The objectives of hemodialysis are to extract toxic nitrogenous substances from the blood and to remove excess water. In hemodialysis, the blood, laden with toxins and nitrogenous wastes, is diverted from the patient to a machine, a dialyzer, in which the blood is cleansed and then returned to the patient. Diffusion, osmosis, and ultrafiltration are the principles on which hemodialysis is based.

The toxins and wastes in the blood are removed by diffusion—that is, they move from an area of higher concentration in the blood to an area of lower concentration in the dialysate. The dialysate is a solution made up of all the important electrolytes in their ideal extracellular concentrations.

The electrolyte level in the patient’s blood can be brought
under control by properly adjusting the dialysate bath. The semipermeable membrane impedes the diffusion of large molecules,
such as red blood cells and proteins.

Acute bronchitis and pneumonia share many of the same symptoms, and some people with acute bronchitis are at risk for getting pneumonia. Although acute bronchitis usually goes away within a few weeks, pneumonia can be a serious condition, especially in older adults. The following table outlines some differences between acute bronchitis and pneumonia. There are variations in symptoms of both conditions, so if you think you might have pneumonia, always check with your doctor.

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:

Shut the front door: Scientists have finally found the perfect breasts. No, they weren't hiding in the Amazon or roving solo across the Sahara (although we have no doubt there are women in both the Amazon and the Sahara who have magnificent mammaries); it turns out these perfect breasts were hiding in a plastic surgeon's office this whole time! Now, before you get all worked up, the American Society of Plastic Surgeons (ASPS) would like you to know that the super-fake looking plastic breasts of yore are not actually what people think are most attractive now. According to a study published in the Journal of Plastic and Reconstructive Surgery—which involved asking over 1,300 people to look at pictures of naked boobies and rank them by hotness (stop laughing, this is serious research!)—people preferred a more "real" and "normal" look from their silicone, with the ideal breast shape having a 45:55 ratio. People said the best chests have 45 percent of the fullness above the nipple line and 55 percent of the fullness below, in a slightly teardrop shape. Researchers noted this preference remained consistent across gender, racial, and ethnic groups with the 45:55 ratio favored by 87 percent of women in their 30s, 90 percent of men, and 94 percent of plastic surgeons.

Cerebral palsy refers to brain damage that occurs before a child is five years old. Therefore, adults cannot develop cerebral palsy. However, cerebral palsy does not get better or worse with age, so when a child has the condition, he or she will continue to have the condition into adulthood.

A stress ulcer is a single or multiple mucosal defect which can become complicated by upper gastrointestinal bleeding during the physiologic stress of serious illness.

Breast cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. A malignant tumor can spread to other parts of the body. A breast cancer that started off in the lobules is known as lobular carcinoma, while one that developed from the ducts is called ductal carcinoma. The vast majority of breast cancer cases occur in females. This article focuses on breast cancer in women. We also have an article about male breast cancer. Breast cancer is the most common invasive cancer in females worldwide. It accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide, including both males and females, are from breast cancer. Breast cancer rates are much higher in developed nations compared to developing ones. There are several reasons for this, with possibly life-expectancy being one of the key factors - breast cancer is more common in elderly women; women in the richest countries live much longer than those in the poorest nations. The different lifestyles and eating habits of females in rich and poor countries are also contributory factors, experts believe. According to the National Cancer Institute, 232,340 female breast cancers and 2,240 male breast cancers are reported in the USA each year, as well as about 39,620 deaths caused by the disease.
