Patients undergoing cochlear implantation could benefit from a simultaneous application of drugs into the ear, helping preserve residual low-frequency hearing and afferent nerve fiber populations. One way to apply drugs is to incorporate a cannula into the implant, through which drug solution is driven. For such an approach, perilymph concentrations achieved and the distribution in the ear over time have not previously been documented. We used FITC-labeled dextran as a marker, delivering it into perilymph of guinea pigs at 10 or 100 nL/min though a cannula incorporated into a cochlear implant with the outlet in the mid basal turn...

BACKGROUND: Anastomotic leakage is a determining factor of morbidity and mortality after an esophagectomy. An adequate blood supply of the gastric conduit is vital to prevent this complication. We aimed to determine the feasibility and usefulness of indocyanine green (ICG) fluorescence imaging to evaluate the gastric conduit perfusion during an esophagectomy. METHODS: Patients with distal esophageal cancer or esophagogastric junction cancer scheduled for esophagectomy were enrolled in this study...

AIMS: The present study was designed to explore the neuroprotective potential of inorganic nitrite as a new therapeutic avenue in Parkinson's disease (PD). RESULTS: Administration of inorganic nitrite ameliorates neuropathology in phylogenetically distinct animal models of PD. Beneficial effects are not confined to prophylactic treatment and occur also if nitrite is administered when the pathogenic cascade is already active. Mechanistically, the effect is mediated by both complex I S-nitrosation, which under nitrite administration is favored over formation of other forms of oxidation, and as well as down-stream activation of the antioxidant Nrf2 pathway...

Spontaneous rupture is a life-threatening complication of hepatocellular carcinoma (HCC). Detecting active bleeding is critical. Color Doppler and contrast-enhanced ultrasonography (CEUS) with Levovist(®) are reported to be useful for detecting active bleeding. A few reports have described using Sonazoid(®) to detect bleeding in ruptured HCC. This report describes two distinctive patterns of bleeding from ruptured HCC observed in CEUS with Sonazoid(®). Four patients with suspected HCC rupture were examined by gray-scale ultrasonography (US) and then CEUS with Sonazoid(®)...

BACKGROUND: Patients with upper third esophageal cancer or esophageal cancer with upper mediastinal paratracheal lymph node metastases are often precluded from surgery because of technical difficulties. With the aid of robotic surgery, an excellent overview and reach of the thoracic inlet can be accomplished. In this way, patients with upper mediastinal esophageal cancer are eligible for esophageal resection with curative intent. The aim of this study was to review the results of a consecutive series of patients who underwent robot-assisted minimally invasive esophagectomy (RAMIE) for tumors of the upper 1/3 of the esophagus or positive lymph nodes in the upper mediastinum...

Rationale and key points This article discusses post-discharge care for patients following stoma formation. While the patient is taught the practicalities of managing the stoma appliance in hospital, this learning should be integrated into their daily life following discharge from hospital. Nurses are required to consider and address any issues that might affect the patient in the long term. These include changes in body image, adapting to having a stoma, preventing or treating complications associated with a stoma, and long-term follow-up...

Methane (CH4) is emerging as a candidate of signal molecule recently. However, whether or how CH4 enhances plant adaptation to aluminum (Al)-contaminated environment is still unknown. In this report, the physiological roles and possible molecular mechanisms of CH4 in the modulation of Al toxicity in alfalfa seedlings were characterized. Our results showed that, CH4 pretreatment could alleviate Al-induced seedling growth inhibition and redox imbalance. The defensive effects of CH4 against Al toxicity including the remission of Al-induced root elongation inhibition, nutrient disorder, and relative electrolyte leakage...

INTRODUCTION AND HYPOTHESIS: The pelvic floor muscles (PFM) play an important part in the urinary continence mechanism. Changes in their structure and functionality may lead to a predisposition to pelvic floor dysfunction such as urinary incontinence (UI), which is the involuntary loss of urine. Some techniques for conservative treatment of UI are already well documented. However, new approaches have been found that require scientific proof of their effectiveness, such as vibratory stimulation (VS)...

The concept that flavonoids exert cardioprotection against myocardial ischemia-reperfusion (I/R) injury has been acknowledged by a large body of evidence. However, recent studies reported cardiotoxic effects of certain flavonoids, while the underlying mechanisms have remained largely elusive. Flavonoids have been demonstrated to activate aryl hydrocarbon receptor (Ahr), which is implicated in an array of cell signaling processes. The present study examined the cardioprotective roles of quercetin (Qu) and β-naphthoflavone (β-NF) against I/R injury and explored whether the underlying mechanism proceeds via molecular signaling downstream of Ahr...
