Isolated aggregates of lymphoid cells in the inner bronchial wall in asthma patients.

Here, we report findings in volunteers with bronchial asthma. Biopsies were obtained from the inner bronchial wall before and a short time again after segmental allergen provocation. In most of the baseline biopsies and in all evaluable biopsies after segmental allergen provocation, the follicular lymphoid tissue was detected by immunohistochemistry in the epithelium of these asthmatic patients. The basic occurrence of the tertiary lymphoid tissue in the bronchial mucosa of mild asthmatics was unexpected an...

Bronchial hyper-responsiveness: a technical update.

Bronchial hyper-responsiveness (BHR) is often regarded as a 'hallmark' of asthma, and bronchoprovocation testing is frequently performed to support a diagnosis of asthma. The European Respiratory Society (ERS) and American Thoracic Society (ATS) have recently updated their technical standards and guidelines for performing methacholine challenge testing (MCT), the most commonly performed clinical test of BHR.

Activation of Group 2 innate lymphoid cells after allergen challenge in asthmatics.

Group 2 innate lymphoid cells (ILC2) are effective producers of IL-5 and IL-13 during allergic inflammation and bridge the innate and adaptive immune response. ILC2 are increased in asthmatics compared to healthy controls. So far human data describing their phenotype during acute allergic inflammation in the lung is incomplete.

Magnesium and calcium reduce severity of spatial memory impairments in kainate mouse model of mesial temporal lobe epilepsy.

Calcium and magnesium are divalent multipotent ions playing a major role in metabolism, excitability and neuroglial plasticity. Because of these multiple properties, their deficits induce complex brain processes leading to acute or even lasting disorders in excitability and neural networks. These ions are usually prescribed in clinical contexts of neuronal hyperexcitability such as preeclampsia and chronic stress. Our aim was to evaluate whether magnesium at 20 mg / kg and calcium at 100 mg / kg could impro...

Intrapartum Magnesium Sulphate is Associated with Neuroprotection in Growth Restricted Fetuses.

Intrapartum magnesium sulphate administration is recommended for fetal neuroprotection in women with imminent very preterm birth. However, previous studies have not included or separately analyzed the outcomes of pregnancies with fetal growth restriction that were treated with intrapartum magnesium sulphate.

Augmented Pla2g4c/Ptgs2/Hpgds axis in bronchial smooth muscle tissues of experimental asthma.

Augmented smooth muscle contractility of the airways is one of the causes of airway hyperresponsiveness in asthmatics. However, the mechanism of the altered properties of airway smooth muscle cells is not well understood.

Augmentation of curved tip of left-sided double-lumen tubes to reduce right bronchial misplacement: A randomized controlled trial.

During intubation with a blind technique, a left-sided double-lumen tube (DLT) can be misdirected into the right bronchus even though its curved tip of the bronchial lumen turns to the left. This right bronchial misplacement may be associated with the tip angle of DLTs. We thus performed a randomized trial to test the hypothesis that the DLT with an acute tip angle enters the right bronchus less frequently than the tube with an obtuse tip angle.

Magnesium in Hemodialysis Patients: A New Understanding of the Old Problem.

Despite the prognostic significance of mineral and bone disorders in patients undergoing hemodialysis, very few studies have focused on magnesium metabolism in this population. Nephrologists have paid much attention to hypermagnesemia, which is sometimes caused by magnesium administration, but the clinical implication of low magnesium has been largely overlooked. Recently, several cohort studies have reported that lower serum magnesium levels are associated with an increased risk of all-cause and cardiovasc...

Mechanical behavior of in vivo degraded second generation resorbable magnesium scaffolds (RMS).

Resorbable magnesium scaffolds are used for the treatment of atherosclerotic coronary vascular disease and furthermore, for vascular restoration therapy. Recently, the first-in-man clinical studies with Magmaris showed promising results regarding the target lesion failure as well as vasomotion properties after 12 and 24 month. The consistency of in vivo degraded magnesium alloys in a cardiovascular environment is qualitatively described in literature, but only little has been disclosed about the actual chan...

Cat ownership is associated with increased asthma prevalence and dog ownership with decreased spirometry values.

The association between pet ownership and the development of allergic and respiratory diseases has been the aim of several studies, however, the effects of exposure in adults remain uncertain. The aims of the present study were to investigate the prevalence of asthma and lung function status among dog and cat owners. This cross-sectional study was performed at two universities with students and workers who were allocated into 3 groups according to pet ownership in the previous year: cat owners, dog owners, ...

Spontaneous coronary artery dissection treated with magnesium-made bioresorbable scaffold: 1-Year angiographic and optical coherence tomography follow-up.

A young woman admitted with a diagnosis of NSTE-ACS underwent coronary angiography which showed LAD spontaneous coronary artery dissection treated with magnesium-made bioresorbable scaffold. We report 1-year angiographic and OCT findings.

Indices of nonspecific bronchial reactivity in severe asthma phenotype determination in schoolchildren.

Introduction: Severe asthma phenotype is characterized by peculiarities of inflammatory process in the airways and consequently hypersensitivity and bronchial lability. The aim: The study aims at determining the diagnostic value of bronchial lability indices in identifying severe bronchial asthma phenotype compared to the moderate variant of disease in schoolchildren.

Prostaglandin E decrease in induced sputum of hypersensitive asthmatics during oral challenge with aspirin.

A special regulatory role for prostaglandin E (PGE ) has been postulated in Nonsteroidal anti-inflammatory drugs (NSAIDs)-exacerbated respiratory disease (NERD).

Anti-inflammatory action of HO-1/CO in human bronchial epithelium in response to cationic polypeptide challenge.

Carbon monoxide (CO) is an anti-inflammatory gaseous molecule produced endogenously by heme oxygenases (HOs) HO-1 and HO-2. However, the mechanisms underlying the anti-inflammatory effects of CO in the human bronchial epithelium are still not fully understood. In this study, the cationic peptide poly-l-arginine (PLA) was utilized to induce bronchial epithelial damage and subsequent pro-inflammatory cytokine release in the human bronchial epithelial cell line 16HBE14o-. Expression of both HO-1 and HO-2 after...

Bronchoscopic local steroid spray to prevent bronchial tuberculosis-induced cicatricial bronchial stenosis: A case series.

Cicatricial bronchial stenosis or obstruction occurring in the healing process of endobronchial tuberculosis (ET) is a problematic complication of tuberculous airway lesions. Prevention by internal medical treatment is desired.

Magnesium sulfate inhibits binding of lipopolysaccharide to THP-1 cells by reducing expression of cluster of differentiation 14.

We investigated effects of magnesium sulfate (MgSO) on modulating lipopolysaccharide (LPS)-macrophage binding and cluster of differentiation 14 (CD14) expression. Flow cytometry data revealed that the mean levels of LPS-macrophage binding and membrane-bound CD14 expression (mCD14) in differentiated THP-1 cells (a human monocytic cell line) treated with LPS plus MgSO (the LPS + M group) decreased by 28.2% and 25.3% compared with those THP-1 cells treated with LPS only (the LPS group) (P 

Magnesium status and supplementation influence vitamin D status and metabolism: results from a randomized trial.

Previous in vitro and in vivo studies indicate that enzymes that synthesize and metabolize vitamin D are magnesium dependent. Recent observational studies found that magnesium intake significantly interacted with vitamin D in relation to vitamin D status and risk of mortality. According to NHANES, 79% of US adults do not meet their Recommended Dietary Allowance of magnesium.

Allergic Airway Sensitization Impairs Anti-Bacterial IgG Antibody Responses During Bacterial Respiratory Infections.

Mycoplasma pneumoniae (Mpn), an atypical human pathogen, has been associated with asthma initiation and exacerbation. Asthmatics have been reported to have higher carriage rates of Mpn compared to non-asthmatics, and are at greater risk for invasive respiratory infections.

The Basophil Activation Test reduces the need for a food challenge test in children suspected of IgE-mediated cow's milk allergy.

The gold standard for the diagnosis of cow's milk allergy is the Double-Blind Placebo-Controlled Food Challenge (DBPCFC) test. However, disadvantages of the DBPCFC are the potential risk of anaphylactic reactions, the time consuming procedure and high costs.

Bronchial Asthma and Bronchial Hyperresponsiveness and Their Characteristics in Patients with Common Variable Immunodeficiency.

Common variable immunodeficiency (CVID) is one of the most frequent primary immunodeficiencies and is characterized by disturbed immunoglobulin production and dysregulation of the immune system. Results of previous studies suggest a higher prevalence of bronchial asthma (BA) in CVID patients than in the general population. We initiated this study to evaluate lung functions and identify risk factors for BA and bronchial hyperresponsiveness (BHR) in patients with CVID.
