We have examined the role of the uvrC gene in UV excision repair by studying incision, excision, repair synthesis, and DNA strand reformation in Escherichia coli mutants made permeable to nucleoside triphosphates by toluene treatment. After irradiation, incisions occur normally in uvrC cells in the presence of nicotinamide mononucleotide (NMN), a ligase-blocking agent, but cannot be detected ot...

PURPOSE The laparoscopic appendectomy has become popular for the treatment of acute appendicitis. A single-incision laparoscopic appendectomy offers better cosmesis. We present the results of single-incision laparoscopic appendectomies in our hospital as initial experience. METHODS A single-incision laparoscopic appendectomy was performed in 75 patients at The Catholic University of Korea, Bu...

Background: Nipple-areola and skin sparing mastectomy (NASSM) is an accepted and sought after option for eligible patients, and the rate of women undergoing this operation continues to climb. The main advantage of the procedure is the ability utilize existing skin envelope and NAC for improved shape, fewer operations, and less psychological impact on patients. There are many possible incisions,...

PURPOSE To compare a transconjunctival single-plane sclerocorneal incision with 2 tiny conjunctival cuts at both ends and a clear corneal incision (CCI) in cataract surgery. SETTING Department of Ophthalmology, Institute of Clinical Medicine, University of Tsukuba, Ibaraki, Japan. METHODS Patients having routine cataract surgery were randomly divided into 2 groups based on incision type; th...

Tears of the triangular fibrocartilage complex (TFCC) often lead to chronic wrist pain. The commonly used 2-needle outside-in and inside-out suturing techniques require an extra incision to tie the sutures subcutaneously. We use a practical and cost-effective arthroscopic technique for treatment of peripheral Palmer type 1B TFCC tears using a hypodermic needle. This obviates the need for an add...

this work is a report 0/9 cases ofarcuate incision for correction 0/astigmatism, after penetrating keratoplasty. plannings were based ojj corneal topography, and the first operation was always arcuate incision alone. 11,e secondary plans were based on refractive errors. the mean of preoperative astigmatism was 6d with the range of5 to 9/). after arcuate incision a/the graft-host interface in th...

BACKGROUND Open reduction and internal fixation (ORIF) of the clavicle is a common procedure that has been shown to have improved outcomes over nonoperative treatment. Several incisions can be used to approach clavicle fractures, the decision of which is variable among surgeons. PURPOSE To compare patient satisfaction and subjective outcomes between patients with a longitudinal incision versu...
