    The primary reasons for myocardial infarction (MI) are pericarditis, arrhythmia, and heart failure, causing predominant deaths worldwide. Patients need a potential diagnostic system and treatment before cardiomyocyte damage. Cardiac biomarkers are released from myocytes immediately after a heart attack. Troponin is an efficient biomarker released from dead cells within a few hours. Aptamers are artificial antibodies used effectively in the biosensor field for biomarker detection. Along with aptamers, the application of nanomaterials is also expected to enhance the detection limits of biosensors. In this investigation, selected aptamers against cardiac troponin I (cTnI) were conjugated with gold nanoparticles (GNPs) to diagnose MI and compared with an aptamer-only control group on an interdigitated electrode surface. Based on electroanalysis, cTnI was detected at concentrations as low as 1 fM, and the detection limit improved to 100 aM when the aptamer was conjugated with GNP. In addition, aptamer-GNP conjugates increased the current level at the tested concentrations of cTnI. Control experiments with noncomplementary aptamers and relevant proteins did not result in notable changes in the current, demonstrating the selective detection of cTnI.

    Objective: This interventional study was aimed to investigate the effects of dark chocolate
    consumption on anxiety, depression, and stress (ADS) among trainee nurses. Methods: A
    parallel and open-label experimental study was conducted. Of the 128 nurses enrolled, only 47 participated in the intervention study (mean age = 20.32 years; ranging from 19 to 22 years old). They were randomly assigned to an intervention group (IG, n = 25) or a control group (CG, n = 22). The IG consumed dark chocolate and CG ingested mineral water for 3 consecutive days. The validated Malay Hospital Anxiety and Depression Scale (HADS) and Depression, Anxiety and Stress Scale (DASS-21) were utilised for measuring ADS levels. Data were analysed descriptively and score comparisons were conducted using non-parametric tests. Results: No significant differences between IG and CG in ADS scores were detected at baseline (all p > 0.05). At post-consumption, ADS score were significantly reduced in IG (all p < 0.01) compared with CG (all p < 0.05). Larger effect sizes among these respondents had also revealed that there were mood-elevating effects of dark chocolate consumption. Conclusion: This study has discovered that 3-day consumption of dark chocolate may alleviate ADS status among trainee nurses suggesting that dark chocolate may have a more prominent role in improving emotional and mood generally. Further investigations are however warranted to confirm this finding.

    Introduction: To date, there are limited published literatures addressing behaviors of Attention Deficit and Hyperactive Disorder (ADHD) children and their parents’ psychological
    characteristics. It is also crucial to know the relationship between characteristics of ADHD
    behaviors on their parental psychological impacts. Objective: To determine the level of stress, anxiety and depressive among mothers of ADHD children compared to control group and also to determine the associations between domains of children’s behaviors (externalizing or internalizing) that gives most impact to these maternal psychological aspects. Method: This is a cross-sectional study. Seventy mothers of ADHD children who came to Child and Adolescent Clinic, Universiti Kebangsaan Malaysia Hospital completed self-rating questionnaires of Child Behavior Checklist (CBCL), Parenting Stress Index (PSI) and Hospital Anxiety and Depressive Scale (HADS). Seventy mothers of asthmatic children were recruited as a control group. Results: Mothers with ADHD children are more anxious, depressed and stressed (p

    Objective: The purpose of this study was to evaluate the effectiveness of nutrition education intervention among university students in terms of social, psychological factors and nutrition-related Quality of Life (NQoL) outcomes after receiving a 10-week nutrition education. Longitudinal and randomised study design was adopted for the study. Methods: A total of 417 respondents from four public universities in Terengganu were randomly assigned to either intervention group (IG = 205) or control group (CG = 212). The IG received nutrition education through three tools; 1) conventional lecture, 2) brochures and 3) text messages via short messaging system (SMS) while the CG not received any intervention. Students completed the Malay version of NQoL (6 domains; 49 items; Likert-type responses=1-5) and SF-36 (8 domains; 36 items) at pre-intervention and post-intervention. Data analysis was carried out by using SPSS 16.0 utilising descriptive and parametric statistics. Results: Ninety-one percent of participants (IG = 178; CG = 202) completed the study (age = 19.1±1.1 years; female = 87.6%; Malay = 98.2%). After controlling for possible confounders (eg. weight, waist, hip circumferences and pre-intervention scores for each domain), IG possessed relatively higher NQoL score in Food Impact (p = 0.001), Social / Interpersonal (p = 0.008), Physical Functioning (p = 0.011) and Overall NQoL (p = 0.001). However, Psychological Factors did not show any significant difference for both groups. Conclusion: Although the intervention did not generate significant impact in the psychological component over a period of 10 weeks, significant positive impacts in Social/Interpersonal aspects and NQoL were clearly shown.

    Objectives: This study aims to determine the prevalence and associated factors of sexual pain disorders among Malay women in Malaysia with type 2 diabetes mellitus.
    Methods: This is a cross-sectional study involving 347 women (174 non- diabetic and 173 diabetic subjects) who attended the diabetic clinic in a university hospital. Sexual pain disorders were assessed using the Pain sub scale of Malay Version of the Female Sexual Function Index (MVFSFI). Socio-demographic information of the subjects was collected with a pre-designed questionnaire.
    Results: Prevalence of sexual pain disorders among Malay women with type 2 diabetes mellitus was 10.4% and the control group was 9.2% but the difference was not statistically significant (p > 0.05). Multivariate logistic regression analysis did not find any relevant associated factor with sexual pain disorder.
    Conclusion: Sexual pain disorders among Malay women were not dependent on the diabetic status. Further studies with different population of diabetic patients are needed to confirm the results.

    Objective: The objective of this study to assess the comparative effectiveness of exposure and response prevention (GERP) and cognitive-behaviour therapy (GCBT) in a group of Iranian patients with obsessive-compulsive disorder (OCD) and comorbid depression symptoms (CDS).

    Methods: Ninety OCD patients were selected (both genders, married or unmarried and ages from 18-65 years) using a non-probability sampling (availability sampling) procedure. The respondents subsequently sampled via cluster randomization into three equal groups: a control group (n = 30) that did not receive any treatment intervention during the study and two other groups who received 12 weeks of psychotherapy in the form of GERP (n=30) or GCBT (n=30). This study obtained the required data through a clinical interview with all participants based on the diagnostic and statistical manual of mental disorders text revision (DSM-IV-TR). The statistical analysis was performed using analysis of variance (ANOVA), Bonferroni correction and Pearson correlations.

    Result: We found that GCBT and GERP are effective treatments for alleviating OCD symptoms among patients. The results demonstrated that OCD scores were significantly reduced among participants after receiving GCBT and GERP treatments, with mean (standard deviation, SD) changes of 0.829 (0.287) and 0.970 (0.258), respectively. The study measured CDS through the Persian-language version of the Beck Depression Inventory-II (BDI-II-PERSIAN). The study further found a significant correlation between OCD and CDS. The findings suggested that GCBT and GERP improved comorbid depression symptoms (CDS) significantly with mean (SD) changes of 13.57 (3.92) and 12.85 (4.50) respectively.

    Conclusion: GCBT and GERP separately produced equivalent improvements for OCD and CDS.

    A study was undertaken to estimate the histological changes of gingival enlargement induced by
    Cyclosporin A (CsA) and Nifedipine, separately and in combination. Twelve adult rabbits were divided equally into four main groups. The first group received 10 mg/kg/day Nifedipine, the second received 10 mg/kg/day CsA, and the third received a combination of 10 mg/kg /day Nifedipine and CsA by gastric feeding. The fourth was regarded as a control group. Animals were given the drugs from day 1 of the experiment until day 70. They were then sacrificed for histological purposes. Results showed increase in the thickness of the epithelium with keratosis and acanthosis, and also increased vascularity. Collagen fibres and fibroblasts at different rates in the three histological groups were observed. Significant alveolar bone resorption with increased marrow spaces filled with fatty tissue were found in the CsA group. Non-significant changes in the alveolar bone of the Nifedipine group while subsequent bone resorption and bone deposition were seen in the combination group. These changes could be due to the effect of both drugs. Significant changes in the gingiva and the alveolar bone were shown in the three experimental groups compared with the control group.

    Objective: This study aimed to compare the difference in marginal dye penetration between everStick, Parapost XP, Parapost fiber white and control groups under gradual loading.

    Materials and Methods: Sixty-eight human maxillary permanent incisors were divided into four groups. Each specimen was endodontically treated with step-back technique and prepared for each post system according to experimental groups, subsequently cemented in the canal. Composite resin cores were built and laboratory fabricated metal crowns were cemented. All specimens except those in the control group were subjected to thermal cycling. All groups were subjected to gradual loading from 0N-50N for 100 cycles. Specimens were sectioned transversely and the depths of dye penetration along the post were measured. Data were entered in SPSS ver. 22 and analyzed using two-way ANOVA test.

    Results: There was no significant difference in marginal dye penetration between each group (p-value>0.05). However, there was a significant difference in percentage of marginal dye penetration between all groups (p-value<0.05); post-hoc comparison showed significant difference between Fiber White and Control groups (p-value=0.009).

    Conclusion: All the groups showed dye penetration but the percentage was significant only between Parapost Fiber White and the control groups.

    BACKGROUND AND OBJECTIVES: Modulation of the immune reaction is essential in the development of various diseases, including dengue's "Cytokine Tsunami", an increase in vascular permeability with concomitant severe vascular leakage. We aim to identify the role of T-helper (Th) cells, Th2 and Th7, with their related cytokines in dengue pathogenesis.

    MATERIAL AND METHODS: Nine electronic databases and manual search were applied to detect available publications. A meta-analysis using a fixed- or random-effect model was performed to measure standardized mean difference (SMD) with 95% confidence interval (CI). The National Institute of Health (NIH) tools for observational cohort, cross-sectional, and case-control studies were used to examine the risk of bias. The protocol was recorded in PROSPERO with CRD42017060230.

    RESULTS: A total of 38 articles were found including 19 case-control, 11 cross-sectional and 8 prospective cohort studies. We indicated that Th2 cytokines (IL-4, IL-6, IL-8) and Th17 cytokine (IL-17) in dengue patients were notably higher than in a healthy control group in acute phase (SMD = 1.59, 95% CI [0.68, 2.51], p = 0.001; SMD = 1.24, 95% CI [0.41, 2.06], p = 0.003; SMD = 1.13, 95% CI [0.61, 1.66], p<0.0001; SMD = 1.74, 95% CI [0.87, 2.61], p<0.0001), respectively.

    CONCLUSIONS: This study provides evidence of the significant roles of IL-4, IL-6, IL-8, IL-10 and IL-17 in the pathogenesis of developing a severe reaction in dengue fever. However, to fully determine the association of Th cytokines with dengue, it is necessary to perform further studies to assess kinetic levels during the duration of the illness.

    BACKGROUND: Oral lichen planus (OLP) is a common chronic mucocutaneous disease mostly seen in middle aged and elderly females. Oral lichen planus can occur in different oral sites such as gingiva, labial, buccal mucosa and on the tongue. And can have an indirect effect on initiating periodontitis.
    OBJECTIVES: The purpose of the study was to evaluate the periodontal status of OLP patients and compare it with that of healthy controls. The presence of erosive lesions among gingival tissues makes oral hygiene procedures difficult to perform for obvious reasons. Plaque control and rigorous oral hygiene are primary requisites for the treatment of any oro-mucosal disease.
    MATERIAL AND METHODS: Thirty patients with the erosive and reticular form of OLP as a study group and 30 healthy subjects as a control group were selected. The periodontal status of all subjects including gingival index (GI), Russell's periodontal index (PI) and bleeding on probing (BOP) were evaluated in both groups. Finally, the data was analyzed by a paired t-test using SPSS software v. 22.
    RESULTS: The mean values of GI, PI and BOP were observed to be higher in the study group compared to the control group, and this was statistically significant (p < 0.05). The results shown are suggestive that periodontal status was poor in the study group as compared to the control group.
    CONCLUSIONS: Further studies need to investigate periodontal status in oral lichen planus patients with larger sample size, and careful follow-up of these will assure an increase in the quality of life of these patients. The patient should be informed regarding the risk of periodontal problems in OLP and should be advised to have regular dental checkups to avoid a worsening of the conditio.

    Prostate cancer is the most common cancer type in men and is the second cause of death, due to cancer, in patients over 50, after lung cancer. Prostate specific antigen (PSA) is a widely used tumor marker for prostate cancer. Recently, PSA is discovered in non-prostatic cancer tissues in men and women raising doubts about its specificity for prostatic tissues. PSA exists in low serum level in healthy men and in higher levels in many prostate disorders, including prostatitis and prostate cancer. Thus, a supplementary tumor marker is needed to accurately diagnose the cancer and to observe the patient after treatment. Recently, soluble human leukocyte antigen-G (sHLA-G) has been introduced as a new tumor marker for different cancer types, including colorectal, breast, lung, and ovary. The present descriptive-experimental study was carried out including patients with malignant prostate tumor, patients with benign prostate tumor, and a group of health men as the control group, as judged by an oncologist as well as a pathologist. After sterile blood sampling, sHLA-G was measured by enzyme-linked immunosorbent assay in each group. The data was then analyzed using one-way ANOVA. P≤0.05 was considered as statistically significant. The results showed that the mean of sHLA-G level was high in patients. Also, it was found that there was a significant difference in sHLA serum level between the three groups. The data revealed that sHLA-G can be a novel supplementary tumor marker in addition to PSA to diagnose prostate cancer.

    Cannibalism is a major problem in lobster and crab aquaculture. Reducing the aggressive characteristics of lobsters and crabs can improve survival during the culturing process. In this study, juvenile scalloped spiny lobsters (Panulirus homarus) and crucifix crabs (Charybdis feriatus) were both cultured under different shelter and live prey conditions. Groups with shelter (seaweed and cotton filter) showed a better survival rate than the control group (no shelter; p < 0.05) for both Pa. homarus and Char. feriatus. Co-culturing with live prey (Litopenaeus vannamei) significantly benefited the juveniles of Pa. homarus and visibly increased the survival of juvenile Char. feriatus. Although providing shelter is currently the main method for reducing agonistic behavior, it must be continually altered as the lobsters and crabs grow. Live prey can grow and attract lobsters and crabs to hunt them, and live prey can be supplemented at any time. They can also be used as an additional source of income during the harvest season.

    The aim of this study was to determine the effectiveness of demineralized freeze-dried bone xenograft (DFDBBX) in minimizing post-surgical recession in moderate to advanced adult periodontitis in patients. Nine patients with a total of eighteen intrabony defects were matched for the tooth type, location of defects and periodontal pocket depth (5 to 7mm). Following an initial nonsurgical treatment, recession at defects indicated for surgery was measured pre-operatively. Surgical treatment was carried out by split mouth design, where the test sites were assigned DFDBBX and the control sites were subjected to debridement without the use of DFDBBX. Recessions were measured at 3 months, 6 months and 9 months post-operatively. The results showed no statistically significant difference in mean recession at 3, 6 and 9 months post-operatively compared to baseline for both test and control groups. Thus, DFDBBX was ineffective in minimizing recession on patients with moderate to severe periodontitis, as compared to surgical debridement alone.

    This study evaluated the effectiveness of demineralized freeze-dried bone xenograft in reducing post-surgical pocket depth in moderate to advanced adult periodontitis in patients. Nine patients with a total of eighteen intrabony defects were selected for this study. The bony defects were matched for tooth type, location and pocket depth. Following an initial non-surgical treatment, only pockets of 5 to 7 mm deep were indicated for surgery. Periodontal pockets were measured pre-operatively and at 3, 6 and 9 months post-surgically. The study protocol included a split mouth design, where surgical treatment was carried out at both test and control sites. The test sites were assigned demineralized freeze-dried bone xenograft and the control sites were subjected to debridement alone without the use of demineralized freeze-dried bone xenograft. The results from this study showed a statistically significant difference in the mean pocket depth at 6 and 9 months post-operatively for both test and control groups, but there was no statistically significant difference at 3 months. In conclusion, demineralized freeze-dried bone xenograft was ineffective in reducing periodontal pocket depth in patients with moderate to severe periodontitis, as compared to surgical debridement alone.

    The aim of this study was to assess the wear of tungsten carbide burs and round rotary diamond instruments through measurements of rake angle and visual observations respectively under a field emission scanning electron microscope. Sixty short and long head pear-shaped tungsten carbide burs and 18 round rotary diamond instruments that had been used to complete < 5, > 5 and > 10 cavity preparations (n=10/group) were selected from the 3rd and 4th year dental students, Faculty of Dentistry, University of Malaya. There were two control groups consisting of long and short tungsten carbide burs of ten each. Two-way ANOVA was used to analyse the rake angle data. The data from the two control groups were collectively analysed following multiple paired t-test (p>.05) which showed no significant difference between the two types of tungsten carbide bur (short and long head). The mean rake angle of the control group was significantly higher (p < .05) compared to the < 5, > 5 and > 10 cavity preparation groups. The rake angle of the > 10 cavity preparation group was significantly lower than the other two test groups (p < .05). Round rotary diamond instruments in the < 5 cavity preparation group showed intact diamond particles with distinct cutting facets comparable to the control group. However, diamonds instruments in the > 5 and > 10 cavity preparation groups showed blunt diamond particles. In conclusion, wear of tungsten carbide burs and round rotary diamond instruments were evident after repeated use. Wear was more pronounced when instruments were used to prepare more than ten cavities.

    Endodontically treated teeth are generally weaker than sound teeth. The study objective was to compare the fracture resistance of endodontically treated teeth restored with different restorative techniques. Fifty extracted human maxillary central incisors of similar size were divided into five groups of 10 teeth. Group 1 was left intact as the control group. Other groups (Groups 2, 3, 4 and 5) were all endodontically treated followed by restorations using different restorative techniques; light cured composite resin (CR), CR and crown, post and CR, and post-CR core and crown respectively. The specimens were loaded in a universal testing machine with a static force at a crosshead speed of 0.5mm/min at 135 ° to the long axis of the root until failure. The means and the standard deviations of the maximum load at failure for groups 1, 2, 3, 4 and 5 were 1259.11N (379.12N), 578.63N (196.70N), 667.13N (298.72N), 1247.65N (294.48N) and 623.60N (193.75N) respectively.

    Some of the beneficial bio compatible properties of hydroxyapatite [Ca10(PO4)6(OH)2]; the major componentand an essential ingredient of normal bone and teeth, are that it is rapidly integrated into the human body and will bondto bone forming in distinguishable unions. But, before new materials are approved for medical use, mutagenesis systems to exclude cytotoxic, mutagenic or carcinogenic properties are applied worldwide. This study aimed to detectany chromosomal aberrations induced by the synthetic hydroxyapatite granules [Manufactured by Universiti Sains
    Malaysia, (USM) Penang, Malaysia] in the bone marrow cells of mice. The mitotic indices of the groups treated with synthetic hydroxya patite granules did not show any significant difference as compared to the negative control group treated with distilled water. Also the groups of mice treated with synthetic hydroxyapatite granules and distilled waterdid not induce significant change in chromosome aberrations as compared to the positive control group treated with Mitomycin C. The mitotic indices and chromosomal analyses indicate that under the present test conditions, synthetichydroxya patite granules (manufactured by USM) are non cytotoxic and do not induce chromosome aberrations in the bone marrow cells of mice.

    INTRODUCTION: Captopril is an angiotensin-converting enzyme inhibitor, which is used as an antihypertensive agent and has shown antioxidant properties. This study aims at determining the effects of captopril on factors affecting gastric mucosal integrity in aspirin-induced gastric lesions.
    MATERIAL AND METHODS: Eighteen male Sprague-Dawley (200-250 g) rats that were given aspirin (40 mg/100 g body weight) were divided into three groups: the control, captopril (1 mg/100 g body weight daily) and ranitidine (2.5 mg/100 g body weight twice daily) groups. Ranitidine and captopril were given orally for 28 days. Rats in all groups were sacrificed and the parameters measured.
    RESULTS: Captopril reduced gastric acidity, and increased gastric glutathione (GSH) and prostaglandin E2 (PGE2) significantly in comparison to the control group. Captopril also reduced malondialdehyde (MDA) and gastric lesions insignificantly compared to the control group. Ranitidine healed the lesions significantly compared to the control group. There was no difference between ranitidine and captopril on the severity of lesions, gastric acidity, MDA and GSH. Captopril increased PGE2 compared to ranitidine (p < 0.05).
    CONCLUSIONS: Captopril has desirable effects on the factors affecting gastric mucosal integrity (acidity, PGE2 and GSH) and is comparable to ranitidine in ulcer healing.
