INTRODUCTION
The thyroid is Greek word for “shield shaped” from the shape of the nearby tracheal cartilage. The thyroid gland was named “glandulae thyroidaeae” by Wharton in 1656.[1] The thyroid gland is the source of two fundamentally different types of hormones, produced by thyroid follicles, idothyronine hormone thyroxine (T4) and 3, 5, 3’- triidotyronine (T3).

1.1 Regulation of thyroid hormones in human body
Thyroid hormones (T3 & T4) are essential for the growth and development and play an important role in energy metabolism. Serum concentration of thyroid hormones is precisely regulated by the Pituitary Hormones named as Thyrotropin (thyroid stimulating hormones TSH). The thyroid hormones thyroxine (T4) and triiodothyronine (T3) are formed by thyroglobulin, a large glycoprotein synthesized within the thyroid cell. Because of the unique tertiary structure of this glycoprotein, iodinated tyrosine residues present in thyro- globulin are able to bind together to form active thyroid hormones. Acting through nuclear receptors, these hormones plays a critical role in cell differentiation during development and helps in maintaining thermo genic and metabolic homeostasis in the adult. Autoimmune disorders of the thyroid

However, it remains unknown as to why no relationship between vitamin D status and serum TSH levels in middle-aged and elderly individuals was found in this study.[23] An another cross sectional study was performed to assess the relationship between vitamin D status and circulating TSH levels in middle-aged and elderly individuals with thyroid autoimmunity, while taking thyroid function into consideration of relationship between vitamin D insufficiency and thyroid autoimmunity, the presence of thyroid nodule(s) and thyroid
Suppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$
An electrocardiogram records the electrical activity on the surface of the heart. One method of acquiring an electrocardiogram is by the usage of a handheld single channel ECG machine. Figure 1 displays the results of my single electrocardiogram result. From this figure, one can calculate the heart rate by dividing the number of intervals over the time and multiplying by 60 in order to get the heart rate in beats per minute (BPM). Based on the electrocardiogram, there were 7 intervals in a time span of 6 seconds.
For example, a lump of fat on the back of the neck and weight gain in face and neck, but thin arms and legs are the two major characteristics of ACTH tumor. Last but not the least, the TSH tumor, which is thyroid-stimulating hormone tumor will cause weight loss, irregular heartbeat, and shakiness. In contrast, the non functional pituitary tumor has no real symptoms during initial stage, but it will cause symptoms by pressing the surrounding structures while the tumor is growing
Myxedema is the severest form of hypothyroidism and at this stage there is a swelling and thickening of the skin and if left untreated myxedema can lead to coma and death…this is because the thyroid gland doesn’t produce enough of the much needed thyroid harmones that the body needs to function
Top Vitamins for Bodybuilders: The Metabolic Spark Plugs: One of the most confusing issues for any athlete is supplementation. What to take, how much, when to take it, blah. Figuring out a supplementation regimen can be so frustrating at times that it becomes easy to lose sight of the forest for the trees, to forget the purpose of supplementation and to overlook exactly what makes successful bodybuilding. It's sometimes easy to forget that the cells in our bodies, particularly muscle cells, rely on certain biochemical reactions for proper metabolism, growth and maintenance.
3. I spent my young life struggling with this disease and my symptoms, my grandmother started having symptoms later in life around her 40’s. C. Possible environmental factors are also being studied. 1. For example, researchers have found that consuming too much iodine may inhibit thyroid hormone production in susceptible individuals.
Cortisol is a steroid hormone, the main glucocorticoid hormone made in the cortex of adrenal glands. It is responsible for regulating the metabolism of proteins, fats, and carbohydrates. Cortisol is responsible for maintenance of homeostasis. Cortisol is a stress hormone that releases under severe stress.
It is the property giving rise to the term hormone. Upon the discovery of melatonin in 1958, it was also in tallkottkörtlar of mammals were found there, and the long time it was thought that it was only in vertebrate tallkottkörtlar. This meant that the term hormone was close at hand. melatonin has many features that distinguish it from classical hormones : - It is also produced in many other organs like the eye, bone marrow, intestine and skin.
The investigation was carried out to identify the presence or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile. A reducing sugar solutions is add inside a test tube with 3 drops to then add 3 drops of benedicts and plane in a water bath.
Tn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed in aerobically grpwn E. coli, but not in anaerobically grpwn E. coli or in bacteroides.
• Write down the highlighted numbers. Do you observe a pattern? • Does the pattern grow? What is the reason for this? • Write down the last number (say 53).
The PTH helps control the calcium and phosphorus levels in the blood stream. So, without the secretions of the PTH, the human body will slowly start to shut down. Consequently, the parathyroid hormone is not ‘awake’ like the rest of the body is. Hypoparathyroidism can be triggered by “something that develops in childhood” or the adult life (Hypoparathyroidism). It can even be congenital, meaning, someone can be born with this disorder, or it can be inherited (Hypoparathyroidism).
Melatonin aids in sleep as well as ones biological clock. The thymus is located between the lungs behind the sternum and produces thymosin which help with immunity. The thyroid gland is located under the larynx in the neck and secretes calcitonin which is a hormone that decreases blood calcium levels which targets bones. The parathyroid gland is attached to the thyroid lobe (sits on the thyroid gland) and secretes PTH which is a hormone that does the opposite of calcitonin and increases blood calcium levels which target bone, kidneys, and the intestines. The adrenal glands are located on top of the kidney and consist of the adrenal cortex and the adrenal medulla.
3. I was recently diagnosed with hypothyroidism, and it has really affected my life in more ways than one. 4. When it isn’t functioning correctly, then it can cause thyroid disease. 5.
INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1
