Adolescent Physical Activity And Screen Time: Associations With The Physical Home Environment, John R. Sirard, Melissa N. Laska, Carrie D. Patnode, Kian Farbakhsh, Leslie A. Lytle 2009 University of Massachusetts - Amherst

Adolescent Physical Activity And Screen Time: Associations With The Physical Home Environment, John R. Sirard, Melissa N. Laska, Carrie D. Patnode, Kian Farbakhsh, Leslie A. Lytle

John Sirard

Background: Previous research on the environment and physical activity has mostly focused on macro-scale environments, such as the neighborhood environment. There has been a paucity of research on the role of microscale and proximal environments, such as that of the home which may be particularly relevant for younger adolescents who have more limited independence and mobility. The purpose of this study was to describe associations between the home environment and adolescent physical activity, sedentary time, and screen time. Methods: A total of 613 parent-adolescent dyads were included in these analyses from two ongoing cohort studies. Parents completed a Physical Activity ...

Neurodynamics Of An Election, Armando F. Rocha, Fabio T. Rocha, Marcelo N. Burattini, Eduardo Massad

Armando F Rocha

Variables influencing decision-making in real settings, as in the case of voting decisions, are uncontrollable and in many times even unknown to the experimenter. In this case, the experimenter has to study the intention to decide (vote) as close as possible in time to the moment of the real decision (election day). Here, we investigated the brain activity associated with the voting intention declared 1 week before the election day of the Brazilian Firearms Control Referendum about prohibiting the commerce of firearms. Two alliances arose in the Congress to run the campaigns for YES (for the prohibition of firearm commerce ...

Perinatal Exposure To Polychlorinated Biphenyls Alters Social Behaviors In Rats, Howard C. Cromwell 2009 Bowling Green State University

Perinatal Exposure To Polychlorinated Biphenyls Alters Social Behaviors In Rats, Howard C. Cromwell

Howard Casey Cromwell

Perinatal exposure to polychlorinated biphenyls (PCBs) leads to significant alterations of neural and hormonal systems. These alterations have been shown to impair motor and sensory development. Less is known about the influence of PCB exposure on developing emotional and motivational systems involved in social interactions and social learning. The present study examined the impact of perinatal PCB exposure (mixture of congeners 47 and 77) on social recognition in juvenile animals, conspecific-directed investigation in adults and on neural and hormonal systems involved in social functions. We used a standard habituation–dishabituation paradigm to evaluate juvenile recognition and a social port paradigm ...

A study published in Toxicological Sciences (Ryan et al., 2009) illustrates the importance of examining appropriate doses of both the positive control and the test chemical in research on endocrine-disrupting chemicals. For the three low doses of bisphenol A (BPA) that were fed to rats during pregnancy and lactation, there were no effects on female offspring (there were also no effects on male offspring from the same experiment; Howdeshell et al., 2008). A review of the results of the positive control doses makes it clear that the experiment cannot adequately assess the consequences of low-dose exposure to BPA because the ...


Assessing The Value Of Dna Barcodes And Other Priority Gene Regions For Molecular Phylogenetics Of Lepidoptera, John James Wilson 2009 University of Malaya

Assessing The Value Of Dna Barcodes And Other Priority Gene Regions For Molecular Phylogenetics Of Lepidoptera, John James Wilson

John James Wilson

Background: Despite apparently abundant amounts of observable variation and species diversity, the order Lepidoptera exhibits a morphological homogeneity that has provided only a limited number of taxonomic characters and led to widespread use of nucleotides for inferring relationships. This study aims to characterize and develop methods to quantify the value of priority gene regions designated for Lepidoptera molecular systematics. In particular, I assess how the DNA barcode segment of the mitochondrial COI gene performs across a broad temporal range given its number one position of priority, most sequenced status, and the conflicting opinions on its phylogenetic performance. Methodology/Principal Findings ...


Mining And Civilization, An Illustrated History, Fathi Habashi 2009 Laval University, Quebec City, Canada

Mining And Civilization, An Illustrated History, Fathi Habashi

Fathi Habashi

Mining and Civilization has been conceived to compliment the author's two books History of Metallurgy and Readings in Historical Metallurgy and to fill a gap in the literature. It is difficult to study the history of metallurgy without studying the history of mining at the same time. Each time the author visits ancient ruins or examines an ancient stone statue he recalls the work of miners who brought the material from a quarry so that the sculptor can create a work of art. History of mining, quarrying, and stone carving is history of civilization.

The Carboxyl-Terminal Segment Of Apolipoprotein A-V Undergoes A Lipid-Induced Conformational Change, Kasuen Mauldin, B. L. Lee, M. Oleszczuk, B. D. Sykes, R. O. Ryan 2009 University of California - Berkeley

The Carboxyl-Terminal Segment Of Apolipoprotein A-V Undergoes A Lipid-Induced Conformational Change, Kasuen Mauldin, B. L. Lee, M. Oleszczuk, B. D. Sykes, R. O. Ryan

Kasuen Mauldin

Apolipoprotein (apo) A-V is a 343-residue, multidomain protein that plays an important role in regulation of plasma triglyceride homeostasis. Primary sequence analysis revealed a unique tetraproline sequence (Pro293-Pro296) near the carboxyl terminus of the protein. A peptide corresponding to the 48-residue segment beyond the tetraproline motif was generated from a recombinant apoA-V precursor wherein Pro295 was replaced by Met. Cyanogen bromide cleavage of the precursor protein, followed by negative affinity chromatography, yielded a purified peptide. Nondenaturing polyacrylamide gel electrophoresis verified that apoA-V(296-343) solubilizes phospholipid vesicles, forming a relatively heterogeneous population of reconstituted high-density lipoprotein with Stokes’ diameters>17 nm ...

Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (PhD), Randy Adjonu, Justice Asomaning 2009 University of Alberta

Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (Phd), Randy Adjonu, Justice Asomaning

Professor Emmanuel Ohene Afoakwa

Investigations were conducted on the viscoelastic properties and pasting characteristics of fermented maize with malted cereals and their suitability for infant feeding. A 3x3x2 factorial experimental design with malting time, cereal malt concentration and cereal type was used. Maize, millet, and sorghum malts were added to fermented maize to reducing its bulk density. Samples were analysed for their viscoelastic properties and pasting characteristics using Brabender Viscoamylograph. Sorghum malt in comparison to millet and maize malts was not effective in terms of lowering the hot and cold paste viscosities of the fermented maize. Maize and millet malts liquefied the dough considerably ...


Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (PhD), Edem John Kongor, George Annor, Randy Adjonu 2009 University of Ghana

Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (Phd), Edem John Kongor, George Annor, Randy Adjonu

Professor Emmanuel Ohene Afoakwa

Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using Brabender Viscoamylograph. Fermentation caused significant variations in the pH, non-volatile acidity and starch concentration. The pH decreased with concomitant increases in non-volatile acidity during co-fermentation of the cassava dough. Soy-fortification upto 20% caused only minimal effects on the pH, titratable acidity and starch content during the fermentation period. Starch content decreased from 69.8%-60.4% within the 48 ...


Response Surface Methodology For Studying The Quality Characteristics Of Cowpea (Vigna Unguiculata)-Based Tempeh., George Amponsah Annor, Esther Sakyi-Dawson, Samuel Sefa-Dedeh, Firibu Kwesi Saalia, Dr. Emmanuel Ohene Afoakwa (PhD), Kwaku Tano-Debrah, Agnes Simpson Budu 2009 University of Guelph

Response Surface Methodology For Studying The Quality Characteristics Of Cowpea (Vigna Unguiculata)-Based Tempeh., George Amponsah Annor, Esther Sakyi-Dawson, Samuel Sefa-Dedeh, Firibu Kwesi Saalia, Dr. Emmanuel Ohene Afoakwa (Phd), Kwaku Tano-Debrah, Agnes Simpson Budu

Professor Emmanuel Ohene Afoakwa

Response surface methodology was used to optimize the processing conditions in the preparation of cowpea tempeh. The independent factors studied were boiling time (varying from 5 to 30 min), incubation time (varying from 12 to 48 h) and incubation temperatures (varying from 25 to 50°C), whereas the dependent factors were protein content, protein solubility, pH, titratable acidity and total color difference (using L, a* and b*). Regression models were generated and adequacy was tested with regression coefficients (R2) and the lack-of-fit tests. Optimum processing conditions were determined by method of superimposition. There was a strong and significant influence (P < 0.01) of the quadratic effect of the incubation time on the protein content of the cowpea tempeh, with similar significance (P < 0.01) noted in protein solubility with increasing boiling time. The optimum processing conditions observed for the preparation of cowpea tempeh were boiling time of about 20 min, incubation time of about 28 h and incubation temperature of about 37°C.
