Multimodal imaging monitoring of key physiological changes of peripheral arterial disease
… Within this platform, we will highlight critical physiological events that we term “landmarks.” To define these landmarks, we use a multimodal imaging approach starting with Laser Speckle Contrast Imaging (LSCI) and Power Doppler ultrasound for perfusion (superficial and deep tissue, …

The physiological changes of circulatory death with respect to organ donation
… in the donor prior to death, suggests that changes in donor physiology during the agonal phase, together with the subsequent period of warm ischaemia, may be responsible for the differences seen in organ function. Although donated organs and warm ischaemia have been extensively studied, the …

Vegetative storage protein accumulation and physiological changes occurring within interior spruce seedlings
… P.engelmanni complex) was evaluated along with changes in seedling physiology. The 30 kD and 27 kD vegetative storage proteins (VSP) appeared after vegetative maturity (budset) and accumulated during the development of rest and the acquisition of cold hardiness. This trend was observed in bud …

Exploiting physiological changes during the flow experience for assessing virtual-reality game design.
… on earlier work to evaluate flow dynamics from a physiological perspective using a custom video game. Although advancements in this area are growing, there has been little consideration given to the interpersonal characteristics that may influence the expression of the flow experience. In this …

Effects of heat-stress-induced physiological changes on the productivity of dairy cattle
Dairy cattle exposed to summer heat stress (HS) typically exhibit altered metabolic characteristics, including hyperinsulinemia concurrent with hypoglycemia. The reasons for this change in glycemic status and its consequences are currently unknown. This project aimed to examine the relationship …

New Types of Morpho-Physiological Changes in Cells Exposed to Nanosecond Pulsed Electric Field
… they can be inferred from morpho-physiologic changes, or cell reshaping, that accompany nsPEF exposure. During the exposure cells undergo reshaping that is manifested in swelling and diffuse blebbing. Recently we identified two new distinct forms of reshaping, pseudopod-like blebbing and …

Biochemical and physiological changes in bovine sperm during extended incubation under aerobic and anaerobic conditions
… was undertaken to determine the biochemical and physiological changes occurring in sperm during extended incubations (storage) under conditions of either complete exclusion of oxygen from the diluent, reduced oxygen tension, normal atmospheric conditions or elevated exposure to reactive oxygen …

Investigation and Application of Methods for Measuring Energy Expenditure Rate and Selected Physiological Changes Due to Exercise in Horses
… three major objectives: (1) to evaluate certain physiological parameters adapted from studies on human athletes in measuring selected physiological changes due to exercise in horses, (2) to accurately determine and factor the energy expenditure rate during physical work in horses, and (3) to …

Distribution of hydrocarbons in a salt marsh ecosystem after an oil spill and physiological changes in marsh animals from the polluted environment
… of the oil in the marsh ecosystem, 3) on changes in chemical composition of the oil with time due to physical and chemical weathering processes and biochemical degradation of hydrocarbons, 4) on the effects of oiled sediments on the population distribution, behavior, and survival of the …

INVESTIGATION OF ACUTE STRESS IMPACT ON NURSERY PIG GASTROINTESTINAL FUNCTION AND ABILITY OF BIOACTIVE COMPONENTS OF GARLIC TO MITIGATE STRESS-INDUCED PHYSIOLOGICAL CHANGES
Experiments were conducted to determine the effect of post-weaning feed and water deprivation on nursery pig growth performance, gastrointestinal function, and ability of garlic-derived diallyl disulfide (DADS) and diallyl trisulfide (DATS) to mitigate deprivation-induced effects. For the first …

Computer simulation of the osteocyte and bone lining cell network and the effect of normal physiological changes in cellular functions on that network
Osteocytes play a critical role in the regulation of bone remodelling by translating strain due to mechanical loading into biochemical signals transmitted through the interconnecting lacuno-canalicular network to bone lining cells (BLCs) on the bone surface. This work aims to examine the effects of …

Physiological Changes Occurring in the Cellular Membranes of Clostridium Acetobutylicum ATCC 824 and a Butanol-Tolerant Mutant During the Acetone-Butanol-Ethanol Fermentation
The acetone-butanol-ethanol fermentation by Clostridium acetobutylicum is not able to compete economically with the petroleum methods, due to the premature termination of this fermentation from the butanol produced by the cell. It is known that alcohols disrupt the membrane structure and function, …

An Examination of Two Possible Delineations of the REMS-Consolidation Hypothesis.
… stages is readily identifiable due to concurrent physiological changes: elevated temperature, increased metabolic rates, electrical brain patterns similar to those in the arousal state, and rapid eye movements. This stage has been termed "rapid eye movement sleep" (REMS), or "paradoxical sleep" …

Fungal Pathogens Associated With Seasonal Dormancy of Zoysia Japonica: The Behavior and Interaction of Gaeumannomyces Incrustans and Rhizoctonia Solani, Coinhabitants
… Few studies have examined the morphological and physiological changes undergone by warm-season turfgrasses during this transitional period. Sprigs of Z. japonica were dissected by plant material (root, shoot, and rhizome) and examined under various temperature regimes, both static and …

Methods for Physiologic Tremor Characterization, Mitigation, and Modeling
… the combined mechanical, electrical, and physiological changes in the body render it a challenging phenomenon to study. Advancements in physiological monitoring have allowed researchers to characterize tremors. Accelerometry and surface electromyography are often used to measure tremor …

Behavioral change in response to low-grade non-infectious stimuli: findings and potential neuroimmune mechanisms
… dismissed as an unavoidable consequence of the physiological changes resulting from pathogen-dependent immune activation, it is now well known that sickness behavior is a consequence of neuroimmune activation. Neuroimmunity serves as a bridge between the peripheral immune system and the central …
