Abstract:
A review of mortality from the 1850 census mortality schedules of Natchitoches Parish, Louisiana has provided a snapshot of the health conditions of African-American slaves. The cause of death was abstracted from the mortality schedule and categorized according to the ninth revision of the Manual of the International Classification of Diseases. Children under the age of 9 accounted for 44% of the total mortality. Sixty-four percent of all deaths recorded occurred in the slave population. Sixty-two percent of the slave deaths occurred in the male population. Leading causes of death were helminthiasis, whooping cough, fever, cholera, and pneumonia. Reports of mortality due to Cachexia Africana (dirt eating) among slaves are discussed.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
