The Impact of Equal Employment Opportunity-Affirmative Action in U.S. and New Economic Policy in Malaysia on Employment and Reverse Discrimination

Penggubalan polisi Equal Employment Opportunity-Affirmative Action (EEO-AA) bertujuan memastikan wujud keseimbangan peluang pekerjaan di antara kaum majoriti dan minoriti di Amerika Syarikat. Di Malaysia pula, Dasar Ekonomi Baru (DEB)diwujudkan bagi menyeimbangkan status ekonomi di antara pelbagai etnik. Kajian ini pertamanya bertujuan untuk menganalisis sejauhmana EEO-AA dan DEB dapat mencapai matlamat untuk menyeimbangkan peluang pekerjaan di Amerika Syarikat dan juga status ekonomi antara etnik di Malaysia. Keduanya, untuk menganalisis sama ada EEO-AA dan DEB ini menyebabkan berlakunya “reverse discrimination”. Hasil kajian mendapati EEO-AA hanya memberi impak yang kecil kepada golongan minoriti di Amerika Syarikat. Di Malaysia pula, DEB telah berjaya meningkatkan jumlah partisipasi Bumiputera di dalam pelbagai sektor. Manakala kedua-dua polisi tidak menyebabkan berlakunya “reverse discrimination”

A Profile Analysis of Potential Investors in Ireit Waqf Investment Products

The objective of this study is to provide a profile analysis of potential investors in iREIT as an instrument for waqf asset development. By adopting a survey questionnaire approach, a total of 365 respondents participated in the survey, which assessed information pertaining to the understanding of iREIT as an investment instrument, level of acceptance towards the idea of its introduction in the context of waqf, the medium of promotion and collection that they most prefer, the suitable price, and the unique features that they agreed to have in this hybrid iREIT. The results suggest that majority of the respondents are interested to participate as investors rather than donors, indicating that greater amount of funds can be tapped from the issuance of the iREITs waqf if these preferences of the investors are given priority. Findings of this study would assist in the formulation of an innovative investment structure based on iREIT waqf that is both practical and appealing to the widest pool of investors, and further contribute towards the development of the waqf sector.     Keywords: Waqf, iREITs, investment, profiling, Islamic financ

Control of Glycogen Content in Retina: Allosteric Regulation of Glycogen Synthase

Retinal tissue is exceptional because it shows a high level of energy metabolism. Glycogen content represents the only energy reserve in retina, but its levels are limited. Therefore, elucidation of the mechanisms controlling glycogen content in retina will allow us to understand retina response under local energy demands that can occur under normal and pathological conditions. Thus, we studied retina glycogen levels under different experimental conditions and correlated them with glucose-6-phosphate (G-6-P) content and glycogen synthase (GS) activity

The Development of a Point of Care Clinical Guidelines Mobile Application Following a User-Centred Design Approach

This paper describes the development of a point of care clinical guidelines mobile application. A user-centred design approach was utilised to inform the design of a smartphone application, this included: Observations; a survey; focus groups and an analysis of popular apps utilised by clinicians in a UK NHS Trust. Usability testing was conducted to inform iterations of the application, which presents clinicians with a variety of integrated tools to aid in decision making and information retrieval. The study found that clinicians use a mixture of technology to retrieve information, which is often inefficient or has poor usability. It also shows that smartphone application development for use in UK hospitals needs to consider the variety of users and their clinical knowledge and work pattern. This study highlights the need for applying user-centred design methods in the design of information presented to clinicians and the need for clinical information delivery that is efficient and easy to use at the bedside

Regulation of GSK-3 Activity as A Shared Mechanism in Psychiatric Disorders

Serin/Treonin kinaz ailesinin üyelerinden bir kinaz olarak ilk kez glikojen sentaz’ı inhibe ettiği keşfedilen glikojen sentaz kinaz-3 (GSK-3), günümüzde bilinen 50’den fazla substratı ile birçok hücre içi düzenleyici mekanizmada görev alan geniş etki spektrumlu bir enzim olarak kabul edilmektedir. GSK-3’ün memelilerde GSK-3α ve GSK-3β olmak üzere yapısal olarak yüksek homoloji gösteren iki izoformu bulunmaktadır. Her iki izoform birçok dokuda yaygın dağılım göstermekle beraber, en yüksek oranda beyinde bulunmakta ve genellikle benzer fonksiyonlar göstermektedirler. Diğer protein kinazların aksine GSK-3 uyarılmamış hücrede yapısal olarak aktif yani defosforile halde bulur. Protein kinaz A (PKA), protein kinaz B (PKB;AKT) ve protein kinaz C (PKC) gibi diğer protein kinazlarla fosforilasyona uğrayarak olarak inaktive edilir. Günümüzde artmış GSK-3 aktivitesinin major depresyon, bipolar bozukluk, hiperaktivite bozuklukları gibi hastalıklar ve şizofreni oluşumunda rol oynayabileceğine ilişkin önemli bulgular mevcuttur. Bu nedenle söz konusu psikiyatrik hastalıklarda arttığı gösterilen GSK-3 aktivitesinin azaltılmasının tedavide umut verici bir yaklaşım olabileceği kabul edilebilir. Bu gözden geçirme çalışmasında yukarıda sözü edilen psikiyatrik hastalıkların oluşmasında görev alan GSK-3 aracılı mekanizmalara kısaca değinilerek GSK-3’ün aktivitesinin düzenlenmesinde rol oynadığı gösterilen klinikte kullanılan ilaçlara yer verilmiştir.

Involvment of Cytosolic and Mitochondrial GSK-3β in Mitochondrial Dysfunction and Neuronal Cell Death of MPTP/MPP+-Treated Neurons

Aberrant mitochondrial function appears to play a central role in dopaminergic neuronal loss in Parkinson's disease (PD). 1-methyl-4-phenylpyridinium iodide (MPP+), the active metabolite of N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), is a selective inhibitor of mitochondrial complex I and is widely used in rodent and cell models to elicit neurochemical alterations associated with PD. Recent findings suggest that Glycogen Synthase Kinase-3β (GSK-3β), a critical activator of neuronal apoptosis, is involved in the dopaminergic cell death. In this study, the role of GSK-3β in modulating MPP+-induced mitochondrial dysfunction and neuronal death was examined in vivo, and in two neuronal cell models namely primary cultured and immortalized neurons. In both cell models, MPTP/MPP+ treatment caused cell death associated with time- and concentration-dependent activation of GSK-3β, evidenced by the increased level of the active form of the kinase, i.e. GSK-3β phosphorylated at tyrosine 216 residue. Using immunocytochemistry and subcellular fractionation techniques, we showed that GSK-3β partially localized within mitochondria in both neuronal cell models. Moreover, MPP+ treatment induced a significant decrease of the specific phospho-Tyr216-GSK-3β labeling in mitochondria concomitantly with an increase into the cytosol. Using two distinct fluorescent probes, we showed that MPP+ induced cell death through the depolarization of mitochondrial membrane potential. Inhibition of GSK-3β activity using well-characterized inhibitors, LiCl and kenpaullone, and RNA interference, prevented MPP+-induced cell death by blocking mitochondrial membrane potential changes and subsequent caspase-9 and -3 activation. These results indicate that GSK-3β is a critical mediator of MPTP/MPP+-induced neurotoxicity through its ability to regulate mitochondrial functions. Inhibition of GSK-3β activity might provide protection against mitochondrial stress-induced cell death

Multifaceted roles of GSK-3 and Wnt/β-catenin in hematopoiesis and leukemogenesis: opportunities for therapeutic intervention

Glycogen synthase kinase-3 (GSK-3) is well documented to participate in a complex array of critical cellular processes. It was initially identified in rat skeletal muscle as a serine/threonine kinase that phosphorylated and inactivated glycogen synthase. This versatile protein is involved in numerous signaling pathways that influence metabolism, embryogenesis, differentiation, migration, cell cycle progression and survival. Recently, GSK-3 has been implicated in leukemia stem cell pathophysiology and may be an appropriate target for its eradication. In this review, we will discuss the roles that GSK-3 plays in hematopoiesis and leukemogenesis as how this pivotal kinase can interact with multiple signaling pathways such as: Wnt/β-catenin, phosphoinositide 3-kinase (PI3K)/phosphatase and tensin homolog (PTEN)/Akt/mammalian target of rapamycin (mTOR), Ras/Raf/MEK/extracellular signal-regulated kinase (ERK), Notch and others. Moreover, we will discuss how targeting GSK-3 and these other pathways can improve leukemia therapy and may overcome therapeutic resistance. In summary, GSK-3 is a crucial regulatory kinase interacting with multiple pathways to control various physiological processes, as well as leukemia stem cells, leukemia progression and therapeutic resistance. GSK-3 and Wnt are clearly intriguing therapeutic targets

Biomedical informatics and translational medicine

Biomedical informatics involves a core set of methodologies that can provide a foundation for crossing the "translational barriers" associated with translational medicine. To this end, the fundamental aspects of biomedical informatics (e.g., bioinformatics, imaging informatics, clinical informatics, and public health informatics) may be essential in helping improve the ability to bring basic research findings to the bedside, evaluate the efficacy of interventions across communities, and enable the assessment of the eventual impact of translational medicine innovations on health policies. Here, a brief description is provided for a selection of key biomedical informatics topics (Decision Support, Natural Language Processing, Standards, Information Retrieval, and Electronic Health Records) and their relevance to translational medicine. Based on contributions and advancements in each of these topic areas, the article proposes that biomedical informatics practitioners ("biomedical informaticians") can be essential members of translational medicine teams
