BACKGROUND Non-ventilator ICU-acquired pneumonia after cardiothoracic surgery is challenging to diagnose, and little is known about its impact on patient outcomes. Here, our primary objective was to compare the sensitivity and specificity of cultures of 2 types of fiberoptic bronchoscopy (FOB) specimens: endotracheal aspirates (FOB-EA) and bronchoalveolar lavage fluid (FOB-BAL). The secondary o...

Studies of patterned spontaneous activity can elucidate how the organization of neural circuits emerges. Using in vivo two-photon Ca(2+) imaging, we studied spatio-temporal patterns of spontaneous activity in the optic tectum of Xenopus tadpoles. We found rhythmic patterns of global synchronous spontaneous activity between neurons, which depends on visual experience and developmental stage. By ...

efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted inrecent years. however, many basic questions have been ambiguous up until now. nanoparticlespenetrate into pore volume of porous media, stick on the core surface, and by creating homogeneouswater-wet area, cause to alter wettability. this work introduces the new concept of adding znonanoparticle...

splenic rupture during pregnancy is considered a catastrophic condition associated with high maternal and fetal mortality and morbidity. herein, we report a case of severe preeclampsia that underwent cesarean delivery with subsequent spontaneous splenic rupture. a 21-year-old primigravid woman was transferred to our center due to severe preeclampsia that underwent cesarean delivery because of u...

background vegf gene has been reported to be related with many diseases and recurrent pregnancy loss in various studies. vegf polymorphisms are risk factors for pregnancy losses, and generally studies report only women’s genetic analyses. to evaluate the association between vegf a c405g, c460t, c936t and c2578a polymorphisms and spontaneous abortion, we studied the genotypes of spontaneously ab...

introduction  mechanical ventilation may be lifesaving intervention,it can be associated with complications,thus,successful weaning is constitutive.one of the factors which is  important in successful weaning is  method of weaning. it is shown that  weaning is conducted successfully by using spontaneous breathing trial (sbt) through t-piece and pressure support (ps) ventilation.but few studies ...

background severe birth asphyxia (apgar < 7 at the 5th minute of birth) is recognized as a hearing loss risk factor by the joint committee on infant hearing (jcih). about half of the newborns with hearing loss do not indicate any sign and risk factor at birth. accordingly, the joint committee recommended performance of hearing screening test in 2000, especially for babies born with risk factors...

The structures of molecules form the cornerstone of our chemical knowledge. Lowering of symmetry in closed-shell molecules is often attributed to the Pseudo Jahn-Teller (PJT) distortions wherein non-adiabatic coupling (NAC) between the ground state and excited states creates vibrational instability along specific normal modes. Nevertheless, other factors like steric interactions are also well k...

Why Sentence Modality in Spontaneous Speech is More Diicult to Classify and why this Fact is not too bad for Prosody \You crazy," said Max. It was either a statement or a question. \So you're our man, then," he said. It was half statement, half question. ABSTRACT We show in this paper that the labeling of sentence modality in German, esp. of questions vs. non-questions, is more diicult for spon...

Previous studies suggest that there may be a distinct relationship between spontaneous neural activity and subsequent or concurrent self-specific stimulus-induced activity. This study aims to test the impact of spontaneous activity as recorded in an eyes-open (EO) resting state as opposed to eyes-closed (EC) on self-specific versus non-self-specific auditory stimulus-induced activity in fMRI. I...
