A human dopamine transporter cDNA predicts reduced glycosylation, displays a novel repetitive element and provides racially-dimorphic TaqI RFLPs.

Abstract We describe a cDNA for the human dopamine transporter, which has been implicated in several human disorders linked to dopaminergic function. The cDNA predicts reduced glycosylation of the protein with respect to the rat transporter, as well as a novel repetitive element in the 3′ untranslated region of the cDNA. A TaqI RFLP is also reported that shows a race-specific difference in allelic frequencies.

Il en vient a la conclusion qu’il n’y a pas de verbes a montee ou de controle ambigus, que les aspectuels constituent une classe de verbes homogene, mais que certains emplois de pouvoir, devoir, promettre et menacer entrainent une distinction homonymique.
Dealing with active oxygen intermediates: A halophilic perspective

Although oxygen tensions in the halophilic environment are diminished, they are nevertheless sufficient for the generation of active oxygen intermediates as byproducts of metabolism. Therefore, like all other aerobes, halophilic bacteria are compelled to possess the means to detoxify potentially lethal active oxygen intermediates. This review examines the superoxide, hydrogen peroxide, hydroxyl radical and singlet oxygen scavenging capacity of the halophiles,Halobacterium spp. Specifically, it looks at the potential of the bacteria to generate active oxygen intermediates and then examines the roles of superoxide dismutase, catalase, peroxidase and catalase-peroxidase. It also looks at some non-enzymatic means of neutralizing potentially lethal active oxygen intermediates.
Experimental management by nonoperative adrenergic stimulation of simulated common duct stones.

The effects of β-receptor stimulation by isoproterenol on ampullary flow and passage of intracholedochal foreign bodies were evaluated in dogs. Flow rates for saline across the ampulla were unchanged by β stimulation except for the earlier appearance of flow in association with a decrease in sphincteric resistance. The mean irrigation pressures required for the passage of a foreign body into the duodenum decreased by 46% from control values when isoproterenol was infused. Stimulation of β receptors may thus serve as a valuable adjunct in the management of patients with retained choledochal calculi by decreasing ampullary resistance. The ineffectiveness and hazards of previously utilized agents is discussed.
Pathology tickler: an HL7 monitoring system to provide clinical feedback

The purpose of this project is to develop a software system to provide feedback to radiologists and other clinicians from interventional procedures in which they participate. Using Health Level Seven (HL7) traffic between the anatomy/pathology information system and other major information systems, we were able to develop a semi-automatic 'tickler' system that can notify clinicians of pathology results as well as the absence of pathology results after a specified time interval. By using this system, radiologists can get more rapid feedback concerning their interpretations and thereby learn to distinguish false positive from true positive cases. Potentially, fewer patients would fall through the follow-up cracks when using our system versus a paper-based method. The system demonstrates, among other things, how HL7 information can be a powerful tool at an institution when used for purposes for which it was not intentionally designed.
A hybrid-iterative method for scattering problems

A new technique, named a hybrid-iterative method (HIM), is presented to solve the magnetic field integral equation (MFIE) for the induced currents on an arbitrary, perfectly conducting scatter. The technique is an evolution from two previous techniques developed earlier. The first of the previous techniques used the moment method (MM) to compute correction currents to an optics-type current. The second of the previous techniques effected a significant improvement by eliminating the use of the moment method to obtain the correction currents, using iteration to obtain them. The technique described here incorporates the edge diffraction theory and the Fock theory into the Ansatz of the iterative scheme. This procedure speeds up the algorithm as well as extending the range of problems that can be solved by the iterative scheme. Furthermore, the present technique incorporates the correction currents into the total currents thereby simplifying the iterative scheme. For intermediate size and larger bodies, the central processing unit (CPU) time is significantly less than that of the moment method. Results are presented for a variety of curved and edged two-dimensional cylinders illuminated by a transverse electric plane wave.
Imaging appearances of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia

Abstract Objective The objective of the study was to describe the imaging appearances of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) on computed tomography (CT). Materials and methods Electronic medical records were searched for patients with pathology-proven DIPNECH who had a CT available for review. Eleven patients were included. Results The most common finding on CT was small pulmonary nodules which were present in all patients and were multiple (≥ 5) in 7/11 patients. Other CT findings included mosaic pattern attenuation and bronchial wall thickening/bronchiectasis. Conclusion DIPNECH should be considered as a diagnostic possibility when multiple small pulmonary nodules are identified on CT, particularly if there is an associated carcinoid tumor.

Optically produced true-time delays for phased antenna arrays

A device is described for generating true-time delays optically for microwave signals used in beam steering and beam shaping in phased-array antennas. The device can be adapted to provide delays from picoseconds to nanoseconds. A single, compact unit should provide parallel delays for more than 64 independent antenna elements with a greater than 6-bit resolution. The time delays are produced by multiple reflections in a mirror configuration with continuous refocusing. A single spatial light modulator selects independent optical path lengths for each of the parallel antenna elements. Amplitude control for beam shaping can be integrated into the device. The unit can be made rugged for harsh environments by use of solid-block construction. The operation of the true-time delay device is described, along with the overall system configuration. Preliminary experimental data are given.
Effect of topical corticosteroid on the microbial flora of human skin

The effect of topical triamicinolone acetonide in petrolatum was studied on the microbial flora of forearms unoccluded and occluded with layers of plastic (Saran) wrap. No significant difference between test and petrolatum sites were found at both occluded and unoccluded sites. These observations and their relation to the clinical use of topical corticosteroids are discussed.
The rate elasticity of Florida tourist development (aka bed) taxes.

One aspect of taxation in Florida is unique in that state policymakers have created several different tourist development taxes, generally allowing local governments to adopt up to four of these ad valorem levies (which can total 5%) on transient rentals. The rentals include, but are not limited to, hotel stays. In this article, we estimate the elasticity of this local tax base with respect to the rate for Florida counties with rate changes between 1998 and 2012. Results indicate several significant and large short-term declines from periodic county-level increases in the tax rate, but no significant long-term effects.
Synthesis and Characterization of Novel Bi- and Tricyclic α-Amino Acids

Abstract As part of a medicinal chemistry collaboration, a number of novel bi- and tricyclic α-amino acids were prepared through various routes and characterized by 1H nuclear Overhauser effect difference experiments. The syntheses provide a number of routes to access some highly substituted amino acid derivatives that have not been reported previously. It is envisaged that the chemistry described here could be applied to the synthesis of other unique substrates.
Central nervous system complications in liver transplant recipients--incidence, timing, and long-term follow-up.

Background Neurological impairment is a major source of morbidity and mortality following orthotopic liver transplantation (OLT). We reviewed our experience with neurologic complications among our first 463 consecutive adult OLT recipients. Methods Between September 1988 and October 1993, 463 adult patients underwent OLT. Data on incidence, time of onset, and outcome of central nervous system (CNS) complications was obtained from patient charts, including autopsy results when available. CNS complications were classified by clinical presentation and by etiology. Results 93 patients (20.1%) had CNS complications following OLT. Encephalopathy (11.8%) and seizure (8.2%) were the leading complications. The incidence of immunosuppressive drug-related complications was 5.6%; coma, 1.7%; cerebral hemorrhage, 1.5%; central pontine myelinolysis (CPM), 1.2%; stroke, 0.6%; and primary CNS lymphoma, 0.2%. Most CNS events (80%) were encountered in the first month after OLT. In the majority of cases, encephalopathy (70%) and seizure (50%) presented in the first 2 wk. Although most CNS infections occurred early, 2 patients developed tuberculous meningitis more than 1 yr post-OLT. In 12 patients, death was directly related to CNS complications (2.6%). Conclusions Most CNS complications occur early following OLT but may be seen even after 1 yr. Patients may survive serious neurologic events, such as cerebral hemorrhage, CPM, and meningitis.
Fishing down the food chain revisited: Modeling exploited trophic systems

Abstract Several highly cited papers suggest that commercial fishing is altering marine ecosystems by “fishing down the food chain”. Recent evidence calls into question the generality of the original findings, but the papers all raise the question: what mechanisms lie behind exploitation patterns in a trophic system? This paper develops a simple model that shows how economic factors drive patterns of exploitation in a trophic system. We show that while fishing down the food chain is possible, there is no reason to suppose that the relevant economic factors favor such an outcome. As we show, other patterns are just as plausible. We also discuss and show how an index of trophic level-weighted harvest is not necessarily a good indicator of ecosystem health if biomass abundance is important.
Affinity of myasthenia drugs to acetylcholinesterase and acetylcholine receptor.

Abstract The effects of three myasthenia drugs on activities of ACh-esterase and ACh-receptor were determined in a membrane preparation of Torpedo electroplax. The hydrolysis of ACh by ACh-esterase was inhibited competitively by neostigmine and pyridostigmine, with the former being the most effective. There was general agreement between the relative affinities of these drugs and their effectiveness in treatment of myasthenia, which points to the usefulness of this membrane preparation for preclinical screening of myasthenia drugs. Edrophonium inhibited ACh-esterase in a mixed competitive-noncompetitive manner, and exhibited an unexpectedly high affinity for the ACh-receptor, only 2.6-fold lower than its affinity for ACh-esterase. It is suggested that, at the dose used in myasthenia, edrophonium acts as an in vivo activator of the ACh-receptor.
Interfacial Photoredox Molecular Interactions: A New Class of Hill Reagents for Photosystem II Reaction Centers

Photosynthetic reaction centers are molecular photovoltaic structures that are of significant interest in the field of nanoscale science and technology. We report here the results of an extensive experimental survey and characterization of over 20 species of transition-metal compounds for their activity in the Hill reaction at the lipid−water interface of Photosystem II (PSII) membrane fragments. Four new PSII Hill reagents were identified: PtCl4, [PtCl6]2-, [OsCl6]2-, and [RuCl6]2-. Each can be photosynthetically reduced by PSII. The negative charge of the metal compound species is apparently essential for their interaction with the reducing site of PSII. When PtCl4 is dissolved in water, it combines with water molecules to form H2[PtCl4(OH)2], which can dissociate to the negatively charged species [PtCl4(OH)2]2- at neutral pH. These findings could have significant implications for photosynthesis, nanoscale science, and nanofabrication in the field of biometallocatalysis.
A Critical Appraisal of the Evidence for Selective Nerve Root Injection in the Treatment of Lumbosacral Radiculopathy

Abstract DePalma MJ, Bhargava A, Slipman CW. A critical appraisal of the evidence for selective nerve root injection in the treatment of lumbosacral radiculopathy. Objective To critically review the best available trials of the utility of transforaminal epidural steroid injections (TFESIs) or selective nerve root blocks (SNRBs) to treat lumbosacral radiculopathy. Data Sources MEDLINE (PubMed, Ovid, MDConsult), EMBASE, and the Cochrane database. Databases were searched from inception through 2003. Study Selection A database search was conducted by using the following key words: prospective , transforaminal and foraminal epidural steroid injections , selective nerve root block and injection , and periradicular and nerve root injection . We included English-language, prospective, randomized studies of patients with lower-limb radicular symptoms treated with fluoroscopically guided nerve root or transforaminal epidural injections. Data Extraction Data were compiled for each of the following categories: inclusion criteria, randomization protocol, total number of subjects enrolled initially and at final analysis, statistical analysis utilized, documentation of technique, outcome measures, follow-up intervals and results (positive or negative), and reported complications. These data were abstracted by 1 reviewer and reviewed by a second. Study quality was assessed with the system developed by the Agency for Health Care and Policy Research. Data Synthesis We selected 6 articles for review. Our analysis identified a single article as the highest quality study addressing the appropriate use of TFESIs or therapeutic SNRBs. Coupled with the evidence provided by 4 other articles (1 article was excluded because its patients were not truly randomized), our review of the evidence for TFESIs found level III (moderate) evidence in support of these minimally invasive and safe procedures in treating painful radicular symptoms. However, conclusive evidence (level I) is lacking. Conclusions The evidence for TFESIs reveals level III (moderate) evidence in support of these minimally invasive and safe procedures in treating painful lumbar radicular symptoms. Current studies support use of TFESIs as a safe and minimally invasive adjunct treatment for lumbar radicular symptoms. However, more prospective, randomized, placebo-controlled studies using sham procedures are needed to provide conclusive evidence for the efficacy of TFESIs in treating lumbar radicular symptoms.
Different slopes for different folks: Process analysis of spatial aptitude

Adults differing in spatial ability were tested on problems involving the mental rotation of familiar alphanumeric stimuli and unfamiliar stimuli drawn from the Primary Mental Abilities Space Test. Individual differences in spatial ability were associated with speed rather than accuracy of mental rotation processes. Ability differences were correlated with the time to rotate familiar alphanumerics and the additional time to encode, compare, and rotate unfamiliar stimuli. The results are discussed in terms of differences in elementary information processes associated with the representation and transformation of visual information.
Separations of basic amino acid benzyl esters by pH-zone-refining counter-current chromatography

pH-Zone-refining counter-current chromatography was applied to the separation of basic amino acid benzyl esters. The method uses a retainer base in the stationary phase to retain analytes in the column and an eluent acid to elute the analytes in the decreasing order of pKa and hydrophilicity. The preparative capability of the method is demonstrated in the separation of a 10-g quantity of the sample.
Assessment of estrogen receptormonoclonal antibody interaction by high-performance liquid chromatography

Abstract High performance liquid chromatography (HPLC) was employed as a means of analyzing estrogen receptor(ER)antibody recognition. This technique takes advantage of the fact that the majority of γ-globulinantigen complexes do not interact with the anion-exchange resins selected. A variety of monoclonal (MAb) and polyclonal antibodies (PAb) raised against ER and ER-associated proteins were assessed for their chromatographic behaviour after association with charged ER, based upon properties of size, shape, and surface charge. ER exhibits polymorphism, several isoforms being present in target cells. The monoclonal antibody H222Spy demonstrated discrete specificity for the 150 m M ER isoform (normally eluting at 150 m M phosphate) from the high-performance ion-exchange chromatography column which was eluted unretained when complexed with antibody. However, the monoclonal reagent D547Spy interacted directly with anion-exchange columns (SynChropak AX-1000 and Altex DEAE-5PW), complicating a clear evaluation of ERMAb association. Only 50–60% of the 150 m M ER isoform was eluted at a lower salt concentration. Few conclusions could be drawn with respect to MAb interaction with the 50–60 m M ER isoform (normally eluting at 50–60 m M phosphate) since the antibodyreceptor complex was also eluted at the same phosphate concentration. In addition, polyclonal and monoclonal antibodies to the ER and ER-associated proteins were assessed by HPLC. At present, heat shock proteins and protein kinase activity have been shown by other techniques to be associated with the ER. Size-exclusion resins, such as TSK 3000 SW, were employed in a fast method of determining ER isoformantibody recognition. Thus, HPLC may be used to analyze soluble antibodyantigen interactions rapidly, with high recovery of biological activity.
Ligand-induced conformational changes observed in single RNA molecules.

We present the first demonstration that fluorescence resonance energy transfer can be used to track the motion of a single molecule undergoing conformational changes. As a model system, the conformational changes of individual three-helix junction RNA molecules induced by the binding of ribosomal protein S15 or Mg2+ ions were studied by changes in single-molecule fluorescence. The transition from an open to a folded configuration was monitored by the change of fluorescence resonance energy transfer between two different dye molecules attached to the ends of two helices in the RNA junction. Averaged behavior of RNA molecules closely resembles that of unlabeled molecules in solution determined by other bulk assays, proving that this approach is viable and suggesting new opportunities for studying protein–nucleic acids interactions. Surprisingly, we observed an anomalously broad distribution of RNA conformations at intermediate ion concentrations that may be attributed to foldability differences among RNA molecules. In addition, an experimental scheme was developed where the real-time response of single molecules can be followed under changing environments. As a demonstration, we repeatedly changed Mg2+ concentration in the buffer while monitoring single RNA molecules and showed that individual RNA molecules can measure the instantaneous Mg2+ concentration with 20-ms time resolution, making it the world’s smallest Mg2+ meter.
A note on the design of insulating bushings

THE break-down of an insulator usually sets in at the spot where the density of the electrostatic flux due to the conductor it is intended to insulate, is a maximum; for, as is well-known, this density is a measure of the volts per centimeter acting at that point upon the insulating medium. Observation of the discharges from an electrostatic machine shows that the atmosphere around a highly charged conductor breaks down most readily at points and sharp corners, while both theory and experiment show the advantage, if corona is to be avoided, of using, for a high-voltage transmission line, conductors of large diameter.
Discovery systems in ubiquitous computing

Ubiquitous computing introduces unique requirements for discovery technologies, which let services and devices become aware of each other without explicit human administration. Discovery lets services and devices spontaneously become aware of the availability and capability of peers on the network without explicit administration. In practice, this means that a client can discover and potentially use a device without prior knowledge of it. Although discovery is a necessary component of ubiquitous computing, the wide range of discovery systems in use today reflects the varied needs of the communities from which they originated. Some of these features are appropriate for ubiquitous computing, but others require further research and development.
Dynamic light scattering studies of porcine submaxillary mucin fractions in dilute solution at intermediate scattering vectors

We report dynamic light scattering measurements over a wide range of scattering vectors for fractionated samples of porcine submaxillary mucin (PSM) glycoproteins in two different solvents: 0.1M NaCl, and 6M GdnHCl. The relaxation spectrum has been successfully resolved into a slow mode corresponding to pure translational diffusion and a fast mode containing information on the relaxation times for intramolecular motion. Analysis of the slow mode permits a light scattering evaluation of the polydispersity of these high molecular weight mucin glycoprotein fractions. Determination of the longest intramolecular relaxation times tau 1 shows that these are much longer for the PSM fractions in 0.1M NaCl compared to 6M GdnHCl. These data are consistent with earlier studies showing that the chain conformation is the same in both solvents, but that in 0.1M NaCl, the PSM glycoprotein undergoes a self-association process that is end-to-end in nature. Since the tau 1 value is intimately related to the viscoelastic behavior of PSM solutions and gels, it is interesting to speculate that the end-to-end association process may be physiologically important.
IN THE FACE OF THREAT: Organized Antifeminism in Comparative Perspective

This article develops a cross-cultural and historical theory of antifeminist movements. Such movements are composed of two elements, which often involve very different types of people: vested-interest groups and voluntary associations. Five predictions concerning the social composition of antifeminist vested-interest groups and voluntary organizations and antifeminist movement ideology are derived from the theory. Evidence taken from existing literature pertaining to both first-wave (nineteenth to mid-twentieth century) and second-wave (since 1968) antifeminist movements in a variety of nations is reviewed. Substantial support is found for all five predictions. We conclude that antifeminist movement adherents are responding to realistic threats. For men and vested-interest groups, the threat is primarily class based, but also extends to their status as family head; for women, it is primarily status based as wives and mothers, but also class-based inasmuch as their husbands' economic interests are threatened.
Exploring the competitive and quality potentials of internet radio

The advancement of technology is not limited anymore to merely the sophistication of the desktop PC. Integrated items such as wireless capacity to broadband connectivity to software intricacy have conspired to propel the rapid diffusion of the internet into all genres of life. As found through a review of literature and conceptual modelling, the true value of the internet might just be found in its complementary potential with traditional forms of product delivery channels, not its stand-alone wherewithal as a competitor. The radio industry has the opportunity now to amalgamate the internet on the cusp of its real, quantifiable penetration and diffusion into the culture. Station management can strategically leverage the internet to expand its demographic base and broaden advertising opportunities.
Improving Cattle Nutrition on the Great Plains with Shrubs and Fecal Seeding of Fourwing Saltbush

Two in vitro trials were conducted for estimates of dietary percentage of fourwing saltbush (Atriplex canescens; FS) or winterfat (Krascheninnikovia lanata; WF) for improved dietary digestibility when cattle graze mature cool-season grass. Three in vitro trials were conducted to estimate percentage of FS and WF seeds that could survive passage through the bovine gastro-intestinal tract (GIT) with potential for fecal seeding. Mixtures of FS and mature smooth bromegrass (Bromus inermis; SB) or WF and SB had greater apparent digestibility than SB alone (P < 0.0001). There were positive linear relationships (r2 ≥ 0.93) between the amount of each shrub in digested mixtures and digestibility. Similar relationships were observed with mixtures of FS and mature Altai wildrye (Leymus angustus). Germination of Dakota FS seeds in the first trial, incubated for 24 or 48 h, was 55% and 47%, respectively, with no difference in germination of seeds for the 24- and 48-h incubations (P = 0.26), but more seeds germinated if incubated versus not (P ≤ 0.002). Germination of Utah FS seeds, which were incubated for 24 or 48 h with high-, medium-, or low-quality forage, averaged 9% and 8%, respectively. Length of incubation, forage quality, and their interaction did not influence germination (P ≥ 0.45). Germination of nonincubated Utah FS seeds was 21% and greater than for incubated seeds (P = 0.004). Average germination of WF seeds was 0.6% and 0.1% for 24- and 48-h incubations, respectively, with incubation length, forage quality, and their interaction not significant (P ≥ 0.31). Nonincubated WF seeds had greater germination (42%) than incubated seeds (P < 0.0001). Results from the third trial were confirmatory for Dakota FS seed. FS and WF can improve diet quality of grazing cattle in late summer through winter, and some FS seeds have potential for fecal seeding.
Analysis of coefficient quantization noise in block digital filters

Coefficient quantization noise (CQN) in SVD block digital filters depends on the structure of their SISO filters. The problem of growing coefficient values in direct-form-derived block filters is analyzed. It is shown that normal form is free from this problem. Analysis of output CQN power shows different behavior from roundoff noise, in that it increases with block size. A new quantization method is suggested to reduce the output CQN. It is very effective for large block size. >
Clocking Gender Differences Televised Olympic Clock Time in the 1996—2006 Summer and Winter Olympics

Analysis of all 348 prime-time hours of the 1996—2006 Olympic telecasts (three Summer, three Winter) pinpointed trends in coverage of men's and women's sports. Results indicate that while men athletes and events received the majority of clock time in all six Olympic telecasts, the Summer Olympic telecasts treated women far more equitably than the Winter Olympic telecast. The longitudinal study does not offer any reason to feel that coverage of women's athletics is improving over time, finding that the proportion of clock time devoted to men's and women's sports is relatively the same in 2006 compared to ten years earlier.
Lumps, bumps and funny shaped heads

Abnormal head shape may be due to congenital or acquired conditions including birth injury, and is the most common reason for referral to a paediatric neurosurgeon.1 2 Birth injuries may present immediately or late, and imaging is rarely required in order to correctly identify the type of injury. However, an understanding of the underlying pathophysiological processes is helpful in order to appreciate potential complications that can occur in association with these injuries. When assessing an infant or child with an abnormally shaped head, it is important to differentiate between birth moulding, positional plagiocephaly and craniosynostosis which may require surgical treatment. The aim of this article is to explain the differences between these conditions, how they are best imaged and demonstrate some of the imaging findings. Definitions are given in box 1. The skull is formed from multiple separate bones that develop in the first weeks of embryonic life from mesenchyme enveloping the developing brain. The bones progressively ossify later in gestation. At birth the skull bones are separated by connective tissue sutures which allow movement and alteration in the shape of the skull vault during birth. The major sutures include the metopic suture located in the midline between the two frontal bones, the coronal suture between the frontal and parietal bones, the sagittal suture midline between the two parietal bones, and the lambdoid suture between the parietal and occipital bones. The fontanelles are widened, membranous areas at the intersection of sutures. In relation to the major sutures, the anterior fontanelle (AF) is situated between the metopic, sagittal and coronal sutures, with the posterior fontanelle (PF) found at the intersection of the sagittal and lambdoid sutures. Skull growth is primarily driven by growth of the underlying brain which proceeds rapidly to 90% of adult size in the first year of …
Communication-aware face detection using noc architecture

Face detection is an essential first step towards many advanced computer vision, biometrics recognition and multimedia applications, such as face tracking, face recognition, and video surveillance. In this paper, we proposed an FPGA hardware design with NoC (Network-on-Chip) architecture based on an AdaBoost face detection algorithm. The AdaBoost-based method is the state-of-the-art face detection algorithm in terms of speed and detection rates and the NoC provides high communication capability architecture. This design is verified on a Xilinx Virtex-II Pro FPGA platform. Simulation results show the improvement in speed 40 frames per second compared to software implementation. The NoC architecture provides scalability so that our proposed face detection method can be sped up by adding multiple classifier modules.
Site Response from Incident Pnl Waves

We developed a new method of determining site response and amplification for use in hazard analysis and station corrections. The method employs the conversion of P to S energy beneath a soft-rock station, which results in complex receiver functions that are frequency and amplitude dependent. At low frequencies ( 0.5 Hz) can be normalized to these low-frequency levels to quantify the amount of high-frequency amplification. Our results agree with previous studies of the Los Angeles Basin and provide the means of calibrating station responses at high frequencies.
The Orphan Receptor COUP-TF Binds to a Third Glucocorticoid Accessory Factor Element within the Phosphoenolpyruvate Carboxykinase Gene Promoter

The phosphoenolpyruvate carboxykinase (PEPCK) gene promoter contains a glucocorticoid response unit (GRU) that includes, as a linear array, two accessory factor binding sites (AF1 and AF2) and two glucocorticoid receptor binding sites. All of these elements are required for a complete glucocorticoid response. AF1 and AF2 also partially account for the response of the PEPCK gene to retinoic acid and insulin, respectively. A second retinoic acid response element was recently located just downstream of the GRU. In this study we show that mutation of the 3' half-site of this element results in a 60% reduction of the glucocorticoid response of PEPCK promoter-chloramphenicol acetyltransferase (CAT) fusion constructs in transient transfection assays, thus the half-site is now termed AF3. A variety of assays were used to show that chicken ovalbumin upstream promoter transcription factor (COUP-TF) binds specifically to AF3 and that upstream stimulatory factor (USF) binds to an E-box motif located 2 base pairs downstream of AF3. Mutations of AF3 that diminish binding of COUP-TF reduce the glucocorticoid response, but mutation of the USF binding site has no effect. The functional roles of AF1, AF2, and AF3 in the glucocorticoid response were explored using constructs that contained combinations of mutations in all three elements. All three elements are required for a maximal glucocorticoid response, and mutation of any two abolish the response.
Mycotic Aneurysm of the Aortic Arch Presenting With Left Vocal Cord Palsy

We report a case of a 71-year-old man with a mycotic aneurysm of the aortic arch who presented with progressive hoarseness. Three weeks prior to this event the patient was admitted to an outside hospital in septic condition and was diagnosed with a mycotic abdominal aortic aneurysm. Resection of the infected abdominal aortic aneurysm with right axillofemoral and femoral-femoral bypass grafts was performed and the patient was discharged home on intravenous antibiotics. At our institution, the aortic arch aneurysm was treated with extensive debridement and replaced with a Dacron prosthesis under circulatory arrest with antegrade cerebral perfusion through the axillofemoral bypass.
Characterization of the electrically evoked release of substance P from dorsal root ganglion neurons: methods and dihydropyridine sensitivity

The mechanism by which dihydropyridines (DHPs) modulate the electrically evoked or KCI-induced release of substance P (SP) from embryonic chick dorsal root ganglion (DRG) neurons was investigated in the present study. The release of SP, as measured by radioimmunoassay (RIA), was characterized in terms of its dependence on extracellular calcium ion, its stimulus-response relationship, its sensitivity to the calcium-channel blocker omega conus toxin (omega-CgTx), and its modulation by the DHPs Bay K 8644 and nifedipine. Here it is reported that omega-CgTx (1 microM) blocked the electrically evoked release of SP. In contrast, the calcium-channel agonist Bay K 8644 (5 microM) facilitated the release of SP (by 45%), whereas the calcium-channel antagonist nifedipine (5 microM) was without effect. When the release of SP was triggered by depolarization of cultures with 60 mM KCI, the actions of the DHPs became much more pronounced. Under these conditions, Bay K 8644 facilitated (by 115%), whereas nifedipine inhibited (by 58%), peptide secretion. Voltage-clamp analysis of DRG cell calcium currents demonstrated that these actions of omega-CgTx, Bay K 8644, and nifedipine are explicable in terms of their effects on the slowly inactivating (L-type) calcium current. On the basis of these findings, it is suggested that the SP release mechanism exhibits DHP sensitivity due to the involvement of L-type calcium channels in the neurosecretory process. This model predicts that the voltage and time-dependent antagonist actions of nifedipine are sufficient to explain its failure to inhibit the electrically evoked release of SP.
Nitride /organic hybrid heterostructures for photodetector devices

We report on the study of incorporation of organic thin film semiconductors with GaN to explore new types of photodetector or solar cell application. Photovoltaic effect and photoconductivity gain have been demonstrated using GaN/CuPc and GaN/alpha -NPD hybrid device structure, which offer new opportunities in design of versatile optoelectronic devices.
Thermosensitive and ampholytic hydrogels for salt solution

A series of N-isopropylacrylamide/[[3-(methacryloylamino)propyl]dimethy(3-sulfopropyl)ammonium hydroxide] (NIPAAm/MPSA) copolymer hydrogels were prepared with various compositions. Swelling of the hydrogels in water, aqueous NaCl, KCl, CaCl2, and MgCl2 solutions was studied. NIPAAm/MPSA hydrogels have a higher degree of swelling in water and salt solutions than that of poly(N-isopropylacrylamide) (PNIPAAm). Also, NIPAAm/MPSA hydrogels are more salt resistant when deswelling in salt solutions. For 11 mol %) leads to better salt resistance but a decrease in thermosensitivity. The swelling of NIPAAm/MPSA hydrogel in 0.05M NaCl is non-Fickian. In NaCl and KCl aqueous solutions, the zwitterionic hydrogels do not show obvious antipolyelectrolyte swelling behavior, whereas in divalent salt CaCl2 and MgCl2 solutions, the swelling ability of NIPAAm/MPSA hydrogels is enhanced at low salt concentration, then decreases with further increase in salt concentration. The lower critical solution temperatures of NIPAAm/MPSA hydrogels are also affected by concentrated salt solution. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 2032–2037, 2003
Haptic display of realistic tool contact via dynamically compensated control of a dedicated actuator

High frequency contact accelerations convey important information that the vast majority of haptic interfaces cannot render. Building on prior work, we present an approach to haptic interface design that uses a dedicated linear voice coil actuator and a dynamic system model to allow the user to feel these signals. This approach was tested through use in a bilateral teleoperation experiment where a user explored three textured surfaces under three different acceleration control architectures: none, constant gain, and dynamic compensation. The controllers that use the dedicated actuator vastly outperform traditional position-position control at conveying realistic contact accelerations. Analysis of root mean square error, linear regression, and discrete Fourier transforms of the acceleration data also indicate a slight performance benefit for dynamic compensation over constant gain.
Moxibustion Another Traumatic Folk Remedy

An approach emphasizing an understanding of differing patient and family models of illness and the implementation of culturally appropriate health care is described. The physician who observes a practice such as moxibustion should attempt to gain an understanding of the parents' "model" of illness, develop and maintain rapport with the family, and attempt to develop a culturally appropriate treatment plan which minimizes the injurious practice. Counselors of the same ethnic group who are more acculturated to our society may be very helpful.
ULTRA-LOW COMPLEXITY CONTROL FOR ADHOC MOBILE SENSOR NETWORKS

We introduce an ultra-low complexity decentralized control scheme for adhoc mobile sensor networks that can be used for a great variety of sensing tasks. Sensor networks using this control scheme are easy to configure, can operate completely autonomously without supervision, and automatically adapt to various environmental changes. Moreover, they are robust to individual sensor failure as well as other disturbances and scale very well. Finally, they allow for simple dynamic adhoc networks that can route data based on available sensor connectivity. We demonstrate the versatility and effectiveness of sensor homogeneous and heterogeneous sensor networks using the proposed control scheme in simulations of unmanned aerial vehicles performing target detection, tracking, and reporting tasks.
Parsimonious sound field synthesis using compressive sampling

Reproducing a sampled sound field over a two-dimensional area using an array of loudspeakers is a problem with well-appreciated applications to acoustics and ultrasound treatement. Loudspeaker signal design has traditionally relied on a (possibly regularized) least-squares criterion. The fresh look advocated here, permeates benefits from advances in variable selection and compressive sampling by casting the sound field synthesis as a sparse linear regression problem that is solved by the least absolute shrinkage and selection operator (Lasso). Analysis and simulations demonstrate that the novel approach exhibits superb performance even for under-sampled sound fields, where least-squares methods yield inconsistent field reproduction. In addition, Lasso-based synthesis enables judicious placement of parsimonious loudspeaker arrays.
An analysis of flare properties by observed temperature and emission measure profiles

Abstract The physical properties of the thermal phase of a solar flare are analyzed by means of observed electron temperature variations derived from flux intensity ratios of continuum soft X-ray spectra. The analysis is based on the non-equilibrium energy balance equation and invokes a self-similar formalism which reduces this non-linear, second-order partial differential equation in two independent variables (length and time) to a more tractable non-linear, first-order Ricatti equation. Plasma density is the principal unknown variable contained in the Ricatti equation which also contains first-order time derivatives and first and second order spatial derivatives of temperature. The solution of this equation is obtained first by substituting known analytic expressions for the temperature derivatives, and secondly by numerically integrating the resulting equation under the boundary conditions specified by the imposed initial density and the final density gradient. Solutions are obtained by adjusting two imperfectly known constants in the equation to satisfy the asymptotic density gradient final boundary condition. The methodology is applied to the moderate sized flare of 28 January, 1982, for which a density profile is deduced under various parametric conditions.
Sicklepod (Senna obtusifolia) germination and emergence as affected by environmental factors and seeding depth

Abstract Laboratory and greenhouse experiments were conducted to determine the effect of light, temperature, solution pH, solution osmotic potential, and oxygen concentration on sicklepod germination and radicle plus hypocotyl elongation and seeding depth on emergence. Scarified, nondormant sicklepod seeds were used for these experiments. Sicklepod germination was not influenced by red or far-red light nor was light required for germination, which averaged 81% over all light treatments. Sicklepod germinated over a range of constant temperatures from 15 to 50 C, with optimum germination between 15 and 30 C. Germination was optimal near pH 6 for temperatures of 15 and 30 C. Germination and radicle plus hypocotyl length decreased with decreasing solution osmotic potential, and no germination occurred at a solution osmotic potential of −0.75 MPa at 15 C during 7 d incubation. Germination was greater at 20% oxygen than at 2% oxygen. The mean emergence depth for sicklepod was 3.3 and 4.6 cm in a highly disturbe...
Survival of Ducks Banded in the Boreal Forest of Alaska

Limited information is available about the population dynamics of ducks in the boreal forest. We conducted an analysis of recovery data from 5 species of ducks banded in the boreal forest of Alaska, USA, during 1959–1966, and records of 3 species of ducks banded during 1989–2000, with the objective of examining sources of variation in survival and sampling probability and to complement recent studies of the breeding ecology of ducks in the boreal forest. Survival of ducks during 1959–1966 was species- and year-specific. During 1989–2000, survival of northern pintail (Anas acuta) was age-, sex-, and year-specific. Age-class by sex interaction, without year-specificity, however, best-described survival of mallard (A. platyrhynchos) and green-winged teal (A. crecca). Annual survival of male ducks from the Alaska boreal forest was generally similar to annual survival of the same species banded in the midcontinent. Survival probability of female ducks from the Alaska boreal forest, however, was generally higher than survival of female ducks from midcontinent regions. Sampling probability during 1989–2000 was lower for females than males, and increased after 1996, concurrent with the initiation of electronic band reporting. Our results suggest that patterns of duck survival differ between the boreal forest and the midcontinent, especially for after-hatch-year females. Regional variation in survival and reproduction and the factors affecting these parameters should continue to be monitored and considered in continental management plans.
Effects of Environmental Flow upon Tropical Cyclone Structure

Abstract Numerical simulations of tropical-cyclone-like vortices are performed to analyze the effects of unidirectional vertical wind shear and translational flow upon the organization of convection within a hurricane’s core region and upon the intensity of the storm. A series of dry and moist simulations is performed using the Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model version 5 (MM5) with idealized initial conditions. The dry simulations are designed to determine the patterns of forced ascent that occur as the vortex responds to imposed vertical wind shear and translational flow, and the mechanisms that modulate the vertical velocity field are explored. The moist simulations are initialized with the same initial conditions as the dry runs but with a cumulus parameterization and explicit moisture scheme activated. The moist simulations are compared to the dry runs in order to test the hypothesis that the forced vertical circulation modes modulate the convection...
Influence of muscle length and force on endurance and pressor responses to isometric exercise

Experiments were performed to determine whether endurance time, mean arterial pressure, or heart rate was related to either muscle length or external torque production in humans during isometric knee extension. Eight men and nine women performed isometric knee extension to the endurance limit at each of three muscle lengths, determined by knee angles of 40 degrees (0.698 rad, shortest), 60 degrees (1.047 rad, intermediate), and 90 degrees (1.571 rad, longest), and at intensities of 30 and 50% maximal voluntary contraction (MVC). Knee extension forms an ascending-descending length-torque curve, and lengths were chosen to result in different external torques. MVC was greatest at a knee angle of 60 degrees (P < 0.05 vs. 40 degrees, 90 degrees), with no significant difference between 90 degrees and 40 degrees. Endurance time was inversely related to muscle length, independent of torque production, at 30% MVC [40 degrees, 395 +/- 139 (SE); 60 degrees, 237 +/- 60; 90 degrees, 165 +/- 51 s; P < 0.05 vs. each other] and 50% MVC (40 degrees, 176 +/- 64; 60 degrees, 137 +/- 40; 90 degrees, 85 +/- 23 s; P < 0.05 vs. each other). Evidence is presented that endurance is a function of internal muscle force and not resultant external torque. The experimental design allowed the relationship of external torque and cardiovascular responses to be examined independent of exercise intensity. Muscle mass was also controlled in that the same muscle group was involved in all contractions. There were no differences in mean arterial pressure, heart rate, or rating of perceived exertion at any percentage of endurance time under any condition.(ABSTRACT TRUNCATED AT 250 WORDS)
