Effects of Dyshidrotic Eczema Research Mikayla K. Stabler IB Anatomy & Physiology 28, October, 2015 Abstract This research paper explores three published articles by three different authors about the skin disease dyshidrotic eczema. These articles vary in the description of the skin disease. They all suggest that dyshidrotic eczema come from allergies or stress. Dyshidrotic Eczema is a type of skin disease that has caused blisters to develop on mostly the hands and feet of most patients

Aspergillus is common mold that can live indoors and outdoors. There are about two hundred species of mold, but only sixteen of them are dangerous to one’s health. Everyone in our country has been exposed to one or more types of Aspergillus during their lives. Most people can live with it and never really get sick. The exception to that are people who have weakened immune systems that cannot fight off the infection without help. For immune compromised people breathing in Aspergillus is deadly

Treatment Fungal infections caused by Aspergillosis (Aspergillus Fumigatus) have a high mortality rate because they are not only difficult to treat, but there are a limited number of drugs that serve as an effective treatment. The three major drugs used to treat Aspergillus fumigatus are amphotericin B, voriconazole, and isavuconazole. Physicians have recommended amphotericin B for patients suffering from Aspergillosis for decades, but they have yet to fully understand the mechanism behind this

temperature on bacterial amylase, Bacillus licheniformis, and fungal amylase, Aspergillus oryzae, and ultimately find their optimum temperature at which it breaks down starch to maltose. The Bacillus licheniformis and Aspergillus oryzae were exposed to different temperatures to represent different environments, in order to find the true optimal temperature for each. The temperatures the Bacillus licheniformis and Aspergillus oryzae were placed in are: 0℃, 25℃, 55℃, and 85℃. For a duration of ten minutes

AFLATOXINS: Aflatoxins are naturally occurring mycotoxins that are produced by Aspergillus flavus and Aspergillus parasiticus species of fungi.The name, aflatoxin, was created around 1960 after the discovery that the source of "Turkey 'X' disease" was Aspergillus flavus toxins. Aflatoxins are toxic and among the most carcinogenic substances. After entering the body aflatoxins may be metabolized by the liver to a reactive epoxide intermediate or hydrolated to become the less harmful aflatoxin M1

their antibiotic resistant profiles. A total of 44 kerato-conjunctivitis samples were collected, out of which, 31/44 (73%) were fungal isolates . The prevalence of fungal isolates was as follows- 7 Aspergillus fumigatus (22.5%), 3 Aspergillus flavus (9.67%), 4 Aspergillus nidulans (12.9%), 7 Aspergillus niger (22.5%), 10 Fusarium sps. (32.25%). A total of 39/44 (86.36%) bacterial isolates were obtained in this study. The prevalence of bacterial

and at low temperatures, the frequency and rate of reaction decreases causing for a halt in product formation (Pitzer et.al., 2012). Thus, showing that enzymes need to be in their optimal environments to work properly. Bacillus lincheniformis and Aspergillus oryzae are both organisms that live that in medium temperature environments. Bacillus Linchenilormis has an optimal temperature of 45°C to 50°C, whereas

Cellulases and xylanases from Trichoderma viride and T. reesei help in the tanning of leather finishing fabrics and making stonewashed jeans. An enzyme supplement BeanoTM used in cases of digestive discomfort is derived from α-galactosidase from Aspergillus terreus. Peroxidases and xylanases from Trametes and Phanerochaete are used in the bioleaching of cellulose in hardwood. Xylanases also break down the polysaccharide xylan. Lacase which is produced by many fungi is used in the making of paper. Enzymes

structure in this structure you can find haploid ascospores. Important to humans - They are very important for us as we used them in baking, brewing, and wine fermentation, plus truffles and morels, which are held as gourmet delicacies. Also, aspergillus oryzae is used in the fermentation of rice.Also, they are used for threat to AIDS patients who have a compromised immune system. Why they need to be studied - They are studied as they are used in baking , brewing and wine fermentation and to study

The risk of infections increases in people that are HIV positive, but marijuana doesn't affect the development of AIDS or decrease white cell counts. The immune system can also be weakened by Aspergillus, which is a mold that can cause lung problems. Aspergillus grows on marijuana so that when it is smoked the fungus is then exposed to the lungs ("Marijuana and Lung Health"). Fungus within the lungs decreases the effectiveness of lungs significantly. Smoking cannabis is harmful

Gilliam (1997), reported that yeasts and molds are found naturally in the honey of honeybee. It is believed that microorganisms associated with bees are non-pathogenic. However, not all bees contain molds and the presence of molds are varied from colony to colony. Molds could contribute to the antimicrobial compound secretion to prevent stored food spoilage. They are also contributing to organic acids and other metabolites production (Gilliam et al., 1989; Gilliam, 1997). A terrific relationship

Matthew Morris Marijuana contains at least fifty percent more cancer-causing substances than tobacco. Studies show that one joint full of marijuana can do the equivalent amount of damage as five cigarettes. Smoking cannabis can cause long can suffer long-term lung damage. It can result in permanent damage to the respiratory system and bronchitis. Marijuana has been proven to damage the layers of cells that line the inside of the lungs, which is why smoking marijuana causes coughing and wheezing

observed in many field studies. Thus, during the present investigation the facts that the inoculation of PSF has a positive effect on the growth and productivity of plants, has led us to in vitro and pot experiment studies to observe the ability of Aspergillus niger K7 in the growth, yield and nutrient absorption of plants against the soil

inflammation of the bronchial tubes which carry air to your lungs. Chronic bronchitis can lead to coughing and difficulty breathing. Another affect it has is on the immune-system which can lead to other diseases such as Aspergillus having an easier access to your body. Aspergillus is a fungal infection in the lungs. If that’s in an adult’s body, imagine what it can do in a teen’s body. But there is a special effect that marijuana

Figure 1: Chemical structure of Aflatoxin (B1, B2, M1, M2, G1 and G2) Ochratoxins They occur in nature as Ochratoxin A, B, and C. Ochratoxin A (OTA) is a mycotoxin produced by several fungi (Penicillium, Fusarium and Aspergillus species), and occurs naturally in a variety of plant products such as cereals, coffee, beans, pulses and dried fruit all over the world (Duarte et al., 2010). It has been detected also in products such as wine, beer and grape juice (Sage et al., 2002). It occurs in kidney

Marijuana and Hashish commonly called “pot” or “grass”, marijuana is produced from the leave of Cannabis sativa. Hashish is a concentrated form of cannabis made from unadulterated resin from the female plant. The main active ingredient in both marijuana and hashish is tetrahydrocannabinol (THC), a mild hallucinogen. Marijuana is a drug commonly used by teenagers. Marijuana is not physically addicting, but its long-term effects have been the subject of much debate. However, the use of marijuana for

How Temperature Affects Bacterial and Fungal Amylase Activity Vanessa Romero Vanessa Romero 0058506 Group 1: Vanessa Romero, Kayla Montero, Aixa Andion-Arias, Sophia Tavarez Biology 1010L Section U36 Abstract: Several experiments were conducted on bacterial and fungal amylase, examining the rate at which both break down starch at various temperatures. Enzymes act as catalysts to accelerate reactions. Amylase is a type of enzyme that catalyses the breakdown of starch into sugars

extraction and clarification of fruit juices, removal of pectin from pectic waste waters and tea leaves maceration and other biotechnological applications (Kashyap et al., 2000; Rajendran, 2011 ). These enzymes are commonly produced by Erwinia sp., Aspergillus niger, and by plants such as peaches, carrots, apples and citrus (Alonso et al., 2003). This group of enzymes consists of pectinesterase (PE (E.C 3.1.1.11)), polygalacturonase (PG (E.C 3.2.1.15)) and pectin lyase (PL (E.C 4.2.2.10)) (Singh & Mandal

advantages of using catalase is that shortens the process duration, improves productivity, decrease the amount of water required and saves energy (Zhang, Du and Chen, 2010). 5. Catalase is used in the papermaking industry: The catalase is made up of Aspergillus niger, the catalase works by removing the excess hydrogen peroxide after the bleaching process. It works by breaking down hydrogen peroxide and producing water and oxygen. The use of catalase shortens the process time, saves energy and reduces
