PURPOSE: This paper proposes a method for analyzing the first-order speckle statistics of nonlinear contrast-enhanced ultrasound images from tumors. METHODS: Contrast signal intensity is modeled as a compound distribution of exponential probability density functions with a gamma weighting function. The gamma probability weighting function serves as an approximation for log-normally distributed flow velocities in a vascular network. The model was applied to sub-harmonic bolus-injection images acquired from a mouse breast cancer xenograft model treated with murine version bevacizumab...

PURPOSE: To accurately measure the beam filter profiles from a variety of CT scanner models and to provide reference data for Monte Carlo simulations of CT scanners. METHODS: This study proposed a new method to measure CT beam filter profiles using a linear-array x-ray detector (X-Scan 0.8f3-512; Detection Technology Inc., Espoo, Finland) under gantry rotation mode. A robust geometrical calibration approach was developed to determine key geometrical parameters by considering the x-ray focal spot location relative to the linear-array detector and the gantry's angular increment at each acquisition point...

Full scan mode of liquid chromatography-mass spectrometry equipped with an electrospray ionization source offers a chance on global detection of complicated components; however, the scan mode carries significant challenges in rapidly capturing information of analysts. Sodiation-based in-source collision was proposed here, as a technique for rapid detecting untargeted analytes in full scan analysis, which was based on the stability of sodium adducts and the nonselectivity of in-source collision. Then the technique was applied to profile of angular-type pyranocoumarins (APs) in Radix Peucedani, with full scan analysis performed at two specific in-source collision energy: a high energy 50 V that is tolerated by the sodium adducts of APs, and a low energy 10 V, at which abundant adducts were offered...

OBJECTIVE: To investigate the effect of motor cortex stimulation (MCS) on central poststroke pain (CPSP) and the outcome predictors associated with medium- to long-term results. MATERIALS AND METHODS: This is a retrospective review of 16 CPSP patients treated with MCS with a mean follow-up of 28.2 months. The pain intensity was assessed based on the visual analogue scale (VAS) before surgery and at various follow-up visits. An effective outcome was determined to be at least 40% pain relief...

OBJECTIVE: To calculate the prevalence of vocal fold paralysis (VFP) in preterm (<37 weeks of gestation) infants at a single neonatal intensive care unit (NICU) and identify risk factors for the development of VFP. STUDY DESIGN: This is a case control study of all surviving preterm infants admitted to the NICU at Children's Hospital of Wisconsin from 2006 to 2012, comparing those with and without VFP. Multivariate analysis was performed to identify significant risk factors for VFP...

OBJECTIVE: Postnatal growth failure is common after preterm birth, in particular for infants born at ⩽28 weeks' gestation, but it is unknown if growth-to-term equivalent age has improved over the years as neonatal intensive care in general, and infant nutrition in particular, have improved. The objective of the study was to evaluate anthropometric trends at NICU discharge for infants born at ⩽28 weeks' gestation using a large national database. STUDY DESIGN: Analysis of growth in weight, length, head circumference and body mass index (kg m(2)) in 23 005 infants born in 1997 to 2012 who survived to neonatal intensive care unit discharge at ⩽41 weeks' postmenstrual age...

Background Intensive care unit survivors face many physical and psychological difficulties during their recovery following discharge from hospital. These difficulties can significantly affect their quality of life. Healthcare providers and survivors' families often do not understand what recovery means in this population, which may affect the support provided. Aim To consider the potential of the biographical method in helping to create stories that illustrate recovery in intensive care survivors and other populations...

: Iceland is a volcanic island in the North Atlantic Ocean with maritime climate. In spite of moist climate, large areas are with limited vegetation cover where >40% of Iceland is classified with considerable to very severe erosion and 21% of Iceland is volcanic sandy deserts. Not only do natural emissions from these sources influenced by strong winds affect regional air quality in Iceland ("Reykjavik haze"), but dust particles are transported over the Atlantic ocean and Arctic Ocean >1000 km at times...

OBJECTIVES: To establish a system for patient dosimetry audit and setting of Local Diagnostic Reference Levels (LDRLs) for Nuclear Medicine (NM) CT. METHODS: Computed Radiological Information System (CRIS) data were matched with NM paper records which provided the body region and dose mode for NMCT carried out at a large UK hospital. It was necessary to divide data in terms of the NM examination type, body region and dose mode. The mean and standard deviation Dose Length Products (DLPs) for common NMCT examinations were then calculated and compared to the proposed National DRLs (NDRLs)...

Realization of devices with enhanced stretchability and waterproof properties will significantly expand the reach of electronics. To this end, we herein fabricate an elastic transparent conductor that comprises silver nanowires (AgNWs) on a hydroxylated polydimethylsiloxane (PDMS) substrate covered by polyurethane urea (PUU), which is fully compatible with both materials. Carboxylic acid groups of PUU was designed to form hydrogen bonds with the carbonyl groups of poly(vinylpyrrolidone) on the AgNW surface, resulting in an enhanced affinity of AgNWs for PUU...

BACKGROUND: Nicotinic acid and nonivamide are often applied topically during capillary blood collection to induce vasodilation. These molecules may have an influence on immune effector cell activity in nearby tissues. This study investigates whether the induction of flushing by nicotinic acid and nonivamide causes an inflammatory response that influences the composition of immune cells present in a capillary blood sample. METHODS: Females aged between 18 and 30 years old provided capillary blood samples...

BACKGROUND: Despite few studies, a monitoring of a neuromuscular blockade with a train of four (TOF) is recommended in intensive care unit (ICU). Our objective was to compare the results of ulnar and facial TOF measurements with an overall clinical assessment for neuromuscular blockade in ICU patients treated with recommended doses of atracurium or cisatracurium, including patients with acute respiratory disease syndrome (ARDS). METHODS: We prospectively included in two ICUs 119 patients, 94 with ARDS, who required a neuromuscular blockade for more than 24 h...

A significant increase in carbapenemase-producing Klebsiella pneumoniae (CP-Kp) bacteraemias has been observed worldwide. The objective of the present work was to study the risk factors and predictors of mortality of CP-Kp bacteraemias among critically ill patients. During a 4-year period (2012-3015), a matched 1:2 case-control study was conducted. Klebsiella pneumoniae was identified by Vitek 2 technology. Antibiotic susceptibility was performed by the agar disc diffusion method and Etest. The presence of the bla KPC, bla VIM and bla NDM genes was confirmed by polymerase chain reaction (PCR)...

The photophysics and photochemistry of 4-hydroxybenzophenone (4HOBP) are interesting because they can give some insight into the behavior of humic material. Here we show that 4HOBP has a number of fluorescence peaks: (i) an intense one at excitation/emission wavelengths Ex/Em ∼ 200-230/280-370 nm, likely due to an excitation transition from S0 to S5 or S6, followed by S2 → S0 in emission (Sn denotes the singlet states of 4HOBP); (ii) a minor peak at Ex/Em ∼ 270-300/320-360 nm (S0 → S2 in absorption and S2 → S0 in emission), and (iii) very interesting signals in the typical emission region of humic substances, most notably at Ex/Em ∼ 200-220/400-500 nm and Ex/Em ∼ 260-280/400-470 nm (in both cases the emission corresponded to an S1 → S0 transition)...
