Ionic Self‐Assembly: Facile Synthesis of Supramolecular Materials (2003)

Abstract The technique of ionic self‐assembly, i.e., the coupling of structurally different building blocks by electrostatic interactions, a powerful tool to create new material nanostructures and chemical objects, is reviewed. The excellent availability of the starting products (charged tectonic units) and the simplicity of synthesis, by neat addition and cooperative stoichiometric precipitation with high purity, allow the recombinatorial synthesis of a whole range of functional materials and hybrids with interesting and versatile functions. Diverse combinations between polyelectrolytes, surfactants, clusters, and extended rigid organic scaffolds are discussed in detail, and the underlying principles of nanostructure formation are illustrated.
Inheritance of Handwriting Features (2015)

Handwriting is one of the acquired characteristics of humans.It is a mixture of nature and nurture. Parents play an important part in teaching pre-writing skills to their children. Genetics also has a role in shaping the writing habits of the writer (such as handedness and handwriting positions). This paper examines the handwritings of parents and their biological off-springs to determine the inheritance of handwriting features from one generation to the next generation. In this scheme,resemblances in the handwriting features of parents- off springs were studied using computational features based on MATLAB 8.3 software.

New Algorithms for Efficient High-Dimensional Nonparametric Classification (2006)

This paper is about non-approximate acceleration of high-dimensional nonparametric operations such as k nearest neighbor classifiers. We attempt to exploit the fact that even if we want exact answers to nonparametric queries, we usually do not need to explicitly find the data points close to the query, but merely need to answer questions about the properties of that set of data points. This offers a small amount of computational leeway, and we investigate how much that leeway can be exploited. This is applicable to many algorithms in nonparametric statistics, memory-based learning and kernel-based learning. But for clarity, this paper c oncentrates on pure k-NN classification. We introduce new ball-tree algorithms that on real-world data sets give accelerations from 2-fold to 100-fold compared against highly optimized traditional ball-tree-based k-NN . These results include data sets with up to 10 6 dimensions and 10 5 records, and demonstrate non-trivial speed-ups
Safety and walking ability of KAFO users with the C-Brace® Orthotronic Mobility System, a new microprocessor stance and swing control orthosis (2016)

The microprocessor stance and swing control orthosis may facilitate an easier, more physiological, and safer execution of many activities of daily living compared to traditional leg orthosis technologies. Clinical relevance This study compared patient-reported outcomes of a microprocessor stance and swing control orthosis (C-Brace) to those with traditional knee ankle foot orthosis and stance control orthosis devices. The C-Brace offers new functions including controlled knee flexion during weight bearing and dynamic swing control, resulting in significant improvements in perceived orthotic mobility and safety.

Relationship between exercise time and musculoskeletal problems in children (2019)

<b>Objectives:</b> The purpose of this study was to evaluate the relationship between exercise time and musculoskeletal problems and to determine the appropriate amount of exercise for children in both lower- and higher-grade levels of elementary and junior high schools. <b>Materials and Methods:</b> Mark-sheet-type questionnaires were distributed to and collected from all elementary and junior high schools in two cities. We collected 22,494 questionnaires in total. The relationship between exercise time and musculoskeletal problems was analyzed. The χ<sup>2</sup> test and multivariate logistic regression analysis were used for statistical analyses. <b>Results:</b> The mean exercise time in school, in addition to physical education time, was 3.1 hours per week. In 56% of the children, the exercise time was less than 2 hours per week, and in 13% of the children, the exercise time was more than 10 hours per week. Although the rate of sports injury increased with an increase in exercise time, the duration of one-leg stand (a test of balance and muscle strength) also increased with an increase in exercise time. The cut-off values for sports injuries in boys/girls were 2.9/2.9 hours, 4.0/2.9 hours, and 7.5/4.2 hours in lower grade elementary school, higher grade elementary school, and junior high school, respectively. <b>Conclusions:</b> Although an appropriate amount of exercise improves one's physical health and ability, excessive exercise leads to musculoskeletal problems. Approximately 7 hours/week of exercise is recommended for junior high school students. In elementary school, the exercise time should be carefully decided as the musculoskeletal system of the students is still immature.
Interpretation-guided signal processing via protocol analysis (2005)

A signal processing system which integrates signal and symbol processing was designed and initial implementation experiments were performed. The system design was derived from the systematic observation (protocol collection) and analysis of human signal processing activity. The resulting system consists of (i) expert rules, which process symbolic representations of signal characteristics at various levels of abstraction, and (ii) signal processing operators, which are invoked by the rules to extract signal features. This design parallels the apparent operational mode of a human analyst. The signal processing operators include those used by the human expert (e.g. FFT) and others that perform perceptual feature extraction normally done by the expert while reviewing plots of numeric algorithmic outputs. In comparison to previous signal/symbol processing systems, which relied mostly on symbol processing, our system is based on the concept that a small amount of planned signal processing can save a lot of symbol processing.
Computer algebra symbolic and algebraic computation (1982)

Computer algebra is an alternative and complement to numerical mathematics. Its importance is steadily increasing. This volume is the first systematic and complete treatment of computer algebra. It presents the basic problems of computer algebra and the best algorithms now known for their solution with their mathematical foundations, and complete references to the original literature. The volume follows a top-down structure proceeding from very high-level problems which will be well-motivated for most readers to problems whose solution is needed for solving the problems at the higher level. The volume is written as a supplementary text for a traditional algebra course or for a general algorithms course. It also provides the basis for an independent computer algebra course.
Metformin: A review (2008)

Metformin is a well-established ingredient of diabetes management, both as a monotherapy in early stages of type 2 diabetes and as adjunct therapy to virtually every other antihyperglycemic medicine available today. Despite low potency and a long list of contraindications, metformin has remained successful and even expanded experimental use due to its well-established effects on glucose metabolism and, as more recently demonstrated, its benefits on other cardiovascular risk factors. Unlike insulin and secretagogues, metformin does not increase body weight and when used as monotherapy does not likely cause hypoglycemia. The most common adverse effects associated with metformin are mild, transient gastrointestinal symptoms, which are usually self-limiting. These side effects can be minimized by initiating metformin therapy at a low dose and gradually titrating upward, and by taking metformin with meals. Lactic acidosis caused by metformin is rare, and the risk of this complication may be diminished by the observance of prescribing precautions and contraindications that avoid accumulation of metformin or lactate in the body. The many clinical benefits and the lack of safety risks when used with other antihyperglycemic agents have made metformin a preferred combination drug with other oral agents.
Preparation and characterization of cellulose-based foams via microwave curing (2013)

In this work, a mixture of a sodium salt of carboxymethylcellulose (CMCNa) and polyethylene glycol diacrylate (PEGDA700) was used for the preparation of a microporous structure by using the combination of two different procedures. First, physical foaming was induced using Pluronic as a blowing agent, followed by a chemical stabilization. This second step was carried out by means of an azobis(2-methylpropionamidine)dihydrochloride as the thermoinitiator (TI). This reaction was activated by heating the sample homogeneously using a microwave generator. Finally, the influence of different CMCNa and PEGDA700 ratios on the final properties of the foams was investigated. The viscosity, water absorption capacity, elastic modulus and porous structure were evaluated for each sample. In addition, preliminary biological characterization was carried out with the aim to prove the biocompatibility of the resulting material. The foam, including 20% of PEGDA700 in the mixture, demonstrated higher viscosity and stability before thermo-polymerization. In addition, increased water absorption capacity, mechanical resistance and a more uniform microporous structure were obtained for this sample. In particular, foam with 3% of CMCNa shows a hierarchical structure with open pores of different sizes. This morphology increased the properties of the foams. The full set of samples demonstrated an excellent biocompatibility profile with a good cell proliferation rate of more than 7 days.
Active Composite Polymeric Membranes for the Separation of Nd(III) (2004)

Abstract Active composite polymeric membranes were prepared in order to improve the lifetime of supported liquid membranes (SLM) for the separation of Nd(III). The aim of the paper was to demonstrate the applicability of these type of composite membranes, based on two layer of polysulfone (PSf) and polyamide (PA), for metal transport. Thus, the membrane characterization, the influence of the carrier concentration in the transport, and the stability of the membranes have been studied. The results obtained are quite satisfactory, both from the standpoint of transport ability and stability. The need for an efficient carrier has been demonstrated and its influence reported. In addition, a preliminary investigation of the transport mechanism has been performed.

Emission Imaging Spectroscopic and Shadowgraphic Studies on the Growth Dynamics of Graphitic Carbon Particles Synthesized by CO2 Laser Vaporization (1999)

Emission imaging spectroscopy and shadowgraphy were applied to study the growth of carbon particles synthesized by 20-ms CO2 laser-pulse irradiation at 0.5−1.5 × 105 W/cm2 onto a graphite target in an Ar gas atmosphere (300−760 Torr). Emission images of growing carbon clusters and/or particles in a vaporization plume, measured with a temporal resolution of 1.67 ms, showed a constricted structure near the target that expanded widely into the Ar gas environment. On the other hand, the emission images of C2, not showing the constricted structure, indicated its presence close to the target and expansion in a narrow region. When directly ejected and/or formed carbon species (C, C2, and C3 , respectively) with velocities of 0.3−2.6 × 103 cm/s depart from the graphite surface, the formation of hot carbon clusters and/or particles begins and continues in the expanding plume. In shadowgraph images, the formation of a mushroom cloud containing darkened areas and black spots (size < 1 mm), probably corresponding to ∼80-nm-diameter graphitic carbon particles, was observed after 5 ms from the start of the laser irradiation. The number of particles increased rapidly from 5 to 25 ms. We propose a model of particle growth in a viscous carbon flow, where the temporal and spatial evolution of carbon species (the cluster formation and decrease in kinetic energies) and the condensation of clusters play essential roles with temperature reduction through the interaction with Ar atoms.
ENKEPHALIN RECEPTORS IN THE EMETIC CHEMORECEPTOR TRIGGER ZONE OF THE DOG (1981)

1 The emetic action of Met-enkephalin, morphine and naloxone was studied following their administration into the cerebral ventricles of dogs through chronically implanted cannulae and the effect on the responses of ablating the chemorceptor trigger zone (CTZ) was investigated. The opiate antagonist, naloxone, was used to determine the role of enkephalin receptors in emetic responses.2 Administration of Met-enkephalin (1.0 mug/kg) into the IVth ventricle regularly evoked emesis with an average latency of 35 s. A dose of morphine (2.5 mug/kg) which was five times larger was required for a consistent emetic response when introduced into the lateral cerebral ventricle (i.c.v.) as compared to the dose required by the IVth ventricular route. The latency of emetic responses by the latter route of injection of morphine was shorter. This is in accord with an action of morphine on the emetic CTZ.3 After bilateral ablation of the CTZ, intraventricular injections of Met-enkephalin and morphine failed to produce emesis even when given in doses that were 5 to 10 times the dose which regularly elicited emesis in animals with intact CTZ. The emesis produced in dogs by intraventricular Met-enkephalin and morphine is thus fully accounted for by an action on the CTZ.4 Naloxone (i.c.v.) in doses up to 10.0 mug/kg did not cause emesis. However, higher doses of naloxone elicited dose-dependent emesis in dogs. The 100% emetic dose of naloxone was found to be 160 mug/kg and the latency of emesis was 180 s. Unlike Met-enkephalin and morphine, naloxone continued to elicit emesis in CTZ-ablated animals.5 Pretreatment with intraventricular naloxone (1 to 8 mug/kg) blocked the emetic responses induced by intraventricular Met-enkephalin and morphine but not that to apomorphine. The selective protective action of the opiate antagonist against Met-enkephalin and morphine supports the presence of enkephalin receptors in the emetic CTZ.
Orofacial effects of antiretroviral therapies (2001)

This paper summarises some of the oral adverse effects of antiretroviral agents. Some are related to bone marrow suppression which may also predispose to mouth ulcers. Erythema multiforme and toxic epidermal necrolysis are especially well recognized in HIV disease, particularly as reactions to sulphonamides and to antiretroviral agents. Oral lichenoid reactions have been described in HIV disease often relating to zidovudine use. Didanosine has also produced erythema multiforme and not unusually induces xerostomia, again by an unknown mechanism. Xerostomia may be seen in up to one-third of patients taking didanosine. Taste abnormalities are common with the protease inhibitors and oral and perioral paraesthesia can be a disturbing adverse effect. Ritonavir in particular can give rise to circumoral paraesthesia in over 25% of patients. Indinavir can also produce cheilitis.
ΔNp63 Is Essential for Epidermal Commitment of Embryonic Stem Cells (2008)

In vivo studies have demonstrated that p63 plays complex and pivotal roles in pluristratified squamous epithelial development, but its precise function and the nature of the isoform involved remain controversial. Here, we investigate the role of p63 in epithelial differentiation, using an in vitro ES cell model that mimics the early embryonic steps of epidermal development. We show that the DeltaNp63 isoform is activated soon after treatment with BMP-4, a morphogen required to commit differentiating ES cells from a neuroectodermal to an ectodermal cell fate. DeltaNp63 gene expression remains high during epithelial development. P63 loss of function drastically prevents ectodermal cells to commit to the K5/K14-positive stratified epithelial pathway while gain of function experiments show that DeltaNp63 allows this commitment. Interestingly, other epithelial cell fates are not affected, allowing the production of K5/K18-positive epithelial cells. Therefore, our results demonstrate that DeltaNp63 may be dispensable for some epithelial differentiation, but is necessary for the commitment of ES cells into K5/K14-positive squamous stratified epithelial cells.
Antibacterial Activity of Silver Doped Titanate Nanowires on Ti Implants (2016)

A nanostructured film composed of one-dimensional titanate nanowires (TNWs) was employed as a carrier of Ag nanoparticles and chitosan (CS) to improve the surface antibacterial activity and biocompatibility of titanium implants. A TNWs film was produced on a Ti substrate by an alkali hydrothermal reaction and subsequently doped by Ag nanoparticles through an ultraviolet light chemical reduction. The CS nanofilm was deposited on the Ag nanoparticles through a spin-assisted layer by layer assembly method. The results disclosed that Ag nanoparticles were successfully carried by TNWs and homogeneously distributed on the entire surface. Moreover, a CS nanofilm was also successfully deposited on the Ag nanoparticles. Antibacterial tests showed that the samples modified with a higher initial concentration of AgNO3 solution exhibited better antibacterial activity, and that a CS nanofilm could further improve the antibacterial activity of the TNWs. Cell viability and ALP tests revealed that the release of Ag(+) was detrimental for the growth, proliferation, and differentiation of MC3T3, and that CS could lower the negative effects of Ag gradually as the incubation time increased.
Soot Combustion over Lanthanum Cobaltites and Related Oxides for Diesel Exhaust Treatment (2010)

This paper reports a comparative study of a series of La1−x(M)xCoO3 (M = Ce and Sr) perovskites and the related M′Ox (M′ = La, Co, Ce, and Sr) sample oxides. These catalysts were characterized by N2 adsorption, X-ray diffraction (XRD), temperature-programmed desorption (TPD) of oxygen, temperature-programmed reduction (TPR) by hydrogen, and temperature-programmed combustion (TPC) of soot. In the presence of perovskite-type catalysts, the soot oxidation was promoted, showing a shift of CO2 peaks toward lower temperature compared to the non-catalytic process. In addition, the catalytic activity of these perovskites was found to follow the trend La0.8Ce0.2CoO3 > La0.9Ce0.1CoO3 > La0.9Sr0.1CoO3 > La0.8Sr0.2CoO3 ≈ LaCoO3. A mechanism was proposed with an attack of soot by surface oxygen species, which migrate from the perovskite surface. The generation of CO (or carbonyl groups) as an intermediate and the possible formation of carbonate species over the most basic compounds are also discussed.
