Background and Aim: Obesity exhibits wide variety of electrocardiogram (ECG) abnormalities in adults. Previous researches have found different results since they tested mostly on children, adolescents, and middle aged persons. However, there’s no clear evidence of the association between obesity and ECG variables, especially in young adults. Hence, the aim of this research is to compare ECG parameters (PR interval, QRS interval, corrected QT, axis and height of P and R wave) of obese with normal BMI young adults.Materials and method: A cross-sectional observational study was done on 38 students of a private university in Shah Alam. They were aged between 20 to 30 years, involving normal and obese persons. Anthropometric data, arterial blood pressure and standard 12-lead ECGs were collected for every participant. Independent-sample t-tests and non-parametric Mann-Whitney test were conducted to compare data of normal persons and obese persons. Pearson correlation was done to correlate ECG parameters with BMI, Weight and systolic arterial blood pressure.Results: Heart rate, PR interval, QRS interval and QT interval of obese person were not significantly different from normal. Height of R wave in obese person is more than that of normal person (P<0.05). However, there was no correlation between BMI, Weight, systolic blood pressure and ECG parameters that could be found.Conclusion: Thus, ECG wave and intervals except height of the R wave of obese young adults are not significantly different from those of the normal BMI. Finding of higher R wave in obese groups indicates ventricle wall of obese young adults are thicker than that of the young adults with normal BMI and it is not related to the effect of systolic arterial blood pressure, BMI and even weight of the person

Bullying tends to happen most often in and around the school, specifically in the areas where adult supervision is little or none at all. Campaigns on bully awareness is proven unsuccessful considering the situation has been going on and keep happening. This also due to the lack of firm and indecisive action against the bully. This research will focus on encouraging the victims to participate and learn how to defend themselves against bully. By learning martial arts, the victim will be able to defend themselves independently and stop putting hopes for others to do so in their rights. The objective of this marketing campaign is to encourage the bully victims to learn martial arts in order to defend themselves. The promotional marketing items that will be distributed along with the campaign shall explain the benefits of learning martial arts and where they can sign up for the courses. The concept and design theme for the promotional items will be made suitable and appealing for the target audiences. An attractive publishing is proved effective as a promotional items since it has the ability to persuade and pique the interest of the victims in learning how to defend themselves against bully. This, in hope will slowly but surely reduce the frequency of bully.

Nanotechnology is one of the most developing areas which involve utilization of materials with structural dimension in of 1-100 nm. This technology opened a pathway for the synthesis of silver nanoparticle by various physical and chemical methods. The biosynthesis method from plant extracts are considered as alternative as it is relatively simple, nontoxic, and environmentally friendly methods. The objective was to synthesize and characterize silver nanoparticle via ultraviolet visible spectroscopy of silver nanoparticles from three piper species which are Piper nigrum, Piper sarmentosum and Piper betel. Silver nanoparticles were prepared by the reaction of 1 mM of 90 ml silver nitrate and 10 ml methanolic leaf extract of each type of plant that act as reductant and stabilizer. The synthesized nanoparticle was characterized by color changes from green into dark brown with increasing intensity of the color from 10 minutes until 48 hour indicating the completion of silver nanoparticle formation at 48 hour. A UV–Vis spectrum of the methanolic medium containing silver nanoparticles demonstrated a peak at 413 nm, 417 nm and 420 nm for Piper nigrum, Piper sarmentosum and Piper betel respectively that corresponds to the plasmon absorbance of silver nanoparticles. The maximum percentage increase in the rate of absorbance was found specifically at 24 hour in all the three leaf. In conclusion piper species is a source for synthesizing silver nanoparticles and Piper nigrum being an excellent source for the synthesis due to the narrow, sharp peak and showing maximum percentage increase at 24 hour among all the three plants. This study exhibited the potential of three methanolic extract of piper species for the green synthesis of silver nanoparticles.

Bloodstains as physical and biological evidence encountered in number of crimes will provide vital information to define a type of crime and link a suspect to the scene of a crime. This research will enlighten the identification of bloodstain on different types of fabrics which were washed with detergents prior to applying Kastle-Meyer (KM) tests. All six types of fabric were stained with blood and soaked in commonly used detergents in Malaysia for a various soaking time. It is found that Dynamo detergent shows the highest percentage in removing the bloodstain from all those six fabrics. Besides, soaking time interval of 60 minutes in all detergent showed the maximum removal of bloodstains compared to 20 minutes which has minimal ability to remove bloodstains. Among all the fabrics, cotton showed the maximum percentage of bloodstain retention after washing with all the detergent. The finding of the study would help forensic investigator to trace invisible bloodstain such as in washed clothing in order to solve the crimes.

Background and Aims: In every disease, there will be the triggers on the occurrences. One of them is the oxidative stress, an imbalance between free radicals such as reactive oxygen species (ROS) and the antioxidants. The human body manages free radicals through neutralization by the antioxidative defense mechanism, however, when excessive free radicals being produced, it will become less effective. Over 40 years of age, oxidative stress become prominent and may associated with many diseases such as neural disorders and cardiovascular diseases. Oxidative stress can cause damage to lipids, known as lipid peroxidation, producing malondialdehyde (MDA), a marker to detect the degree of oxidative stress. Availability of oxygen (O2) is the main factor of the ROS formation, which could be indicated by haemoglobin (Hb) concentration. Thus, this research is conducted to find out the correlation between Hb concentration and MDA level in healthy middle age adults.Methods: A correlation study was conducted in a private University, Shah Alam from January 2018 until March 2018. Total 16 participants, who are MSU staffs, age between 45 and 65, with no known diseases, are selected after the consents are gained. Pearson correlation was used for statistical analysis of the data.Results: It is found that there is a strong correlation between Hb concentration and MDA level (r: .756, p <0.001). This means that MDA production is significantly increased when the Hb concentration is increased.Conclusion: The MDA level is strongly correlate with the Hb concentration in the middle age apparently healthy adults. It can be postulated that MDA production correlates with oxygen availability at the intracellular respiration in normal middle aged person
背景和目的:每一种疾病的发生都有其触发因素。其中之一是氧化应激，即自由基如活性氧(ROS)和抗氧化剂之间的不平衡。人体通过抗氧化防御机制来中和自由基，但当自由基产生过多时，其作用就会减弱。超过40岁，氧化应激变得突出，并可能与许多疾病有关，如神经障碍和心血管疾病。氧化应激可引起脂质损伤，即脂质过氧化，产生丙二醛(MDA)，这是检测氧化应激程度的标志。氧的可用性(O2)是ROS形成的主要因素，这可以通过血红蛋白(Hb)浓度来指示。因此，本研究旨在了解健康中年人Hb浓度与MDA水平的相关性。方法:2018年1月至2018年3月在沙阿南一所私立大学进行相关研究。在征得同意后，选择16名参与者，年龄在45 - 65岁之间，无已知疾病。采用Pearson相关法对数据进行统计分析。结果:Hb浓度与MDA水平有较强的相关性(r: 0.756, p <0.001)。这意味着当Hb浓度增加时，MDA的产生显著增加。结论:明显健康的中年成人血清丙二醛水平与Hb浓度密切相关。可以推测，正常中年人细胞内呼吸时丙二醛的产生与氧的可利用性有关

Idiopathic scoliosis is a spinal deformity which affects patient’s self-esteem, self-image and quality of life. Surgery is offered when the curve is more than 45 degree based on its progression. The objective of this study is to determine the pre and post-surgical self-esteem, self-image and quality of life in idiopathic scoliosis patients. A cross sectional study was conducted by using Scoliosis Research Society-30 (SRS-30) self-administered patient questionnaire. There are 115 patients were recruited in this study where 35 (30.43%) male and 80 (69.6%) female patients. Age of patient ranged from 10 to 49 years old with mean age of 24.65 ± 7.704. There were 42 (36.52%) Malay patients, 40 (34.78%) Chinese patients, 25 (21.73%) Indian patients and 8 (6.96%) from other races. Results shows that self-esteem and self-image is significantly higher (r = 0.216, p=0.021) after surgery compared to before surgery. As for quality of life, physical function did not significantly change after surgery but quality of life based on psychological function and social wellbeing is significantly higher after surgery. Positive association were found between satisfaction of treatment with self-image (r = 0.713, p=0.00) and self-image with self-esteem (r = 0.216, p=0.021) and negative association found between satisfaction of treatment with self-esteem (r = - 0.210, p=0.024). In conclusion patients with idiopathic scoliosis report lower self-esteem and self-image before surgical treatment and significantly improves after surgical correction and patients are generally satisfied with their life as well as the outcome of surgical treatment.
