BACKGROUND: Red blood cell (RBC) transfusion is associated with organ failure. The mechanism remains unknown, but may include adherence of blood cells to the microvasculature. We hypothesized that RBC-derived extracellular vesicles (EVs) interact with monocytes to activate endothelial cells. STUDY DESIGN AND METHODS: Human umbilical vein endothelial cells were incubated with supernatant from fresh and stored RBC units either containing EVs or depleted from EVs, with or without the addition of immune cells...

: This study describes childhood fracture rates in Norway, a country known for high fracture rates in the adult population. Fracture rates correspond with other reports from Scandinavia, although with a slightly higher proportion in girls. Indications of increased vulnerability during stages of puberty require further exploration. INTRODUCTION: Fractures are common injuries during childhood. Incidence rates and patterns vary, but population-based data are scarce...

BACKGROUND: Coastal lagoons are ecosystems of major importance as they host a number of species tolerant to disturbances and they are highly productive. Therefore, these ecosystems should be protected to ensure stability and resilience. The lagoons of Amvrakikos Gulf form one of the most important lagoonal complexes in Greece. The optimal ecological status of these lagoons is crucial for the well-being of the biodiversity and the economic prosperity of the local communities. Thus, monitoring of the area is necessary to detect possible sources of disturbance and restore stability...

Increased liver fat may be caused by insulin resistance and adipose tissue inflammation or by the common I148M variant in PNPLA3 at rs738409, which lacks both of these features. We hypothesised that obesity/insulin resistance rather than liver fat increases circulating coagulation factor activities. We measured plasma prothrombin time (PT, Owren method), activated partial thromboplastin time (APTT), activities of several coagulation factors, VWF:RCo and fibrinogen, and D-dimer concentration in 92 subjects divided into groups based on insulin sensitivity [insulin-resistant ('IR') versus insulin-sensitive ('IS')] and PNPLA3 genotype (PNPLA3(148MM/MI) vs PNPLA3(148II))...

Leiomyosarcoma is one of the soft tissue sarcomas that could originate from different parts of body and are mostly presented as retropritoneal mass. Leiomyosarcomas of vascular origin are particularly rare tumors occurring mainly in inferior vena cava (IVC). Here, we report the case of a 35-year-old male patient who presented with ascites and jaundice. Further evaluation revealed large hepatic and cardiac masses with extension to IVC. Since it was not possible to determine the point of origin of leiomyosarcoma, the patient received chemotherapy under diagnosis of metastatic leiomyosarcoma but unfortunately passed away...

OBJECTIVE: To investigate the association between blood pressure (BP) levels and risk of intracerebral hemorrhage (ICH) after ischemic stroke. METHODS: We performed a post hoc analysis of data from the Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) trial, a randomized clinical trial including 20,332 patients with recent noncardioembolic ischemic stroke. BP measurements were divided into predefined categories. We calculated incidence rates per BP category and performed multivariable Cox regression analysis with systolic blood pressure (SBP) and diastolic blood pressure (DBP) categories as time-dependent covariables...

While the Mediterranean Sea has been designated as a Global Biodiversity Hotspot, assessments of cetacean population abundance are lacking for large portions of the region, particularly in the southern and eastern basins. The challenges and costs of obtaining the necessary data often result in absent or poor abundance information. We applied capture-recapture models to estimate abundance, survival and temporary emigration of odontocete populations within a 2,400 km2 semi-enclosed Mediterranean bay, the Gulf of Corinth...

Microparticles released by activated/apoptotic cells exhibit coagulation activity as they express phosphatidylserine and some of them - tissue factor. We compared procoagulant properties of microparticles from monocytes, granulocytes, platelets and endothelial cells and assessed the impact of tissue factor in observed differences. Microparticles were sedimented (20 000g, 30 min) from the supernatants of activated monocytes, monocytic THP-1 cells, granulocytes, platelets and endothelial cells. Coagulation activity of microparticles was examined using plasma recalcification assay...

BACKGROUND: Opioid overdose is a growing concern in the United States and internationally. Prehospital or pre-medical-personnel (lay person) administration of naloxone, an opioid antagonist, to reverse overdose, is an expanding mode of harm reduction. Recently, community clinics, methadone clinics, needle exchanges, some pharmacies and other health care facilities have made naloxone available to the community. CASE: This case describes heroin overdose reversal of a 28-year-old male who had been using about a gram of heroin intravenously for 3 years, but recently reduced frequency of use in an attempt to stop...

Canonical signal transduction via heterotrimeric G proteins is spatiotemporally restricted, i.e., triggered exclusively at the plasma membrane, only by agonist activation of G protein-coupled receptors via a finite process that is terminated within a few hundred milliseconds. Recently, a rapidly emerging paradigm has revealed a noncanonical pathway for activation of heterotrimeric G proteins via the nonreceptor guanidine-nucleotide exchange factor, GIV/Girdin. Biochemical, biophysical, and functional studies evaluating this pathway have unraveled its unique properties and distinctive spatiotemporal features...

The medullary thick ascending limb of Henle's loop (mTAL) is crucial for urine-concentrating ability of the kidney. It is water tight and able to dilute the luminal fluid by active transcellular NaCl transport, fueling the counter current mechanism by increasing interstitial osmolality. While chloride is exclusively transported transcellularly, approx. 50% of sodium transport occurs via the paracellular route, driven by the lumen-positive transepithelial potential. Antidiuretic hormone (AVP) is known to increase active NaCl transport to support collecting duct water reabsorption...

Brown adipose tissue (BAT) is key to energy homeostasis. By virtue of its thermogenic potential it may dissipate excessive energy, regulate body weight, and increase insulin sensitivity. Catecholamines are critically involved in the regulation of BAT-thermogenesis, yet research has focussed on the effects of noradrenaline and adrenaline. Some evidence suggests a role of dopamine (DA) in BAT-thermogenesis but the cellular mechanisms involved have not been addressed. We employed our extensively characterised murine brown adipocyte cells...

Processing the motivational relevance of a visual scene and reacting accordingly is crucial for survival. Previous work suggests the emotional content of naturalistic scenes affects response speed, such that unpleasant content slows responses whereas pleasant content accelerates responses. It is unclear whether these effects reflect motor-cognitive processes, such as attentional orienting, or vary with the function/outcome of the motor response itself. Four experiments manipulated participants' ability to terminate the picture (offset control) and, thereby, the response's function and motivational value...
