We present methods for fabrication of patterned microstructures of vertically aligned carbon nanotubes (CNTs), and their use as master molds for production of polymer microstructures with organized nanoscale surface texture. The CNT forests are densified by condensation of solvent onto the substrate, which significantly increases their packing density and enables self-directed formation of 3D shapes.

Regulation of Water Intake

Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Improved Polydimethylsiloxane (PDMS) Double Casting via Silicone Oil Treatment for Densely Packed Microstructure Replication
0 Views •
2025
This protocol presents an improved demolding procedure for the Polydimethylsiloxane (PDMS) double casting technique by introducing silicone oil as a non-adhesive barrier between PDMS layers. Unlike plasma or chemical surface modification methods, this approach requires no specialized or costly equipment, making it a more accessible and cost-effective alternative.
FAQs
Bout size reflects how much is consumed during an individual intake episode, whereas eating rate describes how quickly that episode unfolds. Examining both measures can help separate altered hunger or motivation from changes in meal termination. For example, a condition may change the amount consumed per bout, the speed of eating, or both, even when total intake appears similar.
The interval separating intake bouts adds a temporal dimension that total consumption cannot provide. Shorter or longer gaps may indicate changes in how feeding is organized across time, while bout duration and size show what happens within an episode. Together, these measures characterize the sequence of feeding behavior and help identify alterations in appetite regulation or satiety.
The method compares several features rather than relying on one intake value. Changes in bout size, duration, eating rate, and the spacing of bouts can produce different behavioral patterns. This multidimensional profile helps investigators evaluate whether an intervention is associated with meal termination, hunger, motivation, or another aspect of feeding organization, rather than assuming every intake reduction has the same cause.
A study records individual intake events over time and quantifies the characteristics of those events. Core measurements identified in this approach include bout size, bout duration, eating rate, and intervals between bouts. Organizing the observations in this way allows researchers to examine both the properties of each intake episode and the timing of feeding across the observation period.
Researchers use this approach when the scientific question concerns how feeding unfolds, not simply how much food or fluid is consumed. It is relevant when studying appetite regulation, obesity, metabolic disease, or the effects of medications and physiological interventions. The detailed pattern can reveal behavioral changes that a single total-intake measurement might conceal.
In medicine and behavioral neuroscience, the measurements provide behavioral evidence that can be related to underlying biological mechanisms. Investigators can compare intake patterns across physiological interventions, medications, or disease-related conditions and assess changes in hunger, satiety, motivation, or meal termination. This supports interpretation of feeding behavior in research on appetite regulation, obesity, and metabolic disease.
