Comparison of Cemented and Non-cemented Allografts in Dogs with Osteosarcoma (1998)

Summary This study compares the radiographic and histological appearance of cemented and non-cemented massive cortical allografts in dogs that underwent a limb sparing procedure for osteosarcoma of the distal radius. Treatment consisted of removal of the affected bone and pancarpal arthrodesis using non-cemented (n = 13) or cemented (n = 47) fresh-frozen allografts. Allografts were evaluated using a radiographic and histological scoring system and compared statistically between groups. Allografts with better healing received a higher radiographic score and a lower histological score. The mean radiographic scores, for proximal union and distal union, were significantly greater in the non-cemented group at most evaluation periods. Complications after the operation included screw, plate, allograft and host bone failure, infection and local tumour recurrence. Screw failure in the allograft and allograft failure were significantly more common in the non-cemented group. Histological examination was performed on 44 dogs and cement increased the mean combined histological scores, and mean healing scores of the distal host-graft interface significantly. The use of cemented allografts significantly decreases complications associated with implant loosening or allograft failure but may slightly delay allograft healing. At this point, the clinical relevance of the delay in healing is questionable and the benefits of intramedullary PMMA would appear to outweigh this relative delay in healing. This study evaluated 60 radial allografts after limb sparing procedures using a standardized radiological and histological scoring system. The use of cemented allografts significantly decreased complications associated with implant loosening or allograft failure but may slightly delay allograft healing.
Nurse staffing and unplanned extubation in the pediatric intensive care unit* (2005)

Pediatric patients are more likely to experience an unplanned extubation when being cared for by a nurse assigned to two patients compared with a nurse caring for one patient. To provide safe patient care, health care policymakers and hospital administrators should consider the nurse-to-patient ratio and its potential association with adverse events in hospitalized children.
Bioactive compounds in cereal grains – occurrence, structure, technological significance and nutritional benefits – a review (2012)

This review presents current information about principal, biologically active compounds contained in grains of cereals that are most popular in Europe (wheat, rye, barley and oat). The tendency to provide consumers with safe foods, which promote their health and are based on cereal grains and/or their components with the high nutritive value, has been recently observed. The intake of protective substances contained in whole grains and their fractions contributes to a decreased risk of food-dependent diseases like the coronary heart disease and insulin-dependent diabetes. This study describes the structure, occurrence in cereal grains, technological importance and beneficial influence on human health of bioactive substances such as arabinoxylans, β-glucans, alkylresorcinols, tocols and phytosterols.
Specific endotoxic lipopolysaccharide-binding proteins on murine splenocytes. II. Membrane localization and binding characteristics. (1988)

We have characterized the binding of LPS to an 80-kDa LPS-binding protein detected by an LPS photoaffinity probe to be present on murine splenocytes. Specific binding of LPS to the 80-kDa protein is directly proportional to LPS concentration at low concentrations of LPS and is saturable at high concentrations of LPS. Binding is inhibited by both homologous and heterologous underivatized LPS as well as by polysaccharide-free lipid A, indicating a specificity for the biologically active component of LPS. Analysis of the kinetics of binding indicate a time-dependent increase over the first 15 min, but increases are not detected after this time. Binding of LPS to the 80-kDa LPS-binding protein is reduced but still readily detectable at 4 degrees C in the presence of azide. The presence of the 80-kDa LPS-binding protein in an isolated cytoplasmic membrane fraction of murine splenocytes as well as its release from intact splenocytes by octylglucoside suggest that this LPS-binding protein is membrane localized. The results are consistent with, but do not establish unequivocally, the identity of the 80-kDa LPS-binding protein as a specific membrane receptor for lipid A.
ESR Solid State Dosimetry: Behaviour of Various Amino Acids and Blend Preparation Procedures (1999)

In several laboratories all around the world, electron spin resonance (ESR) dosimetry is a well-established reference dosimetric system in industrial applications of ionising radiation, and its use is also proposed in radiation therapy and accident dosimetry. In the present experimental investigation preparation procedures of alanine-polyethylene solid state dosemeters with optimised characteristics were defined, both modifying the commonly used blend composition and preparation, and choosing the best ESR spectra recording conditions; some other amino acids that could be alternatives to alanine in obtaining ESR dosemeters with better performances than alanine ones were also tested. Results obtained up to now (the research is still under way) confirm that alanine seems to be the most suitable material for ESR dosimetry. Methods to improve reproducibility are also discussed.
Study of a Double Bubbler for Material Balance in Liquids (Training Report 2013) (2013)

The objective of this project was to determine the potential of a double bubbler to measure density and fluid level of the molten salt contained in an electrorefiner. Such in-situ real-time measurements can provide key information for material balances in the pyroprocessing of the nuclear spent fuel. This theoretical study showed this technique has a lot of promise. Four different experiments were designed and performed. The first three experiments studied the influence of a variety of factors such as depth difference between the two tubes, gas flow rate, the radius of the tubes and determining the best operating conditions. The last experiment purpose was to determine the precision and accuracy of the apparatus during specific conditions. The elected operating conditions for the characterization of the system were a difference of depth of 25 cm and a flow rate of 55 ml/min in each tube. The measured densities were between 1,000 g/l and 1,400g/l and the level between 34cm and 40 cm. The depth difference between the tubes is critical, the larger, the better. The experiments showed that the flow rate should be the same in each tube. The concordances with theoretical predictions were very good. The density precision was very satisfying (spread<0.1%) and the accuracy was about 1%. For the level determination, the precision was also very satisfying (spread<0.1%), but the accuracy was about 3%. However, those two biases could be corrected with calibration curves. In addition to the aqueous systems studied in the present work, future work will focus on examining the behavior of the double bubbler instrumentation in molten salt systems. The two main challenges which were identified in this work are the effect of the temperature and the variation of the superficial tension.
Novel method of axis alignment in orbital angular momentum wireless communication (2015)

The key obstacle to exploiting orbital angular momentum in wireless communication is the influence of axis misalignment on detection side. This paper summarizes the effects of axis misalignment quantitatively and presents novel automatic methods to overcome the obstacle under the ideal (noiseless) condition. Numerical results in the far field demonstrate the effectiveness of our approach to make orbital angular momentum in wireless communication feasible and reliable.
A Second Look at the Least-Squares Algorithm for Recovering Information from Optical Flow (1987)

The changes in an image arising from the motion of the environment have been intensively studied over the past few years. These changes, termed optical flow, depend on both the motion and the shape of the environment. The central problem in the study of optical flow is to find the best way of recovering information about the motion and shape of the environment from the associated optical flow field. The author has previously shown (1986, 1987) that some parameters of the motion can be recovered with greater accuracy than the remaining parameters, provided the optical flow field arises from an irregular moving rigid surface. A surface is classed as irregular if the set of inverse distances to points on the surface do not possess a good linear approximation. The algorithm in question is based on a least-square error function, epsilon ( nu ). In the case of an optical flow field arising from an irregular moving rigid surface, there in a simple approximation to epsilon ( nu ) which can be used to predict the performance of the algorithm in situations of practical interest. Experimental results show that the approximation to epsilon ( nu ) is astonishingly accurate. In this paper the approximation to epsilon ( nu ) is given and some experiments to check this approximation are described.

Stack-based typed assembly language (2002)

This paper presents STAL, a variant of Typed Assembly Language with constructs and types to support a limited form of stack allocation. As with other statically-typed low-level languages, the type system of STAL ensures that a wide class of errors cannot occur at run time, and therefore the language can be adapted for use in certifying compilers where security is a concern. Like the Java Virtual Machine Language (JVML), STAL supports stack allocation of local variables and procedure activation records, but unlike the JVML, STAL does not pre-suppose fixed notions of procedures, exceptions, or calling conventions. Rather, compiler writers can choose encodings for these high-level constructs using the more primitive RISC-like mechanisms of STAL. Consequently, some important optimizations that are impossible to perform within the JVML, such as tail call elimination or callee-saves registers, can be easily expressed within STAL.
Effects of molecular structure on the permeability and permselectivity of aromatic polyimides (1996)

Permeability coefficients of H2, O2, and N2 were measured under 10 atm at the temperature from ambient temperature up to 150°C in a series of structurally different aromatic homo-and copolyimides, which were prepared from 4,4′-oxydianiline (ODA) or 4,4′-methylene dianiline (MDA) with various aromatic dianhydrides. The study shows that the molecular structure of the polyimides strongly influences gas permeability and permselectivity. As a result, the permeability coefficients of the polyimide membranes for each gas vary by over two orders of magnitude. In general, among the polyimide membranes studied, the increase in permeability of polymers is accompanied by the decrease in permselectivity, and the MDA-based polyimide membranes have higher permeability than ODA-based ones. Among the polyimides prepared from bridged dianhydrides, the permeability coefficients to H2, O2, and N2 are progressively increased in the order BPDA <BTDA <ODPA ∼ TDPA <DSDA <SiDA <6FDA, while H2/N2 and O2/N2 permselectivity coefficients are progressively decreased in the same order. The copolyimide membranes, which were prepared from 3,3′,4,4′-biphenyltetracarboxylic dianhydride (BPDA), bis(3,4-dicarboxyphenyl)dimethylsilane dianhydride (SiDA), and ODA, have favorable gas separation properties and are useful for H2/N2 separation applications. © 1996 John Wiley & Sons, Inc.
The in Situ Polymerization of Ethylene Ureas and Ethylene Amides Within the Fibers of Cotton (1961)

A research program has been carried out to investigate a new approach to cotton finishing. This approach has involved a study of various diaziridinyl compounds, such as those obtained by reacting ethylene imine with org-anic diisocyanates, diacid chlorides, and bischloroformates as potential cross-linking agents for cotton cellulose to produce "minimum care" or "wash-wear" fabric finishes. Over 25 different aziridinyl com pounds were prepared experimentally and screened for utility on the basis of water solubility and effect on such fabric properties as crease-recovery angle, tear strength, breaking strength and elongation, flex abrasion, washfastness, and chlorine retention. The experimental finishes were applied to an 80 X 80-count cotton print cloth, using . laboratory-size padding and drying equipment. The diaziridinyl compounds based on aliphatic diisocyanates and bischloroformates were found to demonstrate the greatest utility for the contemplated application, particu larly those compounds prepared from hexaniethylene-1,6-diisocyanate and mono- and diethylene glycol bischloroformate precursors. Increases in crease-recovery angle in the range of 30-60% were achieved with these finishes under conditions of application generally similar to those employed for commercial polymethylol type finishes. While these particular diaziridinyl finishes impart considerable crease resistance to cotton cloth, they were found to generally cause less impairment of other fabric prop erties than an experimentally applied commercial polymethylol cotton finish (CEU resin). The diaziridinyl finishes, being nitrogen-containing compounds, demonstrate a strong tendency to retain chlorine after chlorine bleaching. Further development of curing techniques for application of these finishes should be considered as a possible means of reducing chlorine retention.
Compliance to topical anti-glaucoma medications among patients at a tertiary hospital in North India (2017)

Over 50% of the patients surveyed were non-compliant, and 35% demonstrated improper administration technique. Glaucoma patients should be educated on the importance of compliance and aids that minimize forgetfulness, and delivery systems facilitating the delivery of medications to the eye could be considered to enhance patient adherence.
Bidirectional battery charger for electric vehicle (2014)

Increase in electric vehicle mobility has encouraged the growth of vehicle to grid technology. Vehicle to grid technology allows bidirectional power flow between the battery of electric vehicle and the power grid. This allows peak load shaving, load leveling, voltage regulation and improvements of power system stability. Implementation of the vehicle to grid technology requires dedicated electric vehicle battery charger, which allows bidirectional power flow between power grid and electric vehicle battery. In this paper, a new control strategy for bidirectional battery charger is proposed. The proposed control strategy can charge and discharge an electric vehicle battery in both slow and fast mode. The performance of the bidirectional controller is verified by simulation in PSCAD/EMTDC software under different operating modes, which include fast charging, fast discharging, slow charging and slow discharging. The results show that the proposed control strategy performs well in all four modes.

Lipid-based antifungal agents: a concise overview. (2002)

The development of lipid formulations of antifungal drugs has been a remarkable progress in the systemic antifungal arena. The lipid-based amphotericin B formulations; amphotericin B lipid complex (ABLC), amphotericin B colloidal dispersion (ABCD), and liposomal amphotericin B (L-AMB) have been in clinical use since the 1990s. They are significantly less nephrotoxic than the parent compound and can be safely used at higher doses. The primary cost of these formulations is significantly high and the extent of data related to their head-to-head comparison remains limited. The lipid formulation of nystatin, liposomal nystatin, is another lipid-based polyene under development. Available data concerning the in vitro activity, pharmacokinetic profile, in vivo efficacy, and safety of these formulations are summarized in this overview.

Astronomical Image Subtraction by Cross-Convolution (2007)

In recent years, there has been a proliferation of wide-field sky surveys to search for a variety of transient objects. Using relatively short focal lengths, the optics of these systems produce undersampled stellar images often marred by a variety of aberrations. As participants in such activities, we have developed a new algorithm for image subtraction that no longer requires high-quality reference images for comparison. The computational efficiency is comparable with similar procedures currently in use. The general technique is cross-convolution: two convolution kernels are generated to make a test image and a reference image separately transform to match as closely as possible. In analogy to the optimization technique for generating smoothing splines, the inclusion of an rms width penalty term constrains the diffusion of stellar images. In addition, by evaluating the convolution kernels on uniformly spaced subimages across the total area, these routines can accommodate point-spread functions that vary considerably across the focal plane.
Synthesis and biological evaluation of new 5-methyl-N-(3-oxo-1-thia-4-azaspiro[4.5]-dec-4-yl)-3-phenyl-1H-indole-2-carboxamide derivatives (2006)

A series of new 5-methyl-N-(3-oxo-1-thia-4-azaspiro[4.5]dec-4-yl)-3-phenyl-1H-indole-2carboxamide derivatives (2 and 3) was synthesized and characterized by IR, 1 H-NMR, HSQC, HMBC, 13 C-NMR (APT), APCI mass spectral data and elemental analysis. All synthesized compounds were evaluated for in vitro antituberculosis activity against M.tuberculosis H37Rv. Compound 3c was found to provide the highest (90%) inhibition of mycobacterial growth in the primary screen conducted at 6.25 g/mL.
Resistant Staphylococcus aureus infections in the United States: A new classification, a new resistance and the implications for surveillance, prevention, and control (2008)

Methicillin-resistant Staphylococcus aureus (MRSA) infections are often defined as healthcare-associated (HA) or community-associated (CA) based on three different classification schemes: healthcare risk factor, infection type, or susceptibility pattern. This dissertation analyzed the sensitivity, specificity, and utility of these classifications using MRSA case data from Michigan. MRSA infections were voluntarily reported to the Michigan Department of Community Health (MDCH) from October 2004 through December 2005. Data on patient demographics, risk factors, and infection information were recorded on the MDCH MRSA Report Form and submitted with laboratory susceptibility test results. A total of 2,151 non-duplicate MRSA infections were reported. Pulsed-field gel electrophoresis (PFGE) tests were conducted on 244 randomly selected isolates from reported cases. The first project classified MRSA infections as HA or CA using each of the three classification schemes, then examined results for inconsistency across methods. Comparison of HA and CA results using the common classification schemes revealed a large proportion of inconsistent results. The second project used PFGE test result as a gold standard to consider the three classification schemes and other important contributing variables aimed at producing an improved multivariable classification model. This new model using infection type, susceptibility pattern, age and hospitalized as variables better predicted PFGE classification of HA or CA than any other single classification method. The third project evaluated accuracy of the new classification model and used it to define the epidemiology of Michigan MRSA infections. This analysis revealed that MRSA is prevalent across Michigan and CA-MRSA, particularly among males, blacks, people within correctional facilities, and people presenting to emergency departments. A final project produced a comprehensive review of the first seven cases of emergent vancomycin-resistant Staphylococcus aureus (VRSA) in the US. All VRSA cases had a history of prior MRSA and enterococcal infection or colonization; all had several underlying conditions and most had received vancomycin prior to their VRSA infection. In conclusion, the improved method to categorize MRSA infections as HA or CA, and characterization of the VRSA cases, provides new knowledge that will help to accurately target control efforts and prevention methods and messages to better combat this adept and evolving bacterium.
