  1. Vitamin B12 (or vitamin B-12) is also called cobalamin. It has a key role in the normal functioning of the brain and nervous system, and in the formation of blood. It is one of the eight B vitamins. B 12 is normally involved in the metabolism of every cell of the human body, especially DNA synthesis and regulation, but also fatty acid and amino ...

    There are many genomic structures in viruses. As a group they are more diverse than plants, animals, archaea, or bacteria. There are millions of different types of viruses, but only about 7,000 of them have been described in detail.49 A virus has either RNA or DNA genes and so is called an RNA virus or a DNA virus. The vast majority of viruses have...

    Viral populations do not grow through cell division, because they do not have cells. Instead, they use the machinery and metabolism of a host cell to produce many copies of themselves, and they assemble(put together) in the cell. The life cycle of viruses differs greatly between species but there are six basic stages in the life cycle of viruses:75...

    Innate immune system

    The body's first line of defence against viruses is the innate immune system. This has cells and other mechanisms which defend the host from any infection. The cells of the innate system recognise, and respond to, pathogens in a general way. RNA interference is an important innate defence against viruses. Many viruses have a replication strategy that involves double-stranded RNA (dsRNA). When such a virus infects a cell, it releases its RNA molecule. A protein complex called dicersticks to it...

    Adaptive immune system

    Vertebrates have a second, more specific, immune system. It is called the adaptive immune system. When it meets a virus, it produces specific antibodiesthat bind to the virus and render it non-infectious. Two types of antibodies are important. The first, called IgM, is highly effective at neutralizing viruses but is produced by the cells of the immune system only for a few weeks. The second, called IgG, is produced indefinitely. The presence of IgM in the blood of the host is used to test for...

    Evading the immune system

    Not all virus infections produce a protective immune response. These persistent viruses evade immune control by sequestration (hiding away); cytokine resistance; evading natural killer cell activity; escape from apoptosis (cell death), and antigenic shift (changing surface proteins). HIV evades the immune system by constantly changing the amino acid sequence of the proteins on the surface of the virion. Other viruses move along nervesto places the immune system cannot reach.

    Viruses do not belong to any of the six kingdoms. They do not meet all the requirements for being classified as a living organism because they are not active until the point of infection. However, that is just a verbal point. Obviously, their structure and mode of operation means they have evolved from other living things, and the loss of normal st...

    A recent project discovered nearly 1500 new RNA viruses by sampling over 200 invertebrate species. "The research team... extracted their RNA and, using next-generation sequencing, deciphered the sequence of a staggering six trillion letters present in the invertebrate RNA libraries". The research showed that viruses changed bits and pieces of their...

    A group of large viruses infect amoebae. The largest is Pithovirus. Others in order of size are Pandoravirus, then Megavirus, then Mimivirus. They are bigger than some bacteria, and visible under a light microscope.

    Viruses are everywhere in the sea. They may outnumber all other forms of marine life by at least an order of magnitude. Through selective infection, viruses influence nutrientcycling and evolution in the ocean.

    Viruses are used widely in cell biology. Geneticists often use viruses as vectors to introduce genes into cells that they are studying. This is useful for making the cell produce a foreign substance, or to study the effect of introducing a new gene into the genome. Eastern European scientists have used phage therapy as an alternative to antibiotics...

  5. A healthy diet or balanced diet. is a diet (what you eat) that contains the right amounts of all the food groups. It includes fruit, vegetables, grains, dairy products, and protein. It does not include too much or too little of any kind of food. [1] Eating wrong amounts of a food group, whether it be too much or too little, is called an ...

  6. Semaglutide, sold under the brand names Ozempic, Wegovy and Rybelsus, is a drug used to treat type 2 diabetes and reduce obesity. It was developed by Novo Nordisk in 2012. [1] It was approved for use in America in 2017. [2]
