Full Text Available This study investigated the effect of short silent animations on pre-intermediate EFL learners writing. A homogenized group of 60 participants was non-randomly chosen and assigned as the control and experimental groups. Those in the control group watched five short animations with dialogue, while those in the experimental group had five short animations which were silent. The procedure lasted 10 sessions. In both groups, the participants were asked to write five writings regarding the subjects of the animations during the term and each of the writings should have contained a minimum of 90 and maximum of 140 words. The participants were provided both oral and written feedback. At the end of the instruction, a sample PET writing posttest was administered to both groups, an independent samples t-test was run on the mean scores of the two groups, and the results (t = -2.02, p = 0.037˂0.05 revealed that the experimental group outperformed the control group.

Pacemaker with remote monitoring (PRM) may be useful for silent atrial fibrillation (AF) detection. The aims of this study were to evaluate the incidence of silent AF, the role of PRM, and to determine predictors of silent AF occurrence. Three hundred elderly patients with permanent pacemaker (PPM) were randomly assigned to the remote group (RG) or control group (CG). All patients received PPM with remote monitoring capabilities. Primary end point was AF occurrence rate and the secondary end points were time to AF detection and number of days with AF. During the average follow-up of 15.7±7.7 months, AF episodes were detected in 21.6% (RG = 24% vs CG = 19.3%, P = 0.36]. There was no difference in the time to detect the first AF episode. However, the median time to detect AF recurrence in the RG was lower than that in the CG (54 days vs 100 days, P = 0.004). The average number of days with AF was 16.0 and 51.2 in the RG and CG, respectively (P = 0.028). Predictors of silent AF were left atrial diameter (odds ratio [OR] 1.2; 95% CI = 1.1-1.3; P pacemaker; left atrial diameter and diastolic dysfunction were predictors of its occurrence. AF monitoring by means of pacemaker is a valuable tool for silent AF detection and continuous remote monitoring allows early AF recurrence detection and reduces the number of days with AF. © 2015 Wiley Periodicals, Inc.

The prevalence of silent myocardial ischemia was retrospectively assessed in a group of 100 consecutive patients with angiographically proved coronary artery disease, and diagnostic ECG, by symptom-limited exercise thallium-201 scintigraphy. Twenty-four patients had no evidence of ischemia despite adequate exercise level. So among 76 patients with exercise induced ischemia, only 33 patients (43%) stopped exercise due to anginal pain (symptomatic ischemia: Group 3). And 43 patients with asymptomatic ischemia composed of 23 patients (30%) with ECG change (Group 2B) and 20 patients (26%) without ECG change (Group 2A). Patients background including the history of old myocardial infarction and diabetes mellitus, were similar among Group 2A, 2B, and Group 3. Our Major observation was that the extent and severity of quantified SPECT perfusion defects was nearly identified between 3 groups. Thus in this study group, there was a rather high prevalence rate of silent ischemia (57%) by exercise thallium-201 criteria. Patients with silent ischemia, associated with positive and negative exercise ECG findings, and those with exercise angina had similar background and comparable amount of jeopardized myocardium.

While routine renal imaging following ureteroscopy for urinary calculi has been recommended to screen for asymptomatic "silent" obstruction, the rate of silent obstruction following percutaneous nephrolithotomy (PCNL) remains poorly defined, and no consensus recommendations exist on routine postoperative imaging. At our institution, we sought to assess the incidence of silent hydronephrosis (SH), as a screen for obstruction, following PCNL. The records of all 162 patients who met study inclusion criteria were reviewed. Of this group, 112 patients presented for their scheduled renal ultrasonography 4 - 6 weeks following stent removal to screen for SH. Asymptomatic patients found to have ultrasonographic evidence of hydronephrosis were further analyzed. SH was noted in 16% (18/112) of patients. Two required subsequent ureteroscopic stone extraction (1.8%), one of which also underwent endoureterotomy for a ureteral stricture. Four patients (22%) had stable hydronephrosis and declined functional imaging, 2 patients (11%) had a known partial ureteropelvic junction obstruction and declined intervention. SH resolved spontaneously in 50% (9/18) with a mean time to resolution of 6.3 months. There was no difference in stone complexity based on Guy's stone score between groups, 2.8 (± 0.92) vs. 2.4 (± 1.03), p = 0.34. Although not statistically significant, patients with SH were more likely to have had residual stone fragments postoperatively, 39% (7/18) vs. 19% (18/94), p = 0.067. SH following, PCNL was identified in 16% of this screened population, with the majority requiring no intervention. However, SH may be attributed to residual stone or stricture, which may have been otherwise unrecognized in up to 2% of patients undergoing PCNL. Consideration should be given for routine postoperative ultrasound to screen for silent obstruction following PCNL.

Purpose: To investigate the safety and effectiveness of stereotactic radiosurgery (SRS) in patients with a silent corticotroph adenoma (SCA) compared with patients with other subtypes of non–adrenocorticotropic hormone staining nonfunctioning pituitary adenoma (NFA). Methods and Materials: The clinical features and outcomes of 104 NFA patients treated with SRS in our center between September 1994 and August 2012 were evaluated. Among them, 34 consecutive patients with a confirmatory SCA were identified. A control group of 70 patients with other subtypes of NFA were selected for review based on comparable baseline features, including sex, age at the time of SRS, tumor size, margin radiation dose to the tumor, and duration of follow-up. Results: The median follow-up after SRS was 56 months (range, 6-200 months). No patients with an SCA developed Cushing disease during the follow-up. Tumor control was achieved in 21 of 34 patients (62%) in the SCA group, compared with 65 of 70 patients (93%) in the NFA group. The median progression-free survival (PFS) was 58 months in the SCA group. The actuarial PFS was 73%, 46%, and 31% in the SCA group and was 94%, 87%, and 87% in the NFA group at 3, 5, and 8 years, respectively. Silent corticotroph adenomas treated with a dose of ≥17 Gy exhibited improved PFS. New-onset loss of pituitary function developed in 10 patients (29%) in the SCA group, whereas it occurred in 18 patients (26%) in the NFA group. Eight patients (24%) in the SCA group experienced worsening of a visual field deficit or visual acuity attributed to the tumor progression, as did 6 patients (9%) in the NFA group. Conclusion: Silent corticotroph adenomas exhibited a more aggressive course with a higher progression rate than other subtypes of NFAs. Stereotactic radiosurgery is an important adjuvant treatment for control of tumor growth. Increased radiation dose may lead to improved tumor control in SCA patients

In this study, the authors (a) investigated whether a group of people with severe aphasia could learn a vocabulary of pantomime gestures through therapy and (b) compared their learning of gestures with their learning of words. The authors also examined whether gesture therapy cued word production and whether naming therapy cued gestures. Fourteen people with severe aphasia received 15 hr of gesture and naming treatments. Evaluations comprised repeated measures of gesture and word production, comparing treated and untreated items. Baseline measures were stable but improved significantly following therapy. Across the group, improvements in naming were greater than improvements in gesture. This trend was evident in most individuals' results, although 3 participants made better progress in gesture. Gains were item specific, and there was no evidence of cross-modality cueing. Items that received gesture therapy did not improve in naming, and items that received naming therapy did not improve in gesture. Results show that people with severe aphasia can respond to gesture and naming therapies. Given the unequal gains, naming may be a more productive therapy target than gesture for many (although not all) individuals with severe aphasia. The communicative benefits of therapy were not examined but are addressed in a follow-up article.

Silent Synapse-Based Circuitry Remodeling in Drug Addiction.

Dong, Yan

2016-05-01

Exposure to cocaine, and likely other drugs of abuse, generates α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor-silent glutamatergic synapses in the nucleus accumbens. These immature synaptic contacts evolve after drug withdrawal to redefine the neurocircuital properties. These results raise at least three critical questions: (1) what are the molecular and cellular mechanisms that mediate drug-induced generation of silent synapses; (2) how are neurocircuits remodeled upon generation and evolution of drug-generated silent synapses; and (3) what behavioral consequences are produced by silent synapse-based circuitry remodeling? This short review analyzes related experimental results, and extends them to some speculations. © The Author 2015. Published by Oxford University Press on behalf of CINP.

Silent pituitary adenomas are a subtype of adenomas characterized by positive immunoreactivity for one or more hormones classically secreted by normal pituitary cells but without clinical expression, although in some occasions enhanced or changed secretory activity can develop over time. Silent corticotroph adenomas are the classical example of this phenomenon. A series of about 500 pituitary adenomas seen over a period of 20 years were screened for modification in hormonal secretion. Biochemical and immunohistochemical data were reviewed. Two cases were retrieved, one silent somatotroph adenoma and one thyrotroph adenoma, both without specific clinical features or biochemical abnormalities, which presented 20 years after initial surgery with evidence of acromegaly and hyperthyroidism, respectively. While the acromegaly was controlled by a combination of somatostatin analogs and growth hormone (GH) receptor antagonist therapy, neurosurgery was necessary to manage the thyrotroph adenoma. Immunohistochemical examination demonstrated an increase in the number of thyroid stimulating hormone (TSH)-immunoreactive cells compared to the first tissue. Apparently, the mechanisms responsible for the secretory modifications are different, being a change in secretory capacity in the silent somatotroph adenoma and a quantitative change in the silent thyrotroph adenoma. These two cases, one somatotroph and one thyrotroph adenoma, are an illustration that clinically silent pituitary adenomas may in rare circumstances evolve over time and become active, as previously demonstrated in silent corticotroph adenomas.

This study aimed to assess the performance of a ''Silent'' zero time of echo (ZTE) sequence for T1-weighted brain imaging using a 7 T MRI system. The Silent sequence was evaluated qualitatively by two neuroradiologists, as well as quantitatively in terms of tissue contrast, homogeneity, signal-to-noise ratio (SNR) and acoustic noise. It was compared to conventional T1-weighted imaging (FSPGR). Adequacy for automated segmentation was evaluated in comparison with FSPGR acquired at 7 T and 1.5 T. Specific absorption rate (SAR) was also measured. Tissue contrast and homogeneity in Silent were remarkable in deep brain structures and in the occipital and temporal lobes. Mean tissue contrast was significantly (p < 0.002) higher in Silent (0.25) than in FSPGR (0.11), which favoured automated tissue segmentation. On the other hand, Silent images had lower SNR with respect to conventional imaging: average SNR of FSPGR was 2.66 times that of Silent. Silent images were affected by artefacts related to projection reconstruction, which nevertheless did not compromise the depiction of brain tissues. Silent acquisition was 35 dB(A) quieter than FSPGR and less than 2.5 dB(A) louder than ambient noise. Six-minute average SAR was <2 W/kg. The ZTE Silent sequence provides high-contrast T1-weighted imaging with low acoustic noise at 7 T. (orig.)

Evidence for presynaptically silent synapses in the immature hippocampus

International Nuclear Information System (INIS)

Yoon, Jae Young; Choi, Sukwoo

Silent synapses show NMDA receptor (NMDAR)-mediated synaptic responses, but not AMPAR-mediated synaptic responses. A prevailing hypothesis states that silent synapses contain NMDARs, but not AMPARs. However, alternative presynaptic hypotheses, according to which AMPARs are present at silent synapses, have been proposed; silent synapses show slow glutamate release via a fusion pore, and glutamate spillover from the neighboring synaptic terminals. Consistent with these presynaptic hypotheses, the peak glutamate concentrations at silent synapses have been estimated to be ≪170 μM, much lower than those seen at functional synapses. Glutamate transients predicted based on the two presynaptic mechanisms have been shown to activate only high-affinity NMDARs, but not low-affinity AMPARs. Interestingly, a previous study has developed a new approach to distinguish between the two presynaptic mechanisms using dextran, an inert macromolecule that reduces the diffusivity of released glutamate: postsynaptic responses through the fusion pore mechanism, but not through the spillover mechanism, are potentiated by reduced glutamate diffusivity. Therefore, we reasoned that if the fusion pore mechanism underlies silent synapses, dextran application would reveal AMPAR-mediated synaptic responses at silent synapses. In the present study, we recorded AMPAR-mediated synaptic responses at the CA3-CA1 synapses in neonatal rats in the presence of blockers for NMDARs and GABAARs. Bath application of dextran revealed synaptic responses at silent synapses. GYKI53655, a selective AMPAR-antagonist, completely inhibited the unsilenced synaptic responses, indicating that the unsilenced synaptic responses are mediated by AMPARs. The dextran-mediated reduction in glutamate diffusivity would also lead to the activation of metabotropic glutamate receptors (mGluRs), which might induce unsilencing via the activation of unknown intracellular signaling. Hence, we determined whether mGluR-blockers alter

Full Text Available This study aims to determine the prevalence of silent GI complications within a stable renal transplant population and to investigate whether the conversion to enteric-coated myco-phenolate sodium (EC-MPS, Myfortic; would improve symptom scores. This was a single-center, open-label, non-randomized, prospective study. Patients without any history of GI com-plaints were evaluated by means of the gastrointestinal symptom rating scale (GSRS, with subse-quent switch to EC-MPS in a group of patients. Silent complications were defined as patients who voiced no GI complaints at clinic visits despite a score of ≥ 2 on GSRS scale. A total of 236 stable patients participated in the trial. The prevalence of baseline scores ≥ 2 was relatively high with abdominal pain 29.66%, reflux 37.28%, indigestion 50%, constipation 58.47% and diarrhea 33.4%. Of 236 patients, 80 were converted to EC-MPS. There was statistically significant improvement on all scales in the subgroup of patients with GSRS score ≥ 2 (P< 0.05. In conclusion, the GSRS scale identified a high percentage of silent gastrointestinal complications in this renal transplant population. The converted patients with higher GSRS scores reported a sustained improvement.

Relativistic numerical cosmology with silent universes

Bolejko, Krzysztof

2018-01-01

Relativistic numerical cosmology is most often based either on the exact solutions of the Einstein equations, or perturbation theory, or weak-field limit, or the BSSN formalism. The silent universe provides an alternative approach to investigate relativistic evolution of cosmological systems. The silent universe is based on the solution of the Einstein equations in 1  +  3 comoving coordinates with additional constraints imposed. These constraints include: the gravitational field is sourced by dust and cosmological constant only, both rotation and magnetic part of the Weyl tensor vanish, and the shear is diagnosable. This paper describes the code simsilun (free software distributed under the terms of the reposi General Public License), which implements the equations of the silent universe. The paper also discusses applications of the silent universe and it uses the Millennium simulation to set up the initial conditions for the code simsilun. The simulation obtained this way consists of 16 777 216 worldlines, which are evolved from z  =  80 to z  =  0. Initially, the mean evolution (averaged over the whole domain) follows the evolution of the background ΛCDM model. However, once the evolution of cosmic structures becomes nonlinear, the spatial curvature evolves from ΩK =0 to ΩK ≈ 0.1 at the present day. The emergence of the spatial curvature is associated with ΩM and Ω_Λ being smaller by approximately 0.05 compared to the ΛCDM.

2016-11-01

The silent flange used for coupling different machines/systems to an eddy current dynamometer represents one of the modular components each test-bench should use. By introducing a silent flange into a dynamometer, the coupling steps are easier and faster. For an appropriate design, the silent flange was analyzed using dedicated software during different operation procedures and scenarios, for materials that allow easy manufacturing. This study shows that the design for this silent flange model has no danger of failure due to the small deformation and the values for the equivalent stresses. The silent flange coupling is suitable for the dynamometer for his high positioning accuracy, the zero backlash and the fact that there is no motion between the shafts.

BACKGROUND--Autonomic neuropathy provides a mechanism for the absence of symptoms in silent myocardial ischaemia, but characterisation of the type of neuropathy is lacking. AIM--To characterise and compare autonomic nerve function in patients with silent and symptomatic myocardial ischaemia. METHODS AND RESULTS--The Valsalva manoeuvre, heart rate variation (HRV) in response to deep breathing and standing, lower body negative pressure, isometric handgrip, and the cold pressor test were performed by patients with silent (n = 25) and symptomatic (n = 25) ambulatory ischaemia and by controls (n = 21). No difference in parasympathetic efferent function between patients with silent and symptomatic ischaemia was recorded, but both had significantly less HRV in response to standing than the controls (p < 0.005 for silent and p < 0.01 for symptomatic). Patients with silent ischaemia showed an increased propensity for peripheral vasodilatation compared with symptomatic patients (p < 0.02) and controls (p < 0.04). Impaired sympathetic function was found in patients with pure silent ischaemia (n = 4) compared with the remaining patients with silent ischaemia whose pain pathways were presumed to be intact. CONCLUSIONS--Patients with silent ischaemia and pain pathways presumed to be intact have an enhanced peripheral vasodilator response, and if this applied to the coronary vasculature it could provide a mechanism for limiting ischaemia to below the pain threshold. Patients with pure silent ischaemia have evidence of sympathetic autonomic dysfunction. Images PMID:8297687

The clinical significance of silent ischemia is not fully known. The purpose of this study was to determine whether the presence or absence of angina during a thallium stress test positive for ischemia was independently predictive of an adverse outcome. Two hundred thirty-four consecutive patients with ischemia on a thallium stress test were identified. Ischemia was defined as the presence of defect(s) on the immediate postexercise scans not in the distribution of prior infarctions that redistributed on 4-hour scans. During the test 129 patients had angina, defined as characteristic neck, jaw, arm, back or chest discomfort, while the remaining 105 patients had no angina. Follow-up ranged from 2 to 8.2 years (mean 5.2 +/- 2.1) and was successfully obtained in 156 patients. Eighty-two of the 156 patients had angina (group A) and 74 had silent ischemia (group S). Group A patients were significantly older (62 +/- 8 vs 59 +/- 8 years, p less than 0.05). There was no significant difference between the 2 groups in terms of sex, history of prior infarction or presence of left main/3-vessel disease. A larger percentage of patients in group A were receiving beta blockers (60 vs 41%, p less than 0.05) and nitrates (52 vs 36%, 0.05 less than p less than 0.10). There was a large number of cardiac events (myocardial infarction, revascularization and death) in both groups (37 of 82 [45%] in group A; 28 of 72 [38%] in group S) but no statistically significant difference between the groups. Similarly, life-table analysis revealed no difference in mortality between the 2 groups

Recently, silent strokes are more frequently demonstrated by CT and MRI with the advance of neuroimaging. The infarcted lesions unrelated to the neurological symptoms were detected in 8, 30, 28, 34, 60, 63% of the patients with cerebral infarction in 1977-78, 1982, 1985, 1986, 1987, 1988, respectively, by CT and/or MRI, and the asymptomatic patients with incidentally diagnosed cerebral infarction were amounted to 16% (8 of 51 cases) in 1988. Of the recent 50 patients with cerebral infarction examined by CT and MRI, asymptomatic cerebrovascular lesions were detected in 25 (50%) by CT and in 35 (70%) by MRI. MRI also revealed asymptomatic old hemorrhage in 7 (14%). The clinical significance of silent stroke was discussed. (author).

Harmony hurts: participation and silent conflict at an Indonesian fish pond.

Participatory environmental and resource management is premised on open communication to reach consensus. However, deliberate and open communication cannot adequately address silent conflict. This begs two questions. First, how is the existence of covert communication and silent conflict to be recognized and addressed? Second, how are the wider social relations and traditions that encompass communication and conflict to be described and explained? These questions revolve around communicative power. Communication of environmental knowledge is deeply embedded in social power structures, with direct implications for participatory resource planning and implementation. Ethnographic research conducted at a failed community-managed fish farming project in Southeast Sulawesi, Indonesia shows that a culture of harmony and respect for authority can silence environmental conflict in the hierarchical "community." Three propositions are offered. First, communication amnesia and exclusion jeopardize participation. Second, cultures of harmony and silent conflict shape planning processes and outcomes. Third, the weak use manipulation and communication strategy to acquire a "voice" while preserving harmony. These propositions address five unresolved issues in participatory resource management: analysis of groups, contextuality, social relationships, nonparticipants, and informal communication. Power, tradition, and social networks affect the valuing of knowledge relative to the power of different individuals and institutions to communicate priorities, values, and needs. These factors are critical to the inclusion of both participants and nonparticipants.

Left ventricular function abnormalities as a manifestation of silent myocardial ischemia.

Lambert, C R; Conti, C R; Pepine, C J

1986-11-01

A large body of evidence exists indicating that left ventricular dysfunction is a common occurrence in patients with severe coronary artery disease and represents silent or asymptomatic myocardial ischemia. Such dysfunction probably occurs early in the time course of every ischemic episode in patients with coronary artery disease whether symptoms are eventually manifested or not. The pathophysiology of silent versus symptomatic left ventricular dysfunction due to ischemia appears to be identical. Silent ischemia-related left ventricular dysfunction can be documented during spontaneous or stress-induced perturbations in the myocardial oxygen supply/demand ratio. It also may be detected by nitroglycerin-induced improvement in ventricular function or by salutary changes in wall motion following revascularization. Silent left ventricular dysfunction is a very early occurrence during ischemia and precedes electrocardiographic abnormalities. In this light, its existence should always be kept in mind when dealing with patients with ischemic heart disease. It can be hypothesized that because silent ischemia appears to be identical to ischemia with symptoms in a pathophysiologic sense, prognosis and treatment in both cases should be the same.

Recent studies strongly support the prognostic importance of transient silent ischemia. Because patients with silent ischemia are at higher risk of a cardiac event, they are likely to benefit not only from control of symptoms, but also from treatment directed at prevention of ischemia.

Infant VEPs reveal neural correlates of implicit naming: Lateralized differences between lexicalized versus name-unknown pictures

Recent behavioural studies with toddlers have demonstrated that simply viewing a picture in silence triggers a cascade of linguistic processing which activates a representation of the picture’s name (Mani and Plunkett, 2010, 2011). Electrophysiological studies have also shown that viewing a picture modulates the auditory evoked potentials (AEPs) triggered by later speech, from early in the second year of life (Duta et al., 2012; Friedrich and Friederici, 2005; Mani et al., 2011) further supporting the notion that picture viewing gives rise to a representation of the picture’s name against which later speech can be matched. However, little is known about how and when the implicit name arises during picture viewing, or about the electrophysiological activity which supports this linguistic process. We report differences in the visual evoked potentials (VEPs) of fourteen-month-old infants who saw photographs of animals and objects, some of which were name-known (lexicalized), while waiting for an auditory label to be presented. During silent picture viewing, lateralized neural activity was selectively triggered by lexicalized items, as compared to nameless items. Lexicalized items generated a short-lasting negative-going deflection over frontal, left centro-temporal, and left occipital regions shortly after the picture appeared (126–225 ms). A positive deflection was also observed over the right hemisphere (particularly centro-temporal regions) in a later, longer-lasting window (421–720 ms). The lateralization of these differences in the VEP suggests the possible involvement of linguistic processes during picture viewing, and may reflect activity involved in the implicit activation of the picture’s name.

In order to investigate relationship between regional cerebral blood flow (rCBF) and the white matter lesions on MRI in silent cerebral infarction, we quantitatively measured rCBF by 123 I-IMP autoradiography method (IMP ARG method) and single photon emission tomography (SPECT) in 36 patients with silent cerebral infarction (SCI group), 22 patients with multi-infarct dementia (MID group), and 16 control subjects without periventricular hyperintensity (PVH) and lacunar infarction on MRI (CL group). Regions of interest (ROIs) on rCBF images were set in the frontal (F), temporal (T), parietal (P), occipital (O) cortex, and the cerebral white matter (W). The severity of PVH on MRI T 2 -weighted image was divided into four grades (grade 0-3). Though the frequency of hypertension was significantly higher in SCI group and MID group compared with CL group, no significant difference was seen in the mean age among these three groups. rCBF in the white matter and cerebral cortices except the occipital cortex in SCI group was significantly low compared with CL group (rCBF SCI /rCBF CL : W 0.87, F 0.87, T 0.87, P 0.88, O 0.92). rCBF in the white matter and cerebral cortices, especially in the white matter and frontal cortex, in MID group was significantly low compared with SCI group (rCBF MID /rCBF CL : W 0.69, F 0.71, T 0.74, P 0.75, O 0.81). The mean grade of PVH in MID group was significantly higher than that in SCI group (SCI 1.1 vs MID 2.5). The severity of PVH was significantly correlated with each rCBF in the white matter and cerebral cortices, especially in the white matter and frontal cortex. Our findings suggest that the quantitative measurement of rCBF by IMP ARG method is useful for the follow-up study in the patients with silent cerebral infarction as well as the evaluation of the severity of PVH on MRI.

Samarzija, M.; Tezak, S.

1994-01-01

The purpose of this study was to determine the frequency and importance of silent ischemia in patients (pts) after the acute myocardial infarction (A MI) as well as to establish diagnostic and prognostic value of exercise stress test (EST), Holter (H) monitoring and thallium-201 (Tl) scintigraphy. All the three tests were performed 2-4 months following the AMI. The criterion for diagnosing myocardial ischemia on EST and H is 1 mm or more of horizontal or down-sloping ST depression. Additional criteria for Holter imply the ischemic episode should last one minute and be separated from other episodes by at least one minute. Planar thallium images were performed 5-10 minute after the stress test; the delayed images were obtained after 3-6 hours. Visual and quantitative methods were employed in the analysis of TI-scintigraphy. Scintigraphy was considered positive if exercise- induced perfusion defects showed redistribution. The study included 74 asymptomatic patients after the AMI. The patients were divided into two groups by results of quantitative Tl-scintigraphy: Group I - 44 pts with silent ischemia, Group II - 30 pts without ischemia. In Group I, out of 44 pts, 9 had a positive exercise stress, 4 showed a painless ST depression on Holter and 7 had both tests positive, whereas 24 pts had only scintigraphy positive. In Group II one patient had positive EST and H. Sensitivity and specificity were determined by results of coronary arteriography performed on 33 pts: EST (Se=40%, Sp=80%), H (Se=219, Sp=100%) and scintigraphy (Se=93%, Sp =80%). During the follow-up period lasting at least 12 months, in Group I 3 pts died, 1 developed a new myocardial infarction and 15 pts had painful ischemic occurrences. In Group II only 3 pts developed symptoms of angina pectoris. Tl-scintigraphy was the only non-invasive test showing significant correlation with the follow-up outcomes. The diagnostic and prognostic superiority of Tl-scintigraphy justifies its value as the initial

During the past two decades, interest in applying non-equilibrium plasmas to the removal of hazardous chemicals from gaseous media has been growing, in particular from heightened concerns over the pollution of our environment and a growing body of environmental regulations. At the Los Alamos National Laboratory, we are currently engaged in a project to develop non-equilibrium plasma technology for hazardous waste treatment. Our present focus is on dielectric-barrier discharges, which are historically called silent electrical discharges. This type of plasma is also named a silent discharge plasma (SDP). We have chosen this method due to its potential for high energy efficiency, its scientific and technological maturity, and its scalability. The SDP process has been demonstrated to be reliable and economical for the industrial-scale synthesis of ozone, where municipal water treatment plants frequently require the on-site generation of thousands of kilograins per day (Eliasson ampersand Kogelschatz). The related methods of corona processing are presently the focus of work at other institutions, particularly for flue gas processing. Both SDP and corona processes are characterized by the production of large quantities of highly reactive free radicals, especially atomic oxygen O(3P) and the hydroxyl OH, in the gaseous medium and their subsequent reaction with contaminants. Our primary objective is to convert hazardous or toxic chemicals into non-hazardous compounds or into materials which are more amenable to treatment. In the ideal case, the hazardous wastes are destructively oxidized to simpler, non-hazardous compounds plus CO2 and H2O. Sometimes the reaction products are still potentially hazardous, but are easily treated by conventional methods to yield non-hazardous products

2012-01-01

The purpose of this study was to investigate the correlation between platelet aggregability and silent brain infarcts. The study subjects were 445 people (264 men, 181 women; mean age, 53±14 years) with no neurologic signs, history of brain tumor, trauma, cerebrovascular disease, or antiplatelet medications. Adenosine diphosphate (ADP)-induced platelet aggregation was measured by the aggregation-size analytic method. Platelet aggregability was classified into 9 classes. The presence of headache/vertigo, hypertension, diabetes mellitus, hyperlipidemia, or smoking was elicited by questioning or blood sampling. A head MRI scan was performed, and if marked atherosclerosis or obvious stenosis in the intracranial vessels was detected, it was defined as a positive MR angiography (MRA) finding. Silent brain infarcts were detected in 26.3% of subjects. Hyperaggregability defined as that above class 6, 7, and 8 was present in 43.8%, 30.8%, and 15.7% of subjects, respectively. The risk factors for silent brain infarcts by multiple logistic regression analysis were aging, hypertension, positive MRA findings, and hyperaggregability. Platelet ADP hyperaggregability might be a risk factor for silent brain infarcts. (author)

Silent (painless) thyroiditis. Evidence of a geographic variation in frequency

Recent reports suggest that 14% to 23% of thyrotoxic patients have silent (painless) thyroiditis, a newly described syndrome characterized by transient thyrotoxicosis with a low radioactive iodine uptake. A three-year review at a Brooklyn (NY) hospital showed only one definite and three possible cases of silent thyroiditis among 86 thyrotoxic patients. At most, 4% to 5% of thyrotoxic patients had silent thyroiditis. The authors suggest a geographic variation in this syndrome. Most cases and the largest series are from Japan and the Great Lakes area of North America. The latter may be related to increased iodine intake over many years in a previously endemic area of hypoiodidism and goiter, although other local factors may also be involved.

Full Text Available The aim of this study is to examine different preferences for brand name–country of origin shaped in line with levels of conspicuous consumption tendency and to determine Turkish consumers’ preferences for brand name–country of origin combinations in different product groups. The study was conducted in Eskisehir (Turkey with a sample of 413 people chosen through convenience sampling. The study data were collected with a questionnaire and face-face-to interviews. The participants’ preferences for brand name-country of origin combinations were determined separately based on four different product groups(hedonic, utilitarian, durable and non-durable. The study showed that, for all the four product groups, the participants preferred the products with a Turkish brand name and Turkey as the country of origin most, followed by the products with a French brand name and France as the country of origin. This finding suggests that, with respect to the four product groups in the study, Turkish consumers preferred domestic products over foreign products. Also, the participants who preferred French brand name-France as the country of origin for the hedonic product, French brand name-Turkey as the country of origin for the utilitarian product, French brand name-Turkey as the country of origin for the durable product and French brand name-France as the country of origin for the non-durable product were found to have highest tendency of conspicuous consumption in the corresponding product groups. In other words, as the level of conspicuous consumption increased, the participants tended to prefer French brand name-France as the country of origin for the hedonic product, French brand name-Turkey as the country of origin for the utilitarian product, French brand name-Turkey as the country of origin for the durable product and French brand name-France as the country of origin for the non-durable product.

Population-based studies have shown a heightened prevalence of clinically silent brain infarcts in subjects who have migraine with aura (MA). We sought to determine whether this association could be confirmed in young patients with cryptogenic ischemic stroke, and explored the role of patent foramen ovale (PFO) as a potential underlying mechanism. Patients were selected from a registry of young patients consecutively treated for ischemic stroke in a tertiary university hospital among those without definite cause of stroke. Patients with PFO were matched for age and gender with patients with normal atrial septum. Migraine and MA were evaluated after patient selection and matching. Silent brain infarcts were independently evaluated on MRI. We included 100 patients [60 men; mean age (SD), 44.8 years (8.3)], 50 patients with PFO. We found silent brain infarcts in 36 patients and MA in 13 patients. MA was more frequent in patients with silent brain infarcts than in patients without silent brain infarcts (25.0% vs. 6.3%; OR, 5; 95% CI, 1.4-17.6; P = 0.01). Traditional cardiovascular risk factors were not associated with silent brain infarcts. PFO was neither associated with MA (OR, 1.7; 95% CI, 0.5-5.3) nor silent brain infarcts (OR, 0.7; 95% CI, 0.3-1.5). The association of MA with silent brain infarcts was not altered after adjustment for PFO. Findings suggest that silent brain infarcts in young patients with cryptogenic stroke is associated with MA. We found no evidence for a mediating effect of PFO on this association. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

Distinct transmitter release properties determine differences in short-term plasticity at functional and silent synapses.

Science.gov (United States)

Cabezas, Carolina; Buño, Washington

2006-05-01

Recent evidence suggests that functional and silent synapses are not only postsynaptically different but also presynaptically distinct. The presynaptic differences may be of functional importance in memory formation because a proposed mechanism for long-term potentiation is the conversion of silent synapses into functional ones. However, there is little direct experimentally evidence of these differences. We have investigated the transmitter release properties of functional and silent Schaffer collateral synapses and show that on the average functional synapses displayed a lower percentage of failures and higher excitatory postsynaptic current (EPSC) amplitudes than silent synapses at +60 mV. Moreover, functional but not silent synapses show paired-pulse facilitation (PPF) at +60 mV and thus presynaptic short-term plasticity will be distinct in the two types of synapse. We examined whether intraterminal endoplasmic reticulum Ca2+ stores influenced the release properties of these synapses. Ryanodine (100 microM) and thapsigargin (1 microM) increased the percentage of failures and decreased both the EPSC amplitude and PPF in functional synapses. Caffeine (10 mM) had the opposite effects. In contrast, silent synapses were insensitive to both ryanodine and caffeine. Hence we have identified differences in the release properties of functional and silent synapses, suggesting that synaptic terminals of functional synapses express regulatory molecular mechanisms that are absent in silent synapses.

The written voice: implicit memory effects of voice characteristics following silent reading and auditory presentation.

Science.gov (United States)

Abramson, Marianne

2007-12-01

After being familiarized with two voices, either implicit (auditory lexical decision) or explicit memory (auditory recognition) for words from silently read sentences was assessed among 32 men and 32 women volunteers. In the silently read sentences, the sex of speaker was implied in the initial words, e.g., "He said, ..." or "She said...". Tone in question versus statement was also manipulated by appropriate punctuation. Auditory lexical decision priming was found for sex- and tone-consistent items following silent reading, but only up to 5 min. after silent reading. In a second study, similar lexical decision priming was found following listening to the sentences, although these effects remained reliable after a 2-day delay. The effect sizes for lexical decision priming showed that tone-consistency and sex-consistency were strong following both silent reading and listening 5 min. after studying. These results suggest that readers create episodic traces of text from auditory images of silently read sentences as they do during listening.

Methods: a cross-sectional descriptive study of 79 asymptomatic patients suffering type 2 diabetes mellitus and without a history of ischemic cardiopathy, blood hypertension or smoking. These patients were seen at the endocrinology service of "Dr Carlos J. Finlay" from February 2009 to February 2011. They underwent Doppler tissue imaging echocardiography and their levels of glycemia on fasting, pospandrial glycemia, glycated haemoglobin, cholesterol and triglycerides were determined. The analyzed clinical variables lfor the silent myocardial ischemia were age, sex, time of evolution of diabetes and body mass index. Frequency distributions and percentage estimations were used for the qualitative variables whereas the Chi square test served to establish relationships among variables. Results: the average age of the patients was 54 years, 69.1 % were males and 31.9 % females. The Doppler tissue imaging echocardiography showed signs of myocardial ischemia in 20 % of these patients, and 75 % had pathological levels of total cholesterol with statistically significant relation (p=0.01 and their relative risk of developing myocardial ischemia was 4.4 times higher than the rest of patients with normal cholesterol. The values of glycemia on fasting, pospandrial glycemia and glycated haemoglobin were significantly higher than in the ischemic group. The patients having significantly higher values of glycemia on fasting exhibited a risk of myocardial ischemia that was 10.5 times higher than that of the patients with adequate values for this variable. Likewise, the risk of getting sick was 12 times higher in those cases with high values of pospandrial glycemia. Conclusions: silent myocardial ischemia is frequent in type 2 diabetes mellitus patients and is associated with

What's in and what's out in branding? A novel articulation effect for brand names.

Topolinski, Sascha; Zürn, Michael; Schneider, Iris K

2015-01-01

The present approach exploits the biomechanical connection between articulation and ingestion-related mouth movements to introduce a novel psychological principle of brand name design. We constructed brand names for diverse products with consonantal stricture spots either from the front to the rear of the mouth, thus inwards (e.g., BODIKA), or from the rear to the front, thus outwards (e.g., KODIBA). These muscle dynamics resemble the oral kinematics during either ingestion (inwards), which feels positive, or expectoration (outwards), which feels negative. In 7 experiments (total N = 1261), participants liked products with inward names more than products with outward names (Experiment 1), reported higher purchase intentions (Experiment 2), and higher willingness-to-pay (Experiments 3a-3c, 4, 5), with the price gain amounting to 4-13% of the average estimated product value. These effects occurred across English and German language, under silent reading, for both edible and non-edible products, and even in the presence of a much stronger price determinant, namely fair-trade production (Experiment 5).

White, Andrew A; Bosso, John V; Stevenson, Donald D

2013-01-01

Aspirin desensitization is a treatment option for patients with aspirin-exacerbated respiratory disease (AERD). Some patients with an excellent history of aspirin or nonsteroidal anti-inflammatory drug (NSAID) reactions have negative aspirin challenges/desensitization. This study discusses the clinical entity of silent desensitization in AERD and the dilemma that this presents to the practicing allergist/immunologist. We discuss a series of patients with a strong history of NSAID reactions who initially underwent a negative challenge/silent desensitization. These patients were subsequently proven to have AERD after a second positive aspirin challenge. Silent desensitization is an uncommon but important outcome to recognize in AERD. Clinicians performing aspirin desensitization should understand that this can occur and consider a second confirmatory aspirin challenge in some patients.

Silent myocardial ischemia is a major cause of morbidity and mortality in diabetic patients. Its diagnosis by noninvasive means such as myocardial SPECT would improve the management of these patients. The purpose of this study is to assess the frequency of silent myocardial ischemia in asymptomatic diabetics and their evolution. As a result, the myocardial SPECT is a reliable tool for screening for silent myocardial ischemia in diabetic patients. Its prognostic value allows to stratify the cardiac risk and guide therapeutic management. Its integration into a screening strategy in Tunisia seems limited by its low availability and cost. The latter could be reduced by better patient selection.

Silent Thyroiditis

Walker, Peter

1984-01-01

Silent or painless thyroiditis is a frequent cause of transient hyperthyroidism, which is characterized by recent onset of symptoms in a patient with a normal to modestly enlarged and firm thyroid gland. The hallmarks of the disease are the absence of thyroidal pain or tenderness and a markedly reduced radioiodine uptake. Histologically, the gland is characterized by an important lymphocytic infiltration, occasionally to the point of lymphoid follicle formation. However, other indices of an autoimmune cause are usually absent. The disease appears to have a predilection for the postpartum period. Relapses may occur with subsequent pregnancies. Otherwise, the course is usually benign and transient, requiring moderate doses of β-adrenergic blocking agents for symptomatic relief. No pathogenetic factors are known, but the disease may conceivably have an autoimmune basis, particularly in the postpartum patient. PMID:21278944

Fifty-four asymptomatic patients with positive thallium exercise tests underwent coronary angiography followed by coronary angioplasty (PTCA), as the primary therapy for silent ischemia. The procedure was technically successful in 89% of these patients. Emergency bypass graft surgery was necessary in 2 (3.6%) and q-wave myocardial infarction occurred in 1 (1.8%) of these. All fifty-four patients have been followed for a mean of 35 months since angioplasty. Of the 48 patients with initially successful PTCA, 12 had either clinical restenosis (9/14 or 19%) or a new lesion (3/48 or 6%) during follow-up, which required a repeat PTCA. At the longest follow-up, 46 (85%) had been successfully treated with on or more PTCA procedures. Two patients (3.6%) had sustained late q-wave myocardial infarction and two additional patients reported angina pectoris. There were no deaths. Angioplasty as a primary therapy for silent ischemia appears efficacious, with success and restenosis rates comparable to those in the symptomatic population. Event-free survival is improved, compared with natural history data for patients with silent ischemia from other studies. Prudent risk/benefit analysis may help to define subgroups most likely to benefit from this intervention

2015-05-01

Full Text Available The present approach exploits the biomechanical connection between articulation and ingestion-related mouth movements to introduce a novel psychological principle of brand name design. We constructed brand names for diverse products with consonantal stricture spots either from the front to the rear of the mouth, thus inwards (e.g., BODIKA, or from the rear to the front, thus outwards (e.g., KODIBA. These muscle dynamics resemble the oral kinematics during either ingestion (inwards, which feels positive, or expectoration (outwards, which feels negative. In 7 experiments (total N = 1261, participants liked products with inward names more than products with outward names (Experiment 1, reported higher purchase intentions (Experiment 2, and higher willingness-to-pay (Experiments 3a-3c, 4, 5, with the price gain amounting to 4 % to 13 % of the average estimated product value. These effects occurred across English and German language, under silent reading, for both edible and non-edible products, and even in the presence of a much stronger price determinant, namely fair-trade production (Experiment 5.

Full Text Available Abstract. The degree of immunity to polioviruses of three serotypes among children of different ages was analysed on certain "controlled" and "silent" territories of Russia in different periods of Polio Eradication Initiative. It was shown that the levels of immunity of children’s population to polioviruses on "controlled" and "silent" territories had no significant difference. It was stated that on the phase which preceded the certification for the absence of circulation of wild polioviruses, when the National Immunisation Days were conducted in the country, the percentage of eronegative children to polioviruses of different serotypes was low on all the territories of Russia. After Russia as a part of the WHO European region was certified as a polio free country and mass immunisation was stopped thepercentage of seronegative children increased, especially to poliovirus of serotype 3, both on the "controlled" and on the "silent" territories.

Improvement of ozone yield by a multi-discharge type ozonizer using superposition of silent discharge plasma

International Nuclear Information System (INIS)

Song, Hyun-Jig; Chun, Byung-Joon; Lee, Kwang-Sik

2004-01-01

In order to improve ozone generation, we experimentally investigated the silent discharge plasma and ozone generation characteristics of a multi-discharge type ozonizer. Ozone in a multi-discharge type ozonizer is generated by superposition of a silent discharge plasma, which is simultaneously generated in separated discharge spaces. A multi-discharge type ozonizer is composed of three different kinds of superposed silent discharge type ozonizers, depending on the method of applying power to each electrode. We observed that the discharge period of the current pulse for a multi discharge type ozonizer can be longer than that of silent discharge type ozonizer with two electrodes and one gap. Hence, ozone generation is improved up to 17185 ppm and 783 g/kwh in the case of the superposed silent discharge type ozonizer for which an AC high voltages with a 180 .deg. phase difference were applied to the internal electrode and the external electrode, respectively, with the central electrode being grounded.

Assessing reading fluency in Kenya: Oral or silent assessment?

Science.gov (United States)

Piper, Benjamin; Zuilkowski, Stephanie Simmons

2015-04-01

In recent years, the Education for All movement has focused more intensely on the quality of education, rather than simply provision. Many recent and current education quality interventions focus on literacy, which is the core skill required for further academic success. Despite this focus on the quality of literacy instruction in developing countries, little rigorous research has been conducted on critical issues of assessment. This analysis, which uses data from the Primary Math and Reading Initiative (PRIMR) in Kenya, aims to begin filling this gap by addressing a key assessment issue - should literacy assessments in Kenya be administered orally or silently? The authors compared second-grade students' scores on oral and silent reading tasks of the Early Grade Reading Assessment (EGRA) in Kiswahili and English, and found no statistically significant differences in either language. They did, however, find oral reading rates to be more strongly related to reading comprehension scores. Oral assessment has another benefit for programme evaluators - it allows for the collection of data on student errors, and therefore the calculation of words read correctly per minute, as opposed to simply words read per minute. The authors therefore recommend that, in Kenya and in similar contexts, student reading fluency be assessed via oral rather than silent assessment.

Neocortical inhibitory activities and long-range afferents contribute to the synchronous onset of silent states of the neocortical slow oscillation.

Lemieux, Maxime; Chauvette, Sylvain; Timofeev, Igor

2015-02-01

During slow-wave sleep, neurons of the thalamocortical network are engaged in a slow oscillation (<1 Hz), which consists of an alternation between the active and the silent states. Several studies have provided insights on the transition from the silent, which are essentially periods of disfacilitation, to the active states. However, the conditions leading to the synchronous onset of the silent state remain elusive. We hypothesized that a synchronous input to local inhibitory neurons could contribute to the transition to the silent state in the cat suprasylvian gyrus during natural sleep and under ketamine-xylazine anesthesia. After partial and complete deafferentation of the cortex, we found that the silent state onset was more variable among remote sites. We found that the transition to the silent state was preceded by a reduction in excitatory postsynaptic potentials and firing probability in cortical neurons. We tested the impact of chloride-mediated inhibition in the silent-state onset. We uncovered a long-duration (100-300 ms) inhibitory barrage occurring about 250 ms before the silent state onset in 3-6% of neurons during anesthesia and in 12-15% of cases during natural sleep. These inhibitory activities caused a decrease in cortical firing that reduced the excitatory drive in the neocortical network. That chain reaction of disfacilitation ends up on the silent state. Electrical stimuli could trigger a network silent state with a maximal efficacy in deep cortical layers. We conclude that long-range afferents to the neocortex and chloride-mediated inhibition play a role in the initiation of the silent state. Copyright © 2015 the American Physiological Society.

Immunological profile of silent brain infarction and lacunar stroke.

Directory of Open Access Journals (Sweden)

Paola Sarchielli

Full Text Available Neuroinflammation is believed to be involved in the pathophysiological mechanisms of silent brain infarcts (SBI. However, the immunological profile of SBI has been scarcely investigated. In the context of a national research project named SILENCE, aimed at investigating clinical, biochemical and pathogenic features of SBI, we have measured the plasma profile of some inflammatory-related molecules in SBI patients (n = 21, patients with recent lacunar infarcts (LI, n = 28 and healthy controls (n = 31, consecutively enrolled in four Italian centres. A panel of chemokines (MIG, CTACK, IL16, SDF1a, MCP1, growth factors (SCF, SCGFb, HGF, IL3, immunoglobulin-type adhesion molecules (ICAM1, VCAM1, proinflammatory cytokines (IL18, INFa2, MIF, IL12p40, cell surface receptors on T-cells (IL2Ra, and inductors of apoptosis (TRAIL was assessed in plasma samples by Luminex xMAP™ technology. Immunological parameters were compared using non-parametric statistics and performance to distinguish SBI and LI was evaluated by receiver operating characteristic (ROC analysis. Plasma levels of ICAM1 were significantly higher in both SBI and LI patients as compared to controls (SBI≥LI>Ctrl. A different trend was observed for IL16 (SBICtrl, SCF (LICtrl and SCGFb (SBI>LICtrl and IL18 when compared to LI patients (Ctrl≤SBI>LI. All the other immunological markers did not significantly differ among groups. According to ROC analysis, the best predictor for SBI condition was the chemokine MIG (AUC = 0.84, sensitivity 86%, specificity 77%, while SCF had the best performance in distinguishing LI patients (AUC = 0.84, sensitivity 86%, specificity 68%. These results confirm the involvement of inflammatory processes in cerebrovascular disorders, particularly in SBI, a very common age-related condition. The differences in plasma profile of inflammatory molecules may underlie different pathological mechanisms in SBI and LI patients.

Silent somatotroph tumours are growth hormone (GH) immunoreactive (IR) pituitary tumours without clinical and biological signs of acromegaly. Their better characterisation is required to improve the diagnosis. Twenty-one silent somatotroph tumours were compared to 59 somatotroph tumours with acromegaly. Tumours in each group were classified into GH and plurihormonal (GH/prolactin (PRL)/±thyroid-stimulating hormone (TSH)) and into densely granulated (DG) and sparsely granulated (SG) types. The two groups were then compared with regards to proliferation (Ki-67, p53 indexes and mitotic count), differentiation (expression of somatostatin receptors SSTR 2A -SSTR 5 and transcription factor Pit-1) and secretory activity (% of GH- and PRL-IR cells). The silent somatotroph tumours represented 2% of all tested pituitary tumours combined. They were more frequent in women than in men (P = 0.002), more frequently plurihormonal and SG (P acromegaly. They all expressed SSTR 2A , SSTR 5 and Pit-1. The plurihormonal (GH/PRL/±TSH) tumours were mostly observed in women (sex ratio: 3/1) and in patients who were generally younger than those with acromegaly (P acromegaly. A low secretory activity of these tumours might explain the normal plasma values for GH and insulin-like growth factor 1 (IGF1) and the absence of clinical signs of acromegaly. © 2017 European Society of Endocrinology.

Full Text Available Packaging which is often called as the ‘silent salesman’ is an important component of marketing. Today the importance of packaging has risen to such an extent that product packaging is rightly called as the fifth ‘P’ of marketing mix. FMCG are products which are utilized by large number of people. The present study examined the discriminating power of five selected FMCG packaging variables namely ‘picture’, ‘colour’, ‘size’, ‘shape’ and ‘material’ amidst those who purchased FMCG based on these packaging variables and for those who purchased FMCG not based on these packaging variables. Descriptive research was carried out in the study. Respondents (students were asked to rate four packaging variable on a five point Likert’s scale. Discriminant analysis showed that only two variables namely ‘Colour’ (.706 and ‘Shape’ (–.527 were good predictors. Variables ‘Picture’, ‘size’ and ‘material’ were considered as poor predictors as far as the student communities were considered. The cross validated classification showed that out of the 240 samples drawn, 91.8% of the cases were correctly classified.

High-field MR scans have often showed patchy incidental findings especially in the elderly. We examined 91 patients, without episodes of cerebrovascular disorders previously, who had silent cerebral lesions noted by the 1.5 tesla superconductive system T2 weighted magnetic resonance imaging. They were divided into three subtypes by the localization of foci. The 23 subjects (25%) showed confined lesions to thalamus and/or internal capsule and/or basal ganglia (the basal ganglia type). The 39 subjects (43%) had lesions predominantly in cerebral cortex and/or subcortical white matter and/or cerebellum (the diffuse subcortical type). Finally, the 29 subjects (32%) had both features of abovementioned two groups (the mixed type). These subtypes were correlated with age, sex and some of the other risk factors, such as systolic blood pressure, diastolic blood pressure, serum total cholesterol and uric acid, for stroke. From the age extent and the correlation of subtypes to risk factors, the basal ganglia type was suspected to be based on the different origin from other two types. The authors proposed that the arteriosclerotic factor might play an important role in the incidence of the diffuse subcortical type and the mixed type silent cerebral infarctions and that the hemodynamic factor might play an important role in the incidence of the basal ganglia type.

Given evidence that ischemic heart disease is the most frequent cause of death in patients with cerebrovascular disease, we used ergometrics to screen 80 patients with TIA for silent myocardial ischemia (SMI) at the neurological unit of Hospital Clínico Universitario in Zaragoza, Spain. The patients were compared with a control group of 80 with no signs of heart disease. Neither the patients nor the controls had ever shown clinical signs of coronary ischemia and their baseline electrocardiograms were normal. Stress test results were positive in 25 (31%) of the TIA patients, and in 4 (5%) (p Hiperlipidemia (75% testing positive versus 43% negative, p < 0.01) and diabetes (31% testing positive versus 13% negative, p < 0.01) were the risk factors statistically related with a positive stress test.

Deafening silence? Time to reconsider whether organisations are silent or deaf when things go wrong.

Science.gov (United States)

Jones, Aled; Kelly, Daniel

2014-09-01

Several public inquiries into healthcare failings in the UK have noted that employees of failing organizations attempt to raise concerns about shortcomings in care, often over a prolonged period of time, only for those concerns to be ignored. However, healthcare literature has largely focused on how organizations and their employees are silent in the face of such failings, positioning employees as daring not to speak in response to serious workplace problems or issues. We argue that only focussing on organizational silence is a critical mistake which misrepresents actual events and overly-simplifies the complexities of workplace culture. The disregard shown by academics, practitioners and policy makers to employee voice strategies, which do not amount to whistle-blowing, but equally cannot either be defined as "silence", results in signals being ignored that can be effective in preventing and ending wrongdoing by others. In addition to understanding silence we suggest therefore that better understanding of why organizations are deaf to, or disregard, employee concerns are needed. We propose that a virtuous cycle is possible, whereby the introduction of systems that result in better listening and valuing of employee concerns reinforces a culture of speaking up and, in turn, organizational learning. Similarly, organizations that disregard employees concerns are destined not to learn, ultimately falling silent and failing. Published by the BMJ Publishing Group Limited.

Silent Bodies: Japanese taciturnity and image thinking

Directory of Open Access Journals (Sweden)

Ana Došen

2017-03-01

Full Text Available A nonverbal transmission and an implicit way of communication are highly encouraged in Japanese society. The reason for this “silence prerogative” is often found in historical facts of lengthy feudal era or in ancient philosophies and religions such as Buddhism and Confucianism and their various concepts which privilege taciturn way of communication. Moreover, the unspoken comprehension is often complemented by the attitude which equates truthfulness with silence. This paper explores the silence as a communicative act in the domain of Japanese art, where the body takes over the place of the language. In traditional Japanese theatrical performance, such as noh, words are often inadequate to convey emotion and therefore the aesthetics of emptiness, understatement and abstraction is transcended by the masks with "nonmoving lips". Drawing on theoretical perspectives from both East and West, I argue that the silent bodies operate as deliberate and integral determinants of Japanese non-silent art forms – especially in cinema and theatre. In the Eastern thought, visual perception is fundamental in cognition of the world, whereas auditory discernment is secondary to "image-thinking" (Yuasa. Accustomed to taciturnity, Japanese audience effectively corresponds to the performance and "completes" it in silence.

Silent embolic cerebral infarction (SECI) is a major complication of coronary angiography (CAG) and percutaneous coronary intervention (PCI). Patients with stable coronary artery disease (CAD) who underwent CAG with or without PCI were recruited. Cerebral diffusion-weighted magnetic resonance imaging was performed for SECI within 24 hours. Clinical and angiographic characteristics were compared between patients with and without SECI. Silent embolic cerebral infarction occurred in 12 (12%) of the 101 patients. Age, total cholesterol, SYNTAX score (SS), and coronary artery bypass history were greater in the SECI(+) group (65 ± 10 vs 58 ± 11 years,P= .037; 223 ± 85 vs 173 ± 80 mg/dL,P= .048; 30.1 ± 2 vs 15 ± 3,PSECI was more common in the PCI group (8/24 vs 4/77,P= .01). On subanalysis, the SS was significantly higher in the SECI(+) patients in both the CAG and the PCI groups (29.3 ± 1.9 vs 15 ± 3,PSECI after CAG and PCI increases with the complexity of CAD (represented by the SS). The SS is a predictor of the risk of SECI, a complication that should be considered more often after CAG. © The Author(s) 2015.

Hyperthyroidism is a risk factor for reduced bone mineral density (BMD) and osteoporotic fractures. Vertebral fracture assessment (VFA) by dual-energy X-ray absorptiometry (DXA) is a radiological method of visualization of the spine, which enables patient comfort and reduced radiation exposure. This study was carried out to evaluate BMD and the prevalence of silent vertebral fractures in young men with hyperthyroidism. We conducted a cross-sectional study in a group of Portuguese men aged up to 50 years and matched in hyperthyroidism (n=24) and control (n=24) groups. A group of 48 Portuguese men aged up to 50 years was divided and matched in hyperthyroidism (n=24) and control (n=24) groups. BMD (g/cm(2)) at L1-L4, hip, radius 33%, and whole body as well as the total body masses (kg) were studied by DXA. VFA was used to detect fractures and those were classified by Genant's semiquantitative method. No patient had previously been treated for hyperthyroidism, osteoporosis, or low bone mass. Adequate statistical tests were used. The mean age, height, and total fat mass were similar in both groups (P≥0.05). The total lean body mass and the mean BMD at lumbar spine, hip, and whole body were significantly decreased in the hyperthyroidism group. In this group, there was also a trend for an increased prevalence of reduced BMD/osteoporosis and osteoporotic vertebral fractures. The results obtained using VFA technology (confirmed by X-ray) suggest that the BMD changes in young men with nontreated hyperthyroidism may lead to the development of osteoporosis and vertebral fractures. This supports the pertinence of using VFA in the routine of osteoporosis assessment to detect silent fractures precociously and consider early treatment. © 2015 European Society of Endocrinology.

Anamnesis and the Silent Narrator in Plato and John

Directory of Open Access Journals (Sweden)

George L. Parsenios

2017-03-01

Full Text Available The Gospel of John is often compared to the dialogues of Plato by those who connect Johannine theology and Platonic philosophy. The comparison operates on the level of ideas. The present paper does not ignore issues of theology and philosophy but grounds a comparison of John and Plato first and foremost on the literary level. In several key places in John 1, 3, and 14, the Johannine narrator recedes from view and is unexpectedly silent where one would expect a narrator’s comment to organize the conversations and interactions between characters in John. Plato also renders the voice of the narrator silent in a dialogue like the Theaetetus. This paper argues that John and Plato both suppress the narrator’s voice in order to further their anamnetic efforts and to make later generations not only readers but participants in their original conversations.

Clinical study of correlation of pre-senile and senile depressive stage with silent cerebral infarction

The relationship between the pre-senile/senile depressive state and silent cerebral infarction was examined by MRI. Consecutive 56 depressive patients aged 50 years or older underwnt MRI. MRI revealed silent cerebral infarction in 60.3% of patients in whom depression occurred at the age of less than 65 years. The complication rate was significantly higher in these patients than the younger patients (60.9% vs 20%). Complications of silent cerebral infarction were found in 53.6% for patients in whom depression occurred at the age of less than 65 years and symptoms were deteriorated at the age of 65 years or older and in 100% for patients in whom it occurred at the age of 65 years or older and hospitalization was simultaneously required. These figures were remarkably higher than the age-related complication rate of silent cerebral infarction in non-depressive normal persons. This suggested that approximately half of depressive patients of pre-senile onset and majority of depressive patients of senile onset might have parenchymal involvement due to silent cerebral infarction. Both perforating-type and cortical-type infarcts were found. This has a implication for the involvement of multiple infarct-related foci in depressive state. For cortical-type infarcts, partial lesions were predominant, followed by frontal and temporal lesions. The incidence of left frontal infarcts was significanly higher than that of right frontal infarcts. Infarcts in both the parietal and left frontal lobes may be responsible for depressive state.

2012-01-01

We assessed teacher-child relations with respect to children's name calls, instructions, and compliance in a preschool classroom. The most frequent consequence to a child's name being called was the provision of instructions. We also observed a higher probability of compliance when children attended to a name call. Next, we evaluated the effects…

One of the strongest predictors of the speed with which adults can name a pictured object is the age at which the object and its name are first learned. Age of acquisition also predicts the retention or loss of individual words following brain damage in conditions like aphasia and Alzheimer's disease. Functional Magnetic Resonance Imaging (fMRI) was used to reveal brain areas differentially involved in naming objects with early or late acquired names. A baseline task involved passive viewing of non-objects. The comparison between the silent object naming conditions (early and late) with baseline showed significant activation in frontal, parietal and mediotemporal regions bilaterally and in the lingual and fusiform gyri on the left. Direct comparison of early and late items identified clusters with significantly greater activation for early acquired items at the occipital poles (in the posterior parts of the middle occipital gyri) and at the left temporal pole. In contrast, the left middle occipital and fusiform gyri showed significantly greater activation for late than early acquired items. We propose that greater activation to early than late objects at the occipital poles and at the left temporal pole reflects the more detailed visual and semantic representations of early than late acquired items. We propose that greater activation to late than early objects in the left middle occipital and fusiform gyri occurs because those areas are involved in mapping visual onto semantic representations, which is more difficult, and demands more resource, for late than for early items.

Detecting Silent Data Corruptions in Aerospace-Based Computing Using Program Invariants

Full Text Available Soft error caused by single event upset has been a severe challenge to aerospace-based computing. Silent data corruption (SDC is one of the results incurred by soft error. SDC occurs when a program generates erroneous output with no indications. SDC is the most insidious type of results and very difficult to detect. To address this problem, we design and implement an invariant-based system called Radish. Invariants describe certain properties of a program; for example, the value of a variable equals a constant. Radish first extracts invariants at key program points and converts invariants into assertions. It then hardens the program by inserting the assertions into the source code. When a soft error occurs, assertions will be found to be false at run time and warn the users of soft error. To increase the coverage of SDC, we further propose an extension of Radish, named Radish_D, which applies software-based instruction duplication mechanism to protect the uncovered code sections. Experiments using architectural fault injections show that Radish achieves high SDC coverage with very low overhead. Furthermore, Radish_D provides higher SDC coverage than that of either Radish or pure instruction duplication.

Detecting Silent Data Corruption for Extreme-Scale Applications through Data Mining

Supercomputers allow scientists to study natural phenomena by means of computer simulations. Next-generation machines are expected to have more components and, at the same time, consume several times less energy per operation. These trends are pushing supercomputer construction to the limits of miniaturization and energy-saving strategies. Consequently, the number of soft errors is expected to increase dramatically in the coming years. While mechanisms are in place to correct or at least detect some soft errors, a significant percentage of those errors pass unnoticed by the hardware. Such silent errors are extremely damaging because they can make applications silently produce wrong results. In this work we propose a technique that leverages certain properties of high-performance computing applications in order to detect silent errors at the application level. Our technique detects corruption solely based on the behavior of the application datasets and is completely application-agnostic. We propose multiple corruption detectors, and we couple them to work together in a fashion transparent to the user. We demonstrate that this strategy can detect the majority of the corruptions, while incurring negligible overhead. We show that with the help of these detectors, applications can have up to 80% of coverage against data corruption.

Agreement of the silent partnership – tax and legal consequences of its conclusion and execution

Full Text Available The institution of the silent partnership is not currently regulated by any legal act in the Polish legal system, although its importance in practice is not in doubt. As every action made in the economic sphere and economic execution of the contract is associated with specific effects on the basis of the tax laws. However, due to the lack of statutory regulation of the institution of silent partnership problematic is the question of determining the effects of tax legislation. Therefore, special attention is needed to determine the issue of these effects on the basis of income tax, tax on goods and services, transfer tax and the tax on inheritance and donations, as well as the question of liability for the tax liabilities of the silent partnership.

Measuring the prevalence of regional mutation rates: an analysis of silent substitutions in mammals, fungi, and insects

Directory of Open Access Journals (Sweden)

Tuch Brian B

2008-06-01

Full Text Available Abstract Background The patterns of mutation vary both within and across genomes. It has been shown for a few mammals that mutation rates vary within the genome, while for unknown reasons, the sensu stricto yeasts have uniform rates instead. The generality of these observations has been unknown. Here we examine silent site substitutions in a more expansive set (20 mammals, 27 fungi, 4 insects to determine why some genomes demonstrate this mosaic distribution and why others are uniform. Results We applied several intragene and intergene correlation tests to measure regional substitution patterns. Assuming that silent sites are a reasonable approximation to neutrally mutating sequence, our results show that all multicellular eukaryotes exhibit mutational heterogeneity. In striking contrast, all fungi are mutationally uniform – with the exception of three Candida species: C. albicans, C. dubliniensis, and C. tropicalis. We speculate that aspects of replication timing may be responsible for distinguishing these species. Our analysis also reveals classes of genes whose silent sites behave anomalously with respect to the mutational background in many species, indicating prevalent selective pressures. Genes associated with nucleotide binding or gene regulation have consistently low silent substitution rates in every mammalian species, as well as multiple fungi. On the other hand, receptor genes repeatedly exhibit high silent substitution rates, suggesting they have been influenced by diversifying selection. Conclusion Our findings provide a framework for understanding the regional mutational properties of eukaryotes, revealing a sharp difference between fungi and multicellular species. They also elucidate common selective pressures acting on eukaryotic silent sites, with frequent evidence for both purifying and diversifying selection.

2014-08-01

The aim of our study is to investigate the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in the lower limbs and to evaluate the associated risk factors. A total of 322 patients with acute deep venous thrombosis confirmed by CT venography or Doppler ultrasonography were studied. The diagnosis of silent pulmonary embolism was established by computed tomography pulmonary arteriography (CTPA). The association between covariates and the prevalence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs were assessed using chi-square test and multivariable regression. The incidence of silent pulmonary embolism was 33.5% (108 in 322 patients) in all patients with deep venous thrombosis in lower limbs. Chi-square test showed male gender, the right lower limb, proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases were related to a higher incidence of silent pulmonary embolism in patients with deep venous thrombosis in lower limbs. The multivariate regression analysis confirmed that the risk factors associated with silent pulmonary embolism in deep venous thrombosis patients included the right side and proximal location of the thrombus (odds ratio: 2.023, 95% CI: 1.215-3.368; odds ratio: 3.610, 95% CI: 1.772-7.354), unprovoked venous thrombosis (odds ratio: 2.037, 95% CI: 1.188-3.493), coexisting heart diseases (odds ratio: 4.507, 95% CI: 2.667-7.618). Silent pulmonary embolism occurred frequently in patients with deep venous thrombosis in lower limbs. The right side, the proximal location of the thrombus, unprovoked venous thrombosis and coexisting heart diseases increased the risk for the occurrence of silent pulmonary embolism. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Full Text Available The use of modern technologies has been widely prevalent among language learners, and video, in particular, as a valuable learning tool provides learners with comprehensible input. The present study investigated the effect of silent and freeze-frame viewing techniques of video materials on the intermediate English as a foreign language (EFL learners’ listening comprehension. To this end, 45 intermediate EFL learners participated in this quasi-experimental study. The results of one-way ANOVA revealed that there was a statistically significant difference between the experimental groups (using two types of viewing techniques and the control group. While the difference between the two experimental groups was not statistically significant, the experimental groups outperformed the control group significantly.

Characterisation of silent and active genes for a variable large protein of Borrelia recurrentis

Directory of Open Access Journals (Sweden)

Scragg Ian G

2002-10-01

Full Text Available Abstract Background We report the characterisation of the variable large protein (vlp gene expressed by clinical isolate A1 of Borrelia recurrentis; the agent of the life-threatening disease louse-borne relapsing fever. Methods The major vlp protein of this isolate was characterised and a DNA probe created. Use of this together with standard molecular methods was used to determine the location of the vlp1B. recurrentis A1 gene in both this and other isolates. Results This isolate was found to carry silent and expressed copies of the vlp1B. recurrentis A1 gene on plasmids of 54 kbp and 24 kbp respectively, whereas a different isolate, A17, had only the silent vlp1B. recurrentis A17 on a 54 kbp plasmid. Silent and expressed vlp1 have identical mature protein coding regions but have different 5' regions, both containing different potential lipoprotein leader sequences. Only one form of vlp1 is transcribed in the A1 isolate of B. recurrentis, yet both 5' upstream sequences of this vlp1 gene possess features of bacterial promoters. Conclusion Taken together these results suggest that antigenic variation in B. recurrentis may result from recombination of variable large and small protein genes at the junction between lipoprotein leader sequence and mature protein coding region. However, this hypothetical model needs to be validated by further identification of expressed and silent variant protein genes in other B. recurrentis isolates.

Accuracy of Ultrasonography and Rectal Palpation in the Diagnosis of Silent Heat in Cows Compared to Plasma Progesterone Concentration

Zdunczyk, S.; Janowski, T.; Ras, A.; Baranski, W.

2009-01-01

The study was carried out on five dairy herds in the North-East Poland. The cows, which showed no visible oestrus signs until day 60 postpartum, were examined by ultrasonography and rectal palpation twice, at a 10-d interval. A real-time, B-mode scanner with a 5 MHz probe was used. The plasma progesterone concentration was determined using RIA. A high progesterone level on the first examination, but low on the second, or low on the first and high on the second examination were interpreted as a silent heat. Based on the progesterone values, silent heat was diagnosed in 145 anoestrous cows, whereas ultrasonographically, 106 cows were found to have silent heat. The accuracy of the ultrasonography and rectal palpation in the diagnosis of silent heat in cows was 89.0 % and 69.7 %, respectively (P ≤ 0.05). For the diagnosis of the corpus luteum, the sensitivity and specificity of the ultrasonography was 94.7 % and 84.0 %, and for rectal palpation 86.2 % and 70.3 %, respectively (P ≤ 0.05). Our results showed that ultrasonography is a useful tool in the diagnosis of silent heat in cows. (authors)

To determine an association between sonographically determined contractility with the symptomatic or silent nature of gallstone. Adult gallstone patients without (group I) and with biliary symptoms (group II) were compared with age and gender-matched controls. Demographic data, body mass index, risk factors, size, number and mobility of gallstone, gallbladder wall thickness (GBWT), volume and Ejection Fraction (EF) were determined on ultrasound before and after a standardized fatty meal (BFM and AFM). Demographic data, risk factors and gallstone characteristics were analyzed by Pearson Chi-square test and the gallbladder characteristics were analyzed by One-way ANOVA and Post Hoc tests by multiple comparisons on SPSS 11 with significance p=0.05. The gallbladder contractility as measured by changes in wall thickness and volume changes BFM and AFM, and ejection fraction was similar in controls and asymptomatic cholelithiasis groups and significantly reduced in symptomatic patients (p<.001). Multiparity (p=0.002), female gender (p=0.018), age less than 50 years (0.05), impacted calculi (p=0.001), multiple calculi (<.001) and calculi 5 mm (p<0.001) were associated with pain. A sluggishly emptying gallbladder was more significantly associated with symptomatic cholelithiasis compared to controls and asymptomatic cholelithiasis state in this series. Consideration of age, gender, impaction of calculi, number and size of calculi is important in causing symptom state and management options. (author)

Direct speech quotations promote low relative-clause attachment in silent reading of English.

Science.gov (United States)

Yao, Bo; Scheepers, Christoph

2018-07-01

The implicit prosody hypothesis (Fodor, 1998, 2002) proposes that silent reading coincides with a default, implicit form of prosody to facilitate sentence processing. Recent research demonstrated that a more vivid form of implicit prosody is mentally simulated during silent reading of direct speech quotations (e.g., Mary said, "This dress is beautiful"), with neural and behavioural consequences (e.g., Yao, Belin, & Scheepers, 2011; Yao & Scheepers, 2011). Here, we explored the relation between 'default' and 'simulated' implicit prosody in the context of relative-clause (RC) attachment in English. Apart from confirming a general low RC-attachment preference in both production (Experiment 1) and comprehension (Experiments 2 and 3), we found that during written sentence completion (Experiment 1) or when reading silently (Experiment 2), the low RC-attachment preference was reliably enhanced when the critical sentences were embedded in direct speech quotations as compared to indirect speech or narrative sentences. However, when reading aloud (Experiment 3), direct speech did not enhance the general low RC-attachment preference. The results from Experiments 1 and 2 suggest a quantitative boost to implicit prosody (via auditory perceptual simulation) during silent production/comprehension of direct speech. By contrast, when reading aloud (Experiment 3), prosody becomes equally salient across conditions due to its explicit nature; indirect speech and narrative sentences thus become as susceptible to prosody-induced syntactic biases as direct speech. The present findings suggest a shared cognitive basis between default implicit prosody and simulated implicit prosody, providing a new platform for studying the effects of implicit prosody on sentence processing.

Background: Asymptomatic patients with severe coronary atherosclerosis may have a normal resting electrocardiogram and stress test. Aim: To assess the yield of Gated Single Photon Emission Computer Tomography (SPECT) for the screening of silent myocardial ischemia in type 2 diabetic patients. Material and methods: Electrocardiogram, stress test and gated-SPECT were performed on 102 type 2 diabetic patients aged 60 ± 8 years without cardiovascular symptoms. All subjects were also subjected to a coronary angiography, whose results were used as gold standard. Results: Gated-SPECT showed myocardial ischemia on 26.5% of studied patients. The sensibility, specificity, accuracy, positive predictive value and negative predictive value were 92.3%, 96%, 95%, 88.8%, 97.3%, respectively. In four and six patients ischemia was detected on resting electrocardiogram and stress test, respectively. Eighty percent of patients with doubtful resting electrocardiogram results and 70% with a doubtful stress test had a silent myocardial ischemia detected by gated-SPECT. There was a good agreement between the results of gated-SPECT and coronary angiography (k =0.873). Conclusions: Gated-SPECT was an useful tool for the screening of silent myocardial ischemia

The Rachel Carson Letters and the Making of Silent Spring

Directory of Open Access Journals (Sweden)

John Paull

2013-06-01

Full Text Available Environment, conservation, green, and kindred movements look back to Rachel Carson’s 1962 book Silent Spring as a milestone. The impact of the book, including on government, industry, and civil society, was immediate and substantial, and has been extensively described; however, the provenance of the book has been less thoroughly examined. Using Carson’s personal correspondence, this paper reveals that the primary source for Carson’s book was the extensive evidence and contacts compiled by two biodynamic farmers, Marjorie Spock and Mary T. Richards, of Long Island, New York. Their evidence was compiled for a suite of legal actions (1957-1960 against the U.S. Government and that contested the aerial spraying of dichlorodiphenyltrichloroethane (DDT. During Rudolf Steiner’s lifetime, Spock and Richards both studied at Steiner’s Goetheanum, the headquarters of Anthroposophy, located in Dornach, Switzerland. Spock and Richards were prominent U.S. anthroposophists, and established a biodynamic farm under the tutelage of the leading biodynamics exponent of the time, Dr. Ehrenfried Pfeiffer. When their property was under threat from a government program of DDT spraying, they brought their case, eventually lost it, in the process spent US$100,000, and compiled the evidence that they then shared with Carson, who used it, and their extensive contacts and the trial transcripts, as the primary input for Silent Spring. Carson attributed to Spock, Richards, and Pfeiffer, no credit whatsoever in her book. As a consequence, the organics movement has not received the recognition, that is its due, as the primary impulse for Silent Spring, and it is, itself, unaware of this provenance.

2006-01-15

The cortical silent period (CSP) following transcranial magnetic stimulation (TMS) of the motor cortex can be used to measure intra-cortical inhibition and changes in a number of important pathologies affecting the central nervous system. The main drawback of this technique has been the difficulty in accurately identifying the onset and offset of the cortical silent period leading to inter-observer variability. We developed an automated method based on the cumulative sum (Cusum) technique to improve the determination of the duration and area of the cortical silent period. This was compared with experienced raters and two other automated methods. We showed that the automated Cusum method reliably correlated with the experienced raters for both duration and area of CSP. Compared with the automated methods, the Cusum also showed the strongest correlation with the experienced raters. Our results show the Cusum method to be a simple, graphical and powerful method of detecting low-intensity CSP that can be easily automated using standard software.

Motor balance in developmental stuttering (DS) was investigated with Transcranial Magnetic Stimulation (TMS), with the aim to define novel neural markers of persistent DS in adulthood. Eleven DS adult males were evaluated with TMS on tongue primary motor cortex, compared to 15 matched fluent speakers, in a "state" condition (i.e. stutterers vs. fluent speakers, no overt stuttering). Motor and silent period thresholds (SPT), recruitment curves, and silent period durations were acquired by recording tongue motor evoked potentials. Tongue silent period duration was increased in DS, especially in the left hemisphere (Pstuttering severity. Pre-TMS electromyography data gave overlapping evidence. Findings suggest the existence of a complex intracortical balance in DS tongue primary motor cortex, with a particular interplay between excitatory and inhibitory mechanisms, also in neural substrates related to silent periods. Findings are discussed with respect to functional and structural impairments in stuttering, and are also proposed as novel neural markers of a stuttering "state" in persistent DS, helping to define more focused treatments (e.g. neuro-modulation).

Purpose: The aim of this study was to report on the development of a standardized target and organ-at-risk naming convention for use in radiation therapy and to present the nomenclature for structure naming for interinstitutional data sharing, clinical trial repositories, integrated multi-institutional collaborative databases, and quality control centers. This taxonomy should also enable improved plan benchmarking between clinical institutions and vendors and facilitation of automated treatment plan quality control. Materials and Methods: The Advanced Technology Consortium, Washington University in St. Louis, Radiation Therapy Oncology Group, Dutch Radiation Oncology Society, and the Clinical Trials RT QA Harmonization Group collaborated in creating this new naming convention. The International Commission on Radiation Units and Measurements guidelines have been used to create standardized nomenclature for target volumes (clinical target volume, internal target volume, planning target volume, etc.), organs at risk, and planning organ-at-risk volumes in radiation therapy. The nomenclature also includes rules for specifying laterality and margins for various structures. The naming rules distinguish tumor and nodal planning target volumes, with correspondence to their respective tumor/nodal clinical target volumes. It also provides rules for basic structure naming, as well as an option for more detailed names. Names of nonstandard structures used mainly for plan optimization or evaluation (rings, islands of dose avoidance, islands where additional dose is needed [dose painting]) are identified separately. Results: In addition to its use in 16 ongoing Radiation Therapy Oncology Group advanced technology clinical trial protocols and several new European Organization for Research and Treatment of Cancer protocols, a pilot version of this naming convention has been evaluated using patient data sets with varying treatment sites. All structures in these data sets were

Purpose: The aim of this study was to report on the development of a standardized target and organ-at-risk naming convention for use in radiation therapy and to present the nomenclature for structure naming for interinstitutional data sharing, clinical trial repositories, integrated multi-institutional collaborative databases, and quality control centers. This taxonomy should also enable improved plan benchmarking between clinical institutions and vendors and facilitation of automated treatment plan quality control. Materials and Methods: The Advanced Technology Consortium, Washington University in St. Louis, Radiation Therapy Oncology Group, Dutch Radiation Oncology Society, and the Clinical Trials RT QA Harmonization Group collaborated in creating this new naming convention. The International Commission on Radiation Units and Measurements guidelines have been used to create standardized nomenclature for target volumes (clinical target volume, internal target volume, planning target volume, etc.), organs at risk, and planning organ-at-risk volumes in radiation therapy. The nomenclature also includes rules for specifying laterality and margins for various structures. The naming rules distinguish tumor and nodal planning target volumes, with correspondence to their respective tumor/nodal clinical target volumes. It also provides rules for basic structure naming, as well as an option for more detailed names. Names of nonstandard structures used mainly for plan optimization or evaluation (rings, islands of dose avoidance, islands where additional dose is needed [dose painting]) are identified separately. Results: In addition to its use in 16 ongoing Radiation Therapy Oncology Group advanced technology clinical trial protocols and several new European Organization for Research and Treatment of Cancer protocols, a pilot version of this naming convention has been evaluated using patient data sets with varying treatment sites. All structures in these data sets were

Reliability of the exercise ECG in detecting silent ischemia in patients with prior myocardial infarction

International Nuclear Information System (INIS)

Yamagishi, Takashi; Matsuda, Yasuo; Satoh, Akira

1991-01-01

To assess the reliability of the exercise ECG in detecting silent ischemia, ECG results were compared with those of stress-redistribution thallium-201 single-photon emission computed tomography (SPECT) in 116 patients with prior myocardial infarction and in 20 normal subjects used as a control. The left ventricle (LV) was divided into 20 segmental images, which were scored blindly on a 5-point scale. The redistribution score was defined as thallium defect score of exercise subtracted by that of redistribution image and was used as a measure of amount of ischemic but viable myocardium. The upper limit of normal redistribution score (=4.32) was defined as mean+2 standard deviations derived from 20 normal subjects. Of 116 patients, 47 had the redistribution score above the normal range. Twenty-five (53%) of the 47 patients showed positive ECG response. Fourteen (20%) of the 69 patients, who had the normal redistribution score, showed positive ECG response. Thus, the ECG response had a sensitivity of 53% and a specificity of 80% in detecting transient ischemia. Furthermore, the 116 patients were subdivided into 4 groups according to the presence or absence of chest pain and ECG change during exercise. Fourteen patients showed both chest pain and ECG change and all these patients had the redistribution score above the normal range. Twenty-five patients showed ECG change without chest pain and 11 (44%) of the 25 patients had the abnormal redistribution. Three (43%) of 7 patients who showed chest pain without ECG change had the abnormal redistribution score. Of 70 patients who had neither chest pain nor ECG change, 19 (27%) had the redistribution score above the normal range. Thus, limitations exist in detecting silent ischemia by ECG in patients with a prior myocardial infarction, because the ECG response to the exercise test may have a low degree of sensitivity and a high degree of false positive and false negative results in detecting silent ischemia.

Posnick, Jeffrey C; Adachie, Anayo; Singh, Neeru; Choi, Elbert

The purposes of this study were to determine the occurrence of undiagnosed "silent" obstructive sleep apnea (OSA) in dentofacial deformity (DFD) patients at initial surgical presentation and to report on the level of daytime sleepiness in DFD patients with OSA and chronic obstructive nasal breathing (CONB) after undergoing bimaxillary, chin, and intranasal surgery. A retrospective cohort study of patients with a bimaxillary DFD and CONB was implemented. Patients were divided into those with no OSA (group I) and those with OSA (group II). Group II was further subdivided into patients referred with polysomnogram (PSG)-confirmed OSA (group IIa) and those with a diagnosis of OSA only after surgical consultation, airway evaluation, and a positive PSG (group IIb). Group II patients were analyzed at a minimum of 1 year after surgery (range, 1 to 10 years) for daytime sleepiness with the Epworth Sleepiness Scale. Patients with postoperative excessive daytime sleepiness were assessed for risk factors and continued need for OSA treatment. Patients in group II were studied to determine which DFD patterns were most associated with OSA. We compared the prevalence of OSA between our study population and the general population. Two hundred sixty-two patients met the inclusion criteria. Of these, 23% (60 of 262) had PSG-confirmed OSA (group II). This rate was much higher than that found in the general population. Of the patients, 7% (19 of 262) were known to have OSA at initial surgical consultation (group IIa). An additional 16% (41 of 262) were later confirmed by PSG to have OSA (group IIb). Patients with primary mandibular deficiency and short face DFDs were most likely to have OSA (P surgery. A significant association was found between group II patients with postoperative excessive daytime sleepiness ("sleepy" or "very sleepy") and a preoperative body mass index category of overweight (P = .026). Our study found silent OSA to be frequent in the DFD population. The

Silent reading of direct versus indirect speech activates voice-selective areas in the auditory cortex.

In human communication, direct speech (e.g., Mary said: "I'm hungry") is perceived to be more vivid than indirect speech (e.g., Mary said [that] she was hungry). However, for silent reading, the representational consequences of this distinction are still unclear. Although many of us share the intuition of an "inner voice," particularly during silent reading of direct speech statements in text, there has been little direct empirical confirmation of this experience so far. Combining fMRI with eye tracking in human volunteers, we show that silent reading of direct versus indirect speech engenders differential brain activation in voice-selective areas of the auditory cortex. This suggests that readers are indeed more likely to engage in perceptual simulations (or spontaneous imagery) of the reported speaker's voice when reading direct speech as opposed to meaning-equivalent indirect speech statements as part of a more vivid representation of the former. Our results may be interpreted in line with embodied cognition and form a starting point for more sophisticated interdisciplinary research on the nature of auditory mental simulation during reading.

Typical subacute thyroiditis was diagnosed in a woman. Three weeks later, signs and symptoms of hyperthyroidism developed in her husband. Although the right lobe of his thyroid gland was slightly enlarged, pain and tenderness were absent throughout the course of his illness. The free thyroxine equivalent (FTE) value and the sedimentation rate were elevated; the low uptake of radioactive iodine by the thyroid gland was consistent with ''silent'' subacute thyroiditis. We postulate that a common etiology, probably viral, was operative in both cases. Nine additional cases of hyperthyroidism with low levels of thyroidal uptake of radioactive iodine are described. The thyroid glands of these patients were normal or slightly enlarged. Antithyroglobulin antibody levels determined in seven patients were not substantially elevated. The clinical course of these patients was characteristic of ''silent'' subacute thyroiditis. Although the origin of the syndrome remains unclear, the disease is self-limited and therapy, if any, is supportive

Developing networks in the immature nervous system and in cellular cultures are characterized by waves of synchronous activity in restricted clusters of cells. Synchronized activity in immature networks is proposed to regulate many different developmental processes, from neuron growth and cell migration, to the refinement of synapses, topographic maps, and the mature composition of ion channels. These emergent activity patterns are not present in all cells simultaneously within the network and more immature "silent" cells, potentially correlated with the presence of silent synapses, are prominent in different networks during early developmental periods. Many current network analyses for detection of synchronous cellular activity utilize activity-based pixel correlations to identify cellular-based regions of interest (ROIs) and coincident cell activity. However, using activity-based correlations, these methods first underestimate or ignore the inactive silent cells within the developing network and second, are difficult to apply within cell-dense regions commonly found in developing brain networks. In addition, previous methods may ignore ROIs within a network that shows transient activity patterns comprising both inactive and active periods. We developed analysis software to semi-automatically detect cells within developing neuronal networks that were imaged using calcium-sensitive reporter dyes. Using an iterative threshold, modulation of activity was tracked within individual cells across the network. The distribution pattern of both inactive and active, including synchronous cells, could be determined based on distance measures to neighboring cells and according to different anatomical layers. © 2015 Wiley Periodicals, Inc.

“The One Who Chases You Away Does Not Tell You Go”: Silent Refusals and Complex Power Relations in Research Consent Processes in Coastal Kenya

Kamuya, Dorcas M.; Theobald, Sally J.; Marsh, Vicki; Parker, Michael; Geissler, Wenzel P.; Molyneux, Sassy C.

Consent processes have attracted significant research attention over the last decade, including in the global south. Although relevant studies suggest consent is a complex negotiated process involving multiple actors, most guidelines assume consent is a one-off encounter with a clear ‘yes’ or ‘no’ decision. In this paper we explore the concept of ‘silent refusals’, a situation where it is not clear whether potential participants want to join studies or those in studies want to withdraw from research, as they were not actively saying no. We draw on participant observation, in-depth interviews and group discussions conducted with a range of stakeholders in two large community based studies conducted by the KEMRI Wellcome Trust programme in coastal Kenya. We identified three broad inter-related rationales for silent refusals: 1) a strategy to avoid conflicts and safeguard relations within households, - for young women in particular—to appear to conform to the wishes of elders; 2) an approach to maintain friendly, appreciative and reciprocal relationships with fieldworkers, and the broader research programme; and 3) an effort to retain study benefits, either for individuals, whole households or wider communities. That refusals and underlying rationales were silent posed multiple dilemmas for fieldworkers, who are increasingly recognised to play a key interface role between researchers and communities in many settings. Silent refusals reflect and reinforce complex power relations embedded in decisions about research participation, with important implications for consent processes and broader research ethics practice. Fieldworkers need support to reflect upon and respond to the ethically charged environment they work in. PMID:25978465

Silent Patent Ductus Arteriosus Aneurysm

Directory of Open Access Journals (Sweden)

Aline Medeiros Botta

2002-09-01

Full Text Available Ductus arteriosus aneurysm, a rare and potentially fatal condition, has been reported as a complication after surgical ductus arteriosus closure. Its spontaneous appearance as a septic complication, which was common in the presurgical and preantibiotic era, has been rarely reported in the contemporary literature. Persistence of silent ductus arteriosus in healthy children and adults is a frequent condition that currently has an increasing diagnostic possibility due to the availability of more accurate investigative methods, especially echocardiography. We report the case of a 1-year-old child, in whom no previous heart disease was known, who developed a giant aneurysm of the ductus arteriosus during a staphylococcal infection. This complication appeared after craniotomy for emptying an accidental subdural hematoma. This report associates the persistence of ductus arteriosus with a complication considered rare, which has a rapidly fatal evolution.

Dynamic wind turbine models in power system simulation tool DIgSILENT

Hansen, A.C.; Jauch, C.; Soerensen, P.; Iov, F.; Blaabjerg, F.

2003-12-01

The present report describes the dynamic wind turbine models implemented in the power system simulation tool DIgSILENT (Version 12.0). The developed models are a part of the results of a national research project, whose overall objective is to create a model database in different simulation tools. This model database should be able to support the analysis of the interaction between the mechanical structure of the wind turbine and the electrical grid during different operational modes. The report provides a description of the wind turbines modelling, both at a component level and at a system level. The report contains both the description of DIgSILENT built-in models for the electrical components of a grid connected wind turbine (e.g. induction generators, power converters, transformers) and the models developed by the user, in the dynamic simulation language DSL of DIgSILENT, for the non-electrical components of the wind turbine (wind model, aerodynamic model, mechanical model). The initialisation issues on the wind turbine models into the power system simulation are also presented. However, the main attention in this report is drawn to the modelling at the system level of two wind turbine concepts: 1. Active stall wind turbine with induction generator 2. Variable speed, variable pitch wind turbine with doubly fed induction generator. These wind turbine concept models can be used and even extended for the study of different aspects, e.g. the assessment of power quality, control strategies, connection of the wind turbine at different types of grid and storage systems. For both these two concepts, control strategies are developed and implemented, their performance assessed and discussed by means of simulations. (au)

Towards Contactless Silent Speech Recognition Based on Detection of Active and Visible Articulators Using IR-UWB Radar.

Science.gov (United States)

Shin, Young Hoon; Seo, Jiwon

2016-10-29

People with hearing or speaking disabilities are deprived of the benefits of conventional speech recognition technology because it is based on acoustic signals. Recent research has focused on silent speech recognition systems that are based on the motions of a speaker's vocal tract and articulators. Because most silent speech recognition systems use contact sensors that are very inconvenient to users or optical systems that are susceptible to environmental interference, a contactless and robust solution is hence required. Toward this objective, this paper presents a series of signal processing algorithms for a contactless silent speech recognition system using an impulse radio ultra-wide band (IR-UWB) radar. The IR-UWB radar is used to remotely and wirelessly detect motions of the lips and jaw. In order to extract the necessary features of lip and jaw motions from the received radar signals, we propose a feature extraction algorithm. The proposed algorithm noticeably improved speech recognition performance compared to the existing algorithm during our word recognition test with five speakers. We also propose a speech activity detection algorithm to automatically select speech segments from continuous input signals. Thus, speech recognition processing is performed only when speech segments are detected. Our testbed consists of commercial off-the-shelf radar products, and the proposed algorithms are readily applicable without designing specialized radar hardware for silent speech processing.

Silent and a audible stereotypes: The constitution of "ethnic character" in Serbian epic poetry

Directory of Open Access Journals (Sweden)

Đerić Gordana

2005-01-01

Full Text Available The article deals with the explanatory relevance of the concept of stereotype in one of its original meanings - as a "mental image". This meaning of the term is the starting point for further differentiations, such as: between linguistic and behavioral stereotypes (in the sense of nonverbal, expected responses; universal and particular stereotypes; self representative and introspective stereotypes; permanent and contemporary stereotypes; and finally, what is most important for our purposes, the difference between silent and audible stereotypes. These distinctions, along with the functions of stereotype, are discussed in the first part of the paper. In the second part, the relations of silent and audible stereotypes are tested against the introduction of "innovative vocabularies" in popular lore. In other words, the explanatory power of this differentiation is checked through an analysis of unconventional motives in Serbian epic poems. The goal of the argument is to clarify the procedure of self creation of masculinity as a relevant feature of the "national character" through "tactic games" of silent and audible stereotypes. The examination of these "poetic strategies" serves a twofold purpose: to illustrate the process of constructing particular features of the "ethno type", on one hand, and to check hypotheses and models which are taken as frameworks in analyzing stereotypes, on the other.

When Spiders Bite: The Use, Misuse, and Unintended Consequences of ``Silent Information''

Science.gov (United States)

Keenan, Thomas P.

Spiders are the workhorses of the Internet, silently (and almost invisibly) traversing the online world, 24 hours a day, looking for information that may be of interest to someone. It is being archived, organized, and sold, usually without the knowledge or consent of the subject of the information. Serious consequences are starting to appear, such as the withdrawal of three candidates from the October 2008 Canadian Federal election because of previous online indiscretions. While these were intentional if mis-guided postings, information made available without our consent can have equally devastating effects. Advances in artificial intelligence, as well as the increasing tendency to post more and more information, such as videos, will make the gathering, aggregation, and republishing of this “silent information” an increasingly important issue that must be addressed from the technical, social, ethical and legal perspectives, and sooner rather than later.

201Tl myocardial SPECT and β-endorphin levels in patients with suspected silent ischemia

Lind, P.; Binter, G.; Koeltringer, P.; Eber, O.; Eber, B.; Klein, W.; Brandt, D.

1990-01-01

Today silent myocardial ischemia (SMI) is a well-recognized phenomenon. Treadmill exercise according to the Bruce protocol, 201 Tl myocardial SPECT and coronary angiography were performed in a total of 106 patients with suspected SMI. In group I (high probability of ischemia; n=46), reversible defects detected by SPECT correlated well with significant stenoses and irreversible defects with subtotal stenoses or complete occlusions. SPECT sensitivity in the detection of ischemia was 91%, its specificity 96%. In group II (low probability of ischemia; n=60), SPECT sensitivity was as high as in group I (94%) but due to a high number of false-positive results (e.g. cardiomyopathy) specificity was only 75%. However, SPECT was superior to exercise ECG (sensitivity 70%; specificity 56%) in the detection of SMI. In addition, β-endorphin levels were determined in 180 healthy subjects, 37 patients with symptomatic CAD and in 34 patients with SMI before and during maximum exercise. Exercise values in patients with SMI were significantly higher than in healthy subjects or in patients with symptomatic CAD. (orig./MG) [de

The aim of this study was to evaluate the prevalence of silent myocardial ischemia in a group of patients with asymptomatic carotid stenosis.Methods: A total of 37 patients with asymptomatic carotid plaques, without chest pain or dyspnea, was investigated. These patients were studied for age, sex, hypertension, diabetes, dyslipidemia, smoking, and family history of cardiac disease, and underwent technetium-99 m sestamibi myocardial stress-rest scintigraphy and echo-color Doppler examination of carotid arteries.Results: A statistically significant relationship (P = 0.023 was shown between positive responders and negative responders to scintigraphy test when both were tested for degree of stenosis. This relationship is surprising in view of the small number of patients in our sample. Individuals who had a positive scintigraphy test had a mean stenosis degree of 35% ± 7% compared with a mean of 44% ± 13% for those with a negative test. Specificity of our detection was 81%, with positive and negative predictive values of 60% and 63%, respectively.Conclusion: The present study confirms that carotid atherosclerosis is associated with coronary atherosclerosis and highlights the importance of screening for ischemic heart disease in

A J wave is a common electrocardiographic finding in the general population. Individuals with prominent J waves in multiple electrocardiogram (ECG) leads have a higher risk of lethal arrhythmias than those with low-amplitude J waves. There are few reports about the relationship between thyroid function and J-wave amplitude. We report the case of a 45-year-old man who had unexpected ventricular fibrillation (VF). He had dynamic J-point elevation in multiple ECG leads. Possible early repolarization syndrome was diagnosed. He also had thyrotoxicosis caused by silent thyroiditis, and his J-wave amplitude decreased according to changes in thyroid function because of spontaneous remission of silent thyroiditis. There was a positive correlation between serum triiodothyronine levels and J-wave amplitudes. The findings in case suggested silent thyroiditis may contribute to the occurrence of VF in a patient with dynamic changes in J-point elevation in multiple ECG leads. Thyrotoxicosis is a relatively common endocrine disease; therefore, clinicians should pay attention to J-wave amplitude in the ECG of patients with thyrotoxicosis.

Full Text Available With reference to Finno-Permic languages (a branch of Finno-Ugric languages excluding Ugric languages, the article analyses compound names of plants (phytonyms containing Permic languages, which, inter alia, can be explained by the incompleteness of collected data. Most of phytonyms with anthroponymic elements are attested in the Finnish and Estonian languages, while in the other Finno-Permic languages such attestations are rare. The anthroponyms appearing in names of plants are divided into two groups: a personal names of Biblical origin (e.g. Finnish Aapraham, Aatam, Jeesus, Maaria, b other anthroponyms. In the first group, the most numerous are Balto-Fennic phytonyms with the names Johannes and Maria and their national variants. The name Johannes (Finnish Juhannus, Estonian Jaan is most often present in the names of herbaceous plants flourishing in the period of celebration of Saint John’s Eve. Traditionally, this feast is associated with numerous rites and customs in which some plants play a significant role. An interesting formal feature of Balto-Fennic deanthroponymic compound names of plants is alliteration, i.e. repetition of identical or similar sound clusters in the beginning of each part of the word, as in Finnish liisanlilukka ‘stone bramble,’ simonsien’ ‘chanterelle, girolle’.

Children with sickle cell anemia have a higher-than-expected prevalence of poor educational attainment. We test two key hypotheses about educational attainment among students with sickle cell anemia, as measured by grade retention and use of special education services: (1) lower household per capita income is associated with lower educational attainment; (2) the presence of a silent cerebral infarct is associated with lower educational attainment. We conducted a multicenter, cross-sectional study of cases from 22 U.S. sites included in the Silent Infarct Transfusion Trial. During screening, parents completed a questionnaire that included sociodemographic information and details of their child’s academic status. Of 835 students, 670 were evaluable; 536 had data on all covariates and were used for analysis. The students’ mean age was 9.4 years (range: 5–15) with 52.2% male; 17.5% of students were retained one grade level and 18.3% received special education services. A multiple variable logistic regression model identified that lower household per capita income (odds ratio [OR] of quartile 1 = 6.36, OR of quartile 2 = 4.7, OR of quartile 3 = 3.87; P = 0.001 for linear trend), age (OR = 1.3; P sickle cell anemia, household per capita income is associated with grade retention, whereas the presence of a silent cerebral infarct is not. Future educational interventions will need to address both the medical and socioeconomic issues that affect students with sickle cell anemia. PMID:25042018

Semantic Web Compatible Names and Descriptions for Organisms

Wang, H.; Wilson, N.; McGuinness, D. L.

Modern scientific names are critical for understanding the biological literature and provide a valuable way to understand evolutionary relationships. To validly publish a name, a description is required to separate the described group of organisms from those described by other names at the same level of the taxonomic hierarchy. The frequent revision of descriptions due to new evolutionary evidence has lead to situations where a single given scientific name may over time have multiple descriptions associated with it and a given published description may apply to multiple scientific names. Because of these many-to-many relationships between scientific names and descriptions, the usage of scientific names as a proxy for descriptions is inevitably ambiguous. Another issue lies in the fact that the precise application of scientific names often requires careful microscopic work, or increasingly, genetic sequencing, as scientific names are focused on the evolutionary relatedness between and within named groups such as species, genera, families, etc. This is problematic to many audiences, especially field biologists, who often do not have access to the instruments and tools required to make identifications on a microscopic or genetic basis. To better connect scientific names to descriptions and find a more convenient way to support computer assisted identification, we proposed the Semantic Vernacular System, a novel naming system that creates named, machine-interpretable descriptions for groups of organisms, and is compatible with the Semantic Web. Unlike the evolutionary relationship based scientific naming system, it emphasizes the observable features of organisms. By independently naming the descriptions composed of sets of observational features, as well as maintaining connections to scientific names, it preserves the observational data used to identify organisms. The system is designed to support a peer-review mechanism for creating new names, and uses a controlled

Full Text Available Further cholestrol lowering may affect silent ischemia detected on holter monitoring. Cholesterol lowering is associated with a reduction in cardiovascular morbidity and mortality. Statins are the main drugs for cholesterol lowering. Ezetimibe when added to statins gives further reduction in cholesterol but its long-term effect on cardiovascular morbidity and mortality and ischemic events is not known. This study sought to determine whether further cholesterol lowering with ezitimibe will also results in a reduction of myocardial ischemia during daily life. We enrolled 50 patients with proven stable coronary artery disease (CAD and at least one episode of ST-segment depression on ambulatory ECG monitoring. All of them were receiving optimal therapy for CAD including statin therapy for cholesterol reduction. 25 patients were randomized to continue their statin therapy (Statin only group and 25 to recieve statin plus ezitimibe 10 mg/day (ezitimibe group. Serum cholesterol and LDL cholesterol levels and ambulatory monitoring were repeated after 4–6 months of therapy. The two groups were comparable with respect to baseline characteristics, number of episodes of ST-segment depression, and baseline serum cholesterol levels. The ezitimibe group had lower mean total and LDL cholesterol levels at study end and experienced a significant reduction in the number of episodes of ST-segment depression compared with the statin only group. ST-segment depression was completely resolved in 13 of 25 patients (52% in the ezitimibe group versus 3 of 25 (12% in the statin only group. The ezitimibe group exhibited a highly significant reduction in ambulatory ischemia (P < .001. By logistic regression, treatment with ezitimibe was an independent predictor of ischemia resolution. Further cholesterol lowering with ezitimibe can result in reduction or resolution of myocardial ischemia recorded as episodes of ST-segment depression in ambulatory monitoring of the ECG.

Samargia, Sharyl; Schmidt, Rebekah; Kimberley, Teresa Jacobson

2014-02-07

The purpose of this study was to compare cortical inhibition in the hand region of the primary motor cortex between subjects with focal hand dystonia (FHD), adductor spasmodic dysphonia (AdSD), and healthy controls. Data from 28 subjects were analyzed (FHD n=11, 53.25 ± 8.74 y; AdSD: n=8, 56.38 ± 7.5 y; and healthy controls: n=941.67 ± 10.85 y). All subjects received single pulse TMS to the left motor cortex to measure cortical silent period (CSP) in the right first dorsal interosseus (FDI) muscle. Duration of the CSP was measured and compared across groups. A one-way ANCOVA with age as a covariate revealed a significant group effect (p<0.001). Post hoc analysis revealed significantly longer CSP duration in the healthy group vs. AdSD group (p<0.001) and FHD group (p<0.001). These results suggest impaired intracortical inhibition is a neurophysiologic characteristic of FHD and AdSD. In addition, the shortened CSP in AdSD provides evidence to support a widespread decrease in cortical inhibition in areas of the motor cortex that represent an asymptomatic region of the body. These findings may inform future investigations of differential diagnosis as well as alternative treatments for focal dystonias. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Silent Localization of Underwater Sensors Using Magnetometers

2010-01-01

Full Text Available Sensor localization is a central problem for sensor networks. If the sensor positions are uncertain, the target tracking ability of the sensor network is reduced. Sensor localization in underwater environments is traditionally addressed using acoustic range measurements involving known anchor or surface nodes. We explore the usage of triaxial magnetometers and a friendly vessel with known magnetic dipole to silently localize the sensors. The ferromagnetic field created by the dipole is measured by the magnetometers and is used to localize the sensors. The trajectory of the vessel and the sensor positions are estimated simultaneously using an Extended Kalman Filter (EKF. Simulations show that the sensors can be accurately positioned using magnetometers.

Soundless Speech/ Wordless Writing: Language and German Silent Cinema

Full Text Available Speech / Wordless Writing: Language and German Silent Cinema Marc Silberman If language loses its communicative and interpretative functions in direct proportion to the loss of its referential grounding, then the modernist crisis is simultaneously a crisis of its signifying practices. This means that the evolution of the silent cinema is a particularly rich site to examine the problematic relationship of language and image. This essay presents several expressionist films as a specific response to this crisis in order to describe the diverse cinematic forms of resistance to the word, to articulated speech. While some film makers developed the silence of the silent film into a “gestural language” that dramatized light and movement, others reproduced the film figures’ silent speech by means of graphically stylized intertitles. My thesis is that the expressionist cinema maintained an idealistic notion of the film as a pure work of art that aimed at a unified composition of all elements and missed the opportunity to explore the rich semiotic possibilities of the new technological medium with its hybrid, synergetic forms and provocative force. Hence, the expressionist cinema marks a transition or even the endpoint of a long process of reflection about the communicative possibilities of language that shifted to a fundamentally new level with the invention of sound cinema at the end of the 1920s. Parole muette / écriture sans mot: Le langage et le cinéma allemand muet Marc Silberman Le langage, dit-on, perd de ses functions communicatrices et interpretatives en proportion directe à la perte de sa force référentielle. On dira que la crise moderniste est également une crise des pratiques signifiantes. Ce qui revient à dire aussi que l’évolution du cinéma muet serait une site particulièrement riche pour examiner les problématiques du langage vs. l’image.

The Buddhist Tzu Chi Silent Mentor Program promotes the donation of one's body to science as a selfless act by appealing to the Buddhist ethics of compassion and self-sacrifice. Together, faculty, families, and donors help medical students to learn the technical, spiritual, emotional, and psychological aspects of medicine. Students assigned to each "Silent Mentor" visit the family to learn about the donor's life. They see photos and hear family members' stories. Afterwards, students write a brief biography of the donor which is posted on the program website, in the medical school, and on the dissection table. In this paper, we: (1) summarize the Silent Mentor Program; (2) describe findings from an assessment of medical students who recently completed a new version of the program in Malaysia; and (3) explore how healthcare settings could benefit from this innovative program.

Magnetic resonance (MR) imaging was performed in 12 patients who incurred manic state after the age of 50 (manic group). Twelve other age- and sex-matched patients who incurred emotional disturbance at the young age served as controls. Patients with a history of cerebral stroke and local neurologic symptoms were excluded. Silent cerebral infarction (SCI) were concomitantly seen on MR images in 66.7% in the manic group, which was significantly higher than the control group (16.7%). Approximately half of the patients in the manic group seemed to be in the parenchymal manic state associated with SCI. Patients in the manic state associated with SCI was at a risk for developing cerebral stroke. Therefore, the treatment such as antithrombin therapy for cerebrovascular disorder was considered important, from the viewpoint of early treatment of cerebral infarction. Since lesions were frequently observed in the right frontal lobe and basal nucleus in manic patients with the associated SCI, these sites may be in part involved in the occurrence of manic state.

In daily life, responses are often facilitated by anticipatory imagery of expected targets which are announced by associated stimuli from different sensory modalities. Silent music reading represents an intriguing case of visuotonal modality transfer in working memory as it induces highly defined auditory imagery on the basis of presented visuospatial information (i.e. musical notes). Using functional MRI and a delayed sequence matching-to-sample paradigm, we compared brain activations during retention intervals (10s) of visual (VV) or tonal (TT) unimodal maintenance versus visuospatial-to-tonal modality transfer (VT) tasks. Visual or tonal sequences were comprised of six elements, white squares or tones, which were low, middle, or high regarding vertical screen position or pitch, respectively (presentation duration: 1.5s). For the cross-modal condition (VT, session 3), the visuospatial elements from condition VV (session 1) were re-defined as low, middle or high "notes" indicating low, middle or high tones from condition TT (session 2), respectively, and subjects had to match tonal sequences (probe) to previously presented note sequences. Tasks alternately had low or high cognitive load. To evaluate possible effects of music reading expertise, 15 singers and 15 non-musicians were included. Scanner task performance was excellent in both groups. Despite identity of applied visuospatial stimuli, visuotonal modality transfer versus visual maintenance (VT>VV) induced "inhibition" of visual brain areas and activation of primary and higher auditory brain areas which exceeded auditory activation elicited by tonal stimulation (VT>TT). This transfer-related visual-to-auditory activation shift occurred in both groups but was more pronounced in experts. Frontoparietal areas were activated by higher cognitive load but not by modality transfer. The auditory brain showed a potential to anticipate expected auditory target stimuli on the basis of non-auditory information and

Learning face-name pairings at a social function becomes increasingly more difficult the more individuals one meets. This phenomenon is attributable to proactive interference--the negative influence of prior learning on subsequent learning. Recent evidence suggests that taking a memory test can alleviate proactive interference in verbal list learning paradigms. We apply this technique to face-name pair learning. Participants studied four lists of 12 face-name pairings and either attempted to name the 12 faces just studied after every list or did not. Recall attempts after every list improved learning of the fourth list by over 100%. Moreover, no reduction in learning of face-name pairings occurred from list 1 to list 4 for participants who attempted to name studied faces between lists. These results suggest that testing oneself on the names of a group of new acquaintances before moving on to the next group is an effective mnemonic technique for social functions.

An investigation of the reduction of carbon dioxide in a silent electric discharge

1978-01-01

The reduction of CO2 to O2 and CO in a silent electric discharge was studied. It was found that current alone (in the ionized plasma induced by the silent electric discharge) was reponsible for the CO2 reduction process. Voltage and frequency were important only in so far as they induced current in the plasma. Pressure and temperature were of minimum influence in the process. The large power consumption in the process was recognized as resulting from the low power factor of the reactor vessel which electrically behaved like a capacitor. The power factor was subsequently improved by adding an inductive element to make the reactor vessel capacitance part of a resonant circuit. It was found that the CO2 reduction process was most efficient in terms of power vs reduction rate when a voltage was employed that was only slightly higher than that needed to induce the plasma.

More people are supplementing conventional medicine with complementary and alternative medicine (CAM), but studies have not compared CAM use between baby boomers (adults born from 1946 to 1964) and the so-called silent generation (born from 1925 to 1945). This study compares CAM usage between baby boomers (n = 7734) and the silent generation (n = 4682) through secondary analyses of the 2007 National Health Interview Survey data. The analysis also compares chronic disease and pain status. Multivariate logistic regression models were developed to identify generational differences. Although the silent generation reported twice as many chronic disease (51.3% vs 26.1%; P painful conditions (56.1% vs 52.2%; P CAM within the past year (43.1% vs 35.4%; P CAM than adults from the silent generation. Chronic pain status was independently associated with greater CAM use (adjusted odds ratio, 2.26; 95% confidence interval, 2.03-2.52). Baby boomers reported significantly higher rates of CAM use than the silent generation for both chronic diseases and painful conditions. Family physicians caring for the aging population must use patient-centered communication about the risks/benefits of CAM, which is necessary to promote effective coping with chronic illnesses and pain. © Copyright 2014 by the American Board of Family Medicine.

Three New and Eleven Known Unusual C25 Steroids: Activated Production of Silent Metabolites in a Marine-Derived Fungus by Chemical Mutagenesis Strategy using Diethyl Sulphate

Ming-Wen Xia

2014-03-01

Full Text Available Three new (1–3 and 11 known (4–14 C25 steroids with an unusual bicyclo[4.4.1]A/B ring system were isolated by tracing newly produced metabolites in the EtOAc extract of an antitumor mutant AD-1-2 obtained by the diethyl sulphate (DES mutagenesis of a marine-derived Penicillium purpurogenum G59. HPLC-PDAD-UV and HPLC-ESI-MS analyses indicated that the G59 strain did not produce these metabolites and the production of 1–14 in the mutant AD-1-2 extract was caused by the activation of silent metabolites in the original G59 strain by DES mutagenesis. The structures of the new compounds, named antineocyclocitrinols A (1 and B (2 and 23-O-methylantineocyclocitrinol (3, including their absolute configurations were determined by various spectroscopic methods, especially the NMR and Mo2-induced CD analyses. Compounds 1–3 provide the first examples of the C25 bicyclo[4.4.1]A/B ring steroids with the Z-configuration of 20,22-double bond. All of 1–14 weakly inhibited several human cancer cell lines to varying extents. These results provided additional examples for the successful application of the chemical mutagenesis strategy using DES to discover new compounds by activating silent metabolites in fungal isolates and supported also the effectiveness and usefulness of this new strategy.

Edmonds, Lisa A; Donovan, Neila J

2014-06-01

Virtually no valid materials are available to evaluate confrontation naming in Spanish-English bilingual adults in the U.S. In a recent study, a large group of young Spanish-English bilingual adults were evaluated on An Object and Action Naming Battery (Edmonds & Donovan in Journal of Speech, Language, and Hearing Research 55:359-381, 2012). Rasch analyses of the responses resulted in evidence for the content and construct validity of the retained items. However, the scope of that study did not allow for extensive examination of individual item characteristics, group analyses of participants, or the provision of testing and scoring materials or raw data, thereby limiting the ability of researchers to administer the test to Spanish-English bilinguals and to score the items with confidence. In this study, we present the in-depth information described above on the basis of further analyses, including (1) online searchable spreadsheets with extensive empirical (e.g., accuracy and name agreeability) and psycholinguistic item statistics; (2) answer sheets and instructions for scoring and interpreting the responses to the Rasch items; (3) tables of alternative correct responses for English and Spanish; (4) ability strata determined for all naming conditions (English and Spanish nouns and verbs); and (5) comparisons of accuracy across proficiency groups (i.e., Spanish dominant, English dominant, and balanced). These data indicate that the Rasch items from An Object and Action Naming Battery are valid and sensitive for the evaluation of naming in young Spanish-English bilingual adults. Additional information based on participant responses for all of the items on the battery can provide researchers with valuable information to aid in stimulus development and response interpretation for experimental studies in this population.

2012-01-01

Neonatal seizures can lead to epilepsy and long-term cognitive deficits in adulthood. Using a rodent model of the most common form of human neonatal seizures, hypoxia-induced seizures (HS), we aimed to determine whether these seizures modify long-term potentiation (LTP) and “silent” N-methyl-D-aspartate receptor (NMDAR)-only synapses in hippocampal CA1. At 48-72 hours (hrs) post-HS, electrophysiology and immunofluorescent confocal microscopy revealed a significant decrease in the incidence of silent synapses, and an increase in amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) at the synapses. Coincident with this decrease in silent synapses, there was an attenuation of LTP elicited by either tetanic stimulation of Schaffer collaterals or a pairing protocol, and persistent attenuation of LTP in slices removed in later adulthood after P10 HS. Furthermore, post-seizure treatment in vivo with the AMPAR antagonist 2,3-dihydroxy-6-nitro-7-sulfonyl-benzo[f]quinoxaline (NBQX) protected against the HS-induced depletion of silent synapses and preserved LTP. Thus, this study demonstrates a novel mechanism by which early-life seizures could impair synaptic plasticity, suggesting a potential target for therapeutic strategies to prevent long-term cognitive deficits.

The role of NASA's Earth Science Data Systems Working Groups (ESDSWG) is to make recommendations relevant to NASA's Earth science data systems from users' experiences and community insight. Each group works independently, focusing on a unique topic. Progress of two of the 2017 Working Groups will be presented. In a single airborne field campaign, there can be several different instruments and techniques that measure the same parameter on one or more aircraft platforms. Many of these same parameters are measured during different airborne campaigns using similar or different instruments and techniques. The Airborne Composition Standard Variable Name Working Group is working to create a list of variable standard names that can be used across all airborne field campaigns in order to assist in the transition to the ICARTT Version 2.0 file format. The overall goal is to enhance the usability of ICARTT files and the search ability of airborne field campaign data. The Time Series Working Group (TSWG) is a continuation of the 2015 and 2016 Time Series Working Groups. In 2015, we started TSWG with the intention of exploring the new OGC (Open Geospatial Consortium) WaterML 2 standards as a means for encoding point-based time series data from NASA satellites. In this working group, we realized that WaterML 2 might not be the best solution for this type of data, for a number of reasons. Our discussion with experts from other agencies, who have worked on similar issues, identified several challenges that we would need to address. As a result, we made the recommendation to study the new TimeseriesML 1.0 standard of OGC as a potential NASA time series standard. The 2016 TSWG examined closely the TimeseriesML 1.0 and, in coordination with the OGC TimeseriesML Standards Working Group, identified certain gaps in TimeseriesML 1.0 that would need to be addressed for the standard to be applicable to NASA time series data. An engineering report was drafted based on the OGC Engineering

Compound Slavic names refer in their structure to names from other groups of the Indo-European community and are closely linked with a nation’s spiritual culture and appropriate ultimate and instrumental values. In Indo-European languages a different number of lexical components is used in names as their first or second part: in Old Indian - 865; in Old Persian and Median - 43; in Greek - 1015; in the Celtic group - 336; the German one - 1800 and in the Slavic group - 220. The most numerous in Old Polish anthroponomastics were names with the component slaw. As the first component - slaw appears in 4 names, and as the second, in 100. This component has appeared from times immemorial in Indian, Avestan, Greek and Illyrian names. Name Stanislaus is known in all Slavic countries, while its feminine form only in Polish, Bulgarian, Serb and Croatian. In Poland it has been in use since very old times up to now. Numerous surnames and names of places derive from it. The popularity of the name

Medieval Karelian Calendar Names: A Cognitive Perspective

Directory of Open Access Journals (Sweden)

Irina A. Kyurshunova

2013-11-01

Full Text Available The article focuses on calendar personal names recorded in the 15–17th centuries Russian and Swedish manuscripts written in Karelia. Revealing the cognitive potential of this historical stratum of names, the author analyzes the frequency of full (official and modified forms of calendar names, the regional peculiarities of their linguistic adaptation, their ethnolinguisitic and social status, as well as the functioning of calendar names in the regional onomastic system. The analysis shows that the calendar onomasticon holds the leading positions, which reflects important axiological and mental shifts in the people’s culture. The list of most frequent Christian names of the region generally coincides with the onomastic data related to other Russian territories of the same period. The conservation of the name nomenclature is due to family traditions, namely, to familial practices of naming. However, the adaptation and distribution of names display some regional features, particularly in the frequency of different groups of anthroponyms. The peripheral situation of the region and the presence of Balto-Fennic population which adapted the Russian calendar athroponymicon determined the “conservatism” of the calendar names nomenclature: for naming, they selected the names which were better adapted and more extensively used among Russians. The formation of modified names depended mostly on the morphemic structure of the Russian language, regional features being relatively insignificant. The frequency of modified forms of names correlates with the genre of the manuscript and the scribe’s arbitrariness.

Proposal for the systematic naming of mesons and baryons

International Nuclear Information System (INIS)

Porter, F.C.; Hernandez, J.J.; Montanet, L.

1984-10-01

Twenty years ago, the Particle Data Group adopted a systematic naming convention for baryons: the symbols N, Δ, Λ, Σ, Ψ, and Ω were to identify the isospin and strangeness, The mesons, by contrast, have become an alphabet soup of uninformative names - theta, iota, xi, zeta, g/sub T/, g/sub s/, H, E, delta, h, g, r, kappa, etc. -, and in some cases identical names are used for mesons with different quantum numbers (A, B, and D). Furthermore, experimentalists are now discovering baryons that contain heavy quarks. It is therefore timely to consider systematic naming conventions both for mesons and for baryons with heavy quarks. The Particle Data Group is circulating this proposal in the hope of generating feedback, and we attach a sheet for responses. It should be emphasized that the Particle Tables would show both the old and new names for some time

The objective of the present study was to investigate whether moderately experienced meditators activate hippocampus and the prefrontal cortex during silent mantra meditation, as has been observed in earlier studies on subjects with several years of practice. Subjects with less than 2 years of meditation practice according to the Kundalini yoga or Acem tradition were examined by functional magnetic resonance imaging during silent mantra meditation, using an on-off block design. Whole-brain as well as region-of-interest analyses were performed. The most significant activation was found in the bilateral hippocampus/parahippocampal formations. Other areas with significant activation were the bilateral middle cingulate cortex and the bilateral precentral cortex. No activation in the anterior cingulate cortex was found, and only small activation clusters were observed in the prefrontal cortex. In conclusion, the main finding in this study was the significant activation in the hippocampi, which also has been correlated with meditation in several previous studies on very experienced meditators. We propose that the hippocampus is activated already after moderate meditation practice and also during different modes of meditation, including relaxation. The role of hippocampal activity during meditation should be further clarified in future studies, especially by investigating whether the meditation-correlated hippocampal activity is related to memory consolidation.

Silent communication: toward using brain signals.

Science.gov (United States)

Pei, Xiaomei; Hill, Jeremy; Schalk, Gerwin

2012-01-01

From the 1980s movie Firefox to the more recent Avatar, popular science fiction has speculated about the possibility of a persons thoughts being read directly from his or her brain. Such braincomputer interfaces (BCIs) might allow people who are paralyzed to communicate with and control their environment, and there might also be applications in military situations wherever silent user-to-user communication is desirable. Previous studies have shown that BCI systems can use brain signals related to movements and movement imagery or attention-based character selection. Although these systems have successfully demonstrated the possibility to control devices using brain function, directly inferring which word a person intends to communicate has been elusive. A BCI using imagined speech might provide such a practical, intuitive device. Toward this goal, our studies to date addressed two scientific questions: (1) Can brain signals accurately characterize different aspects of speech? (2) Is it possible to predict spoken or imagined words or their components using brain signals?

Silent synapses in neuromuscular junction development.

Tomàs, Josep; Santafé, Manel M; Lanuza, Maria A; García, Neus; Besalduch, Nuria; Tomàs, Marta

2011-01-01

In the last few years, evidence has been found to suggest that some synaptic contacts become silent but can be functionally recruited before they completely retract during postnatal synapse elimination in muscle. The physiological mechanism of developmental synapse elimination may be better understood by studying this synapse recruitment. This Mini-Review collects previously published data and new results to propose a molecular mechanism for axonal disconnection. The mechanism is based on protein kinase C (PKC)-dependent inhibition of acetylcholine (ACh) release. PKC activity may be stimulated by a methoctramine-sensitive M2-type muscarinic receptor and by calcium inflow though P/Q- and L-type voltage-dependent calcium channels. In addition, tropomyosin-related tyrosine kinase B (trkB) receptor-mediated brain-derived neurotrophic factor (BDNF) activity may oppose the PKC-mediated ACh release depression. Thus, a balance between trkB and muscarinic pathways may contribute to the final functional suppression of some neuromuscular synapses during development. © 2010 Wiley-Liss, Inc.

Diminished responding to hearing one's own name is one of the earliest and strongest predictors of autism spectrum disorder (ASD). Here, we studied, for the first time, the neural correlates of hearing one's own name in ASD. Based on existing research, we hypothesized enhancement of late parietal positive activity specifically for the own name in neurotypicals, and for this effect to be reduced in adults with ASD. Source localization analyses were conducted to estimate group differences in brain regions underlying this effect. Twenty-one adults with ASD, and 21 age- and gender-matched neurotypicals were presented with 3 categories of names (own name, close other, unknown other) as task-irrelevant deviant stimuli in an auditory oddball paradigm while electroencephalogram was recorded. As expected, late parietal positivity was observed specifically for own names in neurotypicals, indicating enhanced attention to the own name. This preferential effect was absent in the ASD group. This group difference was associated with diminished activation in the right temporoparietal junction (rTPJ) in adults with ASD. Further, a familiarity effect was found for N1 amplitude, with larger amplitudes for familiar names (own name and close other). However, groups did not differ for this effect. These findings provide evidence of atypical neural responding to hearing one's own name in adults with ASD, suggesting a deficit in self-other distinction associated with rTPJ dysfunction.

We have detected six narrow-line Seyfert 1 (NLS1) galaxies at 37 GHz that were previously classified as radio silent and two that were classified as radio quiet. These detections reveal the presumption that NLS1 galaxies labelled radio quiet or radio silent and hosted by spiral galaxies are unable to launch jets to be incorrect. The detections are a plausible indicator of the presence of a powerful, most likely relativistic jet because this intensity of emission at 37 GHz cannot be explained by, for example, radiation from supernova remnants. Additionally, one of the detected NLS1 galaxies is a newly discovered source of gamma rays and three others are candidates for future detections. 37 GHz data are only available in electronic form at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/614/L1

We studied the influences of silent brain infarction (SBI) and hypertension on brain atrophy and its longitudinal progression in healthy adults. MRI scans were performed on 109 neurologically normal adults (mean age, 58.6±5.8 years), with follow-up at an average of 4.9 years later. Patient histories of hypertension, smoking habits, and alcohol consumption were examined. We evaluated brain atrophy using the brain atrophy index (BAI; the ratio of the brain area to the intracranial area) and the ventricular atrophy index (VAI; the ratio of the ventricular area to the brain area) on MRI T1-weighted images at the levels of the basal ganglia and lateral ventricle in horizontal sections. There were no differences in age, sex, dyslipidemia, body mass index (BMI), smoking habit, and alcohol consumption between the normal group and the SBI or hypertension group. The BAI was significantly lower at entry for the SBI (+) group than for the SBI (-) group at both the basal ganglia and lateral ventricle levels (basal ganglia level, p=0.02; and lateral ventricle level, p=0.05). Moreover, the VAI was significantly higher at entry for the SBI (+) group than for the SBI (-) group at the lateral ventricle level (p=0.03). Furthermore, the BAI was significantly lower at entry for the hypertensive group than for the non-hypertensive group at the basal ganglia level (p=0.007). There were no significant differences in the annual variations of the BAI and VAI between the normal group and the SBI (+) or hypertensive group. The present results suggest that the SBI and hypertension are accelerating factors for brain atrophy and ventricular dilatation. (author)

Sixty consecutive patients were studied who had positive responses to Naughton exercise treadmill testing (at least 1.5 mm of ST-segment shift in at least 2 leads or thallium reperfusion abnormalities) with or without symptoms of angina 11 +/- 1 days after acute myocardial infarction (AMI). All patients had undergone coronary angiography 24 +/- 4 days after infarction. Thirty-eight patients (63%) had no treadmill angina (silent ischemia, group I) and 22 patients had typical treadmill angina (symptomatic ischemia, group II). Use of beta-blocking drugs, calcium antagonists and nitrates at the time of exercise testing did not differ in the 2 groups. All 9 patients with diabetes mellitus were in the asymptomatic group (p less than 0.40) and group I had a greater proportion of inferior wall AMI (30 of 38) than group II (11 of 22, p = 0.02). Total exercise treadmill test duration (group I 422 +/- 31 seconds, group II 400 +/- 46 seconds) and rate-pressure product were not different in the 2 groups. The number of patients unable to exercise 5 minutes (12 in group I and 7 in group II), the number with diffuse electrocardiographic changes (9 in group I and 7 in group II), and the number with inadequate blood pressure response (8 in group I and 4 in group II) were also similar. At coronary arteriography the mean number of arteries with at least 70% diameter stenosis was 2.0 +/- 0.2 in group I and 2.2 +/- 0.2 in group II (difference not significant)

Coronary angiography (CAG) is an invasive diagnostic procedure, which could lead to procedure related complications. One of the well known post-procedural complications is cerebral embolic infarction with or without symptoms. Silent embolic cerebral infarction (SECI) has clinical significance because it can progress to a decline in cognitive function and increase the risk of dementia in the long term. The aim of this study was to detect the incidence and predictors of SECI after diagnostic CAG using diffusion-weighted magnetic resonance imaging (DW-MRI). A total of 197 patients with coronary artery disease who underwent DW-MRI for evaluation of intracranial vasculopathy before coronary artery bypass graft surgery were retrospectively enrolled in the present study. DW-MRI was performed within 48 h after diagnostic CAG. SECI was diagnosed as presence of focal bright high signal intensity in DW-MRI. Patients were divided into groups according to presence/absence of SECI (+ SECI vs. - SECI, respectively). The clinical and angiographic characteristics were analyzed and independent predictors were evaluated. Of the 197 patients, SECI occurred in 20 patients (10.2%) after diagnostic CAG. Age, female gender, frequency of underlying atrial fibrillation, extent of coronary disease, and fluoroscopic time during diagnostic CAG were not different between the + SECI and - SECI groups. Left ventricular ejection fraction was significantly lower in the + SECI group than in the - SECI group (45.9 ± 8.5% vs. 51.4 ± 13.1%, p=0.014) and performance rate of internal mammary artery (IMA) angiography was significantly higher in the + SECI group compared with the - SECI group (85% vs. 37.2%, pSECI (OR=14.642; 95% CI=3.201 to 66.980, p=0.001). The incidence of SECI after diagnostic CAG was not infrequent. Diagnostic CAG with IMA angiography may increase the risk of SECI. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

To implement and evaluate a multiple-process functional magnetic resonance imaging (fMRI) paradigm designed to effectively and efficiently activate several language-related regions for use with neurosurgical patients. Both overt and covert response conditions were examined. The fMRI experiments compared the traditional silent word-generation condition versus an overt one as they engage frontal language regions (Experiment 1) and silent versus overt semantic association conditions as they engage multiple language processing regions (Experiment 2). In Experiment 1 the overt condition yielded greater magnitude of activation, but not volume of activation, in the left inferior frontal and insular cortices than did the silent condition for most, but not all, participants. Experiment 2 demonstrated that the activation of multiple established language processing regions (ie, orthographic, phonological and semantic) can be achieved in a significant number of participants, particularly under overt semantic association conditions and that such activation varies in predictable ways. The traditional silent response condition cannot be considered as equivalent to the overt response condition during word generation or semantic association. The multiple-process imaging method introduced here was sensitive to processing robust orthographic, phonological, and semantic regions, particularly under the overt response condition. (author)

Full Text Available Named entity extraction tools designed for recognizing named entities in texts written in standard language (e.g., news stories or legal texts have been shown to be inadequate for user-generated textual content (e.g., tweets, forum posts. In this work, we propose a supervised approach to named entity recognition and classification for Croatian tweets. We compare two sequence labelling models: a hidden Markov model (HMM and conditional random fields (CRF. Our experiments reveal that CRF is the best model for the task, achieving a very good performance of over 87% micro-averaged F1 score. We analyse the contributions of different feature groups and influence of the training set size on the performance of the CRF model.

Mental and behavioral disorders account for about one third of the world's disability caused by all ill health among adults, with unipolar depressive disorders set to be the world's number one cause of illhealth and premature death in 2030, affecting high- and low-income countries. There is a range of evidence-based cost-effective interventions that can be implemented in parenting, at schools, at the workplace, and in older age that can promote health and well-being, reduce mental disorders, lead to improved productivity, and increase resilience to cope with many of the stressors in the world. These facts need to be better communicated to policymakers to ensure that the silent burden of impaired mental health is adequately heard and reduced.

Translation of information from English is an essential step toward ensuring the involvement of non-English speakers in global events. The NameExoWorlds competition, led by the International Astronomical Union (IAU), was held from 9 July 2014 to 15 December 2015. It was a unique event that invited the public to name celestial bodies. In Japan, language acts as a significant barrier for amateur astronomers and school students to participate in global events hosted in English. To address this concern, we established a domestic working group to set up a Japanese website and provided a translation of the IAU's official site for the NameExoWorlds competition. We also developed additional original information in Japanese when needed and sent announcements to a mailing lists of astronomy societies in Japan. As a result, 28% of the registered groups and 47% of proposals for names were from Japan, making Japan the most active country for these stages of the competition. After the competition had ended, we carried out a survey in the Japanese astronomy community and received 124 responses. We found that most of the Japanese participants referred to our official Japanese website in order to overcome the language barrier and participate in the competition. This article explores our work of translating the competition information into Japanese and our evaluation of the impact of this action on the uptake by Japanese astronomy enthusiasts.

Female’s Silent Resistance against Hegemony in The Scarlet Letter, Bekisar Merah, and Belantik: A Comparative Analysis

Directory of Open Access Journals (Sweden)

Full Text Available Social patriarchy is a gender-biased hegemonic value that is structured for the benefits of men but unfortunately disadvantages women. Lasiyah, the protagonist of Bekisar Merah and Belantik, and Hester Prynne, the protagonist of The Scarlet Letter, experienced those hegemonic values that were oppressive, from their patriarchal societies i.e. Java and Puritans. By using the theories of both Hegemony and Comparative Literature, this discussion reveals the two protagonists’ similar silent resistance against the hegemonic values in that this brought them to become new persons with new personality and identity. They were similarly reborn. Both women had comparable factors driving them to conduct silent resistance: pride, dignity, and love. Woman, who is in general considered weak and powerless, is in fact strong and powerful.

Naming is a complex, multi-level process. It is composed of distinct semantic and phonological levels. Children with naming deficits produce different error types when failing to retrieve the target word. This study explored the error characteristics of children with language impairment compared to those with typical language development. 46 preschool children were tested on a naming test: 16 with language impairment and a naming deficit and 30 with typical language development. The analysis compared types of error in both groups. In a group level, children with language impairment produced different error patterns compared to the control group. Based on naming error analysis and performance on other language tests, two case studies of contrasting profiles suggest different sources for lexical retrieval difficulties in children. The findings reveal differences between the two groups in naming scores and naming errors, and support a qualitative impairment in early development of children with naming deficits. The differing profiles of naming deficits emphasise the importance of including error analysis in the diagnosis.

North-American norms for name disagreement: pictorial stimuli naming discrepancies.

Directory of Open Access Journals (Sweden)

Mary O'Sullivan

Full Text Available Pictorial stimuli are commonly used by scientists to explore central processes; including memory, attention, and language. Pictures that have been collected and put into sets for these purposes often contain visual ambiguities that lead to name disagreement amongst subjects. In the present work, we propose new norms which reflect these sources of name disagreement, and we apply this method to two sets of pictures: the Snodgrass and Vanderwart (S&V set and the Bank of Standardized Stimuli (BOSS. Naming responses of the presented pictures were classified within response categories based on whether they were correct, incorrect, or equivocal. To characterize the naming strategy where an alternative name was being used, responses were further divided into different sub-categories that reflected various sources of name disagreement. Naming strategies were also compared across the two sets of stimuli. Results showed that the pictures of the S&V set and the BOSS were more likely to elicit alternative specific and equivocal names, respectively. It was also found that the use of incorrect names was not significantly different across stimulus sets but that errors were more likely caused by visual ambiguity in the S&V set and by a misuse of names in the BOSS. Norms for name disagreement presented in this paper are useful for subsequent research for their categorization and elucidation of name disagreement that occurs when choosing visual stimuli from one or both stimulus sets. The sources of disagreement should be examined carefully as they help to provide an explanation of errors and inconsistencies of many concepts during picture naming tasks.

Improved vocabulary production after naming therapy in aphasia: can gains in picture naming generalize to connected speech?

). These were placed in a larger cohort of verb and noun sets for therapy. Post-therapy assessments examined naming accuracy and speed of target items in single-word picture-naming and naming accuracy in connected speech contexts. There was a step-wise decrement in naming accuracy over the three naming contexts following targeted therapy. Simple pictures elicited the most correct names, followed by picture-supported narratives and lastly unsupported narratives. Picture-naming accuracy significantly predicted naming in the connected speech contexts for the group as a whole. The speed of picture naming after therapy did not predict the extent to which items were named in composite picture description and narrative tasks. The findings suggest that gains in naming accuracy obtained through picture-naming therapy may generalize to naming of the same items in more linguistically and cognitively demanding connected speech tasks. Demonstrating this generalization is methodologically challenging and the method utilized in this study may serve as one starting point for gathering a larger database in order to answer the question posed by this paper more robustly.

Full Text Available En coincidencia con el centenario en 2012 de los legendarios Estudios Universal, este trabajo propone un exhaustivo análisis crítico sobre la construcción de sus principales símbolos terroríficos, la mayoría inspirados en la literatura, que entre los años 1923 y 1941 conformaron la estructura mitogénica del denominado “monstruo clásico”. Tanto en la etapa silente, como con la irrupción del sonoro, las películas de terror de la Universal marcaron un paso imprescindible en la evolución de este género canónico, y a ellas se debe buena parte del ingente desarrollo posterior del mismo.In coincidence with 2012 legendary Universal Studio´s centenary, this paper proposes an exhaustive critical analysis on the construction of its principal terrifying symbols, the majority inspired by literature, which between 1923 and 1941 shaped the myth structure of the so-called "classic monster". In both stages, silent and sonorous movies, the terror of Universal Studios marked an indispensable step in the evolution of this canonical genre, and to them it is owed a good deal of its enormous later development.

The main purpose of this paper is to present some general observations, regularities and insights into a complex relationship between plants and people through symbolic systems like geographical names on the territory of Croatia. The basic sources of data for this research were maps from atlas of Croatia of the scale 1:100000. Five groups of maps or areas were selected in order to represent main Croatian phytogeographic regions. A selection of toponyms from each of the map was made in which the name for a plant in Croatian language was recognized (phytotoponyms). Results showed that of all plant names recognized in geographical names the most represented are trees, and among them birch and oak the most. Furthermore, an attempt was made to explain the presence of the most represented plant species in the phytotoponyms in the light of general phytogeographical and sociocultural differences and similarities of comparing areas. The findings confirm an expectation that the genera of climazonal vegetation of particular area are the most represented among the phytotoponyms. Nevertheless, there are ample examples where representation of a plant name in the names of human environment can only be ascribed to ethno-linguistic and socio-cultural motives. Despite the reductionist character of applied methodology, this research also points out some advantages of this approach for ethnobotanic and ethnolinguistic studies of greater areas of human environment.

Vocabulary learning reflects the language experiences of the child, both in typical and atypical development, although the vocabulary development of children who use aided communication may differ from children who use natural speech. This study compared the performance of children using aided communication with that of peers using natural speech on two measures of vocabulary knowledge: comprehension of graphic symbols and labeling of common objects. There were 92 participants not considered intellectually disabled in the aided group. The reference group consisted of 60 participants without known disorders. The comprehension task consisted of 63 items presented individually in each participant's graphic system, together with four colored line drawings. Participants were required to indicate which drawing corresponded to the symbol. In the expressive labelling task, 20 common objects presented in drawings had to be named. Both groups indicated the correct drawing for most of the items in the comprehension tasks, with a small advantage for the reference group. The reference group named most objects quickly and accurately, demonstrating that the objects were common and easily named. The aided language group named the majority correctly and in addition used a variety of naming strategies; they required more time than the reference group. The results give insights into lexical processing in aided communication and may have implications for aided language intervention.

Full Text Available Microorganisms form diverse multispecies communities in various ecosystems. The high abundance of fungal and bacterial species in these consortia results in specific communication between the microorganisms. A key role in this communication is played by secondary metabolites (SMs, which are also called natural products. Recently, it was shown that interspecies ‘talk’ between microorganisms represents a physiological trigger to activate silent gene clusters leading to the formation of novel SMs by the involved species. This review focuses on mixed microbial cultivation, mainly between bacteria and fungi, with a special emphasis on the induced formation of fungal SMs in co-cultures. In addition, the role of chromatin remodeling in the induction is examined, and methodical perspectives for the analysis of natural products are presented. As an example for an intermicrobial interaction elucidated at the molecular level, we discuss the specific interaction between the filamentous fungi Aspergillus nidulans and Aspergillus fumigatus with the soil bacterium Streptomyces rapamycinicus, which provides an excellent model system to enlighten molecular concepts behind regulatory mechanisms and will pave the way to a novel avenue of drug discovery through targeted activation of silent SM gene clusters through co-cultivations of microorganisms.

Hypertension induced by nitric oxide synthase inhibition is associated with functional abnormalities of the heart and kidney. The aim of the present study was to investigate whether chronic treatment with Arbutus unedo leaf (AuL) or root (AuR) aqueous extracts can prevent these alterations. Six groups of rats were used: control group received tap water; N(G)-nitro-l-arginine methyl-ester (L-NAME) group treated with L-NAME at 40 mg/kg/day; AuL and AuR groups received simultaneously L-NAME (40 mg/kg/day) and Au leaves or roots extract at the same concentration 250 mg/kg/day; l-arginine and enalapril groups received simultaneously L-NAME (40 mg/kg/day) and l-arginine at 50mg/kg/day or enalapril at 15 mg/kg/day. Treatment of rats during 4 weeks with L-NAME caused an increase of the systolic blood pressure (SBP) accompanied by a ventricular hypertrophy, an impairment of endothelium-dependent vasorelaxation, an increase of the cardiac baroreflex sensitivity and a decrease of water, sodium and potassium excretion. The co-administration of AuL or AuR extracts with L-NAME reduces the development of increased SBP, ameliorates the vascular reactivity as well as the baroreflex sensitivity and normalizes the renal function. AuR reduces the ventricular hypertrophy but AuL do not. Enalapril associated with L-NAME reverses the majority of alterations induced by L-NAME while l-arginine only lightly ameliorates the vascular reactivity. These results show that chronic treatment with Arbutus extract regress the development of hypertension and ameliorate cardiovascular and renal functions in NO deficient hypertension.

Widespread use of generic drugs is considered to be indispensable if reductions in total health care costs are to be achieved, but the market share of such drugs remains low. In general, generic drugs have the same active ingredients as brand-name drugs, but this is not always the case. Thus, toxicity profiles may vary when brand-name and generic drugs are compared. We retrospectively investigated the incidence of hyponatremia in patients receiving brand-name cisplatin (CDDP) and a generic counterpart thereof. We reviewed the medical records of patients treated with brand-name CDDP (n=53) and a generic formulation (n=26), and compared the incidences of hyponatremia and renal toxicity. Toxicities were graded using the Common Terminology Criteria for Adverse Events, version 4.0. Differences between groups were evaluated using the Student's t-test, and the odds ratio for hyponatremia was estimated via logistic regression analysis. Serum creatinine levels after chemotherapy increased significantly in both the brand-name and generic CDDP groups; no significant difference was evident between the two groups. Hyponatremia of grade 3 or above developed in 30.7% of the generic CDDP group compared to 15.1% of the brand-name CDDP group (P=0.011). Multivariate analysis showed that the use of generic CDDP increased the incidence of hyponatremia (odds ratio =5.661, 95% confidence interval =1.403-22.839; P=0.015). Oncologists should be aware that use of a generic CDDP might be associated with more hyponatremia than would use of brand-name CDDP.

Plasma destruction of toxins, and volatile organic compounds in particular, from gas streams is receiving increased attention as an energy efficient means to remediate those compounds. In this regard, remediation of trichloroethylene (TCE) in silent discharge plasmas has been experimentally and theoretically investigated. We found that TCE can be removed from Ar/O 2 gas streams at atmospheric pressure with an energy efficiency of 15--20 ppm/(mJ/cm 3 ), or 2--3 kW h kg -1 . The majority of the Cl from TCE is converted to HCl, Cl 2 , and COCl 2 , which can be removed from the gas stream by a water bubbler. The destruction efficiency of TCE is smaller in humid mixtures compared to dry mixtures due to interception of reactive intermediates by OH radicals

Silent cerebral lesions (SCLs) are a potential complication of left atrial radiofrequency ablation (RFA) procedures for paroxysmal atrial fibrillation (PAF). We aimed to compare the incidence of SCLs in patients treated with irrigated RFA multielectrode catheters (nMARQ ® Catheter group) and irrigated focal RFA catheters (NAVISTAR ® THERMOCOOL ® Catheter; TC group) after PAF ablation from subpopulation neurological assessment (SNA) cohorts of the REVOLUTION and reMARQable studies. Data from SNA cohorts in the prospective, nonrandomized REVOLUTION study (March 2011-September 2013) and the prospective, randomized, controlled reMARQable study (October 2013-November 2015) were included. The incidence of SCLs was assessed pre- and postablation using magnetic resonance imaging. Neurological deficits were assessed using the National Institutes of Health Stroke Scale, modified Rankin Scale, and Montreal Cognitive Assessment. A total of 37 patients from REVOLUTION and 76 patients from reMARQable were included in the SNA cohort of each study. In the REVOLUTION SNA cohort, the incidence of SCLs was 21.1% (4/19) in the nMARQ ® Catheter group and 5.9% (1/17) in the TC group. Findings from REVOLUTION helped inform the reMARQable study protocol's stringent anticoagulation regimen. SCL incidence was subsequently reduced in both groups (nMARQ ® Catheter, 7.9%; TC, 3.3%). No permanent neurological deficits were observed. Adherence to a stringent anticoagulation regimen prior to and during ablation procedures appears to be an important factor in minimizing the risk of SCL. © 2017 Wiley Periodicals, Inc.

This report presents a collection of models and control strategies developed and implemented in the power system simulation tool PowerFactory DIgSILENT for different wind turbine concepts. It is the second edition of Risoe-R-1400(EN) and it gathers and describes a whole wind turbine model database built-op and developed during several national research projects, carried out at Risoe DTU National Laboratory for Sustainable Energy and Aalborg University, in the period 2001-2007. The overall objective of these projects was to create a wind turbine model database able to support the analysis of the interaction between the mechanical structure of the wind turbine and the electrical grid during different operational modes. The report provides thus a description of the wind turbines modelling, both at a component level and at a system level. The report contains both the description of DIgSILENT built-in models for the electrical components of a grid connected wind turbine (e.g. induction generators, power converters, transformers) and the models developed by the user, in the dynamic simulation language DSL of DIgSILENT, for the non-electrical components of the wind turbine (wind model, aerodynamic model, mechanical model). The initialisation issues on the wind turbine models into the power system simulation are also presented. The main attention in the report is drawn to the modelling at the system level of the following wind turbine concepts: (1) Fixed speed active stall wind turbine concept (2) Variable speed doubly-fed induction generator wind turbine concept (3) Variable speed multi-pole permanent magnet synchronous generator wind turbine concept These wind turbine concept models can be used and even extended for the study of different aspects, e.g. the assessment of power quality, control strategies, connection of the wind turbine at different types of grid and storage systems. Different control strategies have been developed and implemented for these wind turbine

Cross-border cholera outbreaks are a major public health problem in Sub-Saharan Africa contributing to the high annual reported cholera cases and deaths. These outbreaks affect all categories of people and are challenging to prevent and control. This article describes lessons learnt during the cross-border cholera outbreak control in Eastern and Southern Africa sub-regions using the case of Uganda-DRC and Malawi-Mozambique borders and makes recommendations for future outbreak prevention and control. We reviewed weekly surveillance data, outbreak response reports and documented experiences on the management of the most recent cross-border cholera outbreaks in Eastern and Southern Africa sub-regions, namely in Uganda and Malawi respectively. Uganda-Democratic Republic of Congo and Malawi-Mozambique borders were selected because the countries sharing these borders reported high cholera disease burden to WHO. A total of 603 cross-border cholera cases with 5 deaths were recorded in Malawi and Uganda in 2015. Uganda recorded 118 cases with 2 deaths and CFR of 1.7%. The under-fives and school going children were the most affected age groups contributing 24.2% and 36.4% of all patients seen along Malawi-Mozambique and Uganda-DRC borders, respectively. These outbreaks lasted for over 3 months and spread to new areas leading to 60 cases with 3 deaths, CRF of 5%, and 102 cases 0 deaths in Malawi and Uganda, respectively. Factors contributing to these outbreaks were: poor sanitation and hygiene, use of contaminated water, floods and rampant cross-border movements. The outbreak control efforts mainly involved unilateral measures implemented by only one of the affected countries. Cross-border cholera outbreaks contribute to the high annual reported cholera burden in Sub-Saharan Africa yet they remain silent, marginalized and poorly identified by cholera actors (governments and international agencies). The under-fives and the school going children were the most affected age

However, for the layman the sudden profusion of new...

Theriocide: Naming Animal Killing

Directory of Open Access Journals (Sweden)

Piers Beirne

2014-08-01

Full Text Available In this essay I recommend ‘theriocide’ as the name for those diverse human actions that cause the deaths of animals. Like the killing of one human by another, theriocide may be socially acceptable or unacceptable, legal or illegal. It may be intentional or unintentional and may involve active maltreatment or passive neglect. Theriocide may occur one-on-one, in small groups or in large-scale social institutions. The numerous and sometimes intersecting sites of theriocide include intensive rearing regimes; hunting and fishing; trafficking; vivisection; militarism; pollution; and human-induced climate change. If the killing of animals by humans is as harmful to them as homicide is to humans, then the proper naming of such deaths offers a remedy, however small, to the extensive privileging of human lives over those of other animals. Inevitably, the essay leads to a shocking question: Is theriocide murder?

Activation of the Silent Secondary Metabolite Production by Introducing Neomycin-Resistance in a Marine-Derived Penicillium purpurogenum G59

Directory of Open Access Journals (Sweden)

Chang-Jing Wu

2015-04-01

Full Text Available Introduction of neomycin-resistance into a marine-derived, wild-type Penicillium purpurogenum G59 resulted in activation of silent biosynthetic pathways for the secondary metabolite production. Upon treatment of G59 spores with neomycin and dimethyl sulfoxide (DMSO, a total of 56 mutants were obtained by single colony isolation. The acquired resistance of mutants to neomycin was testified by the resistance test. In contrast to the G59 strain, the EtOAc extracts of 28 mutants inhibited the human cancer K562 cells, indicating that the 28 mutants have acquired the capability to produce bioactive metabolites. HPLC-photodiode array detector (PDAD-UV and HPLC-electron spray ionization (ESI-MS analyses further indicated that diverse secondary metabolites have been newly produced in the bioactive mutant extracts. Followed isolation and characterization demonstrated that five bioactive secondary metabolites, curvularin (1, citrinin (2, penicitrinone A (3, erythro-23-O-methylneocyclocitrinol (4 and 22E-7α-methoxy-5α, 6α-epoxyergosta-8(14,22-dien-3β-ol (5, were newly produced by a mutant, 4-30, compared to the G59 strain. All 1–5 were also not yet found in the secondary metabolites of other wild type P. purpurogenum strains. Compounds 1–5 inhibited human cancer K562, HL-60, HeLa and BGC-823 cells to varying extents. Both present bioassays and chemical investigations demonstrated that the introduction of neomycin-resistance into the marine-derived fungal G59 strain could activate silent secondary metabolite production. The present work not only extended the previous DMSO-mediated method for introducing drug-resistance in fungi both in DMSO concentrations and antibiotics, but also additionally exemplified effectiveness of this method for activating silent fungal secondary metabolites. This method could be applied to other fungal isolates to elicit their metabolic potentials to investigate secondary metabolites from silent biosynthetic pathways.

Background: Dysphagia is a common disorder among patients with Parkinson's disease (PD). It occurs in up to 80% of all (PD) patients during the early stages of the disease and up to 95% in the advanced stages; but professionals may not hear from the patients about dysphagia symptoms until these symptoms reach an advanced stage and lead to medical complications. Materials and Methods: Thirty-three PD patients (mean age 66.09 ± 9.4 years; 24 men, nine women) participated in this study at our Neurology Institute, between April 20, 2013, and October 26, 2013. They were asked two questions; one about saliva control and the other about silent saliva penetration and aspiration. Next, they underwent the videofluoroscopic swallowing study (VFSS). Results: The Pearson Correlation coefficient between the Penetration–Aspiration Scale (PAS) scores and question 1 scores was 0.48 (P < 0.05, =0.25), and there was a significant correlation between the PAS scores and question 2 scores, and also question 1 scores + question 2 scores (r = 0.589, P < 0.05, =0 and r = 0589, P < 0.05, =0). Conclusions: This study showed a significant correlation between the questions about saliva control, silent saliva penetration, and aspiration, and laryngeal penetration and aspiration during VFSS. Therefore, by using these two questions, the potential silent laryngeal penetration and aspiration during meals could be detected before it led to aspiration pneumonia. Taking the benefit of these questions, as a part of the swallowing assessment of PD patients, is recommended. PMID:26261810

Full Text Available Silent adrenocorticotrophic pituitary adenomas are nonfunctioning pituitary adenomas that express adrenocorticotrophic hormone (ACTH but do not cause the clinical or laboratory features of hypercortisolemia. Primary central nervous system (CNS melanoma is well documented, but rarely originates in the sellar region or pituitary gland. Here we report transformation of an aggressive silent adrenocorticotrophic pituitary adenoma that transformed into CNS melanoma and review other presentations of pituitary melanoma. A 37-year-old woman initially presented with apoplexy and an invasive nonfunctioning pituitary macroadenoma for which she underwent transphenoidal surgery. The patient underwent 3 subsequent surgeries as the tumor continued to progress. Pathology from the first 3 operations showed pituitary adenoma or carcinoma. Pathology from the final surgery showed melanoma and the magnetic resonance imaging characteristics of the tumor had changed to become consistent with CNS melanoma. Dermatologic and ophthalmologic examinations did not identify cutaneous or ocular melanoma. The patient’s disease progressed despite aggressive surgical, medical and radiologic treatment. To our knowledge, this is the first report demonstrating transformation of a primary pituitary tumor into melanoma. The mechanism of tumor transformation is unclear, but it is possible that a mutation in the original ACTH-producing tumor lead to increased cleavage of pro-opiomelanocortin or ACTH into α-melanocyte-stimulating hormone, which in turn stimulated the expression of microopthalmia transcription factor, leading to melanocytic phenotype transformation.

2006-02-01

A multilingual, colored-letter synesthete professor (MLS), 9 nonsynesthete multilingual professors and 4 nonsynesthete art professors learned 30 names of individuals (first and last name pairs) in three trials. They recalled the names after each trial and six months later, as well as performed cued recall trials initially and after six months. As hypothesized, MLS recalled significantly more names than control groups on all free recall tests (except after the first trial) and on cued recall tests. In addition, MLS gave qualitatively different reasons for remembering names than any individual control participant. MLS gave mostly color reasons for remembering the names, whereas nonsynesthetes gave reasons based on familiarity or language or art knowledge. Results on standardized memory tests showed that MLS had average performance on non-language visual memory tests (the Benton Visual Retention Test-Revised--BURT-R, and the Rey-Osterrieth Complex Figure Test--CFT), but had superior memory performance on a verbal test consisting of lists of nouns (Rey Auditory-Verbal Learning Test--RAVLT). MLS's synesthesia seems to aid memory for visually or auditorily presented language stimuli (names and nouns), but not for non-language visual stimuli (simple and complex figures).

Major-element geochemistry of the Silent Canyon--Black Mountain peralkaline volcanic centers, northwestern Nevada Test Site: applications to an assessment of renewed volcanism

International Nuclear Information System (INIS)

Crowe, B.M.; Sargent, K.A.

1979-01-01

The Silent Canyon and Black Mountain volcanic centers are located in the northern part of the Nevada Test Site. The Silent Canyon volcanic center is a buried cauldron complex of Miocene age (13 to 15 m.y.). Black Mountain volcanic center is an elliptical-shaped cauldron complex of late Miocene age. The lavas and tuffs of the two centers comprise a subalkaline-peralkaline association. Rock types range from quartz normative subalkaline trachyte and rhyolite to peralkaline commendite. The Gold Flat Member of the Thirsty Canyon Tuff (Black Mountain) is a pantellerite. The major-element geochemistry of the Black Mountain--Silent Canyon volcanic centers differ in the total range and distribution of SiO 2 , contents, the degree of peralkalinity (molecular Na 2 O + K 2 O > Al 2 O 3 ) and in the values of total iron and alumina through the range of rock types. These differences indicate that the suites were unrelated and evolved from differing magma bodies. The Black Mountain volcanic cycle represents a renewed phase of volcanism following cessation of the Timber Mountain--Silent Canyon volcanic cycles. Consequently, there is a small but numerically incalculable probability of recurrence of Black Mountain-type volcanism within the Nevada Test Site region. This represents a potential risk with respect to deep geologic storage of high-level radioactive waste at the Nevada Test Site

The 2 studies reported in this manuscript collectively address 3 aims: (a) to characterize the name-writing abilities of preschool-age children with language impairment (LI), (b) to identify those emergent literacy skills that are concurrently associated with name-writing abilities, and (c) to compare the name-writing abilities of children with LI to those of their typical language (TL) peers. Fifty-nine preschool-age children with LI were administered a battery of emergent literacy and language assessments, including a task in which the children were asked to write their first names. A subset of these children (n=23) was then compared to a TL-matched sample to characterize performance differences. Results showed that the name-writing abilities of preschoolers with LI were associated with skills in alphabet knowledge and print concepts. Hierarchical multiple regression analysis indicated that only alphabet knowledge uniquely contributed to the variance in concurrent name-writing abilities. In the matched comparison, the TL group demonstrated significantly more advanced name-writing representations than the LI group. Children with LI lag significantly behind their TL peers in name-writing abilities. Speech-language pathologists are encouraged to address the print-related skills of children with LI within their clinical interventions.

Parents accidentally substitute similar sounding sibling names more often than dissimilar names.

Directory of Open Access Journals (Sweden)

Zenzi M Griffin

Full Text Available When parents select similar sounding names for their children, do they set themselves up for more speech errors in the future? Questionnaire data from 334 respondents suggest that they do. Respondents whose names shared initial or final sounds with a sibling's reported that their parents accidentally called them by the sibling's name more often than those without such name overlap. Having a sibling of the same gender, similar appearance, or similar age was also associated with more frequent name substitutions. Almost all other name substitutions by parents involved other family members and over 5% of respondents reported a parent substituting the name of a pet, which suggests a strong role for social and situational cues in retrieving personal names for direct address. To the extent that retrieval cues are shared with other people or animals, other names become available and may substitute for the intended name, particularly when names sound similar.

To characterize the performance of Brazilian students exposed to two languages in reading fluency, phonological memory, and rapid naming, according to grade level, and to investigate correlations between these variables. Sixty students took part in this study (50% female), enrolled in the third to the fifth grades of two elementary schools of the city of São Paulo. They constituted two groups - bilingual group: 30 Brazilian children whose mother tongue and language spoken at home was Brazilian Portuguese and who were daily exposed to English at school for a period not shorter than three years; monolingual group: 30 students, from a monolingual Brazilian elementary school, who were paired by gender, age, and grade level with the bilingual students. Foreign children, children with complaint or indication of speech and language disorder, or who had been retained were excluded. A rapid automatized naming, pseudoword repetition, and oral reading tests were administered. The bilingual children were assessed in both languages and their performances were compared among themselves and with the monolingual group, which was only assessed in Brazilian Portuguese. The bilingual group showed better performance in English, rapid naming, and pseudoword repetition tasks, whereas Brazilian Portuguese, in reading fluency. A higher number of correlations were found in Brazilian Portuguese. The results suggest that the acquisition of a second language may positively influence the abilities of rapid naming, reading rate, and accuracy. Brazilian bilingual students performed better in tasks of phonological memory in English and Brazilian Portuguese performed better in reading fluency. Different correlation patterns were found between the rapid naming, accuracy, and reading rate, in the bilingual group analysis, in both languages.

Chlamydia pneumoniae hides inside apoptotic neutrophils to silently infect and propagate in macrophages.

Directory of Open Access Journals (Sweden)

Jan Rupp

Full Text Available BACKGROUND: Intracellular pathogens have developed elaborate strategies for silent infection of preferred host cells. Chlamydia pneumoniae is a common pathogen in acute infections of the respiratory tract (e.g. pneumonia and associated with chronic lung sequelae in adults and children. Within the lung, alveolar macrophages and polymorph nuclear neutrophils (PMN are the first line of defense against bacteria, but also preferred host phagocytes of chlamydiae. METHODOLOGY/PRINCIPAL FINDINGS: We could show that C. pneumoniae easily infect and hide inside neutrophil granulocytes until these cells become apoptotic and are subsequently taken up by macrophages. C. pneumoniae infection of macrophages via apoptotic PMN results in enhanced replicative activity of chlamydiae when compared to direct infection of macrophages, which results in persistence of the pathogen. Inhibition of the apoptotic recognition of C. pneumoniae infected PMN using PS- masking Annexin A5 significantly lowered the transmission of chlamydial infection to macrophages. Transfer of apoptotic C. pneumoniae infected PMN to macrophages resulted in an increased TGF-ss production, whereas direct infection of macrophages with chlamydiae was characterized by an enhanced TNF-alpha response. CONCLUSIONS/SIGNIFICANCE: Taken together, our data suggest that C. pneumoniae uses neutrophil granulocytes to be silently taken up by long-lived macrophages, which allows for efficient propagation and immune protection within the human host.

This critical review of the literature regarding the recovery experiences and healthcare needs of people under 60 following a fragility hip fracture seeks to identify the associated implications for nursing practice and inform care delivery. Forty papers were included following a structured database, citation and grey literature search and filtering of results in line with specified inclusion criteria. Hip fracture is a common, serious and complex injury and an important cause of morbidity, mortality and rising healthcare costs worldwide. This review indicates that although commonly associated with the elderly, incidence and impact in the under 60s has been under-explored. Current health policy, professional and social norms almost exclusively focus on the elderly, surgical interventions and short-term outcomes, rendering the under 60s an inadvertently marginalised, relatively 'silent' sub-set of the hip fracture population. Nurses must be aware, however, of the different recovery needs of this younger group. The limited evidence available indicates these include work related needs and long term physical and psychosocial limitations in this socially and economically active group. Priorities are identified for research to inform policy and practice. Meanwhile, nurses can address the needs of this group by listening to and involving them and their families as healthcare partners. Copyright © 2018. Published by Elsevier Ltd.

Rtt107/Esc4 binds silent chromatin and DNA repair proteins using different BRCT motifs

Jockusch Rebecca A

2006-11-01

Full Text Available Abstract Background By screening a plasmid library for proteins that could cause silencing when targeted to the HMR locus in Saccharomyces cerevisiae, we previously reported the identification of Rtt107/Esc4 based on its ability to establish silent chromatin. In this study we aimed to determine the mechanism of Rtt107/Esc4 targeted silencing and also learn more about its biological functions. Results Targeted silencing by Rtt107/Esc4 was dependent on the SIR genes, which encode obligatory structural and enzymatic components of yeast silent chromatin. Based on its sequence, Rtt107/Esc4 was predicted to contain six BRCT motifs. This motif, originally identified in the human breast tumor suppressor gene BRCA1, is a protein interaction domain. The targeted silencing activity of Rtt107/Esc4 resided within the C-terminal two BRCT motifs, and this region of the protein bound to Sir3 in two-hybrid tests. Deletion of RTT107/ESC4 caused sensitivity to the DNA damaging agent MMS as well as to hydroxyurea. A two-hybrid screen showed that the N-terminal BRCT motifs of Rtt107/Esc4 bound to Slx4, a protein previously shown to be involved in DNA repair and required for viability in a strain lacking the DNA helicase Sgs1. Like SLX genes, RTT107ESC4 interacted genetically with SGS1; esc4Δ sgs1Δ mutants were viable, but exhibited a slow-growth phenotype and also a synergistic DNA repair defect. Conclusion Rtt107/Esc4 binds to the silencing protein Sir3 and the DNA repair protein Slx4 via different BRCT motifs, thus providing a bridge linking silent chromatin to DNA repair enzymes.

Full Text Available Lysophosphatidic acid (LPA, which is proposed to play an important role in normal physiological situations such as wound healing, vascular tone, vascular integrity and reproduction, may be involved in the etiology of some diseases such as atherosclerosis, cancer, obesity or myocardial infarction. Abnormal findings, including silent brain infarction (SBI, are frequently observed by magnetic resonance imaging (MRI in patients with nonvalvular atrial fibrillation (NVAF. However, whether there is a relationship between LPA level and the prevalence of SBI has not been extensively studied. In the present study, the association between them was investigated. 235 patients with NVAF, 116 cases of SBI without NVAF and 120 cases of healthy volunteers (control group, who did not receive any antithrombotic therapy, were enrolled in this study. Plasma LPA levels in the NVAF with SBI group were significantly higher than that in the control group (p < 0.01, NVAF without SBI group (p < 0.01 and SBI without NVAF group (p < 0.01. The LPA levels are lower in the control group than in the NVAF without SBI and SBI without NVAF groups (p < 0.01, however, the latter two groups did not significantly differ from each other for LPA levels (p > 0.05 There were significant differences in the positive rate of platelet activation between each of the groups (p < 0.01. The positive rate of platelet activation was significantly higher in the NVAF with SBI group. We suggest that LPA might be a novel marker for estimation of the status of platelet activation and the risk factor for SBI onset in NVAF patients. We expected that plasma LPA levels could predict the occurrence of SBI in NVAF patients.

2016-12-01

During 2013/14, Israel witnessed the silent reintroduction and sustained transmission of wild poliovirus type 1 (WPV1) detected through routine environmental surveillance performed on sewage samples. The public health response to silent poliovirus transmission in a population with high inactivated polio vaccine (IPV) coverage poses an emerging challenge towards the 'End Game' of global poliovirus eradication. This paper reviews the risk assessment, risk management and risk communication aspects of this poliovirus incident. Special emphasis is placed on the use of scientific data generated in the risk assessment phase to inform the public health response. Reintroducing a live vaccine in supplemental immunization activities in response to transmission of WPV or vaccine-derived poliovirus should be considered close to the 'End Game' of polio eradication, especially if targeting the population at risk is feasible. Such circumstances require a comprehensive contingency plan that will support the generation of important public health evidence at the risk assessment stage, thereby allowing to tailor the risk management approaches and underpin appropriate risk communication.

Silent Majority, Violent Majority: The Counter-Revolution in 70s Cinema

Peter Andrew Novick

2012-12-01

Full Text Available «There is one question, Inspector Callahan: Why do they call you ‘Dirty Harry’?» Harry, it is explained, «…Hates everybody: Limeys, Micks, Hebes, Fat Degos, Niggers, Honkies, Chinks…especially Spics». Don Siegel’s Dirty Harry (1971, famously labeled «fascist» by prominent film critic Pauline Kael, nonetheless represented something new and unique—the “Silent Majority’s” entry into liberal New Hollywood, a veritable counter-reformation to the new social movements having sprung up in the late Sixties and early Seventies. Far from the traditional American Right, however, and distinctly un-Fascist (in as much as the term means more than a simple epithet, these films acted to unite traditional European philosophy and revolutionary thought with organic conservative American tendencies, resulting in hybrid films which challenged the new social movements, while working within the medium of liberal New American Cinema. The article will address three themes from the era: violence and race in the city, revenge against “liberated women”, and fear and loathing of homosexuality. In each instance, using primary evidence from films and critical reviews from the Seventies and the present era, in addition to American and European theorists, the article will show how the counter-revolution in Seventies cinema failed to expunge the “revolutionary spirit” of the era. Rather, the Silent Majority’s visions of visual violence and reactionary values became part and parcel of the new liberated culture of the “Me Decade,” forever bounding the conservative celluloid revolt to the new cinematic culture.

The concept of ‘clinical expertise’ is described as a part of evidence-based practice (EBP) together with ‘external scientific evidence’ and ‘patient values and perspectives’. However, clinical expertise in the management of voice disorders has not been described or discussed in much detail....... The expertise seems to consist partly of silent know-how that, from the outside, may seem improperly related to the personality of the speech-language pathologist or exclusively dependent on the number of years in the field. In this paper, it is suggested that clinical expertise in voice therapy consists...

The contribution of discrete-trial naming and visual recognition to rapid automatized naming deficits of dyslexic children with and without a history of language delay

2014-09-01

Full Text Available Children with Developmental Dyslexia (DD are impaired in Rapid Automatized Naming (RAN tasks, where subjects are asked to name arrays of high frequency items as quickly as possible. However the reasons why RAN speed discriminates DD from typical readers are not yet fully understood. Our study was aimed to identify some of the cognitive mechanisms underlying RAN-reading relationship by comparing one group of 32 children with DD with an age-matched control group of typical readers on a naming and a visual recognition task both using a discrete-trial methodology , in addition to a serial RAN task, all using the same stimuli (digits and colors. Results showed a significant slowness of DD children in both serial and discrete-trial naming tasks regardless of type of stimulus, but no difference between the two groups on the discrete-trial recognition task. Significant differences between DD and control participants in the RAN task disappeared when performance in the discrete-trial naming task was partialled out by covariance analysis for colors, but not for digits. The same pattern held in a subgroup of DD subjects with a history of early language delay (LD. By contrast, in a subsample of DD children without LD the RAN deficit was specific for digits and disappeared after slowness in discrete-trial naming was partialled out. Slowness in discrete-trial naming was more evident for LD than for noLD DD children. Overall, our results confirm previous evidence indicating a name-retrieval deficit as a cognitive impairment underlying RAN slowness in DD children. This deficit seems to be more marked in DD children with previous LD. Moreover, additional cognitive deficits specifically associated with serial RAN tasks have to be taken into account when explaining deficient RAN speed of these latter children. We suggest that partially different cognitive dysfunctions underpin superficially similar RAN impairments in different subgroups of DD subjects.

Full Text Available Background: Dysphagia is a common disorder among patients with Parkinson′s disease (PD. It occurs in up to 80% of all (PD patients during the early stages of the disease and up to 95% in the advanced stages; but professionals may not hear from the patients about dysphagia symptoms until these symptoms reach an advanced stage and lead to medical complications. Materials and Methods: Thirty-three PD patients (mean age 66.09 ± 9.4 years; 24 men, nine women participated in this study at our Neurology Institute, between April 20, 2013, and October 26, 2013. They were asked two questions; one about saliva control and the other about silent saliva penetration and aspiration. Next, they underwent the videofluoroscopic swallowing study (VFSS. Results: The Pearson Correlation coefficient between the Penetration-Aspiration Scale (PAS scores and question 1 scores was 0.48 (P < 0.05, =0.25, and there was a significant correlation between the PAS scores and question 2 scores, and also question 1 scores + question 2 scores (r = 0.589, P < 0.05, =0 and r = 0589, P < 0.05, =0. Conclusions: This study showed a significant correlation between the questions about saliva control, silent saliva penetration, and aspiration, and laryngeal penetration and aspiration during VFSS. Therefore, by using these two questions, the potential silent laryngeal penetration and aspiration during meals could be detected before it led to aspiration pneumonia. Taking the benefit of these questions, as a part of the swallowing assessment of PD patients, is recommended.

1992-07-01

The number of underperfused myocardial segments, the extent of coronary artery disease and the severity of impairment of coronary flow reserve were compared in 147 consecutive patients exhibiting painful or painless ischaemic ST segment depression on exercise testing. Of 147 patients, only 61 (41%) experienced angina (group 1) whilst 86 (59%) did not (group 2). In the two groups coronary disease was comparable for both extent and distribution, and neither the location of transient perfusion defects nor their relation to areas of old myocardial necrosis appeared to influence the presence or absence of chest pain. However, exercise duration, exercise time and rate-pressure product at the beginning of ischaemia were lower in group 1. Furthermore, a greater proportion of asymptomatic patients had only one ischaemic segment on 99mTc-MIBI perfusion scintigraphy. We conclude that: (1) in patients with effort angina and coronary disease, the incidence of electrocardiographic silent ischaemic events induced by exercise is similar to that observed in studies based on continuous ECG monitoring. (2) Exertional angina is more frequently associated with greater ischaemic areas and with more severe degrees of impairment of residual coronary flow reserve. (3) The presence of an old myocardial infarction does not appear to influence the incidence of ischaemic cardiac pain.

Silent electrical discharges are used to produce highly reactive free radicals that destroy hazardous compounds entrained in gaseous effluents at ambient gas temperatures and pressures. We have carried out destruction experiments at Los Alamos on a range of volatile organic compounds (VOCs), including trichloroethylene (TCE), carbon tetrachloride, perchloroethylene (PCE), and chlorofluorocarbons (CFCs). We have measured a ''nine-factor'', the amount of energy required to reduce the VOC concentration by a factor of ten. For practical reactor power densities, the ''nine-factor'' can be used to predict the destruction an removal efficiency (DRE) in terms of gas flow rate and the number of reactor modules. This report proposes a modular, stackable architecture for scaling up the reactor throughput

What's in a Name? Interlocutors Dynamically Update Expectations about Shared Names.

Gegg-Harrison, Whitney M; Tanenhaus, Michael K

2016-01-01

In order to refer using a name, speakers must believe that their addressee knows about the link between the name and the intended referent. In cases where speakers and addressees learned a subset of names together, speakers are adept at using only the names their partner knows. But speakers do not always share such learning experience with their conversational partners. In these situations, what information guides speakers' choice of referring expression? A speaker who is uncertain about a names' common ground (CG) status often uses a name and description together. This N+D form allows speakers to demonstrate knowledge of a name, and could provide, even in the absence of miscommunication, useful evidence to the addressee regarding the speaker's knowledge. In cases where knowledge of one name is associated with knowledge of other names, this could provide indirect evidence regarding knowledge of other names that could support generalizations used to update beliefs about CG. Using Bayesian approaches to language processing as a guiding framework, we predict that interlocutors can use their partner's choice of referring expression, in particular their use of an N+D form, to generate more accurate beliefs regarding their partner's knowledge of other names. In Experiment 1, we find that domain experts are able to use their partner's referring expression choices to generate more accurate estimates of CG. In Experiment 2, we find that interlocutors are able to infer from a partner's use of an N+D form which other names that partner is likely to know or not know. Our results suggest that interlocutors can use the information conveyed in their partner's choice of referring expression to make generalizations that contribute to more accurate beliefs about what is shared with their partner, and further, that models of CG for reference need to account not just for the status of referents, but the status of means of referring to those referents.

2002-01-01

We surveyed to assess for the incidence of clinically silent brain infarction after cerebral catheter angiography. Diffusion-weighted images were performed shortly after 33 cerebral catheter angiographies. We found totally 11 abnormally high intensity spots in 5 of 33 patients on diffusion-weighted images and, therefore, the incidence was calculated as 15.2%. This incidence is higher than has been estimated based on the incidence of neurological deficits (about 0.5%) after cerebral angiography. Diffusion-weighted MR imaging is suitable to monitor the safety of angiographic procedures and material. (author)

Network-Based Integration of Disparate Omic Data To Identify "Silent Players" in Cancer.

Directory of Open Access Journals (Sweden)

Matthew Ruffalo

2015-12-01

Full Text Available Development of high-throughput monitoring technologies enables interrogation of cancer samples at various levels of cellular activity. Capitalizing on these developments, various public efforts such as The Cancer Genome Atlas (TCGA generate disparate omic data for large patient cohorts. As demonstrated by recent studies, these heterogeneous data sources provide the opportunity to gain insights into the molecular changes that drive cancer pathogenesis and progression. However, these insights are limited by the vast search space and as a result low statistical power to make new discoveries. In this paper, we propose methods for integrating disparate omic data using molecular interaction networks, with a view to gaining mechanistic insights into the relationship between molecular changes at different levels of cellular activity. Namely, we hypothesize that genes that play a role in cancer development and progression may be implicated by neither frequent mutation nor differential expression, and that network-based integration of mutation and differential expression data can reveal these "silent players". For this purpose, we utilize network-propagation algorithms to simulate the information flow in the cell at a sample-specific resolution. We then use the propagated mutation and expression signals to identify genes that are not necessarily mutated or differentially expressed genes, but have an essential role in tumor development and patient outcome. We test the proposed method on breast cancer and glioblastoma multiforme data obtained from TCGA. Our results show that the proposed method can identify important proteins that are not readily revealed by molecular data, providing insights beyond what can be gleaned by analyzing different types of molecular data in isolation.

Cigarette smoking is strongly associated with ischemic heart disease and acute coronary events. The effect of smoking a single cigarette on regional myocardial perfusion was studied in 13 chronic smokers with typical stable angina pectoris using positron emission tomography and rubidium-82 ( 82 Rb). Findings were compared with the effects of physical exercise. After exercise, 8 patients (61%) had angina, ST depression and abnormal regional myocardial perfusion. Uptake of 82 Rb increased from 49 +/- 8 to 60 +/- 7 in remote myocardium, but decreased from 46 +/- 3 to 37 +/- 5 in an ischemic area. The remaining 5 patients (39%) had homogeneous increases in 82 Rb uptake without angina or ST depression. After smoking, 6 of the 8 patients with positive exercise test responses had a decrease in 82 Rb uptake, from 47 +/- 3 to 35 +/- 6 in the same segment of myocardium affected during exercise. However, in contrast to exercise, the events during smoking were largely silent. The absolute decreases in regional 82 Rb uptake after smoking occurred at significantly lower levels of myocardial oxygen demand than after exercise. This suggests that an impairment of coronary blood supply is responsible. Thus, in smokers with coronary artery disease, each cigarette can cause profound silent disturbances of regional myocardial perfusion that are likely to occur frequently during daily life. Such repeated insults may represent an important mechanism linking smoking with coronary events

Optimization of coronary risk evaluation in stroke patients has been encouraged. The relationship between symptomatic intracranial atherosclerosis and occult coronary artery disease (CAD) has not been evaluated sufficiently. We aimed to investigate the prevalence of silent myocardial ischemia in patients with symptomatic intracranial atherosclerosis and to identify factors associated with its presence. From 186 first-ever transient ischemic attack or ischemic stroke patients with intracranial stenoses, 65 fulfilled selection criteria, including angiographic confirmation of a symptomatic atherosclerotic stenosis and absence of known CAD. All patients underwent a maximal-stress myocardial perfusion single-photon emission computed tomography (SPECT). Lipoprotein(a) [Lp(a)], C-reactive protein, and homocysteine (Hcy) levels were determined before SPECT. Stress-rest SPECT detected reversible myocardial perfusion defects in 34 (52%) patients. Vascular risk factors associated with a pathologic SPECT were hypercholesterolemia (P=0.045), presence of >2 risk factors (P=0.004) and high Lp(a) (P=0.023) and Hcy levels (P=0.018). Ninety percent of patients with high Lp(a) and Hcy levels had a positive SPECT. Existence of a stenosed intracranial internal carotid artery (ICA; odds ratio [OR], 7.22, 2.07 to 25.23; P=0.002) and location of the symptomatic stenosis in vertebrobasilar arteries (OR, 4.89, 1.19 to 20.12; P=0.027) were independently associated with silent myocardial ischemia after adjustment by age, sex, and risk factors. More than 50% of the patients with symptomatic intracranial atherosclerosis and not overt CAD show myocardial perfusion defects on stress-rest SPECT. Stenosed intracranial ICA, symptomatic vertebrobasilar stenosis and presence of high Lp(a) and Hcy levels may characterize the patients at a higher risk for occult CAD.

Full Text Available This article provides a preliminary investigation into the naming practices of a unique product group: pyrotechnics. It is conducted through a comprehensive survey of units made available in the UK marketplace (of 2015 during peak seasonal availability (end of October through early November, when fireworks can easily be purchased from non-specialist retailers. The semantic content underpinning effective branding is shown as being predominantly focused on the sensory impact of the explosions, which provides the primary naming impetus. The analysis is conducted through a statistical assessment against thematic grouping — this approach is typical for the statistical assessment of brand names linguistic categorisation. The author introduces a range of twelve thematic categories that correspond to the semantic fields used as the associative basis for each name. This analysis features a dedicated assessment of two specific categories: Rockets (which provide a statistically-representative snapshot of the entire range and Sparklers (which were omitted from the quantitative data. The article shows that most often firework names are retrieved from military and cosmic thematic groups and point mainly to the expected visual effects. Besides providing relevant quantitative data, the paper demonstrates the qualitative linguistic versatility of firework names, arguing that they hold significant analytic opportunities for examining the role of associative semantics in the commercial naming of entertainment products.

Effects of DBS, premotor rTMS, and levodopa on motor function and silent period in advanced Parkinson's disease

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a widely used and highly effective treatment for patients with advanced Parkinson's disease (PD). Repetitive TMS (rTMS) applied to motor cortical areas has also been shown to improve symptoms in PD and modulate motor cortical...... excitability. Here, we compared clinical and neurophysiological effects of STN stimulation with those of 1 Hz rTMS given to the dorsal premotor cortex (PMd) and those following intake of levodopa in a group of PD patients with advanced disease. Ten PD patients were studied on 2 consecutive days before...... and after surgery. Clinical effects were determined using the UPDRS motor score. Motor thresholds, motor-evoked potential (MEP) amplitudes during slight voluntary contraction, and the cortical silent periods (SP) were measured using TMS. Before surgery effects of levodopa and 1 Hz PMd rTMS and after surgery...

Full Text Available This article examines what I call a “system of cooperation” (K. hyŏp’ŏp, J. kyōgyō, 協業 in the colonial Korean film industry from 1923, when silent films appeared, to the late 1930s, when colonial cinema was restructured within an imperial wartime system. In other words, this article examines the interworking of colonial Korean and imperial Japanese cinema from Yun Hae-dong’s “colonial modern” perspective in order to go beyond the long established lens on colonial Korean film and film historiography that merely focused on the contributions of colonial Korean filmmakers. Here the author rather focuses on the cooperation or collaboration between Japan and Korea: Japanese directors and cinematographers working in Korea, Korean filmmakers with experience in the Japanese apprenticeship system, and filmmakers working together and independently during the silent film era. During the transition from the silent to the early talkie eras, second-generation filmmakers, especially those who trained in film studios in Japan, were significant. They dreamed of the corporatization of the colonial Korean film industry and took the lead in coproductions between Japanese film companies and their colonial Korean counterparts. Korean filmmakers were not unilaterally suppressed by imperial Japan, nor did they independently operate within the Korean film industry during the colonial period. The Japanese in colonial Korea did not take the lead in forming the colonial Korean film scene, either. The core formation of colonial Korean / Korean film was a process of Korean and Japanese filmmakers in competition and negotiation with one another within a complex film sphere launched with Japanese capital and technology.

1992-01-01

We investigated the causes and long-term prognosis of exercise-induced silent myocardial ischemia (SMI) by means of exercise Tl-201 myocardial SPECT (Ex-SPECT) in 97 patients with effort angina or old myocardial infarction (OMI). These patients were proven to have significant stenosis by coronary angiography. The subjects were divided into three groups based on the presence or absence of Tl-201 redistribution (RD) or angina during exercise testing. Group one consisted of 34 patients who had RD on Ex-SPECT and angina during exercise testing: the painful myocardial ischemia (PMI) group. The second group consisted of 38 patients who had RD on Ex-SPECT, but no angina during exercise testing: the SMI group. The third group consisted of 25 patients who had no RD: the RD (-) group. The ischemic range and intensity were quantified by the defect volume ratio (DVR) and defect severity index (DSI), respectively. Comparison of the DVR and DSI values for the PMI and SMI groups revealed that the DVR and DSI values for the SMI group were lower than those of the PMI group. Also the prognosis of the SMI group tended to be worse than that of the RD (-) group. Thus, we concluded that the SMI and PMI groups should receive identical treatment. (author)

"So oft to the movies they've been": British fan writing and female audiences in the silent cinema

Directory of Open Access Journals (Sweden)

Lisa Rose Stead

2011-03-01

Full Text Available This article aims to address the ways in which working-class and lower-middle-class British women used silent-era fan magazines as a space for articulating their role within the development of a female film culture. The article focuses on letter pages that formed a key site for female contribution to British fan magazines across the silent era. In contributing to these pages, women found a space to debate and discuss the appeal and significance of particular female representations within film culture. Using detailed archival research tracing the content of a specific magazine, Picturegoer, across a 15-year period (1913–28, the article will show the dominance of particular types of female representation in both fan and "official" magazine discourses, analyzing the ways in which British women used these images to work through national tensions regarding modern femininity and traditional ideas of female propriety and restraint.

Myocardial perfusion imaging for detection of silent myocardial ischemia

International Nuclear Information System (INIS)

Beller, G.A.

1988-01-01

Despite the widespread use of the exercise stress test in diagnosing asymptomatic myocardial ischemia, exercise radionuclide imaging remains useful for detecting silent ischemia in numerous patient populations, including those who are totally asymptomatic, those who have chronic stable angina, those who have recovered from an episode of unstable angina or an uncomplicated myocardial infarction, and those who have undergone angioplasty or received thrombolytic therapy. Studies show that thallium scintigraphy is more sensitive than exercise electrocardiography in detecting ischemia, i.e., in part, because perfusion defects occur more frequently than ST depression and before angina in the ischemic cascade. Thallium-201 scintigraphy can be performed to differentiate a true- from a false-positive exercise electrocardiographic test in patients with exercise-induced ST depression and no angina. The development of technetium-labeled isonitriles may improve the accuracy of myocardial perfusion imaging. 11 references

Measuring theory of mind across middle childhood: Reliability and validity of the Silent Films and Strange Stories tasks.

Science.gov (United States)

Devine, Rory T; Hughes, Claire

2016-09-01

Recent years have seen a growth of research on the development of children's ability to reason about others' mental states (or "theory of mind") beyond the narrow confines of the preschool period. The overall aim of this study was to investigate the psychometric properties of a task battery composed of items from Happé's Strange Stories task and Devine and Hughes' Silent Film task. A sample of 460 ethnically and socially diverse children (211 boys) between 7 and 13years of age completed the task battery at two time points separated by 1month. The Strange Stories and Silent Film tasks were strongly correlated even when verbal ability and narrative comprehension were taken into account, and all items loaded onto a single theory-of-mind latent factor. The theory-of-mind latent factor provided reliable estimates of performance across a wide range of theory-of-mind ability and showed no evidence of differential item functioning across gender, ethnicity, or socioeconomic status. The theory-of-mind latent factor also exhibited strong 1-month test-retest reliability, and this stability did not vary as a function of child characteristics. Taken together, these findings provide evidence for the validity and reliability of the Strange Stories and Silent Film task battery as a measure of individual differences in theory of mind suitable for use across middle childhood. We consider the methodological and conceptual implications of these findings for research on theory of mind beyond the preschool years. Copyright © 2015 Elsevier Inc. All rights reserved.

Cross-Border Cholera Outbreaks in Sub-Saharan Africa, the Mystery behind the Silent Illness: What Needs to Be Done?

Godfrey Bwire

Full Text Available Cross-border cholera outbreaks are a major public health problem in Sub-Saharan Africa contributing to the high annual reported cholera cases and deaths. These outbreaks affect all categories of people and are challenging to prevent and control. This article describes lessons learnt during the cross-border cholera outbreak control in Eastern and Southern Africa sub-regions using the case of Uganda-DRC and Malawi-Mozambique borders and makes recommendations for future outbreak prevention and control.We reviewed weekly surveillance data, outbreak response reports and documented experiences on the management of the most recent cross-border cholera outbreaks in Eastern and Southern Africa sub-regions, namely in Uganda and Malawi respectively. Uganda-Democratic Republic of Congo and Malawi-Mozambique borders were selected because the countries sharing these borders reported high cholera disease burden to WHO.A total of 603 cross-border cholera cases with 5 deaths were recorded in Malawi and Uganda in 2015. Uganda recorded 118 cases with 2 deaths and CFR of 1.7%. The under-fives and school going children were the most affected age groups contributing 24.2% and 36.4% of all patients seen along Malawi-Mozambique and Uganda-DRC borders, respectively. These outbreaks lasted for over 3 months and spread to new areas leading to 60 cases with 3 deaths, CRF of 5%, and 102 cases 0 deaths in Malawi and Uganda, respectively. Factors contributing to these outbreaks were: poor sanitation and hygiene, use of contaminated water, floods and rampant cross-border movements. The outbreak control efforts mainly involved unilateral measures implemented by only one of the affected countries.Cross-border cholera outbreaks contribute to the high annual reported cholera burden in Sub-Saharan Africa yet they remain silent, marginalized and poorly identified by cholera actors (governments and international agencies. The under-fives and the school going children were the most

Distribution of Chinese names

We present a statistical model for the distribution of Chinese names. Both family names and given names are studied on the same basis. With naive expectation, the distribution of family names can be very different from that of given names. One is affected mostly by genealogy, while the other can be dominated by cultural effects. However, we find that both distributions can be well described by the same model. Various scaling behaviors can be understood as a result of stochastic processes. The exponents of different power-law distributions are controlled by a single parameter. We also comment on the significance of full-name repetition in Chinese population.

How Silent is the Right to Silence?

Directory of Open Access Journals (Sweden)

Katherine Biber

2012-11-01

Full Text Available A long-held and fundamental principle of our criminal justice system is that people accused of crimes have a right to silence, arising from the presumption of innocence. Rules of evidence try to protect this ‘right’ during trial, by ensuring that juries understand that adverse inferences cannot be drawn from the silence of the accused. Silence, in court, can mean nothing, and we are not to speculate about what might motivate an accused person to remain silent, or what they might have said had they spoken. However, an examination of the jurisprudence in this area shows that the law is often not dealing with actual silence; sometimes when the law refers to the ‘right to silence’, it seems to mean a ‘refusal to hear’. In other instances, there is actual silence, and yet the law refuses to subject that silence to any critical interpretation, insisting that we cannot infer anything from it. While we have learned, from theatre, music, linguistics, religion and psychology, to develop sophisticated means for interpreting silence, the law demands that we set aside these interpretive tools, hearing silence that isn’t there, and inferring nothing about something.

MINORITY LANGUAGE POLICY REGARDING PERSONAL NAMES – AN OVERVIEW

Justyna Walkowiak

2011-01-01

Full Text Available Language Policy (LP with language planning as its implementation is now a well-established field; yet, as evidenced by the scarcity of scholarly literature, seldom concerned with personal names. The paper looks at personal names (given names and surnames and discusses the ways in which they can be perceived as objects of minority LP. Policies regarding personal names are analysed within the framework of the traditional division of language planning into status, corpus and acquisition planning. These policies are then further examined according to other dimensions: what the object of a LP is, who its agent is, what motivates a LP, what effects it exerts, and how a LP is carried out. Finally, the paper looks at EU minority legislation with reference to personal names,especially at the country-specific opinions which reflect the FCNM monitoring process, highlighting areas of controversy. In conclusion, it is shown how vital personal names are to personal and group identity and, consequently, how control over them helps the nation-state control a minority, although – it is argued – not every regulation constitutes a minority LP.

The purpose of this exploratory study was to examine the effects of legal name change on socioeconomic factors, general and transgender-related healthcare access and utilization, and transgender-related victimization in a sample of young transgender women (transwomen) of color. A cross-sectional group comparison approach was used to assess the potential effects of legal name change. A convenience sample of young transwomen enrolled in a no-cost legal name change clinic were recruited to complete a 30-minute interviewer-guided telephone survey including sociodemographic and socioeconomic factors, health and well-being, health care utilization, transgender transition-related health care, and transgender-related victimization. Sixty-five transgender women of color (37 = pre-name change group; 28 = post-name change group) completed the survey. Results indicated that the transwomen in the post-name change group were significantly older than the pre-name change group. In age-adjusted analyses, the post-name change group was significantly more likely to have a higher monthly income and stable housing than the pre-name change group. No significant differences were observed for general healthcare utilization; however, a significantly greater percentage of transwomen in the pre-name change group reported postponing medical care due to their gender identity. In addition, a significantly larger proportion of transwomen in the pre-name change group reported using non-prescribed hormones injected by friends and experiencing verbal harassment by family and friends compared to transwomen in the post-name change group. Findings suggest that legal name change may be an important structural intervention for low-income transwomen of color, providing increased socioeconomic stability and improved access to primary and transition-related health care.

2012-01-01

The role of the meaning of given names has been noted in psychotherapy as well as in everyday life. This study aimed to investigate the possible association between the nature of given names of children and attention deficit hyperactivity disorder (ADHD) diagnosis. A total of 134 given names of children and adolescent patients diagnosed as having ADHD were compared with those of an age- and gender-matched randomly chosen control group from the general population. The first names of the two cohorts were compared with regard to the following: the literal meaning of their names, whether the name constitutes a verb, the prevalence of each name and their length (number of syllables). The meaning of first names of children and adolescents with ADHD combined type were rated by referees as expressing significantly more activity and containing less syllables than the names of controls. In addition, the prevalence of their names was significantly lower than that of names used in the general population. All findings remained significant following Bonferroni adjustment. Our findings demonstrate an intriguing relationship between children's given names and ADHD diagnosis. Given names may serve as a possible predictor of later diagnosis of ADHD. Clinicians should be more attentive to given names in the context of child psychiatric evaluation and therapy. Copyright © 2012 S. Karger AG, Basel.

Correlating lesion size and location to deficits after ischemic stroke: the influence of accounting for altered peri-necrotic tissue and incidental silent infarcts

Directory of Open Access Journals (Sweden)

Black Sandra E

2010-01-01

Full Text Available Abstract Background Investigators frequently quantify and evaluate the location and size of stroke lesions to help uncover cerebral anatomical correlates of deficits observed after first-ever stroke. However, it is common to discover silent infarcts such as lacunes in patients identified clinically as 'first-ever' stroke, and it is unclear if including these incidental findings may impact lesion-based investigations of brain-behaviour relationships. There is also debate concerning how to best define the boundaries of necrotic stroke lesions that blend in an ill-defined way into surrounding tissue, as it is unclear whether including this altered peri-necrotic tissue region may influence studies of brain-behaviour relationships. Therefore, for patients with clinically overt stroke, we examined whether including altered peri-necrotic tissue and incidental silent strokes influenced either lesion volume correlations with a measure of sensorimotor impairment or the anatomical localization of this impairment established using subtraction lesion analysis. Methods Chronic stroke lesions of 41 patients were manually traced from digital T1-MRI to sequentially include the: necrotic lesion core, altered peri-necrotic tissue, silent lesions in the same hemisphere as the index lesion, and silent lesions in the opposite hemisphere. Lesion volumes for each region were examined for correlation with motor impairment scores, and subtraction analysis was used to highlight anatomical lesion loci associated with this deficit. Results For subtraction lesion analysis, including peri-necrotic tissue resulted in a larger region of more frequent damage being seen in the basal ganglia. For correlational analysis, only the volume of the lesion core was significantly associated with motor impairment scores (r = -0.35, p = 0.025. In a sub-analysis of patients with small subcortical index lesions, adding silent lesions in the opposite hemisphere to the volume of the index

Full Text Available Os grupos sociais categoriais são alvo, desde o pós-guerra, de uma intenso esforço de compreensão e demarcação conceitual, principalmente por parte dos psicólogos sociais europeus. A ampliação desta importância na pauta dos pesquisadores se deve ao aumento da presença relativa deste tipo de grupo no cenário das relações sociais e de suas conseqüências na produção das identidades sociais. Neste trabalho indicamos como o crescimento da importância dada aos grupos categoriais acompanha o esvaziamento progressivo do imaginário dos grupos, que passam a operar socialmente menos a partir das relações efetivas entre os indivíduos que os compõem e mais pela sua borda, isto é, o nome do grupo. Chamamos de grupos-nome a esses grupos virtualizados, que não têm presença material mas apenas imagética. Os grupos-nome tendem a ser mais freqüentes do que os grupos "vivos" na medida em que facilitam um relacionamento mais descompromissado entre os indivíduos e portanto mais confortável pela facilidade com a qual os indivíduos poderiam "trocar" de grupo social. Como efeitos da incidência dos grupos-nome destacam-se a transformação dos grupos face a face, a ampliação de mecanismos de controle e manipulação social e o incremento da violência.Categorial social groups have been studied with more interest by the European social psychologists after Second World War.

Care of elderly people is an important socio-economical issue for industrial nations. Stroke is the leading cause of elderly care and its major risk facters are silent brain infarcts and metabolic disorders such as hypertension. Recent progress in brain imaging techniques has enabled early detection of cerebrovascular disease. However, brain imaging of numerous patients is not feasible because the test is time consuming and costly. Furthermore, the epidemiology of silent cerebrovascular disease in hypertensive elderly people is not well-known. Thus, the present study aims to establish whether group brain check-up is effective and to assess the incidence of silent cerebrovascular disease in pre-elderly individuals with hypertension. We randomly enrolled 224 participants, aged 50- to 65-years-old, with hypertension detected during routine medical check-ups. All participants were free of neurological symptoms, or dementia as determined by the Mini Mental Status Examination. MRI was carried out by the simplified method of fast spin echo (FSE)-T2-weighted image (T2WI) and 3D-time of flight (TOF) MRA with Toshiba VISART1.5T, and diagnosed by 3 radiologists. Each imaging test required only 10 minutes and the cost was reduced to about 40-80% number of the usual cost for brain MRIs. The detection rate of abnormal findings was 77.6% (n=174) and that of cerebrovascular changes was 70.1% (n=159; 102 lacunae, 64 intracranial artery stenosis, and 27 cerebral aneurysm), which was much higher than previously reported in a study of random participants. In addition, follow-up questionnaires after the brain check-ups revealed that 86% of participants improved their awareness about health-related life-style. These findings indicate that the pre-elderly population with hypertension is at high-risk for silent cerebrovascular disease, and mass screening of this group using our simplified MRI may be an effective medical health strategy in aging society.

Nomenclature and name assignment rules for the APS storage ring

International Nuclear Information System (INIS)

Decker, G.

1992-01-01

Because the APS accelerators are moving into the fabrication/assembly/installation stage, it is important for consistent naming conventions to be used throughout the project. The intent of this note is to dictate the rules to be adhered to when naming devices in the storage ring. These rules are generic in nature, and shall be applied in principle to the other machines as well. It is essential that every component have a unique and, hopefully, easily recognizable name. Every ASD and XFD group, except for magnets, must interface with the control system. For this reason all device names were developed keeping in mind their actual function, such as controlling or monitoring some device in the ring. Even though magnets are not directly interfaced to the control system, their power supplies are; therefore, a magnet will have the same name as its associated power supply

Importance of 201Tl scintigraphy during exercise for diagnosis of silent myocardial ischemia

International Nuclear Information System (INIS)

Kasalicky, J.; Kidery, J.; Svacinka, J.; Vanko, J.; Brunova, J.; Bartos, V.

1990-01-01

Using thallium scintigraphy during exercise (TSE), suspect silent myocardial ischemia (SIM) was diagnosed in subjects without angina pectoris. 21 active pilots with suspect SIM were examined after previous exercise ECG as well as 33 patients with diabetes type I and II. In six pilots (28.6%) TSE showed accumulation defects suggesting ischemic disorders of the large coronary arteries. Five pilots showed obvious depressions of the ST segment in ECG during submaximal exercise TSE. In another group of five pilots small depressions of the ST segment were associated with normal TSE. Twelve diabetic patients (36.4%) had minor accumulation defects on TSE. Only two showed a ST depression under 2 mm in ECG during TSE. Based on data in the literature suggesting higher sensitivity and specificity of exercise thallium scintigraphy as compared with exercise ECG and the possibility of a false positive diagnosis of SIM from exercise ECG alone, it is recommended to also use TSE. A more detailed diagnosis of SIM is essential not only with regard to the assessment of work capacity but also for a long-term follow-up of patients with SIM for assessment of its incidence, impact and prognosis in the population.

Three paternity tests cases were found with a single locus mismatch at the locus D5S818 with PowerPlex®21 PCR Amplification Kit (Promega). Forward and reverse primers were redesigned to type the samples again and to evaluate if there were alleles dropped out. The results showed the existence of a silent allele 12 in all the three families, due to a point mutation that changed cytosine to adenine at 90 nucleotides upstream from the 5' end of the AGAT repeat sequences in all the six individuals. A single locus mismatch due to a silent allele may occur in any locus using any kit. Therefore, we recommend using multiple kits to confirm the results in paternity testing cases with mismatches, especially when there is a single locus mismatch with homozygote involved.

2012-01-01

Objective: To compare 99 Tc m -tetrofosmin (TF) and 99 Tc m -MIBI adenosine stress/resting MPI in detection of silent myocardial ischemia (SMI). Methods: According to the WHO diagnostic criteria for coronary heart disease (CHD), 306 SMI patients were classified to three groups as type Ⅰ (n=122), type Ⅱ (n=112) and type Ⅲ (n=72). The subjects of each type were randomly divided into 2 subgroups; one subgroup underwent adenosine stress/rest MPI with 99 Tc m -MIBI and another subgroup with 99 Tc m -TF. The clinical diagnosis of CHD was proven with electrocardiogram (46 cases), dynamic electrocardiogram (219 cases) or CAG (41 cases). Comparison factors between the two tracers included image quality and diagnostic efficacy. The image quality was graded into three classes:excellent, good and moderate. χ 2 test and analysis of variance were used to analyze data. Results: The sensitivities of detecting myocardial ischemia with 99 Tc m -MIBI MPI and 99 Tc m -TF MPI in group type Ⅰ were 57.38% (35/61) vs 60.66% (37/61) (χ 2 =0.136, P>0.05); in group type Ⅱ 69.64% (39/56) vs 64.29% (36/56) (χ 2 =0.363, P>0.05) and in group type Ⅲ 83.33% (30/36) vs 88.89% (32/36) (χ 2 =0.465, P>0.05), respectively. There was no significant difference between the sensitivities of the two imaging modalities in all three types of SMI patients.In image quality grading, 99 Tc m -MIBI and 99 Tc m -TF demonstrated excellent images with 41.18% (63/153) vs 48.37% (74/153) (χ 2 =1.599, P=0.206), good with 45.10% (69/153) vs 34.64% (53/153) (χ 2 =3.489, P=0.062) and moderate with 13.72% (21/153) vs 16.99%(26/153) (χ 2 =0.628, P=0.428). There was no unqualified image with either modality. 99 Tc m -TF displayed quicker radioactivity clearance in liver and lungs. Thereby there was less interference or pitfalls present in the ventricle base or interior wall that may result from higher liver radioactivity retention. The waiting time between the tracer injection and imaging was at least 1 h

Directory of awardee names

Energy Technology Data Exchange (ETDEWEB)

1999-07-01

Standardization of grant and contract awardee names has been an area of concern since the development of the Department`s Procurement and Assistance Data System (PADS). A joint effort was begun in 1983 by the Office of Scientific and Technical Information (OSTI) and the Office of Procurement and Assistance Management/Information Systems and Analysis Division to develop a means for providing uniformity of awardee names. As a result of this effort, a method of assigning vendor identification codes to each unique awardee name, division, city, and state combination was developed and is maintained by OSTI. Changes to vendor identification codes or awardee names contained in PADS can be made only by OSTI. Awardee names in the Directory indicate that the awardee has had a prime contract (excluding purchase orders of $10,000 or less) with, or a financial assistance award from, the Department. Award status--active, inactive, or retired--is not shown. The Directory is in alphabetic sequence based on awardee name and reflects the OSTI-assigned vendor identification code to the right of the name. A vendor identification code is assigned to each unique awardee name, division, city, and state (for place of performance). The same vendor identification code is used for awards throughout the Department.

In this study, the first and last names of people (FN and LN), enterprises (EN) (with plants'species roots in their names) and phytotoponyms (PT) in five Croatian regions are analyzed, in their relationships. The goals of the study were: to determine the correlations between FN, LN, EN and PT; to determine the latent structure of these variables; to forecast number of PT (criterion) on the base of predictors (FN, LN, EN); to determine grouping of the places (within certain regions) as cases by two plants' categorizations; to determine grouping of the plants as cases by regions. We have analyzed 15 places, grouped in five regions, with 39 different plant species. The results revealed that the only principal component highly positively correlated with the variables last name and office name, while the projections for the variables first name (moderate high) and phytotoponyms (low size) were negative. Prediction of the criteria phytotoponyms is satisfactorily good, using three predictors: last name, first name and the office name. First cluster analysis revealed that phytotoponyms are mostly related with trees and deciduous plants, while names are related with trees, deciduous and herbaceous plants. Second cluster analysis obtained clear distinction between regions in dominant PTs, based on certain plants' names. The results indicate clear association between phytotoponyms and names of people.

By which name should I call thee? The consequences of having multiple names.

Science.gov (United States)

Stevenage, Sarah V; Lewis, Hugh G

The nominal competitor effect suggests that, when a person has two names associated with them, recall of either name is more difficult than if they just had one name. Drawing on a connectionist framework, this effect could arise either if multiple names were represented as being connected to a single person identity node (PIN), or if multiple names were represented as being connected via one-to-one links to multiple PINs. Whilst the latter has intuitive appeal, results from two experiments support the former architecture. Having two names connected to a single PIN not only gives rise to a nominal competitor effect (Experiment 1), but also gives rise to a familiarity enhancement effect (Experiment 2). These empirical results are simulated using an extension of Brédart, Valentine, Calder, and Gassi's (1995) connectionist architecture, which reveals that both effects hold even when the association of both names to the PIN is unequal. These results are presented in terms of a more complete model for person recognition, and the representation of semantic information within such a model is examined.

Ziziphus jujuba stimulates the release of nitric oxide (NO). Because NO is involved in cardiovascular regulations, in this study the effects of hydroalcoholic extract of Z. jujuba on cardiovascular responses in acute NG-nitro-L-arginine methyl ester (L-NAME) hypertensive rats were evaluated. Rats were divided into 6 group (n=6): 1) saline, 2) L-NAME received (10mg/kg) intravenously, 3) sodium nitroprusside (SNP) (50µg/kg)+L-NAME group received SNP before L-NAME and 4-6) three groups of Z. jujuba (100, 200 and 400mg/kg) that treated for four weeks and on the 28 th day, L-NAME was injected. Femoral artery and vein were cannulated for recording cardiovascular responses and drug injection, respectively. Systolic blood pressure (SBP), Mean arterial pressure (MAP) and heart rate (HR) were recorded continuously. Maximal changes (∆) of SBP, MAP and HR were calculated and compared to control and L-NAME groups. In L-NAME group, maximal ΔSBP (L-NAME: 44.15±4.0 mmHg vs control: 0.71±2.1 mmHg) and ΔMAP (L-NAME: 40.8±4.0 mmHg vs control: 0.57±1.6 mmHg) significantly increased (p0.05). All doses of Z. jujuba attenuated maximal ∆SBP and ∆MAP induced by L-NAME but only the lowest dose (100 mg/kg) had significant effects (ΔSBP: 20.36±5.6 mmHg vs L-NAME: 44.1±4.0 mmHg and ΔMAP: 20.8±4.5 mmHg vs L-NAME: 40.8±3.8 mmHg (pL-NAME group (p>0.05). Because long-term consumption of Z. jujuba extract, especially its lowest dose, attenuated cardiovascular responses induced by L-NAME, we suggest that Z. jujuba has potential beneficial effects in prevention of hypertension induced by NO deficiency.

Two hundred and seven Japanese elementary school children aged from 6 (Grade 1) to 12 (Grade 6) years old were tested for their abilities to name numbers and pictured objects along with reading Hiragana characters and words. These children all showed typical development and their classroom teachers judged that they were not having any problems with reading or writing. The children were randomly divided into two groups, the first group was assigned to two naming tasks;the rapid automatized naming (RAN) of "numbers" and "pictured objects," the second group was assigned to two rapid alternative stimulus (RAS) naming tasks using numbers and pictured objects. All children were asked to perform two reading tasks that were written in Hiragana script: single mora reading task and four syllable word reading task. The total articulation time for naming and reading and performance in terms of accuracy were measured for each task. Developmental changes in these variables were evaluated. The articulation time was significantly longer for the first graders, and it gradually shortened as they moved through to the upper grades in all tasks. The articulation time reached a plateau in the 5th grade for the number naming, while gradual change continued after drastic change in the lower grades for the pictured object naming. The articulation times for the single mora reading and RAN of numbers correlated strongly. The articulation time for the RAS naming was significantly longer compared to that for the RAN, though there were very few errors. The RAS naming showed the highest correlation with the four syllable word reading. This study demonstrated that the performance in rapid automatized naming of numbers and pictures were closely related with performance on reading tasks. Thus Japanese children with reading disorders such as developmental dyslexia should also be evaluated for rapid automatized naming.

Accruing evidence suggests that the cognitive deficits in very early Alzheimer's Disease (AD) are not confined to episodic memory, with a number of studies documenting semantic memory deficits, especially for knowledge of people. To investigate whether this difficulty in naming famous people extends to other proper names based information, three naming tasks - the Graded Naming Test (GNT), which uses objects and animals, the Graded Faces Test (GFT) and the newly designed Graded Buildings Test (GBT) - were administered to 69 participants (32 patients in the early prodromal stage of AD, so-called Mild Cognitive Impairment (MCI), and 37 normal control participants). Patients were found to be impaired on all three tests compared to controls, although naming of objects was significantly better than naming of faces and buildings. Discriminant analysis successfully predicted group membership for 100% controls and 78.1% of patients. The results suggest that even in cases that do not yet fulfil criteria for AD naming of famous people and buildings is impaired, and that both these semantic domains show greater vulnerability than general semantic knowledge. A semantic deficit together with the hallmark episodic deficit may be common in MCI, and that the use of graded tasks tapping semantic memory may be useful for the early identification of patients with MCI.

Full Text Available Introduction and Aim: Tuberculosis (TB poses a severe risk to public health through the world but excessively distresses low-income nations. The aim of this study is to analyze silent changes of TB in Iran (2005–2015: A joinpoint regression analysis. Materials and Methods: This is a trend study conducted on all patients (n = 70 that register in control disease center of Joibar (one of coastal cities and tourism destination in Northern Iran which was recognized as an independent town since 1998 during 2005–2015. The characteristics of patients imported to the SPSS 19 and variation in incidence rate of different forms of pulmonary TB (PTB (PTB+ or PTB– and extra-PTB (EPTB/year was analyzed. Variation in incidence rate of TB for male and female groups and different age groups (0–14, 15–24, 25–34, 35–44, 45–54, 55–64, and above 65 years was analyzed, variation in trend of this diseases for different groups was compared in intended years, and also, variation in incidence rate of TB was analyzed by Joinpoint Regression Software. Results: The total number of TB was 70 cases during 2005–2015. The mean age of patients was 42.31 ± 21.26 years and median age was 40 years. About 71.4% of patients were PTB (55.7% for with PTB+ and 15.7% with PTB– and rest of them (28.4% were EPTB. In regard to classification of cases, 97.1% of them were new cases, 1.45% of them were relapsed cases, and 1.45% of them imported cases. In addition, history of hospitalization due to TB was observed in 44.3%. Conclusion: Despite recent developments of governmental health-care system in Iran and proper access to it and considering this fact that identification of TB cases with passive surveillance is possible. Hence, developing certain programs for sensitization of the covered population is essential.

What's in a Name? Sound Symbolism and Gender in First Names.

Directory of Open Access Journals (Sweden)

David M Sidhu

Full Text Available Although the arbitrariness of language has been considered one of its defining features, studies have demonstrated that certain phonemes tend to be associated with certain kinds of meaning. A well-known example is the Bouba/Kiki effect, in which nonwords like bouba are associated with round shapes while nonwords like kiki are associated with sharp shapes. These sound symbolic associations have thus far been limited to nonwords. Here we tested whether or not the Bouba/Kiki effect extends to existing lexical stimuli; in particular, real first names. We found that the roundness/sharpness of the phonemes in first names impacted whether the names were associated with round or sharp shapes in the form of character silhouettes (Experiments 1a and 1b. We also observed an association between femaleness and round shapes, and maleness and sharp shapes. We next investigated whether this association would extend to the features of language and found the proportion of round-sounding phonemes was related to name gender (Analysis of Category Norms. Finally, we investigated whether sound symbolic associations for first names would be observed for other abstract properties; in particular, personality traits (Experiment 2. We found that adjectives previously judged to be either descriptive of a figuratively 'round' or a 'sharp' personality were associated with names containing either round- or sharp-sounding phonemes, respectively. These results demonstrate that sound symbolic associations extend to existing lexical stimuli, providing a new example of non-arbitrary mappings between form and meaning.

An Assessment of the Need for Standard Variable Names for Airborne Field Campaigns

2017-12-01

The NASA Earth Venture Program has led to a dramatic increase in airborne observations, requiring updated data management practices with clearly defined data standards and protocols for metadata. An airborne field campaign can involve multiple aircraft and a variety of instruments. It is quite common to have different instruments/techniques measure the same parameter on one or more aircraft platforms. This creates a need to allow instrument Principal Investigators (PIs) to name their variables in a way that would distinguish them across various data sets. A lack of standardization of variables names presents a challenge for data search tools in enabling discovery of similar data across airborne studies, aircraft platforms, and instruments. This was also identified by data users as one of the top issues in data use. One effective approach for mitigating this problem is to enforce variable name standardization, which can effectively map the unique PI variable names to fixed standard names. In order to ensure consistency amongst the standard names, it will be necessary to choose them from a controlled list. However, no such list currently exists despite a number of previous efforts to establish a sufficient list of atmospheric variable names. The Atmospheric Composition Variable Standard Name Working Group was established under the auspices of NASA's Earth Science Data Systems Working Group (ESDSWG) to solicit research community feedback to create a list of standard names that are acceptable to data providers and data users This presentation will discuss the challenges and recommendations of standard variable names in an effort to demonstrate how airborne metadata curation/management can be improved to streamline data ingest, improve interoperability, and discoverability to a broader user community.

Using magnetic resonance imaging, we aimed to assess the presence of silent brain vascular lesions in a sample of apparently healthy elderly individuals who were recruited from an economically disadvantaged urban region (São Paulo, Brazil). We also wished to investigate whether the findings were associated with worse cognitive performance. A sample of 250 elderly subjects (66-75 years) without dementia or neuropsychiatric disorders were recruited from predefined census sectors of an economically disadvantaged area of Sao Paulo and received structural magnetic resonance imaging scans and cognitive testing. A high proportion of individuals had very low levels of education (4 years or less, n=185; 21 with no formal education). The prevalence of at least one silent vascular-related cortical or subcortical lesion was 22.8% (95% confidence interval, 17.7-28.5), and the basal ganglia was the most frequently affected site (63.14% of cases). The subgroup with brain infarcts presented significantly lower levels of education than the subgroup with no brain lesions as well as significantly worse current performance in cognitive test domains, including memory and attention (pcognitive deficits, and in the absence of magnetic resonance imaging data, this cognitive impairment may be considered simply related to ageing. Emphatic attention should be paid to potentially deleterious effects of vascular brain lesions in poorly educated elderly individuals from economically disadvantaged environments.

Reducing calorie sales from supermarkets - 'silent' reformulation of retailer-brand food products.

Food product reformulation is seen as one among several tools to promote healthier eating. Reformulating the recipe for a processed food, e.g. reducing the fat, sugar or salt content of the foods, or increasing the content of whole-grains, can help the consumers to pursue a healthier life style. In this study, we evaluate the effects on calorie sales of a 'silent' reformulation strategy, where a retail chain's private-label brands are reformulated to a lower energy density without making specific claims on the product. Using an ecological study design, we analyse 52 weeks' sales data - enriched with data on products' energy density - from a Danish retail chain. Sales of eight product categories were studied. Within each of these categories, specific products had been reformulated during the 52 weeks data period. Using econometric methods, we decompose the changes in calorie turnover and sales value into direct and indirect effects of product reformulation. For all considered products, the direct effect of product reformulation was a reduction in the sale of calories from the respective product categories - between 0.5 and 8.2%. In several cases, the reformulation led to indirect substitution effects that were counterproductive with regard to reducing calorie turnover. However, except in two insignificant cases, these indirect substitution effects were dominated by the direct effect of the reformulation, leading to net reductions in calorie sales between -3.1 and 7.5%. For all considered product reformulations, the reformulation had either positive, zero or very moderate negative effects on the sales value of the product category to which the reformulated product belonged. Based on these findings, 'silent' reformulation of retailer's private brands towards lower energy density seems to contribute to lowering the calorie intake in the population (although to a moderate extent) with moderate losses in retailer's sales revenues.

Multi-language naming game

Naming game is a simulation-based experiment used to study the evolution of languages. The conventional naming game focuses on a single language. In this paper, a novel naming game model named multi-language naming game (MLNG) is proposed, where the agents are different-language speakers who cannot communicate with each other without a translator (interpreter) in between. The MLNG model is general, capable of managing k different languages with k ≥ 2. For illustration, the paper only discusses the MLNG with two different languages, and studies five representative network topologies, namely random-graph, WS small-world, NW small-world, scale-free, and random-triangle topologies. Simulation and analysis results both show that: 1) using the network features and based on the proportion of translators the probability of establishing a conversation between two or three agents can be theoretically estimated; 2) the relationship between the convergence speed and the proportion of translators has a power-law-like relation; 3) different agents require different memory sizes, thus a local memory allocation rule is recommended for saving memory resources. The new model and new findings should be useful for further studies of naming games and for better understanding of languages evolution from a dynamical network perspective.

Silent myocardial ischaemia - as evaluated by stress-induced perfusion defects on myocardial perfusion scintigraphy (MPS) in patients without a history of chest pain - is frequent in diabetes and is associated with increased rates of cardiovascular events. Its prevalence has been determined in asymptomatic diabetic patients, but remains largely unknown in diabetic patients with suspected coronary artery disease (CAD) in the clinical setting. In this study we therefore sought (a) to determine the prevalence of symptomatic and silent perfusion defects in diabetic patients with suspected CAD and (b) to characterise the eventual predictors of abnormal perfusion. The patient population comprised 133 consecutive diabetic patients with suspected CAD who had been referred for MPS. Studies were performed with exercise (41%) or pharmacological stress testing (1-day protocol, {sup 99m}Tc-sestamibi, {sup 201}Tl or both). We used semi-quantitative analysis (20-segment polar maps) to derive the summed stress score (SSS) and the summed difference score (SDS). Abnormal MPS (SSS{>=}4) was observed in 49 (37%) patients (SSS=4.9{+-}8.4, SDS=2.4{+-}4.7), reversible perfusion defects (SDS{>=}2) in 40 (30%) patients [SSS=13.3{+-}10.9; SDS=8.0{+-}5.6; 20% moderate to severe (SDS>4), 7% multivessel] and fixed defects in 21 (16%) patients. Results were comparable between patients with and patients without a history of chest pain. Of 75 patients without a history of chest pain, 23 (31%, 95% CI=21-42%) presented reversible defects (SSS=13.9{+-}11.3; SDS=7.4{+-}1.2), indicative of silent ischaemia. Reversible defects were associated with inducible ST segment depression during MPS stress (odds ratio (OR)=3.2, p<0.01). Fixed defects were associated with erectile dysfunction in males (OR=3.7, p=0.02) and lower aspirin use (OR=0.25, p=0.02). Silent stress-induced perfusion defects occurred in 31% of the patients, a rate similar to that in patients with a history of chest pain. MPS could identify

Full Text Available Objective: to assess the rate of silent myocardial ischemia (SMI and the pattern of cardiac rhythm disturbances in women with rheumatoidarthritis (RA, their association with traditional risk factors (TRF for cardiovascular diseases (CVD, with subclinical structural and functionalchanges in the heart and vessels, with the activity and severity of rheumatoid inflammation.Subjects and methods. Two hundred and ninety-one female patients aged less than 60 years with a valid diagnosis of RA and no clinicalsigns were examined. A control group consisted of 125 women without rheumatic diseases. In addition to the clinical manifestations, activity,and severity of RA, the authors assessed major TRFs for CVD, performed Holter ECG monitoring, common carotid artery duplex scanning, transthoracic echocardiographic study, and determined the levels of serum inflammatory markers.Results. The women with RA differ from the control group in the higher incidence of SMI, supraventricular arrhythmias (SVA and highgradepremature ventricular contractions (PVC. The patients with RA and SMI are characterized in terms of age-adjustment by higher disease activity (DAS28, systemic manifestations, cumulative larger-dose glucocorticoids (GC and a higher percentage of patients receiving disease-modifying anti-rheumatic drugs as compared with those with RA and no SMI with adjustment for age. High disease activity(DAS28, level of inflammatory markers, IgM rheumatoid arthritis seropositivity, and GC therapy are SVA-associated factors in women with RA; larger left ventricular end-diastolic dimension and serositis are factors associated with high-grade PVC.Conclusion. The RA women without clinical manifestations of CVD are recorded to have high rates of SMI, SVA, and high-grade PVC, which is primarily due to the activity and severity of rheumatoid inflammation.

Full Text Available Background. Insulin resistance (IR is part of the metabolic syndrome (Mets that develops after lifestyle changes and obesity. Although the association between Mets and myocardial injury is well known, the effect of IR on myocardial damage remains unclear. Methods and Results. We studied 2200 normal subjects who participated in a community-based health check in the town of Takahata in northern Japan. The presence of IR was assessed by homeostasis model assessment ratio, and the serum level of heart-type fatty acid binding protein (H-FABP was measured as a maker of silent and ongoing myocardial damage. H-FABP levels were significantly higher in subjects with IR and Mets than in those without metabolic disorder regardless of gender. Multivariate logistic analysis showed that the presence of IR was independently associated with latent myocardial damage (odds ratio: 1.574, 95% confidence interval 1.1–2.3 similar to the presence of Mets. Conclusions. In a screening of healthy subjects, IR and Mets were similarly related to higher H-FABP levels, suggesting that there may be an asymptomatic population in the early stages of metabolic disorder that is exposed to myocardial damage and might be susceptible to silent heart failure.

Ethnicity and Population Structure in Personal Naming Networks

Mateos, Pablo; Longley, Paul A.; O'Sullivan, David

2011-01-01

Personal naming practices exist in all human groups and are far from random. Rather, they continue to reflect social norms and ethno-cultural customs that have developed over generations. As a consequence, contemporary name frequency distributions retain distinct geographic, social and ethno-cultural patterning that can be exploited to understand population structure in human biology, public health and social science. Previous attempts to detect and delineate such structure in large populations have entailed extensive empirical analysis of naming conventions in different parts of the world without seeking any general or automated methods of population classification by ethno-cultural origin. Here we show how ‘naming networks’, constructed from forename-surname pairs of a large sample of the contemporary human population in 17 countries, provide a valuable representation of cultural, ethnic and linguistic population structure around the world. This innovative approach enriches and adds value to automated population classification through conventional national data sources such as telephone directories and electoral registers. The method identifies clear social and ethno-cultural clusters in such naming networks that extend far beyond the geographic areas in which particular names originated, and that are preserved even after international migration. Moreover, one of the most striking findings of this approach is that these clusters simply ‘emerge’ from the aggregation of millions of individual decisions on parental naming practices for their children, without any prior knowledge introduced by the researcher. Our probabilistic approach to community assignment, both at city level as well as at a global scale, helps to reveal the degree of isolation, integration or overlap between human populations in our rapidly globalising world. As such, this work has important implications for research in population genetics, public health, and social science adding new

The purpose of this study was to estimate the cost-effectiveness of two screening methods for detection of silent AF, intermittent electrocardiogram (ECG) recordings using a handheld recording device, at regular time intervals for 30 days, and short-term 24 h continuous Holter ECG, in comparison with a no-screening alternative in 75-year-old patients with a recent ischaemic stroke. The long-term (20-year) costs and effects of all alternatives were estimated with a decision analytic model combining the result of a clinical study and epidemiological data from Sweden. The structure of a cost-effectiveness analysis was used in this study. The short-term decision tree model analysed the screening procedure until the onset of anticoagulant treatment. The second part of the decision model followed a Markov design, simulating the patients' health states for 20 years. Continuous 24 h ECG recording was inferior to intermittent ECG in terms of cost-effectiveness, due to both lower sensitivity and higher costs. The base-case analysis compared intermittent ECG screening with no screening of patients with recent stroke. The implementation of the screening programme on 1000 patients resulted over a 20-year period in 11 avoided strokes and the gain of 29 life-years, or 23 quality-adjusted life years, and cost savings of €55 400. Screening of silent AF by intermittent ECG recordings in patients with a recent ischaemic stroke is a cost-effective use of health care resources saving costs and lives and improving the quality of life.

In this paper, we examine the evolution of functional groups (carbonyl, carboxyl, phenol, and hydroxyl) during stabilization at 100–200 °C of two typical wood derived pyrolysis oils from BTG and Amaron in a batch reactor over Ru/C catalyst for 4h. An aqueous and an oily phase were obtained. The content of functional groups in both phases were analyzed by GC/MS, 31P-NMR, 1H-NMR, elemental analysis, KF titration, carbonyl groups by Faix, Folin – Ciocalteu method and UV-Fluorescence. The consumption of hydrogen was between 0.007 and 0.016 g/g oil, and 0.001-0.020 g of CH4/g of oil, 0.005-0.016 g of CO2/g oil and 0.03-0.10 g H2O/g oil were formed. The content of carbonyl, hydroxyl, and carboxyl groups in the volatile GC-MS detectable fraction decreased (80, 65, and ~70% respectively), while their behavior in the total oil and hence in the non-volatile fraction was more complex. The carbonyl groups initially decreased having minimum at ~125-150°C and then increased, while the hydroxyl groups had reversed trend. This might be explained by initial hydrogenation of the carbonyl groups to form hydroxyls, followed by continued dehydration reactions at higher temperatures that may increase their content. The 31P-NMR was on the limit of its sensitivity for the carboxylic groups to precisely detect changes in the non-volatile fraction, however the more precise titration method showed that the concentration of carboxylic groups in the non-volatile fraction remains constant with increased stabilization temperature. The UV-Fluorescence results show that repolymerization increases with temperature. ATR-FTIR method coupled with deconvolution of the region between 1490 and 1850 cm-1 showed to be a good tool for following the changes in carbonyl groups and phenols of the stabilized pyrolysis oils. The deconvolution of the IR bands around 1050 and 1260 cm-1 correlated very well with the changes in the 31P-NMR silent O groups (likely ethers). Most of the H2O formation could be

Full Text Available The research aims to account for the Marked Balinese Students’ Personal Names. Four research problems are studied, namely (1 the criteria used to distinguish the marked names (NDMBmk and the unmarked ones (NDMTBmk, (2 the functions of the markedness, (3 the factors that influence it, and (4 the ideologies that operate behind it. The markedness of personal names reflect a relation between the arbitrariness in language uses and the extralinguistic factors influencing it. In the context of Balinese, the tradition, legal practices, and the globalisation may affect the arbitrariness. In order to determine NDMBmk, criteria of markedness was constructed. According to the criteria, structurally, NDMBmk consist of at least five elements, as Anak Agung Arim Kasunu Arya Penarungan. Behaviorally, they may consist of names not derived from Balinese and/or Sanskrit, such as Giovani on I Gede Adeyaka Giovani, adopt a foreign spelling system as Chrisna on Ni Putu Chrisna Wulandari, or use no markers of Balinese ethnics or caste as Yunisari Wira Putri. Out of 698 sampled names, NDMBmk are found 54. Besides denoting, the marked elements also function to distinguish personal identities, to shape the existence of the name holder, to connote particular perception, and to reflect the changing era. The factors influencing the markedness are the need to express something new, a wish to acculturate, to raise status or keep a distance socially, and to demonstrate a linguistic expertise, or when seeing from the concept of imagery, the factors are the imagery on something new and on social status or distancing. The ideologies behind the phenomenon are globalist, nationalist, and the casteless-Balinese.

On identifying name equivalences in digital libraries. Name equivalence, Surname matching, Author identification, Databases

Directory of Open Access Journals (Sweden)

2004-01-01

Full Text Available The services provided by digital libraries can be much improved by correctly identifying variants of the same name. For example, this will allow for better retrieval of all the works by a certain author. We focus on variants caused by abbreviations of first names, and show that significant achievements are possible by simple lexical analysis and comparison of names. This is done in two steps: first a pairwise matching of names is performed, and then these are used to find cliques of equivalent names. However, these steps can each be performed in a variety of ways. We therefore conduct an experimental analysis using two real datasets to find which approaches actually work well in practice. Interestingly, this depends on the size of the repository, as larger repositories may have many more similar names.

Temporal Features of the Differentiation between Self-Name and Religious Leader Name among Christians: An ERP Study

Ruixue Xia

2018-01-01

Full Text Available Existing neuroimaging studies have shown that religion, as a subjective culture, can influence self-referential processing. However, the time course of this impact remains unclear. The present study examined how Christians process their own names, the name of their religious leader (i.e., Jesus, and a famous person’s name (i.e., Yao Ming. Behavioral and EEG data were recorded while the participants performed a name-color judgment task for these three names. The behavioral data showed no significant differences in reaction time or accuracy among the names. However, the ERP data showed that the P200 and P300 amplitudes elicited by the self-name and religious leader name were larger than those elicited by the famous name. Furthermore, the self-name also elicited a larger P300 amplitude than the religious leader name did. These results suggested that both the self-name and the religious leader name were processed preferentially due to their important social value for the self as compared to a generally famous name. Importantly, the dissociation between the self-name and the religious leader name was observed at a high-order cognitive stage, which might be attributed to their different roles in one’s self-concept.

Naming names: the first women taxonomists in mycology

Full Text Available The transition from amateur to professional in natural history is generally regarded as having taken place in the nineteenth century, but landmark events such as the 1917 appointment of mycologist Johanna Westerdijk (1883–1961 as the first female professor in the Netherlands indicate that the pattern of change for women was more varied and delayed than for men. We investigate this transition in mycology, and identify only 43 women in the Western World who published scientific mycological literature pre-1900, of whom twelve published new fungal taxa. By charting the emergence of these women over time, and comparing the output of self-taught amateurs and university graduates, we establish the key role of access to higher education in female participation in mycology. Using a suite of strategies, six of the self-taught amateurs managed to overcome their educational disadvantages and name names — Catharina Dörrien (the first to name a fungal taxon, Marie-Anne Libert, Mary Elizabeth Banning, Élise-Caroline Bommer, Mariette Rousseau, and Annie Lorrain Smith. By 1900, the professional era for women in mycology was underway, and increasing numbers published new taxa. Parity with male colleagues in recognition and promotion, however, remains an ongoing issue. Key words: Amateurs, Fungi, Gender studies, History of science, Plant pathology

Gunshot tracheal injuries represent life-threatening events and usually necessitate emergent surgical intervention. We report a case of an exceptional finding of a patient with retained ballistic fragments in the soft tissues of the thorax, proximal to the right subclavian artery and the trachea, carrying silently his wounds for two decades without any medical or surgical intervention. The bullet pellet on the upper part of the trachea seen accidentally in the chest computed tomography, was also found during bronchoscopy. In short "luck's always to blame".

GEOGRAPHIC NAMES INFORMATION SYSTEM (GNIS) ...

Science.gov (United States)

The Geographic Names Information System (GNIS), developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names (BGN), contains information about physical and cultural geographic features in the United States and associated areas, both current and historical, but not including roads and highways. The database also contains geographic names in Antarctica. The database holds the Federally recognized name of each feature and defines the location of the feature by state, county, USGS topographic map, and geographic coordinates. Other feature attributes include names or spellings other than the official name, feature designations, feature class, historical and descriptive information, and for some categories of features the geometric boundaries. The database assigns a unique feature identifier, a random number, that is a key for accessing, integrating, or reconciling GNIS data with other data sets. The GNIS is our Nation's official repository of domestic geographic feature names information.

In this study, peripheral blood lymphocytes were compared between a brand-name and a generic tacrolimus group in stable liver transplant recipients. Sixteen patients who underwent ABO-compatible living donor liver transplants between 2012 and 2013 and had stable graft function were included in this study. Ten patients received brand-name tacrolimus and 6 patients received generic tacrolimus. CD3, CD4, CD8, γδ, CD4+FoxP3+, and CD3-CD56+ T cells were analyzed in peripheral blood obtained preoperatively and 4, 8, 12, and 24 weeks after liver transplantation. Categorical variables were compared using a χ2 test or Fisher exact test, and continuous variables were compared using the Mann-Whitney U test. Regarding the baseline and perioperative characteristics, there were no statistically significant differences between the 2 groups. Immunosuppression also was not different. Subtype analysis of T-cell populations carried out in parallel showed similar levels of CD3, CD4, CD8, and γδT cells with brand-name tacrolimus and generic tacrolimus in stable liver transplant recipients. However, the levels of CD4+Foxp3+ and CD3-CD56+ T cells were higher in the brand-name tacrolimus group than in the generic tacrolimus group 8 weeks after transplantation (p brand-name tacrolimus group than in the generic tacrolimus group after transplantation. This finding showed that brand-name tacrolimus could have more potential immunosuppressive activity than generic tacrolimus regarding the contribution of CD4+Foxp3+ T cells to graft tolerance in liver transplant recipients. © 2017 S.

Coherent states associated to the Jacobi group

International Nuclear Information System (INIS)

Berceanu, S.

2007-01-01

.The coherent states (CS) offer a useful connection between classical and quantum mechanics. In several previous works we have constructed CS attached to the Jacobi group. It is well known that the Jacobi group appears in Quantum Mechanics, Geometric Quantization, Optics. The mathematicians have given the name 'Jacobi group' to the semidirect product of the Heisenberg-Weyl group and the symplectic group. The same group is known to physicists under other names, as the Schroedinger group. Also the name 'Weyl-symplectic' group is used for the same semi-direct product of the Heisenberg-Weyl group and the symplectic group. In this paper we review and discuss some properties of the coherent states associated to the Jacobi group. (author)

Silent Aortic Dissection Presenting as Transient Locked-In Syndrome

Nadour, Wadih; Goldwasser, Brian; Biederman, Robert W.; Taffe, Kevin

2008-01-01

Acute aortic dissection is a medical emergency. Without prompt recognition and treatment, the mortality rate is high. An atypical presentation makes timely diagnosis difficult, especially if the patient is experiencing no characteristic pain. Many patients with aortic dissection are reported to have presented with various neurologic manifestations, but none with only a presentation of transient locked-in syndrome. Herein, we report a case of completely painless aortic dissection in a woman who presented with a transient episode of anarthria, quadriplegia, and preserved consciousness. On physical examination, she had a 40-point difference in blood pressure between her left and right arms, and a loud diastolic murmur. The diagnosis of acute aortic dissection was reached via a combination of radiography, computed tomography, echocardiography, and a high index of clinical suspicion. The patient underwent emergency surgery and ultimately experienced a successful outcome. To our knowledge, this is the 1st report of aortic dissection that presented solely as locked-in syndrome. We suggest that silent aortic dissection be added to the differential diagnosis for transient locked-in syndrome. PMID:18941610

On streamlining the Ukrainian names of plants. Information 7. Spelling the names of plant varieties.

Directory of Open Access Journals (Sweden)

В. М. Меженський

2016-07-01

Full Text Available Purpose. To analyse the practice of transliteration of the Ukrainian cultivar names and rendering foreign names by means of the Ukrainian language, as well as special aspects of cultivar names spelling in special literature. Results. Cultivar names as a special category require preservation of primary graphics or sound type in the other language. This can be achieved by direct inclusion of the original name to the Ukrainian text or by practical transcribing, but not by transliteration or translation. Otherwise, Ukrainian names should be transliterated for inclusion to the texts in Latin characters. Transcription/transliteration in both directions is performed from the source language, though, as practice shows, in some Ukrainian publications the Russian is wrongly used as an intermediary language. Some national scientific publications ignore the recommendations of the International Code of Nomenclature for Cultivated Plants that is not conducive to the success of scientific communication in the globalized world. Conclusions. The foreign names of plant varieties should be entered into the Ukrainian text keeping the original spelling or by means of practical transcription. The loan of foreign names is performed by transcribing directly from the source language; if the language doesn’t have the Latin alphabet, Latinized name transcription is acceptable. Recommendations of the International Code of Nomenclature for Cultivated Plants that concern graphic highlighting of the cultivar names in the text enclosing them in single quotation marks and writing each word of a cultivar name with a capital letter should necessarily be applied in the foreign-language publications and extended to the Ukrainian special literature, at least, in terms of the use of single quotation marks. Ukrainian names should be transliterated only in accordance with the regulations.

The impact of age-related changes in visual-perceptual processing on naming ability has not been reported. The present study investigated the effects of 6 levels of spatial frequency and 6 levels of contrast on accuracy and latency to name objects in 14 young and 13 older neurologically normal adults with intact lexical-semantic functioning. Spatial frequency and contrast manipulations were made independently. Consistent with the hypotheses, variations in these two visual parameters impact naming ability in young and older subjects differently. The results from the spatial frequency-manipulations revealed that, in general, young vs. older subjects are faster and more accurate to name. However, this age-related difference is dependent on the spatial frequency on the image; differences were only seen for images presented at low (e.g., 0.25-1 c/deg) or high (e.g., 8-16 c/deg) spatial frequencies. Contrary to predictions, the results from the contrast manipulations revealed that overall older vs. young adults are more accurate to name. Again, however, differences were only seen for images presented at the lower levels of contrast (i.e., 1.25%). Both age groups had shorter latencies on the second exposure of the contrast-manipulated images, but this possible advantage of exposure was not seen for spatial frequency. Category analyses conducted on the data from this study indicate that older vs. young adults exhibit a stronger nonliving-object advantage for naming spatial frequency-manipulated images. Moreover, the findings suggest that bottom-up visual-perceptual variables integrate with top-down category information in different ways. Potential implications on the aging and naming (and recognition) literature are discussed.

Feeling-of-knowing for proper names.

Izaute, Marie; Chambres, Patrick; Larochelle, Serge

2002-12-01

The main objective of the presented study was to study feeling-of-knowing (FOK) in proper name retrieval. Many studies show that FOK can predict performance on a subsequent criterion test. Although feeling-of-knowing studies involve questions about proper names, none make this distinction between proper names and common names. Nevertheless, the specific character of proper names as a unique label referring to a person should allow participants to target precisely the desired verbal label. Our idea here was that the unique character of proper name information should result in more accurate FOK evaluations. In the experiment, participants evaluated feeling-of-knowing for proper and common name descriptions. The study demonstrates that FOK judgments are more accurate for proper names than for common names. The implications of the findings for proper names are briefly discussed in terms of feeling-of-knowing hypotheses.

It has been constructed the ozone generator by silent discharge method. Anode and cathode of discharge tube were made of stainless steel (SS) in the cylinder form with diameters of 22 mm and 25 mm, the length of 100 mm and 110 mm, the equal thickness of 1 mm respectively. The dielectric was made of cylinder glass with diameter of 23 cm, the length of 105 cm and the thickness of 1 mm. The testing of apparatus was carried out by using discharge voltage of 12.5 kV and frequency of 1.5 kHz. Identification of the ozone gas formation was marked by the existing of special ozone smell and the separated of iodine molecule (yellow colour) from the potassium iodide solution which contaminated gas out put from the ozonizer. By using absorbing method can be shown that the ozone production rate was 0.196 mg/s by using oxygen gas input and 0.065 mg/s by using ordinary air input. (author)

In countries where the private clinics of physicians can be freely named, registering a clinic with a physician's name is one way to make patients familiar with the physician. No previous study had investigated how clinics make use of this method of personal branding. Therefore, the current study analyzed 10,847 private physician Western medicine clinics in Taiwan. Of those clinics, 31.0% ( n = 3363) were named with a physician's full name, 8.9% ( n = 960) with a surname, and 8.1% ( n = 884) with a given name. The proportion of clinics registered with a physician's name was lower in rural areas (37.3%) than in urban (48.5%) and suburban areas (49.2%), respectively. Among clinics with only one kind of specialist, a physician's name was used most frequently in clinics of obstetrics and gynecology (64.9%), otorhinolaryngology (64.1%), and dermatology (63.4%). In Taiwan, fewer than half of clinics used a physician's name as a brand. The sociocultural or strategic factors and real benefits of doing so could be further studied in the future for a better understanding of healthcare services management.

The List of Available Names (LAN): A new generation for stable taxonomic names in zoology?

Science.gov (United States)

Alonso-Zarazaga, Miguel A; Fautin, Daphne Gail; Michel, Ellinor

2016-01-01

The List of Available Names in Zoology (LAN) is an inventory of names with specific scope in time and content, presented and approved in parts, and constituted as a cumulative index of names available for use in zoological nomenclature. It was defined in Article 79 in the fourth edition of the International Code of Zoological Nomenclature. The LAN is likely to gain importance with the development of the online Official Registry for Zoological Nomenclature (ZooBank) as it is potentially a source of many nomenclaturally certified names. Article 79 describes the deliberative process for adding large numbers of names to the LAN simultaneously, detailing steps and chronology for submission of a candidate Part to the LAN and consideration of a candidate Part by the public and Commission, but it is largely mute about the contents of a candidate Part. It does make clear that a name within the scope of a Part but not on the LAN has no nomenclatural standing, even if it had previously been considered available, thereby preventing long-forgotten names from displacing accepted ones and the accumulation of nomina dubia. Thus, for taxa on the LAN, nomenclatural archaeology - the resurrecting of old unused names to replace by priority names in current usage - will not be worthwhile. Beyond that, it has been unclear if Article 79 is intended to document every available name known within the scope of the Part, or if its intention is to pare the inventory of available names within the scope of the Part. Consideration by the Commission and two committees to deal with the LAN have defined steps to implement Article 79 with the latter intent. Procedures for consideration of a candidate Part are defined in a manual, published as an appendix in this volume.

Full Text Available There are numerous researches on color terms and names in many languages. In Mongolian language there are few doctoral theses on color naming. Cross cultural studies of color naming have demonstrated Semantic relevance in French and Mongolian color name Gerlee Sh. (2000; Comparisons of color naming across English and Mongolian Uranchimeg B. (2004; Semantic comparison between Russian and Mongolian idioms Enhdelger O. (1996; across symbolism Dulam S. (2007 and few others. Also a few articles on color naming by some Mongolian scholars are Tsevel, Ya. (1947, Baldan, L. (1979, Bazarragchaa, M. (1997 and others. Color naming studies are not sufficiently studied in Modern Mongolian. Our research is considered to be the first intended research on color naming in Modern Mongolian, because it is one part of Ph.D dissertation on color naming. There are two color naming categories in Mongolian, basic color terms and non- basic color terms. There are seven basic color terms in Mongolian. This paper aims to consider how Mongolian color names are derived from basic colors by using psycholinguistics associative experiment. It maintains the students and researchers to acquire the specific understanding of the differences and similarities of color naming in Mongolian and  English languages from the psycho-linguistic aspect.

Prevalence of symptomatic and silent stress-induced perfusion defects in diabetic patients with suspected coronary artery disease referred for myocardial perfusion scintigraphy

2005-01-01

Silent myocardial ischaemia - as evaluated by stress-induced perfusion defects on myocardial perfusion scintigraphy (MPS) in patients without a history of chest pain - is frequent in diabetes and is associated with increased rates of cardiovascular events. Its prevalence has been determined in asymptomatic diabetic patients, but remains largely unknown in diabetic patients with suspected coronary artery disease (CAD) in the clinical setting. In this study we therefore sought (a) to determine the prevalence of symptomatic and silent perfusion defects in diabetic patients with suspected CAD and (b) to characterise the eventual predictors of abnormal perfusion. The patient population comprised 133 consecutive diabetic patients with suspected CAD who had been referred for MPS. Studies were performed with exercise (41%) or pharmacological stress testing (1-day protocol, 99m Tc-sestamibi, 201 Tl or both). We used semi-quantitative analysis (20-segment polar maps) to derive the summed stress score (SSS) and the summed difference score (SDS). Abnormal MPS (SSS≥4) was observed in 49 (37%) patients (SSS=4.9±8.4, SDS=2.4±4.7), reversible perfusion defects (SDS≥2) in 40 (30%) patients [SSS=13.3±10.9; SDS=8.0±5.6; 20% moderate to severe (SDS>4), 7% multivessel] and fixed defects in 21 (16%) patients. Results were comparable between patients with and patients without a history of chest pain. Of 75 patients without a history of chest pain, 23 (31%, 95% CI=21-42%) presented reversible defects (SSS=13.9±11.3; SDS=7.4±1.2), indicative of silent ischaemia. Reversible defects were associated with inducible ST segment depression during MPS stress (odds ratio (OR)=3.2, p<0.01). Fixed defects were associated with erectile dysfunction in males (OR=3.7, p=0.02) and lower aspirin use (OR=0.25, p=0.02). Silent stress-induced perfusion defects occurred in 31% of the patients, a rate similar to that in patients with a history of chest pain. MPS could identify these patients with a

Naming asteroids for the popularisation of astronomy

Science.gov (United States)

Naranjo, O. A.

2008-06-01

We give a detailed description of how the naming of asteroids was used as a prize in competitions run by educational institutions and museums. There were two events, one in Venezuela and one in Brazil, which used this as an attractive alternative method for the popularisation of astronomy. The first competition, named Bautizo Espacial (Space Baptism), consisted of scientific stories written by high school students. The second, called Grande Desafio (Big Challenge), was a competition where teams of students were challenged to design and build prototype equipment to fight forest fires. Nationally, both events received wide publicity through newspapers, radio, TV and web pages, reaching many people in both countries. As part of both the events, several activities promoting the public knowledge of astronomy were held. The asteroids that were named in these competitions are just some of the many discovered in a search programme developed by the Group of Theoretical Astrophysics of University of Los Andes in Mérida, Venezuela (Grupo de Astrofisica Teórica de la Universidad de Los Andes) as a mainstream research programme. Finally, Asteroids for the Popularisation of Astronomy has been formally proposed to the IAU as a worldwide programme during the celebration of the International Year of Astronomy in 2009 (IYA2009).

2018-01-01

Full Text Available Stressful early life experiences cause immune dysregulation across the lifespan. Despite the fact that studies have identified childhood sexual abuse (CSA survivors as a particularly vulnerable group, only a few attempts have been made to study their lived-experience of the physical health consequences of CSA. The aim of this study was to explore a female CSA survivor’s lived-experience of the physical health consequences of CSA and how she experienced the reactions of healthcare providers. Seven interviews were conducted with this 40-year-old woman, Anne, using a phenomenological research approach. Anne was still a young child (two to three years old when her father started to rape her. Since her childhood, she has experienced complex and widespread physical health consequences such as repeated vaginal and abdominal infections, widespread and chronic pain, sleeping problems, digestive problems, chronic back problems, fibromyalgia, musculoskeletal problems, repeated urinary tract infections, cervical dysplasia, inflammation of the Fallopian tubes, menorrhagia, endometrial hyperplasia, chlamydia, ovarian cysts, ectopic pregnancies, uterus problems, severe adhesions, and ovarian cancer. Anne disclosed her CSA experience to several healthcare providers but they were silent and failed to provide trauma-informed care. Anne’s situation, albeit unique, might reflect similar problems in other female CSA survivors.

What’s In Your Name? Associated Meanings of the Common Filipino Names Among Young Filipinos

Full Text Available Name is important in knowing someone’s identity. By a person’s name someone can know his or her character. It is also possible that they bear a particular name because of their background and other factors that can lead to something important. This study aimed to find out the associative meanings of the most common Filipino male and female names among the Polytechnic University of the Philippines-Sta. Mesa students. Different factors such as character traits, physical appearance, and skills/talents were considered in determining meanings of the names. The study used quantitative and qualitative research approach, specifically the descriptive method, to analyze the gathered data. A selfadministered survey was distributed to 400 randomly selected respondents. General findings revealed that the respondents associated the most common Filipino male names in the same way regarding character traits and skills/talents. However, they have different associations to the male names in terms of physical appearance. On the other hand, the respondents associated the most common Filipino female names into similar character traits and physical appearance but associated them with different skills/talents. Results also revealed that the most common factors that influence the respondents’ associated meanings were relationships, experiences, popularity, and perception. The results imply that while young Filipinos associate similar character traits, physical appearances and skills to common Filipino names, they have different reasons in giving meanings to them.

Analyzing RTs, we replicated previous SI effects in BCN in healthy subjects and patients (reported effects’ p’s < .05. Subjects responded more slowly to items in semantically related vs. unrelated groups, and this interference increased across cycles (evidence of increasing selection demands; Figures 1a/c. Indicative of WM, healthy subjects were faster to name items as the number of unrelated items to be named (i.e., remembered decreased. However, this was attenuated by selection demand, as there was no decrease in RTs across repeated related items (Figure 1b. Converging evidence from patients demonstrated more impaired selection capacity produced increasingly slower RTs across item positions within the related condition (high selection demand (Figure 1d. Larger WM capacity (rhyme probe but not category probe, p = .54 produced increasingly faster RTs across items positions in the unrelated condition (low selection demand (Figure 1e. Together, these findings suggest that both selection demand and phonological WM processes mediate interference during naming.

Lengthened Cutaneous Silent Period in Fibromyalgia Suggesting Central Sensitization as a Pathogenesis.

Directory of Open Access Journals (Sweden)

Seol-Hee Baek

Full Text Available The pathogenesis of fibromyalgia (FM has not been clearly elucidated, but central sensitization, which plays an important role in the development of neuropathic pain, is considered to be the main mechanism. The cutaneous silent period (CSP, which is a spinal reflex mediated by A-delta cutaneous afferents, is useful for the evaluation of sensorimotor integration at the spinal and supraspinal levels. To understand the pathophysiology of FM, we compared CSP patterns between patients with FM and normal healthy subjects. Twenty-four patients with FM diagnosed in accordance with the 1990 American College of Rheumatology classification system and 24 age- and sex-matched healthy volunteers were recruited. The CSP was measured from the abductor pollicis brevis muscle. Demographic data, number of tender points, and visual analog scale and FM impact questionnaire scores were collected. The measured CSP and clinical parameters of the patient and control groups were compared. In addition, possible correlations between the CSP parameters and the other clinical characteristics were analyzed. Mean CSP latencies did not differ between patients (55.50 ± 10.97 ms and healthy controls (60.23 ± 11.87 ms; p = 0.158, although the mean CSP duration was significantly longer in patients (73.75 ± 15.67 ms than in controls (63.50 ± 14.05 ms; p = 0.021. CSP variables did not correlate with any clinical variables. The significantly longer CSP duration in FM patients suggests central dysregulation at the spinal and supraspinal levels, rather than peripheral small fiber dysfunction.

Tiger nut tubers have been reportedly used for the treatment of erectile dysfunction (ED) in folk medicine without scientific basis. Hence, this study evaluated the effect of tiger nut on erectile dysfunction by assessing biochemical parameters relevant to ED in male rats by nitric oxide synthase (NOS) inhibitor, Nω-nitro-l-arginine methyl ester hydrochloride (l-NAME) treatment. Rats were divided into five groups (n = 10) each: Control group; l-NAME plus basal diet; l-NAME plus Sildenafil citrate; diet supplemented processed tiger nut (20%) plus l-NAME;diet supplemented raw tiger nut (20%) plus l-NAME. l-NAME pre-treatment (40 mg/kg/day) lasted for 14 days. Arginase, acetycholinesterase (AChE) and adenosine deaminase (ADA) activities as well as nitric oxide levels (NO) in serum, brain and penile tissue were measured. l-NAME increased the activity of arginase, AChE and ADA and reduced NO levels. However, dietary supplementation with tiger nut caused a reduction on the activities of the above enzymes and up regulated nitric oxide levels when compared to the control group. The effect of tiger nut supplemented diet may be said to prevent alterations of the activities of the enzymes relevant in erectile function. Quercetin was revealed to be the most active component of tiger nut tuber by HPLC finger printing. Copyright © 2018. Published by Elsevier Ltd.

From Materials for A Dictionary of Russian Place Name Derivatives

Directory of Open Access Journals (Sweden)

Elizaveta O. Borisova

2013-12-01

Full Text Available The article presents some materials for a dictionary of Russian derivatives of place names belonging to dialects and the national language vocabulary and retrieved from various dictionaries (including The Dictionary of Russian Popular Dialects, The Dictionary of the Contemporary Russian Language, unpublished card indexes as well as from the Russian National Corpus. It is demonstrated that geographical names of Russia, namely, macrotoponyms (e. g., Sibir’ ‘Siberia’ → sibirka ‘a big piece of boiled meat’, Don ‘the Don river’ → donskaya shuba ‘a woman’s neat fur coat’ and microtoponyms (e. g., the Fedorovtsevskaya hole in Arkhangelsk region → fedorovtsevskiy kofey ‘a drink on the basis of polypore’ serve as productive stems for the derivatives in question. The lexicographic interpretation of the material is based on the thematic principle. The authors describe several thematic groups as being part of a wider group of words designating objects of material culture: “Clothes, footwear and head dress”, “Food and drinks”, “Agricultural instruments” and “Transport”. The authors indicate the toponymic stem of each derivative. The materials have an ethnolinguisitic value for being a source of ethnocultural information, as well as having an etymological and onomasiological significance.

Significance of using 'super' for naming a project of technological development is discussed. Functions of naming are classified into (1) recognition, (2) display and (3) sales-promotion, whereby mechanism of naming of merchandise that is developed through the technique of 3 is considered. Further, the mechanism of naming is discussed in relation to marketing. It is pointed out that naming of merchandise is determined on the basis of (1) concept of planned goods and (2) marketing-mixes composed of goods, price, sales-roots and sales-promotion. The same mechanism works also in a project for technological development. Technical trends are caught and projects are targetted by taking supposed regimes into account, thereby the most suitable mix is formed. The mix in the technological development is assumed to be composed of purpose, specification, regime and sales-promotion. Two examples of the governmental projects by Ministry of International Trade and Industry, 'the big regime for research and development on industrial technologies' and 'the regime for development of the fundamental technologies in the next generation' are introduced and the significance of their naming is described. 2 tabs.

A substantial research literature documents the effects of diverse item attributes, task conditions, and participant characteristics on the case of picture naming. The authors review what the research has revealed about 3 generally accepted stages of naming a pictured object: object identification, name activation, and response generation. They also show that dual coding theory gives a coherent and plausible account of these findings without positing amodal conceptual representations, and they identify issues and methods that may further advance the understanding of picture naming and related cognitive tasks.

Strickland-Hughes, Carla M; West, Robin Lea; Smith, Kimberly A; Ebner, Natalie C

2017-09-01

Feedback is an important self-regulatory process that affects task effort and subsequent performance. Benefits of positive feedback for list recall have been explored in research on goals and feedback, but the effect of negative feedback on memory has rarely been studied. The current research extends knowledge of memory and feedback effects by investigating face-name association memory and by examining the potential mediation of feedback effects, in younger and older adults, through self-evaluative beliefs. Beliefs were assessed before and after name recognition and name recall testing. Repeated presentation of false positive feedback was compared to false negative feedback and a no feedback condition. Results showed that memory self-efficacy declined over time for participants in the negative and no feedback conditions but was sustained for those receiving positive feedback. Furthermore, participants who received negative feedback felt older after testing than before testing. For name recall, the positive feedback group outperformed the negative feedback and no feedback groups combined, with no age interactions. The observed feedback-related effects on memory were fully mediated by changes in memory self-efficacy. These findings advance our understanding of how beliefs are related to feedback in memory and inform future studies examining the importance of self-regulation in memory.

Neural correlates of own name and own face detection in autism spectrum disorder.

2014-01-01

Autism spectrum disorder (ASD) is a heterogeneous neurodevelopmental condition clinically characterized by social interaction and communication difficulties. To date, the majority of research efforts have focused on brain mechanisms underlying the deficits in interpersonal social cognition associated with ASD. Recent empirical and theoretical work has begun to reveal evidence for a reduced or even absent self-preference effect in patients with ASD. One may hypothesize that this is related to the impaired attentional processing of self-referential stimuli. The aim of our study was to test this hypothesis. We investigated the neural correlates of face and name detection in ASD. Four categories of face/name stimuli were used: own, close-other, famous, and unknown. Event-related potentials were recorded from 62 electrodes in 23 subjects with ASD and 23 matched control subjects. P100, N170, and P300 components were analyzed. The control group clearly showed a significant self-preference effect: higher P300 amplitude to the presentation of own face and own name than to the close-other, famous, and unknown categories, indicating preferential attentional engagement in processing of self-related information. In contrast, detection of both own and close-other's face and name in the ASD group was associated with enhanced P300, suggesting similar attention allocation for self and close-other related information. These findings suggest that attention allocation in the ASD group is modulated by the personal significance factor, and that the self-preference effect is absent if self is compared to close-other. These effects are similar for physical and non-physical aspects of the autistic self. In addition, lateralization of face and name processing is attenuated in ASD, suggesting atypical brain organization.

Recognition of names of eminent psychologists.

Duncan, C P

1976-10-01

Faculty members, graduate students, undergraduate majors, and introductory psychology students checked those names they recognized in the list of 228 deceased psychologists, rated for eminence, provided by Annin, Boring, and Watson. Mean percentage recognition was less than 50% for the 128 American psychologists, and less than 25% for the 100 foreign psychologists, by the faculty subjects. The other three groups of subjects gave even lower recognition scores. Recognition was probably also influenced by recency; median year of death of the American psychologists was 1955, of the foreign psychologists, 1943. High recognition (defined as recognition by 80% or more of the faculty group) was achieved by only 34 psychologists, almost all of them American. These highly recognized psychologists also had high eminence ratings, but there was an equal number of psychologists with high eminence ratings that were poorly recognized.

A Doctor’s Name as a Brand: A Nationwide Survey on Registered Clinic Names in Taiwan

Full Text Available In countries where the private clinics of physicians can be freely named, registering a clinic with a physician’s name is one way to make patients familiar with the physician. No previous study had investigated how clinics make use of this method of personal branding. Therefore, the current study analyzed 10,847 private physician Western medicine clinics in Taiwan. Of those clinics, 31.0% (n = 3363 were named with a physician’s full name, 8.9% (n = 960 with a surname, and 8.1% (n = 884 with a given name. The proportion of clinics registered with a physician’s name was lower in rural areas (37.3% than in urban (48.5% and suburban areas (49.2%, respectively. Among clinics with only one kind of specialist, a physician’s name was used most frequently in clinics of obstetrics and gynecology (64.9%, otorhinolaryngology (64.1%, and dermatology (63.4%. In Taiwan, fewer than half of clinics used a physician’s name as a brand. The sociocultural or strategic factors and real benefits of doing so could be further studied in the future for a better understanding of healthcare services management.

Exploring historical trends using taxonomic name metadata

Schenk Ryan

2008-05-01

Full Text Available Abstract Background Authority and year information have been attached to taxonomic names since Linnaean times. The systematic structure of taxonomic nomenclature facilitates the ability to develop tools that can be used to explore historical trends that may be associated with taxonomy. Results From the over 10.7 million taxonomic names that are part of the uBio system 4, approximately 3 million names were identified to have taxonomic authority information from the years 1750 to 2004. A pipe-delimited file was then generated, organized according to a Linnaean hierarchy and by years from 1750 to 2004, and imported into an Excel workbook. A series of macros were developed to create an Excel-based tool and a complementary Web site to explore the taxonomic data. A cursory and speculative analysis of the data reveals observable trends that may be attributable to significant events that are of both taxonomic (e.g., publishing of key monographs and societal importance (e.g., world wars. The findings also help quantify the number of taxonomic descriptions that may be made available through digitization initiatives. Conclusion Temporal organization of taxonomic data can be used to identify interesting biological epochs relative to historically significant events and ongoing efforts. We have developed an Excel workbook and complementary Web site that enables one to explore taxonomic trends for Linnaean taxonomic groupings, from Kingdoms to Families.

Richardson, Jessica D; Dalton, Sarah Grace; Fromm, Davida; Forbes, Margaret; Holland, Audrey; MacWhinney, Brian

2018-03-01

The purpose of this study was to examine the relationship between picture naming performance and the ability to communicate the gist, or essential elements, of a story. We also sought to determine if this relationship varied according to Western Aphasia Battery-Revised (WAB-R; Kertesz, 2007) aphasia subtype. Demographic information, test scores, and transcripts of 258 individuals with aphasia completing 3 narrative tasks were retrieved from the AphasiaBank database. Narratives were subjected to a main concept analysis to determine gist production. A correlation analysis was used to investigate the relationship between naming scores and main concept production for the whole group of persons with aphasia and for WAB-R subtypes separately. We found strong correlations between naming test scores and narrative gist production for the large sample of persons with aphasia. However, the strength of the correlations varied by WAB-R subtype. Picture naming may accurately predict gist production for individuals with Broca's and Wernicke's aphasia, but not for other WAB-R subtypes. Given the current reprioritization of outcome measurement, picture naming may not be an appropriate surrogate measure for functional communication for all persons with aphasia. https://doi.org/10.23641/asha.5851848.

1993-01-01

We examined the relationship between pre-senile, senile depressive states and silent cerebral infarction (SCI) using magnetic resonance imaging (MRI). The diagnostic criteria of major depression according to DSM-3-R was used to diagnose. Patients in whom stroke had occurred or who had local neurologic symptoms were not included. About half of the patients with depressive states of pre-senile onset and most of the patients with those of senile onset had SCI, were considered to be organic-depressive states complicated with SCI. Because patients with depressive states with SCI are at high risk of occurrence of stroke, we designated this condition 'pre-stroke depression', and classified it with endogenous depression. At this time, it is important to begin therapy for cerebrovascular disease. (author)

Visual object naming in patients with small lesions centered at the left temporopolar region.

Campo, Pablo; Poch, Claudia; Toledano, Rafael; Igoa, José Manuel; Belinchón, Mercedes; García-Morales, Irene; Gil-Nagel, Antonio

2016-01-01

Naming is considered a left hemisphere function that operates according to a posterior-anterior specificity gradient, with more fine-grained information processed in most anterior regions of the temporal lobe (ATL), including the temporal pole (TP). Word finding difficulties are typically assessed using visual confrontation naming tasks, and have been associated with selective damage to ATL resulting from different aetiologies. Nonetheless, the role of the ATL and, more specifically, of the TP in the naming network is not completely established. Most of the accumulated evidence is based on studies on patients with extensive lesions, often bilateral. Furthermore, there is a considerable variability in the anatomical definition of ATL. To better understand the specific involvement of the left TP in visual object naming, we assessed a group of patients with an epileptogenic lesion centered at the TP, and compared their performance with that of a strictly matched control group. We also administered a battery of verbal and non-verbal semantic tasks that was used as a semantic memory baseline. Patients showed an impaired naming ability, manifesting in a certain degree of anomia and semantically related naming errors, which was influenced by concept familiarity. This pattern took place in a context of mild semantic dysfunction that was evident in different types and modalities of semantic tasks. Therefore, current findings demonstrate that a restricted lesion to the left TP can cause a significant deficit in object naming. Of importance, the observed semantic impairment was far from the devastating degradation observed in semantic dementia and other bilateral conditions.

Current Trends in Name Giving among Bulgarians: A Study of the Names of Newborns in the Sofia Region

Maya Vlahova-Angelova

2017-11-01

Full Text Available The article showcases a large-scale study of the modern Bulgarian anthroponymic system conducted by the Applied Onomastics section of the Bulgarian Academy of Sciences Institute for the Bulgarian Language (IBL with the aim of revealing the current trends in the choice of personal names by the Bulgarians at the beginning of the 21st century. The study focuses on personal names of Bulgarians born in 2010 in the Sofia region, as extracted from the Unified System of Civil Registration and Administrative Services of the Population of the Republic of Bulgaria. The total number of births this year was 1,005, of which 51.5% were boys, 48.5% were girls. Statistical and linguistic analysis of names allowed to measure the popularity of both individual personal names and different name types. It shows the quantitative ratio between most commonly chosen names and those of a singular use in relation to the total number of anthroponyms in the corpus, and proves that the male names are more sustainable in terms of usage than female. The derivational and etymological analysis of personal names helped to identify the productive word-formation types of names and the so-called “unisex names,” to distinguish between the native Bulgarian and the borrowed foreign names, as well as to classify graphic and phonetic variants of the same anthroponym. A number of quantitative comparisons were made between certain categories of names, for example, between compound (two-stem personal names (such as Miroslav and simple names (such as Biser, showing the ratio of the two-component personal names (such as Anna-Maria to the rest of the anthroponyms. It was found that the Bulgarian anthroponymic system in the beginning of the 21st century is more open to the non-adapted foreign names (like Mishel, Nancy, shows wider usage of diminutive “unisex names” (Moni, Stephy, Toni, as well as the growing popularity of shortened forms used as official names (Alex, Boni, Pepi, and the

The role of ion irradiation in activating silent Raman modes via tuning in plasmonic behaviour and surface disorder of Au/ZnO/Pt NFG system

Science.gov (United States)

Singh, Udai B.; Gautam, Subodh K.; Kumar, Sunil; Ojha, Sunil; Ghosh, Santanu; Singh, Fouran

2017-09-01

The perceptible progression of Raman modes of zinc oxide (ZnO) is studied in nanostructures film gap (Au (10 nm)/ZnO (70 nm)/Pt (50 nm)) system with 1.2 MeV Xe ion irradiation. Unattainable silent Raman modes of ZnO turn out to be strongly visible after ion irradiation. The creation of ion-beam-induced lattice disorder, defects, and impurities in a ZnO layer leads to breakdown the translational crystal symmetry that results in the origin of silent modes. The formation of hot-spots in the ZnO layer of the NFG system also supports the enhancement of the intensity of Raman modes. Overall results are attributed to combined effects of lattice disorder, defects, and impurities along with plasmonic effect and explained in the framework of elastic-thermal-spike formation.

Names are more difficult to remember than other personal information such as occupations. The current research examined the influence of assigned point value on memory and metamemory judgements for names and occupations to determine whether incentive can improve recall of proper names. In Experiment 1 participants studied face-name and face-occupation pairs assigned 1 or 10 points, made judgements of learning, and were given a cued recall test. High-value names were recalled more often than low-value names. However, recall of occupations was not influenced by value. In Experiment 2 meaningless nonwords were used for both names and occupations. The name difficulty disappeared, and value influenced recall of both names and occupations. Thus value similarly influenced names and occupations when meaningfulness was held constant. In Experiment 3 participants were required to use overt rote rehearsal for all items. Value did not boost recall of high-value names, suggesting that differential processing could not be implemented to improve memory. Thus incentives may improve memory for proper names by motivating people to engage in selective rehearsal and effortful elaborative processing.

Treatment of Egyptian Maghara coal by plasma ozone synthesized by silent discharge

A sample of pyrite rich bituminous coal collected from the main coal seam of Maghara mine, northern sinai, was treated by ozone plasma. The latter was synthesized using silent discharge method (10 kv a.c. and 50 hz). The room temperature Moessbauer spectra of untreated coal sample was easily fitted to two doublet, whose parameters matched those of pyrite (FeS sub 2) and sulfate (FeSO sub 4.H sub 2 O) in addition to hematite. After treatment by ozone plasma, a doublet ascribed to pyrite was observed. The extent of pyrite oxidation to jarosite (Fe sub 2 (SO sub 4) sub 3. nH sub 2 O) was monitored by their relative spectral areas, the incomplete oxidation of pyrite may be attributed to the presence of calcium sulfate layer which acts a screen of ozone.

Clinically silent subdural hemorrhage causes bilateral vocal fold paralysis in newborn infant.

2012-10-01

Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology. Copyright © 2012. Published by Elsevier Ireland Ltd.

This paper presents a method for creating a model of the wind power plant NORDEX N-60 in the DIgSILENT Power factory software. At the beginning, the characteristics of the wind power plant and the used software are shortly described. The next step is modeling the part of the power system where the wind power plant will be connected to the grid The modeling of the turbine part and the generator part of the wind power plant is made with blocks, which are part of the machine block of the composite model. Finally, the results obtained from performed practically oriented simulations are presented in graphical form. Design of the model of the wind power plant NORDEX N-60 was performed at the Faculty of Electrical Engineering, at the University of Rostock, Germany, as a part of the DYSIMAC project. (Author)

Lithium toxicity precipitated by thyrotoxicosis due to silent thyroiditis: cardiac arrest, quadriplegia, and coma.

Lithium is widely used to treat bipolar disorders. Lithium toxicity is generally caused by inappropriately high doses of lithium or impaired lithium excretion. Most lithium is eliminated via the kidneys and, since thyroid hormone increases tubular reabsorption of lithium, thyrotoxicosis could contribute to the development of lithium toxicity. We report a case of severe lithium toxicity that was apparently precipitated by the onset of thyrotoxicosis resulting from silent thyroiditis and dehydration. The patient was a 64-year-old woman who was admitted for muscle weakness in the lower extremities, diarrhea, and palpitations. She had bipolar disorder and was being treated with lithium carbonate, which she discontinued one week before admission. Her circulating lithium levels had been monitored yearly. Early in her admission she was dehydrated and had febrile episodes, paroxysmal atrial fibrillation, and muscle weakness. Initially, fluid therapy was started, but she lost consciousness and had a cardiac arrest for 2 minutes due to prolonged sinus arrest. Chest compression and manual artificial ventilation were performed, and body surface pacing was started. Serum lithium was markedly elevated to 3.81 mEq/L (therapeutic range, 0.4-1.0 mEq/L), and thyroid hormone levels were increased (free triiodothyronine, 8.12 pg/mL; free thyroxine, 4.45 ng/dL), while thyrotropin (TSH) was suppressed (quadriplegia and deep coma. She gradually recovered. On day 36, she was discharged without any neurological symptoms or thyrotoxicosis. A 64-year-old woman taking lithium for bipolar disorder developed lithium toxicity in the setting of what seemed likely to be a recent onset of thyrotoxicosis due to silent thyroiditis. Thyrotoxicosis may be a contributing cause of lithium toxicity, particularly if it is abrupt in onset and even with cessation of lithium therapy if renal function is compromised. Thyroid function should be assessed immediately in patients with suspected lithium

Neural correlates of own name and own face detection in autism spectrum disorder.

Directory of Open Access Journals (Sweden)

Hanna B Cygan

Full Text Available Autism spectrum disorder (ASD is a heterogeneous neurodevelopmental condition clinically characterized by social interaction and communication difficulties. To date, the majority of research efforts have focused on brain mechanisms underlying the deficits in interpersonal social cognition associated with ASD. Recent empirical and theoretical work has begun to reveal evidence for a reduced or even absent self-preference effect in patients with ASD. One may hypothesize that this is related to the impaired attentional processing of self-referential stimuli. The aim of our study was to test this hypothesis. We investigated the neural correlates of face and name detection in ASD. Four categories of face/name stimuli were used: own, close-other, famous, and unknown. Event-related potentials were recorded from 62 electrodes in 23 subjects with ASD and 23 matched control subjects. P100, N170, and P300 components were analyzed. The control group clearly showed a significant self-preference effect: higher P300 amplitude to the presentation of own face and own name than to the close-other, famous, and unknown categories, indicating preferential attentional engagement in processing of self-related information. In contrast, detection of both own and close-other's face and name in the ASD group was associated with enhanced P300, suggesting similar attention allocation for self and close-other related information. These findings suggest that attention allocation in the ASD group is modulated by the personal significance factor, and that the self-preference effect is absent if self is compared to close-other. These effects are similar for physical and non-physical aspects of the autistic self. In addition, lateralization of face and name processing is attenuated in ASD, suggesting atypical brain organization.

Cutaneous silent period (CSP) is an inhibitory spinal protective reflex and its afferents consist of A-delta nerve fibers. We aimed to evaluate patients with fibromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine whether there is any relationship with disease characteristics, psychological disorders and quality of life. Thirty-two patients with FM and 32 healthy volunteers were included in the study. The patient and control groups were compared in terms of CSP latency and duration in both upper and lower extremities. Disease characteristics, psychological disorders and quality of life of patients were assessed using the Fibromyalgia Impact Questionnaire (FIQ) and Short Form-36 (SF-36). Patients with CSP measurements equal to or lower than those of the control group were compared with those with higher values than controls in terms of disease characteristics, psychological status and quality of life. Significantly prolonged CSP latencies in both upper and lower extremities were determined in patients compared to controls. We found that prolongation of CSP latency in the lower extremity is associated with disease severity and functional disability. CSP latencies in both upper and lower extremities in patients with FM are longer than in healthy volunteers. Moreover, prolongation of CSP latency in the lower extremity is associated with disease severity and physical functional disability.

This paper demonstrates the results of implementation and verification of an already existing algorithm that allows for calculating saturation characteristics of singlephase power transformers. The algorithm was described for the first time in 1993. Now this algorithm has been implemented using...... the DIgSILENT Programming Language (DPL) as an external script in the harmonic domain calculations of a power system analysis tool PowerFactory [10]. The algorithm is verified by harmonic measurements on a single-phase power transformer. A theoretical analysis of the core nonlinearities phenomena...... in single and three-phase transformers is also presented. This analysis leads to the conclusion that the method can be applied for modelling nonlinearities of three-phase autotransformers....

Arterial hypertension is a multifactorial chronic condition caused by either congenital or acquired factors. To evaluate the effects of Resistance Training (RT) on arterial pressure, and on vascular reactivity and morphology, of L-NAME-treated hypertensive rats. Male Wistar rats (200 - 250 g) were allocated into Sedentary Normotensive (SN), Sedentary Hypertensive (SH) and Trained Hypertensive (TH) groups. Hypertension was induced by adding L-NAME (40 mg/Kg) to the drinking water for four weeks. Arterial pressure was evaluated before and after RT. RT was performed using 50% of 1RM, 3 sets of 10 repetitions, 3 times per week for four weeks. Vascular reactivity was measured in rat mesenteric artery rings by concentration-response curves to sodium nitroprusside (SNP); phenylephrine (PHE) was also used for histological and stereological analysis. Resistance training inhibited the increase in mean and diastolic arterial pressures. Significant reduction was observed in Rmax (maximal response) and pD2 (potency) of PHE between SH and TH groups. Arteries demonstrated normal intima, media and adventitia layers in all groups. Stereological analysis demonstrated no significant difference in luminal, tunica media, and total areas of arteries in the SH and TH groups when compared to the SN group. Wall-to-lumen ratio of SH arteries was significantly different compared to SN arteries (parteries. RT was able to prevent an increase in blood pressure under the conditions in this study. This appears to involve a vasoconstrictor regulation mechanism and maintenance of luminal diameter in L-NAME induced hypertensive rats.

[Old English plant names from the linguistic and lexicographic viewpoint].

Science.gov (United States)

Sauer, Hans; Krischke, Ulrike

2004-01-01

Roughly 1350 Old English plant names have come down to us; this is a relatively large number considering that the attested Old English vocabulary comprises ca. 24 000 words. The plant names are not only interesting for botanists, historians of medicine and many others, but also for philologists and linguists; among other aspects they can investigate their etymology, their morphology (including word-formation) and their meaning and motivation. Practically all Old English texts where plant names occur have been edited (including glosses and glossaries), the names have been listed in the Old English dictionaries, and some specific studies have been devoted to them. Nevertheless no comprehensive systematic analysis of their linguistic structure has been made. Ulrike Krischke is preparing such an analysis. A proper dictionary of the Old English plant names is also a desideratum, especially since the Old English dictionaries available and in progress normally do not deal with morphological and semantic aspects, and many do not provide etymological information. A plant-name dictionary concentrating on this information is being prepared by Hans Sauer and Ulrike Krischke. In our article here, we sketch the state of the art (ch. 1), we deal with some problems of the analysis of Old English plant names (ch. 2), e.g. the delimitation of the word-field plant names, the identification of the plants, errors and problematic spellings in the manuscripts. In ch. 3 we sketch the etymological structure according to chronological layers (Indo-European, Germanic, West-Germanic, Old English) as well as according to the distinction between native words and loan-words; in the latter category, we also mention loan-formations based on Latin models. In ch. 4 we survey the morphological aspects (simplex vs. complex words); among the complex nouns, compounds are by far the largest group (and among those, the noun + noun compounds), but there are also a few suffix formations. We also briefly

JIHADIST GROUPS IN THE SAHEL. AN ETYMOLOGICAL ANALYSIS

Directory of Open Access Journals (Sweden)

Francesco Saverio Angió

2018-01-01

Full Text Available The names of the insurgent groups include historical, cultural, ethnic, territorial and doctrinal references that appear too specific to be considered accidental and thus could be indicative of their strategy. The examples of terrorist attacks carried out by these groups support this argument, as they adopted or changed their name beforehand, shortly before a spinoff group, a new alliance or an offshoot emerged, or when an attack occurred in a non-traditional geographic area of action. Unfortunately, too often mass media and government officials utilise incorrect and/or superficial translations of these names, thus contributing to a lack of detailed information on the jihadists. The etymological analysis of the Arabic names of the Sahelian jihadist insurgents intends to and contributes to increase the knowledge on the nature and actions of these groups

J-PARC (Japan Proton Accelerator Research Complex) accelerator devices are controlled by the use of the software called EPICS (Experimental Physics and Industrial Control System). The unique name called an EPICS record is given to a control signal and data acquisition, Accelerator device control is achieved using the EPICS record. The requirement for the EPICS record name is 2 points; (1) no overlap of the EPICS record name, (2) the control contents can be easily imagined from the EPICS record name. To manage the EPICS record using relational database for the information management of the accelerator device in J-PARC, the naming structure is required so that a mechanical process can be performed easily. It was necessary to standardize the EPICS record name and the EPICS record structure to achieve these requirements. Therefore, we have formulated a guideline called 'EPICS record naming conventions' to decide to an EPICS record name uniquely and standardization. The abbreviated key word list of the accelerator devices and the control signal that compose the EPICS record name is appended to the EPICS record naming conventions. (author)

The history of Latin teeth names.

Science.gov (United States)

Šimon, František

2015-01-01

This paper aims to give an account of the Latin naming of the different types of teeth by reviewing relevant historical and contemporary literature. The paper presents etymologies of Latin or Greek teeth names, their development, variants and synonyms, and sometimes the names of their authors. The Greek names did not have the status of official terms, but the Latin terms for particular types of teeth gradually established themselves. Names for the incisors, canines and molars are Latin calques for the Greek ones (tomeis, kynodontes, mylai), dens serotinus is an indirect calque of the Greek name (odús) opsigonos, and the term pre-molar is created in the way which is now common in modern anatomical terminology, using the prefix prae- = pre and the adjective molaris. The Latin terms dentes canini and dentes molares occur in the Classical Latin literature, the term (dentes) incisivi is found first time in medieval literature, and the terms dentes premolares and dens serotinus are modern-age ones.

Silent Revolution in Research for Sustainability

Directory of Open Access Journals (Sweden)

Bruce Alder

2016-06-01

Full Text Available Is research ‘fit-for-purpose’ for realizing sustainable development? More than two decades after the Brundtland report and UNCED Earth summit, the world has now adopted Sustainable Development Goals(SDGs. Rather than a cause for celebration, this delay should encourage reflection on the role of research in society. Why is it so difficult to realize sustainability in practice? The answer lies in the fact that universities and research centres persist with 19th century methods of data gathering, scholarly analysis, and journal articles. Today’s world needs science in real-time, whether to detect drought, confront Ebola, or assist refugees. Research needs to work faster and embrace 21st century practices including data science, open access, and infographics.A silent revolution is occurring in the ways of organizing and conducting research, enabled by new technology and encouraging work that tackles the key challenges facing society. A variety of new arrangements have come into existence that promote international collaboration, including Horizon 2020 with its emphasis on societal challenges, the Bill & Melinda Gates Foundation which has inspired a family of grand challenges funds on health and development, and the Future Earth joint program of research for global sustainability. These arrangements not only control billions of dollars in research funding, they also influence the strategies of national research councils and international organizations. The result is no less than a transformation in the incentives that reward how researchers invest their time and effort.Why is a revolution needed? Within research, substantial growth in knowledge production coincided with fragmentation among disciplines. One can easily find expertise and publications in soil science or agronomy, yet integrated efforts on food security and climate adaptation remain scarce. Beyond research, society remains largely uninformed, as academics avoid engaging in public

Nominal ISOMERs (Incorrect Spellings Of Medicines Eluding Researchers)-variants in the spellings of drug names in PubMed: a database review.

Ferner, Robin E; Aronson, Jeffrey K

2016-12-14

 To examine how misspellings of drug names could impede searches for published literature.  Database review.  PubMed.  The study included 30 drug names that are commonly misspelt on prescription charts in hospitals in Birmingham, UK (test set), and 30 control names randomly chosen from a hospital formulary (control set). The following definitions were used: standard names-the international non-proprietary names, variant names-deviations in spelling from standard names that are not themselves standard names in English language nomenclature, and hidden reference variants-variant spellings that identified publications in textword (tw) searches of PubMed or other databases, and which were not identified by textword searches for the standard names. Variant names were generated from standard names by applying letter substitutions, omissions, additions, transpositions, duplications, deduplications, and combinations of these. Searches were carried out in PubMed (30 June 2016) for "standard name[tw]" and "variant name[tw] NOT standard name[tw]."  The 30 standard names of drugs in the test set gave 325 979 hits in total, and 160 hidden reference variants gave 3872 hits (1.17%). The standard names of the control set gave 470 064 hits, and 79 hidden reference variants gave 766 hits (0.16%). Letter substitutions (particularly i to y and vice versa) and omissions together accounted for 2924 (74%) of the variants. Amitriptyline (8530 hits) yielded 18 hidden reference variants (179 (2.1%) hits). Names ending in "in," "ine," or "micin" were commonly misspelt. Failing to search for hidden reference variants of "gentamicin," "amitriptyline," "mirtazapine," and "trazodone" would miss at least 19 systematic reviews. A hidden reference variant related to Christmas, "No-el", was rare; variants of "X-miss" were rarer.  When performing searches, researchers should include misspellings of drug names among their search terms.

Exploration history and place names of northern East Greenland: Colophon, abstract, introduction, official place names in Greenland

Directory of Open Access Journals (Sweden)

Higgins, Anthony K.

2010-12-01

Full Text Available The first recorded landing by Europeans on the coast of northern East Greenland (north of 69°N was that of William Scoresby Jr., a British whaler, in 1822. This volume includes a chronological summary of the pioneer 19th century exploration voyages made by British, Danish, Norwegian, Swedish, French and German expeditions – all of whom reported that the region had previously been occupied by the Inuit or Eskimo; also included are brief outlines of the increasing number of government and privately sponsored expeditions throughout the 20th century, whose objectives included cartography, geology, zoology, botany, trapping and the ascent of the highest mountain summits. In 1934 the Place Name Committee for Greenland was established, the tasks of which included a review of all place names hitherto recorded on published maps of Greenland, their formal adoption in danicised form, and the approval or rejection of new name proposals. In northern East Greenland, by far the largest numbers of new place names were those proposed by scientists associated with Lauge Koch’s geological expeditions that lasted from 1926 until 1958. This volume records the location and origin of more than 3000 officially approved place names as well as about 2650 unapproved names.The author’s interest in the exploration history and place names of northern East Greenland started in 1968, when the Geological Survey of Greenland initiated a major five-year geological mapping programme in the Scoresby Sund region. Systematic compilation of names began about 1970, initially with the names given by William Scoresby Jr., and subsequently broadened in scope to include the names proposed by all expeditions to northern East Greenland. The author has participated in 16 summer mapping expeditions with the Survey to northern East Greenland. Publication of this volume represents the culmination of a lifetime working in the Arctic.

On the History of the Name Ruslan

Directory of Open Access Journals (Sweden)

Roza Yu. Namitokova

2016-12-01

Full Text Available The authors postulate that there exists a common stock of Russian personal names resulting from a partial blending of national anthroponymicons. The main part of the paper focuses on the history of the personal name Ruslan which has etymological ties with the widespread Turkic name Arslan having the pre-onomastic meaning ‘lion’. The authors study the variation of the name in Russian folklore and in the 15th–17th centuries documents and historical sources. They also pay particular attention to the role of Pushkin’s poem Ruslan and Ludmila in the formation of the associative background of the studied name and to various onomastic derivatives, the latter include patronyms, surnames and the female name Ruslana. The author conclude that the name Ruslan became especially popular in Soviet and post-Soviet periods when it acquired a specific “semantic aura”, namely, in Caucasus where Ruslan became a kind of mark of Russian identity and, thus, contributed to the unification of the anthroponymic space. This conclusion was verified in the course of a survey done among 40 respondents representing different peoples of Caucasus. For most respondents the name has positive connotations and is associated with the Turkic name Arslan and the name of Pushkin’s character. However, some respondents consider it as a “non-Muslim”, Russian name and point out that it is often perceived as such outside Russia. The history of the name Ruslan and the ways of its transonymisation can be an interesting object for further research, especially due to the emergence of new communication technologies and onomastic discourses.

Directory of Open Access Journals (Sweden)

Kecskés, Judit

2013-12-01

Full Text Available Based on research done in 2012, this paper presents how immigrant children educated in present- day Hungarian public schools are named, paying special attention to name assimilation and acculturation. Describing the characteristic features of given names and changes in name order is important, because it may offer a basis for a better understanding of Hungarian historical onomastic sources concerning the name use of immigrant groups. This research proves that the Hungarian name order (family name + given name is extremely influential today and shows no sign of ethnic dependence in administrative or school communication. Inclination toward assimilation displayed in the choice of the given name, in most cases, appears in informal names, and affects official names only to a lesser degree. Functionally, the informal names are names for the child, usually chosen by a parent or the child him- or herself. Mostly, these names are acknowledged Hungarian given names, coinciding with those used in contemporary Hungarian communities; a small proportion of the names under discussion, however, are morphologically modified forms, in which the function of the present-day Hungarian diminutive suffix is presumably misinterpreted by the name bearers.

Lexical Retrieval is not by Competition: Evidence from the Blocked Naming Paradigm

Science.gov (United States)

Navarrete, Eduardo; Del Prato, Paul; Peressotti, Francesca; Mahon, Bradford Z.

2014-01-01

A central issue in research on speech production is whether or not the retrieval of words from the mental lexicon is a competitive process. An important experimental paradigm to study the dynamics of lexical retrieval is the blocked naming paradigm, in which participants name pictures of objects that are grouped by semantic category (‘homogenous’ or ‘related’ blocks) or not grouped by semantic category (‘heterogeneous’ or ‘unrelated’ blocks). Typically, pictures are repeated multiple times (or cycles) within both related and unrelated blocks. It is known that participants are slower in related than in unrelated blocks when the data are collapsed over all within-block repetitions. This semantic interference effect, as observed in the blocked naming task, is the strongest empirical evidence for the hypothesis of lexical selection by competition. Here we show, contrary to the accepted view, that the default polarity of semantic context effects in the blocked naming paradigm is facilitation, rather than interference. In a series of experiments we find that interference arises only when items repeat within a block, and only because of that repetition: What looks to be ‘semantic interference’ in the blocked naming paradigm is actually less repetition priming in related compared to unrelated blocks. These data undermine the theory of lexical selection by competition and indicate a model in which the most highly activated word is retrieved, regardless of the activation levels of nontarget words. We conclude that the theory of lexical selection by competition, and by extension the important psycholinguistic models based on that assumption, are no longer viable, and frame a new way to approach the question of how words are retrieved in spoken language production.

2015-12-01

Full Text Available The article presents an analysis of precedent names as symbols of precedent phenomena in the material and spiritual culture of the Chinese. An evaluation of daily events and the attitude of the Chinese towards the world are reflected in the vocabulary of their language. The symbols of precedent phenomena can be proper names (anthroponomy, names of places, the date, as well as figurative and expressive means of language (idioms, sayings. Precedent names as symbols of precedent phenomena vividly and accurately capture the above-mentioned points, and encompass almost all spheres of life, history and spiritual development. The subject of our study are national precedent phenomena that define the ethno-cultural specificity, reflecting the history and culture of the Chinese people and their national character. Representatives of different cultures have different perceptions of the same precedent phenomena. Inadequate understanding of national invariants of precedent phenomena is often the source of communication failures. The aim of this paper is to highlight precedent names as a symbol of precedent phenomena in the discourse of the Chinese linguocultural community. For this purpose a classification of precedent names in Chinese was carried out. Precedent names which play an important role in shaping the Chinese national consciousness were taken from the Chinese-Russian Dictionary.

Full Text Available Toponyms localize, reflect and give information about historical traditions and various phenomena in an area. They form part of the local heritage and culture. The relationship between place names, heritage and identity is often underlined in guidelines regarding official naming of streets and roads. In what way is heritage and local identity reflected in the road names of the three municipalities Hå, Klepp and Time (Southwest-Norway, and how is the special character of this area expressed in the names? More than half of the official road names in the three municipalities are either identical with a local toponym, or they consist of a word for ‘road’ and a local toponym (or an appellative describing the location. This shows that there is a strong commitment to base the official naming on local tradition and thus contribute to identity. Quite a few elements from the dialect, e.g. special pronunciation, grammatical forms or local words, appear in the names, especially in the road names from Hå, reflecting that the names are part of the local culture, and due to the fact that the dialect is unique. Consistency is a challenge, however; the same word is sometimes spelled in different ways in different names. It appears that, with some exceptions, cultural heritage and local tradition have been preferred principles and guidelines with regard to naming of roads in the three municipalities, due to a consciousness that heritage and tradition create identity.

On the correct name for some subfamilies of Mustelidae (Mammalia, Carnivora

Fabio Oliveira do Nascimento

2014-01-01

Full Text Available Mustelids (Mustelidae exhibit a wide morphological and ecological diversity, ranging from aquatic to semi arboreal and fossorial forms. It is the most diversity family in Carnivora, and this has promoted a great number of taxonomic arrangements for subfamilies, which can range from two to 15 depending on the author. The relatively recent use of molecular data has helped to elucidate the classification of mustelids, and eight subfamilies are currently recognized: Mustelinae, Galictinae, Helictidinae, Martinae, Melinae, Mellivorinae, Taxidiinae and Lutrinae. However, some of these subfamilies have nomenclatural problems, not receiving the oldest available name. The subfamily that includes martens (Martes, Charronia and Pekania, tayra (Eira and wolverine (Gulo has received the name of Martinae Wagner, 1841, but the oldest available name is Guloninae Gray, 1825. This problem also occurs for the subfamily that includes the grisons (Galictis, Patagonian weasel (Lyncodon, marbled polecat (Vormela and striped weasels (Ictonyx and Poecilogale, which are known as Grisoninae Pocock, 1921, but the correct name for this group is Ictonychinae, Pocock, 1921. The subfamily that includes ferret badgers (Melogale retains the name Helictidinae Gray, 1865, because its validity is not affected when the type-genus of the subfamily becomes a junior synonym of another genus. Furthermore, a list of the extant subfamilies of Mustelidae and their respective synonyms and included genera is provided.

Full Text Available Branding is considered to be particularly important in the marketing of online educational programs. A critical step to establishing the brand is naming the product appropriately. To this end, one can secure the services of professionals or rely on a do-it-yourself approach. The research reported here aimed to identify the features that non-professionals (graduate students consider to be important in the name for an online educational product, and to compare these to the recommendations made by naming professionals (as reported in the literature. A survey directed at current and prospective graduate students at a traditional university asked about the desirability of 16 characteristics in the name of a new line of online courses. The six characteristics that were deemed most critical are (in order of importance: self-explanatory, memorable, easy to pronounce, has appealing associations, suggests/hints at the key features, and short. These are the same features that professionals in the business of creating new product names generally consider as best practices in creating a name. The results show that contrary to the concerns expressed by some practitioners in the naming industry, college-educated individuals who do not create names for a living nonetheless demonstrate an awareness and appreciation for the features of a good name in an Internet-based course delivery system.

Ethnolinguistic studies are important for understanding an ethnic group's ideas on the world, expressed in its language. Comparing corresponding aspects of such knowledge might help clarify problems of origin for certain concepts and words, e.g. whether they form common heritage, have an independent origin, are borrowings, or calques. The current study was conducted on the material in Slavonic, Baltic, Germanic, Romance, Finno-Ugrian, Turkic and Albanian languages. The bear was chosen as being a large, dangerous animal, important in traditional culture, whose name is widely reflected in folk plant names. The phytonyms for comparison were mostly obtained from dictionaries and other publications, and supplemented with data from databases, the co-authors' field data, and archival sources (dialect and folklore materials). More than 1200 phytonym use records (combinations of a local name and a meaning) for 364 plant and fungal taxa were recorded to help find out the reasoning behind bear-nomination in various languages, as well as differences and similarities between the patterns among them. Among the most common taxa with bear-related phytonyms were Arctostaphylos uva-ursi (L.) Spreng., Heracleum sphondylium L., Acanthus mollis L., and Allium ursinum L., with Latin loan translation contributing a high proportion of the phytonyms. Some plants have many and various bear-related phytonyms, while others have only one or two bear names. Features like form and/or surface generated the richest pool of names, while such features as colour seemed to provoke rather few associations with bears. The unevenness of bear phytonyms in the chosen languages was not related to the size of the language nor the present occurence of the Brown Bear in the region. However, this may, at least to certain extent, be related to the amount of the historical ethnolinguistic research done on the selected languages.

Hepatitis B is frequent in the Philippines. A high rate of immigration to the United States has brought many Filipinos with infections who are asymptomatic yet will go on to develop liver cancer and cirrhosis unless diagnose and evaluated. Interventions are necessary to educate this ethnic community, identify those infected, and offer therapy. In an effort to reach this high risk population in Hawai'i an intervention program was designed to address the silent epidemic of hepatitis. Ethnic barriers were crossed through involvement of trusted, key stakeholders and individuals within the Filipino health care and church communities, along with groups that had joint missions to address viral hepatitis. After extensive planning and meetings with faith-based organizations and health care providers in the Filipino community, it was decided to hold a community health fair in the Filipino community to provide culturally appropriate health information and services. More than 500 individuals attended the health fair; 167 participated in a survey and were tested for hepatitis B. Significant knowledge gaps were found in relation to risk factors, prevention strategies, and transmission. Five individuals tested positive; all were immigrants and did not know of their disease. The objective to educate people and test them for hepatitis was successful through utilizing ethnic community leaders, religious organizations, health care professionals, and a collaborative health fair.

Enteropathy-associated T cell lymphoma as a complication of silent celiac disease

Directory of Open Access Journals (Sweden)

Margarida Dantas Brito

2014-12-01

Full Text Available Celiac disease is an autoimmune disorder in which a genetic predisposition and the ingestion of wheat gluten triggers a deleterious immune response. This response is complex and may lead to manifestations other than enteropathyha: hepatitis, dermatitis and neuropathy. There is higher risk for neoplasia. We observed an atypical case, corresponding to a 69-year old female presenting with complicated celiac disease. The patient was referred following the histological examination of an enterectomy specimen, which unexpectedly revealed an enteropathy-associated T cell lymphoma in a background of celiac disease. Patient’s previous medical history comprised several abdominal surgical procedures, without other prior symptoms suggestive of celiac disease. Indeed, the patient was obese and no signs of malabsortion were apparent. This case draws our attention to clinically silent celiac disease, which represents a diagnostic challenge. Thus, this should be kept in mind whenever a patient presents with abdominal relapsing complications, otherwise unexplained.

Structural alterations in rat myocardium induced by chronic l-arginine and l-NAME supplementation

Directory of Open Access Journals (Sweden)

Amal Abdussalam Ali A. Hmaid

2018-03-01

Full Text Available Structural changes affecting cardiomyocyte function may contribute to the pathophysiological remodeling underlying cardiac function impairment. Recent reports have shown that endogenous nitric oxide (NO plays an important role in this process. In order to examine the role of NO in cardiomyocyte remodeling, male rats were acclimated to room temperature (22 ± 1 °C or cold (4 ± 1 °C and treated with 2.25% l-arginine·HCl or 0.01% l-NAME (Nω-nitro-l-arginine methyl ester·HCl for 45 days. Untreated groups served as controls. Right heart ventricles were routinely prepared for light microscopic examination. Stereological estimations of volume densities of cardiomyocytes, surrounding blood vessels and connective tissue, as well as the morphometric measurements of cardiomyocyte diameters were performed. Tissue sections were also analyzed for structural alterations. We observed that both l-arginine and l-NAME supplementation induced cardiomyocyte hypertrophy, regardless of ambient temperature. However, cardiomyocyte hypertrophy was associated with fibrosis and extra collagen deposition only in the l-NAME treated group. Taken together, our results suggest that NO has a modulatory role in right heart ventricle remodeling by coordinating hypertrophy of cardiomyocytes and fibrous tissue preventing cardiac fibrosis.

We aimed to study the impacts of pre-eclampsia on the cognitive and learning capabilities of adolescent rat offspring and to explore the possible underlying mechanisms at the molecular level. Pregnant rats were subcutaneously injected with saline solution (control) (n = 16) or NG-nitro-L-arginine methyl ester (L-NAME) (n = 16) from the 13th day of gestation until parturition. The brain tissues from fetal rats delivered by cesarean section were examined in both groups with hematoxylin and eosin (H&E) staining. Rats born vaginally in both groups were subjected to the Morris water maze test when 8-week-old and their hippocampi were analyzed for glucocorticoid receptor (GR) expression. A pre-eclampsia-like model was successfully built in pregnant rats by infusion of the NO synthase inhibitor L-NAME, including phenotypes as maternal hypertension and proteinuria, high stillbirth rate, and fetal growth retardation. Neuroepithelial cell proliferation was found in the hippocampus of fetal rats in the L-NAME group. Grown to 8-week-old, the L-NAME group showed significantly longer escape latency than the control group in the beginning as well as in the end of navigation trials. At the same time, the swimming distance achieved by the L-NAME group was significantly longer than that of the control group. Such differences in cognitive and learning capabilities between the two groups were not gender dependent. Besides, the 8-week-old rats in the L-NAME group had increased GR expression in the hippocampus than the control group. Pre-eclampsia would impair cognitive and learning capabilities in adolescent offspring, and the upregulated expression of hippocampal GR may be involved in the underlying mechanisms.

Dictionary of Minor Planet Names, Fifth Edition, is the official reference for the field of the IAU, which serves as the internationally recognised authority for assigning designations to celestial bodies and any surface features on them. The accelerating rate of the discovery of minor planets has not only made a new edition of this established compendium necessary but has also significantly altered its scope: this thoroughly revised edition concentrates on the approximately 10,000 minor planets that carry a name. It provides authoritative information about the basis for all names of minor planets. In addition to being of practical value for identification purposes, this collection provides a most interesting historical insight into the work of those astronomers who over two centuries vested their affinities in a rich and colorful variety of ingenious names, from heavenly goddesses to more prosaic constructions. The fifth edition serves as the primary reference, with plans for complementary booklets with newl...

Lexical Access in Persian Normal Speakers: Picture Naming, Verbal Fluency and Spontaneous Speech

Directory of Open Access Journals (Sweden)

Zahra Sadat Ghoreishi

2014-06-01

Full Text Available Objectives: Lexical access is the process by which the basic conceptual, syntactical and morpho-phonological information of words are activated. Most studies of lexical access have focused on picture naming. There is hardly any previous research on other parameters of lexical access such as verbal fluency and analysis of connected speech in Persian normal participants. This study investigates the lexical access performance in normal speakers in different issues such as age, sex and education. Methods: The performance of 120 adult Persian speakers in three tasks including picture naming, verbal fluency and connected speech, was examined using "Persian Lexical Access Assessment Package”. The performance of participants between two gender groups (male/female, three education groups (below 5 years, above 12 years, between 5 and 12 years and three age groups (18-35 years, 36-55 years, 56-75 years were compared. Results: According to findings, picture naming increased with increasing education and decreased with increasing age. The performance of participants in phonological and semantic verbal fluency showed improvement with age and education. No significant difference was seen between males and females in verbal fluency task. In the analysis of connected speech there were no significant differences between different age and education groups and just mean length of utterance in males was significantly higher than females. Discussion: The findings could be a primitive scale for comparison between normal subjects and patients in lexical access tasks, furthermore it could be a horizon for planning of treatment goals in patients with word finding problem according to age, gender and education.

Picture norms for Chinese preschool children: name agreement, familiarity, and visual complexity.

Directory of Open Access Journals (Sweden)

Lamei Wang

Full Text Available Pictorial stimuli standardized for Chinese children are still absent although it is needed in order to test the development of children's cognitive functions. This study presents normative measures for Snodgrass and Vanderwart pictures, viewed by 4- and 6-year old Chinese children. Name agreement, familiarity, and visual complexity were obtained for each age group. The data indicate substantial differences between young and older children in name agreement based on expected name, familiarity and visual complexity. The correlation pattern of the variables collected in the present study were consistent with children's norms in other languages and norms of Chinese adults, while there are cross-age and cross-culture differences in specific variables. The obtained measures represent a useful tool for further research on Chinese children's pictorial processing and constitute the first picture normative study for children in this language.

Noak helynevek és személynevek. [Noak place and personal names

Directory of Open Access Journals (Sweden)

Dénes, György

2013-12-01

Full Text Available In the 13th–14th-century charters, several settlements or lands called Noah ~ Noach ~ Noak are listed from distinct parts of Hungary, of which the most frequently mentioned one, Noak in Gömör county is discussed in the present paper. Analysis of data appearing in charters and localization of relevant place names taken from inspections of landmarks have proved that this settlement was equivalent to (the territory of the present-day village of Imola. Noak as a settlement name has its origin in the biblical personal name Noach, which in the Vulgate is given as Noe. In 11th–12thcentury Hungary, as Christianity was spread mostly by German missionaries, Noah, the original form of the biblical Hebrew name, still in current use in German and English language areas, had become established. As a result of regular Hungarian sound changes, this finally survived as Noak. This form, not recognized by Hungarian priests educated on the basis of the Vulgate, later acquired an intrusive v and changed into Novák. This happened to be identical with the most frequent Hungarian family name of foreign origin, meaning ‘new man’ in the languages of the Slavic ethnic groups then living in the territory of Hungary.

Fast, Inclusive Searches for Geographic Names Using Digraphs

Science.gov (United States)

Donato, David I.

2008-01-01

An algorithm specifies how to quickly identify names that approximately match any specified name when searching a list or database of geographic names. Based on comparisons of the digraphs (ordered letter pairs) contained in geographic names, this algorithmic technique identifies approximately matching names by applying an artificial but useful measure of name similarity. A digraph index enables computer name searches that are carried out using this technique to be fast enough for deployment in a Web application. This technique, which is a member of the class of n-gram algorithms, is related to, but distinct from, the soundex, PHONIX, and metaphone phonetic algorithms. Despite this technique's tendency to return some counterintuitive approximate matches, it is an effective aid for fast, inclusive searches for geographic names when the exact name sought, or its correct spelling, is unknown.

Methods and Materials: A survey of the GHG steering committee members' RTQA procedures, their goals, and naming conventions was conducted. The RTQA procedures were classified as baseline, preaccrual, and prospective/retrospective data capture and analysis. After all the procedures were accumulated and described, extensive discussions took place to come to harmonized RTQA procedures and names. Results: The RTQA procedures implemented within a trial by the GHG steering committee members vary in quantity, timing, name, and compliance criteria. The procedures of each member are based on perceived chances of noncompliance, so that the quality of radiation therapy planning and treatment does not negatively influence the trial measured outcomes. A comparison of these procedures demonstrated similarities among the goals of the various methods, but the naming given to each differed. After thorough discussions, the GHG steering committee members amalgamated the 27 RTQA procedures to 10 harmonized ones with corresponding names: facility questionnaire, beam output audit, benchmark case, dummy run, complex treatment dosimetry check, virtual phantom, individual case review, review of patients' treatment records, and protocol compliance and dosimetry site visit. Conclusions: Harmonized RTQA harmonized naming conventions, which can be used in all future clinical trials involving radiation therapy, have been established. Harmonized procedures will facilitate future intergroup trial collaboration and help to ensure comparable RTQA between international trials, which enables meta-analyses and reduces RTQA workload for intergroup studies.

A Coupled Hidden Conditional Random Field Model for Simultaneous Face Clustering and Naming in Videos

KAUST Repository

Zhang, Yifan

2016-08-18

For face naming in TV series or movies, a typical way is using subtitles/script alignment to get the time stamps of the names, and tagging them to the faces. We study the problem of face naming in videos when subtitles are not available. To this end, we divide the problem into two tasks: face clustering which groups the faces depicting a certain person into a cluster, and name assignment which associates a name to each face. Each task is formulated as a structured prediction problem and modeled by a hidden conditional random field (HCRF) model. We argue that the two tasks are correlated problems whose outputs can provide prior knowledge of the target prediction for each other. The two HCRFs are coupled in a unified graphical model called coupled HCRF where the joint dependence of the cluster labels and face name association is naturally embedded in the correlation between the two HCRFs. We provide an effective algorithm to optimize the two HCRFs iteratively and the performance of the two tasks on real-world data set can be both improved.

Naming game with learning errors in communications

OpenAIRE

Lou, Yang; Chen, Guanrong

2014-01-01

Naming game simulates the process of naming an objective by a population of agents organized in a certain communication network topology. By pair-wise iterative interactions, the population reaches a consensus state asymptotically. In this paper, we study naming game with communication errors during pair-wise conversations, where errors are represented by error rates in a uniform probability distribution. First, a model of naming game with learning errors in communications (NGLE) is proposed....

Reduced verbal fluency for proper names in nondemented patients with Parkinson's disease: a quantitative and qualitative analysis.

Fine, Eric M; Delis, Dean C; Paul, Brianna M; Filoteo, J Vincent

There has been an increasing interest within neuropsychology in comparing verbal fluency for different grammatical classes (e.g., verb generation vs. noun generation) in neurological populations, including Parkinson's disease (PD). However, to our knowledge, few studies have compared verbal fluency for common nouns and proper names in PD. Common nouns and proper names differ in terms of their semantic characteristics, as categories of common nouns are organized hierarchically based on semantics, while categories of proper nouns lack a well-defined semantic organization. In addition, there is accumulating evidence that the retrieval of these distinct grammatical classes are subserved by somewhat distinct neural systems. Given that verbal fluency deficits are among the first impairments to emerge in PD, and that such deficits are predictors of future cognitive decline, it is important to examine all aspects of verbal fluency in this population. For the current study, we compared the performance of a group of 32 nondemented PD patients with 32 healthy participants (HP) on verbal fluency tasks for common nouns (animals) and proper names (boys' first names). A significant interaction between verbal fluency task and diagnostic status emerged, as the PD group performed significantly worse on only the proper name fluency task. This finding may reflect the absence of well-defined semantic organization that structures the verbal search for first names, thus placing a greater onus on strategic or "executive" verbal retrieval processes.

Humorous Names in the Light of Incongruity Theory

Directory of Open Access Journals (Sweden)

Mariusz Rutkowski

2016-07-01

Full Text Available The article addresses the humorous function of proper names in the light of incongruity theory. It aims at proving that, although names are often defined as pragmatically “transparent,” they may possess some humorous value due to semantic and pragmatic shifts resulting from the disturbance of ordinary patterns of proper names identification and interpretation. After a brief introduction, the author discusses different variants of incongruity theory as resented in the works by Victor Raskin and Thomas C. Veatch as well as their possible application to the study of humorous names. The second part of the paper provides an analysis of the humorous effects of proper names which includes anthroponyms, toponyms, trade names, football team names and names in literature. The first section of this part concentrates on names in which humour is unintentional and seems to be induced by the context, while the second section focuses on names which are intentionally humourous, i.e. supposed to amuse from the moment of their creation. The author argues that the incongruity theory can provide a useful framework for the study of the different mechanisms responsible of the semantic shifts which determine the variation of pragmatic values of proper names.

Gorlin-Goltz: what's in a name?

1998-03-01

This paper describes the clinical features of two very distinct syndromes with similar names: Gorlin-Goltz and Goltz-Gorlin Syndromes. A case report is presented that highlights the differences between these syndromes. To avoid errors in diagnosis because of the similarity in names, the authors caution that, based on additional information now available, the preferred names should be Focal Dermal Hypoplasia syndrome for Goltz-Gorlin syndrome and Nevoid Basal Cell Carcinoma syndrome for Gorlin-Goltz syndrome.

Full Text Available  Abstract Pen-name (Takhalloss is one of the main features of Persian poetry. It has been a matter of concern among many of Persian language geography poets in the orient at least up to the Mashrouteh era. Pen-name has been promoted among the other Muslim nations throuph Persian poetry. Although it is not as famous in the Arab nations as in the Persian speaking nations, it is known as “Alqab-o-shoara” among the Arab nations and, through this way, it has affected the poetrical wealth of the Arabic poets.   The Present paper, using description-analystic approach, compares the pen-names of Persian and Arabic poets under the title of “pen-names” and investigates their features in both cultures. The main research question is: What are the similarities and differences of poetic-names, in Persian and Arabic poets in terms of the type of name, position and importance? The results showed that Pseudonym by its amazing expansion in Persian poetry has also influenced Arabic poetry. In addition to the factors affecting in the choice of pen-names (like pseudonym, pen-name, nickname..., sometimes such external factors as events, commends, community benefactors and climate, as well as internal factors including the poets’ inner beliefs are associated too. .

Silent white matter changes (WMCs) on brain imaging are common in individuals with sickle cell disease (SCD) and are associated with cognitive deficits in children. We investigated the factors predictive of WMCs in adults with homozygous SCD and no history of neurological conditions. Patients were recruited from a cohort of adults with homozygous SCD followed up at an adult sickle cell referral center for which steady-state measurements of biological parameters and magnetic resonance imaging scans of the brain were available. WMCs were rated by consensus, on a validated age-related WMC scale. The prevalence of WMCs was 49% (95% confidence interval [CI], 39%-60%) in the 83 patients without vasculopathy included. In univariable analysis, the patients who had WMCs were more likely to be older ( P = .003) and to have hypertension ( P = .02), a lower mean corpuscular volume ( P = .005), a lower corpuscular hemoglobin concentration ( P = .008), and a lower fetal hemoglobin percentage (%HbF) ( P = .003). In multivariable analysis, only a lower %HbF remained associated with the presence of WMCs (odds ratio [OR] per 1% increase in %HbF, 0.84; 95% CI, 0.72-0.97; P = .021). %HbF was also associated with WMC burden ( P for trend = .007). Multivariable ordinal logistic regression showed an inverse relationship between WMC burden (age-related WMC score divided into 4 strata) and HbF level (OR for 1% increase in %HbF, 0.89; 95% CI, 0.79-0.99; P = .039). Our study suggests that HbF may protect against silent WMCs, decreasing the likelihood of WMCs being present and their severity. It may therefore be beneficial to increase HbF levels in patients with WMCs.

Full Text Available Comparative study of cardio protective effect of aliskiren, telmisartan, and torsemide was carried out on l-nitro arginine methyl ester (l-NAME induced hypertension in rats. The three drugs were given daily for 8 weeks simultaneously with l-NAME, with a control group for each drug and l-NAME. The degree of protection was assessed by measurement of systolic blood pressure and heart rate of animals every two weeks. At the end of the experimental period blood sampling was carried out for estimation of the level of NO2−/NO3−. After which animals were sacrificed for heart dissection to detect collagen types I and III gene expression. Histopathological study was done to evaluate the extension of collagen deposits. The study revealed that the three drugs decreased blood pressure significantly compared to l-NAME. There was no significant difference between aliskiren and telmisartan in all measurements, but there was significant decrease in measurements of both aliskiren and telmisartan treated groups compared to torsemide starting from 4th week. There were insignificant changes in pulse rate values between the three l-NAME treated groups through the experiment. The three drugs significantly increased NO compared to l-NAME. Collagen I and III gene expression was significantly decreased by the three drugs but the highest percentage of inhibition was with telmisartan compared to l-NAME. Comparing the percentage inhibition of cardiac fibrosis, there was insignificant difference between telmisartan and torsemide treated groups while both were superior to aliskiren. In conclusion, further experimental studies are required to elucidate the potential cardioprotective mechanisms of aliskiren, telmisartan and torsemide, and assess their efficacy in treatment of heart failure.

Replacing dark energy by silent virialisation

Context. Standard cosmological N-body simulations have background scale factor evolution that is decoupled from non-linear structure formation. Prior to gravitational collapse, kinematical backreaction (𝒬𝒟) justifies this approach in a Newtonian context. Aims: However, the final stages of a gravitational collapse event are sudden; a globally imposed smooth expansion rate forces at least one expanding region to suddenly and instantaneously decelerate in compensation for the virialisation event. This is relativistically unrealistic. A more conservative hypothesis is to allow non-collapsed domains to continue their volume evolution according to the 𝒬𝒟 Zel'dovich approximation (QZA). We aim to study the inferred average expansion under this "silent" virialisation hypothesis. Methods: We set standard (MPGRAFIC) EdS 3-torus (T3) cosmological N-body initial conditions. Using RAMSES, we partitioned the volume into domains and called the DTFE library to estimate the per-domain initial values of the three invariants of the extrinsic curvature tensor that determine the QZA. We integrated the Raychaudhuri equation in each domain using the INHOMOG library, and adopted the stable clustering hypothesis to represent virialisation (VQZA). We spatially averaged to obtain the effective global scale factor. We adopted an early-epoch-normalised EdS reference-model Hubble constant H1EdS = 37.7 km s-1 /Mpc and an effective Hubble constant Heff,0 = 67.7 km s-1 /Mpc. Results: From 2000 simulations at resolution 2563, we find that reaching a unity effective scale factor at 13.8 Gyr (16% above EdS), occurs for an averaging scale of L13.813 = 2.5-0.1+0.1 Mpc/heff. Relativistically interpreted, this corresponds to strong average negative curvature evolution, with the mean (median) curvature functional Ωℛ𝒟 growing from zero to about 1.5-2 by the present. Over 100 realisations, the virialisation fraction and super-EdS expansion correlate strongly at

Packed-bed reactor/silent-discharge plasma design data report

1996-05-01

In 1992, Congress passed the Federal Facility Compliance Act requiring the U.S. Department of Energy (DOE) to treat and dispose of its mixed waste in accordance with Resource Conservation and Recovery Act (RCRA) land disposal restrictions (LDRs). The DOE Albuquerque Operations Office (AL) currently does not have adequate systems to treat the mixed wastes generated and stored at the nine DOE-AL sites. In response to the need for mixed-waste treatment capacity, DOE-AL organized a Treatment Selection Team under the Mixed-Waste Treatment Program (MWTP) to match mixed wastes with treatment options and develop a strategy for treatment of its mixed waste. The strategy developed by the Treatment Selection Team, as described in the AL Mixed-Waste Treatment Plan (DOE 1994), is to use available off-site commercial treatment facilities for all wastes that can be successfully and cost-effectively treated by such facilities. Where no appropriate commercial treatment facilities exist, mobile treatment units (MTUs) would be developed to treat wastes at the sites where the wastes are generated. Treatment processes used for mixed waste must not only address the hazardous component (i.e., meet LDRs) but also must contain the radioactive component in a form that allows final disposal while protecting workers, the public, and the environment. The packed-bed reactor/silent discharge plasma was chosen as a potential candidate for the treatment of the mixed wastes. The process is described

Full Text Available Background and Aim: Rapid automized naming test is an appropriate tool to diagnose learning disability even before teaching reading. This study aimed to detect the cut-off point of this test for good readers and dyslexics.Methods: The test has 4 parts including: objects, colors, numbers and letters. 5 items are repeated on cards randomly for 10 times. Children were asked to name items rapidly. We studied 18 dyslexic students and 18 age-matched good readers between 7 and 8 years of age at second and third grades of elementary school; they were recruited by non-randomize sampling into 2 groups: children with developmental dyslexia from learning disabilities centers with mean age of 100 months, and normal children with mean age of 107 months from general schools in Tehran. Good readers selected from the same class of dyslexics.Results: The area under the receiver operating characteristic curve was 0.849 for letter naming, 0.892 for color naming, 0.971 for number naming, 0.887 for picture naming, and 0.965 totally. The overall sensitivity and specificity was 1 and was 0.79, respectively. The highest sensitivity and specificity were related to number naming (1 and 0.90, respectively.Conclusion: Findings showed that the rapid automized naming test could diagnose good readers from dyslexics appropriately.

This article examines the experiences of nine rape survivors who participated in the Silent Protest, an annual protest march at Rhodes University that aims to highlight the sexual abuse of women, validate the harm done, and foster solidarity among survivors. Participants responded to a semi-structured interview focusing on the context of their rape and its impact, and their experiences of participation in the Protest In the first phase of data analysis, synoptic case narratives were written. In the second, themes from participants' experience were identified using interpretative phenomenological analysis. In the third, the data were examined in light of questions around the extent to which participation contributed to healing. Participants reported experiences of validation and empowerment but the majority were suffering from posttraumatic stress disorder. In some cases, participation had exacerbated self-blame and avoidant coping. Recommendations are made about the provision of psychoeducation and counseling at such events. © The Author(s) 2015.

Robust hybrid name disambiguation framework for large databases

KAUST Repository

Zhu, Jia

2013-10-26

In many databases, science bibliography database for example, name attribute is the most commonly chosen identifier to identify entities. However, names are often ambiguous and not always unique which cause problems in many fields. Name disambiguation is a non-trivial task in data management that aims to properly distinguish different entities which share the same name, particularly for large databases like digital libraries, as only limited information can be used to identify authors\\' name. In digital libraries, ambiguous author names occur due to the existence of multiple authors with the same name or different name variations for the same person. Also known as name disambiguation, most of the previous works to solve this issue often employ hierarchical clustering approaches based on information inside the citation records, e.g. co-authors and publication titles. In this paper, we focus on proposing a robust hybrid name disambiguation framework that is not only applicable for digital libraries but also can be easily extended to other application based on different data sources. We propose a web pages genre identification component to identify the genre of a web page, e.g. whether the page is a personal homepage. In addition, we propose a re-clustering model based on multidimensional scaling that can further improve the performance of name disambiguation. We evaluated our approach on known corpora, and the favorable experiment results indicated that our proposed framework is feasible. © 2013 Akadémiai Kiadó, Budapest, Hungary.

Kurata, C.; Sakata, K.; Taguchi, T.; Kobayashi, A.; Yamazaki, N.

1990-01-01

Factors associated with silent myocardial ischemia (SMI) during exercise testing were studied by means of thallium-201 emission computed tomography (ECT) in 471 patients. Coronary angiography was done in 290, of whom 167 were found to have significant coronary artery disease (CAD). Exercise-induced ischemia and its severity were defined with ECT. During exercise 108 (62%) of 173 patients with ischemia and 57 (50%) of 115 with ischemia and angiographically documented CAD had no chest pain. One third of the patients showed an inconsistency between scintigraphic ischemia and ischemia ST depression. Age, sex, prior myocardial infarction, and diabetes mellitus were not related to SMI. Patients with SMI had less severe ischemia despite a higher peak double product compared to those with painful ischemia. Among 91 with prior myocardial infarction and exercise-induced ischemia, 51 with periinfarction ischemia had a higher frequency of SMI than did 14 with ischemia remote from the prior infarct zone despite similarities in the severity of ischemia. In conclusion, factors localized within ischemic myocardium such as less severe ischemia or adjacency to a prior infarct made SMI more prevalent
