Phase Contrast and Differential Interference Contrast Microscopy01:26

Phase Contrast and Differential Interference Contrast Microscopy

15.3K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Endoscopic Procedures II: Colonoscopy

1.2K
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Group Polarization01:01

Group Polarization

39.4K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

22.2K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.1K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Polarity of the Cytoskeleton01:18

Polarity of the Cytoskeleton

25.7K
The intrinsic polarity of cells can be primarily attributed to two factors- i) the asymmetric accumulation of mobile components such are regulatory molecules and subcellular components across the cell and ii) the orientation of polar cytoskeletal filaments that make up the cytoskeletal networks, specifically microfilaments, and microtubules arranged along the axis of polarity. Interactions between the cytoskeletal filaments are crucial for the establishment and maintenance of the polar nature...

Summary

Polarized light colposcopy did not offer significant benefits over standard colposcopy for evaluating abnormal cervical cytology. Further research is needed to establish its clinical utility in colposcopy examinations.

Area of Science:

  • Gynecology
  • Medical Imaging

Background:

  • Abnormal cervical cytology requires accurate colposcopy for diagnosis.
  • Conventional colposcopy is the standard for evaluating cervical lesions.

Purpose of the Study:

  • To compare the effectiveness of polarized light colposcopy versus standard colposcopy.
  • To evaluate benefits in women with abnormal cervical cytology.

Main Methods:

  • 330 subjects underwent both polarized and standard colposcopy.
  • Sensitivity, specificity, ROC analysis, and agreement statistics were used.
  • Differences in biopsy numbers and lesion severity were assessed.

Main Results:

  • Polarized light colposcopy showed no significant improvement in sensitivity, specificity, or ROC analysis compared to standard colposcopy.
  • Agreement between colposcopy impression and histopathology was high for both methods.
  • No significant differences were found in the number of lesions or biopsy sites.

Conclusions:

  • Polarized light colposcopy did not demonstrate utility as an adjunct to conventional colposcopy in this study.
  • Additional research is necessary to determine the clinical value of polarized light colposcopy.
