Umbilical cord blood (CB) banks usually freeze and store CB for clinical transplantation using conventional controlled-rate freezer or the automated BioArchive system. The aim of this study is to compare the quality of CB cryopreserved with conventional and automated methods and to make clear the cause of the quality difference between the two methods. The experiment used 80 CB units: 40 were conventionally cryopreserved and the remainder were cryopreserved with a BioArchive. After thawing, the following measures of CB quality were compared: recovery rates of cell count, cell viability of total nucleated cells (TNCs), mononuclear cells (MNCs), and CD34+ cells, as well as colony-forming unit-granulocyte/macrophage (CFU-GM) content...

INTRODUCTION: Type 1 diabetes is heterogeneous in its presentation and progression. Variations in clinical presentation between children and adults, and with ethnic group warrant further study in the UK to improve understanding of this heterogeneity. Early interventions to limit beta cell damage in type 1 diabetes are undergoing evaluation, but recruitment is challenging. The protocol presented describes recruitment of people with clinician-assigned, new-onset type 1 diabetes to understand the variation in their manner of clinical presentation, to facilitate recruitment into intervention studies and to create an open-access resource of data and biological samples for future type 1 diabetes research...

Vincristine is a widely used chemotherapeutic agent in the treatment of childhood malignancies. Neuropathy is the most common adverse effect. CYP3A4 and CYP3A5 enzymes of cytochrome p450 enzyme system are responsible in vincristine metabolism. Genetic polymorphism may alter the vincristine metabolism and the neurotoxicity rate. In this study, distribution of CYP3A5 alleles among Turkish children with malignancies, relation between CYP3A5 genotype and neurotoxicity rates, as well as severity and duration of neuropathy and total vincristine doses were investigated...

Although patients with "severe" asthma tend to be characterized by ongoing symptoms and airway inflammation despite treatment with high doses of inhaled and systemic corticosteroids, there is increasing recognition of marked phenotypic heterogeneity within affected patients. Although "precision medicine" approaches for patients with severe asthma are needed, there are many hurdles that must be overcome in daily practice. The National Heart, Lung and Blood Institute's Severe Asthma Research Program (SARP) has been at the forefront of phenotype discovery in severe asthma for the past decade...

Extracellular vesicles (EVs) are cell-derived membrane vesicles virtually secreted by all cells, including brain cells. EVs are a major term that includes apoptotic bodies, microvesicles and exosomes. The release of EVs has been recognized as an important modulator in cross-talking between neurons, astrocytes, microglia and oligodendrocytes, not only in central nervous system (CNS) physiology but also in neurodegenerative and neuroinflammatory disease states as well as in brain tumors, such as glioma. EVs are able to cross the blood brain barrier (BBB), spread to body fluids and reach distant tissues...

RATIONALE: In a recent systematic review, aging has been identified as the only factor independently associated with mortality during human acute respiratory distress syndrome (ARDS). We explored this age-dependent severity in a clinically relevant double hit murine ARDS model. METHODS: Young adult (Y, 10-12weeks) and middle-old (O, 12-13months) male C57BL6 mice underwent an aspiration of Escherichia coli lipopolysaccharide (LPS) or control saline vehicle. Twenty hours later, four groups of mice were sacrificed [Y(control), O(control), Y(LPS) and O(LPS)]...

BACKGROUND: We hypothesized that integrating supply chain with clinical communities would allow for clinician-led supply cost reduction and improved value in an academic health system. METHODS: Three clinical communities (spine, joint, blood management) and one clinical community-like physician led team of surgeon stakeholders partnered with the supply chain team on specific supply cost initiatives. The teams reviewed their specific utilization and cost data, and the physicians led consensus-building conversations over a series of team meetings to agree to standard supply utilization...

BACKGROUND: Recent research has shown that women and men respond differently to pain, and that biological mechanisms partially moderate sex-related differences in pain sensitivity. Previous pain studies regarding the relationship between pain and physiological aspects, such as brain function and hormone levels, have demonstrated gender differences. In this study we examined whether male and female autonomic reactivity patterns to pain, defined as increases in heart rate and blood pressure, differ throughout anesthetized abdominal surgical procedures...

The presence of the FORS1 antigen on red blood cells was discovered relatively recently, and in 2012, the International Society of Blood Transfusion (ISBT) acknowledged FORS as blood group system number 031. This rare antigen is carried by a glycosphingolipid and formed by elongation of the P antigen. Most people have naturally occurring anti-FORS1 in their plasma. The clinical significance of these antibodies is unknown in the transfusion setting, but they can hemolyze FORS1+ erythrocytes in the presence of complement in vitro...

The blood group antigen Vel has been one of immunohematology's greatest enigmas: the variation in antigen strength from one individual to another, the property of anti-Vel to readily hemolyze Vel+ red blood cells (RBCs), and the difficulty to screen for sufficient numbers of Vel- blood donors had made Vel a tough nut to crack. In 2013, a small, previously unknown protein called small integral membrane protein 1 (SMIM1) was identified on the RBC by three independent research groups using different approaches, and all three groups demonstrated that Vel- RBCs lacked SMIM1...

The inherited marrow failure syndromes (IBMFS) are a heterogeneous group of diseases characterized by failure in the production of one or more blood lineage. The clinical manifestations of the IBMFS vary according to the type and number of blood cell lines involved, including different combinations of anemia, leukopenia, and thrombocytopenia. In some IBMFS, systemic non-hematologic manifestations, including congenital malformations, mucocutaneous abnormalities, developmental delay, and other medical complications, may be present...
