A healthy lifestyle is important in CVD prevention and treatment through effects on modifiable CVD risk factors, particularly blood pressure. Although the major drawback is the low level of adherence over time, appropriate lifestyle changes may safely and effectively prevent and treat hypertension. The recommended dietary approaches that have been shown to be capable of reducing blood pressure are: salt restriction, moderation of alcohol consumption, high consumption of vegetables and fruits and low-fat and other types of diet, and weight reduction...

Identifying circulating tumour DNA (ctDNA) for monitoring of cancer therapy is dependent on the development of readily designed, sensitive cancer-specific DNA markers. Genomic rearrangements that are present in the vast majority of cancers provide such markers.Tumour DNA isolated from two fresh-frozen lung tumours underwent whole genome sequencing. Genomic rearrangements were detected using a new computational algorithm, GRIDSS. Four genomic rearrangements from each tumour were chosen for further study using rearrangement-specific primers...

BACKGROUND: Transfusion of red blood cells (RBCs) is associated with adverse outcome, but the causative factor is unknown. Extracellular vesicles (EVs) have pro-inflammatory properties. We hypothesized that EVs released from both fresh and stored RBC products can induce a host inflammatory response in a dose-dependent manner. METHODS: Whole blood was incubated with supernatant from RBC units stored for different time periods, either containing (different numbers of) EVs or depleted from EVs...

Monitoring the immunological functionality of vaccine formulations is critical for vaccine development. While the traditional approach using established animal models has been relatively effective, the use of animals is costly and cumbersome, and animal models are not always reflective of a human response. The development of a human-based approach would be a major step forward in understanding how vaccine formulations might behave in humans. Here, we describe a platform methodology using fresh human whole blood (hWB) to monitor adjuvant-modulated, antigen-specific responses to vaccine formulations, which is amenable to analysis by standard immunoassays as well as a variety of other analytical techniques...

INTRODUCTION: We have recently shown that human whole blood stored at 4°C maintains hemostatic and platelet function. In this study, we compared restoration of hemodynamic, metabolic and hemostatic function after limited resuscitation with rat fresh whole blood, rat stored whole blood, or Lactated Ringers in traumatized rats. METHODS: Rat whole blood was stored for 10 days at 4°C for evaluation of hemostatic function. Polytrauma was performed on isoflurane-anesthetized Sprague-Dawley rats (350-450 g) by damage to the intestines, liver, right leg skeletal muscle and right femur fracture, followed by 40% hemorrhage...

INTRODUCTION: Severe trauma, hemorrhage and resuscitation can lead to a trauma related acute lung injury that involves rapid infiltration of immune cells and platelets. This infiltration involves exymatic degradation of matrix proteins, including plasmin, and causes loss of barrier function. Since tranexamic acid (TXA) inhibits plasminogen/ plasmin binding to target substrates, it may attenuate loss of barrier function after severe trauma, hemorrhage and resuscitation. METHODS: Sprague-Dawley rats were subjected to polytrauma (laparotomy, and trauma to intestines, liver, right leg skeletal muscle and right femur fracture), then bled 40% of their blood volume...

Glioblastoma multiforme (GBM-WHO grade IV) is the most common and the most aggressive form of brain tumors in adults with the median survival of 10-12 months. The diagnostic detection of extracellular matrix (ECM) component in the tumour microenvironment is of prognostic value. In this paper, the fibrillar collagen deposition associated with vascular elements in GBM were investigated in the fresh specimens and unstained histological slices by using multiphoton microscopy (MPM) based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG)...

BACKGROUND: To demonstrate the analytical validity of an RNA classifier for medullary thyroid carcinoma (MTC). METHODS: Fresh-frozen tissue specimens were obtained from commercial sources, and MTC diagnoses were confirmed by histopathology review. De-identified patient fine-needle aspiration biopsies (FNABs) and whole blood from normal donors were obtained. Total RNA was extracted, amplified, and hybridized to custom microarrays for gene expression analysis. Gene expression data was normalized and classified via a machine learning algorithm...

Historically, the bleeding episodes in subjects with coagulation disorders were treated by substitution therapy, initially using whole blood and fresh frozen plasma and more recently with specific factor concentrate. Nowadays, patients with hemophilia have the possibility to choose different effective and safe treatments including novel extended half-life and alternative hemostatic drugs. The availability of novel extended half-life products could probably overcome current prophylaxis limitations particularly in hemophilia B by reducing frequency of injections, achieving a higher trough level and improving the quality of life of the patients...

BACKGROUND: Various versions of the monocyte monolayer assay (MMA) have been used to assess clinical significance of red blood cell (RBC) alloantibodies in transfusion for more than 35 years. However, the optimal conditions, including anticoagulant used for whole blood samples, temperature and duration of storage, and optimal pH for assessing the response of monocytes to antibody-bound RBCs, have never been clearly delineated. STUDY DESIGN AND METHODS: Whole blood from healthy donors was collected in ACD, EDTA, or heparin and stored at room temperature (RT) versus 4°C for up to 2 days...

CONTEXT: Waterpipe smoking (WPS) has been known for over 400 years. It has been spread widely especially between youth because of the addition of pleasant flavor and because it was misconsidered to be less harmful than cigarette. OBJECTIVE: In this study, we investigated the effect of waterpipe smoking on renal oxidative and functional parameters and compared that at acute and chronic exposure time in mice. MATERIALS AND METHODS: Mice were divided into three groups, namely acute, chronic and fresh air control...

Rapid destruction of hepatocytes after hepatocyte transplantation has hampered the application of this procedure clinically. The instant blood mediated inflammatory reaction (IBMIR) is a plausible underlying cause for this cell loss. The present study was designed to evaluate the capacity of low molecular weight dextran sulfate (LMWDS) to control these initial reactions from the innate immune system. Fresh and cryopreserved hepatocytes were tested in an in vitro whole blood model using ABOcompatible blood. The ability to elicit IBMIR and the capacity of LMW-DS (100 µg/mL) to attenuate the degree of activation of the cascade systems was monitored...

Balanced component therapy (BCT) remains the mainstay in trauma resuscitation of the critically battle injured. In austere medical environments, access to packed red blood cells, apheresis platelets, and fresh frozen plasma is often limited. Transfusion of warm, fresh whole blood (FWB) has been used to augment limited access to full BCT in these settings. The main limitation of FWB is that it is not readily available for transfusion on casualty arrival. This small case series evaluates the impact early, mechanism-of-injury (MOI)-based, preactivation of the walking blood bank has on time to transfusion...

Transfusion related acute Lung injury (TRALI) though a serious blood transfusion reaction with a fatality rate of 5-25 % presents with acute respiratory distress with hypoxaemia and noncardiac pulmonary oedema within 6 h of transfusion. In non fatal cases, it may resolve within 72 h or earlier. Although reported with an incidence of 1:5000, its true occurrence is rather unknown. Pathogenesis is believed to be related to sequestration and adhesion of neutrophils to the pulmonary capillary endothelium and its activation leading to its destruction and leaks...

Plasmodium falciparum parasitisation can result in a systemic inflammatory response characterised by profound neurologic complications, renal failure, adult respiratory distress syndrome and disseminated intravascular coagulation with high morbidity and mortality. Complete obstruction to medium sized arteries seems not to have been reported before while the role of sequential whole blood and plasma exchange may be an under-utilised intervention that is life-saving in selected cases. A 25 year old patient was referred with mental confusion, rapidly deteriorating vision, hypotensive and oliguric, massive generalised oedema compressing muscles leading to rhabdomyolysis and impending gangrene of both lower limbs...

BACKGROUND: Uncontrolled major hemorrhage and delayed evacuation remain substantial contributors to potentially survivable combat death, along with mission, environment, terrain, logistics, and hostile action. Life-saving interventions and the onset of acute traumatic coagulopathy (ATC) may also contribute. OBJECTIVE: Analyze US casualty records from the DoD Trauma Registry, using International Normalized Ratio (INR) of 1.5 for onset of ATC. METHODS: Retrospective cohort study from September 2007 to June 2011, inclusive...

Cytosolic nucleotide oligomerisation domain (NOD)-like receptors play an important role in host defence against infection. Reduced NOD1 expression has been observed in dysfunctional neutrophils derived from periparturient cattle known to be most susceptible to coliform mastitis. However, whether impairment of NOD1 suppresses the immune responses of bovine neutrophils during bacterial infections remains unknown. Crude (phenol extracted) lipopolysaccharide (cLPS), which often contains other immunostimulatory molecules, including NOD1 agonist, is known to induce almost the whole bacterial response...
