The collection of glass

2022-05-25T11:34:53+02:0025 May 2022|Categories: Curiosity|Tags: , , , , |

Glass is an amorphous material, that is, a liquid that undergoes solidification without however acquiring the ordered structure of the crystals, instead maintaining a disordered and rigid structure. Its discovery dates back to the Phoenicians who at the time understood that by combining sodium carbonate and silica sand, glass was obtained. In fact, in common parlance with glass we mean that material formed by calcium, soda and silicon which sees its application in different fields, such as the making of containers, part of the furniture (windows) or manufacture of decorative elements (objects and chandeliers). I diversi utilizzi del vetro sono dovuti [...]

The impact of food on the environment: towards sustainable nutrition

2022-05-12T11:57:36+02:007 May 2022|Categories: Curiosity|Tags: , , , |

Environmental changes are hardly a mystery. It is increasingly evident how human activities are damaging everything around them.; from the soil to the air, to the water and every water channel. When it comes to pollution, factories are mainly blamed., waste or transport, but few think about food. Now you may wonder: "What does food have to do with the environment?” La risposta è molto semplice: “Quello che mangiamo è importante non solo per la nostra salute ma anche per il pianeta”. The World Food and Agriculture Organization (FAO) ha dichiarato che l’attuale produzione alimentare sta [...]

The genetic profile in male infertility

2022-04-25T10:54:34+02:0024 April 2022|Categories: Medicine and Research|Tags: , , |

Over the last 20 years we have witnessed a decrease in the birth rate also due to a decrease in fertility, as demography shows. In fact, an increase in the percentage of aging is estimated by 2050 worldwide. According to the data, one in five couples cannot procreate naturally. The reasons could be many, but, among these, it affects a lot than in the last 30 years, the average age of conception in both sexes has increased by almost 10 years and lifestyles have changed to the point of damaging fertility. Often, mistakenly, they tend to [...]

Endometriosis: a phantom disease

2022-03-26T15:34:54+01:0026 March 2022|Categories: Medicine and Research|Tags: , , , |

"To prevent is better than to cure" as the old saying goes, but to prevent it is necessary to know and this is one of the problems of endometriosis: we don't talk enough about it, yet it affects 1 woman out of 10 and represents the 30% of the causes of female infertility. That's high enough for a phantom disease, a pathology that exists but is not seen or at least not immediately because the symptoms and alarm bells that reach our body are often underestimated. All this because of poor awereness, and because in 2020 unfortunately some topics are still taboo. Endometriosis, as the [...]

Unexpected mutations in gene editing

2022-02-08T18:59:56+01:008 February 2022|Categories: Medicine and Research|Tags: , , |

Many of you will have already heard of CRISPR-Cas9, the so-called molecular scissors that serve to modify the DNA of many organisms. This technique has represented a revolution in the field of genetic engineering in recent years due to its ability to "cut and sew" a specific DNA sequence to make corrections in target genes. So much so that it has opened new avenues and new possibilities for gene therapy, that is, the possibility of treating or preventing diseases by intervening directly on the patient's genome. But how advanced are these techniques today? And what are the risks? The use of CRISPR which created more [...]

The epigenetic supersimilarity of monozygotic twins

2021-07-14T21:41:06+02:0014 July 2021|Categories: Medicine and Research|Tags: , , |

Monozygotic twins are identical individuals born from the fertilization of a single egg cell from a sperm that have the same genetic makeup. The common elements between two identical twins do not only concern genetics but also involve epigenetics, that is the set of molecular mechanisms that regulate the expression of genes without modifying the DNA. A type of epigenetic modification studied in twins is methylation which consists in the addition of a methyl group (-CH3) to a nitrogenous base. Through the study of metastable epialleles (ME), epigenetic variants set up in the early embryo and maintained during subsequent cell differentiation, it was possible to observe that [...]

Lactose and gluten intolerance: what you need to know!

2021-07-14T21:01:19+02:0014 July 2021|Categories: Food and Health|Tags: , , |

We have previously explained the difference between allergy and intolerance, now let's go into the details of the most widespread intolerances in the population and their causes. What is lactose intolerance? Because the body cannot metabolize it? Lactose is a disaccharide, that is, a compound sugar present in dairy products and all its derivatives, formed by two simpler sugars: glucose and galactose. Normally the body metabolizes it through lactase, an enzyme produced by some bacteria such as lactobacilli and bifidobacteria. Lactase breaks the bond between glucose and galactose and allows their digestion. When the enzyme is reduced or [...]

Where satiety is born?

2021-07-14T12:59:22+02:0013 July 2021|Categories: Food and Health|Tags: , , , |

The sense of satiety induces man not to eat continuously and puts a brake on his need, often excessive, of food. Hunger and satiety affect everyone's eating behavior, but what exactly do they depend on? Satiety is a signal triggered by the brain when it receives too much sugar. In fact, after a meal, when glucose levels momentarily rise, the signal reaches our brain, more precisely to astrocytes, the cells needed to support neurons. The astrocytes, at this point, they change shape and retract by activating some specific neurons of the hypothalamus, a structure of the central nervous system located in the [...]

Food intolerances and allergies

2021-07-14T17:18:25+02:009 July 2021|Categories: Food and Health|Tags: , , |

Very often intolerance to allergy is associated with making a mistake because the underlying mechanisms are very different. Allergy is caused by the introduction into the body of a foreign body that is not recognized by the immune system, which reacts by attacking it and thus triggering serious complications up to anaphylactic shock. Food intolerances are food-related disorders that are not caused by the immune system, as is the case with allergies. They are very common in the population and a good part suffer from them, but once we have identified the foods we are intolerant to, we can change our eating habits to get better, thanks also to [...]

The genetics of roses

2021-07-09T17:40:23+02:008 July 2021|Categories: Nature|Tags: , , |

Roses are the most widely grown ornamental plants in the world, also important from an economic point of view in the cosmetic industry. The ornamental features, the therapeutic and cosmetic value have contributed to its domestication but the evolution of the Rosa genus is very complex. The genus Rosa, belonging to the Rosaceae family, contains approximately 200 species, many of which are polyploid, that is, they have multiple chromosomal sets, but only from 8 all 20 species are involved in the cultivation of hybrid roses (Rosa hybrida), among these there is a very important Chinese species known as "Rosa chinensis". These crossings gave birth to the "Rosa tea", [...]
