the prevalence of exercise induced asthma (eia) in iran is not known. in the present study the  prevalence of  eia  among female students  of  guidance school  in the  city of mashhad was evaluated. a total of 1690 female students aged 12-14 years in ten randomly selected schools in north east of iran (mashhad) completed an asthma symptoms- specific questionnaire. one hundred forty four randoml...

Pore-formation in cell membranes is used by many toxins to kill cells. It is usually a process involving multiple steps that are difficult to analyse at the molecular level. The use of surface plasmon resonance (SPR) has only recently been introduced into the study of pore-forming toxins (PFT). It can give useful data mostly on the first steps of the pore-forming process; the binding to the lip...

We describe a generalization of Puff Field Theory to p+1 dimensions where 0 ≤ p ≤ 5. We then focus on the case of p = 0, “Puff Quantum Mechanics,” and construct a formulation independent of string theory. Melvin twist, also known as the T-s-T transformation, is a powerful solution generating technique in string and supergravity theories [1–6]. Melvin twist of flat spaces retains the simplicity ...

Chagas disease is one of the major neglected diseases of the world. Existing drug therapies are limited, ineffective, and highly toxic. We describe a novel strategy of drug discovery of adapting an existing clinical compound with excellent pharmaceutical properties to target a pathogenic organism. The protein farnesyltransferase (PFT) inhibitor tipifarnib, now in phase III anticancer clinical t...

Shape is an important aspects in recognizing plants. Several approaches have been introduced to identify objects, including plants. Combination of geometric features such as aspect ratio, compactness, and dispersion, or moments such as moment invariants were usually used toidentify plants. In this research, a comparative experiment of 4 methods to identify plants using shape features was accomp...

Experimental data obtained for PbFe1/2Ta1/2O3 (PFT) and NaNbO3: Gd (NaNbGd) single crystals show a diffused dielectric permittivity peak that is inherent to relaxor ferroelectrics. However some deviations from the normal relaxor properties were also observed and are under discussion. One of the key features of the relaxors is the existence of the Burns temperature, at which the polar regions ap...

Abstract Background Plantar fasciitis is a common cause of heel pain. Understandably knowledge normal sonographic plantar fascia thickness (PFT) crucial to diagnose this condition as thickened the most important ultrasound finding for its diagnosis. Objective The objectives study are compare PFT among heavy weight bearing and non‐weight individuals sonographically assess effect age, gender body...

Abstract To evaluate the relationship of cardiac function, including time-volume-curves, with lung volumes derived from pulmonary function tests (PFT) and MRI in subjects without cardiovascular diseases. 216 underwent whole-body spirometry as part KORA-FF4 cohort study. Lung semi-automatically using an in-house algorithm. Forced expiratory volume one second (FEV1), forced vital capacity (FVC), ...

background: despite wide application of chromium in electroplating industry, the pulmonary effects of chronic exposure to this chemical have not been extensively studied and are subject of debate and controversy. this study was, therefore, undertaken to further address this issue.   methods: the study population consisted of a group of 15 workers with a history of past and present occupational ...
