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...

Nanoscopic Imaging of Human Tissue Sections via Physical and Isotropic Expansion09:11

Nanoscopic Imaging of Human Tissue Sections via Physical and Isotropic Expansion

Nanoscale imaging of clinical tissue samples can improve understanding of disease pathogenesis. Expansion pathology (ExPath) is a version of expansion microscopy (ExM), modified for compatibility with standard clinical tissue samples, to explore the nanoscale configuration of biomolecules using conventional diffraction limited...

An Ex Vivo Tissue Culture Model for Fibrovascular Complications in Proliferative Diabetic Retinopathy08:10

An Ex Vivo Tissue Culture Model for Fibrovascular Complications in Proliferative Diabetic Retinopathy

Here, we present a protocol to study the pathophysiology of proliferative diabetic retinopathy by using patient-derived, surgically-excised, fibrovascular tissues for three-dimensional native tissue characterization and ex vivo culture. This ex vivo culture model is also amenable for testing or developing new...

Natural Killer Cell Isolation from Liver Tissue for Selective Expansion04:17

Natural Killer Cell Isolation from Liver Tissue for Selective Expansion

This video demonstrates the isolation of lymphocytes, including natural killer cells or NK cells, from human liver tissue for selective expansion. Enzymatic and mechanical digestion, followed by density gradient separation, promotes lymphocyte isolation, including NK cells. The collected lymphocytes can be further used for the selective expansion of NK...
