Here, we present an enhanced yeast one-hybrid screening protocol to identify the transcription factors (TFs) that can bind to a human DNA region of interest. This method uses a high-throughput screening pipeline that can interrogate the binding of >1,000 TFs in a single experiment.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide: This solubility equilibrium may be shifted left by the addition of either silver or iodide ions, resulting in...

We present a protocol that uses functional magnetic resonance imaging to investigate the neural correlates of the memory-enhancing effect of emotion. This protocol allows identification of brain activity specifically linked to memory-related processing, contrary to more general perceptual processing, and can be used with healthy and clinical populations.

Bioavailability Enhancement: Drug Permeability Enhancement

After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt secretion,...

Within the liquid film, the dissolved species is consumed after crossing the interface. That reaction keeps the local concentration lower than it would be during nonreactive uptake, so the concentration difference through the film remains larger. The resulting transport increase reflects the coupling between reaction rate and diffusion, rather than either process acting independently.
The enhancement factor responds to several linked properties: reaction kinetics determine how quickly the dissolved species is consumed, while diffusivity controls movement through the liquid film and solubility affects entry into the liquid. Operating conditions also matter because they influence the relative importance of these processes and therefore the reaction-assisted transport predicted for the equipment.
Compared with physical absorption or diffusion alone, a reactive liquid film can sustain a stronger driving gradient without changing the underlying need for interfacial transfer. The useful comparison is therefore the transport rate with reaction versus the corresponding nonreactive case. This distinction lets engineers separate reaction-assisted performance from ordinary dissolution and diffusion.
An engineering analysis can begin with the nonreactive mass-transfer case, then incorporate the reaction occurring in the liquid film. The analyst evaluates kinetics, diffusivity, solubility, and operating conditions to determine the factor and applies it to estimate the reaction-assisted flux. This sequence connects transport behavior with calculations for mass-transfer equipment.
For an absorber or membrane contactor, the factor provides a way to account for chemical reaction when estimating mass-transfer performance. Engineers can compare predicted reaction-assisted fluxes under different operating conditions and use those estimates in equipment analysis. The same reasoning extends to other mass-transfer equipment where a dissolved species reacts during transport.
Applications include gas treatment, carbon capture, and chemical processing, especially where a gas-phase species dissolves and reacts in a liquid. In these settings, the factor helps connect reaction and diffusion effects to engineering decisions about mass-transfer equipment. Its value supports analysis under specified operating conditions rather than serving as an isolated material property.
