Development of octopus aquaculture Final Report FRDC Project No 2009/206

During the past four years, the marine aquaculture group at the WA Fisheries and Marine Research Laboratories (WAFMRL) in collaboration with Occoculture Pty Ltd (subsidiary of Fremantle Octopus) and as a part of the FRDC project ‘Octopus Aquaculture Development’, investigated the potential of octopus aquaculture in Western Australia. Hatchery methods were developed in an attempt to close the life cycle. Advanced systems, rearing and feeding protocols were established for ranching Octopus tetricus juveniles

Use of a comprehensive diagnostic algorithm for Anisakis allergy in a high seroprevalence Mediterranean setting

Background. Diagnosis of anisakis allergy (AA) is based on the skin prick test (SPT) and specific IgE (sIgE) determination. Anyway, false positivity cases are due to cross reactivity with numerous allergens. The aim of the study was to evaluate the reliability of a comprehensive diagnostic algorithm for the AA. Methods. An observational study was conducted on a sample of consecutive subjects accessing the allergology outpatient ambulatories of two hospitals located in Western Sicily. All the recruited outpatients were tested by Skin Prick Test performed using anisakis extracts by ALK-Abello (Madrid, Spain). Specific IgE dosage for anisakis extracts was then performed by using ImmunoCAP250 (Immunodiagnostics Uppsala, Sweden). Consequently, outpatients who tested positive to first line tests underwent sIgE testing for ascaris and tropomyosin. Lastly, outpatients positive to the first line were invited to be further tested by basophil activation test (BAT) by using Flow CAST kit and anisakis commercial extract (Buhlmann Laboratories AG, Schonenbuch, Switzerland), as confirmatory analysis. Results. One hundred and eleven outpatients with an anamnesis suggestive of sensitization to anisakis (AS) and 466 subjects with chronic urticaria (CU) were recruited in the study. Of these, 22 with AS and 41 with CU showed a sensitization to anisakis allergens. The diagnostic algorithm revealed that 8.8% of outpatients who tested positive to sIgE determination were affected by CU, while 82.5% of all the sIgE positivity was related to cross-reactivity. Overall, a genuine anisakis seroprevalence of 2.3% was documented. Within a sub-sample of 15 subjects with clinical symptoms related to AA, n. 8 showed a real positivity after BAT. A greater response to A. pegreffii allergens as compared to A. simplex was reported. Conclusions. Our preliminary findings support the high clinical specificity of BAT for AA diagnosis, suggesting implementing this method in a comprehensive diagnostic algorithm

QUBIC: The Q&U Bolometric Interferometer for Cosmology - A novel way to look at the polarized Cosmic Microwave Background

In this paper we describe QUBIC, an experiment that takes up the challenge posed by the detection of primordial gravitational waves with a novel approach, that combines the sensitivity of state-of-the art bolometric detectors with the systematic effects control typical of interferometers. The so-called "self-calibration" is a technique deeply rooted in the interferometric nature of the instrument and allows us to clean the measured data from instrumental effects. The first module of QUBIC is a dual band instrument (150 GHz and 220 GHz) that will be deployed in Argentina during the Fall 2018.Fil: Mennella, Aniello. University of Milan; ItaliaFil: Ade, P. A.

Nutritional and mineral composition of persimmon fruits (Diospyros kaki L.) from Central and Southern Italy

In this study, the nutritional and mineral composition of Diospyros kaki fruits from Apulia, Campania, Lazio, Sardinia and Sicily regions was evaluated. Dietary fiber, mineral, pectin, polyphenol, and protein contents were evaluated. Particularly high are the contents of the dietary fiber and pectins. The mineral elements profile was interesting due to its modest content of sodium and high potassium concentration. Protein amounts were in line with the quantities for this fruit. The total polyphenol content of the fruits analysed was very variable, interesting for the quantities found both total and gallic acid. The results obtained confirmed the nutritional value of this fruit even for special dietary regimens such as hypertension and heart diseases and the genuineness of its cultivation in Central-Southern Italy.

Molecular identification of Hysterothylacium spp. in fishes from the southern Mediterranean Sea (southern Italy)

Samples obtained from 11 teleost fish species collected in waters off of the Mediterranean coasts of Sicily, Italy, were examined for the presence of Hysterothylacium spp. larvae. In total, 3,017 fish samples were examined, and the larvae recovered were used in subsequent phylogenetic studies. Fifty-eight raphidascaridid parasitic nematodes were found in the examined fish, with prevalence values ranging from 0.2% in anchovies to 60% in forkbeard samples. Twenty-seven parasites were identified as Hysterothylacium fabri and Hysterothylacium aduncum by sequencing the following regions: the nuclear ribosomal internal transcribed spacer ( ITS) and the mitochondrial cytochrome c oxidase subunit II ( COXII). Two other larvae collected from Lophius piscatorius had very low identity scores, with ITS and COXII sequences reported in GenBank and high genetic distances (AY603539). Pairwise comparisons between the ITS region of the H. fabri isolated from fishes from Sicilian coastal waters and those isolated from the Mediterranean Sea, Turkey (KC852206), revealed genetic differences ranging from 0.015 to 0.018. Our H. aduncum samples had very low genetic differences to H. aduncum from the Adriatic Sea (KP979763, 0.00-0.003). The concatenated phylogenetic examination of the ITS- COXII sequences by using maximum likelihood analyses indicated 3 distinct clades supported by high bootstrap values. Further molecular identification and detailed morphological analyses are needed to clarify these results and confirm the diversity and relationships within Hysterothylacium
