Differential tuning of the electron transfer parameters in 1,3,5-triarylpyrazolines: a rational design approach for optimizing the contrast ratio of fluorescent probes. | A large class of cation-responsive fluorescent sensors utilizes a donor-spacer-acceptor (D-A) molecular framework that can modulate the fluorescence emission intensity through a fast photoinduced intramolecular electron transfer (PET) process. The emission enhancement upon binding of the analyte defines the contrast ra... | 18,767,839 |
Formal synthesis of (-)-kendomycin featuring a Prins-cyclization to construct the macrocycle. | The kendomycin skeleton was prepared by a highly convergent strategy in which the benzofuran fragment and the acyclic iodide fragment were prepared by standard methods and joined using a Suzuki coupling.

G--C quartet--a DNA-inspired Janus-GC heterocycle: synthesis, structural analysis, and self-organization. | In this communication we disclose the synthesis and characterization of a DNA-inspired self-complementary heterocycle that contains AAD-DAA H-bond acceptor/donor patterns. Whereas in the past such AAD-DAA self-complementarity has given rise to trimeric and hexameric rosettes, we now demonstrate that the same H-bonding ... | 18,767,852 |
Femtonewton force sensing with optically trapped nanotubes. | We extract the distribution of both center-of-mass and angular fluctuations from three-dimensional tracking of optically trapped nanotubes. We measure the optical force and torque constants from autocorrelation and cross-correlation of the tracking signals. This allows us to isolate the angular Brownian motion. We demo... | 18,767,887 |
Revision rates after primary hip and knee replacement in England between 2003 and 2006. | Hip and knee replacement are some of the most frequently performed surgical procedures in the world. Resurfacing of the hip and unicondylar knee replacement are increasingly being used. There is relatively little evidence on their performance. To study performance of joint replacement in England, we investigated revisi... | 18,767,900 |
Concepts and categories: a cognitive neuropsychological perspective. | One of the most provocative and exciting issues in cognitive science is how neural specificity for semantic categories of common objects arises in the functional architecture of the brain. More than two decades of research on the neuropsychological phenomenon of category-specific semantic deficits has generated detaile... | 18,767,921 |
PR1 vaccination in myeloid malignancies. | The graft-versus-leukemia (GVL) effect following allogeneic stem cell transplantation is testament to the effectiveness of the immune system in recognizing and eliminating leukemia cells. The successful identification of a range of leukemia-associated antigens (LAAs) that drive the GVL response in recent years has stim... | 18,767,937 |
Strategies used for MUC1 immunotherapy: preclinical studies. | The development of effective immunotherapeutic approaches against cancer has been a major focus of research in the last 10-15 years. Despite the impressive progress in the last 10 years, which has incorporated purified proteins, DNA and targeting to dendritic cells and/or the use of Toll-like receptor ligands, there ar... | 18,767,945 |
EGF receptor variant III as a target antigen for tumor immunotherapy. | The EGF receptor (EGFR) is the first tyrosine kinase receptor ever cloned and remains at the forefront of targeted therapies against cancer. Currently, there are four US FDA-approved drugs and several more in Phase III studies that target the EGFR. These drugs, while resulting in some dramatic remissions, have not resu... | 18,767,947 |
Heat-shock proteins in cancer vaccines: agents of antigen cross-presentation. | Heat-shock proteins (HSPs) derived from tumors are capable of eliciting an anticancer immune response by facilitating antigen cross-presentation in antigen-presenting cells (APCs). This process involves the ability of such chaperones to bind tumor antigens and facilitate their uptake by APCs. Recent evidence reveals th... | 18,767,951 |
Promises and challenges for the development of Listeria monocytogenes-based immunotherapies. | Active immunotherapy has shown great promise in preclinical models for the treatment of infectious and malignant disease. Yet, these promising results have not translated into approved therapies. One of the major deficits of active immunotherapies tested to date in advanced clinical studies has been their inability to ... | 18,767,955 |
Promising particle-based vaccines in cancer therapy. | Immunotherapy and preventative cancer vaccines offer the hope of controlling cancer in humans with few of the undesirable side effects associated with current chemotherapy-based methods. Particulate vaccines are effectively taken up by dendritic cells, inducing both T-cell and antibody responses. Virus-like particles (... | 18,767,957 |
A large Escherichia coli O157 outbreak in Sweden associated with locally produced lettuce. | In 2005 a large outbreak of verotoxin-producing Escherichia coli (VTEC) occurred in Sweden. Cases were interviewed and cohort and case-control studies were conducted. Microbiological investigations were performed using polymerase chain reaction (PCR) to detect the Shiga-like toxin (Stx) genes followed by cultivation an... | 18,767,979 |
Changes in beta(1) integrin in renal tubular epithelial cells after intrauterine asphyxia of rabbit pups. | We investigated the role of beta(1) integrin in acute renal tubular injury caused by intrauterine asphyxia of neonatal rabbits by exploring the distribution and expression changes in beta(1) integrin and its mRNA in renal tubular epithelial cells. A catheter was used to temporarily block the abdominal aortas of New Zea... | 18,767,988 |
