Double-bundle anterior cruciate ligament reconstruction using autologous hamstrings with LARS augmentation demonstrates comparable outcomes to hamstrings alone, without evidence of synovitis or early osteoarthritis.

Purpose: To compare the clinical and radiological outcomes in patients undergoing anterior cruciate ligament reconstruction (ACLR) with, or without, LARS augmentation.

Methods: One-hundred and thirty-six patients that underwent double-bundle ACLR with (DB Hams/LARS, n = 67), or without (DB Hams, n = 69), LARS augmentation, were assessed clinically and with Magnetic Resonance Imaging (MRI) at a minimum of 7-years post-surgery. Patients were assessed via patient-reported outcome measures (PROMs), KT-1000 (laxity), isokinetic knee extensor and flexor strength and a 4-hop test battery.

A comparison of XRFS and ICP-OES methods for soil trace metal analyses in a mining impacted agricultural watershed.

Field portable X-ray fluorescence spectroscopy (XRFS) has become increasingly prevalent for in situ detection of trace metals, as it is both rapid and cost effective. The accuracy of in situ XRFS analyses has been questioned due to possible interferences from elevated soil moisture and organic content. In this study, three metal analysis protocols (Cd, Pb, Zn) were compared for surface soil samples collected near the Tar Creek Superfund Site in northeastern Oklahoma.

Metals retention in a net alkaline mine drainage impacted stream due to the colonization of the North American Beaver (Castor canadensis).

This study investigated two aspects of Castor canadensis (North American Beaver) colonization on a net alkaline mine drainage impacted tributary to Tar Creek (Ottawa County, OK, USA). Specifically, the retention of metals due to the presence of beaver dams, and metals contamination of sediments due to long-term loading, were examined. The Unnamed Tributary (UT) has been impacted by two mine drainage sources since at least 1979, with Cd, Fe, Pb, and Zn being the primary metals of concern.

Enhancing coping skills for persons with cancer utilizing mastery enhancement: a pilot randomized clinical trial.

The purpose of this project was to develop a short-term, theory-based intervention for patients with self-reported limited self-efficacy to perform coping behaviors. Cancer patients with low coping self-efficacy were randomly assigned to a treatment (N = 66) or control condition (N = 68). The treatment, Mastery Enhancement Therapy, was based on self-regulation and self-efficacy theories.

Characterization of trace metal removal products in vertical flow bioreactor substrates at the Mayer Ranch Passive Treatment System in the Tar Creek Superfund Site.

A passive treatment system (PTS), including two parallel vertical flow bioreactors (VFBR), was constructed in 2008 for the treatment of unabated net-alkaline ferruginous mine drainage in the Tar Creek Superfund Site in northeastern Oklahoma. Water quality data collected since the PTS began operation indicate significant removal of trace metals in the VFBR. Results of a sequential extraction procedure (SEP) performed on substrate samples showed that the majority of Cd, Co, Fe, Ni, Pb, and Zn were retained in the refractory organic/sulfide fraction.
