To describe pesticide concentrations in distinct environmental matrices at two time points (low and high seasons in local agricultural production) and to estimate the association between the presence of pesticide residues in matrices and the use of pesticides in the home with the sociodemographic variables of schoolchildren in the Province of Talca, Chile. A cross-sectional study was conducted in 190 schoolchildren. Families were surveyed about their children's vegetable consumption in school and at home, the use of pesticides in the home, and other sociodemographic variables. Additionally, we measured pesticide residues in vegetables and water consumed by the schoolchildren and in the soil of 14 schools. At both time points, the vegetable matrix had the highest pesticide concentration, both in urban and rural schoolchildren. The most common pesticide residues in vegetables were chlorpyrifos, diphenylamine, pyrimethanil, and thiabendazole. In the home, pyrethroid and organophosphate pesticides were mainly used in summer. Dangerous pesticide residues such as azinphos methyl and dimethoate were found in vegetables consumed by the children in schools and households, and organochlorines were found in the soil in some schools. Pesticide exposure should be limited and the health effects related to pesticide exposure should be assessed in the school population. Copyright © 2013 SESPAS. Published by Elsevier Espana.

Prof. Jakob Narkiewicz-Jodko (1947-1905) major discoveries are: Electrography - the method of the visualization of electric discharge from the bodies due to the application of high strength and high frequency electric fields, and the first observation of the propagation of the electromagnetic waives for information transfer over the distances. They were made in his laboratory located at his manor home Nadniemen. We describe these experiments and the Lab equipment used for the discoveries. Unfortunately the Nadniemen manor designed and built in Neogothic style was destroyed at the WWII. Our goal is to restore the Lab of Prof. Jakob Narkiewicz-Jodko as a museum. We also introduce our hypothesis regarding architectural design of the manor home Nadniemen.

Dokic, D

2013-01-01

University Pulmology and Allergy Clinic was founded in 1975 when the Depertment of Internal Medicine, directed by Prof. Dr. Dimitar Arsov, later member of the Macedonian Academy of Sciencies and Arts, was divided into eight separate and independent clinics. The first head of the Pulmonology and Allergy Clinic was Prof. Dr. Ljubomir Kotevski. He had a very difficult goal: to establish and further develop the newly formed clinic. The Clinic flourished and became one of the leading Clinics in the Clinical Centre during the directorship of Prof. dr. Dejan Dokic.. He completely rebuilt and refurbished the Clinic, which became a modern Clinic providing excellent working conditions for the employees and, most importantly, provided a first class service to the patients. During his mandate he obtained a grant from the Japanese Government worth $1,000,000 which was used to obtain a new, modern and sophisticated medical equipment. Since the establishment of the clinic, many national and international scientific projects were carried out and many scientific papers were published as well as many monographs, and chapters in scientific books. As a result of continuous education, of the total number of 24 doctors there are 16 subspecialists in respiratory medicine and 4 specialists in internal medicine. There are 9 professors in internal medicine at the University of Pulmonology and Allergy Clinic lecturing at the Medical Faculty in Skopje. The University Pulmonology and Allergy Clinic has an international reputation due to many contacts with famous European Institutions. All these international interrelations have resulted in honouring 3 professors: Prof. Dr. Gert Kunkel from Berlin, Germany, Prof. Dr. Robert Loddenkemper from Berlin, Germany and Prof. Dr. Peter Howard from Southampton, UK.

Dr. Karol de Beaurain - a psychiatrist's profile. Part 2.

PubMed

Rutkowski, Krzysztof; Dembińska, Edyta

2017-06-18

The paper sets out to recall the profile of Karol de Beaurain, a psychiatrist, who was one of first Poles to use the psychoanalytic method in treatment. So far, he has been mostly known as the one who was Witkacy's psychoanalyst. Stanisław Ignacy Witkiewicz and Eugenia Dunin-Borkowska are the first patients who are known by their names and who received psychoanalytic treatment in the history of the Polish medicine. Stanisław Ignacy Witkiewicz's letters and drawings originating from the psychoanalysis period served as a source of information about Witkacy's psychoanalysis. The paper illustrates dr Beaurain's fate during World War I when he was first a military doctor in Skoczów and then an assistant in prof. Piltz's Neurological-Psychiatric Clinic in Kraków where he actively participated in the creation of a multidimensional programme of war neurosis treatment. After the war finished, initially Beaurain stayed at his assistant post at the Psychiatric Clinic in Kraków but then in 1921 he relocated to the National Psychiatric Hospital in Dziekanka near Poznań. With his professional expertise he contributed to the strengthening of the Great Poland region psychiatry that had experienced qualified personnel shortages after the German qualified staff left. The growing numbers of patients and the overload of professional duties were probably the factors that led to dr. Beaurain's premature death while he was holding the position of the head physician at the National Psychiatric Hospital in Owińska in February 1927.

Prof. Il-Hoi Kim was born during the Korean War on 28 February 1952 in Buan, North Jeolla Province (South Korea), near the coast of the Yellow Sea whose tidal flats would become one of his favourite sampling grounds during his scientific career. From an early age he developed an intense interest in natural history in general and marine biology in particular. He obtained his B.Sc. in 1974 at the Department of Biology Education, Gongju National College of Education. Between 1974 and 1976 he was conscripted into the South Korean military during which he progressed to the rank of lieutenant of artillery in the Reserve Officers' Training Corps (ROTC). After his graduation in 1980 at the Department of Zoology, Seoul National University, Il-Hoi Kim moved to the Department of Biology, Gangneung-Wonju National University on the East Sea coast where he was first appointed lecturer (1981) before taking up the position of assistant professor (1983), associate professor (1987) and full professor (1993). In 1985 he had previously completed his Ph.D. dissertation on Korean barnacles at Seoul National University under the supervision of the late Prof. Hoon Soo Kim, a pioneer in marine invertebrate taxonomy and renowned as the father of carcinology in Korea.

[Dr Stockmann and Dr Snow--two heroes of public health].

PubMed

Nylenna, Magne

2003-12-23

Dr Thomas Stockmann, the main character of An enemy of the people by Henrik Ibsen (1828-1906), has been described as a hero of public health. In spite of his idealism and high principles, he was, however, not able to do anything about the contaminated water supply of the baths in the town where he lived. Important differences may be noticed if we compare the fictional Dr Stockmann with Dr John Snow (1813-58), a real hero of public health famous for his handling of a cholera epidemic in London in 1854. While Dr Snow carried out extensive investigations of the relation between water supply and illness and still was humble when presenting his findings, the fictional Dr Stockmann took only one sample of water for examination and was bombastic in his conclusion. And while Dr Snow had a simple suggestion for solving the problem, Dr Stockmann seemed more eager to dramatize the situation. Scientific documentation and a practical attitude to problem solving continue to be important in order to achieve results in the field of public health.

The use of next generation sequencing has expanded our view on whole mammalian methylome patterns. In particular, it provides a genome-wide insight of local DNA methylation diversity at single nucleotide level and enables the examination of single chromosome sequence sections at a sufficient statistical power. We describe a bisulfite-based sequence profiling pipeline, Bi-PROF, which is based on the 454 GS-FLX Titanium technology that allows to obtain up to one million sequence stretches at single base pair resolution without laborious subcloning. To illustrate the performance of the experimental workflow connected to a bioinformatics program pipeline (BiQ Analyzer HT) we present a test analysis set of 68 different epigenetic marker regions (amplicons) in five individual patient-derived xenograft tissue samples of colorectal cancer and one healthy colon epithelium sample as a control. After the 454 GS-FLX Titanium run, sequence read processing and sample decoding, the obtained alignments are quality controlled and statistically evaluated. Comprehensive methylation pattern interpretation (profiling) assessed by analyzing 102-104 sequence reads per amplicon allows an unprecedented deep view on pattern formation and methylation marker heterogeneity in tissues concerned by complex diseases like cancer.

The 60th anniversary of Israel coincides with the advent of the first hemodialysis in the Middle East. It was performed by Dr. Kurt Steinitz--a Jewish immigrant from Breslau, then in Germany. After spending 9 years at the Istanbul Faculty of Medicine as a clinical biochemist, Steinitz became the director of the chemical laboratory of the Rothschild Hospital in Haifa in 1945. During the spring of 1948, he completed the construction of a hemodialysis machine according to articles published by Kolff (The Netherlands) and mainly by Alwall (Sweden). Three anuric patients underwent hemodialysis. Only the last patient survived. She was a young woman who became anuric after an operation for an extrauterine pregnancy and an incompatible blood transfusion. During the 28th and the 30th September 1948, she had three successful hemodialysis sessions and improved promptly. She lived another fifteen fruitful years. Later, Dr Steinitz' interest shifted to other medical fields, thus leaving the stage of hemodialysis to Prof. David Ullman from the Hadassah Hospital in Jerusalem. Ullman established the first nephrology unit with a regular dialysis service, becoming the pioneer of modern nephrology in Israel.

In a seminal paper of 1967, Professor Chen Ning Yang found the full solution of the one-dimensional Fermi gas with a repulsive delta function interaction by using the Bethe ansatz and group theory. This work with a brilliant discovery of the Yang-Baxter equation has been inspiring new developments in mathematical physics, statistical physics, and many-body physics. Based on experimental developments in simulating many-body physics of one-dimensional systems of ultracold atoms, during a period from 2009 to 2011, Prof. Yang published seven papers on the exact properties of the ground state of bosonic and fermionic atoms with the repulsive delta function interaction and a confined potential to one dimension. Here I would like to share my experience in doing research work fortunately under the direct supervision of Prof. Yang in that period.

A >2-MJ, 1014-W laser system for DT fusion—NIF: a note in celebration of the 75th birthday of Prof. Theodore Haensch

NASA Astrophysics Data System (ADS)

Holzrichter, John F.; Manes, Kenneth R.

2017-01-01

In 1970, Dr. Theodore Haensch joined A.L. Schawlow's group in the physics department at Stanford, as a NATO postdoctoral researcher. Within a short time, he and his colleagues had invented a new, high-resolution, tunable laser system using expanded reflection gratings and an N2 laser for pumping the fluorescing dyes. This work resulted in a high-brightness, high-repetition-rate, narrow-band laser probe for conducting optical spectroscopy at extreme levels of precision. Dr. Haensch, and his many colleagues, particularly Prof. Arthur Schawlow and their students at Stanford, then proceeded to revolutionize optical spectroscopy and to train several generations of exceptional young scientists. At the same time, the Siegman, Harris, and Byer laboratories also at Stanford were making major contributions to the laser and quantum electronics fields. Several students from both groups joined the Livermore Laboratory. That early work, and that of others, encouraged teams at the Lawrence Livermore National Laboratory to design and build a series of increasing complicated, high-power multi-beam laser systems to investigate the potential of laser fusion. The National Ignition Facility, recently completed, is enabling investigations of matter at very high temperatures, T > 1 million K and densities 100-1000× normal. In addition, researchers are creating 1015 DT fusion neutrons per fusion experiment and generating new knowledge about unusual and important conditions of matter.

It was great to be associated with Prof. Dr. Karl Rawer. He devoted his life to make use of the wonderful laboratory of Nature, the Ionosphere. Through acquisition of the experimental data from AEROS satellites and embedding it with data from ground stations, it was possible to achieve a better empirical model, the International Reference Ionosphere. Prof. Dr. Karl Rawer has been as dynamic as the Ionosphere. His vision about the ionospheric data is exceptional and has helped the scientific and engineering community to make use of his vision in advancing the dimensions of empirical modelling. As a human being, Prof. Dr. Karl Rawer has all the traits of an angel from Heaven. In short he developed a large team of researchers forming a blooming tree from the parent node. Ionosphere still plays an important role in over the horizon HF Radar and GPs satellite data reduction.

The second Gaia data release, Gaia DR2, encompasses astrometry, photometry, radial velocities, astrophysical parameters (stellar effective temperature, extinction, reddening, radius, and luminosity), and variability information plus astrometry and photometry for a sample of pre-selected bodies in the solar system. The data collected during the first 22 months of the nominal, five-year mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC), resulting into this second data release. A summary of the release properties is provided in Gaia Collaboration et al. (2018b). The overall scientific validation of the data is described in Arenou et al. (2018). Background information on the mission and the spacecraft can be found in Gaia Collaboration et al. (2016), with a more detailed presentation of the Radial Velocity Spectrometer (RVS) in Cropper et al. (2018). In addition, Gaia DR2 is accompanied by various, dedicated papers that describe the processing and validation of the various data products. Four more Gaia Collaboration papers present a glimpse of the scientific richness of the data. In addition to this set of refereed publications, this documentation provides a detailed, complete overview of the processing and validation of the Gaia DR2 data. Gaia data, from both Gaia DR1 and Gaia DR2, can be retrieved from the Gaia archive, which is accessible from https://archives.esac.esa.int/gaia. The archive also provides various tutorials on data access and data queries plus an integrated data model (i.e., description of the various fields in the data tables). In addition, Luri et al. (2018) provide concrete advice on how to deal with Gaia astrometry, with recommendations on how best to estimate distances from parallaxes. The Gaia archive features an enhanced visualisation service which can be used for quick initial explorations of the entire Gaia DR2 data set. Pre-computed cross matches between Gaia DR2 and a selected set of large surveys are

2006-05-01

This special issue of the Journal of Physics: Conference Series contains the proceedings of the joint Seventh International Conference on New Phenomena in Mesoscopic Structures and Fifth International Conference on Surfaces and Interfaces of Mesoscopic Devices, which was held from November 27th - December 2nd, 2005, at the Ritz Carlton Kapalua, Maui, Hawaii. The string of these conferences dates back to the first one in 1989. Of special importance is that this year's conference was dedicated to Professor Gottfried Landwehr, in recognition of his many outstanding contributions to semiconductor physics. A personal tribute to Prof Landwehr by Dr K von Klitzing leads off this issue. The scope of NPMS-7/SIMD-5 spans nano-fabrication through complex phase coherent mesoscopic systems including nano-transistors and nano-scale characterization. Topics of interest include: •Nanoscale fabrication: high-resolution electron lithography, FIB nano-patterning, scanning- force-microscopy (SFM) lithography, SFM-stimulated growth, novel patterning, nano-imprint lithography, special etching, and self-assembled monolayers •Nanocharacterization: SFM characterization, ballistic-electron emission microscopy (BEEM), optical studies of nanostructures, tunneling, properties of discrete impurities, phase coherence, noise, THz studies, and electro-luminescence in small structures •Nanodevices: ultra-scaled FETs, quantum single-electron transistors (SETS), resonant tunneling diodes, ferromagnetic and spin devices, superlattice arrays, IR detectors with quantum dots and wires, quantum point contacts, non-equilibrium transport, simulation, ballistic transport, molecular electronic devices, carbon nanotubes, spin selection devices, spin-coupled quantum dots, and nanomagnetics •Quantum-coherent transport: the quantum Hall effect, ballistic quantum systems, quantum-computing implementations and theory, and magnetic spin systems •Mesoscopic structures: quantum wires and dots, quantum chaos

During the years when Dr. M. Matsuoka was professor of the Department of Orthopaedic Surgery, Kyoto Medical School, Kyoto Imperial University (June, 1907-January, 1914), seven doctors worked as his faculty members and founded the base of the current development and reputation of the Department. After resignation from their academic positions, they served in orthopaedic practice in several areas in Japan where orthopaedic surgery was not well recognized. In addition, Prof. Matsuoka trained three doctors from the Aichi Prefectural Medical College (School of Medicine, Nagoya University) in the orthopaedic practice, including x-ray technique and they contributed to the development of orthopaedic surgery in the areas of Nagoya city and Tokai. Backgrounds and achievements of these ten doctors are described.

Dual Agonist Surrobody Simultaneously Activates Death Receptors DR4 and DR5 to Induce Cancer Cell Death.

Death receptors of the TNF family are found on the surface of most cancer cells and their activation typically kills cancer cells through the stimulation of the extrinsic apoptotic pathway. The endogenous ligand for death receptors 4 and 5 (DR4 and DR5) is TNF-related apoptosis-inducing ligand, TRAIL (Apo2L). As most untransformed cells are not susceptible to TRAIL-induced apoptosis, death receptor activators have emerged as promising cancer therapeutic agents. One strategy to stimulate death receptors in cancer patients is to use soluble human recombinant TRAIL protein, but this agent has limitations of a short half-life and decoy receptor sequestration. Another strategy that attempted to evade decoy receptor sequestration and to provide improved pharmacokinetic properties was to generate DR4 or DR5 agonist antibodies. The resulting monoclonal agonist antibodies overcame the limitations of short half-life and avoided decoy receptor sequestration, but are limited by activating only one of the two death receptors. Here, we describe a DR4 and DR5 dual agonist produced using Surrobody technology that activates both DR4 and DR5 to induce apoptotic death of cancer cells in vitro and in vivo and also avoids decoy receptor sequestration. This fully human anti-DR4/DR5 Surrobody displays superior potency to DR4- and DR5-specific antibodies, even when combined with TRAIL-sensitizing proapoptotic agents. Moreover, cancer cells were less likely to acquire resistance to Surrobody than either anti-DR4 or anti-DR5 monospecific antibodies. Taken together, Surrobody shows promising preclinical proapoptotic activity against cancer cells, meriting further exploration of its potential as a novel cancer therapeutic agent. ©2015 American Association for Cancer Research.

The role of the South African Veterinary Council, with special reference to the period 1982-2011.

Ardington, Peter C; Bigalke, Rudolph D

2014-11-14

The current South African Veterinary Council (SAVC) has a long and laborious history associated with the legislation responsible for its establishment. The forerunner of the SAVC, the South African Veterinary Board, was established in terms of the Veterinary Act 1933 (Act No. 16 of 1933), which was launched through Parliament as a private motion by Dr Hjalmar Reitz M.P. After several amendments, the Act was replaced with the Veterinary and Para-veterinary Professions Act 1982 (Act No. 19 of 1982), superseding the existing Board with the SAVC. One of the reasons for replacing this Act was to comply with Government policy for professional statutory bodies to become self-funding, with fees paid by registered professionals, and to constitute councils that were more representative of the profession. Apart from providing some background information, this article was virtually entirely confined to some historic aspects of the SAVC, using, as its basis, the main developments that occurred during the terms of office of its various presidents, serving from 1982 to 2011. The presidents concerned are: Prof. B.C. Jansen (28 March 1983 - 28 March 1986), Dr G.E. Frost (14 April 1986 - 31 March 1992), Prof. R.I. Coubrough (07 April 1992 - 21 March 1994), Dr P.C. Ardington (21 March 1994 - 31 March 1998), Prof H.M. Terblanche (31 March 1998 - 31 March 2004), Prof. S.S. van den Berg (01 April 2004 - 30 July 2007) and Dr R. Moerane (06 August 2007 - 31 July 2013).

We synthesized pairs of four different oligonucleotides, F22, F29, F42, and F158, to analyse the HLA-DR2 (DRw15) and -DR4 haplotypes in the Japanese population. After enzymatically amplifying the HLA-DRB1 gene, we hybridized the oligonucleotide probes with DNA extracted from 42 donors. Hybridization was completed between F22 and the DNA of haplotype DR2 (DRw15)-Dw2, between F29 and the DNA of DR2 (DRw15)-Dw12, between F42 and the DNA of DR4-D"KT2", and between F158 and the DNA of DR4-Dw15. In keeping with the nucleotide sequences of the probes, F29 hybridized also with DNA from the DR9-Dw23 haplotype and F158 with that from some of the DRw8 haplotypes (DRw8-Dw8.3) in the Japanese population. Results of this study demonstrate that the four oligonucleotides make useful probes for detecting the haplotypes above.

Med., 2018, 244 (1), 75-81. doi: 10.1620/tjem.244.75.] The above Review article was published online on January 27, 2018. Soon after its publication (on February 1, 2018), Dr. Nian Fu and Prof. Linxi Chen informed the Editor-in-Chief, The Tohoku Journal of Experimental Medicine (TJEM), about serious violation of publication ethics. Indeed, Dr. Nian Fu and Prof. Linxi Chen were astonished to find their names as coauthors of this Review article, because they were not involved in the submission process of this Review article and they do not know any of other coauthors. In addition, the Review article is similar to their unpublished manuscript. After a thorough investigation in accordance with the recommendations of the Committee on Publication Ethics (COPE), the Editor-in-Chief of TJEM decided to retract this Review article. The reasons for Retraction are summarized below: forged authors and an unexpected case of plagiarism. Forged authors: Dr. Nian Fu and Prof. Linxi Chen were added as co-authors of the Review article without their knowledge. In fact, the signature provided by Prof. Linxi Chen is apparently different from the signature of a coauthor, named Linxi Chen, on the AUTHORS’ RESPONSIBILITY FORM, provided by the corresponding author of the Review article. More critically, the signature provided by Dr. Nian Fu is completely different from the signature of Nian Fu, because the Chinese characters are different between the two signatures. In addition, the replies from three authors (Ming Zhou, Hongwen Ji and Yong Xia) clearly indicate that they misunderstand the identity of Dr. Nina Fu. We also attempted to contact two authors, named Nian Fu and Linxi Chen, via e-mail. As expected, the forged authors did not respond to our inquiries, despite that their e-mail addresses appear to be active. An unexpected case of plagiarism: This Review article is similar to the

NASA Astrophysics Data System (ADS)

Gobron, Nadine; Ollier, Gilles

The Group on Earth Observations is coordinating efforts to build a Global Earth Observation System of Systems, or GEOSS. GEO is a voluntary partnership of governments and inter-national organizations. It provides a framework within which these partners can develop new projects and coordinate their strategies and investments. The Science and Technology Commit-tee of GEO is working to strengthen this role by encouraging the wider scientific and technology community to participate as contributors to and benefactors of a sustained GEOSS. The proposed round table aims at discussing how are scientists and GEO currently working together, using specific examples and how do space agencies or data providers contribute to GEO? Round table participants are welcome to present their own vision on future actions to improve, if necessary, the relations between contributors and GEO. Meeting participants will also be offered the opportunity to intervene and ask questions to the panel. Moderators: • Dr. Nadine Gobron -EC-JRC -Chair of Commission A • Gilles Ollier -DG Research Participants: • Prof. José Achache -Director of GEO • Prof. Maurice Bonnet -President of COSPAR • Dr. Tamatsu Igarashi -JAXA EORC Manager • Dr. Stuart Minchin (CSIRO and member of GEO STC) TBC • Prof. Berrien Moore -Executive Director of Climate Central • Dr. Diane E.

Yet his work attracted little serious attention during his lifetime. However, when the United States began to prepare for the conquest of space in the 1950's, American rocket scientists began to recognize the debt owed to the New England professor. They discovered that it was virtually impossible to construct a rocket or launch a satellite without acknowledging the work of Dr. Goddard.

Patients with high-risk HLA-DR-DQ genotypes for type 1 diabetes (T1D) were compared to HLA-matched controls to evaluate T1D risk for other HLA loci, including HLA-A, -B, -Cw, and DPB1. Patients (n=133) with high-risk genotypes (DR3/DR3, DR3/DR4, DR4/DR4) were selected from the Lazio (Rome) region of Italy. Screening of more than 9000 subjects from the Lazio region and northern Italy yielded 162 controls with high- T1D-risk haplotypes. Although the overall distributions were not significantly different, allele frequency differences were discovered between the controls from Lazio and those from Northern Italy for some alleles previously shown to affect T1D risk, such as A*3002, DPB1*0301, and DPB1*0402. Therefore, Lazio patient data were compared both to the Lazio subset of controls (n=53) and to the entire group of controls for association analyses. Significant allele frequency differences between patients and DR-DQ-matched controls were found for specific alleles at all loci. Data for the DR3/DR3 subset of patients and controls showed an increase of Cw*0702 in patients. Reduced patient, compared to control, frequencies were seen for several alleles, including A*0101, B*0801, and Cw*0701, all found on the highly-conserved, extended DR3 haplotype known as 8.1 in DR3/DR3, but not DR3/DR4, subgroup. DPB1*0101, often found on 8.1 haplotypes, was also less frequent in DR3/DR3 patients than controls. Analysis of family-based data from the HBDI repository was consistent with the observed results from the Italian subjects, suggesting the presence of a T1D-protective locus at or near A*0101 and a second T1D-protective locus at or near DPB1*0101. These data suggest that T1D risk conferred by the 8.1 haplotype is genotype dependent. PMID:18486765

New observations of DR 15 and 20 are reported as part of a study of compact H II regions in the Cyg X region. The radio and FIR data for these objects, when combined with (C-12)O maps, IRAS imagery, and optical photographs, provide new insights into the structure of this complex region and the nature of the star-formation process there. The observations show that DR 15 may consist of one or two B0 ZAMS stars whose H I regions have formed a low-density cavity within a molecular cloud. DR 20 appears to be a young OB cluster. The cluster is dominated by an O5.5 ZAMS star and also contains an approximately 3500-yr-old B0 star appearing as a compact H II region, along with weak FIR sources that may be B0-star candidates.

Dr Pugh: a poisoner?

On 16 February 1845 the Reverend W. H. Browne, rector of St John's Church in Launceston, Van Diemen's Land, wrote in his journal, "My dear Wife died very suddenly almost immediately after and in consequence of taking a preparation of Hyd. Cyan. Acid prepared & supplied by Dr Pugh". This journal entry raises a number of questions. Was Dr Pugh treating a condition which he thought merited that treatment or was it a ghastly mistake? Was Caroline Browne suffering from pulmonary tuberculosis? Was hydrocyanic acid an accepted treatment at that time? Did Mrs Browne take the wrong dose? Was an incorrect concentration of the drug prepared by Dr Pugh? Did he use the wrong pharmacopoeia in preparing the hydrocyanic acid? Why was there no inquest? Only some of these questions can be answered.

Pathogenesis of Human Diffusely Adhering Escherichia coli Expressing Afa/Dr Adhesins (Afa/Dr DAEC): Current Insights and Future Challenges

PubMed Central

2014-01-01

SUMMARY The pathogenicity and clinical pertinence of diffusely adhering Escherichia coli expressing the Afa/Dr adhesins (Afa/Dr DAEC) in urinary tract infections (UTIs) and pregnancy complications are well established. In contrast, the implication of intestinal Afa/Dr DAEC in diarrhea is still under debate. These strains are age dependently involved in diarrhea in children, are apparently not involved in diarrhea in adults, and can also be asymptomatic intestinal microbiota strains in children and adult. This comprehensive review analyzes the epidemiology and diagnosis and highlights recent progress which has improved the understanding of Afa/Dr DAEC pathogenesis. Here, I summarize the roles of Afa/Dr DAEC virulence factors, including Afa/Dr adhesins, flagella, Sat toxin, and pks island products, in the development of specific mechanisms of pathogenicity. In intestinal epithelial polarized cells, the Afa/Dr adhesins trigger cell membrane receptor clustering and activation of the linked cell signaling pathways, promote structural and functional cell lesions and injuries in intestinal barrier, induce proinflammatory responses, create angiogenesis, instigate epithelial-mesenchymal transition-like events, and lead to pks-dependent DNA damage. UTI-associated Afa/Dr DAEC strains, following adhesin-membrane receptor cell interactions and activation of associated lipid raft-dependent cell signaling pathways, internalize in a microtubule-dependent manner within urinary tract epithelial cells, develop a particular intracellular lifestyle, and trigger a toxin-dependent cell detachment. In response to Afa/Dr DAEC infection, the host epithelial cells generate antibacterial defense responses. Finally, I discuss a hypothetical role of intestinal Afa/Dr DAEC strains that can act as “silent pathogens” with the capacity to emerge as “pathobionts” for the development of inflammatory bowel disease and intestinal carcinogenesis.

Cancer therapies are limited by the development of drug resistance, and mutations in drug targets is one of the main reasons for developing acquired resistance. The adequate knowledge of these mutations in drug targets would help to design effective personalized therapies. Keeping this in mind, we have developed a database "CancerDR", which provides information of 148 anti-cancer drugs, and their pharmacological profiling across 952 cancer cell lines. CancerDR provides comprehensive information about each drug target that includes; (i) sequence of natural variants, (ii) mutations, (iii) tertiary structure, and (iv) alignment profile of mutants/variants. A number of web-based tools have been integrated in CancerDR. This database will be very useful for identification of genetic alterations in genes encoding drug targets, and in turn the residues responsible for drug resistance. CancerDR allows user to identify promiscuous drug molecules that can kill wide range of cancer cells. CancerDR is freely accessible at http://crdd.osdd.net/raghava/cancerdr/

He was the first Center Director and served as the Director from July 1960 through February 1970. Following World War II, Dr. von Braun and his German colleagues arrived in the United States under the Project Paperclip (American acquisition of German rocket experts) to continue their rocket development work. In 1950, von Braun and his German Rocket Team (also called the Peenemuende Team) were transferred from Ft. Bliss, Texas to Huntsville, Alabama to work for the Army's rocket program at Redstone Arsenal and later, NASA's Marshall Space Flight Center (MSFC). Under Dr. von Braun's leadership, MSFC developed the Saturn V launch vehicle, which placed the first men, two American astronauts, on the Moon. Wernher von Braun's life was dedicated to expanding man's knowledge through the exploration of space.

Dysregulated cellular apoptosis and resistance to cell death are hallmarks of neoplastic initiation and disease progression. Therefore, the development of agents that overcome apoptosis dysregulation in tumor cells is an attractive therapeutic approach. Activation of the extrinsic apoptotic pathway is strongly dependent on death receptor (DR) hyperclustering on the cell surface. However, strategies to activate DR5 or DR4 through agonistic antibodies have had only limited clinical success. To pursue an alternative approach for tumor-targeted induction of apoptosis, we engineered a bispecific antibody (BsAb), which simultaneously targets fibroblast-activation protein (FAP) on cancer-associated fibroblasts in tumor stroma and DR5 on tumor cells. We hypothesized that bivalent binding to both FAP and DR5 leads to avidity-driven hyperclustering of DR5 and subsequently strong induction of apoptosis in tumor cells but not in normal cells. Here, we show that RG7386, an optimized FAP-DR5 BsAb, triggers potent tumor cell apoptosis in vitro and in vivo in preclinical tumor models with FAP-positive stroma. RG7386 antitumor efficacy was strictly FAP dependent, was independent of FcR cross-linking, and was superior to conventional DR5 antibodies. In combination with irinotecan or doxorubicin, FAP-DR5 treatment resulted in substantial tumor regression in patient-derived xenograft models. FAP-DR5 also demonstrated single-agent activity against FAP-expressing malignant cells, due to cross-binding of FAP and DR5 across tumor cells. Taken together, these data demonstrate that RG7386, a novel and potent antitumor agent in both mono- and combination therapies, overcomes limitations of previous DR5 antibodies and represents a promising approach to conquer tumor-associated resistance to apoptosis.

This paper describes automated demand response (Auto-DR) activities, an innovative effort in California to ensure that DR programs produce effective and sustainable impacts. Through the application of automation and communication technologies coupled with well-designed incentives and DR programs such as Critical Peak Pricing (CPP) and Demand Bidding (DBP), Auto-DR is opening up the opportunity for many different types of buildings to effectively participate in DR programs. We present the results of Auto-DR implementation efforts by the three California investor-owned utilities for the Summer of 2007. The presentation emphasizes Pacific Gas and Electric Company's (PG&E) Auto-DR efforts, which represents the largestmore » in the state. PG&E's goal was to recruit, install, test and operate 15 megawatts of Auto-DR system capability. We describe the unique delivery approaches, including optimizing the utility incentive structures designed to foster an Auto-DR service provider community. We also show how PG&E's Critical Peak Pricing (CPP) and Demand Bidding (DBP) options were called and executed under the automation platform. Finally, we show the results of the Auto-DR systems installed and operational during 2007, which surpassed PG&E's Auto-DR goals. Auto-DR is being implemented by a multi-disciplinary team including the California Investor Owned Utilities (IOUs), energy consultants, energy management control system vendors, the Lawrence Berkeley National Laboratory (LBNL), and the California Energy Commission (CEC).« less

The HLA-DRB9 gene and the origin of HLA-DR haplotypes.

PubMed

Gongora, R; Figueroa, F; Klein, J

1996-11-01

HLA-DRB9 is a gene fragment consisting of exon 2 and flanking intron sequences. It is located at the extreme end of the DRB subregion, whose other end is demarcated by the DRB1 locus. We sequenced approximately 1400 base pairs of the segment encompassing the DRB9 locus from eight human haplotypes (DR1, DR10, DR2, DR3, DR5, DR6, DR8, and DR9, the DR4 and DR7 having been sequenced by others earlier), as well as two chimpanzee, five gorillas, one orangutan and one macaque haplotype. The analysis of these sequences indicates that the DRB9 locus, which we estimate to be more than 58 million years (my) old, has been coevolving with the DRB1 locus for the last 4.2 my. As a consequence of this coevolution, the human DRB9 alleles fall into groups that correlate with the DRB1 allelic groups and with the gene organization of the human haplotypes. This observation implies that the present-day HLA-DR haplotype groups (DR1, DR51, DR52, DR8, and DR53) were founded more than 4 my ago and have remained intact (barring minor internal rearrangements that did not recombine the DRB1 and DRB9 genes) for this period of time. The haplotypes have been transmitted during speciations from ancestral to emerging species just like allelic lineages at the DRB1 locus. Thus not only allelic but also haplotype polymorphism evolves trans-specifically.

TV series such as "House MD", "Grey´s Anatomy" or "Emergency Room" are well perceived by medical students. Seminars featuring medical TV series such as "House MD" might serve as door-opener to attract medical students to learn more about rare diseases. The TV series "House MD" is troublesome for the main character Dr. House is an excellent diagnostician but at the same time a rather misanthropic person. Therefore, lecturing medicine with the help of "House MD" requires constant evaluation. From 2008 to 2016 we are using the well-known TV series "House MD" continuously to attract medical students and teach them about rare diseases as well as diagnostic strategies. We collected from 213 students a detailed questionnaire assessing their learning experience. 76.6% of our students (n = 157) reported to watching medical dramas on a regular basis. The Dr. House seminar was compared to traditional seminars and our students reported an improved learning effect (69.9%), better concentration (89.7%), higher motivation to participate (88.7%), and more fun (86.7%) (all p<0.001). The students see Dr. House's behavior quite critically. Likert assessment on a 5-point scale identified strong disagreement with Dr. House´s interpersonal skills in dealing with his colleagues (median = 1) and patients (median = 1). At the same time, the students strongly agreed with his outstanding diagnostic (median = 5) and therapeutic capabilities (median = 4). Medical students visiting a Dr. House teaching seminar are highly motivated to learn more about rare diseases. They were positively influenced by TV series such as Dr. House to improve their diagnostic and clinical skills. At the same time, they are critical enough not to see Dr. House as a role model for their own personality. Well performed medical TV shows such as Dr. House can successfully be used in an educational setting to motivate medical students to come into seminars to learn more about rare diseases.

[The Development of First Operating Microscopes from Zeiss Jena and Oberkochen to Series Production].

PubMed

Gudziol, H; Gottschall, R; Luther, E

2017-01-01

Introduction: The history of the first operating microscopes from Zeiss is often confusing, not painstaking and partly contradictory because of the parallel development of Zeiss Jena (East Germany) and Zeiss Oberkochen (West Germany). Methods: To investigate the early beginnings of the construction of the operating microscopes documents of the Carl Zeiss Archive and the Optical Museum in Jena, the memoirs of Prof. Dr. Rosemarie Albrecht and some relevant publications were used. Results: The development of the first Jena operating microscope was initiated in 1949 by the ENT-physician Prof. Dr. Rosemarie Albrecht in the Soviet occupation zone. The first prototype was tested in the University ENT Clinic, Jena since summer of 1950. On the Leipzig Trade Fair in autumn 1952 the VEB Optik Carl Zeiss Jena presented the first operating microscope nationally and internationally. Series production began in 1953. The first operating microscope of Zeiss Oberkochen was primarily developed by technical designers (H. Littmann) as a colposcope. But in the Carl Zeiss Archive no documents could be found related to the cooperation with gynecologists. 1953 the operating microscope (OPMI 1) came into public and its series production started. From this date on, it was adopted by the otologist Prof. Dr. Horst Ludwig Wullstein to the needs of Otorhinolaryngology. Conclusion: The first Zeiss operating microscope came from Jena. The operating microscope from Zeiss Oberkochen had some advantages for the surgeons and won the competition in the future. © Georg Thieme Verlag KG Stuttgart · New York.

The ORAC-DR data reduction pipeline has been used by the Joint Astronomy Centre since 1998. Originally developed for an infrared spectrometer and a submillimetre bolometer array, it has since expanded to support twenty instruments from nine different telescopes. By using shared code and a common infrastructure, rapid development of an automated data reduction pipeline for nearly any astronomical data is possible. This paper discusses the infrastructure available to developers and estimates the development timescales expected to reduce data for new instruments using ORAC-DR.

The diagnosis and treatment pattern using combination of disease and syndrome, fully developing the advantages of both traditional Chinese medicine (TCM) and Western medicine (WM) and being widely used clinically, has been constructed in the long history of TCM. Prof. MA Rou, as a hematology specialist of integrative medicine (IM), uses modern medical equipment to diagnose diseases and takes traditional Chinese medical methods to treat diseases. He is loyal to TCM sciences and refers to the advantages of WM. He holds the essence of MDS lies in toxic stasis according to its pathogenic features. He detoxifies and removes stasis using Qinghuang Powder. Meanwhile, according to patients' clinical manifestations, he summarized two common syndrome types, Pi-Shen yang deficiency syndrome and Gan-Shen yin deficiency syndrome. Better efficacy could be achieved by combining Chinese herbs for tonifying Pi-Shen. In recent years the application of Qinghuang Powder won some achievements in clinical study and experimental study, thus providing scientific reliance for Prof. MA Rou's academic thought on treating MDS.

Dr. Tulp's Anatomy Lesson by Rembrandt: the third day hypothesis.

PubMed

Afek, Arnon; Friedman, Tal; Kugel, Chen; Barshack, Iris; Lurie, Doron J

2009-07-01

An autopsy was an important event in 17th century Holland. Autopsies were held in an 'anatomy theater' and performed according to a fixed protocol that often took up to 3 days to complete. Of the five group portraits painted by Rembrandt over the course of his career, two were anatomy lessons given by Dr. Tulp and Dr. Deyman. An examination of Rembrandt's painting Dr. Tulp's Anatomy Lesson (1632) and an X-ray image of the painting, as compared to other paintings of anatomy lessons from the same period, reveal interesting differences, such as positioning, and light and shadow. Not only was the autopsy not performed according to the usual protocol, but in this painting Rembrandt created a unique dramatic scene in his effort to tell a story. We suggest that Dr. Tulp and Rembrandt "modified" the painting of Dr. Tulp's anatomy lesson to emphasize Dr. Tulp's position as the greatest anatomist of his era--"Vesalius of Amsterdam," and as a way of demonstrating God's greatness by highlighting the hand as a symbol of the most glorious of God's creations.

An HPLC method associated with a thermodynamic analysis to compare the binding of TRAIL and its nanovectorized form to death receptors DR4 and DR5 and their relationship to cytotoxicity.

PubMed

Guillaume, Yves Claude; Lethier, Lydie; André, Claire

2016-11-15

TRAIL is a member of the TNF family of cytokines which induces apoptosis of cancer cells via its binding to its cognate receptors, DR5 a high affinity site and DR4 a site of low affinity. Our working group has recently demonstrated that nanovectorization of TRAIL with single wall carbon nanotubes (abbreviated NPT) enhanced TRAIL affinity to the high affinity site DR5 and increased pro apoptotic potential in different human tumor cell lines. In this paper, the DR4 low affinity site was immobilized on a chromatographic support and the effect of temperature on a wide temperature range 1°C-50°C was studied to calculate the thermodynamic parameters of the binding of TRAIL and NPT to DR4 and DR5 receptors. For the first time the heat capacity changes for the different binding processes were determined. At a physiological pH (7.4) the heat capacity changes for the binding of NPT to DR4 and DR5 were respectively equal to -0.91kJ/molK and -0.28kJ/molK and those obtained for the binding of TRAIL to DR4 and DR5 were respectively equal to -1.54kJ/molK and -1.05kJ/molK. By the use of differential scanning calorimetry (DSC), a phase transition (∼12°C for DR5, ∼4°C for DR4) between a disordered (low temperature) and an ordered (high temperature) solid like state visualized in the receptor structure confirmed the temperature dependence of binding affinity enthalpy ΔH for soluble TRAIL and its nanovectorized form to its cognate receptors. In the low temperature domain, the positive ΔH values contribute non-favourably to the free energy of binding, TRAIL and NPT described similar affinities for DR4 and DR5. For the high temperature domain, negative ΔH values indicated that van der Waals interactions and hydrogen bonding are engaged favourably at the ligand - receptor interface. Above 30°C, their rank-ordered affinities were thus strongly different in the sequence: TRAIL DR4 DR4 DR5 < NPT DR5 . The nanovectorization of TRAIL enhanced its binding to both DR4

Overall properties of the Gaia DR1 reference frame

NASA Astrophysics Data System (ADS)

Liu, N.; Zhu, Z.; Liu, J.-C.; Ding, C.-Y.

Aims: The first Gaia data release (Gaia DR1) provides 2191 ICRF2 sources with their positions in the auxiliary quasar solution and five astrometric parameters - positions, parallaxes, and proper motions - for stars in common between the Tycho-2 catalogue and Gaia in the joint Tycho-Gaia astrometric solution (TGAS). We aim to analyze the overall properties of Gaia DR1 reference frame. Methods: We compare quasar positions of the auxiliary quasar solution with ICRF2 sources using different samples and evaluate the influence on the Gaia DR1 reference frame owing to the Galactic aberration effect over the J2000.0-J2015.0 period. Then we estimate the global rotation between TGAS with Tycho-2 proper motion systems to investigate the property of the Gaia DR1 reference frame. Finally, the Galactic kinematics analysis using the K-M giant proper motions is performed to understand the property of Gaia DR1 reference frame. Results: The positional comparison between the auxiliary quasar solution and ICRF2 shows negligible orientation and validates the declination bias of -0.1mas in Gaia quasar positions with respect to ICRF2. Galactic aberration effect is thought to cause an offset 0.01mas of the Z axis direction of Gaia DR1 reference frame. The global rotation between TGAS and Tycho-2 proper motion systems, obtained by different samples, shows a much smaller value than the claimed value 0.24mas yr-1. For the Galactic kinematics analysis of the TGAS K-M giants, we find possible non-zero Galactic rotation components beyond the classical Oort constants: the rigid part ωYG = -0.38±0.15mas yr-1 and the differential part ω^primeYG = -0.29±0.19mas yr-1 around the YG axis of Galactic coordinates, which indicates possible residual rotation in Gaia DR1 reference frame or problems in the current Galactic kinematical model. Conclusions: The Gaia DR1 reference frame is well aligned to ICRF2, and the possible influence of the Galactic aberration effect should be taken into consideration

The Clinic of Endocrinology, diabetes and metabolic disorders was founded in 1975 by Prof d-r Alexandar Plashevski. Healthcare, educational and scientific activities in the Clinic of Endocrinology are performed in its departments. The Department for hospitalized diabetic and endocrine patients consists of the metabolic and endocrine intensive care unit, the department for diagnosis and treatment of diabetics and endocrine patients, day hospital, the department for education of diabetic patients, and the national center for insulin pump therapy. The Center for Diabetes was established in 1972 by Prof d-r Dimitar Arsov. In 1975, Prof d-r Alexandar Plasheski broadened the activities of the Center for Diabetes. It was dislocated in 1980, with new accommodation outside the clinic. Since then the Center has consisted of several organized units: two specialist outpatient clinics for diabetic patients, biochemical and endocrine laboratory, sub-departments for: diabetic foot, cardiovascular diagnosis, ophthalmology, and urgent interventions. The Department of Endocrinology and Metabolic Disorders for outclinic endocrine patients was established in 1980, and it integrates the following sub-departments: thyrology, andrology, reproductive endocrinology, obesity and lipid disorders and sub-department for osteoporosis. The educational staff of the Clinic of Endocrinology organizes theoretical and practical education about Clinical Investigation and Internal Medicine with credit transfer system course of study of the Medical Faculty, Faculty of Stomatology, postgraduate studies, specializations and sub-specializations. Symposiums, 3 congresses, schools for diabetes and osteoporosis and continuous medical education were also organized. The Clinic of Endocrinology was initiator, organizer, founder and the seat of several medical associations.

2011-03-01

The biennial international conference on Extended Defects in Semiconductors started in 1978 with a meeting in Hünfeld, Germany. Subsequent meetings rotated between Poland, France, Great Britain, Germany, Russia and Italy, culminating in EDS2004 in Chernogolovka, EDS2006 in Halle and EDS2008 in Poitiers. EDS2010 was held at the University of Sussex at Brighton, UK from September 19th to 24th. An extension of the tabulation of this history, which first appeared on the EDS2006 website, is given in the attached PDF. It is with sadness that we note one of the founders of the series, Prof. Dr Helmut Alexander, passed away on 3 December 2009 and we were proud to dedicate EDS2010 to his memory. It has become a tradition to make an award in his name, and this year it was made to Ivan Isacov for his poster "Electrical levels of dislocation networks in p- and n-type silicon". A short and warm celebration of Prof. Dr Alexander's life by his friends and colleagues, Prof. Drs Helmut Gottschalk, Eicke Weber and Wolfgang Schröter, is included in this volume. The conference was a forum for the state-of-the-art of investigation and modelling of extended defects in semiconductors. Scientists from universities, research institutes and industry made contributions to a deeper understanding of extended defects, their interaction with point defects and their role in the development of semiconductor technology. The remit of the conference included extended defects, nanostructures, nanoparticles, quantum dots and interfaces within semiconducting materials ranging from narrow to wide band gaps, including graphene-derived materials and diamond. Scientific interests range from defect geometry, electronic structure, dynamics, spectroscopy, microscopy, reactions and chemistry to introduction mechanisms, such as implantation and strained layers and the operation of devices such as integrated circuits, heterostructures, and solar cells. The organisers were confronted with a long period between

Graft survival rates from deceased donors aged 35 years or less among all primary pediatric kidney transplant recipients in the United States between 1996 and 2004 were retrospectively examined to determine the effect of HLA-DR mismatches on graft survival. Zero HLA-DR-mismatched kidneys had statistically comparable 5-year graft survival (71%), to 1-DR-mismatched kidneys (69%) and 2-DR-mismatched kidneys (71%). When compared to donors less than 35 years of age, the relative rate of allograft failure was 1.32 (p = 0.0326) for donor age greater than or equal to age 35. There was no statistical increase in the odds of developing a panel-reactive antibody (PRA) greater than 30% at the time of second waitlisting, based upon the degree of HLA-A, -B or -DR mismatch of the first transplant, nor was there a 'dose effect' when more HLA antigens were mismatched between the donor and recipient. Therefore, pediatric transplant programs should utilize the recently implemented Organ Procurement and Transplantation Network's (OPTN)allocation policy, which prioritizes pediatric recipients to receive kidneys from deceased donors less than 35 years of age, and should not turn down such kidney offers to wait for a better HLA-DR-matched kidney.

DrImpute: imputing dropout events in single cell RNA sequencing data.

2018-06-08

The single cell RNA sequencing (scRNA-seq) technique begin a new era by allowing the observation of gene expression at the single cell level. However, there is also a large amount of technical and biological noise. Because of the low number of RNA transcriptomes and the stochastic nature of the gene expression pattern, there is a high chance of missing nonzero entries as zero, which are called dropout events. We develop DrImpute to impute dropout events in scRNA-seq data. We show that DrImpute has significantly better performance on the separation of the dropout zeros from true zeros than existing imputation algorithms. We also demonstrate that DrImpute can significantly improve the performance of existing tools for clustering, visualization and lineage reconstruction of nine published scRNA-seq datasets. DrImpute can serve as a very useful addition to the currently existing statistical tools for single cell RNA-seq analysis. DrImpute is implemented in R and is available at https://github.com/gongx030/DrImpute .

Dr. Hugh Latimer Dryden, had many titles after his name in his lifetime. In 1949 he became the director of the National Advisory Committee for Aeronautics (NACA). Dr. Dryden received many accolades and awards both during his life and after his death, but the greatest and most appropriate honor came on March 26, 1976, when NASA renamed the NASA Flight Research Center as the NASA Hugh L. Dryden Flight Research Center. At the dedication ceremony NASA Administrator James C. Fletcher stated: 'in 1924, when the fastest racing planes did well to fly at 280 m.p.h., Dryden was already probing the transonic range of . . . flight. Later in the 1920s, he sought to develop methods of accurately measuring . . . turbulence in wind tunnels. In 1938 he was the first American to deliver the Wright Brothers lecture. His 'Turbulence and the Boundary Layer' became a classic summary on the subject. It is most fitting that this Flight Research Center, with its unique and highly specialized capability for solving aerospace problems, should memorialize the genius of Hugh Dryden.' Dr. Dryden was initially an aerodynamicist with the National Bureau of Standards. He did important early work in high-speed aerodynamics. In 1947 he became the director of aeronautical research for the NACA (a predecessor of the National Aeronautics and Space Administration). Two years later, he became NACA's director, a position he held until 1958 when he became deputy administrator of NASA.

Early onset of diabetes in the proband is the major determinant of risk in HLA DR3-DQ2/DR4-DQ8 siblings.

2014-03-01

Islet autoimmunity is initiated in infancy, and primary prevention trials require children at high genetic risk to be identified before autoantibodies appear. To inform screening strategies, we evaluated risks of autoimmunity and diabetes associated with HLA DR3-DQ2/DR4-DQ8 in U.K. families. Extended HLA haplotypes were determined in 2,134 siblings from the Bart's-Oxford Study followed to a median age of 22 years. Risks of diabetes and islet autoimmunity (more than two antibodies) were estimated by survival analysis. Of 138 informative DR3-DQ2/DR4-DQ8 siblings, 63% shared both haplotypes with their diabetic proband, 29% shared one, and 8% shared neither. In HLA-identical DR3-DQ2/DR4-DQ8 siblings, the cumulative risk of diabetes by age 15 was 17% (vs. 6% in those sharing one haplotype or none; P = 0.095). Risk varied, however, with the age at the onset of diabetes in the proband; the cumulative risk of autoimmunity and/or diabetes by age 15 was 61% in siblings of probands diagnosed when younger than 10 years old compared with only 4.7% in those diagnosed after age 10 years (P < 0.001). The age of the proband at diagnosis, but not HLA haplotype sharing, was an independent determinant of sibling risk. This suggests that non-HLA genes or epigenetic/environmental factors that accelerate the progression of type 1 diabetes in the proband strongly affect risk in siblings.

A survey of motif finding Web tools for detecting binding site motifs in ChIP-Seq data

PubMed Central

2014-01-01

Abstract ChIP-Seq (chromatin immunoprecipitation sequencing) has provided the advantage for finding motifs as ChIP-Seq experiments narrow down the motif finding to binding site locations. Recent motif finding tools facilitate the motif detection by providing user-friendly Web interface. In this work, we reviewed nine motif finding Web tools that are capable for detecting binding site motifs in ChIP-Seq data. We showed each motif finding Web tool has its own advantages for detecting motifs that other tools may not discover. We recommended the users to use multiple motif finding Web tools that implement different algorithms for obtaining significant motifs, overlapping resemble motifs, and non-overlapping motifs. Finally, we provided our suggestions for future development of motif finding Web tool that better assists researchers for finding motifs in ChIP-Seq data.

Diabetic retinopathy (DR) is the common cause of diabetic vascular complications. The NOD-like receptor (NLR) family, pyrin domain containing 1 (NLRP1), also known as NALP1, inflammasome is the first member of the NLR family to be discovered, playing an important role in inflammatory response. However, its effect on DR development has not been reported. In the study, the wild type (WT) and NLRP1 -/- mice were injected with streptozotocin (STZ) to induce DR. The results indicated that NLRP1 -/- significantly increased bodyweight reduction and decreased blood glucose levels induced by STZ. WT/DR mice exhibited higher levels of NLRP1 in retinas. NLRP1 -/- ameliorated retinal abnormalities in DR mice using H&E staining. In addition, attenuated avascular areas and neovascular tufts were also observed in NLRP1 -/- /DR mice. The levels of pro-inflammatory cytokines in serum and retinas were highly induced in WT/DR mice, whereas being markedly reduced by NLRP1 -/- . In addition, vascular endothelial growth factor (VEGF) and Iba1 expressions induced by STZ in serum or retinas were significantly down-regulated in NLRP1 -/- /DR mice. Consistently, NLRP1 -/- attenuated ASC and Caspase-1 expressions in retinas of DR mice. Compared to WT/DR group, NLRP1 -/- markedly decreased retina p-nuclear factor-κB (NF-κB), interleukin-1β (IL-1β) and IL-18 levels. And similar results were confirmed in vitro that suppressing NLRP1/ASC inflammasome ameliorated inflammatory response in fructose-treated retinal ganglion cells. The results above indicated that the modulation of NLRP1 inflammasome might be a promising strategy for DR therapy. Copyright © 2018. Published by Elsevier Inc.

The birth of the Degree in Dentistry in Italy has been very troubled, and only in 1980 saw its effective implementation. Very "instructive" in this regard is the history on the establishment in 1924 (the period of the seizure of power by Fascism) of a "National School of Dentistry" at the University of Rome, which was withdrawn after only ten months. The biggest supporter and proponent of the School, Prof. Angelo Chiavaro, after a few years, was "punished" with the transfer from the University of Rome to that of Genoa. We present some brief notes on the biography of this courageous pioneer and the matter of which he was the protagonist.

Gaia DR1 is based on observations collected between 25 July 2014 and 16 September 2015. Gaia DR1 contains positions (RA,DE) and G magnitudes for all sources with acceptable formal standard errors on positions. Positions and individual uncertainties are computed using a generic prior and Bayes' rule (detailed description in "Gaia astrometry for stars with too few observations. A Bayesian approach", Michalik et al., 2015A&A...583A..68M). The five-parameter astrometric solution - positions, parallaxes, and proper motions - for stars in common between the Tycho-2 Catalogue and Gaia is contained in Gaia DR1. This part of Gaia DR1 is based on the Tycho-Gaia Astrometric Solution (paper with detailed description (Michalik et al., 2015A&A...574A.115M); paper describing theory and background (Michalik et al., 2014A&A...571A..85M); paper describing quasar extension (Michalik & Lindegren, 2016A&A...586A..26M)). At the beginning of the routine phase, for a period of 4 weeks, a special scanning mode repeatedly covering the ecliptic poles on every spin was executed for calibration purposes.

This special issue of the "Cardiovascular Drug Reviews" is dedicated in memory of Dr. Edward H. Ahrens, Jr., who died on Dec. 9th, 2000 at the Princeton Medical Center in New Jersey at the age of 85. Dr. Ahrens was the Director of the Lipid Metabolism Laboratory at the Rockefeller University. Dr. Alexander Scriabine conceived the idea for the issue at the special memorial symposium held at the Rockefeller University on Feb. 05, 2002 under the auspices of The New York Lipid and Vascular Biology Research Club. Dr. Ahrens was the first president of the club. He started this club with Drs. Howard Eder and DeWitt Goodman. Dr. Eder thought that it would be a fitting attribute to honor one of the founding fathers of the club by hosting a memorial symposium. I, as the President of the club for that academic year, had no hesitation in accepting the proposal. This year will be the 40th anniversary of the club and its continued success provides a glimpse of the fine legacy left behind by Dr. Ahrens. Dr. Ahrens also played a pivotal role in the establishment of the Journal of Lipid Research. This is the 43rd year of the journal and in this commemorative issue we are reproducing a review he wrote for the 25th anniversary of the journal. I was never personally acquainted with Dr. Ahrens. However, I am honored that I got this opportunity to pay tribute to a great scientist whose work has contributed immensely to the progress of lipid research. He was a person who touched many lives and still continues to do so. My involvement in the remembrance of Dr. Ahrens shows that science not only impacts your contemporaries but also generations that follow you. Scientific research is a journey where you can leave your trails behind and be remembered for your work long after your departure from this world.

The Goddard Space Flight Center was named in honor of Dr. Robert Goddard, a pioneer in rocket development. Dr. Goddard received patents for a multi-stage rocket and liquid propellants in 1914 and published a paper describing how to reach extreme altitudes six years later. That paper, "A Method of Reaching Extreme Altitudes," detailed methods for raising weather-recording instruments higher than what could be achieved by balloons and explained the mathematical theories of rocket propulsion. The paper, which was published by the Smithsonian Institution, also discussed the possibility of a rocket reaching the moon-a position for which the press ridiculed Goddard. Yet several copies of the report found their way to Europe, and by1927, the German Rocket Society was established, and the German Army began its rocket program in 1931. Goddard, meanwhile, continued his work. By 1926, he had constructed and tested the first rocket using liquid fuel. Goddard's work largely anticipated in technical detail the later German V-2 missiles, including gyroscopic control, steering by means of vanes in the jet stream of the rocket motor, gimbal-steering, power-driven fuel pumps and other devices.

DR-induced escape of O and C from early Mars

NASA Astrophysics Data System (ADS)

Zhao, Jinjin; Tian, Feng; Ni, Yufang; Huang, Xiaomeng

2017-03-01

Energetic particles produced in Dissociative recombination (DR) reactions could escape planets with low gravity, such as Mars, if they could overcome collisions with the surrounding background gases. In this work, a 3-D Monte Carlo model is developed to study these photochemical escape processes on early Mars. Although the DR reaction rates of O2+, CO2+, and CO+ increase monotonically with solar soft X-ray and extreme ultraviolet (XUV) flux, the peak of the calculated DR-induced escape rates of O is near 3 × XUV, and the DR-induced escape rates of C increase with XUV until 10 × XUV. The non-monotonic behavior can be explained by the increased column densities of background species in high XUV conditions, which can deflect energetic particles through collisions more efficiently. At 20 × XUV, CO+ DR is the main source of escaping O and C, and the escape of secondary particles could contribute to 30∼40% and 10% of the total escape of O and C respectively. The time-integrated DR-induced escape of O and C is equivalent to 1 m of H2O and 20 mbar of CO2 escaping early Mars since 4.5 billion years ago. The accumulated CO2 loss is much lower than what's needed to explain the carbon isotopic ratios on Mars and much lower than the total CO2 needed to warm up early Mars. If more vigorous escape mechanisms were absent on early Mars, substantial inventories of volatiles have not been detected yet.

The evolution of Martian atmosphere is a key aspect to understand the habitability of Mars in time. The distributions of neutral atoms above the exobase of ancient Mars (corona) is important for understanding the interactions between the corona and the solar wind, which could help improving our understanding of the evolution of Martian atmosphere. In this work, a 3-D Monte Carlo Model is built to simulate Martian corona in different period of Mars history based on thermosphere structure corresponding to 1, 3, 10, and 20 times present solar XUV conditions and dissociative recombination (DR) reaction profiles. DR reactions of O2+, CO2+, and CO+ are considered as the sources of primary O and C. Secondary O and C atoms, which are formed through collisions between primaries and background species. We will discuss the dependence of physical properties of Martian corona as functions of solar XUV flux and DR reactions. We will also discuss the potential importance of CO+ DR as a contributor to Martian corona.

We present Kepler's final planet candidate catalog, which is based on the Q1--Q17 DR25 data release and was created to allow for accurate calculations of planetary occurrence rates. We discuss improvements made to our fully automated candidate vetting procedure, which yields specific categories of false positives and a disposition score value to indicate decision confidence. We present the use of light curve inversion and scrambling, in addition to our continued use of pixel-level transit injection, to produce artificial planet candidates and false positives. Since these simulated data sets were subjected to the same automated vetting procedure as the real data set, we are able to measure both the completeness and reliability of the catalog. The DR25 catalog, source code, and a multitude of completeness and reliability data products are available at the Exoplanet Archive (http://exoplanetarchive.ipac.caltech.edu). The DR25 light curves and pixel-level data are available at MAST (http://archive.stsci.edu/kepler).

Association of HLA-DR1 with the allergic response to the major mugwort pollen allergen: molecular background.

Mugwort pollen allergens represent the main cause of pollinosis in late summer. The major allergen, Art v 1, contains only one single immunodominant, solely HLA-DR-restricted T cell epitope (Art v 125-36). The frequency of HLA-DRB1*01 is highly increased in mugwort-allergic individuals and HLA-DR1 serves as restriction element for Art v 125-36. However, Art v 125-36 also binds to HLA-DR4 with high affinity and DR1-restricted Art v 125-36 -specific T cell receptors can be activated by HLA-DR4 molecules. To understand the predominance of HLA-DR1 in mugwort allergy in spite of the degeneracy in HLA/peptide-binding and TCR-recognition, we investigated the molecular background of Art v 125-36 /MHC/TCR interactions in the context of HLA-DR1 compared to -DR4. The majority of Art v 125-36 -specific T cell lines and clones from HLA-DR1 carrying, mugwort pollen-allergic donors reacted to synthetic and naturally processed Art v 1-peptides when presented by HLA-DR1 or HLA-DR4 expressing antigen presenting cells. However, at limiting peptide concentrations DR1 was more effective in T cell stimulation. In addition, the minimal epitope for 50% of Art v 125-36 -specific T cells was shorter for DR1 than for DR4. In vitro binding assays of Art v 125-36 mutant peptides to isolated DR1- and DR4-molecules indicated similar binding capacities and use of the same register. In silico simulation of Art v 125-36 binding to HLA-DR1 and -DR4 suggested similar binding of the central part of the peptide to either molecule, but a higher flexibility of the N- and C-terminal amino acids and detachment at the C-terminus in HLA-DR1. The predominance of HLA-DR1 in the response to Art v 125-36 may be explained by subtle conformation changes of the peptide bound to DR1 compared to DR4. Computer simulation supported our experimental data by demonstrating differences in peptide mobility within the HLA-DR complex that may influence TCR-binding. We suggest that the minor differences observed in vitro may

Dopamine receptor 2 (DR2) may be a biomarker for various types of cancer. Ovarian cancer cells overexpress DR2; therefore, blocking DR2 may be a novel treatment strategy for ovarian cancer. Thioridazine, a DR2 blocker, has antineoplastic activity in a variety of cancer cells. In view of the requirement for novel therapeutic agents in ovarian cancer, the present study aimed to determine the potential effects of thioridazine in vitro and in vivo. It was revealed that the DR2 blocker thioridazine induced cell death in a dose-dependent manner in ovarian cancer cells. Thioridazine treatment induced apoptosis and autophagy, which may be attributed to an increased level of reactive oxygen species and associated DNA damage. Additionally, the expression of various proteins increased with oxidative stress, including nuclear factor E2-related factor 2, which is a pivotal transcriptional factor involved in cellular responses to oxidative stress. Heme oxygenase 1, NAPDH quinone dehydrogenase 1 and hypoxia inducible factor-1α and phosphorylated (p)-protein kinase B expression was significantly decreased, and the expression level of p-extracellular signal-related kinases and p-P38 was increased. Using 3-methyl adenine to inhibit autophagy caused the rate of apoptosis to increase. Thioridazine inhibited the growth of SKOV3 xenografts in nude mice. The present study demonstrated that the DR2 blocker thioridazine exhibited anticancer effects in vitro and in vivo, suggesting that thioridazine may be used as a potential drug in ovarian cancer therapy.

KEY MESSAGE : Auxin responsive promoter DR5 reporter system is functional in Populus to monitor auxin response in tissues including leaves, roots, and stems. We described the behavior of the DR5::GUS reporter system in stably transformed Populus plants. We found several similarities with Arabidopsis, including sensitivity to native and synthetic auxins, rapid induction after treatment in a variety of tissues, and maximal responses in root tissues. There were also several important differences from Arabidopsis, including slower time to maximum response and lower induction amplitude. Young leaves and stem sections below the apex showed much higher DR5 activity than did older leaves and stems undergoing secondary growth. DR5 activity was highest in cortex, suggesting high levels of auxin concentration and/or sensitivity in this tissue. Our study shows that the DR5 reporter system is a sensitive and facile system for monitoring auxin responses and distribution at cellular resolution in poplar.

This chapter describes the photometric variability processing of the Gaia DR1 data. Coordination Unit 7 is responsible for the variability analysis of over a billion celestial sources. In particular the definition, design, development, validation and provision of a software package for the data processing of photometrically variable objects. Data Processing Centre Geneva (DPCG) responsibilities cover all issues related to the computational part of the CU7 analysis. These span: hardware provisioning, including selection, deployment and optimisation of suitable hardware, choosing and developing software architecture, defining data and scientific workflows as well as operational activities such as configuration management, data import, time series reconstruction, storage and processing handling, visualisation and data export. CU7/DPCG is also responsible for interaction with other DPCs and CUs, software and programming training for the CU7 members, scientific software quality control and management of software and data lifecycle. Details about the specific data treatment steps of the Gaia DR1 data products are found in Eyer et al. (2017) and are not repeated here. The variability content of the Gaia DR1 focusses on a subsample of Cepheids and RR Lyrae stars around the South ecliptic pole, showcasing the performance of the Gaia photometry with respect to variable objects.

DR2DI: a powerful computational tool for predicting novel drug-disease associations

NASA Astrophysics Data System (ADS)

Finding the new related candidate diseases for known drugs provides an effective method for fast-speed and low-risk drug development. However, experimental identification of drug-disease associations is expensive and time-consuming. This motivates the need for developing in silico computational methods that can infer true drug-disease pairs with high confidence. In this study, we presented a novel and powerful computational tool, DR2DI, for accurately uncovering the potential associations between drugs and diseases using high-dimensional and heterogeneous omics data as information sources. Based on a unified and extended similarity kernel framework, DR2DI inferred the unknown relationships between drugs and diseases using Regularized Kernel Classifier. Importantly, DR2DI employed a semi-supervised and global learning algorithm which can be applied to uncover the diseases (drugs) associated with known and novel drugs (diseases). In silico global validation experiments showed that DR2DI significantly outperforms recent two approaches for predicting drug-disease associations. Detailed case studies further demonstrated that the therapeutic indications and side effects of drugs predicted by DR2DI could be validated by existing database records and literature, suggesting that DR2DI can be served as a useful bioinformatic tool for identifying the potential drug-disease associations and guiding drug repositioning.

We present candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4, 24 high confidence candidates of tidal streams GD-1, Cetus Polar and Orphan respectively. We also list from the SDSS DR9 spectroscopic catalog 59, 118, 10 high confidence candidates of tidal streams Cetus Polar, Orphan and Pal 5, respectively. Furthermore, we find 7 high confidence candidates of the Pal 5 tidal stream in APOGEE data. Compared with SDSS, the new candidates from LAMOST DR3 are brighter, so that together, more of the color-magnitude diagram, including the giant branch can be explored. Analysis of SDSS data shows that there are 3 metallicity peaks of the Orphan stream and also shows some spatial separation. LAMOST data confirms multiple metallicities in this stream. The metallicity, given by the higher resolution APOGEE instrument, of the Pal 5 tidal stream is [Fe/H]more » $$\\sim -1.2$$, higher than that given earlier by SDSS spectra. Here, many previously unidentified stream members are tabulated here for the first time, along with existing members, allowing future researchers to further constrain the orbits of these objects as they move within the Galaxy's dark matter potential.« less

The amount of information being generated about our planet is increasing at an exponential rate, but it must be easily accessible in order to apply it to the global needs relating to the state of the Earth. Currently, information about the state of the Earth, relevant services, analysis results, applications and tools are accessible in a very scattered and uncoordinated way, often through individual initiatives from Earth Observation mission operators, scientific institutes dealing with ground measurements, service companies, data catalogues, etc. A dedicated infrastructure providing transparent access to all this will support Earth Science communities by allowing them to easily and quickly derive objective information and share knowledge based on all environmentally sensitive domains. The use of high-speed networks (GÉANT) and the experimentation of new technologies, like BitTorrent, will also contribute to better services for the Earth Science communities. GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories), an ESA-led, European Commission (EC)-funded two-year project, is taking the lead in providing reliable, easy, long-term access to Earth Science data via the Internet. This project will allow scientists from different Earth Science disciplines located across Europe to locate, access, combine and integrate historical and fresh Earth-related data from space, airborne and in-situ sensors archived in large distributed repositories. GENESI-DR builds a federated collection of heterogeneous digital Earth Science repositories to establish a dedicated infrastructure providing transparent access to all this and allowing Earth Science communities to easily and quickly derive objective information and share knowledge based on all environmentally sensitive domains. The federated digital repositories, seen as services and data providers, will share access to their resources (catalogue functions, data access, processing services etc

Background The main genomic region controlling the predisposition to type 1 diabetes is the Human Leukocyte Antigens (HLA) class II of the major histocompatibility complex. Association with different HLA types depends also on the studied populations. In our investigation, we tried to measure the phenotypic HLA class II association frequencies of DR3 and/or DR4 antigens, using a serologic method called microlymphocytotoxicity analysis, in diabetic and nondiabetic (ND) subjects originating from the west-Algerian region of Tlemcen. The aim of the present study was to determine which HLA DR antigens represent a high susceptibility to develop the disease in this area. Using a case-control retrospective study design, we randomly recruited ninety-one related subjects, 39 type 1 diabetics and 52 ND as controls, at the Internal Medicine Board of Medical Centre University of Tlemcen. Results DR3 antigen frequencies were comparable between the type 1 diabetics and the ND subjects and showed no association with the disease (p = 1.000, OR = 0.95), whereas DR4 and DR3DR4 antigens were associated with susceptibility to develop type 1 diabetes (DR4; OR = 2.10, DR3DR4; OR = 1.30). Also, no incidence for DR3 (p = 0.2646) or DR3DR4 (p = 0.0699) antigen frequencies was related to the sex ratio. However, significant differences in HLA DR4 frequencies between type 1 diabetics and ND were found to be related to sex (p = 0.0085). Conclusion Taken together, our investigation showed that the strongest association with type 1 diabetes was noticed in the presence of HLA DR4 antigens followed by DR3DR4 antigens. This study highlighted a characteristic of Tlemcen population; a history of consanguineous marriages. Association studies between the disease and genetic polymorphisms should be undertaken in a population where consanguinity is more limited to reduce confounding in result interpretations.

Bent-core fiber structure: Experimental and theoretical studies of fiber stability

NASA Astrophysics Data System (ADS)

Bailey, C.; Gartland, E.; Jakli, A.

2007-03-01

Recent studies have shown that bent core liquid crystals in the B7 and B2 phases can form stable freestanding fibers with a so called ``jelly-roll'' layer configuration, which means that the smectic layers would be arranged in concentric cylindrical shells. This configuration shows layer curvature is necessary for fiber stability. Classically this effect would destabilize the fiber configuration because of the energy cost of layer distortions and surface tension. We propose a model that can predict fiber stability in the experimentally observed range of a few micrometers, by assuming that layer curvature can be stabilized by including a term dealing with the linear divergence of the polarization direction if the polarization is allowed to have a component normal to the smectic layers. We show that this term can stabilize the fiber configuration if its strength is larger than the surface tension. We also propose an entropic model to explain the strength of this term by considering steric effects. Finally we will take results from this model and apply them to better understand experimental findings of bent-core fibers. Financial support by NSF FRG under contract DMS-0456221.

2012 DR30 is a recently discovered solar system object on a unique orbit, with a high eccentricity of 0.9867, a perihelion distance of 14.54 AU, and a semi-major axis of 1109 AU, in this respect outscoring the vast majority of trans-Neptunian objects (TNOs). We performed Herschel/PACS and optical photometry to uncover the sizeand albedo of 2012 DR30, together with its thermal and surface properties. The body is 185 km in diameter and has a relatively low V-band geometric albedo of ~8%. Although the colours of the object indicate that 2012 DR30 is an RI taxonomy class TNO or Centaur, we detected an absorption feature in the Z-band that is uncommon among these bodies. A dynamical analysis of the target's orbit shows that 2012 DR30 moves on a relatively unstable orbit and was most likely only recently placed on its current orbit from the most distant and still highly unexplored regions of the solar system. If categorised on dynamical grounds 2012 DR30 is the largest Damocloid and/or high inclination Centaur observed so far. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.Appendices are available in electronic form at http://www.aanda.org

The ESA Gaia mission will release its first major all sky astrometric catalogue (Gaia DR2), of more than 1.3 billion stars in our Galaxy, on 25 April 2018.This presentation will provide an overview of the Gaia mission, focussing on the significant scientific potential of the Gaia DR2 release. This is based on 22 months of input data and allows for a full Gaia stand alone astrometric solution, including parallaxes and proper motions, of over 1.3 billion sources. The astrometric uncertainties in Gaia DR2 will be at the level of tens of micro-arcsec for sources G<15.The Gaia DR2 release provides not only high precision full five parameter astrometry, but also a complete photometric catalogue of the sources on an all sky homogeneous photometric system in the Gaia G band and broad bands G_BP and G_RP. The release will include median radial velocities for more than six million stars (brighter that G_RVS = 12) together with a set of astrophysical parameters (including stellar temperatures) for some 150 million stars. Finally the Gaia DR2 release will include a set of additional data products including the light curves of more than half a million variable stars, and the positions of more than thirteen thousand objects in our Solar System.Together with the Gaia DR2 data products and associated release documentation, a small number of performance verification papers, using Gaia DR2 data only to provide new insights into a number of key areas of Gaia science, will be published in a special edition of A&A. These will provide demonstrations of the scientific potential of the Gaia DR2 catalogue, and also highlight some of the issues and limitations involved in the use of the Gaia DR2 data.The Gaia mission and Gaia Data Releases are made possible through the dedication and expertise of the community scientists and engineers involved in the design, construction, and operation of Gaia (led by ESA) and the collaboration of some 450 scientists and software engineers responsible for

Star Formation in the DR21 Region (B)

[figure removed for brevity, see original site] Annotated mosaic

Hidden behind a shroud of dust in the constellation Cygnus is an exceptionally bright source of radio emission called DR21. Visible light images reveal no trace of what is happening in this region because of heavy dust obscuration. In fact, visible light is attenuated in DR21 by a factor of more than 10,000,000,000,000,000,000,000,000,000,000,000,000,000 (ten thousand trillion heptillion).

New images from NASA's Spitzer Space Telescope allow us to peek behind the cosmic veil and pinpoint one of the most massive natal stars yet seen in our Milky Way galaxy. The never-before-seen star is 100,000 times as bright as the Sun. Also revealed for the first time is a powerful outflow of hot gas emanating from this star and bursting through a giant molecular cloud.

The upper image is a large-scale mosaic assembled from individual photographs obtained with the InfraRed Array Camera (IRAC) aboard Spitzer. The image covers an area about two times that of a full moon. The mosaic is a composite of images obtained at mid-infrared wavelengths of 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8 microns (red). The brightest infrared cloud near the top center corresponds to DR21, which presumably contains a cluster of newly forming stars at a distance of 10,000 light-years.

Protruding out from DR21 toward the bottom left of the image is a gaseous outflow (green), containing both carbon monoxide and molecular hydrogen. Data from the Spitzer spectrograph, which breaks light into its constituent individual wavelengths, indicate the presence of hot steam formed as the outflow heats the surrounding molecular gas. Outflows are physical signatures of processes that create supersonic beams, or jets, of gas. They are usually accompanied by discs of material around the new star, which likely contain the materials from which future planetary systems are formed. Additional newborn stars

Signaling events that regulate central nervous system (CNS) angiogenesis and blood-brain barrier (BBB) formation are only beginning to be elucidated. By evaluating the gene expression profile of mouse vasculature, we identified DR6/TNFRSF21 and TROY/TNFRSF19 as regulators of CNS-specific angiogenesis in both zebrafish and mice. Furthermore, these two death receptors interact both genetically and physically and are required for vascular endothelial growth factor (VEGF)-mediated JNK activation and subsequent human brain endothelial sprouting in vitro. Increasing beta-catenin levels in brain endothelium upregulate DR6 and TROY, indicating that these death receptors are downstream target genes of Wnt/beta-catenin signaling, which has been shown to be required for BBB development. These findings define a role for death receptors DR6 and TROY in CNS-specific vascular development. Copyright © 2012 Elsevier Inc. All rights reserved.

Female and male adolescents in Germany are increasingly using the Internet to find information about sexuality and sexual health. This review paper summarizes what we know about the status quo of online sexuality education in Germany.Based on a systematic literature review including 40 papers from international, peer-reviewed journals spanning 2010-2017, this paper first describes different aspects of the sexuality-related online search behavior of adolescents: its prevalence, predictors, topics and contexts. One main finding is the fact that adolescents use a computer or smartphone to type their sexuality-related questions into the search engine Google or the search engine of the video platform YouTube.Based on 54 online searches, this paper subsequently presents the kind of sexuality-related online content adolescents find if they ask "Dr. Google" for sexual advice; a collection of 1236 authentic sexuality-related questions of adolescents was used for this analysis. It turned out that online sexuality education offered by leading professional organizations like the BZgA ("Bundeszentrale für gesundheitliche Aufklärung") or pro familia was nearly invisible, while numerous other providers of online sex education consistently appeared in the top Google search results. Among them were the "Dr. Sommer" team of the youth magazine Bravo; online healthcare and advice portals; online forums; the online encyclopedia Wikipedia and, above all, sex education channels on YouTube. In this paper, the latter are presented in more detail for the first time.The third part of the paper addresses the quality of online sexual education over four main areas of quality evaluation. The presentation of the status quo ends with some recommendations both for future research and for sexuality education in practice.

Mrs. Maria van der Hoeven, the Dutch Minister of Education, Culture and Science, who travelled to the Republic of Chile, arrived at the ESO Paranal Observatory on Friday afternoon, May 13, 2005. The Minister was accompanied, among others, by the Dutch Ambassador to Chile, Mr. Hinkinus Nijenhuis, and Mr. Cornelis van Bochove, the Dutch Director of Science. The distinguished visitors were able to acquaint themselves with one of the foremost European research facilities, the ESO Very Large Telescope (VLT), during an overnight stay at this remote site, and later, with the next major world facility in sub-millimetre and millimetre astronomy, the Atacama Large Millimeter Array (ALMA). At Paranal, the guests were welcomed by the ESO Director General, Dr. Catherine Cesarsky; the ESO Council President, Prof. Piet van der Kruit; the ESO Representative in Chile, Prof. Felix Mirabel; the Director of the La Silla Paranal Observatory, Dr. Jason Spyromilio; by one of the Dutch members of the ESO Council, Prof. Tim de Zeeuw; by the renowned astrophysicist from Leiden, Prof. Ewine van Dishoek, as well as by ESO staff members. The visitors were shown the various high-tech installations at the observatory, including many of the large, front-line VLT astronomical instruments that have been built in collaboration between ESO and European research institutes. Explanations were given by ESO astronomers and engineers and the Minister gained a good impression of the wide range of exciting research programmes that are carried out with the VLT. Having enjoyed the spectacular sunset over the Pacific Ocean from the Paranal deck, the Minister visited the VLT Control Room from where the four 8.2-m Unit Telescopes and the VLT Interferometer (VLTI) are operated. Here, the Minister was invited to follow an observing sequence at the console of the Kueyen (UT2) and Melipal (UT3) telescopes.

Nm23 gene family has been associated with metastasis suppression and differentiation. We studied DR-nm23 during neuroblastoma cells differentiation. DR-nm23 expression increased after retinoic acid induction of differentiation in human cell lines SK-N-SH and LAN-5. In several cell lines, overexpression of DR-nm23 was associated with more differentiated phenotypes. SK-N-SH cells increased vimentin expression, increased deposition of collagen type IV, modulated integrin expression, and underwent growth arrest; the murine neuroblastoma cell line N1E-115 showed neurite outgrowth and a striking enhancement of beta1 integrin expression. Up-regulation of beta1 integrin was specifically responsible for the increase in the adhesion to collagen type I-coated plates. Finally, cells overexpressing DR-nm23 were unable to growth in soft agar. In conclusion, DR-nm23 expression is directly involved in differentiation of neuroblastoma cells, and its ability to affects the adhesion to extracellular substrates and to inhibit growth in soft agar suggests an involvement in the metastatic potential of neuroblastoma.

Abstract The authors assessed an expansion of Vermont's Dr. Dynasaur program that would cover all residents age 25 and younger. The current Dr. Dynasaur program combines Vermont's Medicaid program and Child Health Insurance Program for children ages 0 through 18 to provide a seamless insurance program for those with family incomes below 317 percent of the federal poverty level. The authors used RAND's COMPARE-VT microsimulation model with Vermont-specific demographic, economic, and actuarial data to estimate the effects on health insurance coverage, costs, and premiums. They also identified the new revenues required to fund the program expansion and explored three alternative financing strategies to raise those funds: (1) an increase in the Vermont income tax, (2) a Vermont payroll tax, and (3) a Vermont business enterprise tax. The authors found that enrollment would increase by more than 260 percent under the 100-percent enrollment scenario and by nearly 200 percent under the 70-percent enrollment scenario by 2019. Not surprisingly, the children and young adults who move off employer-sponsored insurance (ESI) and into Dr. Dynasaur 2.0 have considerably lower expected health care costs than those who remain on ESI, increasing the per-person premiums by nearly $1,000 for those remaining enrolled in ESI. Annual health care expenditures per person for children and young adults in 2019 are estimated at $4,325 with Medicare prices. The combination of increased reimbursement rates, large increases in enrollment, and relatively low Dr. Dynasaur premiums (no more than $720 per year) will require significant new tax revenues to meet program obligations.

Idiopathic pulmonary fibrosis (IPF) is a progressive, debilitating, and fatal lung disease of unknown aetiology with no current cure. The pathogenesis of IPF remains unclear but repeated alveolar epithelial cell (AEC) injuries and subsequent apoptosis are believed to be among the initiating/ongoing triggers. However, the precise mechanism of apoptotic induction is hitherto elusive. In this study, we investigated expression of a panel of pro-apoptotic and cell cycle regulatory proteins in 21 IPF and 19 control lung tissue samples. We reveal significant upregulation of the apoptosis-inducing ligand TRAIL and its cognate receptors DR4 and DR5 in AEC within active lesions of IPF lungs. This upregulation was accompanied by pro-apoptotic protein p53 overexpression. In contrast, myofibroblasts within the fibroblastic foci of IPF lungs exhibited high TRAIL, DR4 and DR5 expression but negligible p53 expression. Similarly, p53 expression was absent or negligible in IPF and control alveolar macrophages and lymphocytes. No significant differences in TRAIL expression were noted in these cell types between IPF and control lungs. However, DR4 and DR5 upregulation was detected in IPF alveolar macrophages and lymphocytes. The marker of cellular senescence p21(WAF1) was upregulated within affected AEC in IPF lungs. Cell cycle regulatory proteins Cyclin D1 and SOCS3 were significantly enhanced in AEC within the remodelled fibrotic areas of IPF lungs but expression was negligible in myofibroblasts. Taken together these findings suggest that, within the remodelled fibrotic areas of IPF, AEC can display markers associated with proliferation, senescence, and apoptotosis, where TRAIL could drive the apoptotic response. Clear understanding of disease processes and identification of therapeutic targets will direct us to develop effective therapies for IPF.

We present the data release (DR) 5 catalogue of white dwarf-main sequence (WDMS) binaries from the Large Area Multi-Object fiber Spectroscopic Telescope (LAMOST). The catalogue contains 876 WDMS binaries, of which 757 are additions to our previous LAMOST DR1 sample and 357 are systems that have not been published before. We also describe a LAMOST-dedicated survey that aims at obtaining spectra of photometrically-selected WDMS binaries from the Sloan Digital Sky Survey (SDSS) that are expected to contain cool white dwarfs and/or early type M dwarf companions. This is a population under-represented in previous SDSS WDMS binary catalogues. We determine the stellar parameters (white dwarf effective temperatures, surface gravities and masses, and M dwarf spectral types) of the LAMOST DR5 WDMS binaries and make use of the parameter distributions to analyse the properties of the sample. We find that, despite our efforts, systems containing cool white dwarfs remain under-represented. Moreover, we make use of LAMOST DR5 and SDSS DR14 (when available) spectra to measure the Na I λλ 8183.27, 8194.81 absorption doublet and/or Hα emission radial velocities of our systems. This allows identifying 128 binaries displaying significant radial velocity variations, 76 of which are new. Finally, we cross-match our catalogue with the Catalina Surveys and identify 57 systems displaying light curve variations. These include 16 eclipsing systems, two of which are new, and nine binaries that are new eclipsing candidates. We calculate periodograms from the photometric data and measure (estimate) the orbital periods of 30 (15) WDMS binaries.

The influence of the work of Dr. Guillermo Contreras Da Silva and his colaborators on the evolution of microbiology in Chile is briefly analyzed. Dr. Contreras was trained in modern virology at Yale University with Dr. J. Melnick under the sponsorhip of the Rockefeller Foundation. During this training, he used serological methods to classify Cocksakie viruses. After his return to Chile, he studied the epidemiology of enteroviruses, including poliovirus. His laboratory, the country's first in modern virology, took an active role in Chile's first Sabin polio vaccination in 1961. Dr. Contreras and his group transformed the teaching and the character of microbiology in Chile from a descriptive medically oriented discipline into an autonomous, quantitative and experimental science. They modernized microbiology with the introduction of molecular biology and microbial genetics and fostered collaborations with allied biological sciences. Dr. Contreras was a Guggenheim Fellow, and until his retirement, was the Chief of the Viral Products Division, Bureau of Biologies, Ottawa, Canada.

ISAAC Photometric Comparison of ECLIPSE Jitter and the ORAC-DR Equivalent Recipe for ISAAC

2005-12-01

Motivated by a request from astronomers demanding accurate and consistent infrared photometry, I compare the photometry and quality of mosaics generated by the ECLIPSE jitter task and the ORAC-DR JITTER_SELF_FLAT recipe in two fields. The current (v4.9.0) ECLIPSE produces photometry a few percent fainter than ORAC-DR; the systematic trend with magnitude seen in v4.4.1 is now removed. Random errors arising from poor flat-fielding are not resolved. ECLIPSE generates noisier mosaics; ORAC-DR has poorer bias removal in crowded fields and defaults to larger mosaics. ORAC-DR runs a few times slower than ECLIPSE, but its recipe development is measured in weeks, not years.

Treatment of human autoimmune diseases such as multiple sclerosis (MS) will likely require agents that can prevent or reverse the inflammatory process that results in clinical relapses and disease progression. We evaluated the ability of a newly designed monomeric recombinant TCR ligand (RTL342M) containing HLA-DR2 peptide-binding domains covalently linked to MOG-35-55 peptide to prevent and treat both the initial episode and subsequent relapses of experimental autoimmune encephalomyelitis (EAE) in HLA-DR2 transgenic mice. Single doses of RTL342M given either i.v. or s.c. to HLA-DR2 mice produced a rapid (within 24 h) and dose-dependent reversal of clinical signs of paralytic EAE, and even a single dose < or = 2 microg could produce a significant treatment effect. Multiple daily doses were even more effective than the same total amount of RTL given as a single dose. By establishing the minimal effective dose, we determined that RTLs may be 50 times more potent than molar equivalent doses of myelin peptide alone. RTL342M given prior to induction of EAE prevented disease in most mice, and the remainder could be successfully retreated with RTL. Most important for clinical application, RTL342M was highly effective for treating EAE relapses when given periodically prior to the relapse or even after relapses had occurred. These data demonstrate the rapid and potent clinical effects of RTL342M at disease onset and during relapses in EAE and establish important principles governing the application of this novel approach as a possible therapy for patients with MS.

The Dr-nanos gene is essential for germ cell specification in the planarian Dugesia ryukyuensis.

2012-01-01

Homologs of nanos are required for the formation and maintenance of germline stem cell (GSC) systems and for gametogenesis in many metazoans. Planarians can change their reproductive mode seasonally, alternating between asexual and sexual reproduction; they develop and maintain their somatic stem cells (SSCs) and GCSs from pluripotent stem cells known as neoblasts. We isolated a nanos homolog, Dr-nanos, from the expressed sequence tags (ESTs) of the sexualized form of Dugesia ryukyuensis. We examined the expression of Dr-nanos in asexual and sexualized planarians by in situ hybridization and analyzed its function using RNA interference (RNAi) together with a planarian sexualization assay. A nanos homolog, Dr-nanos, was identified in the planarian D. ryukyuensis. Dr-nanos expression was observed in the ovarian primordial cells of the asexual worms. This expression increased in proportion to sexualization and was localized in the early germline cells of the ovaries and testes. In X-ray-irradiated worms, the expression of Dr-nanos decreased to a large extent, indicating that Dr-nanos is expressed in some subpopulations of stem cells, especially in GSCs. During the sexualization process, worms in which Dr-nanos was knocked down by RNAi exhibited decreased numbers of oogonia in the ovaries and failed to develop testes, whereas the somatic sexual organs were not affected. We conclude that Dr-nanos is essential for the development of germ cells in the ovaries and testes and may have a function in the early stages of germ cell specification, but not in the development of somatic sexual organs.

2018-01-01

This study aims to analyze the relationship between CO concentration and wind direction. Wind direction in this context is the wind angle to the road on the traffic flow in Padang City. Sampling of CO concentration was conducted for 9 days at 3 monitoring points (each 3-day point) representing the wind angle to the road (a) i.e. at Jend. A. Yani road (0 degrees), Andalas road (30 degrees) and Prof. Dr. Hamka road (60 degrees), using impinger and analyzed by spectrophotometer. The results of the research in the three monitoring sites showed that the concentration of CO ranged between 137.217 and 600.525 μg/Nm3. The highest and lowest concentrations respectively on Prof. Dr. Hamka road and Jend. A. Yani road. The sampling showed that CO concentrations will be decreased if wind direction is changed from perpendicular wind direction (a 90°) to a 60°, 30°, and 0° respectively by 64.62%, 37.77% and 27.09%. It can be concluded that the wind angle direction to the road affects the CO concentrations in the roadside.

Résultats Pour les sujets drépanocytaires, la vitesse moyenne (VM) de l'artère cérébrale moyenne était de 100,9 ± 26,8 cm/s, l'indice de pulsatilité (IP) de 0,73 ± 0,20, la différence entre les artères cérébrales moyennes droite et gauche (ACMr) de 19,8 ± 21,5 cm/s, le rapport des vitesses de l'artère cérébrale antérieure/artère cérébrale moyenne (ACA/ACM) de 0,7 ± 0,2. Pour les enfants non drépanocytaires, VM: 80,6 ± 19,3 cm/s, IP: 0,79 ± 0,14, ACMr: 17 ± 20,1 cm/s, ACA/ACM: 0,8 ± 0,2. La vélocité des enfants drépanocytaires était supérieure au groupe contrôle. Les vitesses ont été corrélées avec le taux d'hémoglobine et l’âge et non pas avec le sexe et le volume globulaire moyen. Conclusion Les vitesses circulatoires cérébrales sont élevées chez les drépanocytaires que les enfants non drépanocytaires et sont influencées par le taux d'hémoglobine et l’âge. PMID:27516829

PREFACE: Eighth International Conference on Dissociative Recombination (DR2010)

In dissociative recombination (DR), a molecular ion captures an electron and falls apart. One might initially conclude that this process is relatively simple. However, a review of the DR literature over the past 60 years, since the pioneering papers of Sir David Bates [1], shows that the study of DR has proved to be highly challenging for both theorists and experimentalists. Both this challenge and the ubiquitous importance of the process have made its study rewarding, endlessly interesting, and full of surprises. DR is fundamentally the interaction of an electronic continuum with a vibrational continuum often connected by quasibound intermediate states. Autoionization in the first continuum competes with dissociation in the second. DR occurs at the total energy of an ion plus a free electron and is in the same region as vibrationally excited Rydberg states and other neutral superexcited states. All these states interact with each other prior to dissociation, forming a complex that controls the quantum yields of products. The complexity of the process has required both innovation and ingenuity on the part of both theorists and experimentalists. Over the years, it has become apparent that in order to compare theoretical and experimental results, the experiments must identify the electronic, vibrational and for low mass ions, the rotational state. The traditional disagreement between theoretical and experimental results has been due, in part, to the sensitivity of DR cross sections and rate constants to the state of the recombining ion. Great progress has been made in recent years in both flowing afterglow and storage ring experiments aimed at reducing this uncertainty. The latest advances and insights in theory and experiment were the topics of the Eighth International Conference on Dissociative Recombination held at the Granlibakken Lodge at Lake, Tahoe, California, 16-20 August 2010. The conference was part of a series of conferences on DR that started at Chateau

We present the data release (DR) 5 catalogue of white dwarf-main sequence (WDMS) binaries from the Large sky Area Multi-Object fibre Spectroscopic Telescope (LAMOST). The catalogue contains 876 WDMS binaries, of which 757 are additions to our previous LAMOST DR1 sample and 357 are systems that have not been published before. We also describe a LAMOST-dedicated survey that aims at obtaining spectra of photometrically selected WDMS binaries from the Sloan Digital Sky Survey (SDSS) that are expected to contain cool white dwarfs and/or early-type M dwarf companions. This is a population under-represented in previous SDSS WDMS binary catalogues. We determine the stellar parameters (white dwarf effective temperatures, surface gravities and masses, and M dwarf spectral types) of the LAMOST DR5 WDMS binaries and make use of the parameter distributions to analyse the properties of the sample. We find that, despite our efforts, systems containing cool white dwarfs remain under-represented. Moreover, we make use of LAMOST DR5 and SDSS DR14 (when available) spectra to measure the Na I λλ 8183.27, 8194.81 absorption doublet and/or Hα emission radial velocities of our systems. This allows identifying 128 binaries displaying significant radial velocity variations, 76 of which are new. Finally, we cross-match our catalogue with the Catalina Surveys and identify 57 systems displaying light-curve variations. These include 16 eclipsing systems, two of which are new, and nine binaries that are new eclipsing candidates. We calculate periodograms from the photometric data and measure (estimate) the orbital periods of 30 (15) WDMS binaries.

The authors assessed an expansion of Vermont's Dr. Dynasaur program that would cover all residents age 25 and younger. The current Dr. Dynasaur program combines Vermont's Medicaid program and Child Health Insurance Program for children ages 0 through 18 to provide a seamless insurance program for those with family incomes below 317 percent of the federal poverty level. The authors used RAND's COMPARE-VT microsimulation model with Vermont-specific demographic, economic, and actuarial data to estimate the effects on health insurance coverage, costs, and premiums. They also identified the new revenues required to fund the program expansion and explored three alternative financing strategies to raise those funds: (1) an increase in the Vermont income tax, (2) a Vermont payroll tax, and (3) a Vermont business enterprise tax. The authors found that enrollment would increase by more than 260 percent under the 100-percent enrollment scenario and by nearly 200 percent under the 70-percent enrollment scenario by 2019. Not surprisingly, the children and young adults who move off employer-sponsored insurance (ESI) and into Dr. Dynasaur 2.0 have considerably lower expected health care costs than those who remain on ESI, increasing the per-person premiums by nearly $1,000 for those remaining enrolled in ESI. Annual health care expenditures per person for children and young adults in 2019 are estimated at $4,325 with Medicare prices. The combination of increased reimbursement rates, large increases in enrollment, and relatively low Dr. Dynasaur premiums (no more than $720 per year) will require significant new tax revenues to meet program obligations.

After the creation of the Academy of Medical Sciences of Ukraine in 1993 the Research Center for Radiation Medicine was among the first institutions to join the Academy (fig. 1). Estab lishing the Academy was among the first steps of the independent Ukrainian government and aimed to provide a high level health care for population. It was extremely needed for the minimization of Chornobyl medical consequences. This choice was related to a growing recognition of the scientific research in fulfilling the Сenter's mission - study of the effects of low dose radiation on human body and radiation protection of the exposed population.The Center entered the Academy as a potent insti tution. Director General Dr. Anatoly Romanenko and his first deputy prof.

Dr. William O. Coffee was an ophthalmologist who conducted an office and mail-order practice in the Midwest from the 1880s until 1927. His main stock in trade was a self-discovered absorption cure for a variety of ocular diseases, with particular emphasis on the medical cure of cataracts. Dr. Coffee's career was a checkered one, marked by dubious credentials, exuberant self-promotion, unlikely and exaggerated claims of medical successes, plagiarism, and rejection by the medical "establishment." Certain parallels may be drawn between his activities and some currently observed practices in ophthalmology.

We combined chemo- and immunotherapies by constructing dual therapeutic function immuno-nanoparticles (NPs) consisting of death receptor 5 monoclonal antibody (DR5 mAb)-conjugated nanoparticles loaded with dacarbazine (DTIC) (DTIC-NPs-DR5 mAb). We determined the in vivo targeting specificity of DTIC-NPs-DR5 mAb by evaluating distribution in tumor-bearing nude mice using a real-time imaging system. Therapeutic efficacy was assessed in terms of its effect on tumor volume, survival time, histomorphology, microvessel density (MVD), and apoptotic index (AI). Systemic toxicity was evaluated by measuring white blood cells (WBC) counts, alanine aminotransferase (ALT) levels, and creatinine clearance (CR).In vivo and ex vivo imaging indicates that DR5 mAb modification enhanced the accumulation of NPs within the xenograft tumor. DTIC-NPs-DR5 mAb inhibited tumor growth more effectively than DTIC or DR5 mAb alone, indicating that combining DTIC and DR5 mAb through pharmaceutical engineering achieves a better therapeutic effect. Moreover, the toxicity of DTIC-NPs-DR5 mAb was much lower than that of DTIC, implying that DR5 mAb targeting reduces nonspecific uptake of DTIC into normal tissue and thus decreases toxic side effects. These results demonstrate that DTIC-NPs-DR5 mAb is a safe and effective nanoparticle formulation with the potential to improve the efficacy and specificity of melanoma treatment.

Objective To prepare monoclonal antibodies against DR region (897DVEDSYGQQWTYEQR911) of Na + -K + -ATPase α1 subunit and identify their properties. Methods BALB/c mice were immunized with DR-keyholelimpet hemocyanin (KLH). Splenocytes from the immunized mice were collected and subsequently fused with SP2/0 mouse myeloma cells. Positive hybridoma clones were obtained after cell fusion and selection. ELISA was used to detect DR antibody titer in the cell supernatants. DR region-specific monoclonal antibodies were analyzed by dot blotting, Western blotting and immunofluorescence assay. Na + -K + -ATPase activity was detected by SensoLyte R FDP Protein Phosphatase Assay Kit and the protective effect of the monoclonal antibody against high glucose-induced cell injury was assessed in H9c2 cells. Results Three hybridoma cell lines which secreted stable DR monoclonal antibody were obtained. The strongest positive cell line, named DRm217, was selected to prepare ascites. Dot blotting, Western blotting and immunofluorescence assay showed that DRm217 recognized specially DR region of Na + -K + -ATPase and bound on H9c2 cell membranes. DRm217 stimulated Na + -K + -ATPase activity and alleviated high glucose-induced H9c2 cells injury. Conclusion The monoclonal antibodies against DR region of Na + -K + -ATPase α1 subunit is prepared.

Plasma Exosomes Contribute to Microvascular Damage in Diabetic Retinopathy (DR) by Activating Classical Complement Pathway.

Diabetic Retinopathy (DR) is a micro-vascular complication of diabetes and is the leading cause of vision loss in working-age adults. Recent studies have implicated the complement system as an emerging player in development of vascular damage and progression of DR. However, the role and activation of the complement system in DR is not well understood. Exosomes, small vesicles that are secreted into the extracellular environment, have a cargo of complement proteins in plasma suggesting that they can participate in causing vascular damage associated with DR. We demonstrate that IgG-laden exosomes in plasma activate the classical complement pathway, and that the quantity of these exosomes is increased in diabetes. Moreover, we show that lack of IgG in exosomes results in a reduction of retinal vascular damage in diabetic mice. Together, the results of this study demonstrate that complement activation by IgG-laden plasma exosomes could contribute to the development of DR. © 2018 by the American Diabetes Association.

Gastric cancer tumor markers, such as carcinoembryonic antigen (CEA) and cancer antigen 19-9 (CA 19-9), have been applied in clinical practice to screen or monitor treatment responses. However, their sensitivity and specificity are unsatisfactory. Therefore, we assessed the novel tumor marker DR-70 and evaluated its performance in screening and response monitoring. The study included newly diagnosed patients with advanced gastric cancer from March 2012 to October 2015. We measured the DR-70, CEA, and CA 19-9 levels at the time of enrollment. The patients subsequently underwent chemotherapy. We followed-up the patients every 3 months; DR-70 levels and abdominal computed tomography scans were re-evaluated and repeated, respectively, at each follow-up. The correlation between treatment response and DR-70 level after chemotherapy was analyzed. The overall survival and progression-free survival rates were also evaluated. A total of 51 patients with gastric cancer were enrolled. Most (82.4%) had metastatic disease. At enrollment, the sensitivity of DR-70 in our study group was 78.4%, compared with 52.9% and 43.1% for CEA and CA 19-9, respectively. When we used the three tumor markers together, the sensitivity increased to 80.4%. We observed a correlation between treatment response and DR-70 level after chemotherapy. No difference in either overall survival or progression-free survival was observed between the DR-70 positive and negative groups. However, a trend toward poorer overall survival was observed for the high DR-70 group, although this was not statistically significant. DR-70 is a powerful tool not only for screening unresectable gastric cancer but also for treatment response evaluation. Copyright © 2018. Published by Elsevier Taiwan LLC.

The major susceptibility locus for type 1 diabetes mellitus (T1D) maps to the human lymphocyte antigen (HLA) class II region in the major histocompatibility complex on chromosome 6p21. In southern European populations, like the Basques, the greatest risk to T1D is associated with DR3 homo- and heterozygosity and is comparable to that of DR3/DR4, the highest risk genotype in northern European populations. Celiac disease (CD) is another DR3-associated autoimmune disorder showing certain overlap with T1D that has been explained by the involvement of common genetic determinants, a situation more frequent in DR3-rich populations, like the Basques. As both T1D- and CD-associated HLA alleles are part of conserved extended haplotypes (CEH), we compared DR3-homozygous T1D and CD patients to determine whether CEHs were equally distributed between both disorders or there was a differential contribution of different haplotypes. We observed a very pronounced distribution bias (P<10(-5)) of the two major DR3 CEHs, with DR3-B18 predominating in T1D and DR3-B8 in CD. Additionally, high-density single nucleotide polymorphism (SNP) analysis of the complete CEH [A*30-B*18-MICA*4-F1C30-DRB1*0301-DQB1*0201-DPB1*0202] revealed extraordinary conservation throughout the 4.9 Mbp analyzed supporting the existence of additional diabetogenic variants (other than HLA-DRB1*0301-DQB1*0201), conserved within the DR3-B18 CEH (but not in other DR3 haplotypes) that could explain its enhanced diabetogenicity.

DR3 regulation of apoptosis of naive T-lymphocytes in children with acute infectious mononucleosis.

Acute infectious mononucleosis (AIM) is a widespread viral disease that mostly affects children. Development of AIM is accompanied by a change in the ratio of immune cells. This is provided by means of different biological processes including the regulation of apoptosis of naive T-cells. One of the potential regulators of apoptosis of T-lymphocytes is a death receptor 3 (DR3). We have studied the role of DR3 in the regulation of apoptosis of naive CD4 + (nTh) and CD8 + (nCTL) T-cells in healthy children and children with AIM. In healthy children as well as in children with AIM, the activation of DR3 is accompanied by inhibition of apoptosis of nTh. In healthy children, the stimulation of DR3 resulted in the increase in apoptosis of nCTL. On the contrary, in children with AIM, the level of apoptosis of nCTL decreased after DR3 activation, which is a positive contribution to the antiviral immune response. In children with AIM, nCTL are characterized by reduced level of apoptosis as compared with healthy children. These results indicate that DR3 can be involved in the reduction of sensitivity of nCTL to apoptosis in children with AIM.

Transdermal drug delivery continues to provide an advantageous route of drug administration over injections. While the number of drugs delivered by passive transdermal patches has increased over the years, no macromolecule is currently delivered by the transdermal route. Substantial research efforts have been dedicated by a large number of researchers representing varied disciplines including biology, chemistry, pharmaceutics and engineering to understand, model and overcome the skin's barrier properties. This article focuses on engineering contributions to the field of transdermal drug delivery. The article pays tribute to Prof. Robert Langer, who pioneered the engineering approach towards transdermal drug delivery. Over a period spanning nearly 25 years since his first publication in the field of transdermal drug delivery, Bob Langer has deeply impacted the field by quantitative analysis and innovative engineering. At the same time, he has inspired several generations of engineers by collaborations and mentorship. His scientific insights, innovative technologies, translational efforts and dedicated mentorship have transformed the field. © 2013 S. Karger AG, Basel.

GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) is a European Commission (EC)-funded project, kicked-off early 2008 lead by ESA; partners include Space Agencies (DLR, ASI, CNES), both space and no-space data providers such as ENEA (I), Infoterra (UK), K-SAT (N), NILU (N), JRC (EU) and industry as Elsag Datamat (I), CS (F) and TERRADUE (I). GENESI-DR intends to meet the challenge of facilitating "time to science" from different Earth Science disciplines in discovery, access and use (combining, integrating, processing, …) of historical and recent Earth-related data from space, airborne and in-situ sensors, which are archived in large distributed repositories. In fact, a common dedicated infrastructure such as the GENESI-DR one permits the Earth Science communities to derive objective information and to share knowledge in all environmental sensitive domains over a continuum of time and a variety of geographical scales so addressing urgent challenges such as Global Change. GENESI-DR federates data, information and knowledge for the management of our fragile planet in line with one of the major goals of the many international environmental programmes such as GMES, GEO/GEOSS. As of today, 12 different Digital Repositories hosting more than 60 heterogeneous dataset series are federated in GENESI-DR. Series include satellite data, in situ data, images acquired by airborne sensors, digital elevation models and model outputs. ESA has started providing access to: Category-1 data systematically available on Internet; level 3 data (e.g., GlobCover map, MERIS Global Vegetation Index); ASAR products available in ESA Virtual Archive and related to the Supersites initiatives. In all cases, existing data policies and security constraints are fully respected. GENESI-DR also gives access to Grid and Cloud computing resources allowing authorized users to run a number of different processing services on the available data. The GENESI-DR

This paper will review Winston Churchill's severe respiratory illness in March 1886 when he developed pneumonia of the right lung as an 11-year-old boy. Winston was treated supportively with 'nourishment, stimulants [probably alcohol] and close watching' at his school by the 'celebrated' family physician, Dr Robson Roose, with the assistance of Dr Joseph Rutter. Roose was exemplary in his commitment to his young patient and assiduous in informing Lord Randolph Churchill of his son's clinical progress by letter.

The paucity of regulatory T cells (Tregs) limits clinical translation to control aberrant immune reactions including graft-versus-host disease (GVHD). Recent studies showed that the agonistic antibody to DR3 (αDR3) expanded CD4+FoxP3+ Tregs in vivo. We investigated whether treating donor mice with a single dose of αDR3 could alleviate acute GVHD in a MHC-mismatched bone marrow transplantation model. αDR3 induced selective proliferation of functional Tregs. CD4+ T cells isolated from αDR3-treated mice contained higher numbers of Tregs and were less proliferative to allogeneic stimuli. In vivo GVHD studies confirmed that Tregs from αDR3-treated donors expanded robustly and higher frequencies of Tregs within donor CD4+ T cells were maintained, resulting in improved survival. Conventional T cells derived from αDR3-treated donors showed reduced activation and proliferation. Serum levels of proinflammatory cytokines (IFNγ, IL-1β, and TNFα) and infiltration of donor T cells into GVHD target tissues (gastrointestinal tract and liver) were decreased. T cells from αDR3-treated donors retained graft-vs-tumor (GVT) effects. In conclusion, a single dose of αDR3 alleviates acute GVHD while preserving GVT effects by selectively expanding and maintaining donor Tregs. This novel strategy will facilitate the clinical application of Treg-based therapies. PMID:26063163

This report describes the evaluation of the novel MTB-DR-RIF 9G test for the accurate detection and discrimination of Mycobacterium tuberculosis (MTB) and rifampicin-resistant M. tuberculosis (MTB-DR-RIF) in the clinical samples. The procedure included the amplification of a nucleotide fragment of the rpoB gene of the MTB and MTB-DR-RIF strains and their hybridization with the immobilized probes. The MTB-DR-RIF 9G test was evaluated for its ability to detect and discriminate MTB and MTB-DR-RIF strains in 113 known clinical samples. The accuracy of the MTB-DR-RIF 9G test was determined by comparing its results with sequencing analysis and drug susceptibility testing. The sensitivity and specificity of the MTB-DR-RIF 9G test at 95% confidence interval were found to be 95.4% (89.5-98.5) and 100% (69.2-100), respectively. The positive predictive value and negative predictive value of the MTB-DR-RIF 9G test at 95% confidence interval were found to be 100% (85.0-95.9) and 66.7% (38.4-88.18), respectively. Sequencing analysis of all samples indicated that the mutations present in the regions identified with the MTB-DR-RIF 9G assay can be detected accurately. Copyright © 2015 Elsevier Ltd.

S69-39588 (20 July 1969) --- Dr. Garry Latham, with the Lamont Geological Observatory, studies seismometer tracings in the Mission Control Center?s ASEP control room. The electronic data was coming from the Passive Seismic Experiments Package which the Apollo 11 astronauts had just deployed on the surface of the moon. Dr. Lamont is the principal investigator for the PSEP, a component of the Early Apollo Scientific Experiments Package (EASEP). PSEP uses three long-period seismometers and one short-period vertical seismometer for measuring meteoroid impacts and moonquakes. Such data will be useful in determining the interior structure of the moon; for example, does the moon have a core and mantle like Earth? Here, the center trace shows evidence of activity on the moon. The PSEP was sensitive enough to pick up the footsteps of astronauts Neil A. Armstrong and Edwin E. Aldrin Jr. as they walked on the moon.

On 4.8.1911 Dr. Moshe Sherman landed at the port of Jaffa. He was the first otolaryngologist in Eretz-Israel and for one year he was the only specialist in the country. Dr. Sherman was born in Nikolayev (Russia) in 1881. He started his medical education in Odessa, continued in Berlin, graduated in 1907 at the University of Dorpat (Estonia) and pursued postgraduate studies in otolaryngology at Moscow University. He settled in Jaffa, started a private practice and soon became a famous specialist. He volunteered at the Jewish hospital in Jaffa--"Shaar Zion", and twice a year spent several weeks in Jerusalem seeing patients and performing small operations. On January 1912 Dr. Sherman, together with another 5 physicians, laid the foundations for the first doctors' organization in Israel: "The Medical Society of Jaffa and Jaffa district". In 1918 Dr. Sherman was elected consultant at the Hadassah Hospital in Tel Aviv, and in 1932 a department for ear, nose and throat diseases was established there under his management. He was the founder and first chairman of the Ototaryngology Society in Eretz-Israel, and in 1935 was elected the chairman of the Jewish Medical Association in Eretz-Israel (later--its honorary president). He was the initiator and founder of the "World Fellowship", and the Editor in Chief of 'Harefuah' and "Michtav Lachaver". Dr. Sherman was the author of numerous papers related to his specialty and to the history of Jewish organizations in Eretz-Israel and, later, in the State of Israel. Dr. Sherman died in Tel Aviv on July 17th 1969.

To test whether HLA-DR4 acts in the mother, possibly during pregnancy, to contribute to the phenotype of autistic disorder in her fetus. Transmission disequilibrium testing in case mothers and maternal grandparents. Previous studies have consistently shown increased frequency of HLA-DR4 in probands with autism and their mothers, but not their fathers. However, this has been documented only in case-control studies and not by a more direct study design to determine whether HLA-DR4 acts in mothers during pregnancy to contribute to autism in their affected offspring. We genotyped for HLA-DR alleles in members of 31 families with parents and maternal grandparents. Probands with autism were tested using the Autism Diagnostic Observation Schedule-Western Psychological Services and Autism Diagnostic Interview, Revised. There was 80% power to detect an odds ratio of 3.6. Participants were all families from New Jersey and were similar in number to earlier studies of autism and HLA-DR4. Analysis was by standard transmission disequilibrium testing. As a secondary test we examined the possibility of maternal imprinting. Significant transmission disequilibrium for HLA-DR4 was seen (odds ratio, 4.67; 95% confidence interval, 1.34-16.24; P = .008) for transmissions from maternal grandparents to mothers of probands, supporting a role for HLA-DR4 as an autism risk factor acting in mothers during pregnancy. Transmission disequilibrium was not seen for HLA-DR4 transmissions from parents to probands or from mothers to probands. The HLA-DR4 gene may act in mothers of children with autism during pregnancy to contribute to autism in their offspring. Further studies are required to confirm these findings.

Objective: To find an association between human leukocyte antigen (HLA) class II DRB1, DRB3, DRB4, and DRB5 alleles frequencies in a sample of Iraqi patients with Guillain-Barré syndrome (GBS) and compare with a healthy control group. Methods: We performed a cross-sectional study consisting of 30 Iraqi Arab patients with GBS attending the Neurological Department in the Neuroscience Hospital, Baghdad, Iraq between September 2012 and June 2013. The control group comprised 42 apparently healthy volunteers. Human leukocyte antigen genotyping for HLA DRB1, DRB3, DRB4, and DRB5 was performed using the polymerase chain reaction-sequence-specific primers method. The allele frequencies were compared across both groups. Major histocompatibility complex (MHC)-class II HLA-DR genotyping and serotyping were performed by software analysis. Results: We found increased frequencies of HLA genotype DRB1*03:01 (p=0.0009), DRB1*07:01 (p=0.0015), and DRB4*01:01 (p<0.0001) in patients with GBS compared with healthy controls. The HLA DR6 was increased in the control group (p<0.0001). Conclusions: Our results suggest an association between HLA-DRB1*03:01, DRB1*07:01, DRB4*01:01, and HLA DR3, DR7 and a susceptibility to GBS. PMID:25274590

A total of 72 sporadic colorectal adenomas in 56 patients were studied for the presence of point mutations in codons 12 and 13 of the K-ras gene and for HLA-DR antigen expression related to clinicopathological variables. Forty K-ras mutations in 39 adenomas were found (54%): 31 (77%) in codon 12 and nine (23%) in codon 13. There was a strong relationship between the incidence of K-ras mutations and adenoma type, degree of dysplasia and sex. The highest frequency of K-ras mutations was seen in large adenomas of the villous type with high-grade dysplasia. Fourteen out of 15 adenomas obtained from 14 women above 65 years of age carried mutations. HLA-DR positivity was found in 38% of the adenomas, large tumours and those with high-grade dysplasia having the strongest staining. Coexpression of K-ras mutations and HLA-DR was found significantly more frequently in large and highly dysplastic adenomas, although two-way analysis of variance showing size and grade of dysplasia to be the most important variable. None of the adenomas with low-grade dysplasia showed both K-ras mutation and HLA-DR positivity (P = 0.004). K-ras mutation is recognised as an early event in colorectal carcinogenesis. The mutation might give rise to peptides that may be presented on the tumour cell surface by class II molecules, and thereby induce immune responses against neoplastic cells.

Objective Certain human leukocyte antigen (HLA)-DR,DQ genotypes have been associated with type 1 diabetes mellitus (T1DM) risk, although it is unknown whether the association is due to alleles, haplotypes, genotypes, the formation of heterodimers, or all of the above. To characterize the role of the HLA-DR,DQ genotype and ethnicity on the onset age of T1DM, we analyzed these factors in patients with T1DM and the general population. Methods One thousand three hundred twenty-two well-characterized patients with T1DM were compared with 3339 children from the general population of Denver, Colorado, USA. Because of the extensive available data across age and ethnic groups, this study population is unique. Results The HLA-DR3/4,DQB1*0302, DRX/4,DQB1*0302 (where X = 1, 4, 8, and 9), and HLA-DR3/3 genotypes were associated with T1DM, supporting previous research. Additionally, the DR3/9 genotype showed a positive association with T1DM, which has not previously been described in Caucasian populations. The HLA-DR3/4*0302 genotype was most strongly associated with T1DM in diabetic individuals with the youngest onset age. Genotype frequencies were similar between Hispanics and non-Hispanic whites, except for the DR3/3 genotype, which was more likely to be found in non-Hispanic whites. Conclusions These results indicate that there are multiple alleles and genotypes associated with T1DM and that the risk associated with different genetic markers depends on the age of disease onset, suggesting that some markers may be involved in more rapid disease progression.

To analyze the polymorphism of HLA-A, B and DR alleles of Duchenne muscular dystrophy (DMD) patients in Han nationality of South China and to discuss the role of immune and genetic factors in the pathogenesis of DMD and muscular fiber necrosis. Polymerase chain reaction-reverse sequence specific oligonucleotide (PCR-RSSO) and National Marrow Donor Program (NMDP) were used to analyze the polymorphism of HLA-A,B and DR alleles of 113 DMD patients and 406 normal controls in Han nationality of South China. The frequencies of HLA-A24, A30 alleles in DMD group were 11.25% and 5.46% respectively, indicating notable difference (P=0.001, < 0.01) from 22.16% and 0.87% of control group; the frequencies of HLA-B13, B15, B61 and B62 alleles in DMD group were 12.26%, 16.92%, 0.44% and 0.44%, indicating a notable difference (P=0.016, < 0.01, 0.001) from 6.76%, 1.49%, 4.79% and 5.05% of control group; the frequencies of HLA-DR04, DR07, DR12 alleles in DMD group were 17.45%, 6.40% and 19.62%, indicating a notable difference (P=0.018, < 0.01, 0.012) from 10.67%, 2.24% and 11.92% of control group. There are significant differences in the HLA gene frequencies between DMD patients and normal controls. These results suggest that HLA genotype relates to the muscular necrosis and the pathogenesis of DMD.

In 1826, Dr John McLennan was asked by Governor Mounstuart Elphinstone of Bombay to set up the first school to teach modern medicine to Indian citizens. He was expected to create textbooks on a variety of subjects in local languages and teach medicine to poorly educated students in their native tongues. Despite his valiant efforts, the school was deemed a failure and was abolished by the Government in 1832. Sir Robert Grant, appointed Governor of Bombay in 1835, analysed records pertaining to this medical school and concluded that the school failed since Dr McLennan was not provided the assistance he needed and as his suggestions for access to a hospital to teach medicine were not heeded. Dr McLennan provided able support to Dr Charles Morehead on his appointment as Principal and Professor of Medicine at the newly created Grant Medical College in Bombay in 1845. Dr Morehead dedicated his classic 'Clinical researches on diseases in India' to Dr McLennan. Dr McLennan headed the Board of Examiners created to assess the competence of the first batch of medical students emerging from this College. The system of evaluation set up by him remains admirable. Dr McLennan retired from service as Physician-General, full of honours.

The introduction of human leukocyte antigen (HLA)-matching in nonliving kidney transplantation has resulted into a better graft outcome, but also in an increase of waiting time, especially for patients with rare HLA phenotypes. We addressed the question of the differential influence of HLA-DR-matching versus HLA-A,B in clinical kidney transplantation. We used Kaplan-Meier product limit method to estimate survival rates, and Cox proportional hazard regression for the estimation of relative risks (Hazard-ratios) for different variables. A single center study (n=456 transplants, performed between 1985 and 1999) showed that full HLA-DR compatibility leads to a lower incidence of biopsy confirmed acute rejections in the first 180 posttransplantation days. These results were substantiated using the Eurotransplant database (n=39,205 transplants performed between 1985 and 2005) where graft survival in the full HLA-DR compatible group was significantly better than in the incompatible. An additional positive effect of HLA-A,B matching was only found in the full HLA-DR compatible group. In both studies, the introduction of a single HLA-DR incompatibility eliminates the HLA-A,B matching effect. We propose to allocate postmortem kidneys only to patients with full HLA-DR compatibility, and use HLA-A,B compatibility as an additional selection criterion. All patients, irrespective of their ethnic origin, will profit since the polymorphism of HLA-DR is by far lower than that of HLA-A,B. Excessive kidney travel and cold ischemia time will be significantly reduced.

Because of rod-sticking problems at DR Reactor, a knuckle rod of B Reactor design was installed in vertical safety channel number 28. The substitute VSR, which has a smaller diameter than the original DR rod, has been tested for its operational feasibility including both drop time and reactivity effect. The reactivity effect of the rod was estimated by comparison of the reactivity transient caused by insertion of the specific B-type rod after scramming into the pile, with similar transients caused by normal vertical safety rod in an adjacent channel. This document lists the indicated relative control strength of the rodmore » as an empirical basis for future safety calculations. Results indicate that the B-type knuckel rod in DR reactor is about 80% as strong as a normal DR vertical safety rod if used in equivalent flux distribution and location; this makes it reasonable to assume that the local control strength of the B-type knuckel rod is 98 {mu}b.« less

Reports have shown that activation of tumor-specific CD4+ helper T (Th) cells is crucial for effective anti-tumor immunity and identification of Th-cell epitopes is critical for peptide vaccine-based cancer immunotherapy. Although computer algorithms are available to predict peptides with high binding affinity to a specific HLA class II molecule, the ability of those peptides to induce Th-cell responses must be evaluated. We have established HLA-DR4 (HLA-DRA*01:01/HLA-DRB1*04:05) transgenic mice (Tgm), since this HLA-DR allele is most frequent (13.6%) in Japanese population, to evaluate HLA-DR4-restricted Th-cell responses to tumor-associated antigen (TAA)-derived peptides predicted to bind to HLA-DR4. To avoid weak binding between mouse CD4 and HLA-DR4, Tgm were designed to express chimeric HLA-DR4/I-Ed, where I-Ed α1 and β1 domains were replaced with those from HLA-DR4.

Immunization with CDCA155-78 peptide, a computer algorithm-predicted HLA-DR4-binding peptide derived from TAA CDCA1, successfully induced Th-cell responses in Tgm, while immunization of HLA-DR4-binding Wilms' tumor 1 antigen-derived peptide with identical amino acid sequence to mouse ortholog failed. This was overcome by using peptide-pulsed syngeneic bone marrow-derived dendritic cells (BM-DC) followed by immunization with peptide/CFA booster. BM-DC-based immunization of KIF20A494-517 peptide from another TAA KIF20A, with an almost identical HLA-binding core amino acid sequence to mouse ortholog, successfully induced Th-cell responses in Tgm. Notably, both CDCA155-78 and KIF20A494-517 peptides induced human Th-cell responses in PBMCs from HLA-DR4-positive donors. Finally, an HLA-DR4 binding DEPDC1191-213 peptide from a new

Dr. Hulusi Behçet was born on February 20, 1889 in Istanbul. He graduated from Gülhane Military Medical Academy in 1910 and then he specialized in Dermatology and Venereal Diseases. He served in the Edirne Military Hospital between 1914-1918 and then went to Budapest and Berlin to improve his knowledge. In 1923, he started at the Istanbul Medical Faculty as an academic staff and with university reform in 1933, he was appointed as a professor to Department of Dermatology and Venereal Diseases and continued his career there until his death in 1948. Three patients whom he had consulted for years and who shared similar symptoms made him suspect a new disease and a viral etiology which may play a role in the appearance of this disease. After several discussions and publications, medical literature had accepted Behçet's Disease as a special entity. Dr. Behçet published a total of 196 articles, 53 of which were published in prestigious international journals.

The roots of modern oncology: from discovery of new antitumor anthracyclines to their clinical use.

In May 1960, the Farmitalia CEO Dr. Bertini and the director of the Istituto Nazionale dei Tumori of Milan Prof. Bucalossi (talent scout and city's Mayor) signed a research agreement for the discovery and development up to clinical trials of new natural antitumor agents. This agreement can be considered as a pioneering and fruitful example of a translational discovery program with relevant transatlantic connections. Owing to an eclectic Streptomyces, found near Castel del Monte (Apulia), and to the skilled and motivated participants of both institutions, a new natural antitumor drug, daunomycin, was ready for clinical trials within 3 years. Patent interference by the Farmitalia French partner was overcome by the good quality of the Italian drug and by the cooperation between Prof. Di Marco, director of the Istituto Ricerche Farmitalia Research Laboratories for Microbiology and Chemotherapy, and Prof. Karnofsky, head of the Sloan-Kettering Cancer Institute of New York, leading to the first transatlantic clinical trials. The search for daunomycin's sister anthracyclines led to the discovery and development of adriamycin, one of the best drugs born in Milan. This was the second act prologue of the history of Italian antitumor discovery and clinical oncology, which started in July 1969 when Prof. Di Marco sent Prof. Bonadonna the first vials of adriamycin (doxorubicin) to be tested in clinical trials. This article reviews the Milan scene in the 1960s, a city admired and noted for the outstanding scientific achievements of its private and public institutions in drugs and industrial product discovery.

Summary Autoimmune hepatitis (AIH) is a chronic liver disease characterized by progressive inflammation, female preponderance and seropositivity for autoantibodies such as anti‐smooth muscle actin and/or anti‐nuclear, anti‐liver kidney microsomal type 1 (anti‐LKM1) and anti‐liver cytosol type 1 (anti‐LC1) in more than 80% of cases. AIH is linked strongly to several major histocompatibility complex (MHC) alleles, including human leucocyte antigen (HLA)‐DR3, ‐DR7 and ‐DR13. HLA‐DR4 has the second strongest association with adult AIH, after HLA‐DR3. We investigated the role of HLA‐DR4 in the development of AIH by immunization of HLA‐DR4 (DR4) transgenic non‐obese diabetic (NOD) mice with DNA coding for human CYP2D6/FTCD fusion autoantigen. Immunization of DR4 mice leads to sustained mild liver injury, as assessed biochemically by elevated alanine aminotransferase, histologically by interface hepatitis, plasma cell infiltration and mild fibrosis and immunologically by the development of anti‐LKM1/anti‐LC1 antibodies. In addition, livers from DR4 mice had fewer regulatory T cells (Tregs), which had decreased programmed death (PD)‐1 expression. Splenic Tregs from these mice also showed impaired inhibitory capacity. Furthermore, DR4 expression enhanced the activation status of CD8+ T cells, macrophages and dendritic cells in naive DR4 mice compared to naive wild‐type (WT) NOD mice. Our results demonstrate that HLA‐DR4 is a susceptibility factor for the development of AIH. Impaired suppressive function of Tregs and reduced PD‐1 expression may result in spontaneous activation of key immune cell subsets, such as antigen‐presenting cells and CD8+ T effectors, facilitating the induction of AIH and persistent liver damage.

There are considerable racial differences in the distribution of HLA-DR2-associated DRB1 and DRB5 alleles and the characteristics of linkage disequilibrium between these alleles. In this study, the frequencies of DR2-associated DRB1 and DRB5 alleles and related haplotypes were analyzed in 186 DR2-positive individuals out of 800 normal Koreans registered for unrelated bone marrow donors. HLA class I antigen typing was performed by the serological method and DRB1 and DRB5 genotyping by the PCR-single strand conformational polymorphism method. Only 3 alleles were detected for DR2-associated DRB1 and DRB5 genes, respectively: DRB1(*)1501 (gene frequency 8.0%), (*)1502 (3.2%), (*)1602 (0.9%); DRB5(*)0101 (8.0%), (*)0102 (3.2%), and (*)0202 (0.9%). DRB1-DRB5 haplotype analysis showed an exclusive association between these alleles: DRB1*1501-DRB5*0101 (haplotype frequency 8.0%), DRB1(*)1502-DRB5(*)0102 (3.2%), and DRB1(*)1602-DRB5(*)0202 (0.9%). The 5 most common DR2-associated A-B-DRB1 haplotypes occurring at frequencies of > or = 0.5% were A24-B52-DRB1(*)1502 (1.8%), A2-B62-DRB1(*)1501, A2-B54-DRB1(*)1501, A26-B61-DRB1(*)1501, and A24-B51-DRB1(*)1501. The remarkable homogeneity in the haplotypic associations between DR2-associated DRB1 and DRB5 alleles in Koreans would be advantageous for organ transplantation compared with other ethnic groups showing considerable heterogeneity in the distribution of DRB1-DRB5 haplotypes.

Frontotemporal dementia (FTD) is a clinical syndrome characterized by progressive decline in social conduct and a focal pattern of frontal and temporal lobe damage. Its biological basis is still poorly understood but the focality of the brain degeneration provides a powerful model to study the cognitive and anatomical basis of social cognition. Here, we present Dr. A, a patient with a rare hereditary bone disease (hereditary multiple exostoses) and FTD (pathologically characterized as Pick’s disease), who presented with a profound behavioral disturbance characterized by acquired sociopathy. We conducted a detailed genetic, pathological, neuroimaging and cognitive study, including a battery of tests designed to investigate Dr. A’s abilities to understand emotional cues and to infer mental states and intentions to others (theory of mind). Dr. A’s genetic profile suggests the possibility that a mutation causing hereditary multiple exostoses, Ext2, may play a role in the pattern of neurodegeneration in frontotemporal dementia since knockout mice deficient in the Ext gene family member, Ext1, show severe CNS defects including loss of olfactory bulbs and abnormally small cerebral cortex. Dr. A showed significant impairment in emotion comprehension, second order theory of mind, attribution of intentions, and empathy despite preserved general cognitive abilities. Voxel-based morphometry on structural MRI images showed significant atrophy in the medial and right orbital frontal and anterior temporal regions with sparing of dorsolateral frontal cortex. This case demonstrates that social and emotional dysfunction in FTD can dissociate from preserved performance on classic executive functioning tasks. The specific pattern of anatomical damage shown by VBM emphasizes the importance of the network including the superior medial frontal gyrus as well as temporal polar areas, in regulation of social cognition and theory of mind. This case provides new evidence regarding the

Dr. Wallach, who founded the Shaare Zedek Hospital and managed the institution for forty-five years, was instrumental in providing modern medical care to Jerusalem residents since his arrival in the city in 1891. He dedicated his life to medicine, to the Jerusalem Jewish community, and to improving the quality of service provided by the existing medical establishment. He was one of the outstanding personalities in a city and community struggling for existence. The Jewish religious character that marks today's Shaare Zedek hospital was determined 100 years ago by Dr. Wallach, who integrated the ancient Jewish moral spirit into a modern medical service tradition. While fulfilling his daily tasks, both as a practicing physician and as the hospital-director, Dr. Wallach became a role model to those who followed him. He mixed freely with the "elite" and his personal relations with local dignitaries, political figures, influential westerners, intellectuals, and important foreign diplomats contributed significantly to the growth, success, and reputation the hospital enjoyed during the last century. On the other hand, he was also personally involved with destitute new immigrants to Eretz Israel and actively engaged in finding jobs, housing, and employment for them. Dr. Wallach became a legend in his own time, both locally and internationally. Due to his professional status and personality, Dr. Wallach became a representative of the Jewish community. He had the ability to speak for the Jews with the Ottoman authorities, and afterwards with the British Mandate authorities. He played a significant role in educating the population in public responsibility, while concurrently leaving his mark on generations of physicians who learned from him the value of precision, loyalty, professional secrecy, and medical responsibility. He was one of the "Giants" of the land (Yishuv) in its critical formative years.

Last year we submitted and had accepted a paper entitled "The Far-Infrared Emission Line and Continuum Spectrum of the Seyfert Galaxy NGC 1068," by Spinoglio, L., Malkan, M., Smith. HA, Gonzalez-Alfonso, E., and Fischer, J. This analysis was based on the SWAS Monte Carlo code modeling of the OH lines in galaxies observed by ISO. Since that meeting last spring considerable effort has been put into improving the Monte Carlo code. A group of European astronomers, including Prof. Eduardo Gonzalez-Alfonso, had been performing Monte Carlo modeling of other molecules seen in ISO galaxies. We used portions of this grant to bring Prof. Gonzalez-Alfonso to Cambridge for an intensive working visit. A second major paper on the ISO IR spectroscopy of galaxies, "The Far Infrared Spectrum of Arp 220," Gonzalez-Alfonso, E., Smith. H., Fischer, J., and Cernicharo, J., is in press. Spitzer science development was the major component of this past year;s research. This program supported the development of five Early Release Objects for Spitzer observations on which Dr. Smith was Principal Investigator or Co-Investigator, and another five proposals for GO time. The early release program is designed to rapidly present to the public and the scientific community some exciting results from Spitzer in the first months of its operation. The Spitzer instrument and science teams submitted proposals for ERO objects, and a competitive selection process narrowed these down to a small group with exciting science and realistic observational parameters. This grant supported Dr. Smith's participation in the ERO process, including developing science goals, identifying key objects for observation, and developing the detailed AOR (observing formulae) to be use by the instruments for mapping, integrating, etc.). During this year Dr. Smith worked on writing up and publishing these early results. The attached bibliography includes six of Dr. Smith's articles. During this past year Dr. Smith also led or

Regarded as "America's first plastic surgeon," Dr John Peter Mettauer's professional life displays 3 fundamental keystones of plastic surgery: education, innovation, and practice. To fully appreciate the history of our plastic surgery, one must look beyond a purely factual recount of noteworthy actions performed decades ago. Fundamental principles that governed achievements of our predecessors remain applicable even today. Dr Mettauer thrived as a medical student under the influence of distinguished professors in medicine at the University of Pennsylvania. Later, he continued to propagate their basic tenets when he established his medical institute in 1837. Throughout his life, Dr Mettauer combined ingenuity with scientific inquiry to devise numerous unprecedented surgical techniques and instruments. He was a prolific writer and exquisitely documented his work in medical journals for the benefit of both contemporary and future surgeons. One of Dr Mettauer's momentous achievements in plastic surgery that displays his remarkable capabilities was his contributions to management of both simple and complicated cases of cleft palate. He was the first to describe relaxing lateral incisions for treating complete cleft palates and, incidentally, was the first to successfully treat this in America. He invariably replicated similar success in establishing techniques for treating a wide range of anatomic deformities. Cumulatively, Dr Mettauer's lifelong commitment and diligence have truly laid a foundation for the eventual progress and success in the field of plastic surgery.

On December 7, 1941, a 60-year old dentist from Irwin, Pennsylvania, Dr. Lytle S. Adams, was driving home from a vacation at Carlsbad Caverns in New Mexico. Hours earlier, he had been gripped with amazement as he witnessed millions of bats exiting the caves of Carlsbad. Listening to his car radio on his return trip, he was shocked to hear that Japan had just attacked Pearl Harbor. Dr. Adams, outraged over this travesty, began to mentally construct a plan for U.S. retaliation. As his thoughts returned to the countless bats that had awed him, he formed a tentative plan: millions of these small, flying mammals could be connected to tiny, time-fused incendiary bombs, and then released to land on the flimsily constructed structures which dotted the cities of Japan. Within a few minutes, the bombs would explode and enflame the entire urban areas. He postulated that these immeasurable numbers of fires, spreading their devastation over such vast areas within Japanese cities would result in the enemy's speedy surrender. This article documents the futile efforts of Dr. Adams, his team and the U.S. government to develop and employ an effective, incendiary bat bomb. The recently developed atom bomb, a far more deadly weapon was used in its place.

2007-03-01

This paper introduces Dr.LiTHO, a research and development oriented lithography simulation environment developed at Fraunhofer IISB to flexibly integrate our simulation models into one coherent platform. We propose a light-weight approach to a lithography simulation environment: The use of a scripting (batch) language as an integration platform. Out of the great variety of different scripting languages, Python proved superior in many ways: It exhibits a good-natured learning-curve, it is efficient, available on virtually any platform, and provides sophisticated integration mechanisms for existing programs. In this paper, we will describe the steps, required to provide Python bindings for existing programs and to finally generate an integrated simulation environment. In addition, we will give a short introduction into selected software design demands associated with the development of such a framework. We will especially focus on testing and (both technical and user-oriented) documentation issues. Dr.LiTHO Python files contain not only all simulation parameter settings but also the simulation flow, providing maximum flexibility. In addition to relatively simple batch jobs, repetitive tasks can be pooled in libraries. And as Python is a full-blown programming language, users can add virtually any functionality, which is especially useful in the scope of simulation studies or optimization tasks, that often require masses of evaluations. Furthermore, we will give a short overview of the numerous existing Python packages. Several examples demonstrate the feasibility and productiveness of integrating Python packages into custom Dr.LiTHO scripts.

A new HLA-DR12 allele has been identified in a European Caucasoid bone marrow donor. The DRB1*12012 allele differs from DRB1*12011 by two silent substitutions at codons 72 and 78, two polymorphic positions used for DNA subtyping of the DR12 serotype. The co-occurence of the two nucleotide changes is unique to the DR12 group and results in a new PCR-SSP typing pattern. The complete HLA type of the donor is A24, A68; B55, B61; Cw*01, Cw*0304; DRB1*12012, DRB1*1402; DRB3*0101, DRB3*0202; DQB1*0301. HLA-DRB1*12012 is a rare allele as it occurs in < 0.2% of DR12 donors.

2017-02-01

Dr. Mehmet Oz is widely known not just as a successful media personality donning the title "America's Doctor ® ," but, we suggest, also as a physician visibly out of step with his profession. A recent, unsuccessful attempt to censure Dr. Oz raises the issue of whether the medical profession can effectively self-regulate at all. It also raises concern that the medical profession's self-regulation might be selectively activated, perhaps only when the subject of professional censure has achieved a level of public visibility. We argue here that the medical profession must look at itself with a healthy dose of self-doubt about whether it has sufficient knowledge of or handle on the less visible Dr. "Ozes" quietly operating under the profession's presumptive endorsement. © 2017 American Medical Association.

Treatment of TRAIL-resistant tumor cells with the nitric oxide donor DETANONOate sensitizes the tumor cells to TRAIL-induced apoptosis concomitantly with DR5 upregulation. The mechanism of sensitization was examined based on the hypothesis that DETANONOate inhibits a transcription repressor Yin Yang 1 (YY1) that negatively regulates DR5 transcription. Treatment of the prostate carcinoma cell lines with DETANONOate inhibited both NF-kappaB and YY1 DNA-binding activities concomitantly with upregulation of DR5 expression. The direct role of YY1 in the regulation of TRAIL resistance was demonstrated in cells treated with YY1 siRNA resulting in TRAIL-induced apoptosis. The role of YY1 in the transcriptional regulation of DR5 was examined in cells treated with a DR5 luciferase reporter system (pDR5) and two constructs, namely, the pDR5/-605 construct with a deletion of the putative YY1 DNA-binding region (-1224 to -605) and a construct pDR5-YY1 with a mutation of the YY1 DNA-binding site. A significant (3-fold) augmentation of luciferase activity over baseline transfection with pDR5 was observed in cells transfected with the modified constructs. ChIP analysis corroborated the YY1 binding to the DR5 promoter. In vivo, tissues from nude mice bearing the PC-3 xenograft and treated with DETANONOate showed inhibition of YY1 and upregulation of DR5. The present findings demonstrate that YY1 negatively regulates DR5 transcription and expression and these correlated with resistance to TRAIL-induced apoptosis. DETANONOate inhibits both NF-kappaB and YY1 and in combination with TRAIL reverses tumor cell resistance to TRAIL apoptosis.

Transcervical Inoculation with Chlamydia trachomatis Induces Infertility in HLA-DR4 Transgenic and Wild-Type Mice.

2018-01-01

Chlamydia trachomatis is the leading cause of infection-induced infertility in women. Attempts to control this epidemic with screening programs and antibiotic therapy have failed. Currently, a vaccine to prevent C. trachomatis infections is not available. In order to develop an animal model for evaluating vaccine antigens that can be applied to humans, we used C. trachomatis serovar D (strain UW-3/Cx) to induce infertility in mice whose major histocompatibility complex class II antigen was replaced with the human leukocyte antigen DR4 (HLA-DR4). Transcervical inoculation of medroxyprogesterone-treated HLA-DR4 transgenic mice with 5 × 10 5 C. trachomatis D inclusion forming units (IFU) induced a significant reduction in fertility, with a mean number of embryos/mouse of 4.4 ± 1.3 compared to 7.8 ± 0.5 for the uninfected control mice ( P < 0.05). A similar fertility reduction was elicited in the wild-type (WT) C57BL/6 mice (4.3 ± 1.4 embryos/mouse) compared to the levels of the WT controls (9.1 ± 0.4 embryos/mouse) ( P < 0.05). Following infection, WT mice mounted more robust humoral and cellular immune responses than HLA-DR4 mice. As determined by vaginal shedding, HLA-DR4 mice were more susceptible to a transcervical C. trachomatis D infection than WT mice. To assess if HLA-DR4 transgenic and WT mice could be protected by vaccination, 10 4 IFU of C. trachomatis D was delivered intranasally, and mice were challenged transcervically 6 weeks later with 5 × 10 5 IFU of C. trachomatis D. As determined by severity and length of vaginal shedding, WT C57BL/6 and HLA-DR4 mice were significantly protected by vaccination. The advantages and limitations of the HLA-DR4 transgenic mouse model for evaluating human C. trachomatis vaccine antigens are discussed. Copyright © 2017 American Society for Microbiology.

Vesico-vaginal fistula (VVF) was a common ailment among American women in the 19th century. Prior to that time, no successful surgery had been developed for the cure of this condition until Dr J Marion Sims perfected a successful surgical technique in 1849. Dr Sims used female slaves as research subjects over a four-year period of experimentation (1845-1849). This paper discusses the controversy surrounding his use of powerless women and whether his actions were acceptable during that historical period. PMID:8459435

DR-TAMAS: Diffeomorphic Registration for Tensor Accurate Alignment of Anatomical Structures.

In this work, we propose DR-TAMAS (Diffeomorphic Registration for Tensor Accurate alignMent of Anatomical Structures), a novel framework for intersubject registration of Diffusion Tensor Imaging (DTI) data sets. This framework is optimized for brain data and its main goal is to achieve an accurate alignment of all brain structures, including white matter (WM), gray matter (GM), and spaces containing cerebrospinal fluid (CSF). Currently most DTI-based spatial normalization algorithms emphasize alignment of anisotropic structures. While some diffusion-derived metrics, such as diffusion anisotropy and tensor eigenvector orientation, are highly informative for proper alignment of WM, other tensor metrics such as the trace or mean diffusivity (MD) are fundamental for a proper alignment of GM and CSF boundaries. Moreover, it is desirable to include information from structural MRI data, e.g., T1-weighted or T2-weighted images, which are usually available together with the diffusion data. The fundamental property of DR-TAMAS is to achieve global anatomical accuracy by incorporating in its cost function the most informative metrics locally. Another important feature of DR-TAMAS is a symmetric time-varying velocity-based transformation model, which enables it to account for potentially large anatomical variability in healthy subjects and patients. The performance of DR-TAMAS is evaluated with several data sets and compared with other widely-used diffeomorphic image registration techniques employing both full tensor information and/or DTI-derived scalar maps. Our results show that the proposed method has excellent overall performance in the entire brain, while being equivalent to the best existing methods in WM. Copyright © 2016 Elsevier Inc.

Identification of species within the Mycobacterium avium complex (MAC) is difficult, and most current diagnostic laboratory tests cannot distinguish between species included in the complex. Differentiation of species within the MAC is important, as Mycobacterium chimaera has recently emerged as a major cause of invasive cardiovascular infections following open heart surgery. A new commercial diagnostic assay, GenoType NTM-DR ver. 1.0, is intended to differentiate between three species within the MAC, namely, Mycobacterium avium , Mycobacterium intracellulare , and Mycobacterium chimaera In this study, we investigated an archival collection of 173 MAC isolates using 16S rRNA and 16S-23S internal transcribed spacer (ITS) gene sequencing, and GenoType NTM-DR was evaluated for identifying M. chimaera and other species belonging to the MAC. Species identification of 157/173 (91%) isolates with the GenoType NTM-DR assay was in agreement with 16S rRNA and 16S-23S ITS gene sequencing results. Misidentification occurred with 16 isolates which belonged to four species included in the MAC that are rarely encountered in clinical specimens. Despite some limitations of this assay, GenoType NTM-DR had 100% specificity for identifying M. chimaera This novel assay will enable diagnostic laboratories to differentiate species belonging to the Mycobacterium avium complex and to accurately identify M. chimaera It can produce rapid results and is also more cost efficient than gene sequencing methods.

Modeling the relationship between body weight and energy intake: A molecular diffusion-based approach

PubMed Central

2012-01-01

Background Body weight is at least partly controlled by the choices made by a human in response to external stimuli. Changes in body weight are mainly caused by energy intake. By analyzing the mechanisms involved in food intake, we considered that molecular diffusion plays an important role in body weight changes. We propose a model based on Fick's second law of diffusion to simulate the relationship between energy intake and body weight. Results This model was applied to food intake and body weight data recorded in humans; the model showed a good fit to the experimental data. This model was also effective in predicting future body weight. Conclusions In conclusion, this model based on molecular diffusion provides a new insight into the body weight mechanisms.

The dense granular (GRA) proteins of Toxoplasma gondii(T. gondii) have been demonstrated as potential sources of T. gondii vaccine antigens. However, data of the GRA5 protein are limited. This study analyzed twenty-one complete GRA5 sequences of T. gondii GT1, RH, ME49, VEG, MAS, RUB, FOU, p89, VAND, and GAB2-2007-GAL-DOM2 strains to identify potential epitopes restricted by Major Histocompatibility Complex class II (MHC- II) molecules (human leukocyte antigen (HLA)-DP, HLA-DQ, and HLA-DR) in the protein. In all T. gondii strains, peptides positioned at amino acid (aa) 15-29, 16-30, 17-31, 18-32, 19-33, 83-97, 84-98, 86-100, 87-101, 89-103, and 90-104 were predicted to pose high affinity and binding with HLA-DRB1*0101, HLA-DRB1*0301 (DR17), HLA-DRB1*0401 (DR4Dw4), HLA-DRB1*0701, HLA-DRB1*1101, HLA-DRB1*1501 (DR2b), and/or HLA-DRB5*0101. Considering the epitope's affinity, ligation strength, and hydrophilicity, LRLLRRRRRRAIQEE sequence (aa 90-104) restricted by HLA-DRB1*0101, HlA- DRB1*0301 (DR17), and HLA-DRB1*0401 (DR4Dw4) was considered as the most potential MHC-II epitope in GRA5 of T. gondii. These results would be useful for studies concerning in developing T. gondii vaccine and diagnostic method.

Allele-specific HLA-DR typing by mass spectrometry: an alternative to hybridization-based typing methods.

PubMed

Worrall, T A; Schmeckpeper, B J; Corvera, J S; Cotter, R J

2000-11-01

The primer oligomer base extension (PROBE) reaction, combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, is used to characterize HLA-DR2 polymorphism. Alleles are distinguished rapidly and accurately by measuring the mass of primer extension products at every known variable region of HLA-DR2 alleles. Since differentiation of alleles by PROBE relies on measuring differences in extension product mass rather than differences in hybridization properties, mistyped alleles resulting from nonspecific hybridization are absent. The method shows considerable potential for high-throughput screening of HLA-DR polymorphism in a chip-based format, including rapid tissue typing of unrelated volunteer donors.

This story of three SS dentists shows very clearly that the medical code of ethics, under a totalitarian regime, ends where ideology begins. Professor Hugo Blaschke provided dental care to the most eminent Nazi leaders, but he also was the senior SS dentist. He was in charge of dental care in the Waffen-SS, and therefore, he had responsibility for the stocks of dental gold collected from the mouths of those who died in the concentration camps, in order to make dentures for his soldiers. Dr Hermann Pook was the dentist in charge of all the other dentists practising in the concentration camps. He was responsible for gathering statistics on the dental care provided for prisoners in the camps. His instructions were very clear: "No conservation or restorative treatment. Only extractions, and with no anaesthesia!" He was also in charge of gathering the gold that was collected in the camps, for the financial department of the SS. Dr Willy Frank, an Auschwitz dentist, took part in the selection of some of the convoys for the gas chambers. His participation in the collection of gold from the mouths of the dead was also established. These three men were sentenced to prison for War Crimes and Crimes against Humanity.

2015-08-01

TNF-like cytokine 1A (TL1A) and its receptors, death receptor 3 (DR3) and decoy receptor 3 (DcR3) are members of the TNF and TNF receptor superfamilies of proteins, respectively. They constitute a cytokine system that actively interferes with the regulation of immune responses and may participate in the pathogenesis of autoimmune diseases. This review aims to present the current knowledge on the role of the TL1A/DR3/DcR3 system in the pathophysiology of autoimmune rheumatic diseases, with a focus on rheumatoid arthritis (RA). An extensive literature search was performed in the PubMed database using the following keywords: TL1A, death receptor 3, DR3, decoy receptor 3, DcR3, TNFSF15, TNFRSF25, and TNFSF6B. Studies were assessed and selected in view of their relevance to autoimmune rheumatic diseases. The TL1A/DR3/DcR3 axis is a novel immune pathway that participates in the pathogenesis of a variety of autoimmune rheumatic diseases. These molecules may be promising therapeutic targets for inflammatory arthritis. Copyright © 2015 Elsevier Inc. All rights reserved.

Are HLA-DR or TAP genes genetic markers of severity in ulcerative colitis?

The pathogeny of ulcerative colitis (UC) is not yet elucidated, but some arguments suggest the implication of genetic factors. Among the candidate genes, those encoding for HLA class II genotypes have been extensively studied in UC; however, discordant data may be imputable to heterogeneity, characterized by immunological markers such as atypical ANCA (p-ANCA), or to inclusion of more or less intractable UC. The aim of our study is to evaluate the interest of HLA class II and TAP genetic markers to identify different clinical forms of UC, according to p-ANCA status. Unrelated patients with a history of UC (n = 91) and healthy control subjects with no personal or family history of inflammatory bowel diseases (IBD) (n = 200) were included. HLA-DRB1*03 was less frequent in UC patients than in healthy controls (8% vs 28%, PC < 0.03). No association was found with any TAP genotypes. Moreover, there was no association with the HLA-DR2 specificity, either in the entire group of UC patients (38% vs 28%) or in the p-ANCA-positive subgroup of patients (30%). The most consistent finding in the present study is that some genetic markers may characterize intractability in UC patients. HLA-DR2 was associated with poor prognosis, regardless of p-ANCA status. In HLA-DR2 and non-HLA-DR2 groups, colectomy was done in 55% and 27% of patients, respectively, (PC < 0.05). Furthermore, in non-HLA-DR2 patients, p-ANCA could be of interest to characterize those with more severe prognosis. Our results confirm the interest of genetic studies to define UC genetic susceptibility, taking into account intractability of the disease. They do not support the hypothesis that p-ANCA is a subclinical marker of genetic susceptibility to UC.

Does transitioning from computed radiography (CR) to direct radiography (DR) with portable imaging systems affect workflow efficiency?

NASA Astrophysics Data System (ADS)

Gali, Raja L.; Roth, Christopher G.; Smith, Elizabeth; Dave, Jaydev K.

2018-03-01

In digital radiography, computed radiography (CR) technology is based on latent image capture by storage phosphors whereas direct radiography (DR) technology is based either on indirect conversion using a scintillator or direct conversion using a photoconductor. DR-based portable imaging systems may enhance workflow efficiency. The purpose of this work was to investigate changes in workflow efficiency at a tertiary healthcare center after transitioning from CR to DR technology for imaging with portable x-ray units. An IRB exemption was obtained. Data for all inpatient-radiographs acquired with portable x-ray units from July-2014 till June-2015 (period 1) with CR technology (AMX4 or AMX4+ portable unit from GE Healthcare, NX workstation from Agfa Healthcare for digitization), from July-2015 till June-2016 (period 2) with DR technology (Carestream DRX-Revolution x-ray units and DRX-1C image receptors) and from July-2016 till January-2017 (period 3; same DR technology) were extracted using Centricity RIS-IC (GE Healthcare). Duration between the imaging-examination scheduled time and completed time (timesch-com) was calculated and compared using non-parametric tests (between the three time periods with corrections for multiple comparisons; three time periods were used to identify if there were any other potential temporal trends not related to transitioning from CR to DR). IBM's SPSS package was used for statistical analysis. Overall data was obtained from 33131, 32194, and 18015 cases in periods 1, 2 and 3, respectively. Independent-Samples Kruskal-Wallis test revealed a statistically significant difference in timesch-com across the three time periods (χ2(2, n= 83,340) = 2053, p < 0.001). The timesch-com was highest for period 1 i.e., radiographs acquired with CR technology (median: 64 minutes) and it decreased significantly for radiographs acquired with DR technology in periods 2 (median: 49 minutes; p < 0.001) and 3 (median∶ 44 minutes; p < 0.001).

Dr. Robert C. Allen was a gifted educator, as well as experienced ophthalmologist, who was a close personal friend of Dr. Edlich at the University of Virginia Health System. While serving on the faculty at the University of Virginia Health System, Dr. Allen proved to be a compassionate physician, who developed close personal relationships with the residents, faculty, and his patients. Dr. Allen was invited by Dr Edlich to be a member of the Editorial Board of the Journal of Long-Term Effects of Medical Implants. When Dr. Allen told Dr. Edlich that he had ocular melanoma in 2000, this news was a wake-up call to Dr. Edlich on the need to prevent skin cancer, as well as ocular melanoma. Empowered by this news, Dr. Edlich was honored to co-author four articles on skin cancer prevention, as well as the latest article focusing on prevention of ocular melanoma. The Ocular Melanoma Foundation (Richmond, VA (USA)) was founded in 2003 by Dr. Robert C. Allen to increase awareness, enhance education, and provide advocacy among both patients and health care professionals regarding this rare, but potentially lethal cancer. It has a website that provides patient information, up-to-date information and enables communication/ discourse between and among patients and practitioners (admin@ocularmelanoma.org). Dr. Allen died on March 24, 2005, at his home surrounded by family and loved ones. When surgeons are faced with challenging healthcare diseases, Dr. Edlich's mentor, Dr. Owen Wangensteen, advised Dr. Edlich that he should seek the advice and guidance of skilled basic scientists, who are familiar with the problem. Dr. Wangensteen is recognized as the greatest surgical teacher during the 20th century. Consequently, Dr. Edlich enlisted the advice and guidance from the two co-authors of the next article regarding the scientific basis for the selection of sunglasses to prevent the development of cataracts, pterygia, skin cancer, as well as ocular melanoma.

The objective of this article is to provide a portrait of prefrontal lobotomy performed at the Royal Prince Alfred Hospital, Sydney by the Head of Neurosurgery Dr Rex Money and to describe Dr Money's role in the promotion of psychosurgery in Sydney. We draw attention to an oral presentation by Dr Rex Money in 1951, a journal article written by Money, archival information held at the Royal Prince Alfred Hospital, including Dr Money's accounts of his travels and his reports regarding neurosurgery - both internationally and in Australia. Dr Rex Money performed a series of 13 prefrontal lobotomies between 1945 and 1951, and presented the theoretical basis for his series, his operative procedures and the outcomes at the annual meeting of its medical officers' association. Notwithstanding various deficiencies in his clinical research, Money's descriptions give a relatively comprehensive account of one of the first series of prefrontal lobotomies performed in Australia. The current article also describes Dr Money's contributions to the promotion of psychosurgery in Sydney, and illustrates the participation of a senior neurosurgeon and of a major Sydney teaching hospital during the psychosurgery saga. © The Royal Australian and New Zealand College of Psychiatrists 2016.

Role of VMH ketone bodies in adjusting caloric intake to increased dietary fat content in DIO and DR rats.

Le Foll, Christelle; Dunn-Meynell, Ambrose A; Miziorko, Henry M; Levin, Barry E

2015-05-15

The objective of this study was to determine the potential role of astrocyte-derived ketone bodies in regulating the early changes in caloric intake of diet induced-obese (DIO) versus diet-resistant (DR) rats fed a 31.5% fat high-energy (HE) diet. After 3 days on chow or HE diet, DR and DIO rats were assessed for their ventromedial hypothalamic (VMH) ketone bodies levels and neuronal ventromedial hypothalamic nucleus (VMN) sensing using microdialysis coupled to continuous food intake monitoring and calcium imaging in dissociated neurons, respectively. DIO rats ate more than DR rats over 3 days of HE diet intake. On day 3 of HE diet intake, DR rats reduced their caloric intake while DIO rats remained hyperphagic. Local VMH astrocyte ketone bodies production was similar between DR and DIO rats during the first 6 h after dark onset feeding but inhibiting VMH ketone body production in DR rats on day 3 transiently returned their intake of HE diet to the level of DIO rats consuming HE diet. In addition, dissociated VMN neurons from DIO and DR rats were equally sensitive to the largely excitatory effects of β-hydroxybutyrate. Thus while DR rats respond to increased VMH ketone levels by decreasing their intake after 3 days of HE diet, this is not the case of DIO rats. These data suggest that DIO inherent leptin resistance prevents ketone bodies inhibitory action on food intake.

The red light from the Light Emitting Diode (LED) probe shines through the fingers of Dr. Harry Whelan, a pediatric neurologist at the Children's Hospital of Wisconsin in Milwaukee. Dr. Whelan uses the long waves of light from the LED surgical probe to activate special drugs that kill brain tumors. Laser light previously has been used for this type of surgery, but the LED light illuminates through all nearby tissues, reaching parts of tumors that shorter wavelengths of laser light carnot. The new probe is safer because the longer wavelengths of light are cooler than the shorter wavelengths of laser light, making the LED less likely to injure normal brain tissue near the tumor. Also, it can be used for hours at a time while still remaining cool to the touch. The probe was developed for photodynamic cancer therapy under a NASA Small Business Innovative Research Program grant. The program is part of NASA's Technology Transfer Department at the Marshall Space Flight Center.

The electronic data was coming from the Passive Seismic Experiments Package (PSEP) which the Apollo 11 astronauts had just deployed on the surface of the moon. Dr. Lamont is the principal investigator for the PSEP, a component of the Early Apollo Scientific Experiments Package (EASEP). PSEP uses three long-period seismometers and one short-period vertical seismometer for measuring meteoroid impacts and moonquakes. Such data will be useful in determining the interior structure of the moon; for example, does the moon have a core and mantle like Earth? Here, the flapping of the PSEP's solar panels is picked up and registered as a tracing. The PSEP was sensitive enough to pick up the footsteps of astronauts Neil A. Armstrong and Edwin E. Aldrin Jr., as they walked on the moon.

1995-06-01

The professional achievements of Halfdan Mahler, for which he was awarded the 1995 UN World Population Prize, are summarized, and Dr. Mahler's acceptance speech is presented. Dr. Mahler worked for reproductive health and sustainable development during his six years as secretary general of the IPPF. Under his leadership, the IPPF established world standards for family planning and reproductive health. Dr. Mahler also guided creation and implementation of the long-term IPPF strategic plan, Vision 2000. During his tenure as director general of the World Health Organization from 1973 to 1988, he established the special program of education, development, and training for research in human reproduction. Dr. Mahler's acceptance speech sketched a world of the future in which women control their reproductive lives and enjoy equality with men in work and at home, where adolescents understand and control their sexuality, where all children are desired and cared for, and where hard work brings success even in the poorest population sectors. The challenges of achieving this vision are enormous. The world's population will have doubled to 10 billion, and tensions and inequities will persist. But if the vision is not fulfilled, the present population will triple to 15 billion and competition for every kind of resource will be intolerable. In order to succeed, the rights to free and informed reproductive decision making must be guaranteed for every couple. Harmful practices that violate the right to autonomous reproductive decision making, such as early marriage or female genital mutilation, must be eliminated. Governments must commit themselves to educating and providing resources to women so that they can exercise their rights. Family planning services must be extended to the poor and marginal population sectors that still are denied access, and to adolescents who are at risk of unwanted pregnancy and disease.

In this work, we propose DR-TAMAS (Diffeomorphic Registration for Tensor Accurate alignMent of Anatomical Structures), a novel framework for intersubject registration of Diffusion Tensor Imaging (DTI) data sets. This framework is optimized for brain data and its main goal is to achieve an accurate alignment of all brain structures, including white matter (WM), gray matter (GM), and spaces containing cerebrospinal fluid (CSF). Currently most DTI-based spatial normalization algorithms emphasize alignment of anisotropic structures. While some diffusion-derived metrics, such as diffusion anisotropy and tensor eigenvector orientation, are highly informative for proper alignment of WM, other tensor metrics such as the trace or mean diffusivity (MD) are fundamental for a proper alignment of GM and CSF boundaries. Moreover, it is desirable to include information from structural MRI data, e.g., T1-weighted or T2-weighted images, which are usually available together with the diffusion data. The fundamental property of DR-TAMAS is to achieve global anatomical accuracy by incorporating in its cost function the most informative metrics locally. Another important feature of DR-TAMAS is a symmetric time-varying velocity-based transformation model, which enables it to account for potentially large anatomical variability in healthy subjects and patients. The performance of DR-TAMAS is evaluated with several data sets and compared with other widely-used diffeomorphic image registration techniques employing both full tensor information and/or DTI-derived scalar maps. Our results show that the proposed method has excellent overall performance in the entire brain, while being equivalent to the best existing methods in WM. PMID:26931817

To determine the underlying mechanism for the differential expression, the extent of promoter methylation in tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-related genes acting downstream of TRAIL was examined in early and advanced gastric carcinomas. The extent of promoter methylation in the DR4, DR5, DcR1, DcR2, and CASP8 genes was quantified using bisulfite modification and methylation-specific polymerase chain reaction. The promoters for DcR1, DcR2, and CASP8 were largely unmethylated in early gastric carcinoma, advanced gastric carcinoma, and controls, with no significant difference among them. Protein levels of DR4, DcR1, and DcR2 as revealed by immunohistochemistry correlated with the extent of the respective promoter methylation (P < 0.05 in all cases). Hypomethylation, rather than hypermethylation, of the DR4 promoter was noted in invasive gastric malignancies, with statistical significance (P = 0.003). The promoter methylation status of TRAIL receptors in gastric carcinoma may have clinical implications for improving therapeutic strategies in patients with gastric carcinoma.

Predominant antitumor effects by fully human anti-TRAIL-receptor2 (DR5) monoclonal antibodies in human glioma cells in vitro and in vivo

Tumor necrosis factor–related apoptosis-inducing ligand (TRAIL/Apo2 L) preferentially induces apoptosis in human tumor cells through its cognate death receptors DR4 or DR5, thereby being investigated as a potential agent for cancer therapy. Here, we applied fully human anti-human TRAIL receptor monoclonal antibodies (mAbs) to specifically target one of death receptors for TRAIL in human glioma cells, which could also reduce potential TRAIL-induced toxicity in humans. Twelve human glioma cell lines treated with several fully human anti-human TRAIL receptor mAbs were sensitive to only anti-DR5 mAbs, whereas they were totally insensitive to anti-DR4 mAb. Treatment with anti-DR5 mAbs exerted rapid cytotoxicity and lead to apoptosis induction. The cellular sensitivity was closely associated with cell-surface expression of DR5. Expression of c-FLIPL, Akt, and Cyclin D1 significantly correlated with sensitivity to anti-DR5 mAbs. Primary cultures of glioma cells were also relatively resistant to anti-DR5 mAbs, exhibiting both lower DR5 and higher c-FLIPL expression. Downregulation of c-FLIPL expression resulted in the sensitization of human glioma cells to anti-DR5 mAbs, whereas overexpression of c-FLIPL conferred resistance to anti-DR5 mAb. Treatment of tumor-burden nude mice with the direct agonist anti-DR5 mAb KMTR2 significantly suppressed growth of subcutaneous glioma xenografts leading to complete regression. Similarly, treatment of nude mice bearing intracerebral glioma xenografts with KMTR2 significantly elongated lifespan without tumor recurrence. These results suggest that DR5 is the predominant TRAIL receptor mediating apoptotic signals in human glioma cells, and sensitivity to anti-DR5 mAbs was determined at least in part by the expression level of c-FLIPL and Akt. Specific targeting of death receptor pathway through DR5 using fully human mAbs might provide a novel therapeutic strategy for intractable malignant gliomas. PMID:20511188

A Host Susceptibility Gene, DR1, Facilitates Influenza A Virus Replication by Suppressing Host Innate Immunity and Enhancing Viral RNA Replication

PubMed Central

Hsu, Shih-Feng; Su, Wen-Chi; Jeng, King-Song

2015-01-01

ABSTRACT Influenza A virus (IAV) depends on cellular factors to complete its replication cycle; thus, investigation of the factors utilized by IAV may facilitate antiviral drug development. To this end, a cellular transcriptional repressor, DR1, was identified from a genome-wide RNA interference (RNAi) screen. Knockdown (KD) of DR1 resulted in reductions of viral RNA and protein production, demonstrating that DR1 acts as a positive host factor in IAV replication. Genome-wide transcriptomic analysis showed that there was a strong induction of interferon-stimulated gene (ISG) expression after prolonged DR1 KD. We found that beta interferon (IFN-β) was induced by DR1 KD, thereby activating the JAK-STAT pathway to turn on ISG expression, which led to a strong inhibition of IAV replication. This result suggests that DR1 in normal cells suppresses IFN induction, probably to prevent undesired cytokine production, but that this suppression may create a milieu that favors IAV replication once cells are infected. Furthermore, biochemical assays of viral RNA replication showed that DR1 KD suppressed viral RNA replication. We also showed that DR1 associated with all three subunits of the viral RNA-dependent RNA polymerase (RdRp) complex, indicating that DR1 may interact with individual components of the viral RdRp complex to enhance viral RNA replication. Thus, DR1 may be considered a novel host susceptibility gene for IAV replication via a dual mechanism, not only suppressing the host defense to indirectly favor IAV replication but also directly facilitating viral RNA replication. IMPORTANCE Investigations of virus-host interactions involved in influenza A virus (IAV) replication are important for understanding viral pathogenesis and host defenses, which may manipulate influenza virus infection or prevent the emergence of drug resistance caused by a high error rate during viral RNA replication. For this purpose, a cellular transcriptional repressor, DR1, was identified from

GENESI-DR Portal: a scientific gateway to distributed repositories

GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) is a European Commission (EC)-funded project, kicked-off early 2008 lead by ESA; partners include Space Agencies (DLR, ASI, CNES), both space and no-space data providers such as ENEA (I), Infoterra (UK), K-SAT (N), NILU (N), JRC (EU) and industry as Elsag Datamat (I), CS (F) and TERRADUE (I). GENESI-DR intends to meet the challenge of facilitating "time to science" from different Earth Science disciplines in discovery, access and use (combining, integrating, processing, …) of historical and recent Earth-related data from space, airborne and in-situ sensors, which are archived in large distributed repositories. "Discovering" which data are available on a "geospatial web" is one of the main challenges ES scientists have to face today. Some well- known data sets are referred to in many places, available from many sources. For core information with a common purpose many copies are distributed, e.g., VMap0, Landsat, and SRTM. Other data sets in low or local demand may only be found in a few places and niche communities. Relevant services, results of analysis, applications and tools are accessible in a very scattered and uncoordinated way, often through individual initiatives from Earth Observation mission operators, scientific institutes dealing with ground measurements, service companies or data catalogues. In the discourse of Spatial Data Infrastructures, there are "catalogue services" - directories containing information on where spatial data and services can be found. For metadata "records" describing spatial data and services, there are "registries". The Geospatial industry coins specifications for search interfaces, where it might do better to reach out to other information retrieval and Internet communities. These considerations are the basis for the GENESI-DR scientific portal, which adopts a simple model allowing the geo-spatial classification and discovery of

DR-nm23 gene expression in neuroblastoma cells: relationship to integrin expression, adhesion characteristics, and differentiation.

Neuroblastoma, a childhood tumor originating from cells of the embryonic neural crest, retains the ability to differentiate, yielding cells with epithelial-Schwann-like, neuronal, or melanocytic characteristics. Since nm23 gene family members have been proposed to play a role in cellular differentiation, as well as in metastasis suppression, we investigated whether and how DR-nm23, a recently identified third member of the human nm23 gene family, might be involved in neuroblastoma differentiation. Three neuroblastoma cell lines (human LAN-5, human SK-N-SH, and murine N1E-115) were used in these experiments; cells from two of the lines (SK-N-SH and N1E-115) were also studied after being stably transfected with a plasmid containing a full-length DR-nm23 complementary DNA. Cellular expression of specific messenger RNAs and proteins was assessed by use of standard techniques. Cellular adhesion to a variety of protein substrates was also evaluated. DR-nm23 messenger RNA levels in nontransfected LAN-5 and SK-N-SH cells generally increased with time after exposure to differentiation-inducing conditions; levels of the other two human nm23 messenger RNAs (nm23-H1 and nm23-H2) remained essentially constant. Transfected SK-N-SH cells overexpressing DR-nm23 exhibited some characteristics of differentiated cells (increased vimentin and collagen type IV expression) even in the absence of differentiation-inducing conditions. Compared with control cells, DR-nm23-transfected cells exposed to differentiation-inducing conditions showed a greater degree of growth arrest (SK-N-SH cells) and greater increases in integrin protein expression, especially of integrin beta1 (N1E-115 cells). DR-nm23-transfected N1E-115 cells also showed a marked increase in adhesion to collagen type I-coated tissue culture plates that was inhibited by preincubation with an anti-integrin beta1 antibody. DR-nm23 gene expression appears to be associated with differentiation in neuroblastoma cells and may affect

Magnetic porous microspheres are widely used in modern wastewater treatment technology due to their simple and quick dye adsorption and separation functions. In this article, we prepared porous polymethylmethacrylate (PMMA) microspheres by the seed-swelling method, followed by in situ formation of iron oxide (Fe3O4) nanoparticles within the pore. Then, we used diazo-resin (DR) to encapsulate the porous magnetic microspheres and achieve PMMA@Fe3O4@DR magnetic material. We studied the different properties of magnetic microspheres by different dye adsorption experiments before and after the encapsulation and demonstrated that the PMMA@Fe3O4@DR microspheres can be successfully used as a reusable absorbent for fast and easy removal of anionic and aromatic dyes from wastewater and can maintain excellent magnetic and adsorption properties in harsh environments.

Recombinant TRAIL and agonistic antibodies to death receptors (DRs) have been in clinical trial but displayed limited anti-cancer efficacy. Lack of functional DR expression in tumors is a major limiting factor. We report here that chromatin regulator KDM4A/JMJD2A, not KDM4B, has a pivotal role in silencing tumor cell expression of both TRAIL and its receptor DR5. In TRAIL-sensitive and -resistant cancer cells of lung, breast and prostate, KDM4A small-molecule inhibitor compound-4 (C-4) or gene silencing strongly induces TRAIL and DR5 expression, and causes TRAIL-dependent apoptotic cell death. KDM4A inhibition also strongly sensitizes cells to TRAIL. C-4 alone potently inhibits tumor growth with marked induction of TRAIL and DR5 expression in the treated tumors and effectively sensitizes them to the newly developed TRAIL-inducer ONC201. Mechanistically, C-4 does not appear to act through the Akt-ERK-FOXO3a pathway. Instead, it switches histone modifying enzyme complexes at promoters of TRAIL and DR5 transcriptional activator CHOP gene by dissociating KDM4A and nuclear receptor corepressor (NCoR)-HDAC complex and inducing the recruitment of histone acetylase CBP. Thus, our results reveal KDM4A as a key epigenetic silencer of TRAIL and DR5 in tumors and establish inhibitors of KDM4A as a novel strategy for effectively sensitizing tumors to TRAIL pathway-based therapeutics.

Recombinant TRAIL and agonistic antibodies to death receptors (DRs) have been in clinical trial but displayed limited anti-cancer efficacy.

In order to detect epitope-specific CD4+ T cells in mycobacterial or viral infections in the context of human class II major histocompatibility complex protein human leukocyte antigen (HLA)-DR3, two HLA-DR3 tetrameric molecules were successfully produced. One contained an immunodominant HLA-DR3-restricted T-cell epitope derived from the 65-kDa heat-shock protein of Mycobacterium tuberculosis, peptide 1-13. For the other tetramer, we used an HLA-DR3-restricted T-cell epitope derived from cytomegalovirus (CMV) pp65 lower matrix protein, peptide 510-522, which induced high levels of interferon (IFN)-gamma-producing CD4+ T cells in three of four HLA-DR3-positive CMV-seropositive individuals up to 0.84% of CD4+ T cells by intracellular cytokine staining. In peripheral blood mononuclear cells from M. tuberculosis-exposed, Mycobacterium bovis bacille Calmette-Guérin (BCG)-vaccinated, or CMV-seropositive individuals, we were able to directly detect with both tetramers epitope-specific T cells up to 0.62% and 0.45% of the CD4+ T-cell population reactive to M. tuberculosis and CMV, respectively. After a 6-day culture with peptide p510-522, the frequency of CMV-specific tetramer-binding T cells was expanded up to 9.90% tetramer+ CFSElow (5,6-carboxyfluorescein diacetate succinimidyl ester) cells within the CD4+ T-cell population, further confirming the specificity of the tetrameric molecules. Thus, HLA-DR3/peptide tetrameric molecules can be used to investigate HLA-DR3-restricted antigen-specific CD4+ T cells in clinical disease or after vaccination.

Oroxylin A reverses CAM-DR of HepG2 cells by suppressing Integrinβ1 and its related pathway

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhu, Binbin; Zhao, Li; Zhu, Litao

Oroxylin A, a naturally occurring monoflavonoid extracted from Scutellariae radix, shows effective anticancer activities and low toxicities both in vivo and in vitro in previous studies. In this study, we investigated whether the CAM-DR model of HepG2 cells showed resistance to cytotoxic agents compared with normally cultured HepG2 cells. Furthermore, after the treatment of Paclitaxel, less inhibitory effects and decreased apoptosis rate were detected in the model. Data also revealed increased expression of Integrinβ1 might be responsible for the resistance ability. Moreover, Integrinβ1-siRNA-transfected CAM-DR HepG2 cells exhibited more inhibitory effects and higher levels of apoptosis than the non-transfected CAM-DR cells.more » The data corroborated that Integrinβ1 played a significant role in CAM-DR. After the treatment of weakly-toxic concentrations of Oroxylin A, the apoptosis induced by Paclitaxel in the CAM-DR model increased dramatically. Western blot assay revealed Oroxylin A markedly down-regulated the expression of Integrinβ1 and the activity of related pathway. As a conclusion, Oroxylin A can reverse the resistance of CAM-DR via inhibition of Integrinβ1 and its related pathway. Oroxylin A may be a potential candidate of a CAM-DR reversal agent. Highlights: ► Adhesion of HepG2 cells to fibronectin exhibited resistance to Paclitaxel. ► The resistance was associated with the increased expression of Integrinβ1. ► Knocking down Integrinβ1 can increase the toxicity of Paclitaxel on CAM-DR model. ► Oroxylin A reversed the resistance by suppressing Integrinβ1 and related pathway.« less

René Leriche and “Philosophy of Surgery” in the light of contemporary medical ethics

PubMed Central

Akça, Tamer; Aydın, Süha

Prof. Dr. René Leriche was a famous French surgeon who lived between 1879 and 1955. After working as a vascular surgeon in Lyon, he was appointed professor at the University of Strasbourg in 1924 and later the Paris Collége de France in 1937. Leriche had proposed vascular patches as the ideal treatment for obliterated vascular segments and advocated the necessity of sympathectomy in arterial diseases in the 1920s. He defined “Leriche Syndrome” in 1923 which is known by his name and which develops as a result of incomplete obstruction of the aortic bifurcation. René Leriche wrote a monograph entitled “La Chirurgie de la Douleur-Pain Surgery” in 1940 and he also became a pioneer in the sympathectomy procedure for pain treatment. René Leriche focused on topics that must be remembered again today, including surgery advanced into science, the physiological basis of surgery, research methods, as well as issues such as business technology, humanity in surgery, surgical essence and surgeon’s qualifications in the book entitled “La Philosophie de la Chirurgie-Philosophy of Surgery” that he wrote in 1951. In this review, the issues that Prof. Dr. René Leriche addressed in middle of the 20th century were revised in the light of contemporary medical ethics. PMID:25931863

Invariant chain (Ii) or CD74 is a non-polymorphic glycoprotein, which apart from its role as a chaperone dedicated to MHCII molecules, is known to be a high-affinity receptor for macrophage migration inhibitory factor (MIF). The present study aimed to define the roles of CD74 and MIF in the immune surveillance escape process. Towards this direction, the cell lines HL-60, Raji, K562 and primary pre-B leukemic cells were examined for expression and secretion of MIF. Flow cytometry analysis detected high levels of MIF and intracellular/membrane CD74 expression in all leukemic cells tested, while MIF secretion was shown to be inversely proportional to intracellular HLA-DR (DR) expression. In the MHCII-negative cells, IFN-γ increased MIF expression and induced its secretion in HL-60 and K562 cells, respectively. In K562 cells, CD74 (Iip33Iip35) was shown to co-precipitate with HLA-DOβ (DOβ), inhibiting thus MIF or DR binding. Induced expression of DOα in K562 (DOα-DOβ+) cells in different transfection combinations decreased MIF expression and secretion, while increasing surface DR expression. Thus, MIF could indeed be part of the antigen presentation process.

DR-Integrator: a new analytic tool for integrating DNA copy number and gene expression data.

DNA copy number alterations (CNA) frequently underlie gene expression changes by increasing or decreasing gene dosage. However, only a subset of genes with altered dosage exhibit concordant changes in gene expression. This subset is likely to be enriched for oncogenes and tumor suppressor genes, and can be identified by integrating these two layers of genome-scale data. We introduce DNA/RNA-Integrator (DR-Integrator), a statistical software tool to perform integrative analyses on paired DNA copy number and gene expression data. DR-Integrator identifies genes with significant correlations between DNA copy number and gene expression, and implements a supervised analysis that captures genes with significant alterations in both DNA copy number and gene expression between two sample classes. DR-Integrator is freely available for non-commercial use from the Pollack Lab at http://pollacklab.stanford.edu/ and can be downloaded as a plug-in application to Microsoft Excel and as a package for the R statistical computing environment. The R package is available under the name 'DRI' at http://cran.r-project.org/. An example analysis using DR-Integrator is included as supplemental material. Supplementary data are available at Bioinformatics online.

Revisiting hypervelocity stars after Gaia DR2

NASA Astrophysics Data System (ADS)

Boubert, D.; Guillochon, J.; Hawkins, K.; Ginsburg, I.; Evans, N. W.; Strader, J.

2018-06-01

Hypervelocity stars are intriguing rare objects traveling at speeds large enough to be unbound from the Milky Way. Several mechanisms have been proposed for producing them, including the interaction of the Galaxy's super-massive black hole (SMBH) with a binary; rapid mass-loss from a companion to a star in a short-period binary; the tidal disruption of an infalling galaxy and finally ejection from the Large Magellanic Cloud. While previously discovered high-velocity early-type stars are thought to be the result of an interaction with the SMBH, the origin of high-velocity late type stars is ambiguous. The second data release of Gaia (DR2) enables a unique opportunity to resolve this ambiguity and determine whether any late-type candidates are truly unbound from the Milky Way. In this paper, we utilize the new proper motion and velocity information available from DR2 to re-evaluate a collection of historical data compiled on the newly-created Open Fast Stars Catalog. We find that almost all previously-known high-velocity late-type stars are most likely bound to the Milky Way. Only one late-type object (LAMOST J115209.12+120258.0) is unbound from the Galaxy. Performing integrations of orbital histories, we find that this object cannot have been ejected from the Galactic centre and thus may be either debris from the disruption of a satellite galaxy or a disc runaway.

The 1998 Nobel Prize in Physiology and Medicine has been awarded jointly to North-American scientists, Dr Robert F. Furchgott, Louis J. Ignarro and Ferid Murad, for their discoveries in relation to "nitric oxide as a signalling molecule in the cardiovascular system". This has raised an important polemic because of the exclusion the South-American scientist, now nationalized British, Dr. Salvador Moncada. This short historical review examines some of the fundamental contributions to the knowledge in this field. It shows the sequence of the discoveries and the communication of them to the scientific community by the rewarded scientists and by Dr. Moncada. It is based on some fundamental publications in order to better understand this story, which does not coincide with the writing in 1996 by the Lasker Prize Committee, and which in 1998 was re-written again by the Nobel Committee of the Swedish Academy. More than 90 universities, academies and societies have acknowledged Dr. Moncada up to now with priority in the discovery of the fact that nitric oxide is released by endothelial cells, and the revealing of its metabolic way. More than 20,000 citations of their fundamental papers endorse in the scientific community his primacy in this field. Even Robert Furchgott, author of the brilliant discovery of the endothelium derived relaxing factor, that opened this field to the science, declared about the award of the 1998 Nobel Prize: "I feel that the Nobel Prize Committee could have made an exception this year and chosen a fourth person, Salvador Moncada (to share the prize)".

Parallax uncertainties are in the range of up to 0.04 milliarcsecond for sources at G<15, around 0.1mas for sources with G=17 and at the faint end, the uncertainty is of the order of 0.7mas at G=20. The corresponding uncertainties in the respective proper motion components are up to 0.06mas/yr (for G<15mag), 0.2mas/yr (for G=17mag) and 1.2mas/yr (for G=20mag). The Gaia DR2 parallaxes and proper motions are based only on Gaia data; they do no longer depend on the Tycho-2 Catalogue. Median radial velocities (i.e. the median value over the epochs) for more than 6 million stars with a mean G magnitude between about 4 and 13 and an effective temperature (Teff) in the range of about 3550 to 6900K. This leads to a full six-parameter solution: positions and motions on the sky with parallaxes and radial velocities, all combined with mean G magnitudes. The overall precision of the radial velocities at the bright end is in the order of 200-300m/s while at the faint end the overall precision is approximately 1.2km/s for a Teff of 4750K and about 2.5km/s for a Teff of 6500K. An additional set of more than 200 million sources for which a two-parameter solution is available: the positions on the sky (alpha,delta) combined with the mean G magnitude.

Tryptophol is a natural component isolated from vinegar produced from the boiled extract of black soybean. We have reported that tryptophol induces apoptosis in U937 cells via activation of caspase-8 followed by caspase-3. Tryptophol, however, did not affect human peripheral blood lymphocytes (PBL). In this study, we found that tryptophol enhances formation of a death-inducing signaling complex including death receptor (DR) 5. Cell viability and induction of apoptosis by tryptophol was reduced by transfection with decoy receptor (DcR) 1. These results indicate that tryptophol induces apoptosis through DR5 and that the resistance of PBL to tryptophol-induced apoptosis might be due to competition from DcR1.

The Very Large Array in Socorro, New Mexico has been used to study the Zeeman Effect in the 21cm HI line seen in absorption against radio sources in the Cygnus X region. Cygnus X is geometrically favorable for Zeeman effect observations as the region lies along the mean field direction of the diffuse interstellar medium (ISM) of the galaxy. We present observations of two compact HII regions within Cygnus X, DR 22 and ON 2. The data show magnetic field strengths of the order -80 μG toward DR 22 alone with no significant detections toward ON 2. This information is used to estimate the magnetic energy of the DR 22 star-forming cloud, and allows for a complete analysis of the energetics of the region revealing the role of the magnetic field.

In August 1883, a Chair of physics was created in Nantes with Dr. Leduc (1853-1939) as the first teacher. Physician and biophysicist, he was a pioneer and visionary in many areas, including the "synthetic biology". Dr. Leduc immediately understood the importance of the discovery of the X-ray by Röntgen in 1896 for medicine. As early as in 1905, he successfully treated cancers with irradiation. In 1935, he was awarded a gold key by the American Congress of Physical Therapy for his accomplishments. The teachings of Dr Leduc largely influenced his student and successor, Dr René Gauducheau's (1881-1968) orientation towards physical and radiological sciences. This latter introduced radium therapy, and began his endeavor for the creation of a cancer center which opened its doors in 1924, recently becoming the Institut de Cancérologie de l'Ouest in 2011.

HLA antigens vary in different ethnical groups and in Chile there are no reports on the frequency of these antigens in a normal representative population. The few existing studies are of indigenous populations and control groups, without including HLA-DR antigens. Therefore, the aim of this study was to study the frequency of HLA A, B and C antigens in 349 individuals and HLA-DR in 257, using the microlymphocytotoxicity method, and compared the results with those on normal caucasian populations (Europe and USA). Significant differences were found for 7 antigens of group A, 10 of group B, 4 of group C and 6 of group DR. The observed difference allow us to conclude that the population from Santiago has a distinct HLA antigen distribution. This fact must be bore in mind future studies in genetics, paternity or autoimmune diseases.

Death Receptor 5 (DR5) agonists demonstrate anti-tumor activity in preclinical models but have yet to demonstrate robust clinical responses. A key limitation may be the lack of patient selection strategies to identify those most likely to respond to treatment. To overcome this limitation, we screened a DR5 agonist Nanobody across >600 cell lines representing 21 tumor lineages and assessed molecular features associated with response. High expression of DR5 and Casp8 were significantly associated with sensitivity, but their expression thresholds were difficult to translate due to low dynamic ranges. To address the translational challenge of establishing thresholds of gene expression, we developed a classifier based on ratios of genes that predicted response across lineages. The ratio classifier outperformed the DR5+Casp8 classifier, as well as standard approaches for feature selection and classification using genes, instead of ratios. This classifier was independently validated using 11 primary patient-derived pancreatic xenograft models showing perfect predictions as well as a striking linearity between prediction probability and anti-tumor response. A network analysis of the genes in the ratio classifier captured important biological relationships mediating drug response, specifically identifying key positive and negative regulators of DR5 mediated apoptosis, including DR5, CASP8, BID, cFLIP, XIAP and PEA15. Importantly, the ratio classifier shows translatability across gene expression platforms (from Affymetrix microarrays to RNA-seq) and across model systems (in vitro to in vivo). Our approach of using gene expression ratios presents a robust and novel method for constructing translatable biomarkers of compound response, which can also probe the underlying biology of treatment response.

To address the translational challenge of establishing thresholds of gene expression, we developed a classifier based on ratios of genes that predicted response across lineages. The ratio classifier outperformed the DR5+Casp8 classifier, as well as standard approaches for feature selection and classification using genes, instead of ratios. This classifier was independently validated using 11 primary patient-derived pancreatic xenograft models showing perfect predictions as well as a striking linearity between prediction probability and anti-tumor response. A network analysis of the genes in the ratio classifier captured important biological relationships mediating drug response, specifically identifying key positive and negative regulators of DR5 mediated apoptosis, including DR5, CASP8, BID, cFLIP, XIAP and PEA15. Importantly, the ratio classifier shows translatability across gene expression platforms (from Affymetrix microarrays to RNA-seq) and across model systems (in vitro to in vivo). Our approach of using gene expression ratios presents a robust and novel method for constructing translatable biomarkers of compound response, which can also probe the underlying biology of treatment response.

The crystal structure of DR6 in complex with the amyloid precursor protein provides insight into death receptor activation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Xu, Kai; Olsen, Olav; Tzvetkova-Robev, Dorothea

The amyloid precursor protein (APP) has garnered considerable attention due to its genetic links to Alzheimer's disease. Death receptor 6 (DR6) was recently shown to bind APP via the protein extracellular regions, stimulate axonal pruning, and inhibit synapse formation. Here, we report the crystal structure of the DR6 ectodomain in complex with the E2 domain of APP and show that it supports a model for APP-induced dimerization and activation of cell surface DR6.

Immune-mediated diseases strongly associating with human leukocyte antigen (HLA) alleles are likely linked to specific antigens. These antigens are presented to T cells in the form of peptides bound to HLA molecules on antigen presenting cells, e.g. dendritic cells, macrophages or B cells. The identification of HLA-DR-bound peptides presents a valuable tool to investigate the human immunopeptidome. The lung is likely a key player in the activation of potentially auto-aggressive T cells prior to entering target tissues and inducing autoimmune disease. This makes the lung of exceptional interest and presents an ideal paradigm to study the human immunopeptidome and to identify antigenic peptides. Our previous investigation of HLA-DR peptide presentation in the lung required high numbers of cells (800 × 106 bronchoalveolar lavage (BAL) cells). Because BAL from healthy nonsmokers typically contains 10–15 × 106 cells, there is a need for a highly sensitive approach to study immunopeptides in the lungs of individual patients and controls. In this work, we analyzed the HLA-DR immunopeptidome in the lung by an optimized methodology to identify HLA-DR-bound peptides from low cell numbers. We used an Epstein-Barr Virus (EBV) immortalized B cell line and bronchoalveolar lavage (BAL) cells obtained from patients with sarcoidosis, an inflammatory T cell driven disease mainly occurring in the lung. Specifically, membrane complexes were isolated prior to immunoprecipitation, eluted peptides were identified by nanoLC-MS/MS and processed using the in-house developed ClusterMHCII software. With the optimized procedure we were able to identify peptides from 10 × 106 cells, which on average correspond to 10.9 peptides/million cells in EBV-B cells and 9.4 peptides/million cells in BAL cells. This work presents an optimized approach designed to identify HLA-DR-bound peptides from low numbers of cells, enabling the investigation of the BAL immunopeptidome from individual patients and

2002-01-01

The research project "SIFTER: Scintillating Fiber Telescopes for Energetic Radiation, Gamma-Ray Applications" approved under the NASA High Energy Astrophysics Research Program. The principal investigator of the proposal was Prof. Geoffrey N. Pendleton, who is currently on extended leave from UAH. Prof. William S. Paciesas administered the grant during Dr. Pendleton's absence. The project was originally funded for one year from 6/8/2000 to 6/7/2001. Due to conflicts with other commitments by the PI, the period of performance was extended at no additional cost until 6/30/2002. The goal of this project was to study scintillating fiber pair-tracking gamma-ray telescope configurations specifically designed to perform imaging and spectroscopy in the 5 - 250 MeV energy range. The main efforts were concentrated in two areas: 1) development of tracking techniques and event reconstruction algorithms, with particular emphasis on angular resolution; and 2) investigation of coded apertures as a means to improve the instrument angular resolution at low energies.

A Study of the Impact of Death Receptor 4 (DR4) Gene Polymorphisms in Alzheimer's Disease.

Excessive apoptosis is believed to play a role in many degenerative and non-degenerative neurological diseases including Alzheimer's disease (AD). Much recent data suggest that apoptotic mechanisms may represent the missing link between Aβ deposition and proteolysis of tau protein. However, there is emerging evidence that apoptotic mechanisms may play a role in Alzheimer's Disease pathogenesis in the absence of overt apoptosis. TNF-related apoptosis inducing ligand receptor 1 (Death Receptor 4, DR4) might impair the apoptotic signal transduction and lead to dysregulation of the homeostasis between cell survival and cell death. The aim of our study was to further investigate the relationship between genetic variants of DR4 and Alzheimer's Disease. Case control study. Sixty-eight patients with AD were included in the study. The control group comprised 72 subjects without signs of neurodegenerative diseases, as evidenced by the examination.DNA was extracted from whole blood using the salting-out procedure. Genotypes were identified by restriction fragment length polymorphism analysis of polymerase chain reaction (PCR-RFLP) products. We observed significant differences in the genotypic distribution of the rs6557634 polymorphism in AD patients compared with controls (p<0.05); our data suggest that the GA genotype in rs6557634 could be protective against AD (p<0.05). However, there were no significant differences between AD patients and control groups in terms of the DR4 rs20575 polymorphism (p>0.05) and the DR4 rs20576 polymorphism (p>0.05). According to haplotype analysis of the DR4 gene for rs6557634, rs20575 and rs20576 polymorphisms, GCA and GCC haplotypes might be a risk factor for AD. Also, we have shown that ACA, GGC and GGA haplotypes might be protective factors against AD. The present results indicate for the first time the possible contribution of the DR4 gene rs6557634, rs20575, rs20576 polymorphisms in Alzheimer's Disease, which may influence susceptibility

Hauser, S P

Kombucha, a fungal infusion, is a 'symbiotic mixture' of bacteria, yeasts, tea and sugar. A number of components are listed, but exact analyses are not published. On the basis of 'thorough detoxification', Kombucha is claimed to be a prophylactic and therapeutic agent in countless diseases, such as rheumatism, intestinal disorders, ageing and cancer. All 'stages of the Sklenar blood picture' have to be treated with Kombucha Drink, Kombucha Drops, coli preparations and Gelum oral-rd for a period of months. A litre-bottle costs 13 DM, the blood analysis 150 Sfr. In the 1960's Dr. R. Sklenar developed a 'biological cancer therapy with Kombucha as the main agent' and his own system of diagnosing cancer. Sklenar's diagnosis of cancer is based on iris diagnosis and demonstration of the causative organism by means of a 'Blood picture according to Dr. Sklenar'. He claims, on one hand, that cancer is only one of the many metabolic diseases and, on the other, that viruses, in his view parasitic microorganisms in general, are responsible for the pathogenesis of cancer. No preclinical and nor investigations are available, as 'success has proved him (Dr. Sklenar) to be right'. The seven 'case histories' described have no solid medical data. There is so far no evidence to support the claim that Kombucha offers 'effective biological treatment of cancer'.

Dr. Robert G. Heath: a controversial figure in the history of deep brain stimulation.

The history of psychosurgery is filled with tales of researchers pushing the boundaries of science and ethics. These stories often create a dark historical framework for some of the most important medical and surgical advancements. Dr. Robert G. Heath, a board-certified neurologist, psychiatrist, and psychoanalyst, holds a debated position within this framework and is most notably remembered for his research on schizophrenia. Dr. Heath was one of the first physicians to implant electrodes in deep cortical structures as a psychosurgical intervention. He used electrical stimulation in an attempt to cure patients with schizophrenia and as a method of conversion therapy in a homosexual man. This research was highly controversial, even prior to the implementation of current ethics standards for clinical research and often goes unmentioned within the historical narrative of deep brain stimulation (DBS). While distinction between the modern practice of DBS and its controversial origins is necessary, it is important to examine Dr. Heath's work as it allows for reflection on current neurosurgical practices and questioning the ethical implication of these advancements.

Dr Samuel Johnson's movement disorder.

PubMed Central

Murray, T J

1979-01-01

Dr Samuel Johnson was noted by his friends to have almost constant tics and gesticulations, which startled those who met him for the first time. He also made noises and whistling sounds; he made repeated sounds and words and irregular or blowing respiratory noises. Further, he often carried out pronounced compulsive acts, such as touching posts, measuring his footsteps on leaving a room, and performing peculiar complex gestures and steps before crossing a threshold. His symptoms of (a) involuntary muscle jerking movements and complex motor acts, (b) involuntary vocalisation, and (c) compulsive actions constitute the symptom complex of Gilles de la Tourette syndrome (Tourette's syndrome), from which Johnson suffered most of his life. This syndrome is of increasing interest recently because it responds to haloperidol, and because there are new insights into a possible biochemical basis for the tics, vocalisations, and compulsions.

Role of FAT/CD36 in fatty acid sensing, energy, and glucose homeostasis regulation in DIO and DR rats.

PubMed

Le Foll, Christelle; Dunn-Meynell, Ambrose A; Levin, Barry E

2015-02-01

Hypothalamic fatty acid (FA) sensing neurons alter their activity utilizing the FA translocator/receptor, FAT/CD36. Depletion of ventromedial hypothalamus (VMH) CD36 with adeno-associated viral vector expressing CD36 shRNA (AAV CD36 shRNA) leads to redistribution of adipose stores and insulin resistance in outbred rats. This study assessed the requirement of VMH CD36-mediated FA sensing for the regulation of energy and glucose homeostasis in postnatal day 5 (P5) and P21 selectively bred diet-induced obese (DIO) and diet-resistant (DR) rats using VMH AAV CD36 shRNA injections. P5 CD36 depletion altered VMH neuronal FA sensing predominantly in DIO rats. After 10 wk on a 45% fat diet, DIO rats injected with VMH AAV CD36 shRNA at P21 ate more and gained more weight than DIO AAV controls, while DR AAV CD36 shRNA-injected rats gained less weight than DR AAV controls. VMH CD36 depletion increased inguinal fat pad weights and leptin levels in DIO and DR rats. Although DR AAV CD36 shRNA-injected rats became as obese as DIO AAV controls, only DIO control and CD36 depleted rats became insulin-resistant on a 45% fat diet. VMH CD36 depletion stunted linear growth in DIO and DR rats. DIO rats injected with AAV CD36 shRNA at P5 had increased fat mass, mostly due to a 45% increase in subcutaneous fat. They were also insulin-resistant with an associated 71% increase of liver triglycerides. These results demonstrate that VMH CD36-mediated FA sensing is a critical factor in the regulation of energy and glucose homeostasis and fat deposition in DIO and DR rats.

Although tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis in various malignant cells, several cancers including human hepatocellular carcinoma (HCC) exhibit potent resistance to TRAIL-induced cell death. The aim of this study is to evaluate the anti-cancer potential of capsaicin in TRAIL-induced cancer cell death. As indicated by assays that measure phosphatidylserine exposure, mitochondrial activity and activation of caspases, capsaicin potentiated TRAIL-resistant cells to lead to cell death. In addition, we found that capsaicin induces the cell surface expression of TRAIL receptor DR5, but not DR4 through the activation Sp1 on its promoter region. Furthermore, we investigated that capsaicin-induced DR5more » expression and apoptosis are inhibited by calcium chelator or inhibitors for calmodulin-dependent protein kinase. Taken together, our data suggest that capsaicin sensitizes TRAIL-mediated HCC cell apoptosis by DR5 up-regulation via calcium influx-dependent Sp1 activation. Highlights: ► Capsaicin sensitizes TRAIL-induced apoptosis through activation of caspases. ► Capsaicin induces expression of DR5 through Sp1 activation. ► Capsaicin activates calcium signaling pathway.« less
