Cystic fibrosis, is also known as mucoviscidosis, is a genetic disorder that affects mostly the lungs but also the pancreas, liver, kidneys, and intestine. Knowing that Cystic fibrosis is a disease that can cause a lot of trouble in your body if untreated. Cystic fibrosis has three main aspects is it important to know. The first is how Cystic fibrosis is caused in the human body. Second, is how the disease affects the human body. Last, is how do you treat this disease that has entered the human

Chemistry P.5 11/1/2015 The Study of How Microorganisms Grow on different Surfaces Research When people think of microorganisms, they think of dangerous viruses that kill people. But most microorganisms are harmless, some even help humans. Some bacteria produce antibiotics, some live in animal guts, they convert nitrogen into better form, and some break down organic matter.(Brian Speer, 1994). Studying how microorganisms grow on different organic surfaces helps people stay safe from the harmful

The immune system can be divided into two components, a primary innate generalised system and a secondary specialised response. It is the integration of these two systems which can eliminate harm provoked by an invader. The innate response includes multiple physiological and anatomical barriers, including unbroken skin, low pH conditions found on the skin and in the stomach, mucociliary clearance, temperature as well as a few more which all aid in the maintenance of an antimicrobial environment

Contaminated water contains biological microorganisms such as bacteria, fungi, and viruses. Silver nanoparticles are used conventionally as an antimicrobial compound to exhibit multi-interactional activity to fight bacteria. Inevitably, low concentration of silver compounds will remain in the environment. For example values of accumulated silver nanoparticles for surface water, American soil, sludge, , Sewage Treatment Plant (STP) effluent, STP sludge, and sediment were reported 0.088 µg/L/year, 6

Methodology Glucocorticoids Influence on CFTR Because chloride is a major component in the fluid that is secreted from pulmonary epithelial cells, it plays an essential role for the development of fetal lungs. It was previously found that as birth approaches, CFTR levels decline sand cortisol levels increase. Which is why this study investigates the effect of glucocorticoids on the chloride channels in the lungs. In this procedure, fetal distal lung epithelial (FDLE) cells were isolated from

CRISPR has seemingly endless application possibilities and can be used to make more than double‐strand breaks near a 5′‐NGG‐3′ PAM. Researchers have some reservations regarding the Cas9 enzyme for therapeutic usage because it cannot always make precise edits without making unintended and potential lethal cuts. In 2013 Cho worked to overcome this hurdle in human cells. The strategy Cho used to enhance Cas9 specificity was to use two different Cas9 enzymes that each cut a single stand of the DNA.

mucoproteins that quickly forms within minutes of being detached from the tooth surface. The next step is biofilm maturation where the biofilm forms in layers. Microorganisms grow and colonize on the growing pellicle. There are many morphologic forms of bacteria in the biofilm, but in the first few days Gram-positive cocci and rods dominate. The length of time that the biofilm is composed primarily of cocci differs depending on if the patient is a slow biofilm former or a fast biofilm former. Slow biofilm

Cystic Fibrosis Cystic fibrosis changes the cells that produce mucus, sweat, saliva and the digestive secretions, resulting in thick and tenacious secretions. The thick secretions cause obstruction of airway, ducts and passageways. The mutation of Chromosome 7 and transmission that follows an autosomal recessive pattern has been isolated to the genetic defect that leads to cystic fibrosis (Story, L. (2018). Cystic fibrosis is an autosomal recessive disorder most commonly inherited disease in

The objectives of the experiments performed in the past three weeks were to induce mutagenesis in the E.coli K-12 strain W3110 through short ultra violet light (UV). This particular strain of E.coli lacked photolyase (phr) and the uvr system, which are non-mutagenic repair mechanisms. A survival curve was constructed based off various irradiation times and number of viable cells obtained. Mutant strains were then isolated and purified on MacConkey (MAC) plates to rule out false positives. During
