yang terdiri daripada
pelbagai pihak berkepentingan di Lembah Klang. Penganalisisan data dilakukan dengan menggunakan program SPSS versi
18.0. Hasil kajian menunjukkan bahawa tahap keterlibatan pihak berkepentingan dalam aktiviti kawal selia adalah rendah dan
tahap kepercayaan terhadap pihak berkeutamaan sebagai sederhana. Pihak berkepentingan menilai kecukupan struktur kawal
selia, kecukupan penilaian dan pengurusan risiko, pengambilkiraan prinsip penting dalam Akta Biokeselamatan 2007, kecukupan
denda, kecukupan hebahan umum dan sikap keseluruhan terhadap biokeselamatan sebagai sederhana
Transportation and acclimation optimisation of wild marble goby (Oxyeleotris marmorata Bleeker, 1852)
The Marble goby (Oxyeleotris marmorata Bleeker) is usually found in freshwater bodies. Due to its high commercial value and demand, it is farmed in cages and pond systems. Marble goby fish are preferred to be freshly killed and processed upon request in Asian restaurants. Currently, there are some challenges faced by fishermen who wish to transport live fish to restaurants or markets due to the traditional method of using water tanks as carriers. These water tanks are usually very heavy and bulky, increasing transportation costs. Furthermore, coping with the survivability of fish post-transportation has proven to be a challenge. This study was aimed at investigating the semi-dry method for fish transport and acclimatization of fish after transport in different tank sizes. In the semi-dry, where fish were covered using a towel transportation method where the survival rate at ~92%. For the acclimation experimental group, stream water was found to be the most appropriate type of water for rearing the marble goby fish, which demonstrated a conspicuous survivability rate of ~83%. whereas, for adaptation, marble goby fish from the wild had a faster adaptation rate in smaller spaces like aquariums as compared to large ‘stock tanks.’ To the best of our knowledge, this is the first study that will provide a better understanding of the transportation method, acclimation conditions, and habitat that can lead to a reduction in the mortality rate during the marble goby transit processes

ISSUES IN BIOTECHNOLOGY TEACHING - A nationwide biotechnology outreach and awareness program for Malaysian high schools
Biotechnology education in developing nations remains one of the rate
limiting factors in achieving optimal human resource capacity to drive
and tap the bio-resources of these nations. Many developing countries
are situated within rich bio-diversity enclaves. Biotechnology offers
the promise of tapping these bio resources towards due process of
developing these nations. While there may be a steady stream of biology
and biotechnology based graduates, from Malaysian as well as foreign
universities contributing to the human resource base for these
countries, the numbers and knowledge diversity produced, still lack the
capacity to optimally power research and development as well as supply
the industrial biotechnology sectors of these countries. Realizing the
need to address these issues at the grassroots level of higher
education, Malaysia has taken an active step of bringing biotechnology
into the classrooms of high schools throughout the country. These
future generations of Malaysians, are hoped to progress towards manning
and driving Malaysia's BioValley initiatives (a biotech based R&D
and industry cluster), towards the national dream of developed nation
status by the year 2020, using biotechnology as an economic growth
vehicle. Here, we share our experiences in developing and proliferating
a biotechnology awareness program for Malaysian high schools. It is
hoped that similar programs will strive towards similar objectives in
other developing countries
Construction of molecule markers for prolific oil palm tissue culture
The use of DNA marker could minimize problems in tissue culture especially when applied during the selection of plants for tissue culture. Therefore, the aimed of this research was to develop molecular markers for prolific oil palm tissue culture using amplified fragment length polymorphism (AFLP) technique. AFLP analysis was carried out upon 20 oil palm clones that have divided into three classes which are non-prolific clone (10 types of clone), normal clone (6 types of clone) and prolific clone (4 types of clone). All of the clones used were from different cell line. There were 25 primer combinations used in the AFLP analysis and 13 out of them have produced significant polymorphic amplification patterns. From these results, 44 polymorphic DNA fragments were isolated where 33 fragments for non-prolific clone, one fragment for normal clone and 10 fragments for prolific clone. These fragments were cloned into plasmid, sequenced and then sequence analysis was done. There were 36 polymorphic fragments have undergone the subsequent experiments. A pair of specific primers for each fragment was designed based on their sequences. The expected size of amplified DNA bands for each primer pair was between 70 bp to 500 bp. The optimized primer pairs were tested to the 20 types of oil palm clones in order to confirm the markers developed. From the 36 designated primers combinations, 2 pairs of the primers showed the potential to be used as marker for prolific oil palm tissue culture

Short Communication Cloning of a Partial β-glucosidase Gene From Aspergillus terreus SUK-1
Abstract The breakdown of cellulose to glucose is catalysed by a complex cellulase enzyme which is comprised of three classes of enzymes; endoglucanase, exoglucanase and β-glucosidase. Many studies have been done on cellulase and several genes encoding for β-glucosidase have been reported. Here we describe the cloning and sequence analysis of partial putative β-glucosidase gene from Aspergillus terreus SUK-1. Its potential to produce cellulase enzyme has been studied and reported. A pair of specific primer was designed from the conserved regions of several fungal sequences taken out from the GenBank. PCR amplification has successfully amplified a DNA fragment of approximately 233 bp and this fragment was cloned (designated as SA3). The sequence analysis with BLAST showed high similarity towards β-glucosidase gene and protein. 80% and 79% homology were observed between SA3 nucleotide sequence and β-glucosidase gene of A. niger and both A. kawachii and A. aculeatus. Whereas, amino acid sequence of SA3 showed 83% homology towards β-glucosidase of A. niger, A. kawachii and A. aculeatus
