Biological homeostasis is a state of steady internal, physical, and chemical conditions maintained by a living organism observed at the cellular level. Biological homeostasis can vary in order to alter the cellular physical and chemical conditions.
In medical diagnostic procedures for examining the cervix and the tissues of the vagina and vulva, long working-distance (-30 cm) lighted binocular microscopes (colposcope) that provide up to 25x optical magnification are used to create an illuminated magnified view. Speculum dilations can give rise to specular reflections from the tissue surface, causing physicians to overlook possible abnormalities – thus decreasing the quality of a colposcopy.
Traumatic brain injury (TBI) is a major health problem. Between 3.2 and 5.3 million people live with long-term disabilities resulting from TBI, and thus, contribute to the need to develop therapies that treat TBI-induced cellular damage. Researchers at the National Institute of Child Health and Human Development (NICHD) have developed a device that simulates the pressure waves resulting from explosions.
Scientists at the Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) have developed a method implemented as pulse sequences and software to be used with magnetic resonance imaging (MRI) scanners and systems. This technology is available for licensing and commercial development. The method allows for measuring and mapping features of the bulk or average apparent diffusion coefficient (ADC) of water in tissue – aiding in stroke diagnosis and cancer therapy assessment.
This technology includes a microscopy method that reduces the speed penalty at least 1000-fold, while retaining resolution improvement. A Digital mirror device (DMD) or sweptfield confocal unit is used to create hundreds to thousands of excitation foci that are imaged to a sample mounted in a conventional microscope and record the resulting emissions on an array detector. Detection of each confocal spot is done in our proprietary software, as is the processing and deconvolution that is used for a 2x resolution enhancement.
The technology includes MRI methods, systems, and software for reliably imaging vasculature and vascular wall thickness while compensating for aperiodic intrinsic motion of a patient during respiration. To overcome the loss of the orthogonality due to uncompensated residual motions and after a lapse of time equal to the trigger delay commenced at the cardiac cycle, the system acquires multiple consecutive time-resolved images of the arterial wall. The cine images are processed offline and a wall thickness measurement is produced.
This technology includes a micro-engineered “thyroid-on-a-chip” that combines human thyroid organoids with integrated micro-vasculature to replicate the gland’s native blood flow and 3-D architecture, enabling rapid, patient-specific drug screening. By permitting real-time perfusion of nutrients, hormones, and immune cells, the platform yields more physiologically relevant data than conventional static cultures or animal surrogates.
