Poly(imide-siloxane) segmented copolymer structural adhesives prepared by bulk and solution thermal imidization (1988)

The improved properties that have been demonstrated through thermal solution imidization in the case of polyimides and poly(imide-siloxane) segmented copolymers suggests significant potential for application of these new materials. Specifically, the enhancement in solubility, moisture reduction, and processability observed through this solution technique is quite dramatic. Previous work has shown that the presence of low amounts of siloxane does not detract significantly from the lap shear strength of these materials to titanium in the case of bulk thermal imidization synthesis. In addition, the siloxane incorporation results in the added advantage of resistance to hot, wet environments. This added durability is presumably due to the hydrophobic siloxane segments preventing the uptake of water at the critical interphase between the adhesive and the adherend. This paper discusses the extension of this work to the solution imidization synthesis technique recently developed in our laboratory. Results dealing with the absolute bond strengths as well as durability and failure surface analysis will be presented.
Nuclear Magnetic Resonance in B2O3–H2O Glasses and Boric Acids (1960)

The class of materials B2O3–H2O has been investigated over the range B2O3 to B2O3·3H2O. This includes ``dry'' glassy B2O3, ``wet'' glassy boron oxide of approximate composition B2O3·½H2O, monoclinic and orthorhombic forms of metaboric acid, B2O3·H2O, and triclinic orthoboric acid, B2O3·3H2O. The nuclear quadrupole interaction of the B11 isotope was measured and comparisons of the structures are made on the basis of this interaction. It is shown that all substances contain similar planar BO3 triangular units. The presence of O–H–O hydrogen bonds, as in B2O3·3H2O, has a minor effect on the boron nuclear quadrupole interaction. It is concluded that BO4 tetrahedral units exist in several of the wet glass samples as well as in monoclinic metaboric acid.

Refractive index change during exposure for 193-nm chemically amplified resists (1999)

Some of the important areas to be improved for lithography simulation are getting correct exposure parameters and determining the change of refractive index. It is known that the real and imaginary refractive indices are changed during exposure. We obtained these refractive index changes during exposure for 193 nm chemically amplified resists. The variations of the transmittance as well as the resist thickness were measured during ArF excimer laser exposure. We found that the refractive index change is directly related to the concentration of the photo acid generator and de-protected resin. It is important to know the exact values of acid concentration from the exposure parameters since a small difference in acid concentration magnifies the variation in the amplified de-protection during post exposure bake. We developed and used a method to extract Dill ABC exposure parameters for 193 nm chemically amplified resist from the refractive index change upon exposure.

Thrombocytopenia and bleeding in dental procedures of patients with Gaucher disease (2011)

The risk of bleeding during dental procedures may be increased in patients with Gaucher disease. We aimed to evaluate potential coagulation and platelet function abnormalities and targeted therapy accordingly. Patients with type 1 Gaucher disease who were treated at the Oral and Maxilo-Facial surgery clinic at Sheba Medical Center between 2003 and 2010 comprised the study cohort. Data collected included disease history, enzyme treatment, platelet counts, dental therapy and outcome. Bleeding was defined as excessive bleeding during or immediately following procedure. Coagulation studies and platelet function tests including aggregometry were performed on all patients. Dental procedures (n = 14, including eight teeth extractions, two crown lengthening procedures, one cyst enucleation and three deep dental scaling) of seven patients were studied. Mean platelet count prior to procedure was 73 K ± 14.8 mm(3). Patients bleeding risk score was calculated according to previous history of bleeding tendency, degree of thrombocytopenia, presence of comorbid coagulopathy and the type of dental procedure. Two patients with highest risk score received prophylactic platelet transfusions, three patients (medium-risk) received DDAVP preprocedure and all received systemic tranexamic acid, which was the only systemic therapy for low-risk patients. Meticulous surgical local haemostasis was applied. No excessive intra-operative or postoperative bleeding occurred. Patients with Gaucher disease who have thrombocytopenia and abnormal platelet function tests may be safely treated if meticulous haemostasis is applied along with systemic therapy as required. Platelet transfusions are not mandatory and should be applied considering the procedure-related risk and the patient's calculated haematological risk for bleeding.
One-dimensional heterostructural metallodielectric photonic band gap material for the modification of emission spectrum of BaF2 scintillator (2004)

One-dimensional metallodielectric heterostructural photonic band gap (PBG) material is designed to reach high transmittance band in short wavelength, broad and deep forbidden band in long wavelength, especially sharp cutoff edge between the transmission and forbidden bands. The designed PBG material is applied to modify the emission spectrum of a BaF2 scintillator and is proved to be adequate to suppress the slow component of the scintillation light. The suppression ratio of the slow to the fast component reaches 28dB with a tolerable attenuation of the fast component.

Preparation of α‐substituted α‐amino acids of high enantiomeric purity (1992)

Abstract Racemic 5,5‐dialkyl hydantoins derived from ketones are resolved by preparative liquid chromatography as the diastereomeric 1‐carboxamide derivatives afforded by the reaction with optically pure configurationally known α‐phenylethyl isocyanate. Hydrolysis of the resolved diastereomers affords α‐substituted α‐amino acids of high enantiomeric purity. The synthetic route is short, overall yields are high, and the absolute configuration of the amino acid enantiomers may be deduced from the chromatographic and NMR properties of the diastereomers. © 1992 Wiley‐Liss, Inc.
653. The Controlled Transgene Expression in Oncolytic Adenoviral Vectors with Major Late Promoter for Therapy of Cancer (2006)

Virotherapy with oncolytic viruses is based on the use of tumor specific replicating virus. The oncolytic viruses have capacity for destruction of tumors and produce new infectious virus particles that will infect surrounding tumor cells and spread throughout the tumor. They have been used as potential vectors to express therapeutic genes in tumor cells. In order to allow transgene expression in the controlled and predicted manner, we generated oncolytic adenoviral vectors with transgene driven by major late promoter (MLP). The reporter gene HcRed and therapeutic genes Mda7/IL-24 and TRAIL have been incorporated into this vector. Our data showed that transgene expression was not detectable in the first hours after infection. The high level of transgene expression was found at 24 and 48 hours after infection. The expression level of transgenes was dramatic higher in tumor cells than normal cells infected with our vectors. Our results supported that high level of transgene expression in tumor cells was due to the viral replication. The vector carrying therapeutic genes have strong cytotoxicity to tumor cells. Our data indicated that oncolytic adenovirus could serve as potent vectors for delivery of therapeutic gene into tumor cells.
[An oral enteritis-vaccine composed of twelve heat inactivated Enterobacteriaceae. 1. Communication: Theoretical and epidemiological considerations (author's transl)]. (1979)

The infectious diseases of the human intestinal tract which are caused by bacteria must be distinguished into two groups on account of their different pathogenesis: the cyclic infections (typhoid fever, parathyphoid fever) and the local infections (cholera, dysentery, Salmonella enteritis, dyspepsia coli infections). The local infections of the intestine do not cause a systemic but only a local immunity of the intestinal mucosa. It is necessary therefore to induce local immunity as active immunoprophylaxis by orally administering inactivated antigens. The twelve-fold enteritis vaccine consists of full antigens of 6 Salmonella strains, 2 Shigella strains, and 4 enteropathogenic coli strains pretreated by heat-inactivation (3 min/100 degrees C). The following should be considered as indication to effect active immunoprophylaxis against enteritis: Travelling into tropical and subtropical countries, people in emergency areas, children in developing countries, workers in food industries, secondary hospital infections, and carriers. The active mouse protection test revealed that oral immunization with enterobacteriaceae does not only deliver the well-known specific effect but also a non-specific effect which included the protection against other related enterobacteriaceae. Moreover, the specific component of the combined vaccine is enhanced by heterologous components. The resulting synergism or the adjuvantal effect, respectively, allows to employ a relatively limited number of germs which are selected on the basis of high pathogenicity, good immunogenicity, and great frequency. The first field trial with the twelve-fold vaccine was completed successfully: Following an infection with Salmonella which affected the employees of a fowl slaughtery, eight different species could be demonstrated; the above described polyvalent vaccine was orally administered and proved to be successful. The latter case clearly demonstrates the fast-acting effect of the vaccine on account of the heterologous bacterial antigens contained therein. 51 out of 60 Salmonella carriers excreted germs of a different antigen pattern not contained in the vaccine. However, the good results obtained showed that the species chosen for the vaccine were still sufficiently effective to cover the wide spectrum of other species of related enterobacteriaceae.
Potential biomarkers for bipolar disorder (2017)

Bipolar disorder (BD) is a severe, recurrent mood disorder, associated with a significant morbidity and mortality, with high rates of suicides and medical comorbidities. There is a high risk of mood disorders among the first-degree relatives of patients with BD. In the current clinical practice, the diagnosis of BD is made by history taking, interview and behavioural observations, thereby lacking an objective, biological validation. This approach may result in underdiagnosis, misdiagnosis and eventually poorer outcomes. Due to the heterogeneity of BD, the possibility of developing a single, specific biomarker is still remote; however, there is a set of promising biomarkers which may serve as predictive, prognostic or treatment markers in the future. The review presents a critical appraisal and update on some of the most promising candidates for biomarkers, namely, neuroimaging markers, peripheral biomarkers and genetic markers, including a brief discussion on cognitive endophenotypes as indicative of genetic risk. The lessons learnt from other fields and specialties in medicine need to be applied to psychiatry to translate the knowledge from ‘bench to bedside’ by means of clinically useful biomarkers. Overall, the biomarkers may help in pushing the shift towards personalized medicine for psychiatric patients.

Specification Uncertainty and Model Averaging (1997)

Theory: Data analysts sometimes report (and more often produce) results from many alternative models with different explanatory variables, functional forms, observations, or exogeneity assumptions. Classical statistical theory is ill-suited to make sense of this practice. Hypotheses: Bayesian statisticians have recently proposed a coherent procedure for taking account of specification uncertainty by averaging results from a variety of different model specifications. The model-averaging procedure has the general effect of discounting evidence derived from elaborate specification searches, especially when alternative models produce markedly different results. Methods: I describe the model-averaging procedure, and illustrate its application using examples drawn from a controversy in comparative political economy between Lange and Garrett (1985, 1987) and Jackman (1987), and from the work of Erikson, Wright, and McIver (1993) on public opinion and policy in the American states. In addition, I propose two classes of reference that might usefully supplement the uniform model typically adopted in model averaging-a dummy-resistant prior for dealing with outlier observations, and a family of search-resistant priors for representing sequential specification searches. Results: The model-averaging procedure seems to offer a convenient approximation to full-blown Bayesian analysis in typical social science settings. It is simple to implement, and uses the variety of alternative model specifications already being produced by data analysts to shed some useful light on the inferential implications of specification uncertainty.
Pharmacology of benzodiazepine receptors: an update. (1994)

Benzodiazepine receptors are allosteric modulatory sites on GABAA receptors. GABAA receptors are probably composed of five protein subunits, at least some of which belong to different subunit classes. So far six alpha-, four beta-, three gamma-, and delta- and two rho = p subunits of GABAA receptors have been identified. A large number of different subunit combinations, each of which will result in a GABAA receptor with distinct electrophysiological and pharmacological properties, are therefore possible. Many compounds from different chemical classes which are able to bind to benzodiazepine receptors have been identified. Depending on their individual efficacy, binding of these compounds either enhances, reduces or does not influence GABAergic transmission. However, the individual efficacy of the benzodiazepine receptor ligands changes with the subunit composition of the GABAA receptor. The investigation of the regional distribution, subunit composition and pharmacology of GABAA receptors will result in the development of new and more selective compounds for psychiatry.
Reasonable Grasping Based on Hierarchical Decomposition Models of Unknown Objects (2018)

Reasonable grasping for unknown objects is an interesting and important problem for autonomous robots in unstructured environment. Current grasping methods for unknown objects mostly focus on precision and stability. Until now there are few specific studies or reports describing reasonable grasp of unknown objects for service robots such as home service robots and nursing robots. In the paper we proposed a reasonable grasping method for unknown objects based on hierarchical decomposition point cloud models using a vision sensor. As a complex task, vision-based grasp is composed of a series solution of a mixture of subproblems. Therefore, we adopt an improved superquadrics fitting algorithm with the improved cuckoo search strategy (S-ICS) to achieve restoration and segmentation of incomplete point cloud data of unknown objects in a single visual angle. Then a reasonable region decision method based on hierarchical decomposition models is proposed to evaluate the reasonableness of grasped positions of unknown objects. Finally, we use a simulation to verify the effectiveness of the proposed method. Moreover, we also perform an extensive real-world grasping experiment on a set of unknown objects in daily use. The results also verify the effectiveness of our approach.
Chemical vapor deposition of copper from Cu+1 precursors in the presence of water vapor (1993)

Copper films have been deposited by low pressure chemical vapor deposition from mixtures of the Cu+1 precursor copper hexafluoroacetylacetonate vinyltrimethylsilane and water vapor. The addition of water vapor at the optimum concentration more than doubles the deposition rate and substantially reduces the nucleation time without adversely affecting the copper film resistivity, but excess amounts of water vapor significantly increase the copper resistivity. Auger electron spectroscopy analysis detects no impurities in copper films deposited under optimum water conditions, but detects oxygen in films deposited under excess water conditions, suggesting copper oxide formation.
Tryptophan in Membrane-Active Synthetic Antimicrobials (2017)

<fig fig-type="abstract"><graphic mimetype="image" xlink:href="jerp-16-25-ga.tif" xmlns:xlink="http://www.w3.org/1999/xlink">Herein, we summarize the background data that has led to a new class of antimicrobial amphiphiles and present recent results showing reversal of resistance to antibiotics in an Escherichia coli strain incorporating a tetracycline-selective efflux pump. In addition, two types of amphiphiles that show antibiotic potency enhancement or resistance reversal are discussed, along with our knowledge on the evolution that led to the active structures. One family is based on macrocyclic crown polyethers, which are known to insert into both liposomal and bacterial bilayers; these compounds are termed as hydraphiles and consist of three diazacrown rings linked by alkyl spacers and terminated by benzyl groups. In contrast, the second type of amphiphiles use tryptophans as the terminal, membrane anchoring residues; in this group of amphiphiles, two tryptophans are connected by alkyl chains or aryl groups. In both cases, however, the antibacterial activity of certain members of each family was apparent. Further, the amphiphiles have been shown to act as adjuvants that increase the potency of such antimicrobials as tetracycline and even to have re-sensitized a tetracycline-resistant E. coli strain to the antibiotic.
Seroreactivity Against Aqueous-Soluble and Detergent-Soluble Retinal Proteins in Posterior Uveitis (2011)

Healthy control patients exhibited a significantly higher level of background autoantibody activity against retinal proteins than previously reported. Antibody activity in healthy controls was primarily directed against membrane-bound retinal proteins, whereas in patients with pathologic retinal conditions, antibodies targeting nonmembrane-bound retinal proteins predominate.
