Abstract Light in biological media is known as freely diffusing because interference negligible. Here, we show Anderson light localization quasi-two-dimensional protein nanostructures produced by silkworms ( Bombyx mori ). For transmission channels native silk, the flux governed a few localized modes. Relative spatial fluctuations quantities are proximal to regime. The sizes of passive cavities (smaller than single fibre) and statistics modes (decomposed from excitation at gain–loss...
Suicide is an important and potentially preventable consequence of serious mental disorders unknown etiology. Gene expression profiling technology provides unbiased approach to identifying candidate genes for disorders. Microarray studies with post-mortem prefrontal cortex (Brodmann's Area 46/10) tissue require larger sample sizes. This study poses the question: what extent are differentially expressed suicide a diagnostic specific set (bipolar disorder vs. schizophrenia) shared common...
Cecropin is a well-studied antimicrobial peptide that synthesized in fat body cells and hemocytes of insects response to hypodermic injury or bacterial infection. A 503 bp cDNA encoding for cecropin-like was isolated by employing annealing control primer (ACP)-based differential display PCR 5'-RACE with immunized Papilio xuthus larvae. The open reading frame the encoded 62-amino acid prepropeptide putative 22-residue signal peptide, 2-residue propeptide, 38-residue mature theoretical mass...
There are various treatment modalities of onychomycosis. Of these, however, oral antifungal therapies complicated by potential drug interactions and systemic effects, the surgical can result in prolonged pain. Therefore, a new, safe effective therapy is needed that improve aesthetic appearance nails.The purpose this study was to evaluate effect onychomycosis with 1,064-nm long-pulsed Nd:YAG laser.13 patients (31 toenails, 12 fingernails) received five sessions at 4-week intervals laser....
Inguinal hernia with containing the ovary presenting as a palpable groin mass is an uncommon congenital condition, and it may cause complications such strangulation, torsion, infertility. We present case of ovarian herniation into inguinal canal sonographic findings. A 15-day-old infant girl visited our hospital complaints in right groin. On physical examination, non-movable was found region, irreducible. During well-circumscribed solid small cysts found. Then, oophorectomy high ligation...
Background Currently, no ideal prosthesis is available for right ventricular outflow tract (RVOT) reconstruction in neonates and young infants. Therefore, we developed a 10-mm handmade monocusp expanded polytetrafluoroethylene (ePTFE) valved conduit report our experience. Methods A retrospective clinical review was conducted on 11 consecutive patients who underwent RVOT with ePTFE since May 2018. Six definitive Rastelli operation, five palliative ventricle-to-pulmonary artery formation. The...
In this paper, dc sourcing capability (DSC), which is a very important consideration in design of active bias circuits for power amplifiers based on bipolar technologies, will be explained. The nonlinear effect the characteristics has been analyzed with simplified using Volterra series. analysis shows that second-order distortion generated by buffer transistor can boost level RF to compensate finite DSC available absence effect. bias-level boosting due injection optimized tuning value series...
Spatial and temporal variations in the abundance biomass of heterotrophic protists their grazing impact were investigated during five cruises between July 2006 February 2009 continental shelf waters northern East China Sea (ECS). Strongly patchy distributions observed on all cruises, generally with a higher western areas affected by Changjiang River discharge. An opposite pattern was when Kuroshio onshore transport is greatest, greater eastern area. Small dinoflagellates (<20 µm) most...
Summary Various lasers have been used for the treatment of erythematotelangiectatic rosacea ( ETR ) that does not respond to systemic or topical therapy. The pulsed dye PDL s) are an effective option , and purpuragenic fluence proved be superior until now. Given purpura subsequent possible postinflammatory hyperpigmentation PIH occasionally unbearable in some patients, several studies using low nonpurpuragenic were reported. To deliver sufficient high a without generating purpura, we...
We investigated the effect of balloon pulmonary valvuloplasty (BPV) as a palliative procedure for patients with tetralogy Fallot (TOF).This was retrospective single-center study conducted between 2008 and 2014. classified into three groups according to palliation: treatment BPV (group I), Blalock-Taussig shunt II), infundibulectomy III). The growth valve (PV) annulus need transannular patching (TAP) during total correction were compared groups.Forty-eight enrolled: 31, 10, 7 in I, II, III,...
We investigated the mid-term surgical results of Fontan conversion with antiarrhythmias surgery and permanent pacemaker implantation, which were complications a previous operation. From January 1996 to November 2011, we performed in 31 260 cases (M:F = 17:14, mean age 19.0 years). The from atriopulmonary connection (APC) extracardiac conduit (ECC) was 20 patients, APC lateral tunnel 5 ECC 6. clinical outcomes improvements arrhythmias analysed. types included atrial flutter 21 fibrillation 4...
We report the results of a bicuspid expanded polytetrafluoroethylene (ePTFE) valved conduit used for right ventricular outflow tract reconstruction (RVOTR).Between November 2005 and February 2009, 12 conduits were RVOTR. The mean age weight patients 43.5 ± 46.4 months 13.4 8.6 kg. main diagnosis was tetralogy Fallot with pulmonary atresia in eight patients. most common size 18 mm. follow-up 88.0 35.9 months.There no operative late mortalities. At discharge, peak systolic pressure gradient...
The surgical management of transposition complex with aortic arch obstruction remains technically demanding due to anatomic complexity. Even in the recent era, there are centers that address this anomaly a staged strategy. This report presents our experiences one-stage repair complexes obstructions more than last 10 years. Since 2003, 19 patients great arteries (TGA, 2 patients) or double outlet right ventricle (DORV, 17 and have undergone their anomalies. mean age was 6.7 ± 2.3 days, body...
Abstract In this study, we sought predictors of mortality in children with acute myocarditis and incomplete recovery the survivor group. We classified our patients into three groups according to their outcomes at last follow-up: full was as group I, II, death III. total, 55 were enrolled study: 33 11 The initial left ventricular fractional shortening – significantly lower III (p=0.001), end-diastolic dimension z score higher II compared I (p=0.000). A multivariate analysis showed that (odds...
Duplication of the vertebral artery (VA) is a rare vascular variant. To best our knowledge, only fourteen cases have been reported with angiographic findings that they dual origin VA from ipsilateral subclavian artery. Herein, we present case duplication right which was incidentally detected by magnetic resonance (MR) angiography.A 69-year-old female patient presented headache for 30 days. She underwent brain MR imaging angiography evaluating possible intracranial cause. There as an...
Seasonal variation in species composition and abundance of fish assemblage the north coast (NC: Ayajin) central (CC: Hupo) East Sea were calculated using samples collected by trammel net during 2011-2012. A total 20 from NC 17 CC collected. Of fishes collected, dominant Glyptocephalus stelleri Careproctus rastrinus NC, Dasycottus setiger G. CC. These 2 accounted for 71.7% 81.0% number individuals CC, respectively. The species, individuals, biomass diversity indices fluctuated with seasons....
We adopted an operative technique of pulmonary valve (PV) annular enlargement with repair in tetralogy Fallot (TOF) correction to reduce postoperative regurgitation (PR) 16 years ago. Here, we have evaluated the long-term results. Between April 2000 and August 2005, 43 patients (26 men) stenosis underwent PV repair. The median age body weight at time surgery were 14 months 10.2 kg, respectively. There was no mortality. Mean PR grade discharge 0.93 ± 0.40 (none or trivial 10 patients, mild 27...
To determine the effectiveness of ethanol (EtOH) washing on porcine pulmonary artery (PA) wall decellularization using sodium dodecyl sulfate (SDS), we compared three different methods (phosphate-buffered saline [PBS], pH 9 alkali, and EtOH washing).Fresh PA walls were decellularized 0.5% SDS deoxycholate (SDC). The tissues rinsed techniques. Histological, biochemical, mechanical analyses conducted. Implantation into subcutaneous tissue rats patch implantation carotid dogs performed as...
