Background: There still exists controversy about whether the healthy human middle ear mucosa is sterile or if it may harbor a diverse microbiome. Considering the delicacy of the human round window membrane (RWM), different mechanisms may exist for avoiding inner ear pathogen invasion causing sensorineural deafness. We re-analyzed archival human RWMs using light and transmission electron microscopy after decalcification to determine if bacteria are present in clinically normal human middle ears.

Dodecyl creatine ester (DCE) is a creatine prodrug currently developed for brain diseases, including creatine transporter deficiency (CTD), an incurable rare genetic disease. A dual strategy combining a prodrug to bypass the non-functional creatine transporter and its delivery via the nose-to-brain pathway has been proposed to replenish creatine levels in cerebral cells, particularly in neurons of CTD patients. In vitro and in vivo studies in various animal models, including wild-type non-human primates and creatine transporter deficient mice, show that formulated DCE, when administered intranasally, achieves significant cerebral distribution up to the target cells, the neurons, and modulates the expression of neuronal markers related to cognitive function at doses intended for patients.

Hypertrophic cardiomyopathy (HCM) afflicts humans, cats, pigs, and rhesus macaques. Disease sequelae include congestive heart failure, thromboembolism, and sudden cardiac death (SCD). Sarcomeric mutations explain some human and cat cases, however, the molecular basis in rhesus macaques remains unknown.

Work on the psychology of justice has largely focused on punishment. However, punishment is not our only strategy for dealing with conflict. Rather, emerging work suggests that people often respond to transgressions by compensating victims, involving third-party mediators, and engaging in forgiveness.

Non-human primates (NHPs) are reported as exclusive hosts of Trypanosoma minasense, whose transmission cycle remains unknown. We investigated trypanosomatid infections in 194 NHPs of nine species from the Brazilian Southeast region. We evaluated the impact of landscape composition and forest fragmentation on T.
