A method to culture an endothelial cell monolayer throughout the entire inner 3D surface of a microfluidic device with microvascular-sized channels (<30 μm) is described. This in vitro microvasculature model enables the study of biophysical interactions between blood cells, endothelial cells, and soluble factors in hematologic diseases.

Biomarkers in an Animal Model for Revealing Neural, Hematologic, and Behavioral Correlates of PTSD

We describe a rat model of post traumatic stress disorder (PTSD) that reveals the persistent alterations in neuroendocrine function and the delayed long-term, exaggerated fear response, characteristic of PTSD patients. The animal model and methods described here are useful for correlating biomarkers in brain nuclei, which are mechanistic but cannot be measured in patients, with biomarkers in peripheral white blood cells, which can.

Working capital is a key indicator of a company’s short-term financial strength and operational efficiency. Defined as current assets minus current liabilities, it measures the firm's capacity to manage day-to-day financial obligations. In financial analysis, shifts in working capital are especially significant when reviewing the cash flow statement.In the operating section of the cash flow statement, changes in working capital explain how operational decisions affect cash availability. When...

Analyzing Situations in Helping Behavior

Source: Julian Wills & Jay Van Bavel—New York University Social psychologists and personality psychologists both attempt to predict human behavior, but they focus on very different factors. Whereas personality psychologists focus on how personality traits, character, and individual differences affect behavior, social psychologists focus primarily on the power of social situations in shaping behavior. We often underestimate the role that social situations can play in determining behavior. We...
FAQs
These instruments can distinguish blood cells through electrical impedance or light-based analysis after the sample has been diluted. The resulting signals support enumeration and characterization of red blood cells, white blood cells, and platelets. Using these detection approaches, a hematological analyzer produces standardized measurements that can reveal changes in cell numbers and cellular patterns relevant to immune and infectious processes.
Anticoagulated blood helps preserve the sample in a form suitable for analysis, while dilution prepares the cellular suspension for instrumental detection. Together, these preparation steps support consistent measurement of blood-cell populations. Their role is especially important when comparing leukocyte counts, platelet results, or other cellular characteristics across samples collected during disease evaluation or treatment monitoring.
Leukocyte differential analysis separates information about white blood cell populations rather than relying only on a total count. This added detail helps researchers evaluate immune status, inflammation, and infection-related changes in cellular composition. It can also support comparisons between experimental groups or time points when investigators study disease progression, immune responses, or treatment-associated effects.
Beyond reporting cell counts, the analysis provides cellular characteristics that may indicate abnormal blood-cell patterns. In immunology and infection studies, these patterns can contribute to evaluation of altered immune status or inflammation. The results do not replace broader investigation, but they provide a reproducible laboratory readout for recognizing changes that warrant interpretation alongside the study or clinical context.
The workflow begins with an anticoagulated blood sample, followed by dilution and instrumental detection of the cells. Depending on the analyzer, electrical impedance or light-based analysis generates measurements for red blood cells, white blood cells, and platelets. The instrument then reports counts and cellular characteristics that can be used for differential analysis, comparison, and further interpretation.
They are useful when investigators need rapid, standardized measurements of circulating blood cells during clinical diagnostics, experimental studies, or disease monitoring. In infection and immunology research, repeated measurements can help evaluate leukocyte patterns, inflammation-related changes, and shifts associated with treatment. Automated processing also improves testing speed, standardization, and reproducibility across samples or study time points.
Counts and cellular characteristics provide measurable outcomes for comparing blood samples before and after treatment or across different experimental conditions. Researchers can examine changes in leukocyte populations, abnormal cellular patterns, and broader blood-cell results to assess whether the immune or inflammatory profile has shifted. Automation supports this comparison by producing faster and more reproducible measurements.
