Abstract
Several generations of ATP-competitive anti-cancer drugs that inhibit the activity of the intracellular kinase domain of the epidermal growth factor receptor (EGFR) have been developed over the past twenty years. The first-generation of drugs such as gefitinib bind reversibly and were followed by a second-generation such as dacomitinib that harbor an acrylamide moiety that forms a covalent bond with C797 in the ATP binding pocket. Resistance emerges through mutation of the T790 gatekeeper residue to methionine, which introduces steric hindrance to drug binding and increases the Km for ATP. A third generation of drugs, such as osimertinib were developed which were effective against T790M EGFR in which an acrylamide moiety forms a covalent bond with C797, although resistance has emerged by mutation to S797. A fragment-based screen to identify new starting points for an EGFR inhibitor serendipitously identified a fragment that reacted with C775, a previously unexploited residue in the ATP binding pocket for a covalent inhibitor to target. A number of acrylamide containing fragments were identified that selectively reacted with C775. One of these acrylamides was optimized to a highly selective inhibitor with sub-1 μM activity, that is active against T790M, C797S mutant EGFR independent of ATP concentration, providing a potential new strategy for pan-EGFR mutant inhibition.

Abstract
The memories for past autobiographical experiences that we share can influence relationship formation and consolidation with important implications for our mental health. However, little is known about how people's responses to our memories can influence subsequent memory sharing. Previous research examined how operant processes (i.e., punishment with aversive sounds) influence the sharing of memories for specific events from our past. Understanding the (social) mechanisms associated with difficulty sharing specific autobiographical memories is important given the association between these difficulties and a range of psychiatric diagnoses. We investigate the effects of verbal and non-verbal social operants on the willingness to share specific autobiographical memories. Participants shared memories with a confederate who coded their memories as specific or non-specific and responded in either an engaged/attentive, dismissive manner or gave no feedback depending on participants' assigned condition. Participants who were reinforced for sharing specific memories and punished for sharing non-specific memories, were more likely to share specific than non-specific memories compared to those who received no feedback. Reinforcement alone was not sufficient for modifying specificity. The ways that we respond to people when they share memories with us can influence their subsequent willingness to share specific events from their past.

Abstract
Patients with melanoma with activating BRAF mutations (BRAF V600E/K) initially respond to combination therapy of BRAF and MEK inhibitors. However, their clinical efficacy is limited by acquired resistance, in some cases driven by amplification of the mutant BRAF gene and subsequent reactivation of the MAPK pathway. DS03090629 is a novel and orally available MEK inhibitor that inhibits MEK in an ATP-competitive manner. In both in vitro and in vivo settings, potent inhibition of MEK by DS03090629 or its combination with the BRAF inhibitor dabrafenib was demonstrated in a mutant BRAF-overexpressing melanoma cell line model that exhibited a higher MEK phosphorylation level than the parental cell line and then became resistant to dabrafenib and the MEK inhibitor trametinib. DS03090629 also exhibited superior efficacy against a melanoma cell line-expressing mutant MEK1 protein compared with dabrafenib and trametinib. Biophysical analysis revealed that DS03090629 retained its affinity for the MEK protein regardless of its phosphorylation status, whereas the affinity of trametinib declined when the MEK protein was phosphorylated. These results suggest that DS03090629 may be a novel therapeutic option for patients who acquire resistance to the current BRAF- and MEK-targeting therapies.

Abstract
Purpose To improve the performance of a denoising convolutional neural network (DnCNN) and to make it applicable to images with inhomogeneous noise, a refinement involving an activation function (AF) and an application of the refined method for inhomogeneous-noise images was examined in combination with parallelized image denoising. Methods Improvements in the DnCNN were performed by three approaches. One is refinement of the AF of each neural network that constructs the DnCNN. Swish was used in the DnCNN instead of rectifier linear unit. Second, blind noise removal was introduced to the DnCNN in order to adapt spatially variant noises. Third, blind noise removal was applied to parallelized image denoising, referred to herein as ParBID. The ParBID procedure is as follows: (1) adjacent 2D slice images are linearly combined to obtained higher peak SNR (PSNR) images, (2) combined images with different weight coefficients are denoised using the blind DnCNN, and (3) denoised combined images are separated into original position images by algebraic calculation. Results Experimental studies showed that the PSNR and the structural similarity index (SSIM) were improved by using Swish for all noise levels, from 2.5% to 7.5%, as compared to the conventional DnCNN. It was also shown that a well-trained CNN could remove spatially variant noises superimposed on images. Experimental studies with ParBID showed that the greatest PSNR and SSIM improvements were obtained at the middle slice when three slice images were used for linear image combination. More fine structures of images and image contrast remained when the proposed ParBID procedure was used. Conclusion Swish can improve the denoising performance of the DnCNN, and the denoising performance and effectiveness were further improved by ParBID.

Abstract
Contemporary cognitive models of depression propose that cognitive biases for negative information at the level of attention (attention biases; AB) and interpretation (interpretation biases; IB) increase depression risk by promoting maladaptive emotion regulation (ER). So far, empirical support testing interactions between these variables is restricted to non-clinical and clinical adult samples. The aim of the current study was to extend these findings to a sample of children and adolescents. This cross-sectional study included 109 children aged 9–14 years who completed behavioural measures of AB (passive-viewing task) and IB (scrambled sentences task) as well as self-report measures of ER and depressive symptoms. In order to maximize the variance in these outcomes we included participants with a clinical diagnosis of depression as well as non-depressed youth with an elevated familial risk of depression and non-depressed youth with a low familial risk of depression. Path model analysis indicated that all variables (AB, IB, adaptive and maladaptive ER) had a direct effect on depressive symptoms. IB and AB also had significant indirect effects on depressive symptoms via maladaptive and adaptive ER. These findings provide initial support for the role of ER as a mediator between cognitive biases and depressive symptoms and provide the foundations for future experimental and longitudinal studies. In contrast to studies in adult samples, both adaptive as well as maladaptive ER mediated the effect of cognitive biases on depressive symptoms. This suggests potentially developmental differences in the role of ER across the lifespan.

Abstract
Background Youth depression is highly prevalent and is related to impairments in academic, social and behavioural functioning. Evidence-based treatments are available, but many young people do not respond or sufficiently recover with first-line options, and a significant proportion experience relapse. Consequently, there is clear scope to enhance intervention in this critical period of early-onset depression. Memory specificity training (MeST) is a low-intensity intervention for depression that targets reduced specificity when recalling memories of the past, a common cognitive vulnerability in depression. This randomised controlled trial will assess the efficacy of adding a computerised version of MeST (c-MeST) to usual care for youth depression. Methods/design Young people aged 15–25 years with a major depressive episode (MDE) will be recruited and randomised to have immediate access to the seven session online c-MeST program in addition to usual care, or to usual care and wait-list for c-MeST. The primary outcomes will be diagnostic status of an MDE and self-reported depressive symptoms assessed at baseline, 1-, 3- and 6-month intervals. Autobiographical memory specificity and other variables thought to contribute to the maintenance of reduced memory specificity and depression will be assessed as mediators of change. Discussion Online provision of c-MeST provides a simple, low-intensity option for targeting a cognitive vulnerability that predicts the persistence of depressive symptoms. If found to be efficacious as an adjunct to usual care for depressed youth, it could be suitable for broader roll-out, as c-MeST is highly accessible and implementation requires only minimal resources due to the online and automated nature of intervention.

Abstract
BACKGROUND Characteristic of the cardinal symptom of anhedonia, people with clinical depression report lower levels of anticipatory pleasure. However, the psychological mechanisms underlying these deficits are poorly understood. This is the first study to assess whether, and to what extent, phenomenological characteristics of episodic future thinking for positive future events are associated with anticipatory pleasure among depressed individuals. METHODS Individuals with a Major Depressive Episode (MDE; N = 117) and without (N = 47) completed ratings scales for depressive symptoms and trait anticipatory and consummatory pleasure. They then provided descriptions of personally-relevant positive future events and rated them for phenomenological characteristics and state anticipatory pleasure. RESULTS Between-groups analysis showed that those with MDE reported lower trait anticipatory and consummatory pleasure. They also simulated future events with less specificity, less detail/vividness, less use of mental imagery, less use of first-person perspective, less plausibility/perceived likelihood of occurring, and reported less associated state anticipatory pleasure. In regression analyses in the depressed group, lower scores for detail/vividness, mental imagery, and personal significance all uniquely predicted lower state anticipatory pleasure. LIMITATIONS Cognitive functioning was not assessed, which may help clarify deficits that underpin these findings. History of previous depressive episodes in the comparison group were not assessed, which may mean the observed between-group effects are underestimated. CONCLUSIONS This study provides further evidence of deficits in episodic future thinking and anticipatory pleasure in depressed individuals. It also establishes links between particular characteristics of episodic future thinking and state anticipatory pleasure, and indicates cognitive targets that may be amenable to intervention in order to reduce anhedonia.

Abstract
Ubiquitin-mediated protein degradation plays essential roles in proteostasis and is involved in the pathogenesis of neurodegenerative diseases in which ubiquitin-positive aberrant proteins accumulate. However, how such aberrant proteins are processed inside cells has not been fully explored. Here, we show that the product of CG5445, a previously uncharacterized Drosophila gene, prevents the accumulation of aggregate-prone ubiquitinated proteins. We found that ubiquitin conjugates were associated with CG5445, the knockdown of which caused the accumulation of detergent-insoluble ubiquitinated proteins. Furthermore, CG5445 rescued eye degeneration caused by the amyotrophic lateral sclerosis (ALS)-linked mutant TAR DNA-binding protein of 43 kDa (TDP-43), which often forms ubiquitin-positive aggregates in cells through the capacity of CG5445 to bind to ubiquitin chains. Biochemically, CG5445 inhibited the accumulation of insoluble forms and promoted their clearance. Our results demonstrate a new possible mechanism by which cells maintain ubiquitinated aggregation-prone proteins in a soluble form to decrease their cytotoxicity until they are degraded.

Abstract
In this retrospective analysis using the Transplant Registry Unified Management Program, we identified 145 patients with human herpesvirus (HHV)-6 encephalitis among 6593 recipients. The cumulative incidences of HHV-6 encephalitis at 100 days after transplantation in all patients, recipients of bone marrow or PBSCs and recipients of cord blood were 2.3%, 1.6% and 5.0%, respectively. Risk factors identified in multivariate analysis were male sex, type of transplanted cells (relative risk in cord blood transplantation, 11.09, P<0.001; relative risk in transplantation from HLA-mismatched unrelated donor, 9.48, P<0.001; vs transplantation from HLA-matched related donor) and GvHD prophylaxis by calcineurin inhibitor alone. At 100 days after transplantation, the overall survival rate was 58.3% and 80.5% among patients with and without HHV-6 encephalitis, respectively (P<0.001). Neuropsychological sequelae remained in 57% of 121 evaluated patients. With both foscarnet and ganciclovir, full-dose therapy (foscarnet ⩾180 mg/kg, ganciclovir ⩾10 mg/kg) was associated with better response rate (foscarnet, 93% vs 74%, P=0.044; ganciclovir, 84% vs 58%, P=0.047). HHV-6 encephalitis is not rare not only in cord blood transplant recipients but also in recipients of HLA-mismatched unrelated donors. In this study, development of HHV-6 encephalitis was associated with a poor survival rate, and neurological sequelae remained in many patients.

Abstract
BACKGROUND AND PURPOSE Noninvasive radiologic evaluation of glioma can facilitate correct diagnosis and detection of malignant transformation. Although positron-emission tomography is considered valuable in the care of patients with gliomas, (18)F-fluorodeoxyglucose and (11)C-methionine have reportedly shown ambiguous results in terms of grading and prognostication. The present study compared the diagnostic and prognostic capabilities of diffusion tensor imaging, FDG, and (11)C-methionine PET in nonenhancing gliomas. MATERIALS AND METHODS Thirty-five consecutive newly diagnosed, histologically confirmed nonenhancing gliomas that underwent both FDG and (11)C-methionine PET were retrospectively investigated (23 grade II and 12 grade III gliomas). Apparent diffusion coefficient, fractional anisotropy, and tumor-to-normal tissue ratios of both FDG and (11)C-methionine PET were compared between grade II and III gliomas. Prognostic values of these parameters were also tested by using progression-free survival. RESULTS Grade III gliomas showed significantly higher average tumor-to-normal tissue and maximum tumor2-to-normal tissue than grade II gliomas in (11)C-methionine (P = .013, P = .0017, respectively), but not in FDG-PET imaging. There was no significant difference in average ADC, minimum ADC, average fractional anisotropy, and maximum fractional anisotropy. (11)C-methionine PET maximum tumor-to-normal tissue ratio of 2.0 was most suitable for detecting grade III gliomas among nonenhancing gliomas (sensitivity, 83.3%; specificity, 73.9%). Among patients not receiving any adjuvant therapy, median progression-free survival was 64.2 ± 7.2 months in patients with maximum tumor-to-normal tissue ratio of <2.0 for (11)C-methionine PET and 18.6 ± 6.9 months in patients with maximum tumor-to-normal tissue ratio of >2.0 (P = .0044). CONCLUSIONS (11)C-methionine PET holds promise for World Health Organization grading and could offer a prognostic imaging biomarker for nonenhancing gliomas.

Abstract
To elucidate the impact of pretransplant body mass index (BMI) on the clinical outcome, we performed a retrospective study with registry data including a total of 12 050 patients (age ⩾18 years) who received allogeneic hematopoietic SCT (HSCT) between 2000 and 2010. Patients were stratified as follows: BMI<18.5 kg/m(2), Underweight, n=1791; 18.5⩽BMI<25, Normal, n=8444; 25⩽BMI<30, Overweight, n=1591; BMI⩾30, Obese, n=224. The median age was 45 years (range, 18-77). A multivariate analysis showed that the risk of relapse was significantly higher in the underweight group and lower in the overweight and obese groups compared with the normal group (hazard ratio (HR), 1.16, 0.86, and 0.74, respectively). The risk of GVHD was significantly higher in the overweight group compared with the normal group. The risk of non-relapse mortality (NRM) was significantly higher in the overweight and obese group compared with the normal group (HR 1.19 and HR 1.43, respectively). The probability of OS was lower in the underweight group compared with the normal group (HR 1.10, P=0.018). In conclusion, pretransplant BMI affected the risk of relapse and NRM after allogeneic HSCT. Underweight was a risk factor for poor OS because of an increased risk of relapse. Obesity was a risk factor for NRM.

Abstract
This is the first successful report of a laparoscope-assisted Hassab's operation for esophagogastric varices after living donor liver transplantation (LDLT). A 35-year-old man underwent LDLT using a right lobe graft as an aid for primary sclerosing cholangitis (PSC) in 2005. Follow-up endoscopic and computed tomography (CT) examinations showed esophagogastric varices with splenomegaly in 2009 that increased (esophageal varices [EV]: locus superior [Ls], moderator enlarged, beady varices [F2], medium in number and intermediate between localized and circumferential red color signs [RC2]; gastric varices [GV]: extension from the cardiac orifice to the fornix [Lg-cf], moderator enlarged, beady varices [F2], absent red color signs [RC0]). A portal venous flow to the esophagogastric varices through a large left gastric vein was also confirmed. Preoperative Child-Pugh was grade B and score was 9. Because these esophagogastric varices had a high risk of variceal bleeding, we proceeded with a laparoscope-assisted Hassab's operation. Operative time was 464 minutes. Blood loss was 1660 mL. A graft liver biopsy was also performed and recurrence of PSC was confirmed histologically. It was suggested that portal hypertension and esophagogastric varices were caused by recurrence of PSC. Postoperative complications were massive ascites and enteritis. Both of them were treated successfully. This patient was discharged on postoperative day 43. Follow-up endoscopic study showed improvement in the esophagogastric varices (esophageal varices [EV]: locus superior [Ls], no varicose appearance [F0], absent red color signs [RC0], gastric varices [GV]: adjacent to the cardiac orifice [Lg-c], no varicose appearance [F0], absent red color signs [RC0]) at 6 months after the operation. We also confirmed the improvement of esophagogastric varices by serial examinations of CT.

Green tea ingestion greatly reduces plasma concentrations of nadolol in healthy subjects. Clin Pharmacol Ther 2014; 95:432-8.

Abstract
This study aimed to evaluate the effects of green tea on the pharmacokinetics and pharmacodynamics of the β-blocker nadolol. Ten healthy volunteers received a single oral dose of 30 mg nadolol with green tea or water after repeated consumption of green tea (700 ml/day) or water for 14 days. Catechin concentrations in green tea and plasma were determined. Green tea markedly decreased the maximum plasma concentration (C(max)) and area under the plasma concentration-time curve (AUC(0-48)) of nadolol by 85.3% and 85.0%, respectively (P < 0.01), without altering renal clearance of nadolol. The effects of nadolol on systolic blood pressure were significantly reduced by green tea. [(3)H]-Nadolol uptake assays in human embryonic kidney 293 cells stably expressing the organic anion-transporting polypeptides OATP1A2 and OATP2B1 revealed that nadolol is a substrate of OATP1A2 (Michaelis constant (K(m)) = 84.3 μmol/l) but not of OATP2B1. Moreover, green tea significantly inhibited OATP1A2-mediated nadolol uptake (half-maximal inhibitory concentration, IC(50) = 1.36%). These results suggest that green tea reduces plasma concentrations of nadolol possibly in part by inhibition of OATP1A2-mediated uptake of nadolol in the intestine.

Abstract
BACKGROUND High-mobility group box chromosomal protein 1 (HMGB1) has recently been identified as an important mediator of various kinds of acute and chronic inflammation. A method for efficiently removing HMGB1 from the systemic circulation could be a promising therapy for HMGB1-mediated inflammatory diseases. MATERIALS AND METHODS In this study, we produced a new adsorbent material by chemically treating polystyrene fiber. We first determined whether the adsorbent material efficiently adsorbed HMGB1 in vitro using a bovine HMGB1 solution and a plasma sample from a swine model of acute liver failure. We then constructed a column by embedding fabric sheets of the newly developed fibers into a cartridge and tested the ability of the column to reduce plasma HMGB1 levels during a 4-hour extracorporeal hemoperfusion in a swine model of acute liver failure. RESULTS The in vitro adsorption test of the new fiber showed high performance for HMGB1 adsorption (96% adsorption in the bovine HMGB1 solution and 94% in the acute liver failure swine plasma, 2 h incubation at 37°C; p < 0.05 vs. incubation with no adsorbent). In the in vivo study, the ratio of the HMGB1 concentration at the outlet versus the inlet of the column was significantly lower in swine hemoperfused with the newly developed column (53 and 61% at the beginning and end of perfusion, respectively) than in those animals hemoperfused with the control column (94 and 93% at the beginning and end of perfusion, respectively; p < 0.05). Moreover, the normalized plasma level of HMGB1 was significantly lower during perfusion with the new column than with the control column (p < 0.05 at 1, 2, and 3 h after initiation of perfusion). CONCLUSION These data suggest that the newly developed column has the potential to effectively adsorb HMGB1 during hemoperfusion in swine.

Abstract
BACKGROUND Interleukin (IL)-33 is a novel member of the IL-1 cytokine family and a ligand for the orphan IL-1 family receptor ST2. The IL-33 induces T helper 2-type inflammatory responses and is considered to play a crucial rule in allergic inflammations, such as asthma and atopic dermatitis. However, the role of IL-33 and its receptor ST2 in allergic rhinitis remains unknown. OBJECTIVE We investigated expression of IL-33 and ST2 in the nasal epithelium of patients with allergic rhinitis and the mechanisms of the production of cytokines/chemokines induced by treatment with IL-33 using normal human nasal epithelial cells (HNECs) in vitro. METHODS Expression of IL-33 and ST2 in normal and allergic rhinitis nasal mucosa was evaluated by reverse transcription- and real-time polymerase chain reactions and immunohistochemical methods. The IL-33 in serum, and IL-8 and GM-CSF were measured by ELISA. For in vitro experiments, HNECs in primary culture were used. RESULTS The IL-33 levels in the sera of patients with allergic rhinitis were significantly higher than that in normal controls. Expression of IL-33 and ST2 was significantly elevated in the epithelium from patients with allergic rhinitis. The IL-33 mRNA in HNECs in vitro was significantly induced by treatment with IFN-γ and the toll-like receptor 9 ligand ODN2006. The IL-33-induced production of IL-8 and GM-CSF from HNECs in vitro was significantly suppressed by corticosteroid treatment and distinct signal transduction inhibitors of ERK, p38 MAPK, JNK, NF-κB and epidermal growth factor receptor. CONCLUSIONS AND CLINICAL RELEVANCE The IL-33 and its receptor ST2 play important roles in allergic rhinitis. The IL-33-mediated inflammatory responses via ST2 are regulated by distinct signalling pathways in HNECs and the IL-33/ST2 pathway may provide new therapeutic targets for allergic rhinitis.

Abstract
BACKGROUND High-mobility group box 1 (HMGB1) is a monocyte-derived late-acting inflammatory mediator, which is released in conditions such as shock, tissue injury and endotoxin-induced lethality. In this study, we determined the plasma and hepatic tissue levels of HMGB1 in patients with acute liver failure (ALF). PATIENTS AND METHODS We determined the plasma levels of HMGB1 and aspartate aminotransferase (AST) in 7 healthy volunteers (HVs), 40 patients with liver cirrhosis (LC), 37 patients with chronic hepatitis (CH), 18 patients with severe acute hepatitis (AH), and 14 patients with fulminant hepatitis (FH). The 14 patients with FH were divided into two subgroups depending upon the history of plasma exchange (PE) before their plasma sample collection. The hepatic levels of HMGB1 were measured in tissue samples from 3 patients with FH who underwent living-donor liver transplantation and from 3 healthy living donors. Hepatic tissue samples were also subjected to immunohistochemical examination for HMGB1. RESULTS The plasma levels of HMGB1 (ng/ml) were higher in patients with liver diseases, especially in FH patients with no history of PE, than in HVs (0.3 ± 0.3 in HVs, 4.0 ± 2.0 in LC, 5.2 ± 2.6 in CH, 8.6 ± 4.8 in severe AH, 7.8 ± 2.7 in FH with a history of PE, and 12.5 ± 2.6 in FH with no history of PE, p < 0.05 in each comparison). There was a strong and statistically significant relationship between the mean plasma HMGB1 level and the logarithm of the mean AST level (R = 0.900, p < 0.05). The hepatic tissue levels of HMGB1 (ng/mg tissue protein) were lower in patients with FH than in healthy donors (539 ± 116 in FH vs. 874 ± 81 in healthy donors, p < 0.05). Immunohistochemical staining for HMGB1 was strong and clear in the nuclei of hepatocytes in liver sections from healthy donors, but little staining in either nuclei or cytoplasm was evident in specimens from patients with FH. CONCLUSION We confirmed that plasma HMGB1 levels were increased in patients with ALF. Based on a comparison between HMGB1 contents in normal and ALF livers, it is very likely that HMGB1 is released from injured liver tissue.

Abstract
FeRh thin films were irradiated with a 10 MeV iodine ion microbeam to produce micrometre-scale ferromagnetic microstructures by modifying the local magnetic character from antiferromagnetism to ferromagnetism using ion-microbeam irradiation. Two-dimensional magnetic dot arrays of dimensions ∼2 µm × 4 µm as well as 10 µm × 10 µm were successfully produced on the FeRh surface, which was confirmed by magnetic force microscopy (MFM). The results of photoemission electron microscopy (PEEM) combined with X-ray magnetic circular dichroism reveal that the easy axis of the magnetization of the ion-beam-irradiated ferromagnetism in the FeRh thin films lies in the film planes along the <001> direction of the MgO substrates.

Abstract
AIMS The study aimed to combine a metagenomics approach with complementary genetics to identify novel bacterial genes with orthologous functions, with the identification of novel RNase H genes as a test case. METHODS AND RESULTS A metagenomic DNA library was prepared from leaf-and-branch compost and used to screen for the RNase H genes by their abilities to complement the temperature-sensitive growth phenotype of the rnhA mutant Escherichia coli strain MIC3001. Determination of the nucleotide sequences of the cloned DNA fragments allowed us to identify 12 different genes encoding type 1 RNases H. Eleven of them encode novel RNases H, which show 40-72% amino acid sequence identities to those available from database. One of them lacks a typical DEDD/E active-site motif, which is almost fully conserved in various RNases H. CONCLUSIONS Functional screening of environmental DNA without cultivation of microbes is a useful procedure to isolate novel RNase H genes. SIGNIFICANCE AND IMPACT OF THE STUDY One of the identified RNase H genes had no sequence similarity to a previously assumed conserved motif, suggesting multiple catalytic mechanisms exist. This test case illustrates that metagenomics combined with complementary genetics can identify novel genes that are orthologous without sequence similarity to those from cultivated bacteria.

Abstract
Fibromuscular dysplasia (FMD) is a non-atheromatous, non-inflammatory, multifocal segmental angiopathy. FMD is the most common cause of pediatric renovascular hypertension. Aneurysmal formation of the main renal artery and distal branches is a rare complication of FMD in infancy. We report an 8-month-old boy with FMD presenting with shock caused by sudden renal hemorrhage that necessitated removal of one kidney. A diagnosis of renovascular hypertension resulting from intimal type FMD with aneurysmal formation was made on the basis of the presence of hypertension, elevation of PRA and aldosterone activity, pathological findings and the results of renal angiography. Our findings suggest that it is therefore necessary to consider FMD with aneurysmal formation as a possible cause of hypertension and renal hemorrhage in infants.

Abstract
The TCF4 gene encodes a basic helix-loop-helix (bHLH) transcription factor which belongs to the family of E-proteins. E-proteins form homo- and heterodimers with other members of the HLH family and bind to the common DNA sequence called E-box. Haploinsufficiency of the TCF4 gene has been found to be associated with the Pitt-Hopkins syndrome (PTHS). PTHS is characterized by severe mental retardation, a wide mouth plus other distinctive facial features (fleshy lips, beaked nose, broad nasal bridge) and breathing abnormalities. Because of some phenotypical overlap with Angelman syndrome (AS), it has been suggested that PTHS be considered in its differential diagnosis. To explore this possibility, we screened 86 patients who were suspected of having AS. All the patients were negative for UBE3A testing, and 53 were known to be negative for methylation analysis. We identified two TCF4 mutations in this cohort. The p.S384Tfsx7 mutation lacks the bHLH domain. The p.R582P mutation lies within the bHLH domain in which seven other missense mutations have been reported. Both mutations most likely affect the critical function of the bHLH domain of the TCF4 protein. In summary, we found two TCF4 mutations in 86 patients (2%) suspected to have AS. Screening for mutations in this gene should be considered in patients who present with findings of AS but who have been negative for methylation and UBE3A testing.

Abstract
The genome of the hyperthermophilic archaeon Thermococcus kodakaraensis contains three genes encoding subtilisin-like serine proteases, Tk-1689, Tk-0076 and Tk-subtilisin. Of them, the structure and function of Tk-subtilisin have been extensively studied. To examine whether Tk-1689 is matured to an active form and functions as a hyperthermostable protease as is Tk-subtilisin, the gene encoding the Tk-1689 derivative without a putative N-terminal signal sequence, termed Pro-Tk-SP, was overexpressed in Escherichia coli. Pro-Tk-SP is composed of 640 amino acid residues and its molecular mass is 68.6 kDa. The recombinant protein was purified, however, as an active 44 kDa protease, termed Tk-SP, which lacks the N-terminal 113 and C-terminal 101 amino acid residues. This result suggests that Pro-Tk-SP consists of an N-terminal propeptide (Ala1-Ala113), a mature domain (Tk-SP, Val114-Val539) and a C-terminal propeptide (Asp540-Gly640). Like Tk-subtilisin, Tk-SP showed a broad substrate specificity and was highly thermostable. Its optimum temperature for activity was approximately 100 degrees C and its half-life at 100 degrees C was 100 min. It was fully resistant to treatment with 5% SDS, 8 M urea or 10% Triton X-100. However, unlike Tk-subtilisin and bacterial subtilisins, Tk-SP requires neither Ca2+ nor propeptide for folding. As a result, Tk-SP was fully active even in the presence of 10 mM EDTA. Thus, Tk-SP has a great advantage over other proteases in high resistance to heat, denaturants, detergents and chelating agents and therefore has great potential for application in biotechnology fields.
