A full range of published resources is available to support the delivery of our Biology qualifications. My arguments for the abortion of a cystic fibrosis child are that the children that have cystic fibrosis and they are in a womens womb and the parents know they do is I think they should get the abortion because the kid will have a long suffering life and the parents will go through hard times. ; Santos, B.P. What type of allele causes cystic fibrosis? The site of infection may also play a role in the expression of VFs, varying it accordingly [, Despite these limitations, currently, AVT compounds against, To understand bacteria from a pathophysiological perspective, it may be important to obtain information on both the complete sets of causative genetic variants and the complex genegene (or epistatic) interactions [, Among the most recent discoveries, antimicrobial peptides (AMPs) are becoming an increasingly promising weapon against bacterial infections. The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript; or in the decision to publish the results. Tortoli, E.; Kohl, T.A. Students should be encouraged to carry out a range of practical experiments related to this topic in order to develop their practical skills. This deletion causes loss of the amino acid phenylalanine located at position 508 in the protein; therefore, this mutation is referred to as delta F508. * Structure and properties of cell membranes 2.6 (i): Understand the process of protein synthesis (transcription) including the role of RNA polymerase, translation, messenger RNA, transfer RNA, ribosomes and the role of start and stop codons Thakur, A.; Mikkelsen, H.; Jungersen, G.

As well as explaining that this channel allows chloride ions to flow across the apical membrane of the epithelial cells, time is taken to emphasise the importance of its inhibition on the ENaC, which prevents the flow of sodium ions back into the cells. ; Koff, J.L. However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. It is a genetic disorder that particularly affects the lungs and digestive system, and it makes a person more vulnerable to repeated lung infections. In addition to the core practicals detailed below, possible experiments include investigation of the effect of surface area to volume ratio on uptake by diffusion, examination of slides of alveoli to observe the features that aid diffusion into the bloodstream, investigation of osmosis and diffusion across membranes, and investigation of inheritance using, for example, corn ears. Normally, mucus in the lungs traps germs, which are then cleared out of the lungs. Everything that you need to pass A-level Biology.

Mycobacterium abscessus is an opportunistic pathogen that mainly colonizes and infects cystic fibrosis patients’ lungs. About 70% of mutations observed in CF patients result from deletion of three base pairs in CFTR's nucleotide sequence. * The meaning of key genetic terms (This article belongs to the Special Issue, Cystic fibrosis (CF) is one of the most common serious genetic conditions. Cystic fibrosis is classified according to the effect of the mutation on the CFTR protein. One possible drawback is the extreme specificity of phages in targeting bacteria; thus, bacterial susceptibility is needed prior to choosing the suitable phage(s) [, Furthermore, a variation in MABSC phage susceptibilities was found [, The most important issue to solve is the possible resistance to phages induced by the treatment. I am doing this case study so people have an idea of what is cystic fibrosis in detail and what people think of it. Mucus is normally slippery and protects the linings of the airways, digestive tract, and other organs and tissues. The gene codes for a particular protein which allows for the . The Burkholderia cepacia complex (Bcc) is a group of bacteria including opportunistic human pathogens. In CF, the inherited CF gene directs the body's epithelial cells to produce a defective form of a protein called CFTR. AMPs are short polypeptides, generally smaller than 100 amino acids, which are rich in lysin, arginine, and hydrophobic residues, and show antibacterial activity and immunomodulatory properties [, Recent studies demonstrated the efficacy of some AMPs against, For example, RP557 is an AMP, designed with the iterative chemical structure of the human cathelicidin LL-37, that showed a broad-spectrum antibacterial and antifungal activity (, Non-Disulfide-Bridge-Peptide 5.5 (NDBP-5.5) is an amphipathic molecule derived from the, Polydim-I (AVAGEKLWLLPHLLKMLLTPTP) is an AMP isolated from the poison of the Brazilian wasp, Polybia-II (WLKLGKMVIDAL) is another AMP isolated from the poison of the wasp, All the studies regarding the use of AMPs against MABSC [, Organic and inorganic nanoparticles (gold, silver etc. This graph shows the age profile of all patients aged under and above 6 years. 2. When this happens, the persons body can't process or absorb nutrients properly, especially fats. My arguments against the abortion of a cystic fibrosis child are that children with the disease should be allowed to live because they wont have a long live and they should be taken care from professionals. Fang, F.C.
