1. Combination of heterologous fibrin sealant and bioengineered human embryonic stem cells to improve regeneration following autogenous sciatic nerve grafting repair
Abstract Background Peripheral nerve injury is a worldwide clinical problem, and the preferred surgical method for treating it is the end-to-end neurorrhaphy. When it is not possible due to a large nerve gap, autologous nerve grafting is used. However, these surgical techniques result in nerve regeneration at highly variable degrees. It is thus very importa

2. Treatment of intrabony defects with ABM/P-15 or GTR in patientes with agressive periodontitis: a Clinical, Radiographic and gingival fluid cytokines levels evaluation / Avaliação do uso de matriz óssea bovina inorgânica associada ao peptídeo de adesão celular no tratamento de defeitos infra-ósseos em pacientes com periodontite agressiva. Estudo clínico, radiográfico e laboratorial em humanos
Background: Intrabony periodontal defects present a particular treatment problem, especially in patients with Generalized Aggressive Periodontitis (G-AgP).Researches have been performed in order to improve the results of regenerative procedures. Material and Methods: The aim of this study was to compare outcomes of intrabony periodontal defects following tre

3. Erythrocytes in human transplantation: effects of pretreatment with ABO group-specific antigens
Erythrocyte group antigens A and B can act as potent and group-specific transplantation antigens in man. ABO group-incompatible recipients pretreated with such antigens have rejected skin allografts obtained from donors incompatible for the same antigens in an accelerated (4-5 days) or white graft manner. Skin grafts applied to the same recipients from ABO-c

4. Impaired serum antibody response to inactivated influenza A and B vaccine in renal transplant recipients.
Before and after vaccination with a commercial inactivated influenza vaccine containing A/Aichi/2/68 (H3N2) and B/Massachusetts/1/71 antigens, the serum hemagglutination inhibition antibody titers to homologous and heterologous strains of A and B influenza viruses were measured in 45 renal transplant patients and 66 healthy controls (62 for the B strains). A

5. Heterologous immunity provides a potent barrier to transplantation tolerance
Many strategies have been proposed to induce tolerance to transplanted tissue in rodents; however, few if any have shown equal efficacy when tested in nonhuman primate transplant models. We hypothesized that a critical distinction between specific pathogen-free mice and nonhuman primates or human patients is their acquired immune history. Here, we show that

6. Specificity of Infection-Induced Immunity among Borrelia burgdorferi Sensu Lato Species
The specificity of infection-induced immunity in mice infected with cultured or host-adapted Borrelia burgdorferi sensu lato, the agent of Lyme disease, was examined. Sera obtained from mice following infection with high and low doses of cultured B. burgdorferi sensu stricto, transplantation of infected tissue (host-adapted spirochetes), or tick-borne inocul

7. Rescue of ATPa3-deficient murine malignant osteopetrosis by hematopoietic stem cell transplantation in utero
Autosomal recessive osteopetrosis (ARO) is a paradigm for genetic diseases that cause severe, often irreversible, defects before birth. In ARO, osteoclasts cannot remove mineralized cartilage, bone marrow is severely reduced, and bone cannot be remodeled for growth. More than 50% of the patients show defects in the osteoclastic vacuolar-proton-pump subunit,

8. Comparison of Specific Serological Assays for Diagnosing Human Herpesvirus 6 Infection after Liver Transplantation
Cross-reactivity between human herpesvirus 6 (HHV-6) and human herpesvirus 7 (HHV-7) antibodies and the reliability of specific serological assays were analyzed for 12 patients with concurrent HHV-6 and HHV-7 antibody responses after transplantation with a liver from a living relative by using an immunofluorescence assay (IFA). A neutralizing antibody titer

9. Identification of negative and positive regulatory elements associated with a class I major histocompatibility complex gene.
Regulatory DNA sequence elements were functionally identified in the 5'-flanking region of a gene, PD1, which encodes a porcine classical transplantation antigen. Both a positive regulatory element and a novel negative regulatory DNA element were mapped within 1.1 kilobases upstream of exon 1. The negative regulatory element reduced the activity of both the

10. In vitro isolation of stable rat sarcoma viruses
A Sprague-Dawley (SD-1) rat embryo culture, at low passage level, released an endogenous ecotropic type C virus (SD-RaLV) and after about 20 further passages it underwent spontaneous transformation. The SD-RaLV, released from the transformed cells, did not cause rapid transformation of other rat embryo cells. However, when the transformed cells were repeated

11. Stable transfer and restricted expression of a cloned class I gene encoding a secreted transplantation-like antigen.
The identification of a unique major histocompatibility complex class I gene, designated Q10, which encodes a secreted rather than a cell surface antigen has led to questions regarding its potential role in regulating immunological functions. Since the Q10 gene is specifically activated only in the liver, we sought to define the molecular mechanisms which co

12. Chemical camouflage of antigenic determinants: Stealth erythrocytes
In a number of clinical circumstances it would be desirable to artificially conceal cellular antigenic determinants to permit survival of heterologous donor cells. A case in point is the problem encountered in transfusions of patients with rare blood types or chronically transfused patients who become allosensitized to minor blood group determinants. We have
