NURR1 in Parkinson disease-from pathogenesis to therapeutic potential.

In Parkinson disease (PD), affected midbrain dopamine (DA) neurons lose specific dopaminergic properties before the neurons die. How the phenotype of DA neurons is normally established and the ways in which pathology affects the maintenance of cell identity are, therefore, important considerations. Orphan nuclear receptor NURR1 (NURR1, also known as NR4A2) is involved in the differentiation of mid

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

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

Sodium Triflate Decreases Interaggregate Repulsion and Induces Phase Separation in Cationic Micelles

Dodecyltrimethylammonium triflate (DTATf) micelles possess lower degree of counterion dissociation (a), lower hydration, and higher packing of monomers than other micelles of similar structure. Addition of sodium triflate ([NaTf] > 0.05 M) to DTATf solutions promotes phase separation. This phenomenon is commonly observed in oppositely charged surfactant mixtures, but it is rare for ionic surfactan

Do surface active parenteral formulations cause inflammation?

Local irritation and inflammation at the site of administration is a common side effect following administration of parenteral formulations. Biological effects of surface (interfacial) activity in solutions are less well investigated than effects caused by other physico-chemical parameters such as pH and osmolality. The interfacial activity in different systems, including human plasma, typical amp

cAMP-elevation mediated by β-adrenergic stimulation inhibits salt-inducible kinase (SIK) 3 activity in adipocytes.

Salt-inducible kinase (SIK) 3 is a virtually unstudied, ubiquitously expressed serine/threonine kinase, belonging to the AMP-activated protein kinase (AMPK)-related family of kinases, all of which are regulated by LKB1 phosphorylation of a threonine residue in their activation (T)-loops. Findings in adrenal cells have revealed a role for cAMP in the regulation of SIK1, and recent findings suggest

Crack tip transformation zones in austenitic stainless steel

Crack tip conditions in SUS 304 austenitic stainless steel are studied using a constitutive model in which the martensitic phase transformation is an integral part. The phase transformation occurring in the crack tip region gives rise to fracture toughening of the material whereby the resistance against crack initiation, as well as the macroscopic material response are strongly altered by the pres

Combined GW and dynamical mean-field theory: Dynamical screening effects in transition metal oxides

We present the first dynamical implementation of the combined GW and dynamical mean-field scheme ("GW + DMFT") for first-principles calculations of the electronic properties of correlated materials. The application to the ternary transition metal oxide SrVO3 demonstrates that this scheme inherits the virtues of its two parent theories: a good description of the local low-energy correlation physics

A comprehensive analysis of the Streptococcus pyogenes and human plasma protein interaction network.

Streptococcus pyogenes is a major human bacterial pathogen responsible for severe and invasive disease associated with high mortality rates. The bacterium interacts with several human blood plasma proteins and clarifying these interactions and their biological consequences will help to explain the progression from mild to severe infections. In this study, we used a combination of mass spectrometry

Not on the edge The syntax and pragmatics of clause-initial negation in Swedish

The possibility of topicalizing sentential negation is severely restricted in the Germanic V2-languages. In this paper, we show that negative preposing was more frequent and less restricted in earlier stages of Swedish: approx. 8 % of all occurrences of negation are clause initial in Old Swedish, compared to less than 0.5 % in present day Swedish. We propose that this change in frequency can be tr

Testosterone in prostate cancer: the Bethesda consensus.

What's known on the subject? and What does the study add? Androgen stimulation of prostate cancer (PCa) cells has been the basis for extensive studies evaluating the role of androgen in PCa but the diagnostic measurement of androgen as well as androgen values that potentially influence prognosis are unclear in patients with PCa. The 50 ng/dL threshold has been questioned as a result of reports ind

Vemurafenib Synergizes with Nutlin-3 to Deplete Survivin and Suppresses Melanoma Viability and Tumor Growth

Purpose: For patients with advanced melanoma, primary and secondary resistance to selective BRAF inhibition remains one of the most critically compelling challenges. One rationale argues that novel biologically informed strategies are needed to maximally cripple melanoma cells up front before compensatory mechanisms emerge. As p53 is uncommonly mutated in melanoma, restoration of its function repr

Visual mutual assessment of size in male Lyssomanes viridis jumping spider contests

Numerous animals are known to assess the resource holding potential of their opponents using conventional signals and other correlates of resource holding potential. Although body and weapon size generally correlate with resource holding potential and are often presumed to be visually evaluated in animal contests, no one has demonstrated visual assessment of opponent size while controlling for all

Thermostable glycoside hydrolases in Biorefining

Glycoside hydrolases, which are responsible for the degradation of the major fraction of biomass, the polymeric carbohydrates in starch and lignocellulose, are predicted to gain increasing roles as catalysts in biorefining applications in the future bioeconomy. In this context, thermostable variants will be important, as the recalcitrance of these biomass-components to degradation often motivates

FACS binding assay for analysing GDNF interactions.

Glial cell-line derived neurotrophic factor (GDNF) is a secreted protein with great therapeutic potential. However, in order to analyse the interactions between GDNF and its receptors, researchers have been mostly dependent of radioactive binding assays. We developed a FACS-based binding assay for GDNF as an alternative to current methods. We demonstrated that the FACS-based assay using TGW cells
