Despite a large body of evidence globally demonstrating that the criminalization of sex workers increases HIV/STI risks, we know far less about the impact of criminalization and policing of managers and in-call establishments on HIV/STI prevention among sex workers, and even less so among migrant sex workers.

A concise insight into the outputs provided by the latest prototype of visible-near infrared (VIS-NIR) multispectral scanner (National Research Council-National Institute of Optics, CNR-INO, Italy) is presented. The analytical data acquired on an oil painting Madonna of the Rabbit by É. Manet are described. In this work, the VIS-NIR data were complemented with X-ray fluorescence (XRF) mapping for the chemical and spatial characterization of several pigments. The spatially registered VIS-NIR data facilitated their processing with spectral correlation mapping (SCM) and artificial neural network (ANN) algorithm respectively for pigment mapping and improved visibility of pentimenti and of underdrawing style. The data provided several key elements for the comparison with a homonymous original work by Titian studied within the ARCHive LABoratory (ARCHLAB) transnational access project.

Alcohol use is pervasive among female sex workers (FSW) placing them at increased risk of violence and sexual risk behaviors. FSW often live and work where alcohol is highly normative.

Ovarian neoplasms are a heterogeneous group of tumors including surface epithelial, germ cell and sex cord stromal tumors with a subset having low malignant potential (borderline tumors). While the surgical management plan differs in different categories of tumors, preoperative diagnosis is seldom available. In these circumstances, the role of frozen section becomes invaluable. In the current study, we aimed to evaluate the accuracy of the frozen section of ovarian tumors in our setup.

The authors present an image of the Madonna and Child painted by one of the less well-known Italian artists of the Renaissance. The appearance of the child in this work raises the question of whether his obvious physical deformities were deliberately portrayed as an empathic gesture toward children with disabilities. Various retrospective diagnoses of the child’s condition are enumerated, one of which is considered more probable.

Stereotyped movement of paired pectoral fins in zebrafish larvae could be considered a simple model with which to investigate the neural basis of behavior. Using a high-speed camera, we explored the repertoire of pectoral fin movements by naturally behaving larvae at 5-6 days post-fertilization. Previously, two types of fin movements were characterized in association with locomotion: ‘CRAWLing,’ an alternating fin movement associated with slow swimming, and ‘TUCKing,’ the adduction of both fins associated with fast swimming. We here describe a third mode of fin movement, which we call ‘Munch’s SCREAM’, in which both pectoral fins were flipped anteriorly so that they reached the skin on the sides of the head, thus covering the otic vesicles. This behavior occurred spontaneously and was often associated with a slight regression or a sudden bending and change in body orientation. It could be also induced effectively in the agarose-embeded larvae by tactile stimulation on the skin around the eye and nose, some of which are associated with struggling, in which waves of bending propagate from the tail to the head. Larvae can still CRAWL and perform the SCREAM even when their forebrain and midbrain have been removed, suggesting that the neural circuits involved in the SCREAM are present in the hindbrain and/or spinal cord.
