Current noninvasive imaging methods are not sufficiently reliable for accurate detection of malignancy in most solitary pulmonary nodules (SPNs). Positron emission tomography (PET) using 18-fluorodeoxyglucose (FDG), showing increased FDG uptake and retention in malignant cells, has proved useful to differentiate malignant from benign tissue and could, therefore, contribute to the evaluation of ...

Increased arterial wall tension stimulates growth and remodeling of arteries, but little is known about the effects of decreased wall tension, despite its developmental and pathological significance. Consequently, we cuffed 1 carotid artery in rabbits with a portion of the contralateral artery to off-load circumferential wall tension. The model produced rapid and extensive atrophy of the cuffed...

Investigating the piezotronic effect in p-type piezoelectric semiconductor is critical for developing a complete piezotronic theory and designing/fabricating novel piezotronic applications with more complex functionality. Using a low temperature solution method, we were able to produce ultralong (up to 60 μm in length) Sb doped p-type ZnO nanowires on both rigid and flexible substrates. For the...

OBJECTIVE To describe the 5-year change in visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) areas. RESEARCH DESIGN AND METHODS Absolute change in VAT and SAT measured by abdominal computed tomography scans has been obtained at a 5-year interval from African Americans (n = 389) and Hispanic Americans (n = 844), aged 20-69 years, in 10-year age-groups. RESULTS Mean 5-year incre...

Eight distinct hydroxy nitrates are stable products of the first step in the atmospheric oxidation of isoprene by OH. The subsequent chemical fate of these molecules affects global and regional production of ozone and aerosol as well as the location of nitrogen deposition. We synthesized and purified 3 of the 8 isoprene hydroxy nitrate isomers: (E/Z)-2-methyl-4-nitrooxybut-2-ene-1-ol and 3-meth...

We have previously shown that B6 congenic mice with a New Zealand Black chromosome 1 (c1) 96-100 cM interval produce anti-nuclear Abs and that at least two additional genetic loci are required to convert this subclinical disease to fatal glomerulonephritis in mice with a c1 70-100 cM interval (c1(70-100)). Here we show that the number of T follicular helper and IL-21-, IFN-γ-, and IL-17-secreti...

OBJECTIVE To evaluate the effectiveness of liquid nitrogen (LN(2)) vapor (indirect contact method) for the storage of human semen. DESIGN Experimental study. SETTING University hospital-based fertility center. PATIENT(S) We evaluated 150 patients with normal sperm parameters. INTERVENTION(S) Human semen (N = 120) was mixed with Semen Freezing Medium, divided into two groups, frozen, and...

In this comparative, cross-sectional study, we evaluated 55 patients with epilepsy on chronic use of antiepileptic drugs (AED); [(38 females and 17 males, 35 +/- 6 years (25 to 47)] and compared to 24 healthy subjects (17 females/7 males). Laboratorial evaluation of bone and mineral metabolism including measurements of bone specific alkaline phosphatase (BALP) and carboxyterminal telopeptide of...
