Role of interleukin-4 in human immunoglobulin E formation in hu-PBL-SCID mice. (1994)

We studied the role of IL-4 in human IgE formation in severe combined immunodeficient mice engrafted with peripheral blood mononuclear leukocytes (hu-PBL-SCID). PBL from four nonatopic donors produced only small (< 20 ng/ml) or undetectable amounts of IgE in SCID mice whereas engrafted PBL from seven atopic donors secreted IgE with IgE serum levels reaching a mean +/- SE of 184 +/- 37 ng/ml (n = 20). Serum IgE levels peaked 2-3 wk after PBL transfer and declined thereafter with a half-life of 1-2 wk. In contrast, IgG of all subclasses reached maximum serum levels 5-7 wk after PBL transfer and declined little thereafter. Injection of a neutralizing monoclonal antibody to the human IL-4 receptor (IL-4R) on day 0 inhibited completely the IgE formation and caused an approximate twofold reduction of IgG production of all subclasses. The anti-IL-4 R antibody had no effect on IgE secretion when administered 4 wk after PBL engraftment. Incubation of PBL with IL-4 before engraftment resulted in a 10-fold increase in IgE production and could be further enhanced by 100 fold if, in addition to preincubation with IL-4, IL-4 was injected daily for 5 d after PBL transfer. This treatment with IL-4 also induced two- to threefold increase in IgG levels. IFN-gamma had no effect on either IgE or IgG subclass production. In approximately 50% of the mice, one or more IgG subclasses increased disproportionally 5 wk after PBL injection as a result of monoclonal IgG formation. These data demonstrate that PBL from atopic donors secrete IgE in SCID mice in an IL-4-dependent manner, and that IgE production can be enhanced 10- to 100-fold with exogenous human IL-4 in these mice. This mouse model is amenable for the in vivo study of immunomodulators on human IgE formation.
Antigens from Actinomyces Species and Their Value in Identification (1976)

Actinomyces have a complex antigenic structure that includes neutral cell wall carbohydrate and some polypeptide containing charged antigens. Wall carbohydrate can be prepared in a relatively pure form from cell walls or by DEAE Sephadex chromatography of acid extracts and supernatant culture fluid. Charged antigens are generally eluted in groups by batch-elution from columns. Cell wall carbohydrate can be responsible for species-specific reactions and cross-reactions, and strains may possess more than one cell wall carbohydrate determinant. The charged antigens also can be species specific, but they cause some cross-reactions, particularly those between the A israelii serotypes. Autoclave extracts of strains, tested against antiserums reacting with cell wall carbohydrate, may be valuable in routine identification of isolates.
Compact Peptoid Molecular Brushes for Nanoparticle Stabilization (2022)

Controlling the interfaces and interactions of colloidal nanoparticles (NPs) via tethered molecular moieties is crucial for NP applications in engineered nanomaterials, optics, catalysis, and nanomedicine. Despite a broad range of molecular types explored, there is a need for a flexible approach to rationally vary the chemistry and structure of these interfacial molecules for controlling NP stability in diverse environments, while maintaining a small size of the NP molecular shell. Here, we demonstrate that low-molecular-weight, bifunctional comb-shaped, and sequence-defined peptoids can effectively stabilize gold NPs (AuNPs). The generality of this robust functionalization strategy was also demonstrated by coating of silver, platinum, and iron oxide NPs with designed peptoids. Each peptoid (PE) is designed with varied arrangements of a multivalent AuNP-binding domain and a solvation domain consisting of oligo-ethylene glycol (EG) branches. Among designs, a peptoid (PE5) with a diblock structure is demonstrated to provide a superior nanocolloidal stability in diverse aqueous solutions while forming a compact shell (∼1.5 nm) on the AuNP surface. We demonstrate by experiments and molecular dynamics simulations that PE5-coated AuNPs (PE5/AuNPs) are stable in select organic solvents owing to the strong PE5 (amine)-Au binding and solubility of the oligo-EG motifs. At the vapor-aqueous interface, we show that PE5/AuNPs remain stable and can self-assemble into ordered 2D lattices. The NP films exhibit strong near-field plasmonic coupling when transferred to solid substrates.
Multi-h modulation indexes selection using the PBIL algorithm (2002)

Multi-h CPFSK modulation is a scheme that is simple to implement, spectrally efficient in terms of bandwidth and has inherent error correction properties. It is the purpose of this research to find specific limits of the niche in which multi-h finds itself. The vehicle of comparisons between modulation and coding schemes is the probability of error tradeoff against signal to noise ratios. Multi-h requires large parameter sets to obtain low probabilities of error. Huge numbers of combinations may need to be investigated. A fast efficient and thorough search needs to be performed. A search algorithm based on the genetic algorithm and known as the 'population based incremental learning' (PBIL) algorithm is thought to be ideal.
Photosensitization of Natural and Synthetic SnO2 Single Crystals with Dyes and Quantum Dots (2016)

The surface preparation and photosensitization of highly oriented natural and synthetic SnO2 single crystals is investigated for the first time. Incident photon conversion efficiency (IPCE) spectra for SnO2 single crystals sensitized with both CdSe quantum dots (QD) and the thiacyanine dye are measured and interpreted. We discuss the influence of crystal face and doping density on the IPCE spectral response and magnitude. Advantages of SnO2 as a substrate for sensitization studies are also pointed out.
P3‐561: ADHERENCE TO THE MIND DIET IS ASSOCIATED WITH BETTER COGNITION IN THE FRAMINGHAM HEART STUDY (2018)

Adherence to the Mediterranean-DASH diet Intervention for Neurodegeneration Delay (MIND) diet has shown promise as a strategy to promote healthy cognitive aging. However, such findings require replication in independent cohorts. Accordingly, we examined whether adherence to the MIND diet was associated with cognitive markers of preclinical Alzheimer's disease (AD) or vascular brain injury (VBI) in 2,092 dementia- and stroke-free participants (age 62 [SD, 9] years, 46% men) from the community-based Framingham Heart Study Offspring cohort. Dietary intake was assessed at three time points using a validated semi-quantitative Harvard food frequency questionnaire (FFQ). Dietary components were scored in accordance with the original MIND diet papers; there are 15 dietary components in which 10 are considered healthy and five are considered unhealthy with overall scores ranging from 0-15. We generated a MIND diet score by averaging across 3 Heart Study examination cycles (exams 5 [1991-1995], 6 [1995-1998], and 7 [1998-2001]) prior to neuropsychological (NP) assessment. Markers of general cognition, preclinical AD (episodic memory), and VBI (executive function, processing speed, abstract reasoning and visual memory) were measured using a detailed NP battery administered close to examination cycle 7. We used a series of linear regression models to relate the cumulative MIND diet score to performance across each cognitive outcome, adjusting for age, sex, calorie intake, education, the time interval between exam7 and cognitive assessment, BMI, physical activity, diabetes, smoking, depression, CVD, hypertension and total cholesterol to HDL ratio. Every unit increase in the MIND diet score was associated with superior global cognition [β±SE (p): 0.04±0.01(<0.01)], episodic memory [0.12±0.05(0.01)], processing speed [0.01±0.004(<0.01)], abstract reasoning [0.11± 0.04(0.01)], and visual memory [0.12±0.04(<0.01)]. Significant interactions were observed with the APOE genotype. Stratified analyses revealed that MIND diet adherence was associated with superior global cognition [0.08±0.02(0.001)], episodic memory [0.42±0.11(<0.001)], executive function [0.02±0.01(0.04)], and processing speed [0.03±0.01(<0.01)] among APOE ɛ4 carriers. Higher adherence to the MIND diet was independently associated with markers of preclinical AD and VBI. Further studies are needed to elucidate whether adopting the MIND diet can alter cognitive trajectories with aging, particularly in APOE ɛ4 carriers.
A Self-Powered CMOS Reconfigurable Multi-Sensor SoC for Biomedical Applications (2014)

A highly adaptive multi-sensor SoC comprising four integrated on-chip sensors and a smart wireless acquisition system is realized in standard CMOS process for the first time. To intelligently process different types (C, R, I, and V) of sensor signals, a linear (R-square is 0.999) and reconfigurable sensor readout is proposed based on switched-capacitor circuit technology. In addition, a dual-input energy harvesting interface with conversion efficiency of 73% is also integrated to pick up light energy and RF power, which potentiates long-term use without battery replacement. The entire SoC occupies die area of 11.25 mm 2 and consumes only 942.9 µW. Experimental results show that four physiological parameters (temperature, glucose and protein concentration, and pH value) can be simultaneously monitored using this chip. This system can be seen as a universal sensor platform. Different types of sensors can be easily integrated into it for convenient use, which dramatically reduces time consuming of building a new sensor system.
Systems Biology of Cancer: A Challenging Expedition for Clinical and Quantitative Biologists (2014)

A systems-biology approach to complex disease (such as cancer) is now complementing traditional experience-based approaches, which have typically been invasive and expensive. The rapid progress in biomedical knowledge is enabling the targeting of disease with therapies that are precise, proactive, preventive, and personalized. In this paper, we summarize and classify models of systems biology and model checking tools, which have been used to great success in computational biology and related fields. We demonstrate how these models and tools have been used to study some of the twelve biochemical pathways implicated in but not unique to pancreatic cancer, and conclude that the resulting mechanistic models will need to be further enhanced by various abstraction techniques to interpret phenomenological models of cancer progression.
Measurement ofZdecays into lepton pairs (1989)

We present measurements by the Mark II experiment of the ratios of the leptonic partial widths of the Z boson to the hadronic partial width. The results are ${\mathrm{\ensuremath{\Gamma}}}_{\mathit{ee}}$/${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{had}}$=0.${037}_{\mathrm{\ensuremath{-}}0.012}^{+0.016}$, =0.${053}_{\mathrm{\ensuremath{-}}0.015}^{0.020}$, and ${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{\ensuremath{\tau}}\mathrm{\ensuremath{\tau}}}$/${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{had}}$=0.${066}_{\mathrm{\ensuremath{-}}0.017}^{+0.021}$, in good agreement with the standard-model prediction of 0.048. From the average leptonic width result, ${\mathrm{\ensuremath{\Gamma}}}_{\mathit{ll}}$/${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{had}}$=0.${053}_{\mathrm{\ensuremath{-}}0.009}^{+0.010}$, we derive ${\mathrm{\ensuremath{\Gamma}}}_{\mathrm{had}}$=1.${56}_{\mathrm{\ensuremath{-}}0.24}^{+0.28}$ GeV. We find for the vector coupling constants of the tau and muon ${\mathit{v}}_{\mathrm{\ensuremath{\tau}}}^{2}$=0.31\ifmmode\pm\else\textpm\fi{}0.${31}_{\mathrm{\ensuremath{-}}0.30}^{+0.43}$ and ${\mathit{v}}_{\mathrm{\ensuremath{\mu}}}^{2}$=0.05\ifmmode\pm\else\textpm\fi{}0.${30}_{\mathrm{\ensuremath{-}}0.23}^{+0.34}$.
Simultaneous neutron powder diffraction and microwave dielectric studies of ammonia absorption in metal–organic framework systems (2018)

Ammonia absorption has been investigated in metal-organic frameworks (UiO-67, HKUST-1 and CPO-27-Co) using custom-built apparatus that allows simultaneous neutron powder diffraction (NPD), microwave dielectric characterisation and out-gas mass spectroscopy of solid-state materials during ammonia adsorption. Deuterated ammonia was flowed through the sample and absorption monitored using mass flow meters and mass spectroscopy. Argon gas was then flowed through the ammoniated sample to cause ammonia desorption. Changes in structure found from NPD measurements were compared to changes in dielectric characteristics to differentiate physisorbed and metal-coordinated ammonia, as well as determine decomposition of sample materials. The results of these studies allow the identification of materials with useful ammonia storage properties and provides a new metric for the measurement of gas absorption within mesoporous solids.
Comparison of the analytical solutionof efficieтcy regenerative rotating heatexchangethe device with resultsof numericalcalculations (2018)

The article is devoted to the thermal-hydraulic calculation of the rotating heat exchanger of a gas turbine engine. More specifically, the purpose of this work is to determine the error of the known analytical calculation of the efficiency of the regenerative heat exchanger in comparison with numerical calculation. Analytical and numerical calculations of the rotating heat exchanger are performed. The main problem of creating a methodology for the analytical solution of processes occurring in rotating heat exchangers is that it is necessary to solve the problem of non-stationary heat transfer from the hot coolant to the coolant through the regenerator packing. The solution of any non-stationary process of heat transfer requires knowledge of the boundary and initial conditions of the process. As initial conditions, it is necessary to use the dependence of the regenerator packing temperature field on the steady state of its operation. Such a relationship can only be obtained after the calculation is completed. In this case, the solution of the heat transfer problem in a rotating heat exchanger is possible using two methodological approaches. The first possibility is a solution by successive approximations. In addition to the fact that such a technique is very time-consuming, it allows us to obtain only a numerical solution of the problem, the possibilities of analysis are limited. The second possibility is the use of one or several assumptions. Such an analytical solution was obtained by Stepanov G.Yu. It is clear that the use of assumptions in analytical analysis or in analytical calculations requires an assessment of the accuracy of the methodology. An estimate of the accuracy of the analytical solution to the efficiency of a rotating heat exchanger is given in the proposed work. It is shown that the error of the analytical solution of the regenerator efficiency in the zone of high regeneration degree values is insignificant in comparison with numerical calculations. Analytical solutions proposed by Stepanov G.Yu., are accessible and effective in the process of creating regenerators. Of particular importance are analytical calculations of the efficiency of regenerators when recording solutions in the form required by the similarity theory. An increase in the error in the analytical calculation of the efficiency of the regenerator is noted with a decrease in the ratio of the water equivalents of the heat-transfer packing of the rotating heat exchanger and coolants (gas and air). Marked increase of error of the analytical calculation of the effectiveness of the Regener-Torah in the decrease of water equivalent heat transfer gaskets. no-return heat exchanger and coolants (gas and air).

Multiuser Successive Maximum Ratio Transmission (MS-MRT) for Video Quality Maximization in Unicast and Broadcast MIMO OFDMA-Based 4G Wireless Networks (2014)

In this paper, we propose a novel low-complexity beamforming algorithm for multiuser successive maximum ratio transmission (MS-MRT) toward space-division multiplexing to achieve video quality maximization in the downlink of a multiuser (MU) multiple-input–multiple-output (MIMO) orthogonal frequency-division multiple-access (OFDMA)-based fourth-generation (4G) wireless network. We compare the performance of this algorithm in terms of system throughput and video quality with the two popular precoding techniques, namely, block diagonalization (BD) and successive optimization (SO). We also compare its performance with the generalized versions of these two algorithms termed coordinated transmit–receive processing (CTR)-BD and CTR-SO algorithms, respectively. Further, we propose an extension of the MS-MRT scheme to broadcast scenarios, termed broadcast successive maximum ratio transmission (BS-MRT), which computes the optimal broadcast beamforming vector to maximize the video quality at each of the broadcast group members while maintaining orthogonality to the previously scheduled user groups. We also demonstrate that the proposed MS-MRT and BS-MRT schemes can be naturally adapted to the context of various MU OFDMA scheduling algorithms such as proportional fairness (PF) and round robin (RR), to name a few, to maximize video quality through optimal scheduling in the presence of a large number of users. We discuss implementations of the proposed MS-MRT scheme in association with these scheduling algorithms for MU unicast and broadcast video transmission scenarios. The simulation results presented in this work rely on the rate models derived using the Joint Scalable Video Model (JSVM) software developed by the Joint Video Team (JVT) and are, thus, readily applicable in practice. The presented results clearly demonstrate the ability of the proposed algorithm to maximize the video quality in comparison with the other competing MU MIMO precoding techniques. Further, employing the proportional fair scheduling algorithm in conjunction with the MS-MRT results in an overall enhancement in the received video quality compared with the RR and max-rate algorithms.

Transparent Insulation Materials (Thermal Conductivity) (1986)

Different kinds of transparent insulation materials were investigated. The thermal conductivity was found to depend mainly on thermal radiation. For this reason it was found to be generally sufficient to classify the materials by only one radiative property. The improvement of thermal insulation by application of a selective absorber was investigated by measurements and calculations. A new configuration to combine a selective absorber with a transparent insulation is proposed. Some spectral measurements were done and compared with calculations. Radiative grey characterization was compared with spectral characterization.
Orientations and reorientational dynamics of methanol enclathrated in β-quinol (hydroquinone) from dielectric and 1H, 2H, and 13C NMR studies (1979)

Dielectric measurements of methanol–β-quinol clathrate between 5 and 300 K show two widely separated relaxation regions associated with relaxation of the components of the methanol dipole moment parallel and perpendicular to the c axis of the crystal. Both are sensitive to the methanol content of the cages. For high methanol content, both components tend to become ordered below the transition at 66 K. NMR studies over a wide range of temperature were made of the H line shape in CH3OD–C6D6O2, D quadrupole coupling constant (DQCC) in CD3OH–C6H6O2 and spin–lattice relaxation of H in CH3OH–C6H6O2 and D in CD3OH–C6H6O2. A 13C chemical shift anisotropy of σ∥-σ⊥=20.6 ppm for CH3OH in a single crystal was obtained at 302 K. The DQCC in CH3OD was 109 kHz at 302 K. The results are consistent with a model of six preferred orientations of methanol, three related by 120° rotation about the c axis and three generated approximately by inversion of the first three through the cage center. In the preferred orientations, the COH plane is parallel to c and the angle of 32° between the CO bond and c below 100 K increases to ∼40° at 300 K.

Anion-exchange blocker enhances cytoplasmic vacuole formation and cell death in serum-deprived mouse kidney epithelial cells in mice (2005)

An anion exchange blocker, DIDS, exhibits anti-apoptotic activity in response to several apoptotic stimuli, but has an opposite effect when apoptosis is induced by serum deprivation. After adding DIDS, serum-deprived MCT cells exhibited vacuole formation in their cytoplasm and underwent cell death. Caspase activity increased with the addition of DIDS to serum-deprived MCT cells, but Z-Asp-CH2-DCB, a caspase inhibitor, did not inhibit cell death in DIDS-treated, serum-deprived MCT cells. Cathepsin is considered to be important for vacuole formation and cell lysis, and pepstatin A, a cathepsin D inhibitor, partially inhibited vacuole formation in DIDS-treated, serum-deprived MCT cells, although caspase activation was not inhibited. 3-Methyladenin inhibited vacuole formation and cell death in DIDS-treated, serum-deprived MCT cells. These results suggest that DIDS-treated serum-deprived MCT cells undergo autophagy, not apoptosis.
