In a very interesting paper published recently in the Brazilian Journal of Pulmonology, Queiroz et al. (1) reported a COPD underdiagnosis rate of 71.4% in a primary health care setting. In addition, the authors observed that only 5.6% of the subjects previously diagnosed with COPD had undergone pulmonary function tests (PFTs). We would like to recount our experience concerning the underutilizat...

The phytoplankton absorption cross-section is a fundamental quantity in biogeochemical ocean models that alters the underwater spectral light field and photosynthetic response of phytoplankton. Phytoplankton taxa are characterized by spectra with defined bands visible region spectrum govern capability different to exploit as resource for growth. interplay between spatial temporal gradients char...

Background Chronic obstructive pulmonary disease (COPD), the third leading cause of death worldwide, is often underdiagnosed. Purpose To develop machine learning methods to predict COPD using chest radiographs and a convolutional neural network (CNN) trained with near-concurrent function test (PFT) data. Comparison made natural language processing (NLP) associated radiologist text reports. ...

Pore-forming toxins (PFTs) are commonly associated with bacterial pathogenesis. In eukaryotes, however, PFTs operate in the immune system or are deployed for attacking prey (e.g. venoms). This review focuses upon two families of globular protein PFTs: the cholesterol-dependent cytolysins (CDCs) and the membrane attack complex/perforin superfamily (MACPF). CDCs are produced by Gram-positive bact...

Bronchiolitis obliterans (BO) is a serious noninfectious pulmonary complication following allogeneic bone marrow transplantation (BMT). Azithromycin, a macrolide antibiotic, may have a beneficial effect in BO through its anti-inflammatory effect. The aim of the current study was to investigate the potential effect of azithromycin on pulmonary function tests (PFTs) in BO complicating BMT. PFTs o...

BACKGROUND The Cystic Fibrosis (CF) Foundation recommends patients attend clinic ≥4 times per year with 4 respiratory cultures and 2 pulmonary function tests (PFTs). However, nationally only 57.4% of patients met these guidelines in 2012. We used a quality improvement program with a goal of 75% of our patients meeting this care guideline by 2012. METHODS A 2-stage program was started in 2011....

PURPOSE We studied symptomatic radiation pneumonitis (RP) and changes in pulmonary function tests (PFTs) after loco-regional radiotherapy (LRRT) with V20 lung constraints in breast cancer (BC). PATIENTS AND METHODS Sixty-four women underwent PFTs before and 5 months after 3D planned LRRT for BC. The incidentally irradiated ipsilateral lung V20 was minimised to <30%. Patients were monitored fo...

32 33 Marine plankton ecosystems are an important component of biogeochemical cycling in the oceans. 34 Operational plankton functional type (PFT) models, that group plankton according to their 35 biogeochemical properties, are currently being developed to resolve biogenic gas exchange between 36 the ocean and atmosphere, and to model the lowest trophic levels in fisheries models. A 37 fundamen...

مگس مینوز سبزی و صیفی Liriomyza sativae Blanchard ، از مهم­ترین آفات ‌های گلخانه ای فضای باز، محسوب می شود. با توجه به توصیه کاربرد حشره­ کش تیوسیکلام جهت مدیریت آفت مزبور، در پژوهش حاضر، اثرات کشندگی زیرکشندگی(5/131:LC30، 1/87:LC20، 15/49:LC10 میلی گرم ماده موثره بر لیتر) حشره ­کش (اویسکت®SP50%) روی فراسنجه ­های زیستی این شرایط آزمایشگاهی مورد ارزیابی قرار گرفت. روش استفاده انجام آزمایش­ها غوط...
