A new species of Metopeurum Mordvilko, 1914 (Hemiptera: Aphididae) from the Transcaucasus, with a key to the species of this genus.

The new aphid species Metopeurum caucasicum sp. nov. living on Achillea millefolium and five species of Tanacetum, namely T.

Olfactory function after mild traumatic brain injury in children-a longitudinal case control study.

The prevalence of posttraumatic olfactory dysfunction in children after mild traumatic brain injury ranges from 3 to 58%, with potential factors influencing this variation, including traumatic brain injury severity and assessment methods. This prospective longitudinal study examines the association between mild traumatic brain injury and olfactory dysfunction in children. Seventy-five pediatric patients with mild traumatic brain injury and an age-matched healthy control group were enrolled.

qU-Sniff - the development of a short version of the Universal "Sniffin' Sticks" test.

Objectives: Extensive olfactory testing is sparsely applied in pediatric patients in clinical routine especially because of its time taking nature. Therefore a 5-item odor identification test (quick "U-Sniff", "qU-Sniff") from the 12-item "U-Sniff" test was developed.

Methods: A total of 724 normosmic children between 6 and 17 years of age, divided in four age groups, were included in this retrospective study.

Complex evolution in Aphis gossypii group (Hemiptera: Aphididae), evidence of primary host shift and hybridization between sympatric species.

Aphids provide a good model system to understand the ecological speciation concept, since the majority of the species are host-specific, and they spend their entire lifecycle on certain groups of host plants. Aphid species that apparently have wide host plant ranges have often turned out to be complexes of host-specialized biotypes. Here we investigated the various host-associated populations of the two recently diverged species, Aphis gossypii and A.

Normative data for olfactory threshold and odor identification in children and adolescents.

Objective: Although previous studies have demonstrated the feasibility and validity of olfactory testing in children and adolescents using the "Sniffin' Sticks" odor threshold and "U-Sniff" odor identification test, normative data obtained in a large sample for these tests are missing. Aim of this study was therefore to obtain normative data of healthy children and adolescents for olfactory assessment.

Material And Methods: Olfactory testing was conducted using the "Sniffin' Sticks" olfactory threshold (THR) and the 12-item "U-Sniff" odor identification (ID) test.
