OBJECTIVE To determine the outcome of various techniques of vascular repair in terms of repair related complications and limb salavagibility. METHODS From January 1999 to December 2005, this retrospective study was conducted in the Department of General Surgery, Lahore General Hospital, Lahore, Pakistan. The patients, who underwent various surgical interventions for extremity vascular trauma,...

BACKGROUND Several animal studies have raised concern about the risk for obstructive azoospermia owing to vasal fibrosis caused by the use of alloplastic mesh prosthesis in inguinal hernia repair. The aim of this study was to determine the prevalence of male infertility after bilateral mesh repair. METHODS In a prospective study, a questionnaire inquiring about involuntary childlessness, inve...

 Numerous “repair” mechanisms have been developed to improve the training data for supervised learning (SL) systems including feature selection, noise correction, and active learning. These repair mechanisms myopically repair instances as long the estimated system performance continues to improve. Such general repair can lead to unnecessary repairs and overfitting from repair which can lower s...

To analyze the relation between SNPs in DNA repair pathway-related genes and sensitivity of tumor radio-chemotherapy, 26 SNPs in 20 DNA repair genes were genotyped on 176 patients of NSCLC undertaking radio-chemotherapy treatment. In squamous cell carcinoma (SCC), as the rs2228000, rs2228001 (XPC), rs2273953 (TP73), rs2279744 (MDM2), rs2299939 (PTEN) and rs8178085, rs12334811 (DNA-PKcs) affecte...

Level of Repair Analysis (LORA) is a prescribed procedure for defence logistics support planning. For a complex engineering system containing perhaps thousands of assemblies, sub-assemblies, components, etc. organized into several levels of indenture and with a number of possible repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities to minimize over...

Background and Objectives Ventral hernia repair is one of the most commonly performed general surgery procedures, and minimally invasive approaches are increasingly preferred. The physiologic repair offered by the preperitoneal approach is favorable, with reduced complications, but it remains a technical challenge. The robotic platform allows for enhanced instrument flexibility and ease of oper...

The present investigation deals with a machine repair problem consisting of cold and warm standby machines. The machines are subject to breakdown and are repaired by the permanent repairman operating under N-policy. There is provision of one additional removable repairman who is called upon when the work load of failed machines crosses a certain threshold level and is removed as soon as the wor...

Embryos and juveniles in many organisms repair tissue injuries better than adults. In this issue, Shyh-Chang et al. find that postnatal activation of Lin28a, a gene typically active in embryonic development, promotes better than normal tissue repair in mice, including following ear and digit injuries.

For general exact repair regenerating codes, the optimal trade-offs between storage size and repair bandwith remain undetermined. Various outer bounds and partial results have been proposed. Using a simple chain rule argument we identify nonnegative differences between the functional repair and the exact repair outer bounds. One of the differences is then bounded from below by the repair data o...

This paper deals with the G/G/R machining system consisting of M operating machines as well as S cold standbys. The concepts of balking and reneging are incorporated which make our model more versatile to deal with real time systems. The broken-down machines are sent to repair facilities consisting of R permanent repairmen. The failure times and repair times are generally identical and independ...
