INTRODUCTION Laparoscopic adjustable gastric banding (LAGB) is a method frequently used for treating obesity. It requires periodic band regulation associated with the need for port puncture. However, there is always a substantial risk of port rotation. AIM This publication presents a solution of the problem for a MiniMizer Extra band. MATERIAL AND METHODS One thousand one hundred and twenty...

BACKGROUND Vascular access devices placed into the central venous system are used routinely in the medical management of many patients. Catheter tip occlusion is a common complication of open-ended catheters, causing difficulty with blood withdrawal and infusion. This study evaluated whether a valved subcutaneous port system would have fewer associated complications than a standard nonvalved po...

In this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of Beris Fishery Port are studied. A series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. The outputs show that the nearshore directions of wave components are not perpendicular to the coast whic...

This research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. Previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and NOx in DI diesel engines. Since the most important engine design parameters, includi...

Background and objectives: The study was conducted with the aim to determine frequency and to assess the risk factors of portsite infection after elective laparoscopic cholecystectomy in low-risk patients at a tertiary care hospital of Kashmir.Design and Setting: Prospective.Patients and Methods : The study included 675 consecutive patients of port-site infection after elective laparoscopic cho...

Border ports play a substantial role in socio-economic exchanges, which reflect the diplomatic relations between neighboring countries. This paper maps and analyzes the evolution process of border ports in China since the 1930s, in terms of the spatial distribution, transport modes, cargo and flows of people. Four development modes of border ports and cities are summarized based on the function...

Objective: To evaluate the feasibility and safety of single-port laparoscopic hysterectomy comparing with multi-port laparoscopic hysterectomy in treatment of benign uterine diseases. Methods: Data were collected retrospectively by review of the medical records of 252 patients who underwent multi-port or single-port laparoscopic surgery for treatment of benign gynecologic diseases. Laparoscopy ...

BACKGROUND Postoperative radiation (PORT) is an option for non-small cell lung cancer (NSCLC) patients with resectable stage IIIA pathological N2 status (pN2). For patients with PORT, this study aims to investigate the impact of the exact number of positive lymph nodes (LNs) on overall survival (OS) and lung cancer-specific survival (LCSS). METHODS Within the Surveillance, Epidemiology, and E...

ion. For an abstraction, T (λx.t) is obtained by introducing an agent λ, and simply linking its right auxiliary port (called body port) to the root of T (t) and its left one (variable port) to the unique wire corresponding to x in T (t). If x does not appear in t, then the left port of the agent λ is linked to an agent (for erasure).
