Background: Anti-allergic drugs, such as tranilast and ketotifen, inhibit the release of chemokines from mast cells. However, we know little about their direct effects on exocytotic process Since exocytosis in cells can be monitored electrophysiologically by changes whole-cell membrane capacitance (Cm), absence these drugs indicates cell-stabilizing properties. Methods: Employing standard patch-clamp recording technique rat peritoneal cells, examined ketotifen Cm during exocytosis. Using...

In Brief BACKGROUND: The effects of fentanyl with ketamine for postoperative pain are unknown. We investigated the adjuvant patient-controlled analgesia. METHODS: Cervical and lumbar spine surgery patients were divided into three groups: 1 mg/kg followed by 42 83 μg · kg−1 h−1 in ketamine-1 ketamine-2 group, respectively, a control group. Postoperative analgesia was administered background infusion. RESULTS: Pain scores requirement group significantly lower than those after cervical surgery....

Intraoperative motor-evoked potential (MEP) monitoring reduces postoperative motor deficits. Propofol-based total intravenous anesthesia is the gold standard for intraoperative myogenic MEPs. Although there no contraindication to administering propofol in adults with peanut, soy, or egg allergies, its safety children these allergies remains unclear.A 12-year-old girl required general under direct cortical MEP (dc-MEP) due supratentorial glioma. Remimazolam-based was selected, instead of...

Abstract Background Esophagectomy is a high-risk procedure that can involve serious postoperative complications. There has been an increase in the number of minimally invasive esophagectomies (MIEs) being performed. However, relationship between intraoperative management and complications MIE remains unclear. Methods After institutional review board approval, we enrolled 300 patients who underwent at Tohoku University Hospital April 2016 March 2021. The relationships among patient...

Abstract Purpose Passive leg raising (PLR) increases intrathoracic blood volume by redistributing from the lower to upper body area. While inspiratory effort is hypothesized have a similar effect due pressure differences between and extrathoracic cavities, direct evidence scarce. Therefore, this study evaluated whether excessive using end-expiratory lung impedance (EELI). Methods Volunteers, fitted with electrical tomography (EIT) belts, underwent spontaneous breathing procedure in supine...

Podoplanin (PDPN/Aggrus/T1α/gp36/OTS-8), a type I transmembrane sialoglycoprotein, is involved in platelet aggregation, cell invasion, and cancer metastasis. expression cells or cancer-associated fibroblasts was reported to be poor prognosis of several cancers. Furthermore, podoplanin expressed lymphatic endothelial lung alveolar cells. Although many anti-podoplanin monoclonal antibodies (MAbs), such as NZ-1 D2–40, have been established, almost all MAbs are produced against...

Circulating endothelial microparticles (EMPs) are considered to be markers of injury, and lung microvascular cells express higher levels angiotensin-converting enzyme (ACE). The aim this study is examine whether the number ACE + EMPs could a prognostic marker for development acute respiratory distress syndrome (ARDS) in septic patients. numbers culture supernatant from human cells, as well blood mouse injury models patients (n=82), were examined using flow cytometry. pulmonary increased...

Background/Aims: Adrenaline quickly inhibits the release of histamine from mast cells. Besides β2-adrenergic receptors, several in vitro studies also indicate involvement α-adrenergic receptors process exocytosis. Since exocytosis cells can be detected electrophysiologically by changes membrane capacitance (Cm), its continuous monitoring presence drugs would determine their cell-stabilizing properties. Methods: Employing whole-cell patch-clamp technique rat peritoneal cells, we examined...

Thoracic epidural anesthesia (TEA) and paravertebral block (PVB) have been performed for perioperative regional in the trunk. However, TEA PVB are associated with a risk of serious complications, such as pneumothorax, hypotension, or nerve damage. Retrolaminar (RLB) was introduced new alternative to PVB. This approach might lower but its use has not well established yet. Therefore, we conducted double-masked, placebo-controlled, randomized clinical trial evaluate efficacy double-level RLB...
