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...

Random and Systematic Errors

15.1K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Systematic Sampling Method

13.3K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

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
This summary is machine-generated.

Aerobic exercise may enhance Brain-derived neurotrophic factor (BDNF) levels after stroke, particularly in the central nervous system. However, more human studies are needed to confirm the effects of functional training on BDNF post-stroke.

Area of Science:

  • Neuroscience
  • Rehabilitation Medicine
  • Exercise Physiology

Background:

  • Brain-derived neurotrophic factor (BDNF) is crucial for neuroplasticity.
  • Physical exercise may positively influence BDNF release and brain plasticity.
  • This has implications for brain injury recovery and rehabilitation.

Purpose of the Study:

  • To systematically review literature on aerobic exercise and functional task training effects on post-stroke BDNF concentrations.
  • To investigate findings in both human and animal models.

Main Methods:

  • Searched PubMed, SCOPUS, CINAHL, MEDLINE, and Cochrane databases (2004-2017).
  • Included 21 articles, assessing methodological quality using ARRIVE Guidelines (animals) and PEDro Scale (humans).
  • BDNF levels were measured systemically or centrally.

Main Results:

  • Aerobic exercise appears to promote changes in central BDNF concentrations post-stroke.
  • Evidence for BDNF response to functional exercises (e.g., CIMT) post-stroke is currently controversial.
  • Only one human study evaluated post-stroke BDNF following exercise; 20 studies used animal models.

Conclusions:

  • Aerobic exercise shows promise for increasing central BDNF post-stroke, primarily based on animal data.
  • Further human research is essential to clarify the impact of functional training on BDNF levels after stroke.
  • Current conclusions rely heavily on animal models due to limited human studies.
