OBJECTIVE The usual procedure for obtaining material for histological analysis for the diagnosis of peripheral carcinoma of the lung is transbronchial forceps biopsy (TBB). Not widely spread is acquiring samples for cytological examination by transbronchial catheter aspiration (TBCA). Data were retrospectively collected to determine the diagnostic sensitivity of TBCA in comparison with TBB conc...

BACKGROUND Firemaster® 550 (FM550) is commonly added to residential furniture to reduce its flammability. Recent toxicological evidence suggests that FM550 may be endocrine disrupting and obesogenic. OBJECTIVES Our objectives were to develop methods to assess exposure to FM550 in human populations and to identify potential routes of exposure. METHODS Using mass spectrometry methods, we deve...

OBJECTIVE To determine the diagnostic yield of EBUS guided TBB performed in routine practice with flexible bronchoscopy and under moderate sedation in ambulatory and hospitalized patients. METHODS Bronchoscopy was performed under standard conditions in ambulatory and hospitalised patients. Bronchoscopically invisible peripheral pulmonary lesions were located with 20 MHZ-EBUS-probe and transbr...

BACKGROUND Due to the small amount of alveolar tissue in transbronchial biopsy (TBB) by forceps, the diagnosis of diffuse, parenchymal lung diseases (DPLD) is inherently problematic, with an overall low yield. The use of cryotechnique in bronchoscopy, including TBB by cryoprobe, has revealed new opportunities in the endoscopical diagnosis of malignant and non-malignant lung diseases. METHODS ...

AIM To evaluate the frequency of complications in bronchoscopy from data compiled between 1/2/2002 to 1/2/2003. MATERIALS AND METHODS Nineteen Italian centres of thoracic endoscopy participated in the study, for a total of 20,986 bronchoscopies (FBS), including 10,658 explorative bronchoscopies (EB) (50.79%), 5,520 bronchial biopsies (BB) (26.30%), 1,660 transbronchial biopsies (TBB) (7.91%),...

An experimental conditioner (Exp), which was an aqueous solution of 10% ascorbic acid and 5% ferric chloride, was prepared in this study. This study evaluated the effect of Exp on the microtensile bond strength between a self-curing resin and dentin after long-term water immersion. Flat human dentin surfaces were sequentially pretreated with 40% phosphoric acid, 10% sodium hypochlorite, and Exp...

Keetia leucantha is a West African tree used in traditional medicine to treat several diseases among which parasitic infections. The dichloromethane extract of leaves was previously shown to possess growth-inhibitory activities on Plasmodium falciparum, Trypanosoma brucei brucei and Leishmania mexicana mexicana with low or no cytotoxicity (>100 μg/ml on human normal fibroblasts) (Bero et al. 20...

Stewart in 1983 (Can J Physiol Pharmacol 1983: 61: 1444) reintroduced plasma buffer base under the name "strong ion difference" (SID). Buffer base was originally introduced by Singer and Hastings in 1948 (Medicine (Baltimore) 1948: 27: 223). Plasma buffer base, which is practically equal to the sum of bicarbonate and albuminate anions, may be increased due to an excess of base or due to an incr...

The purpose of this study was to examine the feasibility of a conditioner for treating enamel and dentin simultaneously for MMA-TBB resin bonding. Various phosphoric acid solutions containing copper salts were prepared and used as conditioners before bonding MMA-TBB resin to bovine teeth. Their effects on the surface morphology and bonding were studied by scanning electron microscopy and tensil...

The habitat selection choices that individuals make in response to thermal environments influence both survival and reproduction. Importantly, the way that organisms behaviorally respond to thermal environments depends on the availability and juxtaposition of sites affording tolerable or preferred microclimates. Although, ground nesting birds are especially susceptible to heat extremes across m...
