Mutant of <i>Escherichia coli</i> Exhibiting a Cold-sensitive Phenotype for Growth on Lactose (1969)

As part of a study on the effect of low temperature on cellular regulatory processes, a class of lactose-negative mutants of Escherichia coli K-12 was isolated which could use lactose as a sole carbon and energy source at 37 C, but which could not use this sugar at 20 C. The lactose operon of the mutants functioned normally at 20 C. Galactose exhibited a strong inhibitory effect on growth, especially at 20 C. Growth of the mutants on glycerol was stopped at 20 C and slowed considerably at 37 C if galactose was added to the medium. Making the mutants galactose-positive eliminated the cold sensitivity of lactose utilization. One mutant was shown to be galactose-1-phosphate uridyl transferase-negative, galactose-kinase heat-sensitive, and uridine diphosphate-galactose-4-epimerase-positive. It is postulated that the mutant is able to phosphorylate galactose at 20 C (if only at a very low rate), but lacking transferase it is poisoned by the accumulation of galactose-1-phosphate. At 37 C, galactokinase is nonfunctional and the mutant grows on the glucose moiety of lactose.
Slow propagation of electromagnetic waves in a dielectric slab waveguide with a left-handed material substrate (2006)

The dispersion properties of the guided modes propagating along a dielectric slab waveguide with a left-handed material substrate are studied. It is shown that both the oscillating and surface modes can propagate very slowly along such a waveguide if the thickness of the core layer is chosen appropriately. The propagation speed of the guided waves can even approach zero and this slow propagation is illustrated with an finite-difference time-domain simulation in a tapered waveguide. The influence of the material loss on the slow propagation is also discussed.
Compressed Imaging With a Separable Sensing Operator (2009)

Compressive imaging (CI) is a natural branch of compressed sensing (CS). Although a number of CI implementations have started to appear, the design of efficient CI system still remains a challenging problem. One of the main difficulties in implementing CI is that it involves huge amounts of data, which has far-reaching implications for the complexity of the optical design, calibration, data storage and computational burden. In this paper, we solve these problems by using a two-dimensional separable sensing operator. By so doing, we reduce the complexity by factor of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> for megapixel images. We show that applying this method requires only a reasonable amount of additional samples.
Spherical gridding in seismic imaging (2007)

We introduce a new gridding method to interpolate the image function on the spherical or ellipsoidal surface. The function is specified at discrete control points, and the proposed method allows one to obtain a continuous distribution of the image function through the curved surface. To solve the problem, we simulate elastic bending of a thin shell reinforced by springs. The springs are located at the control points. We do not require an exact match between the interpolated function and the given values at the control points, and this makes it possible to get an optimum balance between accuracy and smoothness. The method is a key component in angle domain imaging, in particular in cases where the angle domain is not fully illuminated.
Crowdsourcing & Multimedia (2016)

This paper summarizes some information about a 4 hours short course presented by the authors during the WebMedia'16. Our short course aims to present the concept of crowdsourcing and empower participants to implement this model of production in various activities linked with Multimedia and Web Systems, such as annotation, generation, summarization, synchronization, recommendation, retrieval, presentation and evaluation of the content quality. The idea behind crowdsourcing is to take advantage of the processing power of a multitude of employees to accomplish tasks that are "difficult for a computer", but which are apparently "simple to human intelligence". Describing the contents of an image or a video as inappropriate is an example of such difficult task, because the description of the problem by means of algorithms and automated techniques applied to parameters of this content is very complex and inaccurate. Another complex task is the subjective assessment of the quality of video encoders, the results depend on the user's perception and not only on parameters such as signal-to-noise ratio, resolution or frame rate. The crowdsourcing model tends to provide reliable results for this and other problems related to Multimedia and Web Systems. The additional content support for this short course brings the fundamental concepts of crowdsourcing, a discussion of suitable scenarios for their use within the multimedia and examples of practical use of the concept in real-world scenarios.
Enhancement of Remote Sensing for Mobile Source Nitric Oxide (1996)

A nitric oxide (NO) detector was developed and integrated into the original carbon monoxide (CO) and hydrocarbon (HC) remote sensing system developed by the University of Denver. The system is capable of measuring the CO, HC, and NO exhaust emissions of thousands of on-road vehicles per day. Analysis of a typical field measurement in Denver shows CO, HC, and NO emissions have similar statistics which can be well represented by a gamma distribution. The fraction of NO high emitters tends to increase with age, apparently arising from deterioration of the emissions control system. This paper presents the inverse relationship between NO and either CO or HC emission.
Chemistry and antibacterial activity of nitrobenzofurans (1976)

Thirteen 2-methylbenzofurans were synthesized and their antibacterial activity was investigated. 2-Methyl-3-nitrobenzofuran and analogs containing 7-NO2, 5-NO2, 7-Br, 7-CONH2, and 7-CF3 substituents are bacteriostatic. The spectrum of activity of these compounds is similar to nitrofurazone; however, a strain of E. coli Br which has increased resistance to nitrofurazone did not show increased resistance to 3,7-dinitro-2-methylbenzofuran (1). The 3-nitro-2-methylbenzofurans are labile in solution (T1/2 0.8-3.5 hr at 37 degrees, pH 7.0). The solvolysis product of 1 was identified as alpha,6-dinitro-o-cresol (15). The 3-nitrobenzofurans are more potent in minimal media than in Penassay broth. This greater potency can be abolished by addition of casamino acids and tryptophan to the minimal media.
Design of Alternative Purification Processes for Potassium Sulfate (2005)

Experimental data on the solubility and particle size distribution were obtained for use in the conceptual design of a drowning-out crystallization process for the purification of potassium sulfate in an aqueous feed. This process is compared to the conventional evaporative crystallization process in terms of equipment cost, energy requirement, process flows, and product crystal quality.
Transformation of<i>Lactobacillus casei</i>by electroporation (1987)

Electroporation has been used to introduce DNA into both eucaryotic and procaryotic cells. Since current methods for the transfection and transformation of lactobacilli using protoplasts are slow, inefficient, and inconsistent, we evaluated electroporation as a simple alternative. In initial experiments, PL-1 phage DNA (40 kb) was transfected into untreated cells of Lactobacillus casei by electroporation. Approximately 50% of the CFU survived pulses of 5000 V/cm at 25 μF; conditions found to be optimal for the transfection process. The β-galactosidase-encoding plasmid, pLZ15 (28 kb), and the vectors pSA3 (Emr), pLP825 (Cmr) and pNZ12 (Cmr) transformed L. casei at efficiencies of 1.1–8.5 × 104 transformants/μg DNA. Plasmid DNA isolated from pNZ12 containing transformants was used to retransform L. casei and was indistinguishable from authentic preparations of pNZ12 by gel electrophoretic analysis.
New Switchable Mirror Based on Magnesium–Niobium Thin Film (2006)

We found that palladium-capped magnesium–niobium alloy thin films show a good optical switching property when they are exposed to a hydrogen-containing atmosphere. A switchable mirror based on a magnesium–niobium thin film was prepared on a glass substrate by cosputtering of Mg and Nb targets. Mg1-xNbx thin films with a 4 nm Pd overlayer can be switched reversibly between shiny mirror and transparent states with the reversible uptake of 4% hydrogen gas at room temperature. In the hydride (transparent) state, they are almost color neutral.

2-aryl-3-phenylamino-4,5-dihydro-2H-benz[g]indazoles with antiarrhythmic and local anaesthetic activities. (1995)

The synthesis of novel 2-aryl-3-phenylamino-4,5-dihydro-2H-benz[g]indazoles 4a-f, starting from N-phenyl-3,4-dihydro-1(2H)-oxonaphthalene-2-carbothioamide and the proper arylhydrazines, is described. Title compounds were evaluated for antiinflammatory, analgesic, antipyretic, antiarrhythmic, hypotensive, local anaesthetic and platelet antiaggregating activities; some of them showed an appreciable antiarrhythmic activity in rats and a good level of infiltration anaesthesia in mice.
A systematic review on prognostic indicators of acute on chronic liver failure and their predictive value for mortality (2012)

The ambiguity and variability in the definition of ACLF and in its predictive indicators hampers comparability among studies. There is a need for a single uniform definition of ACLF. Also absence of a gold standard is an obstacle to render one indicator superior to another. The age, hepatic encephalopathy, model for end-stage liver disease score, total bilirubin and International normalized ratio (prothrombin time) appeared to be promising candidates for evaluation in future studies. The result of this review may be useful as a starting point in developing a standard list of indicators for clinical outcome that concur with the clinicians' subjective views on prognosis in ACLF.
Parastomal Hernia Repair and Reinforcement: The Role of Biologic and Synthetic Materials (2014)

Parastomal hernia is a prevalent problem and treatment can pose difficulties due to significant rates of recurrence and morbidities of the repair. The current standard of care is to perform parastomal hernia repair with mesh whenever possible. There exist multiple options for mesh reinforcement (biologic and synthetic) as well as surgical techniques, to include type of repair (keyhole and Sugarbaker) and position of mesh placement (onlay, sublay, or intraperitoneal). The sublay and intraperitoneal positions have been shown to be superior with a lower incidence of recurrence. This procedure may be performed open or laparoscopically, both having similar recurrence and morbidity results. Prophylactic mesh placement at the time of stoma formation has been shown to significantly decrease the rates of parastomal hernia formation.
Studies on immunological paralysis. I. A consideration of macrophage involvement in the induction of paralysis and immunity by type II pneumococcal polysaccharide. (1969)

Induction of paralysis with SII in mice was slightly facilitated by administration in ten injections during 5 weeks as compared with the equivalent total dose in a single injection. No improvement was afforded by repeated injection with regard to the degree of immunization. Mice which had been hyperimmunized with type II pneumococcal vaccine were relatively resistant to the induction of paralysis with SII, while animals which had been immunized with purified SII were as readily or more readily made tolerant than were normal control animals. SII in particulate form (complexed with methylated bovine serum albumin) (SII–MBSA) was indistinguishable from soluble SII with regard to its immunogenicity and capacity to induce paralysis. Paralysis could be induced by the intravenous injection of normally paralytogenic doses of either SII–MBSA or soluble SII into splenectomized mice. Such mice were no less readily paralysed than normal animals. Polysaccharide still circulating in mice 10 days after injection of paralysing doses (100–500 μg) of SII was strongly immunogenic on transfer of serum to normal recipients. Five hundred rad whole body irradiation 24 hr before injection of varying doses of SII failed to lower the paralysis threshold. It is concluded that SII does not exist in distinct immunogenic (particulate) and paralytogenic (soluble) forms; that the macrophage appears to play no essential role in the initiation phase of an immune response to SII; and that the major portion of SII which is phagocytosed is ultimately involved in the induction of paralysis. The apparent anomaly of the latter feature could be explained by a continual release of phagocytosed SII from macrophages by exocytosis.
Optimization of Allylic Oxidation of (1S,3R,8R)‐2,2‐Dichloro‐3,7,7,10‐tetramethyltricyclo[6,4,0,0<sup>1,3</sup>]dodec‐9‐ene (2004)

Abstract The allylic oxidation of (1S,3R,8R)‐2,2‐dichloro‐3,7,7,10‐tetramethyltricyclo[6,4,0,01,3]dodec‐9‐ene into the corresponding enone with N‐bromosuccinimide (NBS), CrO3 and t‐BuOOH has been studied. A good yield and high selectivity were obtained in the presence of t‐BuOOH and a copper catalyst.
Daily muscle stretching enhances blood flow, endothelial function, capillarity, vascular volume and connectivity in aged skeletal muscle (2018)

Mechanical stretch stimuli alter the morphology and function of cultured endothelial cells; however, little is known about the effects of daily muscle stretching on adaptations of endothelial function and muscle blood flow. The present study aimed to determine the effects of daily muscle stretching on endothelium-dependent vasodilatation and muscle blood flow in aged rats. The lower hindlimb muscles of aged Fischer rats were passively stretched by placing an ankle dorsiflexion splint for 30 min day<sup>-1</sup> , 5 days week<sup>-1</sup> , for 4 weeks. Blood flow to the stretched limb and the non-stretched contralateral limb was determined at rest and during treadmill exercise. Endothelium-dependent/independent vasodilatation was evaluated in soleus muscle arterioles. Levels of hypoxia-induced factor-1α, vascular endothelial growth factor A and neuronal nitric oxide synthase were determined in soleus muscle fibres. Levels of endothelial nitric oxide synthase and superoxide dismutase were determined in soleus muscle arterioles, and microvascular volume and capillarity were evaluated by microcomputed tomography and lectin staining, respectively. During exercise, blood flow to plantar flexor muscles was significantly higher in the stretched limb. Endothelium-dependent vasodilatation was enhanced in arterioles from the soleus muscle from the stretched limb. Microvascular volume, number of capillaries per muscle fibre, and levels of hypoxia-induced factor-1α, vascular endothelial growth factor and endothelial nitric oxide synthase were significantly higher in the stretched limb. These results indicate that daily passive stretching of muscle enhances endothelium-dependent vasodilatation and induces angiogenesis. These microvascular adaptations may contribute to increased muscle blood flow during exercise in muscles that have undergone daily passive stretch.
Tumor Suppressor p53 Protein Is a New Target for the Metastasis-associated Mts1/S100A4 Protein (2001)

A physical and functional interaction between the Ca(2+)-binding protein Mts1 (S100A4) and the tumor suppressor p53 protein is shown here for the first time. We demonstrate that Mts1 binds to the extreme end of the C-terminal regulatory domain of p53 by several in vitro and in vivo approaches: co-immunoprecipitation, affinity chromatography, and far Western blot analysis. The Mts1 protein in vitro inhibits phosphorylation of the full-length p53 and its C-terminal peptide by protein kinase C but not by casein kinase II. The Mts1 binding to p53 interferes with the DNA binding activity of p53 in vitro and reporter gene transactivation in vivo, and this has a regulatory function. A differential modulation of the p53 target gene (p21/WAF, bax, thrombospondin-1, and mdm-2) transcription was observed upon Mts1 induction in tet-inducible cell lines expressing wild type p53. Mts1 cooperates with wild type p53 in apoptosis induction. Our data imply that the ability of Mts1 to enhance p53-dependent apoptosis might accelerate the loss of wild type p53 function in tumors. In this way, Mts1 can contribute to the development of a more aggressive phenotype during tumor progression.
Modeling of electric vehicle loads for power flow analysis based on PSAT (2016)

This paper proposes the modeling of electric vehicle(EV) loads for power flow analysis based on User Define Models (UDMs) in power system analysis toolbox (PSAT) programming, According to the development of EV technology especially motor controller and battery, the EV has totally designed and made for using in city area as small city cars. To study the performance of EV, this aims to present the model of EV loads for using to solve power flow analysis in the real power system. EV load is modeled as the function box equivalent on PSAT that can connect to the single line diagram of power system model. The IEEE 14 bus system is selected for simulating the performance of EV and charging station which compared between PQ load base case and EV load. The simulation result showed that the EV load was installed at bus No.14. The rated power of EV load was increased from 5.0 p.u. to 79 p.u. This proposed EV load model can be used to solve the power flow analysis with continuation power flow (CPF) method. The EV load model is directly effected to voltage stability margin when the EV load increased. This study can be verified that proposed EV load can use to study the EV load in the future works.

Nuevas sensibilidades y sujetos: un viejo sujeto, un nuevo sentido. (1998)

Las profundas transformaciones culturales y sociales de este fin de siglo han ido modelando nuevos sujetos sociales y re-definiendo viejos sujetos constituidos por la modernidad: es el caso de la ninez. Conforme a los procesos globales, en ciertos sentidos se observa una tendencia de medievalizacion de la ninez, que a modo de espiral dialectica retorna a algunas de sus formas culturales, resignificadas en el contexto de la cultura mediatica y la incertidumbre ante la perdida de utopias.
Las practicas culturales actuales de los ninos, en particular de los ninos latinoamericanos, evidencian un quiebre con las practicas sociales asignadas a la infancia en el proyecto moderno, el cual consideramos esta provocado fundamentalmente por la cultura mediatica y por las condiciones de vida. A lo largo del siglo las condiciones de vida de los ninos latinoamericanos han evidenciado un deterioro creciente, modificandose el papel de estos en la economia familiar, puesto que ha aumentando el porcentaje de familias que procuran su supervivencia mediante diversas formas de trabajo infantil.
