Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

5.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

114
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

The Ras Gene02:38

The Ras Gene

6.3K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Positron Emission Tomography01:29

Positron Emission Tomography

4.3K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Isotopes and Radioisotopes01:28

Isotopes and Radioisotopes

8.6K
In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.
An isotope containing...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

151
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Summary
This summary is machine-generated.

Radon progeny exposure during pregnancy may pose risks. Radon-220 decay products, particularly polonium-212, could be significant alpha particle emitters in the prenatal period, warranting further study for childhood cancer risks.

Area of Science:

  • Environmental Health
  • Radiation Biology
  • Pediatric Oncology

Background:

  • Radon is a known carcinogen, but its prenatal effects are understudied.
  • Radon progeny inhalation is a significant source of radiation exposure.
  • The specific risks of radon progeny during fetal development require investigation.

Purpose of the Study:

  • To explore the potential carcinogenicity of radon progeny on the human body during the prenatal period.
  • To analyze the dose contribution of radon-220 progeny during gestation.
  • To highlight the importance of considering radon-220 decay products in future research on childhood neoplasms.

Main Methods:

  • Analysis of half-lives of radon-222 and radon-220 and their progeny.
  • Theoretical consideration of alpha particle emission during the prenatal period.
  • Comparison of precursor half-lives for polonium-214 and polonium-212.

Main Results:

  • Radon-220 progeny may significantly impact the prenatal period despite lower overall radon concentration.
  • The precursors of polonium-212 have longer half-lives than those of polonium-214.
  • Polonium-212, a radon-220 decay product, is theoretically a predominant alpha particle emitter in utero.

Conclusions:

  • Radon-220 decay products, especially polonium-212, warrant attention for prenatal radiation exposure.
  • Future studies on prenatal radon exposure and childhood cancer should account for radon-220 progeny.
  • Understanding these risks is crucial for protecting fetal health from carcinogenic factors.
