Vocal fold polyps can disrupt vocal fold dynamics and thus can have devastating consequences on a patient's ability to communicate. Three-dimensional flow separation induced by a wall-mounted model polyp and its impact on the wall pressure loading are examined using particle image velocimetry, skin friction line visualization, and wall pressure measurements.

Records range from maintaining information on cage cards to having a detailed database with all of the relevant information on each animal. The primary component of recordkeeping is the individual identification of research animals. There are a variety of methods suitable for identifying mice and rats. This...

University of Notre Dame, IN A fundamental requirement of biomedical research is the proper identification of research animals. It is essential that the right animal is utilized for procedures and data collection. Laboratory mice and rats can be identified with the following permanent methods: ear tags, ear punch codes, microchip implantation, tail tattoos for adult mice, and toe tattoos for neonates. Temporary methods of...

Tree Identification: How To Use a Dichotomous Key

2023
Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University A dichotomous key is a tool that identifies items in nature, such as leaves. This method is based on the idea of choosing between two characteristics. The word dichotomous comes from two Greek words that mean “to divide into two parts.” In a dichotomous key for leaf identification, each pair of phrases describes different features of the leaf. Only one of the phrases correctly applies to the leaf being keyed out. The...

Here, we provide a detailed description of sampling groundwater from a borehole for microplastics analysis using a patented sampling system developed for this purpose. The protocol details the methods for sampling microplastics from boreholes, as well as the separation and chemical identification of microplastics.

Interpretation depends on a combination of visible features rather than a single sign. During assessment, clinicians consider the lesion’s location, size, shape, surface pattern, color, and attachment. These characteristics help organize risk and identify findings that require tissue evaluation. Because visual appearance alone may not establish cellular behavior, characterization guides subsequent diagnostic and management decisions.
Histopathology supplies cellular evidence that visual examination cannot provide. A biopsy or polypectomy specimen is examined for cellular architecture, allowing the lesion to be classified as benign, precancerous, or malignant. This distinction strengthens diagnostic precision and helps determine how the finding should be managed after endoscopic or imaging assessment.
Endoscopy and imaging provide complementary settings for evaluating a polyp. Clinicians can assess location, size, shape, surface pattern, color, and attachment through the selected examination. These observations support initial characterization, while tissue evaluation can clarify cellular behavior when visual findings are insufficient. Using the available assessment together with pathology produces a more complete diagnostic picture.
Assessment begins by documenting the polyp’s location and observable characteristics, including size, shape, surface pattern, color, and attachment. Clinicians then use these findings to classify risk and decide whether tissue should be obtained through biopsy or removal through polypectomy. Histopathological examination of the resulting specimen adds cellular evidence, supporting the diagnostic and management pathway.
Biopsy and polypectomy serve related but distinct roles in evaluation. A biopsy provides tissue for histopathological study, while a polypectomy specimen follows removal of the lesion and can likewise be examined for cellular architecture. In both cases, pathology helps resolve whether the growth is benign, precancerous, or malignant, improving diagnostic precision beyond visual characterization alone.
The findings matter when clinicians must assign risk, determine whether a lesion should be removed, and plan surveillance. Polyp identification is especially relevant to gastrointestinal evaluation, where recognizing potentially precancerous or malignant growths can support earlier cancer detection. Combining lesion characterization with pathology connects diagnosis to decisions about follow-up, monitoring, and patient care.
