Sensitized photochemical CO2 reduction by hetero-Pacman compounds linking a Re(I) tricarbonyl with a porphyrin unit.

The hetero-Pacman architecture places two different metal coordination sites in close proximity, which can support efficient energy and/or electron transfer and allow for cooperative activation of small molecules. Herein, we present the synthesis of dyads consisting of a porphyrin unit as photosensitizer and a rhenium unit as catalytically active site, which are held together by the rigid xanthene backbone. Mononuclear [(NN)Re(CO)3(Cl)] complexes for CO2 reduction where NN represents a bidentate diimine lig...

Buprenorphine for the treatment of posttraumatic stress disorder.

The core pharmacological treatment of Post-Traumatic Stress Disorder (PTSD) is selective serotonin reuptake inhibitors (SSRIs), although remission is only around 30% with them. Many patients will self-treat with opioids and due to the opiate system involvement in dysphoric mood and anxiety/stress responses, it is likely that antagonism of the kappa opioid receptor (KOR) system represents a potential target for treatment of PTSD. The aim of this study is to compare response of PTSD symptoms when antagonizing...

Tumor mutational burden (TMB) standardization initiatives: Recommendations for consistent TMB assessment in clinical samples to guide immunotherapy treatment decisions.

Characterization of tumors utilizing next-generation sequencing methods, including assessment of the number of somatic mutations (tumor mutational burden [TMB]), is currently at the forefront of the field of personalized medicine. Recent clinical studies have associated high TMB with improved patient response rates and survival benefit from immune checkpoint inhibitors; hence, TMB is emerging as a biomarker of response for these immunotherapy agents. However, variability in current methods for TMB estimatio...

Chromosome territories and the global regulation of the genome.

Spatial positioning is a fundamental principle governing nuclear processes. Chromatin is organized as a hierarchy from nucleosomes to Mbp chromatin domains (CD) or topologically associating domains (TADs) to higher level compartments culminating in chromosome territories (CT). Microscopic and sequencing techniques have substantiated chromatin organization as a critical factor regulating gene expression. For example, enhancers loop back to interact with their target genes almost exclusively within TADs, dist...

Biocatalytic strategies towards 4+2 cycloadditions.

Long sought after [4+2] cyclases have sprouted up in numerous biosynthetic pathways in recent years, raising hopes for biocatalytic solutions to cycloaddition catalysis, an important problem in chemical synthesis. In a few cases, detailed pictures of the inner workings of these catalysts have emerged, but intense efforts to gain deeper understanding are underway by means of crystallography and computational modelling. This review aims to shed light on the catalytic strategies that this highly diverse family...

Impulsiveness as a predictor of topiramate response for cocaine use disorder.

Pulse sequence considerations for quantification of pyruvate-to-lactate conversion k in hyperpolarized C imaging.

Hyperpolarized C MRI takes advantage of the unprecedented 50 000-fold signal-to-noise ratio enhancement to interrogate cancer metabolism in patients and animals. It can measure the pyruvate-to-lactate conversion rate, k , a metabolic biomarker of cancer aggressiveness and progression. Therefore, it is crucial to evaluate k reliably. In this study, three sequence components and parameters that modulate k estimation were identified and investigated in model simulations and through in vivo animal studies usin...

The Extended Treatment Window's Impact on Emergency Systems of Care for Acute Stroke.

The window for acute ischemic stroke treatment was previously limited to 4.5 hours for intravenous tissue plasminogen activator and to 6 hours for thrombectomy. Recent studies using advanced imaging selection expand this window for select patients up to 24 hours from last known well. These studies directly affect emergency stroke management, including pre-hospital triage and emergency department management of suspected stroke patients. This narrative review summarizes the data expanding the treatment window...

Highly Active Cobalt-Based Electrocatalysts with Facile Incorporation of Dopants for Oxygen Evolution Reaction.

In-situ formation of electroactive cobalt species for the oxygen evolution reaction is simply achieved by applying an anodic bias to a commercially available cobalt precursor and Nafion binder mixture coated on a glassy carbon electrode. Without needing energy-intensive materials preparation steps and noble metals, a low overpotential of 322 mV at 10.2 mA/cm2 and a high current density of more than 300 mA/cm2 at 1.7 V were obtained in 1 M KOH. An operando electrochemical Raman spectroscopy study confirmed t...

Fascin in lamellipodia contributes to cell elasticity by controlling the orientation of filamentous actin.

Fascin, an actin bundling protein, is present in the filopodia and lamellipodia of growth cones. However, few studies have examined lamellipodial fascin because it is difficult to observe. In this study, we evaluated lamellipodial fascin. We visualized the actin meshwork of lamellipodia in live growth cones by super-resolution microscopy. Fascin was co-localized with the actin meshwork in lamellipodia. Ser39 of fascin is a well-known phosphorylation site that controls the binding of fascin to actin filament...

Template-Free Synthesis of Highly B-Oriented MFI-Type Zeolite Thin Films by Seeded Secondary Growth.

Highly b-oriented, closely packed, MFI zeolite films are prepared on seeded stainless-steel plates using organic template-free, secondary growth solutions, containing aluminum sulfate as a crystallization agent. The number of a-oriented twin crystals is significantly reduced, and even eliminated, simply by restricting the pH value of the secondary growth solution to the narrow range of 11.1-11.3. Values of pH can be adjusted through the controlled addition of (NH ) SO or H SO to secondary growth solutions o...
