From relaxed beliefs under psychedelics (REBUS) to revised beliefs after psychedelics (REBAS).

The Relaxed Beliefs Under pSychedelics (REBUS) model proposes that serotonergic psychedelics decrease the precision weighting of neurobiologically-encoded beliefs. We conducted a preliminary examination of two psychological assumptions of REBUS: (a) psychedelics foster acute relaxation and post-acute revision of confidence in mental-health-relevant beliefs; which (b) facilitate positive therapeutic outcomes and are associated with the entropy of EEG signals. Healthy individuals (N = 11) were administered 1 mg and 25 mg psilocybin 4-weeks apart.

Precession modulates the poleward expansion of atmospheric circulation to the Arctic Ocean.

Under sustained global warming, Arctic climate is projected to become more responsive to changes in North Pacific meridional heat transport as a result of teleconnections between low and high latitudes, but the underlying mechanisms remain poorly understood. Here, we reconstruct subarctic humidity changes over the past 400 kyr to investigate the role of low-to-high latitude interactions in regulating Arctic hydroclimate. Our reconstruction is based on precipitation-driven sediment input variations in the Subarctic North Pacific (SANP), which reveal a strong precessional cycle in subarctic humidity under the relatively low eccentricity variations that dominated the past four glacial-interglacial cycles.

Academic Achievement, Externalizing Problems, and Close Friends in Middle School: Testing a Developmental Cascade Model Leading to Educational Attainment in the Late Twenties.

Because educational attainment is associated with well-being in the long term, it is important to understand the developmental processes that enhance academic outcomes during adolescence. Also, although the importance of friends is well documented in adolescence, little is known about how close friends' characteristics work together with youth's own characteristics to shape adolescents' educational trajectories. This study fills an important gap in knowledge by focusing on how middle school students' academic achievement and externalizing problems are associated with their friends' achievement and externalizing problems over time, and how these variables predict educational attainment in adulthood.

Solid state NMR spectral editing of histidine, arginine and lysine using Hadamard encoding.

The NMR signals from protein sidechains are rich in information about intra- and inter-molecular interactions, but their detection can be complicated due to spectral overlap as well as conformational and hydrogen exchange. In this work, we demonstrate a protocol for multi-dimensional solid-state NMR spectral editing of signals from basic sidechains based on Hadamard matrix encoding. The Hadamard method acquires multi-dimensional experiments in such a way that both the backbone and under-sampled sidechain signals can be decoded for unambiguous editing in the N spectral frequency dimension.

Comparison of Pharmacokinetics of Long-Acting Local Analgesics: CPL-01, a Novel Extended-Release Ropivacaine, Demonstrates Consistent and Predictable Exposure Compared with Liposomal Bupivacaine.

Background And Objective: There is a significant medical need for improved long-acting local anesthetics to decrease postsurgical pain and reduce postoperative opioid use. While ropivacaine is considered a safer local anesthetic than bupivacaine, no long-acting ropivacaine formulation is currently marketed. Available formulations of bupivacaine show inconsistent pharmacokinetics (PK) among different surgical models, and inconsistency in PK may lead to a reluctance to use the medication owing to fear of local anesthetic systemic toxicity (LAST) or unreliable efficacy.

Sources of Microstructure in Mammalian Cochlear Responses.

Quasiperiodic fluctuations with frequency are observed in a variety of responses that either originate from or strongly depend on the cochlea's active mechanics. These spectral microstructures are unique and stable features of individual ears and have been most thoroughly studied in behavioral hearing thresholds and otoacoustic emissions (OAEs). While the exact morphology of the microstructure patterns may differ across measurement types, the patterns are interrelated and are thought to depend on common mechanisms.

Epigenetic Control of Hyperuricemia and Gout by Gene Writer DNMT1 and RNA Editor ADAR1: Mechanism of Gout and Amyloid Dissolution in Down Syndrome.

Although DNA methyltransferase 1 (DNMT1) and RNA editor ADAR triplications exist in Down syndrome (DS), their specific roles remain unclear. DNMT methylates DNA, yielding S-adenosine homocysteine (SAH), subsequently converted to homocysteine (Hcy) and adenosine by S-adenosine homocysteine (Hcy) hydrolase (SAHH). ADAR converts adenosine to inosine and uric acid.
