AI Article Synopsis
- Dermoscopy has a long history dating back to 1663 and was primarily used for diagnosing skin lesions until 1971.
- The study involved 68 patients, where two dermatologists assessed pigmented skin lesions using both simple observation and dermoscopy, with results compared to histological (biopsy) findings.
- The results indicated that dermoscopy had a higher agreement with histology in diagnosing malignancy, showing better sensitivity and specificity than simple observation, making it a more effective non-invasive diagnostic tool.
Article Abstract
Introduction: Dermoscopy began in 1663, and until 1971 was used to diagnose skin lesions.
Objective: To measure the correlation between simple observation and dermoscopy to diagnose pigmented skin lesions.
Methods: The study was conducted in Centro Médico Nacional La Raza. Sixty-eight patients with pigmented skin lesions were included. Participants were randomly examined by two dermatologists blinded to the study. Both dermatologists did simple observations and dermoscopy. Every participant was diagnosed using both procedures and by both doctors. A skin biopsy was obtained for pathological study.
Results: Kappa index of agreement to diagnose malignancy of the skin lesion between simple observation and histology was 0.69 (95 % CI 0.44, 0.93); the dermoscopy/histology Kappa index was 0.73 (95 % CI 0.60, 0.87). 75 % of positive results were obtained by using dermoscopy, compared to 63.9 % obtained by simple observation (p = 0.12). Simple observation and dermoscopy showed 94.44 % and 90.38 % sensitivity, specificity was 73.33 and 82.92 % and test accuracy was 84.84 and 87.09 % respectively.
Conclusions: Dermoscopy is a non-invasive technique with acceptable specificity and superior than simple observation to diagnose pigmented skin lesions.

Nyquist Ghost Elimination for Diffusion MRI by Dual-polarity Readout at Low b-values.

Dual-polarity readout is a simple and robust way to mitigate Nyquist ghosting in diffusion-weighted echo-planar imaging but imposes doubled scan time. We here propose how dual-polarity readout can be implemented with little or no increase in scan time by exploiting an observed b-value dependence and signal averaging. The b-value dependence was confirmed in healthy volunteers with distinct ghosting at low b-values but of negligible magnitude at b = 1000 s/mm2.

The extrusion bioprinting of collagen material has many applications relevant to tissue engineering and regenerative medicine. Freeform Reversible Embedding of Suspended Hydrogels (FRESH) technology is capable of 3D printing collagen material with the specifications and details needed for precise tissue guidance, a crucial requirement for effective tissue repair. While FRESH has shown repeated success and reliability for extrusion printing, the mechanical properties of completed collagen prints can be improved further by post-print crosslinking methodologies.

Ignition of the lubricating fluid in a mechanical system is a highly undesirable and unsafe condition that can arise from the elevated temperatures and pressures to which the lubricant is subjected. It is therefore important to understand the fundamental chemistry behind its ignition to predict and prevent this condition. Lubricating oils, particularly those with a mineral oil base, are very complex mixtures of thousands of hydrocarbons.

Background: Colonoscopy is the standard diagnostic method for colorectal cancer. Patients usually receive written and verbal instructions for bowel preparation (BP) before the procedure. Failure to understand the importance of BP can lead to inadequate BP in 25%-30% of patients.
