baking soda and 1 pint (473 mL) of warm water. A bulb syringe, squeeze bottle, or neti pot can be used to spray or pour the solution into one nostril, and flows through the nasal cavity and into the other nostril. This action gets rid of mucus and open sinus passages, improving nasal symptoms, such as stuffiness and runny nose. According to a review of several studies, published in American Journal of Rhinology & Allergy, which evaluated the effectiveness of nasal irrigation in improving allergy…

soar high Description: The fertility rates in both men and women have reduced greatly and as a result majority of couples face permanent fertility failures. Research shows a good diet may help greatly What makes a meal right for your reproductive system? It is definitely not the first time that you may have seen the importance of a good diet being discussed. The reason may have been different, per say losing weight or getting a spotless skin, but the essence still remains the same irrespective…

classification is a radiologic classification system, developed in the 1960s, to describe fractures involving the growth plate in pediatric patients.1 It divides the fractures into five categories based on the extent of damage to the growth plate based on the mnemonic SALTER; type I: Slip or Separation of the growth plate, type II: Above the growth plate, type III: Lower than the growth plate, type IV: Through the growth plate, and type V: Raised epiphysis. Children have open growth plates until…

Rhabdomyosarcoma, also know as RMS, is a type of sarcoma in which cancer cells form a muscle tissue. There are three main types this disease has, Embryonal, Alveolar, and Anaplastic. There is also stage I, stage II, stage III, and stage IV. There are treatments for RMS but it's all depending on the area, type, and stage of the cancer, survival rates will also fall under that. As far as symptoms, it can be very difficult to find early stages, since RMS mostly diagnosed in children younger than 5…

Discovery of Uranus William Herschel had a few motivations that led to his discovery of Uranus. However, “[he] spent most nights observing nebulae, looking for double stars, and searching for signs of life on other worlds.” (Ruskin 282) He basically discovered Uranus by accident supposing at first that it was a comet. After sharing his find with other astronomers, they questioned whether it was a comet at all. One astronomer named Nevil Maskelyne “suggested that [it] might be a planet” but it…

developing a new system for gene delivery into cells that could penetrate the barriers of the immune system and physical barriers. The basis for a new therapy were the gold nanoparticles surrounded by a shell of a plurality of spherical molecules of RNA. According bioengineers, spherical particle structure allows it to pass unobstructed through the immune barrier on the surface of the skin and pass through the pores in the cell walls. When nanosphere penetrates the cell, it opens and the cell…

their practical implementation in real time systems is still an open field of research. In this paper we present a practical implementation scheme of PID control strategy on a system which has been mechanically modelled to simulate the basic movements of an underwater vehicle. The movements which have been simulated in this study are the pitching and the yawing or the heading movements. The mechanics of an underwater vehicle have been related with the system under study and has been presented…

while food is being digested into the body. Among the many things that the digestive system has to offer it also has it’s not so good perks like symptoms & disorders. I have chosen to research about how an infected appendix can affect anybody without a single warning. I will also discuss how it affected a very well-known solo artist and his ordeal behind his Appendicitis. The Digestive System is a long complex system that is made up of many separate functional organs that make up the body…

Systemic Lupus Erythematosus (SLE) Systemic Lupus Erythematosus is an autoimmune disease, where the body’s immune system mistakenly attacks healthy tissue. To fight diseases our bodies produce antibodies, but in an SLE patient’s case, their body will produce what’s called ‘autoantibodies’. This means their immune system cannot tell the difference between foreign invaders and healthy cells. These autoantibodies cause the symptoms of the disease. Lupus can affect the skin, joints,…

“Humans are the only natural hosts of measles virus” (cdc.gov). “The virus typically first comes in contact with host lung tissue, where it infects immune cells called macrophages and dendritic, cells which serve as an early defense and warning system” (sciencemag.org). Then after that these infected cells will migrate to the lymph nodes, transferring the virus to B and T cells. “As soon as it enters the body the virus multiplies in the back of the throat,…
