Masking Release for Speech in Modulated Maskers: Electrophysiological and Behavioral Measures.

Objectives: The purpose of this study was to obtain an electrophysiological analog of masking release using speech-evoked cortical potentials in steady and modulated maskers and to relate this masking release to behavioral measures for the same stimuli. The hypothesis was that the evoked potentials can be tracked to a lower stimulus level in a modulated masker than in a steady masker and that the magnitude of this electrophysiological masking release is of the same order as that of the behavioral masking release for the same stimuli.

Design: Cortical potentials evoked by an 80-ms /ba/ stimulus were measured in two steady maskers (30 and 65 dB SPL), and in a masker that modulated between these two levels at a rate of 25 Hz.

The effectiveness of massage in therapy for obturator nerve dysfunction as complication of hip joint alloplasty-case report.

Unlabelled: The purpose of our case presentation was to reveal effectiveness of medical massage in the therapy for obturator nerve dysfunction as a complication of hip joint alloplasty.

Design: Medical massage was carried out in a 58-year-old man after hip joint alloplasty. The aim was to normalize tension of muscle-ligament-fascia apparatus within pelvic girdle and reconstruct correct structural conditions in the course of obturator nerve.

Serum tumor markers in non-small cell lung cancer. A comparative analysis.

Background: The role of serum tumor markers in non-small cell lung cancer (NSCLC) remains undefined. New proposed markers have seldom been rigorously compared with existing standards. The authors prospectively compared the performance of three new monoclonal antibodies (MoAb) (5E8, 5C7, and 1F10) with the established serum markers carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC).

Deposition of circulating streptococcal lipoteichoic acid in mouse tissues.

The tissue binding properties of streptococcal lipoteichoic acid (LTA) were studied using normal and passively immunized BALB/c mice. After intraperitoneal injection in non-immunized mice, 3H-LTA concentrations in blood, heart, kidney and liver were highest between 24 and 30 h post-injection. LTA deposits in heart remained high for the next 24 h, whereas other tissue levels decreased.
