Enhancement of antitumor activity of the oxazaphosphorine cytostatic SUM-IAP by N -methylformamide

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 4 δευτερόλεπτα
Abstract Purpose SUM-IAP has been developed with the aim to optimize therapeutic response and minimize toxic reactions of oxazaphosphorine cytostatics. In therapy tests in mice, the primary tumor was successfully eradicated, but animals died due to formation of lethal metastases. We supposed that high activities of SUM-IAP detoxifying enzymes caused metastasis formation in the liver. Therefore, therapy tests with SUM-IAP in combination with cisplatin and *N*-methylformamide (NMF), which were not detoxified in the liver, were carried out. Method Antitumor activity was assayed in f... περισσότερα »

Enhanced electromagnetic field in the tiny gaps between metallic nanostructures holds great promise in optical applications. Herein, we report novel out-of-plane nanogaps composed of micrometer-sized Ag triangular nanoplates (AgTN) on Ag films. Notably, the new coupled plasmonic structure can dramatically enhance the surface-enhanced Raman scattering (SERS) by visible laser excitation, although the micrometer-sized AgTN has localized plasmon resonance at infrared wavelength. This enhancement is derived from the gap plasmon polariton between the AgTN and Ag film, which is excited v... περισσότερα »

[image: nanoaa1856f1_lr.jpg] In this work, we develop a 2D algorithm for stochastic reaction–diffusion systems describing the binding and unbinding of target molecules at the surfaces of affinity-based sensors. In particular, we simulate the detection of DNA oligomers using silicon-nanowire field-effect biosensors. Since these devices are uniform along the nanowire, two dimensions are sufficient to capture the kinetic effects features. The model combines a stochastic ordinary differential equation for the binding and unbinding of target molecules as well as a diffusion equation for... περισσότερα »

Effects of a consistent target or masker voice on target speech intelligibility in two- and three-talker mixtures

Alexandros G. SfakianakisστοOtoRhinoLaryngology - Alexandros G. SfakianakisΠριν από 27 δευτερόλεπτα
Effects of a consistent target or masker voice on target speech intelligibility in two- and three-talker mixtures: When the spatial location or identity of a sound is held constant, it is not masked as effectively by competing sounds. This suggests that experience with a particular voice over time might facilitate perceptual organization in multitalker environments. The current study examines whether listeners benefit from experience with a voice only when it is the target, or also when it is a masker, using diotic presentation and a closed-set task (coordinate response measure).

Musician advantage for speech-on-speech perception: Evidence for transfer of musical training to better perception of speech in noise has been mixed. Unlike speech-in-noise, speech-on-speech perception utilizes many of the skills that musical training improves, such as better pitch perception and stream segregation, as well as use of higher-level auditory cognitive functions, such as attention. Indeed, despite the few non-musicians who performed as well as musicians, on a group level, there was a strong musician benefit for speech perception in a speech masker.

Relativistic triple differential cross-sections (TDCS) for ionization of hydrogen atoms by positron impact have been calculated in the symmetric coplanar geometry. We have used Dirac wave functions to describe free electron's and positron's sates. The relativistic formalism is examined by taking the non relativistic limit. Present results are compared with those for the corresponding electron-impact case. In the first Born approximation, we found that the TDCS for positron impact ionization exceeds that for electron impact for all energies in accordance with the result obtained by... περισσότερα »

A miniaturized fiber-optic colorimetric sensor for nitrite determination by coupling with a microfluidic capillary waveguide

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 1 ώρα
Abstract A microfluidic-capillary-waveguide-coupled fiber-optic sensor was developed for colorimetric determination of hazardous nitrite based on the Griess–Ilosvay reaction. The sensor was modularly designed by use of a light-emitting diode as the light source, silica fiber as the light transmission element, and a capillary waveguide tube as the light reaction flow cell. With the light interacting with the azo dye generated by the Griess–Ilosvay reaction between nitrite and Griess reagents, nitrite could be determined by a colorimetric method according to Beer's law. By use of th... περισσότερα »

A GOP-level fuzzy rate control algorithm for high-delay applications of HEVC

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 1 ώρα
Abstract The high -efficiency video coding (HEVC) standard was introduced for high-resolution video contents suitable for many high-delay applications. The bit rate of compressed video is controlled in almost all digital video applications according to the practical constraints such as available channel bandwidth and allowed delay or buffering constraint. In high-delay video applications such as video broadcasting and video streaming applications, variable-bit-rate videos can provide a higher visual quality than constant-bit-rate videos. In this paper, a rate control algorithm (RC... περισσότερα »

High veno-arterial carbon dioxide gradient is not predictive of worst outcome after an elective cardiac surgery: a retrospective cohort study

Alexandros G. SfakianakisστοΒιοΜηχανικήΠριν από 1 ώρα
Abstract Alteration of tissue perfusion is a main contributor of organ dysfunction. In cardiac surgery, the importance of organ dysfunction is associated with worse outcome. Central venous-arterial difference in CO2 tension (ΔCO2) has been proposed as a global marker of the adequacy of tissue perfusion in shock states. We hypothesized that ΔCO2 could be increased in case of postoperative organ failure or worse outcome. In this monocentric retrospective cohort study, we retrieved, from our database, 220 consecutive patients admitted in intensive care after an elective cardiac surge... περισσότερα »

Objective: Transfusion-related acute lung injury is the leading cause of transfusion-related mortality. Preclinical studies have shown that aged RBCs can induce transfusion-related acute lung injury in the presence of a «first hit» (e.g., sepsis). Clinical studies, however, show conflicting results on this matter. We tested whether maximally stored RBCs are able to induce lung injury… Continue reading Transfusion of 35-Day Stored RBCs in the Presence of Endotoxemia Does Not Result in Lung Injury in Humans.
