Death Related to Pleural and Pericardial Effusions Following Chemoradiotherapy in a Patient with Advanced Cancers of the Esophagus and Stomach (2007)

Chemoradiotherapy improves therapeutic outcome in many different types of cancer. However, there is concern about the occurrence of delayed complications, as patients are surviving longer. Because patients with esophageal cancer receive a wide range of irradiation field to the mediastinum and the heart, they may have delayed complications of heart and lung functions as previously reported in Hodgkin's disease. We presented a case of death related to uncontrollable pleural and pericardial effusions in a patient with advanced cancers of the esophagus and stomach who achieved a complete remission following chemoradiotherapy and salvage gastric resection, focusing on detailed pathophysiological conditions related to concurrent chemoradiotherapy.

Structural Analysis of Secreted Root Slime from Maize (<i>Zea mays</i> L.) (1986)

Secreted slime isolated from the incubation medium of Zea mays roots maintained axenically contains fucose, arabinose, xylose, galactose, and glucose as the major monosaccharides. The slime preparation contains low levels (3% weight/weight [w/w]) of uronic acids. Methylation analysis reveals an extraordinarily diverse range of glycosyl residues. The fucosyl residues are primarily terminal (60%) and 3-linked (33%) with a relatively small proportion being 2-linked (6%). The methylation data are consistent with, but not proof of, the presence of a range of polymers including arabinogalactan-proteins (AGPs), xyloglucans, arabinoxylans, and glucans in the slime. The specific binding of the beta-glucosyl Yariv reagent, a dye which binds and precipitates AGPs, to the slime preparation and to the outer periclinal epidermal cell wall surface in root sections, is further evidence for the presence of AGPs. Low levels of phenolic acids (approximately 0.17% w/w), in particular trans-ferulic acid, and protein (approximately 6% w/w) were also detected.
A class of analytical methods that compensate for attenuation and spatially-variant resolution in 2D SPECT (1996)

An infinite class of closed-form methods was developed by the authors last year for image reconstruction in 2D SPECT with uniform attenuation. In the work reported here, the authors extended their approach to develop a class of closed-form methods that compensate for the effects of both uniform attenuation and distance-dependent spatial resolution in 2D SPECT. These methods, which are characterized by an index n that can be assigned any real number, are exact in the absence of noise but propagate noise differently. The authors implemented this class of methods for SPECT image reconstruction in both computer-simulation and real-data studies. The results demonstrate that this class of methods corrects effectively for the aforementioned effects. Extensive computer simulation studies indicate that the method obtained with n=2, which the authors had proved to be the optimal choice of n in 2D SPECT when only attenuation is present, also provides the smallest global image variance among the methods in the class when compensation for both uniform attenuation and distance-dependent spatial resolution is performed.
Use of hydrogenation in structural and electronic studies of gap states in amorphous germanium (1976)

A method of hydrogenating sputtered amorphous Ge has been developed for systematically studying the variation of the electronic properties with the number of dangling bonds. The role of incorporated hydrogen was established by the correlation of x-ray diffraction, electron paramagnetic resonance, and optical spectroscopy. A model for the logistics of incorporation of hydrogen was also developed and compared with experiment. The origin of the states in the gap of partially coordinated amorphous Ge was traced to the dangling bonds on void surfaces. These states span a large fraction of the energy gap of partially coordinated material, to the extent that transitions between them completely determine the optical absorption below photon energies of about 0.6 eV. (Optical absorption, across the band gap itself, in fully coordinated material, does not occur until about 1 eV.) However, the electron spin density is much smaller than the dangling-bond density, indicating that electrons most often pair to form weak molecular bonds or bipolarons on the void surfaces. Finally, the temperature dependence of the EPR linewidth appears to be correlated with the temperature dependence of the nonactivated conductivity.
Flexible cross-domain event delivery for quality-managed multimedia applications (2005)

To meet end users' quality-of-service (QoS) requirements, online quality management for multimedia applications must include appropriate allocation of the underlying computing platform's resources. Previous work has developed novel operating system (OS) functionality for dynamic QoS management, including multimedia or real-time CPU schedulers and OS extensions for online performance monitoring and for adaptations, as well as QoS-aware applications that adapt their behavior to gain additional benefits from such functionality. This article describes a general OS mechanism that may be used to implement a wide variety of online quality management functions. ECalls is a communication mechanism that implements multiple cross-domain calling conventions that can be customized to the quality management needs of applications. The ECalls mechanism is based on the notions of events, event channels, and event handlers. Using events, applications can share relevant QoS attributes with OS services, and OS-level resource management services can efficiently provide monitoring data to target applications or application managers. Dynamically generated event handlers can be used to customize event delivery to meet diverse application needs, for example, to achieve high scalability for Web servers or small jitter for real-time data delivery.
Exchange reactions between (a) ethylaluminium chlorides or aluminium halides and (b) various silanes or trimethyltin chloride (1968)

Metathetical exchange reactions between (a) ethylaluminium chlorides or aluminium chloride and (b) various silanes or trimethyltin chloride proceed under quite mild conditions. The Al–Et bond is cleaved more readily than the Al–Cl bond [e.g., 2Me3SiBr +(EtAlCl2)2→ 2Me3SiEt + Al2Br2Cl4].
Termite diversity in Brazil (Insecta: Isoptera). (2006)

The current knowledge of the termite faunas in various parts of Brazil is reviewed. The biology, reproduction, nesting and feeding habits as well as spatial distribution of these soil insects are described. Different methods for sampling of termites and the current state of the taxonomy of Brazilian termites are also covered. More or less distinct termite faunas can be recognized in the major biomes (i.e., tropical forests, cerrado, Atlantic forest, caatinga and Pantanal), with significant differences in diversity, abundance and importance. In addition, the relationship between termites and soils is briefly discussed. There are two conflicting aspects of the impact of termites in agroecosystems: their positive services on the soil and the fact that some species can damage living plants.
NDE Techniques for Reliable Inspection of Carbon Steel Tubes (2006)

Ferromagnetic tubes in Heat Exchangers, Boilers, Air Fin Coolers are most common in the Petrochemical Industry. Carbon Steel, an inexpensive material has good mechanical properties and heat transfer capabilities. However, it is often employed in conditions where corrosion if it sets in, acts very fast. Over the years with shrinking maintenance budgets and longer intervals between plant shutdowns the need for reliable inspection of these units has increased. The advent of digital technology, several enhancements to the inspection equipment based on RFEC, Magnetic Flux Leakage, Ultrasonic IRIS have taken place. Each of these techniques has its own merits and demerits. This paper presents an overview of the techniques available for carbon steel inspection discussing their merits and demerits.. It also presents a methodology of selecting the right combination of techniques to achieve reliable inspection results using practical case studies of field work carried out.
Chiral bicyclic [2.2.2] octadiene ligands for Rh-catalysed catalytic asymmetric conjugate additions to acyclic enones: a quantitative structure–property relationship (2012)

A series of chiral bicyclic [2.2.2]diene ligands gave variable ee values for Rh-catalysed asymmetric conjugate addition to an acyclic enone. The interplay between electronic and steric effects was captured in a robust predictive quantitative structure-property relationship (QSPR) model for enantioselectivity.
Changes in Immunospecificity and Biologic Activity of Bovine Insulin Due to Subsequent Removal of the Amino Acids B1, B2 and B3 (1974)

The influence of splitting off the N-terminal amino acids B1, B2 and B3 of bovine insulin on the binding of these derivatives to antibodies raised with bovine insulin in guinea pigs and on biologic insulin activities is investigated. In comparison with bovine insulin the standard free energies −ΔF°1 for complex formation between high affinity antibodies Ak1 and des-PheB1-insulin or des-(Phe-Val)B1-2-insulin are reduced to 77 per cent and 76.3 per cent respectively, with a further decrease to 68 per cent for des-(Phe-Val-Asn)B1-3-[PyrB4] insulin. The standard free energy -ΔF°2 for complex formation between low affinity antibodies Ak2 and des-PheB1-insulin drops to 48.4 per cent. Further splitting off of the N-terminal amino acids B2 and B3 completely abolishes the antigen binding to Ak2. The ability of both des-PheB1-insulin and des-(Phe-Val)B1-2-insulin to lower the in vivo blood sugar level does not differ significantly from bovine insulin, whereas the in vivo activity of des-(Phe-Val-Asn)B1-3-[PyrB4] insulin decreases to 70±7 per cent. The in vitro biologic activity, tested on isolated fat cells, is slightly reduced to 89±9 per cent for des-PheB1-insulin, to 86±3 per cent for des-(Phe-Val)B1-2-insulin and to 68±6 per cent for des-(Phe-Val-Asn) B1-3-[PyrB4] insulin.
CRM1 mediates nuclear-cytoplasmic shuttling of mature microRNAs (2009)

Drosha-processed microRNAs (miRNAs) have been shown to be exported from the nucleus to the cytoplasm by Exportin 5, where they are processed a second time to generate mature miRNAs. In this work we show that miRNAs also use CRM1 for nuclear-cytoplasmic shuttling. Inhibition of CRM1 by Leptomycin B results in nuclear accumulation of miRNA guide sequences. Nuclear to cytoplasmic transport can be actively competed by synthetic small interfering RNAs, indicating that this pathway is shared by different classes of processed small RNAs. We also find that CRM1 coimmunoprecipitates with Ago-1, Ago-2, Topo2alpha, EzH2, and Mta, consistent with a role of Argonautes and small RNAs in chromatin remodeling.
A natural gradient experiment on solute transport in a sand aquifer: 1. Approach and overview of plume movement (1986)

A large‐scale field experiment on natural gradient transport of solutes in groundwater has been conducted at a site in Borden, Ontario. Well‐defined initial conditions were achieved by the pulse injection of 12 m 3 of a uniform solution containing known masses of two inorganic tracers (chloride and bromide) and five halogenated organic chemicals (bromoform, carbon tetrachloride, tetrachloroethylene, 1,2‐dichlorobenzene, and hexachloroethane). A dense, three‐dimensional array of over 5000 sampling points was installed throughout the zone traversed by the solutes. Over 19,900 samples have been collected over a 3‐year period. The tracers followed a linear horizontal trajectory at an approximately constant velocity, both of which compare well with expectations based on water table contours and estimates of hydraulic head gradient, porosity, and hydraulic conductivity. The vertical displacement over the duration of the experiment was small. Spreading was much more pronounced in the horizontal longitudinal than in the horizontal transverse direction; vertical spreading was very small. The organic solutes were retarded in mobility, as expected.

Role of sewage phosphorus in coastal water bioenergy production (2000)

A study was carried out on the quantity and speciation of phosphorus in a sewage originating from Tuticorin town and discharging the contents in the Fishing Harbour area. Four prominent peaks were observed in the distribution of total phosphorus and during most of the months the concentration remained above 4 mgP/l. The annual mean contribution of otal soluble phosphorus (86.73%) to total phosphorus was higher than that of particulate phosphorus (13.27%). Since all the chemical species of phosphorus are eventually converted into biologically utilisable form, the anticipated increment in energy production calculated front the stoichiometric composition of plankton [(CH 2 O) 106 (NH 3 ) 16 H 3 PO 4 ] was to the tune of 1300 tonne C/yr. Assuming that all the three sewages of Tuticorin discharge comparable quantity of wastewater, the anticipated hike in primary energy synthesis was around 3900 × 10 7 kcal. Considering three trophic levels from phytoplankton production to fish production the extra fish production due to sewage phosphorus was calculated as 132.60 tonne/year. According to Winberg's transformation, the surplus production of bioenergy due to be boosted fishery potential was around 132.6 × 10 6 kcal/year.
BILATERAL GIANT ANEURYSMS OF THE INTERNAL CAROTID ARTERY (1972)

An unusual case of bilateral giant aneurysms of the internal carotid artery, one arising from the intracavernous portion of the right internal carotid artery and the other from the supraclinoid portion of the left internal carotid artery, is reported. Socalled megadolichobasilar anomaly is associated with such giant aneurysms of the internal carotid artery. Characteristic findings were seen in plain roentgenograms of the skull, especially in the laminagrams, bilateral carotid angiograms, right retrograde brachial angiograms, pneumoencephalograms, cavernous sinus venograms and brain scans. In contrast to the many roentgenologic findings, the clinical manifestations were few. There was a history of epistaxis and blurred vision of the left eye. Neurologic examination revealed bilateral optic atrophies and decreased visual acuity of the left eye with an upper quadrant temporal anopia. The patient had no extraocular muscle palsy, no olfactory trouble, and no evidence of hypopituitarism.
Synthesis and biological properties of some 3-((N-subtstituted-amino)pyridinium-4-thiomethyl)-7-((2-amino-thiazol-4-yl)-2-(Z)-(methoxyimino)acetamido)ceph-3-em-4-carboxylates. (1993)

The synthesis and antibacterial activity of a series of beta-lactamase stable, broad spectrum 7-[2-(2-amino-thiazol-4-yl)-2-(Z)-(methoxyimino)acetamido]-cephalo sporins, characterised by a C-3-[N-(substituted-amino)pyridinium-4-thiomethyl] group, is described. Gram-positive and Gram-negative bacteria including extended spectrum beta-lactamase-producing strains were most susceptible to the N-amino- and N-methylamino derivatives (3a) and (3b); with the exception of Pseudomonas aeruginosa, (3b) was more active in vitro and in vivo than cefpirome or ceftazidime.
Human ventricular refractoriness. Effects of cycle length, pacing site and atropine. (1976)

The effective refractory period of the right ventricle (ERP-V) was measured in 27 patients during atrial or ventricular pacing using the ventricular extra stimulus method. Pacing was conducted with impulses of 1.5-2 times diastolic threshold. The ERP-V was directly related to the basic cycle length (BCL) although the ERP-V was always greater for atrial pacing than for ventricular pacing at a given BCL. The ratio ERP-V/BCL was greater at shorter cycle lengths indicating that a larger fraction of the cycle was refractory at faster heart rates. The ratio ERP-V/QT interval did not change over a range of BCLs, but the ratio was larger for atrial pacing (.77 +/- .05 SD) than for ventricular pacing (.60 +/- .05). Atropine (1 mg i.v.) was given to six patients. The drug did not affect the ERP-V in six of eleven determinations, prolonged ERP-V twice and shortened it slightly three times. Measurements were reproducible over an hour but varied at a given BCL when measured on separate days. Asymptomatic repetitive beating occurred in seven of 27 patients when the premature stimulus was within 20 msec of the ERP-V. The effective refractory period of the right ventricle in man can be determined reproducibly and with safety. Changes induced by various perturbations parallel results from in vitro single cell and myocardial studies.
Antigenic, antibiotic and phage receptor activity of proteins from Sh. boydii 15. (1975)

The analyzed strain of Sh. boydii 15 induced antibodies against the somatic antigen conjugate, as in most Shigella. Except for the proteinic carrier of the somatic antigen, only a few of the homologous proteinic determinants induced corresponding antibodies; these were illustrated with the help of a serum to proteins from Sh. sonnei. The proteins of Sh. boydii 15 displayed a wide range of antibiotic activity against Shigella, E. coli and Salmonella. Another aspect concerning the biological activities of the proteins isolated from Sh. boydii 15 was its temperate phage receptor activity. This activity was found as well in the free proteins as in the proteinic moiety of the somatic antigen.
On-column conductive coating for thermolabile columns used in capillary zone electrophoresis sheathless electrospray ionisation mass spectrometry (2000)

A simple and very mild approach for the application of a conductive layer for sheathless electrospray has been developed. A modified 'fairy dust' method is employed in which 2 microm gold particles are applied by a thin layer of silicone on shaped tips. This novel approach comprises fabrications at room temperature, under atmospheric pressure, and involves no etching, extensive cleaning or otherwise harsh conditions. With this approach, sheathless electrospray emitters have been fabricated from fused silica capillaries with chemically pre-modified inner walls and from heat-sensitive polypropylene hollow fibres. Long term stability for more than two weeks of continuous spraying has been achieved. Capillary zone electrophoresis/time-of-flight mass spectrometry demonstrates attomole sensitivity and no detectable band broadening. A comparison with a chromium-gold coated emitter in terms of chemical noise is made with continuous infusion experiments, showing no significant increase in background from the polymer involved.
Isolation and characterization of a functional cDNA encoding ICP0 from herpes simplex virus type 1 (1991)

The IE-0 gene of herpes simplex virus type 1 (HSV-1) contains two introns and encodes ICP0, a powerful transcriptional activator. We have isolated a cDNA clone that encodes ICP0 from a lambda gt10 cDNA library constructed from RNAs made from HSV-1-infected HeLa cells. DNA sequence analysis of this clone confirmed the predicted intron/exon boundaries (L. J. Perry, F. J. Rixon, R. D. Everett, M. C. Frame, and D. J. McGeoch, J. Gen. Virol. 67:2365-2380, 1986). Following transfection, a plasmid containing the cDNA copy of IE-0 directed the synthesis of ICP0, which was appropriately compartmentalized and distributed in the nucleus, as revealed by immunofluorescence. A transient expression assay was used to demonstrate that this cDNA copy retained the ability to transactivate the HSV-1 promoters for the IE-0 gene (an immediate-early gene), the thymidine kinase gene (an early gene), and the glycoprotein C gene (a late gene). The product of this cDNA clone cooperated with ICP4 to activate expression from the thymidine kinase gene promoter in a synergistic manner. The availability of a functional cDNA copy encoding ICP0 provides the opportunity to express this protein in vector systems that do not recognize eucaryotic donor and acceptor splicing signals to overexpress ICP0.

Task Scheduling in Wireless Sensor Networks (2010)

This paper discusses a scheduling algorithm for the sub-tasks of an application in a Wireless Sensor Network. With the next generation of sensor networks, task-based systems are needed to provide services to entities outside the network. Allocation of tasks on different wireless nodes must take into account energy constraints, compatibility of tasks to a given node or topology and must be in agreement with the purpose of the network. The problem described in this paper requires maximizing network lifetime and satisfying these allocation constraints. The solution proves to be correct though in some cases it can lead to algorithmic complexity, such that further work on an approximation algorithm might be indicated.
Runoff and Erosion as Affected by Corn Residue: Part I. Total Losses (1986)

ABSTRACT THE effects of varying rates of corn residue on runoff and erosion from a loess soil in southwestern Iowa were measured using a rainfall simulator. Consistent reductions in runoff, sediment concentration and soil loss resulted from increased residue application. Small amounts of surface cover produced substantial reductions in erosion. A regression equation relating surface cover to residue weight was obtained. Equations describing relative runoff, sediment concentration and soil loss as a function of surface cover were also developed using regression analysis.
