Respiratory epithelium exposed to sulfur dioxide--functional and ultrastructural alterations.

1995

The value of morphological investigations of airway mucosa should be compared to a functional method when estimating the toxicity of airborne pollutants. In 34 guinea pig tracheas, mucociliary activity was measured using a modified light beam reflex method before and following exposure to sulfur dioxide for 30 minutes in concentrations ranging between 7.5 and 37.5 mg/m3. Exposure to air served as a control. Simultaneously, specimens were taken for light and electron microscopy. Mucociliary activity decreased from 8.4 +/- 2.9 Hz (control exposure) to 4.0 +/- 2.9 Hz following exposure to 7.5 mg/m3, to 3.4 +/- 2.7 Hz at 15 mg/m3 sulfur dioxide, to 1.8 +/- 2.2 Hz at 22.5 mg/m3 sulfur dioxide, t…

Status of Recombinant Factor VIII Concentrate Treatment for Hemophilia A in Italy: Characteristics and Clinical Benefits

2019

The current interest in recombinant factor VIII (rFVIII) products stems from the fact that they offer a technological solution to prolonging the half-life of and reducing the risk of formation of alloantibodies (inhibitors) against FVIII in treated patients with hemophilia A (HA). The Italian health care system has authorized the use of a wide range of rFVIII concentrates of the first, second, and third generation, as well as new innovative rFVIII preparates with an extended half-life (EHL) (Kogenate FS®-Bayer, belonging to the second generation and replaced since 2017 by a product consisting of the same modified molecule; because it is only available until the end of the current year, it w…

Aspetti economici della produzione dell'arancia bionda in biologico

2009

The traditional function of Agriculture to produce food, today is substituted by multifunctional role in which the farm businessman becomes protagonist of territorial management an environmental preservation. Besides, the consumers orient increasingly their choices towards products obtained by a low land''s exploitation. The aim of paper is to highlight the technical bonds and the opportunities of organic orange cultivation. The study has regarded a sample of conventional an organic orange farms locaded in the Ribera area (AG), that is well-known for the cultivation of blonde orange. Microeconomic unalysis, through determination of production costs end principal economic parameters, has sho…

PROVE DI LOTTA A CERATITIS CAPITATA CON IL METODO "ATTRACT AND KILL" IN ARANCETI A MATURAZIONE PRECOCE

2011

La lotta alla mosca mediterranea della frutta, Ceratitis capitata (Wiedemann), nei frutteti biologici è considerata così problematica che il Reg. CE 889/08 ammette, soltanto per sfuggire agli attacchi di questo dittero tefritide, lo sverdimento degli agrumi con etilene e l'uso di due piretroidi, deltametrina e lambda-cialotrina, soltanto all'interno di trappole, in questo caso ammessi anche per la lotta a Bactrocera oleae (Rossi). Negli anni 2009 e 2010, in un aranceto biologico a maturazione precoce (cv Navelina) sito nel territorio di Sciacca (AG), sono state realizzate prove di lotta a C. capitata, utilizzando dispositivi sperimentali della ditta Agrisense denominati Magnet Med. Il dispo…

Thermal adaptation and physiological responses to environmental stress in tunicates

2017

Understanding the multifaceted nature of environmental fluctuations is crucial to predicting the physiological adjustments utilised by organisms in resisting or adapting to changes over time. Here we investigate the effects of 2 environmental stressors on tunicates, whose fitness can have important repercussions on the quality of habitat. Specifically, we report respiration rate (RR), clearance rate (CR), and assimilation efficiency (AE) of the ascidian Styela plicata in response to a range of temperatures and varying food availability. Temperature-dependent RR was observed only within a portion of the thermal window of the species. Significant differences in clearance rates were detected a…

An energy budget for the subtidal bivalve Modiolus barbatus (Mollusca) at different temperatures

2011

Clearance rates, respiration rates and food absorption efficiencies of the commercially interesting subtidal bivalve Modiolus barbatus were measured at different temperatures under laboratory conditions and scope for growth calculated. Clearance rates were highest at temperatures from 20 °C to 28 °C, whereas respiration rate was maximal at 9 °C and minimal at 26 °C. Highest mean values of absorbed energy occurred at 20 °C and 26 °C. Scope for growth trend had negative values at 9 °C, 15 °C and 28 °C and positive values at temperatures 20 °C and 26 °C. The profitable thermal window for M. barbatus to have energy sufficient for growth and reproduction corresponded to <5 months per year. Seawa…

Effect of the presence of the shore crab, Carcinus maenas, on the burrowing behaviour and clearance rate of the common cockle, Cerastoderma edule

2011

Bivalves demonstrate various morphological and behavioural adaptations to reduce the risk of being attacked by predators. This paper examines how the presence of the crab Carcinus maenas (L.), a natural predator of the cockle Cerastoderma edule (L.), affects its burrowing depth and clearance or feeding rate. Cockles were placed in experimental tanks and treated with three levels of predatory disturbance: (1) unfed crab loose inside the tank, (2) unfed crab inside a cage suspended in the water column and (3) no crab present. Cockles’ burrowing depth was measured in two sediment types: mud and sand. Cockles burrowed more deeply in treatments with no crabs. Burrowing depth in sand was signific…

Effect of salinity and temperature on feeding physiology and scope for growth of an invasive species (Brachidontes pharaonis - MOLLUSCA: BIVALVIA) wi…

2008

Abstract The Indo-Pacific mytilid Brachidontes pharaonis (Bivalvia, Fischer 1870) offers an excellent model for the study of “Lessepsian migration” and the successive colonization at new Mediterranean locations. This species in out competing indigenous bivalves is particularly well adapted to Mediterranean conditions and this is likely due to biological characteristics and physio-ecological plasticity. In the present paper, we report on clearance rate (CR), respiration rate (RR) and Scope for Growth (SFG) of B. pharaonis collected from a Western Sicilian pond (Southern Tyrrhenian, MED). Physiological variables were determined in response to a range of temperatures from 11 ° to 20 °C and a b…
