In this paper, we analyze the epicardial electromechanical response of an in silico cardiac ventricular wedge under both healthy and concentric hypertrophic conditions. This is achieved by taking into account the growth of the wedge thickness and the fiber dispersion that may follow. The electromechanical response is described in terms of some macroscopic measures, i.e. the action potential duration, the conduction velocity, the contractility and the contraction force. Our results suggest that growth reduces the action potential duration and conduction velocity, whilst it increases the contractility and contraction force, yielding an overall negative effect...

In order to assess dogs' personality changes during ontogeny, a cohort of 69 Border collies was followed up from six to 18-24 months. When the dogs were 6, 12, and 18-24 months old, their owners repeatedly filled in a dog personality questionnaire (DPQ), which yielded five personality factors divided into fifteen facets. All five DPQ factors were highly correlated between the three age classes, indicating that the dogs' personality remained consistent relative to other individuals. Nonetheless, at the group level significant changes with age were found for four of the five DPQ factors...

There is a growing number of applications demanding highly sensitive photodetectors in the mid-infrared. Thermal photodetectors, such as bolometers, have emerged as the technology of choice, because they do not need cooling. The performance of a bolometer is linked to its temperature coefficient of resistance (TCR, ∼2-4% K(-1) for state-of-the-art materials). Graphene is ideally suited for optoelectronic applications, with a variety of reported photodetectors ranging from visible to THz frequencies. For the mid-infrared, graphene-based detectors with TCRs ∼4-11% K(-1) have been demonstrated...

Tyag K Patel, James C Weis
Presented here is a rare cause of severe neck pain - acute longus colli calcific tendinitis - in a 54year old man who presented to the emergency department. The neck pain is due to inflammation caused by calcium hydroxyapatite crystal deposition in the tendons on the longus colli muscles. This is non-infectious. The gold standard for diagnosis is a CT neck which best shows the calcifications in the anterior vertebral column of C1-C4, where the tendons of these muscles insert bilaterally. Longus colli calcific tendinitis is not life-threatening and patients will make a full recovery after treatment with NSAIDs...

Longus colli tendinitis (LCT) is an acute inflammatory condition with symptoms typically consisting of acute neck pain and stiffness with or without dysphagia. Once more severe etiologies for these symptoms are ruled out, this self-limiting condition usually resolves spontaneously with nonsteroidal anti-inflammatory drugs and corticosteroids. We present a case of LCT that presented as acute neck pain, dysphagia, and odynophagia that rapidly resolved once diagnosed and treated with anti-inflammatory agents. Though exceedingly rare, LCT must be considered in the differential diagnosis of acute neck pain, dysphagia, and odynophagia when more common etiologies do not correlate with the clinical presentation...

OBJECTIVES: P-glycoprotein (P-gp) is responsible for the efflux of a broad variety of human and veterinary drugs. Canine P-gp polymorphisms alter drug disposition and toxicity, but their impact on the disposition of enantiomeric drugs is unknown. Using fexofenadine as a model compound, we developed and validated HPLC-fluorescence methods to determine the effect of P-gp on the disposition of fexofenadine and its enantiomers. METHODS: A chiral CD-Ph column was used for the separation of (R) and (S)-fexofenadine...

INTRODUCTION: Muscle fiber cross-sectional area (CSA) and proportion of different fiber types are important determinants of muscle function and overall metabolism. Genetic variation plays a substantial role in phenotypic variation of these traits, however, the underlying genes remain poorly understood. AIMS: This study aimed to map quantitative trait loci (QTL) affecting differences in soleus muscle fiber traits between the LG/J and SM/J mouse strains. METHODS: Fiber number, CSA, and proportion of oxidative type I fibers were assessed in the soleus of 334 genotyped male and female mice of the F34 generation of advanced intercross lines (AIL) derived from the LG/J and SM/J strains...

Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of gastroesophageal reflux in surgical clinics. Reflux can recur in between 3% and 30% of patients on whom antireflux surgery has been performed, and so revision surgery can be required due to recurrent symptoms or dysphagia in approximately 3% to 6% of the patients. The objective of this study is to evaluate the mechanism of recurrences after antireflux surgery and to share our results after revision surgery in recurrent cases...

BACKGROUND: The reliability of musculoskeletal diagnostic ultrasound imaging (MSK-DUSI) for the evaluation of neck musculature has been sparsely documented in the research literature. Until now, research has featured a limited number of subjects and only few studies have tested for both inter- and intra-reliability using appropriate methodology. METHODS: Four examiners conducted an inter- and intra-rater reliability and agreement study. Fifty females with and without neck pain (NP) between the ages of 20-70 were recruited from October 2014 to April 2015...

In this study were proposed different protocols for the treatment of mice naturally infected with Giardia muris. Male Swiss mice were divided into seven groups, with five animals each, in a blind, controlled, randomized by drawing lots and once-repeated experiment. Parasite detection and cure control were performed using the Faust method and search by trophozoites in the intestinal mucosa. Clinical parameters (weight, water and feed consumption, elimination of excreta, aspect of the fur and feces) were also evaluated...

Population genetic studies are efficient for inferring the invasion history based on a comparison of native and invasive populations, especially when conducted at species scale. An expected outcome in invasive populations is variability loss, and this is especially true in self-fertilizing species. We here focus on the self-fertilizing Pseudosuccinea columella, an invasive hermaphroditic freshwater snail that has greatly expanded its geographic distribution and that acts as intermediate host of Fasciola hepatica, the causative agent of human and veterinary fasciolosis...

Pectinate ligament dysplasia (PLD) is significantly associated with primary closed angle glaucoma (PCAG) in several dog breeds. Gonioscopy screening for PLD is advised in breeds in which PLD and PCAG are particularly prevalent in order that affected dogs may be eliminated from the breeding population. The Border Collie (BC), Hungarian Vizsla (HV) and Golden Retriever (GR) breeds are currently under investigation for PLD by the British Veterinary Association/Kennel Club/International Sheep Dog Society (BVA/KC/ISDS) Eye Scheme...
