Dentistry: Are Stem Cells The Future?, Tova Zemel
The Science Journal of the Lander College of Arts and Sciences
Stem cell research is currently advancing in every area of medicine. New information about regenerating stem cells is being uncovered on a daily basis. An area of stem cells that has not been focused on until recently is the use of dental stem cells. The objective of this paper is to elucidate the most current research about dental stem cells. Much of what is discussed in this paper has not been implemented yet, and is still in clinical trials. Dental stem cells are important because they could be an alternative way of treating caries, performing root canals, and other traumas …
Possible Causes Of Preeclampsia And Potential Treatments, Helene Weinreb
Possible Causes Of Preeclampsia And Potential Treatments, Helene Weinreb
The Science Journal of the Lander College of Arts and Sciences
Preeclampsia is a common complication of pregnancy characterized by hypertension and proteinuria. Its symptoms are well-defined, but the pathophysiology is not fully understood. This paper analyzes several of the most credible causes of this syndrome and attempts to relate these to the known risk factors. Current preeclampsia treatments are examined, and special focus is given to novel experimental treatments which offer hope of ending preeclampsia and eclampsia.
Pathogenic Mechanisms Of Takotsubo Cardiomyopathy Or Broken Heart Syndrome, Devorah Leah Borisute
Pathogenic Mechanisms Of Takotsubo Cardiomyopathy Or Broken Heart Syndrome, Devorah Leah Borisute
The Science Journal of the Lander College of Arts and Sciences
Takotsubo Cardiomyopathy (TTC) is a temporary heart-wall motion abnormality with the clinical presentation of a myocardial infarction. Found predominantly in postmenopausal women, TTC most often appears with apical ballooning and mid-ventricle hypokinesis. Often induced by an emotional or physical stress, TTC is reversible and excluded as a diagnosis in patients with acute plaque rupture and obstructive coronary disease. The transient nature and positive prognosis of this cardiomyopathy leaves a dilemma as to what precipitates it. This paper explores the theories of the pathogenesis of TTC including coronary artery spasm, microvascular dysfunction, and catecholamine excess. A thorough analysis of the pathogenesis …

The Association Between Type Of Fat And The Risk Of Developing Cardiovascular Diseases, Dovid Leib Glassner
The Science Journal of the Lander College of Arts and Sciences
Objective: To determine the significance of various types of dietary fat in the progression of atherosclerosis leading to heart disease. Methods: Study inclusion criteria constituted relevance to the discussion topic and peer reviewed literature. Age of the published material was taken into account as well, with greater preference being given to more recent research as the topic of nutrition and its relation to chronic disease remains an emerging science. Results: This research review found an overall significant relationship between the type (monounsaturated, polyunsaturated, saturated and trans-fat) of dietary fat intake and the incidence of cardiovascular disease. While earlier research identified …
Artificial Sweeteners And Weight Gain: Fighting Or Feeding The Obesity Epidemic?, Shanna Frisch
Artificial Sweeteners And Weight Gain: Fighting Or Feeding The Obesity Epidemic?, Shanna Frisch
The Science Journal of the Lander College of Arts and Sciences
Our world has developed an obsession with weight control and, as a result, has begun replacing high calorie foods with low-fat and non-caloric substitutes. Artificial sweeteners are a widely used solution to this growing problem. Though the intention when using artificial sweeteners is to lose weight, studies have shown that the opposite sometimes occurs. Researchers attempt to explain this surprising phenomenon with multiple hypotheses. Lack of appetite suppression and reward response may cause individuals to search for more food and to consume more calories. Artificial sweeteners can also have negative affects on biological mechanisms such as resting metabolic rate, as …
Human Animal Chimeras For Therapeutic Protocols, Bracha Sklar
Human Animal Chimeras For Therapeutic Protocols, Bracha Sklar
The Science Journal of the Lander College of Arts and Sciences
Research on humans is limited, therefore human animal chimeras have been used to study human systems. A Human animal chimera is an animal containing animal and human cell lines. The primary goal of human animal chimera research is to establish an animal with human cellular characters, which can and should more realistically be able to imitate as closely as possible the in vivo situations in humans. This research is very important, because it allows scientists to study human systems in vivo using a humanized animal model. However ethical issues arise when experimenting with humans and animals being mixed together. Using …
The Neurological Underpinnings Of Hypnosis And Its Clinical Applications, Raizy Leizerowski
The Neurological Underpinnings Of Hypnosis And Its Clinical Applications, Raizy Leizerowski
The Science Journal of the Lander College of Arts and Sciences
The brain is so complex that it is almost impossible to select one variable as the reason for a specific observation. This paper will discuss the neurological basis of hypnosis, and how hypnosis has made unique contributions to the refinement and development of cognitive neuroscience. In addition, hypnosis has been proven to cure many psychological and neurologically based diseases. Due to in-depth study of the neurological underpinnings of hypnosis, much advancement has been made in elucidating the relationship between the complex neural circuitry of the brain, its direct correlation to consciousness, and both the efferent and afferent neurological systems. New …
Vigorous Exercise Effect On Cardiovascular Health, Aryeh Mahana
Vigorous Exercise Effect On Cardiovascular Health, Aryeh Mahana
The Science Journal of the Lander College of Arts and Sciences
Many studies examine the effects of vigorous cardiovascular exercise on the heart. Intense exercise causes frequent muscle contractions in the heart and specific biomarkers that usually signify a myocardial infarction are released into the bloodstream. However, studies indicate that there might not be a correlation between the release of biomarkers and cardiac function. Another study shows that long term vigorous exercise negatively affects the heart by dramatically increasing the mass and volume of the right and left ventricles, thereby resulting in hypertrophy. The cardiac hypertrophy is still evident even after the subjects have stopped exercising. Cardiac hypertrophy results in myocardial …
Should Sports Drinks Be Given To Children And Adolescents Engaged In Athletics As An Effective Source Of Hydration?, Zeev W. Rubinson
Should Sports Drinks Be Given To Children And Adolescents Engaged In Athletics As An Effective Source Of Hydration?, Zeev W. Rubinson
The Science Journal of the Lander College of Arts and Sciences
Dehydration in children and adolescents is a major concern for caretakers. Often children are not drinking enough, particularly while participating in physical activity. Utilizing data drawn from pediatricians, nutritionists, and bio-scientists, this paper will examine whether sports drinks are a good source of fluids for the exercising child. The results of the research indicate that the advantages generally associated with sports drinks, to achieve higher body water absorption levels, prevent electrolyte deficits, and maintain proper electrolyte/water concentrations, are reserved for unique circumstances. Sports drink intake should be encouraged only when the child is participating in prolonged physical activity, in intense …
Eating Disorders: The Hidden Hormonal Effect On Fertility, Esther Tessler-Karfunkel
Eating Disorders: The Hidden Hormonal Effect On Fertility, Esther Tessler-Karfunkel
The Science Journal of the Lander College of Arts and Sciences
Women who have a history of eating disorders, specifically anorexia nervosa, are more prone to suffer from infertility. There are several hormones which are the driving force in this system and are therefore responsible for this. Fortunately, there are treatments which can help women with a history of eating disorders to reproduce. Using information found on Pubmed and Touro College’s database, this paper will discuss why the body cannot reproduce when it is lacking proper nutrition, as well as the various dynamics in the human reproductive system which are compromised when the body is not properly nourished.

Cancer Immunotherapy Treatments, Shifra Sadowsky
The Science Journal of the Lander College of Arts and Sciences
Cancer is the second leading cause of death in American, with over half a million deaths from cancer reported in 2009. Cancer chemotherapy treatments were developed in the nineteen hundreds and remain the backbone of current treatments; however, they have some limitations. New immunotherapy cancer treatments, where biologic agents are given to patients to influence the body’s natural immune response, are being researched. Among these immunotherapy treatments are co-inhibition blockade of T cells, and combination blockade treatments together with chemotherapy treatment. This review will discuss T cell activation and the role of T cell coinhibitors such as CTLA-4 and PD-1 …
