Self-diffusion of water-soluble fullerene derivative (WSFD) C60 [S(CH2 )3 SO3 Na]5 H in mouse red blood cells (RBC) was characterized by 1 H pulsed field gradient NMR technique. It was found that a fraction of fullerene molecules (~13% of the fullerene derivative added in aqueous RBC suspension) shows a self-diffusion coefficient of (5.5 ± 0.8)·10-12  m2 /s, which is matching the coefficient of the lateral diffusion of lipids in the erythrocyte membrane (DL  = (5.4 ± 0.8)·10-12  m2 /s). This experimental finding evidences the absorption of the fullerene derivative by RBC...

BACKGROUND: Perioperative goal-directed hemodynamic therapy (GDHT) has been advocated in high-risk patients undergoing noncardiac surgery to reduce postoperative morbidity and mortality. We hypothesized that using cardiac index (CI)-guided GDHT in the postoperative period for patients undergoing high-risk surgery for cancer treatment would reduce 30-day mortality and postoperative complications. METHODS: A randomized, parallel-group, superiority trial was performed in a tertiary oncology hospital...

Patient-specific instrumentation (PSI) may contribute to reduced blood loss related to total knee arthroplasty (TKA). The purpose of this study was to compare the estimated hemoglobin (Hb) and red blood cell volume (RBC) losses in two groups of patients undergoing TKA with PSI and conventional instrumentation. Pre- and postoperative blood samples were collected from 22 patients randomly assigned to receive a PSI-assisted or conventional TKA. Post- to preoperative Hb difference was calculated and RBC loss was estimated according to Sehat et al...

Understanding the pathways guiding the development of definitive hematopoiesis with lymphoid potential is essential for advancing human pluripotent stem cell (hPSC) technologies for the treatment of blood diseases and immunotherapies. In the embryo, lymphoid progenitors and hematopoietic stem cells (HSCs) arise from hemogenic endothelium (HE) lining arteries but not veins. Here, we show that activation of the arterial program through ETS1 overexpression or by modulating MAPK/ERK signaling pathways at the mesodermal stage of development dramatically enhanced the formation of arterial-type HE expressing DLL4 and CXCR4...

The aim of this study was to investigate the reproductive, biochemical, and hematological outcomes of pregnant rats exposed to protein restriction. Wistar rat dams were fed a control normal-protein (NP, 17% protein, n=8) or a low-protein (LP, 8% protein, n=14) diet from the 1st to the 20th day of pregnancy. On the 20th day, the clinical signs of toxicity were evaluated. The pregnant rats were then anesthetized and blood samples were collected for biochemical-hematological analyses, and laparotomy was performed to evaluate reproductive parameters...

With the development of new biologics and bioconjugates, storage and preservation have become more critical than ever before. Lyophilization is a method of cell and protein preservation by removing a solvent such as water from a substance followed by freezing. This technique has been used in the past and still holds promise for overcoming logistic challenges in safety net hospitals with limited blood banking resources, austere environments such as combat, and in mass casualty situations where existing resources may be outstripped...

Understanding the dynamics of red blood cell (RBC) motion under in-silico conditions is central to the development of cost effective diagnostic tools. Specifically, unraveling the relationship between the rheological properties and the nature of shape change in the RBC (healthy or infected) can be extremely useful. In case of malarial infection, RBC progressively loses its deformability and tends to occlude the microvessel. In the present study, detailed mesoscopic simulations are performed to investigate the deformation dynamics of a RBC in flow through a constricted channel...

Obesity in pregnant women has been associated with an increased risk of maternal complications, including gestational diabetes mellitus (GDM), a process that is related to oxidative stress (OS). To evaluate the biomarkers of OS in red blood cells (RBCs), we assigned 80 pregnant women to one of three groups: control (n = 28), overweight (n = 26) and obese (n = 26). Then, we measured in plasma, the levels of glucose, triacylglycerol (TAG), insulin, free fatty acids (FFAs), leptin and cytokines (e...

The management of major bleeding in patients treated with direct oral anticoagulants (DOACs) is still not well established. START-Events, a branch of the START registry (Survey on anTicoagulated pAtients RegisTer) (NCT02219984), aims to describe the actual management of bleeding or recurrent thrombotic events in routine clinical practice. We here present the results of the management of bleeding patients. The START-Event registry is a prospective, observational, multicenter, international study. Baseline characteristics (demographic, clinical, risk factors) of patients, laboratory data at admission and during follow-up, site of bleeding, therapeutic strategies, and outcomes at the time of hospital discharge and after 6 months were recorded on a web-based case report form...

Polycythemia vera (PV) is a myeloproliferative neoplasm characterized by overproduction of red blood cells. We have performed a comprehensive characterization of blood immune cells for expression of naïve and memory receptors as well as β2 m-associated and β2 m-free MHC class I heavy chains, also known as closed and open conformers, respectively, in PV patients and age-matched controls (CTR). We show that the peripheral CD3+ CD8+ T cell pool in PV patients is clearly divided into two discrete populations, a more granular CD3+ CD8high T cell population enriched in effector-memory CD45RA+ T cells (CD8+ TEMRA) when compared to CTR (P < 0...

Primary tumors of patients can release circulating tumor cells (CTCs) to flow inside of their blood. The CTCs have different mechanical properties in comparison with red and white blood cells, and their detection may be employed to study the efficiency of medical treatments against cancer. We present the design of a novel MEMS microgripper with rotatory electrostatic comb-drive actuators for mechanical properties characterization of cells. The microgripper has a compact structural configuration of four polysilicon layers and a simple performance that control the opening and closing displacements of the microgripper tips...

Disorders involving β-globin gene mutations, mainly β-thalassemia and sickle cell disease, represent a major target for hematopoietic stem/progenitor cell (HSPC) gene therapy. This includes CRISPR/Cas9-mediated genome editing approaches in adult CD34+ cells aimed toward the re-activation of fetal γ-globin expression in red blood cells. Because models involving erythroid differentiation of CD34+ cells have limitations in assessing γ-globin re-activation, we focused on human β-globin locus transgenic (β-YAC) mice...

PURPOSE: With the exception of neonatal respiratory failure, most centers are now using centrifugal over roller-type pumps for the delivery of extracorporeal membrane oxygenation (ECMO). Evidence supporting the use of centrifugal pumps specifically in infants with congenital diaphragmatic hernia (CDH) remains lacking. We hypothesized that the use of centrifugal pumps in infants with CDH would not affect mortality or rates of severe neurologic injury (SNI). METHODS: Infants with CDH were identified within the ELSO registry (2000-2016)...

Diamond like carbon (DLC) films were deposited onto Ti6Al4V and Si wafer substrates by RF plasma enhanced chemical vapor deposition. The influence of dopants such as fluorine (F), silicon (Si), and nitrogen (N) on composition, structure, and biocompatibility was investigated. Ion scattering spectroscopy analysis revealed the presence of dopant atoms in the outer-most layers of the films. Raman studies showed that the position of the G-band shifts to higher frequencies with the fluorine and nitrogen content in the DLC film, whereas the incorporation of Si into DLC induces a decrease of the position of the G peak...

Measuring red blood cell (RBC) deformability has become important for clinical disease diagnostics. Various methods for measuring RBC deformability have been developed; however, they require costly and large instruments, long measuring time, and skilled personnel. In this study, we present a three-dimensional-printed mini-disk (3D-PMD) for measuring RBC deformability to overcome the previous limitations. For a miniaturized and low-cost setup, the 3D-PMD was fabricated by a 3D printing technique, which had not yet been used for fabricating a lab-on-a-compact disk (LOCD)...
