Abstract
This study aimed to assess whether preoperative oxidative stress levels can predict postoperative complications in patients undergoing cardiac surgery. Ninety-five cardiac surgery patients received an assessment of preoperative oxidative stress by measurement of hydroperoxide values in blood via the d-Rom test. Area under the receiver operating characteristic curve and also multivariate logistic regression were used to evaluate the prognostic significance of preoperative hydroperoxide concentrations in predicting the occurrence of major organ morbidity and mortality (MOMM). MOMM included death, deep sternal infection, reoperation, stroke, renal failure requiring haemodialysis and prolonged ventilation (>48 hours). The ability of preoperative hydroperoxide concentrations to predict MOMM was not significantly different from that of the European system for cardiac operative risk evaluation (EuroSCORE) (area under the receiver operating characteristic curve 0.822 versus 0.821 respectively, P=0.983). The optimal threshold value of hydroperoxide concentration to differentiate between patients with and without MOMM was 450 UCarr (sensitivity, 87.0%; specificity, 81.9%). Duration of intensive care unit stay, mechanical ventilation time and hospital stay were significantly longer in patients with preoperative hydroperoxide concentrations ≥450 UCarr (H group) compared to those patients with preoperative hydroperoxide concentrations <450 UCarr (L group). An increase in preoperative hydroperoxide concentrations remained associated with an increased risk of MOMM (odds ratios: 1.01, 95% confidence interval: 1.00 to 1.03) and prolonged intensive care unit stay (odds ratio 1.01, 95% confidence interval: 1.00 to 1.02), after adjusting for age, gender and EuroSCORE. In conclusion, an increased hydroperoxide concentration before cardiac surgery is an independent risk factor for severe postoperative complications.

Abstract
Myotonic dystrophy type 1 (DM1) is caused by transcription of CUG repeat RNA, which causes sequestration of muscleblind-like 1 (MBNL1) and upregulation of CUG triplet repeat RNA-binding protein (CUG-BP1). In DM1, dysregulation of these proteins contributes to many aberrant splicing events, causing various symptoms of the disorder. Here, we demonstrate the occurrence of aberrant splicing of LIM domain binding 3 (LDB3) exon 11 in DM1 skeletal muscle. Exon array surveys, RT-PCR, and western blotting studies demonstrated that exon 11 inclusion was DM1 specific and could be reproduced by transfection of a minigene containing the CTG repeat expansion. Moreover, we found that the LDB3 exon 11-positive isoform had reduced affinity for PKC compared to the exon 11-negative isoform. Since PKC exhibits hyperactivation in DM1 and stabilizes CUG-BP1 by phosphorylation, aberrant splicing of LDB3 may contribute to CUG-BP1 upregulation through changes in its affinity for PKC.

Abstract
The up-regulation of c-fos gene expression is widely used as a marker of neuronal activation elicited by various stimuli. Anatomically precise observation of c-fos gene products can be achieved at the RNA level by in situ hybridisation or at the protein level by immunocytochemistry. Both of these methods are time and labour intensive. We have developed a novel transgenic rat system that enables the trivial visualisation of c-fos expression using an enhanced green fluorescent protein (eGFP) tag. These rats express a transgene consisting of c-fos gene regulatory sequences that drive the expression of a c-fos-eGFP fusion protein. In c-fos-eGFP transgenic rats, robust nuclear eGFP fluorescence was observed in osmosensitive brain regions 90 min after i.p. administration of hypertonic saline. Nuclear eGFP fluorescence was also observed in the supraoptic nucleus (SON) and paraventricular nucleus (PVN) 90 min after i.p. administration of cholecystokinin (CCK)-8, which selectively activates oxytocin (OXT)-secreting neurones in the hypothalamus. In double transgenic rats that express c-fos-eGFP and an OXT-monomeric red fluorescent protein 1 (mRFP1) fusion gene, almost all mRFP1-positive neurones in the SON and PVN expressed nuclear eGFP fluorescence 90 min after i.p. administration of CCK-8. It is possible that not only a plane image, but also three-dimensional reconstruction image may identify cytoplasmic vesicles in an activated neurone at the same time.

Abstract
Background Reversible cerebral vasoconstriction syndrome is characterized by thunderclap headache and reversible cerebral vasoconstriction on angiographic findings. It can be difficult to diagnose when initial angiography is normal. Case results A 30-year-old woman was admitted because of sudden-onset thunderclap headache and seizure on postpartum day 7. Brain MRI on fluid-attenuated inversion recovery (FLAIR) showed hyperintense vessel sign (HVS), which usually means slow flow due to severe proximal arterial stenosis. However, magnetic resonance angiography (MRA) indicated that proximal arteries was normal. After nicardipine treatment, her symptoms improved dramatically. Follow-up FLAIR on day 7 showed complete resolution of HVS, while a series of MRAs revealed reversible multifocal segmental vasoconstriction. Conclusions HVS on initial FLAIR is useful for an early diagnosis of reversible cerebral vasoconstriction syndrome. As the delayed vasoconstriction on MRA can be observed, reversible cerebral vasoconstriction syndrome may progress from distal small to proximal larger arteries.

Abstract
Myotonic dystrophy type 2 (DM2) is more common than DM1 in Europe and is considered a rare cause of myotonic dystrophies in Asia. Its clinical course is also milder with more phenotypic variability than DM1. We herein describe the first known Asian family (three affected siblings) with DM2 based on clinical and genetic analyses. Notably, two of the affected siblings were previously diagnosed with limb-girdle muscular dystrophy. Myotonia (the inability of the muscle to relax) was absent or only faintly present in these individuals. The third sibling had grip myotonia and is the first known Asian DM2 patient. The three DM2 siblings share several systemic characteristics, including late-onset, proximal-dominant muscle weakness, diabetes, cataracts and asthma. Repeat-primed PCR across the DM2 repeat revealed a characteristic ladder pattern of a CCTG expansion in all siblings. Southern blotting analysis identified the presence of 3400 repeats. Further DM2 studies in Asian populations are needed to define the clinical presentation of Asian DM2 and as yet unidentified phenotypic differences from Caucasian patients.
