The genetic basis controlling language development remains elusive. Previous studies of the catechol-O-methyltransferase (COMT) Val(158)Met genotype and cognition have focused on prefrontally guided executive functions involving dopamine. However, COMT may further influence posterior cortical regions implicated in language perception. We investigated whether COMT influences language ability and cortical language processing involving the posterior language regions in 246 children aged 6-10 years. We assessed language ability using a language test and cortical responses recorded during language processing using a word repetition task and functional near-infrared spectroscopy...

Snakebite is a serious occupational hazard affecting mainly rural populations of tropical and subtropical developing countries. Lachesis muta (Bushmaster) bites are extremely serious but are rarely reported in the literature. Bushmaster envenomings are characterized by intense local pain, edema, neurotoxicity, hypotension, local hemorrhage, and dramatic systemic alterations. Antivenom treatment has regularly been used for more than a century; however, it fails to neutralize local tissue damage and hemorrhage, leading to morbidity or disabilities in victims...

The concept of a CpG island methylator phenotype (CIMP) was first introduced by Toyota and Issa to describe a subset of colorectal cancers (CRCs) with concurrent hypermethylation of multiple CpG island loci. The concept of CIMP as a molecular carcinogenesis mechanism was consolidated by the identification of the serrated neoplasia pathway, in which CIMP participates in the initiation and progression of serrated adenomas. Distinct clinicopathological and molecular features of CIMP-high (CIMP-H) CRCs have been characterized, including proximal colon location, older age of onset, female preponderance, and frequent associations of high-level microsatellite instability and BRAF mutations...

BACKGROUND: The ACC/AHA guidelines introduced a new classification of severe aortic stenosis (AS) mainly based on maximum jet velocity (Vmax) and mean pressure gradient (mPG), but not on aortic valve area (AVA). However, prognostic value of this new classification has not yet been fully evaluated. METHODS AND RESULTS: We studied 1512 patients with asymptomatic severe AS enrolled in the CURRENT AS registry in whom surgery was not initially planned. Patients were divided into 2 groups: Group 1 (N=122) comprised patients who met the recommendation for surgery; high-gradient (HG)-AS (Vmax≥4...

Introduction Determining the full extent of gliomas during radiotherapy planning can be challenging with conventional T1 and T2 magnetic resonance imaging (MRI). The purpose of this study was to develop a method to automatically calculate differences in the fractional anisotropy (FA) and mean diffusivity (MD) values in target volumes obtained with diffusion tensor imaging (DTI) by comparing with values from anatomically homologous voxels on the contralateral side of the brain. Methods Seven patients with a histologically confirmed glioma underwent postoperative radiotherapy planning with 1...

We report a case of aphasia after neck clipping of a ruptured aneurysm at the origin of the duplicated middle cerebral artery(DMCA). A 60-year-old woman had a sudden onset of headache and nausea. A computed tomography(CT)scan revealed diffuse subarachnoid hemorrhage. Head three-dimensional CT angiography(3D-CTA)showed a left DMCA with a saccular aneurysm at the origin. She became aphasic on the third day after aneurysmal neck clipping. A CT scan revealed a low-density area in the anterior portion of the left temporal lobe, which is perfused by the DMCA...

A 40-year-old woman was noted to have clubbing of the nails during an outpatient service for smoking cessation. Chest computed tomography showed an aneurysm of an aberrant artery running from the descending aorta to the left lower lobe. Hence, we diagnosed anomalous systemic arterialization of the lung. The proximal part of the aberrant artery measured 13 mm in diameter;moreover, it had developed an aneurysm(17 mm in diameter) in the lung parenchyma. The aberrant artery was ligated with a covering material (absorbable felt) and cut via a small access thoracotomy by a cardiovascular surgeon;subsequently, left lower lobectomy was performed...

BACKGROUND: Studies investigating the relationship between n-3 polyunsaturated fatty acid (PUFA) levels and psychiatric disorders have thus far focused mainly on analyzing gray matter, rather than white matter, in the postmortem brain. In this study, we investigated whether PUFA levels showed abnormalities in the corpus callosum, the largest area of white matter, in the postmortem brain tissue of patients with schizophrenia, bipolar disorder, or major depressive disorder. METHODS: Fatty acids in the phospholipids of the postmortem corpus callosum were evaluated by thin-layer chromatography and gas chromatography...

Macroautophagy is an intracellular degradation system that utilizes the autophagosome to deliver cytoplasmic components to the lysosome. Measuring autophagic activity is critically important but remains complicated and challenging. Here, we have developed GFP-LC3-RFP-LC3ΔG, a fluorescent probe to evaluate autophagic flux. This probe is cleaved by endogenous ATG4 proteases into equimolar amounts of GFP-LC3 and RFP-LC3ΔG. GFP-LC3 is degraded by autophagy, while RFP-LC3ΔG remains in the cytosol, serving as an internal control...

Gravitropism in Arabidopsis shoots depends on the sedimentation of amyloplasts in the endodermis, and a complex interplay between the vacuole and F-actin. Gravity response is inhibited in zigzag-1 (zig-1), a mutant allele of VTI11, which encodes a SNARE protein involved in vacuole fusion. zig-1 seedlings have fragmented vacuoles that fuse after treatment with wortmannin, an inhibitor of phosphatidylinositol 3-kinase, and underscore a role of phosphoinositides in vacuole fusion. Using live-cell imaging with a vertical stage microscope, we determined that young endodermal cells below the apical hook that are smaller than 70 μm in length are the graviperceptive cells in dark-grown hypocotyls...

Given the complexity and heterogeneity of the genomic architecture underlying schizophrenia, molecular analyses of these patients with defined and large effect-size genomic defects could provide valuable clues. We established human-induced pluripotent stem cells from two schizophrenia patients with the 22q11.2 deletion (two cell lines from each subject, total of four cell lines) and three controls (total of four cell lines). Neurosphere size, neural differentiation efficiency, neurite outgrowth, cellular migration and the neurogenic-to-gliogenic competence ratio were significantly reduced in patient-derived cells...

Forward genetics is a powerful approach used to link genotypes and phenotypes, and mutant screening/analysis has provided deep insights into many aspects of plant physiology. Gravitropism is a tropistic response in plants, in which hypocotyls and stems sense the direction of gravity and grow upward. Previous studies of gravitropic mutants have suggested that shoot endodermal cells in Arabidopsis stems and hypocotyls are capable of sensing gravity (i.e., statocytes). In the present study, we report a new screening system using hypergravity conditions to isolate enhancers of gravitropism mutants, and we also describe a rapid and efficient genome mapping method, using next-generation sequencing (NGS) and single nucleotide polymorphism (SNP)-based markers...

One-month duration of dual antiplatelet therapy (DAPT) has widely been adopted after bare-metal stent (BMS) implantation in the real clinical practice. However, it has not been adequately addressed yet whether DAPT for only 1-month could provide sufficient protection from ischemic events beyond 1-month after BMS implantation. We assessed the effects of short DAPT relative to prolonged DAPT on clinical outcomes with the landmark analysis at 2 month after BMS implantation. Among 13,058 consecutive patients enrolled in the CREDO-Kyoto registry cohort-2, this study population consisted of 4905 patients treated with BMS only in whom the information on the status of antiplatelet therapy was available at 2 month after stent implantation [single-antiplatelet therapy (SAPT) group: N = 2575 (acute myocardial infarction (AMI): N = 1257, and non-AMI: N = 1318), and DAPT group: N = 2330 (AMI: N = 1304, and non-AMI: N = 1026)]...
