Purpose Several models have been developed to predict nonsentinel lymph node (non-SN) status in patients with breast cancer sentinel (SN) metastasis. The purpose of our investigation was compare available a prospective, multicenter study. Patients and Methods In cohort 561 positive-SN who underwent axillary dissection, we evaluated the areas under receiver operating characteristic curves (AUCs), calibration, rates false negatives (FN), number group at low risk for non-SN calculated from nine...
Abstract The adhesion of three microorganisms ( Saccharomyces cerevisiae, Acetobacter aceti , and Moniliella pollinis ) to different materials has been studied using various supports (glass, metals, plastics), some which were treated by an Fe(III) solution. surface properties the cells characterized zeta potential index hydrophobicity; characterization involved chemical analysis (XPS) contact angle measurements. Cell suspensions in pure water at a given pH left settle on plates; latter then...
Mucocele of the appendix is a descriptive term for an abnormal mucous accumulation distending appendiceal lumen. Pseudomyxoma peritonei characterized by mucinous ascites and implants throughout abdominal cavity. Thirty-four cases mucocele seven pseudomyxoma origin on file at Armed Forces Institute Pathology were reviewed their clinical, pathologic, radiologic findings. These provided examples major findings reported in this entity. Previously unreported dependent echoes within some mucoceles...
Abstract Background Breast cancer is the first cause of death among women and its incidence doubled in last two decades. Several approaches for treatment these cancers have been developed. The axillary lymph node dissection (ALND) leads to numerous morbidity complications now advantageously replaced by biopsy sentinel node. Although this approach has strong advantages, it own limitations which are manipulation radioactive products possible anaphylactic reactions dye. As recently proposed,...
The experimental work reported here is devoted to the temporal behaviour of a mono-filamentary dielectric barrier discharge in pure argon, from 100 700 Torr. A sinusoidal voltage supply used, its frequency ranging 10 90 kHz. An anode avalanche followed by cathode streamer as well spatial stability micro-discharge clearly seen successive 3-ns snapshots visible range. Near cathode, diameter about 0.2 mm, at 400 electrical characteristics are also evaluated, particular breakdown and energy...
Abstract This work is devoted to the evaluation of efficiency a new low-temperature plasma jet driven in ambient air by dc-corona discharge inactivate adherent cells and biofilms Gram-positive bacteria. The selected microorganisms were lactic acid bacteria, Weissella confusa strain which has particularity excrete polysaccharide polymer (dextran) when sucrose present. Both treated with for different exposure times. antimicrobial was tested against 48 h-old grown or without sucrose. Bacterial...
Three models have been developed to predict four or more involved axillary lymph nodes (ALNs) in patients with breast cancer one three sentinel (SLNs). Two scores were by Chagpar et al (Louisville excluding including method of detection), and a nomogram was Katz al. The purpose our investigation compare these prospective, multicenter study.Our study cohort 536 having SLNs who underwent ALN dissection. We evaluated the area under receiver operating characteristic curve (AUC), calibration (for...
In this paper we report the experimental investigation of a pure xenon monofilamentary dielectric barrier discharge (DBD), using high voltage power supply. Stable microdischarges were achieved and studied in pressure range 100–400Torr, at frequencies between 10 40kHz. Successive 3ns exposure time snapshots clearly show how it built up. Its diameter was about 0.26mm. The current determined from measurement supply current. Compared to those argon, pulses shorter (less than 30ns, above 200Torr)...
The present paper is devoted to the 2D simulation of an Atmospheric Corona Discharge Reactor (ACDR) involving 10 pins powered by a DC high voltage and positioned 7 mm above grounded metallic plane. corona reactor periodically crossed thin mono filamentary streamers with natural repetition frequency some tens kHz. involves electro-dynamic, chemical kinetic, neutral gas hydrodynamic phenomena that influence kinetics species transformation. Each discharge stage (including primary secondary...

The VUV emissions of gaseous mixtures krypton and xenon were investigated at room temperature. For this purpose, a pulsed, brief, selective multiphotonic excitation the two lowest atomic states 5p56s configuration was achieved. A spectroscopic kinetic study performed, for first time, by comparing radiation characteristics consecutive to initially populating either metastable Xe[5p56s(3P2)] or resonant Xe[5p56s(3P1)] states. formation heteronuclear KrXe* excimers clearly shown. decay...
In the treatment of oral cavity cancer, margin status is one most critical prognostic factors. Positive margins are associated with higher local recurrence and lower survival rates. Therefore, universal goal surgical oncology to achieve microscopically clear margins. Near-infrared fluorescence guided surgery (FGS) could improve resection using fluorescent probes. αVβ6 integrin has shown great potential for cancer targeting due its overexpression in cancers. Red contrast agent IRDye 680...
