Optical rotatory dispersion and circular dichroism studies of copoly(propyl‐L‐aspartate‐benzyl‐L‐aspartate) (1984)

Abstract Copoly(propyl‐ L ‐aspartate‐benzyl‐ L ‐aspartate)s with various compositions were synthesized by propylation of a parent poly(β‐benzyl‐ L ‐Aspartate). The variation of helix sense of copolyaspartate obtained against a degree of propylation and temperature was examined by optical rotatory dispersion and circular dichroism method. Copolyaspartate of propylation less than about 70% is in a left‐handed α helix conformation and its Moffitt parameter b 0 and molecular ellipticity [θ] 222 decreased gradually with increasing propylation. On the other hand, a different temperature dependence of b 0 and [θ] 222 was observed for copolyaspartate of propylation more than about 80%, i.e., the reversible transition of the helix sense from right‐ to left‐handed α helix took place by temperature increasing. These features were basically similar to the variation in helix sense of copoly(ethyl‐ L ‐aspartate‐benzyl‐ L ‐aspartate), although a slight difference was seen for copoly(propyl‐ L ‐aspartate‐benzyl‐ L ‐aspartate). The thermodynamic treatment indicating larger entropy of right‐handed α helix suggests much mobile side chain of the right‐handed α helix than the left handed one.

Genetic risk of dementia modifies the impact of obesity on limbic white matter and spatial navigation behavior in cognitively healthy adults (2019)

Abstract A family history (FH) of dementia, APOE -ε4 genotype, and obesity are major risk factors for developing Alzheimer’s disease but their combined effects on the brain and cognition remain elusive. We tested the hypothesis that these risk factors affect apparent white matter (WM) myelin and cognition including spatial navigation and processing speed in 166 asymptomatic individuals (38-71 years). Microstructure in temporal [fornix, parahippocampal cingulum, uncinate fasciculus], motor and whole-brain WM was assessed with myelin-sensitive indices from quantitative magnetization transfer [macromolecular proton fraction (MPF)] and axon density from diffusion imaging. Individuals with the highest genetic risk (FH+ and APOE -ε4) compared to those with FH+ alone showed obesity-related reductions in MPF and axon density in the right parahippocampal cingulum. No effects were present for those without FH. Furthermore, FH modulated obesity-related effects on spatial navigation behaviour. In summary, an individual’s genetic dementia risk influenced the impact of obesity on WM myelin and cognition.
Smad ubiquitination regulatory factor-2 controls gap junction intercellular communication by modulating endocytosis and degradation of connexin43 (2012)

Gap junctions consist of arrays of intercellular channels that enable adjacent cells to communicate both electrically and metabolically. Gap junction channels are made of a family of integral membrane proteins called connexins, of which the best-studied member is connexin43. Gap junctions are dynamic plasma membrane domains, and connexin43 has a high turnover rate in most tissue types. However, the mechanisms involved in the regulation of connexin43 endocytosis and transport to lysosomes are still poorly understood. Here, we demonstrate by live-cell imaging analysis that treatment of cells with 12-O-tetradecanoylphorbol 13-acetate (TPA) induces endocytosis of subdomains of connexin43 gap junctions. The internalized, connexin43-enriched vesicles were found to fuse with early endosomes, which was followed by transport of connexin43 to the lumen of early endosomes. The HECT E3 ubiquitin ligase smad ubiquitination regulatory factor-2 (Smurf2) was found to be recruited to connexin43 gap junctions in response to TPA treatment. Depletion of Smurf2 by small interfering RNA resulted in enhanced levels of connexin43 gap junctions between adjacent cells and increased gap junction intercellular communication. Smurf2 depletion also counteracted the TPA-induced endocytosis and degradation of connexin43. Collectively, these data identify Smurf2 as a novel regulator of connexin43 gap junctions.

Normalizing Flows for Hierarchical Bayesian Analysis: A Gravitational Wave Population Study (2022)

We propose parameterizing the population distribution of the gravitational wave population modeling framework (Hierarchical Bayesian Analysis) with a normalizing flow. We first demonstrate the merit of this method on illustrative experiments and then analyze four parameters of the latest LIGO/Virgo data release: primary mass, secondary mass, redshift, and effective spin. Our results show that despite the small and notoriously noisy dataset, the posterior predictive distributions (assuming a prior over the parameters of the flow) of the observed gravitational wave population recover structure that agrees with robust previous phenomenological modeling results while being less susceptible to biases introduced by less flexible models. Therefore, the method forms a promising flexible, reliable replacement for population inference distributions, even when data is highly noisy.

Glycotechnology for Decontamination of Biological Agents: A Model Study Using Ricin and Biotin-Tagged Synthetic Glycopolymers (2012)

Two types of biotin-tagged glycopolymers carrying lactose or glucose in clusters along the polyacrylamide backbone were prepared and subjected to decontamination analyses with the plant toxin ricin. A buffer solution containing the toxin was treated with one glycopolymer followed by streptavidin-magnetic particles. Supernatant solutions were analyzed with surface plasmon resonance and capillary electrophoresis, and revealed that the lactose glycopolymer "captured" this toxin more effectively than the glucose polymer. Free toxin was not detectable in the supernatant after treatment with the glycopolymer and magnetic particles; >99% decontamination was achieved for this potentially fatal biological toxin.
Optical properties of nanosized particles dispersed in colloidal solutions or arranged in 2D or 3D superlattices (1998)

In this paper it is demonstrated that colloidal assemblies used as templates are good candidates for controlling the size and shape of nanoparticles. The optical properties of metal nanoparticles dispersed in a colloidal solution differ with size and shape. When these particles are able to self-assemble, they form monolayers in a hexagonal network or crystal with a face-centered cubic arrangement. Such self-organizations induce changes in the optical properties. The size and composition of II–VI semiconductors are controlled independently. Quantum dots are observed. For semiconductor semimagnetic nanocrystals such as Cd1-yMnyS, the fluorescence due to isolated Mn2+ ions is attributed to the aging of the particles and not to a quantum dot effect, as predicted.

Clonal analysis of NRAS activating mutations in KIT-D816V systemic mastocytosis (2010)

Cooperating genetic events are likely to contribute to the phenotypic diversity of KIT-D816V systemic mastocytosis. In this study, 44 patients with KIT-D816V systemic mastocytosis were evaluated for coexisting NRAS, KRAS, HRAS or MRAS mutations. Activating NRAS mutations were identified in 2 of 8 patients with advanced disease. NRAS mutations were not found in patients with indolent systemic mastocytosis. To better understand the clonal evolution of mastocytosis, we evaluated the cell compartments impacted by the NRAS and KIT mutations. Clonal mast cells harbored both mutations. KIT-D816V was not detected in bone marrow CD34(+) progenitors, whereas the NRAS mutation was present. These findings suggest that NRAS mutations may have the potential to precede KIT-D816V in clonal development. Unlike other mature lineages, mast cell survival is dependent on KIT and the presence of these two activating mutations may have a greater impact on the expansion of this cell compartment and in resultant disease severity.

Semantic relatedness for evaluation of course equivalencies (2012)

Semantic relatedness, or its inverse, semantic distance, measures the degree of closeness between two pieces of text determined by their meaning. Related work typically measures semantics based on a sparse base such as WordNet or Cyc that requires intensive manual efforts to build and maintain. Other work is based on a corpus such as the Brown corpus, or more recently, Wikipedia. 
This dissertation proposes two approaches to applying semantic relatedness to the problem of suggesting transfer course equivalencies. Two course descriptions are given as input to feed the proposed algorithms, which output a value that can be used to help determine if the courses are equivalent. The first proposed approach uses traditional sources such as WordNet and corpora for courses from multiple fields of study. The second approach uses Wikipedia, the openly-editable encyclopedia, and it focuses on courses from a technical field such as Computer Science. 
This work shows that it is promising to adapt semantic relatedness to the education field for matching equivalencies between transfer courses. A semantic relatedness measure using traditional sources such as WordNet performs relatively well on non-technical courses. However, due to the knowledge acquisition bottleneck, such a resource is not ideal for technical courses, which use an extensive and growing set of technical terms. To address the problem, this work proposes a Wikipedia-based approach which is later shown to be more correlated to human judgment compared to previous work.
Inducing Social Self‐Sorting in Organic Cages To Tune The Shape of The Internal Cavity (2020)

Many interesting target guest molecules have low symmetry, yet most methods for synthesising hosts result in highly symmetrical capsules. Methods of generating lower symmetry pores are thus required to maximise the binding affinity in host-guest complexes. Herein, we use mixtures of tetraaldehyde building blocks with cyclohexanediamine to access low-symmetry imine cages. Whether a low-energy cage is isolated can be correctly predicted from the thermodynamic preference observed in computational models. The stability of the observed structures depends on the geometrical match of the aldehyde building blocks. One bent aldehyde stands out as unable to assemble into high-symmetry cages-and the same aldehyde generates low-symmetry socially self-sorted cages when combined with a linear aldehyde. We exploit this finding to synthesise a family of low-symmetry cages containing heteroatoms, illustrating that pores of varying geometries and surface chemistries may be reliably accessed through computational prediction and self-sorting.

Thrombin generation estimates the anticoagulation effect of direct oral anticoagulants with significant interindividual variability observed (2017)

: Direct oral anticoagulants (DOACs) are increasingly being used, primarily due to their drug stability and patient convenience. Although these drugs have been evaluated to be well tolerated in numerous clinical trials, their impact on in-vivo anticoagulation effect, variability and therapeutic drug level remains unknown. Hence, we aim to study the effect and variability of DOACs on thrombin generation via the calibrated automated thrombogram. Anonymized coagulation specimens from outpatients on warfarin were collected. Pooled normal plasma samples were spiked with increasing concentrations of dabigatran, rivaroxaban and apixaban. Similarly, plasma samples with normal coagulation profiles were spiked with two concentrations each of dabigatran, rivaroxaban and apixaban. Thrombin generation via calibrated automated thrombogram was run using the above samples and compared with a dataset of normal controls. Increasing international normalized ratio was associated with a reduction of endogenous thrombin potential (ETP) and thrombin peak and increasing lag time. Factor Xa inhibitors produced a flattened thrombin generation curve with a reduction of thrombin peak and relative preservation of ETP. Direct thrombin inhibitors produced a reduction of both ETP and thrombin peak and increasing lag time. Seventy-one citrated plasma samples (26 dabigatran, 21 rivaroxaban and 24 apixaban) were evaluated. The two concentrations produced a reduction of thrombin generation parameters with significant interindividual variability compared with neat plasma of 35-93, 13-31 and 18-71% and for dabigatran, rivaroxaban and apixaban, respectively. Thrombin generation can measure the anticoagulation effect of commonly used DOACs, with each drug having a unique thrombin generation profile. The variability noted using the same concentration suggests significant interindividual pharmacodynamic differences, which maybe relevant with respect to efficacy as well as bleeding side effects. Further delineation of the modifiers of interindividual differences is required in the in-vivo setting.

Micropropagation of the native species Anthurium antioquiense Engl. for conservation purposes Micropropagación de la especie nativa Anthurium antioquiense Engl. para su conservación (2014)

RESUMEN Anthurium antioquiense Engl. is a native plant belonging to the Araceae family. It grows on rocks in clear-water rivers and well-protected zones, similar to the waters in certain watersheds of the Antioquia Department, Colombia. Loss of habitat has threatened this promising ornamental plant species, which is also important because of its role in the ecosystem. In vitro tissue culture is considered an efficient alternative for the propaga tion of endangered species with the aim of establishing short-, medium- and long-term conservation programs. In the present research, in vitro introduction and shoot induction from A. antioquiense seedlings were performed. The highest production of shoots was obtained in a ½ MS (half-salt content) medium with 1 mg L -1 of BAP, which attained a 23.7 shoots/explant per month multiplication rate. The in vitro plants generated from shoots were individualized and transferred to a growth regulator-free medium. Rooting did not require the presence of growth regulators, and the adaptation of the in vitro plants to ex vitro conditions achieved a 98% survival rate. Anthurium antioquiense Engl. es una planta nativa perteneciente a la familia Araceae. Crece sobre rocas en rios de aguas claras y en zonas protegidas, caracteristicas de algunas cuencas hidrograficas del departamento de Antioquia-Colombia. La perdida de habitat amenaza esta promisoria especie ornamental, la cual tambien es importante debido a su incidencia en el ecosistema. El cultivo de tejidos in vitro se considera una alternativa eficiente para la propagacion de las especies en peligro de extincion, con el fin de establecer programas de conservacion a corto, mediano o largo plazo. En el presente trabajo de investigacion, se llevo a cabo la introduccion e induccion de brotes in vitro de A. antioquiense. La mayor produccion de brotes se obtuvo en medio ½ MS (contenido de sales a la mitad) con 1 mg L -1 de BAP (23,7 brotes/explante por mes). Las plantas in vitro obtenidas a partir de los brotes fueron individualizadas y transferidas a medio libre de reguladores de crecimiento. El enraizamiento se realizo sin presencia de reguladores de crecimiento, y la adaptacion de las plantas in vitro a condiciones ex vitro alcanzo una tasa de supervivencia del 98%.
Chiral Phosphoric Acid-Catalyzed Addition of Thiols to N-Acyl Imines: Access to Chiral N,S-Acetals (2011)

The first catalytic asymmetric method to prepare enantioenriched N,S-acetals using chiral BINOL phosphoric acids is reported. The reaction combines N-acyl imines with thiols to generate products in excellent yield and enantioselectivity. The addition reaction could also be achieved with an exceptional substrate to catalyst (S/C) molar ratio. Electron-rich and electron-deficient aromatic N-acyl imines, as well as a broad range of aliphatic and aromatic thiols, showed excellent reactivity.
Building a Control-flow Graph from Scheduled Assembly Code (2002)

A variety of applications have arisen where it is worthwhile to apply code optimizations directly to the machine code (or assembly code) produced by a compiler. These include link-time whole-program analysis and optimization, code compression, binaryto-binary translation, and bit-transition reduction (for power). Many, if not most, optimizations assume the presence of a control-flow graph (cfg). Compiled, scheduled code has properties that can make cfg construction more complex than it is inside a typical compiler. In this paper, we examine the problems of scheduled code on architectures that have multiple delay slots. In particular, if branch delay slots contain other branches, the classic algorithms for building a cfg produce incorrect results. We explain the problem using two simple examples. We then present an algorithm for building correct cfgs from scheduled assembly code that includes branches in branch-delay slots. The algorithm works by building an approximate cfg and then refining it to reflect the actions of delayed branches. If all branches have explicit targets, the complexity of the refining step is linear with respect to the number of branches in the code. Analysis of the kind presented in this paper is a necessary first step for any system that analyzes or translates compiled, assembly-level code. We have implemented this algorithm in our power-consumption experiments based on the TMS320C6200 architecture from Texas Instruments. The development of our algorithm was motivated by the output of TI’s compiler.
80–110 GHz MMIC amplifiers using a 0.1‐μm GaAs‐based mHEMT technology (2012)

Abstract A 80–110 GHz broadband MMIC low noise amplifiers (LNAs) have been developed for W‐band passive image sensors.A monolithic microwave integrated circuit (MMIC) LNAs consists of a four‐stage single‐ended type and a four‐stage balanced type. The chip set was fabricated using a 0.1‐μm gate‐length InGaAs/InAlAs/GaAs metamorphic high electron mobility transistor process based on a four‐inch substrate. The single‐ended type LNA (ver.1) achieved a gain of 20 dB over in a band between 85 and 105 GHz and a noise figure of lower than 5.3 dB in a frequency range of 86.5–100 GHz. The single‐ended type LNA (ver.2) exhibited a gain of 27 dB with a noise figure of 4.3 dB at 94 GHz. The external DC biasing conditions of V ds and V gs were 1 and −0.2 V, respectively, and the total current consumption of the LNA was 40 mA. The chip size was 2 × 1.2 mm 2 . The balanced‐type amplifier demonstrated a measured small signal gain of over 18 dB from 80 to 100 GHz. The external DC biasing conditions of V ds and V gs were 1 and −0.2 V, respectively, and the total current consumption was 82 mA. The chip size was 2.9 × 2.5 mm 2 . © 2012 Wiley Periodicals, Inc.
