Aureus is by analyzing the damaged tissue. Skin infections associated with S. Aureus usually result in Furuncles and Carbuncles, which are boils/lesions filled with abscess. Another skin infection caused by S. Aureus is Staphylococcal scalded skin syndrome (SSSS) which peels the skin’s stratum granulosum layer off causing desquamation. This is due to the toxins ability to hydrolyze desmoglein 1 which holds the keratinocytes together and the absence of desmoglein 3 in granulosum layer. The effects are red bright skin.
As it is the part of the eye that is responsible for central vision, sufferers therefore lose their ability to use their central vision. There are two types of AMD; Dry AMD and Wet AMD. Dry AMD develops when there is a build-up of waste products called drusen. A build-up of these waste products result in the damage of light cells of the macular leaving you with blurry central vision. Wet AMD however is a more severe case of AMD which develops due to abnormal blood vessels growing under the macular, believed to be caused because of a misguided attempt to clear the waste products.
The difference in diastatic malt products and non diastatic malt products is the difference in ezyme activity. Diastatic malt products have a considerable amount of enzymatic activity. The action of B amylase on undamaged/ungelatinised starch is extremely slow. A amylase attacks starch very quick. Both A and B amlyase both attack gelatinised starch rapidly.
Sputum contains a lot of bacteria, viruses, fungi and other pathogens. Respiratory infectious diseases, like influenza, tuberculosis, bronchitis, pneumonia, measles, pertussis, diphtheria and other pathogens, are spread through the sputum, very dangerous. Spitting there are many hazards, not only can cause health problems, in infectious disease multiple times, phlegm is a highly damaging route of transmission, inadvertently freely spit sputum are likely to have increased 10 people infected with the virus. First of all, spitting could lead to spread bacteria, into the air will harm to people. In our usual life, no spitting everywhere slogan, the reason is spitting is an extremely uncivilized unsanitary, spitting will make sputum bacteria spread easily, especially in public places, crowded place will make the spread of the virus.
Intruduction Salivary duct carcinoma (SDC) is an uncommon, extremely aggressive malignancy arising from the ductal epithelium of salivary glands. Salivary duct carcinoma is an inaccurate name for this entity because other salivary tumors are also of excretory or terminal ductal origin. It was originally reported by Oscar Kleinsasser in 1968 as Speichelgangcarcinome. SDC has been also termed cribiform salivary carcinoma of excretory ducts, intraductal carcinoma, and infiltrating salivary duct carcinoma. In the 1991 World Health Organization (WHO) classification SDC has been listed as a separate categorization because of its special clinical and pathologic characteristics.
The various colors in a tattoo are made from different mate-rials. For example, the red color comes from mercury, the green from chromium, the yellow from cadmium, and the blue from cobalt. Allergic reactions to red dyes occur more often than allergic rea-ctions to other colors. Allergies are an overreaction of the immune system. An allergic reaction can range from mild and annoying to sudden and life-threatening.
causes of stomach ulcer: stomach usually produces acid to help with the digestion of food and to destroy bacteria. This acid is corrosive, therefore some cells on the inside lining of the stomach and duodenum usually produce a natural mucus barrier which protects the lining of the stomach and duodenum. Generally there is always a balance between the acid amount that we make and the mucus protect barrier. Due to the alteration in this balance an ulcer may develop, allowing the acid to damage the lining of the duodenum or stomach . Infection with Helicobacter pylori: Infection b Helicobacter pylori (H. pylori) is the cases of stomach ulcer.
The results were recorded. 10. Steps 2–9 were repeated for heights 20cm, 60cm and 100cm. The straw was not the best apparatus to use as it would sometimes let off more than one drop which adjusted my results at a height of 60cm. I noticed that the higher the simulated blood was dropped on, the more ellipses would form.
A slight error in the indicator can shift the endpoint and consequently affects the volume of the obtained NaOH. Lastly, the final source of error of this experiment is misjudging the color of the indicator near the endpoint. The color change is very intricate that even a small amount of the standard solution can produce different shades of the color. With these uncertainties, a 23.3 % error was committed given that the theoretical molar concentration of acetic acid in the the vinegar sample is
However, not all industries recover the sodium hydroxide and other organic materials present in the black liquor. On the other hand, the disadvantages are the high initial costs, the strong smell of gases emitted by the process, low yield (40–50%) and the high cost of bleaching. It can be seen that in the Kraft process polluting reagents
During production when the oil is exposed to high heat and multiple solutes, that causes the different types of fats to go bad. A study was done on random bottles of Canola Oil and scientists found that .52% to 4.2% of the fatty acids were toxic trans fat. If trans fat is artificial, is can lead to heart disease which is the leading killer in the world. “Like all modern vegetable oils, Canola Oil goes through the process of refining, bleaching and degumming — all of which involve high temperatures or chemicals of questionable safety. And because Canola Oil is high in Omega-3 fatty acids, which easily become rancid and foul-smelling when subjected to oxygen and high temperatures, it must be deodorized.
However, high frequency light waves tend to kill many Drosophila Melanogaster (Hori et al.) Thus, the experiment was done using several colored lights: red light was tested to see if D. Melanogaster were insensitive to it, UV and green light were used to test the ends of the flies’ visible spectrum, and blue light was tested to investigate how short wavelengths affected the
Broad spectrum antibiotics tend to kill the bodies normal flora, which then allows bacterium’s like C. difficile to spread and grow rapidly in its vegetative state. Toxin A (enterotoxin) is then produced causing diarrhea, followed by toxin B (cytotoxin) which causes damage to the mucosal cells. Toxin A and B also induce the secretion of cytokines into host cells, which often cause an acute neutrophilic inflammatory infiltrate. Together, these toxins enable the interruption of tight junctions in the intestine and cause inflammation of the colon leading to an extensive amount of fluid secretion (diarrhea). A third toxin has recently been discovered in newer strains of this bacterium called the binary toxin.
Of course, the various sources of error have affected the results from this lab. Since the initial mass of eggs used was different for each group, the experimenters had to find the percent change in mass to keep the results constant. To conclude, when the eggs were placed in a corn syrup solution with more solute, their masses steadily decreased. The inside of the eggs have a lower solute concentration than the corn syrup solution outside the cell. Water within the eggs flow outwards through the membrane to the syrup solution, decreasing the solute concentration.
One study discovered that the huge quantity of starchy material in the roots of kudzu might possibly be gathered from an invaded area and handled. One kudzu field can theoretically yield sums of ethanol equivalent to maize harvested from a field of the same spread. The study demanded that not only would generating a market for the farming of kudzu decrease the degree of invasion, but would also fuel the agricultural economy of the Southeast. However, there are many obstacles to the application of this notion, beginning with the lack of technology for the harvesting of kudzu roots. Also, kudzu’s standing as a harmful weed as well as its recognizable unfavorable results on the ecosystem would prove to be meaningful obstructions to the constant use of kudzu as
