Cortical projection to the subventricular zone and its effect on adult neurogenesis in mice.

Various brain regions/nuclei project axons to the subventricular zone (SVZ), a postnatal neurogenic niche. In adults, neurogenesis is controlled by neuronal activity, via neurotransmitters. Glutamate is a major excitatory neurotransmitter, and glutamate receptors are expressed in SVZ cells.

Improvement in Double Staining With Fluoro-Jade C and Fluorescent Immunostaining: FJC Staining Is Not Specific to Degenerating Mature Neurons.

Fluoro-Jade C (FJC) staining has been used to detect degenerating neurons in tissue sections. It is a simple and easy staining procedure and does not depend on the manner of cell death. In some experiments, double staining with FJC and fluorescent immunostaining (FI) is required to identify cell types.

[Acute gastric mucosal lesions caused by acute Helicobacter pylori infection -clinical outcomes of six cases and problems in the diagnosis of H. pylori infection].

We analyzed the ratio of positive test results in various diagnostic methods for Helicobacter pylori infection and the clinical presentations in six cases of acute gastric mucosal lesions (AGML) caused by acute H. pylori. At onset, five cases tested negative for serum antibodies; one had a positive result, but the antibody titer increased with time.
