The Thyroid Gland01:23

The Thyroid Gland

7.8K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

5.8K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

8.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Scanning Electron Microscopy01:07

Scanning Electron Microscopy

5.6K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Voltammetric Techniques: Linear-Scan (E vs Time)01:12

Voltammetric Techniques: Linear-Scan (E vs Time)

1.3K
Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...

Area of Science:

  • Medical imaging
  • Ultrasound technology
  • Signal processing

Background:

  • Ultrasound imaging is crucial for thyroid lesion characterization.
  • Current methods may have limitations in differentiating lesion types.
  • Novel analytical frameworks are needed to improve diagnostic accuracy.

Purpose of the Study:

  • To evaluate the efficacy of H-scan analysis for classifying thyroid lesions.
  • To investigate the H-scan outputs for normal thyroid tissue, benign, and cancerous lesions.
  • To establish reference values using phantom studies for H-scan analysis.

Main Methods:

  • H-scan analysis, a matched-filter approach using Gaussian-weighted Hermite polynomial functions.
  • Application of H-scan to ultrasound images from 46 patients with thyroid lesions.
  • Analysis of phantoms with spherical scatterers to obtain independent reference values.

Main Results:

  • H-scan analysis revealed statistically significant differences in channel outputs between normal thyroid, benign, and cancerous lesions.
  • Phantom studies provided baseline data for H-scan output interpretation.
  • The study identified specific H-scan measures that correlate with different thyroid tissue categories.

Conclusions:

  • H-scan analysis shows potential as a quantitative tool for thyroid lesion characterization.
  • This method may aid in distinguishing between normal, benign, and malignant thyroid tissues.
  • Further research with larger cohorts is warranted to validate H-scan's clinical utility.
