Present distribution of the threatened killifish Aphanius fasciatus (Actinopterygii, Cyprinodontidae) in the Maltese Islands
A survey of the nine localities from which the threatened Killifish Aphanius fasciatus has been recorded in the Maltese Islands showed that large and thriving populations exist at Salina, at the Simar and Ghadira bird sanctuaries and in reservoirs at Marsa and Ghadira. The Simar and Ghadira populations are introduced and originate from a mixture of animals collected from Salina and Marsa. The provenance of the Marsa population is unknown but it is possibly autochthonous to the Marsa area. The Salina and possibly the Marsa populations seem to be the only remaining natural populations of this species in the Maltese Islands.peer-reviewe
A study of osteological and molecular differences in populations of Aphanius fasciatus Nardo 1827, from the Central Mediterranean (Teleostei, Cyprinodontidae)
Nine populations of Aphanius fasciatus Nardo,
1827 from the central Mediterranean were analysed by
examining the mitochondrial control region and the morphology
of the bony elements of the skull and vertebral
column, to study the degree of intraspecific differentiation
of A. fasciatus considering the level of isolation of the
different populations and the palaeogeographic history of
the central Mediterranean area. Both the molecular and
morphological analyses differentiate between the populations,
even if the topologies of the two trees are different.
Molecular and osteological investigations have consistently
demonstrated a well-supported differentiation of the
south-eastern Sicilian populations both within the same
group (Tigano et al. in Ital J Zool 71:1124–1133, 2004a;
Tigano et al. in Abstract volume XI European Congress of
Ichthyology, Tallin, Estonia, 2004b), and from the populations
from western Sicily, Tunisia and the island of Malta.
The molecular results show that the nine populations are
characterised by haplotypes that are well defined in relation
to a probably limited gene flow; while, as regards the
morphological data the differentiation found could be
explained in terms of the geographic isolation of the various
populations, although the influence of environmental
factors, which differ greatly between the various sites
where the populations live, cannot be ruled out.peer-reviewe
AIRO Breast Cancer Group Best Clinical Practice 2022 Update
Introduction: Breast cancer is the most common tumor in women and represents the leading cause of cancer death. Radiation therapy plays a key-role in the treatment of all breast cancer stages. Therefore, the adoption of evidence-based treatments is warranted, to ensure equity of access and standardization of care in clinical practice.Method: This national document on the highest evidence-based available data was developed and endorsed by the Italian Association of Radiation and Clinical Oncology (AIRO) Breast Cancer Group.We analyzed literature data regarding breast radiation therapy, using the SIGN (Scottish Intercollegiate Guidelines Network) methodology (www.sign.ac.uk). Updated findings from the literature were examined, including the highest levels of evidence (meta-analyses, randomized trials, and international guidelines) with a significant impact on clinical practice. The document deals with the role of radiation therapy in the treatment of primary breast cancer, local relapse, and metastatic disease, with focus on diagnosis, staging, local and systemic therapies, and follow up. Information is given on indications, techniques, total doses, and fractionations.Results: An extensive literature review from 2013 to 2021 was performed. The work was organized according to a general index of different topics and most chapters included individual questions and, when possible, synoptic and summary tables. Indications for radiation therapy in breast cancer were examined and integrated with other oncological treatments. A total of 50 questions were analyzed and answered.Four large areas of interest were investigated: (1) general strategy (multidisciplinary approach, contraindications, preliminary assessments, staging and management of patients with electronic devices); (2) systemic therapy (primary, adjuvant, in metastatic setting); (3) clinical aspects (invasive, non-invasive and micro-invasive carcinoma; particular situations such as young and elderly patients, breast cancer in males and cancer during pregnancy; follow up with possible acute and late toxicities; loco-regional relapse and metastatic disease); (4) technical aspects (radiation after conservative surgery or mastectomy, indications for boost, lymph node radiotherapy and partial breast irradiation).Appendixes about tumor bed boost and breast and lymph nodes contouring were implemented, including a dedicated web application. The scientific work was reviewed and validated by an expert group of breast cancer key-opinion leaders.Conclusions: Optimal breast cancer management requires a multidisciplinary approach sharing therapeutic strategies with the other involved specialists and the patient, within a coordinated and dedicated clinical path. In recent years, the high-level quality radiation therapy has shown a significant impact on local control and survival of breast cancer patients. Therefore, it is necessary to offer and guarantee accurate treatments according to the best standards of evidence-based medicine

Influence of Al<sub>2</sub>O<sub>3</sub> Overlayers on Intermolecular Interactions between Metal Oxide Bound Molecules
Intermolecular interactions on inorganic substrates can have a critical impact on the electrochemical and photophysical properties of the materials and subsequent performance in hybrid electronics. Critical to the intentional formation or inhibition of these processes is controlling interactions between molecules on a surface. In this report, we investigated the impact of surface loading and atomic-layer-deposited Al2O3 overlayers on the intermolecular interactions of a ZrO2-bound anthracene derivative as probed by the photophysical properties of the interface. While surface loading density had no impact on the absorption spectra of the films, there was an increase in excimer features with surface loading as observed by both emission and transient absorption. The addition of ALD overlayers of Al2O3 resulted in a decrease in excimer formation, but the emission and transient absorption spectra were still dominated by excimer features. These results suggest that ALD may provide a post-surface loading means of influencing such intermolecular interactions
