Regulation of HDAC9 Gene Expression by MEF2 Establishes a Negative-Feedback Loop in the Transcriptional Circuitry of Muscle Differentiation (2006)

Skeletal muscle development is controlled by the myocyte enhancer factor (MEF2) and myogenic basic helix-loop-helix (bHLH) families of transcription factors, which associate and synergistically activate muscle gene expression. Muscle differentiation is further reinforced by positive-feedback loops in which myogenic bHLH proteins activate their own expression and the expression of MEF2, while MEF2 stimulates expression of myogenic bHLH genes and the Mef2c gene. Here we describe a myogenic negative-feedback loop that consists of MEF2 proteins and the transcriptional repressor histone deacetylase 9 (HDAC9). We show that the HDAC9 gene is a direct transcriptional target of MEF2 in vitro and in vivo. HDAC9 can associate with MEF2 proteins and suppress their transcriptional activity. The transcriptional repressor HDAC9 thus forms a negative-feedback loop in the transcriptional circuitry of muscle differentiation.
Consensus guidelines for the use and interpretation of angiogenesis assays (2018)

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference.
Expression and putative role of 11 beta-hydroxysteroid dehydrogenase isozymes within the human eye. (2001)

These results suggest that the 11 beta-HSD1 isozyme may modulate steroid-regulated sodium transport across the NPE, thereby influencing IOP.
Right heart support during off-pump coronary artery bypass surgery--a multi-center study. (2002)

Heart displacement caused a significant hemodynamic deterioration that was stabilized with right heart support. The Enabler system is safe and effective in facilitating multi-vessel OPCAB surgery. However, there are still serious technical problems during cannula insertion that cause an unacceptable failure rate of device utilization.
High resolution three-dimensional flash LIDAR system using a polarization modulating Pockels cell and a micro-polarizer CCD camera (2016)

An innovative flash LIDAR (light detection and ranging) system with high spatial resolution and high range precision is proposed in this paper. The proposed system consists of a polarization modulating Pockels cell (PMPC) and a micro-polarizer CCD camera (MCCD). The Pockels cell changes its polarization state with respect to time after a laser pulse is emitted from the system. The polarization state of the laser-return pulse depends on the arrival time. The MCCD measures the intensity of the returning laser pulse to calculate the polarization state, which gives the range. A spatial resolution and range precision of 0.12 mrad and 5.2 mm at 16 m were obtained, respectively, in this experiment.
High-speed InGaP/GaAs HBTs with a strained In/sub x/Ga/sub 1-x/As base (1996)

A self-aligned InGaP/GaAs heterojunction bipolar transistor with a compositionally graded In/sub x/Ga/sub 1-x/As base has been demonstrated with f/sub T/=83 GHz and f/sub max/=197 GHz. To our knowledge, these results are the highest reported for both parameters in InGaP/GaAs HBT's. The graded base, which improves electron transport through the base, results in a DC current gain and a cutoff frequency which are 100% and 20% higher, respectively, than that achieved by an identical device with a nongraded base. The high f/sub max/ results from a heavily doped base, self-aligned base contacts, and a self-aligned collector etch. These results demonstrate the applicability of InGaP/GaAs HBT's in high-speed microwave applications.

Effects of continuous and pulsed microwave irradiation on distribution of heat in the gluteal region of minipigs. A comparative study (1989)

Eleven experiments were conducted on minipigs for the purpose of determining heat distribution in tissue exposed to therapeutic doses of microwaves. Temperatures were measured by means of coated thermocouples from the cutis, subcutis, musculature, and periost. Irradiation was applied to intensities of 10 W, 40 W and 60 W by means of a "Radarmed 12 S 251" circular emitter and to 60 W, 100 W and 140 W, using a trough emitter. Maximum temperature in superficial tissue layers was reached after five to ten minutes of microwave exposure. The temperature rise in the cutis and subcutis was steeper and at a higher rate than that in the muscles. Continuation of microwave irradiation did not cause any further rise in temperature, which was attributed to induction of hyperaemia. No difference regarding heat distribution was found to exist between pulsed and continuous irradiation at equal wattage.
Mouse models for BRAF-induced cancers (2007)

Oncogenic mutations in the BRAF gene are detected in approximately 7% of human cancer samples with a particularly high frequency of mutation in malignant melanomas. Over 40 different missense BRAF mutations have been found, but the vast majority (>90%) represent a single nucleotide change resulting in a valine-->glutamate mutation at residue 600 ((V600E)BRAF). In cells cultured in vitro, (V600E)BRAF is able to stimulate endogenous MEK [MAPK (mitogen-activated protein kinase)/ERK (extracellular-signal-regulated kinase) kinase] and ERK phosphorylation leading to an increase in cell proliferation, cell survival, transformation, tumorigenicity, invasion and vascular development. Many of these hallmarks of cancer can be reversed by treatment of cells with siRNA (small interfering RNA) to BRAF or by inhibiting MEK, indicating that BRAF and MEK are attractive therapeutic targets in cancer samples with BRAF mutations. In order to fully understand the role of oncogenic BRAF in cancer development in vivo as well as to test the in vivo efficacy of anti-BRAF or anti-MEK therapies, GEMMs (genetically engineered mouse models) have been generated in which expression of oncogenic BRaf is conditionally dependent on the Cre recombinase. The delivery/activation of the Cre recombinase can be regulated in both a temporal and spatial manner and therefore these mouse models can be used to recapitulate the somatic mutation of BRAF that occurs in different tissues in the development of human cancer. The data so far obtained following Cre-mediated activation in haemopoietic tissue and the lung indicate that (V600E)BRAF mutation can drive tumour initiation and that its primary effect is to induce high levels of cyclin D1-mediated cell proliferation. However, hallmarks of OIS (oncogene-induced senescence) are evident that restrain further development of the tumour.
Modafinil Decreases Hypersomnolence in the English Bulldog, a Natural Animal Model of Sleep-Disordered Breathing (1996)

The English bulldog is a natural model of sleep-disordered breathing (SDB). This condition is marked by 1) hypersomnolence and 2) disordered breathing episodes that are most frequent and severe during rapid eye movement (REM) sleep. Modafinil has been found to increase arousal levels in animals and decrease excessive daytime sleepiness in humans. Therefore, in this study we focused mainly on the effects of the drug on total sleep time and sleep latency and secondarily assessed its effect on REM SDB. Five English bulldogs were implanted with subcutaneous electroencephalographic/electrooculographic (EEG/EOG) electrodes and instrumented with respiratory oscillation belts to measure abdominal and rib cage movements and an ear oximeter to measure saturation. The dogs were studied for approximately 8 hours each subsequent day on two consecutive days. On the first day, they received the vehicle dimethyl sulfoxide (DMSO) i.v. as a control. On the following day they received 10 mg/kg body weight of modafinil i.v. dissolved in the DMSO vehicle. Our findings indicate that modafinil significantly alleviates hypersomnolence (p < 0.05) in the bulldog, as evidenced by dramatically decreased mean total sleep time (from a control value of 50.5% to 8.3% with the drug) and increased mean sleep latency (from a control value of 71.0 minutes to a value of 346.6 minutes with the drug). We obtained limited data on the effect of modafinil on SDB because the drug either greatly diminished or entirely eradicated REM sleep in all five dogs.
Molecular cloning of mouse epiregulin, a novel epidermal growth factor‐related protein, expressed in the early stage of development (1995)

A cDNA clone encoding a novel epidermal growth factor (EGF)-related growth regulator, epiregulin, was isolated from a cDNA library prepared from a mouse fibroblast-derived tumor cell line, NIH3T3/clone T7. The predicted amino acid sequence revealed that the purified epiregulin peptide of 46-amino acids was synthesized as an internal segment of a 162-amino acid putative transmembrane precursor. The structural organization was similar to that of TGF-alpha precursor among the members of the EGF family. Although epiregulin transcript was not detected in several adult normal tissues by Northern blot analysis, approximately 4.8-kb transcript was present in 7-day-old mouse embryo and then diminished to very low or undetectable levels. Our results suggest that epiregulin may play an important role in the regulation of epithelial cell growth during early development.

Molecular Vehicle Properties of the Broad Host Range Plasmid RK2 (1975)

The pladmid RK2 is stably maintained in a broad range of gram-negative bacteria. The RK2 DNA has a single Eco RI restriction site. The insertion of a DNA fragment into this site does not interfere with either plasmid maintenance or self-transmissibility. Because RK2 has a broad host range, it should be useful for the construction in vitro of hybrid plasmid molecules capable of being established by conjugal transfer or transformation into many genera of gram-negative organisms.
Circulatory and alpha‐adrenoceptor blocking effects of phentolamine. (1978)

1 Intravenously administered phentolamine provoked immediate decreases in diastolic blood pressure but increases in heart rate and cardiac output. 2 These immediate circulatory effects had largely disappeared twenty minutes after administration and at this time phentolamine did not inhibit increases in blood pressure which were provoked during hand immersion in ice‐cold water. 3 Log dose‐response curves of noradrenaline induced increases in systolic and diastolic pressure 20 min after intravenous phentolamine were shifted to the right in a parallel manner compared with the curves before phentolamine administration. 4 It was concluded that the immediate and short acting effects induced by phentolamine are due to a non‐specific vasodilator effect but in addition phentolamine causes a longer acting alpha‐ adrenoceptor blockade at vascular adrenoceptor sites. However, by producing both pre‐ and post‐synaptic alpha‐adrenoceptor blockade this may explain why this drug exerts only a weak antihypertensive effect.
Pooled Analysis of a Self-Sampling HPV DNA Test as a Cervical Cancer Primary Screening Method (2012)

The sensitivity of Self-HPV testing compared favorably with that of LBC and was superior to the sensitivity of VIA. Self-HPV testing may complement current screening programs by increasing population coverage in settings that do not have easy access to comprehensive cytology-based screening.

Topographical characterization of cone photoreceptors and the area centralis of the canine retina. (2008)

We have described the distribution of rods and cone subtypes within the canine retina and calculated a predictable location for the area centralis. These findings will facilitate the characterization and treatment of cone photoreceptor dystrophies in the dog.
Dissipative dispersion-managed solitons in mode-locked lasers (2009)

We extend the theory of dispersion-managed solitons to dissipative systems with a focus on mode-locked fiber lasers. Dissipative structures exist at high map strengths, leading to the generation of stable, short pulses with high energy. Two types of intramap pulse evolution are observed depending on the net cavity dispersion. These are characterized by a reduced model, and semianalytical solutions are obtained.
CNI-H0294, a Nuclear Importation Inhibitor of the Human Immunodeficiency Virus Type 1 Genome, Abrogates Virus Replication in Infected Activated Peripheral Blood Mononuclear Cells (1998)

Active nuclear importation of the human immunodeficiency virus (HIV) type 1 (HIV-1) preintegration complex (PIC) is required for the productive infection of nondividing cells, but it is believed to be dispensable for the infection of proliferating cells, such as activated T lymphocytes. To investigate this question, we exploited the properties of the small arylene bis (methyl ketone) compound CNI-H0294. We have previously shown that this compound associated with the HIV-1 matrix protein nuclear localization sequence and blocked binding of the HIV-1 PIC to yeast karyopherin alpha. CNI-H0294 abrogated nuclear importation of the HIV-1 genome in macrophages and effectively inhibited infection of nondividing cells. In this study we demonstrate that CNI-H0294 inhibits binding of the HIV-1 PIC to human karyopherin alpha and reduces nuclear importation of the viral genome in primary peripheral blood mononuclear cells (PBMCs). We also demonstrate that CNI-H0294 inhibits acute infection of PBMC cultures in vitro with a primary isolate of HIV-1 and reduces virus replication and virus load in cultures of endogenously infected PBMCs from seropositive individuals. Thus, as for infection of nondividing, terminally differentiated macrophages, HIV-1 uses active nuclear importation of the virus genome to infect activated CD4+ T cells. These results support nuclear importation as a novel target and CNI-H0294 and its derivatives as novel compounds for therapeutic intervention in HIV infection and AIDS.
Crystal Growth Inhibitors for the Prevention of l -Cystine Kidney Stones Through Molecular Design (2010)

Crystallization of L-cystine is a critical step in the pathogenesis of cystine kidney stones. Treatments for this disease are somewhat effective but often lead to adverse side effects. Real-time in situ atomic force microscopy (AFM) reveals that L-cystine dimethylester (L-CDME) and L-cystine methylester (L-CME) dramatically reduce the growth velocity of the six symmetry-equivalent {100} steps because of specific binding at the crystal surface, which frustrates the attachment of L-cystine molecules. L-CDME and L-CME produce l-cystine crystals with different habits that reveal distinct binding modes at the crystal surfaces. The AFM observations are mirrored by reduced crystal yield and crystal size in the presence of L-CDME and L-CME, collectively suggesting a new pathway to the prevention of L-cystine stones by rational design of crystal growth inhibitors.
Effect of Long-Term Monitoring of Glycosylated Hemoglobin Levels in Insulin-Dependent Diabetes Mellitus (1990)

Regular measurements of hemoglobin A1c lead to changes in diabetes treatment and improvement of metabolic control, indicated by a lowering of hemoglobin A1c values.
Cyclin-Dependent Kinase-Associated Protein Cks2 is Associated with Bladder Cancer Progression (2011)

In this observational retrospective study, expression of possible cancer-related genes was measured in patients with a pathological diagnosis of superficial bladder cancer. Further measurements were made in those who subsequently developed muscle-invasive cancer. Seven of the 45 patients with superficial bladder cancer progressed to muscle-invasive cancer. Expression of fatty acid binding protein 5 (FABP5), poly(A) binding protein cytoplasmic 1 (PABPC1), DEAD box polypeptide 5 (DDX5), splicing factor 3b subunit 1 (SF3B1), murine mammary tumour integration site 6 (EIF3S6), tropomyosin 2β (TPM2), transgelin (TAGLN) and cyclin-dependent kinase-associated protein (Cks2) genes was measured in bladder samples using real-time reverse transcription-polymerase chain reaction. FABP5, PABPC1, DDX5, SF3B1, EIF3S6 and Cks2 expression levels were significantly increased, and TPM2 and TAGLN were significantly decreased, in superficial bladder cancer compared with normal bladder tissue. In patients who developed muscle-invasive cancer, the Cks2 gene showed significantly increased expression after, compared with before, invasion. The Cks2 gene may have potential as a biomarker for predicting superficial bladder cancer progression to muscle-invasive cancer.
Pollinex®Quattro: a novel and well–tolerated, ultra short–course allergy vaccine (2006)

Pollinex Quattro is a novel, ultra short-course vaccine for treatment of seasonal allergic rhinitis from grass, tree or ragweed pollen allergy. Its unique formulation combines chemically modified allergens adsorbed onto a L-tyrosine depot to enhance tolerability with the novel adjuvant, monophosphoryl lipid A, to improve efficacy. Controlled clinical studies indicate that four preseasonal injections with grass or tree formulations significantly reduce rhinoconjunctivitis symptoms and medication use, as well as elevate allergen-specific immunoglobulin G and blunt elevation of immunoglobulin E upon allergen exposure. Postmarketing surveillance studies indicate similar clinical outcomes. In all cases, the allergy vaccine was well tolerated with minimal local reactions, while systemic reactions were rare and mild. Results from recent investigational trials with grass and ragweed formulations are consistent with previous efficacy and safety outcomes, and will be used toward product registration in North America.
Infrared ellipsometry investigation of SiOxNy thin films on silicon (1996)

The dielectric function ˜ε (˜ε = ε(1) + iε(2)) of silicon oxynitride films deposited on silicon wafers by dual ion-beam sputtering is determined by infrared ellipsometry between 580 and 5000 cm(-1). The phase-separation model is unable to reproduce the experimental data. The dependence of ˜ε on stoichiometry is analyzed with the microscopic Si-centered tetrahedron model. The random-bonding model with five SiO(4-j)N(j) (j = 0-4) tetrahedra gives a good description of the spectra, provided the dielectric function of the mixed tetrahedra is carefully chosen.
Small Molecule and Biologic Modulators of the Immune Response to Hepatitis C Virus (2006)

Hepatitis C virus represents a major global health problem, with approximately 3% of the world population infected. Immune-response modifiers represent the standard of care, given the lack of approved antiviral agents having direct activity against the viral proteins. Although in recent years, improvements in therapy have been attained by combined treatment with pegylated interferon and ribavirin, the discovery and development of next-generation small molecule and biologic agents is ongoing. Several of these newer therapeutics are focused on modulating Toll-like receptors, interferon-alpha signaling, and the pro-inflammatory cytokine balance. A comprehensive account of the lead compounds in development, the bioassays used for optimization of these immune response modifiers and their clinical status is presented.
The genetic data environment an expandable GUI for multiple sequence analysis (1994)

An X-Windows-based graphic user interface is presented which allows the seamless integration of numerous existing biomolecular programs into a single analysis environment. This environment is based on a core multiple sequence editor that is linked to external programs by a user-expandable menu system and is supported on Sun and DEC workstations. There is no limitation to the number of external functions that can be linked to the interface. The length and number of sequences that can be handled are limited only by the size of virtual memory present on the workstation. The sequence data itself is used as the reference point from which analysis is done, and scalable graphic views are supported. It is suggested that future software development utilizing this expandable, user-defined menu system and the I/O linkage of external programs will allow biologists to easily integrate expertise from disparate fields into a single environment.
Biochemical and Genetic Studies with Lysine + Methionine Mutants of Escherichia coli: Lipoic Acid and -Ketoglutarate Dehydrogenase-less Mutants (1968)

SUMMARY: A selection procedure was developed for the isolation of mutants of Escherichia coli which require lipoic acid, acetate+succinate, or lysine + methionine for aerobic growth with glucose. The properties of the mutants requiring lipoic acid (lip −) were compared with those of suc − mutants which lack α-ketoglutarate dehydrogenase and require succinate or lysine + methionine. Genetic analysis by conjugation with Hfr and F’ donors indicated that the genetic loci of some 36 independently isolated lip − mutants are confined to a small segment of the E. coli chromosome between the purE and suc sites. By using phage P1 no cotransduction of lip with suc, glt A or purE could be demonstrated, but suc, gltA and gal were cotransducible and the relative order of these sites was determined.
