Trabeculotomía gonioasistida modificada, una alternativa quirúrgica mínimamente invasiva para el glaucoma (2018)

En una enfermedad como el glaucoma, considerada la segunda causa de ceguera en Cuba y en el mundo, el tratamiento quirúrgico ha experimentado una evolución sorprendente y se buscan opciones más sencillas, eficaces y con un posoperatorio tranquilo. En el departamento de Glaucoma del Instituto Cubano de Oftalmología se comenzó a realizar una modificación de la trabeculotomía gonioasistida y es de interés presentarla mediante la evolución posoperatoria a corto plazo de un caso clínico. Se trata de un paciente de 72 años de edad, con catarata y glaucoma descompensado, a pesar del tratamiento médico. Se presenta con 50 VAR de visión y presión intraocular de 26 mmHg. Se realizó cirugía combinada: facoemulsificación y trabeculotomía gonioasistida modificada. Se lograron cifras de presión intraocular de 18 mmHg y agudeza visual mejor corregida de 100 VAR a los 6 meses posoperatorios.
Dissecting plant secondary metabolism – constitutive chemical defences in cereals (2003)

Collectively plants synthesise a diverse array of secondary metabolites. Secondary metabolites are well known as agents that mediate pollination and seed dispersal. They may also act as chemical defenses that ward off pests and pathogens or suppress the growth of neighbouring plants. The ability to synthesise particular classes of secondary metabolite is commonly restricted to selected plant groups, and the evolution of different pathways in distinct plant lineages is likely to have been key for survival and for the generation of diversity at the organism level. An understanding of the evolution of secondary metabolism requires the characterisation of enzymes and genes for complete pathways in a broad range of plants in addition to the two model species, Arabidopsis thaliana and rice. Tracing the ancestry of the pathway components can then unravel the chain of events that led to the creation of individual pathways. This review summarises progress that has been made in the dissection of the pathways for constitutive chemical defences in cereals, namely saponins and benzoxazinoids.

On Bacteriocin Delivery Systems and Potential Applications (2014)

Bacteriocins are antimicrobial peptides produced by a variety of bacteria. These peptides can act as antibiotic synergists or alternatives to enhance the therapeutic effects of current infection treatments and decrease the prevalence of resistant strains. Two bacteriocins, namely nisin and pediocin PA-1, are currently being used by the food industry; however, the introduction of these and others into the biomedical industry, and further development of food applications, have been challenged by the slow development of reliable delivery systems. For bacteriocins, these systems rely on novel and pre-existing technologies. Many essential variables need to be accounted for to formulate successful delivery methods. In this review, documented and potential bacteriocin delivery systems are examined, with special attention paid to how those systems are being implemented in the food and medical industries.

Dupin Cyclide Blends Between Quadric Surfaces for Shape Modeling (2004)

Abstract We introduce a novel method to define Dupin cyclide blends between quadric primitives. Dupin cyclides are non‐spherical algebraic surfaces discovered by French mathematician Pierre‐Charles Dupin at the beginning of the 19th century. As a Dupin cyclide can be fully characterized by its principal circles, we have focussed our study on how to determine principal circles tangent to both quadrics being blended. This ensures that the Dupin cyclide we are constructing constitutes a G 1 blend. We use the Rational Quadratic Bézier Curve (RQBC) representation of circular arcs to model the principal circles, so the construction of each circle is reduced to the determination of the three control points of the RQBC representing the circle . In this work, we regard the blending of two quadric primitives A and B as two complementary blending operations: primitive A‐cylinder and cylinder‐primitive B; two Dupin cyclides and a cylinder are then defined for each blending operation. In general the cylinder is not useful and may be reduced to a simple circle. A complete shape design example is presented to illustrate the modeling of Eurographics'04 Hugo using a limited number of quadrics combined using Dupin cyclide blends .

Electrocatalytic and Solar‐Driven CO<sub>2</sub> Reduction to CO with a Molecular Manganese Catalyst Immobilized on Mesoporous TiO<sub>2</sub> (2016)

Electrocatalytic CO2 reduction to CO was achieved with a novel Mn complex, fac-[MnBr(4,4'-bis(phosphonic acid)-2,2'-bipyridine)(CO)3 ] (MnP), immobilized on a mesoporous TiO2 electrode. A benchmark turnover number of 112±17 was attained with these TiO2 |MnP electrodes after 2 h electrolysis. Post-catalysis IR spectroscopy demonstrated that the molecular structure of the MnP catalyst was retained. UV/vis spectroscopy confirmed that an active Mn-Mn dimer was formed during catalysis on the TiO2 electrode, showing the dynamic formation of a catalytically active dimer on an electrode surface. Finally, we combined the light-protected TiO2 |MnP cathode with a CdS-sensitized photoanode to enable solar-light-driven CO2 reduction with the light-sensitive MnP catalyst.

Reminiscences of a Trip to Cedar Breaks (1966)

Reflecting on a time when automobile and horse-drawn travel overlapped, the Arizona State University president shares in this personal essay his memories of Mormon childhood growing up in southern Utah, particularly his reminiscences of taking trips up Parowan Canyon to get out of the summer heat. He describes unsuccessful attempts to summit Brian Head Peak in a Ford touring car, the trip being interrupted by herds of sheep blocking the road, and he reflects on a camping trip made by covered wagon. He compares his awe at seeing Cedar Breaks for the first time to Brigham Young’s inspiration when he declared, “This is the place,” upon first seeing the Salt Lake Valley.

Timing Influenced Layout Design (1985)

We present a new approach to the automatic layout design for VLSI chips which incorporates timing information to influence the placement and wiring processes. This approach is an extension of the hierarchical layout method, in which placement and wiring are performed simultaneously [1]. We add a third phase of timing to the hierarchy, without affecting the computational complexity of the basic algorithm. Prior to the physical design, timing analysis is performed using statistical estimates for the unknown parameters; namely the lengths of interconnecting wires. The output of this analysis includes a measure for each net that indicates the degree of its contribution to the timing problem. This set of measures is used to bias the placement at the highest level of the hierarchy. Since wiring is performed after each level of partitioning, lengths of interconnecting nets among the partitions become available. These data are used to update the timing information that bias the design. Preliminary results show that, while delays due to interconnections are reduced, wireability of the chip does not deteriorate.
Assessment of Photodynamic Destruction of <i>Escherichia coli</i> O157:H7 and <i>Listeria monocytogenes</i> by Using ATP Bioluminescence (2003)

Antimicrobial photodynamic therapy was shown to be effective against a wide range of bacterial cells, as well as for fungi, yeasts, and viruses. It was shown previously that photodestruction of yeast cells treated with photosensitizers resulted in cell destruction and leakage of ATP. Three photosensitizers were used in this study: tetra(N-methyl-4-pyridyl)porphine tetratosylate salt (TMPyP), toluidine blue O (TBO), and methylene blue trihydrate (MB). A microdilution method was used to determine MICs of the photosensitizers against both Escherichia coli O157:H7 and Listeria monocytogenes. To evaluate the effects of photodestruction on E. coli and L. monocytogenes cells, a bioluminescence method for detection of ATP leakage and a colony-forming assay were used. All tested photosensitizers were effective for photodynamic destruction of both bacteria. The effectiveness of photosensitizers (in microgram-per-milliliter equivalents) decreased in the order TBO > MB > TMPyP for both organisms. The MICs were two- to fourfold higher for E. coli O157:H7 than for L. monocytogenes. The primary effects of all of the photosensitizers tested on live bacterial cells were a decrease in intracellular ATP and an increase in extracellular ATP, accompanied by elimination of viable cells from the sample. The time courses of photodestruction and intracellular ATP leakage were different for E. coli and L. monocytogenes. These results show that bioluminescent ATP-metry can be used for investigation of the first stages of bacterial photodestruction.
Intravenous immune globulin in chronic lymphocytic leukaemia. (1994)

The most common complication of chronic lymphocytic leukaemia (CLL) is infection, which occurs mainly in advanced stages of disease or in those patients with hypogammaglobulinaemia. Intravenous immune globulin (IVIG) has been shown to be a useful prophylactic therapy against infections in such patients. A randomized, double-blind study on 36 patients receiving either 500 mg/kg or 250 mg/kg IVIG every 4 weeks was undertaken to determine the dose regimen required. There was no significant difference in the two treatment groups and we found that CLL patients were equally protected with low-dose IVIG.

Ewing's sarcoma family tumors are sensitive to tumor necrosis factor-related apoptosis-inducing ligand and express death receptor 4 and death receptor 5. (2001)

In this study, we investigated the sensitivity of Ewing's sarcoma family tumors (ESFTs) of children and adolescents to the tumor necrosis factor-related apoptosis-inducing Ligand (TRAIL). TRAIL binds to death receptors (DRs) DR4, DR5, DcR1, and DcR2. Either DR4 or DR5 can induce apoptosis, whereas DcR1 and DcR2 are considered inhibitory receptors. Nine of 10 ESFT cell lines, including several that were Fas resistant, underwent apoptosis with TRAIL through activation of caspase-10, capase-8 (FLICE), caspase-3, and caspase-9. In contrast to the Fas signaling pathway, caspase-10, but not caspase-8 or the Fas-associated death domain-containing molecule, was recruited to the TRAIL receptor-associated signaling complex. We found that 9 of 10 ESFT cell lines expressed both DR4 and DR5 by Western blotting, whereas the TRAIL-resistant line expressed only DR4. However, DR4 was absent from the cell surface in the resistant and two additional lines (three of five tested lines), suggesting that it may have been nonfunctional. On the contrary, DR5 was located on the cell surface in all four sensitive lines tested, being absent only from the cell surface of the resistant line that was also DR5-negative by Western blotting. In agreement with these findings, the resistance of the line was overcome by restoration of DR5 levels by transfection. Levels of DcR1 and DcR2 or levels of the FLICE-inhibitory protein (FLIP) did not correlate with TRAIL resistance, and protein synthesis inhibition did not sensitize the TRAIL-resistant line to TRAIL. Because these data suggested that sensitivity of ESFTs to TRAIL was mainly based on the presence of DR4/DR5, we investigated the presence of these receptors in 32 ESFT tissue sections by immunohistochemistry. We found that 23 of 32 tumor tissues (72%) expressed both receptors, 8 of 32 (25%) expressed one receptor only, and 1 was negative for both. Our finding of wide expression of DR4/DR5 in ESFT in vivo, in combination with their high sensitivity to TRAIL in vitro and the reported lack of toxicity of TRAIL in mice and monkeys, suggests that TRAIL may be a novel effective agent in the treatment of ESFTs.
Eye Movement Patterns in Dyslexic Children (1980)

In this study we recorded eye movements during reading tasks for five dyslexic children and two controls. The subjects had vertical as well as horizontal eye position monitored with an infrared recording technique and performed a symbol-simulated reading task. We demonstrated the importance of both the symbol simulation and the vertical monitoring in evaluating the eye-movement patterns in dyslexics. Without the symbols, motor and comprehension defects cannot be distinguished. Without vertical eye position information, the horizontal eye-movement pattern is not properly interpretable.
Diffusion of autoinducer is involved in regulation of the Vibrio fischeri luminescence system (1985)

The enzymes for luminescence in Vibrio fischeri are induced by the accumulation of a species-specific metabolite (autoinducer) in the culture medium. Tritium-labeled autoinducer was used to study the mechanism of autoinduction. When 3H-autoinducer was added to suspensions of V. fischeri or Escherichia coli, cellular concentrations equaled external concentrations. For V. fischeri, equilibration of 3H-autoinducer was rapid (within 20 s), and greater than 90% of the cellular tritium remained in unmodified autoinducer. When V. fischeri or E. coli cells containing 3H-autoinducer were transferred to autoinducer-free buffer, 85 to 99.5% of the radiotracer escaped from the cells, depending on the strain. Concentrations of autoinducer as low as 10 nM, which is equivalent to 1 or 2 molecules per cell, were sufficient for induction, and the maximal response to autoinducer occurred at about 200 nM. If external autoinducer concentrations were decreased to below 10 nM after induction had commenced, the induction response did not continue. Based on this study, a model for autoinduction is described wherein autoinducer association with cells is by simple diffusion and binding of autoinducer to its active site is reversible.
