Allergies: a mystery to our immune system

2024-03-20T11:54:25+01:0020 March 2024|Categories: Medicine and Research, No Category|Tags: , , |

Hai mai sentito parlare delle allergie? Probabilmente ti sono già molto familiari se hai a che fare con starnuti e occhi arrossati durante la stagione dei pollini, o se hai imparato a gestire le reazioni ai cibi che ami ma che il tuo corpo respinge. Queste reazioni, un po’ esagerate, sono dei piccoli errori che il nostro corpo fa quando cerca di proteggerci dagli invasori cattivi ma si confonde e attacca cose che non dovrebbe. Immagina che il tuo corpo sia un castello e il sistema immunitario sia il tuo esercito che lo protegge dagli invasori. Now, ogni tanto, [...]

Mitochondrial replacement therapy: what it's about, and why it's nothing new.

2024-03-01T12:00:24+01:001 March 2024|Categories: Medicine and Research|Tags: , , , , , , , , , , , |

Mitochondrial replacement therapy (mitochondrial replacement therapy, or MRT) is an innovative reproductive technology aimed at preventing the transmission of mitochondrial diseases from mother to child. Mitochondria are organelles contained within our cells that produce energy. They contain 37 stamina cells, less than 0,1 % of the genetic material of our species, the vast majority of which is found within the nucleus of our cells. How MRT works When mutations occur in mitochondrial DNA, these can lead to the inheritance of serious neurodegenerative diseases, currently without treatment, which mainly affect tissues with high energy expenditure, like heart, [...]

World Day of’ Alzheimer

2023-09-21T10:22:12+02:0021 September 2023|Categories: Medicine and Research|Tags: , , , |

Alzheimer's Disease: Una Luce all'Orizzonte grazie alla Ricerca La malattia di Alzheimer è da tempo al centro dell'attenzione della comunità scientifica. Descritta per la prima volta più di un secolo fa, continua a rappresentare una delle sfide più complesse per la medicina moderna. Immaginate un meccanismo d'orologeria complicatissimo e capirete quanto sia difficile decifrare il puzzle dell'Alzheimer. Ogni ticchettio di quell'orologio rappresenta, Unfortunately, una persona che riceve questa diagnosi - si calcola infatti che una nuova persona venga colpita dalla malattia ogni tre secondi nel mondo. Con una popolazione mondiale che vive sempre più a lungo, le [...]

World Brain Day 2023: “Brain Health and Disability: Leave No One Behind”

2023-07-21T23:31:27+02:0021 July 2023|Categories: Medicine and Research|Tags: , , , , |

World Brain Day, il World Brain Day, che si celebra oggi 22 July, è promossa annualmente dalla World Federation of Neurology (WFN), la Federazione mondiale di Neurologia, con lo scopo di sensibilizzare la popolazione mondiale sulle problematiche relative alla salute mentale e aumentare la consapevolezza globale circa le patologie neurologiche e neurodegenerative. La visione del WFN è di portare i concetti di necessità di cure e servizi, diritto alla salute del cervello per tutta la durata della vita e riduzione dello stigma intorno alla disabilità. Quando si tratta di salute del cervello, non possiamo lasciare indietro nessuno. [...]

The Exosomes: message bombs between cells

2023-06-27T10:32:30+02:0027 June 2023|Categories: Medicine and Research|

Exosomes are a recently discovered mode of cellular communication. Initially mistaken for scraps, could prove to be a promising tool for diagnosis and therapy. We are used to thinking of our body as a single machine, forgetting that it is instead made up of many parts. Each organ is made up of different tissues and many cells. However, the number of bacteria in our body exceeds that of our cells. And this makes us doubt that we might not be made of dreams but of bacteria. All these parts must communicate with each other to work. Just like in a car. [...]

The use of plants by prehistoric men: help from sediment palaeogenetics

2023-06-16T11:17:18+02:0016 June 2023|Categories: Curiosity, Medicine and Research, Nature, Technology|Tags: , , |

Le nostre attuali conoscenze sull'utilizzo delle piante da parte della nostra specie durante il Paleolitico (2,5 mln - 12000 Years ago) are documented thanks to fragments of plants, phytoliths and microfossils, as well as biomarkers from food preparation tools and dental calculus, but are quite limited due to the poor preservation of identifiable plant remains and the lack of adequate methods for their detection and identification. However, uno studio internazionale abbastanza recente ci mostra come, grazie all'analisi del DNA conservato nei sedimenti delle grotte (ambienti unici in cui l'effetto completo degli elementi sui materiali [...]

Resistance to antibiotics: gallium for cystic fibrosis

2023-04-16T16:13:33+02:0016 April 2023|Categories: Medicine and Research|Tags: , , , |

Negli ultimi anni abbiamo assistito a un notevole aumento di batteri resistenti agli antibiotici che ha reso inefficaci molte terapie e, Consequently, the treatment of various pathologies caused by bacterial infections. According to the World Health Organization (OMS) every year 700 mila persone nel mondo muoiono a causa di un’infezione dovuta a batteri resistenti agli antibiotici e di queste circa 10 thousand in Italy. Uno dei motivi principali che ha scatenato questa resistenza è l’abuso di antibiotici, in fact it is thought that there could be a further increase in antibiotic-resistant bacteria due to the COVID-19 pandemic, per il largo utilizzo di [...]

Mice born to two dads: how much is true?

2023-03-18T18:29:11+01:0018 March 2023|Categories: Medicine and Research|Tags: , , |

According to the latest news, everything seems possible for genetic engineering, also procreation by beings of the same sex. The news of the birth of offspring from two fathers was recently reported in several newspapers. But how much truth is there in this news? It is really possible to give birth to a life from the natural mating of two male beings? As told by the biologist Katsuhiko Hayashi on the occasion of the conference dedicated to genome editing in London, his team in the laboratory at Kyushu University in Japan generated new lives from two same-sex parents using a model of [...]

Provora: the new supergroup of eukaryotes

2022-12-21T13:29:32+01:0021 December 2022|Categories: Medicine and Research|Tags: , , , |

“Provora” is the new supergroup of eukaryotic microorganisms (organisms with a well-differentiated nucleus, made up of one or more cells) discovered in some geographically distant marine habitats, precisely near the coral reefs of Curacao in the Caribbean sea, in the Black and Red Sea areas, in the waters of the Arctic Ocean and north-east of the Pacific Ocean. Tikhonenkov, Keeling and other authors of this scientific investigation, taking some water samples, they found these very small strains equipped with two flagella, o code (i.e. long filamentous structures important for movement), located in separate pockets, that swim quickly and prey [...]
