Development of Deep and Upper Neuronal Layers in the Domestic Cat, Sheep and Pig Neocortex.

The neocortex plays a key role in cognition, volitional motor control and sensory perception and has undergone tremendous expansion during evolution. The mature neocortex consists of radially aligned neurons that are arranged in six layers. Layers II-VI are often split into two groups: deep and upper layers, both building up the so-called cortical plate during embryonic and foetal development.

[Physiology and pathology of reproduction in domesticated New World camelids with special emphasis on ultrasonography].

The number of New World camelids in Germany is increasing. Owners and breeders are usually well educated regarding their animals. For practitioners, this means being up-to-date with respect to their veterinary knowledge.

Does lower extremity osteoarthritis exacerbate risk factors for falls in older adults?

The risk of falling reportedly increases almost 2.5-times in those with lower extremity osteoarthritis (OA(LE)) compared with age-matched controls. However, the mechanisms underlying the increased risk are not clear.

Age, sex, and finish time as determinants of pacing in the marathon.

Previous researchers have suggested that faster marathoners tend to run at a more consistent pace compared with slower runners. None has examined the influence of sex and age on pacing. Therefore, the purpose of this study was to determine the simultaneous influences of age, sex, and run time on marathon pacing.

Matrix isolation study of the early intermediates in the ozonolysis of cyclopentene and cyclopentadiene: observation of two Criegee intermediates.

Matrix isolation studies, combined with infrared spectroscopy, of the twin jet codeposition of ozone into matrices containing either cyclopentadiene or cyclopentene have led to the first observation of several early intermediates in these ozonolysis reactions. Specifically, evidence is presented for the formation, identification, and characterization of the long sought-after Criegee intermediate for each system, as well as the primary and secondary ozonides. These were observed after initial twin jet deposition and grew approximately 300% upon annealing to 35 K.
