Cognitive maps of environmental knowledge and preference in nursing home patients. | Two studies examined cognitive maps of environmental knowledge and preference shown by nursing home patients. In study I, knowledge of the nursing home environment was investigated. Age was found to be negatively related to accuracy in identifying the locations of slide-depicted scenes. Also, patients who had lived sev... | 679,967 | [

Erythrocytophagocytosis by arterial smooth muscle cells in experimental atherosclerosis. | The morphological examination of advanced atherosclerosis caused by atherogenic diet in the coronary arteries and in the aorta abdominalis (trifurcation) of pigs showed plaque hemorrhage and signs of vascularisation.

Corrosion of copper in utero. | The influence of corrosion on the copper wire in the Copper T-200 intrauterine device (IUD) was studied in devices which had been in utero for 3 to 52 months. This was done mainly by examining cross-sections of the wires under a light microscope. Corrosion was normally localized to narrow areas and led to breakage and ... | 680,184 | [

Low levels of serum calcium, phosphorus and plasma 25-hydroxy vitamin D in cirrhosis of the liver. | In a retrospective analysis of 78 patients with liver cirrhosis, we found low serum levels of calcium and phosphorus. The low calcium levels showed a better correlation with high activity of aspartate aminotransferase than with low levels of albumin. In addition, there was a relationship between low calcium and low pho... | 681,162 | [
