THE PREVALENCE OF BRUCELLOSIS IN CATTLE AND THEIR HANDLERS IN NORTH TONGU DISTRICT OF VOLTA REGION, GHANA
Background: Brucellosis is a zoonotic pathogen responsible for great economic losses in most sub-Saharan nations. Although
Ghana has successfully implemented the “One Health” initiative for the control of some emerging infectious zoonotic diseases with
pandemic potential like Avian Influenza, there is very limited data available on brucellosis especially human brucellosis prevalence.
He objective of his study is to determine the seroprevalence of human and bovine brucellosis as well as the predisposing factors at
the community level in the North Tongu District of Ghana.
Materials and Methods: Rose Bengal Plate test (RBPT) was used to analyze blood samples from 178 cattle farmers, and 315 cattle.
The positive samples were further confirmed with cELISA. Predisposing factors were determined by questionnaires administered to
cattle farmers. All sample sites were geo-referenced.
Results: Human and bovine brucellosis seroprevalence using RBPT were 10.1% and 22.9% respectively. Eighty six percent (62/72)
of bovine cases were confirmed with ELISA. Delivery assistants were more likely to be infected (p=0.043) with odds ratio of 2.7.
Out of the human cases (18), males constituted 88.9%. Ages 11-20 years recorded 77.7% seropositivity whilst cattle drovers
represented 44.5% (8/18) of positives. Significant risk factors in cattle were herd size (p=0.037), history of retained placenta (0.000)
and abortion (0.005).
Conclusion: Bovine and human brucellosis is prevalent in North Tongu district, Ghana. Close contact with parturient cows was a
major predisposing factor for human infection. Early referral of positive persons to the Hospital for confirmation and treatment is
required to comply with the “One Health” initiative on brucellosis and other zoonoses
Tetrahydropyrazolo[1,5-a]Pyrimidine-3-Carboxamide and N-Benzyl-6′,7′-Dihydrospiro[Piperidine-4,4′-Thieno[3,2-c]Pyran] analogues with bactericidal efficacy against Mycobacterium tuberculosis targeting MmpL3
Mycobacterium tuberculosis is a major human pathogen and the causative agent for the pulmonary disease, tuberculosis (TB). Current treatment programs to combat TB are under threat due to the emergence of multi-drug and extensively-drug resistant TB. As part of our efforts towards the discovery of new anti-tubercular leads, a number of potent tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide(THPP) and N-benzyl-6′,7′-dihydrospiro[piperidine-4,4′-thieno[3,2-c]pyran](Spiro) analogues were recently identified against Mycobacterium tuberculosis and Mycobacterium bovis BCG through a high-throughput whole-cell screening campaign. Herein, we describe the attractive in vitro and in vivo anti-tubercular profiles of both lead series. The generation of M. tuberculosis spontaneous mutants and subsequent whole genome sequencing of several resistant mutants identified single mutations in the essential mmpL3 gene. This ‘genetic phenotype’ was further confirmed by a ‘chemical phenotype’, whereby M. bovis BCG treated with both the THPP and Spiro series resulted in the accumulation of trehalose monomycolate. In vivo efficacy evaluation of two optimized THPP and Spiro leads showed how the compounds were able to reduce >2 logs bacterial cfu counts in the lungs of infected mice
A cross-national mixed-method study of reality pedagogy
This mixed-methods cross-national study investigated the effectiveness of reality pedagogy (an approach in which teachers become part of students’ activities, practices and rituals) in terms of changes in student perceptions of their learning environment and attitudes towards science. A questionnaire was administered to 142 students in grades 8–10 in the Bronx, New York City and Dresden, Germany. The questionnaire combines learning environment scales from the Constructivist Learning Environment Survey and the What Is Happening In this Class? Questionnaire with attitude scales from the Test of Science-Related Attitudes. Student interviews were used to support questionnaire findings. Quantitative data analyses revealed that reality pedagogy had a greater impact on students in the Bronx than in Dresden, with qualitative data clarifying differences in how reality pedagogy was enacted in each geographic area. Overall, our findings add to the body of evidence concerning the effectiveness of reality pedagogy as an approach to teaching and learning science across a variety of contexts. © 2016 Springer Science+Business Media Dordrech
Consumer-Based Leisure Constraint for Online Gaming
[[abstract]]The purpose of this study is to develop a multidimensional measure of consumer-based leisure constraint for online game play and to assess its psychometric properties. An empirical model of player constraint in online games provides the foundation to understanding and assessing how players differ from one another (such as high gamers/low gamers and high gamers/non-gamers) and how constraints on play relate to frequency of use. In the current study, an exploratory factor analysis was used to extract the common factors, and confirmatory factor analysis was used to create an empirical model of players' perception of constraint and to reveal its underlying structure. The analysis revealed six dimensions of constraint. The relationship between perception of constraint and frequency of use is also presented.[[notice]]補正完畢[[incitationindex]]SSCI[[booktype]]電子版[[booktype]]紙

Specific pain complaints in Iraq and Afghanistan veterans screening positive for post-traumatic stress disorder.
BackgroundPost-traumatic stress disorder (PTSD) and pain are highly comorbid.ObjectiveThe purpose of this study was to examine the association of PTSD with specific pain complaints in veterans of Operations Enduring and Iraqi Freedom (OEF/OIF).MethodA total of 381 primarily male (88.5%) veterans with a mean age of 30 years completed a battery of self-report questionnaires. A positive PTSD screen was defined as a score of ≥40 on the Davidson Trauma Scale. Logistic regression was used to examine the association of positive PTSD screen with specific pain complaints.ResultsThere were no significant demographic or physical and mental health differences between veterans who screened positive for PTSD only and those with PTSD and at least one pain complaint, although differences on rates of combat injury and depression approached significance. Veterans who screened positive for PTSD were 2 to 3 times more likely to report abdominal pain, muscle aches or cramps, and joint aches, even after controlling for age, gender, combat injury, and depression.ConclusionsSimilar to findings in other populations, there is a relationship between PTSD and pain complaints in OEF/OIF veterans. Future research should examine the mechanisms that link PTSD with specific pain complaints, especially abdominal pain
