We present rigorous solutions of scattering problems involving healthy red blood cells (RBCs) and diseased RBCs with deformed shapes. Scattering cross-section (SCS) values for different RBC shapes and different orientations are obtained accurately and efficiently using a sophisticated simulation environment based on the electric and magnetic current combined-field integral equation and the multilevel fast multipole algorithm. Using SCS values, we determine strict guidelines to distinguish deformed RBCs from healthy RBCs and to diagnose related diseases.

Computational study of scattering from healthy and diseased red blood cells
Ergül, Özgür Salih; Gurel, Levent (SPIE-Intl Soc Optical Eng, 2010-07-01)
We present a comparative study of scattering from healthy red blood cells (RBCs) and diseased RBCs with deformed shapes. Scattering problems involving three-dimensional RBCs are formulated accurately with the electric and magnetic current combined- field integral equation and solved efficiently by the multilevel fast multipole algorithm. We compare scattering cross section values obtained for different RBC shapes and different orientations. In this way, we determine strict guidelines to distinguish deformed...
Systematically organized nanopillar arrays reveal differences in adhesion and alignment properties of BMSC and Saos-2 cells
Ozcelik, Hayriye; Padeste, Celestino; Hasırcı, Vasıf Nejat (2014-07-01)
Polymeric test surfaces of P(L-D,L)LA and of a P(L-D,L)LA:PLGA blend decorated with 25 nanopillar covered fields, were used to investigate differences in growth of bone marrow stem cells (BMSC) and osteosarcoma cells (Saos-2). The fields were populated with pillars (ca. 900 nm tall, 200 nm x 200 nm area) separated systematically from each other with 1-10 mu m gaps. Saos-2 cells populated fields decorated with pillars 1 mu m apart but they avoided pillar-free surfaces. In contrast, BMSCs avoided fields with ...

Purpose Patients with heterozygous gain-of-function (GOF) mutations in STAT1 frequently exhibit chronic mucocutaneous candidiasis (CMC), immunodeficiency and autoimmune manifestations. Several treatment options including targeted therapies and hematopoietic stem cell transplantation (HSCT) are available for STAT1 GOF patients but modalities and outcomes are not well established. Herein, we aimed to unravel the effect of ruxolitinib as a bridge therapy in a patient with sporadic STAT1 T385M mutation to manag...
Examination of the dielectrophoretic spectra of MCF7 breast cancer cells and leukocytes
Çağlayan, Zeynep; Demircan Yalçın, Yağmur; Külah, Haluk (Wiley, 2020-03-01)
The detection of circulating tumor cells (CTCs) in blood is crucial to assess metastatic progression and to guide therapy. Dielectrophoresis (DEP) is a powerful cell surface marker-free method that allows intrinsic dielectric properties of suspended cells to be exploited for CTC enrichment/isolation from blood. Design of a successful DEP-based CTC enrichment/isolation system requires that the DEP response of the targeted particles should accurately be known. This paper presents a DEP spectrum method to inve...
Selenium status of healthy Turkish children
Mengubas, K; Diab, NA; Gokmen, IG; Ataman, Osman Yavuz; Cavdar, A; Cin, S (1996-08-01)
Selenium concentrations, in blood plasma, red blood cells, hair of 61 healthy children, ages 0-14 yr, were determined using hydride generation atomic absorption spectrometry Starting from late lactation period, selenium concentrations in all these matrices were found to be increasing with age. A good correlation was found between erythrocyte and plasma, hair and plasma, and hair and erythrocyte selenium concentrations. Although plasma, erythrocyte, and hair selenium concentrations of girls seemed to be high...
