  • Stellate Cells And Pancreatic Cancer

    Stellate Cells (SC) are morphologically characterized by dendrites that radiate from the main cell body leading to a star-like shape and giving rise to the name Stellate i.e. star-like. They can be found in various parts of the body such as: kidneys, lungs, liver, breast, and pancreas; some of these ones have been less thoroughly characterized compared to others such as hepatic SC [1-5]. Although the dissimilar microenvironment of SC in different parts of the body condition them to react different, it have been shown that they have morphological and biochemical similarities. In their quiescent state, they store and transports vitamin A compounds (retinoid) in the form of droplets in their cytoplast. During an injury they undergo structural…

  • Insulin And Glucose Lab Report

    The Effect of Insulin and Glucagon Before and After Meals Lucy Foley Course number and section Experiment Date Lab Partners Introduction Blood glucose is the preferred energy source for our bodies. Blood glucose is the preferred fuel source for ATP production and neurons absolutely have to have glucose. Other cells can use alternative nutrients, such as fatty acids, glycerol, and amino acids. Without glucose, neurons cannot function meaning humans could seizure and/or die. There are two…

  • Portal Vein Injury Case Study

    The portal triad is typically approached from the right. A wide Kocher maneuver is performed to mobilize the duodenum and head of the pancreas. The ascending colon and hepatic flexure are mobilized with right medial visceral rotation. The duodenum and right colon are reflected to the left to expose the retro-pancreatic or supra-pancreatic portal vein. Occasionally, we enter the lesser sac and divide the neck of pancreas if exposure of more distal portal vein is required. Control of…

  • Analysis Of Your Inner Fish By Neil Shubin

    Neil Shubin’s documentary series “Your Inner Fish” explores the relationship between humans and all other living organisms. Shubin delves into human evolution to uncover similarities that connect humans with the world around them. The anatomist studies fossils, embryos, and various other parts to compare humans to fish, reptiles, and primates. Shubin challenges the common beliefs about evolution by recognizing the corresponding features between humans and seemingly unrelated organisms. The…

  • Human Cloning: The Characteristics Of Humans?

    the chromosomes. Clones come from a scientific process called the somatic cell nuclear transfer or SCNT. During this process, scientists remove the chromosomes from the egg cell and replace them with the nucleus of a somatic cell which contains two sets of chromosomes. Since the nucleus of the somatic cell comes from a human who already displays genetic variation from their mother and father, the clone will receive both of their sets of chromosomes from one cell, and not from both the egg and…

  • Animal Testing In Medicine

    studies that can contradict predetermined concepts. Therefore, researchers can be studying a peculiarity of some specie that can be resulted by many different factors. Trying to apply this new discovery in humans can be catastrophic as these new concepts cannot be applicable to human beings. For example in 1960’s, experimentation on animals showed that the tobacco did not cause lung cancer, although it caused some minor issues. This research was used for years as an argument to delay the…

  • Animal Cell Process Lab Report

    headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged polysaccharide which was…

  • Persuasive Essay On Gm Foods

    they are developed because there is some perceived advantage either for the producer or consumer of these foods. This is meant to translate into a product with a lower price, greater benefit in terms of durability or nutritional value. How can DNA be moved from one organism to another? • Find an organism with the desired trait • Isolate the gene sequence that codes for the desired trait • Insert the gene sequence into the genome of the plant cell • Allow the genetically altered cell to grow…

  • Should Human Cloning Be Banned

    Cloning is the production of one or more individual organisms that are genetically identical. The copied organism, which has the same genetic code as the original, is called a clone. In the last two decades, Cloning technology has been becoming mature, and been broadly applied on agriculture, human health, and many fields. Breeding by cloning is able to being directly reproduce an animal with a desirable set of genetic traits, the world 's most famous clone is Dolly the sheep that is the first…

  • Eukaryotes: A Genetic Analysis

    For all organisms, prokaryotes and eukaryotes, they all must regulate the specific genes that are expressed at any given time (Campbell 365). Each organism continuously turn on and off genes in response to external and internal environmental signals. The regulation of gene expression is especially important in multicellular organisms since it is essential for the different types of cell to have their own cell specialization (Campbell 365). In order for each cell to do it’s given role, they each…
