Despite significant progress in understanding the factors influencing cognitive function in Parkinson's disease (PD), there is a notable gap in data representation for the Latinx population. This study aims to evaluate the contributors to and disparities in cognitive performance among Latinx patients with PD. A retrospective analysis was conducted based on cross-sectional data encompassing demographic, environmental, motor, and non-motor disease characteristics from the Latin American Research Consortium on the Genetics of PD (LARGE-PD) and the Parkinson's Progression Markers Initiative (PPMI) cohorts.

In subjects implanted with intracranial electrodes, we use two different stories involving the same person (or place) to evaluate whether and to what extent context modulates human single-neuron responses. Nearly all neurons (97% during encoding and 100% during recall) initially responding to a person/place do not modulate their response with context. Likewise, nearly none (<1%) of the initially non-responsive neurons show conjunctive coding, responding to particular persons/places in a particular context during the tasks.

Introduction: During revision surgery for the management of patients presenting with long-bone upper extremity nonunion, it is crucial to rule out fracture-related infection (FRI). This is especially true if there are clinical signs suggestive of FRI, or if there is a history of prior FRI, open wound fracture, or surgery. This study aimed to determine the efficacy of frozen section analysis (FSA) in providing real-time diagnosis of FRI in patients with upper-limb long-bone nonunion undergoing revision surgery.

The goal of this paper is to explore a set of epistemological and ontological issues regarding the historical and philosophical role of placebos in the contested history of antidepressants. Starting from an account of the dual nature of the placebo as both an epistemic and a therapeutic tool, and against the background of the heated debates on the efficacy of second-generation antidepressants, I propose two related arguments. First, I argue that placebos as controls played a crucial but paradoxical role in the rise of so-called evidence-based approaches to depression.

The membrane dipole potential that arises from the interfacial water and constitutive dipolar groups of lipid molecules modulates the interaction of amphiphiles and proteins with membranes. Consequently, its determination for lipid mixtures resembling the existing diversity in biological membranes is very relevant. In this work, the dipole potentials of monolayers, formed at the air-water interface, from pure or mixed lipids (1-palmitoyl-2-oleoyl--glycero-3-phosphocholine (POPC), 1-palmitoyl-2-oleoyl--glycero-3-phosphoethanolamine (POPE), 1-palmitoyl-2-oleoyl--glycero-3-phosphatidyserine (POPS), sphingomyelin (SpM) and cholesterol) were measured and correlated with the mean area per lipid.

Different whole-brain computational models have been recently developed to investigate hypotheses related to brain mechanisms. Among these, the Dynamic Mean Field (DMF) model is particularly attractive, combining a biophysically realistic model that is scaled up via a mean-field approach and multimodal imaging data. However, an important barrier to the widespread usage of the DMF model is that current implementations are computationally expensive, supporting only simulations on brain parcellations that consider less than 100 brain regions.

Structural inequality, the uneven distribution of resources and opportunities, influences health outcomes. However, the biological embedding of structural inequality in aging and dementia, especially among underrepresented populations, is unclear. We examined the association between structural inequality (country-level and state-level Gini indices) and brain volume and connectivity in 2,135 healthy controls, and individuals with Alzheimer's disease and frontotemporal lobe degeneration from Latin America and the United States.

Turbulence is a universal principle for fast energy and information transfer. Moving beyond the turbulence of fluid dynamics, turbulence has recently been demonstrated in brain dynamics. Importantly, turbulence can be expressed as the rich variability across spacetime of the local levels of synchronisation of coupled brain signals.

Microplastics (MPs) are in some ways the expected product of man-made plastics that are considered as a pollutant ubiquitous in the environment. This is particularly notorious in continental waters, along coastlines, and especially in the North Pacific Gyre, sometimes called the Pacific Garbage Patch. Even now, there is growing concern that MPs can harm wildlife, enter the food chain, and end up in the human body.

Even though spontaneous retrieval of analogous cases lacking surface similarity with a target situation typically requires achieving an abstract representation of the target situation, recent studies on analogical argumentation suggest that the deliberate disposition to search for analogous cases in long-term memory (LTM) suffices to increase cross-domain retrieval significantly. However, a limitation of these studies concerns the impossibility to determine whether the analogous situations reported were invented rather than retrieved, and whether there were instances of analogical retrieval that were not reflected in participants' arguments. To overcome these shortcomings, Experiment 1 resorted to a traditional transfer paradigm where a base analogue is learned prior to the presentation of the target situation during a contextually-separated phase.

Disjunct distributions, characterised by spatially separated populations of related species, offer insights into historical biogeographic patterns and evolutionary processes. This study investigates the evolutionary history of the diving beetle subfamily Lancetinae through a phylogenomic approach incorporating ultraconserved elements (UCEs) and heritage genetic markers. Our findings support an early Miocene origin for Lancetinae, with subsequent diversification influenced by historical vicariance events and long-distance dispersal.
