Failure to detect hydroxyl radical (.OH)-derived spin adducts of 5,5-dimethyl-1-pyrroline N-oxide in electron spin resonance (ESR) spin trapping experiments has been offered as evidence for the lack of the endogenous capacity of stimulated human phagocytes (neutrophils, monocytes, and monocyte-derived macrophages (MDM] to generate .OH. Recent reports that 5,5-dimethyl-1-pyrroline N-oxide spin a...

Recent advancements in camera trap technology have allowed researchers to explore methodologies that are minimally invasive, and both time and cost efficient (Long et al. 2008; O’Connell et al. 2010; Gregory et al. 2014; Meek et al. 2014; Swinnen et al. 2014; Newey et al. 2015). The use of cameras for understanding the distribution and ecology of mammals is advanced; however, their utility for ...

OBJECTIVE To evaluate the high resolution computed tomography (HRCT) findings of bronchiolitis obliterans (BO) after bone marrow transplantation (BMT). MATERIALS AND METHODS During the past three years, 11 patients were diagnosed as having BO after BMT when they developed irreversible air flow obstruction, with an FEV(1) value of less than 80% of the baseline value, without any clinical evide...

Pulmonary emphysema and chronic bronchitis together are referred to under the acronym COPD. It is estimated that chronic obstructive pulmonary disease (COPD) affects approximately 6% to 15.8% of the population aged above 40 years, as the data obtained by the PLATINO study for São Paulo are generalized for the whole Brazilian population. Chronic obstructive pulmonary disease is the fifth leading...

PURPOSE To image respiratory dynamics and three-dimensional (3D) ventilation during inhalation, breath-hold, and exhalation for evaluation of obstructive lung disease using a single dose of hyperpolarized (HP) He-3 during MRI. MATERIALS AND METHODS A single 2D-3D projections inside Z encoding (PRIZE)-2D acquisition was performed that consisted of a rapid 2D radial acquisition phase during inh...

In order to simultaneously decrease the production costs of thin film silicon solar cells and obtain higher performances, the authors have studied the possibility to increase the light trapping effect within thin film silicon solar cells deposited on flexible plastic substrates. In this context, different nano-structure shapes useable for the back contacts of amorphous silicon solar cells on pl...

When studying the motion of optically trapped particles on the microsecond time scale, in low-viscosity media such as air, inertia cannot be neglected. Resolution of unusual and interesting behavior not seen in colloidal trapping experiments is possible. In an attempt to explain the phenomena we use power-spectral methods to perform a parameter study of the Brownian motion of optically trapped ...

BACKGROUND Several recent studies have suggested that 1 minus-forced expiratory volume expired in 3 seconds / forced vital capacity (1-FEV3/FVC) may be an indicator of distal airway obstruction and a promising measure to evaluate small airways dysfunction. AIMS To investigate the associations of 1-FEV3/FVC with the spirometric measures and lung volumes that assess small airways dysfunction an...

The search for materials with high thermal resistance has promising applications in thermoelectric devices and boiling crisis retardation. In this paper, we study the interfacial heat transfer between water gold, nanostructuring gold surface coating it graphene. By trapping air (or vacuum our simulations) graphene nanopatterned surface, observe a considerable increase compared to planar situati...
