Solapamiento del nicho trófico en un área de cría en la costa portuguesa

2002

The diets and the trophic niche overlap between seven flatfish species were studied in a coastal nursery adjoining to the Tagus estuary (Portugal). Fish were sampled monthly, from March to November 1999, using a beach seine. Arnoglossus imperialis (Rafinesque, 1810), Arnoglossus laterna (Walbaum, 1792) and Arnoglossus thori Kyle, 1913, fed mainly on crustaceans. The diets of Buglossidium luteum (Risso, 1810) and Dicologoglossa cuneata (Moreau, 1881) were mainly composed of Bivalvia and Polychaeta, while for Scophthalmus rhombus (Linnaeus, 1758) the main food items were Mysidacea and Teleostei. The diet of Pegusa lascaris (Risso, 1810) was mainly composed by Cumacea, Bivalvia, Decapoda and A…

The diagnostic role of pathergy test in patients with Behçet's disease from the Western Europe.

2022

The aim of the study is to evaluate the frequency and features of positive pathergy test (PPT) in Italy, its role in the diagnosis of Behçet's disease (BD), and any association with other BD-related manifestations. 52 BD patients, 52 patients with axial spondyloarthritis (ax-SpA), and 26 healthy controls (HCs) underwent intradermal injection of normal saline and intradermal needle soaked with fresh self-saliva. The results of pathergy tests were statistically analysed in the light of demographic, clinical, and therapeutic features of subjects enrolled. Pathergy test performed with saline resulted always negative in all groups. Skin prick test using self-saliva resulted in the occurrence of …

Array CGH defined interstitial deletion on chromosome 14: a new case

2009

Interstitial deletions of the long arm of chromosome 14 are relatively rare. We report a 8.5-year-old girl with dysmorphic facial features and mental retardation associated with a de novo interstitial deletion of chromosome 14. The comparison between our patient and all published patients is reviewed. The genetic investigations have allowed us to define the critical chromosomal region and to start an accurate follow-up.

HELMINTH ASSEMBLAGES OF WHITEFISH (COREGONUS LAVARETUS) IN INTERCONNECTED LAKES: SIMILARITY AS A FUNCTION OF SPECIES SPECIFIC PARASITES AND GEOGRAPHI…

2004

This article examined the composition of parasite assemblages of whitefish (Coregonus lavaretus) in 8 interconnected lakes in northeastern Finland and evaluated the role of coregonid specific parasites and the geographical distance between populations in determining the similarity of the assemblages. Parasite assemblages were compared using the Jaccard qualitative similarity index and a quantitative similarity index and by incorporating the allogenic-autogenic species concept and the effects of 2 corresponding measures of geographical distance between the lakes. The majority of the parasite species found (10 of 14) were specific to salmonids. Similarity of assemblages of autogenic parasites…

Host–virus evolutionary dynamics with specialist and generalist infection strategies: Bifurcations, bistability, and chaos

2019

In this work, we have investigated the evolutionary dynamics of a generalist pathogen, e.g., a virus population, that evolves toward specialization in an environment with multiple host types. We have particularly explored under which conditions generalist viral strains may rise in frequency and coexist with specialist strains or even dominate the population. By means of a nonlinear mathematical model and bifurcation analysis, we have determined the theoretical conditions for stability of nine identified equilibria and provided biological interpretation in terms of the infection rates for the viral specialist and generalist strains. By means of a stability diagram, we identified stable fixed…

Adiponectin, resistin and leptin in paediatric chronic renal failure: Correlation with auxological and endocrine profiles

2013

Introduction: Chronic renal failure (CRF) compromises nutrition, growth, puberty, glycometabolic homeostasis, and adipokine secretion (i.e. adiponectin, resistin, and leptin). Adipokines play a role in the clinical outcome, but data in paediatric patients is scant. Aim: To evaluate the link between kidney function, adiponectin, resistin, leptin, hormonal status, nutritional state and late outcome of CRF children. Materials and methods: We studied leptin, adiponectin and resistin levels in 31 CRF patients (19 males, 12 females, aged 12.1 ± 4.47 years) managed conservatively, and 30 healthy age- and gender-matched controls. Clinical, auxological, biochemical, hormonal data, glucose and insuli…

Post-chemotherapy physical fitness level on children with diagnosis of leukemia: results of a pilot study

2012

Introduction: Children with diagnosis of leukemia are at risk for developing neuromuscular and musculoskeletal complications such as decreased muscle strength, impaired gross and fine motor performance, decreased energy expenditure, osteonecrosis, and osteoporosis. These secondary complications due to the medical interventions may lead to activity limitations and participation restrictions in daily life experiences. However, few Authors suggest that if children participate in an individualized physical therapy exercise program, these limitations may be prevented or at least reduced. We evaluated the level of physical fitness on children with diagnosis of leukemia (C-LK) during the post-chem…

COVID-19 temporally related multisystem inflammatory syndrome (MIS-C): an early window of opportunity is a good treatment strategy? The experience of…

2021

Introduction: Multi-system inflammatory syndrome in children (MISC) shows a presentation mimicking Kawasaki Disease (KD), Toxic Shock Syndrome (TSS), Macrophage Activation Syndrome (MAS). Furthermore, many children show respiratory or abdominal symptoms. Objectives: Intravenous immunoglobulin (IVIG) is recommended as first line treatment as in KD, followed by aspirin, steroids and, in IVIGresistant patients, IL-1 or IL-6 blocking agents. Methods: We describe a cohort of 16 Sicilian children (6M;10F; age:1.4-14 years), with MIS-C, with clinical features compatible with classical or incomplete KD, in some cases with MAS and/or TSS. Demographic, clinical, laboratory, echocardiographic and imag…

Homozygosity for a Mutation in the CYP11B2 Gene and GH Deficiency in a Child with Severe Growth Delay

2015

Background: Isolated hypoaldosteronism is an autosomal recessive inherited disorder of terminal aldosterone synthesis, leading to selective aldosterone deficiency. Two different biochemical forms of this disease have been described, called aldosterone synthase deficiency or corticosterone methyl oxydase, types 1 and 2. In type 1, there is no aldosterone synthase activity and the 18 hydroxycorticosterone (18 OHB) level is low, whereas in type 2, a residual activity of aldosterone synthase persists and 18 OHB is overproduced. Objective and hypotheses: Isolated aldosterone synthase deficiency should be considered in neonates and infants with failure to thrive and salt wasting. Normal levels of…
