Correlation Between Doppler Echocardiography and Right Heart Catheterisation-Derived Systolic and Mean Pulmonary Artery Pressures: Determinants of Discrepancies Between the Two Methods.

Background: There is still controversy about whether transthoracic echocardiography (TTE) can provide reliable estimations of pulmonary artery pressures (PAP). The primary endpoint of this study was to evaluate the correlation between TTE and right heart catheterisation (RHC) in estimating systolic (SPAP) and mean (MPAP) pulmonary artery pressures.

Methods: Between January 2011 and December 2018, 141 consecutive patients (average age 63.

Impact of a terbinafine-florfenicol-betamethasone acetate otic gel on the quality of life of dogs with acute otitis externa and their owners.

Background: Treatment of canine otitis externa with owner-administered products can be difficult.

Objectives: To evaluate otic treatment administered by a veterinarian on quality of life (QoL) of dogs with otitis externa and their owners, and on clinical and cytology parameters of otitis; compared to an owner-administered treatment.

Animals: Fifty client-owned dogs randomly randomized into two groups and treated for 2 weeks.

Efficacy and duration of action of oral fluralaner and spot-on moxidectin/imidacloprid in cats infested with Lynxacarus radovskyi.

Background: Lynxacarus radovskyi has been observed in cats in Malaysia; previously treatment with fipronil and moxidectin/imidacloprid spot-on has been described.

Objectives: To compare the efficacy of two spot-on treatments of moxidectin/imidacloprid, two weeks apart to a single oral dose of fluralaner against Lynxacarus radovskyi and evaluate time to re-infestation.

Methods: Thirty cats were assigned to three groups of ten cats each.

Efficacy of an ethanol/guar/triclosan/glycerine gel on bacteria and yeast loads in canine pododermatitis: a pilot study.

Objectives: To assess efficacy of a gel compound containing guar, glycerine, triclosan and ethanol (Pawcare®, JOKER Technologies, Kerzers, Switzerland) in decreasing bacterial and yeast loads on the paws of dogs with erythematous, greasy and/or malodorous pododermatitis.

Methods: In 20 dogs, each with at least two affected paws, semiquantitative Malassezia species counts were performed on 10 oil-immersion fields (range: 0 to 30) from acetate tapes pressed on the palmar/plantar surface of one paw. Half of the area was sampled before and the other half immediately after the application of Pawcare(®) .

Comparison of FEDESI and SCORFAD scoring systems for the evaluation of skin lesions in allergic cats.

Background: Feline Dermatitis Extent and Severity Index (FeDESI) and Scoring Feline Allergic Dermatitis (SCORFAD) are two different scoring systems for the evaluation of feline allergic dermatitis.

Objectives: To evaluate the correlation between FeDESI and SCORFAD and pruritus.

Animals And Methods: The dermatological lesions of 32 cats affected by feline allergic dermatitis were evaluated with both FeDESI and SCORFAD before treatment and once monthly during treatment where ciclosporin was administered at 7 mg/kg orally once daily for 1 month then tapered, when possible, in the subsequent 2 months.

Extramedullary Plasmacytoma of the Larynx Treated by a Surgical Endoscopic Approach and Radiotherapy.

Extramedullary plasmacytoma (EMP) is a rare variant of plasma cell myeloma that affects soft tissues. The head and neck region are the most affected sites, although others have also been described. Herein we report an uncommon case of EMP of the larynx in a 65-year-old male who presented with a history of progressive dysphonia and hoarseness.

Juvenile nasopharyngeal angiofibroma: comparison between endoscopic and open operative approaches.

Background And Aim: Juvenile nasopharyngeal angiofibroma (JNA) is a rare vascular and fibrous tumor that most commonly affects males in prepuberal and adolescent age. Traditionally, these tumors have been removed, after selective embolization, with the open surgical approach (degloving), but the interest in the endoscopic resection, especially for small tumors, has increased in recent years. To present our experience of JNA management, comparing the endoscopic approach and open/combined approach.

Study of socio-economic characteristics, diagnosis and outcome of women participating or not participating in mammogram screening.

Background: Breast cancer is the most common cancer and the leading cause of cancer death in women. Early detection is essential to reduce cancer mortality. Studying participation in an organised breast cancer screening program is important in order to evaluate the program effectiveness.

Diacylglycerol kinase alpha mediates HGF-induced Rac activation and membrane ruffling by regulating atypical PKC and RhoGDI.

Diacylglycerol kinases (DGKs) convert diacylglycerol (DAG) into phosphatidic acid (PA), acting as molecular switches between DAG- and PA-mediated signaling. We previously showed that Src-dependent activation and plasma membrane recruitment of DGKalpha are required for growth-factor-induced cell migration and ruffling, through the control of Rac small-GTPase activation and plasma membrane localization. Herein we unveil a signaling pathway through which DGKalpha coordinates the localization of Rac.

Activation of diacylglycerol kinase alpha is required for VEGF-induced angiogenic signaling in vitro.

Vascular endothelial growth factor-A (VEGF-A) promotes angiogenesis by stimulating migration, proliferation and organization of endothelium, through the activation of signaling pathways involving Src tyrosine kinase. As we had previously shown that Src-mediated activation of diacylglycerol kinase-alpha (Dgk-alpha) is required for hepatocytes growth factor-stimulated cell migration, we asked whether Dgk-alpha is involved in the transduction of angiogenic signaling. In PAE-KDR cells, an endothelial-derived cell line expressing VEGFR-2, VEGF-A165, stimulates the enzymatic activity of Dgk-alpha: activation is inhibited by R59949, an isoform-specific Dgk inhibitor, and is dependent on Src tyrosine kinase, with which Dgk-alpha forms a complex.

Ghrelin and des-acyl ghrelin inhibit cell death in cardiomyocytes and endothelial cells through ERK1/2 and PI 3-kinase/AKT.

Ghrelin is an acyl-peptide gastric hormone acting on the pituitary and hypothalamus to stimulate growth hormone (GH) release, adiposity, and appetite. Ghrelin endocrine activities are entirely dependent on its acylation and are mediated by GH secretagogue (GHS) receptor (GHSR)-1a, a G protein-coupled receptor mostly expressed in the pituitary and hypothalamus, previously identified as the receptor for a group of synthetic molecules featuring GH secretagogue (GHS) activity. Des-acyl ghrelin, which is far more abundant than ghrelin, does not bind GHSR-1a, is devoid of any endocrine activity, and its function is currently unknown.

Src-mediated activation of alpha-diacylglycerol kinase is required for hepatocyte growth factor-induced cell motility.

Diacylglycerol kinases are involved in cell signaling, either as regulators of diacylglycerol levels or as intracellular signal-generating enzymes. However, neither their role in signal transduction nor their biochemical regulation has been elucidated. Hepatocyte growth factor (HGF), upon binding to its tyrosine kinase receptor, activates multiple signaling pathways stimulating cell motility, scattering, proliferation and branching morphogenesis.
