Does testosterone differ between suicide attempters and community controls in men and women of China?
Testosterone, as a form of physiological marking, is somewhat another predictor of attempted suicide. Besides other factors, it might be the testosterone, not gender, which explains the suicide risks and the gender ratio of the rates. The lack of sample size limited this current study to establish a significant and positive relationship between testosterone and suicide risk in women as found in men.
The present data provides the first direct evidence of an immunological capacity of the human endolymphatic sac. At the molecular level, the endolymphatic sac is capable of antigen recognition and processing for initiation of an immune response. In addition, potent molecules directly toxic to invading pathogens are expressed by the sac epithelium. This evidence strongly supports the endolymphatic sac as a significant immunological entity of the inner ear.
