Three commonly encountered species, Heterolepidoderma ocellatum, Lepidochaetus zelinkai, and Lepidodermella squamata, are investigated for cryptic speciation. Most of the material is based on Swedish ACY-738 specimens but closely related species from other parts of the world are also included. Taxonomic revisions are supported by phylogenies based on 18S rRNA, 28S rRNA, and COI mtDNA of freshwater Chaetonotidae from several genera and inferred from Bayesian and maximum likelihood approaches. Heterolepidoderma ocellatum f. sphagnophilum is raised to species level, under the name H. acidophilum n. sp. Moreover, genetic data based on COI indicate large variation between two morphologically very similar

groups of Lepidodermella squamata. The extent of cryptic speciation in L. zelinkai appears low. Based on the phylogenetic hypothesis presented in this article, the P005091 molecular weight new species, Lepidodermella intermedia n. sp., from northern Sweden is also described. The phylogenetic hypothesis generated shows that Chaetonotidae

is a non-monophyletic group.”
“The aim of this study was to examine the relationships among physical self-perception, body image and motor performance in Italian middle school students. Two hundred and sixty children were categorized into normal-weight (n=103), overweight (n=86) or obese (n=71) groups. Perceived coordination, body fat and sports competence were assessed using the Physical Self-Description Questionnaire, while body image was measured using Collins’ Child Figure Drawings. Individuals’ perceptions of strength, speed and agility were assessed using the Perceived Physical Ability Scale. Tests involving the standing Mdm2 inhibitor long jump, 2 kg medicine-ball throw, 10 x 5 m shuttle-run and 20 and 30 m sprints were

also administered. Girls, when compared with boys, and overweight and obese participants, when compared with normal-weight peers, reported lower perceived and actual physical competence, higher perceived body fat and greater body dissatisfaction. Body dissatisfaction mediated all the associations between body mass index (BMI) and the different aspects of physical self-perception in boys, but not in girls. The same pattern of results was found for physical self-perception as a mediator of the relationship between BMI and body dissatisfaction. In conclusion, obesity proved to have adverse effects on both motor performance and physical self-perception.”
“PFEIFFER, B., T. STELLINGWERFF, E. ZALTAS, and A. E. JEUKENDRUP. CHO Oxidation from a CHO Gel Compared with a Drink during Exercise. Med. Sci. Sports Exerc., Vol. 42, No. 11, pp. 2038-2045, 2010. Recently, it has been shown that ingestion of solutions with glucose (GLU) and fructose (FRC) leads to 20%-50% higher CHO oxidation rates compared with GLU alone. Although most laboratory studies used solutions to deliver CHO, in practice, athletes often ingest CHO in the form of gels (semisolid).
