In one sentence, describe what the following article is about: If you have had one molar pregnancy, your risk of having a second is about 1 2%. Molar pregnancies are also more common in women who are younger than 20 or over 45.Your doctor may suggest waiting a year before trying again to get pregnant. Waiting will allow you to fully recover from the last one and to make sure all of the molar tissue was removed. If you get pregnant too soon, you have a higher risk of having another molar pregnancy. Molar pregnancy occurs due to problems that occur during fertilization and result in nonviable embryos. This means that you cannot prevent or cause it. 0.1% to 0.3% of pregnancies are molar. In a complete molar pregnancy, the genetic material from the mother's egg is lost or inactive and the genetic material from the sperm is duplicated. In a partial molar pregnancy, the father provides twice as much genetic material as normal, even though the genetic material from the mother is still there. This can happen if two sperm fertilize one egg. If you are pregnant and have the following symptoms, you should go immediately to the doctor to get checked. Passing cysts through your vagina. They may be as large as grapes. Bleeding from your vagina during the first few months of pregnancy. The blood may be dark brown or fresh and bright red. Bleeding is usually heavier than it would be with a miscarriage, especially if you wait to be seen by a doctor. Nausea or vomiting. This may be so severe that you require hospitalization. A feeling of pressure or discomfort in your abdomen. If you have had any symptoms of a molar pregnancy, your doctor will examine you for other signs such as: Abnormal levels of the pregnancy hormone HCG, or human chorionic gonadotropin Ovarian cysts A uterus that is expanding too fast for the stage of pregnancy you are in Anemia A raise in blood pressure before 20 weeks Preeclampsia, which is a dangerous condition in which your blood pressure increases and you get protein in your urine. You may have swelling in your feet and legs. A complete molar pregnancy can be seen on ultrasounds as early as eight weeks into the pregnancy. An ultrasound uses sound waves to create a picture of the uterus and developing baby. If you have a complete molar pregnancy, the ultrasound may show that no embryo has developed, there is no amniotic fluid, the uterus is filled with a cystic placenta, or ovarian cysts. If you have a partial molar pregnancy, the ultrasound may reveal that the fetus is not growing properly, there is not enough amniotic fluid around the fetus, and the placenta is thick and filled with cysts.
Summary: Wait to get pregnant if you had a previous molar pregnancy. Learn about molar pregnancies. Watch for symptoms of a molar pregnancy. Get checked by a doctor. Confirm the diagnosis with an ultrasound.

In one sentence, describe what the following article is about: On a male, the front of their heads will have a high, noticeable crown. It will likely look much more prominent and a bit larger than the female angelfish. This feature might be more prominent at maturity, but you may be able to notice it earlier on in the lifespan, as well. This isn't a sure-fire way to tell the difference between the sexes. In some strains of angelfish, this physical difference might not always be present. Female angelfish might have more rounded bodies than males. Female angelfish are also generally a little smaller than male angelfish. If you want to buy pairs to breed, try buying a few smaller angelfish and a few larger angelfish. Once they're mature, you'll more than likely find out you have a few males and a few females. On female angelfish, the line from their dorsal fin to their eyes also tends to be a bit straighter than that of the male's. Sometimes with female angelfish, you might be able to notice a difference when they swim towards you. The shape of their bellies might be a bit bigger or wider than male angelfish. Try looking into the tank and waiting for each of the fish to swim towards the glass. Observe the shape of their bellies from that angle.
Summary: Look for a large crowned head on male angelfish. Check for a smaller, more rounded shape on female angelfish. Watch them as they swim towards you.

In one sentence, describe what the following article is about: A fiber brush is useful because it can easily enter the grooves of the record to remove dirt. Additionally, the type of fiber easily drains static electricity which is responsible for attracting dust. To use, spin the record slowly while holding the brush over the vinyl. Special brushes can be purchased at your local music store or online. Use the brush to clean your records both before and after each record use. Don't forget to clean the dust off of the brush between uses too. Avoid using a T-Shirt or towel as this can damage the surface of your vinyl. There are pre-formulated cleaning products available both online and at local music stores, but you can also make a safe and affordable cleaner at home. Combine distilled water, isopropyl alcohol, and a couple drops of laundry detergent #without fragrance or dyes#, spray onto the vinyl, and use a microfiber cloth to wipe in a circular motion until the vinyl is dry. Combine 12 oz distilled water, 2 oz alcohol, 2 drops free and clear laundry detergent, into a spray bottle. It's important to use distilled water because it doesn't have any minerals that could be harmful to the record. Vinyl record vacuums provide a deeper clean than brushing and cleaning products alone. The vacuum sucks the debris out of the grooves with as little friction as possible. In addition, vacuums are able to apply a thin layer of cleaning fluid which dissolves oils and further protects the record. Each record vacuum is different so consult included with the device to learn to operate the device correctly. As an added bonus, the vacuum also helps to dry the record in an even fashion.
Summary:
Use a carbon fiber brush. Try using a cleaner. Purchase a vinyl record vacuum cleaner.
