    Purpose: Cardiovascular disease (CVD) is the leading and the most critical type of chronic disease. Atherosclerosis is the most common cause of CVD. Inflammation has been progressively acknowledged as a vital and central player in the pathophysiology of atherosclerosis. Baccaurea angulata is an underutilized fruit of the island of Borneo. It was obtained from Bau, Sarawak, Malaysia. In our previous studies, B. angulata did not only increase antioxidant enzyme activities, but also slowed the lipid peroxidation process in high-cholesterol-fed rabbits. It was hypothesized that B. angulata fruit would exert an anti-inflammatory effect. This study, therefore, aimed at evaluating and comparing the effects of three different B. angulata whole fruit (WF) juice doses on 11 serum inflammatory biomarkers of atherosclerosis.

    Methods: Thirty-five male New Zealand white rabbits were divided into seven groups (n=5). Group CH was fed 1% cholesterol diet only, group C1 was fed 1% cholesterol diet and 0.5 ml/kg/day B. angulata WF juice, group C2 was fed 1% cholesterol diet and 1.0 ml/kg/day B. angulata WF juice, group C3 was fed 1% cholesterol diet and 1.5 ml/kg/day B. angulata WF juice, group N was fed standard pellet only, group N1 was fed standard pellet and 0.5 ml/kg/day B. angulata WF juice, and group N2 was fed standard pellet and 1.0 ml/kg/day B. angulata WF juice for 12 weeks.

    Results: The administration of the various juices reduced the concentrations of induced serum inflammatory biomarkers.

    Conclusion: This protective effect of B. angulata fruit against cardiovascular risk might be due to its polyphenol content.

    :The aim of this paper is to examine the impact of local government competition and environmental regulation intensity on regional innovation performance and its regional heterogeneity. Based on the theoretical mechanism of the aforementioned variables, this study uses the Chinese provincial panel data from 2001 to 2016. We use the super-efficiency data envelopment analysis (SE-DEA) to evaluate regional innovation performance. To systematically examine the impact of local government competition and environmental regulation intensity on regional innovation performance, we build a panel date model using the feasible generalized least squares (FGLS) method. The results indicate that: the regional innovation performance can be significantly improved through technological spillover; local governments compete for foreign direct investment (FDI) to participate in regional innovative production. Moreover, improvements in environmental regulation intensity enhance regional innovation performance through the innovation compensation effect. Our results show that the local governments tend to choose lower environmental regulation intensity to compete for more FDI, which has an inhibitory effect on regional innovation performance. Furthermore, due to regional differences in factor endowments, economic reforms and economic development levels in Chinese provinces, there exists a significant regional consistency in the impact of local government competition and environmental regulation intensity on regional innovation performance. Therefore, institutional arrangements and incentive constraints must be adopted to enhance regional innovation performance as well as to guide and foster the mechanism of green innovation competition among local governments. At the same time, considering the regional heterogeneity of local government competition and environmental regulation intensity affecting regional innovation performance, policy makers should avoid the "one-size-fits-all" strategy of institutional arrangements.

    The objective of current study was to determine the effect of fat supplement on physiological and reproductive performance of Holstein Friesian bulls during subtropical summer in Pakistan. Eighteen bulls were randomly divided into 3 treatment groups: (1) CTL, basal diet without fat supplementation; (2) FS100, basal diet with 100 g fat supplementation (Energizer-RP-10®, IFFCO, Johor, Malaysia); (3) FS200, basal diet with 200 g fat supplementation. Basal diet consisted of 50% green fodder (corn silage), 25% wheat straw, and 25% concentrate on dry matter basis. Diets were offered for 14 weeks from May to August 2016. The average daily temperature-humidity index ranged from 85 to 88 for the experimental period. The results indicated that there was no difference in dry matter intake, water intake, rectal temperature, pulse rate, and respiration rate among the treatment groups. Fat supplementation did not influence semen traits including sperm motility, progressive motility, amplitude of lateral head displacement, live-to-dead ratio, normal acrosomal ridge, plasma membrane integrity, and DNA integrity. The interaction of season with fat revealed that FA200 significantly increased post thaw semen motility and progressive motility during hot humid summer (P

    The city of Dhaka has been ranked repeatedly as the most polluted, the most populous, and the most unbearable city in the world. More than 19.5 million inhabitants live in Dhaka, and the population growth rate of urban areas in Bangladesh is almost double that of rural areas. Rapid urbanization is one of the leading contributors to water pollution in Dhaka and could prevent the country from achieving sustainable development. Therefore, this study estimates respondents' willingness to pay (WTP) to improve water pollution management systems and identifies factors that influence WTP in Dhaka. This study employed the contingent valuation method (CVM) to estimate WTP of the respondents. Data were collected using a structured questionnaire with CVM questions, which was distributed to households in the study areas. The results revealed that 67% of the respondents are willing to pay for an improved water pollution management system, while 31.8% of households are unwilling to pay. The study also found that socio-economic factors (e.g., income and education) and perception significantly influence WTP. Therefore, this paper will provide directives for policymakers in developing an effective policy framework, as well as sensitize all stakeholders to the management of water pollution in Dhaka. The study suggests that social institutions, financial institutions, banks, non-government organizations (NGOs), insurance companies, and the government could provide effective outreach programs for water pollution management as part of their social responsibility.

    BACKGROUND: The objective of this study is to evaluate the effectiveness of pharmacist intervention in improving disease knowledge, adherence to treatment, health-related quality of life (HRQoL) and direct cost of treatment. The study also documents patient satisfaction with pharmacist counselling as a quality control measure.

    METHODS/DESIGN: This is a randomized, single-blind, two-arm, controlled trial in patients with rheumatoid arthritis visiting outpatient rheumatology clinics in Karachi, Pakistan. We will enroll patients with established diagnosis of rheumatoid arthritis over 3 months. The patients would be randomized through a computer-generated list into the control group, i.e., usual care or into the intervention group, i.e., pharmaceutical care, in a ratio of 1:1, after providing signed written consent. The study will take place in two patient-visits over the course of 3 months. Patients in the intervention group would receive intervention from the pharmacist while those in the control group will receive usual care. Primary outcomes include change in mean score from baseline (week 0) and at follow up (week 12) in disease knowledge, adherence to medications and rehabilitation/physical therapy. The secondary outcomes include change in the mean direct cost of treatment, HRQoL and patient satisfaction with pharmacist counselling.

    DISCUSSION: This is a novel study that evaluates the role of the pharmacist in improving treatment outcomes in patients with rheumatoid arthritis. The results of this trial could set the foundation for future delivery of care for this patient population in Pakistan. The results of this trial would be published in a peer-reviewed journal.

    This paper discussed the effects of modified metakaolin (MK) with nano-silica (NS) on the mechanical properties and durability of concrete. In the first phase, trial mixes of concrete were prepared for achieving the desired value of the 28 days compressive strength, and the charge passed in rapid chloride permeability test (RCPT). In the second phase, statistical analysis was performed on the experimental results using the response surface method (RSM). The RSM was applied for optimizing the mix proportions for the required performance by exploiting the relationship between the mix characteristics and the corresponding test results. A blend of 10% MK + 1% NS as part of cement replacement exhibited the highest mechanical properties and durability characteristics of concrete; concrete mix showed that the 28-days compressive strength (CS) was 103 MPa, which was 15% greater than the CS of the control mix without MK or NS. The same mix showed more than 40% higher flexural and split-tensile strength than the control mix; also it resulted in a reduction of 73% in the rapid chloride permeability value. ANOVA technique was used for optimizing the nano-silica and metakaolin content for achieving maximum compressive strength and minimum RCPT value. Statistical analysis using ANOVA technique showed that the maximum compressive strength and lowest RCPT value could be achieved with a blend of 10% MK and 1.55% NS.

    Nanoparticles (NPs) are, frequently, being utilized in multi-dimensional enterprises. Silver nanoparticles (AgNPs) have attracted researchers in the last decade due to their exceptional efficacy at very low volume and stability at higher temperatures. Due to certain limitations of the chemical method of synthesis, AgNPs can be obtained by physical methods including sun rays, microwaves and ultraviolet (UV) radiation. In the current study, the synthesis of pullulan mediated silver nanoparticles (P-AgNPs) was achieved through ultraviolet (UV) irradiation, with a wavelength of 365 nm, for 96 h. P-AgNPs were formed after 24 h of UV-irradiation time and expressed spectra maxima as 415 nm, after 96 h, in UV-vis spectroscopy. The crystallographic structure was "face centered cubic (fcc)" as confirmed by powder X-ray diffraction (PXRD). Furthermore, high resolution transmission electron microscopy (HRTEM) proved that P-AgNPs were covered with a thin layer of pullulan, with a mean crystalline size of 6.02 ± 2.37. The average lattice fringe spacing of nanoparticles was confirmed as 0.235 nm with quasi-spherical characteristics, by selected area electron diffraction (SAED) analysis. These green synthesized P-AgNPs can be utilized efficiently, as an active food and meat preservative, when incorporated into the edible films.

    The ultrasound wave assisted synthesis of a novel ZnWO3/rGO hybrid nono composition (ZnWO3/rGO HNC) as a high performance sensor for formaldehyde (FA) has been reported. Different techniques of analysis such as XRD, FE-SEM, TGA, XPS, HRTEM and BET were applied for morphological and spectroscopic characterization of the ZnWO3/rGO HNC. The sensing evaluation of the constructed sensor showed high selectivity, sensitivity and a linear correlation between achieved responses and concentration of target gas (1-10 ppm) with R2 = 0.993 at temperature of 95 °C. The determination of FA was validated and performed using gas chromatography-mass spectrometry combined by solid phase micro-extraction after derivatization with O-(2,3,4,5,6-pentafluoro-benzyl)-hydroxylamine hydrochloride. Validation was carried out in terms of limit of detection linearity, precision, and recovery. The mechanistic evaluation of sensing behavior of the ZnWO3/rGO HNC was interpreted based on large specific surface area (SSA) to volume, mesoporous structure and the heterojunction between rGO and ZnWO3 at the interface between the rGO and ZnWO3.

    Aphids are major pests of wheat crop in Pakistan inflicting considerable economic losses. A better knowledge of landscape scale spatial distribution of aphids and their natural enemies could be used to improve integrated pest management programs. Therefore, the present study aimed to document spatio-temporal variations in populations of wheat aphids and their natural enemies in Pakistan. The 2-year survey study was carried out at ten experimental farms located in five districts of four contrasted agro-ecological zones of eastern Pakistan (Punjab area) i.e. District Chakwal in arid zone, Gujranwala in rice-cropped zone, Faisalabad in central mixed-cropped zone, and Khanewal and Multan in cotton-cropped zone. The dominant aphid species i.e. Schizaphis graminum, Rhopalosiphum padi, R. maidis and Sitobion avenae varied significantly among the five districts surveyed. The population of S. graminum was observed more abundant in arid, R. padi in rice, S. avenae in aird and rice, and R. maidis in cotton-I zones. Aphids ended their population dynamics on 25th March in central mixed-cropped zone and 12th April in other three zones. Various species of natural enemies, mainly Coccinella septumpunctata, C. undecimpunctata, Menochilus sexmaculata, Chrysoperla carnea, Syrphidae and parasitoid mummies were inconsistently observed in four agro-ecological zones. The population of C. septumpunctata, was observed more abundant in rice zone, C. undecimpunctata and C. carnea in cotton-I and arid zones, M. sexmaculata in cotton-I and II zones, Syrphidae in cotton-I zone and parasitoid mummies in rice and arid zones. There were no clear relationships between aphid and the natural enemy populations. The present study may serve as a baseline regarding distribution of wheat aphids and their natural enemies and the results provided insights for further studies on the potential top-down (natural enemies) versus bottom-up (fertilization and irrigation regimes) forces in management of wheat aphids in eastern Pakistan.

    BACKGROUND: Oral health is integral to systemic health. There is a growing body of evidence of an association between periodontal and systemic diseases. The aim of the study was to evaluate the awareness of dentists regarding link between oral and systemic health.

    MATERIALS AND METHODS: Data was collected using a self-administered pilot-tested questionnaire. Dentists awareness about link between oral and systemic link was assessed on five point likert scale. Data was entered and analysed using SPSS.

    RESULTS: Of the 588 dentists, 500 completed the questionnaire (response rate 85.03%). About 93% of the participants (mean age 25.82 ± 4.21 years) agreed that oral health was associated with systemic health. Most dentists were aware of a connection between periodontal disease and diabetes (84.4%) and heart disease (70.2%). Similarly, 85.6% believed in the negative impact of oral disease on the quality of life of patients. More female than male dentists were aware of the relationship between periodontal disease and adverse pregnancy outcomes, diabetes, and rheumatoid arthritis (P < 0.001). Most dentists (97%) believed that more patients would seek oral care if they were aware of the oral-systemic link. After adjustments, private dentists were 4.65 times more likely than public dentists to believe in improving access to oral care with increased patient awareness of the oral-systemic connection (P = 0.011).

    CONCLUSIONS: Most dentists were aware of the oral-systemic link. They believed that patients' access to oral care would improve if they were aware of a connection between oral and systemic health. Therefore, patients should be informed of the oral-systemic link to improve their oral health.

    Generally, industrial gas turbines (IGT) face transient behavior during start-up, load change, shutdown and variations in ambient conditions. These transient conditions shift engine thermal equilibrium from one steady state to another steady state. In turn, various aero-thermal and mechanical stresses are developed that are adverse for engine's reliability, availability, and overall health. The transient behavior needs to be accurately predicted since it is highly related to low cycle fatigue and early failures, especially in the hot regions of the gas turbine. In the present paper, several critical aspects related to transient behavior and its modeling are reviewed and studied from the point of view of identifying potential research gaps within the context of fault detection and diagnostics (FDD) under dynamic conditions. Among the considered topics are, (i) general transient regimes and pertinent model formulation techniques, (ii) control mechanism for part-load operation, (iii) developing a database of variable geometry inlet guide vanes (VIGVs) and variable bleed valves (VBVs) schedules along with selection framework, and (iv) data compilation of shaft's polar moment of inertia for different types of engine's configurations. This comprehensive literature document, considering all the aspects of transient behavior and its associated modeling techniques will serve as an anchor point for the future researchers, gas turbine operators and design engineers for effective prognostics, FDD and predictive condition monitoring for variable geometry IGT.

    Dentistry is a part of the field of medicine which is advocated in this digital revolution. The increasing trend in dentistry digitalization has led to the advancement in computer-derived data processing and manufacturing. This progress has been exponentially supported by the Internet of medical things (IoMT), big data and analytical algorithm, internet and communication technologies (ICT) including digital social media, augmented and virtual reality (AR and VR), and artificial intelligence (AI). The interplay between these sophisticated digital aspects has dramatically changed the healthcare and biomedical sectors, especially for dentistry. This myriad of applications of technologies will not only be able to streamline oral health care, facilitate workflow, increase oral health at a fraction of the current conventional cost, relieve dentist and dental auxiliary staff from routine and laborious tasks, but also ignite participatory in personalized oral health care. This narrative article review highlights recent dentistry digitalization encompassing technological advancement, limitations, challenges, and conceptual theoretical modern approaches in oral health prevention and care, particularly in ensuring the quality, efficiency, and strategic dental care in the modern era of dentistry.

    This study investigated the applications of recombinant monoclonal antibodies (rmAbs) produced against two recombinant filarial proteins of diagnostic value. Ab5B and Ab3A were produced against recombinant BmSXP, and Ab4 and Ab4-fragment crystallizable (Fc) against recombinant BmR1. Ab5B and Ab4-Fc were found to be useful as quality control (QC) reagents for two commercial rapid test kits, such as Brugia RapidTM and BLF Rapid® (Reszon Diagnostics International Sdn. Bhd., 47600 Subang Jaya, Selangor, Malaysia), respectively. The two rmAbs reacted positively with the corresponding recombinant proteins lined on the nitrocellulose strips of the cassette tests, thus may replace or reduce the need for patient serum samples as positive controls for QC of the commercial kits. They were also successfully conjugated to gold nanoparticles and reacted positively with the test lines containing the corresponding recombinant proteins when directly applied to the cassette tests. The gold-conjugated reagents can be used to confirm the antigenicity of test lines after the storage of the rapid tests for a prolonged period or under unfavorable conditions. Furthermore, Ab5B and Ab3A were shown to be able to capture the target recombinant proteins through immunoaffinity purification, enabling their use for applications that need very highly purified proteins. In conclusion, this study demonstrated several potential uses of rmAb proteins produced against recombinant filarial proteins.

    Purpose: To examine the relationship between sleeping quality and behavioural outcomes of UiTM Seremban 3 students.
    Methods and sample: A quantitative approach using a modified questionnaire of Pittsburgh Sleep Quality Index Score was employed to examine the sleeping quality and modified version of the Adolescent Behavioral Checklist was used to obtain the response on the behavioural of UiTM Seremban 3, students. 428 respondents from three (3) faculties in the Seremban campus
    participated in this study.
    Findings: The result shows that there is a significant relationship between sleeping quality and behavioural outcomes of the students (r=.118, p<0.05).
    Discussion and Conclusion: This study revealed that there is no significant relationship between sleeping quality and positive behavioural outcomes. However, the result indicated that there is a weak relationship between sleep quality and negative behavioural outcomes. The behaviours of the respondents tend to become
    more negative if they were having poor quality of sleep. The results also suggest that poor sleep quality is not only prevalent among college students but are also associated with negative behavioural outcomes. Therefore, sleeping quality should be considered in the management of students’ health and there is a need for an investigation for possible intervention on sleeping quality of the college students.

    Therapeutic drug monitoring (TDM) is a valuable clinical tool in optimisation of drug regimens. However, improper utilisation of TDM may lead to significant resource wastage and expose patients to avoidable trauma, toxicity, therapeutic failure and prolonged hospitalisation. This study aimed to reduce the percentage of inappropriate TDM sampling to our proposed standard of less than 20% within a four-month intervention period. A cross-sectional study was undertaken from January to December 2015 at the inpatient setting of Hospital Sultanah Nur Zahirah. Gentamicin and Vancomycin analytes were studied because these analytes accounted for 69.2% of total samples received in 2014. TDM Monitoring Form was used to collect sampling and dosage information to assess sampling appropriateness. A closed-ended self-administered questionnaire was distributed to a group of medical doctors to assess their knowledge on appropriate Gentamicin and Vancomycin TDM sampling method pre- and post-intervention. Prior to the intervention phase in October to December 2014, 79.4% of TDM were inappropriately sampled. The main contributing factors were inadequate knowledge among medical doctors, lack of sampling reminders for new TDM requests, and misunderstanding on sampling information for repeated TDM requests. 60-minute face-to-face educational sessions on TDM sampling method were conducted specifically for staff at the General Medical and Paediatric Departments, and two continuing medical education (CME) slots were held at the hospital level. Guidelines on TDM sampling was initiated and laminated copies were distributed to all wards. Implementation of TDM Alert System which consisted of digital reminders and physical stickers was also introduced. The interventions were able to reduce the inappropriate sampling percentage from 79.4% to 41.8% post-intervention, and to 19.1% in the recent monitoring phase of January until June 2019. Continuous close monitoring and sustainable implementation of the measures are vital as TDM sampling appropriateness may affect clinical interpretation of the results.

    The aim of this research is to explore the association between financial development, research and development (R&D) expenditures, globalization, institutional quality, and energy consumption in India by using the quarterly data of 1995-2018. Quantile Autoregressive Distributed Lag (QARDL) approach is employed to examine the relationship. An application of the QARDL approach suggests that the R&D, financial development, globalization, and institutional quality significantly influence energy utilization in India. R&D and institutional quality have a negative effect on energy utilization which shows that due to the increase in the quality of institutions and R&D in the country, energy utilization is likely to decrease. However, globalization and financial performance have a positive influence on energy which depicts that due to the increase in financial performance and globalization in India the energy consumption is likely to increase. According to the outcomes of this research, India should make a policy to ease the penalties of energy utilization by monitoring resource transfer by means of globalization and by implementing energy conversation procedures through the advancement of the financial sector.

    COVID-19 spread rapidly and jeopardised the physicians with not only treatment but also with limited resources and new working style. This study aimed to investigate the experience of physicians in Pakistan as frontline workers for the treatment of COVID-19 patients. The study employed a qualitative design and used Haas's adaptation of Colaizzi method for analysis. The respondents for the interview were selected based on purposive sampling and only those physicians were contacted who were treating COVID-19 patients in Lahore, Pakistan. The results of the study revealed many challenges faced by Pakistani physicians which included physical and psychological stress due to the treatment of COVID-19 patients. Moreover, infrastructural flaws have added in the vulnerabilities of the physicians. In developing countries, the fight is much harder for physicians as evidenced by their first-hand experience. The policymakers in developing countries especially in Pakistan can direct policies facilitating physicians to reduce their physical and psychological stress as well as increasing resources for the treatment of COVID-19 patients.

    Malaysia is one of the countries that is well known for its palm oil based products and exports all over the world. Over the years, palm oil mill has been rising at alarming rate in Malaysia, causing palm oil-based wastes to increase especially palm oil mill effluent (POME). POME in Malaysia are channelled into water bodies such as rivers after treated mostly with conventional biological method. However, with current technologies and knowledge, conventional POME treatments are seen to be outdated and require major improvements as greenhouse gaseous are emitted to the environment as well as being less cost effective. Integrated systems that combine two or more conventional methods are introduced and reviewed to provide insights on the advantages and disadvantages of the system if it is to be implemented in real life plant. Integrated systems that focus on combining conventional methods are compiled and reviewed specifically for POME treatment. Among the integrated methods that are reviewed includes biological with membrane, adsorption with magnetic field exposure, adsorption with membrane and electrocoagulation with membrane. The systems are seen to give excellent color, chemical oxygen demand (COD) and total suspended solids (TSS) removal with average of higher than 90%. Reduction in space utilization, improved treatment time as well as simplified operating system were reported when integrated systems are applied as compared to conventional treatment of POME.
