The effect of delta-9 tetrahydrocannabinol and methamphetamine on sustained attention in the jumping spider (Trite planiceps).

Decreasing responsiveness to repeated visual stimuli (i.e., the inability to sustain attention) in jumping spiders (Salticidae) parallels that found in humans.

Multi-modal analysis reveals tumor and immune features distinguishing EBV-positive and EBV-negative post-transplant lymphoproliferative disorders.

The oncogenic Epstein-Barr virus (EBV) can drive tumorigenesis with disrupted host immunity, causing malignancies including post-transplant lymphoproliferative disorders (PTLDs). PTLD can also arise in the absence of EBV, but the biological differences underlying EBV(+) and EBV(-) B cell PTLD and the associated host-EBV-tumor interactions remain poorly understood. Here, we reveal the core differences between EBV(+) and EBV(-) PTLD, characterized by increased expression of genes related to immune processes or DNA interactions, respectively, and the augmented ability of EBV(+) PTLD B cells to modulate the tumor microenvironment through elaboration of monocyte-attracting cytokines/chemokines.

Pericytes require physiological oxygen tension to maintain phenotypic fidelity.

Pericytes function to maintain tissue homeostasis by regulating capillary blood flow and maintaining endothelial barrier function. Pericyte dysfunction is associated with various pathologies and has recently been found to aid cancer progression. Despite having critical functions in health and disease, pericytes remain an understudied population due to a lack of model systems which accurately reflect in vivo biology.

Impact of Treatment of Pudendal Neuralgia on Pain: A Systematic Review and Meta-Analysis.

Introduction And Hypothesis: Pudendal neuralgia is chronic pelvic pain associated with the pudendal nerve. Unfortunately, the best treatment approach is unknown. Our objective was to systematically assess interventions for pudendal neuralgia for improvement in pain.
