As we assess the habitability of other worlds, we are limited by being able to only study terrestrial life adapted to terrestrial conditions. The environments found on Earth, though tremendously diverse, do not approach the multitude of potentially habitable environments beyond Earth, and so limited terrestrial adaptive capabilities tell us little about the fundamental biochemical boundaries of life. One approach to this problem is to use experimental laboratory evolution to adapt microbes to these novel environmental conditions.

Lung fibrosis development utilizes alveolar macrophages, with mechanisms that are incompletely understood. Here, we fate map connective tissue during mouse lung fibrosis and observe disassembly and transfer of connective tissue macromolecules from pleuro-alveolar junctions (PAJs) into deep lung tissue, to activate fibroblasts and fibrosis. Disassembly and transfer of PAJ macromolecules into deep lung tissue occurs by alveolar macrophages, activating cysteine-type proteolysis on pleural mesothelium.

Objectives: Cerebral microbleeds (cMBs) are common imaging findings in conditions related to cerebral amyloid angiopathy (CAA). Blood-brain barrier (BBB) leakage is considered pivotal in their pathogenesis. This study investigates the potential role of cerebral microenhancement (cME) as an imaging biomarker on 3D T1 black-blood MRI (BB-MRI) for BBB rupture, predicting the formation of cMBs in inflammatory CAA variants.

The topic of data storage, traceability, and data use and reuse in the years following experiments is becoming an important topic in Europe and across the world. Many scientific communities are striving to create open data by the FAIR principles. This is a requirement from the European Commission for EU-funded projects and experiments at EU-funded research infrastructures (RIs) and from many national funding agencies.

Introduction: Primary care providers or clinicians (PCPs) have the potential to assist dermatologists in screening patients at risk for skin cancer, but require training to appropriately identify higher-risk patients, perform skin checks, recognize and biopsy concerning lesions, interpret pathology results, document the exam, and bill for the service. Very few validated dermatology training programs exist for PCPs and those that are available focus primarily on one emphasis area, which results in variable efficacy and single-topic limited scope.

Methods: We have created a free, online, continuing education program (Melanoma Toolkit for Early Detection, MTED) that allows learners to choose from a variety of multimedia tools (image recognition, videos, written material, in-person seminars, self-tests, etc.

Cognitive, Linguistic & Psychological Sciences, Brown University, Providence, RI,

We agree with Sijilmassi et al. that historical myths are a tool for coalition recruitment. We argue, however, that a close fit between an evolved entity and an identified function does not imply that the latter is the critical evolutionary trigger.

The retrograde approach to chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly contributed to the success rates of CTO PCI. It is usually performed in complex CTO lesions, in which the antegrade approach is not feasible or fails. In this article we discuss the steps to perform retrograde CTO PCI and its complications and success rates.

Butler Hospital and the Department of Psychiatry & Human Behavior, Brown University, 345 Blackstone Boulevard, Suite 2, Providence, RI 02906, United States of America. Electronic address:

Purpose: To develop and evaluate the effectiveness of an asynchronously delivered app, InBloom, for postpartum depression (PPD) prevention relative to an evidence-based synchronously delivered in-person intervention, ROSE (Reach Out, Stay Strong, Essentials for mothers of newborns) for depression and return on investment via a prospective randomized controlled trial and quasi-experimental cohort analyses.

Background: PPD affects 1 in 7 gestational parents in the US, causing emotional distress, consequences for infant development and child adjustment, disruptions in family relationships, and financial burden. ROSE is an evidence-based intervention administered as four in-person group sessions plus one postpartum booster session.

Background: There are no clinical parameters that predict response to intra-arterial chemotherapy (IAC), which is a first-line treatment for primary and recurrent unilateral retinoblastoma. We evaluated the utility of ophthalmic ultrasound with color Doppler imaging to predict retinoblastoma response to IAC treatment.

Methods: The medical records of 14 retinoblastoma patients (20 eyes) treated with IAC were reviewed retrospectively.

Aims: Excellent outcomes have been reported following CT-based robotic arm-assisted total hip arthroplasty (rTHA) compared with manual THA; however, its superiority over CT-based navigation THA (nTHA) remains unclear. This study aimed to determine whether a CT-based robotic arm-assisted system helps surgeons perform accurate cup placement, minimizes leg length, and offsets discrepancies more than a CT-based navigation system.

Methods: We studied 60 hips from 54 patients who underwent rTHA between April 2021 and August 2023, and 45 hips from 44 patients who underwent nTHA between January 2020 and March 2021 with the same target cup orientation at the Department of Orthopedic Surgery at Ozu Memorial Hospital, Japan.
