Constructing a metadata knowledge graph as an atlas for demystifying AI pipeline optimization.

The emergence of advanced artificial intelligence (AI) models has driven the development of frameworks and approaches that focus on automating model training and hyperparameter tuning of end-to-end AI pipelines. However, other crucial stages of these pipelines such as dataset selection, feature engineering, and model optimization for deployment have received less attention. Improving efficiency of end-to-end AI pipelines requires metadata of past executions of AI pipelines and all their stages.

Age-stratified trends and outcomes of inpatient cholecystectomy for acute cholecystitis in the United States.

Background: The elderly population in the United States is rapidly expanding. Older patients over age 65 with acute cholecystitis may face greater perioperative risk compared to younger patients undergoing urgent laparoscopic cholecystectomy. We aimed to characterize trends in utilization and outcomes of inpatient cholecystectomy across the United States stratified by age.

Microphysiological system to address the opioid crisis: A novel multi-organ model of acute opioid overdose and recovery.

Opioids have been the primary method used to manage pain for hundreds of years, however the increasing prescription rate of these drugs in the modern world has led to a public health crisis of overdose related deaths. Naloxone is the current standard treatment for opioid overdose rescue, but it has not been fully investigated for potential off-target toxicity effects. The current methods for pharmaceutical development do not correlate well with pre-clinical animal studies compared to clinical results, creating a need for improved methods for therapeutic evaluation.

The role of anti-inflammatory diets and supplementation in metabolic syndrome and symptom remission in adults with schizophrenia: a systematic review.

Introduction: Immune dysregulation and chronic inflammation have been hypothesized as potential pathways in metabolic syndrome and schizophrenia. Anti-inflammatory diets have the potential not only to treat metabolic syndrome but also to reduce the symptom burden in schizophrenia. The aim of this systematic review was to investigate the role of anti-inflammatory diets and vitamin supplementation in the management of metabolic syndrome and in symptom remission in people with schizophrenia.

Ayahuasca-assisted meaning reconstruction therapy for grief: a non-randomized clinical trial protocol.

Background: Psychotherapy for Prolonged Grief Disorder (PGD), a condition characterized by an intense and persistent grief response, has received increased attention over the past decades. Evidence-based approaches to prevent PGD are currently scarce, and not always effective. This paper introduces a protocol for a clinical trial exploring the effectiveness of a Meaning Reconstruction psychotherapy approach (MR) assisted with ayahuasca, a traditional indigenous medicine.

Poor self-reported sleep is associated with prolonged white matter T2 relaxation in psychotic disorders.

Background: Psychotic disorders are characterized by white matter (WM) abnormalities; however, their relationship with the various aspects of illness presentation remains unclear. Sleep disturbances are common in psychosis, and emerging evidence suggests that sleep plays a critical role in WM physiology. Therefore, it is plausible that sleep disturbances are associated with impaired WM integrity in these disorders.

Developing a translational research framework for MDD: combining biomolecular mechanisms with a spiraling risk factor model.

Objective: The global incidence and burden of Major Depressive Disorder (MDD) are increasing annually, with current antidepressant treatments proving ineffective for 30-40% of patients. Biomolecular mechanisms within the microbiota-gut-brain axis (MGBA) may significantly contribute to MDD, potentially paving the way for novel treatment approaches. However, integrating the MGBA with the psychological and environmental aspects of MDD remains challenging.

Effective semi-fed-batch saccharification with high lignocellulose loading using co-culture of and strain A9.

Maximizing saccharification efficiency of lignocellulose and minimizing the production costs associated with enzyme requirements are crucial for sustainable biofuel production. This study presents a novel semi-fed-batch saccharification method that uses a co-culture of and strain A9 to efficiently break down high solid-loading lignocellulosic biomass without the need for any external enzymes. This method optimizes saccharification efficiency and enhances glucose production from alkaline-treated rice straw, a representative lignocellulosic biomass.

Prolonged storage reduces viability of and core intestinal bacteria in fecal microbiota transplantation preparations for dogs.

Introduction: Fecal microbiota transplantation (FMT) has been described useful as an adjunct treatment for chronic enteropathy in dogs. Different protocols can be used to prepare and store FMT preparations, however, the effect of these methods on microbial viability is unknown. We aimed (1) to assess the viability of several core intestinal bacterial species by qPCR and (2) to assess () viability through culture to further characterize bacterial viability in different protocols for FMT preparations.

Complex bacterial diversity of Guaymas Basin hydrothermal sediments revealed by synthetic long-read sequencing (LoopSeq).

Hydrothermal sediments host phylogenetically diverse and physiologically complex microbial communities. Previous studies of microbial community structure in hydrothermal sediments have typically used short-read sequencing approaches. To improve on these approaches, we use LoopSeq, a high-throughput synthetic long-read sequencing method that has yielded promising results in analyses of microbial ecosystems, such as the human gut microbiome.

Epigenetic and epitranscriptomic regulation during oncogenic -herpesvirus infection.

Oncogenic gamma herpesviruses, including Epstein-Barr Virus (EBV) and Kaposi's Sarcoma-associated Herpesvirus (KSHV), are opportunistic cancer-causing viruses and induces oncogenesis through complex mechanisms, which involves manipulation of cellular physiology as well as epigenetic and epitranscriptomic reprogramming. In this review, we describe the intricate processes by which these viruses interact with the epigenetic machinery, leading to alterations in DNA methylation, histone modifications, and the involvement of non-coding RNAs. The key viral proteins such as EBNA1 and LMP1 encoded by EBV; LANA and vGPCR encoded by KSHV; play pivotal roles in these modifications by interacting with host factors, and dysregulating signaling pathways.

Fish gut microbiome and its application in aquaculture and biological conservation.

Understanding the diversity and function of fish gut microbiomes has advanced substantially, yet many aspects remain poorly understood, particularly the interplay among microbiota, host species, and environmental factors in the context of conservation. This review explores the composition and abundance of gut bacterial communities in key aquaculture fish groups-cyprinids, ictalurids (catfish), salmonids, and cichlids (tilapia)-alongside the model organism zebrafish, across diverse geographic regions. The findings highlight environmental habitats and host species as primary determinants of gut microbiome structure, offering a global perspective on these microbial communities.

Combined T1-weighted MRI and diffusion MRI tractography of paraventricular, locus coeruleus, and dorsal vagal complex connectivity in brainstem-hypothalamic nuclei.

Background: Current multimodal neuroimaging plays a critical role in studying clinical conditions such as cardiovascular disease, major depression, and other disorders related to chronic stress. These conditions involve the brainstem-hypothalamic network, specifically the locus coeruleus (LC), dorsal vagal complex (DVC), and paraventricular nucleus (PVN) of the hypothalamus, collectively referred to as the "DVC-LC-PVN circuitry." This circuitry is strongly associated with the norepinephrine (NE) and epinephrine (E) neurotransmitter systems, which are implicated in the regulation of key autonomic functions, such as cardiovascular and respiratory control, stress response, and cognitive and emotional behaviors.

Estimating financial and health burden by initial Medicare plan choice and history of cancer.

Understanding the downstream consequences of initial Medicare plan selection is necessary to ensure access to and affordability of health care services, especially for older adults with serious illness. We used 2008-2020 data from the Health and Retirement Study to estimate financial and health burden by initial Medicare plan selection (traditional Medicare without supplemental coverage, traditional Medicare plus supplemental coverage, or Medicare Advantage) and self-reported history of cancer. Initially choosing benefits with greater financial protections (either traditional Medicare plus supplemental coverage or Medicare Advantage) relative to traditional Medicare without supplemental coverage was associated with lower levels of out-of-pocket spending and a lower likelihood of reporting cost-related medication nonadherence and fair or poor health.

Sanctuary policies and type 2 diabetes medication prescription trends among community health center patients.

Immigrants in the United States are at increased risk of diabetes-related complications due to delayed diagnoses compared with US-born individuals. Immigration-related federal policies may support immigration enforcement activities and restrict some immigrants' access to health insurance and other publicly funded resources. Conversely, state and county-level sanctuary policies may reduce the fear of deportation and increase mobility in the community, improving the accessibility of essential pharmacological treatment for type 2 diabetes patients.

Changes in coverage stability and churning for private, individual insurance under the Affordable Care Act.

The Affordable Care Act (ACA) transformed the market for individual insurance. Using the 2-year panels of the Household Component of the Medical Expenditure Panel Survey covering the 2002-2022 period and controlling for the business cycle and other factors, we find the share of nonelderly adults enrolled in individual insurance doubled under the ACA. The percentage of adults covered by individual insurance 1-23 months more than doubled, and the percentage with at least 24 months rose 80% in states that did not expand Medicaid.

Characterization of an Unexpected μ Adsorption of Molecular Oxygen on Ag(100) with Low-Temperature STM.

Precise description of the interaction between molecular oxygen and metal surfaces is one of the most challenging topics in quantum chemistry. In this work, we use low-temperature scanning tunneling microscopy (STM) to identify and characterize an adsorption state of molecular oxygen that coordinates to three Ag atoms (μ) on Ag(100). Surprisingly, μ-O cannot be identified as a stable configuration with generalized gradient approximation (GGA)-level density functional theory (DFT) calculations.

Interfacial Properties of Gold and Cobalt Oxyhydroxide in Plasmon-Mediated Oxygen Evolution Reaction.

Water electrolysis is a green method of storing electrical energy in the chemical bonds of high-energy hydrogen gas (H). However, the anodic oxygen evolution reaction (OER) requires a significant kinetic overpotential, limiting the electrolysis rate. Recently, plasmonic gold nanoparticles (Au NPs) have been introduced to improve charge transfer at the interface between the OER electrocatalysts and the electrolyte under light illumination.
