About Giovanna Miluccio

Graduated in Biology of differentiation and reproduction at the Federico II University of Naples. He deepened the various aspects of infertility and MAP thanks to studies and an internship. but he went on with an experimental thesis in biochemistry on antimicrobial peptides working on cells, bacteria and proteins. After graduation, she continued to study to keep up to date, but he has not yet decided which path to take. Passion for writing and science, push her to collaborate with Minerva since 2015.

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. Indeed, 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", [...]

Tintarella…of Sun!

2021-07-08T15:12:37+02:008 July 2021|Categories: Curiosity|Tags: , , |

Have you ever been told “how white you are, get some sun "or" you don't have melanin? You never get tanned!”. Well, if it has never happened to you you are very lucky. If, on the other hand, you always hear the same story every year, welcome to the pale face club. But why in the summer some people tan more than others? What is melanin and how does it work? When we expose ourselves to the sun and UV rays hit our skin, a protective mechanism triggered by melanocytes is activated, epidermal cells, which produce melanin. Melanocytes are formed dendritic cells [...]

Multiple sclerosis: a technology against the fatigue

2021-07-02T13:44:07+02:002 July 2021|Categories: Medicine and Research|Tags: , , , , |

Multiple sclerosis is a neurodegenerative disease that affects the central nervous system, also referred to as "autoimmune" due to the reaction of the immune system directed towards the body. The immune defenses attack certain parts of the central nervous system, recognizing them as foreign bodies and activating an inflammatory process that can damage or cause the loss of myelin, a substance that lines nerve fibers like a sheath, and the cells that produce it. This process can take place in various areas, affecting the optic nerves, the cerebellum and spinal cord and it is for this reason that the symptoms of the disease may be different a [...]

New molecules with bactericidal activity

2021-07-13T20:35:54+02:0021 November 2017|Categories: Chemistry and Physics, No Category|Tags: , , |

The frequent use of antibiotics has led to the development of bacterial strains resistant to these drugs, prompting researchers to isolate new antibacterial molecules to counter them or peptides (proteins). This new class of antibiotics is represented by antimicrobial peptides (AMPs, Anti Microbial Peptides) which are already used in numerous fields such as agriculture, the food industry and aquaculture, to which must be added the clinical field that in the last 25 years has intensified its research. AMPs belong to the innate immune system, able to exert an antimicrobial action against various pathogens that are harmful to human health and the quality of food. Those of origin [...]

Assisted fertilization: the success of "sick" embryos

2021-07-13T20:48:17+02:0018 February 2016|Categories: Medicine and Research|Tags: , , |

The desire to have children leads many couples with fertility problems to resort to artificial techniques such as assisted reproduction. Although in Italy this technique is still the subject of strong discussion, research continues to make progress to ensure the success of embryo implantation. Before implantation in the maternal uterus, the embryos are analyzed and those that can be used are selected, in order to distinguish the healthy from the sick. However, a recent discovery has shown that not all diseased embryos need to be discarded, some can be used by increasing the chances of successful artificial insemination. Assisted reproduction is the process it mediates [...]

The effects of music on the brain

2021-07-13T21:24:49+02:0016 February 2016|Categories: Curiosity|Tags: , , |

The world is full of great musicians suffering from pathologies that have not stopped them from becoming "i geni" undisputed in the history of music. Just think of Schumann and his "streak of madness" later classified as "schizophrenia", Beethoven and his early deafness, Mozart and the "Tourette Syndrome" which he was probably suffering from which causes tics, high-pitched sounds and loss of speech control, Petrucciani died in 1999 of "osteogenesis imperfecta" or "crystal bone syndrome" and Ezio Bosso suffering from "amyotrophic lateral sclerosis" or ALS, a neurodegenerative disease affecting motor neurons. Despite the serious [...]
