Watching the film Outfoxed one would think that, yes Fox News is extremely bias. Their tactics of promoting their slogan of fair and balance news is far from being true. I completely agree with the claim that Fox News with their political bias is a danger to American society. Although I believe that claim could have been better supported by adding the news coverages from all the other networks, and showing statistics on the decisions of the public based on the given news by other networks in…

ESPN started with just two men when one, Bill Rasmussen lost his job as communications director for the New England Whalers in 1978. Bill’s dream, along with his son Scott was to change the way the news industry operated, and they did just that by creating the first 24-hour network, and the first to exclusively air sports news. The very first show to air was on September 7th, 1979, live from the ESPN studio. In 1983 they began to distribute programming internationally. After discovering that it…

of what the world consists of. Instead, this group also known as “Fox News” is exclaimed to set a “smoke and mirrors” illusion. During the film, different officials, state and show explicit evidence and facts about the misconduct of the Fox News channel. The documentary begins by introducing Rupert Murdoch, a wealthy businessman that bought the Fox station in 1985. Fox began as an affluent news provider that Murdoch negatively turned into a station that tributes the importance of Ronald Reagan,…

#4 Case 1 1. Procardia XL is also known as nifedipine, which belongs to a class of drugs called calcium channel blockers that prevent the transmembrane influx of calcium into both cardiac muscle and vascular smooth muscle. The formulation of nifedipine is an extended release tablet that is designed to provide a constant level of drug over a 24-hour period. Within the class of calcium channel blockers, nifedipine belongs to the dihydropyridine variety. 2. Dihydropyridines have a profound effect…

L-type channels is to control calcium entry into the cell. This leads to stimulation of smooth muscle and cardiac myocytes contraction. Calcium channel antagonists prevent the opening of L-type channels in excitable tissues in response to depolarisation – as a result the limit the increase of Ca2+. L-type channels control the upstroke of action potential in the SA and AV nodes and also mediate phase 2 of ventricular action potential. Thus, by blocking the entry of calcium into cells calcium…

between oxygen supply and oxygen demand in the heart. The three classes of antianginal drug are organic nitrates, beta-adrenergic blockers (beta-blockers), and calcium channel blockers." 1. Organic nitrates 2. Beta-adrenergic blockers (also called beta-blockers) 3. Calcium channel…

excitation of a skeletal muscle fiber by a nerve signal. The nerve signal must be sent to the neuromuscular junction to open the voltage-gated calcium channels. Just like in a muscle fiber, the neuron must reach threshold potential before the action potentials can be propagated down the neuron. After the threshold potential is reached, voltage-gated sodium channels open causing sodium to rapidly move into the cell. This is called depolarization because voltage inside the cell becomes more…

diagnosis: Diagnosis is usually made from patient history and find other causes of heart failure. (The signs and symptoms for heart failure dyspnea, fluid retention, peripheral edema, nausea.) The most helpful tools of the diagnosis is echocardiogram. The chest x-ray identify the heart enlargement. Character’s : • Heart failure symptoms, including unexplained right heart failure • Arrhythmias • Conduction abnormalities • Thromboembolic events • angina pectoris managements : Heart-Healthy…

Kathryn R. is a 57-year old woman who has a history of mitral valve prolapse with regurgitation and high blood pressure. Mitral valve prolapse with regurgitation is a condition where the mitral valve doesn’t close properly, leading to regurgitation where the blood leaks backwards when the heart beats. The blood is then unable to reach the rest of the body, pushing the heart to pump harder in order for the blood to go to the body. Kathryn’s hypertension is a risk factor that has lead to her…
