overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (copd) and obstructive sleep apnea (osa), was first defined by flenley. although it can refer to concomitant occurrence of any of the pulmonary diseases and osa, overlap syndrome is commonly considered as the coexistence of osa and copd. this disease has unique adverse health consequences distinct from ...

Last years, Wavelet Packet Modulation (WPM) or Wavelet Packet Transform based Orthogonal Frequency Division Multiplexing (WPT-OFDM) have been introduced to wired and wireless communication fields as efficient Multicarrier Modulation (MCM) techniques. The wavelets have interesting features such as flexibility, compatibility and localization in both time and frequency domains with no need to use ...

background: knowing the rate of overlapping in results obtained from information retrieval tools is important to prevent waste of time. medical and health-related information has an outstanding place among the variety of information available on the internet. hence, this research aimed to study the rate of overlap among medical search results derived from mesh (medical subject headings) in gene...

purpose: the purpose of this study was to investigate the structure of the discipline categorization and its overlap with isi subject categories. this will help detect the systematic errors arising from the scientometrics studies. methodology: the scientometrics methodology was used. all articles which were indexed in the web of science database (2007) and also the articles citing them during 2...

BackgroundLead is a strong and stable toxin, harmful especially to children, pregnant women, and the elderly. Nearly 27% of children aged under 5 years suffer from failure to thrive (FTT). Due to the probable harmful effects of lead poisoning on children’s growth, in this study we aimed to assess the blood lead level in children with unexplained failure to thrive.MethodsThis analytic cross-sect...

Introduction:The overlap syndrome, consisting ofobstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructvie pulmonary disease (COPD) is a major problem in COPD patients. OSHAS corresponds to the likelihood of systemic hypertension.The present study was aimed to evaluate the association between apnea-hypopnea index and diastolic blood presssure (DBP) in overlap  patients. Materials...
