Relationship Between The Black Cocoa Ant, Dolichoderus Thoracicus Smith (Hymenoptera: Formicidae) and the Cocoa Pod Borer, Conopomorpha Cramerella Snellen(Lepidoptera: Gracillarlldae) in a Cocoa-Coconut Ecosystem

The relationship between the black cocoa ant Dolichoderus thoracicus Smith (Hymenoptera: Formicidae) and the cocoa pod borer Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) was studied in a cocoa-coconut field. D. thoracicus was present in moderate to high abundance in the field at the beginning of the experiments. In one treatment, the D. thoracicus population was depressed with insecticides (ant-scarce plots) and was augmented in the other treatment by the provision of artificial nests and dried leaf shelters (ant-abundant plots). percentage of C. cramere/la infestation in ant-abundant plots was generally less than 50% while the reverse was true in ant-scarce plots. Even though there was no significant difference in the percentage of pods which were infested and extractable as well as partially extractable, the percentage of unextractable pods in ant-abundant plots was significantly lower than in ant-scarce plots, indicating that D. thoracicus reduced the severity of C. cramerella infestation. This difference was evident throughout the trial. Mammalian damage was also more pronounced in ant-scarce plots. In a survey of the relationship between D. thoracicus pod abundance and C. cramerella infestation conducted within and outside the trial area, the two were found to be negatively related. Pods within the trial plots also had less C. cramerella damage compared to those outside the trial plots, indicating a possible attrition effect. Pods from which D. thoracicus were deliberately excluded also had a higher incidence of infestation compared to pods on which D. thoracicus was enhanced. Moderate D. thoracicus abundance on pods was sufficient to prevent C. cramerella infestation. The mechanism of control was probably deterrence of C. cramere/la oviposition. This study shows that encouraging D. thoracicus is beneficial to cocoa as it reduces the damage of two major pests, C. cramerella and mammals

Mindful gratitude journaling: psychological distress, quality of life and suffering in advanced cancer: a randomised controlled trial

Context Numerous studies have shown that gratitude can reduce stress and improve quality of life. Objective Our study aimed to examine the effect of mindful gratitude journaling on suffering, psychological distress and quality of life of patients with advanced cancer. Methods We conducted a parallel-group, blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Ninety-two adult patients with advanced cancer, and an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned to either a mindful gratitude journaling group (N=49) or a routine journaling group (N=43). Results After 1 week, there were significant reductions in the overall suffering score from the baseline in both the intervention group (mean difference in overall suffering score=−2.0, 95% CI=−2.7 to −1.4, t=−6.125, p=0.000) and the control group (mean difference in overall suffering score=−1.6, 95% CI=−2.3 to −0.8, t=−4.106, p=0.037). There were also significant improvements in the total Hospital Anxiety and Depression Scale score (mean difference=−3.4, 95% CI=−5.3 to −1.5, t=−3.525, p=0.000) and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (mean difference=7.3, 95% CI=1.5 to 13.1, t=2.460, p=0.014) in the intervention group after 7 days, but not in the control group. Conclusion The results provide evidence that 7 days of mindful gratitude journaling could positively affect the state of suffering, psychological distress and quality of life of patients with advanced cancer

The epidemiology and clinical characteristics of myeloproliferative neoplasms in Malaysia

Abstract Background The evolution of molecular studies in myeloproliferative neoplasms (MPN) has enlightened us the understanding of this complex disease consisting of polycythaemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). The epidemiology is well described in the western world but not in Asian countries like Malaysia. Materials and methods This retrospective national registry of MPN was conducted from year 2009 to 2015 in Malaysia. Results A total of 1010 patients were registered over a period of 5 years. The mean age was 54 years with male predominance. The ethnic distribution revealed that Chinese had a relatively high weighted incidence proportion (43.2%), followed by Indian (23.8%), Malay (15.8%) and other ethnic groups (17.2%). The types of MPN reported were 40.4% of ET (n = 408), 38.1% of PV (n = 385), 9.2% of PMF (n = 93), 3.1% of hypereosinophilic syndrome (HES) (n = 31) and 7.9% of unclassifiable MPN (MPN-U) (n = 80). Splenomegaly was only palpable clinically in 32.2% of patients. The positive JAK2 V617F mutation was present in 644 patients with 46.6% in PV, 36.0% in ET, 9.0% in PMF, and 7.4% in MPN-U, and had significantly lower haemoglobin (p < 0.001), haematocrit (p < 0.001) and white blood cells (WBC) (p < 0.001) than those with negative mutation. Significant differences in platelet and WBC count were detected in ethnic groups and MPN sub-types. There were more arterial thrombosis events seen in those with JAK2 V617F mutation as compared to venous thrombosis events (23.1% vs 4.4%). The bleeding rate was only 6.6%. Among the risk factors, previous thrombosis, old age (≥ 60 years) and hypertension were significantly correlated to positive JAK2 V617F mutation. The arterial thrombosis event is associated with higher presenting HB, HCT and PLT while the bleeding event is associated with lower presenting HB, HCT but higher PLT. The presence of JAK2 V617F mutation is associated with higher risk of arterial thrombosis. Conclusion Chinese ethnicity is associated with higher rates of MPN. The history of thrombosis, age ≥ 60 years and hypertension are risk factors that can be correlated to JAK2 V617F mutation. This study is instrumental for policy makers to ensure preventive strategies can be implemented in future

Perspectives on ENCODE

The Encylopedia of DNA Elements (ENCODE) Project launched in 2003 with the long-term goal of developing a comprehensive map of functional elements in the human genome. These included genes, biochemical regions associated with gene regulation (for example, transcription factor binding sites, open chromatin, and histone marks) and transcript isoforms. The marks serve as sites for candidate cis-regulatory elements (cCREs) that may serve functional roles in regulating gene expression1. The project has been extended to model organisms, particularly the mouse. In the third phase of ENCODE, nearly a million and more than 300,000 cCRE annotations have been generated for human and mouse, respectively, and these have provided a valuable resource for the scientific community.11Nsciescopu

Expanded encyclopaedias of DNA elements in the human and mouse genomes

AbstractThe human and mouse genomes contain instructions that specify RNAs and proteins and govern the timing, magnitude, and cellular context of their production. To better delineate these elements, phase III of the Encyclopedia of DNA Elements (ENCODE) Project has expanded analysis of the cell and tissue repertoires of RNA transcription, chromatin structure and modification, DNA methylation, chromatin looping, and occupancy by transcription factors and RNA-binding proteins. Here we summarize these efforts, which have produced 5,992 new experimental datasets, including systematic determinations across mouse fetal development. All data are available through the ENCODE data portal (https://www.encodeproject.org), including phase II ENCODE1 and Roadmap Epigenomics2 data. We have developed a registry of 926,535 human and 339,815 mouse candidate cis-regulatory elements, covering 7.9 and 3.4% of their respective genomes, by integrating selected datatypes associated with gene regulation, and constructed a web-based server (SCREEN; http://screen.encodeproject.org) to provide flexible, user-defined access to this resource. Collectively, the ENCODE data and registry provide an expansive resource for the scientific community to build a better understanding of the organization and function of the human and mouse genomes.11Nsciescopu
