COVID-19 pandemic: usefulness of telemedicine in management of arrhythmias in elderly people

In March 2020, the WHO defined the diffusion of novel coronavirus, Severe Acute Respiratory Syndrome-Coronavirus- 2 (SARS-CoV-2) as pandemic.[13] As a consequence, the Italian Government among others has enforced quarantine on the population to contain the diffusion of the infection

Early-stage formation of (hydr)oxo bridges in transition-metal catalysts for photosynthetic processes

Ab initio simulations have been used to assess reaction pathways for the formation of M–(hydr)oxo–M (M = Co, Mn, Ni) bridges from M(ii) aqueous solutions, as early-stage building blocks of transition-metal catalysts for oxygen evolution

Influence of Dietary Supplementation with Prebiotic, Oregano Extract, and Vitamin E on Fatty Acid Profile and Oxidative Status of Rabbit Meat

The effect of dietary supplementation with vitamin E, oregano, and prebiotic on fatty acids and oxidative profiles of rabbit meat (loin and hind leg) was evaluated. New Zealand white rabbits weaned at 30 days of age were fed with one of six diets until 80 days of age: standard diet includingω3 polyunsaturated fatty and conjugated linolenic acids sources (S) and five diets adding vitamin E (150 ppm, E), oregano water extract (2 g/kg feed diet, O), prebiotic (THEPAX® 1.5 g/kg feed diet, T), vitamin E plus prebiotic (TE), and oregano water extract plus prebiotic (TO), respectively. The lipid oxidative status (TBARS) showed lower values with respect to S, mainly when vitamin E was administered. In particular, all the experimental diets decreased TBARS values with respect to the control group in the loin, but no effect was found in the hind leg. In all feed samples, the amounts of fatty acid classes increased in the following order: polyunsaturated fatty acids > monounsaturated fatty acid > saturated fatty acid. The dietary supplementations did not affect the fatty acid composition of meat. The experimented diets compared to the control were not able to provide a selective increase of bioactive fatty acid in meat samples; however, the six nutritional strategies led to highly nutritional rabbit meat with an interesting value of theω6/ω3 ratio

Assessing and mapping biomass potential productivity from poplar-dominated riparian forests: A case study

River systems are subjected to continuous physical changes as a result of their sediment transport. River dynamics is mainly determined by the seasonal variation of weather conditions and, together with the nature of the catchment and land management, affects flow patterns on a local scale. Riparian vegetation is well adapted to this periodical disturbance. It naturally regenerates on the new mineral soil created by the redistribution of river sediments during floods, playing an important role in the maintenance of streams and riverbanks stability. The high level of resilience and productivity of riparian tree species like Populus, contributes to the rapid biomass accumulation of riparian vegetation making these ecosystems of potential interest for biomass production for energy. This paper presents an operational methodology for investigating the biomass potential from riparian forests by coupling airborne laser scanning data and field survey. A case study on assessing and mapping biomass dynamics over a seventeen year period along a tract on the Paglia river, in Central Italy, is presented and discussed. The results highlight that the surface of the poplardominated riparian vegetation has significantly changed over the 1989e2006 period. More than 70 ha of new poplar forest were naturally regenerated during the analyzed period. The total amount of aboveground woody biomass of the riparian forest at the second inventory occasion has been estimated in 88 Mg ha!1, evidencing a large amount of technically available resources for bioenergy production (around 80% of the standing woody biomass). The innovative strategy here proposed to assess and map at a very high spatial resolution the abovegroundwoody biomass of riparian forest meets the monitoring requirements to support energy production based on modern, non-conventional biomass harvest planning options

Successful treatment of Neuroblastoma in an adolescent with intra-arterial embolization before surgery

Abstract Introduction Neuroblastoma in the adolescent is characterized by indolent growth and poor outcome. Surgical resection of the tumor is an essential part of the multimodality treatment. Surgical complications depend on the presence of Image Defined Risk Factors (IDRFs). Methods We present an adolescent with pelvic neuroblastoma and epidural compression. To facilitate tumor resection, the patient underwent preoperative selective embolization. Results After selective embolization a subsequent complete resection etraspinal localisation was performed without complication with complete remission after 2 years. Conclusions Preoperative embolization is a safe and feasible technique that can help pediatric surgical oncologist to reduce complications IDRFs-related

Metabolism of Stem and Progenitor Cells: Proper Methods to Answer Specific Questions

Stem cells can stay quiescent for a long period of time or proliferate and differentiate into multiple lineages. The activity of stage-specific metabolic programs allows stem cells to best adapt their functions in different microenvironments. Specific cellular phenotypes can be, therefore, defined by precise metabolic signatures. Notably, not only cellular metabolism describes a defined cellular phenotype, but experimental evidence now clearly indicate that also rewiring cells towards a particular cellular metabolism can drive their cellular phenotype and function accordingly. Cellular metabolism can be studied by both targeted and untargeted approaches. Targeted analyses focus on a subset of identified metabolites and on their metabolic fluxes. In addition, the overall assessment of the oxygen consumption rate (OCR) gives a measure of the overall cellular oxidative metabolism and mitochondrial function. Untargeted approach provides a large-scale identification and quantification of the whole metabolome with the aim to describe a metabolic fingerprinting. In this review article, we overview the methodologies currently available for the study of invitro stem cell metabolism, including metabolic fluxes, fingerprint analyses, and single-cell metabolomics. Moreover, we summarize available approaches for the study of in vivo stem cell metabolism. For all of the described methods, we highlight their specificities and limitations. In addition, we discuss practical concerns about the most threatening steps, including metabolic quenching, sample preparation and extraction. A better knowledge of the precise metabolic signature defining specific cell population is instrumental to the design of novel therapeutic strategies able to drive undifferentiated stem cells towards a selective and valuable cellular phenotype
