Neurodegenerative diseases are characterized by protein aggregates and inflammation as well as oxidative stress in the central nervous system (CNS). Multiple biological processes are linked to neurodegenerative diseases such as depletion or insufficient synthesis of neurotransmitters, oxidative stress, abnormal ubiquitination. Furthermore, damaging of blood brain barrier (BBB) in the CNS also leads to various CNS-related diseases. Even though synthetic drugs are used for the management of Alzheimer's disease, Parkinson's disease, autism, and many other chronic illnesses, they are not without side effects. The attentions of researchers have been inclined towards the phytochemicals, many of which have minimal side effects. Phytochemicals are promising therapeutic agents because many phytochemicals have anti-inflammatory, antioxidative as well as anticholinesterase activities. Various drugs of either synthetic or natural origin applied in the treatment of brain disorders need to cross the BBB before they can be used. This paper covers various researches related to phytochemicals used in the management of neurodegenerative disorders.

The merger of nanotechnology and combination chemotherapy has shown notable promise in the therapy of resistant tumors. The latest scientific attention encompasses the engagement of anticancer drugs in combination with small interfering (si)RNAs, such as VEGF, XLAP, PGP, MRP-1, BCL-2 and cMyc, to name but a few. siRNAs have shown immense promise to knockout drug resistance genes as well as to recover the sensitivity of resistant tumors to anticancer therapy. The nanotechnology approach could also protect siRNA against RNAse degradation as well as prevent off-target effects. In this article, we discuss the approaches that have been used to deliver of siRNA in combination with chemotherapeutic drugs to treat resistant tumors. We also discuss the stipulations that must be considered in formulating a nanotechnology-assisted siRNA-drug cancer therapy.

Fulltext Quality of life and its influencing factors among physically disabled teenagers in Kuala Lumpur, Malaysia

Shamsul, A.S., Mohd Rohaizat, H., Muholan, K., Noor Zaiha, H., Ang, W.C., Sei, F.S., et al.

Malaysian Journal of Public Health Medicine, 2013;13(2):11-19.
MyJurnal

A cross-sectional study was conducted from December 2009 till May 2010 to determine the quality of life and factors influencing it among physically disabled teenagers. Data were collected from 59 physically disabled teenagers using guided questionnaire Short Form 36 (SF-36) and General Health Questionnaires 12 (GHQ 12). Quality of life among physically disabled teenagers is low for most domains of SF-36 as compared to the general Malaysian population. There was significant difference in quality of life among different races (mental health domain) and among different educational level and type of disability (physical functioning domain). There was no significant association between general health domain and other variables. Higher satisfaction in house, school and recreational environment showed a better quality of life. Higher stress level had a lower quality of life. Lack of disabled friendly environment at home, school and recreational places probably contribute to their quality of life. Schools and public places should have more disabled friendly facilities to improve independency and accessibility. Better education and training will increase their independence and enhance self-confidence. More attention and support at this age is important for them to develop interpersonal skills and character for their future.

Mardiana Abdul Aziz, Effat Omar

Journal of Clinical and Health Sciences, 2020;5(2):66-74.
MyJurnal

Pyogenic granuloma-like Kaposi sarcoma (PGLKS) is an uncommon variant of Kaposi
sarcoma (KS), which mimics benign pyogenic granuloma both clinically and histologically. We
report a case of PGLKS of the toe occurring in a HIV-positive individual. It presented as a 2cm
skin swelling of 2 weeks’ duration which was clinically felt to be a pyogenic granuloma.
Histopathological examination revealed a polypoid atypical vascular lesion with overlying
peripheral epidermal collarette. Spindle cell proliferation typically seen in KS was also
identified, which was positive for human herpesvirus 8 (HHV8) by immunohistochemistry,
confirming the diagnosis of PGLKS. Upon review of the literature, our case is the 29th case of
PGLKS reported to date, and only the sixth in Asian population. Particular attention to
histomorphology, and demonstration of HHV8 in lesional tissue will aid accurate diagnosis of
this rare entity.

Quah Y, Mohd Ismail NI, Ooi JLS, Affendi YA, Abd Manan F, Teh LK, et al.

J Zhejiang Univ Sci B, 2019 1 8;20(1):59-70.
PMID: 30614230 DOI: 10.1631/jzus.B1700586

Globally, peptide-based anticancer therapies have drawn much attention. Marine organisms are a reservoir of anticancer peptides that await discovery. In this study, we aimed to identify cytotoxic oligopeptides from Sarcophyton glaucum. Peptides were purified from among the S. glaucum hydrolysates produced by alcalase, chymotrypsin, papain, and trypsin, guided by a methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay on the human cervical cancer (HeLa) cell line for cytotoxicity evaluation. Purification techniques adopted were membrane ultrafiltration, gel filtration chromatography, solid phase extraction (SPE), and reversed-phase high-performance liquid chromatography (RP-HPLC). Purified peptides were identified by de novo peptide sequencing. From papain hydrolysate, three peptide sequences were identified: AGAPGG, AERQ, and RDTQ (428.45, 502.53, and 518.53 Da, respectively). Peptides synthesized from these sequences exhibited cytotoxicity on HeLa cells with median effect concentration (EC50) values of 8.6, 4.9, and 5.6 mmol/L, respectively, up to 5.8-fold stronger than the anticancer drug 5-fluorouracil. When tested at their respective EC50, AGAPGG, AERQ, and RDTQ showed only 16%, 25%, and 11% cytotoxicity to non-cancerous Hek293 cells, respectively. In conclusion, AERQ, AGAPGG, and RDTQ are promising candidates for future development as peptide-based anticancer drugs.

The last decade has witnessed dramatic changes in global food consumption patterns mainly because of population growth and economic development. Food substitutions for healthier eating, such as swapping regular servings of meat for protein-rich crops, is an emerging diet trend that may shape the future of food systems and the environment worldwide. To meet the erratic consumer demand in a rapidly changing world where resources become increasingly scarce due largely to anthropogenic activity, the need to develop crops that benefit both human health and the environment has become urgent. Legumes are often considered to be affordable plant-based sources of dietary proteins. Growing legumes provides significant benefits to cropping systems and the environment because of their natural ability to perform symbiotic nitrogen fixation, which enhances both soil fertility and water-use efficiency. In recent years, the focus in legume research has seen a transition from merely improving economically important species such as soybeans to increasingly turning attention to some promising underutilized species whose genetic resources hold the potential to address global challenges such as food security and climate change. Pulse crops have gained in popularity as an affordable source of food or feed; in fact, the United Nations designated 2016 as the International Year of Pulses, proclaiming their critical role in enhancing global food security. Given that many studies have been conducted on numerous underutilized pulse crops across the world, we provide a systematic review of the related literature to identify gaps and opportunities in pulse crop genetics research. We then discuss plausible strategies for developing and using pulse crops to strengthen food and nutrition security in the face of climate and anthropogenic changes.

Introduction: Interest in mindfulness and its enhancements have quietly exploded in recent years, bringing with it the need for validated instruments to assess mindfulness in the Malaysian population. The study aims to assess the reliability, factor structure and validity of the Malay version of The Mindful Attention Awareness Scale (MMAAS) in a group of nursing students. Methods: The MMAAS was ‘forward-backward’ translated from English to Malay. Two hundred and sixty six nursing students answered the MMAAS. At the same time, they responded to the General Health Questionnaire (GHQ) and Rosenberg Self-Esteem Scale (RSES). We performed Exploratory Factor Analysis (EFA) with varimaxrotation to examine the factor structure of the MMAAS. Associations of retained factors were estimated by Spearman correlation coefficients. Results: Internal consistency reliability of MMAAS was good (Cronbach’s α = 0.851) and showed temporal stability in a 3-week period. Exploratory Factor Analysis (EFA) suggested three factors labelled as “Attention related to generaldomain”, “Attention related to the physicaldomain” and “Attention related to psychological domain”. These factors explained 52.09% of the variance. The Malay MAAS and the English version was highly correlated (r=0.82, p

Chew BH, Shariff-Ghazali S, Fernandez A

World J Diabetes, 2014 Dec 15;5(6):796-808.
PMID: 25512782 DOI: 10.4239/wjd.v5.i6.796

Patients with diabetes mellitus (DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient's adherence to the effective therapies, there would be persistent sub-optimal control of diseases, increase diabetes-related complications, causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient's psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation, self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors, coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relation to DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

Fulltext Psidium guajava fruit peel extract reduces oxidative stress of pancreas in streptozotocin-induced diabetic rats

Siti Balkis Budin, Hawa Ismail, Pek LC

Sains Malaysiana, 2013;42:707-713.

Abundant natural products with medicinal properties have been used as food and traditional medicine for diabetes mellitus all over the world. Psidium guajava fruit from the family of Myrtaceae has gained attention for its antioxidant potential. This study was conducted to determine the effects of P. guajava fruit peel aqueous extract on oxidative stress of pancreas in streptozotocin-induced (45 mg/kg) diabetic rats. Diabetic rats were administered with 400 mg/kg of aqueous extract of P. guajava fruit peel daily for 28 days duration. The results showed that diabetic rats supplemented with P. guajava extract did not cause significant difference in blood glucose level (p>0.05) as compared with diabetic rats alone. For oxidative stress evaluation, malondialdehyde (MDA) and protein carbonyl level were significantly lower and the activity of superoxide dismutase (SOD) and glutathione (GSH) level were significantly higher (p<0.05) in P. guajava supplemented rats compared with non-supplemented diabetic rats. However, histological observation showed that supplementation of P. guajava extract did not give protective effects towards alterations in pancreas histology in diabetic rats. The findings suggested that aqueous extract of P. guajava fruit peel supplementation has the ability to reduce oxidative stress in pancreas of diabetic rats and may play a role in reducing the development of diabetic complications.

PMID: 26703542 DOI: 10.3390/molecules201219884

The aim of this review was to analyze/investigate the synthesis, properties, and applications of polyvinyl alcohol-halloysite nanotubes (PVA-HNT), and their nanocomposites. Different polymers with versatile properties are attractive because of their introduction and potential uses in many fields. Synthetic polymers, such as PVA, natural polymers like alginate, starch, chitosan, or any material with these components have prominent status as important and degradable materials with biocompatibility properties. These materials have been developed in the 1980s and are remarkable because of their recyclability and consideration of the natural continuation of their physical and chemical properties. The fabrication of PVA-HNT nanocomposites can be a potential way to address some of PVA's limitations. Such nanocomposites have excellent mechanical properties and thermal stability. PVA-HNT nanocomposites have been reported earlier, but without proper HNT individualization and PVA modifications. The properties of PVA-HNT for medicinal and biomedical use are attracting an increasing amount of attention for medical applications, such as wound dressings, drug delivery, targeted-tissue transportation systems, and soft biomaterial implants. The demand for alternative polymeric medical devices has also increased substantially around the world. This paper reviews individualized HNT addition along with crosslinking of PVA for various biomedical applications that have been previously reported in literature, thereby showing the attainability, modification of characteristics, and goals underlying the blending process with PVA.

Introduction. In light of the important role of health-promoting expenditure in health, the objective of this study was to investigate the socio-demographic determinants of health-promoting expenditure such as purchase of medical equipment and services, food supplements and health education services and products among Malaysian adults.
Methods Third National Health and Morbidity Survey (NHMS III) consisting of 28771 observations was used for analysis. It was the latest nationally representative cross-sectional population-based survey conducted by the Ministry of Health Malaysia from April 2006 to January 2007. A censored regression model
(Tobit) was applied to examine the factors affecting health-promoting expenditure.
Results The results showed that age, income, gender, ethnicity, education, marital status, employment status and location of residence were able to affect health promoting expenditure. In particular, individuals who were younger, poor, males, Indian/others, less educated, unmarried, unemployed and residing in rural areas tended to spend less money on health promotion compared to others.
Conclusions This study reached a conclusion that socio-demographic factors were significantly associated with individual’s preferences for health promotion. Therefore, the government should devote its attention to these factors when
formulating nationwide health policies.

An accuracy in the hydrological modelling will be affected when having limited data sources especially at ungauged areas. Due to this matter, it will not receiving any significant attention especially on the potential hydrologic extremes. Thus, the objective was to analyse the accuracy of the long-term projected rainfall at ungauged rainfall station using integrated Statistical Downscaling Model and Geographic Information System (SDSM-GIS) model. The SDSM was used as a climate agent to predict the changes of the climate trend in Δ2030s by gauged and ungauged stations. There were five predictors set have been selected to form the local climate at the region which provided by NCEP (validated) and CanESM2-RCP4.5 (projected). According to the statistical analyses, the SDSM was controlled to produce reliable validated results with lesser %MAE (<23%) and higher R. The projected rainfall was suspected to decrease 14% in Δ2030s. All the RCPs agreed the long term rainfall pattern was consistent to the historical with lower annual rainfall intensity. The RCP8.5 shows the least rainfall changes. These findings then used to compare the accuracy of monthly rainfall at control station (Stn 2). The GIS-Kriging method being as an interpolation agent was successfully to produce similar rainfall trend with the control station. The accuracy was estimated to reach 84%. Comparing between ungauged and gauged stations, the small %MAE in the projected monthly results between gauged and ungauged stations as a proved the integrated SDSM-GIS model can producing a reliable long-term rainfall generation at ungauged station.

Introduction: Appropriate professional conduct of clinical teacher is vital in their medicine practice. In UKM medical centre Malaysia, personal and professional development (PPD) of future medical professionals is greatly emphasized. The objective of this study was to determine the medical students' perception about the professional conduct of their clinical teachers at UKM medical centre. Methods: It was an online questionnaire survey conducted among the clinical students enquiring about the professional conduct of their clinical teachers. There were five statements and one open ended question which described students' preference about PPD teaching- learning method, expectation on PPD session, need of teachers training and experience about the excellent and inappropriate professional conduct of clinical teachers. The open ended question described what students had observed regarding the 'doctor-patient relationship' medical ethics and 'student-teacher relationship. A total of 77 questionnaires were returned after complete evaluation. The data were compiled and analysed using SPSS version 20 and the answers to the open ended questions were transcribed. Result: Role modelling was the preferred teaching-learning method for PPD as stated by 38% respondents; subsequent preferred methods were small group (30%), role play (24%), large group (7%) and reflective writing (1%). Majority (67.5%) respondents indicated that professional conduct of their clinical teachers was frequent enough as they had expected while 29.9% claimed that professional conduct was infrequently emphasized. Excellent professional conduct of clinical teachers was witnessed by 73% respondents while 27% indicated that they had never seen excellent conduct. When asked about inappropriate professional behaviours by clinical teachers, 53% indicated to have witnessed. Qualitative data also revealed both positive and negative experiences as reflected in open comments. According to 70% respondents clinical teachers required training to apply PPD in their daily practices. Conclusion: Professional conduct of clinical teachers as perceived by the students was excellent and frequents enough with experience of inappropriate behaviour too. Role modeling was the preferred teaching method while attention needed on reflective assignment. Educators must emphasize on role modelling in their daily practices and curriculum planners should give due importance on training needs of clinical teachers to apply PPD in their daily practices.
