After decades of rapid increase, the rate of obesity in adults in the USA is beginning to slow and the rate of childhood obesity is stabilizing. Despite these improvements, the obesity epidemic continues to be a major health and financial burden. Obesity is associated with serious negative health outcomes such as cardiovascular disease, type II diabetes, and, more recently, cognitive decline and various neurodegenerative dementias such as Alzheimer's disease. In the past decade, major advancements have contributed to the understanding of the role of the central nervous system (CNS) in the development of obesity and how peripheral hormonal signals modulate CNS regulation of energy homeostasis...

BACKGROUND AIMS: DUOC-01, a cell product being developed to treat demyelinating conditions, is composed of macrophages that arise from CD14(+) monocytes in the mononuclear cell (MNC) population of banked cord blood (CB). This article demonstrates that expression of multiple gene products that promote remyelination is rapidly up-regulated during manufacturing of DUOC-01 from either MNC or purified CB CD14(+) monocytes. METHODS: Cell cultures were initiated with MNC or with immunoselected CD14(+) monocytes isolated from the same CB unit...

Recent genomic studies of sporadic clear cell renal cell carcinoma (ccRCC) have uncovered novel driver genes and pathways. Given the unequal incidence rates among men and women (male:female incidence ratio approaches 2:1), we compared the genome-wide distribution of the chromosomal abnormalities in both sexes. We observed a higher frequency for the somatic recurrent chromosomal copy number variations (CNVs) of autosomes in male subjects, whereas somatic loss of chromosome X was detected exclusively in female patients (17...

BACKGROUND: Storage of red blood cells (RBCs) under blood bank conditions promotes metabolic modulation within the RBC. This "metabolic storage lesion" may affect the quality and safety of the transfused RBCs. The aim of this study is to determine the metabolic changes in stored RBCs over 42 days of routine storage followed by a US Food and Drug Administration-approved method of rejuvenation, freezing, and preparation for transfusion. STUDY DESIGN AND METHODS: We exploited a mass spectrometry-based metabolomics approach to monitor 42-day-stored citrate phosphate dextrose/AS-1 RBCs (n = 29) that were rejuvenated, glycerolized and frozen, then thawed and deglycerolized, and held for 24 hours at 1 to 6ºC in saline-glucose...

Blood banks use pathogen inactivation (PI) technologies to increase the safety of platelet concentrates (PCs). The characteristics of PI-treated PCs slightly differ from those of untreated PCs, but the underlying reasons are not well understood. One possible cause is the generation of oxidative stress during the PI process. This is of great interest since reactive oxygen species (ROS) act as second messengers in platelet functions. Furthermore, there are links between protein oxidation and phosphorylation, another mechanism that is critical for cell regulation...

P-glycoprotein (P-gp), Breast cancer resistance protein (BCRP) and Multidrug resistance-associated protein 2 (MRP2) residing at the blood-brain barrier (BBB) and the blood-spinal cord barrier (BSCB) are major obstacles for drug delivery to the Central Nervous System (CNS). Disease-induced changes of these xenobiotic transporters at the CNS barriers have been previously documented. Changes in the functional expression of these transporters at the CNS barriers would limit the clinical efficacy of therapeutic agents targeting the CNS...

BACKGROUND AIMS: Thymic-derived regulatory T cells (tTreg) are critical regulators of the immune system. Adoptive tTreg transfer is a curative therapy for murine models of autoimmunity, graft rejection, and graft-versus-host disease (GVHD). We previously completed a "first-in-human" clinical trial using in vitro expanded umbilical cord blood (UCB)-derived tTreg to prevent GVHD in patients undergoing UCB hematopoietic stem cell transplantation (HSCT). tTreg were safe and demonstrated clinical efficacy, but low yield prevented further dose escalation...

BACKGROUND: Red blood cells (RBCs) contain large amounts of iron, and periodic therapeutic phlebotomy is thus the main treatment for hereditary hemochromatosis (HH). However, the donation of therapeutic phlebotomy products from asymptomatic patients for transfusion purposes remains controversial. In this study, we compared the quality of RBCs obtained from HH patients with those of non-HH RBCs, within the allowed 42-day storage period. STUDY DESIGN AND METHODS: RBCs were obtained from HH patient donors and random regular blood donors by whole blood collection...

Microglia and monocytes play important roles in regulating brain remyelination. We developed DUOC-01, a cell therapy product intended for treatment of demyelinating diseases, from banked human umbilical cord blood (CB) mononuclear cells. Immunodepletion and selection studies demonstrated that DUOC-01 cells are derived from CB CD14(+) monocytes. We compared the ability of freshly isolated CB CD14(+) monocytes and DUOC-01 cells to accelerate remyelination of the brains of NOD/SCID/IL2Rγ(null) mice following cuprizone feeding-mediated demyelination...

The Formosa Fun Coast explosion, occurring in a recreational water park located in the Northern Taiwan on 27 June 2015, made 499 people burn-injured. For those who had severe burn trauma, surgical intervention and fluid resuscitation were necessary, and potential blood transfusion therapy could be initiated, especially during and after broad escharotomy. Here, we reviewed the literature regarding transfusion medicine and skin grafting as well as described the practicing experience of combined tissue and blood bank in the burn disaster in Taiwan...

INTRODUCTION: Human lymphotropic virus (HTLV I/II) is a retrovirus that is prevalent across the Colombian Pacific coast, and is potentially transmissible by transfusion. Blood bank screening has been regulated since 2004, in order to reduce transmission of HTLV I/II through donation. Information on the seroprevalence of the virus in southwestern Colombia is limited.  OBJECTIVE: To determine the seroprevalence and the behavior of reactivity to HTLV I/II before and after the introduction of Western blot, and the comorbidity of HTLV and other infectious markers in donors from a blood bank in Cali, Colombia...

BACKGROUND: Hepatitis B and C are silent killers not yet recognized as major public health challenges in many developing countries with huge disease burden. In Ethiopia, Hepatitis B is endemic with an average prevalence of 10.8 %, and the prevalence of Hepatitis C is 2 %. The prevalence of both infections, however, is likely to be underreported due to the lack of diagnostic facilities and appropriate surveillance systems. Ethiopia is also among the many Sub-Sahara African countries lacking a coordinated and systematic national response to chronic viral hepatitis...

Extracellular proteolysis of platelet plasma membrane proteins is an event that ensues platelet activation. Shedding of surface receptors such as glycoprotein (GP) Ibα, GPV and GPVI as well as externalized proteins P-selectin and CD40L releases soluble ectodomain fragments that are subsequently detectable in plasma. This results in the irreversible functional downregulation of platelet receptor-mediated adhesive interactions and the generation of biologically active fragments. In this review, we describe molecular insights into the regulation of platelet receptor and ligand shedding in health and disease...

Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) plays a key regulatory function in glucose oxidation by mediating fluxes through glycolysis or the pentose phosphate pathway (PPP) in an oxidative stress-dependent fashion. Previous studies documented metabolic reprogramming in stored red blood cells (RBCs) and oxidation of GAPDH at functional residues upon exposure to pro-oxidants diamide and H2O2 Here we hypothesize that routine storage of erythrocyte concentrates promotes metabolic modulation of stored RBCs by targeting functional thiol residues of GAPDH...

Becoming parents is one of the greatest wishes of a lot of couples. When their dreams come true, prior to the birth of the child, parents have to face several points: the choice of the name, place of delivery, breast or bottle feeding, etc. Recently, they have to face the issues of cord blood stem cells. Researchers and cord blood banks are also interested in those cells. In many countries a lot of advertising is made around umbilical cord blood stem cells. In France as in England, the use and preservation of cord blood are regulated by the legislators without necessarily having the same approach...

Rural physicians have been practising the technique of emergency bleeding and transfusion called Unbanked Directed (to a specific recipient) Blood Transfusion (UDBT), which has been declared illegal, to meet the need for blood in rural and inaccessible areas. As a result, a crisis has emerged in the availability of blood. Is UDBT a second rate technology for the poor and the disadvantaged? And should we not rather advocate for rapid scaling up of the establishment of blood banks in all areas? We examine the ethical issues related to blood availability in the rural areas...

Marrow donor registration and cord blood banking are essential components of the infrastructure required for unrelated haemopoietic stem cell transplantations. We now have a new law to support and regulate the Marrow Donor Coordination Agency, Cord Blood Banks and the Haematopoietic Stem Cell Provision Support Organization. We also need to have a specific goal for bone marrow and peripheral blood stem cell donor registration, a minimum cord blood bank size, and the demographic data to back the medical needs for unrelated haemopoietic stem cell transplantations...

Historically, study of erythrocyte homeostasis has focussed on the survival of erythrocytes in the blood bank and, especially in pathological circumstances, on the mechanisms leading to accelerated aging and removal from the circulation. Recent proteomic and metabolomic data suggest that erythrocyte metabolism involves more than ATP production and transport of oxygen and carbondioxide; is subject to regulation; and is likely to reflect organismal metabolism. Also, it has become clear that systemic diseases affect erythrocyte homeostasis...
