Major goal of dental treatment is to eradicate the existing diseases of the oral cavity and implement preventive measures to control the spread of the diseases. Various interventions are being used to cure the dental diseases. Due to the nanostructures, high surface volume and biocompatibility, Gold nanoparticles (GNPs) have been experimented in the treatment of gum diseases, dental caries, tissue engineering, dental implantology and diagnosis of cancers. GNPs possess antifungal and antibacterial activity, hence are incorporated in various biomaterials to potentiate the effect. They also enhance the mechanical properties of materials leading to improved outcomes. They are available in different sizes and concentrations to exhibits its beneficial outcomes. These properties of GNPs make these materials as choice of fillers in biomaterials. This review aims to discuss the effect of incorporation of GNPs in several biomaterials used for dental and medical applications.
A literate and numerate population is the goal of any modern industrialized society. Literacy and mathematics skills carry the means by which children are equipped for the education processes on which their future will depend. Deaf and hard of hearing students' reading and mathematics skills are lower than that of others due to their inability. Before enhancing their literacy and mathematics skills, their standard of literacy and mathematics skills should first be identified. For this reason, the Malaysian Ministry of Education initiated the Literacy and Numeracy Screening (LINUS) program in 2009. However, problems arose in the assessment method of LINUS screening for these students since the LINUS screening method does not accommodate these students' situation and needs. Therefore, the researchers introduced internet-based Literacy and Mathematics Assessment (iLiMA) prototype that can overcome those problems. In the iLiMA prototype, sign language instruction video is used to standardize the assessment method in order to ensure that non-bias assessment could be established. The methodology used to develop this system is the Evolutionary Process Model - Prototype. The iLiMA prototype usability was assessed with the Computer System Usability Questionnaire (CSUQ) and conducted by using web-based survey method. The results indicate that the iLiMA prototype is usable and teachers are satisfied with it. Finally, the iLiMA prototype which had the potential to accommodate deaf and hard of hearing students to get a standardized and non-bias literacy and mathematics assessment was developed.
The invention of microarray technology has enabled expression levels of thousands of genes to be monitored at once. This modernized approach has created large amount of data to be examined. Recently, gene regulatory network has been an interesting topic and generated impressive research goals in computational biology. Better understanding of the genetic regulatory processes would bring significant implications in the biomedical fields and many other pharmaceutical industries. As a result, various mathematical and computational methods have been used to model gene regulatory network from microarray data. Amongst those methods, the Bayesian network model attracts the most attention and has become the prominent technique since it can capture nonlinear and stochastic relationships between variables. However, structure learning of this model is NP-hard and computationally complex as the number of potential edges increase drastically with the number of genes. In addition, most of the studies only focused on the predicted results while neglecting the fact that microarray data is a fragmented information on the whole biological process. Hence this study proposed a network-based inference model that combined biological knowledge in order to verify the constructed gene regulatory relationships. The gene regulatory network is constructed using Bayesian network based on low-order conditional independence approach. This technique aims to identify from the data the dependencies to construct the network structure, while addressing the structure learning problem. In addition, three main toolkits such as Ensembl, TFSearch and TRANSFAC have been used to determine the false positive edges and verify reliability of regulatory relationships. The experimental results show that by integrating biological knowledge it could enhance the precision results and reduce the number of false positive edges in the trained gene regulatory network.
Badminton is a court
based racquet games to be played either in single (one versus one) or double (two versus two)
in a court. Badminton is a famous sport especially in Asia and among the excellent team in
badminton includes China, Indonesia, Malaysia and South Korea. Outside of Asia, badminton
is well known in England and Denmark. One of the main tasks of strength and conditioning
coach or trainer is to design and implement physical conditioning program. Well developed
and implemented training programs mainly dependable on how accurate the training program
variables being devised and manipulated, in order to serve the need and goals of involved
athletes. Appropriate manipulation of training program variables and modifications made
from time to time relies a lot on the accuracy and reliability of monitoring assessment used.
The main purpose of this review is to identify what has been done previously regarding
physiological and biomechanical profiling of badminton players. It is also the aim of this
review to discuss on the type of test previously used in previous studies, especially with
regards to strength and power assessment, were close enough to movement pattern perform
by a badminton players during an actual badminton match.
Carbon-11 labeled radiotracers, such as 11C-acetate and
11C-palmitate are widely used in positron
emission tomography (PET) for noninvasive evaluation of myocardial metabolism under varied
physiological conditions.These tracers are attractive probes of tissue physiology, because they are
simply radiolabled versions of the native biochemical substrates. One of the major metabolites
generated by these tracers upon the administration is 11CO2 produced via the citric acid cycle. In
quantitative modeling of
11C-acetate and
11C-palmitate PET data, the fraction of blood
11C
radioactivity present as
11CO2 needs to be measured to obtain a correct radiotracer arterial
input function. Accordingly, the literature describes a method whereby the total blood
11C-activity
is counted in blood samples treated with base solution, while the fraction of
1 1CO2 is measured
after the blood is treated with acid followed by a 10 minutes gas-purge. However, a detailed
description of the experimental validation of this method was not provided. The goal of this study
was to test the reliability of a 10 minute gas purging method used to assay
11CO2 radioactivity in
blood
Pioglitazone is an anti-diabetic drug with potential to cause adverse effects following prolonged use. This study, therefore, investigated the effects of combination treatment of a subliminal concentration of pioglitazone and quercetin, a potent antioxidant, on vascular reactivity of aorta isolated from fructose-streptozotocin (F-STZ)-induced diabetic rats. Relaxation to acetylcholine and sodium nitroprusside, and contraction to phenylephrine were tested in organ bath chambers following pre-incubation with vehicle (DMSO; 0.05%), quercetin (10-7 M), pioglitazone (10-7 M), or their combination (P+Q; 10-7 M each drug). Subliminal concentration of quercetin or pioglitazone did not alter the acetylcholine- induced relaxation nor the phenylephrine-induced contraction in both normal rat and diabetic F-STZ induced tissues. However, P+Q combination synergistically improved the impaired acetylcholine-induced relaxation and decreased the elevated phenylephrine-induced contraction in aortic rings from diabetic, but not in the normal rats. Neither mono nor combination treatment altered sodium nitroprusside-induced relaxation. The combination also synergistically decreased superoxide anion and increased nitric oxide production compared to the individual treatments in aorta from diabetic rats. Overall, these data demonstrated a synergistic effect, in which, a combination (P+Q; 10-7 M each drug) caused a significantly greater effect than 10-6 M of either agent in improving endothelial function of isolated diabetic aorta. In conclusion, a combination of subliminal concentrations of pioglitazone and quercetin is able to decrease oxidative stress and provide synergistic vascular protection in type 2 diabetes mellitus and thus the possibility of using quercetin as a supplement to pioglitazone in the treatment of diabetes with the goal of reducing pioglitazone toxicity.
The implementation of the 1 Student 1 Sport Policy (D1M1S) focuses on the involvement of students who are less active in sports activities in order to polish and further developed their talent potential. It is
believed that the responsibility and the role of teachers are vital in ensuring the implementation of D1M1S conducted at the school level. However, the use of teachers as executors in ensuring that this policy is carried out must be studied and identified to achieve the goal of D1M1S besides improving the quality of work to a higher level. This study was conducted to identify the implementation level of D1M1S among teachers in secondary schools in Kluang, Johor, implementation of D1M1S based on gender differences and category of school and existing relationships such as elements of skill, understanding,
commitment and sports facilities. The key success of D1M1S implementation is closely
related to the teachers as executors. This study was carried out on 389 secondary school
teachers in Kluang, Johor. Questionnaire containing 36 items was developed and
administered to measure the elements of skill, commitment, understanding and sport
facilities. Cronbach Alpha reliability coefficient value of the instrument was 0.95. The data
were analysed using descriptive statistics (mean, standard deviation and frequency) and
inferential analysis (independent samples t-test and Pearson correlation). The findings
showed high level of understanding towards D1M1S while the elements of skill, commitment
and sports facilities were at a moderate level. In addition, there were significant difference in
terms of mean scores reported for the implementation of D1M1S based on the genders of the
teachers with the skills element (p = 0.00
Evidence suggests that breast cancer is taking the form of a chronic illness. This will add on to the present burden of managing chronic diseases in the healthcare delivery system. The burden of breast cancer being a chronic illness, calls for greater efforts to address the many neglected, physical-psycho-social and occupational functioning consequences. Timely efforts are needed to identify and implement interventions that are aim at improving the quality of life of women with breast cancer. At present, research evidence is highlighting that chronic diseases may best be managed using a self-management approach, and best treated by a balance of traditional medical care and the day-to-day practice of self-management skills. This paper presents the perspective of breast cancer as a chronic illness and its implication for rehabilitation and medical education. It is imperative that health professionals be made aware of these survivorship issues through medical education. The goals are to reduce the many disability risks, encourage patient-health provider communication and enhance partnership in care, within a timely, holistic therapeutic program to improve the quality of life of women with breast cancer.
Renal cell carcinoma (RCC) is the one of the most common type of of cancer of the kidneys affecting adults. A 35- year-old man, with Von Hippel Lindau (VHL) syndrome was referred for bilateral renal mass in a follow up CT for evaluation. Open partial left nephrectomy was performed and the final histopathological report confirmed the diagnosis. One of the most important genetic and hereditary risk factor for RCC is Von Hippel-Lindau syndrome (VHL). RCC in VHL may occur bilaterally in some cases, so preserving renal parenchymal function is a major therapeutic goal and nephron sparing surgery provides a favorable patient outcome.
Achieving and maintaining good glycaemic control remains an important goal in the management of this common and prevalent disorder. Recent evidence from important megatrials, ACCORD, ADVANCE, VADT, UKPDS-10 year follow-up as well as the STENO-2 follow-up study, have cleared doubts concerning the benefits of targeting good glycaemic control. For the first time, we have the reassurance that macrovascular benefits can be realised from good glycaemic control. The legacy effect of prior good glucose control from the UKPDS-10 year follow-up, reinforces the results seen from the DCCT-EDIC (for Type 1 diabetes). The Intervention Phase of the UKPDS revealed benefits for reduction of microvascular complications, while it was only at the end of the Post-Trial Monitoring Phase where significant improvements in both micro and macrovascular outcomes were seen. The other three Trials assessing the effect of glycaemic control on cardiovascular outcomes, although largely negative for CV benefit, give valuable insight towards appropriate patient characteristics for which aggressive glucose control can and should be instituted. Individualising glycaemic targets, which has been the approach that many clinicians have been practising, has received new impetus albeit with clearer details. Getting to glycaemic goal early in the course of T2DM and Doing to Safely (Avoiding hypoglycaemia)are the key ingredients to successful management. The legacy of the memory of initial good metabolic/glycaemic control is investment in good health with benefits of reductions in both micro and more importantly, macrovascular disease, years later. Multifactorial interventions that include blood pressure, lipid lowering in addition to glucose control in these individuals with the Metabolic Syndrome result in more immediate beneficial additive effects on cardiovascular outcomes.
Diabetes mellitus is the most common endocrine defect among children. Good diabetes management is important to give better health for both the children and the whole family. The goal of this study was to identify the level of mother involvement in children type·1 Diabetes Mellitus management, to identify factors related with mother involvement and to determine the relationships between mother
involvement and glycemic control. A cross·sectional study was carried out with 92 respondents selected by universal sampling from mothers who had diabetic children aged 5-15 years old and from medical visit appointment at University Kebangsaan Malaysia Medical Centre (UKMMC) and Putrajaya Hospital (HP1). Data was obtained through medical record and self reporting questionnaire. The study shown that 58.6% mothers had high involvement and 41.4% mothers had low involvement. Mothers' education level had a significant (p=0.0Z) relationship with a level of mother involvement. Most mothers gave high involvement in diet management (64.1%) and blood glucose monitoring (52. 7%), however most mothers gave low involvement in exercise management (63.0%) and insulin injection (60.9%). Mothers involvement in four management tasks were not statistically significant (p>0,05) with glycemic control. Mothers involvement in children diabetic management was high. There was high mother involvement in children's insulin injection and dietary intake and low mother involvement in children`s blood glucose monitoring and exercise, This study abo showed that there was no significant relationship between level of mother involvement and glycemic control.
Sepsis causes high mortality and morbidity. Static lactate concentration and early lactate clearance are cited to be a predictor for sepsis survival. This study examined the clinical utility of static lactate concentration and early lactate clearance within the first six hours of admission in Emergency Department (ED) to predict 28-day mortality rate in sepsis patients. Patients who presented with sepsis, severe sepsis or septic shock and admitted to ED of Universiti Kebangsaan Malaysia Medical Centre were recruited. Blood lactate concentrations were measured upon admission (H0), at 1st hour (H1) and 6th hour (H6), respectively. Either standard treatment of sepsis or early goal directed therapy was initiated according to sepsis severity. A follow-up report was conducted at 28 days via telephone call, e-mail or case notes. Patients were later classified into survivor and non-survivor as final outcome. Static lactate concentration appeared to be significantly higher for non-survivor as compared to the survival group at H0, H1 and H6 (p
Climate change is a product of human actions. The extreme events such as flash floods, droughts, heat waves, earthquakes, volcano eruptions and tsunamis seen in the world today are the result of indiscriminate human intrusion into the environment. Vulnerable countries and populations are the most affected by these climatic events. This places a burden on the resources of these countries. The Kyoto Protocol is a milestone in environmental management and the impetus created by it must be maintained by carrying out the much needed research into appropriate mitigating measures that will alleviate the climate
change impact globally. A paradigm shift is needed in addressing the associated risks on human health to assess socioeconomic determinants and the related impacts on disease burden. Some wealthy nations emphasize economic benefits and downplay sustainability goals, health and equality. However the rising cost of energy is beginning to influence their outlook towards this issue. The implications on economics, human health and wellbeing are implicit. In order to strike a balance between disadvantaged and privileged nations, many
international agencies are spearheading various research agenda to improve adaptation programmes on effects of changing climatic conditions on health. Malaysia too has such programmes initiated under its 5-year development plans.
Despite advances in the treatment regimen, the high incidence rate of breast cancer (BC) deaths is mostly caused by metastasis. Recently, the aberrant epigenetic modifications, which involve DNA methylation, histone modifications and microRNA (miRNA) regulations become attractive targets to treat metastatic breast cancer (MBC). In this review, the epigenetic alterations of DNA methylation, histone modifications and miRNA regulations in regulating MBC are discussed. The preclinical and clinical trials of epigenetic drugs such as the inhibitor of DNA methyltransferase (DNMTi) and the inhibitor of histone deacetylase (HDACi), as a single or combined regimen with other epigenetic drug or standard chemotherapy drug to treat MBCs are discussed. The combined regimen of epigenetic drugs or with standard chemotherapy drugs enhance the therapeutic effect against MBC. Evidences that epigenetic changes could have implications in diagnosis, prognosis and therapeutics for MBC are also presented. Several genes have been identified as potential epigenetic biomarkers for diagnosis and prognosis, as well as therapeutic targets for MBC. Endeavors in clinical trials of epigenetic drugs against MBC should be continued although limited success has been achieved. Future discovery of epigenetic drugs from natural resources would be an attractive natural treatment regimen for MBC. Further research is warranted in translating research into clinical practice with the ultimate goal of treating MBC by epigenetic therapy in the near future.
Music therapy is rarely available within the medical services in Malaysia. Hospitalized children experience a great deal of stress, anxiety, and pain due to unfamiliar environment, separation from the family, a variety of medical procedures and treatments, and the uncertainties of the illnesses. Music is often used to cope with both physical and psychological distress clinically because of its pervasiveness and familiarity. The purpose of this article is to elaborate the effectiveness of music therapy in addressing both physical and psychosocial needs of hospitalized children. The three case studies demonstrated how a variety of music therapy interventions are used to facilitate individualized goals and to improve the quality of life.
Oral cavity is a gateway to the entire body and protection of this gateway is a major goal in dentistry. Plaque biofilm is a major cause of majority of dental diseases and although various biomaterials have been applied for their cure, limitations pertaining to the material properties prevent achievement of desired outcomes. Nanoparticle applications have become useful tools for various dental applications in endodontics, periodontics, restorative dentistry, orthodontics and oral cancers. Off these, silver nanoparticles (AgNPs) have been used in medicine and dentistry due to its antimicrobial properties. AgNPs have been incorporated into biomaterials in order to prevent or reduce biofilm formation. Due to greater surface to volume ratio and small particle size, they possess excellent antimicrobial action without affecting the mechanical properties of the material. This unique property of AgNPs makes these materials as fillers of choice in different biomaterials whereby they play a vital role in improving the properties. This review aims to discuss the influence of addition of AgNPs to various biomaterials used in different dental applications.
The development of SPARK (Sport Play Active and Recreation for Kids) program is an effort to improve physical fitness activities among school children. In addition, the development of this program is planned and systematic activity that will help children express ideas freely, especially in the Physical Education or during Co-curriculum activities. In this study, the validity of the SPARK program is based on the Sidek & Jamaludin (2005) module. The SPARK (Sports Play Active and Recreation for Kids) content creation process begins with the goal and concludes with a draft union. In the initial stages of the content development, researchers determine the purpose and objective of this program. Besides that, Researchers determine the appropriate types of activities are applied to enhance the physical fitness activities for the students. Therefore, the development of the SPARK program is through two phases, namely program construction and validity of content. Therefore, the results of the expert assessment on SPARK (Sport Play Active and Recreation for Kids) program content have a high content legality value of .78. This value can be explained that the SPARK program (Sport Play Active and Recreation for Kids) is highly relevant to the learning and teaching process for Physical Education subjects, co-curricular activities and it is ideal use in this research. In conclusion, the program is expected to provide opportunities for children to undergo natural learning through cognitive social theories that contribute to the learning and teaching process for Physical and Health Education subjects to see the impact on the involvement of children's physical activity.
Globally, breast cancer is reported as a primary cause of death in women. More than 1.8 million new breast cancer cases are diagnosed every year. Because of the current limitations on clinical imaging, researchers are motivated to investigate complementary tools and alternatives to available techniques for detecting breast cancer in earlier stages. This article presents a review of concepts and electromagnetic techniques for microwave breast imaging. More specifically, this work reviews ultra-wideband (UWB) antenna sensors and their current applications in medical imaging, leading to breast imaging. We review the use of UWB sensor based microwave energy in various imaging applications for breast tumor related diseases, tumor detection, and breast tumor detection. In microwave imaging, the back-scattered signals radiating by sensors from a human body are analyzed for changes in the electrical properties of tissues. Tumorous cells exhibit higher dielectric constants because of their high water content. The goal of this article is to provide microwave researchers with in-depth information on electromagnetic techniques for microwave imaging sensors and describe recent developments in these techniques.
Palliative care for life limiting conditions usually starts at birth. In neonatal period, planning,
discussion and goal of care should focus towards improving the baby quality of life. It does not mean
palliative care in this age group mainly as end of life care. We illustrate a complex 30 weeks baby
who was born with genetic abnormality complicated with intracranial bleeding and acute myeloid
leukaemia. There were various ethical issues related to the approach of death and dying infant and
psychosocial challenges surrounding the case.
This goal of this study was to investigate the presence of Vibrio cholerae in street food,
namely satar and otak-otak, using Loop-Mediated Isothermal Amplification (LAMP),
multiplex Polymerase Chain Reaction (mPCR) and conventional plating on Thiosulphate
Citrate Bile-Salt Sucrose (TCBS) agar methods. A total of 78 satar and 35 otak-otak were
purchased from different districts of Terengganu (Besut, Setiu, Kuala Terengganu and
Kemaman). V. cholerae was found in satar with LAMP (10.3%), mPCR (10.3%) and
plating (0%). No V. cholerae was found in otak-otak using the three methods. This might
be due to V. cholerae able to survive in satar after grilling due to its thickness which may
contribute to undercooking. This study concluded that low presence of V. cholerae in satar
and otak-otak can be detected by molecular methods but not the conventional plating
method. LAMP assay is a useful tool for rapid detection of pathogens in food due to its
simplicity, highly sensitive and visual interpretation capability. Though the prevalence of
V. cholerae was low in the samples, proper handling of this food will help in reducing the
risk of acquiring infection from V. cholerae in contaminated samples.
