MDMA enhances empathy-like behaviors in mice via 5-HT release in the nucleus accumbens.

MDMA (3,4-methylenedioxymethamphetamine) is a psychoactive drug with powerful prosocial effects. While MDMA is sometimes termed an "empathogen," empirical studies have struggled to clearly demonstrate these effects or pinpoint underlying mechanisms. Here, we paired the social transfer of pain and analgesia-behavioral tests modeling empathy in mice-with region-specific neuropharmacology, optogenetics, and transgenic manipulations to explore MDMA's action as an empathogen.

Long-Term Second Malignancies in Prostate Cancer Patients Treated With Low-Dose-Rate Brachytherapy and Radical Prostatectomy.

Purpose: Second malignancy is a rare but potentially lethal event after prostate brachytherapy, but data remain scarce on its long-term risk. The objective of this study is to estimate the number of pelvic second malignancies following brachytherapy compared to radical prostatectomy (RP).

Materials And Methods: We retrospectively reviewed patients treated with low-dose I brachytherapy and RP in British Columbia from 1999 to 2010.

Comprehensive phylogeny of Pieridae butterflies reveals strong correlation between diversification and temperature.

Temperature is thought to be a key factor influencing global species richness patterns. We investigate the link between temperature and diversification in the butterfly family Pieridae by combining next generation DNA sequences and published molecular data with fine-grained distribution data. We sampled nearly 600 pierid butterfly species to infer the most comprehensive molecular phylogeny of the family and curated a distribution dataset of more than 800,000 occurrences.

Molecular Insights into O-Linked Sialoglycans Recognition by the Siglec-Like SLBR-N (SLBR) of .

is a Gram-positive bacterial species that typically colonizes the human oral cavity, but can also cause local or systemic diseases. Serine-rich repeat (SRR) glycoproteins exposed on the bacterial surface bind to sialylated glycans on human salivary, plasma, and platelet glycoproteins, which may contribute to oral colonization as well as endocardial infections. Despite a conserved overall domain organization of SRR adhesins, the Siglec-like binding regions (SLBRs) are highly variable, affecting the recognition of a wide range of sialoglycans.

Temporal variations in female moose responses to roads and logging in the absence of wolves.

Animal movements, needed to acquire food resources, avoid predation risk, and find breeding partners, are influenced by annual and circadian cycles. Decisions related to movement reflect a quest to maximize benefits while limiting costs, especially in heterogeneous landscapes. Predation by wolves () has been identified as the major driver of moose () habitat selection patterns, and linear features have been shown to increase wolf efficiency to travel, hunt, and kill prey.

Successful treatment of stage IVB ovarian carcinosarcoma with PARP Inhibitor: A case report.

•Ovarian carcinosarcoma is a rare ovarian cancer histology that has limited treatment options.•In this study, we present an unusual association between carcinosarcoma and a STIC lesion.•In select patients with carcinosarcoma, PARP inhibition may provide clinical benefit.

Constructing a model including the cryptic sulfur cycle in Chesapeake Bay requires judicious choices for key processes and parameters.

A new biogeochemical model for Chesapeake Bay has been developed by merging two published models - the ECB model of Da et al. (2018) that has been calibrated for the Bay but only simulates nitrogen, carbon and oxygen and the BioRedoxCNPS model of al Azhar et al. (2014) and Hantsoo et al.

Regional anaesthesia training in the UK - a national survey.

Background: Adequate training of anaesthetists in regional anaesthesia is important to ensure optimal patient access to regional anaesthesia.

Methods: We undertook a national survey of UK trainee anaesthetists and Royal College of Anaesthetists (RCoA) tutors to assess experiences of training in regional anaesthesia. We performed descriptive statistics for baseline characteristics, and logistic regression of training indices and tutor confidence that their hospital could provide regional anaesthesia training at all three stages of the RCoA 2021 curriculum.

Are parent-reported sleep logs essential? A comparison of three approaches to guide open source accelerometry-based nocturnal sleep processing in children.

We examined the comparability of children's nocturnal sleep estimates using accelerometry data, processed with and without a sleep log. In a secondary analysis, we evaluated factors associated with disagreement between processing approaches. Children (n = 722, age 5-12 years) wore a wrist-based accelerometer for 14 days during Autumn 2020, Spring 2021, and/or Summer 2021.

Longitudinal associations between the quality of family interactions and school-age children's narrative abilities in the context of financial insecurity.

This longitudinal study investigates whether the quality of family interactions at 3-5 years of age predicts narrative abilities in 7-9-year-old children from socioeconomically disadvantaged families. The sample consists of 67 children and their parents receiving social welfare. Family interactions were filmed during mealtime at home and coded using the Mealtime Interaction Coding System.

The Impact of a Lifestyle Intervention on Postpartum Cardiometabolic Risk Factors Among Hispanic Women With Abnormal Glucose Tolerance During Pregnancy: Secondary Analysis of a Randomized Trial.

Background: Women with abnormal glucose tolerance during pregnancy are at risk for cardiovascular disease (CVD), with higher rates among Hispanics. However, studies on the impact of lifestyle interventions on postpartum CVD profiles are sparse.

Methods: This is a secondary analysis of a controlled trial among a subsample of Hispanic women with abnormal glucose tolerance participating in Estudió PARTO (Project Aiming to Reduce Type twO diabetes; mean age = 28.

Is Engineered Tissue the Future of Bladder Reconstruction: Con.

Tissue engineering, once promising, faces significant technical challenges. Current limitations impede progression of the field, as evidenced by clinical trial failures over the past decades. Existing established surgical techniques remain the only proven, successful, and durable methods for bladder reconstruction.

Brain decoding of the Human Connectome Project tasks in a dense individual fMRI dataset.

Brain decoding aims to infer cognitive states from patterns of brain activity. Substantial inter-individual variations in functional brain organization challenge accurate decoding performed at the group level. In this paper, we tested whether accurate brain decoding models can be trained entirely at the individual level.

A disordered region controls cBAF activity via condensation and partner recruitment.

Intrinsically disordered regions (IDRs) represent a large percentage of overall nuclear protein content. The prevailing dogma is that IDRs engage in non-specific interactions because they are poorly constrained by evolutionary selection. Here, we demonstrate that condensate formation and heterotypic interactions are distinct and separable features of an IDR within the ARID1A/B subunits of the mSWI/SNF chromatin remodeler, cBAF, and establish distinct "sequence grammars" underlying each contribution.
