Carbon and other volatiles in the form of gases, fluids or mineral phases are transported from Earth's surface into the mantle at convergent margins, where the oceanic crust subducts beneath the continental crust. The efficiency of this transfer has profound implications for the nature and scale of geochemical heterogeneities in Earth's deep mantle and shallow crustal reservoirs, as well as Earth's oxidation state. However, the proportions of volatiles released from the forearc and backarc are not well constrained compared to fluxes from the volcanic arc front.

Compulsive tendencies are a central feature of problematic human behavior and thereby are of great interest to the scientific and clinical community. However, no consensus exists about the precise meaning of 'compulsivity,' creating confusion in the field and hampering comparison across psychiatric disorders. A vague conceptualization makes compulsivity a moving target encompassing a fluctuating variety of behaviors, which is unlikely to improve the new dimension-based psychiatric or psychopathology approach.

Objective: Young adulthood is a crucial neurodevelopmental period during which impulsive and compulsive problem behaviours commonly emerge. While traditionally considered diametrically opposed, impulsive and compulsive symptoms tend to co-occur. The objectives of this study were as follows: (a) to identify the optimal trans-diagnostic structural framework for measuring impulsive and compulsive problem behaviours, and (b) to use this optimal framework to identify common/distinct antecedents of these latent phenotypes.

Deep-sea hydrothermal vents are a significant source of dissolved metals to the global oceans, producing midwater plumes enriched in metals that are transported thousands of kilometers from the vent source. Particle precipitation upon emission of hydrothermal fluids controls metal speciation and the magnitude of metal export. Here, we document metal sulfide particles, including pyrite nanoparticles, within the first meter of buoyant plumes from three high-temperature vents at the East Pacific Rise.

Background: Cytotoxic and immunosuppressive therapies for cancer treatment may allow hepatitis reactivation. Hepatitis due to viral hepatitis reactivation is detected in 14%-25% of hepatitis B surface antigen (HBsAg)-positive cancer patients undergoing anticancer treatments. Drug toxicity may be confused with hepatitis reactivation, which may cause a delay in diagnosis.

Objective: We assessed self-reported drives for alcohol use and their impact on clinical features of alcohol use disorder (AUD) patients. Our prediction was that, in contrast to "affectively" (reward or fear) driven drinking, "habitual" drinking would be associated with worse clinical features in relation to alcohol use and higher occurrence of associated psychiatric symptoms.

Methods: Fifty-eight Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol abuse patients were assessed with a comprehensive battery of reward- and fear-based behavioral tendencies.

A recent review on the use of electroconvulsive therapy (ECT) in obsessive-compulsive-related disorders (OCRDs) identified reports of trichotillomania (TTM) in only three patients, but it did not describe the specific effect of ECT on hair-pulling behaviors. The authors present a case report of Mrs. A, a 77-year-old widowed housewife with a lifelong history of episodic TTM and bipolar disorder who was effectively treated with ECT.

Substance use disorder is characterized by repeated use of a substance, leading to clinically significant distress, making it a serious public health concern. The endocannabinoid system plays an important role in common neurobiological processes underlying substance use disorder, in particular by mediating the rewarding and motivational effects of substances and substance-related cues. In turn, a number of cannabinoid drugs (e.

This study investigated the effect of different nitrogen sources, namely, ammonium chloride and glutamate, on photoheterotrophic metabolism of Rhodobacter capsulatus grown on acetate as the carbon source. Genes that were significantly differentially expressed according to Affymetrix microarray data were categorized into Clusters of Orthologous Groups functional categories and those in acetate assimilation, hydrogen production, and photosynthetic electron transport pathways were analyzed in detail. Genes related to hydrogen production metabolism were significantly downregulated in cultures grown on ammonium chloride when compared to those grown on glutamate.

Objectives: We aimed to compare the plasma levels of biomarkers such as: serum Gal-3, H-FABP, cTnI, and CK-MB in patients, who were admitted to the emergency room with chest pain, and to determine whether these biomarkers have early diagnostic value of acute coronary syndrome (ACS).

Methods: The study was performed in 60 patients aged ≥ 18 years, who were admitted to emergency room. These patients were divided into 3 groups: patients with STEMI (group I, n = 20), patients with NSTEMI (group II, n = 20), and patients with USAP (group III, n = 20).

Article Synopsis
  • - The study investigates how near-miss outcomes in slot machine gambling affect physiological responses, specifically heart rate (HR) and gambling behavior, using immersive virtual reality (VR) instead of traditional computer simulations.
  • - Participants experienced increased HR in response to near-misses and losses, indicating a heightened state of arousal, but there was no distinct difference between near-misses and losses regarding HR and time taken to initiate the next spin.
  • - Impulsivity did not correlate with responses to near-misses, suggesting that the thrill from losses may be a stronger motivator for gambling behavior than near-misses. The research calls for further studies, especially focusing on individuals with gambling problems for more accurate insights.

Aerobic exercise (AE) interventions represent promising therapeutic approaches in disorders that compromise hippocampal integrity, but a more comprehensive account of the neural mechanisms stimulated by AE in the human brain is needed. We conducted a longitudinal pilot-study to assess the impact of a 12-week AE intervention on hippocampal structure and function in 10 healthy, human participants (50% females; 25-59 years). Using a novel combination of multimodal MRI techniques, we found significant increases in left hippocampal volume, Cornu Ammonis subfield area 1, NAA concentration and immediate verbal recall performance.

Background: Error processing and inhibitory control enable the adjustment of behaviors to meet task demands. Functional magnetic resonance imaging studies report brain activation abnormalities in patients with obsessive-compulsive disorder (OCD) during both processes. However, conclusions are limited by inconsistencies in the literature and small sample sizes.

In this study, we integrated geochemical measurements, microbial diversity surveys and physiological characterization of laboratory strains to investigate substrate-attached filamentous microbial biofilms at Tor Caldara, a shallow-water gas vent in the Tyrrhenian Sea. At this site, the venting gases are mainly composed of CO and HS and the temperature at the emissions is the same as that of the surrounding water. To investigate the composition of the total and active fraction of the Tor Caldara biofilm communities, we collected established and newly formed filaments and we sequenced the 16S rRNA genes (DNA) and the 16S rRNA transcripts (cDNA).

Cannabis exerts its psychoactive effect through cannabinoid receptors that are widely distributed across the cortical surface of the human brain. It is suggested that cannabis use may contribute to structural alterations across the cortical surface. In a large, multisite dataset of 120 controls and 141 cannabis users, we examined whether differences in key characteristics of the cortical surface - including cortical thickness, surface area, and gyrification index were related to cannabis use characteristics, including (i) cannabis use vs.
