    PMID: 23730953 DOI: 10.1111/resp.12137
    BACKGROUND AND OBJECTIVE: The Asthma Insight and Management (AIM) survey was conducted in North America, Europe, the Asia-Pacific region and Latin America to characterize patients' insights, attitudes and perceptions about their asthma and its treatment. We report findings from the Asia-Pacific survey.
    METHODS: Asthma patients (≥12 years) from Australia, China, Hong Kong, India, Malaysia, Singapore, South Korea, Taiwan and Thailand were surveyed. Patients answered 53 questions exploring general health, diagnosis/history, symptoms, exacerbations, patient burden, disease management, medications/treatments and patient's attitudes. The Global Initiative for Asthma guidelines were used to assess asthma control. The survey was conducted by random digit telephone dialling (Australia, China and Hong Kong) or by random face-to-face interviews (India, Malaysia, Singapore, South Korea, Taiwan and Thailand).
    RESULTS: There were 80 761 households screened. Data from 3630 patients were collected. Wide disparity existed between objective measures of control and patient perception. Reported exacerbations during the previous year ranged from 19% (Hong Kong) to 67% (India). Reported unscheduled urgent/emergency visits to a doctor's office/hospital/clinic in the previous year ranged from 15% (Hong Kong) to 46% (Taiwan). Patients who reported having controlled asthma in the previous month ranged from 27% (South Korea) to 84% (Taiwan). Substantial functional and emotional limitations due to asthma were identified by 13% (South Korea) to 78% (India) of patients.
    CONCLUSIONS: Asthma has a profound impact on patients' well-being despite the availability of effective treatments and evidence-based management guidelines. Substantial differences across the surveyed countries exist, suggesting unmet, country-specific cultural and educational needs. A large proportion of asthma patients overestimate their level of control.

  2. Fulltext The potential of intra-articular injection of chondrogenic-induced bone marrow stem cells to retard the progression of osteoarthritis in a sheep model
    Al Faqeh H, Nor Hamdan BM, Chen HC, Aminuddin BS, Ruszymah BH
    Exp Gerontol, 2012 Jun;47(6):458-64.
    PMID: 22759409 DOI: 10.1016/j.exger.2012.03.018
    In recent years, the use of bone marrow mesenchymal stem cell (BMSC) implantation has provided an alternative treatment for osteoarthritis. The objective of this study is to determine whether or not an intra-articular injection of a single dose of autologous chondrogenic induced BMSC could retard the progressive destruction of cartilage in a surgically induced osteoarthritis in sheep. Sheep BMSCs were isolated and divided into two groups. One group was cultured in chondrogenic media containing (Ham's F12:DMEM, 1:1) FD+1% FBS+5 ng/ml TGFβ3+50 ng/ml IGF-1 (CM), and the other group was cultured in the basal media, FD+10% FBS (BM). The procedure for surgically induced osteoarthritis was performed on the donor sheep 6 weeks prior to intra-articular injection into the knee joint of a single dose of BMSC from either group, suspended in 5 ml FD at density of 2 million cells/ml. The control groups were injected with basal media, without cells. Six weeks after injection, gross evidence of retardation of cartilage destruction was seen in the osteoarthritic knee joints treated with CM as well as BM. No significant ICRS (International Cartilage Repair Society) scoring was detected between the two groups with cells. However macroscopically, meniscus repair was observed in the knee joint treated with CM. Severe osteoarthritis and meniscal injury was observed in the control group. Interestingly, histologically the CM group demonstrated good cartilage histoarchitecture, thickness and quality, comparable to normal knee joint cartilage. As a conclusion, intra-articular injection of a single dose of BMSC either chondrogenically induced or not, could retard the progression of osteoarthritis (OA) in a sheep model, but the induced cells indicated better results especially in meniscus regeneration.

    Shahar MA, Hussein H, Sidi H, Shah SA, Mohamed Said MS
    Int J Rheum Dis, 2012 Oct;15(5):468-77.
    PMID: 23083037 DOI: 10.1111/j.1756-185X.2012.01753.x
    AIM: To determine the prevalence of sexual dysfunction (FSD) among women with rheumatoid arthritis attending the Rheumatology Clinic in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and Hospital Putrajaya, Malaysia, and to determine its associations with potential clinical and disease activity factors.
    METHOD: This was a cross-sectional study involving women with rheumatoid arthritis between the ages of 20 and 60 years. A validated Malay Version Female Sexual Function Index (MVFSFI) was administered to diagnose FSD. Sociodemographic and disease activity profiles were obtained and those who had and did not have FSD were compared.
    RESULTS: Among 63 respondents, 51 patients were included in the analysis for FSD. The prevalence of FSD in women with rheumatoid arthritis attending UKMMC and Hospital Putrajaya Rheumatology Clinic was 29.4%. Erythrocyte sedimentation rate (ESR) and Disease Activity Score in 28 joints (DAS28-ESR) correlates with MVFSFI score with r=-0.364 (P=0.009) and r=-0.268 (P=0.057), respectively. Sociodemographic factors that correlate with MVFSFI score were: patient's age (r=0.520, P<0.001); duration of marriage (r=-0.355, P=0.001); husband's age (r=-0.460, P=0.001); age of oldest child (r=-0.449, P=0.001); and age of youngest child (r=-0.627, P<0.001).
    CONCLUSION: We found in this study that the prevalence of FSD in rheumatoid arthritis in our centers was 29.4%. Age and family dynamics appear to be more important predictors compared to disease activity.

  4. Human mesenchymal stromal cells could deliver erythropoietin and migrate to the basal layer of hair shaft when subcutaneously implanted in a murine model
    Mok PL, Cheong SK, Leong CF, Chua KH, Ainoon O
    Tissue Cell, 2012 Aug;44(4):249-56.
    PMID: 22560724 DOI: 10.1016/j.tice.2012.04.002
    Mesenchymal stromal cells (MSC) are an attractive cell-targeting vehicle for gene delivery. MIDGE (an acronym for Minimalistic, Immunologically Defined Gene Expression) construct is relatively safer than the viral or plasmid expression system as the detrimental eukaryotic and prokaryotic gene and sequences have been eliminated. The objective of this study was to test the ability of the human MSC (hMSC) to deliver the erythropoietin (EPO) gene in a nude mice model following nucleofection using a MIDGE construct. hMSC nucleofected with MIDGE encoding the EPO gene was injected subcutaneously in Matrigel at the dorsal flank of nude mice. Subcutaneous implantation of nucleofected hMSC resulted in increased hemoglobin level with presence of human EPO in the peripheral blood of the injected nude mice in the first two weeks post-implantation compared with the control groups. The basal layer of the hair shaft in the dermal layer was found to be significantly positive for immunohistochemical staining of a human EPO antibody. However, only a few basal layers of the hair shaft were found to be positively stained for CD105. In conclusion, hMSC harboring MIDGE-EPO could deliver and transiently express the EPO gene in the nude mice model. These cells could be localized to the hair follicle and secreted EPO protein might have possible role in hair regeneration.

  5. Effect of extracts from Phyllanthus watsonii Airy Shaw on cell apoptosis in cultured human breast cancer MCF-7 cells
    Ramasamy S, Abdul Wahab N, Zainal Abidin N, Manickam S
    Exp. Toxicol. Pathol., 2013 Mar;65(3):341-9.
    PMID: 22217449 DOI: 10.1016/j.etp.2011.11.005
    Species of Phyllanthus have traditionally been used for hundreds of years for treating many ailments including diabetes, anemia, bronchitis and hepatitis. The present study aims to investigate the cytotoxic and apoptotic effects of methanol (PWM), hexane (PWH) and ethyl acetate (PWE) extracts from the leaves of the endemic plant Phyllanthus watsonii Airy Shaw (Phyllanthaceae) on MCF-7 human breast cancer cells. We observed that the PWM, PWH and PWE extracts were cytotoxic and selectively inhibited the growth and proliferation of MCF-7 cells compared to untreated control in a dose dependent manner with an IC(50) of 12.7 ± 4.65, 7.9 ± 0.60 and 7.7 ± 0.29 μg/ml, respectively. However, the extracts were not toxic at these concentrations to normal human lung fibroblast MRC-5 cells. Cell death induced by PWM, PWH and PWE extracts were mainly due to apoptosis which was characterized by apoptotic morphological changes and a nuclear DNA fragmentation. Caspase-3 activation following P. watsonii extracts treatment was also evident for apoptotic cell death which was preceded by an S phase cell cycle perturbation. The results suggested that the cytotoxic activity of P. watsonii extracts was related to an early event of cell cycle perturbation and a later event of apoptosis. Hence, P. watsonii displays potential to be further exploited in the discovery and development of new anticancer agents.

    PMID: 20450401 DOI: 10.1902/jop.2010.090648
    In dental implant treatment, the long-term prognosis is dependent on the biologic seal formed by the soft tissue around the implant. The in vitro investigation of the implant-soft tissue interface is usually carried out using a monolayer cell-culture model that lacks a polarized-cell phenotype. This study developed a tissue-engineered three-dimensional oral mucosal model (3D OMM) to investigate the implant-soft tissue interface.

  7. Occupational pressure-targeting organisational factors to ameliorate occupational dysfunction
    Loh SY, Than W, Quek KF
    J Occup Rehabil, 2011 Dec;21(4):493-500.
    PMID: 21365305 DOI: 10.1007/s10926-011-9287-3
    INTRODUCTION: Chronic pressure at work has debilitating impact on healthcare employers (e.g. reduced productivity, high costs, poor patient care) and on female healthcare employees (e.g. sickness, dysfunction). This paper highlights relationship at work as the key occupational source of work-stress which is organisational in nature.

    METHODS: A cross-sectional study (n = 230) was conducted using the Pressure Management Inventory on several female dominated health professions within a large public hospital. Analysis of variance was used to show relationship between sources and outcome of pressure. Linear regressions were used to predict which sources of pressure (IV) was linked to the outcomes of occupational pressure (DV).

    RESULTS: The number one source of occupational pressure is relationships at work (i.e. with supervisors), and not workload. 'Relationship' is also the key predictor of several negative outcomes of pressure at work. Analysis of variance showed significant differences in two sources of pressures, i.e. Workload (P = 0.04) and Home-work balance (P = 0.03).

    CONCLUSION: This paper provides insights into the occupational pressure of women health professionals by highlighting the organisational sources of pressure and the implications for preventing occupational dysfunction secondary to stress at work.

  8. Fulltext Fabrication of silver nanoparticles doped in the zeolite framework and antibacterial activity
    Shameli K, Ahmad MB, Zargar M, Yunus WM, Ibrahim NA
    Int J Nanomedicine, 2011;6:331-41.
    PMID: 21383858 DOI: 10.2147/IJN.S16964
    Using the chemical reduction method, silver nanoparticles (Ag NPs) were effectively synthesized into the zeolite framework in the absence of any heat treatment. Zeolite, silver nitrate, and sodium borohydride were used as an inorganic solid support, a silver precursor, and a chemical reduction agent, respectively. Silver ions were introduced into the porous zeolite lattice by an ion-exchange path. After the reduction process, Ag NPs formed in the zeolite framework, with a mean diameter of about 2.12-3.11 nm. The most favorable experimental condition for the synthesis of Ag/zeolite nanocomposites (NCs) is described in terms of the initial concentration of AgNO(3). The Ag/zeolite NCs were characterized by ultraviolet-visible spectroscopy, powder X-ray diffraction, transmission electron microscopy, scanning electron microscopy, energy dispersive X-ray fluorescence, and Fourier transform infrared. The results show that Ag NPs form a spherical shape with uniform homogeneity in the particle size. The antibacterial activity of Ag NPs in zeolites was investigated against Gram-negative bacteria (ie, Escherichia coli and Shigella dysentriae) and Gram-positive bacteria (ie, Staphylococcus aureus and methicillin-resistant Staphylococcus aureus) by disk diffusion method using Mueller-Hinton agar at different sizes of Ag NPs. All of the synthesized Ag/zeolite NCs were found to have antibacterial activity. These results show that Ag NPs in the zeolite framework can be useful in different biological research and biomedical applications.

  9. Fulltext High cell density and latent membrane protein 1 expression induce cleavage of the mixed lineage leukemia gene at 11q23 in nasopharyngeal carcinoma cell line
    Yee PH, Sim SP
    J Biomed Sci, 2010;17:77.
    PMID: 20858288 DOI: 10.1186/1423-0127-17-77
    Nasopharyngeal carcinoma (NPC) is commonly found in Southern China and South East Asia. Epstein-Barr virus (EBV) infection is well associated with NPC and has been implicated in its pathogenesis. Moreover, various chromosome rearrangements were reported in NPC. However, the underlying mechanism of chromosome rearrangement remains unclear. Furthermore, the relationship between EBV and chromosome rearrangement with respect to the pathogenesis of NPC has not been established. We hypothesize that during virus- or stress-induced apoptosis, chromosomes are initially cleaved at the base of the chromatin loop domain structure. Upon DNA repair, cell may survive with rearranged chromosomes.

  10. A phone-counseling smoking-cessation intervention for male Chinese restaurant workers
    Burton D, Zeng XX, Chiu CH, Sun J, Sze NL, Chen Y, et al.
    J Community Health, 2010 Dec;35(6):579-85.
    PMID: 20186474 DOI: 10.1007/s10900-010-9244-7
    We sought to develop a smoking-cessation intervention for male Chinese restaurant workers in New York City that required no seeking out by participants; provided support over a relatively long period of time; and was responsive to participants' cultural backgrounds and daily lives. The resulting intervention consisted of a minimum of 9 proactive phone counseling sessions within a 6-month period for each participant recruited at his worksite. All activities were conducted in Chinese languages. The efficacy of this proactive phone-counseling intervention was assessed in a pretest/posttest design comparing baseline smoking with smoking 6 months after the intervention ended. Of 137 male employees recruited at their restaurants, 101 (median age 40.5) participated in the phone-counseling intervention in 2007-2008, with 75 completing the program with at least 9 counseling calls. We found a linear increase in smoking cessation from 0% at Call 1 to 50.7% at Call 9 for 75 men who completed the program, and we found for all 101 participants a 32.7% intent-to-treat cessation rate for 6 months post-end of program, adjusted to 30.8% by saliva cotinine assessments. The results indicate that combining field outreach with phone counseling over an extended period of time can facilitate smoking cessation for population groups whose environments do not support efforts to quit smoking.

  14. Eldecalcitol (ED-71), an analog of 1α,25-dihydroxyvitamin D3 as a potential anti-cancer agent for oral squamous cell carcinomas
    Shintani T, Rosli SNZ, Takatsu F, Choon YF, Hayashido Y, Toratani S, et al.
    J Steroid Biochem Mol Biol, 2016 11;164:79-84.
    PMID: 26444325 DOI: 10.1016/j.jsbmb.2015.09.043
    We have previously reported that 1,25(OH)2D3 inhibits NF-κB activity and thus inhibits growth of OSCC cells in serum-free culture and down-regulates HBp17/FGFBP-1 expression, which is important for cancer cell growth and angiogenesis. Here, we have investigated the effects of ED-71, an analog of vitamin D3 (VD) on OSCC cell lines in serum-free culture. It is known that ED-71 has a stronger inhibitory effect on bone resorption compared to VD and other VD analogs. To the best of our knowledge, there was no report examining the potential of ED-71 as an anti-cancer agent for OSCC. We found that ED-71 is able to inhibit the growth of cancer cell lines at a concentration of hundred times lower than calcitriol. As Cyp24A1 was reportedly induced in cancer cells, we measured the expression of CYP24A1 in OSCC cell lines (NA and UE), A431 epidermoid carcinoma and normal fibroblast cell (gfi) in serum-free culture. As a result, CYP24A1 mRNA and the protein expression in the OSCC cells treated with ED-71 increased in a dose-dependent manner. However, in vivo experiment, in which the A431 cells were implanted in mice, tumor formation was reduced by the ED-71 treatment with no significant difference between Cyp24A1 expression in the tumors of ED-71-treated and control group, as analyzed by western blotting and immunohistochemistry. These results suggest that ED-71 is a potential anti-cancer agent for OSCC.

  15. Des-aspartate angiotensin I (DAA-I) reduces endothelial dysfunction in the aorta of the spontaneously hypertensive rat through inhibition of angiotensin II-induced oxidative stress
    Loh WM, Ling WC, Murugan DD, Lau YS, Achike FI, Vanhoutte PM, et al.
    Vascul. Pharmacol., 2015 Aug;71:151-8.
    PMID: 25869508 DOI: 10.1016/j.vph.2015.03.011
    Des-aspartate angiotensin I (DAA-I), an endogenous nonapeptide, counteracts several effects of angiotensin II on vascular tone. The aim of this study was to investigate the acute protective effect of DAA-I on endothelial function in the spontaneously hypertensive rat (SHR) as well as its effect on angiotensin II-induced contractions and oxidative stress. Aortic rings were incubated with DAA-I (0.1μM) for 30min prior to the assessment of angiotensin II-induced contractions (0.1nM-10μM) in WKY and SHR aortas. Total nitrate and nitrite levels were assessed using a colorimetric method and reactive oxygen species (ROS) were measured by dihydroethidium (DHE) fluorescence and lucigenin-enhanced chemiluminescence. The effect of DAA-I was also assessed against endothelium-dependent and -independent relaxations to acetylcholine and sodium nitroprusside, respectively. Angiotensin II-induced contractions were significantly reduced by DAA-I, losartan and tempol. Incubation with ODQ (soluble guanylyl cyclase inhibitor) and removal of the endothelium prevented the reduction of angiotensin II-induced contractions by DAA-I. Total nitrate and nitrite levels were increased in DAA-I, losartan and tempol treated-SHR tissues while ROS level was reduced by DAA-I and the latter inhibitors. In addition, DAA-I significantly improved the impaired acetylcholine-induced relaxation in SHR aortas whilst sodium nitroprusside-induced endothelium-independent relaxation remained unaffected. The present findings indicate that improvement of endothelial function by DAA-I in the SHR aorta is mediated through endothelium-dependent release of nitric oxide and inhibition of angiotensin II-induced oxidative stress.

    PMID: 10483028 DOI: 10.1191/096120399678840747
    OBJECTIVE: To validate the Medical Outcomes Study Family and Marital Functioning Measures (FMM and MFM) in a multi-ethnic, urban Asian population in Singapore.
    METHODS: English speaking Chinese, Malay or Indian SLE patients (n=120) completed a self-administered questionnaire containing the FFM and MFM at baseline, after 2 weeks and after 6 months. Lupus activity, disease-related damage and quality of life were assessed using the British Isles Lupus Assessment Group (BILAG), Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index and SF-36 Health Survey respectively. Scale psychometric properties were assessed through factor analysis, Cronbach's alpha, quantifying test-retest differences and known-groups construct validity.
    RESULTS: Factor analysis of scores obtained at baseline and after 6 months identified 3 factors corresponding to the FFM (1 factor) and the MFM (2 factors). Both scales showed acceptable internal consistency, with Cronbach's alpha of 0.95 for the FFM and 0.70 for the MFM. Mean (s.d.) test-retest differences were -0.31 (3.82) points for the FFM and -0.70 (4.26) points for the MFM. Eleven out of 13 a priori hypotheses relating both the FFM and MFM to demographic, disease and quality of life variables were confirmed, supporting the construct validity of these scales.
    CONCLUSION: The FFM and MFM are valid and reliable measures of family and marital functioning in a multi-ethnic cohort of Asian SLE patients in Singapore.

  17. Polyphenol-enriched extract of oil palm fronds (Elaeis guineensis) promotes vascular relaxation via endothelium-dependent mechanisms
    Abeywardena M, Runnie I, Nizar M, Suhaila M, Head R, Suhaila Momamed

    PMID: 12492636
    Plant-based polyphenolic compounds have been reported to possess cardiovascular health benefits. Several dietary sources, including herbs and spices, fruits and vegetables, and tea and wine, contain an array of biologically active compounds that have been shown to be effective in retarding oxidation of low-density lipoproteins (LDL) and promoting vascular relaxation. In the present study four different plant sources, both edible and non-edible, were evaluated for potential activity. Organic extracts enriched in polyphenols were prepared from palm fronds (Elaesis guineensis); lemongrass (Cymbopogon citrates); papaya shoots (Carica papaya) and green chilli (Capsicum frutescenes) and tested for their ability to prevent in vitro oxidation of LDL, and for potential vascular relaxation actions. Rings of rat thoracic aorta and isolated perfused mesenteric vascular beds were mounted in organ baths, contracted using a half-maximal dose of noradrenaline and exposed to cumulative additions of test extracts. Palm frond extract resulted in considerable relaxation (>75%) in both preparations and was found to be endothelium-dependent as removal of endothelium or inhibition of endogenous nitric oxide (NO) led to a total loss in relaxant activity. Lemongrass extract caused a greater relaxation action in the mesenteric preparation compared to aortic rings, and appears to be mediated via NO-independent and non-prostanoid mechanisms. Of the extracts tested, palm fronds also demonstrated the highest antioxidant capacity, as determined by the ferric reducing activity/potential assay, and resulted in a significant delay (P < 0.05) in the oxidation of LDL. Collectively, these preliminary findings lend further support to the potential cardiovascular actions of plant polyphenols and also identify oil palm fronds as containing constituents that promote vascular relaxation via endothelium-dependent mechanisms.

  18. Antimicrobial activity of Cassia alata from Malaysia
    Ibrahim D, Osman H
    J Ethnopharmacol, 1995 Mar;45(3):151-6.
    PMID: 7623478
    Ethanolic extract of Cassia alata leaves was investigated for its antimicrobial activities on several microorganisms including bacteria, yeast, dermatophytic fungi and non-dermatophytic fungi. In vitro, the extract exhibited high activity against various species of dermatophytic fungi but low activity against non-dermatophytic fungi. However, bacterial and yeast species showed resistance against in vitro treatment with the extract. The minimum inhibitory concentration (MIC) values of the extract revealed that Trichophyton mentagorphytes var. interdigitale, Trichophyton mentagrophytes var. mentagorophytes, Trichophyton rubrum and Microsporum gypseum had the MIC of 125 mg/ml, whereas Microsporum canis had the MIC of 62.5 mg/ml. The inhibition can be observed on the macroconidia of Microsporum gypseum which resulted in structural degeneration beyond repair. The mechanism of inhibition can be related to the cell leakage as observed by irregular, wrinkle shape and loss in rigidity of the macroconidia.

    PMID: 12345736
    PIP:
    In 1991, the Family Planning Association (FPA) of the Malaysian state of Perak initiated a community-based development project in the remote Aborigine village of Kampung Tisong. The community consists of approximately 34 households who survive on an average income of about US $37. Malnutrition is pervasive, even minor ailments cause death, more serious afflictions are prevalent, and the closest government clinic is 20 kilometers away and seldom used by the Aborigines. 70% of the children have access to education, but parental illiteracy is a serious educational obstacle. The goals of the FPA program are to 1) promote maternal and child health and responsible parenthood, 2) provide health education, 3) encourage women to seek self-determination, and 4) encourage the development of self-reliance in the community as a whole. The first step was to survey the community's culture, beliefs, and health status with the help of the Aborigines Department and the village headman. After a series of preliminary meetings with other agencies, the FPA began to provide activities including health talks, health courses and demonstrations, medical examinations and check-ups, and first aid training. Environmental protection and sanitation measures were included in the educational activities, and following the traditional "mutual aid system," a small plot of land was cleared for vegetable production. Vegetable gardens and needlecraft will become income-producing activities for the women. Attempts to motivate the women to use family planning have been hindered by the fact that the health of 2 women deteriorated after they began using oral contraceptives. Positive changes are occurring slowly and steadily, however, and the FPA has been instrumental in having the settlement included in a program for the hardcore poor which will provide new housing and farming projects.
