Do empirically-derived personality subtypes relate to cognitive inflexibility in anorexia nervosa and bulimia nervosa?

Background: Accruing evidence suggests that personality-based approaches to eating disorder classification may offer several advantages over current diagnostic models, with prior research consistently identifying three personality-based groups characterized by either (1) high levels of impulsivity and dysregulation (termed the "undercontrolled" group), (2) high levels of rigidity and avoidance (termed the "overcontrolled" group), or (3) relatively normative levels of personality functioning (termed the "low psychopathology" group). Cognitive inflexibility (i.e.

The role of MAPK pathway in gastric cancer: unveiling molecular crosstalk and therapeutic prospects.

Gastric cancer remains a significant health burden globally, especially prevalent in Asian and European regions. Despite a notable decline in incidence in the United States and Western Europe over recent decades, the disease's persistence underscores the urgency for advanced research in its pathogenesis and treatment strategies. Central to this pursuit is the exploration of the mitogen-activated protein kinase (MAPK) pathway, a pivotal cellular mechanism implicated in the complex processes of gastric cancer development, including cellular proliferation, invasion, migration, and metastasis.

Social, environmental, and developmental factors affect the microbiota of barn owls (Tyto alba) in a cross-fostering experiment.

Background: Species host diverse microbial communities that can impact their digestion and health, which has led to much interest in understanding the factors that influence their microbiota. We studied the developmental, environmental, and social factors that influence the microbiota of nestling barn owls (Tyto alba) through a partial cross-fostering experiment that manipulated the social and nest environment of the nestlings. We then examined the nestling microbiota before and three weeks after the exchange of nestlings between nests, along with the microbiota of the adults at the nest and nestlings in unmanipulated nests.

Association between the female hormone intake and cardiovascular disease in the women: a study based on NHANES 1999-2020.

Although many studies have reported the relationship between female hormone intake and cardiovascular disease (CVD) development, their association has not been fully elucidated and defined, based on data from the Third National Health and Nutrition Examination Survey intending to assess the health and nutritional status of non-institutionalized children and adults in the United States. This study examined the relationship between female hormone intake and coronary artery disease (CVD) development in 38,745 women, averaging 38.10 ± 12.

California mice (Peromyscus californicus) adjust mouth movements for vocal production during early postnatal development.

Background: The order Rodentia is the largest group of mammals. Diversification of vocal communication has contributed to rodent radiation and allowed them to occupy diverse habitats and adopt different social systems. The mechanism by which efficient vocal sounds, which carry over surprisingly large distances, are generated is incompletely understood.

Mpox mRNA-1769 vaccine inhibits orthopoxvirus replication at intranasal, intrarectal, and cutaneous sites of inoculation.

We previously reported that mice immunized twice with a lipid nanoparticle vaccine comprising four monkeypox viral mRNAs raised neutralizing antibodies and antigen-specific T cells and were protected against a lethal intranasal challenge with vaccinia virus (VACV). Here we demonstrated that the mRNA vaccine also protects mice against intranasal and intraperitoneal infections with monkeypox virus and bioluminescence imaging showed that vaccination greatly reduces or prevents VACV replication and spread from intranasal, rectal, and dermal inoculation sites. A single vaccination provided considerable protection that was enhanced by boosting for at least 4 months.

Introduction/aims: Skeletal muscle magnetic resonance imaging (MRI) is a validated noninvasive tool to assess Duchenne muscular dystrophy (DMD) progression. There is interest in finding DMD biomarkers that decrease the burden of clinical trial participation, such as wearable devices. Our aim was to evaluate the relationship between activity, via accelerometry, and skeletal muscle MRI, particularly T mapping.

Force-Responsive Delivery of Anticancer Drugs via a DNA Mechanical Nanovehicle.

Cellular mechanical dysregulation can lead to diseases and conditions like tumorigenesis. Drug delivery systems that recognize and respond to specific cellular mechanical characteristics are potentially useful for targeted therapy. We report here the creation of a DNA mechanical nanovehicle that is responsive to cell surface receptor-mediated tensile forces, which can then correspondingly deliver an anticancer drug in situ.

Gaps in the Assessment and Care of Neurodevelopmental and Psychiatric Conditions Associated With Dystrophinopathy.

Introduction/aims: While dystrophinopathies are primarily characterized by progressive muscle weakness with onset during childhood, dystrophin also plays a role in brain development. This study aimed to characterize how neurodevelopmental and psychiatric disorders are currently identified and managed in clinical care of those with Becker and Duchenne muscular dystrophy (BDMD).

Methods: Parent Project Muscular Dystrophy (PPMD) disseminated surveys to caregivers and health care providers (HCPs) in the United States to assess the frequency and management of neurodevelopmental and psychiatric disorders of those with dystrophinopathy.

Deliveries were assigned SDI scores based on preconception zip code.

The "Mammograms Available Due to Resources and Education" (MADRE) Study: Rationale and Design.

Background: Latinas suffer disproportionately from breast cancer, partially due to lower uptake of guideline-concordant breast cancer screening. We describe the design of a study to compare two approaches addressing this important public health problem.

Design/methods: We are conducting a 5-year randomized controlled trial.

Labeling and isolating cell specific neuronal mitochondria and their functional analysis in mice post stroke.

Dendritic and axonal plasticity, which mediates neurobiological recovery after a stroke, critically depends on the mitochondrial function of neurons. To investigate, in vivo, neuronal mitochondrial function at the stroke recovery stage, we employed Mito-tag mice combined with cerebral cortical infection of AAV9 produced from plasmids carrying Cre-recombinase controlled by two neuronal promoters, synapsin-I (SYN1) and calmodulin-kinase IIa to induce expression of a hemagglutinin (HA)-tagged enhanced green fluorescence protein (EGFP) that localizes to mitochondrial outer membranes of SYN1 positive (SYN) and CaMKIIa positive (CaMKIIa) neurons. These mice were then subjected to permanent middle cerebral artery occlusion (MCAO) and sacrificed 14 days post stroke.

Globular-shaped Aβ oligomers have diverse mechanisms for promoting Aβ aggregations with the facilitation of fibril elongation.

The accumulation of amyloid β-proteins (Aβ) in the extracellular space, forming insoluble plaques, is a primary pathological process underlying Alzheimer's disease (AD). Among the various Aβ species that appear during Aβ aggregation, Aβ oligomers are considered the most neurotoxic form. However, the precise mechanisms of their molecular functions within the Aβ aggregation cascade have not been clarified so far.

Biased signaling in GPCRs: Structural insights and implications for drug development.

G protein-coupled receptors (GPCRs) are the largest family of cell surface receptors in humans, playing a crucial role in regulating diverse cellular processes and serving as primary drug targets. Traditional drug design has primarily focused on ligands that uniformly activate or inhibit GPCRs. However, the concept of biased agonism-where ligands selectively stabilize distinct receptor conformations, leading to unique signaling outcomes-has introduced a paradigm shift in therapeutic development.

Biased agonism at free-fatty acid receptor-4 (FFA4/GPR120).

Free-fatty acid receptor-4 (FFA4), previously known as GPR120, is a G protein-coupled receptor (GPCR) activated by medium-to-long chain free fatty acids (FFAs), including saturated, monounsaturated, and polyunsaturated fats, many of which (e.g., omega-3 fatty acids) are critical contributors to human health and disease.

Poststroke hyperglycemia dysregulates cap-dependent translation in neural cells.

Aims: Post stroke hyperglycemia has been shown to deter functional recovery. Earlier findings have indicated the cap-dependent translation regulator 4E-BP1 is detrimentally upregulated in hyperglycemic conditions. The present study aims to test the hypothesis that hyperglycemic ischemic reperfusion injury (I/R) affects normal protein translation poststroke.
