Diode lasers operating at 3 mu m in continuous wave mode at room temperature were fabricated using metamorphic molecular beam epitaxy. The laser heterostructures have a lattice constant 1.3-1.6% bigger than that of the GaSb substrates. The mismatch between the epi-structure and the substrate lattice constants was accommodated by a network of misfit dislocations confined within linearly composit...

Collagen is the most important structural protein in the animal kingdom and is responsible for the strength and integrity of many tissues like bone, teeth, cartilage and tendons. The mechanical properties of these tissues are determined by their hierarchical structure. However, how each level contributes to the overall properties of collagenous tissues, and how individual hierarchical levels in...

BACKGROUND Patients with diabetes who use insulin pumps [continuous subcutaneous insulin infusion (CSII)] undergo surgeries that require postoperative hospital admission. There are no defined guidelines for CSII perioperative use. METHODS This retrospective single-institution study identified type 1 and type 2 diabetes subjects by electronically searching 2005-2010 anesthesia preoperative ass...

BACKGROUND IUD is one of the safest and most widely used reversible methods of contraception. The purpose of this study was to determine IUD survival and reasons for early discontinuation in Bandar Abbas, south of Iran. METHODS Probability of IUD continuation rate and factors associated with discontinuation were assessed in a historical cohort study of 400 women records from March 2002 to Feb...

OBJECTIVE To assess the potential economic impact of new and more expensive antidepressants on the overall cost of treatment using cost-effectiveness analysis. METHOD For this analysis, a computerized decision tree of clinical practice was developed to model the 12-month treatment of moderate to severe depression in Canada. To complete the model, data were obtained from physician panels, the ...

OBJECTIVE The purpose of this study was to determine contraceptive continuation and repeat pregnancy rates in adolescents who are offered immediate postpartum etonogestrel implant (IPI) insertion. STUDY DESIGN Participants in an adolescent prenatal-postnatal program were enrolled in a prospective observational study of IPI insertion (IPI group, 171) vs other methods (control group, 225). Cont...
