Superficial venous thrombosis of the lower extremities: analysis of risk factors, and recurrence and role of anticoagulation

Superficial venous thrombosis (SVT) of the lower extremities is a common ailment seen in outpatient offices of vascular medicine and surgery practices. This study of 60 consecutive outpatients was carried out to examine the incidence of concomitant deep venous thrombosis (DVT), risk factors associated with SVT, recurrence of SVT and=or new DVT, and the role of anticoagulant therapy in the prevention of recurrence. Concomitant SVT and DVT (13%) were significantly less likely to be present in patients with varicose veins as compared to patients without varicose veins (p < 0.04) and more likely to be present in patients with a previous history of DVT (p < 0.02). Fifteen patients (25%) developed either recurrent SVT or new DVT, with two patients developing both SVT and DVT. The absence of varicose veins and the presence of a hypercoagulable condition (n = 12) appeared to influence the development of new DVT but not the recurrence of SVT. Recurrent SVT was much more likely in patients with thrombosis of the tributaries (p < 0.0008). New DVT was seen significantly less frequently in patients on anticoagulants (p < 0.02).
The spectral reflectivity of the cat's tapetum measured in situ

Gunter, Harding & Stiles (1951) have recently published curves representing the spectral variation of the reflexion factor of the cat's tapetum. Six pairs of tapeta were excised, mounted in glycerine, and their reflexion factor was measured. The maximum reflexion of the incident light amounted to about 25%, and was situated in the blue part of the spectrum. In three cases there were subsidiary maxima in the orange. The authors concluded that the percentage of light reflected was too small to play an appreciable role in modifying the retinal sensitivity. In contradistinction, Granit (1943) ascribed a yellowish green appearance to the light which was reflected maximally from the in situ tapetum and stated that it was a very efficient reflector. Rushton (1952) called its colour green, and Murr (1928) thought that the reflectivity of the tapetum was so considerable and varied so much from cat to cat that this variation would account for the diverging results obtained in his behavioural experiments. It was thought, therefore, that a determination of the in situ reflectivity of the cat's tapetum might perhaps contribute towards the elucidation of some of these problems.
Alternative mechanisms of gene amplification in human cancers

Gene amplification is a common phenomenon in cancer. Cytogenetic analyses have indicated that breakage‐fusion‐bridge (BFB) cycles drive intrachromosomal amplification of some oncogenes in a head‐to‐head manner in human cancers. However, the complex structures of an amplified sequence found in cancers are not always explained by the BFB model. At the 17q21 locus, which is not linked to common fragile sites, we discovered a recombination hot spot harboring amplicon repeats in tandem in a head‐to‐tail orientation, with the interamplicon junctions in each cancer cell being homogeneous. These findings clearly show the presence of alternative mechanisms other than BFB cycles in oncogene amplification. © 2004 Wiley‐Liss, Inc.
Organ damage in HIV-positive patients with high blood pressure.

Our objective has been the investigation of possible cardiovascular or renal organ damage in HIV patients with confirmed high blood pressure by means of instrumental cardiovascular investigation and renal function evaluation. A total of 265 consecutive patients accessing our outpatient facility were enrolled in the study. Patients with confirmed pathological pressure values or high normal values were submitted to clinical and instrumental monitoring by 24-hour ambulatory blood pressure monitoring (ABPM), to derivation of 12-lead ECG registration, to echocardiography and to epi-aortic vessel echo-color-Doppler. The ECG and echocardiographic data were compared to a control group of 40 hypertensive HIV-negative subjects. Renal damage was evaluated by means of the microalbuminuria/creatininuria ratio on a spot urine sample, plus 24-hour albuminuria and proteinuria measurements. 61 (23.0%) of the subjects examined were hypertensive: 24 (39.3%) had a previous hypertensive diagnosis but had never been treated for this condition, and 37 (60.7%) had a new diagnosis; In 100% of cases, 24-hour ABPM confirmed the hypertension and 27.8% of the patients resulted non-dippers. The ECG showed left ventricle overload, V4-V6 strain, or left ventricular hypertrophy in 64.3% of cases compared to 35.7% in the control group. Echocardiography demonstrated increasing in left ventricle parietal thickness with concentric remodeling and hypertrophy in 85.2% of patients. HIV-positive patients showed a statistically significant tendency to concentric remodeling and concentric hypertrophy, even in presence of mild hypertension. Echocolor-Doppler examination detected intima-media thickness > and/or carotid plaques in 72.1% of patients. Renal function seems spared in these subjects. Our data highlights the importance of investigating arterial hypertension among our patients as it is a frequently undiagnosed condition, and illustrates the utility of 24- hr ABPM to confirm hypertension and to identify the non-dipper subject. Moreover, the ECG, echocardiography and echocolor-Doppler examinations evidenced a premature tendency to organ damage in these patients that showed altered cardiac remodeling compared to those without HIV. This stresses the need for an early diagnosis, including a complete instrumental evaluation to properly identify organ damage even at a subclinical level.
Tritium and Deuterium Content of Atmospheric Hydrogen

The tritium and deuterium content of 24 samples of atmospheric hydrogen collected at ground level near Buffalo. N.Y. (U.S.A.). Hamburg (Germany), and Nürnberg (Germany) during 1954 to 1956 was measured. At the beginning of 1954 the T/H-ratio was found to have been 9.18 · 10-14 i.e. about a factor of 10 higher than 1949 (FALTINGS and HARTECK) and 1951 (v. GROSSE et al.), probably due to the first explosion of a thermonuclear device in November 1952. In spite of a major test series of thermonuclear weapons in spring of 1954 (Operation CASTLE) no further increase in the tritium content was found during 1954 and 1955. It shows instead a seasonal variation with low tritium content in summer and about a threefold higher one in winter. Simultaneously, there is a good correlation between the tritium and deuterium concentrations. From 1956 on a noticeable increase in the tritium content due to more man-made HT produced or released by thermonuclear devices into the atmosphere was found, in agreement with measurements by GONSIOR. A possible explanation of the experimental results as well as a mode to test the validity of the model suggested is given. The deuterium concentrations of the samples analysed vary between about +7 percent and –17 percent, compared to Standard Lake Michigan Water with a ratio D/H = 0.0148 ± 0.0002 mol percent. Although from these results only a correlation factor between the tritium and deuterium content of “mean atmospheric hydrogen” and not their absolute values can be derived it is obvious that atmospheric hydrogen and the water vapour of the atmosphere are not in thermodynamic equilibrium, as has been pointed out before by HARTECK and SUESS.
Enamel color changes following orthodontic treatment

Objective: To evaluate and compare the effect of various orthodontic bonding systems and clean up procedures on quantitative enamel colour change. Materials and Methods: A literature search was done to identify the studies that assessed the quantitative enamel colour change associated with the various bonding systems and cleanup procedures. Electronic database (Pub Med, Cochrane and Google Scholar) were searched. First stage screening was performed and the abstracts were selected according to the initial selection criteria. Full text articles were retrieved and analyzed during second stage screening. The bibliographies were reviewed to identify additional relevant studies. Results: Sixteen full text articles were retrieved. Six were rejected because the methodology was different. There was significant enamel colour change following orthodontic bonding, debonding and clean up procedures. Conclusion: Self–etching primers produce less enamel colour change compared to conventional etching. Resin Modified GIC produces least colour change compared to other light cure and chemical cure systems. Polishing following the clean-up procedure reduces the colour change of the enamel.
Improving load forecasting based on deep learning and K-shape clustering

One of the most crucial tasks for utility companies is load forecasting in order to plan future demand for generation capacity and infrastructure. Improving load forecasting accuracy over a short period is a challenging open problem due to the variety of factors that influence the load, and the volume of data that needs to be considered. This paper proposes a new approach for short term load forecasting using an effective new combination of clustering and deep learning methods, along with a new weighted aggregation mechanism. Our evaluation using smart meter data from a publicly available real-life dataset demonstrates the improved accuracy of our approach over existing methods.
Long-range experimental modification of values, attitudes, and behavior.

1. Contemporary social psychologists generally agree that a necessary prerequisite to cognitive or attitude change is the presence of a state of imbalance or inconsistency. Two major experimental methods generally employed to create such a psychological state are (a) to induce a person to engage in behavior that is incompatible with his attitudes and values and (b) to expose him to information about the attitudes or values of significant others that are incompatible with his own attitudes and values. In contrast to these two well-known methods, we have employed a third method, namely, to expose a person to information designed to make him consciously aware of states of inconsistency that exist chronically within his own value-attitude system below the level of his conscious awareness. 2. While the main theoretical focus of contemporary social psychology is on the concept of attitude and on theories of attitude change, the present focus is on the concept of value and on a theory of value change. This shift from attitudes to values is made on the assumption that values are more fundamental components within a person's makeup than attitudes and, moreover, that values are de-
The decline and fall of seasonality in the Australian stock exchange, 1958-2005

This paper examines calendar effects in Australian daily stock returns over the forty-seven years from 6 January 1958 to 30 December 2005. Three principal calendar effects – day-of-the-week, day-of-the-month and month-ofthe-year – are examined separately and jointly using parametric tests of differences in means and variances and a regression-based approach. The results indicate that the Australian market is characterised by seasonality of all three forms, with Tuesday, December and the second day of the month among the most significant. However, there is also evidence of structural change in these relationships, with indications that the market has become more efficient in recent years, with day-of-the-week and day-of-the-month effects becoming less important in the post-1987 crash period.

Seroprevalence of Neospora caninum in Sheep and Goats from Grenada, West Indies

Neospora caninum (N. caninum), an intracellular protozoan parasite, causes abortion and neonatal mortality in many herbivores including sheep and goats. The aim of this study was to estimate the Seroprevalence of N. caninum in sheep and goats in Grenada, West Indies. Sera were collected from 138 sheep and 138 goats from all six parishes of Grenada and Carriacou, a small island within Grenada. Animals were identified by gender. Sera were tested for antibodies for N. caninum using an indirect Enzyme Linked Immunosorbant Assay (ELISA) multispecies Kit from Pourquire Laboratorie (IDvet, France). Antibodies to N. caninum were detected in 18 of 138 sheep (13%, 95% confidence interval (CI): 7.39% to 18.61%) and 8 of 138 goats (5.8%, 95% CI: 1.9% to 9.7%). Although seropositivity was high in female sheep and in male goats, there was no statistical difference in seropositivity of males and females in both species of animals (p > 0.05, χ2). The results of this study revealed that sheep and goats in Grenada were exposed to N. caninum and dogs might be considered as a source of infection. There was a need to educate the farmers, possessing small ruminants, about the transmission cycle of N. caninum and methods of prevention, to minimize the exposure of their flocks. This is the first report on seroprevalence of N. caninum in Grenada, West Indies.
All for one but does one strategy work for all

Purpose – The purpose of this paper is to explore how multichannel customers evaluate overall satisfaction across distribution channels and what the antecedents are of such satisfaction.Design/methodology/approach – A survey of bank customers in Taiwan was conducted. The total number of valid questionnaires was 479. Reliability and validity were tested. Maximum likelihood procedure of LISREL 8.8 was used to test the hypothesized structural equation model.Findings – The findings indicate that the overall satisfaction in the multichannel environment is a critical determinant of customer retention and participation. The present study also develops the antecedents of multichannel satisfaction. In the multichannel environment, perceived multichannel service quality is positively related to satisfaction, while perceived channel switching difficulty is negatively related to satisfaction.Originality/value – The present study employs the stimulus‐organism‐response (S‐O‐R) paradigm and the channel loyalty framework.
Dietary modulation of intestinal fructose transport and GLUT5 mRNA expression in hypothyroid rat pups.

BACKGROUND Intestinal fructose transport rates or GLUT5 mRNA levels typically show a two- to threefold increase after weaning in rats allowed to wean normally but can be enhanced precociously by high-fructose diets during early weaning. Developmental increases in serum thyroxine levels coincide with the onset of weaning and have been linked to changes in intestinal sucrase and lactase activities. METHODS Rat pups were made hypothyroid by giving the dam 0.01% propylthiouracil as drinking water from day 18 of gestation. The hypothyroid pups and age-matched euthyroid control pups were then fed high-fructose or high-glucose solutions by gavage, twice a day starting at 17 days of age for 3 days, and then killed at 20 days of age. RESULTS Serum thyroxine levels were five times lower in the hypothyroid pups. Rates of intestinal fructose uptake in the proximal and middle small intestine were 2.0 to 2.5 times higher in the hypothyroid and euthyroid pups fed high-fructose solution than in littermates fed high-glucose solution or those allowed to wean normally with the dam. Intestinal glucose uptake also increased in hypothyroid but not in euthyroid pups fed high-fructose or high-glucose solutions. GLUT5 mRNA levels increased in euthyroid and hypothyroid pups fed high fructose and paralleled the increase in fructose uptake. CONCLUSION During weaning, dietary fructose can precociously enhance intestinal fructose uptake and GLUT5 mRNA expression, independent of developmental increases in serum thyroxine levels. Modest changes in glucose transport rates indicate that nonspecific mechanisms may provide a minor contribution to diet-induced changes in nutrient absorption in hypothyroid pups.
Prospective study of cytomegalovirus antigenemia in allograft recipients

A recently published technique for direct detection of cytomegalovirus (CMV) antigenemia was tested prospectively in 27 transplant recipients. Eighteen patients developed active CMV infections and 10 of the 18 experienced CMV syndrome. All of the infections were detected by classical virus isolation and/or serologic techniques. No antigenemia was demonstrated.
A Cross‐cultural Study of Moral Philosophies, Ethical Perceptions and Judgements: A Comparison of American and Thai Marketers

Moral philosophers and marketing ethicists generally agree that variations in moral judgements exist between different cultures. Compares American marketers with Thai marketers with respect to their moral philoso‐phies, ethical perceptions, and ethical judgements. The results based on a survey of members of the American Marketing Association and the Thai Marketing Association indicate that American marketers are both less idealistic and less relativistic than Thai marketers. In addition, the survey results reveal that American marketers differ from Thai marketers with respect to their perceptions of ethical problems, and ethical judgements.

Basal Cell Carcinomas of the Eyelids

Basal cell carcinomas (BCC) are the more frequent malignant tumors seen in France as in other western countries. They represent 20% of eyelid tumors and 90% of eyelid malignancies. Due to their local growth, problems may arise when treating BCC, and curative exeresis must be the preferred choice each time it is possible. BCC of the eyelids have a high risk of recurrence. Recurrences are more aggressive, infiltrative and destructive and have a considerably poorer rate of cure than primary tumors. Eyelid reconstructions can entail use of complex methods which should only be carried out by a trained ophthalmologist who is also able to treat any associated age-related ocular pathologies. BCC is the most common cause leading to eyelid reconstructive surgery; a surgery which has a triple objective: tumor removal, functionality and an esthetic outcome.
Modification of Akt1 by methylglyoxal promotes the proliferation of vascular smooth muscle cells

Methylglyoxal (MG), a reactive dicar‐bonyl molecule, can modify protein to form advanced glycation endproducts. Increased MG level has been implicated in proliferative vascular diseases, but the underlying mechanisms are not clear yet. The serine/ threonine kinase, Akt, regulates multiple signaling pathways that control cell proliferation. Using mass spectrometric analysis, we have detected the modification of Akt1 by MG at Cys77. This structural modification increased Akt1 phosphorylation at Ser473 and Thr308. Akt1 phosphorylation and activity were also increased by MG treatment (<50 µM) in cultured vascular smooth muscle cells (VSMCs). MG treatment of VSMCs led to increased DNA synthesis (EC50=5.8 µM), cell proliferation, phosphorylation of p21 and glycogen synthase kinase‐3α/β (GSK‐3α/β), and increased cyclin‐dependent kinase 2 (CDK2) activity. These effects of MG were significantly inhibited by silencing Akt1 or by an Akt inhibitor. Overexpression of Akt1 Cys77Ser mutant in HEK‐293 cells increased cell proliferation and DNA synthesis, concurrent with an increase in Akt1 activity, which could not be further augmented by MG treatment. It is concluded that MG‐induced VSMC proliferation is mediated by the activation of Akt1 via the modification of Akt1 at Cys77. —Chang, T. , Wang, R. , Olson, D. J. H. , Mousseau, D. D. , Ross, A. R.

The role of credit in post-stabilization consumption booms

This paper presents an empirical investigation of the role of credit in the post-stabilization consumption booms of Mexico, Chile, and Israel. Credit from the banking sector to the private sector expanded very rapidly following the stabilizations. I show that this increase in credit reduced the proportion of consumers that were liquidity constrained in the economy. This reduction in liquidity constraints could have helped to fuel the observed consumption booms. In addition, I show that the most important channels for the expansion in credit to consumers in Mexico are the rapid remonetization of the economy, the fall in the ratio of debt held by banks to GDP held by banks, and the increase in the foreign liabilities of banks. For Chile, the most important channel is the remonetization of the economy, whereas in Israel, it is the crowding in effect from the fall in the ratio of public debt held by banks to GDP. The fact that only the crowding in effect was important for Israel, is explained by the differences between its banking system and those of the other countries.
THE MODIFICATION OF DIGITALIS INTOXICATION BY EXCLUDING ADRENERGIC INFLUENCES ON THE HEART.

We have studied the modifications of digitalis intoxication caused by the following procedures: (a) neserpinization, (b) surgical removal of the thoracic sympathetic chains and the adnenals, (c) administration of the beta adnenergic blocking agent, nethalide. While all the control dogs intoxicated with cardiac glycosides die by ventricular fibrillation, most of the treated animals die in cardiac arrest. The ventricle remains excitable and propagates impulses after arrest. The ventricular arrhythmias that precede digitalis fibrillation are absent in some of the treated animals. At the same time the lethal dose of the glycosides is elevated. These changes are more likely to occur when digitoxin rather than ouabain is used. The alpha adrenergic blocking agent, phenoxybenzamine, does not modify digitalis intoxication. We ascribe the modifications of digitalis intoxication to a reduction in adnenergic influences on the heart.
Cepstral Statistics Compensation and Normalization Using Online Pseudo Stereo Codebooks for Robust Speech Recognition in Additive Noise Environments

This paper proposes several cepstral statistics compensation and normalization algorithms which alleviate the effect of additive noise on cepstral features for speech recognition. The algorithms are simple yet efficient noise reduction techniques that use online-constructed pseudo-stereo codebooks to evaluate the statistics in both clean and noisy environments. The process yields transformations for both clean speech cepstra and noise-corrupted speech cepstra, or for noise-corrupted speech cepstra only, so that the statistics of the transformed speech cepstra are similar for both environments. Experimental results show that these codebook-based algorithms can provide significant performance gains compared to results obtained by using conventional utterance-based normalization approaches. The proposed codebook-based cesptral mean and variance normalization (C-CMVN), linear least squares (LLS) and quadratic least squares (QLS) outperform utterance-based CMVN (U-CMVN) by 26.03%, 22.72% and 27.48%, respectively, in relative word error rate reduction for experiments conducted on Test Set A of the Aurora-2 digit database.
