The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

Nephron Sparing Transcatheter Renal Artery Embolization in Trauma Patient Introduction: Acute renal hemorrhage is a common medical emergency‚ which can lead to hemorrhagic shock and eventual death. Complete nephrectomy is used in emergency surgery and is associated with significant postoperative complications. Employing nephron sparing super-selective Transcatheter renal artery embolization techniques can be used to treat acute renal bleeding disorders eliminating need for exploratory laparotomy

Escaping the firewall with an SSH tunnel Once upon a time the thought of a firewalled‚ cordoned‚ and censored web was enough to send chills up the spine of any internet user. As the years have passed‚ however‚ our sentiment has softened. A completely free‚ decentralized‚ and unaccountable web might sound ideal‚ but in actuality it’s a very tall order for any large‚ centralized institution to successfully manage. As a result‚ the web itself — the backbone — is still free‚ but schools‚ offices‚ ISPs

Coronary Artery Disease‚ also known as Coronary Heart Disease‚ is the most common heart disease. In both men and women‚ it is the leading cause of death in the United States. Coronary arteries carry blood to the heart. CAD is caused by a thickening of these arteries‚ called atherosclerosis. Plaque‚ a substance containing cholesterol and other fatty substances‚ builds up inside the thickened walls of the arteries‚ which slows or blocks blood flow to the heart. In result‚ the heart cannot receive the

1. Procedure Coronary Artery Bypass Graft (CABG) is performed when a patient has disease of the coronary arteries. This is usually caused by atherosclerosis which is clogging of the arteries or hardening by cholesterol of plaque. Coronary Artery Bypass is done to improve the blood flow of the heart. The surgeon bypasses the obstructed artery using a healthy artery that is harvested from another part of the body and placed in the heart to reroute the blood flow around the blocked area.

Types of heart diseases include coronary artery disease‚ cardiomyopath‚ valvular heart disease‚ pericardial disease‚ and congenital heart disease. The most common type of heart disease is coronary artery disease. Coronary artery disease (CAD) is when the arteries that supplies blood for the heart muscle gradually hardens and thickens (artherosclorosis) because of the buildup from salt‚ fat‚ cholesterol

Portal vein pressures are high enough to cause rapid blood loss‚ especially in portal hypertension with oesophageal varies. Pulmonary artery haemorrhage is dark red (venous blood) at around 30 mmHg (4 kPa)‚ while bleeding from the pulmonary veins is bright red (oxygenated). Capillary haemorrhage is bright red‚ often rapid‚ ooze. If it continued for many hours‚ blood loss may become

Investigating arteries and veins Methodology 1. Suspend a ring of artery from a hook on a clamp stand. 2. Use a metre rule to record the length of the ring once the mass carrier has been attached to the free end of the ring. 3. Attach a 10 g mass and record the length of the ring after the mass is added. 4. Remove the mass and record the length of the ring. 5. Repeat steps 2 and 3 using 20‚ 30‚ 40 and 50 g masses. Record the length with and without the masses each time. When comparing

Coronary artery disease is also known as atherosclerosis disease‚ coronary heart disease‚ or ischemic heart disease. It is the most common type of heart disease. It is the leading cause of deaths in the U.S in both men and women. When plaque builds up‚ they harden and narrow your coronary arteries‚ decreasing blood flow to your heart. The lack of blood flow can lead to chest pain‚ shortness of breath‚ or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack
