Distortion-product otoacoustic emissions (DPOAEs) arise in the cochlea in response to two tones with frequencies f1 and f2 and mainly consist of two components, a nonlinear-distortion and a coherent-reflection component. Wave interference between these components limits the accuracy of DPOAEs when evaluating the function of the cochlea with conventional continuous stimulus tones. Here, DPOAE components are separated in the time domain from DPOAE signals elicited with short stimulus pulses. The extracted nonlinear-distortion components are used to derive estimated distortion-product thresholds (EDPTs) from semi-logarithmic input-output (I/O) functions for 20 normal-hearing and 21 hearing-impaired subjects...

A neuron is categorized as "multisensory" if there is a statistically significant difference between the response evoked, e.g., by a crossmodal stimulus combination and that evoked by the most effective of its components separately. Being responsive to multiple sensory modalities does not guarantee that a neuron has actually engaged in integrating its multiple sensory inputs: it could simply respond to the stimulus component eliciting the strongest response in a given trial. Crossmodal enhancement is commonly expressed as a proportion of the strongest mean unisensory response...

Halloysite is a natural nanotubular clay mineral (HNTs, Halloysite Nano Tubes) chemically identical to kaolinite and, due to its good biocompatibility, is an attractive nanomaterial for a vast range of biological applications. Chitosan oligosaccharides are homo- or heterooligomers of N-acetylglucosamine and D-glucosamine, that accelerate wound healing by enhancing the functions of inflammatory and repairing cells. The aim of the work was the development of a nanocomposite based on HNTs and chitosan oligosaccharides, to be used as pour powder to enhance healing in the treatment of chronic wounds...

BACKGROUND: Up to 40% of abdominal aortic aneurysms (AAAs) have coexistent iliac artery aneurysms (IAAs). In the past, successful endovascular repair required internal iliac artery (IIA) embolization, which can lead to pelvic or buttock ischemia. This study describes a technique that uses a readily available solution with a minimally altered off-the-shelf bifurcated graft in the IAA to maintain IIA perfusion. METHODS: From August 2009 to May 2015, 14 patients with AAAs and coexisting IAAs underwent repair with a bifurcated-bifurcated approach...

BACKGROUND: Despite a multitude of evidence-based prediction models and risk factors for postoperative complications after ventral hernia repair, estimating a patient's risk of postoperative complications after ventral hernia repair remains challenging. In an attempt to improve the preoperative assessment of complex hernia patients, some studies have examined pulmonary changes after hernia repair hypothesizing that large hernias lead to pulmonary changes and increased pulmonary complication rates...

An open posterior component separation (PCS) is a commonly utilized surgical approach for repair of complex abdominal wall defects and hernias. Although this approach may improve surgical outcomes, significant postoperative pain can be expected given the required laparotomy and extensive abdominal wall manipulation. Both systemic opioids and thoracic epidural analgesia (TEA) are viable postoperative analgesic options, and both are commonly utilized. Although the benefits of TEA have been investigated following a variety of surgeries, there is a paucity of literature related to its efficacy for this particular surgery...

A moisturizing cream mixed with a steroid ointment is frequently prescribed to patients suffering from atopic dermatitis. However, there is a concern that the mixing operation causes destabilization. The present study was performed to investigate the stability of such preparations closely using magnetic resonance imaging (MRI). As sample preparations, five commercial moisturizing creams that are popular in Japan were mixed with an ointment base, a white petrolatum, at a volume ratio of 1 : 1. The mixed preparations were stored at 60°C to accelerate the destabilization processes...

The composition of skeletal muscle was investigated in the quadriceps and gastrocnemius muscle of 13-month-old (n=15) and 23-month-old (n=19) mice by means of high-resolution nuclear magnetic resonance (NMR) spectroscopy. Muscle specimens were dissected out, frozen in liquid nitrogen and extracted in chloroform/methanol, and proton NMR spectra of the resulting aqueous and organic fractions were obtained at 600MHz. Several metabolites were unambiguously identified and quantified. Multivariate ANOVA (factor: age, muscle, age×muscle) showed a significant main effect of age (P=0...

BACKGROUND: Ventral hernia represents a surgical challenge plagued by high morbidity and recurrence rates. Primary closure of challenging hernias is often prohibited by severe lateral retraction and tension of the abdominal wall musculature. Botulinum toxin injections have recently been identified as a potential pre-operative means to counteract abdominal wall tension, reduce hernia size, and facilitate fascial closure during hernia repair. This systematic review and meta-analysis reviews outcomes associated with botulinum toxin injections in the setting of ventral hernia, and demonstrates an opportunity to leverage this mainstream aesthetic product for use in abdominal wall reconstruction...

We propose a simple yet effective structural patch decomposition (SPD) approach for multi-exposure image fusion (MEF) that is robust to ghosting effect. We decompose an image patch into three conceptually independent components: signal strength, signal structure, and mean intensity. Upon fusing these three components separately, we reconstruct a desired patch and place it back into the fused image. This novel patch decomposition approach benefits MEF in many aspects. First, as opposed to most pixel-wise MEF methods, the proposed algorithm does not require post-processing steps to improve visual quality or to reduce spatial artifacts...
