Endocannabinoid contributions to the perception of socially relevant, affective touch in humans.

Neuropsychopharmacology

January 2025

Department of Biomedical and Clinical Sciences, Center for Social and Affective Neuroscience, Linköping University, Linköping, Sweden.

Social relationships are central to well-being. A subgroup of afferent nerve fibers, C-tactile (CT) afferents, are primed to respond to affective, socially relevant touch and may mitigate the effects of stress. The endocannabinoid ligand anandamide (AEA) modulates both social reward and stress.

Psychological states influence our happiness and productivity; however, estimates of their impact have historically been assumed to be limited by the accuracy with which introspection can quantify them. Over the last two decades, studies have shown that introspective descriptions of psychological states correlate with objective indicators of cognition, including task performance and metrics of brain function, using techniques like functional magnetic resonance imaging (fMRI). Such evidence suggests it may be possible to quantify the mapping between self-reports of experience and objective representations of those states (e.

Scaling and networking a modular photonic quantum computer.

Nature

January 2025

Xanadu Quantum Technologies Inc., Toronto, Ontario, Canada.

Photonics offers a promising platform for quantum computing, owing to the availability of chip integration for mass-manufacturable modules, fibre optics for networking and room-temperature operation of most components. However, experimental demonstrations are needed of complete integrated systems comprising all basic functionalities for universal and fault-tolerant operation. Here we construct a (sub-performant) scale model of a quantum computer using 35 photonic chips to demonstrate its functionality and feasibility.

In a dilute two-dimensional electron gas, Coulomb interactions can stabilize the formation of a Wigner crystal. Although Wigner crystals are topologically trivial, it has been predicted that electrons in a partially filled band can break continuous translational symmetry and time-reversal symmetry spontaneously, resulting in a type of topological electron crystal known as an anomalous Hall crystal. Here we report signatures of a generalized version of the anomalous Hall crystal in twisted bilayer-trilayer graphene, whose formation is driven by the moiré potential.

Numerous studies support the role of dopamine in modulating aggression, but the exact neural mechanisms remain elusive. Here we show that dopaminergic cells in the ventral tegmental area (VTA) can bidirectionally modulate aggression in male mice in an experience-dependent manner. Although VTA dopaminergic cells strongly influence aggression in novice aggressors, they become ineffective in expert aggressors.

Introduction: Psoriasis (PsO), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) may confer an increased risk for cardiovascular (CV) disease, including major adverse cerebro-cardiovascular events (MACE), deep vein thrombosis (DVT), and pulmonary embolism (PE). Patients with these conditions are often exposed for extended time periods to biologics, such as ixekizumab (IXE). Therefore, understanding the risk of CV events, especially MACE, in patients with PsO, PsA, and axSpA exposed to IXE is important.

Background: Early physician follow-up after hospital discharge is commonly recommended, though whether it mitigates adverse events is unclear. We conducted a systematic review and meta-analysis to examine the association between physician follow-up within 30 days of hospital discharge and risk of hospital readmission, emergency department (ED) visits, or mortality in medical patients.

Methods: MEDLINE, EMBASE, and CINAHL electronic databases were searched from inception to April 2023.

Huntington's disease, one of more than 50 inherited repeat expansion disorders, is a dominantly inherited neurodegenerative disease caused by a CAG expansion in HTT. Inherited CAG repeat length is the primary determinant of age of onset, with human genetic studies underscoring that the disease is driven by the CAG length-dependent propensity of the repeat to further expand in the brain. Routes to slowing somatic CAG expansion, therefore, hold promise for disease-modifying therapies.

Photothermal nanofiber-mediated photoporation for gentle and efficient intracellular delivery of macromolecules.

Nat Protoc

January 2025

Joint Laboratory of Advanced Biomedical Materials (NFU-UGent), Jiangsu Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, College of Chemical Engineering, Nanjing Forestry University, Nanjing, China.

Photoporation with free photothermal nanoparticles (NPs) is a promising technology for gentle delivery of functional biomacromolecules into living cells, offering great flexibility in terms of cell types and payload molecules. However, the translational use of photoporation, such as for transfecting patient-derived cells for cell therapies, is hampered by safety and regulatory concerns as it relies on direct contact between cells and photothermal NPs. A solution is to embed the photothermal NPs in electrospun nanofibers, which form a substrate for cell culture.

January 2025

National Clinical Research Center for Aging and Medicine at Huashan Hospital, MOE Key Laboratory of Computational Neuroscience and Brain-Inspired Intelligence, Institute of Science and Technology for Brain-Inspired Intelligence, Fudan University, Shanghai, 200433, PR China.

The striatum, a core brain structure relevant for schizophrenia, exhibits heterogeneous volumetric changes in this illness. Due to this heterogeneity, its role in the risk of developing schizophrenia following exposure to environmental stress remains poorly understood. Using the putamen (a subnucleus of the striatum) as an indicator for convergent genetic risk of schizophrenia, 63 unaffected first-degree relatives of patients (22.

Ultrasound is a first-line and often preferred imaging modality in the diagnosis of acute appendicitis. When the appendix is not visualised during a dedicated appendix ultrasound study, patients may require a CT study, which uses ionising radiation, or undergo conservative clinical observation with the inherent risk of clinical deterioration, perforation and sepsis. Median baseline data, at our hospital imaging department, revealed a rate of combined normal and abnormal appendix visualisation of 34.
