BACKGROUND In an experimental model, variable and intermittent contact force (CF) resulted in a significant decrease in lesion volume. In humans, variability of CF during pulmonary vein isolation has not been characterized. METHODS AND RESULTS In 20 consecutive patients undergoing CF-guided circumferential pulmonary vein isolation, 914 radiofrequency applications (530 in sinus rhythm and 384 ...

The strain-dependent survival of cystic fibrosis (CF) knockout mice has been used to map a modifier of CF, Cfm1, in mice and, subsequently, in humans. To identify additional modifiers of the CF phenotype, in this study, the survival of F2 CF mice derived from a cross between congenic C57BL/6J CF and BALB/cJ CF heterozygotes was followed up to 12 wk of age. A genome-wide linkage scan completed i...

Background:Cystic Fibrosis (CF) is a systemic disease affecting extra pulmonary dysfunction as a result of CF-related lung disease. Because of lack of enough studies in this field and utilization of TDE in this field, we aimed to evaluate t...

We studied how physiological properties of cerebellar climbing fiber (CF) to Purkinje cell (PC) synapses change during developmental transition from multiple to mono CF innervation onto each PC. From P3 to P6, differences in the strengths of multiple CFs became larger. Around P10, each PC was either monoinnervated by one strong CF (CF-mono) or multiply innervated by one strong CF (CF-multi-S) p...

to compare potential of two organic materials including sewage sludge (ss) and municipal solid wastecompost (msw) on micronutrients entry to soil, a research was conducted as split-plot arrangement basedon randomized complete block design with three replications in research field of sari agriculturaluniversity. main-plot (fertilizer treatments) included 20 and 40 ton/ha ss, 20 and 40 ton/ha ss ...

The tomato resistance genes Cf-4 and Cf-9 confer specific, hypersensitive response-associated recognition of Cladosporium carrying the avirulence genes Avr4 and Avr9, respectively. Cf-4 and Cf-9 encode type I transmembrane proteins with extracellular leucine-rich repeats (LRRs). Compared with Cf-9, Cf-4 lacks two LRRs and differs in 78 amino acid residues. To investigate the relevance of these ...

In this paper, we achieve the general solution and the generalized Hyers-UlamRassias stability for the quadratic type functional equation f(x+ y + 2cz) + f(x+ y − 2cz) + cf(2x) + cf(2y) = 2[f(x+ y) + cf(x+ z) + cf(x− z) + cf(y + z) + cf(y − z)] for fixed integers c with c 6= 0,±1, by using the fixed point alternative.
