Five-Strand Hamstring Autograft Versus Quadruple Hamstring Autograft With Graft Diameters 8.0 Millimeters or More in Anterior Cruciate Ligament Reconstruction: Clinical Outcomes With a Minimum 2-Year Follow-Up.

Purpose: To compare the outcomes of 2 groups of patients undergoing anterior cruciate ligament (ACL) reconstruction: the first with a quadrupled semitendinosus gracilis (ST-G) autograft larger than 8 mm diameter and the second with a 5-strand ST-G autograft larger than 8 mm due to an insufficient diameter graft harvesting.

Methods: This was a retrospective study with 70 patients divided into 2 groups. Inclusion criteria included ACL ruptures of less than 3 months, ST-G ACL reconstructions, and final (4-strand or 5-strand) graft size larger than 8 mm.

Clinical and arthrometric outcomes of an anatomic outside-in single-bundle anterior cruciate ligament reconstruction using a retrodrill.

Background: The main option to perform an anatomic anterior cruciate ligament (ACL) reconstruction is the anteromedial portal (AMP) technique. It has several reported complications (iatrogenic chondral injury, posterior-wall blowout, short sockets, increased risk of injury to common peroneal nerve). In an attempt to avoid these complications the outside-in (OI) technique was revived with the addition of a retrodrill.

Accuracy of self-reported tobacco use in newly diagnosed cancer patients.

Purpose: Accurate identification of tobacco use is critical to implement evidence-based cessation treatments in cancer patients. The purpose of this study is to evaluate the accuracy of self-reported tobacco use in newly diagnosed cancer patients.

Methods: Tobacco use questionnaires and blood samples were collected from 233 newly diagnosed cancer patients (77 lung, 77 breast, and 79 prostate cancer).

Liquid-liquid domains in bilayers detected by wide angle X-ray scattering.

Wide angle x-ray scattering (WAXS) from oriented lipid multilayers is used to examine liquid-ordered (Lo)/liquid-disordered (Ld) phase coexistence in the system 1,2-dioleoyl-sn-glycero-3-phosphocholine/1,2-dipalmitoyl-sn-glycero-3-phosphocholine/cholesterol (DOPC/DPPC/Chol), which is a model for the outer leaflet of the animal cell plasma membrane. Using the method of analysis developed in the accompanying work, we find that two orientational distributions are necessary to fit the WAXS data at lower temperatures, whereas only one distribution is needed at temperatures higher than the miscibility transition temperature, T(mix) = 25-35 degrees C (for 1:1 DOPC/DPPC with 15%, 20%, 25%, and 30% Chol). We propose that the necessity for two distributions is a criterion for coexistence of Lo domains with a high S(x-ray) order parameter and Ld domains with a lower order parameter.
