Repair of aortico--left ventricular tunnel was accomplished for the first time in the neonatal period. The diagnosis was made with two-dimensional echocardiography. Repair was accomplished using an open-patch aortoplasty technique, which prevented valvular insufficiency, a significant problem in older patients in whom the repair has been attempted.

The excision repair of nondimer DNA damages induced in normal human skin fibroblasts exposed to the Mylar-filtered UV produced by a fluorescent sunlamp was investigated. This work was accomplished through the development of a modification of the bromodeoxyuridine photolysis assay that greatly increases the sensitivity of this assay. This enhancement in sensitivity was achieved through use of al...

OBJECTIVE We would like to share our experience of surgical repair of sinus venosus atrial septal defect (ASD) using a simple "transcaval repair technique." METHOD Between January 2007 and October 2010, 48 consecutive patients of sinus venosus ASD underwent surgical repair using transcaval repair technique at our institute. Their ages ranged from 5 to 15 years and male to female ratio was 1.6...

BACKGROUND Photoaged skin is characterized by coarse and fine wrinkles. The mechanism of wrinkle formation appears to involve changes to components of the dermal extracellular matrix. Topical treatment with all-trans retinoic acid (RA) can repair photoaged dermal matrix; this is regarded as the 'gold standard' against which repair agents are judged. To date, little is known regarding the abilit...

Base excision repair (BER) processes non-helix distorting lesions (e.g., uracils and gaps) and is composed of two subpathways that differ in the number of nucleotides (nts) incorporated during the DNA synthesis step: short patch (SP) repair incorporates 1 nt and long patch (LP) repair incorporates 2-12 nts. This choice for either LP or SP repair has not been analyzed in the context of nucleosom...

BACKGROUND Thousands of babies are born with congenital heart defects that require surgical repair involving a prosthetic implant. Lack of growth in prosthetic grafts is especially detrimental in pediatric surgery. Cell seeded biodegradable tissue engineered grafts are a novel solution to this problem. The purpose of the present study is to evaluate the feasibility of seeding human induced plur...

In this work, the charge dynamics characteristics of injection, transport and decay in porous and non-porous polytetrafluoroethylene (PTFE) film electrets were investigated by means of corona charging, isothermal and thermal stimulating surface-potential decay measurements. The results showed that the initial surface potential, whether positively or negatively charging, is much higher in non-po...

AIM The aim of this retrospective study is to compare the immediate and long-term postoperative outcomes of Lichtenstein and Kugel repair of inguinal hernia. METHODS From 1996 to 2006, 219 consecutive patients underwent inguinal hernia repair - 92 using a standard Lichtenstein repair and 127 with a Kugel patch. Patient characteristics, length of postoperative hospital stay and complication ra...

The base excision repair (BER) process removes base damage such as oxidation, alkylation or abasic sites. Two BER sub-pathways have been characterized using in vitro methods, and have been classified according to the length of the repair patch as either 'short-patch' BER (one nucleotide) or 'long-patch' BER (LP-BER; more than one nucleotide). To investigate the occurrence of LP-BER in vivo, we ...
