AIM OF THE STUDY In many countries, Low Level Disinfection (LLD) of covered transvaginal ultrasound probes is recommended between patients' examinations. The aim of this study was to evaluate the antimicrobial efficacy of LLD under routine conditions on a range of microorganisms. MATERIALS AND METHODS Samples were taken over a six month period in a private French Radiology Center. 300 specime...

background: measuring of maternal serum pregnancy-associated plasma protein-a (papp-a) in first trimester can be a way for early detection of adverse prenatal outcome due to faulty placenta.objective: the aim was to determination of association between placental thickness in second trimester with low level of papp-a in first trimester.materials and methods: in this cohort study, serum papp-a of...

The term ‘emergence’ often causes confusion in science and philosophy, as it is used to express at least two quite different concepts. We can label these concepts strong emergence and weak emergence. Both of these concepts are important, but it is vital to keep them separate. We can say that a high-level phenomenon is strongly emergent with respect to a low-level domain when the high-level phen...

Low intensity pulsed ultrasound is used in the clinical treatment of fractures and other osseous defects. Level I clinical studies demonstrate the ability of a specific ultrasound signal (1.5 MHz ultrasound pulsed at 1 kHz, 20% duty cycle, 30 mW/cm(2) intensity (SATA)) to accelerate the healing time in fresh tibia, radius and scaphoid fractures by up to 40%. Additionally, the same ultrasound si...

Scripting languages are great for gluing together components, but they suffer as the complexity or size of data scales upward. Data objects solve this problem by marrying both high-level and low-level programming styles. Data objects are self-contained representations of data. They define both the structure of the data and the methods to access it. Data may be accessed through both Tcl and a C ...

The present study investigated enhancement of apoptosis induction and the mechanisms underlying calcium overload on C6 glioma cells in vitro, stimulated by low-level ultrasound in combination with hematoporphyrin monomethyl ether (HMME). The optimum frequency of ultrasound was determined by 3-(4,5-dimethythiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The apoptotic rate, reactive oxygen sp...

We show a learning-based method for low-level vision problems{estimating scenes from images. We generate a synthetic world of scenes and their corresponding rendered images. We model that world with a Markov network, learning the network parameters from the examples. Bayesian belief propagation allows us to e ciently nd a local maximum of the posterior probability for the scene, given the image...

Background: The accurate differentiation of perinatal torsioned ovarian cysts (PTOCs) in neonates is of utmost importance. This importance is due to the fact that if PTOCs are diagnosed properly, minimally invasive or conservative management approaches can be offered. The present study aimed to describe the ultrasound findings of PTOCs and compare the results with pathological findings.Me...
