Gastric cancer remains a leading cause of malignancy-related mortality. Many patients with locally advanced disease succumb despite peri-operative chemotherapy and the survival benefit of chemotherapy for advanced disease is modest, suggesting that current staging is imperfect. The role of fluorine-18-2-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in the staging of gastric cancer ...

Introduction: The development of new antiarrhythmic agents is challenging and is hampered by high attrition rate of novel drug candidates. One of the reasons for this is limited predictability of existing preclinical models for drug assessment. Cardiomyocytes (CMs) derived from disease-specific induced pluripotent stem cells (iPSC) represent a novel in ...

Estimation of time since death is one of the challenges in forensic science. There are many approaches to estimate the postmortem interval, including both physical and thanatochemistry methods. Decomposition is triggered by a process called autolysis, which induces destructive changes in the cell leading to cell death. Based on the ...

Local adaptation likely involves selection on multiple, genetically unlinked traits to increase fitness in divergent habitats. Conversely, recombination is expected to counteract local adaptation under gene flow by breaking down adaptive gene combinations. Western European populations of the salt marsh beetle Pogonus chalceus are characterized by large interpopulation variation at ...

Cough and swallow are highly coordinated reflex behaviors whose common purpose is to protect the airway. The pharynx is the common tube for air and food/liquid movement from the mouth into the thorax, has been largely overlooked, and is potentially seen as just a passive space. The thyropharyngeus muscle responds ...

Excess glutamatergic neurotransmission may contribute to excitotoxic loss of nigrostriatal neurons in Parkinson's disease (PD). Here, we determined if increasing glutamate uptake could reduce the extent of tyrosine hydroxylase (TH) loss in PD progression. The beta-lactam antibiotic, ceftriaxone, increases the expression of glutamate transporter 1 (GLT-1), a glutamate transporter that ...

We found previously that stimulation of natriuretic peptide receptor (NPR)-B by C-type natriuretic peptide (CNP) in failing rat ventricle potentiates β1-adrenoceptor (β1-AR)-mediated inotropic response to noradrenaline through cGMP-mediated inhibition of phosphodiesterase (PDE) 3, thereby enhancing cAMP-mediated signalling. Increased cAMP-mediated signalling is deleterious in chronic heart failure (HF; basis for the ...

Circulating melanoma cells (CMCs) are thought to be the foundation for metastatic disease, which makes this cancer especially lethal. Cancer cells contained in the primary tumor undergo genotypic and phenotypic changes leading to an epithelial-to-mesenchymal transition, during which numerous changes occur in signaling pathways and proteins in the cells. CMCs ...
