Assays for quality control of platelets for transfusion

Quality control of platelets relies on the determination of the extent by which platelets are still able to react with known agonists, and here knowledge of the biochemistry of platelet activation may guide to decide which tests are useful. In vivo, platelets will adhere to collagen exposed upon vessel wall damage, and especially under high shear conditions through von Willebrand factor (VWF) that forms a bridge between collagen and platelet glycoprotein (GP) Ib. Binding of GPVI to collagen next results in the activation of a tyrosine kinase cascade, finally resulting in phosphorylation and activation of phospholipase C (PLC) γ2, which leads to an increase in cytosolic Ca²⁺ levels. High Ca²⁺ levels trigger the production of thromboxane A2 (TXA2) and release of platelet granules containing among others, adenosine diphosphate (ADP). TXA2 and ADP now will activate their receptors on platelets which are, among others, linked to a G-protein that activates PLCβ2 with more Ca²⁺ increase. This ultimately provokes activation of the integrin α_IIbβ₃ (or GPIIbIIIa), which now can bind the symmetrical fibrinogen, thus allowing cross-linking of platelets or platelet aggregation. From the above it is clear that testing whether platelets are fully reactive ideally should be looking at as many of the above parameters as possible, while at the same time being simple and fast. Systems in which blood is flown over collagen surfaces mimic best the physiological situation; however, these tests are not fit for stored platelet testing as haematocrit is a critical factor in these experiments. Thromboelastography at best provides a test for G-protein dependent activation (through thrombin) and integrin α_IIbβ₃ involvement. Platelet agglutination induced by ristocetin (surrogate for the adhesion phase) next to aggregation (involvement of integrin α_IIbβ₃) induced by collagen (Tyr kinase pathway) and ADP (G-protein mediated pathway) can give a comprehensive view on the platelet quality. However, flow cytometry is also an excellent technique to detect (i) bound VWF to platelets in the presence of ristocetin, (ii) collagen- or ADP-induced activation of integrin α_IIbβ₃ (by determining the binding of fibrinogen or of the activation-dependent PAC-1 antibody) and (iii) secretion (by detecting surface expression of P-selectin).     

Comparison of Blocking Agents for an Elisa for Lps

ELISA is a sensitive, specific, reproducible and fast method for detection of antigen-antibody reactions. in case of non-protein antigens as LPS, problems exist, such as poor proportion of coating to microplates, non-specific binding of antibodies to the plastic wells. These problems were resolved partially by Takahashi and co-workers using poly-L-lysine for coating of LPS antigens. to reduce non-specific binding, blocking agent, such as bovine serum albumin (BSA) or casein is commonly used. We have to choose the blocking agent carefully because LPS can bind proteins non-specifically. This process can inhibit binding of LPS-specific antibody to LPS and decrease the sensitivity of method. in this paper we describe an ELISA test for LPS in which normal goat serum is used for blocking. This modification increases the sensitivity of ELISA. This method is useful for detection of LPS (S, R form) and anti-LPS antibody reaction in serological cross-reaction studies.     

Criteria for aspiration cytology for the diagnosis of seminoma

Fine-needle aspiration cytology was performed in two cases of intra-abdominal tumors, one from retroperitoneal lymph nodes and one from a cryptorchid testis. The cytological diagnosis was consistent with seminoma in both cases. Cytological features included uniform neoplastic malignant cells with round nuclei and nucleoli. The cytoplasm, easily observed on May-Grünwald-Giemsa-stained smears, contained large vacuoles or lacunes filled with glycogen. Alkaline phosphatase activity was strictly located to one cytoplasmic area of the cells. This cytological and cytoenzymatic pattern is different from that observed in other intra-abdominal tumors, including adenocarcinoma, large-cell lymphoma, and embryonal carcinoma.     

Criteria for the Selection of Materials for Implanted Electrodes

There are four criteria that must be considered when choosing material for an implanted electrode: (1) tissue response, (2) allergic response, (3) electrode-tissue impedance, and (4) radiographic visibility. This paper discusses these four criteria and identifies the materials that are the best candidates for such electrodes. For electrodes that make ohmic contact with tissues: gold, platinum, platinum–iridium, tungsten, and tantalum are good candidates. The preferred insulating materials are polyimide and glass. The characteristics of stimulator output circuits and the importance of the bidirectional wave- form in relation to electrode decomposition are discussed. The paper concludes with an analysis, the design criteria, and the special properties and materials for capacitive recording and stimulating electrodes. © 2003 Biomedical Engineering Society.
