The impact of non-native trees on galling and herbivory in New York City across space and timeNARA Subscribed
Cities and suburbs frequently plant native and non-native trees as foundation species, with non-natives cultivated in these areas for centuries while remaining non-invasive. Although previous research has found that native trees often host more arthropods, studies have not simultaneously looked across space and time to determine the consistency of tree origin on urban arthropods. We combined varied methods across spatial and t...
Purpose Deepwater Horizon oil spill (DWHOS) responders potentially experienced multiple stressors. We examined associations between DWHOS deployment-related stressor patterns and neurological and endocrine/metabolic conditions among U.S. Coast Guard active duty responders who completed post-deployment surveys (n = 3102). Methods Deployment-related stressor patterns were identified using principal component analysis of self-rep...
Skin sebaceous glands (SGs) synthesize and secrete sebum, a mixture of lipids and cellular debris that defends the external body surface against physicochemical challenges. Recent data define the SG as a dynamic entity with potential functions beyond skin protection, including immunomodulatory actions and the regulation of energy metabolism. We postulate that the SG also has important, unrecognized roles in physiological and p...
The P2RX7 gene has been linked to various neuropsychiatric disorders. In particular, the SNP rs2230912, which results in a glutamine-to-arginine substitution at position 460, has repeatedly been associated with mood disorders. Although this SNP per se does not affect receptor function, it tags a gain-of-function haplotype that has been shown to significantly enhance receptor activity. BAC-transgenic P2X7-reporter mice have pro...
The deep ocean, while home to a remarkable diversity of life, remains one of the least understood environments on Earth. This profound lack of information hampers our ability to protect and manage deep-sea ecosystems effectively, especially as they face escalating threats from human activities such as resource extraction, pollution, and climate change. In light of these knowledge gaps, this study investigates the diversity of...
Alzheimer’s disease (AD) is the leading cause of dementia and evidence suggests that alcohol, the most commonly used addictive substance, may increase AD risk. Locus coeruleus (LC) neurons are the primary source of norepinephrine in the brain and these neurons degenerate early in AD. In rodent models, lesioning the LC increases amyloid beta (Aβ) pathology suggesting that LC integrity and norepinephrine signaling obstruct Aβ pa...
Cancer Risk and Mortality Following Kaposi Sarcoma Among People with HIV in the United States, 2000 to 2019NARA Subscribed
People with HIV (PWH) have increased Kaposi sarcoma (KS) risk. Among 2,645 PWH with KS in the United States HIV/AIDS Cancer Match Study, subsequent cancer risk was elevated 2.8-fold (95% confidence interval [CI]: 2.4–3.3) compared to PWH without KS. Mortality after KS declined 2000–2002 and 2012–2015 (hazard ratio = 0.64; 95%CI: 0.55–0.74).
The CALHM1 blocker CGP37157 increases seizure severity during status epilepticus in adult miceNARA Subscribed
Epilepsy is one of the most common chronic brain diseases affecting up to 70 million people worldwide. Major challenges of epilepsy treatment include the high pharmacoresistance in patients and the lack of disease-modification. Extracellular adenosine 3’triphosphate (ATP), a key neurotransmitter in the activation of the purinergic signalling system, is increasingly recognized to contribute to pathological brain hyperexcitabili...
