*Basidiomycete allergens: comparison of three <i>Ganoderma</i> species (1993)

High atmospheric concentrations of basidiospores occur in various parts of the world. Ganoderma basidiospores are distinctive, easily identifiable in aeroallergen surveys, and widely abundant. Previous studies showed that Ganoderma basidiospores caused respiratory allergies. Thus, we investigated various extracts (spore, cap, and/or mycelial) of G. meredithae, G. lucidum, and G. applanatum for allergen components. Analyses included radioallergosorbent test (RAST) inhibition and IgE blots from isoelectric focusing (IEF) and SDS-PAGE. RAST inhibition with spores and caps of G. meredithae and G. lucidum showed that spores inhibited caps better than caps inhibited spores. Species differences were minor. Coomassie blue (CB) staining of IEF gels detected at least 23 protein bands (pI 3.6-6.6) in caps of G. meredithae and G. lucidum. G. meredithae spore extracts contained 17 of these (pI 3.6-5.0, 6.6). Spores and caps of G. meredithae contained 13 and 11 allergen bands, respectively, on IEF blots. SDS-PAGE of G. meredithae spore and cap showed one and four bands, respectively, by CB staining, but IgE blots showed 13 bands in cap and 17 in spore. Culture mycelia of G. lucidum and G. applanatum attained significant and essentially constant RAST activity by day 4. Activity was also present in culture supernatant by day 4. Blots of mycelium and supernatant detected a single allergen in day-8 mycelia and subsequently six allergen bands in day-16 mycelia and eight in day-16 supernatant (one appeared as a doublet). These data show that Ganoderma extracts contain a complex mixture of allergens. Differences among species were minor; spores and mycelia are apparently better sources of allergens than caps.
Measurement of the Rate Coefficient for the Recombination of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msup><mml:mrow><mml:mi mathvariant="normal">He</mml:mi></mml:mrow><mml:mrow><mml:mo>+</mml:mo></mml:mrow></mml:msup></mml:mrow></mml:math>with Electrons (1972)

A computer-linked spectroscopic system with a high-sensitivity-resolution product has been used to measure the time-dependent net rate of production of neutral helium atoms resulting from the recombination of ${\mathrm{He}}^{+}$ with electrons in a pulsed helium afterglow at neutral pressures of 1.86 and 44.6 Torr. The recombination-rate coefficient of ${\mathrm{He}}^{+}$ as a function of afterglow time has been obtained by dividing these data by the product of the electron and atomic-ion density as determined from intensity measurements of radiation from bound levels in Saha equilibrium with the free electrons. Simultaneous time-resolved measurement of the electron density with a 35-GHz Fabry-Perot resonator has given the recombination-rate coefficient as a continuous function of electron densities without the need of a priori assumptions about that functional form. The electron temperature as a function of electron density in the recombining afterglow was determined from analyses of time-resolved measurements of the intensity distribution of radiation from the continuum states above the $n^{3}P\ensuremath{\rightarrow}2^{3}S$ Rydberg series in atomic helium. For pressures below a nominal 2 Torr, the resulting parametrization of the recombination-rate coefficient for ${\mathrm{He}}^{+}$ with electrons can be represented as $\ensuremath{\alpha}=7.1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}20}{(\frac{T}{300})}^{\ensuremath{-}4.3}[e]$ ${\mathrm{cm}}^{3}$/sec, where $T$ is the electron temperature and [$e$] the electron density. At higher pressures the rate coefficient is found to decrease as a consequence of associative ionization of the excited states.
In vivo biotinylation demonstrates that reticulated platelets are the youngest platelets in circulation. (1995)

In both mice and humans, a subset of platelets can be identified that shows increased labeling with nucleic acid-specific fluorescent dyes, such as thiazole orange. Termed "reticulated platelets," they have been postulated to be platelets that have recently entered the circulation. Their numbers appear to reflect the rate of new platelet production in a number of clinical and experimental situations. To determine whether reticulated platelets really are the youngest platelets in circulation and to estimate the length of time that they are identifiable after entering the circulation, we have employed a technique of "in vivo biotinylation" in mice that labels the entire cohort of circulating cells with covalently bound biotin. Blood samples can then be double-labeled with fluorescent avidin derivatives and thiazole orange, permitting correlated measurement of both surface biotin content and nucleic acid content. The biotinylation occurs rapidly, is complete within 30 minutes, is stable for several days, and does not appear to alter platelet function. The results show that within 24 hours after in vivo biotinylation, platelets appear in the circulation with decreased levels of biotinylation and that these are the reticulated platelets. The estimated lifespan of reticulated platelets is 1.8 days, and the lifespan of all platelets by this method is 4.5 days, which is in agreement with estimates made by other methods.
Development of an Activity‐Based Probe for Autotaxin (2010)

Autotaxin (ATX), or ecto-nucleotide pyrophosphatase/phosphodiesterase 2 (ENPP2), is a secreted lysophospholipase D that hydrolyses lysophosphatidylcholine into the lipid mediator lysophosphatidic acid (LPA), a mitogen and chemoattractant for many cell types. ATX has been implicated in tumour progression and inflammation, and might serve as a biomarker. Here we describe the development of a fluorescent activity-based probe that covalently binds to the active site of ATX. The probe consists of a lysophospholipid-based backbone linked to a trapping moiety that becomes reactive after phosphate ester hydrolysis, and a Cy5 fluorescent dye to allow visualisation of active ATX. The probe reacts specifically with the three known isoforms of ATX, it competes with small-molecule inhibitors for binding to ATX and allows ATX activity in plasma to be determined. Our activity-based reporter will be useful for monitoring ATX activity in biological fluids and for inhibitor screening.
Resolution, LER, and sensitivity limitations of photoresists (2008)

Recent experimental results and modeling both indicate that whereas it is possible to optimize a photoresist and process to achieve separately a desired resolution or line edge roughness or sensitivity, it will be difficult if not impossible to achieve all three simultaneously using current standard chemically amplified photoresists and processes. This tradeoff among Resolution, Line Edge Roughness (LER) and Sensitivity is termed the RLS tradeoff. Here we review the progress to date of a SEMATECH-funded program to develop an experimentally verified model of the relationship among resolution, LER and sensitivity and use it to determine approaches for "breaking" the RLS tradeoff.
Status of vitamin D, antimicrobial peptide cathelicidin and T helper-associated cytokines in patients with diabetes mellitus and pulmonary tuberculosis (2014)

Pulmonary tuberculosis (PTB) is a high burden infectious disease in China. The immune function is damaged in patients with diabetes mellitus (DM) who are easy to infect with <i>Mycobacterium tuberculosis</i> (Mtb). The growth of Mtb has been shown to be restrained following the administration of vitamin D and antimicrobial peptide cathelicidin (LL-37); however, the effect in patients with DM and PTB remains unclear. Vitamin D can regulate the immune system through Vitamin D receptors expressed in T helper (Th) cells. The aim of the present study was to analyze the status and correlations of vitamin D, LL-37 and Th-associated cytokines in patients with PTB or PTB with DM (DMPTB). Serum 25-hydroxyvitamin D<sub>3</sub> [25(OH)D<sub>3</sub>] levels were measured by liquid chromatography-tandem mass spectrometry, while plasma LL-37 levels were analyzed using a solid-phase enzyme-linked immunosorbent assay. Flow cytometry was used to analyze the levels of Th cytokines, including Th1-associated IFN-γ, Th2-associated IL-4 and Th17-associated IL-17. The results revealed that patients with PTB and DMPTB were vitamin D deficient or had insufficient vitamin D levels. Furthermore, the levels of LL-37, IFN-γ, IL-4 and IL-17 were higher in the PTB and DMPTB groups when compared with the normal controls. These results indicated that vitamin D supplementation is necessary for PTB and DMPTB patients. In addition, LL-37, IFN-γ and IL-17 may be diagnostic indexes that become elevated in the compensatory response caused by Mtb infection. Vitamin D can regulate the immune status in patients suffering from PTB.
Effect of Probenecid and Ranitidine on Urinary Excretion of Lomefloxacin in Rats (1996)

To examine the renal tubular transport pathways of lomefloxacin, a new quinolone antibiotic, the agent was injected intravenously with or without pretreatment with probenecid, an organic anion, or ranitidine, an organic cation, in rats. Urinary excretion of lomefloxacin significantly decreased in the probenecid-treated animals. However, no significant decrease was observed in this parameter by pretreatment with ranitidine. These results suggest that lomefloxacin is mainly secreted in urine by the organic anion transport system, while the pathway mediated by the organic cation transport system is negligible.
Enhancement of Spontaneous Activity by HCN4 Overexpression in Mouse Embryonic Stem Cell-Derived Cardiomyocytes - A Possible Biological Pacemaker (2015)

We generated HCN4-overexpresssing mESC-CMs expressing genes required for impulse conduction, showing rapid spontaneous beating, responding to an If inhibitor and beta-adrenergic receptor agonist, and having pacing ability in an in vitro co-culture system with other excitable cells. The results indicated that these cells could be applied to a biological pacemaker.
A borazaaromatic analogue of isophthalic acid (2001)

A diboradiazaaromatic—2,7-di-tert-butyl-5,9-dihydroxy-5,9-dibora-4,10-diazapyrene-4,10-diium-5,9-diuide—which is a structural analogue of isophthalic acid has been designed and synthesised. This compound is capable of spontaneous dehydration in solution to form linear oligoanhydrides. These oligoanhydrides can be readily hydrolysed to the starting diboradiazaaromatic under appropriate conditions. This unusual reactivity is mirrored in the solid-state behaviour of 2,7-di-tert-butyl-5,9-dihydroxy-5,9-dibora-4,10-diazapyrene-4,10-diium-5,9-diuide. A complex network of hydrogen bonds present in the solid-state structure of the borazaaromatic serve to facilitate a facile solid-state dehydration reaction, once again forming oligoanhydrides of molecular weight greater than 3000 Da.
Efficient Cloth Modeling and Rendering (2001)

Realistic modeling and high-performance rendering of cloth and clothing is a challenging problem. Often these materials are seen at distances where individual stitches and knits can be made out and need to be accounted for. Modeling of the geometry at this level of detail fails due to sheer complexity, while simple texture mapping techniques do not produce the desired quality. In this paper, we describe an efficient and realistic approach that takes into account view-dependent effects such as small displacements causing occlusion and shadows, as well as illumination effects. The method is efficient in terms of memory consumption, and uses a combination of hardware and software rendering to achieve high performance. It is conceivable that future graphics hardware will be flexible enough for full hardware rendering of the proposed method.
Fast and Accurate Entity Recognition with Iterated Dilated Convolutions (2017)

Today when many practitioners run basic NLP on the entire web and large-volume traffic, faster methods are paramount to saving time and energy costs. Recent advances in GPU hardware have led to the emergence of bi-directional LSTMs as a standard method for obtaining per-token vector representations serving as input to labeling tasks such as NER (often followed by prediction in a linear-chain CRF). Though expressive and accurate, these models fail to fully exploit GPU parallelism, limiting their computational efficiency. This paper proposes a faster alternative to Bi-LSTMs for NER: Iterated Dilated Convolutional Neural Networks (ID-CNNs), which have better capacity than traditional CNNs for large context and structured prediction. Unlike LSTMs whose sequential processing on sentences of length N requires O(N) time even in the face of parallelism, ID-CNNs permit fixed-depth convolutions to run in parallel across entire documents. We describe a distinct combination of network structure, parameter sharing and training procedures that enable dramatic 14-20x test-time speedups while retaining accuracy comparable to the Bi-LSTM-CRF. Moreover, ID-CNNs trained to aggregate context from the entire document are even more accurate while maintaining 8x faster test time speeds.
Effect of a tail piece cysteine deletion on biochemical and functional properties of an epidermal growth factor receptor-directed IgA2 m(1) antibody (2013)

Antibodies of human IgA isotype are critical components of the mucosal immune system, but little is known about their immunotherapeutic potential. Compared with IgG antibodies, IgA molecules carry a C-terminal tail piece extension of 18 amino acids with a free cysteine at position 471. This cysteine is required for the formation of dimeric IgA antibodies, but may impair molecular characteristics of monomeric IgA antibodies as therapeutic reagents. Thus, we generated and characterized a d471-mutated antibody against the epidermal growth factor receptor (EGFR) and compared it to its respective IgA2m(1) wild type antibody. Both wild type and mutated IgA antibodies demonstrated similar EGFR binding and were similarly efficient in inhibiting EGF binding and in blocking EGF-mediated cell proliferation. Recruitment of Fc-mediated effector functions like antibody-dependent cell-mediated cytotoxicity by monocytes, macrophages or PMN was similar, but the d471-mutated IgA exhibited different biochemical properties compared with wild type antibody. As expected, mutated IgA did not form stable dimers in the presence of human joining (J)-chain, but we also observed reduced levels of dimeric aggregates in the absence of J-chain. Furthermore, glycoprofiling revealed different glycosylation patterns for both antibodies, including considerably less mannosylation of d471-mutated antibodies. Overall, our results demonstrate that the deletion of the C-terminal cysteine of IgA2 did not affect the investigated effector functions compared with wild type antibody, but it improved biochemical properties of an IgA2m(1) antibody against EGFR, and may thereby assist in exploring the immunotherapeutic potential of recombinant IgA antibodies.

Development Of Transdermal Patches Of Verapamil Hydrochloride Using Sodium Carboxymethyl Guar As A Monolithic Polymeric Matrix And Their Invitro Release Studies (1997)

An attempt has been made to develop Transdermal patches of Verapamil HCI by using Sodium Carboxymethyl Guar as Polymer matrix, Propylene glycol as the plasticiser and Alupoly foil as the backing membrane. A comparison of various polymers and plasticisers were also made. In vitro release studies through mouse skin have shown that Sodium Carboxymethyl Guar as a suitable polymer. The primary skin irritatancy tests have shown that the transdermal patches are non irritant.
X-ray and Neutron Diffraction Study of Nanocrystalline Ti−Ru−Fe−O Compounds (1998)

The effect of adding oxygen on the structure of nanocrystalline Ti−Ru−Fe compounds obtained by high-energy ball-milling has been studied by X-ray and neutron diffraction using a Rietveld refinement analysis. It is shown that oxygen atoms readily oxidize Ti to form various types of titanium oxides depending on the oxygen content. In each case, a simple cubic structure (cP2-CsCl) is also formed during milling but with a concentration higher than expected on the basis of various reaction schemes. Through a detailed analysis of the neutron and X-ray diffraction peaks, it is shown that the 1a site of the CsCl-type unit cell is depleted from Ti atoms by preferential substitution with Fe. At high oxygen concentration, the alloy is a multiphase material containing Ti2-xRu1+yFe1+z, Ti oxides, Ru, and Fe.
Expanding the Role of the Virome: Commensalism in the Gut (2014)

Viruses affect host physiology beyond causing acute disease, thereby giving rise to the concept that the virome is a component of the microbiome. However, the role of the enteric virome is understudied relative to the fast-paced research examining commensal bacteria in the intestine. In this article, I discuss our recent work on murine norovirus indicating that an animal virus in the intestine can provide many of the signals to the host that have been attributed to commensal bacteria. Our findings suggest that the surge in microbiome research should incorporate examination of the enteric virome.
Named Entity Extraction From Speech (1998)

We report results using a hidden Markov model to extract information from broadcast news. IdentiFinder^TM was trained on the broadcast news corpus and tested on both the 1996 HUB-4 development test data and the 1997 HUB-4 evaluation test data with respect to the named entity (NE) task: extracting . names of locations, persons, and organizations; . dates and times; . monetary amounts and percentages. Evaluation is based on automatic word alignment of the speech recognition output (the NIST algorithm) followed by the MUC6 /MUC-7 scorer for NE on text, since MUC scoring assumes identical text in the system output and in the answer key. Additionally, we used the experimental MITRE scoring metric (Burger, et al., 1998). The most encouraging result is that a language-independent, trainable information extraction algorithm degraded on speech input at most by the word error rate of the recognizer. 1.
