What to look for HIV and std testing in Singapore ?
HIV is a whistle companion called “retrovirus”. The virus cannot reproduce RNA (, genetic material named the ribonucleic acid) only by it, and synthesizing the protein, and, therefore, cannot increase. It infects cells that can increase oneself, and the infected cells make their own RNA and necessary proteins and multiply. Before mentioning hiv and std testing singapore, let’s first explain what is HIV (mainly cd4-positive lymphocytes) proliferate.
How to take and use emergency contraceptives?
First of all, think that the reason (physical, economical factor, etc.) of the rape case and maternal protection method as mentioned above is a premise, but if contraception is not possible, it leads to unsafe sexual intercourse, or contraception fails. Let’s consult an obstetrics and gynecology department for hiv and std testing singapore immediately. It is certain to contact in advance by phone etc.
In addition, emergency contraceptives have a higher contraceptive effect than with oral contraceptives, but since it is not 100%, please consult a doctor even if the contraceptive effect is not obtained or if you could not take emergency contraceptives within 72 hours.
How does HIV infect immune cells and multiply?
Next, we will introduce the process until HIV infects immune cells and proliferates.
Immune cells HIV adheres to the surface of immune cells. Then, RNA, reverse transcriptase, and integrases in HIV are sent into immune cells.
- DNA synthesis
RNA that enters immune cells uses reverse transcriptase to create HIV DNA. RNA is like a single string. There, another string corresponding to the string is made using the material in the immune cell, and it makes it to a double helix state. That is the image of DNA.
HIV DNA produced in immune cells enters the nucleus of immune cells. The nucleus has the DNA of the immune cells themselves, but HIV DNA is incorporated into the DNA (provirus). Integrase is a substance necessary for the incorporation of DNA.
DNA in HIV components (RNA, protein, enzymes, etc.) orders you to make your own proteins and RNA from the nucleus. Then, HIV RNA and proteins, reverse transcriptase, etc. are made in immune cells. RNA polymerases in immune cells are transcribed into mRNA, mRNA is translated, and HIV proteins and enzymes are produced.
- Hiv maturation and immune cell prolapse (release into the bloodstream)
HIV RNA, proteins, enzymes, etc. Are assembled to form a new mass of HIV. The mass becomes the structure of the mussel like the first, and the immune cell is popped out. When jumping out of immune cells, a proteolytic enzyme called protease allows HIV to mature and pop out only after cutting the protein.
