Biomedical Science with a Sandwich Year - BSc (Hons)

This course will provide an introduction to biomolecules in living matter. The simplicity of the building blocks of macromolecules (amino acids, monosaccharides, fatty acids and purine and pyrimidine bases) will be contrasted with the enormous variety and adaptability that is obtained with the different macromolecules (proteins, carbohydrates, lipids and nucleic acids). The nature of the electronic and molecular structure of macromolecules and the role of non-covalent interactions in an aqueous environment will be highlighted. The unit will be delivered though lectures, formative practicals and related feedback sessions to ensure students fully understand what is expected of them. Short tests (formative assessment) will be used throughout the unit to test students' knowledge and monitor that the right material has been extracted from the lectures.

This course aims to introduce the 'workers' present in all cells – enzymes, and their role in the chemical reactions that make life possible.

The fundamental characteristics of enzymes will be discussed – that they are types of protein that act as catalysts to speed up reactions, or make unlikely reactions more likely. Methods for analysis of enzymic reactions will be introduced (enzyme kinetics). Control of enzyme activity, and enzyme inhibition will be discussed.

Following on from this the pathways of intermediary metabolism will be introduced. Enzymes catalyse many biochemical transformations in living cells, of which some of the most fundamental are those which capture energy from nutrients. Energy capture by the breakdown (catabolism) of complex molecules and the corresponding formation of NADH, NADPH, FADH2 and ATP will be described. The central roles of the tricarboxylic acid cycle and oxidative phosphorylation in aerobic metabolism will be detailed. The pathways used in animals for catabolism and biosynthesis (anabolism) of some carbohydrates and fat will be covered, as well as their control. Finally how humans adapt their metabolism to survive starvation will be discussed.

This course will expose students to key themes and experimental techniques in molecular biology, genetics and eukaryotic cell biology illustrated by examples from a wide range of microbial and mammalian systems. It will cover basic cell structure, and organisation of cells into specialized cell types and complex multi-cellular organisms. The principles of cell cycle and cell division will be outlined. The control of all living processes by genetic mechanisms will be introduced and an opportunity to handle and manipulate genetic material provided in the laboratory. Monitoring of students' knowledge and progress will be provided by a multi-choice test and the laboratory report, with feedback.

The module deals with the molecular mechanisms of gene expression and its regulation in organisms ranging from viruses to man. This involves descriptions of how genetic information is stored in DNA and RNA, how that information is decoded by the cell and how this flow of information is controlled in response to changes in environment or developmental stage. Throughout, the mechanisms in prokaryotes and eukaryotes will be compared and contrasted and will touch on the latest developments in how we can analyse gene expression, and what these developments have revealed.

The cell is the fundamental structural unit in living organisms. Eukaryotic cells are compartmentalized structures that like prokaryotic cells, must perform several vital functions such as energy production, cell division and DNA replication and also must respond to extracellular environmental cues. In multicellular organisms, certain cells have developed modified structures, allowing them to fulfil highly specialised roles. This module reviews the experimental approaches that have been taken to investigate the biology of the cell and highlights the similarities and differences between cells of complex multicellular organisms and microbial cells. Initially the functions of the cytoskeleton and certain cellular compartments, particularly the nucleus, are considered. Later in the unit, the mechanisms by which newly synthesised proteins are secreted or shuttled to their appropriate cellular compartments are examined.

A placement typically is a 9-12 month internship with a commercial or public sector or charity organisation which provides opportunities for the student to develop graduate level subject-specific and generic employability skills. Choice of placement by student will be guided and facilitated at UoK with the learning outcomes listed above in mind. It is requested by UoK that the student be closely guided in work (usually with a named supervisor) involving specialist training. Placements are expected to have a scientific research focus and incorporate a project element that may be written up as a scientific report, however, the specific type of work undertaken may vary significantly from placement to placement. The research project should occupy not less than thirty percent of the sandwich year.

Early in the Autumn term, projects are assigned to students by the project co-ordinator (a member of academic staff), where possible in accordance with student choice. Students then meet with their project supervisor to discuss the objectives of the project and obtain guidance on background reading. During the Autumn term students write a brief formative literature review on the project topic providing them with a good background before embarking on the project work.

The main project activities take place in the Spring term. Students taking laboratory projects spend 192 hours (24 hours per week for 8 weeks) in the lab planning, carrying out and documenting experiments. A further 108 hours are allowed for background reading and report writing. There are informal opportunities to discuss the project work and relevant literature with the supervisor and other laboratory staff. Formal meetings may be arranged at the discretion of the student and supervisor. Students undertaking non-laboratory projects are based in the library or, occasionally, in the laboratory; they are expected to dedicate 300 hours to their project work. Non-laboratory students are strongly encouraged to meet with the supervisor at least once a week to discuss progress and ideas and to resolve problems. At the end of the formal project time, students are allowed time to complete the final project report, although they are encouraged to start writing as early as possible during the Spring term. The supervisor provides feedback on content and style of a draft of the report. In addition, students are expected to deliver their findings in presentation lasting 10 minutes with 5 minutes of questions.

Organisation and Content:

Projects are designed by individual members of staff in keeping with their research interests and fall into one of four categories:

• Wet/Dry Laboratory and Computing: practical research undertaken in the teaching laboratories, or on computers followed by preparation of a written report.

• Dissertation: library-based research leading to production of a report in the style of a scientific review.

• Business: development of a biotechnology business plan.

• Communication: similar to dissertation projects but with an emphasis on presenting the scientific topic to a general, non-scientist audience.

Insulin signalling pathway and Target of Rapamycin (ToR) pathway

Organisation of pathways and the molecules involved, how they were discovered to be implicated in lifespan and ageing, ways of modelling and studying their molecular detail in animals e.g. genetic/ epistasis analysis

The processes downstream of these pathways that allow them to control lifespan/ageing e.g. stress resistance, autophagy, reduced translation, enhanced immunity etc…

Cross-talk between pathways.

Dietary restriction, lifespan and ageing

How dietary restriction works in different organisms, what signalling pathways and processes it affects.

Diseases of ageing

What these are e.g. Alzheimers, Huntington's

Overview of 'normal ageing’ associated processes e.g. muscle weakening.

How they can be studied in model organsims and the importance of ageing research for treating these disorders.

Ethics of ageing research

Pros and cons of studying ageing with a goal of extending human lifespan e.g. insurance, health system, social, psychological implications.

Workshop 1: Group discussion of key ageing research paper(s) (small groups).

Workshop 2: Data analysis session (whole class or 2-3 groups).

Workshop 3: Overview of the module in preparation for revision/exam (whole class).

This module focuses on the endocrine system, which in conjunction with the nervous system, is responsible for monitoring changes in an animal's internal and external environments, and directing the body to make any necessary adjustments to its activities so that it adapts itself to these environmental changes.

The emphasis will be on understanding the underlying principles of endocrinology, the mechanisms involved in regulating hormone levels within tight parameters in an integrated manner and the central importance of the hypothalamic-pituitary axis.

During the lectures each major endocrine gland or functional group of glands will be explored in turn and specific clinical disorders will be used to illustrate the role of the endocrine organs in the maintenance of whole body homeostasis. The systems studied will include the following: thyroid gland, parathyroid gland and bone metabolism, adrenal gland, renal hormones (water and salt balance), pancreatic hormones, gut hormones and multiple endocrine neoplasia, gonadal function and infertility.

Consideration will be given to the methods available for the diagnosis of specific endocrine diseases, including the measurement of electrolyte and hormone levels, and the role of dynamic testing.

The role of the endocrine system in integrating metabolic pathways will be emphasised throughout the module and particular scenarios such as infertility, diabetes mellitus.

This module is designed to provide students across the university with access to knowledge, skill development and training in the field of entrepreneurship with a special emphasis on developing a business plan in order to exploit identified opportunities. Hence, the module will be of value for students who aspire to establishing their own business and/or introducing innovation through new product, service, process, project or business development in an established organisation. The module complements students' final year projects in Computing, Law, Biosciences, Electronics, Multimedia, and Drama etc.

The curriculum is based on the business model canvas and lean start up principles (Osterwalder and Pigneur 2010) on designing a business plan for starting a new venture or introducing innovation in an established organisation.
