Viagra for Women

Viagra works by blocking an enzyme that acts as an inhibitor of blood flow. In men, this can cause penile tissue to swell. When a man takes Viagra, there is an increase in blood flow to the genital areas, which thus helps to treat erectile dysfunction or impotence in men.

The same enzyme inhibitor affecting male sexual dysfunction influences pelvic blood flow in women. The Viagra research team attempted to find a link between arousal in women and pelvic blood flow in the early stages of trials. However, this attempt failed, and some researchers even suggested that genital arousal in women does not necessarily produce sexual desire in women as it typically does in men. Women may define sexual arousal based on mental and emotional, as well as biological factors.

According to some of the researchers working on the Viagra team, Viagra for women or a Viagra alternative may help women facing sexual dysfunction due to side effects of other medication. In cases where sexual desire is inhibited due to emotional or psychological factors, a female Viagra solution may not be applicable.

Laparoscopic surgery

Laparoscopic surgery, also called minimally invasive surgery (MIS), bandaid surgery, keyhole surgery is a modern surgical technique in which operations in the abdomen are performed through small incisions (usually 0.5-1.5cm) as compared to larger incisions needed in traditional surgical procedures.

Practicioners of "open" surgery sometimes use the misleading defensive term "microscopic" surgery, which implies a small incision. However, open surgery typically requires an incision large enough for the surgeon's hands to enter the patient, while the term microscopic refers to various magnifying devices used during open surgery. Keyhole surgery uses images displayed on TV monitors for magnification of the surgical elements.

Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy.

There are a number of advantages to the patient with laparoscopic surgery versus an open procedure. These include reduced pain due to smaller incisions and haemorrhaging, and shorter recovery time.

The key element in laparoscopic surgery is the use of a laparoscope. There are two types: (1) a telescopic rod lens system, that is usually connected to a video camera (single chip or three chip), or (2) a digital laparoscope where the charge-coupled device is placed at the end of the laparoscope, eliminating the rod lens system.[1] Also attached is a fiber optic cable system connected to a 'cold' light source (halogen or xenon), to illuminate the operative field, inserted through a 5 mm or 10 mm cannula or trocar to view the operative field. The abdomen is usually insufflated, or essentially blown up like a balloon, with carbon dioxide gas. This elevates the abdominal wall above the internal organs like a dome to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.

Neuroscience

Neuroscience is the scientific study of the nervous system. Such studies span the structure, function, evolutionary history, development, genetics, biochemistry, physiology, pharmacology, informatics, computational neuroscience and pathology of the nervous system.

The International Brain Research Organization was founded in 1960,[1] the European Brain and Behaviour Society in 1968,[2] and the Society for Neuroscience in 1969,[3] but the study of the brain dates at least to ancient Egypt. Traditionally, neuroscience has been seen as a branch of the biological sciences. Recently, however, there has been a surge of interest from many allied disciplines, including cognitive and neuro-psychology, computer science, statistics, physics, philosophy, and medicine. The scope of neuroscience has now broadened to include any systematic, scientific, experimental or theoretical investigation of the central and peripheral nervous system of biological organisms. The empirical methodologies employed by neuroscientists have been enormously expanded, from biochemical and genetic analyses of the dynamics of individual nerve cells and their molecular constituents to imaging of perceptual and motor tasks in the brain. Recent theoretical advances in neuroscience have been aided by the use of computational modeling.

HIV/AIDS TREATMENT AND CARE

June 2008 — Health experts estimate that approximately 25% of Americans infected with HIV do not know their status — a figure that has profound public health implications. In fact, evidence suggests that most new infections stem from people who are unaware of their HIV status, according to the U.S. Centers for Disease Control and Prevention (CDC).All sexually active people, particularly those who have had multiple sex partners — gay or straight— should get tested. Even people in monogamous relationships should be tested and should know their partner’s status.What is an HIV test? When HIV enters the bloodstream, it begins to attack certain white blood cells known as CD4 cells. The immune system then produces antibodies to fight off infection. When you take an HIV test, doctors are actually looking for the presence of these antibodies, which confirm that HIV infection has occurred. Why should I get tested? Early diagnosis is crucial in preventing life-threatening health conditions and combating the spread of HIV. Knowing your status will allow you to take steps to protect your health and the health of others. If you know you are HIV-positive and pregnant, you can take medications and other precautions—such as refraining from breast-feeding— to significantly reduce the risk of infecting your child.Am I at risk? Anyone can become infected with HIV, but you are at greater risk if you:Have ever shared injection drug needles and syringes or “works.”Have ever had unprotected vaginal, anal, or oral sex with multiple sex partners, anonymous partners, or men who have sex with men.Have ever been diagnosed with or treated for hepatitis, tuberculosis (TB) or a sexually transmitted disease such as syphilis.Exchanged sex for drugs or money.Received a blood transfusion or clotting factor between 1978 and 1985.Have had unprotected sex with someone who would answer yes to any of the above questions.If you are unsure of a sexual partner’s risk-taking behavior or if you or they have had many sex partners, you are at greater risk of infection.The CDC recommends that all pregnant women be screened for HIV. In the U.S., mother-to-child HIV transmission is highly preventable if the mother begins treatment before or during childbirth.Can’t I tell whether I’m infected without getting tested? No. The only way to know for sure is to be tested. Within a few weeks after infection with HIV, some people may develop temporary flu-like symptoms or persistent swollen glands, but many people feel healthy for a decade, and some for even more. Unfortunately, HIV- infected people who look and feel perfectly healthy can still transmit the virus to others. When and how can I get tested? Most people develop detectable HIV antibodies within three months of infection, the average being 20 days. In rare cases, it can take 6-12 months. For this reason, the CDC recommends testing six months after the last possible exposure, i.e, unprotected vaginal, anal, or oral sex, or sharing needles. You can be tested at your doctor’s office, local health department, hospital, and sites specifically set up to provide HIV testing. All HIV test results are confidential and can only be shared with people authorized to see your medical records. Anonymous testing sites allow you to get tested without giving your name.It is important to seek testing at a place that also provides counseling about HIV and AIDS. Counselors can answer questions about behavior that may put you at risk of contracting or transmitting HIV and suggest ways you can protect yourself and others in the future. They can also help you understand the meaning of the test results and refer you to local AIDS-related resources.The CDC provides a national database of HIV testing sites (see sidebar).What types of HIV tests are available? Several HIV antibody tests are used today. The most common are blood and oral fluid tests. Unlike most testing methods, which can take anywhere from three days to several weeks, rapid HIV testing offers results in 20 minutes to an hour. Although these tests are very accurate, all positive HIV results must be confirmed with a follow-up test before a final diagnosis of infection can be made

HIV TREATMENT

Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS or Aids) is a set of symptoms and infections resulting from the damage to the human immune system caused by the human immunodeficiency virus (HIV). This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk.[This transmission can involve anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.AIDS is now a pandemic. In 2007, an estimated 33.2 million people lived with the disease worldwide, and it killed an estimated 2.1 million people, including 330,000 children. Over three-quarters of these deaths occurred in sub-Saharan Africa, retarding economic growth and destroying human capital. Most researchers believe that HIV originated in sub-Saharan Africa during the twentieth century.AIDS was first recognized by the U.S. Centers for Disease Control and Preventio in 1981 and its cause, HIV, identified by American and French scientists in the early 1980s.Although treatments for AIDS and HIV can slow the course of the disease, there is currently no vaccine or cure.

MRI Scans

Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord.

During the scan, you lie on a table that slides inside a tunnel-shaped machine. Doing the scan can take a long time, and you must stay still. The scan is painless. The MRI machine makes a lot of noise. The technician may offer you earplugs.

Before you get a scan, tell your doctor if you

  • Are pregnant
  • Have pieces of metal in your body. You might have metal in your body if you have a shrapnel or bullet injury or if you are a welder
  • Have electronic devices in your body, such as a cardiac pacemaker

DNA sequence?

A DNA sequence or genetic sequence is a succession of letters representing the primary structure of a real or hypothetical DNA molecule or strand, with the capacity to carryinformation as described by the central dogma of molecular biology.
The possible letters are A, C, G, and T, representing the four nucleotide bases of a DNA strand — adenine, cytosine, guanine, thymine — covalently linked to a phosphodiesterbackbone. In the typical case, the sequences are printed abutting one another without gaps, as in the sequence AAAGTCTGAC, read left to right in the 5' to 3' direction. Short sequences of nucleotides are referred to as oligonucleotides and are used in a range of laboratory applications in molecular biology. With regard to biological function, a DNA sequence may be considered sense or antisense, and either coding or noncoding. DNA sequences can also contain "junk DNA."
Sequences can be derived from the biological raw material through a process called DNA sequencing.

Microbiology In Medicine

is the study of microorganisms, which are unicellular or cell-cluster microscopic organisms.[1] This includes eukaryotes such as fungi and protists, and prokaryotes. Viruses, though not strictly classed as living organisms, are also studied. In short; microbiology refers to the study of life and organisms that are too small to be seen with the naked eye.

Microbiology is a broad term which includes virology, mycology, parasitology, bacteriology and other branches. A microbiologist is a specialist in microbiology.

Microbiology is researched actively, and the field is advancing continually. We have probably only studied about one percent of all of the microbe species on Earth.Although microbes were directly observed over three hundred years ago, the field of microbiology can be said to be in its infancy relative to older biological disciplines such as zoology and botany.
