Source: Tamara M. Powers, Department of Chemistry, Texas A&M University Today's modern world requires the use of a large amount of energy. While we harness energy from fossil fuels such as coal and oil, these sources are nonrenewable and thus the supply is limited. To maintain our global lifestyle, we must extract energy from renewable sources. The most promising renewable source, in terms of abundance, is the sun, which provides us with more than enough solar energy to fully fuel our...

We describe a protocol for the rapid and sensitive quantification of disease severity in mouse models of cerebellar ataxia. Measures include hind limb clasping, ledge test, gait and kyphosis. This protocol effectively discriminates between affected and non-affected individuals, and detects the progression of affected individuals over time.

Microfluidic flow chambers etched by photolithography and fabricated from PDMS are applied to probe functional outcomes associated with EC dysfunction and inflammation. In a representative experiment, the ability of differential shear stress to modulate monocytic cell adhesion to cytokine activated EC monolayers is demonstrated.
FAQs
A positive allergen-specific immunoglobulin E result or skin-prick test provides evidence of immune reactivity, but it does not by itself describe the patient’s clinical pattern. Interpretation becomes more informative when the result is compared with reported symptoms and relevant exposure history. This combined assessment helps distinguish meaningful patient differences and supports more precise characterization of hypersensitivity-related disease.
Allergen-specific immunoglobulin E and skin-prick testing supply direct evidence that the immune system reacts to a particular allergen. Inflammatory biomarkers can sometimes add information about the patient’s biological profile beyond sensitization testing. Because these measurements capture different aspects of the clinical picture, combining them with symptoms and exposure history can improve patient stratification.
Sensitization Phenotypes organize patients according to patterns of immune reactivity and associated clinical findings. This framework helps account for why similar exposures may produce different outcomes among individuals. Differences in sensitization evidence, symptoms, exposure history, and sometimes inflammatory biomarkers can reveal clinically meaningful subgroups, supporting more individualized risk assessment and investigation of disease mechanisms.
The assessment begins by documenting symptoms and the patient’s relevant exposure history. Clinicians then examine evidence of sensitization, such as allergen-specific immunoglobulin E or a positive skin-prick test, and may include inflammatory biomarkers when appropriate. These findings are considered together rather than in isolation, producing a clinically defined pattern that can support diagnosis and patient stratification.
They are particularly useful when evaluating allergic rhinitis, asthma, and food allergy, where patients can show different relationships between immune reactivity and symptoms. Characterizing these patterns can support more precise diagnosis, help assess risk, and contribute to selection of targeted treatments. The approach also provides a way to organize clinically relevant differences across patients with related hypersensitivity conditions.
In research, these phenotypes provide a framework for stratifying patients according to sensitization evidence, clinical symptoms, exposure history, and selected inflammatory biomarkers. Such grouping helps investigators examine why similar exposures lead to different clinical outcomes and can support studies of targeted treatment approaches. The framework therefore connects measurable immune reactivity with clinically relevant variation across diseases.
