Directionally oriented peptide layers 1000 angstroms thick were constructed by polymerization on gold and indium-tin-oxide glass. A key feature is the use of an appropriately functionalized surface which initiation sites for are spaced at distances consistent with helical diameter peptide. Completely polyalanine polyphenylalanine have been constructed. The helicity layer was completely retained after heating 180 degrees C 7 days.

Even after successful Kasai portoenterostomy, progressive hepatic fibrosis in postoperative patients with biliary atresia (BA) can be associated portal hypertension and esophageal or gastric varices. Therefore, early diagnosis close follow-up of varices are important. We investigated the correlation between liver stiffness scores measured by FibroScan presence to examine usefulness as a preendoscopic screening test for varices.A total 49 81 children BA following operations were enrolled this...

The laparoscopic surgery for a choledochal cyst in children is technically challenging because of its high degree complexity despite possibility. In an attempt to overcome this weakness and facilitate the difficult steps minimally invasive resection children, we have performed robot-assisted cyst. aim study report lessons tips obtained from our experience children.From July 2008 October 2011, attempted resections 14 using da Vinci Robotic Surgical System(®) (Intuitive Surgical, Sunnyvale,...

Background. The shortage of donor organs is one the major barriers to transplantation worldwide. After success direct exchange (swap) program in Korea since 1991, we have developed a swap-around program. However, reports on long-term outcomes programs are scarce. Methods. From September 1995 2006, performed 1193 cases renal transplantation, including 398 from living-unrelated donors. donors included 129 and 269 nonexchange We compared with that program, examined merits limitations Results....

We aimed to describe abnormal platelet morphology and its clinical significance in infants who were diagnosed with arthrogryposis renal dysfunction cholestasis (ARC) syndrome. collected all of the cases ARC syndrome referred a single pediatric referral center. In patients, counts analysis performed peripheral blood smear specimens. Electron microscopy images obtained examine ultrastructure platelets. Over 12-year period, 12 identified. The sex ratio (male:female) was 1:1. median birth weight...

As if with a razor, single polypeptide chains that extend significantly above the bulk layer of polypeptides can be shaved off ala-nine and leucine aminopeptidases. In preparation tightly packed layers helical peptides, lengths peptide cannot controlled; enzymatic grooming process described here subsequent smoothing is possible, which important for potential applications these as waveguide materials.

Patients with biliary atresia (BA) treated Kasai portoenterostomy may later develop intractable cholangitis (IC) that is unresponsive to routine conservative treatment. It cause cirrhosis and eventually hepatic failure portal hypertension. Control of IC requires prolonged hospitalization for the administration intravenous antibiotics. To reduce period, we designed a home antibiotic treatment (HIVA) which can be administered after initial inpatient In this study, reviewed effects treatment.We...

This study evaluated the feasibility of a laparoscopic approach in children with generalized peritonitis secondary to perforated appendicitis.We retrospectively analyzed medical records patients who underwent appendectomy drainage for appendicitis at our hospital between September 2001 and April 2012. Laparoscopic outcomes were compared an open method appendicitis.Ninety-nine (LA) from appendicitis, 87 (OA) appendicitis. Wound infection was more common OA group (12.6%) than LA (4.0%;...

An extensive 35 × 20 cm sized full‐thickness abdominal wall defect was created after resection of aggressive fibromatosis in a 19‐year‐old male patient. Immediate reconstruction not possible due to prolonged operation time and resulting severe bowel edema. A silicone sheet with NPWT applied over the exposed viscera. After 1 week, substituted composite mesh. Then, bilateral free anterolateral thigh (ALT) flaps (30 12 25 sized) performed. Since there only single reliable recipient vessel...

Abstract A large number of criterion must be met for a material to practical value in the development wave guide optical switches. We have taken approach that optimal and permanent orientation is prime importance. addressed question alignment by developing techniques polymerization aminoacids form vertically oriented helices on gold surfaces. Using this approach, we been able grow layers alanine, methylalanine (ethylglycine), leucine, phenylalanine deposited silicon are 1 - 2000 Å thick....
