RE.99mTc-HMPAO-leucocyte scintigraphy and [18F]FDG-PET/CT in infection
Full text linkSir,
I read with interest the article “99mTc-HMPAO-white blood cell (WBC) scintigraphy and [18F]FDG-PET/CT for diagnosis and therapy monitoring in eleven patients with skull base osteomyelitis” by Vion Pierre-Adrien and co-workers.1 The topic is interesting because there are very few reports on the use of nuclear medicine techniques in the investigation of skull base infections. The study is well designed. This is one of very few studies that evaluate patients' pre- and post-therapy with 2 different modalities.2 However, some considerations should be made in order to correctly interpret these data
How has the consistency of the Common catalogue of varieties of vegetable species changed in the last ten years?
No full textIn the EU Countries, only the propagation organs of varieties that are distinct, stable, and uniform and with an appropriate value for cultivation or use may be marketed. For this reason, since 1972 the European community has implemented the “Common catalogue of varieties of vegetable species”, which incorporates the relevant national registers and includes 58 species. In this review, we consider the complete edition of “Common catalogue of varieties of vegetable species” of 2018 (37th edition) and 2008 (27th edition), in order to assess the changes that have occurred to several Countries, to species (specific and intraspecific diversity) and to propagation/seed type (hybrid varieties, open-pollinated varieties, agamic propagation varieties and “conservation varieties”). The most important Country is always The Netherlands, which in the 2018 Common catalogue holds 8350 varieties (40.4 % of total). The species with the greater number of varieties are tomato (3675 varieties), pepper (2216) and lettuce (2114). In the last ten years, the number of hybrid varieties has increased from 9507 to 11,871, while the common varieties have increased from 7683 to 7,706. In this review, we discuss such data in relation to the innovation that the horticultural sector has registered in recent years
The reconstructed natural history of type 1 diabetes mellitus
No full textThe causes of type 1 diabetes mellitus (T1DM) are unclear; however, a general consensus exists that T1DM is a T cell-mediated autoimmune disease characterized by the selective destruction of insulin-secreting β-cells. Now, two imaging mass cytometry studies of human pancreatic tissue illuminate new biology in the pathogenesis of T1DM
Nuclear Medicine Imaging of Infections. Techniques, Acquisition Protocols and Interpretation Criteria
No full textIn the past decades, nuclear medicine has developed enormously for imaging infections and in many cases has become an indispensable diagnostic tool for clinicians. Nuclear medicine techniques can facilitate the investigation, in vivo, of different pathogenetic events occurring in the natural history of the diseases. This chapter talks about techniques for imaging inflammation/infection, cardiovascular infections, preimaging considerations and patient preparation, image acquisition protocols for white blood cells (WBCs) and antigranulocyte monoclonal antibodies (anti-G mAbs), and interpretation criteria for WBCs, anti-G mAbs, and fluorodeoxyglucose (FDG). It provides lists of commercially available radiopharmaceuticals for imaging inflammation/infection, and experimental radiopharmaceuticals for imaging inflammation/infection, fungi and bacteria. Nuclear medicine techniques in most cases are complementary to radiological techniques and efforts are ongoing in the scientific community to define common diagnostic flow charts for effective diagnosis of infections, reducing unnecessary costs and optimizing available resources
Optimizing product quality in soilless culture systems (SCS)
No full textIn the soilless culture system (SCS), several quality parameters of the produce may be modified, often in a favourable sense with respect to the traditional cultivation on soil, due to the better control of the environmental and technical factors.
In this chapter, the main factors through which it is possible to influence and improve the quality profile of soilless horticultural produce are considered. These include the composition, temperature and management of the nutrient solution, the electrical conductivity, as well as the biofortification and harvested methods.
The qualitative profile products from plants, grown in SCS is substantially comparable to that of the corresponding products from soil, or even better. The differences, if ascertained, seem mostly in favour of SCS, in particular for the parameters inherent the nutritional, organoleptic, and health and hygiene characteristics
I prodotti agroalimentari tradizionali (PAT), espressione del territorio e del patrimonio culturale italiano.
Full text linkThe term "Traditional agri-food products (PAT)" refers to those products whose processing, preservation and maturing methods are practiced in a given territory in a homogeneous manner and according to traditional rules and consolidated over time for a period of no less than twentyfive years. The national list of PATs is published and updated annually by the Italian Ministry of Agricultural, Food and Forestry Policy. The first list of 2000 contained 2,188 PAT; in 2018 there are included in the same list 5,056 PAT. Among the 20 Italian regions, in first place we find Campania (with 515 PAT), followed by Tuscany (461) and Lazio (409). The Campania is also the region with the highest percentage of plant products (223), followed by Tuscany (192), Veneto (118), Liguria and Puglia (both with 101). In the national list of PAT, it is possible to find numerous plant genetic resources and in particular local varieties, consumed as such or as an ingredient in gastronomic products. European consumers largely say (77%) that respect for local tradition and know-how is an important factor in their decision to buy European food products. In general, consumers associate local products with freshness and genuineness, link with the landscape, adoption of eco-sustainable production methods, traceability, non-approved food and sociality linked to local purchasing. For all these reasons the PAT represent an important and original expression of the vast Italian cultural heritage and can become a useful lever for the promotion of Italian territories and agriculture
