Background: Trans people in prison experience disproportionate rates of harm, including negative mental health outcomes, and thus require special protections. Instead, corrections policies have historically further marginalised them. This critical policy review aimed to compare corrections policies for trans people in Australia and New Zealand with human rights standards and consider their mental health impact.

To assess linkages of patient data from a health care system in the southeastern United States to microdata from the American Community Survey (ACS) with the goal of better understanding health disparities and social determinants of health in the population. Once a data use agreement was in place, a stratified random sample of approximately 200 000 was drawn of patients aged 25 to 74 years with at least 2 visits between January 1, 2016, and December 31, 2019. Information from the sampled electronic health records (EHRs) was transferred securely to the Census Bureau, put through the Census Person Identification Validation System to assign Protected Identification Keys (PIKs) as unique identifiers wherever possible.

The evolution of gene fusions that result in covalently linked protein domains is widespread in bacteria, where spatially coupling domain functionalities can have functional advantages in vivo. Fusions to integral membrane proteins are less widely studied but could provide routes to enhance membrane function in synthetic biology. We studied the major facilitator superfamily (MFS), as the largest family of transporter proteins in bacteria, to examine the extent and nature of fusions to these proteins.

Fear conditioning in the rat typically involves pairing a conditioned stimulus (tone) with an aversive unconditioned stimulus (foot shock) which elicits a freeze response. Although the circuitry that underlies this form of learning is well defined, potential synaptic changes associated with this form of learning have not been fully investigated. This experiment examined synaptic structural plasticity in the lateral amygdala which is critical for the acquisition of the conditioned fear response.

Psychophysical performance was measured in a number of different tasks in order to compare performance under different masking conditions. With the noise masker set to provide a given amount of masking, frequency discrimination of a 4-kHz tone was shown to be worse in a lowpass noise than in a wideband noise. Discrimination of the intensity of the tone under these two masking conditions was comparable except at the lowest level of tone.
