Effect of exercise interventions on cognitive function in breast cancer patients and survivors: a systematic review with meta-analysis.

Background: Exercise has been shown to facilitate cognitive function; however, data on changes in cognitive function in response to exercise interventions among breast cancer patients and survivors, who frequently experience cognitive impairment, have not been comprehensively synthesized. Therefore, this study aims to examine the impact of exercise interventions on cognitive function among breast cancer patients and survivors.

Methods: Electronic databases including PubMed, Scopus, and Web of Science were searched from inception to December 25, 2024.

Founders Can Increase Determinism of Community Assembly.

The effect of founders (the potential influence of initially colonizing species on the composition, functionality, and stability of communities) plays a crucial role in community assembly; many experimental studies on priority effects or artificially assembled species have suggested the existence of this effect, but direct experimental evidence at the community level remains limited. This study used sterilized and nonsterilized paocai soup (a traditional Chinese fermented vegetable soup) from the same source to simulate initial environments with and without founders. These were placed in beakers with varying opening sizes on an open rooftop for 15 days to explore the impact of founders on community assembly under different dispersal intensities.

Age-related change of glymphatic function in normative children assessed using diffusion tensor imaging-analysis along the perivascular space.

Background: The glymphatic system, crucial for brain waste removal and homeostasis, has an underexplored developmental trajectory in children. This study describes changes in glymphatic function during childhood via diffusion tensor imaging-analysis along the perivascular space (DTI-ALPS).

Methods: We retrospectively studied DTI MR images of 72 pediatric participants (mean age = 92.

Acute effects of resistance exercise intensity and repetition at a predetermined volume on inhibitory control: a randomized controlled trial.

Background: This study explores the effects of acute resistance exercise (RE) on inhibitory control (IC), emphasizing exercise volume.

Methods: In total, 78 young adults were randomly assigned to one of three groups: the moderate-intensity group [MI; 60% one repetition maximum (1RM), 3 × 10 reps], the low-intensity group (LI; 30% 1RM, 3 × 20 reps), or the control group (CON; 35 min reading). The exercise groups were volume-matched.

Interpreting Microbial Species-Area Relationships: Effects of Sequence Data Processing Algorithms and Fitting Models.

In the study of Species-Area Relationships (SARs) in microorganisms, outcome discrepancies primarily stem from divergent high-throughput sequencing data processing algorithms and their combinations with different fitting models. This paper investigates the impacts and underlying causes of using diverse sequence data processing algorithms in microbial SAR studies, as well as compatibility issues that arise between different algorithms and fitting models. The findings indicate that the balancing strategies employed by different algorithms can result in variations in the calculations of alpha and beta diversity, thereby influencing the SARs of microorganisms.

Secular Trends in the Incidence of Encephalitis and Outcomes of Postencephalitic Epilepsy in Taiwan: A Nationwide Population-Based Study.

Background: Encephalitis can lead to significant disability among survivors. Up-to-date estimates of encephalitis incidence and the risk of postencephalitic epilepsy (PE) are crucial for informing health policy.

Methods: We used the National Taiwan Insurance Research Database to estimate the standardized incidence of encephalitis for each year from 2003 to 2017.

Acute Concurrent Exercise Improves Inhibitory Control Without Mediating the Role of Lactate: An Event-Related Potential Study.

Background: Concurrent exercise (CE), an emerging exercise modality characterized by sequential bouts of aerobic (AE) and resistance exercise (RE), has demonstrated acute benefits on executive functions (EFs) and neuroelectric P3 amplitude. However, the effect of acute CE on inhibitory control, a sub-component of EFs, and P3 amplitude remains inconclusive. Moreover, exploring the mechanisms underlying the effects of acute exercise on EFs contributes to scientific comprehension, with lactate recognized as a crucial candidate positively correlated with EFs.

Sex-specific astrocyte regulation of spinal motor circuits by Nkx6.1.

Astrocytes exhibit diverse cellular and molecular properties across the central nervous system (CNS). Recent studies identified region-specific transcription factors (TF) that oversee these diverse properties; how sex differences intersect with region-specific transcriptional programs to regulate astrocyte function is unknown. Here, we show that the TF Nkx6.

Remote neuronal activity drives glioma progression through SEMA4F.

The tumour microenvironment plays an essential role in malignancy, and neurons have emerged as a key component of the tumour microenvironment that promotes tumourigenesis across a host of cancers. Recent studies on glioblastoma (GBM) highlight bidirectional signalling between tumours and neurons that propagates a vicious cycle of proliferation, synaptic integration and brain hyperactivity; however, the identity of neuronal subtypes and tumour subpopulations driving this phenomenon is incompletely understood. Here we show that callosal projection neurons located in the hemisphere contralateral to primary GBM tumours promote progression and widespread infiltration.

Induction of astrocytic Slc22a3 regulates sensory processing through histone serotonylation.

Neuronal activity drives alterations in gene expression within neurons, yet how it directs transcriptional and epigenomic changes in neighboring astrocytes in functioning circuits is unknown. We found that neuronal activity induces widespread transcriptional up-regulation and down-regulation in astrocytes, highlighted by the identification of as an activity-inducible astrocyte gene that encodes neuromodulator transporter Slc22a3 and regulates sensory processing in the mouse olfactory bulb. Loss of astrocytic Slc22a3 reduced serotonin levels in astrocytes, leading to alterations in histone serotonylation.

Inhibitory input directs astrocyte morphogenesis through glial GABAR.

Communication between neurons and glia has an important role in establishing and maintaining higher-order brain function. Astrocytes are endowed with complex morphologies, placing their peripheral processes in close proximity to neuronal synapses and directly contributing to their regulation of brain circuits. Recent studies have shown that excitatory neuronal activity promotes oligodendrocyte differentiation; whether inhibitory neurotransmission regulates astrocyte morphogenesis during development is unclear.

Remote neuronal activity drives glioma infiltration via Sema4f.

The tumor microenvironment (TME) plays an essential role in malignancy and neurons have emerged as a key component of the TME that promotes tumorigenesis across a host of cancers. Recent studies on glioblastoma (GBM) highlight bi-directional signaling between tumors and neurons that propagates a vicious cycle of proliferation, synaptic integration, and brain hyperactivity; however, the identity of neuronal subtypes and tumor subpopulations driving this phenomenon are incompletely understood. Here we show that callosal projection neurons located in the hemisphere contralateral to primary GBM tumors promote progression and widespread infiltration.

Activity-dependent induction of astrocytic Slc22a3 regulates sensory processing through histone serotonylation.

Neuronal activity drives global alterations in gene expression within neurons, yet how it directs transcriptional and epigenomic changes in neighboring astrocytes in functioning circuits is unknown. Here we show that neuronal activity induces widespread transcriptional upregulation and downregulation in astrocytes, highlighted by the identification of a neuromodulator transporter Slc22a3 as an activity-inducible astrocyte gene regulating sensory processing in the olfactory bulb. Loss of astrocytic Slc22a3 reduces serotonin levels in astrocytes, leading to alterations in histone serotonylation.

Social deprivation induces astrocytic TRPA1-GABA suppression of hippocampal circuits.

Social experience is essential for the development and maintenance of higher-order brain function. Social deprivation results in a host of cognitive deficits, and cellular studies have largely focused on associated neuronal dysregulation; how astrocyte function is impacted by social deprivation is unknown. Here, we show that hippocampal astrocytes from juvenile mice subjected to social isolation exhibit increased Ca activity and global changes in gene expression.

Passive sampling hypothesis did not shape microbial species-area relationships in open microcosm systems.

The passive sampling hypothesis is one of the most important hypotheses used to explain the mechanism of species-area relationships (SAR) formation. This hypothesis has not yet been experimentally validated due to the confusion between passive sampling (a larger area may support more colonists when fully sampled) and sampling effects (more sampling effort will result in increased species richness when sampling is partial). In this study, we created an open microcosm system with homogeneous habitat, consistent total resources, and biodiversity background using Chinese paocai soup, a fermented vegetable, as a substrate.

Chronic exposure to carbon black ultrafine particles reprograms macrophage metabolism and accelerates lung cancer.

Chronic exposure to airborne carbon black ultrafine (nCB) particles generated from incomplete combustion of organic matter drives IL-17A-dependent emphysema. However, whether and how they alter the immune responses to lung cancer remains unknown. Here, we show that exposure to nCB particles increased PD-L1 PD-L2 CD206 antigen-presenting cells (APCs), exhausted T cells, and T cells.

Measuring Roadway Lane Widths Using Connected Vehicle Sensor Data.

The United States has over three trillion vehicle miles of travel annually on over four million miles of public roadways, which require regular maintenance. To maintain and improve these facilities, agencies often temporarily close lanes, reconfigure lane geometry, or completely close the road depending on the scope of the construction project. Lane widths of less than 11 feet in construction zones can impact highway capacity and crash rates.

A Synchrotron Radiation Photoemission Study of SiGe(001)-2×1 Grown on Ge and Si Substrates: The Surface Electronic Structure for Various Ge Concentrations.

Beyond the macroscopic perspective, this study microscopically investigates SiGe(001)-2×1 samples that were grown on the Ge(001) and Si(001) substrates via molecular-beam epitaxy, using the high-resolution synchrotron radiation photoelectron spectroscopy (SRPES) as a probe. The low-energy electron diffraction equipped in the SRPES chamber showed 2×1 double-domain reconstruction. Analyses of the Ge 3d core-level spectra acquired using different photon energies and emission angles consistently reveal the ordered spots to be in a Ge-Ge tilted configuration, which is similar to that in Ge(001)-2×1.

Sculpting Astrocyte Diversity through Circuits and Transcription.

Astrocytes are the most abundant glial cell in the central nervous system and occupy a wide range of roles that are essential for brain function. Over the past few years, evidence has emerged that astrocytes exhibit cellular and molecular heterogeneity, raising the possibility that subsets of astrocytes are functionally distinct and that transcriptional mechanisms are involved in encoding this prospective diversity. In this review, we focus on three emerging areas of astrocyte biology: region-specific circuit regulation, molecular diversity, and transcriptional regulation.

Kawasaki Shock Syndrome with Initial Presentation as Neck lymphadenitis: A Case Report.

Kawasaki disease (KD) is an acute systemic vasculitis of unknown cause that mainly affects infants and children and can result in coronary artery complications if left untreated. A small subset of KD patients with fever and cervical lymphadenitis has been reported as node-first-presenting KD (NFKD). This type of KD commonly affects the older pediatric population with a more intense inflammatory process.
