Tumor Progression02:07

Tumor Progression

7.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

365
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

The Nucleolus02:55

The Nucleolus

10.4K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Reaction Rate02:53

Reaction Rate

66.1K
The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

Area of Science:

  • Biomedical research
  • Microbiology
  • Orthopedics

Background:

  • Degenerative intervertebral disc disease is complex, influenced by mechanical stress, nutritional deficits, and inflammation.
  • Propionibacterium acnes (P. acnes) has been increasingly detected in degenerated discs, suggesting a potential role.

Purpose of the Study:

  • To review existing literature on P. acnes and degenerative intervertebral disc.
  • To elucidate the pathways of P. acnes entry into the intervertebral disc.
  • To explore the mechanisms by which P. acnes exacerbates disc degeneration.

Main Methods:

  • Literature review of studies investigating P. acnes and intervertebral disc degeneration.
  • Deductive reasoning to propose P. acnes entry mechanisms.
  • Analysis of proposed mechanisms for P. acnes-induced disc degeneration.

Main Results:

  • P. acnes is frequently found in degenerated intervertebral discs.
  • Proposed pathways for P. acnes to infiltrate the disc environment.
  • Hypothesized mechanisms of P. acnes contributing to disc tissue damage and degeneration.

Conclusions:

  • P. acnes is a potential factor in degenerative intervertebral disc disease.
  • Understanding P. acnes' role may lead to novel therapeutic strategies.
  • Further research is warranted to confirm P. acnes' causative link and develop targeted treatments.
