DRUGS TO TREAT CANCERS & DRUGS TO TREAT NAUSEA AND VOMITING OBJECTIVES 1. State the rationale for the use of antineoplastic agents in the treatment of cancer. Antineoplastic agents (cell cycle specific or cell cycle nonspecific) target rapidly growing cells – malignant cells rapidly divide (uncontrolled growth) and are unable to repair DNA damage. Also used as adjuvant for post-excision of tumor to prevent recurrence of cancer. 2. Outline the phases of the cell division cycle. G0 Phase:

the use of these toxic chemicals contributes to both air pollution‚ such as acid rain‚ and water pollution. Millions of gallons of these chemicals pour into our waterways each year; the toxicity of the chemicals is long-term and settles into the sediments‚ working its way through the food chain. Further toxicity is generated as both plastic and paper bags degrade. POLLUTANTS PAPER V.S. PLASTIC Paper sacks generate 70% more air and 50 times more water pollutants than plastic bags.

On average‚ 26 million animals are tested every year for commercial and scientific testing in the United States. Animals are tested to develop cures and treatments‚ check safety of human designed products‚ and toxicity of medications. Research on living animals has been done since at least 500BC. Although animal testing is wrong - because it is cruel and humane - there is no need for testing on poor innocent creatures when there are alternative testing methods. 95% of animals used in experiments

SIGNIFICANCE Hepatocellular carcinoma (HCC) is the second leading cause of cancer-death in the world. In 2012‚ 782‚000 people were diagnosed and 95% mortality rate makes it the sixth most common cancer [1]. HCC in early stages is usually asymptomatic. When symptoms do occur they are usually mistaken for other liver diseases. Therefore‚ early diagnosis of HCC is extremely challenging. Surgical resection and liver transplant are the best treatment options for early stage HCC (BCLC stage 0 or A [2])

Animal testing is wrong and cruel. If we didn’t test on animals‚ most people believe that people would start testing on humans. More than 100 million animals are killed in the US for animal testing. Animal testing is any scientific test/experiment that is performed on an animal that is likely to cause the animal pain‚ suffering‚ distress or lasting harm. Animals that undergo these tests are harmed on purpose‚ not for their own good‚ in the end they are likely dead by the end of the test. Animal testing

Vitamin D HW205 Kaplan University Vitamin D is actually not classified as a vitamin. It is considered a prohormone and its active form functions as a hormone. In the earlier years Vitamin D was always associated directly with milk. As the progression of research has shown‚ Vitamin D is prominent in many foods. The most vitamin D rich foods are milk‚ margarine‚ fortified cereals‚ fortified orange juice‚ canned tuna and other fish such as mackerel and salmon‚ and some whole

MLT1: ANTIBIOTIC SENSITIVE LAB Western Governor’s University When antimicrobials are used to treat an infection‚ the antimicrobial used is based on selective toxicity. Selective toxicity is when the agent selected kills or inhibits the bacteria without causing serious harm to the host. The agent must interact with a function or structure of the microbe that is not present or is very different from the host. There are two different types of antimicrobial agents: antibiotics and antimicrobial

They test new drugs by infecting animals with diseases; scientists also poison animals for toxicity testing‚ burn the animal’s bare skin‚ which causes brain damage‚ and also implants electrodes into the brain. For some of these protocols‚ animals could be forced to live without food and water‚ live in long-term social isolation‚ and being separated

The way it is metabolized in various patients can also have an effect on toxicity‚ as well as the sensitivity of the patient. As a whole‚ penicillins as a class are non-toxic (Stewart‚ 1994).
