The structural and functional interrelationships of muscarinic acetylcholine receptor subtypes (1989)

Molecular cloning of the genes encoding the muscarinic acetylcholine receptors has shown that receptor subtypes classified on the basis of pharmacological properties are related polypeptides encoded by distinct genes. These studies have also revealed the existence of novel muscarinic receptor subtypes. Functional analysis of each of the subtypes expressed in mammalian cells indicates that the different subtypes activate distinct biochemical pathways, a finding that explains the tissue-specific physiological response elicited by the neurotransmitter, acetylcholine.
Capillary zone electrophoresis for the characterization of latex particles (2001)

Capillary zone electrophoresis (CZE) was applied to the separation of acrylic styrene copolymer emulsion particles. Fast separations could be performed on samples containing chemically identical latex particles of different size, as well as on samples with particles of the same size but differing in chemical composition. The developed method was also used for the analysis of water soluble fractions of urethane dispersions. Additionally, the physical interaction between different particles (e.g., acrylic and urethane particles) could be studied using this method. The separation mechanism is based on the zeta potential of the particles and the relaxation effect under the applied analytical conditions.
Energy-dependent inactivation of citrate lyase in Enterobacter aerogenes (1977)

Enterobacter aerogenes was grown in continous culture with ammonia as the growth-limiting substrate, and changes in citrate lyase and citrate synthase activities were monitored after growth shifts from anaerobic growth on citrate to aerobic growth on citrate, aerobic growth on glucose, anaerobic growth on glucose, and anaerobic growth on glucose plus nitrate. Citrate lyase was inactivated during aerobic growth on glucose and during anaerobic growth with glucose plus nitrate. Inactivation did not occur during anaerobic growth on glucose, and as a result of the simultaneous presence of citrate lyase and citrate synthase, growth difficulties were observed. Citrate lyase inactivation consisted of deacetylation of the enzyme. The corresponding deacetylase could not be demonstrated in cell extracts, and it is concluded that, as in a number of other inactivations, electron transport to oxygen or nitrate was required for inactivation.
Efficient Synthesis of Regioisomerically Pure Bis(trifluoromethyl)-Substituted 3,4,9,10-Perylene Tetracarboxylic Bis(benzimidazole) (2009)

By a new strategy, two trifluoromethyl groups were efficiently introduced to highly insoluble n-type semiconductor 3,4,9,10-perylene tetracarboxylic bis(benzimidazole) (PTCBI), and for the first time we obtained three pure regioisomers of bis(trifluoromethyl)-substituted PTCBI, whose optical properties are different from one another.
Limitations of yeast surface display in engineering proteins of high thermostability (2006)

Engineering proteins that can fold to unique structures remains a challenge. Protein stability has previously been engineered via the observed correlation between thermal stability and eukaryotic secretion level. To explore the limits of an expression-based approach, variants of the highly thermostable three-helix bundle protein alpha3D were studied using yeast surface display. A library of alpha3D mutants was created to explore the possible correlation of protein stability and fold with expression level. Five efficiently expressed mutants were then purified and further studied biochemically. Despite their differences in stability, most mutants expressed at levels comparable with that of wild-type alpha3D. Two other related sequences (alpha3A and alpha3B) that form collapsed, stable molten globules but lack a uniquely folded structure were similarly expressed at high levels by yeast display. Together these observations suggest that the quality control system in yeast is unable to discriminate between well-folded proteins of high stability and molten globules. The present study, therefore, suggests that an optimization of the surface display efficiency on yeast may yield proteins that are thermally and chemically stable yet are poorly folded.
Purificación y santidad: Una perspectiva de «comunión» según San Gregorio de Nacianzo. Aproximación a partir del discurso 40 (2017)

Para san Gregorio de Nacianzo el combate cristiano por la purificación y la santidad es un verdadero lugar de comunión inscrito en una dinámica existencial. Cristo es el Puro y el Santo, en quien resplandece la Gloria de la Trinidad, pero todo hombre por el bautismo (primera iluminación) es puesto en tensión hacia la recepción, cada vez más intensa, de la Luz divina, La calidad de la lucha espiritual (segunda iluminación) es el lugar de verificación de este deseo y tensión por la santidad, y ello posibilitado por la gracia de Cristo y la regeneración obrada por el Espíritu.
Congenital Heterozygous Plasminogen Deficiency Associated with a Severe Thrombotic Tendency (1986)

Heterozygous plasminogen deficiency was found in 2 patients (mother and daughter). The mother, aged 55 years, was symptomatic while the daughter, aged 10 years, was asymptomatic so far. The thrombotic tendency presented by the proposita (mother) was severe and included recurrent superficial, portal, mesenteric, subclavian thrombophlebitis. No arterial thrombosis was noted. Oral anticoagulants have been of some benefit. The main laboratory features were: plasminogen activity about 50% of normal in two amidolytic methods and in a caseinolytic method. Plasminogen antigen was also about 50% of normal using electroimmunoassay and radial immunodiffusion. Crossed immunoelectrophoresis revealed a normal, even though reduced pattern, thus excluding dysplasminogenemia. Routine coagulation tests were negative. Euglobulin lysis time, fibrinogen level and fibrinogen degradation products (FDP) were within normal limits. Antithrombin III, protein C and protein S were also within normal limits.
Electrically controlling single-spin qubits in a continuous microwave field (2015)

Large-scale quantum computers must be built upon quantum bits that are both highly coherent and locally controllable. We demonstrate the quantum control of the electron and the nuclear spin of a single (31)P atom in silicon, using a continuous microwave magnetic field together with nanoscale electrostatic gates. The qubits are tuned into resonance with the microwave field by a local change in electric field, which induces a Stark shift of the qubit energies. This method, known as A-gate control, preserves the excellent coherence times and gate fidelities of isolated spins, and can be extended to arbitrarily many qubits without requiring multiple microwave sources.
Isolation, NMR Spectral Analysis and Hydrolysis Studies of a Hepta Pyranosyl Diterpene Glycoside from Stevia rebaudiana Bertoni (2013)

From the commercial extract of the leaves of Stevia rebaudiana Bertoni, a minor steviol glycoside, 13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-[(2-O-(3-O-β-D-glucopyranosyl-α-L-rhamnopyranosyl)-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl) ester] (1); also known as rebaudioside O having seven sugar units has been isolated. Its structural characterization has been achieved by the extensive 1D (1H and 13C), and 2D NMR (COSY, HMQC, HMBC) as well as mass spectral data. Further, hydrolysis studies were performed on rebaudioside O using acid and enzymatic methods to identify aglycone and sugar residues in its structure as well as their configurations.
Voice Conversion from Unaligned Corpora using Variational Autoencoding Wasserstein Generative Adversarial Networks (2017)

Building a voice conversion (VC) system from non-parallel speech corpora is challenging but highly valuable in real application scenarios. In most situations, the source and the target speakers do not repeat the same texts or they may even speak different languages. In this case, one possible, although indirect, solution is to build a generative model for speech. Generative models focus on explaining the observations with latent variables instead of learning a pairwise transformation function, thereby bypassing the requirement of speech frame alignment. In this paper, we propose a non-parallel VC framework with a variational autoencoding Wasserstein generative adversarial network (VAW-GAN) that explicitly considers a VC objective when building the speech model. Experimental results corroborate the capability of our framework for building a VC system from unaligned data, and demonstrate improved conversion quality.
Analysis of MHC Class II Genes in the Susceptibility to Lupus in New Zealand Mice (1999)

Hybrids of New Zealand Black (NZB) and New Zealand White (NZW) mice spontaneously develop a disease similar to human systemic lupus erythematosus. MHC and non-MHC genes contribute to disease susceptibility in this murine model. Multiple studies have shown that the NZW H2z locus is strongly associated with the development of lupus-like disease in these mice. The susceptibility gene(s) within H2z is not known, but different lines of evidence have pointed to class II MHC genes, either H2-E or H2-A (Ez or Az in NZW). Recent studies from our laboratory showed that Ez does not supplant H2z in the contribution to lupus-like disease. In the present work we generated C57BL/10 (B10) mice transgenic for Aaz and Abz genes (designated B10.Az mice) and used a (B10.Az x NZB)F1 x NZB backcross to assess the contributions of Az genes to disease. A subset of backcross mice produced high levels of IgG autoantibodies and developed severe nephritis. However, no autoimmune phenotype was linked to the Az transgenes. Surprisingly, in the same backcross mice, inheritance of H2b from the nonautoimmune B10 strain was strongly linked with both autoantibody production and nephritis. Taken together with our previous Ez studies, the present work calls into question the importance of class II MHC genes for lupus susceptibility in this model and provides new insight into the role of MHC in lupus-like autoimmunity.
Anaerobic regulation of pyruvate formate-lyase from Escherichia coli K-12 (1988)

The anaerobic regulation of the gene encoding pyruvate formate-lyase from Escherichia coli was investigated. Expression of a pfl'-'lacZ protein fusion demonstrated that the gene is subject to a 12-fold anaerobic induction which can be stimulated a further 2-fold by the addition of pyruvate to the growth medium. Construction of a strain deleted for pfl verified that either pyruvate or a metabolite of glycolysis functions as an inducer of pfl gene expression. Complete anaerobic induction required the presence of a functional fnr gene product. However, the dependence was not absolute since a two- to threefold anaerobic induction could still be observed in an fnr mutant. These results could be confirmed immunologically by analyzing the levels of pyruvate formate-lyase protein present in cells grown under various conditions. It was also shown that pfl'-'lacZ expression was partially repressed by nitrate and that this repression was mediated by the narL gene product.
New Biomimetic Constructs for Improved In Vivo Circulation of Superparamagnetic Nanoparticles (2008)

Superparamagnetic iron oxide nanoparticles (SPIOs) have been produced and used as a potent and versatile contrast media for magnetic resonance imaging (MRI). Despite a number of efforts to improve their surface chemistry and biocompatibility, the SPIOs half life in blood circulation is very short and they are rapidly taken up by the reticuloendothelial system (RES). In this paper we describe a new method that permits to avoid the rapid clearance of SPIOs. Nanoparticles are made biocompatible by encapsulation into autologous red blood cells. These biomimetic constructs preserve the main properties of the cells that escape RES clearance as well as the properties of the nanoparticles that perform even better than in blood suspension with reduced T2*. These SPIO-loaded RBCs are promising intravascular imaging contrast agents and could also be addressed to selected body compartments by an external magnetic field.

Comparing Platforms for C. elegans Mutant Identification Using High-Throughput Whole-Genome Sequencing (2008)

In conclusion, whole-genome sequencing conducted by either platform is a viable approach for the identification of single-nucleotide variations in the C. elegans genome.
Antitumor immunity induced by photodynamic therapy with aluminum disulfonated phthalocyanines and laser light (1994)

Photodynamic therapy (PDT) is systemic administration of tumor localizing photosensitizers and subsequent irradiation with light of the appropriate wavelength. The combination of drug uptake in malignant tissues and selective delivery of laser-generated light provides effective therapy, with efficient tumor cytotoxicity and minimal normal tissue damage. There have been few studies of the effects of photoactivated photosensitizers on the host immune response. Since immunity is important in the control of tumor growth and spread, we have examined, in our laboratory, the effects of photoactivated phthalocyanines on the antitumor immune response. Immunosuppressed and normal mice bearing the MS-2 fibrosarcoma treated with 5 mg/kg of aluminum disulfonated phthalocyanine (AIS2Pc) and then the tumor mass exposed to laser light (100 mW/cm2 x 10 min) or treated with surgical excision of the tumor survived indefinitely, with no difference between the different groups. The survivors, tumor-free 100 days after the treatment modalities described above, were rechallenged with the parental MS-2. Some groups of surviving animals were immunosuppressed with cyclophosphamide before the injection of the tumor. Resistance to rechallenge was evidenced only in normal surviving animals cured by PDT, while the immunodepressed surviving animals and animals cured by surgery died of tumor. Finally, mice, cured by PDT and tumor-free, rechallenged with L1210 and P388 murine leukemias did not survive. These results suggest that a potential and specific 'antitumor immunity' is induced by PDT with photoactivated AIS2Pc.
Endoplasmic Reticulum Export, Subcellular Distribution, and Fibril Formation by Pmel17 Require an Intact N-terminal Domain Junction (2010)

Pmel17 is a melanocyte/melanoma-specific protein that subcellularly localizes to melanosomes, where it forms a fibrillar matrix that serves for the sequestration of potentially toxic reaction intermediates of melanin synthesis and deposition of the pigment. As a key factor in melanosomal biogenesis, understanding intracellular trafficking and processing of Pmel17 is of central importance to comprehend how these organelles are formed, how they mature, and how they function in the cell. Using a series of deletion and missense mutants of Pmel17, we are able to show that the integrity of the junction between the N-terminal region and the polycystic kidney disease-like domain is highly crucial for endoplasmic reticulum export, subcellular targeting, and fibril formation by Pmel17 and thus for establishing functional melanosomes.
The effect of deprenyl and levodopa on the progression of Parkinson's disease (1995)

We have performed a 14-month, prospective, randomized, double-blind, placebo-controlled study to evaluate the effect of deprenyl and levodopa/carbidopa (Sinemet) on the progression of signs and symptoms in patients with mild Parkinson's disease (PD). One hundred one untreated PD patients were randomly assigned to one of the following four treatment groups: Group I, deprenyl + Sinemet; Group II, placebo-deprenyl + Sinemet; Group III, deprenyl + bromocriptine; and Group IV, placebo-deprenyl + bromocriptine. The final visit was performed at 14 months, i.e., 2 months after withdrawal of deprenyl or its placebo and 7 days after withdrawal of Sinemet or bromocriptine. Deterioration in Unified Parkinson's Disease Rating Score (UPDRS) between untreated baseline and final visits was used as an index of disease progression. Placebo-treated patients deteriorated by 5.8 +/- 1.4 points, while deprenyl-treated patients deteriorated by 0.4 +/- 1.3 points (p < 0.001). This effect was sufficiently powerful that a significant deprenyl effect could be detected in the subgroup of 41 patients randomized to Sinemet (p < 0.01) as well as in the 23 patients who completed a 14-day washout of Sinemet or bromocriptine (p < 0.05). No difference in the extent of deterioration was detected in patients randomized to Sinemet versus bromocriptine. This study demonstrates that deprenyl attenuates deterioration in UPDRS score in patients with early PD. These findings are not readily explained by the drug's symptomatic effects and are consistent with the hypothesis that deprenyl has a neuroprotective effect.
Efficient Rate-Compatible Puncturing Scheme for Low-Density Parity-Check Codes (2011)

An efficient rate-compatible (RC) puncturing scheme for LDPC codes is proposed, which tries to distribute the punctured bits as evenly as possible while maximizing the number of 1-SR nodes in Tanner graph. The puncturing scheme can produce RC LDPC with rates ranging from the mother code rate through even 1. Simulation results show that the new puncturing method is superior to random puncturing and the method in [2].
Results of imatinib mesylate therapy in patients with refractory or recurrent acute myeloid leukemia, high‐risk myelodysplastic syndrome, and myeloproliferative disorders (2003)

Within these small subgroups of disease types, single-agent imatinib did not achieve a significant clinical response among patients with AML, MDS, atypical CML, or CMML without PDGF-R fusion genes. Preliminary data on polycythemia vera are promising and deserve further investigation. Responses among myelofibrosis patients were minor. Therefore, a combination treatment regimen including imatinib may be more effective.
Chronic stress impairs prefrontal cortex-dependent response inhibition and spatial working memory. (2012)

Chronic stress leads to neurochemical and structural alterations in the prefrontal cortex (PFC) that correspond to deficits in PFC-mediated behaviors. The present study examined the effects of chronic restraint stress on response inhibition (using a response-withholding task, the fixed-minimum interval schedule of reinforcement, or FMI), and working memory (using a radial arm water maze, RAWM). Adult male Sprague-Dawley rats were first trained on the RAWM and subsequently trained on FMI. After acquisition of FMI, rats were assigned to a restraint stress (6h/d/28d in wire mesh restrainers) or control condition. Immediately after chronic stress, rats were tested on FMI and subsequently on RAWM. FMI results suggest that chronic stress reduces response inhibition capacity and motivation to initiate the task on selective conditions when sucrose reward was not obtained on the preceding trial. RAWM results suggest that chronic stress produces transient deficits in working memory without altering previously consolidated reference memory. Behavioral measures from FMI failed to correlate with metrics from RAWM except for one in which changes in FMI timing imprecision negatively correlated with changes in RAWM working memory errors for the controls, a finding that was not observed following chronic stress. Fisher's r-to-z transformation revealed no significant differences between control and stress groups with correlation coefficients. These findings are the first to show that chronic stress impairs both response inhibition and working memory, two behaviors that have never been directly compared within the same animals after chronic stress, using FMI, an appetitive task, and RAWM, a nonappetitive task.
Methods for microelectrode-guided posteroventral pallidotomy (1996)

Methods for localizing the posteroventral globus pallidus intermus are described. The authors' techniques include the use of microelectrodes to record single-unit activity and to microstimulate in human pallidum and its surrounding structures. This technique allows a precise determination of the locations of characteristic cell types in sequential trajectories through the external and internal segments of the pallidum. The location of the optic tract can be determined from microstimulation-evoked visual sensations and recordings of flash-evoked potentials. In addition, microstimulation-evoked motor and sensory responses allow the internal capsule to be identified. The data collected using this technique are an important adjunct to selecting optimum sites to place electrocoagulation lesions for stereotactic posteroventral pallidotomy for refractory Parkinson's disease.

Robust hybrid thin films that incorporate lamellar phospholipid bilayer assemblies and transmembrane proteins (2006)

This study describes facile methods based on sol-gel processing for the formation of robust thin films that incorporate phospholipid bilayer membranes and transmembrane proteins as multilamellar assemblies in cross-linked silica matrices. Transmission electron microscopy and x-ray diffraction were used to examine the lamellar structure of the hybrid thin films containing1, 2-dioleyl-sn-glycero-3-phospoethanolamine (DOPE), an unsaturated lipid, and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC), a saturated lipid. While the d spacing measured for DOPE containing films varied (from 35 to 48 A) depending on the amount of DOPE added to the coating solution (10-1 wt %), similar changes were not observed for the films containing saturated lipid, DMPC (d spacing approximately 43 A). Addition of purple membrane containing bacteriorhodopsin to the DOPE/silica coating solution led to the formation of multilamellar vesicle-like structures within the thin films. Mild sonication of these solutions containing the purple membrane prior to coating led to the formation thin films with planar multilamellar structures that exhibit uniform d spacing. The study further investigates the effects of incorporation of gramicidin and sonication on the structure of hybrid films and speculates on the eventual application of thin films prepared in this manner.
Use of Trifluoromethanesulfonic Acid in Fischer Glycosylations (1988)

Abstract The Fischer glycosylation1 is one of the standard reactions in carbohydrate chemistry, in which a reducing sugar is reacted under acid catalysis with a simple alcohol to give a glycoside. Hydrochloric acid is the classical catalyst, but other proton, Lewis acid, or acid form ion echange resins have also been used. Now, the use of trifluoromethanesulfonic acid (triflic acid) as a catalyst is communicated.
Synthesis of Racemates and (+)-Enantiomers ofγ-Caprolactone,γ-Dodecanolactone andδ-Hexadecanolactone, Lactonic Sex Pheromones of the Dermestid Beetle, Rove Beetle and Oriental Hornet (1983)

A simple method based on regioselective two-step alkylation of easily-available diethyl 3-oxoglutarate (2) is described for the synthesis of racemates of the lactonic pheromones, la, lb, and 1c. Their (+)-enantiomers were also synthesized by means of microbiological reduction of the intermediary keto acids.
