This article describes a new method to study mouse voiding behavior by incorporating video monitoring in the conventional void spot assay. This approach provides temporal, spatial, and volumetric information on the voiding events and details of mouse behavior during the light and dark phases of the day.

Total Voids in Concrete

2024
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement ratio...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Frequency-dependent Selection

2026
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...

2015
This protocol describes the application of high-frequency ultrasound (HFUS) for imaging mouse cervical lymph nodes. This technique optimizes visualization and quantification of cervical lymph node morphology, volume and blood flow. Image-guided biopsy of cervical lymph nodes and processing of lymph tissue for histological evaluation is also demonstrated.
FAQs
An increased pattern can arise through two broad pathways: the bladder may hold less urine before signaling the need to void, or the body may produce more urine than usual. Distinguishing reduced storage from increased output matters because the same observed frequency can reflect different lower urinary tract or systemic patterns.
Bladder capacity alone does not determine the pattern. Filling, sensory signaling, and voluntary control of the urethral sphincter operate together: sensations influence when a person decides to void, while sphincter control affects whether urination can be postponed. Considering these components helps clinicians interpret frequency as a functional pattern rather than an isolated count.
Frequency becomes more informative when paired with urgency, nocturia, fluid intake, and urine volume. Frequent daytime voiding with one pattern of urine production may suggest a different explanation from frequent voiding accompanied by increased output or nighttime episodes. This combined assessment prevents a single symptom from being interpreted without its relevant context.
A voiding diary organizes observations over a defined period so the pattern can be reviewed rather than recalled informally. Relevant entries include urination, fluid intake, urgency, nocturia, and urine volume. Comparing these records allows clinicians to relate frequency to filling and output patterns, supporting a more focused clinical assessment.
Clinicians can use frequency records at several stages: to support diagnostic assessment, guide treatment planning, and evaluate response to therapy. Repeating the record after an intervention provides a way to compare patterns over time. The value lies not only in whether frequency changes, but also in whether associated urgency, nocturia, intake, or volume changes with it.
Patterns of increased voiding frequency may occur with urinary tract infection, diabetes, medication effects, or bladder dysfunction. Frequency alone does not identify which context is present, so clinicians interpret it alongside urine volume, fluid intake, urgency, and nocturia. This broader comparison helps connect a lower urinary tract symptom with the medical circumstances surrounding it.
