Contrary to the expected XX/XY sex chromosome complements in hermaphroditism, a variety of karyotypes have been reported instead. Dewhurst et al. (1965) summarized from published reports the karyotypic findings in 27 patients with convincing evidence ofhermaphroditism, as follows: 46,XX (17); 46,XY (2); 46,XX/47,XXX (1); 46,XX/46,XX + Frag (1); 46,XX/46,XY (3); 46,XX/47,XXY/ 49,XXYYY (1); 46,XX...

This study examined photoperiodic regulation of affective behaviours in collared lemmings (Dicrostonyx groenlandicus). Male and female lemmings were housed in either long (LD 22:2), intermediate (LD 16:8), or short days (LD 8:16) for 9 weeks. Exposure to short days induced moult to a winter pelage and gonadal regression in male, but not female, lemmings. Lemmings housed in long days reduced anx...

2014 The role of interplanar fluctuations associated with « parallel » vortex loops is considered in the two coupled problems of XY magnetism and superconductivity of the second kind, in a quasitwodimensional situation. Using an admittedly simplified criterion, it is argued that, for weak interplanar couplings, the critical 3d temperature is related to the multiplication of such loops ; it shou...

The belief that Homo sapiens is absolutely dimorphic with the respect to sex chromosome composition, gonadal structure, hormone levels, and the structure of the internal genital duct systems and external genitalia, derives from the platonic ideal that for each sex there is a single, universally correct developmental pathway and outcome. We surveyed the medical literature from 1955 to the presen...

In many cases of callosal dysgenesis in both human patients and mouse models, misguided fibers from the cortex form abnormal bilateral, barrel-shaped structures known as Probst bundles. Because little is known about how axons are arranged within these anomalous fiber bundles, understanding this arrangement may provide structural and molecular insights into how axons behave when they are misguid...
