Image and Tourist Discourses: Turkey Seen by Advertisements

Our work is proposing an analysis of the tourist image of Turkey through advertisements introducing the country. We assume that the “tourist space” is an image created together by the advertising executives, the travel agencies and the tourist himself. Indeed, the advertising executives' just as much as public and private actors try to meet the tourists request for authenticity. Accordingly, they emphasize certain points of interests and interpret them according to supposed tourists' expectations. This approach has for results to reduce the “tourist space” to a mere element of folklore, of orientalism and of exoticism, and even more to propose stereotypical images. As such this constructed image of the tourist advertising may refer to a specific communication contract between the advertising executive and its target. Since the advertising executives have for main purpose to establish a coherency between travelers' expectations and the existing reality the iconic images choice proposed in the “tourist speech” exposes to a social construction of the reality.
Wide-Angle Low-Loss 1×2 Multimode Interference Optical Power Divider with Tilted Input and Output Waveguides

Multimode interference (MMI) coupler with tilted input/output waveguides is proposed. By the self-imaging theory of MMI couplers, the output fields at the end of the multimode region have tilted phase fronts and automatically propagate toward the branching waveguides. The waveguides with layered structure and vertical sidewalls are used to simulate the proposed device. The excess loss is only 0.24 dB even though the branch angle is 20 degrees.
SUBTHALAMIC NUCLEUS DEEP BRAIN STIMULATION

OBJECTIVE: To prospectively assess the impact of subthalamic nucleus (STN) deep brain stimulation (DBS) at 12 months after surgery in a series of 100 consecutive patients treated in a single center. The primary objective was to describe the clinical outcome in terms of efficacy and tolerance in STN-DBS patients. A secondary objective was to discuss presurgery clinical characteristics a posteriori as a function of outcome. METHODS: One hundred and three consecutive patients with severe Parkinson’s disease received bilateral STN-DBS in our clinic between May 1998 and March 2003. Clinical assessment was performed before and 12 months after surgery and was based on the Unified Parkinson’s Disease Rating Scale, Parts II, III, and IV A; the Schwab and England Scale; and cognitive evaluation. Patient-rated overall improvement was also evaluated. RESULTS: Twelve months after surgery, the Unified Parkinson’s Disease Rating Scale Part III score decreased by 43%, the Unified Parkinson’s Disease Rating Scale Part II score (activities of daily living) fell by 34%, and the severity of dyskinesia-related disability decreased by 61%. The main surgical complications after STN-DBS were as follows: infection (n 7), intracerebral hematoma (n 5), electrode fracture (n 4), and incorrect lead placement (n 8). We observed cognitive decline and depression in 7.7 and 18% of the patients, respectively. The mean patient-rated overall improvement score was 70.7%. CONCLUSION: The efficacy and safety of STN-DBS in our center’s large cohort of Parkinsonian patients are generally similar to the results obtained by other groups, albeit at the lower limit of the range of reported values. In contrast to efficacy, the occurrence of adverse events cannot be predicted. Younger patients with Parkinson’s disease (i.e., those younger than 60 yr) often show an excellent response to levodopa. However, in view of our data on overall patient satisfaction and the occurrence of adverse events, we suggest that older patients (but not those older than 70 yr) and less dopa-sensitive patients (but not those with a response 50%) should still be offered the option of STN-DBS.
Low-dose hydrocortisone improves shock reversal and reduces cytokine levels in early hyperdynamic septic shock*

Objectives:To investigate the effect of low-dose hydrocortisone on time to shock reversal, the cytokine profile, and its relation to adrenal function in patients with early septic shock. Design:Prospective, randomized, double-blind, single-center study. Setting:Medical intensive care unit of a university hospital. Patients:Forty-one consecutive patients with early hyperdynamic septic shock. Interventions:After inclusion and a short adrenocorticotropic hormone test, all patients were randomized to receive either low-dose hydrocortisone (50-mg bolus followed by a continuous infusion of 0.18 mg/kg body of weight/hr) or matching placebo. After shock reversal, the dose was reduced to 0.06 mg/kg/hr and afterward slowly tapered. Severity of illness was estimated using Acute Physiology and Chronic Health Evaluation II score and Sequential Organ Failure Assessment score. Measurements and Main Results:Time to cessation of vasopressor support (primary end point) was significantly shorter in hydrocortisone-treated patients compared with placebo (53 hrs vs. 120 hrs, p < .02). This effect was more profound in patients with impaired adrenal reserve. Irrespective of endogenous steroid production, cytokine production was reduced in the treatment group with lower plasma levels of interleukin-6 and a diminished ex vivo lipopolysaccharide-stimulated interleukin-1 and interleukin-6 production. Interleukin-10 levels were unaltered. Adverse events were not more frequent in the treatment group. Conclusions:Treatment with low-dose hydrocortisone accelerates shock reversal in early hyperdynamic septic shock. This was accompanied by reduced production of proinflammatory cytokines, suggesting both hemodynamic and immunomodulatory effects of steroid treatment. Hemodynamic improvement seemed to be related to endogenous cortisol levels, whereas immune effects appeared to be independent of adrenal reserve.
Characterisation of the gastrointestinal mucosa‐associated microbiota: a novel technique to prevent cross‐contamination during endoscopic procedures

The mucosa‐associated microbiota appears to be highly relevant to host–microbe interactions in the gastrointestinal (GI) tract. Thus, precise characterisation of the mucosa‐associated microbiota may provide important insights for diagnostic and therapeutic development. However, for technical reasons, mucosal biopsies taken during standard endoscopic procedures are potentially contaminated by GI luminal contents.
Vascular structure and expression of endothelin-1 gene in L-NAME-treated spontaneously hypertensive rats.

Inhibition of nitric oxide synthase by L-arginine analogues is associated with elevation of blood pressure in rats. Deoxycorticosterone acetate (DOCA)-salt hypertensive rats and DOCA-salt-treated spontaneously hypertensive rats (SHR) overexpress the endothelin-1 gene in blood vessels, and this is associated with severe vascular hypertrophy, whereas SHR do not overexpress endothelin-1 and exhibit limited vascular hypertrophy. In this study malignant hypertension was induced in SHR by chronic administration of the L-arginine analogue NG-nitro-L-arginine methyl ester (L-NAME), a potent inhibitor of nitric oxide synthase, to determine whether malignant hypertension would result in endothelin-1 gene overexpression in blood vessels and in greater severity of vascular hypertrophy, as found in malignant DOCA-salt-treated SHR. L-NAME treatment induced malignant hypertension in SHR, with a systolic blood pressure of 246 +/- 2 mm Hg, compared with 211 +/- 2 mm Hg (P < .01) in untreated SHR. Plasma renin activity was very high in L-NAME-treated SHR, and their plasma immunoreactive endothelin concentration was slightly but significantly elevated (P < .01). After 3 weeks of treatment, aortic and to a lesser degree mesenteric artery weights were significantly increased in L-NAME-treated SHR compared with untreated SHR. However, cardiac weight and the media cross-sectional area or media width-to-lumen diameter ratio of small arteries from the coronary, renal, mesenteric, or femoral vasculature were not increased in L-NAME-treated SHR in comparison with untreated SHR. The abundance of endothelin-1 mRNA measured by Northern blot analysis was significantly increased in L-NAME-treated SHR in aorta and with less magnitude in the mesenteric arterial tree. The absence of accentuation of cardiac and small artery hypertrophy in malignant hypertension in L-NAME-treated SHR, despite enhanced expression of the endothelin-1 gene in blood vessels, may suggest a direct or indirect inhibitory effect of L-NAME on cardiovascular growth, probably independent of its effects on nitric oxide synthase, counterbalanced in aorta and large mesenteric arteries by the hypertrophic effect of enhanced vascular endothelin-1 gene expression. These results also suggest a role for blood pressure and potentially for nitric oxide in the regulation of endothelin-1 gene expression in blood vessels.
Secretion of N- and O-linked Glycoproteins from 4T1 Murine Mammary Carcinoma Cells

Breast cancer is one of the most common cancers that affect women globally and accounts for ~23% of all cancers diagnosed in women. Breast cancer is also one of the leading causes of death primarily due to late stage diagnoses and a lack of effective treatments. Therefore, discovering protein expression biomarkers is mandatory for early detection and thus, critical for successful therapy. Two-dimensional electrophoresis (2D-E) coupled with lectin-based analysis followed by mass spectrometry were applied to identify potential biomarkers in the secretions of a murine mammary carcinoma cell line. Comparisons of the protein profiles of the murine 4T1 mammary carcinoma cell line and a normal murine MM3MG mammary cell line indicated that cadherin-1 (CDH), collagenase 3 (MMP-13), Viral envelope protein G7e (VEP), Gag protein (GAG) and Hypothetical protein LOC433182 (LOC) were uniquely expressed by the 4T1 cells, and pigment epithelium-derived factor (PEDF) was exclusively secreted by the MM3MG cells. Further analysis by a lectin-based study revealed that aberrant O-glycosylated CDH, N-glycosylated MMP-13 and LOC were present in the 4T1 medium. These differentially expressed N- and O-linked glycoprotein candidates, which were identified by combining lectin-based analysis with 2D-E, could serve as potential diagnostic and prognostic markers for breast cancer.
Improved Linearity Active Resistor Using Equivalent FGMOS Devices

An original active resistor circuit was presented in this paper. The main advantages of the new proposed implementations are the improved linearity, the small area consumption and the improved frequency response. An original technique for linearizing the I(V) characteristic of the active resistor was proposed, based on a parallel connection of two quasi-identical circuits opposite excited and different polarized having the result of improving the circuit linearity with about an order of magnitude. The errors introduced by the second-order effects were also strongly reduced, while the advantage of using FGMOS devices is achieved maintaining the compatibility with classical technologies. The frequency response of the circuit is very good as a result of operating all MOS transistors in the saturation region. The circuit is implemented in 0.35mum CMOS technology, the SPICE simulation confirming the theoretical estimated results and showing a linearity error under a percent for an extended input range (plusmn500mV) and a small value of the supply voltage (plusmn3V)
Prediction of Gene Function in Methylthioadenosine Recycling from Regulatory Signals

ABSTRACT The S-box transcription termination control system, first identified in Bacillus subtilis, is used for regulation of gene expression in response to methionine availability. The presence of the S-box motif provided the first indication that the ykrTS and ykrWXYZ genes could play a role in recycling of 5′-methylthioadenosine, a by-product of polyamine biosynthesis that can be converted to methionine. In this study we demonstrate a role for the ykrTS and ykrWXYZ gene products in this pathway.
Organic acids and their salts as dipping solutions to control listeria monocytogenes inoculated following processing of sliced pork bologna stored at 4 degrees C in vacuum packages.

Postprocessing contamination of cured meats with Listeria monocytogenes has become a major concern for the meat processing industry and an important food safety issue. This study evaluated aqueous dipping solutions of organic acids (2.5 or 5% lactic or acetic acid) or salts (2.5 or 5% sodium acetate or sodium diacetate, 5 or 10% sodium lactate, 5% potassium sorbate or potassium benzoate) to control L. monocytogenes on sliced, vacuum-packaged bologna stored at 4 degrees C for up to 120 days. Organic acids and salts were applied by immersing (1 min) in each solution inoculated (10(2) to 10(3) CFU/cm2) slices of bologna before vacuum packaging. Growth of L. monocytogenes (PALCAM agar) on inoculated bologna slices without treatment exceeded 7 log CFU/cm2 (P < 0.05) at 20 days of storage. No significant (P > 0.05) increase in L. monocytogenes populations occurred on bologna slices treated with 2.5 or 5% acetic acid, 5% sodium diacetate, or 5% potassium benzoate from day 0 to 120. Products treated with 5% potassium sorbate and 5% lactic acid were stored for 50 and 90 days, respectively, before a significant (P < 0.05) increase in L. monocytogenes occurred. All other treatments permitted growth of the pathogen at earlier days of storage, with sodium lactate (5 or 10%) permitting growth within 20 to 35 days. Extent of bacterial growth on trypticase soy agar plus 0.6% yeast extract (TSAYE) was similar to that on PALCAM, indicating that the major part of total bacteria grown on TSAYE agar plates incubated at 30 degrees C was L. monocytogenes. Further studies are needed to evaluate organic acids and salts as dipping solutions at abusive temperatures of retail storage, to optimize their concentrations in terms of product sensory quality, and to evaluate their effects against various other types of microorganisms and on product shelf life. In addition, technologies for the commercial application of postprocessing antimicrobial solutions in meat plants need to be developed.
Determinants of the Eurosystem's Central Banks Provisions

Central bank provisions may be used as a measure of the perceived risk of the balance sheet composition by a central bank. We identify three possible sources that may change the size of the provisions. These are: The length of the balance sheet, the central bank revenues, and measures of fiscal stress. Using data of the 11 founding members of the Eurosystem for the years 1999–2015, we are able to test each of the three determinants. We find that provisions are increased with the size of the balance sheet especially in the recent financial crisis. Moreover, provisions are increased at the cost of lower central bank revenues. While this holds for the pre‐crisis period this relationship seems to be less pronounced in the crisis period probably because of the more active collateral policy. Finally, central banks do not tend to lower provisions because of fiscal tensions. This is even more true in the crisis period.
Experimental validation of hyperthermia SAR treatment planning using MR B1+ imaging

In this paper the concept of using B1+ imaging as a means to validate SAR models for radiofrequency hyperthermia is presented. As in radiofrequency hyperthermia, in common clinical MR imaging which applies RF frequencies between 64 and 128 MHz, the RF field distribution inside a patient is largely determined by the dielectric distribution of the anatomy. Modern MR imaging techniques allow measurement of the RF magnetic field component B1+ making it possible to measure at high resolution the dielectric interaction of the RF field with the patient. Given these considerations, we propose to use MR imaging to verify the validity of our dielectric patient model used for SAR models of radiofrequency hyperthermia. The aim of this study was to investigate the feasibility of this concept by performing B1+ measurements and simulations on cylindrical split phantoms consisting of materials with dielectric properties similar to human tissue types. Important topics of investigation were the accuracy and sensitivity of B1+ measurements and the validity of the electric model of the MR body coil. The measurements were performed on a clinical 1.5 T MR scanner with its quadrature body coil operating at 64 MHz. It was shown that even small B1+ variations of 2 to 5% could be measured reliably in the phantom experiments. An electrical model of the transmit coil was implemented on our FDTD-based hyperthermia treatment planning platform and the RF field distributions were calculated assuming an idealized quadrature current distribution in the coil. A quantitatively good correlation between measurements and simulations was found for phantoms consisting of water and oil, while highly conductive phantoms show considerable deviations. However, assuming linear excitation for these conductive phantoms resulted in good correspondence. As an explanation it is suggested that the coil is being detuned due to the inductive nature of the conductive phantoms, breaking up the phase difference of π/2 between the two quadrature modes. It is concluded that B1+ imaging is an accurate and sensitive method for obtaining quantitative information about the RF field in phantoms. The electrical model of the body coil is inadequate for highly conductive phantoms. It is expected that for experiments on human bodies the inductive coupling is also significant, demonstrating the need for a full resonant FDTD model of the transmit coil. This will be pursued in the near future.
Revisiting gender differences in ultimatum bargaining: experimental evidence from the US and China

We report results from a replication of Solnick (Econ Inq 39(2):189, 2001), which finds using an ultimatum game that, in relation to males, more is demanded from female proposers and less is offered to female responders. We conduct Solnick’s (2001) game using participants from a large US university and a large Chinese university. We find little evidence of gender differences across proposer and responder decisions in both locations.
Review: Neutrophil gelatinase‐associated lipocalin: A troponin‐like biomarker for human acute kidney injury

Acute kidney injury (AKI) is a common and serious condition, the diagnosis of which currently depends on functional markers such as serum creatinine measurements. Unfortunately, creatinine is a delayed and unreliable indicator of AKI. The lack of early biomarkers of structural kidney injury (akin to troponin in acute myocardial injury) has hampered our ability to translate promising experimental therapies to human AKI. Fortunately, understanding the early stress response of the kidney to acute injuries has revealed a number of potential biomarkers. The discovery, translation and validation of neutrophil gelatinase‐associated lipocalin (NGAL), possibly the most promising novel AKI biomarker, is reviewed. NGAL is emerging as an excellent stand‐alone troponin‐like structural biomarker in the plasma and urine for the early diagnosis of AKI, and for the prediction of clinical outcomes such as dialysis requirement and mortality in several common clinical scenarios. The approach of using NGAL as a trigger to initiate and monitor therapies for AKI, and as a safety biomarker when using potentially nephrotoxic agents, is also promising. In addition, it is hoped that the use of sensitive and specific biomarkers such as NGAL as endpoints in clinical trials will result in a reduction in required sample sizes, and hence the cost incurred. Furthermore, predictive biomarkers like NGAL may play a critical role in expediting the drug development process. However, given the complexity of AKI, additional biomarkers (perhaps a panel of plasma and urinary biomarkers) may eventually need to be developed and validated for optimal progress to occur.
Accounting for Busines Cycles in Canada: II. The Role of Money

I have explained business cycles in Canada focusing on the role of money. To do that, I have used both empirical and theoretical models. The empirical investigations include performing causality tests and computing impulse responses based on structural and co-integrated vector autoregressive models. The theoretical models consist of RBC and new-Keynesian models. Some of these theoretical models are: the inflation tax, the inflation and tax code, the sticky price, and the financial accelerator models. The empirical models indicate monetary disturbances are instrumental in business cycle fluctuations but do not necessarily cause them. The theoretical models also point out that monetary disturbances contribute to business cycle fluctuations but not as much as technological change. Some channels through which they propagate are: nominal capital gain tax, price stickiness, and deteriorating financial conditions. Price stickiness turns out to play a major r
Regulation of asparagine synthetase gene transcription by the basic region leucine zipper transcription factors ATF5 and CHOP

Abstract Asparagine synthetase catalyses the glutamine- and ATP-dependent conversion of aspartic acid to asparagine. In human hepatoma cells cultured in mediumcontaining amino acids, the mRNA of asparagine synthetase is not detectable by RNase protection mapping. However, maintaining the cells in amino acid-free Krebs-Ringer bicarbonate buffer strongly upregulated asparagine synthetase biosynthesis. The effect of amino acid deprivation on asparagine synthetase gene transcription is mediated by a genetic element termed the nutrient-sensing response unit. Previous studies revealed that the basic region leucine zipper (bZIP) transcription factor CREB2/ATF4 is involved in the nutrient deprivation-induced upregulation of asparagine synthetase gene transcription. Here we show that overexpression of the bZIP protein ATF5, a transcriptional activator, stimulates asparagine synthetase promoter/reporter gene transcription via the nutrient-sensing response unit. In contrast, ATF5 does not transactivate cAMP response element (CRE)-containing reporter genes. Overexpression of the C/EBP homologous transcription factor CHOP impaired transcriptional activation of the asparagine synthetase promoter following amino acid deprivation or over-expression of ATF5 or CREB2/ATF4. These data indicate that CHOP functions as a shut-off-device for nutrient deprivation-induced gene transcription.
Engineering the variable region of therapeutic IgG antibodies

Since the first generation of humanized IgG1 antibodies reached the market in the late 1990s, IgG antibody molecules have been extensively engineered. The success of antibody therapeutics has introduced severe competition in developing novel therapeutic monoclonal antibodies, especially for promising or clinically validated targets. Such competition has led researchers to generate so-called second or third generation antibodies with clinical differentiation utilizing various engineering and optimization technologies. Parent IgG antibodies can be engineered to have improved antigen binding properties, effector functions, pharmacokinetics, pharmaceutical properties and safety issues. Although the primary role of the antibody variable region is to bind to the antigen, it is also the main source of antibody diversity and its sequence affects various properties important for developing antibody therapeutics. Here we review recent research activity in variable region engineering to generate superior antibody therapeutics.
