Biology and treatment of malignant glioma. (1998)

A large number of oncogenes have been identified as aberrant in gliomas, but only the erbB oncogene (gene encoding the epidermal growth factor receptor [EGFR]) is amplified in an appreciable number. The loss or mutation of tumor-suppressor genes located on different autosomes may be associated with progression of malignant gliomas. The p53 tumor-suppressor gene (located on chromosome 17) is frequently associated with the loss of one allele in malignant gliomas, although a large number of malignant gliomas have no p53 mutations. Some of the latter tumors have an amplified murine double minute 2 (MDM2) gene, which suppresses p53 gene activity. Genetic material from chromosome 10 may also be lost, especially in glioblastoma multiforme. In addition to the aberrant expression of EGFR, another growth factor, platelet-derived growth factor, or PDGF (ligand and/or receptors) can be overexpressed, giving cells a selective growth advantage. The blood-brain barrier is substantially altered in malignant gliomas, resulting in cerebral edema. Therapy for malignant gliomas includes surgery, radiation therapy, and chemotherapy. Surgical resection that leaves little residual tumor produces longer survival than less vigorous surgery. Radiation therapy to a dose of at least 60 Gy is required to treat malignant gliomas. Increased survival beyond that produced by standard external radiotherapy requires much larger doses; interstitial radiotherapy permits such dosing. Radiosurgery is being tested. Chemotherapy with nitrosoureas is modestly useful but appears to benefit patients with anaplastic astrocytoma more so than those with glioblastoma.
StarTrack (2009)

Mobile devices are increasingly equipped with hardware and software services allowing them to determine their locations, but support for building location-aware applications remains rudimentary. This paper proposes tracks of location coordinates as a high-level abstraction for a new class of mobile applications including ride sharing, location-based collaboration, and health monitoring. Each track is a sequence of entries recording a person's time, location, and application-specific data. StarTrack provides applications with a comprehensive set of operations for recording, comparing, clustering and querying tracks. StarTrack can efficiently operate on thousands of tracks.
[Treatment of recurrent Clostridium difficile-associated diarrhoea with a suspension of donor faeces]. (2008)

Treatment with donor faeces seems promising for patients who develop repeated recurrences despite adequate therapy and could be valuable in the future during (local) epidemics of the PCR ribotype 027 strain. A randomised nationwide study (FECAL trial) has been started in order to determine the efficacy of this treatment.
Neutrophil Recruitment by Human IL-17 Via C-X-C Chemokine Release in the Airways (1999)

IL-17 is a recently discovered cytokine that can be released from activated human CD4+ T lymphocytes. This study assessed the proinflammatory effects of human (h) IL-17 in the airways. In vitro, hIL-17 increased the release of IL-8 in human bronchial epithelial and venous endothelial cells, in a time- and concentration-dependent fashion. This effect of hIL-17 was inhibited by cotreatment with an anti-hIL-17 Ab and was potentiated by hTNF-alpha. In addition, hIL-17 increased the expression of hIL-8 mRNA in bronchial epithelial cells. Conditioned medium from hIL-17-treated bronchial epithelial cells increased human neutrophil migration in vitro. This effect was blocked by an anti-hIL-8 Ab. In vivo, intratracheal instillation of hIL-17 selectively recruited neutrophils into rat airways. This recruitment of neutrophils into the airways was inhibited by an anti-hIL-17 Ab and accompanied by increased levels of rat macrophage inflammatory protein-2 (rMIP-2) in bronchoalveolar lavage (BAL) fluid. The BAL neutrophilia was also blocked by an anti-rMIP-2 Ab. The effect of hIL-17 on the release of hIL-8 and rMIP-2 was also inhibited by glucocorticoids, in vitro and in vivo, respectively. These data demonstrate that hIL-17 can specifically and selectively recruit neutrophils into the airways via the release of C-X-C chemokines from bronchial epithelial cells and suggest a novel mechanism linking the activation of T-lymphocytes to recruitment of neutrophils into the airways.
Anti-CGRP Monoclonal Antibodies: the Next Era of Migraine Prevention? (2017)

Migraine is a very disabling disorder with severe impact on patients' lives and substantive costs to society in terms of healthcare costs and lost productivity. Prevention is a key component of migraine therapy, and while numerous preventive options exist, each is burdened by either troublesome side effects or insufficient efficacy. All migraine preventives currently in clinical use were licensed for other purposes and, by chance, have efficacy against migraine. As our understanding of migraine has evolved, calcitonin gene-related peptide (CGRP) has moved to the forefront as a neuropeptide central to migraine pathophysiology. Six small molecule CGRP receptor antagonists were shown to be effective for acute treatment of migraine; two were stopped for hepatotoxicity or one for formulation concern issues and one is now in phase III. Monoclonal antibodies against CGRP or the CGRP receptor have a longer duration of action and have been investigated for migraine prevention. Four are in development and three have completed phase II and one phase III trials; every reported study has been positive. Furthermore, no safety issues have arisen to date, including hepatic or cardiovascular effects, and initial tolerability appears to be excellent. Monoclonal antibodies antagonizing the CGRP pathway represent a novel approach to prevention: a mechanism-specific migraine-targeted therapy. While we must await the results of all the phase III trials, cautious excitement seems warranted as we enter a new era of better tolerated, well-understood, bespoke migraine treatment for this common and disabling neurological disorder.
Pillared Clays and Pillared Layered Solids (1999)

Abstract Pillaring is a commonly used procedure to transform a layered crystalline inorganic compound into a material with microporosity and mesoporosity. First, the terms "layered compound, pillaring, pillaring agent and interlayer region" are defined, and then the term pillared layered solid or pillared compound. In the second part, the standard characterization methods and procedures and a systematic classification scheme are proposed.
Studies in Fat Grafting (2014)

Fat grafting attenuates dermal collagen deposition and vessel depletion characteristic of radiation fibrosis. Although fat graft retention rates are significantly lower in irradiated than in nonirradiated tissue, the quality of retained fat between the groups is similar.
The Relationship Between Modifiable Health Risks and Health Care Expenditures (1998)

This investigation estimates the impact of ten modifiable health risk behaviors and measures and their impact on health care expenditures, controlling for other measured risk and demographic factors. Retrospective two-stage multivariate analyses, including logistic and linear regression models, were used to follow up 46,026 employees from six large health care purchasers for up to 3 years after they completed an initial health risk appraisal. These participants contributed 113,963 person-years of experience. Results show that employees at high risk for poor health outcomes had significantly higher expenditures than did subjects at lower risk in seven of ten risk categories: those who reported themselves as depressed (70% higher expenditures), at high stress (46%), with high blood glucose levels (35%), at extremely high or low body weight (21%), former (20%) and current (14%) tobacco users, with high blood pressure (12%), and with sedentary lifestyle (10%). These same risk factors were found to be associated with a higher likelihood of having extremely high (outlier) expenditures. Employees with multiple risk profiles for specific disease outcomes had higher expenditures than did those without these profiles for the following diseases: heart disease (228% higher expenditures), psychosocial problems (147%), and stroke (85%). Compared with prior studies, the results provide more precise estimates of the incremental medical expenditures associated with common modifiable risk factors after we controlled for multiple risk conditions and demographic confounders. The authors conclude that common modifiable health risks are associated with short-term increases in the likelihood of incurring health expenditures and in the magnitude of those expenditures.
Propagation and morphologic phenotypes of human umbilical cord artery endothelial cells. (1986)

Human umbilical cord artery endothelial cells can be propagated on fibronectin-coated dishes for approximately 50 cumulative population doublings in the presence of crude preparations of endothelial cell growth factor (ECGF) and serum. The cells were characterized by immunofluorescent staining and their ultrastructure. Different morphologic phenotypes could be demonstrated: closely attached cell monolayers, atypical cells, giant cells, tube-like structures. The formation of tube-like structures can be induced by proteolytic modification of fibronectin. Our data demonstrate that umbilical arteries may provide an excellent source for the routine serial cultivation of human arterial endothelial cells.
Strategies to protect crop plants against viruses: pathogen-derived resistance blossoms. (1993)

Since 1986, the ability to confer resistance against an otherwise devastating virus by introducing a single pathogen-derived or virus-targeted sequence into the DNA of a potential host plant has had a marked influence on much of the research effort, focus, and short-term objectives of plant virologists throughout the world. The vast literature on coat protein-mediated protection, for example, attests to our fascination for unraveling fundamental molecular mechanism(s), our (vain) search for a unifying hypothesis, our pragmatic interest in commercially exploitable opportunities for crop protection, and our ingenuity in manipulating transgene constructions to broaden their utility and reduce real or perceived environmental risk issues. Other single dominant, pathogen-derived plant resistance genes have recently been discovered from a wide variety of viruses and are operative in an ever-increasing range of plant species. Additional candidates seem limited only by the effort invested in experimentation and by our ingenuity and imagination. This review attempts to consider, in a critical way, the current state of the art, some exceptions, and some proposed rules. The final impression, from all the case evidence considered, is that normal virus replication requires a subtle blend of host- and virus-coded proteins, present in critical relative concentrations and at specific times and places. Any unregulated superimposition of interfering protein or nucleic acid species can, therefore, result in an apparently virus-resistant plant phenotype.
Randomized, double-blind, placebo-matched, multicenter trial of abacavir/lamivudine or tenofovir/emtricitabine with lopinavir/ritonavir for initial HIV treatment (2009)

Both ABC/3TC and TDF/FTC provided comparable antiviral efficacy, safety, and tolerability when each was combined with lopinavir/ritonavir in treatment-naive patients.
Plant genotyping II: SNP technology (2008)

Recent developments focus on high- throughput methods and generally target single nucleotide polymorphism (SNP) discovery and analysis. The topics covered include: SNP discovery in plants; SNPs and their use in maize; rare SNP discovery with endonucleases; sequence polymorphisms in the flanking regions of microsatellite markers; SNP discovery by ecotilling using capillary electrophoresis; genotyping by allele-specific PCR; the MassARRAY system for plant genomics; mutation screening; nanotechnology (the future of cost-effective plant genotyping); functionally associated molecular genetic markers for temperate pasture plant improvement; genotyping for rice eating qualities; towards universal loci for plant genotyping; DNA banks as a resource for SNP genotyping; DNA extraction from plant tissue; future prospects for plant genotyping.
Phase I dose escalation trial of docetaxel plus curcumin in patients with advanced and metastatic breast cancer (2010)

The recommended dose of curcumin is 6,000 mg/d for seven consecutive d every 3 w in combination with a standard dose of docetaxel. From the encouraging efficacy results, a comparative phase II trial of this regimen plus docetaxel versus docetaxel alone is ongoing in advanced and metastatic breast cancer patients.
Preclinical evaluation of injectable sirolimus formulated with polymeric nanoparticle for cancer therapy (2012)

Nanoparticles are useful delivery vehicles for promising drug candidates that face obstacles for clinical applicability. Sirolimus, an inhibitor of mammalian target of rapamycin has gained attention for targeted anticancer therapy, but its clinical application has been limited by its poor solubility. This study was designed to enhance the feasibility of sirolimus for human cancer treatment. Polymeric nanoparticle (PNP)-sirolimus was developed as an injectable formulation and has been characterized by transmission electron microscopy and dynamic light scattering. Pharmacokinetic analysis revealed that PNP-sirolimus has prolonged circulation in the blood. In addition, PNP-sirolimus preserved the in vitro killing effect of free sirolimus against cancer cells, and intravenous administration displayed its potent in vivo anticancer efficacy in xenograft tumor mice. In addition, PNP-sirolimus enhanced the radiotherapeutic efficacy of sirolimus both in vitro and in vivo. Clinical application of PNP-sirolimus is a promising strategy for human cancer treatment.
Hdmx Stabilizes Mdm2 and p53 (2000)

The Mdm2 protein is a key regulator of p53 activity and stability. Upon binding, Mdm2 inhibits the transcription regulatory activity of p53 and promotes its rapid degradation. In this study we investigated the effect of the human Mdm2 homologue Hdmx on p53 stability. We found that Hdmx does not target p53 for degradation, although, like Mdm2, it inhibits p53-mediated transcription activation. On the contrary, Hdmx was found to counteract the degradation of p53 by Mdm2, and to stabilize both p53 and Mdm2. The RING finger of Hdmx was found to be necessary and sufficient for this stabilization, and it probably involves hetero-oligomerization with the RING finger of Mdm2, which may lead to inhibition of Mdm2's ubiquitin ligase activity. However, Hdmx does not relieve the inhibition by Mdm2 of transcription activation by p53, probably due to the formation of a trimeric complex consisting of Hdmx, Mdm2, and p53. We propose a model in which Hdmx secures a pool of largely inactive p53, which, upon the induction of stress, can be quickly activated.
Structure and function of immunoglobulin domains. V. Binding, University of immunoglobulin G and fragments to placental membrane preparations. (1976)

Fc receptors have been shown to be present in human placental tissue with properties distinct from those on macrophages and lymphocytes. A single class of receptor was observed with an intrinsic affinity 4X 10(6) M-(1) for human IgG1. The order of affinity for IgG subclasses was IgG1 = IGG1 greater than IgG3 greater than IgG4. IgA and IgM were not bound. Fc from IgG1 bound with the same affinity as the whole molecule and to the same number of receptor sites, 2 X 10 (12)/mg placental protein. IgG1 was no longer boung after mild reduction and alkylation whereas the binding of Fc was unaffected by this treatment. Neithe C3 nor C3, the two domains which comprise the Fc region of IgG1, bound to the placental receptor. This implies that this Fc receptor is unlike those found on most cell surfaces and that plasental binding is an exception to the theory that each domain has evoked to perform independent functions.
Transplantation of undifferentiated murine embryonic stem cells in the heart: teratoma formation and immune response (2007)

Embryonic stem (ES) cells are promising for cardiac repair, but directing their differentiation toward cardiomyocytes remains challenging. We investigated whether the heart guides ES cells toward cardiomyocytes in vivo and whether allogeneic ES cells were immunologically tolerated. Undifferentiated mouse ES cells consistently formed cardiac teratomas in nude or immunocompetent syngeneic mice. Cardiac teratomas contained no more cardiomyocytes than hind-limb teratomas, suggesting lack of guided differentiation. ES cells also formed teratomas in infarcted hearts, indicating injury-related signals did not direct cardiac differentiation. Allogeneic ES cells also caused cardiac teratomas, but these were immunologically rejected after several weeks, in association with increased inflammation and up-regulation of class I and II histocompatibility antigens. Fusion between ES cells and cardiomyocytes occurred in vivo, but was rare. Infarct autofluorescence was identified as an artifact that might be mistaken for enhanced GFP expression and true regeneration. Hence, undifferentiated ES cells were not guided toward a cardiomyocyte fate in either normal or infarcted hearts, and there was no evidence for allogeneic immune tolerance of ES cell derivatives. Successful cardiac repair strategies involving ES cells will need to control cardiac differentiation, avoid introducing undifferentiated cells, and will likely require immune modulation to avoid rejection.
Found in Translation (2009)

This book seeks to explore how film adaptations of
comic art are constructed and received. Through an
analysis comparing different types of comic-to-film
adaptations selected from a nearly comprehensive
list, a set of adaptive operations was discovered
based upon the narrative and stylistic relationships
between film adaptations and comic art source
materials. Depending upon which operations are used,
adaptations may be classified as predominately
structural or thematic. At one extreme there are
structural adaptations that feature an almost
precise correspondence of narrative events between
comic source and film adaptation. At the other
extreme, thematic adaptations have no relationship
of narrative structure to the comic source being
adapted, but retain key conflicts and characters.
Having established this opposition, a second study
was performed to determine the differential effect
of reading and viewing a structural versus a
thematic adaptation on the experience of
telepresence – “the perceptual illusion of
nonmediation” (Lombard & Ditton, 1997). Implications
for telepresence theory and cultural transmission of
experience are discussed.
Induction Therapy for Pediatric and Adult Heart Transplantation: Comparison Between OKT3 and Daclizumab (2005)

Daclizumab induction therapy is as efficacious as OKT3 in the prevention of early acute rejection after heart transplantation among pediatric and adult subjects. Complications related to the induction agent are significantly lower in the humanized product.
A SURVEY OF PUBLIC- KEY INFRASTRUCTURES (1997)

Public-key cryptography is fast becoming the foundation for online commerce and other applications that require security and authentication in an open network. The widespread use of public-key cryptography requires a public-key infrastructure to publish and manage public-key values. Without a functioning infrastructure, public-key cryptography is only marginally more useful than traditional, secret -key cryptography. This thesis presents a set of characteristics that are common to all public-key infrastructures. These criteria are intended to encapsulate the fundamental issues that arise when dealing with such systems. They can be used both as a &amp;quot;shopping list&amp;quot; for those who need to choose an infrastructure for a particular application, and as a guide for infrastructure developers, that they may be more aware of any compromises or tradeoffs they might make in their work. The characteristics are used to present a survey of current and some proposed infrastructure systems. The criteria...
Methionine metabolism in mammals. Distribution of homocysteine between competing pathways. (1984)

Using an in vitro system which contained enzymes, substrates, and other reactants at concentrations which approximated the in vivo conditions in rat liver, we measured the simultaneous product formation by three enzymes which utilize homocysteine. In the control system, 5-methyltetrahydrofolate homocysteine methyltransferase, betaine homocysteine methyltransferase, and cystathionine beta-synthase accounted for 27, 27, and 46%, respectively, of the homocysteine consumed. Subsequent studies demonstrated that the adaptation from a high protein diet to a low protein diet is achieved by a significant increase in betaine homocysteine methyltransferase, and 83% reduction in cystathionine synthase, and a total decrease of 55% in the consumption of homocysteine. S-Adenosylmethionine, by activating cystathionine synthase, contributes significantly to the regulation of the pathway.
The human and rodent intestinal fatty acid binding protein genes. A comparative analysis of their structure, expression, and linkage relationships. (1987)

Intestinal fatty acid binding protein (I-FABP) is believed to participate in the uptake, intracellular metabolism, and/or transport of long chain fatty acids within enterocytes. The 15.1-kDA rodent proteins is a member of a family of low Mr cytoplasmic proteins that have evolved to bind different ligands. We have now determined the nucleotide sequence of the gene encoding human I-FABP and defined the primary structure of its protein product. The human I-FABP gene spans 3382 nucleotides and contains 4 exons (103 or 128, 173, 108, and 312 base pairs). interrupted by 3 introns (1194, 1023, and 444 base pairs). The 132-residue rat and human I-FABPs have 82% amino acid sequence identity. Blot hybridization studies of RNAs prepared from a variety of adult rhesus monkey tissues as well as human intestine and liver indicate that I-FABP mRNA is confined to the intestine. I-FABP mRNA was not detectable in a number of cultured human enterocyte-like cell lines, suggesting it may be a sensitive marker for differentiated, villus-associated, small intestinal lining cells. Given the similar patterns of tissue-specific expression exhibited by the rat and human genes, we compared their 5' nontranscribed regions. Optimal alignments of the two sequences disclosed 64% identity among the 260 nucleotides immediately 5' to the start site of transcription. Matrix plots revealed a 14-nucleotide long repeated sequence (5'-TGAACTTTGAACTT-3') in the 5' nontranscribed region of both genes as well as in a comparable region of another family member that is expressed in enterocytes, cellular retinol binding protein II. The linkage relationships between I-FABP and the homologous liver FABP (L-FABP) gene were defined in mice and humans. The mouse genes were mapped using restriction fragment length polymorphisms and recombinant inbred strains. The I-FABP gene is located on mouse chromosome 3 between the amylase 1,2 (Amy 1,2) and alcohol dehydrogenase 3 (Adh-3) loci while the L-FABP gene is on mouse chromosome 6 within 3 centimorgans of the lymphocyte antigen-2 (Ly-2) locus. Mouse L-FABP may be identical to the major liver protein-1 (Lvp-1) which is encoded by a gene situated within a centimorgan of Ly-2. Human gene mapping studies were carried out using a panel of mouse-human somatic cell hybrid clones as well as in situ hybridization to metaphase chromosomes.(ABSTRACT TRUNCATED AT 400 WORDS)
