This study examined the relationship between neuron density in the stellate ganglion and the severity of basilar artery (BA) enlargement after bilateral common carotid artery ligation. ⋯ High neuron density in stellate ganglia may protect against steno-occlusive carotid artery disease by preventing BA dilatation and aneurysm formation in the posterior circulatory arteries.

An alternative caudally directed C2 inferior facetal screw is described. Such screw insertion can form the axial stabilization point in cases undergoing atlantoaxial lateral mass plate/rod and screw fixation and those undergoing C1-2 and C1-2-3 spinal fixation. The C2 screw courses from the medial point of the pedicle-laminar junction and travels caudally and laterally toward the C2-3 articulation. ⋯ The technical issues, anatomic subtleties, and indication for use of the C2 inferior facetal screws are discussed. With an average follow-up of 9 months, all screws have successfully provided stability that resulted in arthrodesis of the treated spinal segments. A caudally directed C2 inferior facetal screw can enhance the armamentarium of the surgeon, provide an alternative to conventional techniques or a bailout option, and add to the safety of the procedure of atlantoaxial lateral mass fixation in anatomically challenged situations.

The aim of this study was to determine whether hyperbaric oxygen (HBO) therapy causes attenuation of traumatic brain injury (TBI)-induced depression-like behavior and its associated anti-neuroinflammatory effects after fluid percussion injury. ⋯ Our results suggest that HBO treatment may ameliorate TBI-induced depression-like behavior in rats by attenuating neuroinflammation, representing one possible mechanism by which depression-like behavior recovery might occur. We also recommend HBO as a potential treatment for TBI-induced depression-like behavior if early intervention is possible.

Bromocriptine (BRC) is effective in patients with prolactinoma. However, the cytotoxic mechanism of BRC remains unknown. ⋯ BRC-treated pituitary adenoma cells mainly underwent autophagic cell death rather than apoptosis.
