In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

What are Cells?

199.6K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

What is Cell Signaling?

130.4K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Chemistry of the Cell02:58

Chemistry of the Cell

48.0K
The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...

Concentration Cells02:41

Concentration Cells

25.9K
A concentration cell is a type of a  voltaic cell constructed by connecting two almost identical half-cells, both based on the same half-reaction and using the same electrode, differing only in the concentration of one redox species. A concentration cell's potential, therefore, is determined only by the concentration difference of the particular redox species.
Consider the following voltaic cell:

Summary

Giant cell arteritis (GCA) is a common large vessel vasculitis. Tocilizumab effectively reduces GCA relapses and lowers the required steroid dosage, improving patient outcomes.

Area of Science:

  • Rheumatology
  • Immunology
  • Vasculitis Research

Background:

  • Giant cell arteritis (GCA) is the most prevalent form of large vessel vasculitis.
  • GCA classically presents with headaches, scalp tenderness, visual disturbances, and polymyalgic symptoms.
  • Current primary treatment involves high-dose corticosteroids, often necessitating steroid-sparing agents.

Purpose of the Study:

  • To evaluate the efficacy of tocilizumab in managing giant cell arteritis.
  • To assess tocilizumab's impact on relapse rates in GCA patients.
  • To determine the effect of tocilizumab on cumulative corticosteroid dosage.

Main Methods:

  • Clinical trials investigating tocilizumab for GCA.
  • Analysis of relapse rates in patients treated with tocilizumab compared to standard care.
  • Monitoring of cumulative steroid dose in patients receiving tocilizumab.

Main Results:

  • Tocilizumab significantly reduced the relapse rate in patients with giant cell arteritis.
  • Treatment with tocilizumab led to a lower cumulative corticosteroid dose.
  • Methotrexate demonstrated some utility in reducing steroid dependence.

Conclusions:

  • Tocilizumab is an effective therapy for giant cell arteritis, significantly lowering relapse rates.
  • Tocilizumab facilitates a reduction in long-term corticosteroid exposure.
  • Tocilizumab offers a valuable therapeutic option for managing GCA and mitigating steroid toxicity.
