Electric charges are conserved. The same would be expected to hold for magnetic charges, yet magnetic monopoles have never been observed. It is therefore surprising that the laws of nonequilibrium thermodynamics, combined with Maxwell's equations, suggest that colloidal particles heated or cooled in certain polar or paramagnetic solvents may behave as if they carry an electric/magnetic charge. Here, we present numerical simulations that show that the field distribution around a pair of such heated/cooled colloidal particles agrees quantitatively with the theoretical predictions for a pair of oppositely charged electric or magnetic monopoles...

Rationale: Ventricular arrhythmias remain the leading cause of death in patients suffering myocardial ischemia. Myeloperoxidase (MPO), a heme-enzyme released by polymorphonuclear neutrophils, accumulates within ischemic myocardium and has been linked to adverse left ventricular remodeling. Objective: To reveal the role of MPO for the development of ventricular arrhythmias. Methods and Results: In different murine models of myocardial ischemia MPO deficiency profoundly decreased vulnerability for ventricular tachycardia (VT) upon programmed right ventricular and burst stimulation and spontaneously as assessed by ECG telemetry following isoproterenol injection...

Human mitochondrial DNA haplogroup U is among the initial maternal founders in Southwest Asia and Europe and one that best indicates matrilineal genetic continuity between late Pleistocene hunter-gatherer groups and present-day populations of Europe. While most haplogroup U subclades are older than 30 thousand years, the comparatively recent coalescence time of the extant variation of haplogroup U7 (~16-19 thousand years ago) suggests that its current distribution is the consequence of more recent dispersal events, despite its wide geographical range across Europe, the Near East and South Asia...

BACKGROUND: A single self-rated health (SRH) question is associated with health outcomes, but agreement between SRH and physician-rated patient health (PRPH) has been poorly studied. We studied patient and physician reasoning for health ratings and the role played by patient lifestyle and objective health measures in the congruence between SRH and PRPH. METHODS: Surveys of established family medicine patients and their physicians, and medical record review at 4 offices...

We evaluated our phosphonium-based fluorescent probes for selective staining of mitochondria. Currently used probes for monitoring mitochondrial membrane potential show varying degrees of interference with cell metabolism, photo-induced damage and probe binding. Here presented probes are characterised by highly efficient cellular uptake and specific accumulation in mitochondria. Fluorescent detection of the probes was accomplished using flow cytometry and confocal microscopy imaging of yeast and mammalian cells...

Cellular components sequestered by autophagosomes during macroautophagy must be degraded and their components recycled in order to maintain homeostasis. To this end cells orchestrate the fusion of autophagosomes with lysosomes, degradative organelles that are rich in hydrolases. Most of the lysosomal enzymes function optimally at low pH, and products of macromolecular catabolism are cotransported with protons across the autolysosomal membrane. These functions are facilitated by the ability of lysosomes to pump protons inward, acidifying their lumen...

Pectus excavatum is one of the most common congenital chest wall deformities. The degree of sternal depression, which may result in compression of the right heart by the chest wall, is variable. While typically asymptomatic, there are various symptoms that can result from severe pectus excavatum. We report on a patient with severe pectus excavatum leading to dynamic obstruction of the right ventricular outflow tract in the seated position.

Aortic root thrombus is an uncommon complication of continuous-flow left ventricular assist devices (LVAD). We present the case of a 71-year-old man with ischemic cardiomyopathy who underwent destination therapy HeartMate II LVAD placement. Eighteen months later, he presented with a cerebrovascular accident followed by myocardial infarction. Transesophageal echocardiography revealed an aortic root thrombus spanning the left and noncoronary cusps and obliterating the left main coronary artery. We discuss the incidence, risk factors, and management of aortic root thrombus in LVAD patients...

Polyphenols are antioxidant molecules found in many foods including nuts, fruits, vegetables, chocolate, wine, and tea. Polyphenols have antimicrobial, anti-inflammatory, and antineoplastic properties. Recent studies suggest that tea polyphenols may be used for reducing sebum production in the skin and for treatment of acne vulgaris. This review examines the evidence for use of topically and orally ingested tea polyphenols against sebum production and for acne treatment and prevention. The PubMed database was searched for studies on tea polyphenols, sebum secretion, and acne vulgaris...

Presence of aflatoxin M1 (AFM1) in milk should be continuously controlled in order to protect the population from risks associated with its proven toxicity and carcinogenicity. During recent years, there has been an increase in demand for development of sensitive, accurate, simple and fast method which is reliable for detection of AFM1 at low concentrations found in milk samples. For that purpose, enzyme linked immunosorbent asssay (ELISA), high performance liquid chromatography with fluorescence detector (HPLC-FLD) and high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) were optimized and validated in order to apply them for AFM1 analysis in naturally contaminated milk samples, and to assess the closeness of agreement between results of three different methods...

We report here a transgenic murine induced pluripotent stem cell (iPSC) line expressing puromycin N-acetyltransferase (PAC) and enhanced green fluorescent protein (EGFP) under the control of α-myosin heavy chain promoter. This transgenic cell line reproducibly differentiates into EGFP-expressing cardiomyocytes (CMs) which can be generated at high purity with puromycin treatment and exhibit molecular and functional properties of immature heart muscle cells. This genetically modified iPSC line can be used for assessment of the utility of CMs for myocardial repair, pharmacological and toxicological applications and development of improved cardiac differentiation protocols...
