Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate…
Prostaglandins are one group of eicosanoids. They are unsaturated fatty acids derivatives that are involved in the contraction of smooth muscle, the control of homeostatic activities such as, inflammation and body temperature, and many more functions of the body. Prostaglandins are derived from arachidonic acid. The formation of the both the arachidonic acid, then prostaglandin molecules begins with a stimulus to a cell, that activates a membrane enzyme called phospholipase A2. The arachidonic…
fibrosis affects ion transport in epithelial cells b) The CFTR protein regulates the transport of a number of ions; name 2 of these ions. (2 marks) The CFTR protein regulates the transport of Cl- and Na+ c) Explain why a defective CFTR gene could cause Dan to produce very salty sweat. (5 marks) The normal function of the CFTR gene provides instructions for making a protein channel called the cystic fibrosis transmembrane. This protein channel transports chloride ions across the semipermeable…
we can prevent damaging our hair from our heat styling tools we use. Heat is really not the best thing to use on your hair even if you put a heat protectant on before starting or you can put tissue paper as weird as that sounds. Hair is made of a protein called keratin and the hair follicle is what attaches the hair to the skin. There is also something called a hair bulb where there are living cells dividing and growing and blood vessels are the ones that provide for the hair bulb. The blood…
Blood is everywhere, in everyone, in all living animals. The type of blood and what makes it look how it does is all based on its composition. The uses of it are vital to all animals survival as it is the key component to living. Unknown to most, but the blood's composition must be kept at near perfect balance at all time for it to perform all its functions. Blood is a crucial part of an animal's existence. Without it, it could not survive. Blood has numerous types as well as appearances, and…
The test on Taco Bell's meat mix was tested and it was found that about 15% of it was protein. That might not sound like a lot, but for ground beef, it’s right around normal. That is because ground beef is mainly composed of water and fat so that percentage of protein is normal. However, that’s not all that was tested. There were some ingredients that were found in the meat that you would not find in your supermarket meat. One such ingredient is soy lecithin. That is a binding agent so without…
The deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) within organisms can be methylated while proteins can be either methylated or acetylated. The methylation of DNA and RNA is used for alternative splicing used for production of different mRNA molecules resulting in numerous new proteins. One of the molecules believed to perform the methylation is N6A or N6 methyladenosine. Methylation is the most observed modification to mRNA molecules. Methylation of both DNA and RNA ensures…
There are many factors which do affect the growth of nails, but five main important aspects are, age, location on body, hormones, cutting and health. One of the big aspects of the growth of nails would have to be Age, considering we get older every year. Infant nails tend to grow slower than adult nails, although, young children nails grow faster than that of an adult. The Location of the nail depends on the growth, in saying that, fingernails grow much faster than toenails, the difference in…
The researchers of this article studied the GLI3 protein, which is a zinc fingered protein and encoded in humans. It is a copy of GLI family and is translocated in patients who possess the Greig cephalopolysyndactyly syndrome─GCPS. The mutation of the GLI3 protein is shown to cause various disorders such as, Pallister-Hall syndrome and postaxial polydactyl type A. The researchers were trying to demonstrate how a single gene mutation could cause these dissimilar developmental disorders in humans.…
polypeptide remain elevated for 4-6 hours. The secretion of pancreatic polypeptide is stimulated strongly from eating fats and protein. Gastrin is a hormone which is produced by cells known as ‘G’, lining the stomach and the upper small intestine. While eating a meal, Gastrin stimulates the stomach and releases an acid called gastric. This occurs the stomach to break down proteins, that is consumed from eating foods and also take away certain types of vitamins. According to the website Your…
