Role of PPARα in inflammatory response of C2C12 myotubes.

Recent studies have shown a role of inflammation in muscle atrophy and sarcopenia. However, no anti-inflammatory pharmacotherapy has been established for the treatment of sarcopenia. Here, we investigate the potential role of PPARα and its ligands on inflammatory response and PGC-1α gene expression in LPS-treated C2C12 myotubes.

Adrenal Cushing syndrome in a patient with corticosteroid-treated asthma and worsening diabetes mellitus.

A 55-year-old woman with poor diabetic control and a long history of corticosteroid-treated asthma was admitted. Hypertension and dyslipidaemia developed 9 and 6 years ago, respectively, and both were poorly controlled. Three years ago, her asthma control improved, and oral/intravenous steroids were switched to inhalers.

Perioperative management of patients with cancer pain treated with opioids: a retrospective study.

Purpose: We retrospectively studied perioperative management of patients receiving opioid treatment for cancer pain to facilitate establishing a standard policy for our institute.

Methods: Subjects were patients who had been administered strong opioids for cancer pain and had undergone surgery with general anesthesia. We divided the patients into groups C and D.

[A Case of Psychogenic Tremor during Awake Craniotomy].

A 31-year-old woman with a left frontal and parietal brain tumor underwent awake craniotomy. Propofol/remifentanil general anesthesia was induced. Following craniotomy, anesthetic administrations ceased.

[Two cases of medicinal treatment of diabetic post treatment painful neuropathy].

Painful diabetic neuropathy is a common, difficult-to-manage complication of diabetes. We report two case of intractable painful diabetic neuropathy which occurred after the rapid lowering of blood sugar level. Although pregabalin, antidepressants, opioid analgetics and various nerve block did not improve their pain, clomipramine dramatically reduced their pain.

Difference in the effects of tandospirone on ataxia in various types of spinocerebellar degeneration: an open-label study.

The aim of this study was to investigate the effects of tandospirone on ataxia in various types of spinocerebellar degeneration (SCD). Fifteen milligram per day of tandospirone was administered to 39 patients with SCD (spinocerebellar atrophy (SCA) 1, five patients; SCA2, six patients; Machado-Joseph disease (MJD), 14 patient; SCA6, five patients; multiple system atrophy-cerebellar type (MSA-C), seven patients; and multiple system atrophy-Parkinson type (MSA-P), two patients). All patients were assessed before and 4 weeks after administration of the drug using the international cooperative ataxia rating scale total score (ARS), total length traveled (TLT) of body stabilometry, and a self-rating depression scale.

[Perioperative management of a patient with deep vein thrombosis caused by estrogen producing granulosa cell tumor of the ovary].

We experienced perioperative management of a woman with large thrombi in femoral veins caused by estrogen producing ovarian tumor. At presentation, serum estradiol level was extremely high. Time constraint due to rapid expansion of the tumor did not allow us a trial of preoperative anti-coagulation.

Airway scope and StyletScope for tracheal intubation in a simulated difficult airway.

Background: Direct laryngoscopy is difficult when the cervical spine is immobilized. The Airway Scope and StyletScope are new laryngoscopes designed to facilitate intubation under these circumstances. Thus, in patients wearing a rigid cervical collar to simulate a difficult airway, we tested the hypothesis that the intubation success rates of the Airway Scope and StyletScope are similar, but that intubation with Airway Scope is faster.

Role of IRS and PHIP on insulin-induced tyrosine phosphorylation and distribution of IRS proteins.

To analyze the functional differences of the insulin receptor substrate (IRS) family, the N-terminal fragments containing the pleckstrin homology (PH) domains and the phosphotyrosine-binding (PTB) domains of IRS (IRS-N) proteins, as well as intact IRS molecules, were expressed in Cos-1 cells, and insulin-induced tyrosine phosphorylation and subcellular distribution of IRS proteins were analyzed. In contrast to the distinct affinities toward phosphoinositides, these IRS-N fragments non-selectively inhibited insulin-induced tyrosine phosphorylation of IRS-1, IRS-2 and IRS-3, among which IRS3-N was most effective. The mutations of IRS-1 disrupting all the phosphoinositide-binding sites in both the PH and PTB domains significantly but not completely suppressed tyrosine phosphorylation of IRS-1, which was further inhibited by coexpression of all the IRS-N proteins examined.

[Emergent operation for a patient of duodenal bleeding accompanied with fulminant myocarditis].

A 53-year-old woman developed general fatigue following an upper airway infection, which abruptly progressed to cardiogenic shock showing systolic blood pressure of 60 mmHg. An echocardiography revealed an ejection fraction of 0.11, diffuse severe hypokinesis and left ventricular thrombosis.

Extracellular proteome of human hepatoma cell, HepG2 analyzed using two-dimensional liquid chromatography coupled with tandem mass spectrometry.

Secreted proteins, which may be involved in the regulation of various biological processes, are the potential targets for diagnosis and treatment of diverse diseases. In this study, to identify the human hepatoma HepG2 cells-derived secreted proteins more extensively, we applied the protein sample preparations using the combinations of denaturation methods and molecular-mass cutoff via ultrafiltration to the two-dimensional liquid chromatography coupled with tandem mass spectrometry (2D LC-MS/MS) analysis. We were able to identify a total of 86 proteins containing widely known secreted proteins of HepG2 such as alpha-fetoprotein, of which 73 proteins including 27 signal peptide-containing proteins have never been reported to be secreted from HepG2 cells in other proteomic studies.

Beneficial effects of tandospirone on ataxia of a patient with Machado-Joseph disease.

Tandospirone citrate (tandospirone) is an anti-anxiety drug that acts by combining with serotonin receptor (5-hydroxytryptamine-1 A [5-HT1A]). Recently, there have been a few reports of its potential role in the treatment of cerebellar ataxia. We report the first case of a patient with Machado-Joseph disease in which we successfully treated cerebellar ataxia.
