It is well known that the enteric nervous system plays a key role in the generation of gastrointestinal peristaltic movements. Recently, the networks of interstitial cells of Cajal (ICC) have been found to be essential in the generation of spontaneous gastrointestinal movements. However, the role of ICC in the mechanisms involved in the generation of(More)
A new method for improving the timing yield of field-programmable gate array (FPGA) devices affected by random within-die variation is proposed. By selection of an appropriate configuration from a set of functionally equivalent configurations such that the critical paths do not share same circuit resources on the FPGA, both the average critical path delay(More)
DNA methylation at the C-5 position of cytosine (5mC) regulates gene expression and plays pivotal roles in various biological processes. The TET dioxygenases catalyze iterative oxidation of 5mC, leading to eventual demethylation. Inactivation of TET enzymes causes multistage developmental defects, impaired cell reprogramming, and hematopoietic malignancies.(More)
Variants in cullin 4B (CUL4B) are a known cause of syndromic X-linked intellectual disability. Here, we describe an additional 25 patients from 11 families with variants in CUL4B. We identified nine different novel variants in these families and confirmed the pathogenicity of all nontruncating variants. Neuroimaging data, available for 15 patients, showed(More)
In laparoscopic colorectal cancer (Lap-CRC) surgery, determination of a suitable mesentery division line and the appropriate degree of lymphadenectomy by tracing the blood supply is critical. We performed visualization of the lymph and blood flow by laparoscopic indocyanine green (ICG) fluorescence imaging (Lap-IGFI). ICG is injected into the submucosa near(More)
CUL4B, encoding a scaffold protein for the assembly of Cullin4B-Ring ubiquitin ligase (CRL4B) complexes, is frequently mutated in X-linked mental retardation (XLMR) patients. Here, we show that CUL4B, but not its paralog, CUL4A, targets WDR5, a core subunit of histone H3 lysine 4 (H3K4) methyltransferase complexes, for ubiquitylation and degradation in the(More)
AIM To evaluate the technical feasibility of laparoscopic lateral pelvic lymph node dissection (LPLD) following total mesorectal excision (TME) as prophylaxis for patients with advanced lower rectal cancer but no radiologic evidence of lymph node involvement. PATIENTS AND METHODS TME was performed on 30 patients with cT3N1-2M0 lower rectal cancer. LPLD(More)
Endoscopic submucosal dissection involves dissecting manipulation performed with tumors in an exposed condition for a long period of time. Thus, there is a risk for implantation of tumor cells. The objectives of this study were to examine exfoliated tumor cells after colorectal endoscopic submucosal dissection and to elucidate the effectiveness of(More)
We report a case of local recurrence of cancer after rectal endoscopic submucosal dissection (ESD). A 52-year-old male underwent a curative resection with ESD for rectal intramucosal cancer. Seventy-four months after ESD, surveillance colonoscopy showed an elevated lesion on the ESD scar, suspicious of a recurrence. The patient subsequently underwent a low(More)
Fbxw7 (also known as Sel-10, hCdc4 or hAgo) is the F-box protein component of a Skp1-Cul1-F-box protein (SCF) ubiquitin ligase. Fbxw7 contributes to the ubiquitin-mediated degradation of cyclin E, c-Myc, Aurora-A, Notch and c-Jun, all of which appear to function as cell-cycle promoters and oncogenic proteins. Loss of Fbxw7 results in elevated expression of(More)
