Comparing self-reported physical activity and sedentary time to objective fitness measures in a military cohort.

Objectives: Regular vigorous physical activity (PA) and high levels of physical fitness (PF) confer health benefits. Conversely, sedentary time is a risk factor for chronic illness, independent of PA. We evaluated associations between self-reported PA, sedentary time, and objective PF measures in military Service members.

Cameraless peritoneal entry in abdominal laparoscopy.

Background And Objectives: Despite significant advances in laparoscopic instrumentation and techniques, injury to intraabdominal structures remains a potentially serious complication of peritoneal access. Consensus on the best method to obtain peritoneal access is lacking. A safe technique that does not rely on direct visualization of the abdominal layers could shorten the learning curve for surgeons and potentially be adopted by other physicians for a variety of nonsurgical indications for peritoneal entry.

Interaction of water with three granular biopesticide formulations.

Two obstacles for biopesticide commercialization, long shelf life and reliable efficacy, are both affected by moisture availability. Three biopesticide delivery systems, TRE-G, PEC-G, and PESTA, were analyzed by dynamic vapor sorption analysis. The objective was to investigate the moisture sorption profile of each system in air at 25 degrees C and a relative humidity (RH) ranging from 0 to 90%.

The use of organic vapor sorption to determine low levels of amorphous content in processed pharmaceutical powders.

Organic dynamic vapor sorption (organic-DVS) was used to characterize amorphous content in known amorphous-crystalline mixtures of lactose and salbutamol sulfate. N-octane was chosen as an apolar probe and measurements were carried out by exposing mixtures of each sample to partial pressures 0-90% p/p(0). A linear relationship between amorphous content and n-octane partial pressure was observed for both lactose and salbutamol sulfate with R(2) values of 0.
