A generalized mean-squared displacement from inelastic fixed window scans of incoherent neutron scattering as a model-free indicator of anomalous diffusion confinement

Elastic fixed window scans of incoherent neutron scattering are an established and frequently employed method to study dynamical changes, usually over a broad temperature range or during a process such as a conformational change in the sample. In particular, the apparent mean-squared displacement can be extracted via a model-free analysis based on a solid physical interpretation as an effective am

Quality of Chest Compressions Differs over Time between Advanced and Basic Life Support

Purpose: According to guideline recommendations, chest compressions (CC) during cardiopulmonary resuscitation (CPR) should be performed at a rate of 100 - 120 per minute, with a CC fraction (CCF) of ≥80%. The aim of this work is to explore whether CC quality differs between advanced life support (ALS) and basic life support (BLS) performed by two rescuers. Method: Cardiopulmonary resuscitation was

Endogenous expression mapping of malignant melanoma by mass spectrometry imaging

BACKGROUND: Currently, only a limited number of molecular biomarkers for malignant melanoma exist. This is the case for both diagnosing the disease, staging, and efficiently measuring the response to therapy by tracing the progression of disease development and drug impact. There is a great need to identify novel landmarks of disease progression and alterations.METHODS: Matrix-assisted laser desor

Cell density dependent uptake of chylomicron remnants in rat hepatocyte monolaayers. Effects of compactin and mevalonic acid.

In rat hepatocytes cultured in lipoprotein-deficient serum, the uptake and degradation of chylomicron remnant cholesteryl ester per mg cell protein varies inversely with cell density. Compactin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme-A reductase, stimulates the uptake at all cell densities. Mevalonic acid, on the other hand, can suppress a significant part of the remnant up

A simple method to account for off-nadir scattering in the NOAA/NASA Pathfinder AVHRR Land Data Set

The radiometric distortion of reflected radiation received by the NOAA AVHRR sensor is brought on by the effects of viewing and solar illumination geometry, as well as atmospheric effects. This may lead to a gross underestimation of bioproductivity or crop yield from models which use high temporal resolution NOAA AVHRR data as an input. Accordingly, a simple angular correction method is presented

Diagnosis of acute dysphonia

In clinical practice it may be difficult to evaluate the cause of acute dysphonia and aphonia. With the aim of elucidating the aetiology, diagnosis and management of patients with acute voice disorder, we have studied different populations with acute laryngitis and psychogenic voice disorder (PVD). The results indicate that bacterial infection is common only in patients with acute laryngitis (65%)
