Scattering Elimination in 2D IR Immune from Detector Artifacts.

Highly scattering samples, such as polymer droplets or solid-state powders, are difficult to study via coherent two-dimensional infrared (2D IR) spectroscopy. Previously, researchers have employed (quasi-) phase cycling, local-oscillator chopping, and polarization control to reduce scattering, but the latter method poses a limit on polarization-dependent measurements. Here, we present a method for Scattering Elimination Immune from Detector Artifacts (SEIFDA) in pump-probe 2D IR experiments.

Single-incision laparoscopic appendectomy: prospective case series at a single centre in Singapore.

Purpose: Laparoscopic appendectomy is widely accepted as a standard of care for acute appendicitis. Aim of our study is to assess the safety and feasibility of single-incision laparoscopic appendectomy (SILA) in our hospital setting.

Methods: From March to August 2010, 30 patients (21 male, 9 female) with mean age 30.

Single port laparoscopic liver resection for hepatocellular carcinoma: a preliminary report.

Single port laparoscopic surgery is an emerging technique, now commonly used in cholecystectomy. The experience of using this technique in liver resection for hepatocellular carcinoma is described in a series of 3 cases with single port laparoscopic liver resection performed during 2010. All patients were male aged 61 to 70 years, with several comorbidities.
