Improved protection from velogenic Newcastle disease virus challenge following multiple immunizations with plasmid DNA encoding for F and HN genes

Loke CF, Omar AR, Raha AR, Yusoff K

Vet Immunol Immunopathol, 2005 Jul 15;106(3-4):259-67.
PMID: 15963824

Specific-pathogen free (SPF) chickens were inoculated with the plasmid constructs encoding the fusion (F) and haemagglutinin-neuraminidase (HN) glycoproteins of Newcastle disease virus (NDV), either individually or in combination and challenged with velogenic NDV. The antibody level against NDV was measured using commercial enzyme linked immunosorbent assay (ELISA). In the first immunization regimen, SPF chickens inoculated twice with NDV-F or NDV-HN constructs elicited antibody responses 1 week after the second injection. However, the levels of the antibody were low and did not confer significant protection from the lethal challenge. In addition, administration of the plasmid constructs with Freund's adjuvant did not improve the level of protection. In the second immunization regimen, chickens inoculated twice with the plasmid constructs emulsified with Freund's adjuvant induced significant antibody titers after the third injection. Three out of nine (33.3%) chickens vaccinated with pEGFP-HN, five of ten (50.0%) chickens vaccinated with pEGFP-F and nine of ten (90.0%) chickens vaccinated with combined pEGFP-F and pEGFP-HN were protected from the challenge. No significant differences in the levels of protection were observed when the chickens were vaccinated with linearized pEGFP-F. The results suggested that more than two injections with both F and HN encoding plasmid DNA were required to induce higher level of antibodies for protection against velogenic NDV in chickens.

Estimation and influence of physicochemical properties and chemical fractions of surface sediment on the bioaccessibility of Cd and Hg contaminant in Langat River, Malaysia

Kadhum SA, Ishak MY, Zulkifli SZ

Environ Geochem Health, 2017 Oct;39(5):1145-1158.
PMID: 27848092 DOI: 10.1007/s10653-016-9883-4

This study applied the use of sequential extraction technique and simple bioaccessibility extraction test to quantify the bioavailable fractions and the human bioaccessible concentration of metals collected from nine stations in surface sediment of the Langat River. The concentrations of total and bioaccessible metals from different stations were in the range of 0.49-1.04, 0.10-0.32 μg g-1 for T-Cd, Bio-Cd, respectively, and 12.9-128.03, 2.06-8.53 μg kg-1 for T-Hg, Bio-Hg, respectively. The results revealed highest R-Bio-Cd in Banting station (55.3 %), while the highest R-Bio-Hg was in Kajang station (49.61 %). The chemical speciation of Cd in most sampling stations was in the order of oxidisable-organic > residual > exchangeable > acid-reducible, while speciation of Hg was in the order of exchangeable > residual > oxidisable-organic > acid-reducible. The correlation matric of mean content showed that the TOM, particle size and Mg++ in polluted surface sediments was highly correlated with total mercury. The PCA showed that the main factors influencing the bioaccessibility of Hg in surface sediments were the sediment TOM, F1 (EFLE) and F3 (oxidation-organic), while the factor influencing the bioaccessibility of Cd was the F3 (oxidation-organic) and T-Cd.
Fulltext Frequency patterns of core constipation symptoms among the Asian adults: a systematic review

Patimah AW, Lee YY, Dariah MY

BMC Gastroenterol, 2017 Nov 02;17(1):115.
PMID: 29096625 DOI: 10.1186/s12876-017-0672-z

BACKGROUND: In clinical practice, assessment of constipation depends on reliability, consistency and frequency of several commonly reported or core symptoms. It is not known if frequency patterns of constipation symptoms in adults are different between the West and the East. This review aimed to describe core constipation symptoms and their frequency patterns among the Asian adults.
METHODS: Articles published in PubMed, MEDLINE, CINAHL and Science Direct from 2005 to 2015 were searched systematically. Studies were included if constipation satisfied the Rome II and or III criteria. Study populations consisted of Asian adults above 18 years old and with sample size above 50.
RESULTS: Of 2812 articles screened, 11 met the eligibility criteria. Constipation among Asian adults was characterized by three core symptoms of 'straining' at 82.8%, 'lumpy and hard stool' at 74.2% and 'sensation of incomplete evacuation' at 68.1% and the least frequent symptom was 'manual maneuver to facilitate defecation' at 23.3%. There was heterogeneity in frequency patterns of core symptoms between different Asian studies but also differences in core symptoms between constipation subtypes of functional constipation and irritable bowel syndrome with constipation.
CONCLUSIONS: In general, Asian adults perceive constipation symptoms in a similar but not equivalent manner to the West. Recognition of core symptoms will increase the diagnostic confidence of constipation and its subtypes but more studies of the various specific Asian populations are needed to address their differences.
Fulltext Monitoring butterflies using counts of puddling males: A case study of the Rajah Brooke's Birdwing (Trogonoptera brookiana albescens)

Phon CK, Kirton LG, Norma-Rashid Y

PLoS One, 2017;12(12):e0189450.
PMID: 29232405 DOI: 10.1371/journal.pone.0189450

The Rajah Brooke's Birdwing, Trogonoptera brookiana, is a large, iconic butterfly that is facing heavy commercial exploitation and habitat loss. Males of some subspecies exhibit puddling behavior. A method of conservation monitoring was developed for subspecies albescens in Ulu Geroh, Peninsular Malaysia, where the males consistently puddle in single-species aggregations at stable geothermal springs, reaching well over 300 individuals when the population is at its highest. Digital photography was used to conduct counts of numbers of males puddling. The numbers of birdwings puddling were significantly correlated with counts of birdwings in flight, but were much higher. The numbers puddling during the peak hour were correlated with numbers puddling throughout the day and could be predicted using the numbers puddling at an alternative hour, enabling flexibility in the time of counts. Average counts for three images taken at each puddle at three peak hours between 1400-1600 hours over 2-3 days were used as a monthly population index. The numbers puddling were positively associated with higher relative humidity and brightness during monitoring hours. Monthly counts of birdwings from monitoring of puddles over a period of two years are presented. The minimum effort required for a monitoring program using counts of puddling males is discussed, as well as the potential of using the method to monitor other species of puddling butterflies.

Evaluation and assessment of baseline metal contamination in surface sediments from the Bernam River, Malaysia

Kadhum SA, Ishak MY, Zulkifli SZ

Environ Sci Pollut Res Int, 2016 Apr;23(7):6312-21.
PMID: 26614452 DOI: 10.1007/s11356-015-5853-0

The Bernam River is one of the most important rivers in Malaysia in that it provides water for industries and agriculture located along its banks. The present study was conducted to assess the level of contamination of heavy metals (Cd, Ni, Cr, Sn, and Fe) in surface sediments in the Bernam River. Nine surface sediment samples were collected from the lower, middle, and upper courses of the river. The results indicated that the concentrations of the metals decreased in the order of Sn > Cr > Ni > Fe > Cd (56.35, 14.90, 5.3, 4.6, and 0.62 μg/g(1) dry weight). Bernam River sediments have moderate to severe enrichment for Sn, moderate for Cd, and no enrichment for Cr, Ni, and Fe. The contamination factor (CF) results demonstrated that Cd and Sn are responsible for the high contamination. The pollution load index (PLI), for all the sampling sites, suggests that the sampling stations were generally unpolluted with the exception of the Bagan Tepi Sungai, Sabak Bernam, and Tanjom Malim stations. Multivariate techniques including Pearson's correlation and hierarchical cluster analysis were used to apportion the various sources of the metals. The results suggested that the sediment samples collected from the upper course of the river had lower metal concentrations, while sediments in the middle and lower courses of the river had higher metal concentrations. Therefore, our results can be useful as a baseline data for government bodies to adopt corrective measure on the issues related to heavy metal pollution in the Bernam River in the future.

Abubakar A, Ishak MY, Makmom AA

Environ Sci Pollut Res Int, 2021 Oct;28(39):54339-54361.
PMID: 34402002 DOI: 10.1007/s11356-021-15890-3

The interaction and the interplay of climate change with oil palm production in the Southeast Asia region are of serious concern. This particularly applies in Malaysia due to its rank as the second largest palm oil producer in the world. The anthropogenic activities and the agroecological practices in oil palm plantation, including excessive use of fertilisers, bush fire due to land clearing, and cultivation on peatland, have exacerbated the effects of climate change featuring extreme events, drought, flooding, heatwave, as well as infestation of pest and diseases. These adverse impacts on oil palm production highlight the significance of deploying effective adaptation strategies. The study aims to examine the impact of climate change on oil palm production and identify the farmers' adaptation strategies to the impacts of climate change in Malaysia. This study was conducted a comprehensive review of the articles published from 2000 to 2021 in the contexts of climate change and oil palm production in Malaysia. The review shows that climate change has a range of impacts on the oil palm production in Malaysia. As a result, several adaptation options were identified, such as breeding of hybrid varieties that are tolerant and resistant to heat; sustainable management of soil; pit and tranches to enhance water management in plantation areas; minimal use of fertilisers, herbicides, and pesticides; zero burning; and minimum tillage. The reviewed studies recommended the following to mitigate the adverse impacts of climate change: sustainable national policy on climate change, conservation of the existing carbon stock, effective management of tropical rainforest biodiversity, afforestation for carbon sequestration, and reduction in greenhouse gas (GHG) emission.

Tzar MN, Mustakim S, Yusoff H, Tap RM

Malays J Pathol, 2024 Apr;46(1):71-78.
PMID: 38682846

Invasive aspergillosis is the second most common invasive human mycosis but susceptibility data of Aspergillus species is limited. Antifungal treatment of aspergillosis is often done empirically without knowing the true susceptibility. Therefore, we aimed to determine antifungal susceptibility of Aspergillus species isolated from various clinical specimens over a 1-year period. We identified 28 Aspergillus isolates by sequencing the internal transcribed spacer (ITS) and β-tubulin genes and performed antifungal susceptibility testing on these isolates using Sensititre YeastOne. The isolates were identified as Aspergillus niger (60.7%), A. fumigatus (21.4%), A. flavus (10.7%), A. chevalieri (3.6%) and A. tubingensis (3.6%). Based on the European Committee on Antimicrobial Susceptibility Testing (EUCAST) Antifungal Clinical Breakpoint for Aspergillus spp., 16/17 (94.1%) A. niger isolates were susceptible to amphotericin B, all six isolates (100%) of A. fumigatus were susceptible to amphotericin B, itraconazole and voriconazole, but only 5/6 (83.3%) A. fumigatus were susceptible to posaconazole. Meanwhile, all three (100%) A. flavus isolates were susceptible to itraconazole. There are no other breakpoints established by the EUCAST for other antifungal-species combinations. In conclusions, Aspergillus niger remains the most commonly isolated species from clinical specimens and Aspergillus isolates at our centre are still largely susceptible to amphotericin B, echinocandins and most azoles. This information is valuable in guiding antifungal therapy in the treatment of aspergillosis.
Fulltext Evaluating the perception of farmers towards pesticides and the health effect of pesticides: A cross-sectional study in the oil palm plantations of Papar, Malaysia

PMID: 32189983 DOI: 10.2478/intox-2019-0003

Agriculture is an important occupation in Malaysia that generates a major portion of the national revenue. Similar to the rest of the world, pesticides are used to boost agricultural production in Malaysian farms. However, chemical pesticides are associated with human health hazard and are not environment-friendly as they persist in nature for long periods of time. Therefore, pesticide use should be reduced and farmers should be trained on correct and/or alternative ways of pesticide use. In this cross-sectional study, we surveyed 19 palm oil plantations in the Sabah district of Malaysia and evaluated the perception of the workers towards pesticide use and awareness regarding the health effects post-pesticide exposure. Analysis of the survey shows that most of the workers among the 270 respondents were 30-year-old males with average education, and belonged to the low income group. Majority opined that they were aware of the health hazards of pesticide use and suffered from symptoms (with mean duration of three days) such as vomiting, diarrhea, skin irritation, and dizziness. Surprisingly, the opinion was almost equally divided on whether they perceived pesticides to be the cause of their health problems, and a major percentage did not avail medical help. Most of the workers responded that they did not receive any training in pesticide handling and used partial personal protective equipment (glasses, hats, shirt, and gloves) during working hours. Interestingly, a large percentage responded that they would not read the safety material even if it was provided. These observations clearly highlight the urgency of improving the awareness, education, and attitude of these plantation workers towards the short- and long-term effects of pesticide use. They should also be educated about alternative and eco-friendly ways of farming. Finally, the plantation management should intervene and proactively advocate the use of safe farming practices.
Fulltext The challenge of getting a high quality of RNA from oocyte for gene expression study

Maisarah Y, Hashida HN, Yusmin MY

Vet Res Forum, 2020;11(2):179-184.

The extraction of intact RNA from oocyte is quite challenging and time-consuming. A standard protocol using commercial RNA extraction kit, yields a low quantity of RNA in oocytes. In the past, several attempts in getting RNA for gene expression study ended up with a few different modified methods. Extraction of high-quality RNA from oocyte is important before further downstream analyses such as reverse transcription-polymerase chain reaction, quantitative polymerase chain reaction, or northern blot analysis. In this review, the efficiency of RNA extraction methods from all species oocytes was compared between published articles and our research to gather all possible methods of RNA extraction. Two different methods of RNA extraction that were proposed from various experiments were reviewed to determine the best method of RNA extraction from the oocyte. Modified TRIzol method can be concluded as an efficient RNA extraction method especially for good RNA from oocytes. Meanwhile, comparing RNA extraction kits to extract the RNA from oocytes or pre-implantation embryos, the micro RNA extraction kit type is the best. Therefore, an appropriate RNA extraction method is important to obtain high quality of total RNA for gene expression profiling analysis.

Bacteriostatic effect of Piper betle and Psidium guajava extracts on dental plaque bacteria

Fathilah AR, Rahim ZH, Othman Y, Yusoff M

Pak J Biol Sci, 2009 Mar 15;12(6):518-21.
PMID: 19580002

In this study, the bacteriostatic effect of Piper betle and Psidium guajava extracts on selected early dental plaque bacteria was investigated based on changes in the doubling time (g) and specific growth rates (micro). Streptococcus sanguinis, Streptococcus mitis and Actinomyces sp. were cultured in Brain Heart Infusion (BHI) in the presence and absence of the extracts. The growth of bacteria was monitored periodically every 15 min over a period of 9 h to allow for a complete growth cycle. Growth profiles of the bacteria in the presence of the extracts were compared to those in the absence and deviation in the g and micro were determined and analyzed. It was found that the g and mu were affected by both extracts. At 4 mg mL(-1) of P. betle the g-values for S. sanguinis and S. mitis were increased by 12.0- and 10.4-fold, respectively (p < 0.05). At similar concentration P. guajava increased the g-value by 1.8- and 2.6 -fold, respectively (p < 0.05). The effect on Actinomyces sp. was observed at a much lower magnitude. It appears that P. betle and P. guajava extracts have bacteriostatic effect on the plaque bacteria by creating a stressed environment that had suppressed the growth and propagation of the cells. Within the context of the dental plaque, this would ensure the attainment of thin and healthy plaque. Thus, decoctions of these plants would be suitable if used in the control of dental plaque.

PMID: 21242179 DOI: 10.1177/0734242X10387462

Solid waste collection and disposal are among the most vital services provided to about 700 770 residents of the city of Erbil in northern Iraq. As such, proper waste management systems that consider both the quantity and composition of domestic solid waste are strongly required to address the increasing amount of solid waste. Unfortunately, these essential data are not easily available. The present study sought to gather data on the quantity and composition of domestic solid waste collected from different quarters in Erbil, and the feasibility of recycling these wastes. The solid waste generation rate (GR), uncompacted density, and weight percentages of combustible and incombustible materials were determined based on the collected materials (i.e., food, plastic, paper, metal, glass and cloth). The results show that the average GR and uncompacted density were 0.654 kg capita(-1) day(-1) and 175.72 kg m(-3), respectively. The weight percentages of food, plastic, paper, metal, glass, and cloth as components of domestic solid waste were 79.34, 6.28, 5.9, 3.6, 3.42 and 1.45%, respectively.

Introduction: Family planning practice is important among the high-risk mothers. Thus, the knowledge, attitude and practice of family planning among health care workers are very important in influencing the use of contraception among them. The objective of this study was to determine level of knowledge, attitudes and practices related to contraception among doctors and nurses in Petaling District, Selangor, Malaysia. Methods: A cross-sectional study involving 300 doctors and nurses working in the Maternal and Child Health Unit from six large public health clin-ics in Petaling district was conducted in May 2019. A self-administered questionnaire was used for data collection. Results: A total of 109 doctors and 149 nurses participated in this study. The response rate was 86%. The median duration of service in KKM and working in MCH were 9 years (IQR 6.0) and 3 years (IQR 6.0) respectively. Majority (74%) had attended CME on family planning. The mean score of knowledge was 9.0 (out of 13) (SD 1.899). In terms of attitude, 51.6% would often suggest family planning to relatives or friends. Three common perceived barriers for effective counselling on family planning were too many patients (94.5%), time constraint (91.7%) and inadequate knowledge on contraception (60.4%). Common preferred methods of contraception among users were hormonal method (33.1%), followed by barrier (condom) method (29.5%). Medical officers had better knowledge score as compared to nurses (p

Introduction: Gestational diabetes mellitus is one of the most common complications during pregnancy which affects 15% of pregnant women globally. Gestational diabetes mellitus patients have seven times lifetime risk of developing type 2 diabetes compared to women with normal pregnancies. Despite these facts, gestational diabetes mellitus patients may not perceive themselves to be at risk for future diabetes. Thus, this study aimed to determine the perception of risk for developing diabetes and factors associated with high risk perception among gestational di-abetes mellitus patients in Johor Bahru. Methods: A cross sectional study was conducted between April to May 2019 among 200 gestational diabetes mellitus patients attending primary health clinics in Johor Bahru, Malaysia. Data was collected using Malay translated and validated Risk Perception Survey on Developing Diabetes questionnaire. Multiple logistic regression analysis was performed using SPSS version 24.0. Results: There were 200 cases which fulfilled the inclusion and exclusion criteria in this study. The mean (SD) age of gestational diabetes mellitus patients in this study was 32.2 (4.8) years. Majority of them were from Malay ethnicity (74.5%) and 42.5% obtained higher education. Of these, 77.0% perceived themselves as high risk for developing diabetes. Higher knowledge scores and greater personal control were significantly associated with high perceived risk for developing diabetes (Adj. OR 2.08; 95% CI: 1.02,4.25; p=0.045 and Adj. OR 2.32; 95% CI: 1.16,4.63; p=0.017 respectively). Conclusion: Majority of gestational diabetes mellitus patients in this study accurately perceived themselves as having a high risk to develop diabetes in the future. Nevertheless, health education needs to be individualized and strengthened to ensure more patients are aware of the risk. In addition, further studies are needed to translate perceived risk into preventive health behaviours.

Mohd Azim M, Amin S, Romano N, Arshad A, Yusoff F

Sains Malaysiana, 2017;46:2263-2271.

The yellowtail scad, Atule mate, forms important fisheries throughout the Indo-Pacific region. To know about the stock status of A. mate in Malaysia, various population parameters were measured, by utilizing length-frequency data, that included asymptotic length (L∞), growth coefficient (K), mortality rates (Z, F and M), exploitation level (E) and recruitment pattern of this species from Marudu Bay, Sabah, Malaysia. Total length and body weight relationship was estimated as W = 0.007TL3.148 (R2 = 0.937). The asymptotic length (L∞) and growth coefficient (K) were estimated 27.80 cm and 1.50 yr−1, respectively. Total mortality (Z), natural mortality (M) and fishing mortality (F) were found to be 4.53, 2.46 and 2.07 yr−1, respectively. The exploitation level (E) was estimated 0.46. It was showed that the recruitment pattern was continuous with two major peaks per year. Relative yield per recruit predicted a maximum exploitation rate (Emax) which was 0.55. The current E value (0.46) is lower than the optimum exploitation (E = 0.50) as well predicted Emax. Therefore, it could be concluded that stock of A. mate in the investigated area of Marudu Bay, Sabah is under exploited.

Sakinah Harith, Aryati Ahmad, Noor Aini Mohd Yusoff, Khor Wei Xin, Shariza Abdul Razak

Malaysian Journal of Public Health Medicine, 2017;17 Special(2):1-10.

The main objective of the study was to determine the factors associated with blood cholesterol level among staff in Universiti Sains Malaysia (USM). The study was a cross-sectional. One-hundred staff between 23 and 59 years of age were recruited in this study using convenient sampling at USM Health Campus. A questionnaire which includes sociodemographic characteristics, medical history, and red meat intake was used in the study. Anthropometric and biochemical assessment were measured. Blood cholesterol level was divided into two categories which were known as healthy range (<5.2mmol/L) and slight risk/high risk range (≥5.2mmol/L). The gender distribution of respondents for this study comprised of 40 male and 60 female. The age group (18 to 39) years and (40 to 59) years had a total of 40.3% and 63.2% of slightly risk or high risk blood cholesterol respectively; with the significant association between age group and blood cholesterol level (χ²=4.916,p=0.027). Besides, normal BMI group had 66.7% of respondents achieved healthy blood cholesterol level whereas underweight, overweight and obese group had 39.7% achieved healthy blood cholesterol with the significant association between BMI and blood cholesterol level (χ²=7.112,p=0.008). Moreover, daily or weekly intake of red meat showed that 65.0% of total respondents had a healthier blood cholesterol level compared to 51.0% of monthly, rarely, or none red meat intake group which achieved healthy blood cholesterol level. The result also showed a significant association between red meat intake and blood cholesterol (χ²=5.229, p=0.022), which indicating less red meat consumption is linked to high level of blood cholesterol level. Therefore, further investigation and future studies are needed to gain a clearer understanding of the association between these variables and blood cholesterol level.
