This leads to a possibility that boosting serotonin levels might have opposite effects on vigor to that seen when boosting dopamine levels. Here, we set out to test the effect on vigor of manipulating dopamine and serotonin in healthy human subjects. Participants were assigned to receive placebo, levodopa (150mg), or citalopram (24mg in oral drops, equivalent to 30mg in tablets) and performed the exact task described in our previous paper (Guitart-Masip et al, 2011) . The pharmacological agents are assumed to increase postsynaptic levels of dopamine and serotonin, respectively. We predicted that an increase in dopamine after levodopa administration would lead to a stronger modulation of the response times due to the influence of average reward rate. An additional possibility would be that an increase in serotonin after citalopram would weaken this modulation. METHODS Subjects 90 healthy volunteers were recruited for our pharmacological experiment (pharmacological subjects) using the subject pool associated with University College London's Psychology Department. A further 25 healthy volunteers were recruited for a control experiment (tired subjects). They received full written instructions, and provided written consent in accordance with the provisions of the University College London Research Ethics Committee. "Pharmacological" subjects Participants were randomly assigned to one of three treatment groups: 30 participants received levodopa (13 female; age range 17 years; mean 24.07, SD = 4.08 years), 30 participants received citalopram (17 female; age range 15 years; mean 23.6, SD = 4.2 years), and 30 participants received placebo (13 female; age range 11 years; mean 24.23, SD = 3.18 years). The study was double blind. All participants were right-handed and had normal or corrected-to-normal visual acuity. None of the participants reported a history of neurological, psychiatric or any other current medical problems.

INTRODUCTION Knowledge translation (KT) is a relatively new concept referring to transfers of knowledge into practice in collaboration with multiple sectors that work for the health and wellness of society. Knowledge translation is crucial to identifying and addressing the health needs of immigrants. AIM To scope the evidence on KT research engaging immigrants in the host country regarding the health and wellness of immigrants. METHODS This study followed a scoping review approach suggested by

We identified relevant studies from both academic and grey literature using structured criteria, charted the data from the selected studies, collated, summarised and report the results. RESULTS Analysis of the eligible studies found two types of KT research: integrated KT and end-of-grant KT. Meeting or discussion with community-level knowledge-users were common KT activities among immigrants, but they were involved in the entire research process only if they were hired as members of research teams. Most KT research among immigrants explored cancer screening and used a community-based participatory action research approach. Barriers and enablers usually came from researchers rather than from the community. There was little practice of evaluation and defined frameworks to conduct KT research among immigrants in Canada. CONCLUSION This study can help the researchers and other stakeholders of health and wellness of the immigrant population to identify appropriate KT research activities for immigrants and where KT research is required to facilitate the transfer of research knowledge into action.

How Dopamine Enhances an Optimism Bias in Humans

Tali Sharot, Marc Guitart-Masip, Christoph W. Korn, Rumana Chowdhury, Raymond J. Dolan
2012 Current Biology  
When predicting financial profits [1], relationship outcomes [2], longevity [3] , or professional success [4], people habitually underestimate the likelihood of future negative events (for review see [5] ). This well-known bias, termed unrealistic optimism [6], is observed across age [7], culture [8], and species [9] and has a significant societal impact on domains ranging from financial markets to health and well being. However, it is unknown how neuromodulatory systems impact on the
more » ... of optimistically biased beliefs. This question assumes great importance in light of evidence that common neuropsychiatric disorders, such as depression, are characterized by pessimism [10, 11] . Here, we show that administration of a drug that enhances dopaminergic function (dihydroxy-L-phenylalanine; L-DOPA) increases an optimism bias. This effect is due to L-DOPA impairing the ability to update belief in response to undesirable information about the future. These findings provide the first evidence that the neuromodulator dopamine impacts on belief formation by reducing negative expectations regarding the future.

Dopamine restores reward prediction errors in old age

2013 Nature Neuroscience  
Senescence affects the ability to utilize information about the likelihood of rewards for optimal decision-making. Using functional magnetic resonance imaging in humans, we found that healthy older adults had an abnormal signature of expected value, resulting in an incomplete reward prediction error (RPE) signal in the nucleus accumbens, a brain region that receives rich input projections from substantia nigra/ventral tegmental area (SN/VTA) dopaminergic neurons. Structural connectivity between
more » ... SN/VTA and striatum, measured by diffusion tensor imaging, was tightly coupled to inter-individual differences in the expression of this expected reward value signal. The dopamine precursor levodopa (L-DOPA) increased the task-based learning rate and task performance in some older adults to the level of young adults. This drug effect was linked to restoration of a canonical neural RPE. Our results identify a neurochemical signature underlying abnormal reward processing in older adults and indicate that this can be modulated by L-DOPA.

Intelligence quotient of the children was assessed by using Wechsler Intelligence Scale (WISC-R). Mean age of the epileptic children was 7.92 (±2.18) years while mean age of nonepileptic children was 7.95 (±2.17) years. Majority (61.8%) of the epileptic children was male and 38.2% was female, while among the non-epileptic children majority (58.2%) was female and 41.8% was male and the differences by sex was statistically significant [χ 2 (1) =4.4, P<0.05]. Among the epileptic children 47.3% lived in urban area while 76.4% non-epileptic lived in urban and this variation was statistically significant [χ 2 =11.31, P<0.01]. By education 45.5% of epileptic children were educated up to class 1-5 while most 80.0% of non-epileptic children were educated upto class 1-5 and this variation of education was statistically significant [χ 2 (4) =28.52, P<0.01]. According to family income Maximum (87.3%) of the epileptic children had monthly family income below Tk. 10,000 while 34.5% of the nonepileptic children had monthly family income Tk. >10,001 which was significantly associated with epilepsy [χ 2 (3) =3.79, P<0.01]. By place of delivery 45.5% epileptic children was delivered at home while maximum 52.7% non-epileptic children was delivered at private clinic and this variation was statistically significant [χ 2 (3) =26.43, P<0.01]. Majority (67.3%) of the epileptic children delivered normally while 56.4% non-epileptic children were delivered through caesarean section which was statistically significant [χ 2 (1) =6.22, P<0.01]. Majority 43.6% mothers of epileptic children faced long duration labor (10-14 hours) while 52.7% mothers of non-epileptic children faced short duration labor (2-5) hours which was statistically significant with epilepsy [χ 2 (2) =16.111, P<0.001]. Majority 63.6% of the epileptic children faced convulsion during early neonatal period and majority (70.9%) of non-epileptic children did not face any problem during early neonatal period. Intelligence quotient of the majority (60.0%) of the epileptic children were below normal (moron) while majority (76.4%) of the non-epileptic children were found normal which was statistically significant [χ 2 (7) =94.43, P<0.01]. In respect of clinical manifestation majority (65.5 %) of the epileptic children suffered from febrile convulsion and the main reason of epilepsy was birth trauma (43.6%). The study recommended for specific measure to raise intelligence quotient of epileptic children and to reduce the prevalence of epilepsy by overcoming the relevant risk factors in context of Bangladesh.

of the NIPPON DATA80/90 Research Group 8 Life expectancy (LE) is a measure that describes the health status of a population. The few published studies that have examined the impact of hypertension on LE were predominantly performed in Western populations. The effect of hypertension on LE has not been reported in an Asian population. Thus, we examined the impact of hypertension on LE in the Japanese population, which has the highest LE worldwide.

Age-specific mortality rates across different groups were estimated using the person-year method based on the follow-up data from a representative Japanese population in a national survey (NIPPON DATA80). The proportion of hypertensive patients in the baseline survey was 50.5% for men and 41.4% for women. The LE of 40-year-old men and women was 41.7 years and 48.7 years, respectively, in normotensive participants and 39.5 and 45.8 years, respectively, in hypertensive participants. The LE difference between normotensive and hypertensive participants was 2.2 years for men and 2.9 years for women. LE decreased with increasing stages of hypertension. Similar patterns of LE, with respect to blood pressure (BP) status, were observed in all index ages and for both genders. At the population level, hypertension leads to decreased LE and affects both genders similarly. Our findings highlight the importance of preventing high BP and the consequences of hypertension in Japanese population. Hypertension Research (2012) 35, 954-958;

2009 Journal of Social Sciences (New York, N.Y.)  
Problem statement: Increasing growth of population and shortage of producing capacity in Bangladesh have caused serious unemployment crisis and has forced the authorities to look for ways to reduce unemployment rate. Due to difference of structure and technology used in economic sectors and activities, the effects of factors on employment are different. So, for the purpose of findings alternatives to reduce unemployment rate in Bangladesh, it is necessary to estimate employment functions in all

Approach: In this study an attempt had been made to estimate short-run employment functions in manufacturing industries of Bangladesh, which are one of the most important sectors that has formed meaningful percent of country employment and gross national production. Adjustment of employment to its desired level and short run returns to employment had been explored in this study. Results: The model type I in comparison to the model type II of the relationship between value added and employment, which had been found to fit quiet well in Bangladesh manufacturing industries. The results showed that 1% increase in gross value added leads to 0.379% increase in employment. The coefficient of lagged employment is positive, indicated that the level of previous years employment increases the present year employment. Conclusion: The result also showed that the employment is negatively related to the real wage rate and the elasticity of employment with respect to real wage is about -0.251. The growth rate of value added exceeded the growth rate of employment in manufacturing industries in Bangladesh.

2015 BMC Women's Health  
Maternal anaemia is a common problem in pregnancy, particularly in developing countries. The study was aimed at determining the factors associated with anaemia among a group of pregnant mothers who attended an antenatal clinic in Dhaka city. Methods: This cross-sectional study included 224 pregnant women, who visited the antenatal clinic of the Marie Stops, Dhaka. Demographic data and information on maternal age, gestational age, educational and income level, and socioeconomic status were

The reference values of haemoglobin were categorized according to the World Health Organization (WHO) criteria as follows: normal (11 g/dL or higher), mild (10-10.9 g/dL), and moderate (7-9.9 g/dL). Mild and moderate levels of haemoglobin were defined as anaemic (haemoglobin levels of <11 g/dL). The SPSS software (Windows version 16.0. SPSS Inc, Chicago, USA) was used for analyzing data. Results: The mean (±SD) age of the subjects was 26.4 ± 2.81 years. Sixty-three percent of the subjects had normal level of haemoglobin, and 37 % were anaemic 26 % mild and 11 % moderate. Maternal anaemia was significantly associated with age (p = 0.036), education (p = 0.002), income (p = 0.001), living area (p = 0.031). Results of binary logistic regression analysis showed that maternal anaemia was also significantly associated with age (p = 0.006), educational status (primary to 8th grade, p = 0.004; secondary and above, p = 0.002), living area (0.022), and income (0.021). Discussion: A significant proportion of pregnant women were found anaemic. Most data showed education has animpact on awareness to use of health services and iron supplementation should be encouraged to improve the haemoglobin levels in pregnancy. Conclusions: The results indicate that anaemia is alarmingly high among pregnant women in Dhaka city. Maternal anaemia is associated with age, education level, income level, and living area. The results suggest that pregnant women and members of their families should be urgently educated to understand the importance of antenatal care.
