First Pass Effect

Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs. Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

Determining the Mass Percent Composition in an Aqueous Solution

Source: Laboratory of Dr. Neal Abrams — SUNY College of Environmental Science and Forestry Determining the composition of a solution is an important analytical and forensic technique. When solutions are made with water, they are referred to as being aqueous, or containing water. The primary component of a solution is referred to as the solvent, and the dissolved minor component is called the solute. The solute is dissolved in the solvent to make a solution. Water is the most common solvent in...

Single-pass Transmembrane Proteins

Integral membrane proteins are tightly associated with the cell membrane and play a crucial role in cell communication, signaling, adhesion, and transport of the molecules. Some integral membrane proteins are present only in the membrane monolayer. For example, the enzyme fatty acid amide hydrolase is present in the cytoplasmic side of the membrane monolayer. In contrast, another type of integral membrane protein, also known as a transmembrane protein, spans across the membrane. Transmembrane...

Bond Polarity, Dipole Moment, and Percent Ionic Character

Bond Polarity The absolute value of the difference in electronegativity (ΔEN) of two bonded atoms provides a rough measure of the polarity to be expected in the bond and, thus, the bond type. When the difference is very small or zero, the bond is covalent and nonpolar. When it is large, the bond is polar covalent or ionic. The absolute values of the electronegativity differences between the atoms in the bonds H–H, H–Cl, and Na–Cl are 0 (nonpolar), 0.9 (polar covalent), and 2.1 (ionic),...

100-Percent-Reserve Banking

Imagine an economy without any banks; the entire money supply is held by the public in the form of physical currency. This means that the amount of money in the economy is equal to the total value of currency held by households and firms.Now, a commercial bank is introduced, and the public is assumed to deposit all their currency into the bank. If the bank does not issue any loans and instead holds all the deposited money in reserve, it is known as a 100-percent-reserve banking system. In this...
FAQs
Acceptance criteria determine which tested units count as passing, so the metric reflects performance against a stated standard rather than an undefined judgment. Because the calculation uses both passing units and all evaluated units, changing the criterion or the set of units assessed can change the result. Clear, consistent criteria support meaningful comparisons across batches or conditions.
A batch-level comparison can reveal whether performance remains consistent or varies between groups of biological samples, assays, or experiments. Examining results under different conditions helps researchers identify process variation rather than relying on a single overall impression. This comparison supports quality monitoring and highlights workflows that may need closer evaluation for reproducibility.
A changing rate over time may indicate emerging or recurring inconsistency in a laboratory workflow. Tracking the measure across successive evaluations helps researchers recognize patterns that a single result could miss, although the metric alone does not identify the cause. These trends can guide further review of sample quality, experimental reliability, or other process conditions.
First, researchers apply the predefined acceptance criteria to each evaluated sample, assay, experiment, or other tested unit. They then count the units that pass, record the total number assessed, divide the passing count by that total, and multiply by 100. Recording the associated batch or condition preserves the context needed for later comparison.
When biological results must be reviewed for quality, the pass rate provides a summary of how many evaluated units met the established standard. Researchers can use that information alongside the underlying criteria and evaluation records when considering data inclusion. It helps distinguish broadly reliable sets from groups requiring closer examination without replacing the detailed assessment of individual units.
The metric can be applied to biological samples, assays, experiments, and other tested units for which researchers have defined acceptance criteria. It can support sample-quality monitoring, assessment of experimental reliability, and evaluation of process consistency. Because the same calculation can be compared across batches or conditions, it provides a common quality-control view across different laboratory activities.
