Spatial and temporal influences on the physiological condition of invasive silver carp
… that provide insights into the health and condition of free-swimming fish sampled across different habitats. My results suggested that silver carp nutrition varied across rivers and time periods, stress varied across time periods, and there were few effects of abiotic and biotic factors on …

Life history trade-offs in a parental care-providing fish: the role of reproductive value, predation threat, and physiological condition on brood abandonment decisions by paternal largemouth bass
… to maximize reproductive success at a cost to physiological and nutritional condition of the care-providing individual, and at a cost to future reproductive potential. Parental investment decisions are rooted in tradeoffs between these factors, and when the cost of care-provision is outweighed …

Computational analysis on stent geometries in carotid artery
… were 3-D modelled and simulated in different physiological conditions; normal blood pressure (NBP), pre-hypertension (PH) and hypertension stage one (HS1) through computational fluid dynamic (CFD) method. The haemodynamic performance of stent was analysed based on parameters namely time …

The role of fish physiology, behaviour, and water discharge on the attraction and passage of adult sockeye salmon (Oncorhynchus nerka) at the Seton River dam fishway, British Columbia
… with minimal delay, energy expenditure, and physiological stress. The research presented here is based on investigations into fishway attraction and passage for the Gates Creek sockeye salmon (Oncorhynchus nerka, Walbaum) stock at the Seton River dam in British Columbia. The first part of …

Nutritional condition and stress response of fishes along a gradient of habitat quality in the St. Lawrence River: physiological consequences of anthropogenic habitat degradation
… underlying variation in organismal health and condition, such individual-level metrics are rarely evaluated in the context of ecosystem disturbance. Using physiological sampling, we can examine the effects of land use on the health of resident fishes, and improve our understanding of the …

Influence of resource availability on lifehistory traits in coral-feeding butterflyfishes (Pisces: Chaetodontidae)
… is likely to have significant effects on the physiological condition and subsequent fitness of resident fishes, if not their absolute abundance. The first component of this study compared the abundance, feeding, and condition of two species of coral-feeding butterflyfishes (Chaetodon baronessa …

FABRICATION OF POLYMER NANOFLUIDIC CHIPS WITH PROTON BEAM WRITING AND NANOIMPRINTING FOR DNA LINEARIZATION
… and cooling systems and optimized bonding conditions. Nano ridges patterns are transferred from resist master mold to rigid stamps and polymer substrate with high fidelity and minimal distortion. This replication method is compared with PDMS and X-PDMS casting on its merits. PMMA chips are …

Chemical functionalization of AFM cantilevers
… such as in water or various buffers from which physiological condition can be maintained, the scope of the application of this imaging technique has been expanded to soft biological materials. In addition, the main usage of AFM has been to image the material and provide the shape of surface, …

Preliminary studies of boxwood blight
… thoae plants that have been weakened by some physiological condition such as lack of moisture, winter injury, malnutrition, insect injury, or improper transplanting.

Tvorba proteinových granulí v diferencovaných buňkách kvasinkových kolonií
… formation of protein granules is related to the physiological state of the cell (e.g. chronological and replicative aging), but also to changing environmental conditions and to cellular responses to stress factors. A relatively large fraction of proteins relocalizes to some type of protein …

Methodologies and analysis of metabolic flux in mammalian systems
… and lactate contribution to TCA cycle under physiological condition, which confirms the conventional knowledge that glucose is the main direct energy source in body. Taken together the new MFA methodology will offer unprecedented opportunities for expanding research in metabolic …

Investigations of Serotonin Metabolism in Mammalian and Other Deuterostome Model Systems
… were also investigated in this mammal under conditions of induced serotonin syndrome, a physiological condition caused by an excessive increase in 5-HT levels often associated with a combination of antidepressant therapies. This research contributes to our understanding of the metabolic …

Brain and Cognitive Consequences of Early-Life Immune System Challenge in a Songbird
… is a trait that is sensitive to developmental conditions. Existing research supports the idea that the ability to develop and maintain cognitive abilities depends on the physiological condition of the individual, which can be influenced by the early environment. Alterations in maternal care, …

Understanding Obstructive Sleep Apnea in Menopausal Women: Evidence, Gaps, and Lived Experiences
… has long been viewed as a predominantly male condition; however, the risk of OSA increases significantly during menopause due to hormonal and physiological changes that influence airway stability, ventilatory control, and sleep quality. Despite this increased vulnerability, OSA in menopausal …

Influence of body condition and homo- vs. heterosubtypic immunity on influenza A virus infection in mallard ducks : experimental infection data
… have not represented the natural variation in physiological condition observed in migrating waterfowl and have only used captive-bred birds. We assessed how body condition affects susceptibility, viral shedding, and antibody production in wild-caught and captive-bred juvenile mallards …

Physiological Factors Affecting the Bactericidal Activity of the Western Fence Lizard (Sceloporus occidentalis) for the Lyme Disease Spirochete, Borrelia burgdorferi
… 2 we tested the hypothesis that host lizard physiological condition impacts their borreliacidal capacity. Blood plasma of lizards in varying physiological conditions was challenged against cultured <em>B. burgdorferi</em>, and the complement-mediated inactivation of spirochetes was …

Non-invasive optical methodologies to evaluate and enhance Chlorella vulgaris biomass
… tool for monitoring biomass growth and physiological condition is presented. Biomass qualities, such as pigment content, were quantified and the spectra for cultures recorded, allowing for machine learning to create linear relationships between the two elements. From this, predictions …

Design principles of mammalian signaling networks : emergent properties at modular and global scales
… scaffold may regulate signaling under different physiological condition. Our studies identify regulatory properties of scaffold proteins that allow them to both amplify and attenuate incoming signals in different biological contexts. In a further, supplementary study, simulations also indicate …

Determining the Usefulness of Aerobic and Anaerobic Enzyme Assays as Proxies for Rockfish Ecological Data.
… is a work in progress. In particular, changes in physiological condition aver the course of the year is poorly described. This study examined 19 different species of Sebastes from the Southern California Bight over four seasons (late summer, fall, winter, and spring) using metabolic enzyme assays. …
