The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421 bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (> 3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe. 相似文献

Under what conditions do women participate in executive power in multiethnic societies? Previous research has examined how political institutions, socioeconomic factors, and cultural norms affect the appointment of women as cabinet ministers. However, no study has assessed the extent to which the politicization of ethnicity—a cleavage that shapes political life in many countries—affects women's cabinet appointments. Focusing on sub‐Saharan Africa, we argue that women are less likely to become cabinet ministers where incumbents use such appointments to build patronage‐based alliances with politicians who act as advocates for ethnic constituencies. Using an original dataset on the composition of cabinets in 34 African countries from 1980 to 2005, we show that women's share of cabinet appointments is significantly lower in countries where leaders must accommodate a larger number of politicized ethnic groups, but it rises with higher levels of democracy and greater representation of women in parliament. 相似文献

Aortic aneurysm refers to the pathological dilatation of the normal aortic lumen involving one or several segments. Thoracic aortic aneurysms are much less common than aneurysms of the abdominal aorta. Descending thoracic aortic aneurysm leading to dissection and spontaneous rupture is a potentially catastrophic illness. Although rare, dissection and rupture of a preexisting aortic aneurysm have been reported during pregnancy and early puerperium. To the best of our knowledge, such cases among young pregnant women are rarely reported in literature. Herein, an autopsy case of spontaneous rupture of a clinically undiagnosed descending thoracic aortic aneurysm during early puerperium in a young woman is presented along with the review of relevant literature. The victim was found dead on her hospital bed on the seventh day of puerperium. Autopsy with ancillary investigations revealed that the young woman died because of hemothorax from a ruptured dissecting descending thoracic aortic aneurysm secondary to chronic aortitis. 相似文献
