Genetic variants of the human obesity (OB) gene: association with body mass index in young women, psychiatric symptoms, and interaction with the dopamine D2 receptor (DRD2) gene. (1996)

To examine the possible role of genetic variants of the OB gene in obesity we examined alleles of a dinucleotide repeat polymorphism, D7S1875, close to the gene, in a group of adult, non-Hispanic Caucasians. There was a significant correlation with body mass index (BMI) at age 26-30 years for males and females combined (P = 0.04) and females only (P = 0.028). Because of the frequent association between obesity and psychiatric symptoms all subjects were screened with the Symptom List 90 (SCL-90). There was a significant increase in scores for anxiety (P = 0.0005), depression (P = 0.003), and other behaviors for subjects homozygous for the OB1875 < 208-bp alleles. Analysis of covariance indicated that this was directly related to the OB alleles and not secondary to the presence of obesity. There was a significant association between the BMI at ages 16 to 40 and homozygosity for the OB1875 < 208-bp alleles and/or the presence of the DRD2 Taq A1 allele for males and females combined (P = 0.002 to 0.005), and for females alone (P = 0.0017 to 0.0005). For females alone these two genes accounted for up to 22.8% of the variance of the BMI. These results are consistent with the polygenic inheritance of obesity, the greater involvement of genetic factors in women and younger individuals, and suggest that variants of the OB gene are causally involved not only in human obesity but its associated behavioral disorders.
Robust Recall and Long-Term Memory T-Cell Responses Induced by Prime-Boost Regimens with Heterologous Live Viral Vectors Expressing Human Immunodeficiency Virus Type 1 Gag and Env Proteins (2002)

We investigated long-term memory and recall cellular immune responses to human immunodeficiency virus type 1 (HIV-1) Env and Gag proteins elicited by recombinant vesicular stomatitis viruses (VSVs) expressing Env and Gag. More than 7 months after a single vaccination with VSV-Env, approximately 6% of CD8(+) splenocytes stained with major histocompatibility complex class I tetramers containing the Env p18-I10 immunodominant peptide and showed a memory phenotype (CD44(Hi)). The level of tetramer-positive cells in memory was about 14% of the peak primary response. Recall responses elicited in these mice 5 days after boosting with a heterologous recombinant vaccinia virus expressing HIV-1 Env showed that 40 to 45% of CD8(+) splenocytes were tetramer positive and activated (CD62L(Lo)), and these cells produced gamma interferon after stimulation with Env peptide, indicating that they were functional. Five months after the boost, the long-term memory cell population (tetramer positive, CD44(Hi)) constituted 30% of the CD8(+) splenocytes. Recall responses to HIV-1 Gag were examined in mice primed with VSV recombinants expressing HIV-1 Gag protein and boosted with a vaccinia virus recombinant expressing Gag. Using this protocol, we found that approximately 40% of CD8(+) splenocytes were activated (CD62L(Lo)) and specific for a Gag immunodominant peptide (tetramer positive). The high-level Gag recall response elicited by the vaccinia virus-Gag was greater than that obtained by boosting with a VSV-Gag vector with a different VSV glycoprotein. The corresponding levels of CD44(Hi) memory cells were also higher long after boosting with vaccinia virus-Gag than after boosting with a glycoprotein exchange VSV-Gag. Our results show that VSV vectors elicit high-level memory CTL responses and that these can be amplified as much as six- to sevenfold using a heterologous boosting vector.
Uniaxial Extension and Order Development in Flexible Chain Polymers (1995)

Abstract It is well known that the highest elastic moduli reported for linear poly-mers are generally much smaller than their theoretical values. This has been shown particularly by Nakamae and coworkers [1]. For a range of poly-mers they have summarized their crystal moduli determined by x-ray dif-fraction as measured in the stiffest direction, parallel to the polymer chain axis. These values on crystals approximate the ultimate polymer moduli; they therefore may be compared with the much lower presently reported values for the conventional structure of these polymers (Fig. 1). This figure shows that most polymers, including those with rigid backbone chains, have tensile moduli far below those of their crystalline lattice in the chain direction. The exceptions are specially drawn ultrahigh molecular weight polyethylene (UHMW PE), which in PE parlance is generally considered to mean molecular weight above one million, and for isotactic polypropyl-ene that also has been drawn to tensile moduli that approach the value from theory.
Arabidopsis PAD3, a Gene Required for Camalexin Biosynthesis, Encodes a Putative Cytochrome P450 Monooxygenase (1999)

Phytoalexins are low molecular weight antimicrobial compounds that are synthesized in response to pathogen attack. The phytoalexin camalexin, an indole derivative, is produced by Arabidopsis in response to infection with the bacterial pathogen Pseudomonas syringae. The phytoalexin deficient 3 (pad3) mutation, which causes a defect in camalexin production, has no effect on resistance to P. syringae but compromises resistance to the fungal pathogen Alternaria brassicicola. We have now isolated PAD3 by map-based cloning. The predicted PAD3 protein appears to be a cytochrome P450 monooxygenase, similar to those from maize that catalyze synthesis of the indole-derived secondary metabolite 2,4-dihydroxy-1, 4-benzoxazin-3-one. The expression of PAD3 is tightly correlated with camalexin synthesis and is regulated by PAD4 and PAD1. On the basis of these findings, we conclude that PAD3 almost certainly encodes an enzyme required for camalexin biosynthesis. Moreover, these results strongly support the idea that camalexin does not play a major role in plant resistance to P. syringae infection, although it is involved in resistance to a fungal pathogen.
Lipoprotein lipase in atherosclerosis: its presence in smooth muscle cells and absence from macrophages (1987)

The localization of lipoprotein lipase (LPL) in human atherosclerotic lesions was studied with immunocytochemical techniques. In the fibrous cap and surrounding intima of the plaque, where the smooth muscle cell is the dominating cell type, a high number of cells reacted with anti-LPL. A much lower number of stained cells was seen in the central lipid core region where the macrophages dominate. Further characterization of the LPL-containing cells in tissue sections showed that most of them were smooth muscle cells. Only a minor fraction of the macrophages in the plaque contained the enzyme. The results were confirmed on isolated cells from atherosclerotic tissue. Lipoprotein lipase was also detected in smooth muscle cells of non-atherosclerotic arteries. These findings suggest that the smooth muscle cells are the major source of LPL in the vascular wall. However, the enzyme was not present in some of the smooth muscle cells in the atherosclerotic lesion. This may imply that LPL synthesis is down-regulated in the atherosclerotic plaque.
Cloning and Sequencing of a Unique Antigen MPT70 from Mycobacterium tuberculosis H37Rv and Expression in BCG Using E. coli‐Mycobacteria Shuttle Vector (1995)

MPB70 is known to be an immunogenic mycobacterial protein secreted in large amounts from Mycobacterium bovis BCG (BCG) Tokyo. The analogous gene for MPT70 was cloned from Mycobacterium tuberculosis H37Rv which produces this protein in only a small amount. The gene encoding 193 amino acid residues including 30 amino acids for the signal peptide, the promoter-like sequence, and the ribosome-binding site, was completely identical to that of BCG Tokyo. Computer analysis revealed that the carboxy-terminal half of MPT70 was homologous to amino acid sequences of fasciclin I, osteoblast-specific factor 2 (OSF-2), and human transforming growth factor-beta induced gene product (beta IG-H3). Escherichia coli (E. coli) -mycobacteria shuttle vectors containing mpt70 or mpb70 genes 0.7kbp upstream of the 5' end of them were able to be expressed in BCG Pasteur which is a MPB70 low-producer, but the extent of the expression was not that of a high-producer.
Total Inhibin is a Potential Serum Marker for Epithelial Ovarian Cancer (2007)

Inhibins A and B are glycoproteins released by the human ovary. Levels of both forms become nondetectable, or nearly so, following menopause, but some ovarian tumors produce inhibin even in postmenopausal women. This controlled cross-sectional study evaluated a new immunoenzymatic assay for total inhibin, which detects both free inhibin α-subunit and inhibin dimers, as a tumor marker in women with epithelial ovarian cancers. Serum samples were taken from 4 groups of postmenopausal women: 89 with stage II–III epithelial ovarian cancers; 25 with benign epithelial ovarian tumors; 10 with cancer of the breast, colon, or stomach; and 95 normal control subjects. The epithelial ovarian cancers included 40 serous, 17 mucinous, 10 endometrioid, and 22 clear-cell adenocarcinomatous tumors. In addition to total inhibin, the samples were analyzed by enzyme-immunoassay for cancer antigen 125 (CA-125). The median serum total inhibin in women with epithelial ovarian cancer was 189 pg/mL, significantly higher than in all other groups. Levels were highest in patients having serous or mucinous tumors. Levels of CA-125 were significantly higher in women with epithelial ovarian cancers than in control subjects. Assay results were consistently improved by combining total inhibin and CA-125 levels. Compared to using a single marker, the rate of detection of clear-cell adenocarcinomas increased from 59%–68% to 96%. At 95% specificity, the total inhibin assay detected 93% of serous tumors and 94% of mucinous tumors. Combining both assays, again at 95% specificity, all serous and mucinous tumors were detected, and the overall sensitivity for epithelial ovarian cancers was 99%. Total inhibin levels declined significantly after serous or mucinous cancers were treated surgically. In 4 women with mucinous epithelial ovarian cancers who were followed up, total inhibin levels increased when disease recurred and decreased significantly after surgical treatment. The immunoenzymatic assay for total serum inhibin is a sensitive and specific marker of epithelial ovarian cancers in postmenopausal women. Optimal results are obtained by combining inhibin levels with those of CA-125. In addition to its diagnostic role, monitoring serum inhibin levels may be a useful means of detecting recurrent disease in treated patients.
Soma-germline asymmetry in the distributions of embryonic RNAs in Caenorhabditis elegans (1994)

Early embryogenesis in Caenorhabditis elegans is characterized by a series of unequal cleavages that mark the stepwise separation of somatic and germ lineages. We have developed an in situ hybridization protocol to examine the localization of specific maternal and embryonically transcribed messenger RNAs during these early cleavages. We detected three classes of maternal RNAs: RNAs that are maintained in all cells, RNAs that are maintained in germline cells but are lost from somatic cells, and a population of RNAs that are associated with the germline-specific P granules. We observed embryonically transcribed RNAs in somatic cells as early as the 4-cell stage. These transcripts were not detected in germline cells. These observations suggest that mechanisms which distinguish between soma and germline cause asymmetries in mRNA stability and transcription within the first few cleavages of C. elegans embryogenesis.
Internal tandem duplication of FLT3 (FLT3/ITD) induces increased ROS production, DNA damage, and misrepair: implications for poor prognosis in AML (2008)

Activating mutations of the FMS-like tyrosine kinase-3 (FLT3) receptor occur in approximately 30% of acute myeloid leukemia (AML) patients and, at least for internal tandem duplication (ITD) mutations, are associated with poor prognosis. FLT3 mutations trigger downstream signaling pathways including RAS-MAP/AKT kinases and signal transducer and activator of transcription-5 (STAT5). We find that FLT3/ITD mutations start a cycle of genomic instability whereby increased reactive oxygen species (ROS) production leads to increased DNA double-strand breaks (DSBs) and repair errors that may explain aggressive AML in FLT3/ITD patients. Cell lines transfected with FLT3/ITD and FLT3/ITD-positive AML cell lines and primary cells demonstrate increased ROS. Increased ROS levels appear to be produced via STAT5 signaling and activation of RAC1, an essential component of ROS-producing NADPH oxidases. A direct association of RAC1-GTP binding to phosphorylated STAT5 (pSTAT5) provides a possible mechanism for ROS generation. A FLT3 inhibitor blocked increased ROS in FLT3/ITD cells resulting in decreased DSB and increased repair efficiency and fidelity. Our study suggests that the aggressiveness of the disease and poor prognosis of AML patients with FLT3/ITD mutations could be the result of increased genomic instability that is driven by higher endogenous ROS, increased DNA damage, and decreased end-joining fidelity.
Etiology of acute pharyngitis in children: is antibiotic therapy needed? (2003)

Acute pharyngitis is a common upper respiratory tract disease in children. The aim of this study is to find the associated microorganisms and determinate whether antibiotics is needed. This study included a total of 416 children with a diagnosis of acute pharyngitis who were treated in an outpatient clinic In Taipei. Throat swabs for viral and bacterial cultures were taken. Antibiotics were prescribed when bacterial pharyngitis was suspected on the initial visit. The prescription was adjusted according to the results of bacterial culture and clinical manifestations on the second visit 3 to 4 days later. The mean age of the patients was 52.9 +/- 36.9 months. A total of 297 potential pathogens were isolated in 242 patients. Viruses were isolated in 123 (29.6%) patients. Bacteria were isolated in 73 (17.5%) patients, whereas group A streptococci were isolated in only 7 (1.7%) patients. Viruses mixed with bacteria were found in 46 (11.1%) patients. The mean age of patients with viral infections was lower than those with bacterial infections (47.5 +/- 30.4 vs 62.4 +/- 43.7 months, p = 0.01). There was a longer duration of fever in patients older than 2 years with viral isolates (p < 0.01). Antibiotics were prescribed for acute pharyngitis on the first visit in 43 (10.3%) patients, and on the second visit in 19 (4.6%) patients. In children with viral infection, mixed isolates, or no growth, there was significantly less prescription of antibiotics on the second visit. Given the low isolation rate of significant bacterial pathogens, routine throat cultures and antibiotics are not indicated in children with acute pharyngitis.
Ocimum basilicum: Antibacterial activity and association study with antibiotics against bacteria of clinical importance (2015)

Ocimum basilicum essential oil associated with existing standard antibiotics may increase their antibacterial activity, resulting in a synergistic activity against bacterial strains of clinical importance. The antibacterial activity of O. basilicum essential oil may be associated with linalool.
La critique littéraire féministe : une nouvelle lecture du roman féminin (1986)

Cet essai est une évaluation de la critique féministe telle qu'elle s'est développée aux Etats-Unis depuis une dizaine d'années. Une importance particulière est accordée à la « gynocritique » qui s'attache à la production du texte. Les principaux courants sont examinés qui visent à élucider le problème de la « différence » de l'écriture féminine, à reconnaître la présence d'une tradition littéraire féminine, revoir et réhabiliter des œuvres de fiction féminine. Enfin, on voit que cette critique féministe se veut prescriptive : informer et former le jugement des critiques comme des écrivains.
Comparing and Combining Measurement-Based and Driven-Dissipative Entanglement Stabilization (2016)

We demonstrate and contrast two approaches to the stabilization of qubit entanglement by feedback. Our demonstration is built on a feedback platform consisting of two superconducting qubits coupled to a cavity, which are measured by a nearly quantum-limited measurement chain and controlled by high-speed classical logic circuits. This platform is used to stabilize entanglement by two nominally distinct schemes: a "passive" reservoir engineering method and an "active" correction based on conditional parity measurements. In view of the instrumental roles that these two feedback paradigms play in quantum error correction and quantum control, we directly compare them on the same experimental setup. Furthermore, we show that a second layer of feedback can be added to each of these schemes, which heralds the presence of a high-fidelity entangled state in real time. This "nested" feedback brings about a marked entanglement fidelity improvement without sacrificing success probability.
Furanose-pyranose isomerization of reduced pyrimidine and cyclic urea ribosides (1986)

Tetrahydrouridine (THU, 2) and other fully reduced cyclic urea ribofuranosyl nucleosides undergo a rapid, acid-catalyzed isomerization to their more stable ribopyranosyl form. This isomerization is characterized by a change in spectral properties and by a greater than 10-fold decrease in potency for those nucleosides that act as potent inhibitors of cytidine deaminase in their ribofuranose form. 1-(beta-D-Ribopyranosyl)hexahydropyrimidin-2-one (7) was synthesized and used in conjunction with its furanose isomer 6 as a model compound for more extensive 1H and 13C NMR, mass spectral, and kinetic studies of this isomerization. The 0.4 delta upfield shift and 4-Hz increase in the J1',2' coupling constant for the pyranose anomeric proton in the 1H NMR spectrum is indicative of a pyranose beta-CI conformation in which the aglycon and C-2' and C-4' hydroxyls are equatorial. The mass spectra of trimethylsilylated pyranose nucleosides also show a characteristic large shift in the m/z 204-217 abundance and the appearance of two new rearrangement ions at M-133 and M-206. For furanose 6 the rate of isomerization is pH and temperature dependent with pyranose 7 predominating by a factor of 6-9 equilibrium. At pH 1 and 37 degrees C, furanose 6 has an initial half-life of less than 12 min. Accordingly, this isomerization may explain the observed lack of enhanced ara-C levels in studies evaluating the oral administration of an ara-C and THU combination to species with an acidic stomach content.
Association analysis of cytokine polymorphisms and plasma level in Northern Chinese Han patients with paroxysmal nocturnal hemoglobinuria. (2012)

Expression levels of the TNF-a, TGF-b, and IFN-g cytokines play an important role in PNH. The GC and CC genotypes, as well as the C allele of the IL-6 gene may protect the Han people of Northern China against PNH. Additionally, the TC/GG genotype of the TGF-b gene may be the protective allele. In contrast, the TA genotype and the T allele for the IFN-g gene, as well as the C allele of TGF-b may be susceptible to PNH. However, SNPs in the TNF-a and IL-10 genes did not correlate with PNH development. Alternatively, the increased plasma concentrations of TNF-a, TGF-b, and IFN-g in PNH patients may also be related to PNH development.
Characterization of theN-Acetylglucosaminyltransferase Activity Involved in the Biosynthesis of the Staphylococcus epidermidisPolysaccharide Intercellular Adhesin (1998)

The polysaccharide intercellular adhesin (PIA) is an important factor in the colonization of medical devices by Staphylococcus epidermidis. The genes encoding PIA production are organized in the icaADBC (intercellular adhesion) operon. To study the function of the individual genes, we have established an in vitro assay with UDP-N-acetylglucosamine, the substrate for PIA biosynthesis, and analyzed the products by thin-layer chromatography and mass spectrometry. IcaA alone exhibited a low N-acetylglucosaminyltransferase activity and represents the catalytic enzyme. Coexpression of icaA with icaD led to a significant increase in activity. The newly identified icaD gene is located between icaA and icaB and overlaps both genes. N-Acetylglucosamine oligomers produced by IcaAD reached a maximal length of 20 residues. Only when icaA and icaD were expressed together with icaC were oligomer chains that react with PIA-specific antiserum synthesized. IcaA and IcaD are located in the cytoplasmic membrane, and IcaC also has all the structural features of an integral membrane protein. These results indicate a close interaction between IcaA, IcaD, and IcaC. Tunicamycin and bacitracin did not affect the in vitro synthesis of PIA intermediates or the complete PIA biosynthesis in vivo, suggesting that a undecaprenyl phosphate carrier is not involved. IcaAD represents a novel protein combination among beta-glycosyltransferases.
Methods in clinical hemorheology: The continuous measurement of arterial blood density and blood sound speed in man (1990)

Both blood density and sound speed are closely related to total protein concentration in blood and, as a consequence, to rheologically important parameters of blood. Two methods that permit continuous measurement of these properties, the mechanical oscillator technique and the new ultrasonic technique, were used for measuring blood protein concentration over a continuous period of time in a group of hemodialysis patients and in volunteers. It was seen that the concentration of the components of blood varies considerably. This variability is related to transport phenomena within as well as to the flow of masses across the cardiovascular compartment. From the continuous measurement of concentrations during hemodialysis treatment, relative changes in blood volume can be recorded in order to control the fluid balance of the patient. Rapid fluctuations at the macroscopic scale with periods of 5 to 30 seconds are due to heterogeneities at the microscopic scale and to the particular rheological behaviour of the red blood cells at the level of the capillaries and the small blood vessels. The amplitude of rapid oscillations increased up to 1.2% in terms of hematocrit values when there was rhythmic, spontaneous breathing at various frequencies. The measurement of concentrations at an accessible measuring site may be used to investigate the rheology of blood in the human microvasculature.
Identification of Novel Selective Lysine‐Specific Demethylase 1 (LSD1) Inhibitors Using a Pharmacophore‐Based Virtual Screening Combined with Docking (2014)

Lysine-specific demethylase 1 (LSD1) plays an important role in regulating the lysine methylation at residues K4 and K9 on histone H3. High levels of LSD1 expression have been observed in several malignant tumors. In this study, we presented a pharmacophore-based virtual screening of a moderate database of 171 143 small molecules. A pharmacophore of LSD1 inhibitors was constructed for the first time and then used to screen the compound library combined with validated molecular docking tools followed by biochemical assays, led to the identification of 9 novel LSD1 inhibitors, showing their IC50 values in a range of 2.41-101 μm. Furthermore, compound XZ09 exhibited less inhibition against the homologous monoamine oxidase A (MAO-A) and B (MAO-B) displaying its moderate selectivity. Our study provides an effective virtual screening method to identify new LSD1 inhibitors and XZ09 represents a potent and selective lead compound to deserve further optimization for the treatment of LSD1 overexpressing cancers.
