Magnetic Susceptibility of the Cubic Sodium Tungsten Bronzes (1962)

The sodium tungsten bronzes (NaxWO3) in the cubic range 0.45&lt;x&lt;1.0 were found to have mass susceptibilities from 0.007×10—6 for x=0.49 to 0.053×10—6 for x=0.85. This feeble paramagnetism was found to be temperature independent from 70° to 300°K for three representative samples with x=0.49, 0.76, and 0.85. The susceptibility of WO3 was determined to be —0.060×10—6 emu/g and is also temperature independent. Satisfactory agreement between calculated and observed susceptibilities was obtained with a model which assumes that the bronzes consist of a dispersion of sodium ions in a WO3 lattice. The molar susceptibility, then, can be calculated from the equation χM=χ(WO3)+xχ(Na+)+χe. The term χe for the Pauli paramagnetism was obtained for two cases: (a) for nearly free electrons (m*=1.6m), and (b) for the density of states taken from the literature data on the low temperature heat capacity of the bronzes. Best quantitative agreement was obtained between the calculated and the observed susceptibilities for case b and indicates a more rapid increase in the density of states than simply E½.
Antibodies to Pneumolysin and Pneumococcal Capsular Polysaccharides in Middle Ear Fluid of Children with Acute Otitis Media (1995)

Antibodies to pneumococcal pneumolysin and capsular polysaccharides were measured by enzyme immunoassay in 169 acute phase middle ear fluid samples of 116 children with acute otitis media. Antibodies to pneumococcal pneumolysin were detected in 84% and to capsular polysaccharides in 50% of the MEF samples. The Ig class detected most often was IgA to both types of pneumococcal antigens, and it was present in MEF even with non-detectable levels of serum IgA of the same specificity. 59% of the MEF samples positive for IgA to pneumolysin were also positive for secretory component of the same specificity, and 53% of IgA to capsular polysaccharide pool (containing serotypes 6B, 14, 19F, and 23F), respectively. This suggests both leakage of specific IgA from serum to the middle ear and local production of it. In contrast, specific IgG was detected in MEF only with concomitant IgG in serum. Antibodies to pneumolysin occurred in no relation to bacterial findings in MEF. On the contrary, IgG class antibodies to capsular polysaccharides, most likely serum-derived, were detected less often in MEF samples positive for pneumococcus than for other bacteria.
[Can preoperative urodynamic examination allow us to predict the risk of incontinence after radical prostatectomy?]. (1999)

The incidence of preoperative detrusor instability in our series was high, but little correlation was found between this finding and postoperative incontinence.
N.m.r. spectra of silicon hydride derivatives. Part 6.—Group 5 trisilyls (1966)

The proton magnetic resonance spectra of the group 5 trisilyls are reported, including the satellite spectra due to 29Si at natural abundance. A double resonance experiment shows that the two 29SiH coupling constants in P(SiH3)3 have the same sign. The phosphorus spectrum of the latter is described, and J(29SiP) tentatively assigned.
Interactions between extended and localized states in superlattices (1990)

We have observed electric-field-induced interactions between the extended states of a (40 \AA{})-(15 \AA{}) GaAs-${\mathrm{Ga}}_{0.65}$${\mathrm{Al}}_{0.35}$As superlattice and the localized state of an 80-\AA{} terminating GaAs well. At fields such that the energy of an extended state was close to that of the localized level, low-temperature (5-K) photocurrent spectra associated with interband transitions exhibited three pronounced doublets of peaks with characteristic resonant and anticrossing behavior. As the two levels approach each other, the initially asymmetrical peak intensities first become of comparable strengths and then exchange their roles in the resulting asymmetrical peak intensities as the states begin to repel each other. A comparison of the experimental results with numerical solutions of Schr\"odinger's equation showed that the doublets result from the interaction of the localized state with the three superlattice states of highest energy, centered aroung its last three wells.
Modification of the grain boundary microstructure of the austenitic PCA stainless steel to improve helium embrittlement resistance. [14Cr-16Ni-2. 5Mo-. 25Ti-. 4Si-. 05C] (1986)

Grain boundary MC precipitation was produced by a modified thermal-mechanical pretreatment in 25% cold worked (CW) austenitic prime candidate alloy (PCA) stainless steel prior to HFIR irradiation. Postirradiation tensile results and fracture analysis showed that the modified material (B3) resisted helium embrittlement better than either solution annealed (SA) or 25% CW PCA irradiated at 500 to 600/sup 0/C to approx.21 dpa and 1370 at. ppM He. PCA SA and 25% CW were not embrittled at 300 to 400/sup 0/C. Grain boundary MC survives in PCA-B3 during HFIR irradiation at 500/sup 0/C but dissolves at 600/sup 0/C; it does not form in either SA or 25% CW PCA during similar irradiation. The grain boundary MC appears to play an important role in the helium embrittlement resistance of PCA-B3.
Correlation between Protonic Conductivity and Structure of Phosphate Glasses for Intermediate Temperature Fuel Cells (2013)

We measured NMR, Raman spectra and AC impedance for BaO-ZnO-P 2 O 5 glasses. The short-range order of these glasses was based on metaphosphate ( Q P 2 ) structure. A part of O-P-O bonding was broken and the mobile proton concentration increased for ternary BaO-ZnO-P 2 O 5 glasses. The protonic conductivity was 2 × 10 -7 S/cm for 30 mol%ZnO-10 mol%BaO-60 mol%P 2 O 5 glass at 200 o C. Co-doping of the cations with different coordinate numbers is effective to improve the protonic conductivity for phosphate glasses.
<title>Assessment of breathing effort by means of a fiber optic sensor</title> (1997)

A sensor for measuring chest circumference by means of an optical fiber has been developed. The method is based on the measurement of light transmitted through a bent optical fiber, which is connected to an elastic band, wrapped around the chest, and whose radius of curvature changes due to the respiratory act. The amount of transmitted light is related to the radius of curvature of the fiber which depends on the chest circumference. The output of the respiratory sensor was checked qualitatively by changing the respiration depth. The changes in breathing effort were clearly demonstrated in the sensor output recording. The respiratory effort was also correlated with the heart rate, measured by photoplethysmography. Statistically significant correlation was found between the lungs' volume and the heart rate, but the correlation coefficient was not high. The magnitude of the breathing depth and the height of the corresponding respiratory changes of the heart cycle period were not correlated.
c-Flip overexpression affects satellite cell proliferation and promotes skeletal muscle aging (2010)

This study shows that forcing c-Flip overexpression in undifferentiated skeletal myogenic cells in vivo results in early aging muscle phenotype. In the transgenic mice, adult muscle histology, histochemistry and biochemistry show strong alterations: reduction of fibers size and muscle mass, mitochondrial abnormalities, increase in protein oxidation and apoptosis markers and reduced AKT/GSK3β phosphorylation. In the infant, higher levels of Pax-7, PCNA, P-ERK and active-caspase-3 were observed, indicating enhanced proliferation and concomitant apoptosis of myogenic precursors. Increased proliferation correlated with NF-κB activation, detected as p65 phosphorylation, and with high levels of embryonic myosin heavy chain. Reduced regenerative potential after muscle damage in the adult and impaired fiber growth associated with reduced NFATc2 activation in the infant were also observed, indicating that the satellite cell pool is prematurely compromised. Altogether, these data show a role for c-Flip in modulating skeletal muscle phenotype by affecting the proliferative potential of undifferentiated cells. This finding indicates a novel additional mechanism through which c-Flip might possibly control tissue remodeling.
Early luminal deterioration following successful percutaneous transluminal coronary angioplasty (1994)

In order to develop a predictive model for the risk of early lesion deterioration following successful coronary balloon angioplasty (PTCA) based on clinical, pre-angioplasty and procedural characteristics, 154 lesions in 146 consecutive patients undergoing successful PTCA for stable/unstable angina were examined by quantitative coronary analysis immediately after and within 24 h of angioplasty. An angiographic complication score was used prospectively, classifying the lesion morphology post-PTCA into class 0: no complication and classes 1 to 3, according to purely descriptive morphological characteristics. Significant deterioration, defined as a decrease in minimal luminal diameter of more than 2 standard deviations of duplicate measurements post-intervention (0.54 mm; 95% confidence limit for variability using quantitative angiography) was found in 28 lesions (18%), and a total reocclusion in seven lesions (5%). The angiographic complication score (P = 0.019), prior to myocardial infarction (P = 0.076), minimal luminal diameter immediately post-intervention (P = 0.021) and gain of PTCA (P = 0.042) were found to be independently predictive of early lesion deterioration by multiple logistic regression analysis. Identification of these factors and their associated risk should improve success, and understanding of the early vascular response following coronary angioplasty. Moreover, these results have implications for clinical restenosis studies, particularly those assessing the effect of pharmacological interventions on late restenosis rates.

Diastereoisomers of Platinum(II) Complexes with Chiral <i>N</i>-Substituted 1,2-Diamines. I. Structure and Isomerization of Dichloro{(<i>R</i>)-2-[(2-methyl-2-aminopropyl)amino]-1-butanol}platinum(II) (1992)

Abstract Square-planar complexes with the formula [PtCl2(R-Hb-Mepn)], where R-Hb-Mepn is (R)-2-[(2-methyl-2-aminopropyl)amino]-1-butanol CH3CH2CH(CH2OH)NHCH2C(CH3)2NH2, were synthesized and separated into two diastereoisomers. On the basis of CD spectroscopic and X-ray crystallographic analyses, (+)300- and (−)300-isomers were determined to have the R-nitrogen center with λ chelate ring and the S-nitrogen center with δ chelate ring, respectively. R(N)-[PtCl2(R-Hb-Mepn)] crystallizes in the monoclinic space group P21 with a = 8.809 (1), b = 8.9960 (4), c = 8.536 (1) Å, β = 108.787 (5)°, Z = 2, R = 0.042, and RW = 0.062. S(N)-[PtCl2(R-Hb-Mepn)] crystallizes in the orthorhombic space group P212121 with a = 9.287 (1), b = 14.831 (1), c = 9.141 (1) Å, Z = 4, R = 0.029, and RW = 0.034. 1H NMR spectra indicate that R-Hb-Mepn chelate rings take fixed conformation in acidic D2O solution. At high temeprature (90–95 °C), the conversion of the R(N)-isomer to the S(N)-isomer occurred easily. The R(N)-[PtCl2(R-Hb-Mepn)] and S(N)-[PtCl2(R-Hb-Mepn)], respectively, show the opposite Cotton effect to that of the reported complexes R(N)-[PtCl2(S-Me-pn)] and S(N)-[PtCl2(S-Me-pn)] (S-Me-pn = (S)-1-methylamino-2-aminopropane). The kinetic data of a reversible inversion reaction at the nitrogen were consistent with the usual base catalyzed mechanism.
Contact with host cells induces a DNA repair system in pathogenic <i>Neisseriae</i> (2004)

DNA repair systems play a major role in maintaining the integrity of bacterial genomes. Neisseria meningitidis, a human pathogen capable of colonizing the human nasopharynx, possesses numerous DNA repair genes but lacks inducible DNA repair systems such as the SOS response, present in most bacteria species. We recently identified a set of genes upregulated by contact with host cells. An open reading frame having high homology with the small subunit of Escherichia coli exonuclease VII (xseB) belongs to this regulon. The increased sensitivity of a mutant in this coding sequence to UV irradiation, alkylating agent and nalidixic acid demonstrates the participation of this gene in meningococcal DNA repair. In addition, the upregulation of the transcription of this open reading frame upon interaction of N. meningitidis with host cells increased not only the bacterial ability to repair its DNA but also the rate of phase variation by frameshifting. Together these data demonstrate that N. meningitidis possesses an inducible DNA repair system that might be used by the bacteria to adapt to its niches when it is colonizing a new host.
Amelioration of Superoxide Dismutase on Ventilator-Induced Lung Injury by Suppressing Leukocyte in the Lungs and Systemic Circulation (2013)

Superoxide dismutase (SOD) is a free radical scavenger and a broad-spectrum antioxidant. Its anti-inflammatory and immunomodulatory effects have recently been noted. We studied the effects of this antioxidant on lung damage, oxidative stress, and inflammation in a model of ventilator-induced lung injury (VILI), using 8- to 12-wk-old Sprange-Dawley rats (n = 40). Animals were randomized and evenly divided into two experimental groups, low tidal volume (V(T)) ventilation (V(T) = 9 ml/kg) and high V(T) ventilation (V(T) = 28 ml/kg). Each group was evenly divided into two subgroups: ten animals were treated with superoxide dismutase (SOD; 10,000 U/kg i.v., 2 h prior to the ventilation) and the rests were treated with vehicle. Lung injury was evaluated by histological examination, and cells counts of red blood cells (RBC) and white blood cells (WBC) in the alveoli and the septal wall thickness in lung tissues and serum lactate dehydrogenase (LDH). The lung permeability was assessed by the wet-to-dry weight ratio (W/D), lung weight to body weight ratio (LW/BW) and protein concentration in broncholavage fluid (BALF). Levels of oxidative stress and lipid peroxidation in the lungs were evaluated by tissue malondialdehyde (MDA) and methylguanidine (MG) in BALF, respectively. SOD pretreatment significantly decreased WBC counts in systemic circulation and in alveoli, and effectively attenuated high V(T) ventilation induced lung injury by reducing hyaline membrane development, septal wall thickness, lung W/D and LW/BW and serum LDH in relation to those of the control. In addition, lung tissues MDA and MG in BALF were also notably reduced.
Administration of Silica Sensitizes Lipopolysaccharide Responsiveness of Murine Macrophages but Inhibits T and B Cell Priming by Inhibition of Antigen Presenting Function (1998)

Macrophages play a key role in natural host defense against infection by a variety of pathogens. In addition, macrophages initiate the development of acquired immunity via antigen processing and presentation. The role of macrophages in resistance to pathogens, the development of autoimmune diseases and the induction of acquired immunity has been studied by treatment of rodents with reagents which are cytotoxic. We have studied the effects of one such reagent, silica, on the function of spleen macrophages and peritoneal exudate cells (PEC). Intraperitoneal administration of silica caused the accumulation of spleen macrophages and neutrophils, reduction in the number of B cells and had a modest effect on T cell abundance. The percentage of CD11b+ PEC was not affected by silica treatment but total PEC recovery was diminished 5-8 fold. Silica treatment did not cause release of TNF-alpha or IL-1-beta but, when stimulated with lipopolysaccharide (LPS) in vitro after silica treatment, PEC or spleen macrophages produced elevated levels of both cytokines compared to controls. In contrast, release of IL-12 from non-LPS treated PEC was stimulated 4-5 fold by silica treatment. In addition, sensitivity to LPS toxicity in vivo was significantly enhanced by silica. The ability of macrophages to present antigen to a T cell clone in vitro was found to be dramatically inhibited by silica treatment, as was the ability to prime antigen-specific T cells and B cells by antigen injection. Collectively these data demonstrate that silica treatment enhances macrophage sensitivity to LPS exposure but inhibits antigen processing and presentation.
New serological markers for the differential diagnosis of autoimmune limbic encephalitis<sup>1)</sup> (2012)

Abstract Recently, several novel autoantibodies have been identified which are closely associated with different subtypes of autoimmune encephalitis. These antibodies are directed against structures located on the neuronal cell surface: glutamate receptors (types NMDA and AMPA), GABA B receptors, as well as the voltage-gated potassium channel-associated proteins LGI1 and CASPR2. They are much more common than the classical paraneoplastic antibodies (anti-Hu, -Yo, -Ri, -Ma, -CV2, -amphiphysin), less frequently associated with a tumor, and the corresponding clinical syndromes respond significantly better to immunotherapy. Monospecific detection of these autoantibodies in the serum or cerebrospinal fluid of patients is primarily performed by indirect immunofluorescence using transfected HEK293 cell lines recombinantly expressing the membrane-associated target antigens. Owing to the symptom overlap of the respective disorders, it is highly appropriate to determine these parameters in parallel for each patient (autoantibody profiles). Early diagnosis (substantially supported by the serological laboratory), the immediate initiation of immunotherapeutic intervention and, in cases of paraneoplastic etiology, tumor resection are crucial for prognosis. In our own investigations, antibodies against glutamate receptors (type NMDA) are most frequently found among the newly identified forms of autoimmune encephalitis, accounting for 42% of cases. In laboratory practice, one-third of positive reactions were caused by an autoantibody whose determination was not requested by the clinician. Considering the urgency for therapeutic measures in positive cases, these findings substantiate the need to implement multiparametric serological test systems in this diagnostic area.
A Statistical Approach to Material Classification Using Image Patch Exemplars (2009)

In this paper, we investigate material classification from single images obtained under unknown viewpoint and illumination. It is demonstrated that materials can be classified using the joint distribution of intensity values over extremely compact neighborhoods (starting from as small as 3 \times 3 pixels square) and that this can outperform classification using filter banks with large support. It is also shown that the performance of filter banks is inferior to that of image patches with equivalent neighborhoods. We develop novel texton-based representations which are suited to modeling this joint neighborhood distribution for Markov random fields. The representations are learned from training images and then used to classify novel images (with unknown viewpoint and lighting) into texture classes. Three such representations are proposed and their performance is assessed and compared to that of filter banks. The power of the method is demonstrated by classifying 2,806 images of all 61 materials present in the Columbia-Utrecht database. The classification performance surpasses that of recent state-of-the-art filter bank-based classifiers such as Leung and Malik (IJCV 01), Cula and Dana (IJCV 04), and Varma and Zisserman (IJCV 05). We also benchmark performance by classifying all of the textures present in the UIUC, Microsoft Textile, and San Francisco outdoor data sets. We conclude with discussions on why features based on compact neighborhoods can correctly discriminate between textures with large global structure and why the performance of filter banks is not superior to that of the source image patches from which they were derived.
Recovery of RNA synthesis from the DHFR gene following UV-irradiation precedes the removal of photolesions from the transcribed strand (1999)

It is thought that recovery of RNA synthesis following UV-irradiation is closely related to the removal of UV-induced lesions from the transcribed strand of active genes. To test this hypothesis, nascent RNA synthesis from three different locations within the DHFR gene in CHO cells was assessed following exposure to UV light (254 nm). Using both in vivo RNA labeling as well as the nuclear run-on technique, it was found that RNA synthesis from the middle and the 3'-end of the gene was inhibited within 20 min by approximately 30 and 70%, respectively, while RNA synthesis from the 5'-end of the DHFR gene was enhanced. RNA synthesis from the middle portion of the gene fully recovered within 30-45 min of post-UV incubation, while recovery was slower from the 3'-end of the gene. Compared with previously published data for the kinetics of removal of UV-induced DNA lesions from the 5'-half of the DHFR gene in these cells, it is concluded that RNA synthesis resumed significantly faster in this region than could be accounted for by the removal of photolesions from the transcribed strand. Thus, although RNA synthesis was initially inhibited by UV-induced photolesions, the results suggest that RNA polymerase II was able to bypass these lesions prior to their removal.
Growth and storage of YAC clones in Hogness Freezing Medium (1997)

To date, frozen storage of YAC libraries have relied on the administration of glycerol to the medium subsequent to cell growth. By adding Hogness Freezing Medium prior to inoculation, cultures can be frozen directly after cell growth, with no adverse effect on the stability of the YAC DNA or on the viability of the cells even after repeated freezing and defrosting. Although a relatively simple modification, the procedure notably improves the handling of YAC libraries and significantly reduces the risk of contamination, especially when dealing with large numbers of clones.
Stimulated Raman scattering of long XeCl laser pulses in multimode silica fibers (1998)

For the first time stimulated Raman scattering (SRS) in multimode silica fibers pumped with long XeCl laser pulses has been observed. The spectral and temporal development of SRS both experimentally and theoretically have been studied. Two orders of SRS have been obtained in the 311 divided by 317 nm spectral region. The experimental result are in good agreement with computer simulations of SRS in which effects of self- and cross-phase modulation and group velocity dispersion are negligible. In the numerical model are included experimentally measured spectra of the Raman gain curve and the pump laser spectra.
Studies on the relationship between the molecular structure and the catabolism of insulin (1977)

The catabolism of insulins modified at the A1, B1 or B29 positions or containing a synthetic crosslink between the A1 and B29 positions has been studied in vivo and in vitro. The metabolic clearance rates (MCR) of insulin, proinsulin and chemically modified insulins have been measured by a priming-dose constant infusion technique in greyhounds. Insulins modified at A1 and B29, particularly the crosslinked materials, had markedly lowered MCR's whilst B1 analogues did not differ from insulin. Proinsulin and the A1-B29 crosslinked materials showed a markedly lowered degradability by glutathione-insulin transhydrogenase.
