direct hormone evidence to confirm the pangolin’s gestation period. Therefore, the researchers had a study in Taipei Zoo to concentrate the serum progesterone in three pregnant and two non-pregnant rescued female Manis pentadactyla. In fact, the aim of this study is to evaluate the gestation period of limited number of rescued Manis pentadactyla using Progesterone Radioimmunoassay (P4 RIA) detection in serum samples.

X-chromosome monosomy, X-chromosome mosaicism, and X-chromosome defects are common causes of the absence or alterations of the X-chromosome. Monosomy X occurs in about half of the girls with Turner syndrome. This means that each cell in each of their bodies has only one copy…

Background Considerable biologic evidence supports the importance of estrogen to cognitive function. Some studies have investigated the use of hormone replacement therapy (HRT) to reduce the risk of developing dementia. However, data from the Women's Health Initiative (WHI) and the WHI Memory Study (WHIMS) do not support these observations, and suggest that estrogen replacement does not protect against dementia and may increase the risk. This topic is controversial and now discussed. Our study…
