Abstract
BACKGROUND Vascular targeted photodynamic therapy (PDT) is a novel and promising therapy for the treatment of port-wine stains (PWS). There has been little prior exploration to our knowledge of how the dermatological vascular pattern may predict the response to PDT. OBJECTIVES To analyse whether the vascular pattern classifications of PWS by dermoscopy can predict the efficacy of PDT. METHODS This prospective cohort study included 163 patients with a clinical diagnosis of PWS who were treated twice with hemoporfin-mediated photodynamic therapy (HMME-PDT) at two-month intervals and followed up for 6 months. The vascular manifestations of dermoscopy with PWS were independently classified into 8 categories by 3 dermatologists. Images of the lesions were taken using VISIA, and the vascular patterns were imaged by dermoscopy by the same investigator. Images were captured before and after each treatment. The efficacy was evaluated with pre- and post-treatment VISIA images, and correlations between efficacy and vascular patterns were analysed by four dermatologists in a blinded and independent manner, between 10 January 2019 and 11 December 2019. RESULTS In the dermoscopy images for the whole cohort, dotted and globular vessels (15.3%), short clubbed vessels (18.4%) and curved vessels (12.9%) were highly associated with cure and beneficial treatment effects. Pale halos surrounding brown dots (8.0%) and arborizing vessels (9.8%) were mainly correlated with skin lesion alleviation. Mixed vessels (12.9%), a grey-whitish veil (11.7%) and reticular patterns (11.0%) were mainly associated with no effect. The differences between each subgroup were statistically significant (P = 0.000). CONCLUSIONS There is a clear correlation between the efficacy of PDT and the dermoscopy pattern in patients with PWS. Dermoscopy may therefore provide very useful clinical information prior to treatment in these cases. In addition, the vascular manifestations of PWS determined by dermoscopy help to predict response to PDT and manage patient expectations.

Abstract
Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7-δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with different tilt angles are characterized by the probability distributions of avalanche size in terms of the number of moving vortices. It is found in both samples that these distributions follow power-laws over up to three decades, and have exponents ranging between 1.0 and 1.4. The distributions also show clear finite-size scaling, when the system size is defined by the depth of the flux penetration front - a signature of self-organized criticality. A scaling relation between the avalanche size exponent and the fractal dimension, previously derived theoretically from conservation of the number of magnetic vortices in the stationary state and shown in numerical simulations, is here shown to be satisfied also experimentally.

Abstract
The transcription regulator, neuron-restrictive silencer factor (NRSF), also known as repressor element-1 silencing transcription factor (REST), plays an important role in neurogenesis and various neuronal diseases such as ischaemia, epilepsy, and Huntington's disease. In these disease processes, neuronal loss is associated with abnormal expression and/or localization of NRSF. Previous studies have demonstrated that NRSF regulates the effect of ethanol on neuronal cells in vitro, however, the role of NRSF in ethanol-induced neuronal cell death remains unclear. We generated nrsf conditional knockout mice using the Cre-loxP system to disrupt neuronal expression of nrsf and its truncated forms. At postnatal day 6, ethanol significantly increased the expression of REST4, a neuron-specific truncated form of NRSF, in the brains of wild type mice, and this effect was diminished in nrsf conditional knockout mice. The apoptotic effect of ethanol was pronounced in multiple brain regions of nrsf conditional mutant mice. These results indicate that NRSF, specifically REST4, may protect the developing brain from ethanol, and provide new evidence that NRSF can be a therapeutic target in foetal alcohol syndrome (FAS).

Abstract
A case of 38-year-old male with adult onset phosphoglucomutase (PGM) deficiency was reported. The patient was admitted at Kawamura Hospital (Gifu City) for evaluation of easy fatiguability and exercise-induced weakness of the extremities since he was 20 years old. Physical examination revealed moderate muscle weakness, wasting of extremities, bilateral clubbed fingers and hypoesthesia of distal portion of extremities. Fasting plasma glucose was low (58 mg/dl). Venous concentration of lactate failed to rise after an ischemic forearm exercise test. An epinephrine tolerance test revealed hyperglycemic response. Studies of anaerobic glycolysis in vitro using muscle homogenates with the substrate between glucose-1-phosphate and glucose-6-phosphate showed decreased lactate production. Direct assay of individual muscle glycolytic enzymes demonstrated reduction of PGM activity (15% of normal, n = 12). Biopsy study with PAS staining of quadriceps femoris muscle demonstrated small amount of deeply staining glycogen in subsarcolemmal area. Electron microscopic examination revealed muscle destruction with small amount of glycogen in subsarcolemmal and intermyofibrillar spaces. Sural nerve biopsy showed degeneration of myelinated and unmyelinated fibers but there was no apparent accumulation of glycogen. From the clinical, biochemical and histopathological evidences, the patient might be a rare case of adult onset PGM deficiency.
