some mutant tubules were either devoid of germ cells or contained diminished numbers of spermatogenic cells (Fig.2f, g). These defects were more severe at P21, in which more than half of thePramef12Nulltubules were agametic and the remaining tubules contained reduced numbers of germ cells (Fig...
Similarly, the role of microvascular pathology, iron deposition, axonal injury, neuroinflammation and astrocytosis to the pathogenesis of CTE pathology needs resolution. Future investigation will be needed to understand the relationship of the pathology to the clinical symptoms, genetics, neuroimaging and ...
Insemination in scorpions is carried out by means of a partly sclerotized structure, the spermatophore, which is composed of two separate halves, the hemispermatophores. In most genera these reproductive structures can be used to differentiate species. However, many taxa such as the genusEuscorpius...
