We investigate media which exhibits epsilon-near-zero (ENZ) behavior while simultaneously sustaining stopped light energy bands which contain multiple points of zero group velocity (ZGV). This allows the merging of state-of-the-art phenomena that was hitherto attainable in media that demonstrated these traits separately. Specifically, we demonstrate the existence of Ferrell-Berreman (FB) modes within frequency bands bounded by points of ZGV with the goal to improve the coupling efficiency and localization of light in the media...

BACKGROUND: Physical activity promotion in people with Chronic Obstructive Pulmonary Disease (COPD) is focus of research and public health. Patient-centred interventions like counselling are promising approaches to help patients reducing sedentary behaviour. Aim of the present study is to investigate if a physical activity counselling program during pulmonary rehabilitation increases physical activity level in daily life in people with COPD. METHODS: A two-armed, single blind randomised controlled trial including 56 people with COPD will be conducted in an outpatient pulmonary rehabilitation...

Increased procoagulant activity in the alveolar compartment and uncontrolled inflammation are hallmarks of the acute respiratory distress syndrome (ARDS). Here, we investigated whether the contact phase system of coagulation is activated and may regulate inflammatory responses in human lungs. Components of the contact phase system were characterized in bronchoalveolar lavage fluids (BALF) from 54 ARDS patients and 43 controls, and their impact on cytokine/chemokine expression in human precision cut lung slices (PCLS) was assessed by a PCR array...

Lyme disease, the most commonly reported vector-borne disease in the United States, results from infection with Borrelia burgdorferi. Early clinical diagnosis of this disease is largely based on the presence of an erythematous skin lesion for individuals in high-risk regions. This, however, can be confused with other illnesses including southern tick-associated rash illness (STARI), an illness that lacks a defined etiological agent or laboratory diagnostic test, and is coprevalent with Lyme disease in portions of the eastern United States...

This research focuses on the difference between the Kinetic Crutch Tip (KCT) and a Standard Rubber Tip. Additionally, the effect of KCT stiffness on the crutch gait cycle and the reaction forces were investigated. This study also examined the maximum backward angle that a crutch is able to move forward without any external forces as well as the ratio of positive to negative horizontal forces were considered. The results were obtained in two ways: one by having subjects walk on the crutches and another to reduce the variability of human walking by measuring the resulting motion only using weights attached to the crutch tip...

Gamma-hydroxybutyric acid (GHB) can be used as a knock-out drug in drug facilitated crime (DFC). Due to its rapid metabolism and resulting narrow detection window, uncovering GHB use in DFC still constitutes a problem. In this experiment we determined the GHB and GHB-β-O-glucuronide (GHB-Gluc) concentrations in hair samples after single and chronic GHB exposures. Hair samples of three narcoleptic patients therapeutically taking sodium oxybate (GHB-sodium-salt) were collected. Patients 1 (P1) and 2 (P2) took the medication for nine and six years, respectively...

The average intake of the essential trace element selenium (Se) is below the recommendation in most European countries, possibly causing sub-optimal expression of selenoproteins. It is still unclear how a suboptimal Se status may affect health. To mimic this situation, mice were fed one of three physiologically relevant amounts of Se. We focused on the liver, the organ most sensitive to changes in the Se supply indicated by hepatic glutathione peroxidase activity. In addition, liver is the main organ for synthesis of methyl groups and glutathione via one-carbon metabolism...

Comprehensive multiplatform analysis of 80 uveal melanomas (UM) identifies four molecularly distinct, clinically relevant subtypes: two associated with poor-prognosis monosomy 3 (M3) and two with better-prognosis disomy 3 (D3). We show that BAP1 loss follows M3 occurrence and correlates with a global DNA methylation state that is distinct from D3-UM. Poor-prognosis M3-UM divide into subsets with divergent genomic aberrations, transcriptional features, and clinical outcomes. We report change-of-function SRSF2 mutations...

With the advent of new methodologies, proteomics-based assays are increasingly used to study the efficacy of drugs on a molecular level. For these studies to be meaningful, the proteomics assays need to be sensitive, selective, accurate, and reproducible. This is often accomplished through a targeted approach, either using single or multiple reaction monitoring (SRM/MRM) or, more recently, parallel reaction monitoring (PRM). In PRM, the parallel detection of all product ions in a high-resolution mass spectrometer affords higher selectivity than SRM/MRM...

Carbon monoxide (CO) is usually recognized as a toxic gas that can be used to assess lung function in the pulmonary function laboratory. The toxicity of CO relates to its high affinity for hemoglobin and other heme molecules, producing carboxyhemoglobin (HbCO). Despite that blood HbCO levels are commonly measured in patients with CO poisoning, the clinical presentation often does not correlate with the HbCO level, and clinical improvement in the patient's condition does not correlate with HbCO clearance. In patients with CO poisoning, administration of 100% O2 is standard practice...

The P2Y12 receptor is a validated target for prevention of major adverse cardiovascular events in patients with acute coronary syndrome. The aim of this study was to compare two direct-acting, reversible P2Y12 antagonists, ACT-246475 and ticagrelor, in a rat thrombosis model by simultaneous quantification of their antithrombotic efficacy and surgery-induced blood loss. Blood flow velocity was assessed in the carotid artery after FeCl3 -induced thrombus formation using a Doppler flow probe. At the same time, blood loss after surgical wounding of the spleen was quantified...

Contrary to lay conceptions, unattractive locations can under certain circumstances increase the perceived value of neighboring areas. This phenomenon is akin to a contrast effect. However, extant research on this type of contrast suffers from two limitations. First, the use of repeated measures may inflate the likelihood of observing a contrast effect. Second, there is a lack of meaningful comparisons for gauging the size of the effect. We designed three experiments to address these issues. In each, we assessed how much participants valued places located increasingly far from an unsafe housing block...

RATIONALE: It has been suggested that endothelial dysfunction caused by a decreased endothelial production of nitric oxide (NO) may contribute to the consistently observed increased risk of developing cardiovascular disease (CVD) in physically healthy patients suffering from major depression (MD). NO is a gas synthesized from Larginine (a conditionally essential amino acid) and oxygen by endothelial nitric oxide synthase (eNOS). The end products of NO production include both NO and L-citrulline...

OBJECTIVE: Intraoperative monitoring of cerebral microcirculation in patients with subarachnoid hemorrhage (SAH) may predict the postoperative neurological outcome. In this pilot study, we examined the value of a novel non-invasive real-time measurement technique to detect changes in local microcirculation. METHODS: We used the laser-Doppler spectrophotometry system "Oxygen-to-see(O2C)" in 14 patients with SAH Hunt & Hess grade 2 to 5, who underwent microsurgical clipping of cerebral aneurysms...

Although patients with indolent B-cell lymphomas have a relatively good survival rate, conventional chemotherapy is not curative. Disease courses are typically characterized by multiple relapses and progressively shorter response duration with subsequent lines of therapy. There has been an explosion of innovative targeted agents in the past years. This review discusses current knowledge on the etiology of indolent B-cell lymphomas with respect to the role of micro-organisms, auto-immune diseases, and deregulated pathways caused by mutations...

OBJECTIVES: In stable coronary artery disease (CAD), coronary revascularisation may reduce mortality of patients with a certain amount of left ventricular myocardial ischaemia. However, revascularisation does not always follow the guidance suggested by ischaemia testing. We compared outcomes in patients without ischaemia who had either revascularisation or medical treatment. DESIGN AND POPULATION: Based on registries, 1327 consecutive patients with normal myocardial perfusion scintigraphy (MPS) and 278 with fixed perfusion defects were followed for a median of 6...

BACKGROUND: Cranial irradiation is associated with long-term cognitive changes. Cerebral microbleeds (CMBs) have been identified on susceptibility-weighted MRI (SWI) in patients who have received prior cranial radiation, and serve as radiographic markers for microvascular injury thought to contribute to late cognitive decline. The relationship between CMB formation and radiation dose has not previously been quantified. METHODS: SWI was performed on 13 patients with stable WHO grade III-IV gliomas between 2 and 4 years after chemoradiotherapy to 60 Gy...
