Botulinum Toxin, David Moshayev
Botulinum Toxin, David Moshayev
The Science Journal of the Lander College of Arts and Sciences
Botulinum toxin is a neurotoxic protein produced by the bacterium Clostridium botulinum. Although botulinum toxin is the cause of the disease botulism and can be used in a terrorist attack, there are also many other uses for botulinum toxin. Botox, a derivative of botulinum toxin, is used for cosmetic purposes. Botulinum toxin is also used in medicines to control certain conditions marked by involuntary muscle contractions. The objective of this paper is to present a strong review of botulinum toxin so that one can see all the good and bad that is botulinum.
Biofilms In Medicine, Marshall Gelbman
Biofilms In Medicine, Marshall Gelbman
The Science Journal of the Lander College of Arts and Sciences
In 1862 Louis Pasteur introduced the “Germ Theory of Disease.” Subsequently the study of microbiology has flourished greatly and its medical significance has continuously grown. Many microbial organisms implicated in disease have been identified and studies. A general science of medical bacteriology has been determined and is widely taught. Such study has been largely based upon the activity of individual free-swimming (planktonic) cells and colonies that they form. However, microorganisms often form communities called biofilms which can have properties that very different from their planktonic predecessors. Biofilms are mucoid aggregates of microorganisms which tend to grow on surfaces exposed to …
Bisphosphonates And Osteonecrosis Of The Jaw, Chaya Leah Katz
Bisphosphonates And Osteonecrosis Of The Jaw, Chaya Leah Katz
The Science Journal of the Lander College of Arts and Sciences
Bisphosphonate-related Osteonecrosis of the Jaw (BRONJ) is a condition which, according to the American Association of Oral and Maxillofacial Surgeons (AAOMS), adversely affects between .8-12percent of the population, a small yet significant amount of adults. Osteonecrosis of the Jaw (ONJ) is characterized by the death of bone and suffering patients present with either a non-healing extraction socket or an exposed jawbone. In general, afflicted patients have been treated with a class of drugs known as the Bisphosphonates (BP). Bisphosphonates were originally developed in order to treat and manage many metastatic diseases of the bone and stabilize bone loss caused by …
The Effect Of Exercise On Alzheimer’S Disease, Benjamin Korman
The Effect Of Exercise On Alzheimer’S Disease, Benjamin Korman
The Science Journal of the Lander College of Arts and Sciences
Alzheimer’s disease (AD) is a progressive neurodegenerative disease, from which there is no recovery. It begins with impaired memory and judgement and progresses to the point where those affected can no longer care themselves. Although the cause of AD is unknown, two significant abnormalities occur in the brain of its victims: neurofibrillary tangles and amyloid plaques. It has been well established that exercise improves mood and general well-being, however this paper will focus on the effect of exercise on AD. It will show that exercise can improve physical functioning of an individual with AD, however more importantly it will focus …
Rhinoviruses: The Quest For A Cure, Michelle Gordon-Grunin
Rhinoviruses: The Quest For A Cure, Michelle Gordon-Grunin
The Science Journal of the Lander College of Arts and Sciences
Rhinoviruses, also known as Human Rhinovirus, abbreviated HRV, are one of the many causes of the common cold. In fact, around 50 percent of all cold are caused by rhinoviruses, with the other major candidates being coronaviruses, influenza A or B virus, and minor causative agents like parainfluenza virus, respiratory syncytial virus, adenovirus, and enterovirus (Makela and Puhakka, 1997). However, due to the complex molecular structure of rhinoviruses, a cure for the common cold caused by HRV is still in the making. Several new treatments have been discovered, impacting the virus as different stages of its life, hopefully to prevent …
Gestational Diabetes And Its Effects On The Fetus, Todd Pollack
Gestational Diabetes And Its Effects On The Fetus, Todd Pollack
The Science Journal of the Lander College of Arts and Sciences
Although the common effects of gestational diabetes on the fetus are known, the outcome of a diabetic gestation is ambiguous. There is concern for complications in the fetus at delivery due to enlarged size of the fetus, as well as concerns for birth defects, fetal distress, diabetes and obesity. Yet, although there is a correlation in the previous disorders and gestational diabetes, many of the mechanisms that cause these complications are unknown. By studying the pathology of gestational diabetes, researchers have learnt that the placenta controls fetal growth and provides a great deal of protection for the fetus. Therefore, many …
Botox And Its Effect On Wrinkles, Rochelle Eckstein
Botox And Its Effect On Wrinkles, Rochelle Eckstein
The Science Journal of the Lander College of Arts and Sciences
Clostridia Botulinum (C. Botulinum) is a bacterium that produces a unique exotoxin, botulinum toxin (BTX). BTX induces flaccid muscle paralysis by inhibiting the release of acetylcholine at the cholinergic nerve endings. Recently, Botox, developed from BTX, has become a popular solution to reduce the appearance of hyper-functional facial rhytids. Facial wrinkles are caused by repetitive muscle contraction, and a treatment that directly addresses this will be effective. Injections of Botox temporarily relax or paralyze these muscles. This paper will briefly discuss the bacterial basis of Botox and its development. It will explain how the mechanism of action of BTX can …
Insomnia: Its Causes, Its Consequences, And Its Cures, Shoshana Fried
Insomnia: Its Causes, Its Consequences, And Its Cures, Shoshana Fried
The Science Journal of the Lander College of Arts and Sciences
Insomnia is a complaint that affects almost all Americans at some point throughout their lives. However, only chronic insomnia is truly a disorder. This type of insomnia can be caused by various reasons, whether physiological, molecular, or psychological. This paper will elaborate on a number of possible causes for insomnia. Furthermore, this paper will present some of the many adverse effects that are caused by the sleep deprivation resulting from chronic insomnia. There are many possible treatments available to help against insomnia. This paper will explain 53 some of the behavioral methods. In addition, it will discuss the many different …
