Sweat, Exercise, and Sports Drinks

Animals, including humans, generate heat, even at rest, due to their metabolic activity. Some of this heat is lost to the environment by radiation, convection, conduction,and in terrestrial animals the vaporization of water. Evaporation has a significant cooling effect because about 2.5 kJ of heat is given up for every gram (ml) of water lost

Glycogen storage disease

The glycogen storage diseases are a set of inherited disorders of glycogen metabolism, not all of which result in glycogen accumulation, as the name might suggest. The symptoms of the glycogen storage diseases vary, depending on whether the affected tissue is liver or muscle or both. In general, the disorders that affect the liver cause hypoglycemia (too little glucose in the blood) and an enlarged liver. Glycogen storage diseases that affect primarily muscle are characterized by muscle weakness and cramps. The incidence of glycogen storage diseases is estimated to be as high as 1 in 20,000 births, although some disorders are not apparent until adulthood.

Fats,Diet, and Heart Disease

Years of study have established a connection between elevated LDL levels and atherosclerosis this indicates that certain diets contribute to the formation of fatty deposits that clog arteries and cause cardiovascular disease.

Considerable research has been devoted to showing how dietary lipids influence serum lipid levels. For example, early studies showed that diets rich in saturated fats increased blood cholesterol (that is, LDL), whereas diets in which unsaturated vegetable oils replaced the saturated fats had the opposite effect. These and other findings led to recommendations that individuals at risk for atherosclerosis avoid butter, which is rich in saturated fat as well as cholesterol, and instead use margarine, which is prepared from cholesterol free vegetable oils.

What causes the inflammation of the spinal cord

What is meningitis

This is the inflammation of the spinal cord and brain. It starts when the protective membrane across the brain and spinal cord referred to as the meninges becomes infected. There are many types of meningitis but the bacterial and viral meningitis are the most common.

The bacterial meningitis
Bacterial meningitis is very severe and can be lethal. Death can occur in few hours. Many people get well from meningitis.

What causes tumor of the uterus?

Leiomyomata are the most common tumors of the uterus, occurring most commonly in women of reproductive age, particularly in the 30s and 40s. The impact of fibroids on fertility depends on the parameters of location, number, and size.

Types of leiomyomata include

1. subserosal

2. intramural

3. submucosal varieties.

Submucous myomas, by virtue of their mass effect and inhospitable surface area, have been clearly associated with infertility and with pregnancy loss.

These myomas appear as rounded masses that bulge to varying extents into the endometrial cavity, and the overlying endometrium may be atrophic, congested, ulcerated, or hemorrhagic. Because of their intracavitary location, submucosal fibroids may be effectively removed via a hysteroscopic approach. Sonohysterography and hysteroscopy are equivalent in the detection of sub-mucosal myomas. Whereas SIS offers the advantage of allowing measurement of the overall dimensions of the lesion, office hysteroscopy may afford the removal …


scientific history

In the 1840s, chloroform was found to produce general anesthesia, opening new possibilities for careful surgery with a patient who is unconscious and relaxed.
Chloroform is toxic and carcinogenic, it was soon abandoned in favor of safer anesthetics, such as diethyl ether. A less lethal halogenated analgesic is a blended alkyl halide, which passes by the exchange name Halothane. Ethyl chloride is frequently utilized as a topical soporific for minor systems. When sprayed on the skin, its evaporation (bp 12 °C) cools the area and enhances the numbing effect.

What is anesthesia? Anesthesia is a way to eradicate the pain amid a surgery or by utilizing a medication called anesthetics. It can help to control breathing, blood pressure, the movement of blood, and heart rate.

Fact in 2018 about Carbon Monoxide Poisoning to health

Carbon monoxide is a scentless, gas that kills. Where is CO found?

CO is found in exhaust created at whatever time you consume fuel in autos or trucks, little motors, stoves, lamps, flame broils, chimneys, gas reaches, or furnaces. CO can accumulate inside a building, factory etc and harm individuals who inhale it.

Symptoms of CO 

The most widely recognized side effects that CO can inflict are migraine, dazedness, stomach upset, nausea, chest ache, and disarray. The symptoms of CO are frequently portrayed as "influenza prefer." If you inhale a lot of CO it can make you pass out or even kill you. Before the symptoms are noticed individuals who are resting or under the influence of alcohol can die can die from CO poison.

The Artificial Heart

scientific histroy

The AbioCor self-contained artificial heart, which was first implanted into a patient on July 3, 2001. The outer shell is polycarbonate, and the valves and inner bladder are polyurethane.

Artificial hearts
The heart is an organ that pumps blood around the body system. It has four different chambers: The left and right atrium (this is a chamber for receiving blood). The left and right ventricles (the chamber that pumps blood). Blood in the right ventricle (right part of the heart) is pumped into the pulmonary artery and on to the lungs. Blood in the left ventricle (left part of the heart) is pumped into the aorta and through to the body.

what is health merits/demerits of Erythropoietin (epo)

This is a hormone formed in the kidney that helps in the formation of red blood cells by the bone marrow.

The kidney cells that forms erythropoietin are sensitive to little oxygen levels in the blood that moves through the kidney. These cells produce and liberate erythropoietin when the oxygen level is very little. A little oxygen level may be a sign of a reduced amount of red blood cells (anemia), or molecules that transport oxygen in the body.
