Rationally designed beta-sheet-forming peptides that spontaneously form three-dimensional fibrillar scaffolds in response to specific environmental triggers may potentially be used in skeletal tissue engineering, including the treatment/prevention of dental caries, via bioactive surface groups. We hypothesized that infiltration of caries lesions with monomeric low-viscosity peptide solutions would be followed by in situ polymerization triggered by conditions of pH and ionic strength, providing a biomimetic scaffold capable of hydroxyapatite nucleation, promoting repair. Our aim was to determine the effect of an anionic peptide applied to caries-like lesions in human dental enamel under simulated intra-oral conditions of pH cycling. Peptide treatment significantly increased net mineral gain by the lesions, due to both increased remineralization and inhibition of demineralization over a five-day period. The assembled peptide was also capable of inducing hydroxyapatite nucleation de novo. The results suggest that self-assembling peptides may be useful in the modulation of mineral behavior during in situ dental tissue engineering. 相似文献

The aim was to evaluate the association of molecular-level human leukocyte antigen (HLA) mismatching with post-transplant graft survival, rejection, and cardiac allograft vasculopathy (CAV). We retrospectively analyzed all primary cardiac transplant recipients between 01/1984-06/2016. 1167 patients fulfilled inclusion criteria and had HLA typing information available. In 312 donor-recipient pairs, typing at serological split antigen level was available. We used the Epitope MisMatch Algorithm to calculate the number of amino acid differences in antibody-verified HLA eplets (amino acid mismatch load (AAMM)) between donor and recipient. Patients with a higher HLA-DR AAMM load had inferior 1-year graft survival (hazard ratio [HR], 1.14; 95% confidence interval [CI], 1.01–1.28). The HLA-AB AAMM load showed no impact on graft survival. In the subgroup with available split-level information, we observed an inferior graft survival for a higher HLA-DR AAMM load 3 months after transplantation (HR, 1.22; 95% CI, 1.04–1.44) and a higher risk for rejection for an increasing HLA-AB (HR, 1.70; 95% CI, 1.29–2.24) and HLA-DR (HR, 1.32; 95% CI, 1.09–1.61) AAMM load. No impact on the development of CAV was found. Molecular-level HLA mismatch analysis could serve as a tool for risk stratification after heart transplantation and might take us one step further into precision medicine. 相似文献

Guidelines recommend vaccination starting 12 months after autologous hematopoietic stem cell transplant (aHCT), but there is varying practice for patients on maintenance therapy, with some centers not immunizing at all. Because of decreased vaccine rates among the general population causing loss of herd immunity, we aimed to establish the safety and efficacy of revaccinating multiple myeloma patients on lenalidomide maintenance (LM). Of the 122 patients who were vaccinated after aHCT between 2010 and 2014 at Memorial Sloan Kettering Cancer Center, 91 (75%) were on LM. Vaccine responses were defined by increases between pre- and postvaccination titers. Reponses varied by vaccine type with 76% responding to pertussis, 70% diphtheria, 60% tetanus, 71% Haemophilus influenzae, and 58% pneumococcal. All patients retained minimal levels of polio immunity, but 27% responded with increased titers. Fewer patients received hepatitis A and B, but of those who did, 30% responded to hepatitis A and 40% to hepatitis B. No differences were seen in rates of response for those on LM at time of vaccination compared with those who were not. There were no vaccine-related adverse effects. Reimmunization with inactivated vaccines in patients on LM is therefore both safe and effective, offering this population immunity to vaccine-preventable diseases. 相似文献

Hepatic and renal metabolism before and after portasystemic shunts in patients with cirrhosis. 总被引:1,自引:0,他引:1 下载免费PDF全文

Hepatic cirrhosis with portal hypertension and gastroesophageal hemorrhage is a disease complex that continues to be treated by surgical portasystemic shunts. Whether or not a reduction or diversion of portal blood flow to the liver adversely affects the ability of the liver to maintain fuel homeostasis via gluconeogenesis, glycogenolysis, and ketogenesis is unknown. 11 patients with biopsy-proven severe hepatic cirrhosis were studied before and after distal splenorenal or mesocaval shunts. Hepatic, portal, and renal blood flow rates and glucose, lactate, pyruvate, glycerol, amino acids, ketone bodies, free fatty acids, and triglyceride arteriovenous concentration differences were determined to calculate net precursor-product exchange rates across the liver, gut, and kidney. The study showed that hepatic contribution of glucose and ketone bodies and the caloric equivalents of these fuels delivered to the blood was not adversely affected by either a distal splenorenal or mesocaval shunt. In addition to these general observations, isolated findings emerged. Mesocaval shunts reversed portal venous blood and functionally converted this venous avenue into hepatic venous blood. The ability of the kidney to make a substantial net contribution of ketone bodies to the blood was also observed. 相似文献

Bone metastases are usually associated with a variety of skeletal related events (SREs), a term covering both complications (pathological fractures, spinal cord compression) and the need for therapeutic intervention (radiotherapy, surgery to bone) for painful bone lesions and/or lesions carrying a high risk of fracture by which the patient's quality of life, functioning, and independence may be compromised. In view of the availability of improved therapeutic approaches for oncological diseases and the resulting improvements of median overall survival, the aim of preventing and delaying the occurrence of SREs becomes more important. To avoid, wherever possible, therapies requiring hospitalization, is another relevant goal. In recent years, bisphosphonates, along with available tumor-specific medication (chemotherapy, hormone therapy), constituted the standard of care for preventing skeletal complications in treating patients with bone metastases. Recently, a therapeutical alternative with potentially superior efficacy has been found in denosumab, a fully human monoclonal antibody that binds to the receptor activator of nuclear factor-κB ligand (RANKL), thus preventing osteoclast-mediated bone resorption and specifically interfering with bone metabolism. 相似文献

Cultured explants from early postnatal mouse cerebellum were used to examine the influence of a 43-kDa glia-derived neurite-promoting factor (GdNPF) on the migration of [3H]thymidine-labeled granule cell neurons. GdNPF, which is a potent serine protease inhibitor, significantly reduced the extent of granule cell migration in a dose-dependent manner. This effect could be neutralized by addition of thrombin, which binds GdNPF. Other protease inhibitors such as aprotinin, hirudin, soybean trypsin inhibitor, leupeptin, 6-aminocaproic acid, and D-Phe-Pro-ArgCH2Cl do not show this inhibitory effect. These results demonstrate that a glia-derived protein can regulate the migration of postmitotic neurons, an important cellular event in the development of the nervous system. 相似文献
