1.2.3 Gelatin Gelatin is a translucent, colorless, brittle (when dry), flavorless food derived from collagenobtained from various animal raw materials. It is commonly used as a gellingagent in food, pharmaceutical drugs, photography, and cosmetic manufacturing. Substances containing gelatin or functioning in a similar way are called "gelatinous". Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which…

Nitric oxide can be administered by a few different ways. When a patient is on a ventilator, nitric oxide is nebulized on the inspiratory cycle. Nitric oxide can also be given by a facemask or even a nasal cannula. The normal ranges for nitric oxide is 1 – 80 parts per million. High levels of nitric oxide can be very harmful and may even cause death, pulmonary edema or methemoglobinemia. A high concentration would be considered to be between 5,000 and 20,000 ppm. The length of time that…

Gathered from the data, it seems that commercial products are more effective than natural remedies; natural remedies made little if no contribution in inhibiting bacteria. This result however, does not signify that natural remedies are inadequate at inhibiting bacteria. It reflects that natural remedies are ineffective in inhibiting gram-positive bacteria. First natural product: Saliva for instance, is one of the body’s many defence mechanisms. Its main function is to prevent adhesion of…

The Upper Respiratory Tract The human respiratory system involves complex organization of structural and defense mechanisms for the inhalation and exhalation of gases. The primary function of the respiratory system is to breathe air, provide oxygen to the bloodstream, and expel carbon dioxide. The respiratory system also provides transport of respiratory gases, internal respiration, pulmonary ventilation, and external respiration. There are two zones of the respiratory system, the conducting…

Jen Dowling Professor Sabalewski CHEM 102 Honors Recycling In our world it is crucial that people recycle as often as possible to help save the planet. The most common material to be recycled is paper. There is more paper recycled every year than aluminum, plastic and glass combined. In 2011, over 65% of paper in the United States was recycled. Paper can be recycled five to seven times before the fibers are too small to create any new paper. When paper reaches a recycling center it is…

Sickle Cell Anemia Sickle cell anemia is an inherited disorder that allows for some treatment, however the average life expectancy of a patient will Sickle cell anemia is only 30 years. An inherited gene causes the hemoglobin in the blood to become misshaped. Hemoglobin is the part of the red blood cells (RBC) that carries the oxygen to all of the body’s tissues and organs. This leads to inadequate amounts of oxygen to be carried on the hemoglobin, thus resulting in insufficient oxygenation for…

(equivalent to 4% w/v available chlorine at the time of manufacture), and XXX g L-1sodium hydroxide (NaOH). Chemicals used for feather treatment were 15% sodium hypochlorite, ethanol absolute, methanol, ether, 30% hydrogen peroxide, Cationic Surfactant, and n-hexane supplied by xxx. Sodium hydroxide pellets, and sodium dodecyl sulphate powder were supplied by xxx. Equipment Equipment used in this study is presented in three parts, equipment used for lab scale experiments, large…

Abstract: We describe the successful synthesis of Polypyrrole-Gold nanocomposites (PPy-Au NCs) by the chemical oxidative polymerization of pyrrole with ferric chloride as an oxidizing agent, in the presence of a colloidal suspension of gold nanoparticles. Gold nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier…

is another complications while having breathing problems from being born premature. A baby developes RDS when the lungs do not produce sufficient amounts of surfactant. Surfactant is a substance that keeps the tiny air sacs in the lungs open. RDS is common in premature babies because the babies lungs usually do not begin producing surfactant until about 30 weeks of the pregnancy. These complications are caused by premature birth. Another short term complication is heart problems. “ The earlier…

cause feeding problems, diarrhea, or swollen tummy. Patent ductus arterioles. A heart problem that usually happens between the two major blood vessels near the heart. Respiratory disease syndrome. Babies who have RDS lacks with a protein called surfactant that is responisble for keeping the small air sacs In the lungs from collapsing. Retinopathy of prematurity. This can lead to vision loss because there is an abnormal growth of blood vessels in the eyes. What are the chance of survival for…
