American Revolution Essay Example | Topics and Well Written Essays - 500 words - 3

American Revolution - Essay Example The insurgency occurred because of collected complaints which the American individuals had enough of. They were additionally challenging the different demonstrations that had been built up by England and which were to their drawback. A model was the Stamp Act of 1765 which forced that each American was to pay duties to England so as to counterbalance the expenses of running the British Military Organization. There was the cash demonstration of 1764 that denied issuance of lawful delicate cash and this threated to destabilize the mechanical economy. The quartering demonstration of 1765 additionally added to the insurgency as it expected colonialists to house troops from Britain and even gracefully them with their well deserved food. The contention that happened among England and the settlements was fundamentally realized by the provinces conflicts with the principles acquainted with them by their British heads. These guidelines sabotaged them further and kept them from being free and they were worn out and furious about this. They along these lines began with revolts in a portion of the states which were at last replicated and rehashed in the remainder of the provinces and this thusly prompted the transformation which occurred over various years. They were completely contradicted to these approaches and they began joining against the British colonialists as they realized that once join together, they could without much of a stretch get their freedom. The settlements additionally quit giving cash to the British government. The British government had spent the greater part of its assets and even amassed obligation from the war and they required cash from the settlements to recuperate which was not approaching (Morton 41). They began revolting and mass fights to deny the new strategies England was conferring on them henceforth giving trouble to the colonialists. The final turning point was reached in 1763 after the seven year’s war. At this point, enough was sufficient with the abuse and the various Acts and

Cellular neurobiology

Cellular neurobiology This morning I went in early to image neurons on the confocal microscope again, and I was going to take pictures of the lab and our equipment for you guys I wanted to take them when I was in early, so I wouldnt have to explain to all the postdocs what a blog is but I forgot the camera. Hey, Im not a morning person, and I cant remember to do everything when I leave my nice dark cozy apartment at 6:45 AM. At least I did remember to leave Adam a shopping list, so he could go to the store on his lunch hour and get me ingredients for cookies and pie! So I guess instead, Ill talk about what my lab studies generally, and hope you dont notice that there arent any shiny jpegs to go along with my talk. Ive been working in Morgans lab for the last three years, which makes me one of the more senior lab members. Morgans lab is primarily concerned with studying the proteins which make up neuronal structures called dendritic spines. As someone may or may not have ever told you (I know they didnt teach me anything about neurobiology in my high school bio class but maybe things have gotten better over the last five years), neurons talk to one another via chemical signals. One neuron gets excited, and sends an electrical signal to its end which causes little packets of neurotransmitter to be released. The packets of neurotransmitter travel across the synaptic cleft and bind to receptors on the outside of the postsynaptic neuron. Different neurotransmitters bind to different receptors, so at this point everything gets really complicated. But something thats relatively universal is that the receptors are anchored to other proteins, which form a scaffold for the receptors and their associated factors. These scaffolds are located in the spines, and form a line visible on an electron microscope. This is called the postsynaptic density, or PSD. The spines are the hotspots of activity in the postsynaptic neuron; there arent many/any receptors or scaffolds outside spines. Ohmigod, I did not make this figure in Paint. How rude of you to suggest that I did. This is from a paper of Morgans from 2004. As you can see, lots of proteins in spines are binding to each other, and some proteins act as master scaffolds binding many different types of proteins together. These master scaffolds seem to act as liasons to the actin cytoskeleton. This is important, because reshaping of the spines via the cytoskeleton can be shown to have effects on memory-like states. Relatedly, patients with fragile X (a prominent symptom of which is mental retardation) can be shown to have long, skinny spines; most spines in adult neurons are relatively short and have mushroom heads. If you look back at my neuron pictures from last week, youll see that the body of the neuron is yellow (red + green = yellow), but there are lots of little green speckly dots all over the dendrites. (Aside: Dendrite comes from the Greek for tree. If you look at a live neuron in 3-D, youll see that the dendrites do look quite a bit like tree branches.) The reason there are speckly dots is that my protein, which is stained in green, localizes very strongly to the spines. There are approximately a majillion proteins in spines, and each person in my lab is studying a different one, pretty much. Some people are studying kinases (proteins which add a phosphate group to other proteins, generally changing the activity of the other proteins in some way), some are studying scaffolds, and some are studying ubiquitin ligases (proteins which add a small molecule tag to other proteins, causing them to be degraded by the cell). So thats what we do! Questions? 1. Arun asked, Mainly, I was wondering how much social responsibility do you think scientists have and whether that is enough many labs seem to focus on issues which are interesting to scientists but will have no effect whatsoever to the outside world. I have mixed feelings about this personally. As I look through labs in which I could do my thesis, Im drawn to labs studying medically applicable problems blame Professor James and 21A.216 (Dilemmas in Biomedical Ethics), but I would love to do something to help cure diseases, particularly the really devastating stuff like tuberculosis and AIDS. But my personal interests arent necessarily in those areas, and Im certainly no microbiologist. Im reassuring myself for the moment that even areas that dont seem to be relevant to disease can be just a few fortuitous discoveries away from a new therapy. As long as its related to the workings of biological organisms, it is potentially medically applicable. You just have to think a little harder. ;) 2. Nathan asked, Im really interested in neurons, and I was wondering if youve heard of the theory that neuron density is associated with intelligence or comprehension. Is it true that the activity of a neuron is proportional to the length of its dendritic tree? I would say that more accurately, neurons more densely packed with spines will tend to be more active. In a hand-waving way, spine density and spine number are related to intelligence (see again the fragile X example above), but with the strong disclaimer that most studies of this sort are looking at changes in the electrical properties of one type of neuron my lab uses rat hippocampal neurons in a dish in culture, while there are many different types of neurons in your head cross-talking in ways we cant even begin to comprehend right now. Understanding intelligence in a cellular way is far away. 3. Ashley asked, I was wondering, after you get your bachelors degree, are you required to get you masters and then your PhD, or can you start working on your PhD right after getting you bachelors? It depends on your field. In science, you generally go straight from a bachelors program to a PhD program Ill never get a masters degree. In engineering, you generally receive a masters degree before you are eligible to receive a PhD. 4. Anonymous asked, im really interested in being a cheerleader this fall but i dont have any experience :( what should i do to prepare for the tryouts in the fall? First and foremost, DO NOT WORRY. We only call them tryouts so people will understand what were talking about as long as Ive been on the squad, weve never cut anyone who was interested in joining. Tryouts are really more for you to try out the squad and see if you would enjoy being a cheerleader. Historically, about half the people on the squad did not cheer in high school certainly I didnt, and I was even captain of the squad my junior year.
