Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual mental imagery refers to the ability to conjure images in one’s mind’s eye. This allows people to process visual material above and beyond the constraints of a current point-of-view; for example, a person could imagine, using their mind’s eye, how something might look in a different color, or what it would look like if it were made from a different material or rotated and seen from a different perspective. Mental imagery...

Operant drug self-administration and conditioned place preference (CPP) procedures are expansively used in research to model various components of drug reinforcement, consumption, and addiction in humans. In this report, we combined traditional CPP and self-administration methods as a novel approach to studying drug reinforcement and addiction in rats.

Properly folded and assembled proteins are selectively packaged into vesicles that exit the ER. Motor proteins transport these vesicles to the Golgi apparatus for adding modifications that make these proteins functional at their destination. The Golgi apparatus is a eukaryotic organelle that has a distinctive ribbon-like appearance. It is a primary sorting and dispatch station for cargo arriving from the ER. Newly arriving vesicles enter the cis face of the Golgi, closest to the ER, and are...

As they leave the Endoplasmic Reticulum (ER), properly folded and assembled proteins are selectively packaged into vesicles. These vesicles are transported by microtubule-based motor proteins and fuse together to form vesicular tubular clusters, subsequently arriving at the Golgi apparatus, a eukaryotic endomembrane organelle that often has a distinctive ribbon-like appearance.The Golgi apparatus is a major sorting and dispatch station for the products of the ER. Newly arriving vesicles enter...
FAQs
The mesh basket retains the tablet or capsule while allowing dissolution medium to contact the dosage form during rotation. This arrangement keeps the formulation positioned within the liquid and helps create consistent fluid movement around it. By controlling the formulation’s location and exposure, the apparatus supports reproducible measurement of active-ingredient release over time.
Controlled rotation speed and specified medium temperature help standardize the conditions surrounding the dosage form. These settings influence the fluid movement and environment in which release occurs, so maintaining them consistently improves comparability among measurements. Reproducible conditions are essential when researchers compare formulations, assess batches, or evaluate compliance with dissolution specifications.
A dissolution profile shows how the amount of active ingredient released changes over the sampling period. Its time-based pattern can support comparisons among formulations and indicate whether a dosage form follows established dissolution specifications. In pharmaceutical research, this information helps connect formulation changes with measurable release behavior rather than relying only on a single observation.
Testing places the tablet or capsule in the mesh basket, immerses it in the selected dissolution medium, and rotates the basket at the specified speed and temperature. Samples are then collected at defined points over time and analyzed for active-ingredient release. The resulting measurements are assembled into a dissolution profile for interpretation against the study purpose or specification.
During formulation development, release profiles allow researchers to examine how an oral dosage form releases its active ingredient into liquid medium. Comparing profiles can help identify whether formulation changes alter release behavior. This provides an in vitro basis for selecting and refining formulations before using the method for broader pharmaceutical evaluation or quality-related testing.
Quality-control teams can compare release profiles from manufactured batches with established dissolution specifications. Consistent agreement supports assessment of batch-to-batch consistency, while differences identify release behavior that may require further investigation. Because the test uses controlled fluid movement, temperature, rotation, and sampling, it provides a standardized way to evaluate oral dosage-form performance.
