Fear Network Model in Panic Disorder: The Past and the Future (2018)

The core concept for pathophysiology in panic disorder (PD) is the fear network model (FNM). The alterations in FNM might be linked with disturbances in the autonomic nervous system (ANS), which is a common phenomenon in PD. The traditional FNM included the frontal and limbic regions, which were dysregulated in the feedback mechanism for cognitive control of frontal lobe over the primitive response of limbic system. The exaggerated responses of limbic system are also associated with dysregulation in the neurotransmitter system. The neuroimaging studies also corresponded to FNM concept. However, more extended areas of FNM have been discovered in recent imaging studies, such as sensory regions of occipital, parietal cortex and temporal cortex and insula. The insula might integrate the filtered sensory information via thalamus from the visuospatial and other sensory modalities related to occipital, parietal and temporal lobes. In this review article, the traditional and advanced FNM would be discussed. I would also focus on the current evidences of insula, temporal, parietal and occipital lobes in the pathophysiology. In addition, the white matter and functional connectome studies would be reviewed to support the concept of advanced FNM. An emerging dysregulation model of fronto-limbic-insula and temporooccipito-parietal areas might be revealed according to the combined results of recent neuroimaging studies. The future delineation of advanced FNM model can be beneficial from more extensive and advanced studies focusing on the additional sensory regions of occipital, parietal and temporal cortex to confirm the role of advanced FNM in the pathophysiology of PD.

Transmission noise eliminations in BDPCM image (1993)

The image compression possibilities of the BDPCM (blurred differential pulse code modulation) technique, which reduces information and increases correlation with signal blurring , are shown. Under the same quantization steps, signal flow at the coder is analyzed and complete signal reconstruction properties are shown. The dynamic range of the difference values of BDPCM is analyzed with the same quantization steps as conventional DPCM. In order to improve the median filter that reduces impulse noise with blurring, adaptive filtering for the differences is proposed. By means of the difference range, transmission impulse noises are detected and corrected by the filter. Therefore, a low-bit-rate image codec with noise elimination is proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Two-stage Overlap Frequency Domain Equalization for Long-haul Optical Systems (2009)

We propose two-stage overlap frequency domain equalization (OFDE) to compensate chromatic dispersion and polarization mode dispersion in practical long-haul optical systems. This paper evaluates the performance of 25-Gb/s coherent optical single-carrier transmission using two-stage OFDE.
Sequential Deposition: Optimization of Solvent Swelling for High-Performance Polymer Solar Cells (2014)

Organic solar cells based on a typical DPP polymer were systematically optimized by a solvent swelling assisted sequential deposition process. We investigated the influence of solvent swelling on the morphology and structure order of the swollen film and the resultant device performance. Morphological and structural characterization confirmed the realization of ideal bulk heterojunctions using a suitable swelling solvent. A trilayered morphology was also found with the conjugated polymer concentrated bottom layer, PC71BM concentrated top layer, and interpenetrated networks of donor and acceptor in the middle by solvent swelling instead of thermal annealing in the sequential solution processing method. We proposed a simple strategy to optimize the sequential deposition fabricated devices by tuning the concentration of the PC71BM solution instead of thermal annealing. The best device showed a PCE of 7.59% with a Voc of 0.61 V, Jsc of 17.95 mA/cm(2), and FF of 69.6%, which is the highest reported efficiency for devices fabricated by a sequential processing method and among the best results for DPP polymers.
The Management of the Symptomatic Patient with a Metal-on-Metal Hip Prosthesis (2016)

Metal-on-metal (MoM) hip implants have gained popularity due to their greater stability and reduction in implant failure compare to metal-on-polyethylene prostheses. However, as well as carrying general risks of hip implantation, risks specifically associated with MoM implants have been well documented in recent years. Conditions such as pseudotumours or aseptic lymphocyte-dominated vasculitis-associated lesions are specific to MoM hip implants. In this review we discuss the typical patient presentation, the investigations that should be performed, the typical findings on various imaging modalities, and the treatment options of symptomatic patients with MoM hip arthroplasties.
Surface modifications of dental implants (2008)

Dental implant surface technologies have been evolving rapidly to enhance a more rapid bone formation on their surface and hold a potential to increase the predictability of expedited implant therapy. While implant outcomes have become highly predictable, there are sites and conditions that result in elevated implant loss. This paper reviews the impact of macro-retentive features which includes approaches to surface oxide modification, thread design, press-fit and sintered-bead technologies to increase predictability of outcomes. Implant designs that lead to controlled lateral compression of the bone can improve primary stability as long as the stress does not exceed the localized yield strength of the cortical bone. Some implant designs have reduced crestal bone loss by use of multiple cutting threads that are closely spaced, smoothed on the tip but designed to create a hoop-stress stability of the implant as it is completely seated in the osteotomy. Following the placement of the implant, there is a predictable sequence of bone turnover and replacement at the interface that allows the newly formed bone to adapt to microscopic roughness on the implant surface, and on some surfaces, a nanotopography (<10(-9) m scale) that has been shown to preferably influence the formation of bone. Newly emerging studies show that bone cells are exquisitely sensitive to these topographical features and will upregulate the expression of bone related genes for new bone formation when grown on these surfaces. We live in an exciting time of rapid changes in the modalities we can offer patients for tooth replacement therapy. Given this, it is our responsibility to be critical when claims are made, incorporate into our practice what is proven and worthwhile, and to continue to support and provide the best patient care possible.
Deactivation of glass capillary columns by silylation. Part 1: Principles and basic technique (1979)

Abstract A deactivation procedure is described based on a published method using hexamethyldisilazane in the gas phase. In addition to unusually high inertia and thermostability, the method produces truly neutral columns which allow simultaneous analysis of moderately strong free acids and bases. The silylated columns show their full potential only with on‐column injection. Preliminary experimental directions are given; more elaborate directions will become available after extended optimization work.

Synthesis and Use of a New Bromoacetyl-Derivatized Heterotrifunctional Amino Acid for Conjugation of Cyclic RGD-Containing Peptides Derived from Human Bone Sialoprotein (1995)

A new amino acid derivative, N alpha-(tert-butyloxycarbonyl)-N beta-(bromoacetyl)diaminopropionic acid (BBDap), has been synthesized as a reagent for introducing side-chain bromaocetyl groups into any position of a peptide sequence during solid-phase peptide synthesis. By using minor modifications to the protocol of the automated peptide synthesizer and a two-step in situ neutralization procedure, the syntheses of (bromoacetyl)diaminopropionic acid (BDap) in Arg-Gly-Asp-containing peptides from human bone sialoprotein were optimized and completed. Following HPLC purification, the BDap-derivatized peptides were cyclized or/and conjugated to carrier protein or to glass cover slips. In addition, a new procedure for site-specific conjugation of cyclic peptides to protein carriers or to glass was developed. The cell attachment activity of the peptide derivatives and conjugates was tested in cell adhesion assays with human osteoblasts, and the specificity of the binding was confirmed by competition with linear and/or cyclic forms of GRGDS. The results show that conjugates containing the linear and cyclic derivatives of the peptide EPRGDNYR supported cell attachment and spreading in a dose-dependent manner when the peptides were immobilized as described. Cell attachment to the intact bone sialoprotein and to conjugates containing the linear peptides was abolished by competition with linear and cyclic RGD-containing peptides, whereas the attachment to conjugates containing the cyclic peptide was inhibited only partially, and the cell spreading was preserved even in the presence of RGD-peptides.
Multilevel optical networks (2003)

The authors present MONET, a family of multilevel optical networks based on wavelength division multiplexing (WDM). MONET combines features of several existing WDM network architectures. The low level clusters are operated with time and wavelength division, and single-hop communications. These clusters are then interconnected with a multihop backbone. Additional wavelengths are also available on demand for real-time intercluster communications. It is shown that MONET, by combining the features of single- and multihop WDM schemes, can overcome some of their limitations. More precisely, it can support a much larger user population than single-hop schemes and can carry broadcast and real-time traffic more efficiently than multihop schemes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The effect of cross-channel synchrony on the perception of temporal regularity (2005)

Temporal models of pitch are based on the assumption that the auditory system measures the time intervals between neural events, and that pitch corresponds to the most common time interval. The current experiments were designed to test whether time intervals are analyzed independently in each peripheral channel, or whether the time-interval analysis in one channel is affected by synchronous activity in other channels. Regular and irregular click trains were filtered into narrow frequency bands to produce target and flanker stimuli. The threshold for discriminating a regular target from an irregular distracter click train was measured in the presence of an irregular masker click train in the target band, as a function of the frequency separation between the target band and a flanker band. The flanker click train was either regular or irregular. The threshold for detecting the regular target was 5-7 dB lower when the flanker was regular. The data indicate that the detection of temporal regularity (and thus, pitch) involves cross-channel processes that can operate over widely separated channels. Model simulations suggest that these cross-channel processes occur after the time-interval extraction stage and that they depend on the similarity, or consistency, of the time-interval patterns in the relevant channels.

Crohn's disease: emerging pathologic and bacterial spectrum. (1984)

The evolution, in recent years, of concepts of inflammatory bowel disease in part reflect improved methods of defining disease, especially with modern microbiologic methods, endoscopy and mucosal biopsy. Although clinicians have focused on idiopathic ulcerative colitis and Crohn's disease, a host of new entities are now becoming recognized. Many of these are bacterial, such as Yersinia- or Campylobacter-associated enterocolitis. Thus, a "new" group of inflammatory bowel diseases has recently emerged, some with newly described pathologic features and others reflecting improved methods of detection with newer microbiologic methods. With evolving methods of recognition, other entities will likely be described as causes of inflammatory bowel disease.
Modularity concepts of the Multi-Path Redundant Avionics Suite (MPRAS) (2002)

The use of modularity within the Multipath Redundant Avionics Suite project is discussed. Modularity is considered at several levels, including systems, subsystems, electronic circuit assemblies and even functionality within circuit assemblies. MPRAS maintains the modularity of PAVE PILLAR and extends it to include modules designed to provide efficient input/output functions and to support implementation of multistring redundancy. A method of configuring multiple sets of avionics modules (clusters) into a fault-tolerant redundant subsystem has been developed. These subsystems are intended to be incorporated into the overall system in a modular fashion to support vehicles such as the advanced launch system, which are themselves designed as modular vehicle families. The software operating system is also modular, based on the Ada high order language, and can be configured for specific vehicle functions. Deterministic system software operation and high levels of avionics testability provide an environment intended to keep system operations costs as low as possible. The result is an avionics architecture which can be used in a wide variety of applications, from the simplest launch vehicles to complex systems envisioned for future space exploration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Measuring Trace Impurities in Air by Infrared Spectroscopy at 20 Meters Path and 10 Atmospheres Pressure (1974)

Use of a new type of drying device achieves considerable selectivity in the removal of water from ambient air. The sample may then he compressed to 10 atm, without the separation of liquid water that would otherwise occur. Use of this higher pressure in a 20-meter gas cell permits the infrared spectral detection of many compounds of toxicological interest in the 0.05- to 1-ppm range.
A Polymorphism in Thrombospondin-1 Associated with Familial Premature Coronary Artery Disease Alters Ca2+ Binding (2004)

A single nucleotide polymorphism that results in substitution at residue 700 of a serine (Ser-700) for an asparagine (Asn-700) in thrombospondin-1 is associated with familial premature coronary artery disease. The polymorphism is located in the first of 13 Ca2+ -binding motifs, within a consensus sequence in which Asn-700 likely coordinates Ca2+. Equilibrium dialysis of constructs comprised of the adjoining epidermal growth factor-like module and the Ca2+ -binding region (E3Ca) demonstrated that E3Ca Ser-700 binds significantly less Ca2+ than E3Ca Asn-700 at low [Ca2+]. The hypothesis that this difference is due to loss of a binding site in Ser-700 protein was tested with truncations of E3Ca containing four (Tr4), three (Tr3), two (Tr2), or one (Tr1) N-terminal Ca2+ -binding motifs. The Ser-700 truncation constructs bound 1 fewer Ca2+ than matching Asn-700 constructs and exhibited decreased binding affinities. Intrinsic fluorescence of a tryptophan at residue 698 (Trp-698) in the most N-terminal motif was cooperatively quenched by the addition of Ca2+ to Asn-700 Tr2, Tr3, and Tr4 constructs. In Ser-700 constructs, quenching of Trp-698 was incomplete in the Tr2 and Tr3 constructs and complete only in the Tr4 construct. Ca2+ -induced quenching of Ser-700 constructs required higher [Ca2+] and was slower as shown in stopped-flow experiments than quenching of Asn-700 constructs. Such differences were not found with Tb3+, which quenched the fluorescence of Asn-700 and Ser-700 constructs equivalently. Thus, the Ser-700 polymorphism alters a rapidly filled, high affinity Ca2+ -binding site in the first Ca2+ -binding motif. Slower Ca2+ binding to adjoining motifs partly compensates for the change.

Transformerless photovoltaic systems using neutral point clamped multilevel inverters (2010)

In some photovoltaic applications it is possible to remove the transformer of the system in order to reduce losses, cost and size. In transformerless systems the photovoltaic module parasitic capacitance can introduce leakage currents in which the amplitude depends on the converter topology, on the pulse-width-modulation and on the resonant circuit composed by the system components. In this paper a modulation technique for three-phase neutral point clamped multilevel inverters is proposed to eliminate the leakage current in photovoltaic systems without requiring any modification on the multilevel inverter. The neutral point clamped inverter is studied for systems with function of active filter using the p-q theory. The proposed system presents control of the maximum power point and compensation of current harmonics and reactive power.
Reduced response to the formalin test and lowered spinal NMDA glutamate receptor binding in adenosine A2A receptor knockout mice (2006)

Adenosine is a neuromodulator with complex effects on pain pathways. Mice lacking the adenosine A2A receptor are hypoalgesic, and have altered analgesic responses to receptor-selective opioid agonists. These and other findings suggest a role for the adenosine A2A receptor in sensitizing afferent fibres projecting to the spinal cord. To test this hypothesis formalin (20 microl, 5%) was injected into the paw and nociceptive responses were measured in wildtype and adenosine A2A receptor knockout mice. There was a significant reduction in nociception associated with sensory nerve activation in the knockout mice as measured by time spent biting/licking the formalin-injected paw and number of flinches seen during the first phase, but only the number of flinches was reduced during the second inflammatory phase. In addition, the selective adenosine A2A antagonist SCH58261 (3 and 10 mg/kg) also antagonised both phases of the formalin test. We also labelled NMDA glutamate and NK1 receptors in spinal cord sections as an indirect measure of nociceptive transmission from peripheral sites to the spinal cord. [3H]-Substance P binding to NK1 receptors was unaltered but there was a substantial reduction in binding of [3H]-MK801 to NMDA glutamate receptors in all regions of the spinal cord from knockout mice. The decrease in NMDA glutamate receptor binding may reflect reduced peripheral sensory input to the spinal cord during development and could relate to the hypoalgesia in this genotype. These results support a key role for the adenosine A2A receptor in peripheral nociceptive pathways.
Alkyllithium and alkali metal <i>tert</i>‐butoxide as polymerization initiator (1969)

Abstract We have shown that the presence of other alkali metal alkoxides in the alkyllithium‐initiated polymerization drastically increases the rate of polymerization and vinyl unsaturation in polybutadiene. Mechanistically, the propagating center is the dynamic equilibriums between carbon–metal bonds and oxygen–metal bonds. With potassium, rubidium, and cesium salts it reaches a limiting anionic behavior.
Implicit Active Contours Driven by Local Binary Fitting Energy (2007)

Local image information is crucial for accurate segmentation of images with intensity inhomogeneity. However, image information in local region is not embedded in popular region-based active contour models, such as the piecewise constant models. In this paper, we propose a region-based active contour model that is able to utilize image information in local regions. The major contribution of this paper is the introduction of a local binary fitting energy with a kernel function, which enables the extraction of accurate local image information. Therefore, our model can be used to segment images with intensity inhomogeneity, which overcomes the limitation of piecewise constant models. Comparisons with other major region-based models, such as the piece-wise smooth model, show the advantages of our method in terms of computational efficiency and accuracy. In addition, the proposed method has promising application to image denoising.
