Psychological impact on football players performance
The purpose of this study is to determine the psychological strength among football players. There were a total of (n=90). Psychological strength dimension consists of self-confidence, motivational control, and focus control. The data analyses were conducted using structural equation modeling (SEM) via AMOS (Analysis of Moment Structures) software package Version 20.0. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to validate the scales. The results shown that social support from parents, coach, friends and the sports agencies directly contribute towards overall social support which in turn, has significant relationships self-confidence, task orientation and ego orientation. In future research, a longitudinal study would be particularly useful to observe the model changes from one phase of footballers or any other sports performance by applying the model.Keywords: psychological strength; football players; performanc
Screening of Neonatal UK Dried Blood Spots Using a Duplex SMN1 Screening Assay
Spinal muscular atrophy (SMA) is an autosomal inherited neuromuscular genetic disease caused, in 95% of cases, by homozygous deletions involving the SMN1 gene exon 7. It remains the leading cause of death in children under 2 years of age. New treatments have been developed and adopted for use in many countries, including the UK. Success of these treatments depends on early diagnosis and intervention in newborn babies, and many countries have implemented a newborn screening (NBS) or pilot NBS program to detect SMN1 exon 7 deletions on dried blood spots. In the UK, there is no current NBS program for SMA, and no pilot studies have commenced. For consideration of adoption of NBS for a new condition, numerous criteria must be satisfied, including critical assessment of a working methodology. This study uses a commercially available real-time PCR assay to simultaneously detect two different DNA segments (SMN1 exon 7 and control gene RPP30) using DNA extracted from a dried blood spot. This study was carried out in a routine clinical laboratory to determine the specificity, sensitivity, and feasibility of SMA screening in a UK NBS lab setting. Just under 5000 normal DBSs were used alongside 43 known SMA positive DBSs. Study results demonstrate that NBS for SMA using real-time PCR is feasible within the current UK NBS Laboratory infrastructure using the proposed algorithm
Sociodemographic characteristics, clinicopathological parameters and survival among Malaysians with oral squamous cell carcinoma (OSCC)
Introduction: Western researchers showed that oral squamous cell carcinoma (OSCC) patients exhibit lower survival rate and poorer prognosis compared to other type of cancer where several clinicopathological parameters have been implicated in the survival of patients. This study aims to assess the association between sociodemographic and clinicopathological parameters with survival of OSCC patients.
Method: Data were collected from 253 histologically diagnosed OSCC patients attending selected clinics nationwide. Survival was analyzed for relation with habits, site, disease stage and nodal involvement.
Results: Mean age was 58.9 ± 12.6 years with 8.3% aged less than 40. Majority is females (61.1%) and of Indian ethnic (48.0%). Most common habit was quid chewing (55.8%), followed by smoking (29.7%) and most came at stage IV (44.3%). Tongue was the most common site (38.9%), followed by buccal mucosa (35.0%). Factors associated with survival are smoking (p = 0.016), stage at presentation (p < 0.001) and nodal involvement (p < 0.001).
Discussion: Majority of OSCC cases occurred among Indians where the patients were quid chewers and presents with advanced cancer. Survival of patients decreased steadily over the years. At 1 year after diagnosis, 67.2% was still alive but only 13.4% survived 5 years. Among the habits studied, only smoking was found to be associated with survival where among those smoking, only 38.7% is alive compared to 61.3% deceased. No association was found between site and survival. A highly significant association was seen for both cancer stage and nodal involvement with survival. More survivors were found among those who come at early stage (76.3%) compared to late stage (32.7%). Similarly, more than two thirds (69.1%) of those who present with negative nodal involvement were found to be alive. In conclusion, smoking, disease stage and nodal status are predictors of survival for OSCC patients in Malaysia.

Microwave Reflection Based Dielectric Spectroscopy for Moisture Content in Melele Mango Fruit (Mangifera Indica L.)
The Melele mango is one of the special local fruit Malaysia and it has high commercial value. However, the current methods are not efficient in determining optimum period to harvest. The optimum harvest time has close relationship with moisture content in fruit. The reflection based dielectric spectroscopic technique is conducted to measure moisture in Melele mango fruits. Dielectric and reflection measurements were conducted over a frequency range from 200 MHz to 8 GHz on clone Melele mango. Dielectric constant, loss factor and complex reflection coefficient of Melele mango with different moisture content were measured using an Agilent E8362B PNA Network Analyzer in conjunction with an Agilent 85070E High Temperature Probe over a frequency range from 200 MHz to 8 GHz. The measured reflection coefficient is presented in magnitude and phase. Dielectric constant and loss factor decreases when the moisture content in mango fruit decreases. The magnitude of the reflection coefficient descends due to increment of the dielectric constant. The results show that the measured dielectric properties and complex reflection coefficient provides the ability to predict fruit moisture content
Ocular inflammatory disease and ocular tuberculosis in a cohort of patients co-infected with HIV and multidrug-resistant tuberculosis in Mumbai, India: a cross-sectional study.
The prevalence and the patterns of ocular inflammatory disease and ocular tuberculosis (TB) are largely undocumented among Multidrug Resistant TB (MDR-TB) patients co-infected with Human Immunodeficiency Virus (HIV) and on antituberculosis and antiretroviral therapy (ART)
Oral cancer and precancer research in Malaysia - the database and tissue resource bank
Introduction: Uncoordinated data collection by different research groups prompted the initiation of Malaysian oral cancer Research Initiative (MOCRI) group. Objectives: To coordinate and standardize data and tissue collection and storage, develop a minimum dataset on risk factors, intervention techniques and quality of life of oral cancer patients. Materials and Methods: A computer software programme is currently being developed to accommodate multi-centre data collection and research activities in eight hospitals. The complete dataset includes parameters on sociodemographic, clinical, pathological, quality of life measures, details of treatment methods, vital status and dietary intake. Tissues are being collected, stored and catalogued as fresh and formalin-fixed tissues for future use in satellite researches. The networking in tissue and data collection includes the establishment of oral cancer cell-lines. These tissues are being planned for studies on genetic profile, genetic polymorphism, diagnostic and prognostic markers. Results: Tissues and data on 115 oral cancers, 9 leukoplakia and 13 lichen planus has been collected since 2003. Preliminary data from 2004 were analysed for 58 cancer patients. Majority of them are more than 60 years old (65.5%) with a mean age of 63.3. Twenty-four (41.4%) were males, 34 (58.6%) females with the majority of them being Indians (56.9%) followed by Chinese and Malays (15.5% each), Indigenous people of Sabah and Sarawak (12.1%). Eighteen (31%) respondents were smokers, 17 (29.3%) alcohol drinkers and 31 (53.4%) betel quid chewers. Five patients have had histories of family cancers where 3 included immediate family members with head and neck cancers. For the quality of life measure, only 30.2% felt that their daily activities were disrupted despite having advanced cancers. Satellite researches are in progress on genetic polymorphism and tumour markers. One oral cancer cell-line has been established. Conclusion: The establishment of oral cancer database and tissue bank in encouraging and supports on-going satellite researches. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down
The Epoxygenases CYP2J2 Activates the Nuclear Receptor PPARα In Vitro and In Vivo
Peroxisome proliferator-activated receptors (PPARs) are a family of three (PPARalpha, -beta/delta, and -gamma) nuclear receptors. In particular, PPARalpha is involved in regulation of fatty acid metabolism, cell growth and inflammation. PPARalpha mediates the cardiac fasting response, increasing fatty acid metabolism, decreasing glucose utilisation, and is the target for the fibrate lipid-lowering class of drugs. However, little is known regarding the endogenous generation of PPAR ligands. CYP2J2 is a lipid metabolising cytochrome P450, which produces anti-inflammatory mediators, and is considered the major epoxygenase in the human heart.Expression of CYP2J2 in vitro results in an activation of PPAR responses with a particular preference for PPARalpha. The CYP2J2 products 8,9- and 11-12-EET also activate PPARalpha. In vitro, PPARalpha activation by its selective ligand induces the PPARalpha target gene pyruvate dehydrogenase kinase (PDK)4 in cardiac tissue. In vivo, in cardiac-specific CYP2J2 transgenic mice, fasting selectively augments the expression of PDK4.Our results establish that CYP2J2 produces PPARalpha ligands in vitro and in vivo, and suggests that lipid metabolising CYPs are prime candidates for the integration of global lipid changes to transcriptional signalling events
