Treatment with αvβ3-integrin-specific 29P attenuates pressure-overload induced cardiac remodelling after transverse aortic constriction in mice.

Heart failure remains one of the largest clinical burdens globally, with little to no improvement in the development of disease-eradicating therapeutics. Integrin targeting has been used in the treatment of ocular disease and cancer, but little is known about its utility in the treatment of heart failure. Here we sought to determine whether the second generation orally available, αvβ3-specific RGD-mimetic, , was cardioprotective.

Bioorthogonal Chemical Labeling Probes Targeting Sialic Acid Isomers for -Glycan MALDI Imaging Mass Spectrometry of Tissues, Cells, and Biofluids.

Sialic acid isomers attached in either α2,3 or α2,6 linkage to glycan termini confer distinct chemical, biological, and pathological properties, but they cannot be distinguished by mass differences in traditional mass spectrometry experiments. Multiple derivatization strategies have been developed to stabilize and facilitate the analysis of sialic acid isomers and their glycoconjugate carriers by high-performance liquid chromatography, capillary electrophoresis, and mass spectrometry workflows. Herein, a set of novel derivatization schemes are described that result in the introduction of bioorthogonal click chemistry alkyne or azide groups into α2,3- and α2,8-linked sialic acids.

Heterogeneity of glycan biomarker clusters as an indicator of recurrence in pancreatic cancer.

Introduction: Outcomes following tumor resection vary dramatically among patients with pancreatic ductal adenocarcinoma (PDAC). A challenge in defining predictive biomarkers is to discern within the complex tumor tissue the specific subpopulations and relationships that drive recurrence. Multiplexed immunofluorescence is valuable for such studies when supplied with markers of relevant subpopulations and analysis methods to sort out the intra-tumor relationships that are informative of tumor behavior.

The InSight HP Penetrator (Mole) on Mars: Soil Properties Derived from the Penetration Attempts and Related Activities.

Unlabelled: The NASA InSight Lander on Mars includes the Heat Flow and Physical Properties Package HP to measure the surface heat flow of the planet. The package uses temperature sensors that would have been brought to the target depth of 3-5 m by a small penetrator, nicknamed the mole. The mole requiring friction on its hull to balance remaining recoil from its hammer mechanism did not penetrate to the targeted depth.

Suppression of Endothelial Cell FAK Expression Reduces Pancreatic Ductal Adenocarcinoma Metastasis after Gemcitabine Treatment.

Unlabelled: Despite substantial advances in the treatment of solid cancers, resistance to therapy remains a major obstacle to prolonged progression-free survival. Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive cancers, with a high level of liver metastasis. Primary PDAC is highly hypoxic, and metastases are resistant to first-line treatment, including gemcitabine.

Cardiorenal risk of celecoxib compared with naproxen or ibuprofen in arthritis patients: insights from the PRECISION trial.

Aims: Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used drugs, both prescribed and over the counter. The long-term cardiovascular safety of NSAIDs in patients with arthritis has engendered controversy. Concerns remain regarding the relative incidence and severity of adverse cardiorenal effects, particularly in arthritis patients with established cardiovascular (CV) disease or risk factors for disease as illustrated by the PRECISION (Prospective Randomized Evaluation of Celecoxib Integrated Safety vs.

Bcar1/p130Cas is essential for ventricular development and neural crest cell remodelling of the cardiac outflow tract.

Aims: The adapter protein p130Cas, encoded by the Bcar1 gene, is a key regulator of cell movement, adhesion, and cell cycle control in diverse cell types. Bcar1 constitutive knockout mice are embryonic lethal by embryonic days (E) 11.5-12.

The Zebrafish Cardiac Endothelial Cell-Roles in Development and Regeneration.

In zebrafish, the spatiotemporal development of the vascular system is well described due to its stereotypical nature. However, the cellular and molecular mechanisms orchestrating post-embryonic vascular development, the maintenance of vascular homeostasis, or how coronary vessels integrate into the growing heart are less well studied. In the context of cardiac regeneration, the central cellular mechanism by which the heart regenerates a fully functional myocardium relies on the proliferation of pre-existing cardiomyocytes; the epicardium and the endocardium are also known to play key roles in the regenerative process.

The treatment of binge eating disorder with cognitive behavior therapy and other therapies: An overview and clinical considerations.

Binge eating disorder (BED) is a public health problem in several countries. BED is commonly associated with comorbidities such as obesity, diabetes, and depression. Notwithstanding the health problems associated with BED, evidence-based treatments for BED are not widely used by healthcare professionals worldwide.

Detection of Chemotherapy-resistant Pancreatic Cancer Using a Glycan Biomarker, sTRA.

Purpose: A subset of pancreatic ductal adenocarcinomas (PDACs) is highly resistant to systemic chemotherapy, but no markers are available in clinical settings to identify this subset. We hypothesized that a glycan biomarker for PDACs called sialylated tumor-related antigen (sTRA) could be used for this purpose.

Experimental Design: We tested for differences between PDACs classified by glycan expression in multiple systems: sets of cell lines, organoids, and isogenic cell lines; primary tumors; and blood plasma from human subjects.

P130Cas/bcar1 mediates zebrafish caudal vein plexus angiogenesis.

P130CAS/BCAR1 belongs to the CAS family of adaptor proteins, with important regulatory roles in cell migration, cell cycle control, and apoptosis. Previously, we and others showed that P130CAS mediates VEGF-A and PDGF signalling in vitro, but its cardiovascular function in vivo remains relatively unexplored. We characterise here a novel deletion model of P130CAS in zebrafish.

Cognitive-behavioral therapy in the time of coronavirus: Clinician tips for working with eating disorders via telehealth when face-to-face meetings are not possible.

Objective: The coronavirus pandemic has led to a dramatically different way of working for many therapists working with eating disorders, where telehealth has suddenly become the norm. However, many clinicians feel ill equipped to deliver therapy via telehealth, while adhering to evidence-based interventions. This article draws together clinician experiences of the issues that should be attended to, and how to address them within a telehealth framework.

Dialectical behavioral therapy: an update and review of the existing treatment models adapted for adults with eating disorders.

Despite the effectiveness of CBT in reducing shape/weight concerns and dietary restraint, research suggests that patients considered recovered may still exhibit emotional difficulties related to eating disorders (EDs). Dialectical behavior therapy (DBT) has been adapted for a variety of mental disorders characterized by emotion dysregulation and, more recently, for EDs specifically. The current review found that the majority of the research studies employed one of the following three adaptations of DBT for EDs: The Stanford Model, Radically Open-DBT (RO-DBT), or Multidiagnostic ED-DBT (MED-DBT).

Improving the resilience of drinking water and wastewater utilities and emergency management agencies through collaboration.

Responding to a major disaster requires coordination and communication across all critical infrastructure sectors, including emergency management and drinking water and wastewater. This paper describes how in planning for an earthquake in the Cascadia Subduction Zone, the various bureaus in the City of Portland developed robust relationships by participating in joint exercises and events, coordinating on damage assessments and collaborating on planning efforts. The paper also describes the various tools and resources provided by the US Environmental Protection Agency to help water utilities and emergency management agencies to strengthen their relationships.

Effect of Left Ventricular Conduction Delay on All-Cause and Cardiovascular Mortality (from the PRECISION Trial).

The prognosis associated with prolonged intraventricular conduction on electrocardiogram (ECG) remains uncertain. We aimed to compare clinical outcomes of narrow versus prolonged intraventricular conduction on ECG stratified by QRS morphology and cardiovascular disease (CVD) status. A post-hoc analysis was performed of the randomized-control PRECISION trial.

Neuropilin 1 mediates epicardial activation and revascularization in the regenerating zebrafish heart.

Unlike adult mammals, zebrafish can regenerate their heart. A key mechanism for regeneration is the activation of the epicardium, leading to the establishment of a supporting scaffold for new cardiomyocytes, angiogenesis and cytokine secretion. Neuropilins are co-receptors that mediate signaling of kinase receptors for cytokines with crucial roles in zebrafish heart regeneration.

Slice-illuminated optical projection tomography.

To improve the imaging performance of optical projection tomography (OPT) in live samples, we have explored a parallelized implementation of semi-confocal line illumination and detection to discriminate against scattered photons. Slice-illuminated OPT (sl-OPT) improves reconstruction quality in scattering samples by reducing interpixel crosstalk at the cost of increased acquisition time. For in vivo imaging, this can be ameliorated through the use of compressed sensing on angularly undersampled OPT data sets.

Effect of Aspirin Coadministration on the Safety of Celecoxib, Naproxen, or Ibuprofen.

Background: The safety of nonsteroidal anti-inflammatory drug (NSAID) and aspirin coadministration is uncertain.

Objectives: The aim of this study was to compare the safety of combining NSAIDs with low-dose aspirin.

Methods: This analysis of the PRECISION (Prospective Randomized Evaluation of Celecoxib Integrated Safety Versus Ibuprofen or Naproxen) trial included 23,953 patients with osteoarthritis or rheumatoid arthritis at increased cardiovascular risk randomized to celecoxib, ibuprofen, or naproxen.

Randomised clinical trial: gastrointestinal events in arthritis patients treated with celecoxib, ibuprofen or naproxen in the PRECISION trial.
