This paper describes a disease pattern with a distinctive clinico-radiological picture but of an undetermined pathology. The main features are quietening of the breath sounds and lessening of the radiographic lung markings with persistently greater transradiancy over one lung, the condition being distinguishable from simple unilateral obstructive emphysema by the small or normal size of the aff...

Eighteen years after an uneventful renal transplantation, the chest radiograph of an asymptomatic 50 year old man showed diffuse bilateral infiltrations, predominately at the right apex. Computed tomography (CT) scan demonstrated a diffuse alveolar pattern, the alveoli being filled with a very dense material, with some tracheal calcifications. Bronchoalveolar lavage fluid analysis was normal, b...

Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal low-grade B-cell lymphoma. Pulmonary MALT lymphoma is considered to originate from bronchial MALT and is also referred to as bronchial-associated lymphoid tissue lymphoma. Pulmonary MALT lymphoma is a rare disease, but it is the most frequent subset of primary pulmonary lymphoma. The median age at diagnosis of pulmonary MALT lym...

In regional lung injury, pulmonary blood flow decreases to the injured regions, and anastomotic bronchial blood flow and total bronchial blood flow increase. However, the pattern of redistribution of the two blood flows to the injured and noninjured areas is not known. In six anesthetized sheep, pulmonary and bronchial blood flows were measured with 15-microm fluorescent microspheres by using t...

Aerosolized medications are frequently used in the pulmonary function laboratory. The 2 most common implementations are bronchodilators and bronchial challenge agents. Bronchodilator administration is not well standardized, largely because of the various methods of delivery available for clinical practice. Metered-dose inhalers used with spacer devices are the most common route for bronchodilat...

The relative roles of the endosomal TLR3/7/8 versus the intracellular RNA helicases RIG-I and MDA5 in viral infection is much debated. We investigated the roles of each pattern recognition receptor in rhinovirus infection using primary bronchial epithelial cells. TLR3 was constitutively expressed; however, RIG-I and MDA5 were inducible by 8-12 h following rhinovirus infection. Bronchial epithel...

The aim of our study was to determine the prevalence of anatomical variants of bronchial arteries using computed tomographic angiography in a population of northeastern Mexico. An observational, transversal, descriptive, comparative, retrospective study was performed using 139 imaging studies of Mexican patients in which we evaluated the following parameters from the left and right bronchial ar...

in asthmatic subjects there is a pronounced diurnal variation in bronchial responsiveness. if this phenomenon is due to variation in factors that control drug delivery, then it should be paralleled by a similar variation in competitive antagonist blockade. in order to study this possibility, we performed the methacholine challenge test and after 45 minutes, administered atropine by inhalation. ...

results: the lowest concentrations of nzvi that inhibited the visible growth (mic) of e. amylovora, x. oryzae, b. cereus and streptomyces spp. were 625, 550, 1250 and 1280 ppm, respectively. the minimum bactericidal concentration (mbc) for e. amylovora and x. oryzae were 10,000 and 5,000 ppm of nzvi, respectively. mbc was not observed for the gram positive bacteria. no bacteriostatic and bacter...

Sulfur mustard (SM) is a strong alkylating and mutagenic compound that targets humanairway system. We considered the expression of Forkhead box M1 (FOXM1) and apolipoproteinE (APOE) genes, which are responsible for cell proliferation, differentiation, tumorigenesis,and increased risk of lung cancer, in the lung bronchial tissue of patients exposed to SM.After performing pulmonary functional tes...
