Distinct Dispersal Directions Out of the Qinghai–Tibet Plateau Resulted in Contrasting Evolutionary TrajectoriesNARA Subscribed
Aim The Qinghai–Tibet Plateau (QTP) harbours high levels of species diversity and endemism, and multiple out‐of‐QTP dispersal routes have been put forward. However, whether different dispersal directions out of the QTP resulted in contrasting evolutionary trajectories remains unknown. Here, we use the sister genera Calathodes and Trollius (Ranunculaceae) as an ideal model to investigate the out‐of‐QTP diversification patterns....
Rosalinda incrustans (Kramp, 1947) is a poorly known, deep-sea capitate hydrozoan whose biology, morphology, and ecological traits have remained largely obscure due to the rarity of collected material and its small, inconspicuous epibiontic habitus. Since its original description, the species has been collected only twice and recorded two additional times with Remotely Operated Vehicles (ROVs), invariably observed as an epibio...
96-h methamphetamine self-administration elicits striatal dopamine depletion in male and female rats: a model of binge-like useNARA Subscribed
Background Methamphetamine is a psychostimulant with significant public health implications. Chronic methamphetamine use is linked to profound dysregulation of the dopaminergic system, cognitive deficits, and psychiatric symptoms. While traditional experimenter administered “binge” dosing models reliably produce dopaminergic neurotoxicity, they fail to capture the volitional, drug intake characteristic of human methamphetamine...
Traumatic brain injury (TBI) causes lasting neurological impairments, particularly learning and memory deficits associated with hippocampal damage. Emerging evidence suggests that hippocampal vulnerability may be linked to bioenergetic dysfunction, though its role remains poorly defined. A deeper understanding of post-TBI metabolic disturbances and their association with pathological outcomes could reveal novel therapeutic tar...
Introduction Peripheral arterial stiffness measured with pulse wave velocity (PWV) is reduced 5-min after an acute bout of dynamic exercise. The mechanism for the reduction in peripheral arterial stiffness is unknown. We hypothesized that increased blood flow and compression of the vasculature are potential mechanisms involved in post-exercise reduction in peripheral arterial stiffness. Methods Brachial-radial PWV was measured...
Stroke Mechanisms in Intracranial Atherosclerotic Disease: A Modified Classification System and Clinical ImplicationsNARA Subscribed
Background In patients with symptomatic intracranial atherosclerotic stenosis (sICAS), recent evidence has suggested an association between artery-to-artery embolism (AAE) and cortical borderzone (CBZ) infarcts. Methods We recruited patients with 50–99% anterior-circulation sICAS in this cohort. Stroke mechanisms were categorized as isolated parent artery atherosclerosis occluding penetrating artery (PAO), isolated AAE, isolat...
Purpose Black women are 30% more likely to die of ovarian cancer than White women. Discrimination may affect cancer health disparities through pathways including socioeconomic disadvantage, chronic stress, and access to care. In this study, we evaluated associations of discrimination and trust in physicians with all-cause mortality among Black women with ovarian cancer. Methods Using data from the African American Cancer Epide...
Grazing by sea urchins is a potential co‐driver of Greenland kelp forest distributionNARA Subscribed
Grazing by sea urchins is a main driver of kelp forest dynamics causing shifts from kelp forests to urchin barrens in the temperate region but there is limited information on such patterns from the Arctic region. Based on information from 132 underwater video transects along Greenland's West Coast at 59.9–77.8°N, we explored the distribution of kelps and sea urchins, including the occurrence of sea urchin barrens, along latitu...
