Background: Chronic obstructive pulmonary disease, which is usually caused by harmful particles or gases, associated with persistent respiratory symptoms. Aim: To determine effects of controlled breathing techniques for muscle strengthening and functional capacity. Study Design: Randomized control trial. Methodology: was conducted at Services Hospital Lahore duration 6months. Patients (n=48) we...

STUDY OBJECTIVES To investigate the effect of volitional pursed-lips breathing (PLB) on breathing pattern, respiratory mechanics, operational lung volumes, and dyspnea in patients with COPD. SUBJECTS Eight COPD patients (6 male and 2 female) with a mean (+/-SD) age of 58 +/- 11 years and a mean FEV1 of 1.34 +/- 0.44 L (50 +/- 21% predicted). METHODS Wearing a tight-fitting transparent facem...

Dyspnea is a cardinal symptom of chronic obstructive pulmonary disease (COPD), and its severity and magnitude increases as the disease progresses, leading to significant disability and a negative effect on quality of life. Refractory dyspnea is a common and difficult symptom to treat in patients with advanced COPD. There are many questions concerning optimal management and, specifically, whethe...

Synthetic biology is considered as an emerging research field that will bring new opportunities to biotechnology. There is an expectation that synthetic biology will not only enhance knowledge in basic science, but will also have great potential for practical applications. Synthetic biology is still in an early developmental stage in China. We provide here a review of current Chinese research a...

This is a review of physiological and clinical aspects on training of the respiratory muscles in chronic obstructive pulmonary disease (COPD) patients. Three types of exercise training have been used: strength, endurance, and co-ordination. With each type, intensity of the stimulus, specificity and the proper evaluation of the training are important. The rationale for training respiratory muscl...

Single image blind deblurring has been intensively studied since Fergus et al.’s variational Bayes method in 2006. It is now commonly believed that the blurkernel estimation accuracy is highly dependent on the pursed salient edge information from the blurred image, which stimulates numerous l0-approximating blind deblurring methods via kinds of techniques and tricks. This paper, however, focuse...

BACKGROUND The aim of this study is to evaluate and quantify dynamic soft-tissue strain in the human face using real-time 3-dimensional imaging technology. METHODS Thirteen subjects (8 women, 5 men) between the ages of 18 and 70 were imaged using a dual-camera system and 3-dimensional optical analysis (ARAMIS, Trilion Quality Systems, Pa.). Each subject was imaged at rest and with the followi...
