R-I Milos, L B Fritz, C Schueller-Weidekamm
Impingement syndrome of the ankle is a clinical diagnosis caused posttraumatically by overuse due to repetitive mechanical loading or the presence of predisposing anatomical variants. Ankle impingement syndrome is characterized by chronic pain and limited range of movement caused by mechanical compression of bony or soft tissues within the joint compartments. Ankle impingement syndrome is classified according to the various anatomical locations around the tibiotalar joint as anterior, anterolateral, anteromedial, posterior or posteromedial...

Hydrogen sulfide (H2S) is produced endogenously in vivo and has multiple effects on signaling pathways and cell function. Mitochondria can be both an H2S source and sink, and many of the biological effects of H2S relate to its interactions with mitochondria. However, the significance of mitochondrial H2S is uncertain, in part due to the difficulty of assessing changes in its concentration in vivo. While a number of fluorescent H2S probes have been developed these are best suited to cells in culture and cannot be used in vivo...

Psychosis in Alzheimer's disease (AD+P) represents a distinct clinical and neurobiological AD phenotype and is associated with more rapid cognitive decline, higher rates of abnormal behaviors, and increased caregiver burden compared with AD without psychosis. On a molecular level, AD+P is associated with greater reductions in the protein kalirin, a guanine exchange factor which has also been linked to the psychotic disease, schizophrenia. In this study, we sought to determine the molecular and behavioral consequences of kalirin reduction in APPswe/PSEN1dE9 mice...

Quantum emitters in two dimensional materials are promising candidates for studies of light-matter interaction and next generation, integrated on-chip quantum nanophotonics. However, realization of integrated nanophotonic systems requires coupling of emitters to optical cavities and resonators. In this work, we demonstrate hybrid systems in which quantum emitters in 2D hexagonal boron nitride (hBN) are deterministically coupled to high quality plasmonic nanocavity arrays. The plasmonic nanoparticle arrays offer a high quality, low loss cavity in the same spectral range as the quantum emitters in hBN...

Severe form of haemophilia in women is an extremely rare condition. Owing to the rarity of the disease there are no precise recommendations concerning the optimal management of pregnancy and delivery in these patients. We are reporting the clinical course and management of a 30-year-old woman with a severe form of haemophilia A (factor VIII <1 IU/dl) during her first pregnancy and delivery. Antepartum, she was treated on demand by FVIII concentrate and she delivered at 37 weeks of gestation by cesarean section...

The precise role of the human primary motor cortex in walking is unknown. Our previous study showed that the primary motor cortex may contribute to specific requirements of walking (i.e., maintaining a constant movement frequency and bilaterally coordinating the feet). Because aging can impair (i) the ability to fulfill the aforementioned requirements and (ii) corticomuscular communication, we hypothesized that aging would impair the motoneuronal recruitment by the primary motor cortex during bilateral cyclical movements...

The Exxon Valdez oil spill occurred in March 1989 in Prince William Sound, Alaska, and was one of the worst environmental disasters on record in the United States. Despite long-term data collection over the nearly three decades since the spill, tremendous uncertainty remains as to how significantly the spill affected fishery resources. Pacific herring (Clupea pallasii) and some wild Pacific salmon populations (Oncorhynchus spp.) in Prince William Sound declined in the early 1990s, and have not returned to the population sizes observed in the 1980s...

OBJECTIVE: Plasma concentrations of B-type natriuretic peptide (BNP) and troponin are often measured for diagnostic purposes when patients are admitted with heart failure, but their prognostic value when measured soon after admission is uncertain. We aimed to investigate the added prognostic value of admission measurements of BNP and troponins in patients with acute heart failure. METHODS AND RESULTS: Multivariable prognostic models for death or any worsening heart failure (WHF) or rehospitalization for WHF by 30 days, 30-day death or rehospitalization for WHF, and 90-day mortality were constructed using baseline data from the Value of Endothelin Receptor Inhibition with Tezosentan in Acute heart failure Studies (VERITAS) including BNP and troponin I...

Variants in the TTN gene have been associated with distal myopathies and other distinctive phenotypes involving skeletal and cardiac muscle. Through whole-exome sequencing we identified a novel stop-gain variant (c.107635C>T, p.(Gln35879Ter)) in the TTN gene, coding a part of the M-line of titin, in 14 patients with autosomal recessive distal myopathy and Serbian ancestry. All patients share a common 1 Mb core haplotype associated with c.107635C>T, suggesting a founder variant. In compound heterozygotes, nine other TTN variants were identified: four stop-gain, three frameshift, one missense and one splice donor variant...

BACKGROUND: Sleep apnea is common in patients with atrial fibrillation, but the effect of the cardioversion of atrial fibrillation to sinus rhythm on central and obstructive apneas is mainly unknown. The primary aim of the study was to analyze the association between cardioversion of atrial fibrillation and sleep apneas, to investigate whether obstructive or central sleep apneas are reduced following cardioversion. A secondary objective was to study the effect on sleep quality. METHODS: Twenty-three patients with atrial fibrillation were investigated using overnight polysomnography, including esophagus pressure monitoring and ECG, before and after the cardioversion of persistent atrial fibrillation...

REVIEW
Dan Davidi, Ron Milo
Enzyme kinetics are fundamental to an understanding of cellular metabolism and for crafting synthetic biology applications. For decades, enzyme characterization has been based on in vitro enzyme assays. However, kinetic parameters are only available for <10% of reactions, and this data scarcity limits the predictive power of metabolic models. Here we review recent studies that leverage quantitative proteomics to gain insight into in vivo enzyme kinetics. We discuss findings on the relationship between in vivo and in vitro enzyme catalysis and show how proteomics can be used to characterize the efficiency of enzyme utilization across conditions...

The exosome is a large molecular machine involved in RNA degradation and processing. Here we address how the trimeric Rrp4 cap enhances the activity of the archaeal enzyme complex. Using methyl-TROSY NMR methods we identified a 50-Å long RNA binding path on each Rrp4 protomer. We show that the Rrp4 cap can thus simultaneously recruit three substrates, one of which is degraded in the core while the others are positioned for subsequent degradation rounds. The local interaction energy between the substrate and the Rrp4-exosome increases from the periphery of the complex toward the active sites...

Exceptionally small and well-defined copper (Cu) and cuprite (Cu2O) nanoparticles (NPs) are synthesized by the reaction of mesitylcopper(I) with either H2 or air, respectively. In the presence of substoichiometric quantities of ligands, namely, stearic or di(octyl)phosphinic acid (0.1-0.2 equiv vs Cu), ultrasmall nanoparticles are prepared with diameters as low as ∼2 nm, soluble in a range of solvents. The solutions of Cu NPs undergo quantitative oxidation, on exposure to air, to form Cu2O NPs. The Cu2O NPs can be reduced back to Cu(0) NPs using accessible temperatures and low pressures of hydrogen (135 °C, 3 bar H2)...

Poised enhancers marked by H3K27me3 in pluripotent stem cells have been implicated in the establishment of somatic expression programs during embryonic stem cell (ESC) differentiation. However, the functional relevance and mechanism of action of poised enhancers remain unknown. Using CRISPR/Cas9 technology to engineer precise genetic deletions, we demonstrate that poised enhancers are necessary for the induction of major anterior neural regulators. Interestingly, circularized chromosome conformation capture sequencing (4C-seq) shows that poised enhancers already establish physical interactions with their target genes in ESCs in a polycomb repressive complex 2 (PRC2)-dependent manner...

BACKGROUND: Seizure outcome following surgery in pharmacoresistant temporal lobe epilepsy patients with normal magnetic resonance imaging and normal or non-specific histopathology is not sufficiently presented in the literature. METHODS: In a retrospective design, we reviewed data of 263 patients who had undergone temporal lobe epilepsy surgery and identified 26 (9.9%) who met the inclusion criteria. Seizure outcomes were determined at 2-year follow-up. Potential predictors of Engel class I (satisfactory outcome) were identified by logistic regression analyses...

Although bipolar nerve cuff electrodes (NCEs) are used in clinical neurostimulation therapies (e.g., epilepsy, obstructive sleep apnea), the use of this electrode as part of a closed-up controlled system is very limited. The literature points to high noise content (i.e., poor signal-to-noise ratio, SNR) as the primary reason for not using bipolar NCEs to record neural activity. In fact, over the past several decades, the pseudo-tripolar NCEs, the symmetric configuration of this electrode array (i.e., electrically-shorted side contacts) makes it very difficult to obtain directional information from the recorded neural activity (efferent vs...
