Acoustofluidics 20: Applications in acoustic trapping.

This part of the Acoustofluidics tutorial series reviews applications in acoustic trapping of micron-sized particles and cells in microfluidic systems. Acoustic trapping enables non-invasive and non-contact immobilisation of cells and particles in microfluidic systems. Acoustic trapping has been used for reducing the time needed to create 3D cell clusters, enhance particle-based bioassays and faci

Nuclear expression of Glycogen synthase kinase-3 beta and lack of membranous beta-catenin is correlated with poor survival in colon cancer

Dysregulation of Wnt/beta-catenin signaling is a hallmark of colon cancer. Glycogen synthase kinase-3 beta (GSK-3 beta) can be a positive regulator of survival and proliferation of cultured colon cancer cell but its role in clinical colon cancer is unknown. Our objectives were to evaluate the role of GSK-3 beta in colon cancer. A tumor tissue microarray of primary colon cancers and metastases was

Low BRAF and NRAS expression levels are associated with clinical benefit from DTIC therapy and prognosis in metastatic melanoma

Metastatic melanoma is characterized by a poor response to chemotherapy. Furthermore, there is a lack of established predictive and prognostic markers. In this single institution study, we correlated mutation status and expression levels of BRAF and NRAS to dacarbazine (DTIC) treatment response as well as progression-free and overall survival in a cohort of 85 patients diagnosed with advanced mela

Sexual Knowledge in Patients With a Myocardial Infarction and Their Partners.

BACKGROUND:: Sexual health and sexual activity are important elements of an individual's well-being. For couples, this topic is often affected after a myocardial infarction (MI). It has become increasingly clear that, after an MI, patients are insufficiently educated on how to resume normal sexual activity. However, sufficient data on the general knowledge that patients and partners have about sex

Recurrent EWSR1-CREB3L1 Gene Fusions in Sclerosing Epithelioid Fibrosarcoma.

Sclerosing epithelioid fibrosarcoma (SEF) and low-grade fibromyxoid sarcoma (LGFMS) are 2 distinct types of sarcoma, with a subset of cases showing overlapping morphologic and immunohistochemical features. LGFMS is characterized by expression of the MUC4 protein, and about 90% of cases display a distinctive FUS-CREB3L2 gene fusion. In addition, SEF is often MUC4 positive, but is genetically less w

Idiopathic normal pressure hydrocephalus: cerebral perfusion measured with pCASL before and repeatedly after CSF removal.

Pseudo-continuous arterial spin labeling (pCASL) measurements were performed in 20 patients with idiopathic normal pressure hydrocephalus (iNPH) to investigate whether cerebral blood flow (CBF) increases during the first 24 hours after a cerebrospinal fluid tap test (CSF TT). Five pCASL magnetic resonance imaging (MRI) scans were performed. Two scans were performed before removal of 40 mL CSF, and

Distal tephrochronology in volcanic regions: Challenges and insights from Kamchatkan lake sediments

Kamchatka is one of the world's most active volcanic regions and has hosted many explosive eruptions during the Holocene. These eruptions had the potential to disperse tephra over wide areas, forming time-synchronous markers wherever those tephras are found. Recent research in Kamchatka has begun to focus on the geochemical analysis of individual glass shards in order to characterise tephra layers

Genetic association study of QT interval highlights role for calcium signaling pathways in myocardial repolarization.

The QT interval, an electrocardiographic measure reflecting myocardial repolarization, is a heritable trait. QT prolongation is a risk factor for ventricular arrhythmias and sudden cardiac death (SCD) and could indicate the presence of the potentially lethal mendelian long-QT syndrome (LQTS). Using a genome-wide association and replication study in up to 100,000 individuals, we identified 35 commo

Quantitative C2H2 measurements in sooty flames using mid-infrared polarization spectroscopy

Quantitative measurements of acetylene (C2H2) molecules as a combustion intermediate species in a series of rich premixed C2H4/air flames were non-intrusively performed, spatially resolved, using mid-infrared polarization spectroscopy (IRPS), by probing its fundamental ro-vibrational transitions. The flat sooty C2H4/air premixed flames with different equivalence ratios varying from 1.25 to 2.50 we

Laser-induced plasma in methane and dimethyl ether for flame ignition and combustion diagnostics

In this paper we report the investigation of the laser-induced breakdown and ignition behaviour of methane/air and dimethyl ether (DME)/air mixtures. Moreover, the optical emission from the induced plasma is utilized for determining the mixture composition quantitatively by means of laser-induced breakdown spectroscopy (LIBS). To the best of the authors' knowledge, LIBS and laser ignition of DME h

Late cerebral ischaemia after subarachnoid haemorrhage: Is cerebrovascular receptor upregulation the mechanism behind?

Late cerebral ischaemia after subarachnoid haemorrhage (SAH) carries high morbidity and mortality because of reduced cerebral blood flow (CBF) and subsequent cerebral ischaemia. This is associated with upregulation of contractile receptors in cerebral artery smooth muscles via the activation of intracellular signalling. In addition, delayed cerebral ischaemia after SAH is associated with inflammat

Numerical modelling of flow pattern for high swirling flows

This work focuses on the interaction of two coaxial swirling jets. High swirl burners are suitable for lean flames and produce low emissions. Computational Fluid Dynamics has been used to study the isothermal behaviour of two confined jets whose setup and operating conditions are those of the benchmark of Roback and Johnson. Numerical model is a Total Variation Diminishing and PISO is used to pres

Releasing Mother's Burdens: Child Abandonment and Retrieval in Madrid, 1890-1935

Abstract in UndeterminedIn nineteenth-century Europe, the foundling hospital grew beyond its traditional purpose of mitigating the shame of unwed mothers by also permitting widows, widowers, and poor married couples to abandon their children there temporarily. In the Foundling Hospital of Madrid (fhm), this new short-term abandonment could be completely anonymous due to the implementation of a whe

The A9 dopamine neuron component in grafts of ventral mesencephalon is an important determinant for recovery of motor function in a rat model of Parkinson's disease

Grafts of foetal ventral mesencephalon, used in cell replacement therapy for Parkinson's disease, are known to contain a mix of dopamine neuronal subtypes including the A9 neurons of the substantia nigra and the A10 neurons of the ventral tegmental area. However, the relative importance of these subtypes for functional repair of the brain affected by Parkinson's disease has not been studied thorou

Phase Behavior and Coassembly of DNA and Lysozyme in Dilute Aqueous Mixtures: A Model Investigation of DNA-Protein Interactions

Results from an experimental investigation of the phase behavior of an aqueous system of DNA from salmon testes and the protein lysozyme arc presented. At very low concentrations of either or both of the macromolecular components, wormlike assemblies with a width of the order of 10 nm are formed. There are strong indications that direct interactions between the protein units are instrumental both

A long-term follow-up of clinical response and regional cerebral blood flow changes in depressed patients treated with ECT.

Depression is the leading cause of disability worldwide and electroconvulsive therapy (ECT) is the most potent therapy. We investigated the clinical response and regional cerebral blood flow changes in depressed in patients treated with (ECT) in a repeated longitudinal study. Method: Forty-nine patients (21 men and 28 women) with a mean age 61 years underwent ECT. Forty-one patients grading improv

Cardiovascular disease in Adult Life after Childhood Cancer in Scandinavia: A population-based cohort study of 32,308 one-year survivors

The lifetime risk for cardiovascular disease in a large cohort of childhood cancer survivors has not been fully assessed. In a retrospective population-based cohort study predicated on comprehensive national health registers, we identified a cohort of 32,308 one-year survivors of cancer diagnosed before the age of 20 in the five Nordic countries between the start of cancer registration in the 1940
