Towards algorithm auditing: managing legal, ethical and technological risks of AI, ML and associated algorithms.

-Business reliance on algorithms is becoming ubiquitous, and companies are increasingly concerned about their algorithms causing major financial or reputational damage. High-profile cases include Google's AI algorithm for photo classification mistakenly labelling a black couple as gorillas in 2015 (Gebru 2020 In , pp. 251-269), Microsoft's AI chatbot Tay that spread racist, sexist and antisemitic speech on Twitter (now X) (Wolf .

A Novel Method to Estimate Levels of Receptors Using an Allosteric Modulator: Focus on Muscarinic M1 Receptor.

This chapter outlines some of the general principles that need to be considered when developing a radioligand binding assay to measure the affinity and density of radioligand binding to a receptor in tissue or on cells. In addition it describes an innovative step forward in using radioligand binding assays to measure levels of muscarinic M1 receptors in human postmortem CNS, using both membrane binding and in situ radioligand binding. These examples show how, using receptor-specific allosteric modulators, it is possible to gain an estimate of the density of a single receptor using a radioligand that is not totally specific to the target site of interest.

Altered levels of dopamine transporter in the frontal pole and the striatum in mood disorders: A postmortem study.

Dopamine dysregulation is known to play a major role in the pathophysiology of major depressive disorders (MDD) and bipolar disorders (BD). The dopamine transporter (DAT) plays a critical role in regulating dopamine concentration at the synaptic cleft and therefore could have an important role in the molecular pathology of MDD and BD. To test this hypothesis, we measured levels of [H]mazindol binding to DAT in Brodmann's area (BA) 10, BA 17 as well as in the dorsal and ventral striatum from 15 controls, 15 patients with MDD and 15 patients with BD, obtained postmortem, using in situ radioligand binding with autoradiography.

Successful Closed Reduction of Distal Radius Volar Locking Plate Plastic Deformation with Associated Fracture: A Case Report.

Case: Distal radius fractures are among the most common orthopaedic injuries. The volar locking plate is now the most utilized internal fixation method for these fractures. There are few reports of mechanical failure of volar locking plates within the literature.
