We describe here a behavioral setup and data analysis method for assaying olfactory responses of up to 100 vinegar flies (Drosophila melanogaster). This system may be used with single or multiple olfactory stimuli, and adaptable for optogenetic activation or silencing of neuronal subsets.

Abdominal Regions and Quadrants
0 Views •
2025
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity. The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...

Collection, Isolation and Enrichment of Naturally Occurring Magnetotactic Bacteria from the Environment

We demonstrate a method to collect magnetotactic bacteria (MTB) that can be applied to natural waters. MTB can be isolated and enriched from sediment samples using a relatively simple setup that takes advantage of the bacteria's natural magnetism. Isolated MTB can then be examined in detail using both light and electron microscopy.

Using a Hemacytometer to Count Cells
0 Views •
2023
Many biomedical experiments require manipulation of a known quantity of cells, in order to achieve accurate, reproducible, and statistically-relevant data. Therefore, learning how to count cells is a particularly essential technique for any successful biomedical scientist. The most common way to count cells is by using a hemacytometer - an instrument that bears two laser-etched grids, which aid in the enumeration of an aliquot cells under a simple light microscope. This data can then be used to...

Abdominal Exam IV: Acute Abdominal Pain Assessment
0 Views •
2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...
FAQs
It provides a consistent spatial reference for relating localized findings to nearby structures. Pain or other abnormalities in this region can be considered alongside the cecum, appendix, terminal ileum, right ureter, and, in females, the right ovary and uterine tube. This anatomical matching helps organize biological and clinical interpretation without treating location alone as a diagnosis.
The region contains structures from the digestive, urinary, and reproductive systems, so more than one organ system can contribute to a local finding. Inflammation, obstruction, infection, or tissue injury affecting these structures may produce localized pain. Recognizing this shared anatomical area prevents interpretation from focusing on only one system before the relevant structures are considered.
In females, the right ovary and uterine tube add reproductive structures to the possible anatomical sources of a finding. The cecum, appendix, terminal ileum, and right ureter remain relevant, but the additional pelvic anatomy broadens the structures considered during assessment. This distinction helps biology-based interpretation account for differences in the organs present within the region.
Inflammation, obstruction, infection, and tissue injury are the major processes identified in the source material as causes of localized pain there. These mechanisms can affect structures from different systems, including intestinal, urinary, or reproductive anatomy. The clinical significance of the pain therefore depends on relating the symptom to the specific structure and process involved.
Clinicians use the region as an anatomical reference when assessing localized abdominal findings. They relate the reported or observed location to structures positioned there, then consider whether the pattern could involve the cecum, appendix, terminal ileum, right ureter, or female reproductive organs. This approach supports assessment of appendicitis and intestinal disorders without relying on location in isolation.
Assessment can help evaluate conditions in which inflammation, obstruction, infection, or tissue injury affects nearby anatomy. The source specifically identifies appendicitis and intestinal disorders as relevant examples. Because the region includes digestive, urinary, and reproductive structures, its examination also helps organize the broader anatomical context in which localized symptoms are interpreted.
