How Tissue Forms a Wound - 862 Words

When a tissue experiences the disruption of normal anatomic structure and function, it forms a wound. The process of restoring injured tissue to its normal structure and function by proliferation of neighboring living cells is called tissue regeneration (Sorg Reinke, 2012). However, when regenation cannot occurs, wound healing occurs by replacement with a connection tissue and formation of a scar (Porth, 2011). Wound healing process involves the restoration of the integrity of injured tissues. It consists of three continous or overlapping phases: inflammation, proliferation, and wound contraction and remodeling phases (Porth, 2011). Any interruption, prolongation, or changes in the course can lead to delayed wound healing. The inflammation phase starts at the time of injury with both cellular and vascular responses. this phase is critical because it prepares optimum environment for wound healing (Porth, 2011). During the vascular response, blood vessels constrict and blood clots for m to reduce blood loss as well as to fill the tissue gap. After that these vessels dilate and increase capillary permeability to allow plasma and blood components to leak into the wound. The accumulation of fluid causes the wound to appear swollen, red, and warm to touch (Sorg Reinke, 2012). Platelets and white blood cells release cytokines and growth factors to stimulate the collagen synthesis, activate the transformation of fibroblasts to myofibroblasts, start the angiogenesis, and supportShow MoreRelatedVenous Stasis Ulcer996 Words   |  4 Pagesthe skin resulting in tissue loss. It is estimated that venous stasis ulcers affect 500,000 to 600,000 people in the United States every year and it is by far the most common type of leg ulcer seen (Foot Pain Explained). A person may have an ulcer on one or both legs and each leg may have multiple ulcerations. These ulcers are found in the inner part of the lower leg and can be very painful.

Research work on acute wounds in an animal model shows that wounds heal in four phases. It is believed that chronic wounds must also go through the same basic phases. Some authors combine the first two phases.

Helicopter Parenting And Its Influence On Children s Life

Helicopter parenting has gained increasing awareness in popular media, academic literature, and the general population. For example, recently, several popular parenting books have raised awareness about parental over-involvement and how it may be associated with negative outcomes. The term â€Å"helicopter parent† was first used in a famous parenting book, Parents Teenagers by Dr. Haim Ginott in 1969, by teenagers who described their parents as â€Å"hovering over them†, like a helicopter. This term refers to a parenting style that is over-focused on children; being involved in a child’s life in ways that are over controlling and overprotective. Lester-Smith defines â€Å"helicopter† or overprotective parents as having a â€Å"heightened surveillance of their children’s lives† (September 14, 2015), so that children are never allowed to experience risk. This term is commonly applied to parents of college aged or high school students who belie ve that their children are not capable of doing tasks alone, so they might call a professor about their child’s poor grades or manage their child’s class schedule for them. Schiffrin et al. (2013) emphasize children’s need for autonomy and explain how this need increases over time â€Å"as they strive to become independent young adults† (p. 529). Therefore, parents are recommended to â€Å"adjust their level of involvement and control to their child’s developmental level† (Schiffrin et al., 2013, p. 529). However, many parents do not make this adjustment, and thisShow MoreRelatedHelicopter Parenting Is A Metaphor1014 Words   |  5 PagesHelicopter parenting is a metaphor that describes a style of parenting where parents act as helicopters hovering or shadowing over their children.

Yeast Pre-Lab Free Essays

Yeasts’ capability of undergoing ethanol fermentation, its ability to ferment other sugars and artificial sweeteners, and how lactase influences yeasts ability to use lactose as a food source Kristina Naydenova Father Michael Goetz Purpose Part A: To investigate whether yeast has the ability to ferment glucose to produce carbon dioxide gas and ethanol. Part B: To investigate whether yeast has the ability to ferment other sugars and artificial sweeteners and how lactase influences their ability to use lactose as a food source. Question Part A: Does yeast have the ability of undergoing ethanol fermentation? Part B: Does yeast have the ability to ferment other sugars and artificial sweeteners? Does lactase influence the ability of yeast to use lactose as a food source? Hypothesis Part A: If yeast produces carbon dioxide gas (the solution will turn cloudy due to carbon dioxide presence) and ethanol after fermenting glucose then it has the ability to undergo ethanol fermentation because ethanol fermentations reactants consist of glucose and the products consist of carbon dioxide gas and ethanol. We will write a custom essay sample on Yeast Pre-Lab or any similar topic only for you Order Now Part B: If yeast has the ability to ferment other sugars and artificial sweeteners then the products of the solution will consist of carbon dioxide gas and ethanol because the products of ethanol fermentation are carbon dioxide gas and ethanol. If lactase influences the ability of yeast to use lactose as a food source then the yeast will be able to use lactose to produce carbon dioxide gas and ethanol because the yeast will be capable of breaking down lactose into glucose and galactose.

The safety goggles and lab apron were put on. 2. Three flasks were labeled as â€Å"yeast and glucose,† â€Å"yeast,† and â€Å"glucose. † 3. 10 mL of glucose solution and 5 mL of yeast suspension were added to the â€Å"yeast and glucose† flask. 4. 10 mL of distilled water with 5 mL of yeast suspension to the â€Å"yeast and glucose† flask as a control. 5. 5 mL of distilled water with 10 mL of glucose solution were added to the â€Å"glucose† flask as a second control. 6. Cotton batting was placed in the mouth of the flasks to reduce air turbulence. . The cotton batting was removed carefully after 24 hours and the contents of each flask were smelled. A slight alcohol odour was detected. 8. Each flask was tested for the presence of carbon dioxide. The invisible gas mixture was slowly poured into a flask that contains 25 mL of limewater. The limewater flask was stoppered and the contents were swirled to mix the limewater with the gas. Observations were recorded. The flask was rinsed. 25 mL of fresh limewater was added before testing the next gas sample. . A ruler was used to place graduation marks at 0. 5 cm intervals along the sides of the test tubes. 10. Six beakers of warm water (35  °C) were prepared. The beakers were two-thirds full of warm water. 11. The six test tubes were labeled as â€Å"glucose,† â€Å"sucrose,† â€Å"lactose free milk,† â€Å"artificial sweetener (Splenda),†lactose free milk and lactase,† and â€Å"distilled water†. 12. 10 mL of the appropriate solutions to each test tube were added. 13. 5 mL of yeast suspension to each test tube were added. The test tubes were filled. 14. The test tubes were scaled with one-hole stoppers after the mixtures are placed in the test tubes. 15. One test tube was held. The holes in the stopper were covered, and the test tube was inverted and placed into a beaker of warm water. The process was repeated for all six solutions, using a different beaker for each solution. 16. The amount of gas produced after 1, 5 and 10 minutes was recorded using the graduation marks on the test tubes. Observations Table 1.
