An Antisense Transcript from within the <i>ptsG</i> Promoter Region in <i>Escherichia coli</i> (2010)

The ptsG gene, encoding the major glucose uptake system in Escherichia coli, is expressed from 2 promoters, a minor promoter p2 and a major downstream promoter p1. Transcription from both promoters is repressed by Mlc, and expression of p1 is activated by the cAMP/catabolite activator protein complex. Expression from p1 is also regulated post-transcriptionally in response to sugar stress via an sRNA, SgrS, which results in translational inhibition and mRNA degradation. Here, we demonstrate an additional level of complexity to the transcriptional pattern surrounding ptsG. A third promoter, p3, located between p1 and p2, was found to express a transcript antisense to ptsG. This promoter was detected by in vitro transcription and by RNA polymerase footprinting techniques and in vivo by S1 analysis and fusions with a lacZ reporter gene. Although the intrinsic strength of the p3 promoter was comparable to that of ptsG, it proved difficult to identify a full-length transcript. A faint transcript of greater than 400 nt could be detected. The transcript thus has more of the characteristics of a divergently expressed cryptic unstable transcript (CUT) than a prokaryotic sRNA.

On-line analyzer for Ni-Zn alloy electroplating bath. (1989)

In the production of Ni–Zn alloy electroplated steel sheets, the concentrations of Ni2+ and Zn2+ ions in the plating bath are necessary to be controlled. An automatic on-line analyzer has been developed for the process control. The on-line analysis system consists of a sampling system and an energy-dispersive X-ray fluorescence analyzer. The plating process solution is continuously supplied to the X-ray fluorescence analyzer through the sampling system form the plating trays. The concentrations of the Ni2+ and Zn2+ ions are determined from the intensities of Ni, Zn, Fe and S fluorescent lines. The intensities of the S and Fe lines are measured for interelement correction. The intensity of the S line is easily measured after a path in air with the energy-dispersive X-ray spectrometer. The S line is excited by chromium, and the Ni, Zn and Fe lines are by tungsten X-ray source, for obtaining a higher excitation efficiency. The analysis can be completed within 8 min. The analytical accuracies on the production line were 0.77 g/l for Ni2+ and 0.48 g/l for Zn2+ ion.
Dynamic Changes in Inhibin Messenger RNAs in Rat Ovarian Follicles During the Reproductive Cycle (1988)

The alterations in morphology and function of the ovarian follicle as it matures, ovulates, and becomes a corpus luteum are dramatic. A variety of steroid and polypeptide hormones influence these processes, and the ovary in turn produces specific hormonal signals for endocrine regulation. One such signal is inhibin, a heterodimeric protein that suppresses the secretion of follicle-stimulating hormone from pituitary gonadotrophs. Rat inhibin complementary DNA probes have been used to examine the levels and distribution of inhibin alpha-and beta A-subunit messenger RNAs in the ovaries of cycling animals. Striking, dynamic changes have been found in inhibin messenger RNA accumulation during the developmental maturation of the ovarian follicle.

[Spine deformity in Marfan's syndrome in childhood (author's transl)]. (1978)

The authors have studied twenty cases of spine deformity in children suffering from Marfan's syndrome. They describe the main features of the disease and point out the difficulty of accurate diagnosis in children with minor involvement. The deformities are those of a dysplastic scoliosis as shown by the frequency of vertebral inversion on the lateral view: dorso-lumbar kyphosis, decreased lumbar lordosis. The treatment should be surgical because of the danger of a fatal outcome without treatment. The incidence of non-union is high and the authors recommend systematic revision of the fusion double curve scolioses with a moderate kyphosis. In cases of severe kyphosis, the addition of anterior grafting is recommended.
Inducible Nitric Oxide Synthase Promoter Polymorphism Affords Protection Against Cognitive Dysfunction After Carotid Endarterectomy (2009)

We demonstrate an iNOS promoter polymorphism variant provides protection against moderate/severe cognitive dysfunction 1 month after CEA. Further, this protection appears to involve cognitive domains localized ipsilateral to the operative carotid artery.
Colony-Forming Cells in Culture and Colony-Stimulating Activity of the Urine and the Serum in a Case of Cyclic Neutropenia (1976)

A 22-year-old female with cyclic neutropenia was studied. Her bone marrow cells showed high colony-forming activity in soft agar through the cycle, though there were slight fluctuations in the number and the shape of colonies. On the other hand, the peak of urinary colong-stimulating activity (CSA) occurred at the neutropenic stage. The dialyzed serum showed two peaks of CSA, i.e., at the peak and the valley of the neutrophil count, although the undialyzed serum showed only one peak at the neutroenic stage. It is suggested on the basis of these data that humoral factors may play a role in maintaining the neutrophil cycle.
“Photoacoustics” and “acousto-optics”: listening to light and looking at sound (2005)

This paper briefly introduces the physics behind photoacoustic (listening to light) and acousto-optic (looking at sound) phenomena and describes several applications for fundamental or applied material research. The exploitation of a photoacoustic cell for the thermal characterization and depth profiling of liquid crystals is illustrated. It is illustrated that a photoacoustic cell can be used to study the magnetocaloric effect, and thus to investigate thermal and magnetic material properties. It is shown that optically excited and detected acoustic waves in materials can be very helpful to investigate their microscopic structure. In the impulsive stimulated scattering technique the mechanisms of converting light into thermal, acoustic, orientational and structural modes is exploited to simultaneously obtain information about the many physical properties of relaxing liquids.
Computing for the Underserved (invited paper) (2009)

[334 cases of salivary gland neoplasms seen at the Dentistry and Otorhinolaryngology Clinics of the University of Turin. II]. (1990)

Three hundred and thirty-four cases of salivary gland neoplasms are reported which were diagnosed by the Departments of Dentistry and Otolaryngology of the University of Turin. Data referring to patients under observation during the same period are compared. It is stressed that in order to obtain a statistically valid comparison of salivary gland neoplasms, the source of and chronological period relating to the sample group must be taken into consideration given the different statistical clinical methods adopted over the years by the two departments in question. The present study completes earlier research carried out by the same authors using this data.
Investigation of Drug-Cyclodextrin Complexes by a Phase-Distribution Method: Some Theoretical and Practical Considerations (2005)

The purpose of the study was to evaluate an octanol-water phase distribution method for investigation of drug/cyclodextrin (D/CD) complexes and to compare stability constant values obtained by this method to values obtained by the phase solubility method. A general equation for determination of 1 : 1 D/CD complex stability constant (K1 : 1) from the slope of a phase-distribution diagram (a diagram of the reciprocal of the apparent partition coefficient vs. the total CD concentration) was derived. The equation accounted for the possible inclusion of the organic solvent in the CD cavity and the gradual saturation of the CD binding with increasing concentration of the guest compound. This method was used to determine K1 : 1 for 2-hydroxypropyl-beta-cyclodextrin (HPbetaCD) complexes of hydrocortisone, prednisolone, diazepam, beta-estradiol and diethylstilbestrol. These values were comparable to K1 : 1 values determined by the phase-solubility method. The phase-distribution method could also be applied to determine stability constants for the neutral and ionic forms of the weakly acidic drugs, naproxen and triclosan and the weakly basic drug lidocaine. The phase-distribution method is a very versatile and fast method and has the advantage, compared to the phase-solubility method, that it only requires very small drug samples. Thus, this method would be suitable for screening of new drug candidates.
An approach for solving dynamic TSPs using neural networks (1991)

An approach for solving the D-TSP (dynamic traveling salesman problem) is discussed. The difference between a TSP and a D-TSP is that, in the latter, traveling costs between cities change according to the time of day. A neural network was applied to a D-TSP. This D-TSP was given a two-dimensional representation. With several maps, minimum cost tours were found by computer simulation using a Hopfield-Tank-type neural network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Strategies for Reservoir Characterization and Production Monitoring using Controlled Source Electromagnetic Data (2011)

Exploiting the fact that in a marine environment the source is continuously in action while towed behind a boat has improved CSEM capability as a direct resistor indicator. We have taken this synthetic source aperture concept one step further to show on numerically modeled data that uncertainties in source location and orientation are eliminated using a processing procedure called interferometry by multi-dimensional deconvolution. This procedure also eliminates the effects of the sea-surface. This procedure could work well for acquisition according to the present industry practice, under realistic uncertainties in receiver location and orientation, and realistic levels of noise. This is a data-driven procedure that requires properly recorded data. In case some data are not properly recorded due to receiver clipping, a hybrid model-driven data-driven approach must be used. We show some simple 2D examples to illustrate the concept of this procedure, including its drawbacks and advantages for characterization and monitoring purposes.
A Case Report of Colonic Perforative-Peritonitis in a Patient on CAPD (2006)

症例は63歳の女性で, 腎硬化症による慢性腎不全にて4年前より携帯式持続性腹膜透析 (以下, continuous ambulatory peritoneal dialysis: CAPD) を施行中であった. 下血を伴う腹痛にて本院受診した. 当初はCAPD腹膜炎と診断し保存的治療を開始したが症状の改善がないため, 消化管穿孔を疑い腹部CTを施行した. 同検査にて腹腔内free airや腹水貯留を認めるもCAPD液交換の際に流入したものとの鑑別ができず, また腹部所見も比較的乏しかったことから穿孔性腹膜炎の確定診断には至らなかった. しかし, 翌日のCAPD排液中に食物残査混入を認めたため, 穿孔性腹膜炎と確定診断され緊急開腹術を施行した. 開腹すると, 横行結腸に穿孔を認め汎発性腹膜炎を呈していた. 穿孔部結腸部分切除および人工肛門造設術を施行した.術後は敗血症から重度多臓器機能障害へ陥ったが, エンドトキシン吸着, 持続濾過透析, 血漿交換, ビリルビン吸着などを施行し救命しえた.
An automatic finite state machine synthesis using temporal logic decomposition (1991)

Since conventional methods to synthesize a finite state machine (FSM) assign binary codes to all the nonredundant states, they do not exploit delay latches which are sometimes effective in simplifying machine structure. The authors propose a novel method to synthesize an FSM by applying a time shift operation on both inputs and outputs of the FSM. Therefore, the FSM is decomposed into a smaller-scale FSM and two combinational logic circuits including the delay latches. One of the combinational logic circuits is attached to the input part of the FSM and the other is attached to its output part. The algorithm is evaluated for several benchmark examples of FSMs, from which it is concluded that the FSM can be synthesized with 5% less hardware by applying the proposed algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Ceramic-ceramic composites for dry sliding in closed tribosystems (1993)

Engineers have always dreamed of dry-running machine elements, i.e., moving parts that require no lubrication. However, because of heavy friction losses and wear, high-performance machinery can only maintain full operational reliability with the aid of sophisticated lubricants. The latest environmental legislation in Germany classifies liquid lubricants as pollutants requiring special disposal. Environmental legislation may someday require the elimination of lubricants. Preliminary results indicate that ceramic-ceramic composites may be a solution.
Elevated plasma viscosity in extreme hemodilution increases perivascular nitric oxide concentration and microvascular perfusion (2004)

We tested the hypothesis that high-viscosity (HV) plasma in extreme hemodilution causes wall shear stress to be greater than low-viscosity (LV) plasma, leading to enhanced production of nitric oxide (NO). The perivascular concentration of NO was measured in arterioles and venules and the tissue of the hamster chamber window model, subjected to acute extreme hemodilution, with a hematocrit (Hct) of 11% using Dextran 500 (n = 6) or Dextran 70 (n = 5) with final plasma viscosities of 1.99 +/- 0.11 and 1.33 +/- 0.04 cp, respectively. HV plasma significantly increased the periarteriolar, perivenular, and tissue NO concentration by 2.0, 1.9, and 1.4 times the control (n = 7). The NO concentration with LV plasma was not statistically different from control. Arteriolar shear stress was significantly increased in HV plasma relative to LV plasma in arterioles but not in venules. Aortic endothelial NO synthase (eNOS) protein expression was increased with HV plasma but not with LV plasma. There was a weak correlation between perivascular NO concentration and the locally calculated shear stress induced by the procedures, when blood viscosity was corrected according to Hct values previously determined in studies of microvascular Hct distribution. The finding that the periarteriolar and venular NO concentration in HV plasma was the same although arteriolar shear stress was significantly greater than venular shear stress maybe be due to differences in vessel wall metabolism between arterioles and venules and the presence of NO transport through the blood stream in the microcirculation. Results support the concept that in extreme hemodilution HV plasma maintains functional capillary density through a NO-mediated vasodilatation.

A simulation evaluation of optimistic replicated filing in mobile environments (1999)

Optimistic replication of data is becoming increasingly popular in mobile environments, but its performance and scaling characteristics are not well understood. This paper presents a simulation evaluation of optimistic replicated filing in a mobile environment. We first compare full and selective optimistic replication systems to capture the properties required for scaling. We then show that the presence of portable computers in optimistically replicated filing systems achieves a 60-percent cost reduction (e.g., computing resources) with only a 10-percent degradation of service quality (e.g., consistency of data perceived by users). This finding reveals certain similarities between the network disconnection interval and frequency of data synchronization. The research suggests new guidelines for design of optimistic replication systems.

THE DETERMINATION OF TITANIUM AS AN IMPURITY IN ZIRCONIUM AND ZIRCALOY (1957)

Titanium forms a yellow complex with hydrogen peroxide in a 1.5 to 3.5 N sulfuric acid solution. The color development is instantaneous and is stable for at least 24 hr. The maximum absorbance of the complex is at 410 mu. The method covers the determination of titanium as an impurity in zirconium and Zircaloy. The range of the method is from 10 to 100 ppm on a one gram sample basis. The principle interferences are vanadium and molybdenum. They must either be removed or a correction made for them. The interference of colored ions such as iron, nickel and chromium (III) is compensated for by the use of a portion of the sample solution, not treated with peroxide, in the reference cell. (auth)
