Diagnosis and management of femoral head osteochondritis dissecans (OCD) in two dogs.

Patient 1 was seen for severe pelvic limb lameness and evaluated radiographically and via computed tomography. A diagnosis of femoral head osteochondritis dissecans was obtained. The diagnosis was confirmed arthroscopically and treated with flap removal and abrasion arthroplasty.

Internet-based survey on diagnosis and treatment recommendations for medial shoulder syndrome and instability in dogs.

Objective: The aim of this study was to document perceived frequency of medial shoulder syndrome and instability (MSS/MSI) among dogs, and preferred diagnostic and treatment options related to the condition, among American or European Colleges of Veterinary Surgeons (ACVS/ECVS) diplomates, American College of Veterinary Sports Medicine and Rehabilitation (ACVSMR) diplomates, and dual diplomates of ACVS/ECVS and ACVSMR (double-Boarded diplomates).

Procedure: An invitation to complete an online survey was sent to diplomates email listservs.

Results: The known response rate for the survey was 15.

Short-term outcomes of 43 dogs treated with arthroscopic suturing for meniscal tears associated with cranial cruciate ligament disease.

Objective: To describe short-term outcomes and complications in dogs receiving meniscal suturing and concurrent tibial plateau leveling osteotomy (TPLO) with or without augmentation with an extracapsular suture.

Study Design: Retrospective case series.

Animals: Forty-three client-owned dogs submitted for cruciate ligament disease.

Ex vivo evaluation of arthroscopically assisted shoulder stabilization in dogs using an intra-articular aiming device.

Objective: To evaluate the use of an intra-articular aiming device (IAD) for medial shoulder stabilization with a suture-toggle repair or an interference screw repair using bone anchors in dogs.

Study Design: Ex-vivo Study METHODS: Specimens were randomly divided into 2 groups (anchor and suture-toggle) with 10 shoulders each. Abduction angles were measured by goniometry prior to and following medial glenerohumeral ligament transection and after receiving arthroscopically assisted stabilization with either bone anchors or suture-toggle constructs.

Ex vivo mechanical properties of a 2.5-mm bone anchor for treatment of cranial cruciate ligament rupture in toy breed dogs.

Objective: To determine the mechanical pull-out properties of a 2.5-mm bone anchor implanted in ex vivo femurs of toy breed dogs and to determine whether there is a difference between knotted and knotless configurations.

Study Design: Experimental study.

Arthroscopic placement of a toggle rod to correct coxofemoral luxation in a dog.

Objective: To describe a minimally invasive toggle repair technique under arthroscopic guidance to correct a coxofemoral luxation in a canine.

Study Design: Case report ANIMALS: A 9-year-old, male (neutered) Alaskan husky.

Methods: Prior to surgery, the coxofemoral luxation was reduced in a closed fashion.

Extension of the source-sink potential (SSP) approach to multichannel quantum transport.

We present an extension of the single channel source-sink potential approach [F. Goyer, M. Ernzerhof, and M.

Molecular conductance obtained in terms of orbital densities and response functions.

Using the source-sink potential (SSP) approach recently developed in our group, we study electron transmission through molecular electronic devices (MEDs). Instead of considering the source-sink potentials exactly, we use a perturbative approach to find an expression for the transmission probability T(E) = 1 - absolute value(r(E))(2) that depends on the properties of the bare molecule. As a consequence, our approach is limited to weak molecule-contact coupling.

Loss of GIMAP5 (GTPase of immunity-associated nucleotide binding protein 5) impairs calcium signaling in rat T lymphocytes.

The recessive lyp allele, which harbors a defective gimap5 (GTPase of immunity-associated nucleotide binding protein 5) gene, causes spontaneous apoptosis of T lymphocytes in the biobreeding diabetes-prone strain of rats. Mechanisms underlying the pro-survival function of GIMAP5 remain unclear. In this study, we show that gimap5(lyp/lyp) T cells display diminished calcium flux in response to thapsigargin or signaling via the T cell antigen receptor.

Electron Transmission through Aromatic Molecules.

A prominent feature of aromatic compounds is the ring current that can be observed indirectly in nuclear magnetic resonance experiments. This current is generated by an external magnetic field. In molecular electronics, molecules serve as conductors, and they are connected to metallic contacts that act as electron sources and electron sinks.

Side-chain effects in molecular electronic devices.

We discuss the effect of an abundant structural element of molecules on the transmission probabilities of molecular electronic devices. We show that an attachment of side chains to a molecular conductor may lead to zero transmission probabilities. The gaps in the transmission-probability appear approximately at the eigenvalues of the isolated side chains, provided that the corresponding eigenstates are not localized away from the molecular conductor.

Approximate density functionals applied to molecular quantum dots.

Recently, molecular quantum dots (MQDs) have been investigated experimentally and found to exhibit the Kondo effect. The Kondo effect leads to an enhancement of the zero-voltage conductance. Here, we study a finite cluster model of a MQD by means of Kohn-Sham density functional theory.
