Halkides, Christopher J. – Journal of Chemical Education, 2013
In this activity, students manipulate three-dimensional molecular models of the Ala-Ala-Ala tripeptide, where Ala is alanine. They rotate bonds to show that the pairs of dihedral angles phi = 0 degrees, psi = 180 degrees, and phi = 0 degrees, psi = 0 degrees lead to unfavorable interactions among the main chain atoms of the tripeptide. This…

Iriyama, Yae; Murayama, Nobuko – Health Education Journal, 2014
Objective: We conducted a randomized controlled crossover trial to evaluate the effects of a new worksite weight-control programme designed for men with or at risk of obesity using a combination of nutrition education and nutrition environmental interventions. Subjects and methods: Male workers with or at risk of obesity were recruited for this…

Farrell, John J. – Journal of Chemical Education, 1977
An integrated physical-analytical-inorganic chemistry laboratory procedure for use with undergraduate biology majors is described. The procedure requires five to six laboratory periods and includes acid-base standardizations, potentiometric determinations, computer usage, spectrophotometric determinations of crystal-field splitting…

Demirci, Nevzat – Educational Research and Reviews, 2015
This study was conducted in order to know the impact of coenzyme Q[subscript 10] (CoQ[subscript 10]) supplement on the muscle damage and total oxidant (TOS) enzyme levels of young skiing athletes during exercise. 15 male athletes were used for two weeks in the study. The athletes were divided into three groups: the control group and two subject…

Knechtle, Beat; Knechtle, Patrizia; Kaul, Rene; Kohler, Gotz – Research Quarterly for Exercise and Sport, 2009
We evaluated whether ultraendurance swimmers suffer a change of body mass, fat mass, skeletal muscle mass, total body water, and specific gravity of urine during a 12-hr swim in 12 male Caucasian ultraswimmers. Proton nuclear magnetic resonance of urine samples before and after the race was performed to detect alanine, lactate, and…

Filipek, Pauline A.; Juranek, Jenifer; Nguyen, Minh T.; Cummings, Christa; Gargus, J. Jay – Journal of Autism and Developmental Disorders, 2004
A random retrospective chart review was conducted to document serum carnitine levels on 100 children with autism. Concurrently drawn serum pyruvate, lactate, ammonia, and alanine levels were also available in many of these children. Values of free and total carnitine ([rho] less than 0.001), and pyruvate ([rho]=0.006) were significantly reduced…

Aldred, Sarah; Moore, Kieran M.; Fitzgerald, Michael; Waring, Rosemary H. – Journal of Autism and Developmental Disorders, 2003
Plasma amino acid levels were measured in autistic (n=12), Asperger syndrome (n=11) patients, their parents and siblings. Patients with autism or Asperger syndrome and their siblings and parents all had raised glutamic acid, phenyalanine, asparagine, tyrosine, alanine, and lysine levels than age-matched controls. Results suggest dysregulated amino…

Baxter, Amy L.; Lindberg, Daniel M.; Burke, Bonnie L.; Shults, Justine; Holmes, James F. – Child Abuse & Neglect: The International Journal, 2008
Objectives: Previous research in adult patients with blunt hepatic injuries has suggested a pattern of serum hepatic transaminase concentration decline. Evaluating this decline after pediatric blunt hepatic trauma could establish parameters for estimating the time of inflicted injuries. Deviation from a consistent transaminase resolution pattern…

Shemesh, Eyal; Annunziato, Rachel A.; Yehuda, Rachel; Shneider, Benjamin L.; Newcorn, Jeffrey H.; Hutson, Carolyn; Cohen, Judith A.; Briere, John; Gorman, Jack M.; Emre, Sukru – Journal of the American Academy of Child & Adolescent Psychiatry, 2007
Objective: The study assessed the relationship between a history of child abuse, nonadherence to medications, and medical outcome in children who had a liver transplant. Method: Abuse history for children and adolescents ages 8 to 21 who underwent a liver transplantation at Mount Sinai Medical Center in New York was obtained in interviews in 2002.…
