Severe iron-deficiency anemia as initial manifestation of pulmonary hemosiderosis in a child

Einstein (Säo Paulo); 16 (4), 2018
ABSTRACT Idiopathic pulmonary hemosiderosis is a potentially fatal disease that results from episodes of alveolar hemorrhage of unknown origin. The clinical spectrum is varied, and anemia may constitute the only manifestation of illness, preceding other signs and symptoms by several months. We present th...

Imbalance of γδT17/γδTreg cells in the pathogenesis of allergic asthma induced by ovalbumin

Braz. j. med. biol. res; 51 (9), 2018
We aimed to explore the imbalance between the T helper 17 γδT cells (γδT17) and the regulatory γδT cells (γδTreg) in asthmatic mice. Male Balb/c mice were randomly divided into the normal control group and the asthmatic model group. The asthmatic model group mice w...

Vitamin D3 levels and NLRP3 expression in murine models of obese asthma: association with asthma outcomes

Braz. j. med. biol. res; 51 (1), 2018
Vitamin D (25(OH)D3) is an essential nutrient that plays a role in the immune system. Serum 25(OH)D3 is found to be associated with asthma. However, the role of vitamin D in obese asthma remains unclear. Therefore, we investigated the association between vitamin D levels and asthma outcomes in a murine m...

The effects of individually ventilated cages on the respiratory systems of male and female Wistar rats from birth until adulthood

Clinics; 72 (3), 2017
OBJECTIVE: To evaluate the respiratory systems of male and female rats maintained in individually ventilated cages (IVCs) from birth until adulthood. METHODS: Female Wistar rats were housed in individually ventilated cages or conventional cages (CCs) and mated with male Wistar rats. After birth and wean...

Neutrophil elastase ameliorates matrix metalloproteinase-9 to promote lipopolysaccharide-induced acute lung injury in mice 1

Acta cir. bras; 31 (6), 2016
ABSTRACT PURPOSE: To investigate the regulatory roles of neutrophil elastase (NE) and matrix metalloproteinase-9 (MMP-9) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. METHODS: To construct LPS-induced ALI mouse models, wild-type C57BL/6 mice were administered 5.0 mg/kg of LPS t...

Stenotrophomonas maltophilia pseudo-outbreak at a University Hospital Bronchoscopy unit in Turkey

West Indian med. j; 63 (1), 2014
OBJECTIVE: Stenotrophomonas maltophilia is an opportunistic pathogen found predominantly in the enviroment and hospital setting. Invasive procedures and treatment methods, instruments used for diagnosis and irrational antibiotic use play major roles in the spread of this pathogen. The study aimed to eval...

Estudio de la respuesta inflamatoria celular através del lavado bronco alveolar en asma alérgica, por aspirina y en las alveolitis alérgica extrínseca
Bronchoalveolar lavage in the study of inflammatory cellular response in: allergic asthma, aspirin asthma, and extrinsic allergic alveolitis

La respuesta inflamatoria asmática presenta diferentes tipos de células involucradas en este proceso, tales como: linfocitos, eosinófilos. En manos experimentadas el lavado broncoalveolar (LBA) es un procedimento bien tolerado y con gran valor como herramienta para la investigación de los mecanismos ...
