All Research

• PM-230 Selected Medical Diagnostic Techniques

  This module looks at the design and operation of a wide range of instrumentation used to make measurements for diagnostic and monitoring of health and disease. The emphasis is on the underlying electrical, mechanical, chemical, optical and other engineering principles together with the advantages and limitations of techniques.

• PM-259 Contemporary themes and techniques in medical sciences

  This module aims to give students an overview of current and emerging themes in medical sciences, both from clinical and laboratory perspectives. This will cover topics generating high media interest, such as the COVID virus and alternative methods of transplantation as well as new laboratory techniques. In addition, the module will be supported by two practical classes for which students will be required to conduct mini-projects based around the identification of patient samples and how these are presented as research cases.

• PM-259C Themâu a thechnegau cyfoes yn y gwyddorau meddygol

  Nod y modiwl hwn yw rhoi trosolwg i fyfyrwyr o'r themâu presennol a'r rhai sy'n datblygu yn y gwyddorau meddygol, o safbwynt clinigol a'r labordy. Bydd yn ymdrin â phynciau sy'n denu sylw sylweddol yn y cyfryngau, megis y firws Zika a dulliau trawsblannu amgen yn ogystal â thechnegau labordy newydd. Yn ogystal, ategir y modiwl gan ddau ddosbarth ymarferol - disgwylir i fyfyrwyr ymgymryd â phrosiectau bach ar sail dadansoddi samplau cleifion, a sut caiff y rhain eu cyflwyno fel astudiaethau ymchwil. Bydd y modiwl hefyd yn cynnwys 'cynhadledd' undydd pan fydd myfyrwyr yn cyflwyno data ac yn cael profiad o awyrgylch cynhadledd ymchwil.
