There is little literature about the mortality associated with bronchiectasis. The aim of the present study was to investigate factors affecting mortality in patients with bronchiectasis. In total, 91 patients were examined for aetiology, pulmonary function tests, high-resolution computed tomography, sputum microbiology and quality of life scores and were(More)
Early results of a continuing study of the electrical activity of muscles after transfer, with an integrated system of electromyographic and video tape recording, recorded motions of the simple voluntary type, mostly with isometric contractions. A triceps-to-biceps transfer showed activity in the new motion one day after operation. A partial transfer of the(More)
OBJECTIVE To study the electromyographic profile--including ON, OFF, and peak timing locations--of the lateral gastrocnemius muscle over a wide range of walking speeds (0.5-2.1 m/sec) in healthy young adults. DESIGN We studied gastrocnemius muscle-firing patterns using an electromyographic surface electrode in 15 healthy subjects ambulating on a treadmill(More)
BACKGROUND Uncontrolled proliferation is a hallmark of malignant tumour growth. Its prognostic role in non-small cell lung cancer (NSCLC) has been investigated in numerous studies with controversial results. We aimed to resolve these controversies by assessing the Ki-67 proliferation index (PI) in three large, independent NSCLC cohorts. METHODS(More)
Spasticity in stroke patients interferes with coordinated muscle firing patterns of the lower extremity leading to gait abnormalities. The goal of this study was to improve ankle function during walking by augmenting treadmill gait retraining with a visual EMG biofeedback technique. Eight stroke patients who could ambulate between 0.5 and 0.9 m/s(More)
PURPOSE Molecular features of non-small cell lung cancer (NSCLC) in never-smokers are not well recognized. We assessed the expression of genes potentially related to lung cancer etiology in smoking vs. never-smoking NSCLC patients. METHODS We assayed frozen tumor samples from surgically resected 31 never-smoking and 54 clinically pair-matched smoking(More)
The fact that growth and spread of tumours are dependent on angiogenesis has led to the investigation of the role of anti-angiogenic agents in the therapeutic strategies for thoracic tumours such as nonsmall cell lung cancer or mesotheliomas. Since various angiogenic factors may contribute to the regulation of angiogenesis in the individual tumour, in the(More)
In this study, we investigated the behavior of active motor units identified via analysis of electro myographic (EMG) signals recorded from the first dorsal interosseous (FDI) muscle using a quadrifilar needle electrode. Data was collected from control subjects and patients with both upper (UMN) and lower (LMN) motor neuron dominant forms of amyotrophic(More)
