PURPOSE To characterize modified triaxial microwave antennas configured to produce short ablation zones. MATERIALS AND METHODS Fifty single-antenna and 27 paired-antenna hepatic ablations were performed in domestic swine (N = 11) with 17-gauge gas-cooled modified triaxial antennas powered at 65 W from a 2.45-GHz generator. Single-antenna ablations were performed at 2 (n = 16), 5 (n = 21), and...

Genetic linkage maps play fundamental roles in understanding genome structure, explaining genome formation events during evolution, and discovering the genetic bases of important traits. A high-density cotton (Gossypium spp.) genetic map was developed using representative sets of simple sequence repeat (SSR) and the first public set of single nucleotide polymorphism (SNP) markers to genotype 18...

A comprehensive investigation was carried out on n-type ZnO nanowires for studying the temperature dependence of the piezotronic effect from 77 to 300 K. In general, lowering the temperature results in a largely enhanced piezotronic effect. The experimental results show that the behaviors can be divided into three groups depending on the carrier doping level or conductivity of the ZnO nanowires...

The aim of our study was to assess the efficacy and safety of topical timolol maleate combined with oral propranolol for nasus externus infantile hemangiomas. Between March 2012 and May 2014, propranolol was given orally to 17 infants with proliferating hemangiomas in a dose of 1.0-1.5 mg/kg/day in our department and dipped topically a small amount of 0.5% timolol maleate eye drops with medical...

The microstructure of segregated carbon in silicon oxycarbide (SiOC), hot-pressed at T = 1600 °C and p = 50 MPa, has been investigated by VIS Raman spectroscopy (λ = 514 nm) within the temperature range 25-1000 °C in air. The occurrence of the G, D' and D bands at 1590, 1620 and 1350 cm-1, together with a lateral crystal size La < 10 nm and an average distance between lattice defects LD ≈ 8 nm,...

Trusses used for roof support in coal mines are constructed of two grouted bolts installed at opposing forty-five degree angles into the roof and a cross member that ties the angled bolts together. The load on the cross member is vertical, which is transverse to the longitudinal axis, and therefore the cross member is loaded in the weakest direction. Laboratory tests were conducted to determine...

Recombinant human growth hormone (hGH) was given for 6 months or longer to 68 patients with GH deficiency, 6 with Turner's syndrome and 5 with achondroplasia, during 1986-1994 in a prospective study. The total weekly administered dose of GH was 0.6 u/kg. By random sampling, 29 of 68 GH deficient patients (42.6%) received twice weekly (2 iw) intramuscular (im) injections, 17 (25%) received ...

OBJECTIVE To determine whether plasma N-terminal proatrial natriuretic peptide (NT-proANP) concentration could predict the outcome (survival duration) of cats with cardiomyopathy (CM). DESIGN Case-control study. ANIMALS 51 cats with CM (25 with and 26 without congestive heart failure [CHF]) and 17 healthy cats. PROCEDURES Cats were thoroughly examined and assigned to 1 of 3 groups (contro...

Au-Ta2O5-SiO2-Si capacitors were studied in order to investigate their dielectric characteristics and reliability. Tantalum pentoxide thin films on Si were prepared by two methods (RF sputtering of Ta in Ar + O2 and thermal oxidation of tantalum layer on Si, with two thicknesses 50 nm and 17 nm). Films were subjected to post deposition oxygen annealing at 900° C for 30 min. The leakage current ...

We reviewed the growth characteristics of American boys and girls from published studies, including age at takeoff, age at peak height velocity, peak height velocity, duration of puberty, and the magnitude of the pubertal contribution to adult height. Age at takeoff is highly variable and sex-dependent. The mean takeoff age in children growing at an average rate is approximately 11 years in boy...
