This work explains how the size of a carbon nanotube (CNT), urea, and temperature would influence the insertion of Tretinoin into CNT (10, 7) and CNT (8, 5) under 270 and 310 K via molecular dynamics simulation. 0.9 mmol mL-1 and 2 mol L-1 urea are studied that are less and more than the normal range of blood urea content respectively. It is found that the encapsulation of Tretinoin could be ascribed to the flow of the waters via hydrophilic interactions and diameter of the nanotube. By increasing

The cone is an important photoreceptor in the retina of the eye. Its function, primarily, is to see color while the rods, another photoreceptor located in the retina, is to see light. Overall, this paper will focus on the embryonic origin of the cone, the physiological functions of the cone, the pathology of the cone, as well as the growth factors of the cone. The development of the rod and cone begins in the first stages of life, in the embryo, requiring a series of events, which include three

Animal testing is commonly known as the experimentation of animals for research purposes. It is mostly used today for biomedical research and cosmetic testing. This research method has made a tremendous contribution to medical advancements and the protection of humans. Animals such as mice, dogs, cats, and even cows are used to perform experimental trials that help develop new medicine and better products. Although animal testing is seen as negative and inhumane to many, it is a beneficial way to

DNA methylation may manifest in adults as an increased response to stress.4 With methylation and the reduction in neurotransmitter pathways hormones are released in lower amounts leading to the elevated stress response.4 On studies done on adult rats, these effects were able to be reversed with histone deacetylase inhibitors allowing the DNA to remain in a transcriptionally active state.4 Adults exposed to binge drinking during fetal development also show an increase in substance dependence and personality

International Marketing The Cosmetics Industry Estee Lauder vs. Shiseido Cosmetics Introduction           The cosmetics business is a billion dollar industry. Every year, women are responsible for consuming millions of cosmetic products. The cosmetics industry is so large because of several factors. The media is a huge contributor to the intense pressure to look a certain way. The idea that “sex sells” is evident in gossip magazines, movies, advertisements, music, and more subtly-

experiences are controlled by GPCRs. There are hundreds of different GPCRs that control a range of functions within the body. An example of a GPCR is rhodopsin and protease-activated receptors (PARs). Rhodopsin, a 7 transmembrane (7TM), activates the retinol molecule that is covalently linked in the TM cavity 1. Rhodopsin does this by changing the configuration to activate the receptor; it changes from cis to trans 1. PAR is a family of 4 GPCRs that activate important signaling pathways 7. PARs activate

Chemical Kinetics is the branch of chemistry that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical

When looking at her health from a holistic perspective, BV meets and exceeds what is expected of a 73-year-old female. She is of a healthy weight range based on her BMI (18.8), never uses tobacco or alcohol, exercises regularly to prevent sarcopenia that affects many of her demographic, is happily married and living with her husband, and has no concerns about her nutrition and is satisfied with her current weight. BV recorded her food history for a 24-hour period and she was confident that this

worth living. Throughout my personal life, I faced with many difficult obstacles, and different challenges. I had go through five general anesthesia for five major surgeries in my life including tumor removal, skin graft surgery, tonsil removal, retinol hemorrhage after being hit by soccer ball, and extracting four wisdom teeth (which was nothing compared to other four). But of them all, learning a second language and overcoming my shyness were mentally the most difficult challenges that I ever faced
