Nanoliter flow rate is optimum for separation in capillary column liquid chromatography coupled with tandem mass spectrometry (muHPLC-MS/MS). In order to develop a high-performance automated proteome analysis system allowing direct injection sample containing detergents, the influence of void volume varied from 0 to 5 microL on the separation performance and proteomic coverage of sample injecti...

In order to understand how unburned hydrocarbons emerge from SI engines and, in particular, how nonfuel hydrocarbons are formed and oxidized, a new gas sampling technique has been developed. A sampling unit, based on a combination of techniques used in the Fast Flame Ionization Detector (FFID) and wall-mounted sampling valves, was designed and built to capture a sample of exhaust gas during a s...

PURPOSE Single-port laparoscopic splenectomy has been performed sporadically. The aim of this study is to assess our experience with single-port laparoscopic splenectomy compared to conventional multiport laparoscopic surgery for the usual treatment modality for various kinds of splenic disease. METHODS Between October 2008 to February 2014, 29 patients underwent single-port laparoscopic sple...

This paper details the optimisation of bulk material port handling systems through the use of a metaheuristic based approach. The effective management of port systems requires effective solutions for the design, operation and maintenance of these facilities. This has to be achieved through a reduction in financial costs, and an increase in the utilisation of equipment and other resources. The o...

OBJECTIVES With increasing surgeon experience, laparoscopic cholecystectomy has undergone many refinements including reduction in port number and size. Three-port laparoscopic cholecystectomy has been reported to be safe and feasible in various clinical trials. However, whether it offers any additional advantages remains controversial. This study reports a randomized trial that compared the cli...

Introduction: Radiation therapy is one of the methods of cancer treatment. In this method, it is necessary to avoid harming the healthy tissues of the patient which is in the vicinity of the target, as much as possible. Treatment verification is one of the most important steps of radiation therapy which has two usual methods, using Port film and EPID. The accuracy and precision of treatment in ...

OBJECTIVES Single-port surgery is a rapidly advancing technique in laparoscopic surgery. Currently, there is limited evidence on the learning curve and practicality of performing single-port laparoscopic cholecystectomy. METHODS Single-port cholecystectomy was performed on 20 consecutive patients for biliary dyskinesia, symptomatic cholelithiasis, or acute cholecystitis. The Tri-Port was plac...

Due to the increasing freight volumes passing via seaports checkpoints, and increasingly reported delays in customs clearance procedure, dry port, emerged as one kind of solution to such situation, instead of extending the port scale under limited land use. The place located with dry port (sometimes inland port) can solve not only the congestion embarrassment faced by connected seaport, but als...

Properly selected port sites for robot-assisted coronary artery bypass graft (CABG) improve the efficiency and quality of these procedures. In clinical practice, surgeons select port locations using external anatomic landmarks to estimate a patient's internal anatomy. This paper proposes an automated approach to port selection based on a preoperative image of the patient, thus avoiding the need...

BACKGROUND AND OBJECTIVE A recent FDA safety communication has discouraged the use of a power morcellator for myoma extraction and has called for a change in surgical techniques for myomectomy. The objective of this study was to compare surgical outcomes of laparoscopic single-, two-, and conventional three-port myomectomy and to evaluate the feasibility of contained manual morcellation for ute...
