Iron Bioavailability Of Hemoglobin From Soy Root Nodules Using A Caco-2 Cell Culture Model, Amy K. Proulx, Manju B. Reddy

Manju B. Reddy

Heme iron has been identified in many plant sourcesmost commonly in the root nodules of leguminous plants, such as soy. Our objective was to test the effectiveness of soy root nodule (SRN) and purified soy hemoglobin (LHb) in improving iron bioavailability using an in vitro Caco-2 cell model, with ferritin response as the bioavailability index. We assessed bioavailability of iron from LHb (either partially purified (LHbA) or purified (LHbD)) with and without food matrix and compared it with that from bovine hemoglobin (BHb), ferrous sulfate (FeSO4), or SRN. Bioavailability of each treatment was normalized to 100% of the FeSO4 treatment ...

Splenic Infarction: An Uncommon Presentation Of Acute Infectious Mononucleosis, Madhulika Urella, Roma Srivastava, Waseem Ahmed, Yehuda Lebowicz

Marshall Journal of Medicine

Splenic infarction is a relatively uncommon diagnosis. It occurs when the splenic artery or one of its sub-branches is occluded with an infected or bland embolus or clot. Splenic infarction may be caused by atrial fibrillation, bacterial endocarditis, sickle cell disease, antiphospholipid syndrome, and trauma whereas an infectious etiology is uncommon. It is considered a rare presentation of acute infectious mononucleosis. Currently, its pathogenesis is still unclear. We describe a 24-year-old African American female who was admitted for evaluation of left-sided chest pain. Chest imaging, abdominal ultrasound, and initial laboratory data were normal, followed by a negative hypercoagulability panel. Signs ...

To investigate the potential functional cooperation between p27Kip1 and p130 in vivo, we generated mice deficient for both p27Kip1 and p130. In p27Kip1−/−;p130−/− mice, the cellularity of the spleens but not the thymi is significantly increased compared with that of their p27Kip1−/− counterparts, affecting the lymphoid, erythroid, and myeloid compartments. In vivo cell proliferation is significantly augmented in the B and T cells, monocytes, macrophages, and erythroid progenitors in the spleens of p27Kip1−/−; p130−/− animals. Immunoprecipitation and immunodepletion studies indicate that p130 can compensate for the absence of p27Kip1 in binding to and ...

UMass Center for Clinical and Translational Science Research Retreat

Exposure of an Rh negative mother to red blood cells (RBCs) of an Rh positive fetus results in alloimmunization and development of anti-RhD antibodies. The anti-RhD antibodies cause hemolytic disease of the new born babies during subsequent pregnancies. Current prophylactic treatment involves polyclonal anti-RhD IgG purified from plasma of humans and is administered in approximately 20% of pregnancies. While the current prophylaxis is effective, it involves the use of human plasma and non-RhD specific antibodies, thus posing a risk of transmitting infections and undesired antibody reactions. Moreover, there is a serious scarcity of plasma donors to meet the requirement of ...

Cardeza Foundation for Hematologic Research

Sickle cell disease (SCD) is a group of inherited blood disorders that have in common a mutation in the sixth codon of the β-globin (HBB) gene on chromosome 11. However, people with the same genetic mutation display a wide range of clinical phenotypes. Fetal hemoglobin (HbF) expression is an important genetic modifier of SCD complications leading to milder symptoms and improved long-term survival. Therefore, we performed a genome-wide association study (GWAS) using a case-control experimental design in 244 African Americans with SCD to discover genetic factors associated with HbF expression. The case group consisted of subjects with HbF≥8.6 ...

Novel Oral Transforming Growth Factor-Beta Signaling Inhibitor Ew-7197 Eradicates Cml-Initiating Cells, Kazuhito Naka, Shaoguang Li, Dae-Kee Kim

Open Access Articles

Recent strategies for treating CML patients have focused on investigating new combinations of tyrosine kinase inhibitors (TKIs) as well as identifying novel translational research agents that can eradicate CML leukemia-initiating cells (CML-LICs). However, little is known about the therapeutic benefits such CML-LIC targeting therapies might bring to CML patients. In this study, we investigated the therapeutic potential of EW-7197, an orally bioavailable transforming growth factor-beta signaling inhibitor which has recently been approved as an Investigational New Drug (NIH, USA), to suppress CML-LICs in vivo. Compared to TKI treatment alone, administration of TKI plus EW-7197 to CML-affected mice significantly delayed disease ...

Reduction Of Oxidative Stress And Storage Lesions (Rcsl) In Red Blood Cells - Analysis Of Ascorbic Acid (Aa), N-Acetylcysteine Amide (Ad4), And Serotonin (5-Ht), Shanmuka Gadiraju

Undergraduate Research Posters

Oxidative stress is a common occurrence in red blood cell (RBC) storage in blood banks throughout the world. Typically RBC units stored under routine standard protocol (stored in SAGM-CPD additive solution) can only be kept up to 42 days for transfusion usage before being discarded. I am studying the effects of Ascorbic Acid (AA), N-acetylcysteine amide (AD4), and Serotonin (5-HT) as additives in blood bank storage because I want to find out if these additives can reduce storage-induced oxidative stress on red blood cells (RBCs), in order to help my reader understand how potential blood storage additives can affect the ...

Sickle cell anemia (SCA) is an inherited hemolytic anemia with compensatory reticulocytosis. Recent studies have shown that increased levels of reticulocytosis during infancy are associated with increased hospitalizations for SCA sequelae as well as cerebrovascular pathologies. In this study, absolute reticulocyte counts (ARC) measured prior to transfusion were analysed among a cohort of 29 pediatric SCA patients receiving chronic transfusion therapy (CTT) for primary and secondary stroke prevention. A cross-sectional flow cytometric analysis of the reticulocyte phenotype was also performed. Mean duration of CTT was 3.1 ± 2.6 years. Fifteen subjects with magnetic resonance angiography (MRA) -vasculopathy had significantly ...

Kras Codon 12 And 13 Mutations In Relation To Disease-Freesurvival In Braf-Wild-Type Stage Iii Colon Cancers From An Adjuvant Chemotherapytrial (N0147 Alliance)., Harry H Yoon, David Tougeron, Qian Shi, Steven R Alberts, Michelle R Mahoney, Garth D Nelson, Suresh Nair, Stephen N Thibodeau, Richard M Goldberg, Daniel J Sargent, Frank A Sinicrope

Suresh G. Nair MD

PURPOSE: We examined the prognostic impact of specific KRAS mutations in patients with stage III colon adenocarcinoma receiving adjuvant FOLFOX alone or combined with cetuximab in a phase III trial (N0147). Analysis was restricted to BRAF-wild-type tumors, because BRAF mutation was associated with poor prognosis, and BRAF and KRAS mutations are mutually exclusive.

EXPERIMENTAL DESIGN: The seven most common KRAS mutations in codon 12 and codon 13 were examined in 2,478 BRAF-wild-type tumors. Because KRAS mutations in codon 12 (n = 779) or 13 (n = 220) were not predictive of adjuvant cetuximab benefit, study arms were pooled for analysis. Disease-free ...
