Tumor Progression02:07

Tumor Progression

7.4K
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

4.7K
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...

Rapidly Varying Flow01:24

Rapidly Varying Flow

474
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

RACE - Rapid Amplification of cDNA Ends02:35

RACE - Rapid Amplification of cDNA Ends

7.2K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

The Nucleolus02:55

The Nucleolus

10.3K
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

62.6K
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:

  • Nephrology
  • Immunology
  • Pathology

Background:

  • Rapid progressive glomerulonephritis (RPGN) is a medical emergency characterized by rapid loss of renal function.
  • Histological findings, particularly immunofluorescence patterns, classify RPGN into distinct categories, guiding treatment strategies.
  • Advances in immunosuppressive therapies have improved outcomes for conditions like ANCA-associated vasculitis.

Purpose of the Study:

  • To summarize the current understanding of rapid progressive glomerulonephritis (RPGN).
  • To highlight the importance of early diagnosis and treatment in improving renal function prognosis.
  • To review histological classification and emerging therapeutic approaches.

Main Methods:

  • Review of histological findings using immunofluorescence to classify RPGN.
  • Analysis of prognostic markers, emphasizing creatinine levels at treatment initiation.
  • Evaluation of current and emerging immunosuppressive treatment regimens.

Main Results:

  • RPGN can be classified into three immunofluorescence patterns: ANCA-associated vasculitis, anti-GBM disease, and granular deposition diseases (e.g., SLE).
  • Early creatinine levels are a key prognostic indicator for RPGN.
  • Improved immunosuppressive therapies, including rituximab, have enhanced treatment induction for ANCA-associated vasculitis.

Conclusions:

  • Early diagnosis and treatment are crucial for improving prognosis in RPGN.
  • Immunofluorescence classification aids in understanding RPGN pathogenesis and guiding therapy.
  • While prognosis has improved, challenges remain regarding optimal treatment duration and recurrence monitoring.
