Twenty years ago, I arrived in Puerto Rico from New York City to establish a neuroscience laboratory and research program on extinction of conditioned fear. The lab's first research paper appeared in the (Quirk et al., 2000) and has been cited >900 times. The success of this project in Puerto Rico far surpassed my original expectations. Therefore, I thought it might be useful to identify the factors responsible for this success, with the hope of facilitating the development of laboratories in diverse settings. A description of our lab practices is interspersed with personal statements from trainees hailing from Puerto Rico and other parts of Latin America. Creating an effective research and training environment depends less on the director's personality and more on the proper practice of activities that foster intellectual growth, such as journal clubs, lab meetings, and philosophy of science retreats. On a personal level, this project has been enormously gratifying. The unique environment in Puerto Rico fostered my best work, and I am very happy to have established my laboratory here.

Cochrane Rehabilitation and the World Health Organization (WHO) Rehabilitation Program are collaborating to produce four Cochrane overviews of systematic reviews that synthesize the current evidence from health policy and systems research (HPSR) in rehabilitation. They will focus on the four pillars of HPSR identified by the Cochrane Effective Practice and Organization of Care (EPOC) taxonomy: delivery arrangements, financial arrangements, governance arrangements, and implementation strategies. The protocol describes why HPSR is currently needed in rehabilitation, provides detailed information on the four EPOC pillars in interaction with rehabilitation and reports the Cochrane methods that will be followed to produce the overviews.

Matrix-bound vesicles (MBVs), an integral part of the extracellular matrix (ECM), are emerging as pivotal factors in ECM-driven molecular signaling. This study is the first to report the isolation of MBVs from porcine arterial endothelial cell basement membranes (A-MBVs) and thyroid cartilage (C-MBVs), the latter serving as a negative control due to its minimal vascular characteristics. Using Transmission Electron Microscopy (TEM), Nano-Tracking Analysis (NTA), Electrochemical Impedance Spectroscopy (EIS), and Atomic Force Microscopy (AFM), we orthogonally characterized the isolated MBVs.

Hearing loss has historically been mainly associated with elevated pure-tone thresholds. However, in recent years, there has been increased interest in addressing the hearing difficulties reported by individuals with normal hearing thresholds. In this study, we measured hearing thresholds, noise history, temporary threshold shift history, and hearing difficulty for a sample of 10,492 Service Members.

Many alpine ecosystems are undergoing vegetation degradation because of global changes, which are affecting ecosystem functioning and biodiversity. The ecological consequences of alpine pioneer community degradation have been less studied than glacial retreat or meadow degradation in alpine ecosystems. We document the comprehensive responses of microbial community characteristics to degradation processes using field-based sampling, conduct soil microcosm experiments to simulate the effects of global change on microorganisms, and explore their relationships to ecosystem functioning across stages of alpine pioneer community degradation.

Background/objectives: Cocaine use disorder is an intersecting issue in populations with HIV-1, further exacerbating the clinical course of the disease and contributing to neurotoxicity and neuroinflammation. Cocaine and HIV neurotoxins play roles in neuronal damage during neuroHIV progression by disrupting glutamate homeostasis in the brain. Even with combined antiretroviral therapy (cART), HIV-1 Nef, an early viral protein expressed in approximately 1% of infected astrocytes, remains a key neurotoxin.
