This work describes methods to establish acute and chronic hyperglycemia models in zebrafish. The aim is to investigate the impact of hyperglycemia on physiological processes, such as constitutive and injury-induced neurogenesis. The work also highlights the use of zebrafish to follow radiolabeled molecules (here, [18F]-FDG) using PET/CT.

Hyperglycemia

2026
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

Buffer Effectiveness

Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised. The buffer capacity is the amount of acid or base that can be added to a given volume...

Framing Effects

2020
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in different ways based on the...

A major early consequence is a greater osmotic load, meaning excess glucose changes the concentration of dissolved substances in body fluids. This shift promotes water movement and contributes to increased urine production, which can then increase thirst. These symptoms connect a cellular property of elevated glucose with an observable physiological response.
These mechanisms can reinforce one another and progressively impair cell function. Nonenzymatic glycation alters proteins, while oxidative stress damages cellular components and inflammatory signaling disrupts normal tissue responses. Together, they help explain why sustained glucose elevation can produce effects that extend beyond short-term metabolic imbalance.
Blood vessels, nerves, kidneys, and the retina are important sites of damage associated with prolonged glucose elevation. Changes in these tissues help account for complications such as cardiovascular disease, neuropathy, kidney impairment, and retinopathy. Studying tissue-specific effects shows how a systemic metabolic disturbance can produce distinct clinical outcomes.
Glucose-monitoring studies track glucose concentrations in relation to symptoms, disease progression, or responses to treatment. Their results can help researchers examine whether glucose control is associated with fewer harmful consequences and can support efforts to identify prevention strategies. Monitoring therefore links measurable metabolic changes with physiological and clinical outcomes.
Experimental models allow investigators to examine how sustained glucose elevation affects cells, tissues, or whole biological systems under controlled conditions. They support analysis of glycation, oxidative stress, inflammatory signaling, and tissue damage, while also helping researchers evaluate prevention and treatment strategies before interpreting findings in broader biological or clinical contexts.
This topic connects metabolic regulation with changes at cellular, physiological, and clinical levels. It helps explain how disrupted glucose balance can progress from altered osmotic conditions and impaired cell function to vascular, neural, renal, and retinal complications. That framework guides research into disease progression, prevention, glucose monitoring, and treatment.
