Factors Affecting Noncompliance With Buprenorphine Maintenance Treatment (2014)

Patients found to be noncompliant were more likely to suffer from comorbid psychiatric illness. Patients who tested positive for benzodiazepines or cannabis were more likely to be noncompliant with treatment. Although the rate of noncompliance (inaccurate pill count) was high, patients were still found to be taking their prescribed buprenorphine as evidenced by positive UDS for buprenorphine/norbuprenorphine. In addition, our sample had a high rate of negative UDS screens for opioids and cocaine.
Phosphinic Tripeptides as Dual Angiotensin-Converting Enzyme C-Domain and Endothelin-Converting Enzyme-1 Inhibitors (2009)

A new series of phosphinic inhibitors able to interact with both angiotensin-converting enzyme (ACE) C-domain and endothelin-converting enzyme-1 (ECE-1), while sparing neprilysin (NEP), has been developed. The most potent and selective inhibitor in this series (compound 8(F2)) displays K(i) values of 0.65 nM, 150 nM, 14 nM and 6.7 microM toward somatic ACE C-domain, ACE N-domain, ECE-1, and NEP, respectively. Remarkably, in this series, the inhibitor's ability to discriminate between ECE-1 and NEP was observed to depend on the stereochemistry of the residue present in the inhibitor's P(1)' position. After iv administration, compound 8(F2) (10 mg/kg) lowered mean arterial blood pressure by 24 +/- 2 mmHg in spontaneously hypertensive rats, as compared with controls. Mixed ACE/ECE-1 inhibitor may lead to a new generation of vasopeptide inhibitors that should reduce the levels of angiotensin-II and endothelin-1, without interfering with bradykinin cleavage.

Adopting the political economy theoretical framework, the paper identifies analyses and proffer possible solutions to these social issues. Key words : Development, Modernization, Dependency, Corruption, Political Economy and Leadership.
Systematic identification of arsenic-binding proteins reveals that hexokinase-2 is inhibited by arsenic (2015)

Arsenic is highly effective for treating acute promyelocytic leukemia (APL) and has shown significant promise against many other tumors. However, although its mechanistic effects in APL are established, its broader anticancer mode of action is not understood. In this study, using a human proteome microarray, we identified 360 proteins that specifically bind arsenic. Among the most highly enriched proteins in this set are those in the glycolysis pathway, including the rate-limiting enzyme in glycolysis, hexokinase-1. Detailed biochemical and metabolomics analyses of the highly homologous hexokinase-2 (HK2), which is overexpressed in many cancers, revealed significant inhibition by arsenic. Furthermore, overexpression of HK2 rescued cells from arsenic-induced apoptosis. Our results thus strongly implicate glycolysis, and HK2 in particular, as a key target of arsenic. Moreover, the arsenic-binding proteins identified in this work are expected to serve as a valuable resource for the development of synergistic antitumor therapeutic strategies.
Treatment of the Painful Neuroma by Neuroma Resection and Muscle Implantation (1986)

The successful treatment of the painful neuroma remains an elusive surgical goal. This report evaluates one approach to the management of this problem which entails neuroma excision and placement of the proximal end of the nerve away from denervated skin, away from tension, and into a well-vascularized environment: muscle. Seventy-eight neuromas in 60 patients with a mean follow-up of 31 months (range 18 to 43 months) were evaluated. Sixty-seven percent of these patients involved Workmen's Compensation and 57 percent had had at least one previous operation to treat their pain. The results demonstrated good to excellent results in 82 percent of the treated nerves in the entire group. Factors that were predictive of a poorer outcome were (1) digital neuroma (p less than 0.0005), (2) Workmen's Compensation (p less than 0.01), and (3) three or more previous operations for pain (p less than 0.01). Transposition of nerves into small superficial muscles or muscles with significant excursion resulted in treatment failures. The etiology and histopathology of treatment failures are reviewed. Treatment of radial sensory neuromas by transposition of the radial sensory nerve into the brachioradialis muscle when any associated injury to the lateral antebrachial cutaneous nerve was also treated, gave good to excellent relief of pain, and improved hand function in 88 percent of the patients.
Modeling boron profiles in silicon after pulsed excimer laser annealing (2012)

In this work, we investigated four possible mechanisms which were candidates to explain the shape of boron profiles after ion implantation and melting excimer laser annealing in silicon. A laser with a wavelength of 308 nm and a pulse duration of ∼180 ns was used. To simulate this process, an existing model for the temperature and phase evolution was complemented with equations for the migration of dopants. Outdiffusion, thermodiffusion, segregation, and adsorption were investigated as possible mechanisms. As a result, we found that outdiffusion and segregation can be excluded as major mechanisms. Thermodiffusion as well as adsorption could both reproduce the build-up at low melt depths, but only adsorption the one at deeper melt depths. In both cases, ion beam mixing during SIMS measurement had to be taken into account to reproduce the measured profiles.
Myeloid-Derived Suppressor Cells Regulate Immune Response in Patients with Chronic Hepatitis B Virus Infection through PD-1–Induced IL-10 (2014)

Although myeloid-derived suppressor cells (MDSCs) are well known for their immunosuppressive function in several pathological conditions, the role of MDSCs in hepatitis B virus infection remains obscure. In this study, we investigated the frequency and function of MDSCs in the peripheral blood and liver of 91 chronic hepatitis B (CHB) patients. A higher percentage of MDSCs, defined as CD14(+)HLA-DR(-/low), was detected in peripheral blood of CHB patients than that of the healthy controls. Moreover, high expression of programmed death 1 (PD-1) and secretion of IL-10 in this population were determined. The frequency of MDSCs was positively correlated with serum viral load, but it was negatively correlated with liver inflammatory injury. These cells were also abundant in liver tissue of CHB patients and were related to necroinflammatory activity. Furthermore, we found that these cells could suppress hepatitis B virus-specific CD8(+) T cell response, including reduced proliferation and IFN-γ production, and inhibit degranulation of CD8(+) T cells, including reduced production of granzyme B and perforin. Importantly, PD-1-induced IL-10 production by MDSCs was responsible for the suppressive activity. To our knowledge, for the first time our study proved that CD14(+)HLA-DR(-/low)PD-1(+) MDSCs in CHB patients contribute to an inadequate immune response against the virus and lead to chronic infection, which represents a potential target for therapeutic intervention.
Morphine, the Proteus of organic molecules (2002)

This feature article encapsulates the senior author's longstanding interests in opiate chemistry and attempts to place it within an historical context and against the backdrop of related work by others who have viewed morphine as one of the pinnacles of natural product synthesis. Biomimetic and 'bioanalogous' routes to the morphine skeleton are discussed followed by approaches based on the elaboration of phenanthrene platforms. The latter include an asymmetric synthesis of ent-morphine developed in our laboratory.
Beam interactions, contrast and resolution in the SEM (1984)

SUMMARY Backscattered and secondary electrons are both used in the SEM for imaging purposes. The backscattered signal is the result of high angle elastic scattering events, while the secondary signal is the result of knock‐on inelastic collisions. The characteristic differences between images in the two modes arise from the details of the relevant interactions in the two cases. In order to examine this in a quantitative manner Monte Carlo electron trajectory simulation techniques have been used. Calculations of the ultimate resolution and depth of information of the secondary and backscattered images are presented, together with simulations of the edge brightness effect in high resolution secondary images and an analysis of the microanalytical application of atom number contrast in the backscattered mode.
Analytical expression for the standing wave intensity in photoresist (1986)

When a thin dielectric film placed between two semi-infinite media is irradiated with monochromatic plane waves, a standing wave is produced in the film. An analytical expression for the standing wave intensity within the film is derived. This expression is then expanded to include the effects of other dielectric films on either side of the film or an inhomogeneous film. Applications of these expressions are given for photolithographic modeling.
Immersion Cooling of Electronics in Fluidized Beds of Dielectric Particles (1989)

Abstract We are investigating fluidized beds of particles as a heat transfer medium for cooling electronic equipment. These fluidized beds share several of the attractive qualities of dielectric liquids but employ air rather than liquids in their operation. Experiments in cooling electronic circuit boards by directly immersing them in fluidized beds of dielectric particles have been performed. Heat dissipation from a simulated 20-pin flat pack in this fluidized environment was a factor of eight greater than forced convection without particles. In designs where heat conduction from the component to the circuit board is severely limited, enhancements approaching a factor of 50 are expected.
Relating Structure to Mechanism in Creatine Kinase (2005)

Found in all vertebrates, creatine kinase catalyzes the reversible reaction of creatine and ATP forming phosphocreatine and ADP. Phosphocreatine may be viewed as a reservoir of "high-energy phosphate" which is able to supply ATP, the primary energy source in bioenergetics, on demand. Consequently, creatine kinase plays a significant role in energy homeostasis of cells with intermittently high energy requirements. The enzyme is of clinical importance and its levels are routinely used as an indicator of myocardial and skeletal muscle disorders and for the diagnosis of acute myocardial infarction. First identified in 1928, the enzyme has undergone intensive investigation for over 75 years. There are four major isozymes, two cytosolic and two mitochondrial, which form dimers and octamers, respectively. Depending on the pH, the enzyme operates by a random or an ordered bimolecular mechanism, with the equilibrium lying towards phosphocreatine production. Evidence suggests that conversion of creatine to phosphocreatine occurs via the in-line transfer of a phosphoryl group from ATP. A recent X-ray structure of creatine kinase bound to a transition state analog complex confirmed many of the predictions based on kinetic, spectroscopic, and mutagenesis studies. This review summarizes and correlates the more significant mechanistic and structural studies on creatine kinase.
Celiac sprue: correlation with murine T cell responses to wheat gliadin components. (1982)

Celiac sprue is a disease in humans that is characterized by small intestinal mucosal injury and malabsorption. Dietary exposure to gliadin and similar proteins in rye and barley activates the disease in susceptible individuals. Celiac sprue appears to be the only disease with a marked HLA-association in which the proteins that activate the disease currently are well known. However, bread wheat gliadins are a complex mixture of proteins that contain at least 40 different components. In the present study we have purified the major gliadin components of Scout 66 wheat and used these proteins to examine murine T cell proliferative responses to gliadin. Differences in T cell proliferation stimulated by alpha-, beta-, gamma-, and omega-gliadins paralleled the known structural differences among these proteins. After priming with whole gliadin, the components that stimulated T cell proliferation were the same as those recognized to activate celiac sprue in humans. Studies with reduced and alkylated A-gliadin (i.e., S-methyl A-gliadin) suggested that epitopes determined by the native conformation of A-gliadin may be important in its interaction with T cells. By using three different A-gliadin peptides that span the entire molecule, T cell proliferative responses were shown to be stimulated predominantly by antigenic determinants on the NH2-terminal peptide.
Platinum Metal Complexes of Substituted Aryl Phosphines (1980)

Highlights of the co-ordination chemistry of platinum metal complexes of phosphorus-oxygen chelating agents are described. The ligands of interest all contain the oxygen bearing substituent (methoxy, hydroxy, formyl, carboxy-) ortho to a phosphine on a benzene ring; complexes of these ligands are efficient homogeneous catalysts for hydrogenation, isomerisation and polymerisation reactions. Furthermore, these studies have revealed structural and reactivity patterns which are suggestive of new and improved strategies towards useful catalytic systems.
Depletion of eosinophils by anti-IL-5 monoclonal antibody treatment of mice infected with Trichinella spiralis does not alter parasite burden or immunologic resistance to reinfection (1992)

Mechanisms of parasite killing by eosinophils are widely studied and are often implicated in mediating resistance to parasitic infection, especially in conjunction with specific antibodies. Evidence for the eosinophil as an anti-parasite killer cell in vivo is limited and may not justify the belief that eosinophils engage and/or kill infective helminths. We reexamined this question in a mouse model of trichinosis in which antisera to eosinophils were previously used to show the requirement for eosinophils in resistance to this nematode. The current studies used mAb to IL-5 to suppress eosinophil levels in CF1 mice infected with Trichinella spiralis. In mice given a primary infection and injected with an isotype control mAb or left untreated, the medullary and peripheral blood eosinophil numbers peaked at 3 wk postinfection (PI) and returned to baseline levels by 4 wk PI. Peripheral blood eosinophil numbers in infected mice injected with anti-IL-5 were maintained at levels below those of uninfected normal mice through 4 wk of infection. Histologically, there was a prominent eosinophil accumulation in infected, untreated, or control-mAb-treated mice associated with nurse cell complexes containing infective juveniles in skeletal muscle at 3 and 4 wk PI. This was largely eliminated in mice treated with anti-IL-5 mAb. However, the number of muscle stage juvenile worms recovered 3 and 4 wk PI after acid pepsin digestion was unaffected by eosinophil depletion. Challenge infections, in which mice were infected at day 0 with 125 muscle stage worms and challenged at day 28 PI with 350 muscle stage worms, developed peak eosinophil numbers in bone marrow and peripheral blood 3 wk after primary infection and 2 wk after challenge infection in mice receiving either no treatment or control mAb. In challenged mice receiving anti-IL-5 mAb, medullary and peripheral blood eosinophil numbers remained at or below those of uninfected animals. Although all groups exhibited significant resistance measured as muscle stage worm burdens 56 days PI, eosinophil depletion did not affect resistance of muscle worm recovery. These results suggest that eosinophils are not essential in the control of T. spiralis in either primary or challenge infections of CF1 mice. This in vivo study illustrates the questionable value of in vitro killing assays to assign effector function to any single inflammatory cell type.
Apoptosis pathways and their therapeutic exploitation in pancreatic cancer (2009)

Resistance to apoptosis (programmed cell death) is a characteristic feature of human malignancies including pancreatic cancer, which is one of the leading causes of cancer deaths in the western world. Defects in this intrinsic cell death program can contribute to the multistep process of tumorigenesis, because too little cell death can disturb tissue homeostasis. Further, blockade of apoptosis pathways can cause treatment failure, because intact apoptosis signalling cascades largely mediate therapy-induced cytotoxicity. The elucidation of apoptosis pathways in pancreatic carcinoma over the last decade has resulted in the identification of various molecular defects. How apoptosis pathways can be exploited for the treatment of pancreatic cancer will be discussed in this review.
A Computer Aided Geometric Design approach to contour map editing (1989)

A contour map is a convenient representation of three-dimensional data. Although, when displayed, it does not provide an immediate visual three-dimensional image, it is useful in practical applications. It is tedious to manually draw or extract data from a contour map. The ability to store contour maps for computer processing is thus desirable. A contour map is conventionally stored in a computer as a set of polygons. This method unfortunately requires a large amount of storage and is not convenient for subsequent editing of contour maps. More recent techniques use cubic splines with mathematical continuity. Although such techniques require less storage than the conventional method, they do not provide a convenient means for subsequent editing. From recent reports on research in Computer Aided Geometric Design as well as in Computer Aided Design and Computer Aided Manufacturing, it seems that cubic splines with geometric continuity rather than mathematical continuity are more appropriate for computer graphics applications. This article examines the appropriateness of geometric continuity in the development of software for contour map editing.

Zur Diagnostik und Therapie des thrombotischen Verschlusses der infrarenalen Bauchaorta (1993)

Der thrombotische Verschluß der infrarenalen Bauchaorta wird im medizinischen Sprachgebrauch allgemein als LERICHE-SYNDROM bezeichnet (26). Erstbeschreiber dieser Erkrankung war jedoch nicht der von 1879–1955 lebende französische Chirurg René Leriche, sondern Graham bereits im Jahre 1814.
Web-based collaborative tools for geospatial data exploration (2004)

Federal government agencies have collected large and highly complex federal statistical summaries and geo-reference data. Methods and tools for identifying patterns and uncovering multivariate relationships in the complex datasets have drawn attention in multiple fields. The approach we present here extends from and integrates perspectives from multiple fields, including exploratory data analysis (EDA), geovisualization, information visualization, and data mining. Important components of our research are supported by a NSF Digital Government grant (#99883451). Other support comes from a National Cancer Institute (NCI) contract. Our DG research is now being extended to develop comprehensive multivariate analysis methods and tools, through a grant from NCI (CA95949).
Coronary endothelial P-selectin in pathogenesis of myocardial ischemia-reperfusion injury (1998)

We investigated in vivo coronary P-selectin expression and its pathophysiological consequences in a murine model of myocardial ischemia-reperfusion (MI/R) using wild-type and P-selectin deficient (-/-) mice. Coronary P-selectin expression [microgram monoclonal antibody (MAb)/g tissue] was measured using a radiolabeled MAb method after 30 min of myocardial ischemia and 20 min of reperfusion. P-selectin expression in wild-type mice was significantly (P < 0. 01) elevated in the ischemic zone (0.070 +/- 0.010) compared with the nonischemic zone (0.037 +/- 0.008). Myocardial P-selectin expression was nearly undetectable in P-selectin -/- mice after MI/R. Furthermore, myocardial infarct size (% of area at risk) after 30 min of myocardial ischemia and 120 min of reperfusion was 42.5 +/- 4. 4 in wild-type mice and 24.4 +/- 4.0 in P-selectin -/- mice (P < 0. 05). In additional experiments of prolonged myocardial ischemia (60 min) and reperfusion (120 min), myocardial infarct size was similar in P-selectin -/- mice and wild-type mice. Our results clearly demonstrate the involvement of coronary P-selectin in the development of myocardial infarction after MI/R.
Adeno-associated Viral (AAV) Serotype 5 Vector Mediated Gene Delivery of Endothelin-converting Enzyme Reduces Aβ Deposits in APP + PS1 Transgenic Mice (2008)

Reduction of Abeta deposition is a major therapeutic strategy in Alzheimer's disease (AD). The concentration of Abeta in the brain is modulated not only by Abeta production but also by its degradation. One of the proteases involved in the degradation of Abeta peptides is endothelin-converting enzyme (ECE). In this study, we investigated the effects of an intracranial administration of a seroptype 5 recombinant adeno-associated viral vector (rAAV) containing the ECE-1 synthetic gene on amyloid deposition in amyloid precursor protein (APP) plus presenilin-1 (PS1) transgenic mice. The rAAV vector was injected unilaterally into the right anterior cortex and hippocampus of 6-month-old mice, while control mice received an AAV vector expressing green fluorescent protein (GFP). Immunohistochemical testing for the hemagglutinin (HA) tag appended to ECE revealed strong expression in areas surrounding the injection sites but minimal expression in the contralateral regions. Immunohistochemical tests showed that Abeta decreases in the anterior cortex and hippocampus in mice receiving the ECE synthetic gene. Further, decreases in Congo red positive deposits were also observed in both regions. These results indicate that increasing the expression of beta-amyloid degrading enzymes through gene therapy is a promising approach to the treatment of AD.
