Simian Sarcoma Virus—Transformed Cells Secrete a Mitogen Identical to Platelet-Derived Growth Factor (1984)

Normal rat kidney (NRK) cells transformed by simian sarcoma virus (SSV) release into the culture medium a biologically active mitogen with properties identical to those of human platelet-derived growth factor (PDGF). Like PDGF, the growth factor derived from SSV-NRK cells was shown to be stable to heat and sensitive to reducing agents. It was capable of inhibiting binding of labeled PDGF to the receptor on human fibroblasts. It also stimulated the phosphorylation of the same membrane protein (185 kilodaltons) in isolated plasma membranes from human fibroblasts. Immunoprecipitation of metabolically labeled proteins released by SSV-NRK cells showed that a 34-kilodalton protein was specifically precipitated by antiserum to PDGF. Upon reduction, this protein had a molecular size of 17 kilodaltons. PDGF has been shown to consist of two 14- to 18-kilodalton proteins linked by disulfide bonds.
A genetic map of chromosome 20q12-q13.1: multiple highly polymorphic microsatellite and RFLP markers linked to the maturity-onset diabetes of the young (MODY) locus. (1993)

Multiple highly polymorphic markers have been used to construct a genetic map of the q12-q13.1 region of chromosome 20 and to map the location of the maturity-onset diabetes of the young (MODY) locus. The genetic map encompasses 23 cM and includes 11 loci with PIC values > .50, seven of which have PICs > .70. New dinucleotide repeat polymorphisms associated with the D20S17, PPGB, and ADA loci have been identified and mapped. The dinucleotide repeat polymorphisms have increased the PIC of the ADA locus to .89 and, with an additional RFLP at the D20S17 locus, the PIC of the D20S17 locus to .88. The order of the D20S17 and ADA loci determined genetically (cen-ADA-D20S17-qter) was confirmed by multicolor fluorescence in situ hybridization. The previously unmapped PPGB marker is closely linked to D20S17, with a two-point lod score of 50.53 at theta = .005. These markers and dinucleotide repeat markers associated with the D20S43, D20S46, D20S55, D20S75, and PLC1 loci and RFLPs at the D20S16, D20S17, D20S22, and D20S33 have been used to map the MODY locus on chromosome 20 to a 13-cM (sex averaged) interval encompassing ADA, D20S17, PPGB, D20S16, and D20S75 on the long arm of chromosome 20 and to create a genetic framework for additional genetic and physical mapping studies of the region. With these multiple highly polymorphic loci, any MODY family of appropriate size can be tested for the chromosome 20 linkage.
Phase II Study of Gemcitabine Chemotherapy Alone for Locally Advanced Pancreatic Carcinoma: JCOG0506 (2010)

Gemcitabine monotherapy demonstrated far better survival than historical data for chemoradiotherapy with 5-fluorouracil with mild toxicities. Gemcitabine could be consider as a standard treatment for locally advanced pancreatic cancer.
Estimation of breathing interval from the photoplethysmographic signals in children (2005)

Two important parameters that are generally under continual observation during clinical monitoring are heart rate (HR) variability and breathing interval (BI) of patients. Current HR monitoring during night-long childhood respiratory sleep studies is well tolerated but BI monitoring requires instrumentation, like nasal cannula, that can be less accommodating for children. In this study, BI was extracted from the photoplethysmographic (PPG) signals using a two-stage signal processing technique termed zero-phase digital filtering. Eight children (7 male) aged 8.6 +/- 2.6 years were recruited to perform two breathing activities: during tidal and with customized externally applied inspiratory resistive loading (IRL). The accuracy of BI derived from the PPG signals was compared with that estimated by a calibrated air pressure transducer in children. Statistical analysis revealed that mean BI attained from the PPG signals were significantly related during tidal breathing (r(2) = 0.76; range 0.61-0.83; p < 0.05) and with the IRL (r(2) = 0.79; range 0.68-0.85; p < 0.05) in the absence of motion artefacts. Preliminary findings herein suggest that besides having the capability to monitor HR and arterial blood oxygen saturation measurements, the PPG signals can be used to derive BI for children. This can be an attractive alternative for children who are more disturbed by intrusive techniques in prolonged clinical monitoring.
The tilt cursor (2007)

In order to improve stimulus-response compatibility of touchpad in pen-based user interface, we present the tilt cursor, i.e. a cursor dynamically reshapes itself to providing the 3D orientation cue of pen. We also present two experiments that evaluate the tilt cursor's performance in circular menu selection and specific marking menu selection tasks. Results show that in a specific marking menu selection task, the tilt cursor significantly outperforms the shape-fixed arrow cursor and the live cursor [4]. In addition, results show that by using the tilt cursor, the response latencies for adjusting drawing directions are smaller than that by using the other two kinds of cursors.
Structural studies and polymorphism in amorphous solids and liquids at high pressure (2006)

When amorphous materials are compressed their structures are expected to change in response to densification. In some cases, the changes in amorphous structure can be discontinuous and they can even have the character of first-order phase transitions. This is a phenomenon referred to as polyamorphism. Most evidence for polyamorphic transitions between low and high density liquids or analogous transformations between amorphous forms of the same substance to date has been indirect and based on the changes in thermodynamic and other structure-related properties with pressure. Recent studies using advanced X-ray and neutron scattering methods combined with molecular dynamics simulations are now revealing the details of structural changes in polyamorphic systems as a function of pressure. Various "two state" or "two species" models are used to understand the anomalous densification behaviour of liquids with melting curve maxima or regions of negative melting slope. Thermodynamic analysis of the two state model leads to the possibility of low- to high-density liquid transitions caused by differences in bulk thermodynamic properties between different amorphous forms and on the degree of cooperativity between low- and high-density structural configurations. The potential occurrence of first-order transitions between supercooled liquids is identified as a critical-like phenomenon. In this tutorial review we discuss the background to polyamorphism, incorporating the experimental observations, simulation studies and the two-state models. We also describe work carried on several systems that are considered to be polyamorphic.
Unusual ancestry of dehydratases associated with quinate catabolism in Acinetobacter calcoaceticus (1995)

Catabolism of quinate to protocatechuate requires the consecutive action of quinate dehydrogenase (QuiA), dehydroquinate dehydratase (QuiB), and dehydroshikimate dehyratase (QuiC), Genes for catabolism of protocatechuate are encoded by the pca operon in the Acinetobacter calcoaceticus chromosome. Observations reported here demonstrate that A. calcoaceticus qui genes are clustered in the order quiBCXA directly downstream from the pca operon. Sequence comparisons indicate that quiX encodes a porin, but the specific function of this protein has not been clearly established. Properties of mutants created by insertion of omega elements show that quiBC is expressed as part of a single transcript, but there is also an independent transcriptional initiation site directly upstream of quiA. The deduced amino acid sequence of QuiC does not resemble any other known sequence. A. calcoaceticus QuiB is most directly related to a family of enzymes with identical catalytic activity and biosynthetic AroD function in coliform bacteria. Evolution of A. calcoaceticus quiB appears to have been accompanied by fusion of a leader sequence for transport of the encoded protein into the inner membrane, and the location of reactions catalyzed by the mature enzyme may account for the failure of A. calcoaceticus aroD to achieve effective complementation of null mutations in quiB. Analysis of a genetic site where a DNA segment encoding a leader sequence was transposed adds to evidence suggesting horizontal transfer of nucleotide sequences within genes during evolution.
A placebo-controlled trial of aprepitant for cough in lung cancer. (2015)

2 Background: There are no evidence-based therapies for cough in lung cancer (LC).The neurokinin-1 (NK-1) pathway is implicated in cough. Aprepitant is an NK-1 antagonist used as an antiemetic. We assess aprepitant as an antitussive, using objective daytime ambulatory cough monitoring (ACM) as the primary endpoint. Methods: LC patients with a “bothersome” cough were enrolled on an exploratory single-arm randomised double-blind crossover trial and received 125mg aprepitant on day 1 and 80mg on days 2 and 3 or matched placebo capsules. After a 3 day wash out,patients crossed over to placebo or aprepitant for 3 days (days 7-9). They completed ACM and validated subjective cough tools. Results: 20 LC patients were enrolled between 7th Oct 2013-3rd Nov 2014; mean age 66 yrs (SD 7.69); 60% (n=12) female; 70% (n=14) ex, 25% (n=5) current and 5% (n=1) never smokers respectively. 20% (n=4), 55% (n=11) and 25% (n=5) had a performance status of 0, 1 and 2 respectively. The majority (80% n=16) had non-small cell LC; half (n=10) had advanced stage; 20% (n=4) were on anticancer therapy. Daytime cough frequency was 15.9 (95%CI 10.1-28.3 n=19), 12.8 (95% CI 8.7-18.8 n=18) and 16.2 (11.3-23.0 n=19) coughs/hr at baseline, on aprepitant and on placebo respectively: p=0.03. Visual analogue scale scores (range 0-100, high score=worse severity) were 57.0mm (95% CI 47.4-67.2 n=19), 40.8mm, (95%CI 34.3-47.3 n=18), and 49.8mm (95%CI 44.2-55.4 n=19) at baseline, on aprepitant and on placebo respectively: p=0.008. The Manchester Cough in Lung Cancer Scale score (range 1-50, high score = worse cough impact) was 25.2 (95%CI 23.0-28.0 n=19), 19.5 (95%CI 17.8-21.2 n=18) and 21.7 (20.3-23.1 n=18) at baseline, on aprepitant and on placebo respectively: p&lt;0.001.There were no serious adverse events. Conclusions: This is the first trial to assess the efficacy of a novel antitussive using validated subjective and objective cough tools in LC and the first to investigate a centrally acting NK-1 antagonist in humans. Aprepitant treatment was associated with statistically significant improvements in objective and subjective scores. The NK-1 receptors may be key mediators in cough in LC. It is possible to run a robust trial using validated measures with clinically meaningful endpoints in a LC population. Clinical trial information: ISRCTN16200035.
High-mobility low-bandgap conjugated copolymers based on indacenodithiophene and thiadiazolo[3,4-c]pyridine units for thin film transistor and photovoltaic applications (2011)

Two new semiconducting polymers based on indacenodithiophene and thiadiazolo[3,4-c]pyridine units were synthesized viaStille coupling polymerization. The polymers, PIDTPyT and PIDTDTPyT, exhibited main absorption bands in the range of 550–800 nm while their absorption maxima were located at around 700 nm in films. With two additional thiophene spacers, PIDTDTPyT showed a broader absorption band but a 20 nm blue-shifted maximum peak compared to that of PIDTPyT. Both of the polymers possess low bandgaps (∼1.6 eV) and deep energy levels for both the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). Organic field-effect transistors (OFETs) device measurements indicate that PIDTPyT and PIDTDTPyT have high hole carrier mobilities of 0.066 and 0.045 cm2 V−1s−1, respectively, with the on/off ratio on the order of 106. Bulk heterojunction photovoltaic devices consisting of the copolymers and PC71BM gave power conversion efficiencies (PCE) as high as 3.91% with broadband photo-response in the range of 300–800 nm. The relationships between the photovoltaic performance and film morphology, energy levels, hole mobilities are discussed.
Table of Cases (2014)

The 1948 UN Convention on the Prevention and Punishment of the Crime of Genocide (“Genocide Convention”) has a special standing in international law, as well as in international politics. For 60 years the crime of genocide has been recognised as the most horrendous crime in international law, famously designated the ‘crime of crimes’. On the occasion of the 60th anniversary of its adoption the UN High Commissioner for Human Rights stated that ‘genocide is the ultimate form of discrimination’. In the same context the chief prosecutor at the International Criminal Court described the Genocide Convention as a ‘visionary and founding text for the Court’. The Convention has influenced the subsequent development of many different areas of international law. For example, the 1951 Advisory Opinion on the Genocide Convention enabled the International Court of Justice to shape the modern regime of reservations to treaties. More recently the prohibition against genocide has become a crucial pillar of international criminal law, with genocide being one of the core crimes falling under the jurisdiction of the UN ad hoc tribunals, the Extraordinary Chambers in the Courts of Cambodia, and the permanent International Criminal Court since the 1990s.

Recombinant Human Tumor Necrosis Factor-α: Effects on Proliferation of Normal and Transformed Cells in Vitro (1985)

Modulation of the growth of human and murine cell lines in vitro by recombinant human tumor necrosis factor-alpha (rTNF-alpha) and recombinant human interferon-gamma (rIFN-gamma) was investigated. rTNF-alpha had cytostatic or cytolytic effects on only some tumor cell lines. When administered together with rIFN-gamma, rTNF-alpha showed enhanced antiproliferative effects on a subset of the cell lines tested. In contrast to its effects on sensitive tumor cells, rTNF-alpha augmented the growth of normal diploid fibroblasts. Variations in the proliferative response induced by rTNF-alpha were apparently not due to differences in either the number of binding sites per cell or their affinity for rTNF-alpha. These observations indicate that the effects of rTNF-alpha on cell growth are not limited to tumor cells, but rather that this protein may have a broad spectrum of activities in vivo.
Extracellular Signal-Regulated Kinases Regulate Dendritic Growth in Rat Sympathetic Neurons (2004)

NGF activates several signaling cascades in sympathetic neurons. We examined how activation of one of these cascades, the ERK/MAP (extracellular signal-regulated kinase/mitogen-activated protein) kinase pathway, affects dendritic growth in these cells. Dendritic growth was induced by exposure to NGF and BMP-7 (bone morphogenetic protein-7). Exposure to NGF increased phosphorylation of ERK1/2. Unexpectedly, two MEK (MAP kinase kinase) inhibitors (PD 98059 and U 0126) enhanced dendritic growth, and a ligand, basic FGF, that activates the ERK pathway inhibited the growth of these processes. The enhancement of dendritic growth by PD 98059 was associated with an increase in the number of axo-dendritic synapses, and it appeared to represent a specific morphogenic effect because neither axonal growth nor cell survival was affected. In addition, increased dendritic growth was not observed after exposure to inhibitors of other signaling pathways, including the phosphatidylinositol-3-kinase inhibitor LY 294002. Dendritic growth was also increased in cells transfected with dominant-negative mutants of MEK1 and ERK2 but not with dominant-negative mutants of MEK5 and ERK5, suggesting that ERK1/2 is the primary mediator of this effect. Exposure to BMP-7 induces nuclear translocation of Smad1 (Sma- and Mad-related protein 1), and PD 98059 treatment potentiated nuclear accumulation of Smad-1 induced by BMP-7 in sympathetic neurons, suggesting a direct enhancement of BMP signaling in cells treated with an MEK inhibitor. These observations indicate that one of the signaling cascades activated by NGF can act in an antagonistic manner in sympathetic neurons and reduce the dendritic growth induced by other NGF-sensitive pathways.
Acute Hyperglycemia Induced by Ketamine/Xylazine Anesthesia in Rats: Mechanisms and Implications for Preclinical Models (2005)

The effects of anesthetic agents, commonly used in animal models, on blood glucose levels in fed and fasted rats were investigated. In fed Sprague-Dawley rats, ketamine (100 mg/kg)/xylazine (10 mg/kg) (KX) produced acute hyperglycemia (blood glucose 178.4 +/- 8.0 mg/dl) within 20 min. The baseline blood glucose levels (104.8 +/- 5.7 mg/dl) reached maximum levels (291.7 +/- 23.8 mg/dl) at 120 min. Ketamine alone did not elevate glucose levels in fed rats. Isoflurane also produced acute hyperglycemia similar to KX. Administration of pentobarbital sodium did not produce hyperglycemia in fed rats. In contrast, none of these anesthetic agents produced hyperglycemia in fasted rats. The acute hyperglycemic effect of KX in fed rats was associated with decreased plasma levels of insulin, adrenocorticotropic hormone (ACTH), and corticosterone and increased levels of glucagon and growth hormone (GH). The acute hyperglycemic response to KX was dose-dependently inhibited by the specific alpha2-adrenergic receptor antagonist yohimbine (1-4 mg/kg). KX-induced changes of glucoregulatory hormone levels such as insulin, GH, ACTH, and corticosterone were significantly altered by yohimbine, whereas the glucagon levels remained unaffected. In conclusion, the present study indicates that both KX and isoflurane produce acute hyperglycemia in fed rats. The effect of KX is mediated by modulation of the glucoregulatory hormones through stimulation of alpha2-adrenergic receptors. Pentobarbital sodium did not produce hyperglycemia in either fed or fasted rats. Based on these findings, it is suggested that caution needs to be taken when selecting anesthetic agents, and fed or fasted state of animals in studies of diabetic disease or other models where glucose and/or glucoregulatory hormone levels may influence outcome and thus interpretation. However, fed animals are of value when exploring the hyperglycemic response to anesthetic agents.
Development and application of a microbeam plasma generator (1992)

A microbeam plasma was successfully generated by using an originally designed capacitively coupled rf plasma reactor which was composed of a needle cathode (1 mm φ), a cylindrical anode (3 mm φ), and a quartz tubing inserted between the cathode and anode. When the reactor was operated in open air and helium was steadily fed as a discharge gas, a plasma beam (φ&amp;lt;2 mm) blew out into air. Conditions for generating a stable plasma were investigated. Preliminary results are presented on the etching of Si by this beam plasma, as well as an emission analysis of the etching plasma.
Mechanism of Photosolvolytic Rearrangement of p-Hydroxyphenacyl Esters:  Evidence for Excited-State Intramolecular Proton Transfer as the Primary Photochemical Step (1999)

The photosolvolytic rearrangement of a variety of p-hydroxyphenacyl esters and related compounds 7−16 has been studied in solutions with up to 50% aqueous content, using product studies, triplet quenchers, and nanosecond laser flash photolysis. The p-hydroxyphenacyl moiety has recently been proposed as a new and efficient photoactivated protecting group in aqueous solution. Practical applications have been demonstrated, but much less is known about the mechanism of photoreaction. Our data support a novel mechanism in which the primary photochemical step from the singlet excited state is formal intramolecular proton transfer from the phenolic proton to the carbonyl oxygen of the distal ketone, mediated by solvent water, to generate the corresponding p-quinone methide phototautomer. This reactive intermediate (most likely in its excited state) subsequently expels the carboxylic acid with concerted rearrangement to a spiroketone intermediate, which subsequently leads to the final observed product, p-hydroxyphenylacetic acid. An alternative mechanism is deprotonation of the phenolic proton, loss of the carboxylate, and rearrangement to the spiroketone, all in one concerted primary photochemical step from S1.
Collagen-induced arthritis in C57BL/6 (H-2b) mice: new insights into an important disease model of rheumatoid arthritis (2000)

Collagen-induced arthritis (CIA) is a widely used model of rheumatoid arthritis (RA) and has been important for understanding autoimmunity. CIA is purportedly restricted to mice bearing the MHC class II H-2q or H-2r haplotypes. In this study, we re-examined established concepts regarding susceptibility to CIA. We found mice derived from the C57BU6 (B6) (H-2b) background can develop CIA with high incidence (60-70%), and sustained severity by using an immunization procedure modified for optimum response in DBA/1 (D1) (H-2q) mice. Clinically and histologically the B6 disease resembles that of D1 mice and is dependent on immunization with type II collagen, as well as on B and CD4+ T cells. In contrast, 129/Sv mice, which share H-2b, are resistant to CIA. We conclude that susceptibility to CIA may reflect immunization conditions and/or important contributions from non-MHC genes, revealed by different immunization protocols. A practical outcome is that CIA can be directly applied to gene knockout mice generated from B6 embryonic stem cells without need for backcross onto the D1 background. This model may lead to improved understanding of autoimmunity in CIA and RA and may provide a platform for analysis of the contribution of non-MHC genes to CIA.
Phase I/II trial of131I-MN-14 F(ab)2 anti-carcinoembryonic antigen monoclonal antibody in the treatment of patients with metastatic medullary thyroid carcinoma (1999)

Therapy with (131)I-MN-14 F(ab)2 is well tolerated and shows evidence of biochemical and radiologic antitumor activity. HAMA development suggests that humanized MAbs will be required in trials with repeated dose schedules. Further dose escalation, alone or in combination with other therapy modalities, is indicated for future trials, preferably with humanized anti-CEA MAbs.
Synthesis of Functionalized Pyridines by Substitution of Hetarenium-Activated Pentachloropyridine with Bisnucleophiles (2006)

Pyridines, acting as heteroaromatic N-nucleophiles, 4-aminopyridine as an N,N-bisnucleophile, and 3,4-diaminopyridine as an N,N,N-trisnucleophile, all reacted with 4-(dimethylamino)-1-(2,3,5,6-tetrachloropyridin-4-yl)pyridinium chloride to give tris­pyridinio-substituted 3,5-dichloropyridines. Reaction of the same pyridinium chloride with O,O-bisnucleophiles such as 1,3-propanediol, hydroquinone, and resorcine, or the O,O,O-nucleophile phloroglucine, formed new Cl2,Cl3,O4,Cl5,Cl6 and O2,Cl3,O4,Cl5,Cl6-substituted pyridines. S,O-Bisnucleophiles, such as 2-sulfanylethanol or 3-sulfanylpropionic acid gave the corresponding S-substituted pyridines (x-ray analysis). The (pyridin-4-yl)propionic acid was converted into bis(pyridinio)pyridine-4-thiol, an example of the rare class of N2,Cl3,S4,Cl5,N6-substituted pyridines.
