Summary
Fourier transform infrared (FTIR) spectroscopy revealed metabolic and structural changes in thyroid tissue, distinguishing between benign tumors, malignant neoplasms, and healthy tissue. This technique identified the Warburg effect in malignant neoplasms.
Area of Science:
- Biochemistry
- Spectroscopy
- Endocrinology
Background:
- Thyroid cancer is the most common endocrine malignancy, with diagnosis relying on ultrasonography (USG) TI-RADS, clinical symptoms, and biopsies (Bethesda System).
- Biomarkers and advanced spectroscopic techniques can further support thyroid nodule diagnosis.
Purpose of the Study:
- To compare chemometric changes using Fourier transform infrared (FTIR) spectroscopy between benign tumors (BT) and malignant neoplasms (MN).
- To analyze differences between thyroid pathology (TP) and healthy tissue (HT) using FTIR spectroscopy.
Main Methods:
- Thyroid nodular disease biopsies were analyzed using Attenuated Total Reflectance-FTIR (ATR-FTIR) spectroscopy.
- Biomolecular compounds of BT vs. MN and TP vs. HT were compared.
- Pre-biopsy data included laboratory blood tests, USG TI-RADS classification, and Bethesda cytopathology reports.
Main Results:
- Malignant neoplasms (MN) showed increased creatinine and decreased albumin compared to benign tumors (BT).
- FTIR analysis revealed metabolic alterations in MN, indicative of the Warburg effect, with increased protein to lipid/DNA ratios.
- Thyroid pathology (TP) exhibited structural changes in lipids, fatty acids, amide III, and nucleic acids compared to healthy tissue (HT).
Conclusions:
- Metabolic alterations, including the Warburg effect, characterize malignant neoplasms, with decreased lipids and DNA relative to protein content.
- Significant structural changes in key biomolecules were observed in thyroid pathology compared to healthy tissue.
- Further research is warranted to fully elucidate the diagnostic potential of FTIR spectroscopy in thyroid diseases.

01:09Infrared (IR) Spectroscopy: Overview
6.8K
When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.

01:29UV–Vis Spectroscopy: Woodward–Fieser Rules
30.7K
UV–Visible absorption spectra of conjugated dienes arise from the lowest energy π → π* transitions. The light-absorbing part of the molecule is called the chromophore, and the substituents directly attached to the chromophore are called auxochromes. A strong correlation exists between the absorption maxima, λmax, and the structure of a conjugated π system. The Woodward–Fieser rules predict the value of λmax for a...

01:25IR Spectrometers
3.1K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

01:03IR Frequency Region: Fingerprint Region
2.1K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

1.5K
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.

28
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...
