AF4 and AF4N protein complexes: recruitment of P-TEFb kinase, their interactome and potential functions.

AF4/AFF1 and AF5/AFF4 are the molecular backbone to assemble “super-elongation complexes” (SECs) that have two main functions: (1) control of transcriptional elongation by recruiting the positive transcription elongation factor b (P-TEFb ...

Type B lactic acidosis: a rare but life threatening hematologic emergency. A case illustration and brief review.

Major strides have been made in improving the treatment of medical emergencies associated with malignancies. Nonetheless, metabolic emergencies in cancer patients can often times be life-threatening. Type B lactic acidosis is a rare but potentially fatal ...

PNH is a debilitating, fatal but treatable disease: same disease, different clinical presentations.

Paroxysmal nocturnal hemoglobinuria (PNH) is a disease characterized by chronic persistent hemolysis, multi-organ damage and eventually multiple organ failure. PNH develops as a result of increased sensitivity to complement due to an acquired deficiency ...

Methotrexate-associated primary cutaneous CD30-positive cutaneous T-cell lymphoproliferative disorder: a case illustration and a brief review.

Methotrexate (MTX) is a commonly used anti-metabolite agent. Increased risk of lymphoproliferative disorders (LPD) in patients with rheumatoid arthritis (RA) has been documented with the prolonged use of immunosuppressive medications such as MTX. This ...

Maytansinoid immunoconjugate IMGN901 is cytotoxic in a three-dimensional culture model of multiple myeloma.

Environmental-mediated drug-resistance (EM-DR) presents a major challenge for therapeutic development. Tissue microenvironment in the form of extracellular matrix, soluble factors, and stroma contribute to EM-DR. In multiple myeloma (MM), drug-resistance ...

Pesg PNH diagnosis, follow-up and treatment guidelines.

PNH Education and Study Group (PESG) have been established in December 2013 as a non-profit, independent, medical organization www.pesg.org. Paroxysmal Nocturnal Hemoglobinuria (PNH) is a multi-systemic disease that should be treated with a multidisciplinary ...

DDX6 transfers P-TEFb kinase to the AF4/AF4N (AFF1) super elongation complex.

AF4/AFF1 and AF5/AFF4 are both backbones for the assembly of “super elongation complexes” (SECs) that exert 2 distinct functions after the recruitment of P-TEFb from the 7SK snRNP: (1) initiation and elongation of RNA polymerase II gene ...

Efficacy and safety of ClairYg®, a ready-to-use intravenous immunoglobulin, in adult patients with primary immune thrombocytopenia.

Purpose: The present study was designed to assess the efficacy and safety of IGNG that is a new liquid, saccharose and maltose-free highly purified ready-to-use 5% intravenous immunoglobulin (IVIg), in primary immune thrombocytopenic patients with severe ...

Concomitant lymphoplasmacytic lymphoma and plasma cell myeloma, a diagnostic challenge.

Background: Lymphoplasmacytic lymphoma and plasma cell myeloma are two B cell lymphoproliferative neoplasms derived from mature B-lymphocytes in different differentiation stages. The coexistence of these two tumors in the same patient is exceedingly rare ...

Factors affecting the body mass index, haemoglobin and serum ferritin level in students.

Ferritin is a protein found in reticuloendothelial system and does not work only as a mid-size protein during Hemoglobin synthesis but also as storage protein for iron delivery. This cross sectional study was conducted in District Shaheed Benazirabad ...

Treatment of older patients with acute myeloid leukemia (AML): revised Canadian consensus guidelines.

The treatment of acute myeloid leukemia (AML) in older patients is undergoing rapid changes, with a number of important publications in the past five years. Because of this, a group of Canadian leukemia experts has produced an update to the Canadian Consensus ...

Luminol-amplified chemiluminescence detects mainly superoxide anion produced by human neutrophils.

Reactive oxygen species (ROS) are produced by numerous biological systems and by several phagocytes such as neutrophils and macrophages. ROS include mostly superoxide anion, hydrogen peroxide, singlet oxygen and hydroxyl radical, which are involved in ...

Cytogenetic study is not essential in patients with aplastic anemia.

Depending on contemporary treatment approach of aggressive immunosuppression, Aplastic Anemia (AA) is caused by immunological destruction of otherwise normal hematopoietic stem cells. The aim was to summarize the cytogenetic abnormalities in AA patients ...

Evaluation of bone mineral density and related parameters in patients with haemophilia: a single center cross-sectional study.

Haemophilia has been associated with low bone mineral density (BMD) probably due to some predisposing factors. The aim of this study was to evaluate the relationship between BMD and potential clinical predictors in adult haemophilic patients. Fortynine ...

Trisomy 6 as the sole stemline abnormality in a patient with acute monocytic leukemia: a case report.

It is rare for trisomy 6 to occur as the sole autosomal anomaly in hematological malignancies, but this finding has been reported to be associated with a hypoplastic bone marrow. We report the case of a 75-year-old male with acute monocytic leukemia, ...

An isolated der(1;21)(q10;q10) translocation in a patient with myelodysplastic syndrome: a case report.

Whole-arm translocations are relatively rare among hematological malignancies. There are a few reports on myeloid malignancies harboring der(1;21)(q10;q10). A 65-year-old male was referred to our hospital due to squamous cell carcinoma of the lung. Pembrolizumab ...

Comparing serum levels of zinc, copper, certain antioxidant vitamins and dietary intakes in acute lymphoblastic leukemia (ALL) patients before and after chemotherapy.

Acute lymphoblastic leukemia (ALL) is a malignant hematologic disease. Cancer and its treatments can affect biological functions and change the nutritional status of patients. Zinc and copper are important cofactors for several enzymes and play an important ...

Advances in biology of acute lymphoblastic leukemia (ALL) and therapeutic implications.

Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer and also occurs in adults. Although the outcomes of multi-agent chemotherapy regimens have greatly improved, high toxicity and relapses in many patients necessitate the development ...

Use of direct oral anticoagulants in daily practice.

In recent years, the options for anticoagulant therapy have examined new direct oral anticoagulants (DOACs) comprising direct thrombin inhibitors (dabigatran) and direct factor Xa inhibitors (rivaroxaban, apixaban, and edoxaban). These agents represent ...

Partial pressure of oxygen in the human body: a general review.

The human body is a highly aerobic organism, in which it is necessary to match oxygen supply at tissue levels to the metabolic demands. Along metazoan evolution, an exquisite control developed because although oxygen is required as the final acceptor ...

Patched homolog 1 (PTCHI) gene mutations can predict the outcome of chronic myeloid leukemia patients?

Background: The Hedgehog (Hh) pathway is stimulated by inactivating mutations of Patched Homolog 1 (PTCH1) gene. There is accumulating evidence that Hh signaling plays a critical role in the pathogenesis of various haemopoietic malignancies. Particular ...
