PURPOSE: To report the findings in three cases in which the average foveal thickness was increased after a thin epiretinal membrane (ERM) was removed by vitrectomy with internal limiting membrane (ILM) peeling. METHODS: The foveal contour was normal preoperatively in all eyes. All cases underwent successful phacovitrectomy with ILM peeling for a thin ERM. The optical coherence tomography (OCT) images were examined before and after the surgery. The changes in the average foveal (1 mm) thickness and the foveal areas within 500 μm from the foveal center were measured...

Precise mapping between sound and motion underlies successful communication and information transmission in speech and musical performance. Formation of the map typically undergoes plastic changes in the neuronal network between auditory and motor regions through training. However, to what extent the map is somatotopically-tuned so that auditory information can specifically modulate the corticospinal system responsible for the relevant motor action has not been elucidated. Here we addressed this issue by assessing the excitability of corticospinal system including the primary motor cortex (M1) innervating the hand intrinsic muscles by means of transcranial magnetic stimulation while trained pianists and musically-untrained individuals (non-musicians) were listening to either piano tones or noise...

In Japan, we conducted proficiency testing of activity measurement by using high-purity germanium detectors for (134)Cs and (137)Cs in brown rice grains. Among 176 reported results, 86 % (for (134)Cs) and 93 % (for (137)Cs) of the results satisfied |En| ≦ 1. However, 58 reports for (134)Cs and 51 reports for (137)Cs had some failures in their evaluations of uncertainties. The proficiency testing was effective to improve the ability of uncertainty evaluation.

BACKGROUND: Avian antigen is a common cause of hypersensitivity pneumonitis (HP). Inhalation challenge with pigeon serum and pigeon dropping extract (PDE) elicits a hypersensitivity reaction in patients with bird-related hypersensitivity pneumonitis (BRHP), but the antigenic components in these materials have yet to be fully elucidated. METHOD: Pigeon serum, pigeon intestine homogenates, and PDE were immunoblotted with serum samples from 8 patients with BRHP, 2 patients with summer-type HP, 2 patients with humidifier lung, and 3 healthy volunteers...

Mowat-Wilson syndrome (MOWS) is a congenital disease caused by de novo heterozygous loss of function mutations or deletions of the ZEB2 gene. MOWS patients show multiple anomalies including intellectual disability, a distinctive facial appearance, microcephaly, congenital heart defects and Hirschsprung disease. However, the skin manifestation(s) of patients with MOWS has not been documented in detail. Here, we recognized that MOWS patients exhibit many Ehlers-Danlos syndrome (EDS)-like symptoms, such as skin hyperextensibility, atrophic scars and joint hypermobility...

Objective Macrovascular diseases and urgency incontinence are common among Japanese patients with type 2 diabetes mellitus. However, little evidence exists regarding the association between stroke and urgency incontinence among patients with type 2 diabetes mellitus. We examined the associations between macrovascular complications and urgency incontinence among Japanese patients with type 2 diabetes mellitus. Methods The study subjects were 818 Japanese patients with type 2 diabetes mellitus. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate?" We adjusted our analyses for sex, age, body mass index, duration of type 2 diabetes, current smoking, current drinking, hypertension, dyslipidemia, glycated hemoglobin, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy...

Muscle wasting or sarcopenia contributes to morbidity and mortality in patients with cancer, renal failure, or heart failure, and in elderly individuals. Na(+)-K(+)-2Cl(-) cotransporter 1 (NKCC1) is highly expressed in mammalian skeletal muscle, where it contributes to the generation of membrane ion currents and potential. However, the physiologic function of NKCC1 in myogenesis is unclear. We investigated this issue using the NKCC1 inhibitors bumetanide and furosemide, which are commonly used loop diuretics...

Atrial fibrillation is the most common cardiac arrhythmia and leads to stroke. To investigate genetic loci associated with atrial fibrillation in the Japanese population, we performed a genome-wide association study (GWAS) that included 8,180 atrial fibrillation cases and 28,612 controls with follow-up in an additional 3,120 cases and 125,064 controls. We replicated previously reported loci and identified six new loci, near the KCND3, PPFIA4, SLC1A4-CEP68, HAND2, NEBL and SH3PXD2A genes. Five of the six new loci were specifically associated with atrial fibrillation in the Japanese population after comparing our data to those from individuals of European ancestry, suggesting that there might be different genetic factors affecting susceptibility across ancestry groups...

The chorioallantoic membrane (CAM) containing tiny blood vessels is an alternative to large animals for studies involving angiogenesis and tissue engineering. However, there is no technique to design the direction of growing blood vessels on the CAM at the microscale level for tissue engineering experiments. Here, a methodology is provided to direct blood vessel formation on the surface of a three-dimensional egg yolk using a cubic artificial eggshell with six functionalized membranes. A structure on the lateral side of the eggshell containing a straight channel and an interlinked chamber was designed, and the direction and formation area of blood vessels with blood flow was artfully defined by channels with widths of 70-2000 μm, without sharply reducing embryo viability...

Ammonia is one of the members of odor gases and a possible source of odor in indoor environment. However, little has been known on the actual emission rate of ammonia from the human skin surface. Then, this study aimed to estimate the whole-body dermal emission rate of ammonia by simultaneous and multi-point measurement of emission fluxes of ammonia employing a passive flux sampler - ion chromatography system. Firstly, the emission fluxes of ammonia were non-invasively measured for ten volunteers at 13 sampling positions set in 13 anatomical regions classified by Kurazumi et al...

Atmospheric water is a resource equivalent to ~10% of all fresh water in lakes on Earth. However, an efficient process for capturing and delivering water from air, especially at low humidity levels (down to 20%), has not been developed. We report the design and demonstration of a device based on porous metal-organic framework-801 [Zr6O4(OH)4(fumarate)6] that captures water from the atmosphere at ambient conditions using low-grade heat from natural sunlight below one sun (1 kW per square meter). This device is capable of harvesting 2...

AIMS/INTRODUCTION: Overproduction of reactive oxygen species (ROS) in endothelial cells (ECs) plays a pivotal role in endothelial dysfunction. Mitochondrial ROS (mtROS) is one of the key players in the pathogenesis of diabetic vascular complications. Hypoglycemia is linked to increased ROS production and vascular events; however, the underlying mechanisms remain unclear. In this study, we aimed to determine whether and how low glucose (LG) mediates mtROS generation in ECs and to examine the impact of LG-induced mtROS on endothelial dysfunction...

The GABA type A receptor (GABAA-R) is a major target of intravenous anesthetics. Phospholipase C-related inactive protein type-1 (PRIP-1) is important in GABAA-R phosphorylation and membrane trafficking. In this study, we investigated the role of PRIP-1 in general anesthetic action. The anesthetic effects of propofol, etomidate, and pentobarbital were evaluated in wild-type and PRIP-1 knockout (PRIP-1 KO) mice by measuring the latency and duration of loss of righting reflex (LORR) and loss of tail-pinch withdrawal response (LTWR)...

10,15-20-Tris(pentafluorophenyl)-substituted NiII-porphyrin meso-oxy radical bearing two coordinating pyridines was synthesized as a stable radical with a quartet ground state (S = 3/2). X-ray structural analysis has revealed that the NiII porphyrin moiety is fairly planar and the Ni-N bond lengths are considerably longer, indicating the high-spin state of the NiII center. The radical exhibited a quartet ground state, indicating the ferromagnetic interaction between the high-spin NiII center (S = 1) and the porphyrin meso-oxy radical (S = 1/2)...
