symptoms of stroke

 

A stroke—a decrease in blood flow to the brain due to a clot or bleeding—is a medical emergency. And doctors often say “time is brain,” meaning the quicker you get treatment, the less likely it is that your brain tissue will be permanently damaged. About 80% of strokes are due to a clot (ischemic strokes) and the rest are due to bleeding in the brain (hemorrhagic stroke).

Apa ovarium dan apa kista ovarium?

Ovarium adalah salah satu dari sepasang kelenjar reproduksi pada wanita yang terletak di panggul, satu pada setiap sisi rahim. Setiap ovarium tentang ukuran dan bentuk kenari. Ovarium menghasilkan telur (ovum) dan hormon wanita estrogen dan progesteron. Ovarium merupakan sumber utama dari hormon wanita, yang mengontrol perkembangan karakteristik tubuh wanita seperti payudara, bentuk tubuh, dan rambut tubuh. Mereka juga mengatur siklus menstruasi dan kehamilan. Kista ovarium ditutup, struktur kantung-seperti dalam ovarium yang mengandung zat cair, gas, atau setengah padat. "Kista" hanyalah istilah umum untuk struktur berisi cairan, yang mungkin atau mungkin tidak mewakili tumor atau neoplasma (pertumbuhan baru). Jika tumor, mungkin jinak atau ganas. Ovarium juga disebut sebagai gonad betina.

Ovarian cysts facts

 


What is the ovary and what are ovarian cysts?

The ovary is one of a pair of reproductive glands in women that are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of a walnut. The ovaries produce eggs (ova) and female hormones estrogen and progesterone. The ovaries are the main source of female hormones, which control the development of female body characteristics such as the breasts, body shape, and body hair. They also regulate the menstrual cycle and pregnancy. Ovarian cysts are closed, sac-like structures within an ovary that contain a liquid, gaseous, or semisolid substance. "Cyst" is merely a general term for a fluid-filled structure, which may or may not represent a tumor or neoplasm (new growth). If it is a tumor, it may be benign or malignant. The ovary is also referred to as the female gonad.

How can the physician decide if an ovarian cyst is dangerous?

 

  Ovarian cysts are closed, sac-like structures within the ovary that are filled with a liquid or semisolid substance. Ovarian cysts form for numerous reasons. Pain in the abdomen or pelvis is the most common symptom of an ovarian cyst, but most are asymptomatic.  Most cysts are diagnosed by ultrasound or physical exam. The treatment of an ovarian cyst depends upon its likely diagnosis and varies from observation and monitoring to surgical treatment.

characteristic feature of breast cancer

Breast cancer characteristics



The cancer will also be tested for a number of other characteristics that can help your doctors decide how it is likely to respond to particular kinds of treatment or how aggressive it may be. These include:

Hormone receptivity. These tests determine whether the cancer cells contain estrogen and/or progesterone receptors. Those that do may respond well to hormone therapies that block the production of female hormones in the body. Learn how hormone therapy works to treat hormone-receptive breast cancers.

Tumor-marker testing/immunohistochemistry (IHC). Also known as human epidermal growth factor 2, or c-erB-2, Her2/neu is a protein necessary for normal cell growth. However, some cancers — including some breast cancers — produce too much of this protein.

High levels of HER2/neu often mean that a tumor is more aggressive, and may respond differently to certain cancer treatments. For example, women with high levels of HER2/neu may be good candidates for certain biological therapies. Learn more about biological therapies in breast cancer treatment.

How to avoid heartburn

When it comes to acid reflux, there are certain foods that are almost universally problematic.The best strategy is to avoid them entirely. But unfortunately, they often make up over half of many people’s diets.

In Dropping Acid: The Reflux Diet Cookbook & Cure, authors Jamie Koufman, MD, Jordan Stern, MD, and French master chef Marc Bauer share foods they consider hazardous, based on medical literature and their experience treating thousands of patients.

Chocolate
Bad news for chocolate lovers: Chocolate seems to cause more reflux than any other food. It’s a triple whammy:

1. Chocolate contains caffeine and other stimulants such as theobromine, which cause reflux.
2. Chocolate is high in fat, and fat causes reflux.
3. Chocolate is also high in cocoa, and cocoa causes reflux.

Theoretically, dark chocolate isn’t as bad as high-fat milk chocolate, but let’s face it—all chocolate is bad for reflux.

What is DNA testing?

What is DNA Testing?

DNA is the most powerful tool available for identification in forensic investigations. Because of its ability to link physical evidence found at a crime scene to a single person, it is often referred to as a “digital fingerprint.” This method is so precise that it can ensure pinpoint accuracy, down to one in a billion. And, unlike fingerprints, which can only be found if a suspect touches something, DNA exists in every cell of the human body, from hair and blood to skin and tears, and can be shed or deposited while committing a crime. That means it is often the only means for accurate identification.
DNA databases make it possible for law enforcement crime laboratories to electronically search and compare collected DNA profiles to crime scene evidence. In the United States, the Combined DNA Index System (CODIS) links all local, state, and national databases and contains more than 5 million records. Currently, legislation exists on the federal level and in 29 states, enabling investigators to collect DNA upon arrest for certain felony crimes.
