Males of all reed frog species (Anura: Hyperoliidae) have a prominent, often colourful, gular patch on their vocal sac, which is particularly conspicuous once the vocal sac is inflated. Although the presence, shape, and form of the gular patch are well-known diagnostic characters for these frogs, its function remains unknown. By integrating biochemical and(More)
In a review of the literature the current knowledge of the diagnostic significance of sialic acid (NANA), neuron-specific enolase (NSE) and carcinoembryonic antigen (CEA) in the detection and differentiation of brain tumors is demonstrated. The efficiency of some additional biochemical tumor markers is briefly described. In a total of 101 patients of our(More)
BACKGROUND AND PURPOSE High fibrinogen levels have been assessed in cerebrovascular disease with a direct relation to both plasma and whole-blood viscosity, as well as cerebral blood flow. Heparin-induced extracorporeal low density lipoprotein precipitation (HELP) is a new method that safely and effectively reduces fibrinogen and plasma lipoproteins and(More)
BACKGROUND The H.E.L.P. (Heparin-induced extracorporal low-density lipoprotein precipitation) system selectively eliminates fibrinogen, LDL (low-density lipoprotein) cholesterol, triglycerides, and LP (a) (lipoprotein a) from the blood plasma by means of extracorporal circulation. The reduction of these macromolecules immediately improves the(More)
Cerebrovascular disease (CVD) is associated with high fibrinogen levels and lipid fractions leading to an increase of both plasma and whole blood viscosity as well as raised aggregability of blood cells. One important goal in the treatment of cerebral multiinfarct dementia (MID) therefore should be to reduce fibrinogen and lipoproteins and thereby to(More)
Reproductive effort, factors affecting reproductive output and costs of reproduction were studied in primiparous yearling compared to multiparous older female European ground squirrels (Spermophilus citellus). Yearling females weaned smaller litters than older ones. Litter size increased with posthibernation body mass at the expense of slightly lighter(More)
The course of behavioral and vaginal estrus and patterns of circulating estrogens were followed in free-living European ground squirrels (Spermophilus citellus) after their emergence from hibernation. Normally mating females were compared to a second group in an area where males had been removed from the population before female emergence. Both groups(More)
Back pain and the whiplash syndrome are very common diseases involving tremendous costs and extensive medical effort. A quick and effective reduction of symptoms, especially pain, is required. In two prospective randomized studies, patients with either lumbar radiculopathy in the segments L5/S1 or the whiplash syndrome were investigated. Inclusion criteria(More)
• Background: Heparin-induced extracorporeal LDL/fibrinogen precipitation (HELP) eliminates selectively fibrinogen, LDL, cholesterol, triglycerides and LP(a) from blood plasma using extracorporeal circulation. The reduction of fibrinogen and LDL by about 50% after only one procedure immediately improves the hemorheological situation. • Method: In a(More)
In seasonally breeding mammals, in particular hibernators, reproduction underlies severe energetic and temporal constraints to enable the allocation of sufficient body fat reserves before winter. Thus, the timing of conception in spring can be crucial in terms of reproductive success. This study investigates follicular development in European ground(More)
