Summary
Biomonitoring of etheno-DNA adducts, formed by lipid peroxidation products, can identify cancer hazards. These adducts are elevated in cancer-prone individuals, highlighting their role in disease progression and therapeutic monitoring.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- Oxidative stress and lipid peroxidation (LPO) contribute to carcinogenesis.
- Etheno-DNA adducts, derived from LPO products like 4-hydroxy-2-nonenal, are potent mutagens.
- Chronic inflammation and infections can exacerbate these processes.
Purpose of the Study:
- To investigate the role of etheno-DNA adducts in carcinogenesis.
- To assess the utility of ultra-sensitive detection methods for these adducts.
- To explore the potential of biomonitoring adducts for disease management.
Main Methods:
- Development of ultra-sensitive detection assays for etheno-adducts.
- Analysis of adduct levels in human tissues, white blood cells (WBC), and urine.
- Review of studies on DNA damage in mother-newborn pairs and liver disease patients.
Main Results:
- Elevated etheno-adducts were observed in affected organs of cancer-prone patients.
- DNA damage in WBC of mother-newborn pairs was analyzed.
- Lipid peroxidation-derived DNA damage was assessed in patients with liver diseases.
Conclusions:
- Biomonitoring of etheno-DNA adducts is a promising tool for understanding disease aetiopathogenesis.
- Adduct levels can aid in hazard identification and disease progression monitoring.
- Clinical trials are warranted to verify the efficacy of interventions using adduct biomonitoring.

01:20Blood Studies for Cardiovascular System I: Cardiac Biomarkers
715
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
479
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

01:12Hazard Ratio
519
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

01:11Hazard Rate
360
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...
