The Wisconsin Card Sorting Test (WCST) is a neuropsychological test, hypothesized to be an indicator of dorsolateral prefrontal cortex (DLPFC) functioning. The performance of schizophrenic patients in our sample (off medication) was worse than the performance of healthy controls in all variables of the WCST, including perseverative responses (PR) as well as(More)
Late-onset depression (greater than or equal to 60 years) is believed to be less associated with a risk of depression in first-degree relatives than early-onset depression. However, family studies in elderly probands fitting the current methodological standards of family studies are not available. The reported family study in geriatric inpatients with(More)
In a search for an external validation of the negative syndrome construct and the attentional impairment item on Andreasen's scale, 49 unmedicated schizophrenic patients were administered the Span of Apprehension Test and a Continuous Performance Test with two levels of difficulty. This schizophrenic sample performed significantly more poorly on the(More)
The therapeutic effect of the alpha 2-antagonist yohimbine in erectile dysfunction was studied in a double-blind placebo-controlled design. Thirty-one male patients underwent extensive clinical, urological, and psychiatric diagnosis and were dichotomically classified into an organic and a nonorganic subgroup. Following a 1-week placebo run-in period,(More)
The endogenous/non-endogenous distinction of unipolar major depression is widely accepted, as is the family study approach to the validation of diagnostic distinctions. Rates of affective disorders were examined in 689 first-degree relatives of 184 patients with unipolar major depresion and were compared with 312 first-degree relatives of 80 healthy(More)
Photochromic fulgides are UHV-deposited in ultrathin films exhibiting intrinsic nanostructures. The two isomeric states (C and E) are detected in absorption via scanning near-field optical microscopy (SNOM). The optical image contrast measured in SNOM corresponds to the nanostructure topography observed in atomic force microscopy. Nano-optical reversible(More)
We will construct a family of permutations having an entropy of lower order than their actual rearrangement-complexity. This result is a solution of an open problem that arose in the context of a result obtained by Stoß [6], who showed that entropy yields a lower bound for complexity of permutations. Besides this we present some interesting results(More)
