Studying Red Blood Cell Agglutination By Measuring Membrane Viscosity With Optical Tweezers
No full textThe red blood cell (RBC) viscoelastic membrane contains proteins and glycoproteins embedded in a fluid lipid bilayer that are responsible for cell agglutination. Manipulating RBCs rouleaux with a double optical tweezers, we observed that the cells slide easily one over the others but are strongly connected by their edges. An explanation for this behavior could be the fact that when the cells slide one over the others, proteins are dragged through the membrane. It confers to the movement a viscous characteristic that is dependent of the velocity between the RBCs and justifies why is so easy to slide them apart. Therefore, in a first step of this work, by measuring the force as a function of the relative velocity between two cells, we confirmed this assumption and used this viscous characteristic of the RBC rouleaux to determine the apparent membrane viscosity of the cell. As this behavior is related to the proteins interactions, we can use the apparent membrane viscosity to obtain a better understanding about cell agglutination. Methods related to cell agglutination induced by antigen-antibody interactions are the basis of most of tests used in transfusion centers. Then, in a second step of this work, we measured the apparent membrane viscosity using antibodies. We observed that this methodology is sensitive to different kinds of bindings between RBCs. Better comprehension of the forces and bindings between RBCs could improve the sensibility and specificity of the hemagglutination reactions and also guides the development of new potentiator substances.6644Fontes, A., Fernandes, H.P., Barjas-Castro, M.L., Thomaz, A.A., Pozzo, L., Barbosa, L.C., Cesar, C.L., Red blood cell membrane viscoelasticity, agglutination and zeta potential measurements with double optical tweezers (2006) Proceedings of SPIE, 6088, pp. 296-305Eylar, E.H., Madoff, M.A., Brody, O.V., Oncley, J.L., The contribution of sialic acid to the surface charge of the erythrocyte (1962) J.

Monitoring Activity Of Living Cells Marked With Colloidal Semiconductor Quantum Dots
No full textFluorescent semiconductor nanocrystals in quantum confinement regime (quantum dots) present several well known features which make them very useful tools for biological labeling purposes. Low photo-bleaching rates, high chemical stability, active surface allowing conjugation to living cells, explains the success of this labeling procedure over the commonly used fluorescent dyes. In this paper we report the results obtained with high fluorescent core-shell CdTe-CdS (diameter = 3-7 nm) colloidal nanocrystals synthesized in aqueous medium and conjugated to glucose molecules, incubated with living yeast cells, in order to investigate their glucose up-take activity.6088Menezes, F.D., Brasil Jr., A.G., Moreira, W.L., Barbosa, L.C., Ferreira, R.C., Cerar, C.L., Farias, P.M.A., Santos, B.S., (2005) Microelectronics Journal, 36, pp. 989-991Alivisatos, A., (1996) J.

Detection Of Metabolic Syndrome Features Among Childhood Cancer Survivors: A Target To Prevent Disease
No full textAlong with the growing epidemic of obesity, the risk of atherosclerosis, cardiovascular disease morbidity, and mortality are increasing markedly. Several risk factors for cardiovascular disease, such as visceral obesity, glucose intolerance, arterial hypertension, and dyslipidemia commonly cluster together as a condition currently known as metabolic syndrome. Thus far, insulin resistance, and endothelial dysfunction are the primary events of the metabolic syndrome. Several groups have recommended clinical criteria for the diagnosis of metabolic syndrome in adults. Nonetheless, in what concerns children and adolescents, there are no unified definitions, and modified adult criteria have been suggested by many authors, despite major problems. Some pediatric disease states are at risk for premature cardiovascular disease, with clinical coronary events occurring very early in adult life. Survivors of specific pediatric cancer groups, particularly acute lymphocytic leukemia, central nervous system tumors, sarcomas, lymphomas, testicular cancer, and following bone marrow transplantation, may develop metabolic syndrome traits due to: hormonal deficiencies (growth hormone deficiency, thyroid dysfunction, and gonadal failure), drug or radiotherapy damage, endothelial impairment, physical inactivity, adipose tissue dysfunction, and/or drug-induced magnesium deficiency. In conclusion, some primary and secondary prevention remarks are propose in order to reduce premature cardiovascular disease risk in this particular group of patients. © 2008 Siviero-Miachon et al, publisher and licensee Dove Medical Press Ltd.44825836Adan, L., Trivin, C., Sainte-Rose, C., GH deficiency caused by cranial irradiation during childhood: Factors and mukers in young adults (2001) J Clin Endocrinol Metab, 86, pp. 5245-5251Ahmet, A., Blaser, S., Stephens, D., Weight gain in craniopharyngioma -a model for hypothalamic obesity (2006) J Pediatr Endocrinol Metab, 19, pp. 121-128Alberti, K.G.M.M., Zimmet, P.Z., World Health Organisation (WHO)-Definition, diagnosis and classification of diabetes mellitus and its complications.

Gait Variability and Kinematic Alterations in People with Diabetes Mellitus and Peripheral Neuropathy
No full textBackground: People with diabetes and peripheral neuropathy have been reported to show alterations in lower limb joint function compared to healthy non-diabetic people. Specifically the maximum angular movement available at certain joints can be reduced during static, non-weight bearing tasks. Limited joint range of motion has the potential to compromise balance and stability thereby increasing the risk of falling. It is unclear whether a reduction in the extent of movement available at the joints is reflected by a reduction in the amount of angular movement actually utilised during a functional task such as stair negotiation. The aim of this study was to determine if people with diabetes show reduced dynamic range of motion at the ankle, knee and hip joints during stair ascent and descent in comparison to controls. Falls risk during stair negotiation was calculated by measuring the degree of variability in dynamic joint range of motion. Methods: Data were generated from three groups: subjects with diabetes and peripheral neuropathy (DPN), diabetes without peripheral neuropathy (DM), and healthy controls (Ctl). The study was conducted in a gait laboratory using motion capture and related 3D software for analysis. Joint range of motion for the ankle, knee, and hip were captured during level walking, stair ascent, and descent. A seven step, bespoke staircase was fabricated for this purpose. Analysis of Variance (ANOVA) and Newman-Keuls tests were used to analyse the data. Results: Significantly reduced ankle range of motion, in the sagittal plane, was observed in the DPN group during stair ascent when compared to the controls. For stair descent, the DPN group demonstrated a significant increase in knee and hip ROM in the frontal plane, and also hip ROM in the transverse plane. No significant differences between the groups were identified for joint variability. Conclusions: People with DPN demonstrate alterations in dynamic range of motion at the lower limb joints during stair ascent and descent. The degree of angular movement utilised for both stair tasks was decreased at the ankle joint and this has the potential to undermine balance and stability. In contrast, angular movement at the knee and hip joints was increased in the frontal and transverse planes. This may compensate for impaired balance and stability by increasing the base of support to maintain balance and assist in foot clearance and placement. The specific combination of increased angular movement at the knee and hip may represent a compensatory stair gait strategy in response to reduced angular movement at the ankle joint

First observation of Bs → J/ψf0(980) decays
No full textUsing data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively
