Source separation approach for the analysis of spatially resolved multiply excited autofluorescence spectra during optical clearing of skin.

Spatially resolved multiply excited autofluorescence spectroscopy is a valuable optical biopsy technique to investigate skin UV-visible optical properties in clinics. However, it provides bulk fluorescence signals from which the individual endogenous fluorophore contributions need to be disentangled. Skin optical clearing allows for increasing tissue transparency, thus providing access to more accurate in-depth information.

Kankanet: An artificial neural network-based object detection smartphone application and mobile microscope as a point-of-care diagnostic aid for soil-transmitted helminthiases.

Background: Endemic areas for soil-transmitted helminthiases often lack the tools and trained personnel necessary for point-of-care diagnosis. This study pilots the use of smartphone microscopy and an artificial neural network-based (ANN) object detection application named Kankanet to address those two needs.

Methodology/principal Findings: A smartphone was equipped with a USB Video Class (UVC) microscope attachment and Kankanet, which was trained to recognize eggs of Ascaris lumbricoides, Trichuris trichiura, and hookworm using a dataset of 2,078 images.

[Botryoid rhabdomyosarcoma of the urogenital sinus. Apropos of 1 case in an 11 month old child].

Rhabdomyosarcomas are the most common sarcomas of the soft tissues found in children under 15 years. The reported observation is of a vaginal tumour having developed in an eleven-month-year-old little girl. It was a typical botryoid rhabdomyosarcoma, usually found in the hollow organs surrounded on the edges by mucus.

Dispersal by Propithecus verreauxi at Beza Mahafaly, Madagascar: 1984-1991.

From 1984 to 1991, 126 males and females were marked and monitored in a wild population of Propithecus verreauxi in southwest Madagascar. Animals were assigned birth years, based on known birth date or degree of dental wear calibrated by recapture data. Twenty-one of 27 groups identified in 1984 persisted within stable home range boundaries, 6 groups disappeared, and 6 new groups formed.
