Sirtuins (SIRT), first described as nicotinamide adenine dinucleotide (NAD(+))-dependent type III histone deacetylases, are produced by cells to support in the defense against chronic stress conditions such as metabolic syndromes, neurodegeneration, and cancer. SIRT-3 is one of the most studied members of the mitochondrial sirtuins family. In particular, its involvement in metabolic diseases and its dual role in cancer have been described. In the present review, based on the evidence of SIRT-3 involvement in metabolic dysfunctions, we aimed to provide an insight into the multifaceted role of SIRT-3 in many solid and hematological tumors with a particular focus on hepatocellular carcinoma (HCC)...

Drinking water arsenic (WAs) exposure has been linked to a number of detrimental health outcomes including anemia, primarily among pregnant women. Little is known about the effects of arsenic (As) on hematological disorders among men. We have examined the role of As exposure on hematological indicators of anemia in a group of men exposed to a wide range of As in their drinking water. We conducted a cross-sectional investigation among 119 healthy men in the Health Effects of As Longitudinal Study (HEALS) cohort, in rural Bangladesh...

INTRODUCTION: For patients receiving intravenous immunoglobulin (IVIG), renal and hemolytic side effects are well recognized. However, there is very little data on the effects of chronic IVIG therapy. METHODS: We retrospectively analyzed laboratory data on 166 patients who received IVIG for 12 months with dosing from 0.441 gm/kg/month to 2.58 gm/kg/month, measuring changes in hematocrit and glomerular filtration rates (GFR) at 6 and 12 months. RESULTS: Of the 2,232 infusions, there were no incidents of clinical hemolysis...

Homing of hematopoietic stem cells (HSC) to their microenvironment niches in the bone marrow is a complex process with a critical role in repopulation of the bone marrow after transplantation. This active process allows for migration of HSC from peripheral blood and their successful anchoring in bone marrow before proliferation. The process of engraftment starts with the onset of proliferation and must, therefore, be functionally dissociated from the former process. In this overview, we analyze the characteristics of stem cells (SCs) with particular emphasis on their plasticity and ability to find their way home to the bone marrow...

RAD51 is an indispensable homologous recombination protein, necessary for strand invasion and crossing over. It has recently been designated as a Fanconi anemia (FA) gene, following the discovery of two patients carrying dominant-negative mutations. FA is a hereditary DNA-repair disorder characterized by various congenital abnormalities, progressive bone marrow failure, and cancer predisposition. In this report, we describe a viable vertebrate model of RAD51 loss. Zebrafish rad51 loss-of-function mutants developed key features of FA, including hypocellular kidney marrow, sensitivity to cross-linking agents, and decreased size...

Monoclonal gammopathy of undetermined significance (MGUS) is the common pre-malignant B cell disorders with a general prevalence of 3-5 % at age over 50. Because of the potential malignant transformation and immune insufficiency, pre-transplant MGUS recipient should be carefully followed after allograft transplantation. The post-transplant prognosis and quality of life (QOL) in patient with MGUS have not yet been fully determined. The aim of this study is to evaluate function and pathology of the renal allograft and self-assessment QOL changes during 2 years after transplantation in our case of MGUS-bearing recipient...

Cyclophosphamide (CTX) is a chemotherapeutic agent widely used to treat ovarian, breast, and hematological cancers as well as autoimmune disorders. Such chemotherapy is associated with reproductive failure and premature ovarian insufficiency. The mechanism by which CTX and or its main metabolite, acrolein, affect female fertility remains unclear, but it is thought to be caused by an overproduction of reactive oxygen species (ROS). Here, we investigated the effect of CTX on metaphase II mouse oocytes obtained from treated animal (120mg/kg, 24 h of single treatment), and oocytes directly exposed to increasing concentrations of CTX and acrolein (n=480; 0, 5, 10, 25, 50, and 100μM) with and without cumulus cells (CCs) for 45min which correlates to the time of maximum peak plasma concentrations after administration...

Bornaviruses are considered to be the causative agent of proventricular dilatation disease (PDD) in psittacine birds. In order to detect hematological and blood chemistry changes during the development of PDD and a possible correlation with clinical symptoms and the virological status, six African grey parrots (Psittacus erithacus) were experimentally infected with parrot bornavirus genotype 4 (PaBV-4) by subcutaneous route. All six parrots developed clinical signs of varying extent and successful infection was confirmed in all the birds by seroconversion or detection of RNA of the PaBV-4 infection strain...

Malignant hematological diseases are mainly due to the occurrence of molecular abnormalities leading to the deregulation of signaling pathways essential for precise cell behavior. High resolution genome analysis using microarray and large-scale sequencing have helped identify several important acquired gene mutations that are responsible for such signaling deregulations across different hematological malignancies. In particular, the genetic landscape of classical myeloproliferative neoplasms (MPNs) has been in large part completed with the identification of driver mutations (targeting the cytokine receptor/JAK2 pathway) that determine MPN phenotype, as well as additional mutations mainly affecting the regulation of gene expression (epigenetics or splicing regulators) and signaling...

Interleukin-1α (IL-1α) and IL-1β are potent inflammatory cytokines that activate local and systemic inflammatory processes and are involved in protective immune responses against infections. However, their dysregulated production and signaling can aggravate tissue damage during infection, inflammatory diseases and chemotherapy-induced intestinal mucositis. Additionally, cytokines of the IL-1 family play an important role in homeostatic as well as 'emergency' hematopoiesis and are involved in the pathogenesis of several myeloid and lymphoid hematological malignancies...

Langerhans cell histiocytosis (LCH), previously known as histiocytosis X, is an uncommon hematological disorder affecting infants and young children. It is the condition characterized by uncontrolled stimulation and proliferation of normal antigen presenting cells, Langerhans cells. Because of its relatively low incidence, limited data are available regarding the epidemiology of LCH, with estimation of 2-5 cases per million inhabitants per year. The purpose of this report is to describe the case of LCH in the 3-year-old male child with multiple focal involvements of bones and to discuss clinical, radiological and histopathological features of LCH and role of the dental surgeon in diagnosing and managing such lesions...

Tumor lysis syndrome (TLS) is a life-threatening disorder that is an oncologic emergency. Risk factors for TLS are well-known, but the current literature shows case descriptions of unexpected acute TLS. Solid tumors and untreated hematologic tumors can lyse under various circumstances in children and adults. International guidelines and recommendations, including the early involvement of the critical care team, have been put forward to help clinicians properly manage the syndrome. Advanced practice nurses may be in the position of triaging and initiating treatment of patients with TLS, and need a thorough understanding of the syndrome and its treatment...
