Brucellosis presenting with pancytopenia and hearing loss: A case report.

Background: Brucellosis is one of the most common zoonotic infectious diseases in the world, with approximately 500000 new cases of human brucellosis diagnosed each year. Brucellosis can simulate various multi-system diseases, presenting atypical symptoms. Very few brucellosis cases with pancytopenia accompanied by a severe hearing loss have been reported.

Modulation of Glucose Takeup by Glucose Transport on the Isolated OHCs.

Glucose is a fundamental source of energy for mammalian cells; however, whether glucose is taken up through the lateral walls of cochlear outer hair cells (OHCs) is unknown. The OHC lateral wall is complex, composed of a plasma membrane, cortical lattice, and subsurface cisternae. This study assessed the uptake of glucose by OHCs using live-cell microscopy and examined the distribution of glucose transporter isoforms by immunohistochemistry.

Clinical Study on 136 Children with Sudden Sensorineural Hearing Loss.

Background: The prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL.

A low-cost light-emitting diode induced fluorescence detector for capillary electrophoresis based on an orthogonal optical arrangement.

In this work, a simple and low-cost miniaturized light-emitting diode induced fluorescence (LED-IF) detector based on an orthogonal optical arrangement for capillary electrophoresis (CE) was developed, using a blue concave light-emitting diode (LED) as excitation source and a photodiode as photodetector. A lens obtained from a waste DVD-ROM was used to focus the LED light beam into an approximately 80 microm spot. Fluorescence was collected with an ocular obtained from a pen microscope at 45 degrees angle, and passed through a band-pass filter to a photodiode detector.
