In general, pediatric epilepsy consists of transient cardiac events. Adult seizures, particularly those with underlying cardiovascular conditions, pose risk to the cardiovascular system, including cardiac ischemia. Respiratory changes are possible across the lifespan, from infants to older adults. Cardiac function seems to be dependent upon the type of seizure occurring. The majority of complex partial, tonic-clonic and temporal lobe seizures are associated with increased heart rate. This…

Motility and flagellar length were compared in Chlamydomonas reinhardtii before and after deflagellation. The Chlamydomonas were deflagellated by a low pH shock and were observed for flagellar regeneration in 10 minute intervals for 50 minutes. We found the average number of cells that were motile after 50 minutes of flagellar regeneration was 43.80 cells. The difference in motility before deflagellation and after flagellar regeneration was due to flagellar length. Less motility was observed in…

Abstract: Our experiment tests how body positions and body movements affect heart rate. We used 4 different subjects and 3 different trials including our control. For our hypothesis, we theorized that the more movements that a person does, the higher their heart rate will be. After doing this experiment, we found that the more movements and exercises your body does, the more increased your heart rate will become. There could be possible sources of error like any experiments, so this data is the…

Furosemide is a medication known as a loop diuretic (Allen, 2013). A diuretic is a medication which increases the amount of urine that passes out from the kidneys and they are often referred to as water tablets. It works by eliminating water and salt from the body through urination. In the kidneys, salt and water are filtered out of the blood and into the tubules of the kidney to the Glomerulus (Waugh and Grant, 2014), making the filtered fluid into urine (Omudhome, 2014). The sodium, chloride…

Imagine you’re out to lunch with a couple of friends from work when your stomach starts to cramp. Oh no, not now, you start to think. You start looking around the room looking for the closest bathroom. You politely excuse yourself from the table and sprint to the bathroom only to find a line. You’re sweating because of the pain, nauseous, and anxious you’re going to have an accident right here in front of everyone. This is how it can feel for someone suffering from irritable bowel syndrome. The…

angina (Darovic, 2002). The IABP will reduce the resistance to the left ventricular ejection and improve coronary perfusion as well as systemic blood flow (Darovic, 2002). During diastole, the balloon inflates to increase diastolic pressure higher than systole pressure while displacing blood volume equivalent to its inflation volume (Darovic, 2002). IABP will enhance…

system eliminates or keeps the excess or shortage solutes or water. When water intake is not enough, blood volume decreases, blood pressure goes down, and this leads the renin secretion which promotes releasing of angiotensin II for increasing osmotic pressure to stimulate hypothalamus. Also water loss is regulated by ADH with water reabsorption mechanism. When osmotic pressure increased ADH also secreted to promotes absorbing water from the collecting ducts causing the produce of concentrated…

Angiotensin Converting Enzyme (ACE) inhibitors lower blood pressure and produce vasodilation by inhibiting ACE – blocking the conversion of angiotensin I to angiotensin II, key mediators of the Renin-Angiotensin-Aldosterone System (RAAS). RAAS is the main mechanism for controlling BP. Angiotensin II is a vasoconstrictor and works by binding to angiotensin I receptors on smooth muscle – these are joined to a Gq protein and the IP3 signal transduction pathway. ACE usually breaks down bradykinin.…

(BIS), twitch stimulator, invasive central venous (CVP), and arterial pressure monitoring. Intraoperative transesophageal echocardiography (TEE) was considered and made available at the bedside, although it was not utilized due to its interference with the cranial fluoroscopy imaging. Mechanical ventilation using pressure-controlled ventilation (PCV) mode was used throughout the case with the following parameters: peak airway pressure 15 cmH2O, FiO2 0.4-0.6, fresh gas flow 1-1.5 L/min.…

experience a spike in their heart rate and blood pressure. In a recent study on the effects of epinephrine on the heart (Fuenmayor and Gomez 2016) the results showed that when the hormone epinephrine was directly injected into the system there were no harmful effects, however the systolic blood pressure and heart rate of the patient increased to up to 10% higher than the basal reading. This study would…
