The Microbiology degree includes a broad background and education in the sciences, including chemistry, biology, physics, and mathematics as well as specific, focused training in the field of microbiology. Majors complete 42 credits in microbiology departmental courses. Much of the advanced coursework displays an integrated approach to the study of prokaryotic and eukaryotic organisms with a major emphasis in microbial pathogenesis. This includes an analysis of virulence factors, bacterial toxins, lipopolysaccharides, and outer membrane proteins, interactions of pathogens and their products with eukaryotic host cells (cellular microbiology), antigenic variation, contemporary vaccine strategies, bacterial gene regulation (osmoregulation, quorum sensing), bacterial export and secretion, and genetic regulation of bacterial virulence expression.

Prerequisites (State Mandated Common Prerequisites) for Students Transferring from a Florida College System Institution: Students should complete the following prerequisites at the lower level prior to entering the university.

Physiology

What is Human Physiology?

Field Overview

Human physiology is the science of the functioning of human organs and the cells that compose them. Human physiology studies the mechanical, physical, and biochemical functions that determine the health of an individual. While anatomy studies form, physiology is the study of function.

Human physiology is broken into four levels of increasing physiological complexity. The most basic level is the molecular level, which includes all chemical substances that are necessary for cells to function. At the tissue level, study expands to examine function of the basic types of tissue, including epithelial, muscle, nervous, and connective tissues. The third level of study is the organ level. An organ consists of two or more tissues that perform a certain function. Typical organs studied include heart, liver, lungs, and stomach. The fourth level of study is the system level, which studies the functions of the major systems of the human body:

Many occupations incorporate human physiology and are listed by the Bureau of Labor Statistics. They include fitness trainers who work in spas or gyms where they organize and direct health and fitness programs. Biological scientists study living organisms and their relationship to the environment. Physician assistants practice medicine under supervision of physicians and surgeons and must understand human physiology to treat patients. Recreational therapists provide treatment and recreation for individuals with disabilities. Human physiology is also essential for those involved in cancer study and research, breathing-related illnesses, and liver and heart disease.

State-of-the-art education and training in psychiatry, psychology and related fields. Ground-breaking research on the brain, human behavior and mental illness. Excellence in providing compassionate care to all patients. These are the hallmarks of the Department of Psychiatry and Human Behavior at the University of Mississippi Medical Center.

Academic programs in the Department of Psychiatry and Human Behavior focus on educating the next generation of professionals, giving them training in psychiatry and the behavioral sciences through curricula, residency programs and mentoring. Programs in psychiatry, psychology, neuroscience, and research monitoring and fellowships in child and adolescent psychiatry and sleep medicine attract students from across the globe.

Understanding the science of mental illness, addiction, post-traumatic stress disorder and other conditions requires an integrative study of biology, behavior, affect and cognition. Translational psychiatric research at UMMC is supported by more than 13 National Institutes of Health grants in addition to funding from the Department of Defense and the Substance Abuse and Mental Health Services Administration.

Knowledge becomes care at the Department of Psychiatry and Human Behavior's clinical programs. Highly trained psychiatrists, psychologists, social workers, licensed therapists and nurse practitioners provide a wide range of services for children, adolescents and adults in inpatient and outpatient settings.

Genetics

Center for Cardiovascular Genetics | University Hospitals …

The Center for Cardiovascular Genetics at University Hospitals Harrington Heart & Vascular Institute specializes in evaluation, treatment, diagnosis and genetic counseling for individuals of all ages and their family members. The goal of the Center for Cardiovascular Genetics is to identify and treat patients with inherited cardiac conditions, those at risk of developing an inherited cardiac condition, and those who are at risk for sudden cardiac death.

Although many cardiac conditions result from diet, smoking, lack of exercise, high cholesterol, or other medical conditions such as diabetes, some cardiac conditions are the result of a genetic abnormality. These genetic abnormalities can result in problems with the hearts muscle function (cardiomyopathy) or problems with the hearts electrical system, which may put patients at risk for sudden cardiac death.

A genetic abnormality can be inherited and passed down through families. Family members with the same genetic abnormality may present with a variable degree of symptoms. Some patients may have no symptoms and others will have significant symptoms.

Inherited cardiac conditions which may put patients at risk for sudden cardiac death or arrest (SCD/A) include:

Comprising physicians specializing in cardiomyopathy, congestive heart failure, cardiac electrophysiology, medical genetics and a certified genetic counselor, the Center for Cardiovascular Genetics is designed to identify patients with inherited conditions or genetically determined cardiac disease. Diagnosis of an inherited condition can be made using a combination of cardiac and genetic testing.

Consultation with a medical geneticist and certified genetic counselor may be recommended to determine if genetic testing will aid in the diagnosis, direct treatment strategy, and identify other at-risk or affected family members.

As an outpatient clinic, patients may meet and be evaluated by an electrophysiologist (a doctor specializing in heart rhythm disorders), a cardiologist specializing in cardiomyopathy, and a registered nurse.

Cardiac evaluation will include a thorough history and physical examination. Sometimes additional testing may be recommended in order to establish the patients diagnosis or risk. This may include one or more of the following:

Once a diagnosis is made, the patient will meet with the medical geneticist and the genetic counselor to discuss whether genetic testing would benefit them or other members of their family. Genetic testing is done by providing a sample of blood that will be sent to a laboratory where the genetic material will be examined. The genetic analysis will look for abnormal changes in genetic information that are responsible for the inherited cardiac disease.

Once the genetic testing is complete, the patient will return to the Center for Cardiovascular Genetics where the genetic results will be discussed with the geneticist and the genetic counselor. They will explain what the findings mean for the patient and his or her family members. They can also help patients discuss this information with other family members.
