Global and local origins of trial-to-trial spike count variability in visual cortex.

Sensory neuron spiking responses vary across repeated presentations of the same stimuli, but whether this trial-to-trial variability represents noise versus unidentified signals remains unresolved. Some of the variability can be attributed to correlations between neural activity and arousal, locomotion, and other overt movements. We hypothesized that correlations with global activity factors, i.

Cell type-specific contributions to impaired blood-brain barrier and cerebral metabolism in presymptomatic 5XFAD mice.

Altered cerebral metabolism and blood-brain barrier (BBB) dysfunction are emerging as critical contributors to the preclinical phase of Alzheimer's disease (AD), underscoring their role in early pathogenesis. To identify sensitive biomarkers before irreversible neuronal loss and cognitive decline, we examined 5XFAD mice at 3 months of age by applying multiple advanced MRI techniques. Arterial spin tagging based MRI revealed increased BBB permeability and water extraction fraction, indicating compromised BBB integrity at the early stage of pathogenesis in 5×FAD mice.

Validity evidence of the Social, Academic, and Emotional Behavior Risk Screener - Teacher Rating Scale: A systematic review & quantitative synthesis.

Early identification of student social, emotional, and behavioral (SEB) concerns is vital to prevent and ameliorate future difficulties. Yet, assessment practices rely on sound validity arguments to accurately identify students who may benefit from support. As the strength of a validity argument relies on the extent of validity evidence, the synthesis of evidence may facilitate appropriate use and interpretation.

Translational strategies for oral delivery of faecal microbiota transplantation.

Faecal microbiota transplantation (FMT) has emerged as a transformative therapy for infections and shows promise for various GI and systemic diseases. However, the poor patient acceptability and accessibility of 'conventional' FMT, typically administered via colonoscopies or enemas, hinders its widespread clinical adoption, particularly for chronic conditions. Oral administration of FMT (OralFMT) overcomes these limitations, yet faces distinct challenges, including a significant capsule burden, palatability concerns and poor microbial viability during gastric transit.

Neutrophil extracellular traps aggravate placental injury in OAPS by facilitating activation of BNIP3 mediated mitophagy.

Obstetric antiphospholipid syndrome (OAPS) is an autoimmune disease mediated by antiphospholipid antibodies (aPL), characterized by miscarriage, pre-mature birth caused by pre-eclampsia, intrauterine growth restriction, and other pregnancy complications. Neutrophil extracellular traps (NETs) consist of chromatin scaffolds coated with histones, proteases, granules, and cytosolic proteins. Here, we have observed increased levels of NETs in both human OAPS placental tissues and animal models, accompanied by apoptosis increases.

Gestational Exposure to Black Phosphorus Nanoparticles Induces Placental Trophoblast Dysfunction by Triggering Reactive Oxygen Species-Regulated Mitophagy.

As a type of two-dimensional nanomaterial, black phosphorus (BP) has attracted considerable interest for applications in various fields. Despite its advantages, including biodegradability and biocompatibility, recent studies have shown that BP exhibits cytotoxicity in different types of cells. However, no studies have investigated the effects of BP exposure during pregnancy.

Structures of the human adult muscle-type nicotinic receptor in resting and desensitized states.

Muscle-type nicotinic acetylcholine receptor (AChR) is the key signaling molecule in neuromuscular junctions. Here, we present the structures of full-length human adult receptors in complex with Fab35 in α-bungarotoxin (αBuTx)-bound resting states and ACh-bound desensitized states. In addition to identifying the conformational changes during recovery from desensitization, we also used electrophysiology to probe the effects of eight previously unstudied AChR genetic variants found in patients with congenital myasthenic syndrome (CMS), revealing they cause either slow- or fast-channel CMS characterized by prolonged or abbreviated ion channel bursts.

Introduction: Preeclampsia (PE) is a hypertensive disorder of pregnancy characterized by pronounced placental oxidative stress and inflammatory damage. However, the contribution of mitophagy to inflammation-induced placental injury in PE remains unclear.

Methods: Human placenta samples were collected from 15 normal pregnant women and 15 preeclampsia pregnant women.

A study protocol for a double-blinded, randomised, placebo-controlled trial on the use of encapsulated FMT for reducing the side effects of HSCT: the HSCT-BIOME study.

Background: The composition of the gut microbiota both prior to and after haematopoietic stem cell transplantation (HSCT) is increasingly implicated in the outcomes of HSCT, including infections, poor immune reconstitution and disease relapse. Faecal microbiota transplantation (FMT) offers a potential strategy of supporting the gut microbiota and improve HSCT outcomes. Although FMT has been investigated in HSCT recipients, it has largely been evaluated therapeutically for indications such as infection, or once immunocompetency is regained.

EAAT3 modulation: A potential novel avenue towards remyelination in multiple sclerosis.

Modulating the excitatory amino acid transporter 3 (EAAT3) can be considered a novel approach for the treatment of multiple sclerosis (MS). EAAT3 plays a crucial role in regulating oxidative stress and oligodendrocyte function through its ability to transport cysteine, the rate-limiting building block in the synthesis of the antioxidant glutathione. Therefore, EAAT3 activation is hypothesised to improve oligodendrocyte health and relieve its differentiation block in MS, improving remyelination capacity.

Spatial histomorphometry reveals that local peripheral nerves modulate but are not required for skeletal adaptation to applied load in mice.

Mechanical loading is required for bone health and results in skeletal adaptation to optimize strength. Local nerve axons, particularly within the periosteum, may respond to load-induced biomechanical and biochemical cues. However, their role in the bone anabolic response remains controversial.

Proteomic profiling of kidney biopsies in nephrotic syndrome.

Background: Minimal change disease (MCD) and focal segmental glomerulosclerosis (FSGS) are patterns of kidney injury observed in the filtering units of the kidney known as glomeruli. These histological patterns are seen in kidney biopsies from individuals with idiopathic nephrotic syndrome (iNS), which occurs in both children and adults. However, there is some indication that MCD and FSGS are within the same phenotypic spectrum.

Regenerative Potential Nanomedicine of Adipocyte Stem Cell-Derived Exosomes in Senescent Skin Tissue.

Introduction: Skin is the first-line barrier defense against infection, irradiation, and toxins, but is prone to natural aging (intrinsic aging) and environmental factors (extrinsic aging). Hence, there is an increasing urgency to explore an effective treatment for aging skin. This study was focused on testing the potential of utilizing adipocyte stem cell derived exosomal as nanomedicine to regenerate the dermal layer and counteract signs of skin aging.

Simultaneous mesoscopic measurement and manipulation of mouse cortical activity.

Dynamics of activity across the cerebral cortex at the mesoscopic scale - coordinated fluctuations of local populations of neurons - are essential to perception and cognition and relevant to computations like sensorimotor integration and goal-directed task engagement. However, understanding direct causal links between population dynamics and behavior requires the ability to manipulate mesoscale activity and observe the effect of manipulation across multiple brain regions simultaneously. Here, we develop a novel system enabling simultaneous recording and manipulation of activity across the dorsal cortex of awake mice, compatible with large-scale electrophysiology from any region across the brain.
