Like other intronless G protein coupled receptor genes, the beta2-adrenergic receptor (beta2AR) has minimal genetic space for population variability, and has attained such via multiple coding and noncoding polymorphisms. Yet most clinical studies use the two nonsynonymous polymorphisms of the coding region for association analysis despite low levels of linkage disequilibrium with some promoter and 5'UTR polymorphisms.

Fine particles may cause increased pulmonary morbidity and mortality. We demonstrate with a cell culture model of the human epithelial airway wall that dendritic cells extend processes between epithelial cells through the tight junctions to collect particles in the "luminal space" and to transport them through cytoplasmic processes between epithelial cells across the epithelium or to transmigrate through the epithelium to take up particles on the epithelial surface.

Noninvasive evaluation of autonomic nervous system (ANS) and myocardial vulnerability may help determination of OSAS patients who are under high risk of malignant cardiac arrhythmias.
Rhinitis and asthma represent the manifestation of one syndrome. Our hypothesis is that in patients with symptoms of persistent rhinitis, lower airway inflammation, lower respiratory symptoms, and lung function abnormalities compatible with asthma are more frequently associated with the diagnosis of allergic rhinitis (AR) and chronic rhinosinusitis (CRS) than with nonallergic rhinitis (NAR).
The most common pathologic form of pulmonary fibrosis usually occurs from excessive deposition of extracellular matrix proteins such as collagen. The 47-kDa heat shock protein 47 (HSP47), for instance, is a collagen-specific molecular chaperone that has been shown to play a major role during the processing and/or secretion of procollagen.

Surgical resection is the standard of care for patients with resectable non-small cell lung carcinoma (NSCLC) or limited pulmonary metastases. Stereotactic radiosurgery (SRS) may offer an alternative option for high-risk patients who are not surgical candidates. We report our initial experience with SRS in the treatment of lung neoplasm.
n the traditional method of segmentectomy, the plane between segments where removal is to occur is demarcated by inflating the normal lung, while keeping the segment to be removed airless. Our method, the opposite of convention, involves inflating only the involved segment by instilling oxygen through a butterfly needle into the bronchus subtending the segment. This saves time and therefore benefits the patient.

Population-based studies on childhood community-acquired pneumonia are scarce in Latin America. Pneumococcal epidemiology is poorly defined, hence the World Health Organization recommended standardized chest radiograph interpretation to improve the approach to bacterial pneumonia. Therefore, our study aimed to estimate the burden of pneumonia in hospitalized children.
We tested whether NICU teams trained in benchmarking and quality improvement would change practices and improve rates of survival without bronchopulmonary dysplasia in inborn neonates with birth weights of <1250 g.

Very low birthweight (VLBW) infants who had prolonged oxygen dependence due to chronic respiratory problems, typically neonatal chronic lung disease (CLD), are at high risk of neurodevelopmental impairment. To assess the effect of CLD on neonatal auditory function we studied brainstem auditory evoked response (BAER) in VLBW infants who suffered CLD but no other major perinatal complications or problems.

Patients with sleep apnea are susceptible to postoperative airway compromise and respiratory dysfunction, necessitating the restriction of opioids and sedatives during their perioperative care. Dexmedetomidine is a short-acting, potent, selective alpha-2 adrenoceptor agonist with unique analgesic, sedative, and anesthesia-sparing properties; that is void of significant cardio-respiratory depressant activity at recommended clinical doses.
