I. Introduction The problem While DNA profiles can be obtained from evidentiary swabs, forensic science is currently deficient in the methods to determine the tissue source of the DNA. While proper confirmatory tests exist for biological fluids such as semen1,2 and blood3, similar tests for the confirmatory identification of saliva are lacking. Being able to confidently identify the source material of the DNA may help criminal investigators corroborate the claims of an alleged victim or suspect
Compartments in the Body The human body is mostly made up of fluid. There are different types of fluid throughout the body that is required for homeostasis. The fluid in the body is separated by cell membranes and capillary membranes. Fluid is stored in the body in intracellular and extracellular compartments. The intracellular fluid (ICF) make up approximately 66% of fluid in the cells. Inside the cells, solutes such as oxygen, electrolytes, and glucose dissolve for the metabolic process.
only can we provide convenience for others but we also become such a warm-hearted and broad-minded person. In fact, in many cases, you do good deeds for the sake of others, but also for your own sake. Do you know how many germs are in human bodily fluids? Saliva, which is produced in the mucous membrane of the lips, inside of the cheek and tongue is responsible for the transference of many germs and diseases. It's studied that those with less saliva in their mouths can have up to four times more disease
Fluids and Electrolytes Homeostasis is the body’s way to maintain internal stability. Cells require certain conditions to function properly. The ability to produce energy is key to life. Animals eat food and take in liquids that the body breaks down to be used by cells to produce energy. Oxygen is required by cells to convert carbohydrates or sugars into energy. Fluids are responsible for the transportation of nutrients to cells and the transportation of waste products of energy production out of
The name of the over-the-counter medication is Actifed Expectorant. Actifed Expectorant contains 1.25 mg Triprolidine HCL, 30mg Pseudoephedrine, and 100 mg Guaiphenesin HBr.

The label indicates that Actifed Expectorant is used to provide symptomatic relief of upper respiratory tract disorders accompanied by productive cough, which benefit from the administration
When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys. Treatment Choice: Hemodialysis Purpose Hemodialysis is a procedure that cleans and filters your blood. It rids your body of harmful wastes and extra salt and fluids. It also controls blood pressure and helps your body keep the proper balance of chemicals
you need to warm one gram of most other fluids by the same amount. This makes water much better for regulating the temperatures of animals and the environment. Water also has a very high heat of vaporization. Converting one gram of cold water into ice requires 80 Calories of energy. Converting the same amount of very hot water into steam requires 540. The high amounts of energy required to change water from its liquid state make water tend to stay a fluid. The process of freezing water involves slowing
was due to concentrated observation. Many scientists studied wounds and diseases intensely and one scientist in particular, Empedocles, came to the conclusion that that body consists of four main fluids, or humors. These humors were yellow bile, black bile, phlegm and blood. If one of these components was out of proportion in the body, disease occurred. The imbalance was called isonomia, an idea which was also proposed by the Greek scientist Empedocles. Empedocles followed the Pythagorean school of
stands for dilation and evacuation. These are preformed up to the twenty-fifth week of pregnancy, and usually take ten to twenty minutes. The way they are preformed is the woman is given absorbent dilators, which open up the cervix and absorb the fluids. After this is left in overnight the woman then is ready for the evacuation stage. The fetus is easily removed with instruments and suction. In the last trimester of the pregnancy abortions are preformed mainly if the woman’s life is in danger or
century. At that time, physicians thought that disease was a curse caused by the supernatural. It was a common idea that blood carried the vital force of the body and was the seat of the soul. Anything from body weaknesses to insanity were attributed to a defect in this vital fluid. Bloodletting was a method for balancing other fluids in the body and cleansing it of impurities. Shakespeare takes the same knowledge of blood and applies it to “Macbeth” in which the connotations not only foretell one’s
weakened and unable to clean the contaminated fluids he or she is expelling. Now having faced days of extreme fever and fatigue, the person resembles a corpse with an expressionless face, deep-set eyes and total lack of energy. Between the fifth and seventh days hemorrhages appear on the body, often open to bleeding. Additional blood is excreted in the individual's vomit and feces, as well as from the nose, and gums. This prevalence of contaminated bodily fluids has been part of the reason why reason
Euthanasia and the Will to Live The denial of food and fluids to Terri Schindler-Schiavo, the 36 year old Florida woman in a vegetative state since a heart attack, has caused Americans to ponder the fact that any one of them could be in this woman's place for a variety of reasons, like an auto accident, fall, mishap, etc. And most Americans don't want to be treated by their family as Terri is being treated by her husband - being denied food and fluids in order to hasten death. It is appropriate
The Human Nervous System The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed. Neurons live both in and outside the central
interaction of sensory parts of our body. The first are the inner ears, which monitor the directions of motion (such as side to side, back to front, up and down, and turning). Some people may feel dizzy without having to be spinning or turning. This dizziness is sometimes caused by an inner ear problem. Changes of fluids in the semicircular canals of the inner ear are one of the attributing factors of motion sickness. (1). Second, the eyes monitor where the body is in space and also the direction
This sphincter acts like a valve, as it allows food to pass into the stomach but does not permit it to pass back up through the esophagus. The stomach, which is in the essence a large muscle sack, contains three sets of glands which produce gastric fluids. One set produces mucus which coats the food, making it slippery, and it protects the stomach walls from being digested by its own secretions. The second set of manufactures hydrochloric acid, which aids in the "break-down" of foods. In conjuction
Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis
newborns through vaginal birth by an infected mother. This disease is not passed on by indirect contact, such as a toilet seat. ľ Chlamydia trachoma is biologically active in vaginal and penile secretions and fluids. ľ The usual reservoir for C. trachoma is the mucous membranes of the body found in the genital region, throat, and eyes. ľ The etiological agent of Chlamydia is C. trachomatis which has the following general characteristics: obligate intracellular parasite gram negative coccoid bacteria
cells to grow and reproduce. What is AIDS? AIDS (acquired immunodeficiency syndrome) is a disease in which the body's immune system breaks down and is unable to fight off certain infections. When a person is infected with HIV, the virus enters the body and lives and multiplies primarily in the white blood cells. These are the immune cells that normally protect us from disease. How quickly do people infected with HIV develop AIDS? Most people remain without obvious symptoms for 10 to 12 years
Filoviruses. Ebola is contracted very much like HIV: bodily fluids such as blood, vomit, sharing needles, and sexual contact. The only difference is that Ebola can be transmitted from the close contact of an infected person, which is the most common means of infection. This is possible because the Ebola virus has cells on the infected person’s skin. For example, should you touch someone with the virus and then an opening on your body, like your mouth, you can be infected. This is why and how so
find nine sets of beady eyes watching one’s every move. Sherman produced her History Portraits during the late eighties and early nineties, nine of which are displayed at the museum. In her portraits she uses lush fabrics, lavish jewelry, and false body parts to decorate herself in these self-portraits. Her portraits have been know to cause discomfort in the viewers who find the general stereotypes, depicted in her portraits, amusing, yet confusing and terrorizing. Sherman’s Untitled #225 (Blond
