BACKGROUND: Multiple sclerosis (MS) is an inflammatory demyelinating disease classically associated with axonal damage and loss; more recently, however, synaptic changes have been recognized as additional contributing factors. An anatomical area commonly affected in MS is the visual pathway; yet, changes other than those associated with inflammatory demyelination of the optic nerve, i.e., optic neuritis, have not been described in detail. METHODS: Adult mice were subjected to a diet containing cuprizone to mimic certain aspects of inflammatory demyelination as seen in MS...

Anatomically accurate and biophysically detailed bidomain models of the human heart have proven a powerful tool for gaining quantitative insight into the links between electrical sources in the myocardium and the concomitant current flow in the surrounding medium as they represent their relationship mechanistically based on first principles. Such models are increasingly considered as a clinical research tool with the perspective of being used, ultimately, as a complementary diagnostic modality. An important prerequisite in many clinical modeling applications is the ability of models to faithfully replicate potential maps and electrograms recorded from a given patient...

BACKGROUND: Patients with secondary unilateral cleft lip are regularly affected by serious nasal deformities especially of the alar and nasal floor. A large number of techniques for correction have been published, but symmetrical restoration of severe nasal deformation is difficult to achieve. We propose an innovative approach for anatomical restoration for this entity of nasal deformities to achieve long-term symmetrical appearance and muscular function. METHODS: A total of 68 patients with severe nasal deformity due to secondary unilateral cleft lip underwent reconstructive surgery using a double composite tissue Z-plasty technique for anatomical restoration of cartilage, muscle, and soft tissue layers...

Microscopic animals that live among and between sediment grains (meiobenthic metazoans) are key constituents of modern aquatic ecosystems, but are effectively absent from the fossil record. We describe an assemblage of microscopic fossil loriciferans (Ecdysozoa, Loricifera) from the late Cambrian Deadwood Formation of western Canada. The fossils share a characteristic head structure and minute adult body size (~300 μm) with modern loriciferans, indicating the early evolution and subsequent conservation of an obligate, permanently meiobenthic lifestyle...

Paraventricular thalamic nucleus (PVT) neurons receive hindbrain and hypothalamic inputs, and project to forebrain sites involved in reward and motivation function. The role of PVT in energy balance and reward control is however understudied. Given that PVT neurons express glucagon-like peptide-1 receptors (GLP-1R), which are critical to feeding and body weight control, we tested the hypothesis that PVT GLP-1R signaling contributes to food intake and reward inhibition. To assess the hypothesis, behavioral tests including chow and high-fat diet intake, meal patterns, conditioned place preference for high-fat food, cue-induced reinstatement of sucrose-seeking, and motivation to work for sucrose were employed following intra-PVT delivery of either GLP-1R agonist, exendin-4 (Ex4), or GLP-1R antagonist, exendin-9-39 (Ex9)...

PURPOSE: Carpal tunnel and cubital tunnel syndrome are the 2 most common upper-limb compressive neuropathies. However, whether the characteristics of patient populations undergoing surgery for these conditions are similar is unclear in terms of demographics and concomitant pathologies. Our null hypothesis was that there are no identifiable differences between these patient populations. METHODS: A retrospective cohort study was performed by billing system query using Common Procedural Terminology (CPT) codes for all patients who underwent open carpal tunnel release (CTR) (CPT code 64721) and/or open cubital tunnel surgery (CPT code 64718) by 1 of 4 hand surgeons from August 2008 to July 2013...

We analysed cancer risks in patients with urinary tract stones but some features of the generated results alarmed us about possible surveillance bias, which we describe in this report. We used nationwide Swedish hospital records to identify patients with urinary tract stones (N = 211,718) and cancer registration data for cancer patients for years 1987 to 2012. Standardized incidence ratios (SIRs) for cancer were calculated after the last medical contact for urinary tract stones. All cancers were increased after kidney (SIR 1...

Kinematic changes have been shown to accompany severe knee osteoarthritis, but no studies have analyzed early-stage osteoarthritic knee kinematics in the transverse plane during functional activities. The purpose of this study was to analyze kinematics of early-stage osteoarthritic knees using model registration techniques. Fifteen early-stage osteoarthritic knees from eight females with a mean age of 52 years old (range, 43-57years old) were involved in this study. A radiologist confirmed with plain radiographs that knees had Kellgren-Lawrence grade-1 or -2 arthritic changes...
