Protein-protein interactions (PPIs) are at the core of all key biological processes. However, the complexity of the structural features that determine PPIs makes their design challenging. We present BindCraft, an open-source and automated pipeline for protein binder design with experimental success rates of 10-100%.

Article Synopsis
  • California produces nearly all U.S. prunes, contributing significantly to the global market, with over 50% of new plantings using the Krymsk 86 rootstock due to its beneficial traits.
  • In spring 2023, 'Improved French' prune trees in Northern California showed signs of decline, with about 3.6% to 4.6% of trees affected based on rootstock type.
  • Investigation revealed the presence of prune brown line (PBL) disease caused by tomato ringspot virus (ToRSV), confirming infection through RNA testing from various tree samples.

Corticostriatal projection neurons from prelimbic medial prefrontal cortex to the nucleus accumbens core critically regulate drug-seeking behaviors, yet the underlying encoding dynamics whereby these neurons contribute to drug seeking remain elusive. Here we use two-photon calcium imaging to visualize the activity of corticostriatal neurons in mice from the onset of heroin use to relapse. We find that the activity of these neurons is highly heterogeneous during heroin self-administration and seeking, with at least 8 distinct neuronal ensembles that display both excitatory and inhibitory encoding dynamics.

Objectives: People living with dementia often experience behavioural and psychological symptoms of dementia (BPSD), which severely affect their well-being during the course of the disease. Particularly for BPSD outcomes, there is a high demand for increasing the evidence-based knowledge of non-pharmacological approaches, such as music-based interventions. Although previous reviews emphasize the potential effects of music-based interventions in people with dementia, they cover a wide range of different interventions and outcomes.

As coping profiles can offer concrete intervention opportunities, the goal of the present study is to explore latent coping profiles in a sample of 316 student teachers at a German university, using the Brief COPE inventory (Carver, 1997). Furthermore, we aim to test the extent to which students with specific coping profiles differ in the levels of stress (PSS; Schneider et al., 2020) and stressors they perceive.

Background: To date, there is no evidence supporting the existence of an association between Autism Spectrum Disorder (ASD) and extremism in the general population. However, there is increasing recognition that several features of ASD may provide the context of vulnerability to engage in extremist behaviour.

Aims: This paper sets out the case for a dedicated clinical approach to better integrate clinical risk appraisal processes with an assessment of ASD individuals' vulnerabilities within the Criminal Justice System.

In both prokaryotic and eukaryotic innate immune systems, TIR domains function as NADases that degrade the key metabolite NAD+ or generate signaling molecules. Catalytic activation of TIR domains requires oligomerization, but how this is achieved varies in distinct immune systems. In the Short prokaryotic Argonaute (pAgo)/TIR-APAZ (SPARTA) immune system, TIR NADase activity is triggered upon guide RNA-mediated recognition of invading DNA by an unknown mechanism.

Lack of behavioral suppression typifies substance use disorders, yet the neural circuit underpinnings of drug-induced behavioral disinhibition remain unclear. Here, we employ deep-brain two-photon calcium imaging in heroin self-administering mice, longitudinally tracking adaptations within a paraventricular thalamus to nucleus accumbens behavioral inhibition circuit from the onset of heroin use to reinstatement. We find that select thalamo-accumbal neuronal ensembles become profoundly hypoactive across the development of heroin seeking and use.

Autistic adults experience significant unmet healthcare needs, with opportunities for improvement in both the systems and the practitioners who serve this population. Primary care physicians/practitioners (PCPs) are a natural choice to provide comprehensive care to autistic adults but often lack experience in serving this population. This pilot study developed and tested an Extension for Community Healthcare Outcomes (ECHO) Autism model adapted from our previous work, focused specifically on training PCPs in best-practice care for autistic adults.

Clinical and preclinical studies indicate that adaptations in corticostriatal neurotransmission significantly contribute to heroin relapse vulnerability. In animal models, heroin self-administration and extinction produce cellular adaptations in both neurons and astrocytes within the nucleus accumbens (NA) core that are required for cue-induced heroin seeking. Specifically, decreased glutamate clearance and reduced association of perisynaptic astrocytic processes with NAcore synapses allow glutamate release from prelimbic (PrL) cortical terminals to engage synaptic and structural plasticity in NAcore medium spiny neurons.

Background: Dementia risk reduction is a public health priority and general practitioners (GPs) play a pivotal role in preventative healthcare. Therefore, risk assessment tools should be designed with GPs' preferences and perspectives in mind.

Objective: The LEAD! GP project aimed to investigate Australian GPs' preferences and perspectives relating to design, use and implementation of a new risk assessment tool that simultaneously calculates risk for four outcomes- dementia, diabetes mellitus, myocardial infarct, and stroke.

Background: People experiencing cognitive concerns and symptoms of depression or anxiety are at risk for Alzheimer's disease and dementia. We know physical activity can benefit cognition but understanding how to best support engagement is an ongoing challenge. Evidence-based conceptual models of factors underpinning physical activity engagement in target populations can inform intervention tailoring to address this challenge.

Management of plant-parasitic nematodes uses host plant resistance, crop rotation, cultural methods, and nematicide applications. Host plant resistance is tedious to develop, and crop rotation and cultural methods are challenging to use. Environmental and human health concerns render sole reliance on chemical nematode suppression nonsustainable.

Suppression of dangerous or inappropriate reward-motivated behaviors is critical for survival, whereas therapeutic or recreational opioid use can unleash detrimental behavioral actions and addiction. Nevertheless, the neuronal systems that suppress maladaptive motivated behaviors remain unclear, and whether opioids disengage those systems is unknown. In a mouse model using two-photon calcium imaging in vivo, we identify paraventricular thalamostriatal neuronal ensembles that are inhibited upon sucrose self-administration and seeking, yet these neurons are tonically active when behavior is suppressed by a fear-provoking predator odor, a pharmacological stressor, or inhibitory learning.

Guina summarize the literature on neurodevelopmental conditions and crime, focusing on the use of the insanity plea for this population. There have been a small number of cases in several jurisdictions, using both cognitive and volitional prongs, generating questions about the use of the defense for people with neurodevelopmental conditions. There are theoretical scenarios in which the defense seems appropriate, such as the argument that higher order moral reasoning is contingent on a series of developmental steps, including the development of theory of mind.
