Direct correlation of single particle motion to amorphous microstructural components of semicrystalline poly(ethylene oxide) electrolytic films (2020)

Semicrystalline polymers are an ubiquitous class of materials incorporated into everyday life, and their functional properties are contingent on their structure over a hierarchical range of length scales. By correlating micro- and nano- structural crystalline and amorphous components of lithium triflate doped PEO thin films with fluorescent single particle trajectories, we find that crystalline fibers anisotropically constrain probe transport without altering the intrinsic diffusivity of probes. Our findings suggest controlled and periodic arrangement of crystalline fibers is a promising design principle for mass transport in semicrystalline polymers that enables the requisite mechanical stability for device applications.
Descending Necrotizing Mediastinitis: A Modified Algorithmic Approach To Define a New Standard of Care (2013)

We applied an algorithmic approach to the treatment of DNM, consisting of aggressive operative debridement and enhanced by equally aggressive imaging. Our patients had excellent outcomes despite the widely known lethality of DNM. An aggressive approach may decrease complications and improve survival in this devastating disease process. Furthermore, our prospective experience with DNM suggests that this algorithm used in the present study should be the standard for managing patients with this challenging condition.
Ovarian Sertoli-Leydig cell tumor in an amenorrheic hirsute patient. (1996)

As ovarian Sertoli-Leydig cell tumors are extremely rare, it appears worthwhile to report cases with uncommon clinical and/or laboratory findings. A 37-year-old nulligravida female was referred because of secondary amenorrhea and hirsutism for 11 years. She appeared virilized with a male body habitus. The highest plasma testosterone (T) level was 1,070 ng/dl. A laparotomy with salpingo-oophorectomy was performed and the pathological report confirmed the presence of Sertoli-Leydig cell tumor of intermediate differentiation. Ovarian venous T value was 5,690 ng/dl. The patient was alive and well with improved hirsutism 4 years after the operation. The duration of symptoms and T level in our patient were among the highest values ever recorded in the literature. This supports the slowly progressive nature of the tumor and emphasizes that Sertoli-Leydig cell tumors should be included in the differential diagnosis of patients with elevated T level regardless of the duration of clinical symptoms.
The Drug Ontology Project for Elsevier - An RDF Architecture Enabling Thesaurus-Driven Data Integration. (2004)

The DOPE project (Drug Ontology Project for Elsevier) is driven by the need to access multiple information sources through a single interface. In this paper, we describe how DOPE allows thesaurus-driven access to heterogeneous and distributed data, based on the RDF data model. The architecture allows for the easy addition of thesauri and data sources, and can facilitate explorations in ontology mapping and data integration.
SAR object classification using the DAE with a modified triplet restriction (2019)

Although deep learning methods have made great progress in synthetic aperture radar (SAR)‐based remote sensing, lack of training data has often been the major obstacle while they are adopted for SAR automatic target recognition. In this study, a new deep network in the form of a restricted three‐branch denoising auto‐encoder (DAE) is proposed to take the full advantage of limited training samples. In this model, a modified triplet restriction that combines the semi‐hard triplet loss with the intra‐class distance penalty is devised to learn discriminative features with a small intra‐class divergence and a large inter‐class divergence. Besides, the reconstruction distortion is measured between the model outputs and the images filtered by the improved Lee Sigma filter rather than the original inputs to suppress clutter in the background. Furthermore, a batch‐based triplet loss, which calculates the modified triplet loss in a batch‐based manner, is proposed to tackle the difficulties in implementation and reduce its computation complexity. The simplified version of the three‐branch Triplet‐DAE is subsequently devised as a one‐branch DAE restricted by the batch‐based triplet loss. Experimental results with the MSTAR data demonstrate the effectiveness of the proposed method on real SAR images.
Localization of Immunogenic Antigens on Midgut of the Human Body Louse Pediculus humanus humanus (Anoplura: Pediculidae) (1996)

Immunogenic midgut antigens of the human body louse, Pediculus humanus humanus L., were localized using rabbit antisera against a louse-midgut extract followed by a 2nd antibody conjugated to either fluorescein or colloidal gold. Strong fluorescence was observed on the outer membrane of the epithelial cell of the midgut. The immunogold technique revealed that most of the antigens were localized on the microvilli of the midgut cells. Small numbers of gold particles were also seen in the gut lumen and within the cell cytoplasm. Only a few gold particles were seen in the lumen of the gut sections incubated with control sera.

Design of switched-capacitor FIR filters with application to a low-power MFSK receiver (1992)

Finite impulse response (FIR) switched-capacitor (SC) filters for minimum frequency-shift keying (MFSK) demodulation techniques have been developed and are discussed. The proposed filters comprise combinations of the following building blocks: sample-and-hold circuits, even-odd delay circuits, Gillingham delay circuits, recharge memory elements, Lee-Martin summer circuits, recharge summer circuits, and rotator switches. These are described in the paper. Furthermore, composite SC filter structures are derived using a morphological approach. The FIR SC filter structures are compared and evaluated with respect to the required chip area when implemented in 3 μm CMOS technology, and, by computer simulation, with regard to bit error probability when used in an MFSK receiver. It is shown that the receiver performance is independent of the FIR filter structure used. Furthermore, using the FIR filters, and for a given bit error probability, the required signal-to-noise ratio (SNR) is actually 3 dB lower than for a typical commercial MFSK receiver (e.g. an MB87002).
Brønsted acidic ionic liquid catalyzed an efficient and eco-friendly protocol for the synthesis of 2,4,5-trisubstituted-1H-imidazoles under solvent-free conditions (2013)

A simple, highly efficient and eco-friendly protocol for the synthesis of 2,4,5-trisubstituted-1H-imidazoles via one-pot three component condensation of benzil/benzoin, aldehydes and ammonium acetate under solvent-free conditions has been achieved utilizing Brønsted acidic ionic liquid, (4-sulfobutyl)tris(4-sulfophenyl) phosphonium hydrogen sulfate as catalyst. The remarkable features of this methodology are excellent yields in shorter reaction times, cleaner reaction profile, and environmentally benign nature, use of non-toxic, readily synthesizable, inexpensive and recyclable catalyst.
Stereoregulation in cationic polymerization. III. High isospecificity with the bulky phosphoric acid [(RO)2PO2H]/SnCl4 initiating systems: Design of counteranions via initiators (2001)

In the cationic polymerization of isobutyl vinyl ether (IBVE) with binary initiating systems consisting of a protonic acid as an initiator and a Lewis acid as an activator/catalyst, phosphoric acid derivatives [(RO)2POOH] coupled with SnCl4 gave highly isotactic poly(IBVE)s, whereas those with a bulky substituent (R), [C4H9CH(C2H5)CH2O]2POOH (7) and (n-C10H21)2POOH (8), led to the highest isotacticity [meso dyad (m) = 86%]. In contrast, isospecificity was lower with IBVE–HCl and CF3COOH under the same conditions. From the effects of the polymerization temperature (−78 to 0 °C), it was concluded that the high isospecificity with 7 and 8 was due to an enthalpic factor. © 2001 John Wiley & Sons, Inc.

A Monophosphine Ligand Derived from Anthracene Photodimer: Synthetic Applications for Palladium-Catalyzed Coupling Reactions (2019)

Herein, we present an air-stable dianthracenyl monophosphine ligand (diAnthPhos) which can be prepared in two steps from commercially available anthracene derivatives. The ligand exhibits excellent efficiency for palladium-catalyzed coupling reactions. In particular, Miyaura borylation of heterocycle-containing electrophiles can be facilitated employing the diAnthPhos ligand with a broad substrate scope and low catalyst loading. The valuable synthetic utility of the new ligand is further demonstrated by a one-pot Miyaura borylation/Suzuki coupling protocol for heteroaryl-containing substrates.
Nucleotide sequence, transcription map, and mutation analysis of the 13q14 chromosomal region deleted in B-cell chronic lymphocytic leukemia (2001)

Deletions of the 13q14 chromosome region are associated with B-cell chronic lymphocytic leukemia (B-CLL) and several other types of cancer, suggesting the presence of a tumor suppressor gene. In previous studies the minimal region of deletion (MDR) was mapped to a less than 300-kilobase (kb) interval bordered by the markers 173a12-82 and 138G4/1.3R. For the identification of the putative tumor suppressor gene, the entire MDR (approximately 347 kb) has been sequenced, and transcribed regions have been identified by exon trapping, EST-based full-length complementary DNA cloning, database homology searches, and computer-assisted gene prediction analyses. The MDR contains 2 pseudogenes and 3 transcribed genes: CAR, encoding a putative RING-finger containing protein; 1B4/Leu2, generating noncoding transcripts; and EST70/Leu1, probably representing another noncoding gene (longest open reading frame of 78 codons). These genes have been sequenced in 20 B-CLL cases with 13q14 hemizygous deletion, and no mutations were found. Moreover, no somatic variants were found in the entire MDR analyzed for nucleotide substitutions by a combination of direct sequencing and fluorescence-assisted mismatch analysis in 5 B-CLL cases displaying 13q14-monoallelic deletion. The nondeleted allele of the CAR and EST70/Leu1 genes was expressed in B-CLL specimens, including those with monoallelic loss, whereas no expression of 1B4/Leu2 was detectable in B-CLL, regardless of the 13q14 status. These results indicate that allelic loss and mutation of a gene within the MDR is an unlikely pathogenetic mechanism for B-CLL. However, haplo-insufficiency of one of the identified genes may contribute to tumorigenesis. (Blood. 2001;97:2098-2104)
Observations of aerosol by the HALOE Experiment onboard UARS: A preliminary validation (1993)

The HALOE experiment measures vertical profiles of aerosol extinction at five infrared wavelengths. Four of these observations are obtained using a combination of gas filter and broadband radiometer measurements in bands of HF, HCl, CH 4 , and NO centered at wavelengths of 2.45, 3.40, 3.45, and 5.26 μm, respectively. The fifth is obtained using broadband radiometer measurements of CO 2 transmission at 2.79 μm. Error analysis shows that the random extinction uncertainties are generally less than 10% in the aerosol layer, increasing to over 20% at the profile tops. HALOE spectral extinction measurements are shown to be consistent with predicted spectral extinction for stratospheric sulfate aerosol. Profile comparisons between HALOE and independent sources result in generally good agreement in the shape and magnitude of peak extinction and the altitude where the peak extinction occurs. In addition, global aerosol distributions obtained from the data are consistent with expected aerosol morphology. Although the validation is preliminary, the HALOE aerosol data appear to be of excellent quality and to accurately represent optical characteristics and distribution of the aerosols.

아토피피부염에서 임상적 중증도에 따른 알레르기 검사소견 (2006)

Background: The serum levels of serum total IgE, peripheral eosinophils and eosinophil cationic protein (ECP) are known to be elevated in patients with atopic dermatitis. However, the relationship between these laboratory findings and the clinical severity of atolpic dermatitis is controversial. Objective: The purpose of this study was to evaluate serum total IgE, peripheral eosinophil counts, ECP as severity indices or disease markers of atopic dermatitis in Korea. Methods: One hundred and thirty patients were evaluated for the symptoms and signs of atopic dermatitis, and classified into a mild, moderate or severe group according to the clinical severity. We measured for total serum IgE, peripheral eosinophil counts, ECP and assessed allergen-specific IgE using multiple allergosorbent test-chemiluminescent assay (MAST-CLA) and CAP-fluoroenzyme immunoassay (CAP-FEIA). Results: Serum total IgE and peripheral eosinophil counts of patients with atopic dermatitis showed a statistically significant correlation with the clinical severity (p＜0.05). Patients from the severe atopic dermatitis group revealed significantly higher ECP level than those in the mild or moderate group (p＜0.05). The most common inhalant allergen was D. farinae, followed by D. pteronyssinus, housedust, and the most common food allergen was wheat, followed by soyabean and egg white. Conclusion: Total serum IgE, peripheral eosinophils and eosinophil cationic protein (ECP) were good indices reflecting the severity of atopic dermatitis. (Korean J Dermatol 2006;44(9):1051~1057)
Effect of IGF-I on Hair Growth Is Related to the Anti-Apoptotic Effect of IGF-I and Up-Regulation of PDGF-A and PDGF-B (2012)

The effect of IGF-I on hair growth appears to be related to the upregulation of PDGF-A and PDGF-B and to the anti-apoptotic effect of IGF-I.
Entire-domain polynomial approximation of volume currents in the analysis of dielectric scatterers (1995)

A method is proposed for the analysis of electrically medium-sized scatterers made of inhomogeneous, imperfect dielectric. The scatterer is modelled by parallelepipeds of arbitrary shapes and sizes, that can be positioned and interconnected arbitrarily, which enables efficient approximation of very diverse scatterer shapes. The current-density vector is approximated by entire-domain three-dimensional polynomials of arbitrary degree with complex coefficients within individual parallelepipeds, even if the dielectric inside them is continuously inhomogeneous. The coefficients are determined by the point-matching solution of the integral equation for the total current-density vector inside the scatterer. Agreement between the results obtained by the proposed method and those from other sources is found to be excellent, both in the far-field and current distribution. When compared with other available methods, however, the proposed method requires much less unknowns per lambdain diel3, although it is neither conceptually nor computationally more complicated than any of them.
Outsourcing of Academic Clinical Laboratories (2018)

American hospitals are increasingly turning to service outsourcing to reduce costs, including laboratory services. Studies of this practice have largely focused on nonacademic medical centers. In contrast, academic medical centers have unique practice environments and unique mission considerations. We sought to elucidate and analyze clinical laboratory outsourcing experiences in US academic medical centers. Seventeen chairs of pathology with relevant experience were willing to participate in in-depth interviews about their experiences. Anticipated financial benefits from joint venture arrangements often eroded after the initial years of the agreement, due to increased test pricing, management fees, duplication of services in support of inpatients, and lack of incentive for utilization control on the part of the for-profit partner. Outsourcing can preclude development of lucrative outreach programs; such programs were successfully launched in several cases after joint ventures were either avoided or terminated. Common complaints included poor test turnaround time and problems with test quality (especially in molecular pathology, microbiology, and flow cytometry), leading to clinician dissatisfaction. Joint ventures adversely affected retention of academically oriented clinical pathology faculty, with adverse effects on research and education, which further exacerbated clinician dissatisfaction due to lack of available consultative expertise. Resident education in pathology and in other disciplines (especially infectious disease) suffered both from lack of on-site laboratory capabilities and from lack of teaching faculty. Most joint ventures were initiated with little or no input from pathology leadership, and input from pathology leadership was seen to have been critical in those cases where such arrangements were declined or terminated.
Modulation of the growth of transformed cells by human tumor necrosis factor-alpha and interferon-gamma. (1987)

Recombinant human tumor necrosis factor-alpha (rHuTNF-alpha) inhibited growth of the cervical carcinoma cell line, ME-180neo, at doses greater than 50 units/ml, but stimulated the growth of these cells at low doses (0.1-10 units/ml). ME-180neo variants selected for resistance to the cytotoxic effects of rHuTNF-alpha retained the ability to be growth stimulated at all concentrations tested. ME-180neo cells and the rHuTNF-alpha-resistant ME-180neo variants possessed equivalent steady state numbers of TNF-alpha receptors with similar Kd values. Recombinant human interferon-gamma (rHuIFN-gamma) augmented the rHuTNF-alpha-induced cytotoxic response of ME-180neo cells and overcame the resistance of the ME-180neo variants to rHuTNF-alpha cytotoxicity. In separate experiments we were able to show that the number of TNF-alpha binding sites on both rHuTNF-alpha-sensitive and -resistant ME-180neo cells was similar and was increased by treatment with rHuIFN-gamma. These results suggest that the growth stimulation of tumor cells mediated by rHuTNF-alpha can be dissociated from the cytotoxic response and that these responses are not related to the number or affinity of TNF-alpha binding sites.
Underactuated Spacecraft Switching Law for Two Reaction Wheels and Constant Angular Momentum (2016)

This paper develops a switching feedback controller for the attitude of an underactuated spacecraft that exploits two internal control torques provided by reaction wheels. The problem is challenging; for example, even in the zero total angular momentum case, no smooth or even continuous time-invariant feedback law for stabilizing a desired orientation exists. The method introduced here exploits the separation of the system states into inner-loop base variables and outer-loop fiber variables. The base variables track periodic reference trajectories, the amplitude of which is governed by parameters that are adjusted to induce an appropriate change in the fiber variables. Under suitable assumptions on the total angular momentum, this controller stabilizes an equilibrium that corresponds to a desired inertially fixed orientation. If the desired attitude violates the assumption on angular momentum, then controlled oscillations in a neighborhood around the target orientation are induced by the switching controller. The control scheme is based on several approximations and is designed for relatively small maneuvers close to the desired attitude in a vicinity which may be achieved by thruster-based control schemes. Simulation results demonstrate that the switching feedback law provides good performance in controlling the attitude of an underactuated spacecraft.
A Data-Adaptive Compressed Sensing Approach to Polarimetric SAR Tomography of Forested Areas (2012)

Super-resolution imaging via compressed sensing (CS)-based spectral estimators has been recently introduced to synthetic aperture radar (SAR) tomography. In the case of partial scatterers, the mainstream has so far been twofold, in that the tomographic reconstruction is conducted by either directly working with multiple looks and/or polarimetric channels or by exploiting the corresponding single-channel second-order statistics. In this letter, we unify these two methodologies in the context of covariance fitting. In essence, we exploit the fact that both vertical structures and the unknown polarimetric signatures can be approximated in a low-dimensional subspace. For this purpose, we make use of a wavelet basis in order to sparsely represent vertical structures. Additionally, we synthesize a data-adaptive orthonormal basis that spans the space of polarimetric signatures. Finally, we validate this approach by using fully polarimetric L-band data acquired by the E-SAR sensor of the German Aerospace Center (DLR).

Powdery mildew responsive genes of resistant grapevine cultivar 'Regent' (2017)

The ascomycete Erysiphe necator causes powdery mildew disease of grapevine, a disastrous infection which is commonly defeated with multiple fungicide applications in viticulture. Breeding for natural resistance of quality grapes (Vitis vinifera) is thus a major aim of current efforts. The cultivar 'Regent' is resistant to powdery mildew due to an introgression from an American Vitis sp. resistance donor. To identify key regulatory elements in defense responses of 'Regent' we performed transcript analyses after challenging with E. necator inoculation in comparison with a susceptible grapevine. A set of genes selected from preliminary microarray hybridization results were investigated by RT-qPCR. The data indicate an important role of transcription factors MYB15, WRKY75, WRKY33, WRKY7, ethylene responsive transcription factors ERF2 and ERF5 as well as a CZF1/ZFAR transcripton factor in regulating the early defense when the fungus starts the interaction with its host by the formation of haustoria.
