Prevalence of the Accessory Cardiac Bronchus on Multidetector Computed Tomography: Evaluation and Proposed Classification.

Purpose: Accessory cardiac bronchus (ACB) is a very rare congenital anomaly and may cause some clinical complications, such as recurrent episodes of both infection and hemoptysis. The purpose of this study was to assess the multidetector computed tomography (MDCT) characteristics of ACB and to classify this anomaly according to the MDCT aspects.

Materials And Methods: The routine thoracic CT scans from 5790 patients were evaluated retrospectively.

Increased adult neurogenesis in the subventricular zone in a rat model of sepsis.

Neurogenesis occurs in the adult brain throughout the lives of all mammals. The dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles have been established as the primary sites of adult neurogenesis, and recent studies have shown that inflammation has a modulating effect on adult neurogenesis. However, only limited studies have investigated how neurogenesis is affected during sepsis and sepsis-associated encephalopathy.

Sepsis induces apoptotic cell death in different regions of the brain in a rat model of sepsis.

Sepsis occurs in 14-37 percent of patients admitted to intensive care units and sepsis associated encephalopathy (SAE) is its severe complication. In an attempt to provide insight into the question how sepsis and SAE contributes cerebral dysfunction, apoptotic cell death was investigated in hippocampal formation, centers of adult neurogenesis and main autonomic centers which are known to regulate heart rate, respiration and other visceral activities, in cecal ligation and puncture (CLP) rat model of sepsis. Vital parameters and electrophysiological changes were monitored for the confirmation of sepsis and SAE, respectively.

Alterations in the brain electrical activity in a rat model of sepsis-associated encephalopathy.

Sepsis and septic shock are the commonest causes of death in the intensive care units. Although recent research have improved our understanding of the progress and pathophysiology of sepsis and septic shock, underlying mechanisms in sepsis-associated encephalopathy is still poorly understood. The incidence of sepsis-associated encephalopathy has been reported to vary from 8% to 70% of septic patients.
