Oxygen transport in the mixed ionic-electronic conducting perovskite-oxides SrTi1-yFeyO3-δ (with y = 0.5 and y = 1.0) was studied by oxygen isotope exchange measurements. Experiments were performed on thin-film samples that were grown by Pulsed Laser Deposition (PLD) on MgO substrates. Isotope penetration profiles were introduced by (18)O2/(16)O2 exchanges into the plane of the films at various temperatures in the range 773 < T/K < 973 at an oxygen activity aO2 = 0.5. Isotope profiles were determined subsequently by Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), and their analysis yielded tracer diffusion coefficients D* and oxygen surface exchange coefficients k*...

An efficient and selective procedure for the synthesis of epiminodibenzo[b,f][1,5]diazocines involving a AB2 three-component reaction is developed. Two equivalents of suitably substituted 2-aminoarylaldehydes reacted with arylamines in the presence of Yb(OTf)3 to afford the desired products in high yields. The reaction is highly atom-economic and waste-free, in addition to allowing the generation of two heterocyclic rings and four C-N bonds in a single operation. Significantly, this approach is complementary to the existing literature procedures, affording arylamine-derived products that could not be accessed previously...

Acquired bilateral facial palsy is rare and causes difficulty with speech and eating, but dynamic reanimation of the face can reduce the effect of these problems. Of 712 patients who had these procedures during our study period, two had an acquired bilateral facial paralysis. In both, reanimation was completed in a single operation using a free-functional transfer of the latissimus dorsi muscle that was coapted to the masseteric branch of the trigeminal nerve. Both patients achieved excellent non-spontaneous excursion and an improvement in function...

BACKGROUND: Left atrial appendage occlusion (LAAO) is mostly performed by transesophageal echocardiography (TEE) guidance. Intracardiac echocardiography (ICE) may be an alternative imaging modality for LAAO that precludes the need for general anesthesia or sedation. METHODS AND RESULTS: All consecutive single center, single operator LAAO candidates were analyzed. Baseline clinical and procedural characteristics and in-hospital outcomes were compared between patients in whom a Watchman was implanted with ICE vs...

BACKGROUND: The T-piece resuscitator (TPR) is in common use worldwide to deliver positive pressure ventilation during resuscitation of infants <10 kg. Ease of use, ability to provide positive end-expiratory pressure (PEEP), availability of devices inbuilt into resuscitaires and cheaper disposable options have increased its popularity as a first-line device for term infant resuscitation. Research into its ventilation performance is limited to preterm infant and animal studies. Efficacy of providing PEEP and the use of TPR during term infant resuscitation are not established...

INTRODUCTION: Vulvodynia is a common and debilitating disease, for which treatments are often of limits efficacy. As the Impar node receives nociceptive afferents from pelvis and perineum, it is a potential therapeutic target to treat pain in this region. The objective of the study was to evaluate the relevance of ropivacaine Impar node infiltration in patients suffering from rebel vulvodyny. METHODS: This was a retrospective, single-center study. The Impar node infiltrations were performed by a single operator in eight patients suffering from rebel vulvodynia...

BACKGROUND: Decompressive craniectomy procedures are performed in patients with malignant intracranial hypertension. A bone flap is removed to relieve pressure. Later a second operation is performed to reconstruct the skull after brain swelling has resolved. This surgical treatment would be improved if it were possible to perform a single operation that decompressed the brain acutely while eliminating the need for a second operation. In order to design a device and procedure that achieves this objective it is essential to understand how the brain swells following a craniectomy procedure...
