Libros de los recibidos en la compañía de Jesús en el Colegio de Salamanca (1930)

Microalgae are rich source of various bioactive molecules such as carotenoids, lipids, fatty acids, hydrocarbons, proteins, carbohydrates, amino acids, etc. and in recent Years carotenoids from algae gained commercial recognition in the global market for food and cosmeceutical applications. However, the production of carotenoids from algae is not yet fully cost effective to compete with synthetic ones. In this context the present review examines the technologies/methods in relation to mass production of algae, cell harvesting for extraction of carotenoids, optimizing extraction methods etc. Research studies from different microalgal species such as <i>Spirulina platensis, Haematococcus pluvialis, Dunaliella salina, Chlorella</i> sps., <i>Nannochloropsis</i> sps., <i>Scenedesmus</i> sps., <i>Chlorococcum</i> sps., <i>Botryococcus braunii</i> and <i>Diatoms</i> in relation to carotenoid content, chemical structure, extraction and processing of carotenoids are discussed. Further these carotenoid pigments, are useful in various health applications and their use in food, feed, nutraceutical, pharmaceutical and cosmeceutical industries was briefly touched upon. The commercial value of algal carotenoids has also been discussed in this review. Possible recommendations for future research studies are proposed.
Surface Modification of Silicone for Biomedical Applications Requiring Long-Term Antibacterial, Antifouling, and Hemocompatible Properties (2012)

Silicone has been used for peritoneal dialysis (PD) catheters for several decades. However, bacteria, platelets, proteins, and other biomolecules tend to adhere to its hydrophobic surface, which may lead to PD outflow failure, serious infection, or even death. In this work, a cross-linked poly(poly(ethylene glycol) dimethacrylate) (P(PEGDMA)) polymer layer was covalently grafted on medical-grade silicone surface to improve its antibacterial and antifouling properties. The P(PEGDMA)-grafted silicone (Silicone-g-P(PEGDMA)) substrate reduced the adhesion of Staphylococcus aureus , Escherichia coli , and Staphylococcus epidermidis , as well as 3T3 fibroblast cells by ≥90%. The antibacterial and antifouling properties were preserved after the modified substrate was aged for 30 days in phosphate buffer saline. Further immobilization of a polysulfobetaine polymer, poly((2-(methacryloyloxy)ethyl)dimethyl-(3-sulfopropyl)ammonium hydroxide) (P(DMAPS)), on the Silicone-g-P(PEGDMA) substrate via thiol-ene click reaction leads to enhanced antifouling efficacy and improved hemocompatibility with the preservation of the antibacterial property. Compared to pristine silicone, the so-obtained Silicone-g-P(PEGDMA)-P(DMAPS) substrate reduced the absorption of bovine serum albumin and bovine plasma fibrinogen by ≥80%. It also reduced the number of adherent platelets by ≥90% and significantly prolonged plasma recalcification time. The results indicate that surface grafting with P(PEGDMA) and P(DMAPS) can be potentially useful for the modification of silicone-based PD catheters for long-term applications.
Application of Self-Organizing Maps for clustering DJIA and NASDAQ100 portfolios (2003)

In this paper we apply the Self-Organized Map (SOM) method for clustering the DJIA and NASDAQ100 portfolios for determination of non-linear correlations between stocks. We represent the application of this method as alternative to ultrametric spaces method. We have found, that SOM method is more relevant and perspective for clustering ill-structured large databases and, in particular, NASDAQ100, where nonlinear processing of the large data samples is required.
A Time-Driven Workflow Scheduling Strategy for Reasoning Tasks of Autonomous Driving in Edge Environment (2019)

In various time-slots, the real-time reasoning tasks generated by autonomous vehicles are scheduled within tolerance time, which is the key problem to be solved in autonomous driving. Tasks are traditionally scheduled on the on-board unit (OBU), which leads to long completion time of tasks. Heuristic algorithms are widely used in task scheduling problems, which usually causes to premature convergence. Scheduling tasks in edge environment can effectively reduce completion time of tasks. In this paper, a workflow scheduling strategy was designed in edge environment according to the difference of reasoning tasks and the changes of edge nodes in various time-slots. Firstly, the model of Markov decision process (MDP) was built to describe the problem scenario, and the completion time of reasoning tasks was calculated by the workflow scheduling algorithm. Secondly, the Q-learning algorithm based on simulated anealing (SA-QL) was proposed to optimize the completion time of reasoning tasks. Finally, the performance of reinforcement learning algorithms based on simulated annealing (SA-RL) and particle swarm optimization (PSO) algorithm were comprehensively displayed from four perspectives: effectiveness, feasibility, exploration and convergence. The experimental results show that both SA-RL algorithms and PSO algorithm have good performance in feasibility and effectiveness. TD(0) algorithms have better performance of exploration and TD() algorithms have that of convergence.
Decreased uterine perfusion—a cause of infertility (1988)

There have been several causes of infertility attributed to gamete quality, congenital anatomical abnormalities and surgical complications. Published research into the reasons for failure of implantation of embryos has been confined to histochemical and histological studies of the endometrium. This paper presents preliminary data from an ongoing study to test the hypothesis that poor uterine perfusion is a cause of failure of implantation of embryos. It would follow that poor uterine perfusion is a cause of infertility. One-hundred-and-fifty-three patients who had been unsuccessful in conceiving despite three previous in-vitro fertilization attempts have been studied. Doppler ultrasound studies of the ascending branch of the uterine artery, during spontaneous ovarian cycles, revealed a poor mid-secretory uterine response in 48% of patients studied. Patients with poor mid-secretory uterine response were treated with orally administered hormone therapy to improve the mid-secretory uterine response prior to subsequent embryo replacement. The results of subsequent in-vitro fertilization therapy in patients with good uterine response and in women with improved uterine response after hormone therapy are presented. The numbers of patients in each group are insufficient for statistical analyses, but the trends observed support the hypothesis that poor uterine blood flow is a cause of infertility. Further evaluation is warranted.

Synthesis <i>in vitro</i> and Translocation of Apolipoprotein AI across Microsomal Vesicles (1981)

Apolipoprotein AI of rats has been synthesized in a cell-free wheat germ system and cotranslationally translocated into dog pancreas microsomal vesicles. Translocation is accompanied by cleavage of a signal sequence of 18 amino acid residues and is dependent on the recently purified signal recognition protein.
Hybrid multi/single layer array transducers for increased signal-to-noise ratio (1997)

In medical ultrasound imaging, two-dimensional (2-D) array transducers are necessary to implement dynamic focusing in two dimensions, phase correction in two dimensions and high speed volumetric imaging. However, the small size of a 2-D array element results in a small clamped capacitance and a large electrical impedance, which decreases the transducer signal-to-noise ratio (SNR). We have previously shown that SNR is improved using transducers made from multi-layer PZT, due to their lower electrical impedance. In this work, we hypothesize that SNR is further increased using a hybrid array configuration: in the transmit mode, a 10 Omega electronic transmitter excites a 10 Omega multi-layer array element; in the receive mode, a single layer element drives a high impedance preamplifier located in the transducer handle. The preamplifier drives the coaxial cable connected to the ultrasound scanner. For comparison, the following control configuration was used: in the transmit mode, a 50 Omega source excites a single layer element, and in the receive mode, a single layer element drives a coaxial cable load. For a 5x102 hybrid array operating at 7.5 MHz, maximum transmit output power was obtained with 9 PZT layers according to the KLM transmission line model. In this case, the simulated pulse-echo SNR was improved by 23.7 dB for the hybrid configuration compared to the control. With such dramatic improvement in pulse-echo SNR, low voltage transmitters can be used. These can be fabricated on integrated circuits and incorporated into the transducer handle.
REDUCTION IN THE DEVELOPMENT OF CERULEIN-INDUCED ACUTE PANCREATITIS BY TREATMENT WITH M40401, A NEW SELECTIVE SUPEROXIDE DISMUTASE MIMETIC (2004)

Oxidative stress plays an important role in the early stage of acute pancreatitis, as well as in the associated multiple organ injury. This study tests the hypothesis that M40401, a new superoxide dismutase mimetic, attenuates experimental acute pancreatitis. Intraperitoneal injection of cerulein in mice resulted in a severe, acute pancreatitis that was characterized by edema, neutrophil infiltration, tissue hemorrhage, and cell necrosis, as well as increases in the serum levels of amylase and/or lipase. The infiltration of the pancreatic tissue of these animals with neutrophils (measured as an increase in myeloperoxidase activity) was associated with expression of intercellular adhesion molecule-1, as well as signs of enhanced lipid peroxidation (e.g., increased tissue levels of malondialdehyde). Immunohistochemical examination demonstrated a marked increase in the staining (immunoreactivity) for nitrotyrosine and poly (ADP-ribose) polymerase in the pancreas of cerulein-treated mice. In contrast, the degree of pancreatic inflammation and tissue injury (histological score), the expression of intercellular adhesion molecule-1, the staining for nitrotyrosine and poly (ADP-ribose) polymerase, and lipid peroxidation were markedly reduced in pancreatic tissue sections obtained from cerulein-treated mice administered with M40401. These results confirm our hypothesis that superoxide anions play an important role in cerulein-mediated acute pancreatitis and support the possible clinical use of low-molecular-weight synthetic superoxide dismutase mimetics in those conditions that are associated with overproduction of superoxide.
Auxin Synergists in Rooting of Cuttings (1969)

Abstract Leafy cuttings of Eranthemum tricolor were treated with tannic acid, gallic acid, p‐hydroxybenzoic acid and salicylic acid at the concentrations of 1000, 100, 10 and 1 nig/1 for 24 hours, whereafter they were dipped quickly in a 1000 mg/l solution of IAA, IBA and NAA for ten seconds. None of the phenolics showed any root promoting effect when used singly. In combination with NAA and IBA tannic acid promoted rooting, however, with IAA there was no effect to be seen. Gallic acid also markedly increased the number of roots of cuttings treated with NAA and IBA. Even in this case there was no effect with IAA. Synergism was also recorded between p‐hydroxybenzoic acid and IAA or NAA but not with IBA. Salicylic acid greatly promoted rooting in combination with both IAA, IBA and NAA.

Immobilization of <i>Streptomyces flavochromogenes</i> pullulanase on tannic acid and TEAE–cellulose (1978)

Abstract Pullulanase was immobilized successfully by simple, inexpensive methods that may be useful for industrial application of this enzyme. A tannin–pullulanase(TP) complex was obtained by addition of tannic acid to the culture filtrate of thermophilic Streptomyces flavochromogenes . TP could be bound to TEAE–cellulose (TTCP). Immobilization in this manner took place with quantitative retention of activity. The immobilized enzymes were stable for more than six months. The optimum temperatures of the native enzyme and TP were both 50°C; that of TTCP was 45°C. In the presence of 5m M Ca 2+ , the activity of TTCP was increased approximately twofold and the optimum temperature was raised to 50–60°C. Pullulanase was not significantly eluted from TP or TTCP by NaCl Solution (0.1–0.5 M ).

Isolates of the Pasteuria penetrans Group from Phytoparasitic Nematodes in Bermudagrass Turf. (1990)

A survey was conducted between 1985 and 1989 of isolates of the Pasteuria penetrans group on phytoparasitic nematodes in bermudagrass (Cynodon spp.) turf in southern Florida. Six different isolates of the P. penetrans group were observed from five different species of phytoparasitic nematode hosts. Five of the bacterial isolates were different (P </= 0.01) in sporangium diameter, endospore width, and ratio of sporangium diameter to endospore width. All locations surveyed had one or more isolates present, suggesting that the Pasteuria penetrans group is widespread in its distribution in southern Florida. Three survey sites had high densities of Belonolaimus longicaudatus, with more than 60% of the host population encumbered with a large-spored isolate of Pasteuria (mean sporangium diameter = 6.10 mum). One of these sites was monitored for 16 months during which the proportion of nematodes encumbered with this Pasteuria isolate remained constant. Soil infested with this isolate was not suppressive to Pasteuria-free populations of B. longicaudatus grown on bermudagrass for 6 months after controlled soil inoculation. However, the proportion of spore-encumbered and parasitized B. longicaudatus after 6 months was 73%, which was similar to the 74% level observed at the field site. The uhrastructure of mature sporangia of the large-spored isolates of Pasteuria from B. longicaudatus and Hoplolaimus galeatus is described and compared with ultrastructural descriptions of P. penetrans sensu strictu and P. thornei from the literature. These B. longicaudatus and H. galeatus isolates of Pasteuria appear to be distinct from the known species and may warrant new species status.
Development and Testing of the MIT Acoustic Levitation Test Facilities (1991)

Two acoustic levitation test facilities have been developed for cloud physics experimentation. These facilities utilize acoustic standing wave energy to suspend both solid and liquid objects in a contact-free environment. In the still-air facility, the air in the test section is essentially motionless, whereas in the ventilated facility, a small vertical wind tunnel creates a steady flow through the test section. Temperature control is available in both facilities, and relative humidity can be adjusted in the still-air facility. It was observed that liquid samples deform, to first order, into shapes characteristic of freely failing raindrops when subjected to the acoustic standing wave. It was also determined that the presence of an acoustic field in the test section does not significantly affect molecular diffusion processes. Water-droplet freezing experiments were conducted in both facilities to demonstrate the capability to support samples during a change of phase.
The effect of adalimumab for induction of endoscopic healing and normalization of mucosal cytokine gene expression in Crohn's disease (2012)

Adalimumab induces accumulated complete endoscopic healing in 44% of patients after 52 weeks of therapy. Normalization of mucosal gene expression of cytokines does not occur in all patients with endoscopy-verified healed mucosa. Inclusion of normalized mucosal cytokine expression into the concept of mucosal healing could have an impact on long-term clinical outcome.
Schisandrin B Protects Against Tacrine- and Bis(7)-tacrine-Induced Hepatotoxicity and Enhances Cognitive Function in Mice (2002)

Intragastric administration (100-200 μmol/kg) of tacrine (THA) or bis(7)-THA could cause an acute and dose-dependent increase in plasma alanine aminotransferases activity in mice at 6 h after the drug administration. The increase in plasma enzyme activity was associated with an increase in hepatic malondialdehyde level, an indirect index of oxidative tissue damage. Pretreating mice with schisandrin B (Sch B), an active dibenzocyclooctadiene derivative isolated from the fruit of Schisandra chinensis, at a daily dose of 0.125-0.5 mmol/kg for 3 days protected against the THA/bis(7)-THA induced hepatic oxidative damage in a dose-dependent manner. Sch B treatment (0.025-0.5 mmol/kg/day × 5) also enhanced the passive avoidance-response in mice as assessed by the step-through task experiment. The ensemble of results suggests that Sch B may be useful for reducing the potential hepatotoxicity of THA/bis(7)-THA in anti-Alzheimer's therapy.
Crystallization on supercooled liquid in metallic Zr-Cu-Al glasses (1993)

Crystallization behaviors are isothermally examined on supercooled-liquid and amorphous states in metallic Zr-Al-Cu glasses using differential scanning calorimetry. On the basis of a kinetic analysis, it is examined that the crystallization occurs with a zero nucleation rate below the glass transition temperature Tg and a nearly steady-state nucleation rate above Tg. Arrhenius relation between effective time lag τ of nucleation and isothermal temperature appears as a curvature for alloys revealing a wide supercooled liquid region and a straight line for alloys without wider supercooled-liquid region. The differences are attributed to the effects of viscosity on nucleation at supercooled liquid. The difference in morphology during crystallization between amorphous and supercooled-liquid states was also confirmed.
Fiber-Bragg-grating sensor systems (1995)

Fiber-Bragg gratings (FBGs) are proving to be suitable for providing the basis of a range of new fiber devices for use in both the fiber communications and sensing areas.1 In the communications field, current attention is directed in particular on the development of grating-based WDM devices and dispersion compensators, whereas in sensing, grating-based sensors are being developed for multipoint structural-strain monitoring systems and other embedded sensor applications. In such sensing applications, the inherently wavelength-encoded output of Bragg gratings has a number of distinct advantages over other sensing schemes. One of the most important of these is that because the sensed information is encoded directly into wavelength, which is an absolute parameter, the output does not depend directly on the total light levels, losses in the connecting fibers and couplers, or source power. Consequently, the sensor can easily be operated intermittently without the need for recalibration or reinitialization of the system. The wavelength-encoded nature of the output also facilitates WDM by assigning each sensor to a different slice of the available source spectrum. Additionally, TDM can be used to augment the WDM to improve the multipoint sensing capabilities.
Copolymerization of ethylene and 1‐butene with highly active Ticl<sub>4</sub>/THF/Mgcl<sub>2</sub>, Ticl<sub>4</sub>/THF/Mgcl<sub>2</sub>/SiO<sub>2</sub>, and TiCl<sub>3</sub><sup>.</sup>1/3AlCl<sub>3</sub> catalysts (1994)

Abstract Highly active catalysts for copolymerization have been prepared by the precipitation of MgCl 2 /ToCl 4 complex with or without high surface area silica. Copolymerization of ethylene and 1‐butene has been tested by using the prepared catalysts at various concentrations of 1‐butene. The catalytic activities are 20–80 kg/g Ti h. The rate of copolymerization is strongly affected by the addition of 1‐butene. The decay rate of copolymerization is first order with respect to time. Analyses of copolymers with solvent extraction, DSC, IR, XRD, and NMR were performed. Ethylene reactivity ratio ( k 11 ) for TiCl 4 /MgCl 2 /THF catalyst is calculated to be about 26 by NMR spectrum. © 1994 John Wiley & Sons, Inc.
