To avoid pregnancy and STDs, always remember to use a condom every time you have sex — including oral, vaginal, or anal sex. Whenever oral sex is being performed on a girl, a dental dam should be used. A guy receiving oral sex should wear a latex condom — or, if he or his partner is allergic to latex, a polyurethane condom.

New advice for dialysis patients Scott 45 Views • 2 years ago

Dialysis patients need to choose their heart medicine carefully, as Canadian researchers say that some beta blockers are easily removed from the blood during treatment. Also, people who eat a Mediterranean diet may decrease their risk of developing kidney problems. Eboni Williams reports on the day's top health news.

Early Warning Signs of Skin Cancer (Melanoma)
Early Warning Signs of Skin Cancer (Melanoma) samer kareem 1,814 Views • 2 years ago

Skin cancer is the most common type of cancer. There are three major types of skin cancer — Basal Cell Carcinoma, Squamous Cell Carcinoma and melanoma. Out of these, Melanoma is the deadliest form of skin cancer. Melanoma appears on the skin as a new spot or growth or a change in an already existing mole. It is often fast growing and can spread to other parts of your body, including your bones, liver, and lungs to form a new cancer.

What Is Hemodialysis and How Does It Work?
What Is Hemodialysis and How Does It Work? Scott 65 Views • 2 years ago

What is hemodialysis and how does it work? Who needs it? How do you prepare for it? In the United States, over 30 million Americans have kidney disease, and sometimes, kidney disease progresses to kidney failure or end-stage renal disease. When this happens, you cannot survive unless you have a kidney transplant or some form of dialysis. So today we're going to talk about hemodialysis.

Your kidneys are the two kidney bean-shaped organs that are located in your lower back, or in your flanks. And the kidneys are responsible for filtering out or cleaning your blood. They get rid of excess waste, excess toxins, and excess fluids. If your kidneys stop functioning, then you develop renal failure or end-stage renal disease.

What is Hemodialysis?
Hemodialysis, or blood dialysis, is the filtering of your blood outside of your body. So, if your kidneys stop working properly, the hemodialysis acts as a substitute kidney. Now it's important to note that hemodialysis does not actually correct your own kidney function. It does not fix or treat your kidneys.

What is The Dialyzer?
The dialyzer is actually the filter. It's the main powerhouse of the hemodialysis system, and it is what actually acts as the substitute kidney. In the dialyzer, you have these hollow fibers that run through it, and these fibers are bathed in something called dialysates, or dialysis fluid.

How Often Are Patients Treated With Hemodialysis?
Most patients who are on hemodialysis are on it between three and six hours, about three days a week, especially if they go to a center.

How Does Hemodialysis Work?
So when you are on dialysis, how does your blood get from your body to the hemodialysis machine and then back to your body? Well, it does so through tubes, and those tubes are connected to your access, and we'll talk about access in just a moment. But as far as the tubing, the tubing is connected to your body.

Types Of Hemodialysis Access
Arteriovenous Fistula or AV Fistula
The AV fistula is the gold standard as far as hemodialysis access is concerned because it gives you the most efficient hemodialysis and it is the least likely to be infected.

Arteriovenous Graft or AV Graft
The AV graft is very similar to the AV fistula in that you still have a surgically connected artery and a vein, usually in the arm, but in the case where if you have veins that are rather thin or arteries that are thin and maybe too weak in order to really give you a properly functioning, substantial AV fistula, then the vascular surgeon may opt to add an artificial material in order to make that shunt a little stronger, or little more durable. And so, an AV graft is another option for dialysis access.

Catheter
If you're in a situation where you need temporary dialysis, or if you have acute kidney injury, then you may have a temporary Vascath placed, and it's usually placed in a vein of the neck, the internal jugular vein, or it can be placed in the groin, or in the femoral vein.

Who Needs Hemodialysis Treatment?
How do you know if you need hemodialysis, and when is it time to prepare? Well, if you follow up with your kidney doctor (nephrologist) regularly, he or she will be watching your labs. They'll be able to see those signs of your kidneys not functioning properly.

Childbirth (also called labour, birth, partus or parturition) is the culmination of a human pregnancy or gestation period with birth of one or more newborn infants from a woman’s uterus. The process of normal human childbirth is categorized in three stages of labour: the shortening and dilation of the cervix, descent and birth of the infant, and birth of the placenta. In some cases, childbirth is achieved through caesarean section, the removal of the neonate through a surgical incision in the abdomen, rather than through vaginal birth

HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,430 Views • 2 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

What is a brain aneurysm? A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result.
