Sexual dysfunction among middle aged women in the community (1988)

In a community survey of women aged 35-59 sexual functioning was studied in the 436 women with partners. One third of these women had operationally defined sexual dysfunction: impaired sexual interest was identified in 17% of women (68/406), vaginal dryness in 17% (73/434), infrequency of orgasm in 16% (60/379), and dyspareunia in 8% (30/379). Sexual dysfunctions were statistically significantly associated with increasing age and also with psychiatric disorder, neuroticism, and marital disharmony. One in 10 women regarded themselves as having a sexual problem. These women were no older than women with sexual dysfunction who did not regard themselves as having a sexual problem. Nevertheless, they differed from the rest of the sample in having more psychiatric disorder, neuroticism, marital disharmony, and (in women still menstruating) psychological symptoms of the premenstrual syndrome. In the whole sample 16 women (4%) said that they would like help for a sexual problem. The prevalence of sexual dysfunction in this series of women suggests that general practitioners should increase their alertness to the problem in their patients.
Immunotherapy with partially purified and standardized tree pollen extracts. IV. Results from long‐term (6‐year) follow‐up (1997)

The long‐term effect of tree pollen extract immunotherapy was investigated 6 years after termination of the treatment. Subjective symptom evaluation of 36 patients 6 years after a 3‐year period of immunotherapy showed that rhinitis and asthma symptoms remained at the improved level reached just after termination of the treatment. Some 86% of the rhinitis patients and 68% of the asthma patients maintained improvement. None of the rhinitis patients developed asthma in the study period. Skin prick tests reflected the outcome of the subjective symptom assessment. The skin sensitivity of the patients decreased significantly during immunotherapy, and the skin reactions 6 years after specific immunotherapy were still significantly lower than the pretreatment levels. Total IgE and birch‐specific IgE levels were constant throughout the study period, and both the affinity and epitope specificity of the IgE antibodies of the patients were the same before, during, and 6 years after treatment. In conclusion, specific immunotherapy reduces symptoms in patients suffering from rhinitis and asthma, and the effect is maintained 6 years after termination of the treatment. Specific immunotherapy seems to prevent long‐term development of asthma in rhinitis patients. IgE measurements do not reflect the overall status of the patients.

A Novel Synthetic Inhibitor of CDC25 Phosphatases (2004)

CDC25 dual-specificity phosphatases are essential regulators that dephosphorylate and activate cyclin-dependent kinase/cyclin complexes at key transitions of the cell cycle. CDC25 activity is currently considered to be an interesting target for the development of new antiproliferative agents. Here we report the identification of a new CDC25 inhibitor and the characterization of its effects at the molecular and cellular levels, and in animal models. BN82002 inhibits the phosphatase activity of recombinant human CDC25A, B, and C in vitro. It impairs the proliferation of tumoral cell lines and increases cyclin-dependent kinase 1 inhibitory tyrosine phosphorylation. In synchronized HeLa cells, BN82002 delays cell cycle progression at G1-S, in S phase and at the G2-M transition. In contrast, BN82002 arrests U2OS cell cycle mostly in the G1 phase. Selectivity of this inhibitor is demonstrated: (a) by the reversion of the mitotic-inducing effect observed in HeLa cells upon CDC25B overexpression; and (b) by the partial reversion of cell cycle arrest in U2OS expressing CDC25. We also show that BN82002 reduces growth rate of human tumor xenografts in athymic nude mice. BN82002 is a original CDC25 inhibitor that is active both in cell and animal models. This greatly reinforces the interest in CDC25 as an anticancer target.
Chronic interstitial infusion of protein to primate brain: determination of drug distribution and clearance with singlephoton emission computerized tomography imaging (1997)

High-flow interstitial infusion into the brain, which uses bulk fluid flow to achieve a relatively homogeneous drug distribution in the extracellular space of the brain, has the potential to perfuse large volumes of brain. The authors report reproducible long-term delivery of 111In-diethylenetriamine pentaacetic acid-apotransferrin (111In-DTPA-Tf) (molecular mass 81 kD) to Macaca mulatta brain and monitoring with single-photon emission computerized tomography (SPECT). The 111In-DTPA-Tf was infused at 1.9 microl/minute over 87 hours into the frontal portion of the centrum semiovale using a telemetry-controlled, fully implanted pump. On Days 1, 3, 4, 8, 11, and 15 after beginning the infusion, planar and SPECT scans of 111In-DTPA-Tf were obtained. Spread of protein in the brain ranged from 2 to 3 cm and infusion volumes ranged from 3.9 to 6.7 cm3. Perfusion of over one-third of the white matter of the infused hemisphere was achieved. From brain SPECT images of (99m)Tc-hexamethylpropyleneamine oxime, which was administered intravenously before each 111In scan, the authors also found that blood perfusion in the infused region was reduced by less than 5% relative to corresponding noninfused regions. Histological examination at 30 days revealed only mild gliosis limited to the area immediately surrounding the needle tract. These findings indicate that long-term interstitial brain infusion is effective for the delivery of drugs on a multicentimeter scale in the primate brain. The results also indicate that it should be possible to perfuse targeted regions of the brain for extended intervals to investigate the potential utility of neurotrophic factors, antitumor agents, and other materials for the treatment of central nervous system disorders.
Antimicrobial resistance among gram-negative organisms in the intensive care unit (2003)

Antibiotic resistance continues to rise among hospital-acquired gram-negative pathogens. Optimal management of these infections requires knowledge of local epidemiology and practices to control their spread.
Multi-polymer microstereolithography for hybrid opto-MEMS (2002)

We have developed a novel microstereolithography method for producing a hybrid structure using multiple photocurable polymers. This method, termed the Multi-polymer IH process, has the potential to provide us with various functional microdevices, such as actuators, sensors and optical devices. The microdevices are produced by combining the diverse properties of different photocurable polymers. To verify the basic performance of our process, several optical waveguides were made with two kinds of photocurable polymers having different refractive indexes. By combining the optical, electrical and mechanical properties of photocurable polymers, this process should advance Polymer MEMS technology and make a substantial contribution to microoptics and microchemical devices for BioMEMS.
Structures and Activity of Cellulase Inhibitors Enzymatically Synthesized from Cellooligosaccharides and 1-Deoxynojirimycin (1996)

Cellulase inhibitors were synthesized from cellooligosaccharides and 1-deoxynojirimycin (DNJ) by transglycosylation, using a commercial cellulase. The structures of these cellulase inhibitors were proved to be 4-O-beta-cellobiosyl-DNJ, 4-O-beta-D-glucopyranosyl-DNJ and 6-O-beta-cellobiosyl-DNJ by the results of 13C- and 1H-NMR analyses. The inhibitory activity of each inhibitor was investigated against several carboxymethylcellulases.
Role of prostacyclin (epoprostenol) as anticoagulant in continuous renal replacement therapies: efficacy, security and cost analysis (2006)

Epoprostenol may be safely used to prevent clotting of the extracorporeal circuits, either alone in patients with thrombocytopenia and/or increased risk of bleeding, or in combination with heparin in states of hypercoagulability.
Sonochemically produced fluorocarbon microspheres: A new class of magnetic resonance imaging agent (1996)

With the intent of increasing the signal-to-noise ratio (SNR) of fluorine magnetic resonance imaging and enabling new applications, we have developed a novel class of agents based on protein encapsulation of fluorocarbons. Microspheres formed by high-intensity ultrasound have a gaussian size distribution with an average diameter of 2.5 microns. As with conventional emulsions, these microspheres target the reticuloendothelial system. However, our sonochemically produced microspheres, because of a high encapsulation efficiency, show increases in the SNR of up to 300% compared to commercially available emulsions. We also demonstrate an increase in the circulation lifetime of the microspheres with the bloodstream by more than 30-fold with a chemical modification of the outer surface of the microsphere. Finally, by encapsulating mixtures of fluorocarbons that undergo solid/liquid phase transitions, we can map temperature in the reticuloendothelial system, with signal changes of approximately 20-fold over a 5 degrees C range.
Efficacy and safety of immunoglobulin apheresis. (1997)

Extracorporeal procedures such as plasmapheresis or protein a apheresis have been applied successfully to remove autoantibodies in the treatment of severe forms of various autoimmune diseases. A newly developed immunoapheresis technique that uses columns containing polyclonal anti human immunoglobulin (Ig) antibodies was investigated in four patients with idiopathic thrombocytopenic purpura (ITP). A series of two to four treatments were performed, and the period between the two series was dependent on the actual thrombocyte count. A total of 38 treatments was carried out. During the first apheresis, IgG declined to a mean of 52.7% of the initial concentration. The IgG subclasses one through four were decreased to the same extent. The IgA was lowered to 64.4%, and IgM was lowered to 66.7%. A series of four aphereses yielded a 75-80% decline of the different Ig species. A further decrease in Ig would have been possible, but was not aimed at in this study. All Ig fractions reincreased between the two series. In two patients, a rise in thrombocytes as a response to treatment was observed. Apart from three hypotensive reactions and one episode of hypocalcemia, no further side effects occurred in 38 treatments. The authors conclude that Ig apheresis with anti human Ig antibodies is an effective and safe form of treatment. Its effect on the clinical course of autoimmune diseases merits further investigation.
Delta-24-RGD in Combination With RAD001 Induces Enhanced Anti-glioma Effect via Autophagic Cell Death (2008)

Novel therapies are clearly needed for the treatment of gliomas, and strategies that involve combining oncolytic vectors with chemotherapy hold out significant hope for a more effective treatment of this malignancy. Whether chemotherapy acts directly on tumor cells by inducing cell arrest or cell death, or indirectly by blocking tumor angiogenesis, the resulting delay in tumor growth may provide the oncolytic virus with a wider window of opportunity to overcome the challenge imposed by the growth kinetics of the tumor. In this study we sought to determine whether the oncolytic adenovirus Delta-24-RGD, in combination with everolimus (RAD001), would result in an enhanced anti-glioma effect in vivo. Viability assays showed that Delta-24-RGD antitumoral activity is synergistically enhanced by combination with RAD001. Interestingly, combination treatment of Delta-24-RGD with RAD001 induced autophagy in vitro. We showed that Delta-24-RGD improved survival of tumor-bearing animals in a dose-dependent manner. A significant finding was that RAD001 enhanced the anti-glioma effect of Delta-24-RGD and resulted in the long-term survival of 80% of the experimental animals. Immunostaining of the treated tumors showed upregulation of Atg5, thereby indicating the therapeutic induction of autophagy. This is the first report showing that Delta-24-RGD plus RAD001 causes autophagic cell death, and dramatically increases long-term survival rates of glioma-bearing animals.
Regulatory T cells (PP-045) (2010)

Regulatory T cells (Treg) engage in the control for immune homeostasis. Foxp3 is the most critical for the function of those regulatory T cells. However it still remains to be elucidated that on the mechanism of transcriptional activation for Foxp3. Mice lacking NF-kB/RelA subunit are embryonic lethal due to apoptosis of liver cells induced by tumor necrosis factor (TNF). Mice lacking RelA and TNF are born with live livers. However those mice die within 3-4 weeks after birth. Histological feature is that there are a lot of lymphocytes infiltrating in livers and closely similar to autoimmune diseases. Administration of TNF/RelA deficient spleen cells into immune-deficient mice (Scid) induced autoimmunity. Expression of Foxp3 of spleen cells is defect from TNF/RelA deficient mice have no expression of Foxp3. With in vitro induction of regulatory T cells from CD4+/CD25spleen cells using TGF-beta, Foxp3+ cells did not appear from cells deficient of RelA. And CD4+/CD25+ cells deficient of RelA did not suppress CD4+/CD25-cells. However thymic cells in TNF/RelA deficient mice have the same expression of Foxp3 as wild type mice. Thus NF-kB/ RelA is the critical regulator for regulatory T cells, especially inducible Treg in spleen, not for natural Treg in thymus, through Foxp3 expression. And NF-kB/RelA subunit is the most essential for "executive Treg" in regulation of autoimmunity.
An Arabidopsis mutant showing reduced feedback inhibition of photosynthesis (1997)

Many plant genes are responsive to sugars but the mechanisms used by plants to sense sugars are unknown. A genetic approach has been used in Arabidopsis to identify genes involved in perception and transduction of sugar signals. For this purpose, an in vivo reporter system was established consisting of the light- and sugar-regulated plastocyanin promoter, fused to the luciferase coding sequence (PC-LUC construct). At the seedling stage, expression of the PC-LUC gene is repressed by sucrose, and a number of sucrose-uncoupled (sun) mutants were selected in which sucrose is unable to repress the activity of the PC promoter. Three mutants have been characterized in more detail. The sugar analog 2-deoxy-D-glucose (2DG) was used to repress whole plant photosynthesis, PC-LUC gene expression and total ribulose-1,5-bisphosphate activity. It was found that the sun6 mutation makes plants unresponsive to these 2DG-induced effects. Moreover, unlike wild-type plants, sun6 mutants are insensitive to elevated levels of glucose in the growth medium. These findings suggest that the SUN6 gene is active in a hexose-activated signal transduction pathway.
Restricted association of V and J-C gene segments for mouse lambda chains. (1984)

The frequencies of diverse rearrangements of variable (V)lambda to joining (J)lambda gene segments were examined by Southern blot hybridization in 30 murine B-cell lines, each producing an immunoglobulin lambda light chain of known subtype (lambda 1, lambda 2, or lambda 3). For 11 out of 12 lambda 1 chains, the rearrangement was V lambda 1----J lambda 1; for 9 out of 9 lambda 2 chains, it was V lambda 2----J lambda 2; and for 8 out of 9 lambda 3 chains, it was V lambda 1----J lambda 3. Similar results were obtained by considering the partial or complete sequences at the amino acid or cDNA level of 44 other lambda chains (24 previously described): for 43 of these chains the rearranged V-J gene segments were evidently V lambda 1-J lambda 1 for 28 lambda 1 chains, V lambda 2-J lambda 2 for 10 lambda 2 chains, and V lambda 1-J lambda 3 for 5 lambda 3 chains. Of the combined total of 74 chains there were 3 with unusual V lambda rearrangements, all involving the V lambda 2 gene segment: for 2 of these unusual chains, the encoding segments were V lambda 2-J lambda 1-C lambda 1 and for one they were V lambda 2-J lambda 3-C lambda 3. Thus, the results for all 74 lambda chains show that, in contrast to the apparently unrestricted V kappa----J kappa rearrangements for kappa chains, for each of the 3 murine lambda-chain subtypes V-J recombination is severely restricted: the V lambda gene segment expressed in lambda 1 and lambda 3 chains was nearly always V lambda 1 (95% and 93%, respectively), whereas in lambda 2 chains it was without exception V lambda 2 (19 out of 19 chains). Therefore V lambda-J lambda combinatorial variation is not a significant source of amino acid sequence diversity of lambda chains of inbred mice. If the order of the lambda gene segments is 5' V lambda 2-J lambda 2C lambda 2J lambda 4C lambda 4-V lambda 1-J lambda 3C lambda 3J lambda 1C lambda 1 3', as suggested previously and by the present findings, it appears that (i) when a V lambda gene segment rearranges in a developing B cell it ordinarily recombines with a J lambda gene segment in the nearest downstream (3') cluster of J lambda C lambda segments, and (ii) V lambda rearrangement to the upstream (5') cluster is very rare and possibly may not take place at all.
A mixed excitation LPC vocoder model for low bit rate speech coding (1995)

Traditional pitch-excited linear predictive coding (LPC) vocoders use a fully parametric model to efficiently encode the important information in human speech. These vocoders can produce intelligible speech at low data rates (800-2400 b/s), but they often sound synthetic and generate annoying artifacts such as buzzes, thumps, and tonal noises. These problems increase dramatically if acoustic background noise is present at the speech input. This paper presents a new mixed excitation LPC vocoder model that preserves the low bit rate of a fully parametric model but adds more free parameters to the excitation signal so that the synthesizer can mimic more characteristics of natural human speech. The new model also eliminates the traditional requirement for a binary voicing decision so that the vocoder performs well even in the presence of acoustic background noise. A 2400-b/s LPC vocoder based on this model has been developed and implemented in simulations and in a real-time system. Formal subjective testing of this coder confirms that it produces natural sounding speech even in a difficult noise environment. In fact, diagnostic acceptability measure (DAM) test scores show that the performance of the 2400-b/s mixed excitation LPC vocoder is close to that of the government standard 4800-b/s CELP coder.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Rat Embryonic Stem-Like (ES-Like) Cells Can Contribute to Extraembryonic Tissues In Vivo (2007)

Despite significant advances achieved through gene targeting in mouse embryonic stem (ES) cells, this technology is presently only available in mice. Because the rat is a species of undeniable importance to biomedical research, attempts at derivation of rat ES cell lines have been ongoing for many years; however, the putative rat ES cell lines that have been reported to date have not yet displayed the ability to contribute in vivo to developing tissues following embryo injection. In contrast to previous studies, we describe herein the successful derivation and characterization of rat ES-like cell lines that not only express markers of undifferentiated cells, alkaline phosphatase (AP) activity and stage-specific embryonic antigen-1 (SSEA-1) cell surface antigen, but also retain expression of Oct4 (also known as Pou5f1) a homeodomain transcription factor and molecular marker of pluripotent cells. Notably, these rat ES-like cells, when injected into blastocysts transferred to pseudopregnant females, can contribute to developing extraembryonic tissues. This report demonstrates for the first time that rat ES-like cells can be derived efficiently, can express a panel of pluripotent cell markers, can be genetically modified in vitro and cryopreserved, and importantly, are capable of contributing to extraembryonic tissues in vivo.
Semidominant Mutations in the Yeast Rad51 Protein and Their Relationships with the Srs2 Helicase (1996)

Suppressors of the methyl methanesulfonate sensitivity of Saccharomyces cerevisiae diploids lacking the Srs2 helicase turned out to contain semidominant mutations in Rad5l, a homolog of the bacterial RecA protein. The nature of these mutations was determined by direct sequencing. The 26 mutations characterized were single base substitutions leading to amino acid replacements at 18 different sites. The great majority of these sites (75%) are conserved in the family of RecA-like proteins, and 10 of them affect sites corresponding to amino acids in RecA that are probably directly involved in ATP reactions, binding, and/or hydrolysis. Six mutations are in domains thought to be involved in interaction between monomers; they may also affect ATP reactions. By themselves, all the alleles confer a rad5l null phenotype. When heterozygous, however, they are, to varying degrees, negative semidominant for radiation sensitivity; presumably the mutant proteins are coassembled with wild-type Rad51 and poison the resulting nucleofilaments or recombination complexes. This negative effect is partially suppressed by an SRS2 deletion, which supports the hypothesis that Srs2 reverses recombination structures that contain either mutated proteins or numerous DNA lesions.
