A new electron paramagnetic resonance (EPR) method, rapid scan EPR (RS-EPR), is demonstrated for 2D spectral spatial imaging which is superior to the traditional continuous wave (CW) technique and opens new venues for in vivo imaging. Results are demonstrated at 250 MHz, but the technique is applicable at any frequency.

Homeostasis Conditions in the external environment of an organism can change rapidly and drastically. To survive, organisms must maintain a fairly constant internal environment, which involves continuous regulation of temperature, pH, and other factors. This balanced state is known as homeostasis, which describes the processes by which organisms maintain their optimal internal conditions. To maintain homeostasis, organisms have developed structures with distinct functions. Physiology is the...

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The autonomic nervous system (ANS) controls the activity of the body's internal organs and regulates changes in their activity depending on the current environment. The vagus nerve, which innervates many of the internal organs, is an important part of the system. When our brain senses danger, vagal tone is inhibited, leading to a set of changes in the body designed to make us more prepared to fight or...

The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...
FAQs
Homeostatic feedback mechanisms detect changes in an organism’s internal conditions and adjust physiological processes in response. Because cellular and organ activities are coordinated, these adjustments help maintain relatively stable conditions rather than allowing every measurement to change independently. Observing how a parameter shifts and returns toward its usual state can therefore provide evidence of regulatory function.
Physiological parameters reflect the combined activity of cells and organs, so environmental stress, disease, or treatment can alter the internal state they indicate. Researchers can compare measurements across experimental conditions to identify these effects quantitatively. The comparison is most informative when the same parameter is examined consistently across the relevant individuals, tissues, or conditions.
A single measurement may describe only one aspect of biological function, whereas a set of parameters can reflect activity across multiple physiological processes. Examining body temperature, heart rate, blood pressure, respiration, or hormone levels together helps researchers relate cellular and organ responses to overall internal regulation. This broader view supports more informative assessments of health and biological responses.
Researchers first identify the parameter relevant to the biological question, obtain measurements from comparable individuals, tissues, or experimental conditions, and then examine differences among those measurements. The resulting quantitative comparisons can indicate changes in health, environmental response, disease progression, or treatment effects. Interpretation should remain connected to the physiological process represented by each measurement.
They are useful when researchers need measurable evidence of an organism’s internal response. Monitoring can support studies of health, environmental stress, disease progression, and treatment effects. Because the measurements connect observable outcomes with biological function, they are relevant across physiology, medicine, ecology, and biomedical science, where researchers compare responses among organisms or experimental conditions.
Physiological measurements provide an observable way to study the consequences of coordinated cellular and organ activities. For example, changes in respiration, hormone levels, or cardiovascular measurements can be considered alongside the organism’s internal state. This connection allows biology researchers to relate processes occurring at cellular and organ levels to health, regulation, stress responses, and disease-related changes.
