Adverse Events Related to Vaccination (VAEs): How to Manage the Further Doses of Immunization and Parents’ Hesitancy
This study supports the evidence that after vaccine‐related reactions, it is still possible to carry out the immunization protocol
Resilience and transformation strategies for a becoming housing quality
The resilience concept if referred to the built environment suggests ‘safety’ and recovery capacities that express adaptability and transformability characteristics. Recognising in the housing settlements many very significant aspects for inspecting the built systems adaptation and transformation needs, we present an extract of the research carried out on the housing topic, in agreement with the A.T.E.R. of Pescara and Abruzzo Confcooperatives. The work proposes indicators and criteria to allow the survey of the resilience capacities that can project the housing systems in a sustainable dimension, in which the aptitude to regeneration suggests the inhabitants know-how in the resources management, for a swell performance supply
Design and Characterization of Glyceryl Monooleate-Nanostructures Containing Doxorubicin Hydrochloride
Glyceryl monooleate (GMO) is one of the most popular amphiphilic lipids, which, in
the presence of dierent amounts of water and a proper amount of stabilizer, can promote the
development of well defined, thermodynamically stable nanostructures, called lyotropic liquid crystal
dispersions. The aim of this study is based on the design, characterization, and evaluation of the
cytotoxicity of lyotropic liquid crystal nanostructures containing a model anticancer drug such as
doxorubicin hydrochloride. The drug is eciently retained by the GMO nanosystems by a remote
loading approach. The nanostructures prepared with dierent non-ionic surfactants (poloxamers
and polysorbates) are characterized by dierent physico-chemical features as a function of several
parameters, i.e., serum stability, temperature, and dierent pH values, as well as the amount of
cryoprotectants used to obtain suitable freeze-dried systems. The nanostructures prepared with
poloxamer 407 used as a stabilizer show an increased toxicity of the entrapped drug on breast cancer
cell lines (MCF-7 and MDA-MB-231) due to their ability to sensitize multidrug-resistant (MDR) tumor
cells through the inhibition of specific drug eux transporters. Moreover, the interaction between
the nanostructures and the cells occurs after just a few hours, evidencing a huge cellular uptake of
the nanosystems
Oleuropein-Laded Ufasomes Improve the Nutraceutical Efficacy
Ufasomes are unsaturated fatty acid liposomes made up of oleic and linoleic acids, natural
components required in various biological processes. This kind of nanocarrier is characterized
by a simple and dynamic structure and is able to improve the bioavailability of unsaturated fatty
acids. The aim of this investigation was to evaluate ufasomes as natural compound delivery systems
to deliver oleuropein and improve its antioxidant activity. Oleuropein is a phenolic compound
mainly present in olives and olive oil, with several biological properties, such as the antioxidant
activity. However, to improve their biological activity, antioxidant compounds should be able to
cross cell membranes and uniformly incorporate in cells. Because of the great similarity between
their constituents and cell membranes, ufasomes could be advantageous carriers for oleuropein
delivery. The physico-chemical characteristics of ufasomes were investigated. A regular shape was
shown by transmission electron microscopy studies, while the mean sizes were dependent on the
ufasomes composition. In vitro studies highlighted that empty ufasomes did not lead to cell mortality
at the tested concentrations and a good carrier internalization in CaCo-2 cells, further studies in vitro
studies demonstrated that oleuropein-loaded ufasomes were able to enhance the antioxidant activity
of the free active substance making this carrier a suitable one for nutraceutical application
Identification of a Sorbicillinoid-Producing Aspergillus Strain with Antimicrobial Activity Against Staphylococcus aureus: a New Polyextremophilic Marine Fungus from Barents Sea
The exploration of poorly studied areas of Earth can highly increase the possibility to discover novel bioactive compounds. In this study, the cultivable fraction of fungi and bacteria from Barents Sea sediments has been studied to mine new bioactive molecules with antibacterial activity against a panel of human pathogens. We isolated diverse strains of psychrophilic and halophilic bacteria and fungi from a collection of nine samples from sea sediment. Following a full bioassay-guided approach, we isolated a new promising polyextremophilic marine fungus strain 8Na, identified as Aspergillusprotuberus MUT 3638, possessing the potential to produce antimicrobial agents. This fungus, isolated from cold seawater, was able to grow in a wide range of salinity, pH and temperatures. The growth conditions were optimised and scaled to fermentation, and its produced extract was subjected to chemical analysis. The active component was identified as bisvertinolone, a member of sorbicillonoid family that was found to display significant activity against Staphylococcus aureus with a minimum inhibitory concentration (MIC) of 30 μg/mL. © 2018, Springer Science+Business Media, LLC, part of Springer Nature
Pattern of care for re-irradiation in locally recurrent rectal cancer: a national survey on behalf of the AIRO gastrointestinal tumors study group
PurposeRadical resection (R0) represents the best curative treatment for local recurrence (LR) rectal cancer. Re-irradiation (re-RT) can increase the rate of R0 resection. Currently, there is a lack of guidelines on Re-RT for LR rectal cancer. The Italian Association of Radiation and clinical oncology for gastrointestinal tumors (AIRO-GI) study group released a national survey to investigate the current clinical practice of external beam radiation therapy in these patients.Material and methodsIn February 2021, the survey was designed and distributed to members of the GI working group. The questionnaire consisted of 40 questions regarding center characteristics, clinical indications, doses, and treatment techniques of re-RT for LR rectal cancer.ResultsA total of 37 questionnaires were collected. Re-RT was reported as an option for neoadjuvant treatment in resectable and unresectable disease by 55% and 75% of respondents, respectively. Long-course treatment with 30-40 Gy (1.8-2 Gy/die, 1.2 Gy bid) and hypofractionated regimen of 30-35 Gy in 5 fractions were used in most centers. A total dose of 90-100 Gy as EqD2 dose (& alpha;/& beta; = 5 Gy) was delivered by 46% of the respondents considering the previous treatment. Modern conformal techniques and daily image-guided radiation therapy protocols were used in 94% of centers.ConclusionOur survey showed that re-RT treatment is performed with advanced technology that allow a good management of LR rectal cancer. Significant variations were observed in terms of dose and fractionation, highlighting the need for a consensus on a common treatment strategy that could be validated in prospective studies
Guidelines for the use and interpretation of diagnostic methods in adult food allergy
Food allergy has an increasing prevalence in the general population and in Italy concerns 8 % of people with allergies. The spectrum of its clinical manifestations ranges from mild symptoms up to potentially fatal anaphylactic shock. A number of patients can be diagnosed easily by the use of first- and second-level procedures (history, skin tests and allergen specific IgE). Patients with complex presentation, such as multiple sensitizations and pollen-food syndromes, frequently require a third-level approach including molecular diagnostics, which enables the design of a component-resolved sensitization profile for each patient. The use of such techniques involves specialists' and experts' skills on the issue to appropriately meet the diagnostic and therapeutic needs of patients. Particularly, educational programs for allergists on the use and interpretation of molecular diagnostics are needed
