An anomalous pattern of superficial branch of radial nerve - a Cadaveric case report

In the present case study, there is an anomalous pattern of superficial branch of radial nerve (SBRN) that can be recognized as an anatomical variant of the left upper limb of a 60 years old donated embalmed male cadaver in the Department of Human Anatomy, Universiti Putra Malaysia, in which the superficial branch of radial nerve supplies the extensor carpi radialis longus and extensor carpi radialis brevis muscle. The superficial branch of radial nerve gave off branch to supply the proximal fusion part of extensor carpi radialis longus and extensor carpi radialis brevis muscles immediately after bifurcation of the radial nerve into the superficial branch of radial nerve and deep branch of radial nerve. This variation is very important to the surgeon as the presence of the variant will make them more careful in dealing with nerve entrapment surgery, reconstructive surgery and in the pain management services, the variation giving indications for treatment

In vitro antiatherothrombotic effects of extracts from Berberis vulgaris L., Teucrium polium L., and Orthosiphon stamineus benth

Coronary artery disease is the leading cause of mortality and morbidity worldwide. The pathogenesis is mainly due to atherosclerosis, plaque rupture, and platelet thrombus formation. The main risk factors for coronary artery disease include obesity, hypercholesterolemia, smoking, diabetes, and high blood pressure. As a part of disease management, treatment options using anticoagulant and antiplatelet drugs can be applied with addition to lipid-lowering medication. However, medicinal plants comprising antiatherothrombotic effects can be used as options to combat the disease rather than drug therapies with lesser adverse effects. Therefore, the haematological effect of Berberis vulgaris L., Teucrium polium L., and Orthosiphon stamineus Benth extracts was studied using in vitro model to prevent and to treat coronary atherothrombotic disease. The aqueous, methanol, and polysaccharide extracts of B. vulgaris, T. polium, and O. stamineus, respectively, were studied for their anticoagulant and antiplatelet effect on human whole blood. Extracts were subjected to the prothrombin time (PT) and activated partial thromboplastin time (APTT) test for anticoagulant activity. The antiplatelet activity was investigated using an electrical impedance method. B. vulgaris aqueous extract (BVAE), B. vulgaris polysaccharide extract (BVPE), T. polium aqueous extract (TPAE), and T. polium polysaccharide extract (TPPE) significantly prolonged the coagulation time in a concentration-dependent manner (p<0.05). The administration of BVAE demonstrated the most effective antiplatelet activity against platelet aggregation caused by arachidonic acid (AA) and collagen. These antiplatelet activities may correspond to the presence of higher total phenolic compound, which thus inhibit the platelet aggregation activity. In conclusion, these findings provide strong evidence on the antiatherothrombotic effect of BVAE and TPAE

Facial muscles and its modiolus: a review of embryology, comparative anatomy, morphology and applied anatomy

The modiolus of the face manifests the interesting landmark for facial muscles attachment. The strong connective tissue fibres play an important role in the clinical setting, especially in the aesthetic and dental surgeries. In the fourth week of intrauterine life, the development of the modiolus evolves in accordance with the growth of muscles of facial expression. Microscopically, a white, tendinous structure with the thick irregular collagenous connective tissue of collagen fibres predominance appeared to be the modiolus. Modiolus is morphologically a fibromuscular muscle situated on the lateral border of the mouth. The formation of the nasolabial fold is important and a well-developed modiolus provide a toned face. Several works of literature forementioned the number of facial muscles attached to the modiolus but no definitive similarity are identified. This review summarizes the updated morphological features and applied anatomy of the facial modiolus with its muscle attachment

Chemicals used for the induction of Alzheimers disease-like cognitive dysfunctions in rodents

Alzheimer's disease (AD) is the most frequent and multifactorial form of dementia, characterised by multiple cognitive impairments and personality changes. Different methods including chemicals have been used to induce AD-like symptoms in rodent in order to screen many therapeutic drugs for a variety of cognitive dysfunctions. Articles from reliable databases such as Google Scholar, Science Direct, PubMed, Scopus, and Ovid were searched and retrieved with the following descriptors: 'Alzheimer's Disease', Cognitive impairments', Neurotoxins that induce AD', Alzheimerogenic chemicals', excitotoxins', Amyloid beta', neurofibrillary tangles. A number of chemicals have been studied to develop an animal model of AD on the basis of their mechanism of action for cognitive dysfunctions. Some of such chemicals are Heavy metals, Scopolamine, Ethanol, Colchicine, Streptozotocin, Lipopolysaccharide, and Okadaic acid among others, with a view to understanding the pathogenesis of this devastating disease. The purpose of this review is to put forward some AD pathophysiology including AD causative theories and also highlight some Alzheimerogenic chemicals for the purpose of enriching our existing knowledge. It is worth mentioning that not all the biochemical, histopathological, cognitive and behavioural abnormalities can be recapitulated. Nonetheless, experimental models of AD produced by chemicals offer insights to unravelling the pathogenesis of the disease

Association between the level of knowledge, awareness and attitude on post-COVID-19 syndrome amongst medical students in four Malaysian universities

Introduction: COVID-19 is a respiratory illness that is caused by a coronavirus. Infected people will have a chance to develop post-COVID-19 syndrome. The aim of this study is to identify the association of gender, marital status, age and university on knowledge, awareness and attitude of post-COVID-19 syndrome among medical students in four universities in Malaysia. Methods: A cross-sectional study was conducted from October 2021 to July 2022 at four universities in Malaysia which are Universiti Putra Malaysia (UPM), Universiti Islam Antarabangsa Malaysia (UIAM), Universiti Sains Malaysia (USM) and Universiti Sains Islam Malaysia (USIM). A self-administered questionnaire was administered to 355 respondents consisted of four sections, assessing socio-demographic data and knowledge, awareness and attitudes of post-COVID-19 syndrome. Results: 54.4% of the respondents had high knowledge, 53.8% had high awareness, and 55.21% had a high attitude towards post-COVID-19 syndrome. In this study, there is a significant association between knowledge on post-COVID-19 syndrome and the age among respondents. Knowledge and awareness, knowledge, and attitude as well as awareness and attitude on post-COVID-19 syndrome was also found to have significant association among respondents. Conclusion: The older age of the respondents have good knowledge towards post-COVID-19 syndrome

A Review of Multimedia Usage in Embryology Education

Embryology, which is a part of anatomy curriculum, is well known to be most difficult to teach. Applied embryology is important in medical practice especially in obstetrics and gynecology. To support teaching embryology, a few multimedia methods have been introduced for the past twenty years, such as animations, two dimensional illustrations, three-dimensional illustrations, movies, and video. Innovative anatomy teaching and learning technology, particularly in the embryology syllabus, dramatically boosts students’ understanding and interest while also indirectly simplifies anatomists’ job. Students are excited to be able to visualize the embryo changes at any gestational age from fertilization to fetus development. Students’ motivation is increased, and their comprehension and memorization are improved. In this review, we elaborate on the details of multimedia methods used for embryology teaching and learning as an alternative to traditional lectures and tutorials. The variety of approaches aids in reducing boredom and maintaining high levels of concentration. As a result, the multimedia usage is useful for long-term memorization

Face mask usage during Covid-19 pandemic: prevalence and factors associated in Malaysian Medical School

Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a newly discovered coronavirus strain. Anxiety, anticipation, and lack of knowledge in the previous experience on severe acute respiratory syndrome (SARS) and influenza A virus subtype H1N1 (H1N1) pandemic have a substantial impact on significant public health behaviours including wearing face mask in public spaces. We investigate the prevalence of face mask usage and its associated factors during COVID19 amongst students and staff of the Faculty of Medicine and Health Sciences (FMHS), Universiti Putra Malaysia (UPM). Using a cross-sectional study, 220 respondents participated in an electronic version of a self-administered questionnaire. Analyses were performed using the Chi-square test, IBM SPSS Statistics 25, with statistical significance at p<0.05. Out of the 220 respondents, 197 (89.5%) reported that they wore face masks all the time. Most of the respondents (90.3%) had a high level of precautionary measures against COVID-19, 89.6% selected the internet as their source of information and 90.9% had a good attitude level towards measures against COVID-19. There were significant associations between hygienic practices (p=0.001), source of information (internet) (p=0.025), and attitude towards COVID-19 (p=0.001) with face mask usage. This study demonstrated a high prevalence (89.5%) of face mask usage during the COVID-19 outbreak

Association between level of knowledge gained, confidence, motivation and flexibility on types of learning for bedside teaching among clinical students in four Malaysian medical schools during Covid-19 pandemic

Introduction: With the arise of the COVID-19 pandemic, higher institutions are forced to change the method of delivery for bedside teaching sessions from face-to-face to online learning. However, online learning was found not effective in delivering practical knowledge and skills to students. Hence, the objective of this study was to determine the association between level of knowledge gained, confidence, motivation and flexibility on types of learning for bedside teaching sessions among clinical students in four Malaysian medical schools during COVID-19 pandemic. Methods: A cross-sectional study involving medical students from Universiti Putra Malaysia (UPM), Universiti Sains Islam Malaysia (USIM), Universiti Islam Antarabangsa (UIA) and Universiti Sains Malaysia (USM) were conducted from 1st March 2021 until 6th June 2021. An online questionnaire was distributed and it consisted of 5 sections which cover sociodemographic information, level of knowledge gained, confidence, motivation, and flexibility from bedside teaching session. The data was analysed by using SPSS software program. Results: There is a significant association between the level of knowledge gained, level of confidence, level of motivation and level of flexibility with the type of learning (online or face-to-face) during bedside teaching sessions. Results revealed that students gained a higher level of knowledge (84.9%), higher level of confidence in physical examination (93.3%), higher motivation (82.2%) and higher flexibility (64.1%) during face-to-face bedside teaching sessions compared to online learning. Conclusion: Most of the medical students in four Malaysian medical schools prefer face-to-face learning compared to online learning for bedside teaching session
