Background Human chorionic gonadotropin (hCG) is the basis for all pregnancy tests.1 It is mainly produced by the syncytiotrophoblast cells of the placenta during pregnancy and can also be seen in gestational trophoblastic diseases (choriocarcinoma, hydatidiform mole) and testicular germ cell malignancies.1,2,3,7 It has been shown that the hCG produced through the majority of normal pregnancy is a smaller molecule than the hCG produced in choriocarcinomas and malignancies, due to four double sized
If the blood sample contains antibodies specific to that allergen, the antibodies will bind to that allergen. Anti-human radiolabeled IgE antibodies are then added and bind only to the antibodies already bound to the insoluble material. The whole sample is then wThe unbound anti-human antibodies are washed away and the level of radioactivity is proportional to the amount of human IgE present in the blood sample.
In Vitro Fertilization (IVF) is a procedure that offers hope to couples who otherwise are unable to conceive. This process is important to infertile couples because it gives them another chance of conceiving a child. In order for normal pregnancy to occur, an egg is released from an ovary and unites with a sperm in a fallopian tube. However, during the process of IVF, this union occurs in a laboratory after both eggs and sperm have been collected. The fertilized egg is then transferred into the uterus
Medicine, University of Coimbra) The amniotic fluid has several functions, some of them being protecting the fetus physically, providing room for fetal movements, and helping regulate fetal body temperature. The placental membrane, located between the chorionic villi and the placenta, separates maternal blood from fetus blood, allowing oxygen and nutrients to diffuse through the villi walls into the placenta. The placenta is the main structure that keeps the fetus alive during its 9 month development process
Rabbit Genetics The similarity between the physiology of rabbits and humans makes the rabbit a good model for research into human disease. The most prevalent types of rabbits are cottontails and European rabbits. Domestic rabbits are tame assortments of European rabbits. The Californian, Florida White, and New Zealand White are the most common breeds used in research. Until 1912 rabbits were classified as rodents. Scientists discovered that the two types of animals differed in several distinct anatomical
In the current breeding practices, management of the estrous cycle is a common. Breeders want to know when their mare is in one phase or the other and also wants to be able to determine when she will ovulate. Manipulation of the estrous cycle is a practice of breeding management. Manipulation of estrous involves changing the normal cycle through hormone treatments or other methods. Managing and manipulating the estrous cycle allows breeders to have control over the phase the mare is experiencing
Medicines are chemicals which are used to cure, stop or prevent diseases, illnesses and ease symptoms. Some medicines are produced in the laboratory by mixing chemicals, while others are found in nature, such as from plants. With the progression of medicines, doctors have been able to save lives and cure several diseases. Not taking medication can prevent a person from not doing everyday activities and also lead to other health problems. There are many reasons why people do not take medicines which
There a Faint Line on Pregnancy Test? There are many possible reasons why only a faint line appears on a pregancy test: Testing too early. This is one common reason why women get inaccurate results from home pregnancy tests, which detects Human Chorionic Gonadotropin (hCG) levels in the urine. This hormone increases during the early weeks of pregnancy and is detected in the urine. However, taking the test too early can make a difference in how much hormone is present in the urine. A home pregnancy test

Things that are considered steroids or an illegal body building drugs are, Anabolic Steroids, Beta-2 agonists, human chorionic gonadotropin (HCG) , luteinizing hormone (LH), Human Growth Hormone (HGH), Insulin-like growth factors, and insulin (Szumski 13). There are also many types of Anabolic steroids, testosterone, dihydrotestosterone, androstenedione, dehydroean drosterone, clostebol, and nandrolone
Thalidomide Thalidomide is a sleeping sedative (The First Appearance Of Thalidomide, n.d.). The drug was “similar to barbiturates with relatively low known toxicity in adults (Breaking News Thalidomide, n.d.)”. Thalidomide was marketed as safe for pregnant women, who used it to combat morning sickness (The First Appearance Of Thalidomide, n.d.). The drug was developed by West German Pharmaceutical Company, Chemie Grünenthal GmbH, because the company wanted to expand the antibiotics it produced (The
Introduction A molar pregnancy (hydatidiform mole) is a mass of tissue that grows in the uterus after conception. The mass is created by an egg that was not fertilized correctly. The egg then abnormally grows. It is an abnormal pregnancy and does not develop into a fetus. If a molar pregnancy is suspected by your health care provider, treatment is required. What are the causes? This condition is caused by an egg that is fertilized incorrectly so that it has abnormal genetic material (chromosomes)
I Hate Being Pregnant Many women who have looked down at a positive pregnancy test will tell you it 's a life changing, heart pounding moment. Some women might also find it frightening or upsetting. So it’s not very surprising if these women suddenly blurt out “I hate being pregnant!” Why the drama? Blame rising hormone levels. There are certain women who are more sensitive to those shifting hormones than others. I Hate Being Pregnant, Is That a Normal Feeling? It 's normal to have mood swings during
determination of β-human chorionic gonadotropin and transvaginal ultrasound, the majority of ectopic pregnancies were only diagnosed after the break, which often made it an extremely urgent situation. Such situations required immediate and adequate medical attention. The only treatment was then to control the bleeding and remove the products of conception, performing salpingectomy. Today, with the help of methods such as Transvaginal ultrasonography and β-human chorionic gonadotropin are used to make

Neisseria gonorrhoeae Introduction Neisseria gonorrhoeae is the obligate human pathogen that causes the sexually transmitted disease (STD) gonorrhea. This Gram-negative diplococci/gonococci does not infect other animals or experimental animals and does not survive freely in the environment. The gonococcal infection occurs in the upper or lower tract, pharynx, ophthalmic area, rectum, and bloodstream. During the 1980’s gonorrhea was also referred to as “the clap” when public awareness was quite
• Define gestational age compared to developmental age • Explain the trimester system of embryological development • Describe the development on a week by week basis throughout pregnancy from the time of fertilization to birth • Understand the stages of development that are sensitive to abnormalities and are at an increased risk of spontaneous abortions • Define aneuploidy and explain its significance to spontaneous abortions • Define confined placental mosaicism, explain how it occurs and why
Trisomy 21 or more commonly known as down syndrome is a condition in which an individual has a full or partial extra copy of chromosome 21 (What is Down Syndrome?, 2012). It was first described as a disorder in 1866 by doctor John Langdon Down and it is the most common cause of cognitive impairment (Heyn, 2014). Today there are three known types of down syndrome trisomy 21 or called nondisjunction, translocation, and mosaicism. Regardless of the type of down syndrome a child may have, they all have
enzymes. Within a few days of this process the uterus will continually divide , the embryo; Releasing hormones to keep the corpus luteum functioning for a few weeks to allow nourishment and protection to reach and line the uterus. Then membrane like chorionic villi are formed to help with protection. These form an essential organ called the placenta; the connection between mother and embryo. This serves as the embryo’s main source of nourishment.
○ More severe nausea and breast tenderness. ○ The uterus measuring larger than normal for your stage of pregnancy. • Blood tests that detect a higher-than-normal level of human chorionic gonadotropin (hCG). This is a hormone that your body produces in early pregnancy. • Ultrasound exam. This is used to confirm that you are carrying multiples. WHAT RISKS ARE ASSOCIATED WITH MULTIPLE PREGNANCY? A multiple pregnancy puts you at higher
Nelson (2014) defines menstruation as the shedding of tissue and blood from the lining of uterus through a woman’s vagina. The author also states that menstruation acts as an important sign of puberty among females whereby they normally start having menstrual periods between the ages of 11 to 14 years old, around three to five days per cycle. Marshall (2014) studies that when periods come regularly, it is called the menstrual cycle which also implies the changes that occur in a woman’s body to prepare
