Anti-Rh(D) IgG Subclasses and Severity of Rh Hemolytic Disease of the Newborn (1990)

The influence of anti-Rh(D) IgG subclasses on the severity of hemolytic disease of the newborn was examined in 98 pregnancies. Disease was severe in 19 of 32 cases in which only IgGl was detected, 40 of 63 cases in which IgGl and IgG3 were found and 0 of 3 cases in which only IgG3 was detected. When both IgGl and IgG3 anti-D were present, hemolytic disease was more severe than when IgGl alone was detected. The earliest onset of hydrops was at 20 weeks gestation in the IgGl+IgG3 anti-Rh group, and at 27 weeks gestation in the IgGl group.

Possibility of spontaneous circulation of a gas mixture in a pulse-periodic laser (1978)

An analysis is made of gasdynamic processes in an electrically pumped gasdynamic CO2 laser. It is shown that, in principle, it is possible to use the energy of shock waves resulting from pulsed evolution of energy in a discharged gap to drive a gas mixture along a closed duct. This is done by placing a nonreturn valve at the entry to the discharge chamber and an acoustic resonator of a certain length at the exit.
Aragonite−Hydroxyapatite Conversion in Gastropod (Abalone) Nacre (1998)

From studies of geological and coral skeleton aragonite, it was previously proposed that aragonite converts hydrothermally to hydroxyapatite (HA) in phosphate solution by a solid-state topotactic ion-exchange reaction in which the HA retains the orientation of the original aragonite. The present investigation of this reaction in gastropod shell nacre suggests instead that conversion for this biomineral proceeds via dissolution-recrystallization, with the preferred orientation of the product determined by the flux direction of the solution through the material. Conversions of various CaCO3 biominerals in aqueous (NH4)2HPO4 at 140−260 °C show that for gastropod nacre alone, sample form and internal ultrastructure are largely preserved and a unique preferred orientation arises: with reaction time, HA nanocrystallites are increasingly oriented with their c-axes perpendicular to the c-axis of the original aragonite. In contrast, other CaCO3 biominerals either disintegrate to HA powder or contain HA crystallites with random orientation or the orientation of the original aragonite. We suggest that the organic matrix of gastropod nacre channels the reaction solution through the material vertically between stacks of aragonite tablets so that sample form and internal ultrastructure are preserved and the HA predominantly adopts a perpendicular c-axis orientation. Other properties of HA-converted gastropod nacre are also discussed.
Yapsins Are a Family of Aspartyl Proteases Required for Cell Wall Integrity in <i>Saccharomyces cerevisiae</i> (2005)

The yeast cell wall is a crucial extracellular organelle that protects the cell from lysis during environmental stress and morphogenesis. Here, we demonstrate that the yapsin family of five glycosylphosphatidylinositol-linked aspartyl proteases is required for cell wall integrity in Saccharomyces cerevisiae. Yapsin null mutants show hypersensitivity to cell wall perturbation, and both the yps1Delta2Delta mutant and the quintuple yapsin mutant (5ypsDelta) undergo osmoremedial cell lysis at 37 degrees C. The cell walls of both 5ypsDelta and yps1Delta2Delta mutants have decreased amounts of 1,3- and 1,6-beta-glucan. Although there is decreased incorporation of both 1,3- and 1,6-beta-glucan in the 5ypsDelta mutant in vivo, in vitro specific activity of both 1,3- and 1,6-beta-glucan synthesis is similar to wild type, indicating that the yapsins affect processes downstream of glucan synthesis and that the yapsins may be involved in the incorporation or retention of cell wall glucan. Presumably as a response to the significant alterations in cell wall composition, the cell wall integrity mitogen-activated kinase signaling cascade (PKC1-MPK pathway) is basally active in 5ypsDelta. YPS1 expression is induced during cell wall stress and remodeling in a PKC1-MPK1-dependent manner, indicating that Yps1p is a direct, and important, output of the cell wall integrity response. The Candida albicans (SAP9) and Candida glabrata (CgYPS1) homologues of YPS1 complement the phenotypes of the yps1Delta mutant. Taken together, these data indicate that the yapsins play an important role in glucan homeostasis in S. cerevisiae and that yapsin homologues may play a similar role in the pathogenic yeasts C. albicans and C. glabrata.

The use of a novel tobacco-substitute sheet and smoke dilution to reduce toxicant yields in cigarette smoke (2011)

The Institute of Medicine encouraged the pursuit and development of potential reduced-exposure products, tobacco products that substantially reduce exposure to one or more tobacco toxicants and can reasonably be expected to reduce the risk of one or more specific diseases or other adverse health effects. One approach to reducing smoke toxicant yields is to dilute the smoke with glycerol. We report chemical, biological and human exposure data related to experimental cigarettes containing up to 60% of a novel glycerol containing "tobacco-substitute" sheet. Analysis of mainstream smoke from experimental cigarettes showed reductions in yields of most measured constituents, other than some volatile species. In vitro toxicological tests showed reductions in the activity of smoke particulates in proportion to their glycerol content. Human exposure to nicotine was reduced by a mean of 18% as determined by filter studies and by 14% using 24h urinary biomarker analysis. Smoke particulate exposures were reduced by a mean of 29% in filter studies and NNK exposure by similar amounts based on urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol concentrations. These results show that reducing exposure to some smoke toxicants is possible using a tobacco-substitute sheet, although some smoke toxicants, and the sensory attributes of the smoke, remain as technical challenges.
Inflammation-induced Uptake and Degradation of the Lymphatic Endothelial Hyaluronan Receptor LYVE-1 (2007)

The hyaluronan receptor LYVE-1 is selectively expressed in the endothelium of lymphatic capillaries, where it has been proposed to function in hyaluronan clearance and hyaluronan-mediated leukocyte adhesion. However, recent studies suggest that hyaluronan homeostasis is unperturbed in LYVE-1(-/-) mice and that lymphatic adhesion/transmigration may be largely mediated by ICAM-1 and VCAM-1 rather than LYVE-1. Here we have explored the possibility that LYVE-1 functions during inflammation and report that the receptor is down-regulated by pro-inflammatory cytokines. Using cultured primary lymphatic endothelial cells, we show that surface expression of LYVE-1 is rapidly and reversibly lost after exposure to tumor necrosis factor-alpha (TNFalpha) and TNFbeta via internalization and degradation of the receptor in lysosomes, coupled with a shutdown in gene expression. Curiously, internalization does not result in significant uptake of hyaluronan, a process that is largely insensitive to the novel LYVE-1 adhesion blocking monoclonal antibody 3A, and proceeds almost equally in resting and inflammation-activated lymphatic endothelial cells. Finally, we show that TNF can induce down-modulation of LYVE-1 in ex vivo murine dermal tissue explants and present evidence that the process occurs in vivo, in the context of murine allergen-induced skin inflammation. These findings suggest that LYVE-1 can function independently of hyaluronan and have implications for the use of LYVE-1 as a histological marker for lymphangiogenesis in human pathology.

The surface variant antigens of <i>Plasmodium falciparum</i> contain cross-reactive epitopes (2001)

Plasmodium falciparum parasites evade the host immune system by clonal expression of the variant antigen, P. falciparum erythrocyte membrane protein 1 (PfEMP1). Antibodies to PfEMP1 correlate with development of clinical immunity but are predominantly variant-specific. To overcome this major limitation for vaccine development, we set out to identify cross-reactive epitopes on the surface of parasitized erythrocytes (PEs). We prepared mAbs to the cysteine-rich interdomain region 1 (CIDR1) of PfEMP1 that is functionally conserved for binding to CD36. Two mAbs, targeting different regions of CIDR1, reacted with multiple P. falciparum strains expressing variant PfEMP1s. One of these mAbs, mAb 6A2-B1, recognized nine of 10 strains tested, failing to react with only one strain that does not bind CD36. Flow cytometry with Chinese hamster ovary cells expressing variant CIDR1s demonstrated that both mAbs recognized the CIDR1 of various CD36-binding PfEMP1s and are truly cross-reactive. The demonstration of cross-reactive epitopes on the PE surface provides further credence for development of effective vaccines against the variant antigen on the surface of P. falciparum-infected erythrocytes.

Efficacy of manual lymphatic drainage in preventing secondary lymphedema after breast cancer surgery. (2012)

This study evaluated the effectiveness of manual lymphatic drainage (MLD) in the prevention of secondary lymphedema after treatment of breast cancer. The study consisted of 67 women, who underwent breast surgery for primary breast cancer. From the second day of surgery, 33 randomly chosen women were given MLD. The control group consisted of 34 women who did not receive MLD. Measurements of the volumes of both the arms were taken before surgery and on days 2, 7, 14, and at 3 and 6 months after surgery. At 6 months after breast cancer surgery, among the women who did not undergo MLD, a significant increase in the arm volume on the operated side was observed (p=0.0033) when compared with the arm volume before surgery. At this time, there was no statistically significant increase in the volume of the upper limb on the operated side in women who underwent MLD. This study demonstrates that regardless of the surgery type and the number of the lymph nodes removed, MLD effectively prevented lymphedema of the arm on the operated side. Even in high risk breast cancer treatments (operation plus irradiation), MLD was demonstrated to be effective against arm volume increase. Even though confirmatory studies are needed, this study demonstrates that MLD administered early after operation for breast cancer should be considered for the prevention of lymphedema.

The Reaction of 4-Substituted Aryl Isocyanates with NaBH4/Trifluoroacetic Acid (TFA) (1999)

Treatment of 4-substituted aryl isocyanates (cf. 2a-f) with NaBH4/TFA leads to the corresponding 4-substituted N,N-bis(2,2,2-trifluorethyl)aniline derivatives (3a-d) in excellent yield except where an electron-withdrawing group is present (cf. 2e) or the para-position is open (cf. 2f).
An Exact Model of Acoustic Radiation in Enclosed Spaces (1995)

The acoustician's armory for modeling radiation of sound in enclosed spaces has traditionally been limited to the use of scale modeling, image theory, ray tracing, and the consideration of only some of the enclosure boundaries. Acoustic finite-element analysis is now reaching maturity and offers the designer of acoustic spaces the potential to produce exact computer models. The finite-element technique is discussed as applied to acoustic spaces, illustrating the facility to model complex structures, absorption, and multiple sources.

[Sphingomonas sp.: an important microbial resource for biopolymer synthesis]. (2009)

The genus Sphingomonas was established in 1990. Sphingomonas spp. synthesize sphingans, structurally related biopolymers such as gellan, welan and diutan. At present, only gellan is applied widely in foods and pharmaceuticals. The economic value of other sphingans has not been well explored, and related research of sphingans still remains limited. In the present review, we address the latest taxonomy developments of Sphingomonas, details about structure, characteristics and biosynthetic pathway of sphingans, current knowledge on the molecular genetics and genetic engineering of sphingans. In addition, we indicate future research needs.
A Multiple-Beam Interferometer for Use with Spherical Wavefronts (1967)

A multiple-beam interferometer that permits evaluation of autostigmatic systems is described. A small reference sphere is compared with a spherical wavefront in a manner analogous to the comparison of a plane wavefront with the reference flat in a Fizeau interferometer. To prevent walk-off of the fringes, a field lens is used at the center of curvature of the reference sphere. The instrument described has been used for evaluating spherical mirrors, concentric windows, and lenses.
Component forensics (2009)

Visual sensor technologies have experienced tremendous growth in recent decades, and digital devices are becoming ubiquitous. Digital images taken by various imaging devices have been used in a growing number of applications, from military and reconnaissance to medical diagnosis and consumer photography. Consequently, a series of new forensic issues arise amidst such rapid advancement and widespread adoption of imaging technologies. For example, one can readily ask what kinds of hardware and software components as well as their parameters have been employed inside these devices? Given a digital image, which imaging sensor or which brand of sensor was used to acquire the image? How was the image acquired? Was it captured using a digital camera, cell phone camera, image scanner, or was it created artificially using an imageediting software? Has the image undergone any manipulation after capture? Is it authentic, or has it been tampered in any way? Does it contain any hidden information or steganographic data? Many of these forensic questions are related to tracing the origin of the digital image to its creation process. Evidence obtained from such analysis would provide useful forensic information to law enforcement, security, and intelligence agencies. Knowledge of image acquisition techniques can also help answer further forensic questions regarding the nature of additional processing that the image might have undergone after capture.
New elastomers derived from copolymers of tetrahydrofuran and propylene oxide (1962)

Abstract The homopolymers of tetrahydrofuran, polytetramethylene glycols, may be chain‐extended to form polyurethane elastomers. These materials, while possessing a low glass point temperature, suffer from cold hardening, and it was decided to investigate copolymers of tetrahydrofuran and propylene oxide as elastomer ingredients. The preparation of these copolymers has been achieved by use of a boron trifluoride etherate polymerization catalyst. Details are given of the properties of both the copolymer and derived elastomers at nominal compositions in the range 50–85 wt.‐% of tetrahydrofuran. The copolymers described were synthesized as ingredients for castable elastomers, and in consequence viscosity effects are important. It has been found that no significant increase in viscosity occurs until the tetrahydrofuran content exceeds 75 wt.‐%. This indicates that each side methyl group exerts a screening effect over an average of 13 atoms of the polymer backbones. The mechanical testing of the derived elastomers indicates that the copolymerization of tetrahydrofuran and propylene oxide leads to material possessing a low glass point temperature and much better physical properties than the homopolymer of propylene oxide. The elastic properties of a chain‐extended diol are dependent on the degree of crosslinking and on the incidence of network deficiencies. Network deficiencies are caused by the presence of monofunctional species in the copolymeric diols, and a novel technique for determining diol monofunctionality based on analysis of physical test data was evolved for these studies.
Experimental study of the Doppler shift generated by a vibrating scatterer (2004)

We report an experimental study of the backscattering of a sound wave of frequency f by a surface vibrating harmonically at frequency F (F << f) and amplitude A in the regime where the Doppler effect overcomes bulk nonlinear effects. When the duration to of the analyzed time series of the scattered wave is small compared to the vibration period, the power spectrum of the backscattered wave is proportional to the probability density function of the scatterer velocity, which presents two peaks shifted from f by roughly 2fAomega/c (omega = 2piF). On the contrary, when t0 >> F(-1), sidebands at frequencies f +/- nF (n integer) appear in the power spectrum, which are due to the phase modulation of the backscattered wave induced by its reflection on a moving boundary. We use the backscattered power spectrum to validate the phase modulation theory of the Doppler effect in the latter case for 2kA << 1 and 2kA approximately > 1 (k = 2pif/c, where c is the wave velocity) and we test the validity of an acoustic nonintrusive estimator of A as a function of power spectrum bandwidth and of A itself.
