The purpose of the current study was to investigate the structure-function relationship in patients with retinitis pigmentosa (RP) using optical coherence tomography and the MP-3 microperimeter. Visual field (VF) measurements were carried out using MP-3 microperimetry and the Humphrey Field Analyzer (HFA, Carl-Zeiss, CA), 22 eyes of 11 patients with a clinical diagnosis of RP, both with the 10-2 test grid pattern. Optical coherence tomography (OCT, Spectralis, Heidelberg, Germany) was also performed and the ellipsoid zone (EZ) was identified in the OCT image...

Chrononutrition is the science of nutrition based on chronobiology. Numerous epidemiological studies have shown that fish oil (FO) reduces the risk of cardiovascular events through various actions such as lowering triglycerides. The present study aimed to determine the time of day when the hypertriglyceridemia-decreasing ability of FO is optimal in mice. A high-fructose diet (HFrD) that induces hyperlipidemia in mice was replaced with the same diet containing 4% FO (HFrD-4% FO) at different times of the day for 2 weeks as described below...

Producing ionic liquids (ILs) that function as molecular machines for macroscopic change is a challenging issue. We report that photoisomerization of an azobenzene IL at the molecular level could evoke a macroscopic response (light-controlled mechanical sol-gel transitions) for ABA triblock copolymer solutions. The A endblocks, poly(2-phenylethyl methacrylate), show a low critical solution temperature in the IL mixture containing azobenzene while the B midblock, poly(methyl methacrylate), is compatible with the mixture...

The ratio of serum eicosapentaenoic acid (EPA) to arachidonic acid (AA) is significantly associated with long-term clinical outcomes in patients with acute myocardial infarction (AMI). However, it has not been conclusively demonstrated that higher serum EPA/AA ratio fares better clinical outcomes in the early phase of AMI. The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective multicenter registry conducted in 28 Japanese medical institutions between July 2012 and March 2014...

Accumulating evidence suggests a key role of the gut-microbiota-brain axis in the antidepressant actions of certain compounds. Ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, showed rapid and sustained antidepressant effects in treatment-resistant depressed patients. In contrast, another NMDAR antagonist, lanicemine, did not exhibit antidepressant effects in such patients. (R)-ketamine, the (R)-enantiomer of ketamine, has rapid-acting and long-lasting antidepressant effects in rodent models of depression...

BACKGROUND: Cerebral hyperperfusion syndrome (CHS) is known to be a rare but devastating complication of carotid artery revascularization. Because patients with acute ischemic stroke due to acute major cerebral and/or cervical artery occlusion treated with endovascular reperfusion therapy may have impaired autoregulation in the cerebral vasculature, these patients may also develop CHS. Despite the growing number of endovascular reperfusion procedures for acute ischemic stroke, this complication has only rarely been reported...

Triglyceride deposit cardiomyovasculopathy (TGCV) is a rare and newly identified disease among patients requiring cardiac transplantation. TGCV is characterized by cardiomyocyte steatosis and triglyceride (TG)-deposit atherosclerosis, resulting from the abnormal intracellular metabolism of TG. TGCV is classified into primary and idiopathic types. Primary TGCV carries ultra-rare genetic mutations in the adipose triglyceride lipase (ATGL), a rate-liming enzyme that hydrolyzes intracellular TG in adipose and non-adipose tissues...

The lack of a highly sensitive and simple method for the quantitative analysis of glycan has impeded the exploration of protein glycosylation patterns (glycomics), evaluation of antibody drug stability, and screening of disease glycan biomarkers. In this study, we describe a novel and simplified quantitative glycomics strategy. Quantitation by mutant enzyme reaction stable isotope labeling (QMERSIL) to label the N-glycans with either a nondeuterated (d0-) or deuterated (d8-) 4-(2,4-Dinitro-5-piperazin-1-yl-phenyl)-1,1-dimethyl-piperazin-1-ium (MPDPZ)-Boc-asparaginyl-N-acetyl-d-glucosamine (Boc-Asn-GlcNAc) acceptor of a positive charge structure through the glycosynthase (Endo-M-N175Q) transglycosylation reaction with mass spectrometry facilitates comparative glycomics...

Deep-sea hydrothermal vent is one of the most extreme environments on Earth with low oxygen and high levels of toxins. Decapod species from the family Alvinocarididae have colonized and successfully adapted to this extremely harsh environment. Mitochondria plays a vital role in oxygen usage and energy metabolism, thus it may be under selection in the adaptive evolution of the hydrothermal vent shrimps. In this study, the mitochondrial genome (mitogenome) of alvinocaridid shrimp Shinkaicaris leurokolos (Kikuchi & Hashimoto, 2000) was determined through Illumina sequencing...

A new genus, Brevicollum, is established for two new species, B. hyalosporum on Syzygium samarangense and B. versicolor on Volkameria inermis, in Japan. This genus is characterized by the presence of immersed ascomata with an excentric to central, short cylindrical ostiolar neck, thin ascomatal wall, clavate asci with a shallow ocular chamber, and broadly fusiform, hyaline to pale brown ascospores with a sheath. Molecular phylogenetic analyses based on a combined data set of sequences of 18S and 28S nuc rDNA genes and the second largest subunit of RNA polymerase II (RPB2) revealed that Brevicollum is a member of Neohendersoniaceae (Pleosporales, Dothideomycetes)...

Vibrio vulnificus is known as an opportunistic bacterial pathogen that causes primary septicemia and wound infection in humans. Recently, the incidence of wound infection by V. vulnificus is increasing in warm countries. In this study, we examined a vaccine antigen against V. vulnificus in mice. FlaB, a component protein of the V. vulnificus flagellum, was expressed as a recombinant protein, named rFlaB. After immunization of mice with rFlaB, the mice were challenged by subcutaneous inoculation with V. vulnificus...

Increased numbers of CD8(+)CD28(neg.) T cells have been detected in the peripheral blood of patients with several types of malignancies. However, the role of these cells in anticancer immunity are not yet clear and CD8(+)CD28(neg.) T cells are a controversially discussed subpopulation reported both as immunosuppressive and cytotoxic. In this study, we examined the T cell receptor (TCR) repertoire and complementarity-determining region 3 sequences of CD28(neg.) T cells in a melanoma patient with recurrent disease who achieved long-term disease-free status...

Scirrhous type gastric cancer is characterized by diffuse infiltration of poorly differentiated adenocarcinoma cells and poor prognosis. Although association of poorly differentiated histology with reduction in E-cadherin expression, as well as association of microRNA (miR)-200c with E-cadherin through regulation of ZEB1/2, has been reported, participation of miR-200c in gastric carcinogenesis is not fully understood. We used 6 cell lines originating from gastric cancers, and investigated levels of miR-200c along with its target mRNAs ZEB1/2 and E-cadherin by qRT-PCR...

We herein report a case of a retroperitoneal tumor of unknown origin that was diagnosed as a seminoma after tumor biopsy and was successfully treated with chemotherapy containing bleomycin, etoposide, and cisplatin(BEP). A 47-year old man visited our hospital with left abdominal pain. An endoscopic examination revealed an ulcer lesion on the third part of the duodenum. Abdominal CT scan revealed a retroperitoneal tumor invading the abdominal aorta with the tumor thrombus in the inferior vena cava(IVC). An endoscopic biopsy could not identify the tumor's origin because of the negative staining of various surface markers on immunohistochemistry...

The short tapered-wedge stem is popular worldwide because it potentially preserves more bone stock during total hip arthroplasty (THA). However, stem version mismatch may affect physiological stress distribution. In this study, we analyzed the correlations between periprosthetic bone mineral density (BMD) changes and anteversion mismatch in patients who underwent THA using a short tapered-wedge stem. The study included 44 patients (44 joints) who underwent THA with a Tri-Lock stem. At baseline and at 6 and 24 months postoperatively, the BMDs in the seven Gruen zones were evaluated using dual-energy X-ray absorptiometry...
