Background
Myocarditis is an inflammatory disease of the myocardium indicated by mononuclear cell infiltration. It is predominantly caused by infectious agents such as coxsackievirus B3 (CVB3). Especially in young adults, myocarditis is a major source of sudden cardiac arrest. However, its clinical course has a broad spectrum of outcomes, ranging from mild symptoms and complete recovery to cardiac dysfunction and dilated cardiomyopathy. G protein-coupled receptor 15 (GPR15) was identified as a T cell homing receptor in the context of inflammatory intestine and skin diseases. We found Gpr15 to be highly upregulated in the left ventricle (LV) 7 days after CVB3 infection in wild type (WT) mice.
Purpose
GPR15 has not been described in a cardiac context, yet. Our aim was to investigate the role of GPR15 in recruiting immune cell subsets and later in virus elimination during viral myocarditis.
Methods
Gpr15 deficient (Gpr15gfp/gfp) and WT mice were infected intraperitoneal with CVB3 to investigate the acute (6 & 7 days post infection(p.i.)) and the subacute phase (16 days p.i.) of myocarditis. To study differentially expressed genes, LV tissue was used for TaqMan analysis and RNA-sequencing. Inflammation and fibrosis were evaluated on histological level. For functional characterization, healthy and diseased mice were hemodynamically characterized 16 days p.i.. Furthermore, in vitro migration assays were used to study the interaction between GPR15 and its ligands in vitro.
Results
Infected Gpr15gfp/gfp mice exhibited higher upregulation of immune response related genes on mRNA level in the acute phase of myocarditis 7 days p.i.. For instance, Cd8a, a cytotoxic T cell marker, and Foxp3, a regulatory T cell marker, were significantly higher in infected Gpr15gfp/gfp compared to infected WT mice. Bulk RNA-sequencing confirmed that the response to virus did not decline from day 6 to 7 in infected GPR15-deficient mice as observed in infected WT mice. Subsequent gene ontology (GO) term analyses reveled enhanced chemotaxis and cytotoxic T cell-related GO terms in GPR15-deficient mice on day 7.
Among investigated T cell subsets, GPR15 was highest expressed on CD8+ T cell. Its deficiency abolished chemotaxis of T cells, especially of cytotoxic T cells, towards GPR15 ligand in vitro.
In the subacute phase of myocarditis 16 days p.i., viral persistence was observed in more than 85 % of Gpr15gfp/gfp mice. In contrast, more than 70 % of WT mice with verified viremia cleared the virus successfully. Furthermore, Gpr15gfp/gfp mice demonstrated a decreased cardiac function accompanied by increased fibrosis in comparison to WT mice.
Conclusion
Our findings indicate that despite the prolonged inflammatory response, scant virus elimination was presumably caused by decelerated recruitment of cytotoxic T cells leading to impaired outcome in the GPR15-deficient mice.

Abstract
Spin-lattice relaxation rates R1(ω,T), probed via high-field and field-cycling nuclear magnetic resonance (NMR), are used to test the validity of frequency-temperature superposition (FTS) for the reorientation dynamics in viscous liquids. For several liquids, FTS is found to apply so that master curves can be generated. The susceptibility spectra are highly similar to those obtained from depolarized light scattering (DLS) and reveal an excess wing. Where FTS works, two approaches are suggested to access the susceptibility: (i) a plot of deuteron R1(T) vs the spin-spin relaxation rate R2(T) and (ii) a plot of R1(T) vs an independently measured reference time τref(T). Using single-frequency scans, (i) allows one to extract the relaxation stretching as well as the NMR coupling constant. Surveying 26 data sets, we find Kohlrausch functions with exponents 0.39 < βK ≤ 0.67. Plots of the spin-spin relaxation rate R2─rescaled by the NMR coupling constant─as a function of temperature allow one to test how well site-specific NMR relaxations couple to a given reference process. Upon cooling of flexible molecule liquids, the site-specific dynamics is found to merge, suggesting that near Tg the molecules reorient essentially as a rigid entity. This presents a possible resolution for the much lower stretching parameters reported here at high temperatures that contrast with the ones that were reported to be universal in a recent DLS study close to Tg. Our analysis underlines that deuteron relaxation is a uniquely powerful tool to probe single-particle reorientation.

Abstract
We combine field-cycling (FC) relaxometry and molecular dynamics (MD) simulations to study the rotational and translational dynamics associated with the glassy slowdown of glycerol. The 1H NMR spin-lattice relaxation rates R1(ω) probed in the FC measurements for different isotope-labelled compounds are computed from the MD trajectories for broad frequency and temperature ranges. We find high correspondence between experiment and simulation. Concerning the rotational motion, we observe that the aliphatic and hydroxyl groups show similar correlation times but different stretching parameters, while the overall reorientation associated with the structural relaxation remains largely isotropic. Additional analysis of the simulation results reveals that transitions between different molecular configurations are slow on the time scale of the structural relaxation at least at sufficiently high temperatures, indicating that glycerol rotates at a rigid entity, but the reorientation is slower for elongated than for compact conformers. The translational contribution to R1(ω) is well described by the force-free hard sphere model. At sufficiently low frequencies, universal square-root laws provide access to the molecular diffusion coefficients. In both experiment and simulation, the time scales of the rotational and translational motions show an unusually large separation, which is at variance with the Stokes-Einstein-Debye relation. To further explore this effect, we investigate the structure and dynamics on various length scales in the simulations. We observe that a prepeak in the static structure factor S(q), which is related to a local segregation of aliphatic and hydroxyl groups, is accompanied by a peak in the correlation times τ(q) from coherent scattering functions.

Abstract
Field-Cycling (FC) NMR experiments were carried out at 1H Larmor frequencies down to about 3Hz. This could be achieved by fast switching a high polarizing magnetic field down to a low evolution field which is tilted with respect to the polarization field. Then, the low frequency Larmor precession of the nuclear spin magnetization about this evolution field is registered by means of FIDs in a high detection field. The crucial technical point of the experiment is the stabilization of the evolution field, which is achieved by compensating for temporal magnetic field fluctuations of all three spatial components. The paper reports on some other basic low field experiments such as the simultaneous measurement of the Larmor frequency and the spin-lattice relaxation time in such small fields as well as the irradiation of oscillating transversal magnetic field pulses at very low frequencies as a novel method for field calibration in low field FC NMR. The potential of low field FC is exemplified by the 1H relaxation dispersion of water at frequencies below about 2kHz stemming from the slow proton exchange process.

Abstract
The article gives a comprehensive overview of hydrogen storage in carbon nanostructures, including experimental results and theoretical calculations. Soon after the discovery of carbon nanotubes in 1991, different research groups succeeded in filling carbon nanotubes with some elements, and, therefore, the question arose of filling carbon nanotubes with hydrogen by possibly using new effects such as nano-capillarity. Subsequently, very promising experiments claiming high hydrogen storage capacities in different carbon nanostructures initiated enormous research activity. Hydrogen storage capacities have been reported that exceed the benchmark for automotive application of 6.5 wt% set by the U.S. Department of Energy. However, the experimental data obtained with different methods for various carbon nanostructures show an extreme scatter. Classical calculations based on physisorption of hydrogen molecules could not explain the high storage capacities measured at ambient temperature, and, assuming chemisorption of hydrogen atoms, hydrogen release requires temperatures too high for technical applications. Up to now, only a few calculations and experiments indicate the possibility of an intermediate binding energy. Recently, serious doubt has arisen in relation to several key experiments, causing considerable controversy. Furthermore, high hydrogen storage capacities measured for carbon nanofibers did not survive cross-checking in different laboratories. Therefore, in light of today's knowledge, it is becoming less likely that at moderate pressures around room temperature carbon nanostructures can store the amount of hydrogen required for automotive applications.

Abstract
Classification of inherited neurodegenerative diseases is increasingly based on their genetic features, which supplement, clarify, and sometimes replace the older clinical and pathologic schemata. This change has been particularly rapid and impressive for the CAG repeat disorders. In Huntington's disease, X-linked spinobulbar muscular atrophy, dentatorubropallidoluysian atrophy, and a series of autosomal dominant cerebellar atrophies, genetic advances have resolved many nosologic issues, and opened new avenues for exploration of pathogenesis. In this review, we summarize classic and current concepts in neuropathology of these CAG repeat diseases.

Abstract
Huntington's disease (HD) is an inherited neurodegenerative disorder associated with expansion of a CAG repeat in the IT15 gene. The IT15 gene is translated to a protein product termed huntingtin that contains a polyglutamine (polyGln) tract. Recent investigations indicate that the cause of HD is expansion of the polyGln tract. However, the function of huntingtin and how the expanded polyGln tract causes HD is not known. We investigate potential protein-protein interactions of huntingtin using affinity resins. Huntingtin from brain extracts is retained on calmodulin(CAM)-Sepharose in a calcium-dependent fashion. We purify rat huntingtin to apparent homogeneity using a combination of DEAE-cellulose column chromatography, ammonium sulfate precipitation, and preparative SDS/PAGE. Purified rat huntingtin does not interact with CAM directly as revealed by 125I-CAM overlay. Huntingtin forms a large CAM-containing complex of over 1,000 kDa in the presence of calcium, which partially disassociates in the absence of calcium. Furthermore, an increased amount of mutant huntingtin from HD patient brains is retained on CAM-Sepharose compared to normal huntingtin from control patient brains, and the mutant allele is preferentially retained on CAM-Sepharose in the absence of calcium. These results suggest that huntingtin interacts with other proteins including CAM and that the expansion of polyGln alters this interaction.

Abstract
A direct method for the determination of piroxicam in plasma is described. Plasma is directly injected onto the extraction column (10 mm x 2 mm I.D., packed with 40-microns Bond Elut C2) where proxicam is separated from the plasma concomitants using a solid-phase extraction procedure. Using a laboratory-made on-line column-switching system, the drug is quantitatively transferred and separated on the analytical column (15 cm x 4.6 mm I.D., Supelcosil LC18 DB, 5 microns) followed by determination using ultraviolet absorption at 331 nm. Validation of the method demonstrated a good recovery (100%), sensitivity (limit of determination 0.2 microgram/ml, based on a 20-microliters sample volume), accuracy and precision (better than 5%). The developed method has been adopted for studying the steady-state pharmacokinetics of the drug.

Abstract
Clinical and autopsy findings are reported of three cases of Addisons disease due to idiopathic dystrophy of the adrenal cortex as seen in two women, 20 and 37 years of age respectively as well as a boy of 14 years. Idiopathic dystrophy of the adrenal cortex as a cause of Addisons disease has become aware of more and more frequently for some years. Its classification as an auto-aggression disease has been made a subject for discussion. Morphological findings and immunological investigations with three own cases confirm this conception. This disease should be reminded of with regard to the problem of clinically diagnosing it and the fatal prognosis of untreated cases.

Abstract
In a female patient with a tumour of the brain stem the e.e.g. showed signs of increasing general functional disorders and additional transient high voltage monographic waves with bilateral frontal and central accentuation, which we regarded as brain stem disturbances. At the same time the authors observed a characteristic inhibition of the amplitude of brain reflexes as well as high phases of a polyphasic stimulation--response potential with stimulation of the tibial nerve. Beside these inhibition phenomena, signs of disinhibition were verified (nociceptive, trigemino-trigeminal reflex, polyphasic disinhibited brain reflex?). The photostimulation was without influence on the sensitivity of motoneurons.
