An efficient method to obtain highly purified viable meiotic fractions from mouse testis is described, which combines a refined cell dissociation protocol with fluorescent activated cell sorting (FACS). This method takes advantage of differences in the DNA content and nuclear density of discrete meiotic fractions.

The micronucleus (MN) assay is a well-established test for quantifying DNA damage. However, scoring the assay using conventional techniques such as manual microscopy or feature-based image analysis is laborious and challenging. This paper describes the methodology to develop an artificial intelligence model to score the MN assay using imaging flow cytometry data.

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...

Contrast Enhanced Ultrasound imaging is a reliable in-vivo tool for quantifying spinal cord blood flow in an experimental rat spinal cord injury model. This paper contains a comprehensive protocol for application of this technique in association with a contusion model of thoracic spinal cord injury.
FAQs
Increasing or redirecting a pressure gradient can reduce the resistance that limits fluid movement, allowing greater velocity or throughput through a system. This approach is especially relevant when a design must deliver nutrients, oxygen, cells, or therapeutic compounds reliably. Researchers can therefore use pressure conditions to improve transport while also considering energy requirements and the need to reproduce physiological movement.
Channel geometry changes how readily fluid moves through a system and can also influence mixing. Adjusting the shape or dimensions of a channel may improve throughput without relying on the same pressure conditions used in another design. In bioengineering, this principle helps tailor microfluidic devices and other transport systems to their intended delivery or processing requirements.
Surface properties can alter the interaction between a fluid and the channel or device boundary, while viscosity affects how readily the fluid moves. Changing either factor can reduce resistance and improve velocity, throughput, or mixing. These variables give bioengineers additional design options when pressure or geometry alone cannot provide the desired transport behavior.
Selection begins with the transport outcome the system must achieve, such as improved delivery, higher throughput, stronger mixing, or closer reproduction of physiological conditions. Researchers can then consider pressure gradients, channel geometry, surface properties, and viscosity as alternative or complementary control variables. The preferred strategy is the one that improves transport while supporting efficiency and reliable operation.
Bioengineering applications include microfluidic devices, bioreactors, medical implants, and engineered tissues. In these settings, improved movement can support the delivery of nutrients, oxygen, cells, or therapeutic compounds. The same design principle can therefore address both small-scale device transport and larger biological or processing systems that require controlled, dependable fluid movement.
Controlled transport allows researchers to reproduce aspects of physiological fluid movement when studying biological systems. Improving flow can also increase process efficiency and reduce energy requirements, which supports the development of scalable technologies. Together, these benefits connect laboratory transport designs with studies of engineered tissues, medical systems, and production-oriented bioengineering platforms.
