Homocysteine and other thiols determined in plasma by HPLC and thiol-specific postcolumn derivatization (1993)

We describe a versatile high-performance liquid-chromatographic method for determining homocysteine and other plasma sulfhydryls. Using three different procedures for preparation of plasma, we determined total, free (non-protein-bound), and reduced forms of homocysteine, cysteine, glutathione, cysteinylglycine, and gamma-glutamylcysteine in human plasma. Sample preparation involves disulfide reduction with dithiothreitol and protein precipitation with sulfosalicylic acid. The assay utilizes isocratic reversed-phase ion-pair liquid chromatography at pH 2.4, postcolumn derivatization with 4,4'-dithiodipyridine, and colorimetric detection at 324 nm. The intra-assay precision (CV) of the method for total homocysteine is 1.5%; the interassay precision over 2.5 months is 2.5%. The detection limit for homocysteine is < 50 nmol/L plasma.
[Intraoperative injuries of the superior laryngeal nerve in thyroid surgery]. (2004)

The intraoperative injury of the external branch of the Superior Laryngeal Nerve (SLN) is a disregarded complication of thyroid surgery that becomes a serious one for particular professional groups. The Authors retrospectively evaluate 124 cases of total thyroidectomies performed by the same surgeon from 1999 to 2002. Clinically evaluated SLN lesions (hypomobility of the vocal cord) was registered in six patients (4.8%). Routine identification of SLN and meticulous dissection of the superior thyroid vessels must be the technical benchmark to avoid nerve injury, even if bulky disease, anatomic variations and previous surgery may increase the chance of nerve damaging.
Novel Low-Molecular-Weight Gelators Based on Azobenzene Containing <scp>l</scp>-Amino Acids (2005)

Abstract A series of azobenzene derivatives containing glycine, l-alanine, l-valine, l-leucine, and l-isoleucine were synthesized and their gelation properties were examined. Although the azobenzene derivatives containing glycine, l-alanine, and l-leucine exhibited very low gelation abilities, other compounds of l-isoleucine and l-valine acted as good gelators that formed organogels in many organic solvents and oils at relatively low concentrations. The electron microscopic observation demonstrated that a three-dimensional network was created by entanglement of self-assembled nanofibers. Furthermore, the spectroscopic studies suggested that the gelator molecules self-assembled into the nanofibers through hydrogen bonding and π–π interactions, including the H-aggregation mode of the azobenzene segments.

Multi-microphone adaptive noise reduction strategies for coordinated stimulation in bilateral cochlear implant devices (2010)

Bilateral cochlear implant (BI-CI) recipients achieve high word recognition scores in quiet listening conditions. Still, there is a substantial drop in speech recognition performance when there is reverberation and more than one interferers. BI-CI users utilize information from just two directional microphones placed on opposite sides of the head in a so-called independent stimulation mode. To enhance the ability of BI-CI users to communicate in noise, the use of two computationally inexpensive multi-microphone adaptive noise reduction strategies exploiting information simultaneously collected by the microphones associated with two behind-the-ear (BTE) processors (one per ear) is proposed. To this end, as many as four microphones are employed (two omni-directional and two directional) in each of the two BTE processors (one per ear). In the proposed two-microphone binaural strategies, all four microphones (two behind each ear) are being used in a coordinated stimulation mode. The hypothesis is that such strategies combine spatial information from all microphones to form a better representation of the target than that made available with only a single input. Speech intelligibility is assessed in BI-CI listeners using IEEE sentences corrupted by up to three steady speech-shaped noise sources. Results indicate that multi-microphone strategies improve speech understanding in single- and multi-noise source scenarios.
허베이스피리트호의 사고로부터 유출된 표착유의 OMA에 의한 제거 (2009)

태안연안에서 표착된 기름의 제거과정을 파악하고 연안 조간대에 표착된 유출유를 자연친화적으로 제거하기 위해서 물리화학적 인자의 변화가 OMA 형성에 미치는 영향을 평가하는 것을 목적으로 하여 연구를 수행하였다.
허베이스피리트호의 기름유출사고로 오염된 태안연안의 구름포와 만리포 해수욕장은 자원봉사자와 지역주민의 방제노력과 표착유와 토립자가 형성한 OMA 그리고 파도의 반복적인 작용이 표착유의 제거에 중요한 역할을 한 것으로 판단된다. 점토광물인 kaolinite가 비점토광물인 quartz에 비해서 OMA의 형성에 약 3배 이상의 효율을 갖고 있는 것으로 판단되며, 점토광물의 함유량이 많은 해안에서의 표착유의 제거가 보다 원활하리라 판단된다. 표착유량이 많을수록 OMA 형성이 증가하였으며, 염분농도는 OMA의 형성에 커다란 영향을 미치지 않는 것으로 파악되었다.
A Low Complexity Algorithm for Proportional Resource Allocation in OFDMA Systems (2004)

Orthogonal frequency division multiple access (OFDMA) basestations allow multiple users to transmit simultaneously on different subcarriers during the same symbol period. This paper considers basestation allocation of subcarriers and power to each user to maximize the sum of user data rates, subject to constraints on total power, bit error rate, and proportionality among user data rates. Previous allocation methods have been iterative nonlinear methods suitable for offline optimization. In the special high subchannel SNR case, an iterative root-finding method has linear-time complexity in the number of users and N log N complexity in the number of subchannels. We propose a non-iterative method that is made possible by our relaxation of strict user rate proportionality constraints. Compared to the root-finding method, the proposed method waives the restriction of high subchannel SNR, has significantly lower complexity, and in simulation, yields higher user data rates.
Transmission of an Uncultivated <i>Bergeyella</i> Strain from the Oral Cavity to Amniotic Fluid in a Case of Preterm Birth (2006)

Intrauterine infection is a recognized cause of preterm birth. The infectious organisms are believed to originate primarily from the vaginal tract and secondarily from other parts of the body. It is plausible that microbes in the oral cavity can be transmitted to the pregnant uterus. However, direct evidence supporting such a transmission is lacking. In this study, amniotic fluids of 34 pregnant women were examined by PCR using 16S and 23S rRNA universally conserved primers. Bacterial DNA was amplified from the only patient with clinical intrauterine infection and histologic necrotizing acute and chronic chorioamnionitis. One strain, Bergeyella sp. clone AF14, was detected and was 99.7% identical to a previously reported uncultivated oral Bergeyella strain, clone AK152, at the 16S rRNA level. The same strain was detected in the subgingival plaque of the patient but not in her vaginal tract. The 16S-23S rRNA sequence of clone AF14 matched exactly with the sequences amplified from the patient's subgingival plaque. These observations suggest that the Bergeyella strain identified in the patient's intrauterine infection originated from the oral cavity. This is the first direct evidence of oral-utero microbial transmission. The patient's periodontal health during pregnancy was unclear. She did not have detectable periodontal disease during postpartum examination. Bergeyella spp. had not been previously associated with preterm birth and were detected in subgingival plaque of women without clinical levels of intrauterine infection. Uncultivated species may be overlooked opportunistic pathogens in preterm birth. This study sheds new light on the implication of oral bacteria in preterm birth.
Psoralen-modified oligonucleotide primers improve detection of mutations by denaturing gradient gel electrophoresis and provide an alternative to GC-clamping (1993)

Denaturing gradient gel electrophoresis (DGGE), a mutation-scanning procedure separating DNA fragments differing by as little as a single base change, is widely used in studies of genomic nucleotide sequence variability. The efficiency of the technique is greatly enhanced by attaching, through polymerase chain reaction (PCR) incorporation, a long GC-tail to the test DNA sequence which, as a result, becomes analysable throughout. As synthesis of GC-rich specific PCR primers is costly and time-consuming, we attempted to clamp the DNA fragment using a psoralen derivative (ChemiClamp) that promotes photo-induced cross-linking at one end. We found that this procedure provides an attractive alternative to GC-clamp in DGGE (and temperature gradient gel electrophoresis) and should prove useful in both research and diagnostic laboratories.
Burkitt lymphoma cell line carrying a variant translocation creates new DNA at the breakpoint and violates the hierarchy of immunoglobulin gene rearrangement. (1985)

The Burkitt lymphoma cell line KK124, which contains a reciprocal t(8;22) translocation, was shown to have rearranged in a region 3' to the c-myc proto-oncogene on chromosome 8 and 5' to the lambda constant region on chromosome 22. The breakpoint was cloned and sequenced, revealing that c-myc and a portion of its 3' region abutted a complete lambda variable gene that had undergone V-J recombination. Since this cell line expresses kappa light chain, this lambda rearrangement violates the previously proposed hierarchy of immunoglobulin gene rearrangement. A novel duplication of normal chromosome 8 sequences was also found at the breakpoint. The first exon of c-myc and its flanking sequence from the translocated allele was sequenced and compared with a normal counterpart. Extensive mutation was found within the first exon in contrast to its 3' and 5' flanking regions. S1 nuclease analysis revealed that it was the translocated c-myc being expressed and that there was a promoter shift from P2 to P1. The detailed structural analysis of this cell line provides clues concerning mechanisms of chromosomal translocation and c-myc deregulation in Burkitt lymphomas.
Human serum IgE‐mediated mast cell degranulation shows poor correlation to allergen‐specific IgE content (2003)

Our studies demonstrate that mast cell activation mediated through IgE from allergic patients is a result of complex relationships that are not only dependent on allergen-specific IgE content but also relate to the capacity to efficiently sensitize and trigger the signalling responses that lead to degranulation.
A Mitogen-Activated Protein Kinase Cascade in the CA1/CA2 Subfield of the Dorsal Hippocampus Is Essential for Long-Term Spatial Memory (1999)

Behavioral, biophysical, and pharmacological studies have implicated the hippocampus in the formation and storage of spatial memory. However, the molecular mechanisms underlying long-term spatial memory are poorly understood. In this study, we show that mitogen-activated protein kinase (MAPK, also called ERK) is activated in the dorsal, but not the ventral, hippocampus of rats after training in a spatial memory task, the Morris water maze. The activation was expressed as enhanced phosphorylation of MAPK in the pyramidal neurons of the CA1/CA2 subfield. In contrast, no increase in the percentage of phospho-MAPK-positive cells was detected in either the CA3 subfield or the dentate gyrus. The enhanced phosphorylation was observed only after multiple training trials but not after a single trial or after multiple trials in which the location of the target platform was randomly changed between each trial. Inhibition of the MAPK/ERK cascade in dorsal hippocampi did not impair acquisition, but blocked the formation of long-term spatial memory. In contrast, intrahippocampal infusion of SB203580, a specific inhibitor of the stress-activated MAPK (p38 MAPK), did not interfere with memory storage. These results demonstrate a MAPK-mediated cellular event in the CA1/CA2 subfields of the dorsal hippocampus that is critical for long-term spatial memory.
Neural networks for switching (1989)

The author argues that a strong impetus for using neural networks is that they provide a framework for designing massively parallel machines. He notes that the highly interconnected architecture of switching networks suggests similarities to neural networks. He presents two switching applications in which neural networks can solve the problems efficiently. He shows that a computational advantage can be gained by using nonuniform time delays in the network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Augmented reality system for MR-guided interventions: phantom studies and first animal test (2004)

We developed an augmented reality navigation system for MR-guided interventions. A head-mounted display provides in real-time a stereoscopic video-view of the patient, which is augmented with three-dimensional medical information to perform MR-guided needle placement procedures. Besides with the MR image information, we augment the scene with 3D graphics representing a forward extension of the needle and the needle itself. During insertion, the needle can be observed virtually at its actual location in real-time, supporting the interventional procedure in an efficient and intuitive way. In this paper we report on quantitative results of AR guided needle placement procedures on gel phantoms with embedded targets of 12mm and 6mm diameter; we furthermore evaluate our first animal experiment involving needle insertion into deep lying anatomical structures of a pig.
The Case of Baby Andrew (1984)

Who says that the most important and perplexing human dilemmas do not arise in the context of administrative law?ConsiderThe Case of Baby Andrew* One month after the premature birth of her son Andrew, Peggy Stinson wrote in her journal: What threatened to be a simple, private sorrow has changed unexpectedly into something so altogether different, so altogether complicated that thoughts and feelings tangle hopelessly and give no guidance.Andrew is not our baby anymorehe's been taken over by a medical bureaucracy.The bureaucracy controls Andrew -access to Andrew, information about Andrew, decisions about what will happen to Andrew.It rolls inexorably onward, oblivious to our attempts to communicate, participate; oblivious equally to angry reaction and attempts to reconcile.If this sounds bad, it's not half so bad as it will be if President Reagan gets his way.The Stinsons' problem was that they had doctors who followed a rigid ethic of preserving life at virtually any cost, and they could not get their son out of the hands of their doctors.Now, however, the president who promised to cut back on the intrusion of big government into the private lives of American citizens is taking steps to ensure that even when parents, doctors, and a hospital "Infant Care Review Committee" agree on the best course of action for an infant born severely

Models for Frequency-Hopped Spread-Spectrum Communications over Fading Channels. (1982)

The system consisting of the series connection of a frequency-hopper, channel, and frequency-dehopper is modeled as a fading channel. The effect of a detuning factor between the hopping patterns of the hopper and dehopper is investigated. Both slow-frequency-hopped and fast-frequency-hopped systems are studied for cases when the fading channel is nonselective and selective. The ability of the frequency-hopped system to overcome frequency-selective fading is considered. Limits are found on the spacing between frequency slots in order that the fading in different slots is independent. (Author)
Quantitative myelin imaging with coherent anti-Stokes Raman scattering microscopy: alleviating the excitation polarization dependence with circularly polarized laser beams (2009)

The use of coherent anti-Stokes Raman scattering microscopy tuned to the lipid vibration for quantitative myelin imaging suffers from the excitation polarization dependence of this third-order nonlinear optical effect. The contrast obtained depends on the orientation of the myelin membrane, which in turn affects the morphometric parameters that can be extracted with image analysis. We show how circularly polarized laser beams can be used to avoid this complication, leading to images free of excitation polarization dependence. The technique promises to be optimal for in vivo imaging and the resulting images can be used for coherent anti-Stokes Raman scattering optical histology on native state tissue.
Safety benefits of arc-resistant metalclad medium-voltage switchgear (1995)

One cause of serious injuries to electrical workers in the petrochemical industry is flash burns from arcing faults in medium-voltage metalclad switchgear. First introduced in Europe, arc-resistant switchgear designs are now being marketed in North America to eliminate this potential cause of injuries by containing the arc by-products and venting the gases in a safe manner. This paper discusses worker safety regulations, the arcing fault process, standards governing arc-resistant switchgear, and switchgear design, application, and cost/benefit considerations. One manufacturer's experience testing a new arc-resistant switchgear design is included.

Minus-Lens–Stimulated Accommodative Amplitude Decreases Sigmoidally with Age: A Study of Objectively Measured Accommodative Amplitudes from Age 3 (2008)

These data indicate that accommodative amplitude decreases in a curvilinear manner from 3 to 40 years. When combined with data from previous studies, a sigmoidal function describes the overall trend throughout life with the biggest decrease occurring between 20 and 50 years.
Linear versus branched poly-lysine/arginine as polarity enhancer tags (2014)

The design and synthesis of Lys- and Arg-containing peptides as solubilizing tags were studied to evaluate their influence on polarity. The relevance of spatial arrangement of polar groups, in α- or ε-amino positions, was confirmed by chromatographic analysis of a rational PolyLys-based synthesized structure. The most promising of the solubilizing tags here analyzed was conjugated to a commercial water-insoluble drug (indomethacin) as proof of concept.
Parasites of domestic and wild animals in South Africa. XXV. Ixodid ticks on sheep in the north-eastern Orange Free State and in the eastern Cape Province. (1991)

The tick burdens of 115 Merino sheep, slaughtered over a period of 15 consecutive months on a farm in the north-eastern Orange Free State, were determined. A total of 7 ixodid and 1 argasid tick species were recovered and the seasonal abundances of Boophilus decoloratus, Hyalomma marginatum rufipes, Margaropus winthemi and Rhipicephalus evertsi evertsi were determined. One hundred and forty-nine Merino sheep were slaughtered over periods varying from 10 to 25 months on 3 farms in Eastern Province Thornveld in the eastern Cape Province and their tick burdens determined. Fourteen ixodid tick species were recovered from these animals and the seasonal abundances of Amblyomma marmoreum, B. decoloratus, Haemaphysalis silacea, R. evertsi evertsi and Rhipicephalus nitens were ascertained. On a farm in Valley Bushveld in the eastern Cape Province, 2 Dorper sheep were slaughtered each month for a period of 24 consecutive months. These 48 sheep harboured 10 ixodid tick species and the seasonal abundances of A. marmoreum, H. silacea, Rhipicephalus appendiculatus and Rhipicephalus glabroscutatum were determined. A total of 17 ixodid tick species, of which 12 had reached the adult stage, where recovered from the sheep on the 5 farms.
Electrocatalytic Hydrogen Production by an Aluminum(III) Complex: Ligand‐Based Proton and Electron Transfer (2015)

Abstract Environmentally sustainable hydrogen‐evolving electrocatalysts are key in a renewable fuel economy, and ligand‐based proton and electron transfer could circumvent the need for precious metal ions in electrocatalytic H 2 production. Herein, we show that electrocatalytic generation of H 2 by a redox‐active ligand complex of Al 3+ occurs at −1.16 V vs. SCE (500 mV overpotential).
