Abstract:
ABSTRACT We have analyzed three cases of hepatitis C virus (HCV)-infected recipients who received blood from HCV-infected donors. Two recipients were exposed to two different HCV RNA-positive donors, and one was exposed to a single donor. All parental genomes from the actual infecting units of blood and the recipients were defined, and their presence in the follow-up serum samples was determined using sensitive strain-specific assays. The strain from one of the donors was found to predominate in all recipients' serum samples collected throughout the follow-up period of 10 to 30 months. In two

SummaryThere is increasing evidence fora relationship between bacterial infections and several cardiovascular disorders. Although the precise mechanism(s) underlying this association is unknown, the direct activation of platelets by bacteria is one possibility. Individual strains of S. sanguis activate platelets in a non-uniform, donor-dependent manner. In the current study, platelet aggregation profiles were obtained for fourteen donors in response to four strains of S. sanguis (2017–78, 133–79, SK112, SK108a) and one of S. gordonii (SK8).

Based on a common biological phenomenon — homologous recombination — a novel method was developed by transferring chromosome DNA fragments extracted from multiple donor cells into a host strain. Through this method of transferring DNA fragments, foreign DNA fragments are introduced into one host cell and multiple positive traits from multiple strains may be integrated into the host strain. We first confirmed its feasibility in both prokaryotic and eukaryotic cells by selecting reverse mutants to prototrophy from auxotrophic strains through receiving chromosomal DNA fragments of wild-type paren

Abstract:
The chapters in this book demonstrate how transnational connections in Africa often appear as a source of ambiguity in formations that otherwise are ideologically perceived as bounded, autonomous entities. The experience of the transnational is often fraught with sentiments, ranging from fear to fascination, from anxiety to hope and aspiration. Given this dynamic of both anxiety about and eagerness for engaging in transnational relations, the Epilogue argues that there is a socially felt need among religious groups in many African societies for developing a transnational competence, especially in the sensitive field of HIV/AIDS, in order to successfully manage engagement with transnational relations and connections. This is grounded in the experience that, on the one hand, transnational connections have indeed allowed local people, organisations and institutions to make big steps forward in using religious linkages in the fight against AIDS and in changing notions of sexuality. Yet, on the other hand, while these connections are often being celebrated locally, the Epilogue argues that the enormous strains transnational relations can create for the local communities and organisations to live up to the expectations of external partners, donors and policies, should not be overlooked.

Chapter 1 examines how suffragists recruited wealthy women to the woman suffrage movement, who these donors were, and why they decided to give their money—and sometimes their time—to fight for political equality. This chapter argues that focusing on their feminism highlights a strand of suffragism that called for gender equality rather than emphasized maternalism, the belief that women as mothers (or potential mothers) had the right and the duty to vote in order to protect children and clean up government. Having experienced both the power of money and its limitations influenced the way women linked economic independence and political equality, which they believed were necessary whether one earned wages in a factory, was a professional with a college degree, or inherited a large fortune. Susan B. Anthony had understood that their donations were necessary, and Alva Belmont and Katharine McCormick gave donations essential to winning the right to vote for women.

Abstract:
This chapter distinguishes two accounts of how and why areas of law are individuated. The first view, ‘conventionalism’, says that individuation serves epistemic ends. Conventionalists claim that legal officials carve up areas of law to promote the rule of law by making it more digestible, easier to follow, handle, and so on. In contrast, the second view, ‘foundationalism’, is a metaphysical interpretation of the practice. Foundationalists claim that individuation is part of the very fabric of law. On this view, areas of law track basic moral principles or categories, such as promise, corrective justice, and so on, which shape and structure legal norms. Having claimed in Chapter 3 that foundationalism—in the guise of the ‘promise theory’—fails as an account of contract law, this chapter argues that conventionalism is not the only alternative. Instead, a third possibility—‘republicanism’—is explored, which the chapter calls ‘republicanism’. Ronald Dworkin argued that legal categories are connected with ‘positive morality’ or popular views about the moral principles, categories, and distinctions that legal categories implicate. This serves the purpose of involving ordinary citizens in legal and political decision-making about matters of principle that are usually the preserve of the courts. This reveals a very often overlooked republican strand to his legal theory, which opens the door to a ‘bottom-up’ theory of contract law more sensitive to the multiplicity of moral values and concerns that shape its rules and doctrines in particular jurisdictions and times.

"Since blood transfusion is linked to the magnitude of the surgical procedure, comparing transfused patients to untransfused patients will always be confounded by infection risks due to factors related to the procedure. To control for these factors one must compare patients transfused with red cells from different sources or prepared in a manner which minimize infection risk. Patients transfused with homologous blood have infection rates several fold higher than recipients of equal values of autologous blood undergoing the same operative procedure (20-23). Homologous blood recipients have significantly longer hospital stays attributed to treating infections. The cost of a blood transfusion exceeds the cost of collection, storage and administration because of transfusion's association with length of stay. In this era of cost-containment the association with prolonged stay may ultimately curtail the use of blood. Homologous blood can be filtered to remove donor leukocytes which may be contributing to immune suppression and infection risk. A prospective randomized trial comparing the infection rates among colorectal cancer patients receiving filtered and unfiltered blood has been conducted (9). There were 17 infectious complications among the 56 recipients of whole blood and one infectious complication among the 48 recipients of filtered blood. Infections were prevented by the seemingly simplistic addition of a $25/filter to every bag of blood transfused. These clinical studies are very convincing: homologous blood transfusion is associated with increased risk of infection in every clinical situation examined. In multivariate analyses transfusion was a significant predictor of infection after consideration of other variables measured and in the majority of those studies transfusion was the single most significant factor. Patients receiving homologous blood exhibited an incidence of infectious complications that was approximately four times higher than patients receiving autologous blood. The association of transfusion with infection is found among patients undergoing surgery for cardiac, orthopedic and gastrointestinal disorders and for trauma as well as among unoperated patients transfused for bums and gastrointestinal bleeding. The observation that nosocomial infections are increased in these studies argues strongly that the association of transfusion with infection is not simply a reflection of transfusion as a marker of tissue destruction and contamination. Infections that develop in transfused patients away from the site of trauma or in the absence of trauma, cannot be attributed to the quantity of tissue destroyed or to the degree of bacterial contamination. Filtered blood can remove leukocytes and prevent postoperative infections. Since filtering blood can significantly reduce the incidence of infection among transfused patients, all transfused blood will be passing through filters in the very near future. EXPERIMENTAL STUDIES RELATING BLOOD TRANSFUSION TO INCREASED RISK OF INFECTION Patients are extremely heterogeneous and even in prospective randomized trials, factors which influence patients' participation affect the outcome despite double-blinding and randomization. In animal studies using syngeneic strains with identical housing, lighting, access to food and water, control over the extent of injury, use of antibiotics and exposure to other variables the influence of a single variable such as blood transfusion can be measured.

The vessel was fabricated under Code Case 2564 of the ASME Boiler and Pressure Vessel Code, which provides rules for the design of impulsively loaded vessels. The explosive rating for the vessel, based on the Code Case, is nine (9) pounds TNT-equivalent for up to 637 detonations, limited only by fatigue crack growth calculations initiated from a minimum detectable crack depth. The vessel consists of a cylindrical cup, a flat cov

Abstract This study aims to biomechanically compare four different treatment methods for repair enhancement in Achilles tendon rupture in rats: collagen, collagen and platelet-rich plasma (PRP), collagen and mesenchymal stromal cells (MSC), and a combination of collagen, platelet-rich plasma and mesenchymal stromal cells (CPM) at one and two week healing periods. This study included ninety Lewis rats weighing approximately 200–300 g. Ten rats were used as donors for MSC and PRP. For the remaining eighty rats, the right leg was completely transected 6 mm proximal to the calcaneus bone, suture r

Abstract:
Unexpected findings on time and temperature dependent behavior have been recorded during our research on fatigue performance of niobium stabilized stainless steel. Cyclic straining at 325°C and low strain rates resulted in higher stress responses than in higher rate tests. This effect is particular strong in PWR water environment. Subsurface bulk effect in environment is in contrast to the assumption on similar responses in air and environment, which is the foundation of the ‘companion specimen’ method where the strain in environment is measured from a parallel specimen similarly tested in air
