Opportunities for developing mathematical skills within this topic include calculating areas of circumferences and areas of circles, surface areas and volumes of rectangular blocks and spheres, using ratios, fractions and percentages, plotting two variables from experimental or other data, determining the slope and intercepts of a linear graph, understand that y=mx+c represents a linear relationship, drawing and using the slope of a tangent to a curve as a measurement of rate of change, understanding simple probability and completing a statistical test. Dagenais, R.V.E. These enzymes break down the fat. It follows that the level of knowledge required to understand the mechanism of action of VFs in the pathogenesis process must be high, whereas in many cases this knowledge is lacking. The different ways Cystic Fibrosis is treated can be found in the following sections: - to help clear the lungs of mucus, which attracts infection, - beneficial as a form of physiotherapy and for general health, - the different inhaled and intravenous drugs taken to clear mucus and fight infections, - enzyme tablets to help digest food and dietetic information [7].

The detailed PowerPoint and accompanying worksheets have primarily been designed to cover point 2.16 in AS unit 1 of the Edexcel International A-level Biology specification but also challenge the students on their knowledge of previously-covered topics such as inheritance, protein synthesis and the genetic code as well as making links to the upcoming topics of loci and post-transcriptional changes. ; et al. ; Chan, B.K. 2023; 24(5):4635.

In recent years, there has been a renewed interest in the Western world in phage therapy as an alternative or addition to antibiotic therapy. in 2013 reported an MIC of 25 g/mL against, More specific research analyses 22 pure compounds extracted from different parts of 4 medicinal plants (, All the reported studies indicate that plants and fungi are still nowadays a source with a huge potential for discovering new molecules that are effective in fighting, In conclusion, this review provides an overview of the latest findings on innovative therapies against, For some of the strategies described, positive results have been obtained at the early pre-clinical stages, and it is hoped that these will form the basis for developing these strategies and confirming their efficacy in vivo so that they can reach the clinical trial stage. permission is required to reuse all or part of the article published by MDPI, including figures and tables. 5 Cystic fibrosis is caused by a mutation in the CFTR gene. . * Globular and fibrous proteins using haemoglobin and collagen as examples Romero-Calle, D.; Guimaraes Benevides, R.; Goes-Neto, A.; Billington, C. Bacteriophages as alternatives to antibiotics in clinical care. Following this flow, different ongoing studies are evaluating new synthetic molecules but also poorly-studied phytochemicals, often looking for new sources like marine plants. Prepare for GCSE Biology examinations. ; van Duin, D.; et al. 3.8 (ii): The linkage of genes on a chromosome and sex linkage Floto, R.A.; Olivier, K.N. There are different forms of CF, more or less serious, which can also be identified in a more adult stage of life, comprising about 10% of total cases. Wright, A.; Hawkins, C.H.

We are very short of teaching time so I will abbreviate it but still keep the logical steps which are very well put. Again, the students are guided through the events that lead to the depletion of the apical surface liquid and the cilia being unable to move the viscous mucus. Naomi especially enjoys creating resources that enable students to build a solid understanding of subject content, while also connecting their knowledge with biologys exciting, real-world applications. ; das Neves, R.C. How does cystic fibrosis affect the reproductive system? Some of the key biological topics are covered in topic 2 of the Pearson Edexcel A-level Biology A (Salters Nuffield) course and include the transport of materials across cell membranes, DNA structure and replication, protein synthesis and monohybrid inheritance. ; Wallin, W.A. ; Ford, K.; Harris, K.; Gilmour, K.C. For all these reasons, the identification of new therapeutic strategies that can support or refine the scarce antibiotic options available today is an imperative issue to be addressed. ; Gaillard, J.L.

Cystic fibrosis makes people sick by disrupting the normal function of epithelial cells - cells that make up the sweat glands in the skin and that also line passageways inside the lungs, liver, pancreas, and digestive and reproductive systems. ), are all examples of nanomedicine tools, powerful drug delivery systems with the advantages of high efficiency and specificity and a sustained drug release over time at the target site. * The mechanism of action and specificity of enzymes * The process of DNA replication Shedding X-ray light on the role of magnesium in the activity of. ; Sammartino, J.C.; Poli, G.; Tuccinardi, T.; Beretta, G.; Porta, A.; et al.
