Cardiac metabolism remains altered for an extended period of time after myocardial infarction. Studies have shown fibroblasts from normal hearts express KATP channels in culture. It is unknown whether fibroblasts from infarcted hearts express KATP channels and whether these channels contribute to scar and border zone electrophysiology. KATP channel subunit expression levels were determined in f...
Introduction The incidence of foreign bodies (FBs) in the rectum has recently increased. FB removal by the transanal way or by colonoscopy is generally feasible and only in few cases surgery is strictly necessary. Due to FB dimensions or rectum and colon anatomy, sometimes it may represent a challenge. Materials and Methods Two cases of FB inserted in the rectum were treated in our institute....
The mechanism of H migration in amorphous Si has remained an unresolved problem. The main issue is the small activation energy (1.5 eV) relative to the known strength of Si-H bonds (2-3.5 eV). We report first-principles finite-temperature simulations which demonstrate vividly that H is not released spontaneously, as proposed by most models, but awaits the arrival of a floating bond (FB). The "m...
We give an upper bound to the finite block length capacity of discrete time nonstationary Gaussian channel with delayed feedback. With the aid of minimization of a quadratic form, it is proved that the L time delayed feedback capacity C n,FB(P ) and the nonfeedback capacity Cn(P ) satisfy Cn(P ) ≤ C n,FB(P ) ≤ Cn(P∗), where P∗ is concretely given. And we give a sufficient condition for C n,FB(P...
A foreign body (FB) in the upper aerodigestive tract is a common clinical problem that presents as as acute emergency. Sharp FB, such as fish bone or chicken bone, commonly lodges in the tonsil, base of tongue, vallecula or pyriform fossa. Dislodgement of a FB into the laryngopharynx is very rare and specifically onto the vocal cord is extremely uncommon. This case report illustrates a rare cas...
Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at √ s = 8 TeV Abstract A measurement of the forward–backward asymmetry A FB of oppositely charged lepton pairs (μμ and ee) produced via Z/γ * boson exchange in pp collisions at √ s = 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.7 fb −1 collected with the CMS detector at the LHC. The measu...

Follicular bronchiolitis (FB) is a rare small-airway pathology that is associated mainly with connective tissue diseases. This case report presents a new, diagnosed, different airway disease in a non-smoker with rheumatoid arthritis in remission who was treated for presumed asthma, but was not controlled. She was ultimately diagnosed with FB after video-assisted thoracoscopic surgery. The clini...
Foreign body (FB) ingestion is a common clinical problem. The majority of s�allo�ed object are often passed spontaneously �ithout complications. Ho�ever, a small proportion of FB that passes from the stomach result in complication distally �hich require a surgery. We describe an ileal perforation follo�ing the ingestion of a duck bone �hich �as diagnosed by CT preoperatively and confirmed by la...
Inhaled foreign body (FB) is one of the most problematic conditions, especially in childhood. Rapid and safe bronchoscopy removal of inhaled foreign bodies is the treatment of choice in these cases. Spontaneous expulsion of inhaled FB bronchus is rarely mentioned in the literature. We present three cases of expelled foreign bodies of which two were coughed out, and the third one went into the g...
