Josef Skopalík, Ph.D. Biology2022 - FAOB1 BIOLOGY Introduction Short summary of BIOLOGY in next 12 weeks September 2022 Introduction. Microscopy and another visualisation methods Cell – definition, development of cells (bacteria, plant, animal). Eukaroyte / Prokaryote Basic internal structure and bioenergetics of different cells October 2022 Structure of biological membranes - basal cell bioenergetic. Transport of ion and another bioactive compound. Organelles and illness connected to organelles. Organelles and clinical target in organelless. November 2022 Cell signaling and Cell cycle. – clicnical aspect for Cancer and Regeneration medicine Biologie of human immune system. Pathological state in immune systém and basic clinical strategy. Cell division (Types of Division in PROKARYOTE and EUKARYOTE). Mitosis and Meiosis. Gene transcription. Genome. MENDEL genetics. Mutation and cancer October 2022 Modern trends in cell biology and genetics Why medical and pharmaceutical worker need BIOLOGY a CELL BIOLOGY: • We should take not only macroscopical experience and statistic form curative effects from set of patient in previous time • We need also basic idea about structure of tissue and cells and about aktivity of bioactive molecules in this microstructure • Many new pharma-compounds arte tested on cells IN VITRO (Evidence based science – before clincila tests) In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. MAGNIFICATION and RESOLUTION of visualisation machine (microscopes, ultrasound, telescopes…) • RESOLUTION (or sometimes RESOLVING POWERS) is defined as the ability of a microscope (or another machine) to distinguish two close together entities as being separate. An example of resolving power is how well a microcope can show two bacteria as two separated circles. • For example school microscope : 0,1mm distance of bacterias resolve, but 0,01mm long • bacteria which are in contact are visited as on small dot. • RESOLUTIO of microscope - similar to screen defintion of resolution in home TV or PC) • MAGNIFICATION of any optical machine can be defined by two ways: • Standart magnification Anglular magnification (mostly for LENS) Both of them are comparable and recomputable Typical resolution of traditional microscopes Learn!! Will be also in final test ! !! IMPORTANT VOCABULARY of microscope comopnents (will be used in 3 excersise at october !!!) and will also in final test Practical excersise 1 MICROSCOPE Basic aims: 1) Be friendly with school optical microscope. 2) Be prepared to read magnification of objectives 3) Be prepared to focuse the microscope and draw the cell structure vhich is visble in mircroscope For basic bacrkoudn vocabulary: Practical excersise 1 MICROSCOPE Basic aims: 4) Be friendly with recomputing of mm …… um ….. nm (mili … micro … nano meter) 5) Be prepared to tip, which visualization machine produce this scans: 6) Have a idea about resolution of machines Additional very good short movie about tomography: LECTURE 2 Cell and the subcellular structures Prokaryota / Eukaryota Cells from Animal / Human / Bacteria • Medicinal experts should have good overview not only about human cells, but also about another historical cells and viruses (PROKARYOTA) because their interaction with human body is critical for development of many pathologies (flu, diabetic wound, pathology of intestine microorganism, …aerobic or anearobic environment could induce different bacterial aktivity etc) PROKAROYTE vs. EUKAROYTES Prokaryota role in evolution Eukaryota EUKAROYTE: two main group of cells
