Background: The effect of statins use on the incidence of Alzheimer's disease (AD) is still under debate, and it could be modified by a series of factors.

Objectives: We aimed to examine the association of statins use with the risk of cognitive impairment and AD, and assess the moderating roles of genetic susceptibility and other individual-related factors.

Design: A longitudinal study was conducted from the UK Biobank where individuals completed baseline surveys (2006-2010) and were followed (mean follow-up period: 9 years).

Background: Clinical predictors of treatment-resistant depression could improve treatment strategies. Depressive symptom profiles at baseline are potential outcome predictors, but little evidence is available, and sex-specific profiles have been scarcely investigated.

Methods: Baseline symptom scores of 1294 patients with major depressive disorder were assessed by the Montgomery-Åsberg depression rating scale (MADRS) as part of a multicenter study by the "Group for the Studies of Resistant Depression".

The radiotracer [F]JK-PSMA-7, a prostate cancer imaging agent for positron emission tomography (PET), was previously synthesized by indirect radiofluorination using an F-labeled active ester as a prosthetic group, which had to be isolated and purified before it could be linked to the pharmacologically active Lys-urea-Glu motif. Although this procedure could be automated on two-reactor modules like the GE TRACERLab FX2N (FXN) to afford the tracer in modest radiochemical yields (RCY) of 18-25%, it is unsuitable for cassette-based systems with a single reactor. To simplify implementation on an automated synthesis module, the radiosynthesis of [F]JK-PSMA-7 was devised as a one-pot, two-step reaction.

Gestational diabetes mellitus (GDM) presents significant risks for both maternal and neonatal health, affecting fetal growth and increasing the likelihood of future diabetes mellitus (DM) development in affected women. The dysregulation of metabolic biomarkers, including catestatin, has been implicated in GDM pathophysiology. However, the clinical significance of catestatin in GDM remains poorly understood, particularly in the context of different therapeutic approaches.

In recent decades, the scientific community has faced a major challenge in the search for new therapies that can slow down or alleviate the process of neuronal death that accompanies neurodegenerative diseases. This study aimed to identify an effective therapy using neurotrophic factors to delay the rapid and aggressive cerebellar degeneration experienced by the Purkinje Cell Degeneration (PCD) mouse, a model of childhood-onset neurodegeneration with cerebellar atrophy (CONDCA). Initially, we analyzed the changes in the expression of several neurotrophic factors related to the degenerative process itself, identifying changes in insulin-like growth factor 1 (IGF-1) and Vascular Endothelial Growth Factor B (VEGF-B) in the affected animals.

Developmental and epileptic encephalopathies (DEEs) are a group of neuropediatric diseases associated with epileptic seizures, severe delay or regression of psychomotor development, and cognitive and behavioral deficits. What sets DEEs apart is their complex interplay of epilepsy and developmental delay, often driven by genetic factors. These two aspects influence one another but can develop independently, creating diagnostic and therapeutic challenges.

Forensic mental health services (FMHS) involve restricting certain individual rights to uphold or promote other ethical values - the restriction of liberty in various forms is justified with reference to health and safety of the individual and the community. The tension that arises from this has been construed as a hallmark of the practice and an ever-present quandary for practitioners. Stating this ethical dilemma upfront is a common point of departure for many texts discussing FMHS.

Department of Neurology, Fujian Key Laboratory of Molecular Neurology, Fujian Institute of Neurology, The First Affiliated Hospital, Fujian Medical University, Key Laboratory of Brain Aging and Neurodegenerative Diseases of Fujian Medical University, 20 Chazhong Road, Fuzhou, 350005, China.

Peripheral neuropathy (PN) identified as a significant contributor to disability in Spinocerebellar ataxia type 3 (SCA3) patients. This study seeks to assess the utility of current perception threshold (CPT) measurements in evaluating PN in individuals with SCA3 and aims to identify factors influencing CPT values in SCA3 and ascertain whether these values correlate with the severity of ataxia. Ninety-four patients diagnosed with SCA3 and 44 healthy controls were recruited for this investigation.

Understanding mammalian preimplantation development, particularly in humans, at the proteomic level remains limited. Here, we applied our comprehensive solution of ultrasensitive proteomic technology to measure the proteomic profiles of oocytes and early embryos and identified nearly 8,000 proteins in humans and over 6,300 proteins in mice. We observed distinct proteomic dynamics before and around zygotic genome activation (ZGA) between the two species.

Assembly and architecture of endogenous NMDA receptors in adult cerebral cortex and hippocampus.

University of Chinese Academy of Sciences, Beijing, China; Institute of Neuroscience, CAS Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences, Shanghai 200031, China. Electronic address:

The cerebral cortex and hippocampus are crucial brain regions for learning and memory, which depend on activity-induced synaptic plasticity involving N-methyl-ᴅ-aspartate receptors (NMDARs). However, subunit assembly and molecular architecture of endogenous NMDARs (eNMDARs) in the brain remain elusive. Using conformation- and subunit-dependent antibodies, we purified eNMDARs from adult rat cerebral cortex and hippocampus.

More than a century of research shows that spaced learning improves long-term memory. However, there remains debate concerning why that is. A major limitation to resolving theoretical debates is the lack of evidence for how neural representations change as a function of spacing.

Experiencing music often entails the perception of a periodic beat. Despite being a widespread phenomenon across cultures, the nature and neural underpinnings of beat perception remain largely unknown. In the last decade, there has been a growing interest in developing methods to probe these processes, particularly to measure the extent to which beat-related information is contained in behavioral and neural responses.

Introduction: Lewy body dementia (LBD) shares genetic risk factors with Alzheimer's disease (AD), including apolipoprotein E (APOE), but is distinguishable at the genome-wide level. Polygenic risk scores (PRS) may therefore improve diagnostic classification.

Methods: We assessed diagnostic classification using AD-PRS excluding APOE (AD-PRS ), APOE risk score (APOE-RS), and plasma phosphorylated tau 181 (p-tau181), in 83 participants with LBD, 27 with positron emission tomography amyloid beta (Aβ)positive mild cognitive impairment or AD (MCI+/AD), and 57 controls.

There has been both a national and global emphasis within the past 3 years to promote diversity, equity, inclusion (DEI), and cultural respect in healthcare and academia. One discipline and healthcare arena where this has been evident is the psychology field. Indeed, there has been rampant and widespread adoption and advancement of DEI and cultural respect across most of psychology.

Objective: The objective of this study was to examine the effect of observing actions at different speeds on the speed of motor task performance in subsequent actions.

Methods: Sixty individuals, divided equally between those with non-specific chronic low back pain (NSCLBP) and asymptomatic subjects, were enrolled. Participants were further split into subgroups to observe lumbar flexion and Timed Up and Go (TUG) test actions at either a slow or fast pace, following a randomized assignment.

Background: Schizophrenia is hypothesized to involve a disturbance in the temporal dynamics of self-processing, specifically within the interoceptive, exteroceptive, and cognitive layers of the self. This study aimed to investigate the intrinsic neural timescales (INTs) within these self-processing layers among people with schizophrenia.

Methods: We conducted a functional magnetic resonance imaging (fMRI) study to investigate INTs, as measured by the autocorrelation window, among people with schizophrenia and healthy controls during both resting-state and task (memory encoding and retrieval) conditions.
