 Nero became Emperor of the Roman Empire after the death of his adoptive father, Emperor Cladius, in AD 54. Nero was the last ruler of what historians call the "Julio Claudian" dynasty, and he ruled until his suicide in June 68 AD. Nero is best known for his story of playing the violin while Rome burns in a wild fire, but in fact this story is questionable. Nero is one of the most notorious men in history. During his reign he killed his mother Agrippina the younger and his first wife Octavia, and allegedly killed his second wife, Poppaia Sabina. In addition, ancient writers claim that Nero was the one who started the great fire of Rome in 64 AD in order to rebuild the center City. Although ancient writers drew many accusations against Nero, the evidence indicates that he enjoyed some popular support, as he was so passionate about music and the arts that he performed a public musical in Rome in AD 65. Suetonius, a critic of the second century A.D., wrote: "Nero missed any...

 Cytokines, those unknown protagonists of the immune system that often act as the first responders to infection, are molecules that allow the body's cells to communicate with each other, and are essential to the function of the immune system. Nevertheless, many cytokines may have a negative effect and result in what is known as a "cytokine storm." Many different immune cells produce these small signaling molecules, such as neutrophils - some of the first cells to travel to the site of infection - and mast cells - responsible for allergic reactions - macrophages, B cells and T cells, according to a 2014 review published in the journal Frontiers of Immunology. Immune biologist at the University of Arizona in Tucson Joyce Wu said: “Cytokines are transmitted from cells and then bind to specific receptors in both immune and non-immune cells, and they may send signals to the cell to modify how it grows or behaves, as almost every organ of the body has cells with receptors.  Che...

 1- Cholesterol level: Cholesterol levels tell your doctor about the fats in your blood. Unhealthy levels are associated with hardening of the arteries, which can cause: heart disease, heart attacks and strokes.

 Our diet affects the health of our bodies, and since hair is part of the body, it is necessary to refer to the nutrients that fortify it in order to improve the health and appearance of hair. Let's learn about the top ten foods to maintain healthy hair: 1. Salmon to keep the shine: Salmon, sardines, and mackerel are rich sources of omega-3, which is a type of healthy fatty acid that the body is unable to manufacture, as it is necessary to resort to external sources rich in it, such as fish or nutritional supplements. Omega-3 helps prevent many diseases, and plays an important role in hair growth and maintaining its luster and density. 2. Greek yogurt for increased growth: Milk contains an abundant amount of protein, and protein is the cornerstone of cell formation. Pantothenic acid, known as vitamin B5 - which is an important component of milk - helps improve blood flow to the scalp, which in turn helps in hair growth, and its effect has been noted in treating hair loss and thinni...
