Purpose: We compared 2 suturing techniques for reattachment of the flexor digitorum profundus (FDP) via all-suture anchor.

Methods: We used fresh, matched-pair, cadaveric hands. We disarticulated the fingers at the proximal interphalangeal joints, preserving the proximal FDP. Read More

Purpose: The purpose of this study was to evaluate three different methods of attachment of continuous loop suspensory cortical preparation of all soft tissue central quad tendon grafts compared to a bone block control for anterior cruciate ligament reconstruction on construct displacement and load to failure.

Methods: Thirty-two cadaveric central quadriceps tendon (CQT) specimens were harvested, using three clinical techniques for graft fixation: cortical button alone (BTB EB), BTB cortical button with rip-stop suture (BTB RS), and continuous loop cortical button (BTB CL). A control group was also included that consisted of a bone block secured within testing clamps (BTB CON). Read More

Purpose: To compare stiffness, strain, and load to failure of 4- versus 5-strand hamstring anterior cruciate ligament reconstruction human tendon allografts with femoral suspensory and tibial interference screw fixation.

Methods: Allograft hamstring tendons were used to create 10 four-strand (4S) and 10 five-strand (5S) grafts. Grafts were fixed to a uniaxial electromechanical load system via a femoral cortical suspensory button and a bioabsorbable interference screw in bone analogue. Read More

Smoking is a life-threatening habit; that is why many nicotine-replacement therapies (NRTs), which include chewing gums, nicotine patches, lozenges, mouth sprays, inhalers and nasal sprays that are usually administered for 8-12 weeks, have been reported for smoking cessation. We report the fabrication of patches comprising nanomicelles-in-coaxial nanofibers (NFs) for the transdermal delivery of varenicline (VAR) tartrate, a partial agonist of the α4β2 receptor subtype, for smoking cessation. The cores of the fabricated coaxial NF structures are composed of polyethylene oxide, VAR-loaded Pluronic F127 nanomicelles (NPs) and free VAR, while the shell consists of a blend of cellulose acetate (CA) and polycaprolactone (PCL) in a ratio of 1 : 9 (w/w) that incorporates 50% (wt%) free VAR.

Statement Of Problem: Information on the survival and mode of failure of endodontically treated incisors without a ferrule and restored without dowels is lacking.

Purpose: The purpose of this in vitro study was to compare the survival and failure mode of endodontically treated incisors without a ferrule and restored with bonded ceramic crowns and various composite resin foundation restorations without dowels with a control group with fiber dowels.

Material And Methods: Forty-five decoronated endodontically treated bovine incisors without ferrule were divided into 3 experimental groups and restored with different adhesive foundation restorations without dowel: nanohybrid composite resin (Nd), bulk-fill composite resin foundation restoration (NdB), and fiber-reinforced bulk-fill composite resin (NdFR).
