Though cis-platin is highly effective‚ its counterpart trans-platin is counterintuitively not (7). Trans-platin is highly reactive with the environments that lead to reaching the DNA‚ and this reactivity results in the totality of the administered compound becoming deactivated prior to reacting with the DNA (9). Also the DNA lesion caused by cis-platin on the 1‚2 intrastrand crosslinks between adjacent purines is an act that trans-platin cannot do when looking from a stereochemical perspective (9)

of the cancer cells. Therefore‚ the doctors have more time to run more tests. The THC in the plant can help reduce the size of tumors in brain cancer and reduces neuronal damage. Cannabinoids inhibit cancer cell proliferation‚ induce cancer cell apoptosis and impair tumor angiogenesis in breast cancer! Also the cannabinoids decrease cancer cell invasiveness. Ingesting hemp oil can also cure cancer because when the THC connects to the CB1 or CB2 cannabinoid receptor site on the cancer cell‚ it causes

Atherosclerosis is a type of cardiovascular disease where the arterial walls become thickened and hardened due to an excessive build up of fat‚ cholesterol and other substances in the inner lining of arteries forming plaque. Atherosclerosis typically begins in early adolescene and progresses with age.To date‚ the exact cause of atherosclerosis still remains unknown. However‚ there are several risk factors include age‚ gender‚ racial factors‚ family history‚ high blood pressure‚ high cholesterol‚

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Atrial fibrillation is an irregularity in the atria’s electrical impulses‚ causing a disorderly and rapid rhythm. Paroxysmal atrial fibrillation (also termed intermittent atrial fibrillation) is occurrences of AF that spontaneously halt within 7 days of starting. Episodes of AF can last from a few seconds up to a few days in Paroxysmal atrial fibrillation. The sinoatrial (SA) node is the dominant pacemaker of the heart. Located

Most people with peptic ulcers have these bacteria living in their gastrointestinal (GI) tract. Helicobacter pylori release a toxin that promotes mucosal inflammation and ulceration. Helicobacter pylori also cause apoptosis and causes DNA damage in gastric epithelial cells. When apoptosis occurs and DNA damage occurs‚ inflammation occurs when substances enter the stomach that is inflamed and causes irritation of the stomach lining. Too much irritation of the lining then leads to ulcers developing.
