Lymphocytic Choriomeningitis virus (LCMV) belongs to the Old World arenavirus family of enveloped viruses (Buchmeier et al., 2007). LCMV in particular has served as model organism from many significant studies in the field of immunology such as the Nobel Prize winning study of the Major Histocompatibility Complex (MHC) by Zinkernagel and Doherty (1975). LCMV’s natural reservoirs are the common household rodents (Traub, 1936). Household mice have shown to attain persistent asymptomatic LCMV…

Hypothyroidism Hypothyroidism is a condition in which your thyroid produce the improper levels of certain hormones that is needed to function properly. Women especially those older than 60 are more likely to have the disease. The disease rarely causes symptoms in the…

secrete hormones. Hormones are regulators of metabolism, growth, development, reproduction, and other activities. They also play roles in fluid and electrolyte balance, acid-base balance, and energy metabolism 1. One of the hormones is called the thyroid-stimulating hormone (TSH). The job of these hormones promote and maintain the growth and development; their target is the thyroid. Thyroid tissue is composed of tiny structural units called follicles, these are the sites where thyroid hormones…

Reflections 1. Hormones and the brain are powerful influences on human sexual functioning. Perhaps two of the most important portions of the brain in terms of sexual functioning are the hypothalamus and the pituitary gland, which make up the HPG axis. The HPG axis consists of the hypothalamus, pituitary gland, and the gonads – gonads being the testes in males and the ovaries in females. Together, the HPG axis regulates sex hormone production in a negative feedback loop. Three important hormones…

Thyroid hormone is an important hormone needed for brain maturation as it helps in the functioning of the brain throughout the life. Thyroid diseases have various clinical manifestations in adults like hypothyroidism causing lethargy, hyporeflexia and deprived motor coordination. Thyroid hormone deficiency can lead to irreversible brain damage depending on onset and duration time period. Subclinical hypothyroidism is usually related to memory damage, bipolar affective disorders, depression or…

is an essential for all cells in the body. This is because “it is involved in cell signaling, bone formation, and acid-base regulation”(cefic). The compound earlier stated, hydroxyapatite contains both calcium and phosphorus, which are critical for growth and development of the bone structure, as well as the maintenance throughout life. Phosphorus is a mineral acid found in many different foods naturally; however, the amount found in diet soda is unnatural. Elson M. Haas, a medical practitioner,…

Their are different hormones that help in the process of pregnancy , which are called pregnancy hormones the main hormones heard about when pregnancy hormones are mentioned are HCG ( Human Chorionic gonadotropin) ,Progesterone , prolactin and estrogen . HCG is the hormone responsible for keeping the structure of where the embryo will develop at early stages (called corpus luteum) from being shed and absorbed back into the body.HCG also stimulates the secretion of progesterone and estrogen by…

disorders which affects the glands function or structure. This paper will focus on hypothyroidism, its symptoms, treatments and effects on people. Hypothyroidism is a disorder that is common in endocrine and it results from the deficiency of thyroid hormone in the body. The most common cause of hypothyroidism in United States and areas of adequate iodine intake is autoimmune thyroid disease; whereas iodine deficiency in the rest of the world remains the major cause of the disorder. It occurs…

and growth and affects almost every organ of the body. The thyroid uses iodine in the food we eat to produce vital hormones like thyroxine or T4 and triiodothyronine, T3, both of which regulate the speed at which your cells metabolic processes function. The thyroid itself is regulated by the pituitary gland and hypothalamus and functions on a feedback system. Much like a thermostat, the body responds to the thyroid’s underproduction of hormones by causing the hypothalamus to produce a hormone…
