We have been discussing our plan for Convention Day on April 16. Our topic is nutrition and exercise and our audience will be parents and their children. We plan on dividing into two groups--one group will work with the children and provide them with interactive activities (for example, a hand cleaning or teeth brushing station)  and the other group will work the parents. This is effective as we tailor the presentation to be exciting and beneficial to both groups and the parents will be able to learn free from any distractions. Key terms: Dynein  Desmin Hemidesmosome Dynein - Type of cytoskeleton motor protein that moves towards the minus end of microtubules using ATP and transports cargo such as vesicles, endosomes, and lysosomes. Dyneins are also important in centrosome assembly, in positioning the golgi complex, and for positioning the microtubules during mitosis.  https://upload.wikimedia.org/wikipedia/commons/thumb/2/27/Cytoplasmic_dynein.svg/248p...

Key terms: Actin Troponin complex M line Actin - Thin globular filament with the binding proteins tropomyosin and the troponin complex. This thin protein is involved in muscle contraction via its interaction with myosin. https://www.sigmaaldrich.com/content/dam/sigma-aldrich/life-science/metabolomics/enzyme-explorer/f-actin.gif Troponin complex - Complex of three proteins including tnl, TnC, and TnT bound to actin. Calcium binds to the troponin complex to allow for muscle contraction which moves tropomyosin from the binding site between actin and myosin.  https://www.hypermol.com/images/product_images/original_images/tropomyosin_troponin.png?XTCsid=5d01c310d7f6284214f030e2ff1eafc4 M line  - Region of sarcomere that is the region, which is the center of the A band and consisting of solely myosin fibers.  http://droualb.faculty.mjc.edu/Course%20Materials/Elementary%20Anatomy%20and%20Physiology%2050/Lecture%20outlines/sarcomere.jpg

Key Terms: Matrix Processing Peptidase (MPP) Guidance Complex in Chloroplasts Tim9-Tim10 Complex Dictionary Matrix Processing Peptidase (MPP) - An enzyme in the matrix of mitochondria that cleaves signal sequences at the N terminal from the majority of mitochondrial proteins and deliver preproteins to the mitochondria.  Guidance Complex - Protein complex that is the initial recognition site of transit peptides and directs them to the TOC complex in chloroplasts  Tim9-Tim10 Complex - Complex of Tim chaperones that aid in the transport of hydrophobic precursor proteins across the intermembrane space in mitochondria.  http://jcs.biologists.org/content/joces/120/23/4099/F6.large.jpg

On March 13, our class will present our maternal health PowerPoint. I did research on the role of partners when carrying for their pregnant wives. This is an important topic as pregnancy can be emotionally over-bearing as well as physically demanding. Therefore, it is the partners role to ease the burden of their pregnant wife in order for the pregnant wife to remain calm, with hormone levels in safe fluctuations, and to easily follow with bed-rest when needed. To accomplish this, partners must have good communication with their wife--listening to her emotional and physical concerns and providing verbal and physical comfort. It is important for them to be patient with her. It would be helpful for the partner to research the effects of pregnancy on the wife such as mood swings and other behavioral changes in order for partners to anticipate and expect such changes to occur. Researching the aftermath of birth is also crucial for the parent to prepare for the coming of the newborn into th...
