Correlation of Dielectric Properties and Vibrational Spectra of Composite PVDF/Salt Fibers.

Nitride salts were added to polyvinylidene fluoride fibers and then the fiber mats were prepared by electrospinning. An experimental investigation of the structure was provided by Raman, FTIR, SEM, and XRD. The phase ratio of the polymer was studied both theoretically and experimentally in connection with the addition of the hydrates Mg(NO), Ca(NO), and Zn(NO) salts.

Posterior Capsule Reconstruction with Polypropylene Mesh After Total Hip Arthroplasty.

Instability remains a challenge after total hip arthroplasty (THA). We have previously utilized a monofilament polypropylene mesh to reconstruct the posterior capsule for unstable THA. This study identified 24 hips that underwent mesh reconstruction of the posterior capsule for instability.

Surgical automation reduces operating time while maintaining accuracy for direct anterior total hip arthroplasty.

Objective: Investigate the efficiency/accuracy of surgical automation versus manual component implantation in DA THA.

Methods: Retrospective review of 111 hips: 51 hips via automation and 60 hips via manual technique for DA THA.

Results: OR time averaged 8 min faster in the Automated group, compared to Manual group ( = 0.

Financial impact of removal of total knee arthroplasty from the inpatient-only list for a physician-owned BPCI program.

Objective: Assessing financial effects of removal of TKA from CMS inpatient-only list on physician-owned bundles.

Methods: We determined whether Medicare TKAs remained inpatient, versus changed to observational. We used CMS data to determine savings.

Leukocyte and plasma activation profiles in chronically transfused patients with a history of allergic reactions.

Background: Allergic transfusion reactions are drawbacks to the benefits of transfusion. Classically, allergic transfusion reactions depend on histamine release from mast cells or basophils, but other leukocyte subsets may also be important. Thus, we propose to better define the exact leukocyte subsets involved in allergic transfusion reactions.

A silk-based encapsulation platform for pancreatic islet transplantation improves islet function in vivo.

The success of pancreatic islet (PI) transplantation is challenged by PI functional damage during the peritransplantation period. A silk-based encapsulation platform including mesenchymal stromal cells (MSCs) was evaluated for islet cell delivery in vivo. Islet equivalents (IEQs) were transplanted into the epididymal fat pads of mice with streptozotocin-induced diabetes.
