Swelling and mechanical properties of glycol chitosan/poly(vinyl alcohol) IPN‐type superporous hydrogels (2006)

Glycol chitosan/poly(vinyl alcohol) interpenetrating polymer network type superporous hydrogels were prepared using a gas foaming/freeze-drying method. The effect of the molecular weight of the strengthener, poly(vinyl alcohol) (PVA), on the swelling and mechanical behavior of the superporous hydrogels was investigated. The introduction of a small amount of high molecular weight PVA significantly enhanced the mechanical strength but slightly reduced the swelling capacity. The freezing/thawing (F/T) drying process had a significant effect on the physical properties of the glycol chitosan/PVA superporous hydrogels, because hydrogen bonds were formed between the PVA molecules as a result of the number of F/T cycles. The swelling ratio decreased but the mechanical strength increased with increasing freezing time. However, this effect was not as strong as the number of F/T cycles. The differential scanning calorimetry was used to examine how the thermal behavior associated with the hydrogen bond-induced crystalline structure was affected by the F/T process.

Cloprostenol-induced luteolysis in the marmoset monkey ( <i>Callithrix jacchus</i> ) (1985)

A single intramuscular injection of 0.5 micrograms cloprostenol was not luteolytic on Day 6 or 7 of the ovarian cycle (N = 3), but was luteolytic in some animals (3/5) on Day 8 and 9 and luteolytic in all 23 animals treated between Days 10 and 17 of the ovarian cycle, and in 7 animals treated between Days 19 and 43 of pregnancy. Luteal function was monitored by measurement of progesterone in peripheral blood using a simple and rapid non-extraction assay. There was a dramatic fall in peripheral blood progesterone to less than 10 ng/ml within 24 h of cloprostenol injection; progesterone remained at this low level until the day after post-treatment ovulation. The interval from cloprostenol injection to ovulation in animals treated between Days 8 and 17 was 10.7 +/- 0.3 days. A similar interval was found in pregnant animals. Embryos recovered from the uterus after cloprostenol treatment were morphologically normal (23/24).
Generation of nondiffracting Bessel beam using digital micromirror device (2013)

We experimentally demonstrated Bessel-like beams utilizing digital micromirror device (DMD). DMD with images imitating the equivalent axicon can shape the collimated Gaussian beam into Bessel beam. We reconstructed the 3D spatial field of the generated beam through a stack of measured cross-sectional images. The output beams have the profile of Bessel function after intensity modulation, and the beams extend at least 50 mm while the lateral dimension of the spot remains nearly invariant. Furthermore, the self-healing property has also been investigated, and all the experimental results agree well with simulated results numerically calculated through beam propagation method. Our observations demonstrate that the DMD offers a simple and efficient method to generate Bessel beams with distinct nondiffracting and self-reconstruction behaviors. The generated Bessel beams will potentially expand the applications to the optical manipulation and high-resolution fluorescence imaging owing to the unique nondiffracting property.
THE TUCK PROCEDURE: A SIMPLIFIED VAGINAL REPAIR FOR TREATMENT OF FEMALE URINARY INCONTINENCE (1990)

A minor operative procedure involving the excision of bilateral small elliptical 1 x 0.5 cm pieces of vaginal mucosa is described as a proposed alternative to a Kelly Repair. Twelve month success rate was 47%. The modus operandi of the procedure is examined with reference to the Integral Theory of Female Urinary Incontinence, as are the possible reasons for the operative failure.
Path planning of collision avoidance for unmanned ground vehicles: A nonlinear model predictive control approach (2020)

In addition to the safety of collision avoidance, the safety of lateral stability is another critical issue for unmanned ground vehicles in the high-speed condition. This article presents an integrated path planning algorithm for unmanned ground vehicles to address the aforementioned two issues. Since visibility graph method is a very practical and effective path planning algorithm, it is used to plan the global collision avoidance path, which can generate the shortest path across the static obstacles from the start point to the final point. To improve the quality of the planned path and avoid uncertain moving obstacles, nonlinear model predictive control is used to optimize the path and conduct second path planning with the consideration of lateral stability. Considering that the moving trajectories of moving obstacles are uncertain, multivariate Gaussian distribution and polynomial fitting are utilized to predict the moving trajectories of moving obstacles. In the collision avoidance algorithm design, a series of constraints are taken into consideration, including the minimum turning radius, safe distance, control constraint, tracking error, etc. Four simulation conditions are carried out to verify the feasibility and accuracy of the comprehensive collision avoidance algorithm. Simulation results indicate that the algorithm can deal with both static and dynamic collision avoidance, and lateral stability.

Privacy Preserving Risk Assessment of Credit Securities (2009)

Assessing the risk associated to structured financial products such as collateralized debt obligations, involves processing information about diverse risk factors: some information comes from the different sources directly in aggregated form, therefore it is not possible to estimate the correlation among different risk components. In this paper we address the problem of assessing the credit risk associated to a borrower or to a security by privacy preserving methods. Specifically we suggest use Secure Multiparty Computation to merge the information from the different sources so as to compute more accurately the overall risk profile of securitized assets, without disclosing the information from each individual source.

Fusidic acid - Topical antimicrobial in the management of staphylococcus aureus (2013)

Fusidic acid (FA) is derived from the fungus Fusidiumcoccineum which was originally isolated from monkey faeces and available in the market since 1962. FA inhibits bacterial protein synthesis by interference with elongation factor G (EF-G), which promotes translocation on the ribosome after peptide bond formation, preventing further elongation by inhibiting the GTPase function of the EF-G. The steroid like structure of FA confers good skin penetration and does not possess the unwanted side effects of steroids.
Antioxaluric and anticalciuric activity of lupeol derivatives (1995)

Lupeol and a number of its derivatives were synthesised and evaluated for the possible antiurolithiatic activity in rats against hydroxyproline induced hyperoxaluria and calciuria. Some of the compounds possessed promising antihyperoxaluric and antihypercalciuric activity indicating antiurolithiatic activity.

Outcomes of patients who participate in randomised controlled trials compared to similar patients receiving similar interventions who do not participate (2007)

This review indicates that participation in RCTs is not associated with greater risks than receiving the same treatment outside RCTs. These results challenge the assertion that the results of RCTs are not applicable to usual practice.
YopT, a new <i>Yersinia</i> Yop effector protein, affects the cytoskeleton of host cells (1998)

Extracellular Yersinia disarm the immune system of their host by injecting effector Yop proteins into the cytosol of target cells. Five effectors have been described: YopE, YopH, YpkA/YopO, YopP and YopM. Delivery of these effectors by Yersinia adhering at the cell surface requires other Yops (translocators) including YopB. Effector and translocator Yops are secreted by the type III Ysc secretion apparatus, and some Yops also need a specific cytosolic chaperone, called Syc. In this paper, we describe a new Yop, which we have called YopT (35.5kDa). Its secretion required an intact Ysc apparatus and SycT (15.0kDa, pl4.4), a new chaperone resembling SycE. Infection of macrophages with a Yersinia, producing a hybrid YopT-adenylate cyclase, led to the accumulation of intracellular cAMP, indicating that YopT is delivered into the cytosol of eukaryotic cells. Infection of HeLa cells with a mutant strain devoid of the five known Yop effectors (deltaHOPEM strain) but producing YopT resulted in the alteration of the cell cytoskeleton and the disruption of the actin filament structure. This cytotoxic effect was caused by YopT and dependent on YopB. YopT is thus a new effector Yop and a new bacterial toxin affecting the cytoskeleton of eukaryotic cells.
Range Image Segmentation Using Principal Curvatures and Principal Directions (2006)

This paper proposes a novel range image segmentation method. Taking the peak area of the surface as the seed, we apply the region growing to exactly locate the edge according to the characteristics of the principal curvatures and its directions. We apply the edge detection technology to the region growth rules, so the boundary localization is precise. To obtain more stable edge information, a multi-scale fusion approach is proposed. The experiments results on footprint range images show that the segmented patches contain footprint biometric information well and set a reliable basis for the further recognition.
Nanoscale Damping Characteristics of Boron Nitride Nanotubes and Carbon Nanotubes Reinforced Polymer Composites (2013)

This study compares the damping behavior of boron nitride nanotubes (BNNTs) and carbon nanotubes (CNTs) as reinforcement in PLC, a biodegradable copolymer. The damping behavior of PLC composites reinforced with 2 wt % or 5 wt % nanotube filler is evaluated by nanodynamic mechanical analysis (NanoDMA). The addition of 2 wt % CNT leads to the greatest enhancement in damping (tan δ) behavior. This is attributed to pullout in CNTs because of lower interfacial shear strength with the polymer matrix and a more effective sword-in-sheath mechanism as opposed to BNNTs which have bamboo-like nodes. BNNTs however have a superior distribution in the PLC polymer matrix enabling higher contents of BNNT to further enhance the damping behavior. This is in contrast with CNTs which agglomerate at higher concentrations, thus preventing further improvement at higher concentrations. It is observed that for different compositions, tan δ values show no significant changes over varying dynamic loads or prolonged cycles. This shows the ability of nanotube mechanisms to function at varying strain rates and to survive long cycles.
p53 Mutations, c-myc and bcl-2 Rearrangements in Human Non-Hodgkin's Lymphoma Cell Lines (1995)

Fourteen Non-Hodgkin's lymphoma cell lines were generated and assessed for the presence of structural p53, c-myc and bcl-2 gene changes. Single or multiple changes were observed in 11 of the lines. Alterations of the p53 gene were most frequent and documented for 10 lines by immunoprecipitation using the antibodies PAb 240 and PAb 1801, sequencing studies and Southern blot analysis. A detailed study was performed in one of the cell lines (OCI-Ly 4) for which material of the original tumor sample was available. Two point mutations identified by sequencing cDNA derived from the cell line were also present in the original tumor specimen. In contrast, DNA prepared from fibroblasts of the same patient did not show the mutations. Six of the 14 lines demonstrated c-myc rearrangements, while bcl-2 changes were observed in 4. The presence of c-myc was associated with shorter survival of this group of patients with aggressive disease. None of the other changes present as single or composite alterations were correlated with clinical outcome measures.
Safety Profile of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors: A Disproportionality Analysis of FDA Adverse Event Reporting System (2020)

Adverse event reports submitted to the US Food and Drug Administration (FDA) were analyzed to map the safety profile of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs). We conducted a disproportionality analysis of the adverse events (AEs) of EGFR-TKIs (gefitinib, erlotinib, afatinib, osimertinib) by data mining using the FDA adverse event reporting system (AERS) database, and by calculating the reporting odds ratios (ROR) with 95% confidence intervals. The FDA AERS database contained 27,123 EGFR-TKI-associated AERs within the reporting period from January 1, 2004 to March 31, 2018. Thirty-three preferred terms (PTs) were selected for analysis, and significant RORs were most commonly observed in the skin, nail, gastrointestinal tract, hepatic, eyes, and lungs. Unexpected adverse drug reactions were found in the "intestinal obstruction" and "hypokalaemia" in gefitinib and erlotinib, "hyponatraemia" in gefitinib, erlotinib and afatinib, "alopecia"in erlotinib, "hair growth abnormal" in afatinib, but not in "nausea" and "vomiting" listed on drug labels. The results of this study are consistent with clinical observation, suggesting the usefulness of pharmacovigilance research should be corroborated with the real-world FAERS data.
Properties and Applications of Microperforated Panels (2011)

Microperforated panels (MPP) are acoustic absorbers that are reclaimable, noncombustible, and environmentally friendly. Sound is attenuated due to viscous friction in the submillimeter size pores. The panels are typically spaced from a hard surface and are most effective when the acoustic particle velocity is a maximum in the pores. In this article, the theory of MPP absorbers is briefly reviewed, and their application to noise control problems is shown. We demonstrate that the sound absorption can be tuned to targeted frequency bands by adjusting the depth of the backing cavity and enhanced by partitioning the backing cavity. In many cases, the performance is comparable to foam occupying the same volume in an enclosure. Traditional sound absorbing materials like glass fiber and foam deteriorate over time and are non-renewable. Small particles become dislodged, travel through ventilation ducts, and pollute the air inside buildings. Though facings are often added to glass fiber and foam to prevent deterioration and to guard against dirt and oil being trapped, the facings are combustible and diminish the performance of sound absorption at high frequency. One of the more attractive alternatives to fibers and foams are microperforated panel (MPP) absorbers. For ordinary perforates such as those used in mufflers and silencers, hole diameters are on the order of millimeters or even centimeters and have little acoustic resistance. MPP absorbers have pore diameters that are submillimeter in size. Due to the small pores, MPP absorbers provide acoustic resistance, which enhances sound attenuation. Compared to traditional sound-absorbing materials, MPP absorbers are unique, because they are reclaimable, cleanable, noncombustible, rugged, fiber free, and light weight. They have been used successfully in the German Parliament Building 1 and are commercially used in construction equipment, building interiors, and mufflers. For example, Figure 1 shows a MPP absorber used in a reception area. Note that the absorber can be painted and is aesthetically pleasing. Figure 2 shows an MPP absorber used in the engine compartment of a boat. MPP absorbers are normally manufactured from plastic or metal. In the past, holes were circular in shape and were cut using a laser. Accordingly, MPP absorbers were more expensive than traditional materials and were considered too costly for commercial use. However, lower-cost MPP absorbers are now available. Instead of circular holes, slits are manufactured into metal or plastic. Slitshaped perforations have a slightly smaller acoustic resistance but function similar to circular holes for all practical purposes. 2,3 Figure 3 compares photos of MPP absorbers with circular holes and slits.

Measures of confidence associated with combining classification results (1991)

The problem under consideration is that of combining classification results from several classifiers. This problem was motivated by the US Navy's involvement in developing a system for integrating classification results from multiple sensors. As in any decision process one needs to quantify the uncertainty associated with the decision. A procedure based upon ranked lists from classification outputs is considered. Particular attention is given to the problem of assigning measures of confidence to the combined classification results where the interpretation is easily explained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Possible Mechanism for Involvement of Cysteine in Aroma Production in Wine (2002)

Under conditions close to those of wine, that is, low pH, aqueous medium, and low temperatures, this work describes N-(2-sulfanylethyl)-2-oxopropanamide (1), a new intermediate in the formation of 2-acetylthiazole from methylglyoxal and cysteine. 1 was characterized by MS, derivatization MS, and (1)H and (13)C NMR and was synthesized from 2-sulfanylethanamine and ethyl pyruvate. A formation pathway for 2-acetylthiazole from methylglyoxal and cysteine is proposed, in which 1 is a new intermediate in Maillard-type reactions in systems under mild conditions.
Active concentric ring electrode for non-invasive detection of intestinal myoelectric signals (2010)

Although the surface electroenterogram (EEnG) is a weak signal contaminated by strong physiological interference, such as ECG and respiration, abdominal surface recordings of the EEnG could provide a non-invasive method of studying intestinal activity. The goal of this work was to develop a modular, active, low-cost and easy-to-use sensor to obtain a direct estimation of the Laplacian of the EEnG on the abdominal surface in order to enhance the quality of bipolar surface monitoring of intestinal activity. The sensor is made up of a set of 3 concentric dry Ag/AgCl ring electrodes and a battery-powered signal-conditioning circuit. Each section is etched on a different printed circuit board (PCB) and the sections are joined to each other by surface mount technology connectors. This means the sensing electrodes can be treated independently for purposes of maintenance and replacement and the signal conditioning circuit can be re-used. A total of ten recording sessions were carried out on humans. The results show that the surface recordings of the EEnG obtained by the active sensor present significantly less ECG and respiration interference than those obtained by bipolar recordings. In addition, bioelectrical sources whose frequency fitted with the slow wave component of the EEnG (SW) were identified by parametric spectral analysis in the surface signals picked up by the active sensors.
