Canine parvovirus (CPV) enteritis is a common cause of acute, severe gastroenteritis in young dogs. Dogs at greatest risk are less than 6 months of age and either unvaccinated or incompletely vaccinated for canine parvovirus. Dogs vaccinated with over-the-counter vaccines also appear to have a higher incidence of parvovirus likely due to ineffective vaccine or improper use. Early clinical signs of parvovirus enteritis include anorexia, lethargy, diarrhea and vomiting. Parvovirus enteritis has…

glomerular filtration rate causing blood urea nitrogen, creatinine, and uric acid levels to rise; Glomerular damage from the reduced renal blood flow allowing protein to leak across the glomerular membrane; Loss of protein from the kidneys reduces colloid osmotic pressure allowing fluid to shift to interstitial spaces that may result in hypovolemia or generalized edema; In response to hypovolemia,…

Purpose: The purpose of this experiment was to determine the percent of chlorine in an unknown soluble salt through using gravimetric techniques. The unknown salt was dissolved in water and the chloride ions were precipitated using silver nitrate which produced silver chloride. The silver chloride was then separated by filtration techniques and through this the amount of chlorine in the original salt was able to be calculated. It is expected that the chlorine percent will be around 55.95%…

When a person has three thyroid nodules present, they are usually recommended to have a Fine Needle Aspiration (FNA) with a guided ultrasound. Once the sample is collected and sent for testing a cytotechnologist and then a pathologist will interrupt the results. When I was doing my clinical rotations for my certificate in cytology I was told that thyroid FNAs were considered our “bread and butter”. Now, I didn’t realize what that meant at that time in my career, I just thought okay, this…

Opposite charges attract, therefore, cations will be attracted to the soil surface, not anions (like charges repel). This is electrostatic attraction, which will cause cation exchange. Cation exchange is the exchange between the cations held on the soil colloid surface and the soil solution. Since Calcium is a cation (Ca2+), this will be attracted to the anions. Furthermore, because Calcium is a divalent cation, it will be held more strongly than a monovalent cation (i.e. Na+). A change in the…

The salts aggregated into a colloid state as small molecule, and with added urate they increase in size. Ammonium ions are the most prone to become flakes and leave the colloid suspension causing buildup of aggregates that obstruct the urinary tract. The article found that dietary purine helps to increase the amount of uric acid being excreted. These…

Jennifer Datus Anatomy and Physiology II Essay Questions Test 2 Professor Vernet 1. The beginning of the cardiac cycle starts with deoxygenated blood from the systemic circulation entering the heart into the right atrium from the superior and inferior vena cava. A chamber of the heart beats because of the electrical impulses located around areas of the heart that travel across the heart which allows the muscles to contract.The SA node located in the right atrium is also known as the pacemaker…

1. Describe two scientific theories relating to the evolution of the chemicals of life A scientific theory is an explanation based on observations, reasoning and experimentations, especially one that has been tested and confirmed as a general principle helping to understand, explain and predict natural phenomena. A scientific theory must be based on careful and rational examinations of the facts. There are 5 major theories that account to the evolution and origins of chemicals of life. However…

The scientific investigation of colloid sand their properties was reported by Faraday (1857) in his experiments with gold. He used the term “divided metals” to describe the material which he produced. Zsigmondy (1905)describes the formation of a red gold sol which is now understood to comprise particles in the 10 nm size range. Throughout the last century the field of colloid science has developed enormously and has been used to produce many materials…

particular procedure, and stored in the blood bank, them transfused to the patient when is necessary. Acute normovolaemic hemodilution is when blood is collected right before a procedure and the blood volume collected is restored as crystalloid or colloid. After the procedure is completed, the blood is then transfused back to the patient after achieving…
