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).
Fig 1.1:- Conversion of T4 to T3 and Reverse 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.

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

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.

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.

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 $N(-1.0558) = 0.1456.$

Each conducts a different function. The adrenal cortex is the outer portion of the adrenal gland and produces steroids such as aldosterone which reabsorbs sodium and releases potassium. The adrenal cortex is vital to sustain life. The adrenal medulla is the inner part of the adrenal gland and produces adrenaline hormones such as norepinephrine and epinephrine that are used in sudden stress

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

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.

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.

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.

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).

Unlike the synoptic gospels on Matthew, Mark, and Luke, the Book of John provides an intentionally different view of Jesus' life and ministry. According to John 20:30-31, John wrote his gospel to provide evidence to believers' that Jesus was truly the Messiah. As a result, 93% of the content contained in John's gospel differs from the synoptic gospels (Cole, 2013). Additionally, since the Book of John was written after the each of the synoptic gospels, it is reasonable to assume John was aware of the other gospels and intentionally choose to highlight different aspects of Jesus' life and ministry as evidence that Jesus was the Son of God. Therefore, I am aligned with the scholars that ascert John wrote his gospel to bolster the faith of

By analyzing the effects of the Estrogen receptor alpha on beta cells, our lab will be achieving the goal of my lab. We are doing this by observing if Estrogen receptor alpha causes insulin resistance or if it guards beta cells to keep there functionality when apoptosis occurs when there is Endoplasmic reticulum stress. While this project fits directly in line with our objectives at my lab, it also fits into the bigger picture in the endocrinology field. While endocrinology is the study of the hormones and endocrine gland, the main disease that is associated with endocrinologists is diabetes. Diabetes is connected with insulin resistance or beta cell deficiency.
