Non-peptide δ opioid agonists and antagonists (1997)

Following a flurry of medicinal chemistry activity in the late 1980s, a number of non-peptide pharmacological tools, selective for the δ opioid receptors, became available to challenge the pre-eminent position occupied by the existing peptide δ ligands. The first non-peptide δ antagonist NTI (1) represented a breakthrough in this field. Several analogues have been subsequently synthesised and are currently being used to clarify the pharmacology associated with the δ opioid receptors. The discovery of the selective δ agonists TAN-67 (50), BW373U86 (56) and SNC 80 (62) represented another step towards the understanding of the involvement of the δ opioid receptor in a number of possible pathophysiological conditions. This review addresses the recent highlights and developments that have been made by several research groups in the design of potent and selective non-peptide δ ligands. Focus has been given to the different pharmacological actions of δ agonists and antagonists. Analgesia can be considered the historical target for drugs acting through the opioidergic system. However, contrary to existing μ opioid narcotic drugs, there is substantial evidence to suggest that selective δ opioid agonists may be safe and effective analgesics. Beside this very important therapeutic target, recent studies have revealed that such drugs may elicit a variety of other beneficial pharmacological effects. They may also positively modulate some activities of μ agonists such as morphine. Animal models have demonstrated that δ antagonists may also play an important pharmacological role per se having possible clinical applications in preventing drug abuse, in organ transplantation and as antitussive agents.
Alignment by maximisation of mutual information (1993)

A new information-theoretic approach is presented for finding the pose of an object in an image. The technique does not require information about the surface properties of the object, besides its shape, and is robust with respect to variations of illumination. In our derivation, few assumptions are made about the nature of the imaging process. As a result the algorithms are quite general and can foreseeably be used in a wide variety of imaging situations. Experiments are presented that demonstrate the approach registering magnetic resonance (MR) images with computed tomography (CT) images, aligning a complex 3D object model to real scenes including clutter and occlusion, tracking a human head in a video sequence and aligning a view-based 2D object model to real images. The method is based on a formulation of the mutual information between the model and the image called EMMA. As applied here the technique is intensity-based, rather than feature-based. It works well in domains where edge or gradient-magnitude based methods have difficulty, yet it is more robust than traditional correlation. Additionally, it has an efficient implementation that is based on stochastic approximation. Finally, we will describe a number of additional real-world applications that can be solved efficiently and reliably using EMMA. EMMA can be used in machine learning to find maximally informative projections of high-dimensional data. EMMA can also be used to detect and correct corruption in magnetic resonance images (MRI).
Synthesis of O‐Acyl‐L‐Homoserine by lipase (1989)

Abstract Lipases (EC 3.1.1.3) from Candida cylindracea and Rhizopus delemar were found to catalyze O‐acylation of L‐homoserine or L‐serine with free fatty acids or with fatty acids from triacylglycerol. The active pH range of the reation for O‐acylation was from 7.0 to 8.5. Emulsifying activity of O‐oleoyl‐L‐homoserine was higher than those of conventional surfactants.
Green Tea Consumption and Prostate Cancer Risk in Japanese Men: A Prospective Study (2007)

The incidence of prostate cancer is much lower in Asian than Western populations. Given that environmental factors such as dietary habits may play a major role in the causation of prostate cancer and the high consumption of green tea in Asian populations, this low incidence may be partly due to the effects of green tea. The JPHC Study (Japan Public Health Center-based Prospective Study) was established in 1990 for cohort I and in 1993 for cohort II. The subjects were 49,920 men aged 40-69 years who completed a questionnaire that included their green tea consumption habit at baseline and were followed until the end of 2004. During this time, 404 men were newly diagnosed with prostate cancer, of whom 114 had advanced cases, 271 were localized, and 19 were of an undetermined stage. Green tea was not associated with localized prostate cancer. However, consumption was associated with a dose-dependent decrease in the risk of advanced prostate cancer. The multivariate relative risk was 0.52 (95% confidence interval: 0.28, 0.96) for men drinking 5 or more cups/day compared with less than 1 cup/day (p(trend) = 0.01). Green tea may be associated with a decreased risk of advanced prostate cancer.
Analysis of chemical composition and its analgesic and anti-inflammatory activity of essential oil of sintoc bark (Cinnamomum sintoc bl.) using in vivo methods (2015)

Sintoc bark (Cinnamomum sintoc Bl) belongs to Lauraceae (the laurel family). It has been used empirically for a treatment for swelling caused by insects' bites. In this study, the research examined the analgesic activity and anti-inflammation of essential oil of sintocbark using in vivo methods. The mechanism of anti-inflammation was predicted using molecular docking against COX-2. Essential oil of sintoc bark was collected by distilling through steam distillation, and then analyzed by GC-MS. Analgesic and anti-inflammatory activity was examined by in vivo, which were conducted by writhing and carrageenan-induced methods, respectively. The findings showed that the tested sintoc bark oils contained 36 components of essential oil with eugenol (38.38 %) as a major compound. In the in vivo experiments, sintoc bark oils with doses 0.005 mL, 0.010 mL, and 0.020 mL/20g body weight significantly (p<0.05) reduced the number of writhing of mice when compared to negative control group. All of doses of sintoc bark oils gave significantly affect (confidence level 99 %) compare to negative control. Sintoc oil with dose 0.2 ml/200g had the strongest inhibition compare to positive control (indometasin 10 mg/kg body weight). The molecular docking results indicated that the compounds of aryl propanoid were generally potential to inhibit COX-2.
Haptic techniques for media control (2001)

We introduce a set of techniques for haptically manipulating digital media such as video, audio, voicemail and computer graphics, utilizing virtual mediating dynamic models based on intuitive physical metaphors. For example, a video sequence can be modeled by linking its motion to a heavy spinning virtual wheel: the user browses by grasping a physical force-feedback knob and engaging the virtual wheel through a simulated clutch to spin or brake it, while feeling the passage of individual frames. These systems were implemented on a collection of single axis actuated displays (knobs and sliders), equipped with orthogonal force sensing to enhance their expressive potential. We demonstrate how continuous interaction through a haptically actuated device rather than discrete button and key presses can produce simple yet powerful tools that leverage physical intuition.
A Parallel Graph Coloring Heuristic (1993)

The problem of computing good graph colorings arises in many diverse applications, such as in the estimation of sparse Jacobians and in the development of efficient, parallel iterative methods for solving sparse linear systems. This paper presents an asynchronous graph coloring heuristic well suited to distributed memory parallel computers. Experimental results obtained on an Intel iPSC/860 are presented, which demonstrate that, for graphs arising from finite element applications, the heuristic exhibits scalable performance and generates colorings usually within three or four colors of the best-known linear time sequential heuristics. For bounded degree graphs, it is shown that the expected running time of the heuristic under the P-RAM computation model is bounded by $EO(\log (n)/\log \log (n))$. This bound is an improvement over the previously known best upper bound for the expected running time of a random heuristic for the graph coloring problem.
Bacterial cellulose production by Acetobacter xylinum in a 50-L internal-loop airlift reactor (2000)

Bacterial cellulose (BC) production was realized in a batch cultivation of Acetobacter xylinum subsp. sucrofermentans BPR2001 in a 50-L internal-loop airlift reactor. When the bacterium was cultivated with air supply, 3.8 g/L of BC was produced after 67 hours. When oxygen-enriched gas was supplied, the concentration of BC was doubled and the production rate of BC was 0.116 g/L · h, which was two times higher than that of air-supplied culture and comparable to that in a mechanically agitated stirred-tank fermentor. Bacterial cellulose produced by the airlift reactor formed a unique ellipse pellet (BC pellet), different from the fibrous form which was produced in an agitated stirred-tank fermentor. The BC-pellet suspension was demonstrated to have a higher volumetric oxygen transfer coefficient than the fibrous BC suspension in a 50-L internal-loop airlift reactor. The mixing time of BC-pellet suspension in the airlift reactor was also shorter than that in water. © 2000 John Wiley & Sons, Inc. Biotechnol Bioeng 68: 345–352, 2000.
Learning to Pass Expectation Propagation Messages (2013)

Expectation Propagation (EP) is a popular approximate posterior inference algorithm that often provides a fast and accurate alternative to sampling-based methods. However, while the EP framework in theory allows for complex non-Gaussian factors, there is still a significant practical barrier to using them within EP, because doing so requires the implementation of message update operators, which can be difficult and require hand-crafted approximations. In this work, we study the question of whether it is possible to automatically derive fast and accurate EP updates by learning a discriminative model (e.g., a neural network or random forest) to map EP message inputs to EP message outputs. We address the practical concerns that arise in the process, and we provide empirical analysis on several challenging and diverse factors, indicating that there is a space of factors where this approach appears promising.
Monocyte activation by necrotic cells is promoted by mitochondrial proteins and formyl peptide receptors (2009)

Interactions between mitochondrial N-formyl peptides and FPR in the presence of other mitochondrial antigens (e.g., TFAM) contributes significantly to the activation of monocytes by necrotic cells.
Enhanced Li Adsorption and Diffusion on MoS<sub>2</sub> Zigzag Nanoribbons by Edge Effects: A Computational Study (2012)

By means of density functional theory computations, we systematically investigated the adsorption and diffusion of Li on the 2-D MoS2 nanosheets and 1-D zigzag MoS2 nanoribbons (ZMoS2NRs), in comparison with MoS2 bulk. Although the Li mobility can be significantly facilitated in MoS2 nanosheets, their decreased Li binding energies make them less attractive for cathode applications. Because of the presence of unique edge states, ZMoS2NRs have a remarkably enhanced binding interaction with Li without sacrificing the Li mobility, and thus are promising as cathode materials of Li-ion batteries with a high power density and fast charge/discharge rates.
Screening for autism in older and younger toddlers with the Modified Checklist for Autism in Toddlers (2008)

The Modified Checklist for Autism in Toddlers (M-CHAT) was used to screen younger (16-23 months) versus older (24-30 months) high- and low-risk toddlers. Refusal rates for follow-up interview showed no group differences, but parents of younger/low-risk children were more likely to refuse evaluation than parents of high-risk children. PPP for an ASD diagnosis was: younger/high-risk 0.79, older/high-risk 0.74, younger/low-risk 0.28, and older/low-risk 0.61, with PPP differing by age within the low-risk group. Most of the children in all groups, however, were diagnosed with a developmental disorder. Symptom severity generally did not differ among groups. Cognitive and adaptive measures showed minimal group differences. Therefore, older and younger toddlers had similar symptomatology and developmental delays; PPP for ASD is better at 24 than 18 months for low-risk children; however, these children are still highly likely to show a developmental disorder. Clinical decision making should balance early identification against the lower specificity of M-CHAT screening for the younger/low-risk group.
Brain MRI Lesion Load at 1.5T and 3T versus Clinical Status in Multiple Sclerosis (2009)

MRI at 3T may boost sensitivity and improve validity in MS brain lesion assessment.
Phrenic Stimulation (2009)

PS may seriously hinder CRT. A bipolar LV lead and cathode programmability are mandatory to avoid PS by changing the LV pacing vector at target sites for CRT. LV stability at target sites despite PS should also be pursued by these means. The automatic adjustment of LV pacing output is complementary in patients with a small PS-LV threshold difference.
Deficiency in ClC-3 Chloride Channels Prevents Rat Aortic Smooth Muscle Cell Proliferation (2002)

Recent growing evidence suggests that chloride (Cl-) channels are critical to the cell cycle. In cultured rat aortic vascular smooth muscle cells (VSMCs), we have previously found that Cl- channel blockers inhibit endothelin-1 (ET-1)-induced cell proliferation. The present study was designed to further identify the specific Cl- channels responsible for VSMC proliferation. Due to the lack of a specific blocker or opener of any known Cl- channels, we used the antisense strategy to investigate the potential role of ClC-3, a member of the voltage-gated Cl- channel gene family, in cell proliferation of cultured rat aortic VSMCs. With [3H]-thymidine incorporation and immunoblots, we found that ET-1-induced cell proliferation was parallel to a significant increase in the endogenous expression of ClC-3 protein. Transient transfection of rat aortic VSMCs with antisense oligonucleotide specific to ClC-3 caused an inhibition in ET-1-induced expression of ClC-3 protein and cell proliferation of VSMCs in the same concentration- and time-dependent pattern, whereas sense and missense oligonucleotides resulted in no effects on ClC-3 protein expression and cell proliferation. These results strongly suggest that ClC-3 may be the Cl- channel involved in VSMC proliferation and thus provide compelling molecular evidence linking a specific Cl- channel to cell proliferation.

Localization of I-131-labeled tumor-specific monoclonal antibody in the tumor-bearing BALB/c mouse. (1980)

One of the most frequent indications for patient imaging is the need to establish the presence or absence of malignant disease. Considerable effort has been invested in attempting to develop tumor-specific radiopharmaceuticals. We report the localization of an iodine-131-labeled, hybridoma-derived monoclonal antibody in the MH-15 teratocarcinoma-bearing BALB/c mouse. Tumor-to-muscle and tumor-to-blood ratios of 150:1 and 15:1, respectively, were observed at 5 days after administration of 15 microCi of labeled antibody. The relationship between the optimal imaging time and localization kinetics is discussed.
Orderly arranged NLO materials on exfoliated layered templates based on dendrons with alternating moieties at the periphery (2013)

Nonlinear optical dendrons with alternating terminal groups of the stearyl group (C18) and chromophore were prepared through a convergent approach. These chromophore-containing dendrons were used as the intercalating agents for montmorillonite via an ion-exchange process. An orderly exfoliated morphology is obtained by mixing the dendritic structure intercalated layered silicates with a polyimide. As a result, optical nonlinearity, i.e. the Pockels effect was observed for these nanocomposites without resorting to the poling process. EO coefficients of 9–22 pm V−1 were achieved despite that relatively low NLO densities were present in the nanocomposites, particularly for the samples comprising the dendrons with alternating moieties. In addition, the hedging effects of the stearyl group on the self-alignment behavior, electro-optical (EO) coefficient and temporal stability of the dendron-intercalated montmorillonite/polyimide nanocomposites were also investigated.
Modeling complex flows for worst-case execution time analysis (2002)

Knowing the worst-case execution time (WCET) of a program is necessary when designing and verifying real-time systems. The WCET depends both on the program flow (like loop iterations and function calls), and on hardware factors like caches and pipelines. In this paper, we present a method for representing program flow information that is compact while still being strong enough to handle the types of flow previously considered in WCET research. We also extend the set of representable flows compared to previous research. We give an algorithm for converting the flow information to the linear constraints used in calculating a WCET estimate in our WCET analysis tool. We demonstrate the practicality of the representation by modeling the flow of a number of programs, and show that execution time estimates can be made tighter by using flow information.
High Relaxation Oscillation Frequency (beyond 10 GHz) of GaAlAs Multiquantum Well Lasers (1985)

Direct modulation bandwidth of GaAlAs multiquantum well (MQW) lasers with 5 nm-thick GaAs wells was investigated. It was experimentally found that relaxation oscillation frequency of MQW lasers is beyond 10 GHz, which is twice that of double heterostructure lasers. This result was confirmed by theoretical analysis.
Distinct Genomic Alterations in Prostate Cancers in Chinese and Western Populations Suggest Alternative Pathways of Prostate Carcinogenesis (2010)

Prostate cancer is significantly more common in Western men than in Asian men, but the basis for this difference remains unknown. Because genomic studies of Asian prostate cancer are very limited, we used a genome-wide approach to reveal the genomic alterations in Chinese prostate cancers. We found a significant reduction in the frequency of certain somatic genomic changes that are commonly found in Western prostate cancers, including the 21q22.2-22.3 deletion, which involves the TMPRSS2:ERG fusion gene, and 10q deletion, which causes PTEN inactivation. Array results were confirmed by PCR-based molecular copy-number counting in selected samples. The different frequencies of these genomic changes were further evaluated by fluorescent in situ hybridization and immunohistochemistry analyses of tissue microarray samples. These alterations might be key genetic changes underlying the regional/ethnic difference in clinical incidence and might be induced by specific environmental and/or genetic risk factors that Western men are exposed to. Our findings suggest that tumors arise in Western and Chinese populations by alternative pathogenetic mechanisms.
Restriction of 480/270-kD Ankyrin G to Axon Proximal Segments Requires Multiple Ankyrin G-specific Domains (1998)

AnkyrinG (-/-) neurons fail to concentrate voltage-sensitive sodium channels and neurofascin at their axon proximal segments, suggesting that ankyrinG is a key component of a structural pathway involved in assembly of specialized membrane domains at axon proximal segments and possibly nodes of Ranvier (Zhou, D., S. Lambert, D.L. Malen, S. Carpenter, L. Boland, and V. Bennett, manuscript submitted for publication). This paper addresses the mechanism for restriction of 270-kD ankyrinG to axon proximal segments by evaluation of localization of GFP-tagged ankyrinG constructs transfected into cultured dorsal root ganglion neurons, as well as measurements of fluorescence recovery after photobleaching of neurofascin- GFP-tagged ankyrinG complexes in nonneuronal cells. A conclusion is that multiple ankyrinG-specific domains, in addition to the conserved membrane-binding domain, contribute to restriction of ankyrinG to the axonal plasma membrane in dorsal root ganglion neurons. The ankyrinG-specific spectrin-binding and tail domains are capable of binding directly to sites on the plasma membrane of neuronal cell bodies and axon proximal segments, and presumably have yet to be identified docking sites. The serine-rich domain, which is present only in 480- and 270-kD ankyrinG polypeptides, contributes to restriction of ankyrinG to axon proximal segments as well as limiting lateral diffusion of ankyrinG-neurofascin complexes. The membrane-binding, spectrin-binding, and tail domains of ankyrinG also contribute to limiting the lateral mobility of ankyrinG-neurofascin complexes. AnkyrinG thus functions as an integrated mechanism involving cooperation among multiple domains heretofore regarded as modular units. This complex behavior explains ability of ankyrinB and ankyrinG to sort to distinct sites in neurons and the fact that these ankyrins do not compensate for each other in ankyrin gene knockouts in mice.
Cell-mediated immune response of human lymphocytes to influenza A/USSR (H1N1) virus infection (1980)

Cell-mediated immunity to influenza A/USSR (H1N1) virus was assessed by measuring transformation response and interferon production by Ficoll-Hypaque-purified peripheral blood lymphocytes from children and adults. Lymphocyte transformation was found to be related to the individual's previous experience with H1N1 influenza virus. Lymphocyte cultures, obtained from adults who had their last contact with the H1N1 virus over 20 years ago, were able to transform when incubated with H1N1 influenza antigens. This response suggests that influenza virus can induced long-term cell-mediated immunity for periods of at least 20 years. Interferon produced by stimulated lymphocytes was found to be unrelated to previous contact with influenza H1N1 virus; seronegative as well as seropositive individuals were capable of producing interferon in response to viral antigens. The interferon produced was type I.
