Microcenoscelis n. gen. (Coleoptera: Tenebrionidae: Ulomini) from tropical Africa, with description of a blind species from Zimbabwe.

Microcenoscelis n. gen. (Coleoptera: Tenebrionidae: Ulomini) caeca n. sp. is described from Zimbabwe, a small and completely blind species. A second known species, however with completely developed eyes, and originally described as Uloma minuscula Ardoin, 1969, was also placed in the new genus. Microcenoscelis n. gen. seems to be mostly related to the genera Cenoscelis Wollaston, 1867, and Cneo...

Factors influencing retrograde conduction. Study of 30 patients during cardiac catheterization.

Retrograde conduction from ventricle to atrium is a well-recognized occurrence in the human heart. The phenomenon has been observed repeatedly during ventricular tachycardia (Kistin, 1961), with ventricular premature and interpolated beats (Kistin, 1959, 1963; Kistin and Landowne, 1951), in patients with ventricular pacemakers (Kastor and De Sanctis, 1967; Barold, Linhart, and Samet, 1968), and...

Wealth Concentration in a Developing Economy: Paris and France, 1807–1994

Using large samples of estate tax returns, we construct new series on wealth concentration in Paris and France from 1807 to 1994. Inequality increased until 1914 because industrial and financial estates grew dramatically. Then, adverse shocks, rather than a Kuznets-type process, led to a massive decline in inequality. The very high wealth concentration prior to 1914 benefited retired individual...

Brachydactyly in an Indian family.

Brachydactyly was the first case of Mendelian inheritance shown in man and was reported to be a simple dominant (Farabee, 1905). Since then, pedigrees have been published showing this pattern of inheritance. The term brachydactyly is generally used to describe a number of abnormal conditions which result in the shortening of one or more digits, and these have been grouped into five main types b...
