Fine Tuning of Surface Structures by Soft‐Template Electropolymerization

open access: yesChemNanoMat, EarlyView.
Nanotubes are formed by soft‐template electropolymerization in solvent of low water‐solubility but especially using one of the two tested stereoisomers of benzodithiophene and using an interfacially more active electrolyte with long alkyl chains (tetrahexylammonium perchlorate).

Metabolic Changes in Living Human Lymphoma Cells Intervening NAD+ Metabolism as Revealed by NAD(P)H‐Fluorescence Lifetime Imaging and Para‐Hydrogen‐Induced Polarization NMR

open access: yesCytometry Part A, EarlyView.
ABSTRACT Proliferating cells have a sustained high demand for regeneration of electron acceptors as nicotinamide dinucleotide (phosphate) (NAD(P)+/NAD(P)H) is involved in a number of critical redox reactions within cells. However, their analysis in living cells is still challenging.

Detection of a Single Microdose of Testosterone and Recombinant EPO in Healthy Volunteers

open access: yesDrug Testing and Analysis, EarlyView.
Exogenous T was detected with IRMS regardless of T/E elevation—high serum T indicative for IRMS. rhEPO was detected in urine for 72 h in ITP and CP, and Tasso showed less sensitivity than previous DBS devices tested. ABSTRACT Doping with testosterone (T) and erythropoietin (EPO) in low doses (micro‐doping) is a challenge to detect.

Biosynthesis and Identification of Clenbuterol Metabolites in Urine and In Vitro Microsome Incubation Samples Using UHPLC‐Q‐Exactive Orbitrap Mass Spectrometry: A Comparison Between Human and Bovine Metabolism

open access: yesDrug Testing and Analysis, EarlyView.
Clenbuterol metabolism was studied in bovine and human urine using LC‐Q‐Exactive‐Orbitrap MS; eight metabolites were identified in human and bovine samples as well as a novel N‐methylated form. Four urinary metabolites specific to cattle were detected and identified.

Squamate ventricular cardiomyocytes: Ploidy, proliferation, and heart muscle cell size in the leopard gecko (Eublepharis macularius)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Ideology and utopia by Karl Mannheim

open access: yesRevista Sem Aspas, 2013
This work aims to introduce the concepts of ideology and utopia by Karl Mannheim, setting them in an epistemological and sociological perspective and the consequences which, according to Mannheim, both involve to the notion of "all truth", in which must ...

Exact solution to standard model hydrodynamic cosmological perturbation theory and its implications for acoustic oscillations

open access: yesPhysics Letters B
We present an exact solution to standard model cosmological perturbation theory in a matter-dominated, adiabatic, hydrodynamic era. The solution is in the form of hypergeometric functions.

Why Young People With Eating Disorder Symptoms Do Not Seek Help—Exploring Barriers to Help‐Seeking

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Rates of help‐seeking and treatment uptake are low in eating disorders. Delayed initiation of treatment has a negative impact on prognosis and treatment outcome and leads to a higher burden on the healthcare system. The aim of this study was to explore factors associated with help‐seeking and their interactions in a large sample of ...
