Endothelial function markers in parkinsonian patients with hyperhomocysteinemia.

Hyperhomocysteinemia is considered a risk factor for vascular disease causing endothelial damage and consequently atherogenesis. The purpose of this study was to investigate the effect of elevated homocysteine on certain biochemical markers of endothelial function in patients with idiopathic Parkinson's disease (PD). Blood homocysteine levels were assessed in 57 PD patients and 40 matched normal controls.

Effects of face and name presentation on memory for associated verbal descriptors.

Sixty-four participants were tested on immediate and delayed recall of verbal information about people accompanied by photographs of them, in comparison to verbal information about people accompanied by written names of them. Forty-two descriptive sentences were shown in a fixed random order, each associated with a photograph of one of 6 people (7 facts per depicted person), and another 42 sentences were paired with the written name of one of 6 people (7 facts per named person). Participants had to recall as many facts about each face or name as they could, 5 min after the presentation and then a week later.
