Methods: Participants were adult key informants with expertise in food/nutrition and health within Tribal communities (N = 58) across the US. Data were collected through 1:1 interviews using a semistructured moderator guide and analyzed using thematic content analysis methods.

Protection against fibrosis by a bacterial consortium in metabolic dysfunction-associated steatohepatitis and the role of amino acid metabolism.

The gut microbiota drives progression to liver fibrosis, the main determinant of mortality in metabolic dysfunction-associated steatohepatitis (MASH). In this study, we aimed to identify bacterial species associated with protection against liver fibrosis in a high-risk population, and test their potential to protect against liver fibrosis . Based on stool shotgun metagenomic sequencing of 340 subjects from a population cohort disproportionally affected by MASH, we identified bacterial species from the and orders associated with reduced risk of liver fibrosis.

Stem cells tightly regulate dead cell clearance to maintain tissue fitness.

Billions of cells are eliminated daily from our bodies. Although macrophages and dendritic cells are dedicated to migrating and engulfing dying cells and debris, many epithelial and mesenchymal tissue cells can digest nearby apoptotic corpses. How these non-motile, non-professional phagocytes sense and eliminate dying cells while maintaining their normal tissue functions is unclear.

Learning from Tomorrow's Recyclers: Extension of Hands-on Recycled Waste Activity.

We previously developed a plastic sorting activity for high school students. In that activity, several tools were provided to separate plastic waste materials based on their physical properties while considering the time and cost for each separation step. Here, we aimed to understand the impact of this activity on the awareness of and learning about plastic sorting in a younger age group (8 to 11 years old) and explored how parental involvement influenced students' interest in the topic.

Raedwoon: A leadership development program for direct care nurses in Saudi Arabia.

This study assessed the Raedwoon program, a 25-day nursing leadership course, using a quasi-experimental design. It found overall improvements in leadership and nursing competencies, except in the “Inspire a Shared Vision” practice and documentation skills.

The Associations Between Health-Related Knowledge and Health Beliefs Regarding Risk for Gestational Diabetes in American Indian and Alaska Native Female Adolescents and Young Adults at Risk for Gestational Diabetes and Their Female Caregivers: A Cross-Sectional Dyadic Analysis.

Introduction: Research on associations between knowledge and health beliefs for women at risk for gestational diabetes mellitus (GDM) has focused on adults at risk for or having GDM. Gaps also exist in examining interpersonal associations with family members or peers. We examined dyadic associations between knowledge and health beliefs about the risk for GDM between and within American Indian and Alaska Native (AIAN) female adolescents and young adults (FAYAs) at risk for GDM and their mothers or adult female caregivers (FCs).

Decision-Making Engagement Preferences among Older Adults with CKD.

Key Points: Clinicians’ uncertainty about the degree to which older patients prefer to engage in decision making remains a key barrier to shared decision making. Most older adults with advanced CKD preferred a collaborative or active role in decision making.

Background: Older adults with kidney failure face preference-sensitive decisions regarding dialysis initiation.

Aberrant Lipid Metabolism in Macrophages Is Associated with Granuloma Formation in Sarcoidosis.

Chronic sarcoidosis is a complex granulomatous disease with limited treatment options that can progress over time. Understanding the molecular pathways contributing to disease would aid in new therapeutic development. To understand whether macrophages from patients with nonresolving chronic sarcoidosis are predisposed to macrophage aggregation and granuloma formation and whether modulation of the underlying molecular pathways influence sarcoidosis granuloma formation.

"You don't know what you don't know": A qualitative study of informational needs of patients, family members, and living donors to inform transplant system metrics.

Introduction: Informational needs and potential use of transplant metrics, especially among patients, remain understudied and a critical component of the transplant community's commitment to patient-centered care. We sought to understand the perspectives and needs of patients, family members/caregivers, living donors, and deceased donor family members.

Methods: We examined decision-making experiences and perspectives on the needs of these stakeholder groups for data about the national transplant system among 58 participants of 14 focus groups and 6 interviews.

Metabolic support by macrophages sustains colonic epithelial homeostasis.

The intestinal epithelium has a high turnover rate and constantly renews itself through proliferation of intestinal crypt cells, which depends on insufficiently characterized signals from the microenvironment. Here, we showed that colonic macrophages were located directly adjacent to epithelial crypt cells in mice, where they metabolically supported epithelial cell proliferation in an mTORC1-dependent manner. Specifically, deletion of tuberous sclerosis complex 2 (Tsc2) in macrophages activated mTORC1 signaling that protected against colitis-induced intestinal damage and induced the synthesis of the polyamines spermidine and spermine.

Gender Differences in a Mouse Model of Hepatocellular Carcinoma Revealed Using Multi-Modal Imaging.

The worldwide incidence of hepatocellular carcinoma (HCC) continues to rise, in part due to poor diet, limited exercise, and alcohol abuse. Numerous studies have suggested that the loss or mutation of PTEN plays a critical role in HCC tumorigenesis through the activation of the PI3K/Akt signaling axis. The homozygous knockout of PTEN in the livers of mice results in the accumulation of fat (steatosis), inflammation, fibrosis, and eventually progression to HCC.

Respecting tribal voices in the development of a gestational diabetes risk reduction preconception counseling program for American Indian/Alaska Native adolescent females: a qualitative study.

Background: American Indians and Alaska Natives (AI/AN) are disproportionately affected by adolescent obesity, adolescent pregnancy and gestational diabetes mellitus (GDM). GDM is associated with increased risk for perinatal death, obesity, and subsequent type 2 diabetes (T2D) for the offspring. Moreover, mothers with GDM are also at increased risk for T2D post-partum.

Progesterone Analysis in Canine Breeding Management.

Progesterone is a worthwhile addition to the clinical assessment of cycle stage for breeding, elective cesarian delivery, and reproductive management in the bitch if reliably measured. Clinical decisions based on systemic progesterone concentrations also require the rapid return of results. Most commercially accessible analyses capable of returning results within a day still rely primarily on immunoassays of one kind or another.

JAK/STAT as a Potential Therapeutic Target for Osteolytic Diseases.

Several cytokines with major biological functions in inflammatory diseases exert their functions through the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signal transduction pathway. JAKs phosphorylate the cytoplasmic domain of the receptor, inducing the activation of its substrates, mainly the proteins known as STATs. STATs bind to these phosphorylated tyrosine residues and translocate from the cytoplasm to the nucleus, further regulating the transcription of several genes that regulate the inflammatory response.

A biologist's guide to planning and performing quantitative bioimaging experiments.

Technological advancements in biology and microscopy have empowered a transition from bioimaging as an observational method to a quantitative one. However, as biologists are adopting quantitative bioimaging and these experiments become more complex, researchers need additional expertise to carry out this work in a rigorous and reproducible manner. This Essay provides a navigational guide for experimental biologists to aid understanding of quantitative bioimaging from sample preparation through to image acquisition, image analysis, and data interpretation.

Carbon Quantum Dots Based on Marine Polysaccharides: Types, Synthesis, and Applications.

The marine environment offers a vast array of resources, including plants, animals, and microorganisms, that can be utilized to extract polysaccharides such as alginate, carrageenan, chitin, chitosan, agarose, ulvan, porphyra, and many more. These polysaccharides found in marine environments can serve as carbon-rich precursors for synthesizing carbon quantum dots (CQDs). Marine polysaccharides have a distinct advantage over other CQD precursors because they contain multiple heteroatoms, including nitrogen (N), sulfur (S), and oxygen (O).

Comparing American Indian/Alaska Native Adolescent Daughters' and Their Mothers' Awareness, Knowledge, Attitudes, and Behaviors Regarding Risk for Gestational Diabetes: Implications for Mother-Daughter Communication on Reproductive Health.

Purpose: The purpose of the study was to describe, compare, and examine associations at baseline of reproductive health awareness, knowledge, health beliefs, communication and behaviors related to gestational diabetes (GDM) and GDM risk reduction in a vulnerable population of both American Indian/Alaska Native (AIAN) adolescent girls and their mothers.

Methods: Descriptive/comparative/correlational analyses examined multitribal baseline data on 149 mother-daughter (M-D) dyads (N = 298; daughter age = 12-24 years) enrolled in a longitudinal study to adapt and evaluate a culturally relevant diabetes preconception counseling (PC) program (Stopping-GDM). The associations between GDM risk reduction awareness, knowledge, health beliefs, and behaviors (eg, daughters' eating, physical activity, reproductive-health [RH] choices/planning, M-D communication, daughters' discussions on PC) were examined.

Stem cells tightly regulate dead cell clearance to maintain tissue fitness.

Macrophages and dendritic cells have long been appreciated for their ability to migrate to and engulf dying cells and debris, including some of the billions of cells that are naturally eliminated from our body daily. However, a substantial number of these dying cells are cleared by 'non-professional phagocytes', local epithelial cells that are critical to organismal fitness. How non-professional phagocytes sense and digest nearby apoptotic corpses while still performing their normal tissue functions is unclear.

A tissue injury sensing and repair pathway distinct from host pathogen defense.

Pathogen infection and tissue injury are universal insults that disrupt homeostasis. Innate immunity senses microbial infections and induces cytokines/chemokines to activate resistance mechanisms. Here, we show that, in contrast to most pathogen-induced cytokines, interleukin-24 (IL-24) is predominately induced by barrier epithelial progenitors after tissue injury and is independent of microbiome or adaptive immunity.

The Experiences of American Indian Participants and Site Coordinators in a Gestational Diabetes Risk Reduction Trial.

Gestational diabetes mellitus is the most common complication of pregnancy and contributes to increased risk for type 2 diabetes in both the mother and offspring. We developed and evaluated a gestational diabetes risk reduction and preconception counseling program, (SGDM), for American Indian females. The purpose of this study is to examine the experiences of American Indian mother-daughter dyad participants and the site coordinators who facilitated the SGDM randomized controlled trial to inform program revisions.

Duodenal macrophages control dietary iron absorption via local degradation of transferrin.

Iron is an essential cellular metal that is important for many physiological functions including erythropoiesis and host defense. It is absorbed from the diet in the duodenum and loaded onto transferrin (Tf), the main iron transport protein. Inefficient dietary iron uptake promotes many diseases, but mechanisms regulating iron absorption remain poorly understood.
