Advancing Drug Development in Myelodysplastic Syndromes.

Myelodysplastic syndromes/neoplasms (MDS) are heterogeneous stem cell malignancies characterized by poor prognosis and no curative therapies outside of allogeneic hematopoietic stem cell transplantation. Despite some recent approvals by the United States Food and Drug Administration (FDA), (e.g.

Avian circoviruses and hepadnaviruses identified in tissue samples of various waterfowl.

North America is home to over 40 species of migratory waterfowl. Utilizing tissue and cloacal-swab sampling from hunter-harvested carcasses in 2021-2023, we identified circular DNA viruses associated with 116 waterfowl samples from nine species (American wigeons, Mexican ducks, northern shovelers, northern pintails, canvasbacks, mallards, American black ducks, gadwalls, and green-winged teals). We determined the genome sequences of viruses in the families Circoviridae (n = 18) and Hepadnaviridae (n = 2) from the 13 virus-infected birds.

Urinary Metal Levels, Cognitive Test Performance, and Dementia in the Multi-Ethnic Study of Atherosclerosis.

Importance: Metals are established neurotoxicants, but evidence of their association with cognitive performance at low chronic exposure levels is limited.

Objective: To investigate the association of urinary metal levels, individually and as a mixture, with cognitive tests and dementia diagnosis, including effect modification by apolipoprotein ε4 allele (APOE4).

Design, Setting, And Participants: The multicenter prospective cohort Multi-Ethnic Study of Atherosclerosis (MESA) was started from July 2000 to August 2002, with follow-up through 2018.

Implications for metabolic disturbances in myelodysplastic syndromes.

The Myelodysplastic Syndromes (MDS) are heterogeneous stem cell malignancies clinically characterized by bone marrow dysplasia, peripheral blood cytopenias, and a high risk for transformation to acute myeloid leukemia. In early stages of disease, differentiation defects and maturation blocks result in deficient hematopoiesis. In higher risk disease, unrestricted proliferation of immature blast cells leads to leukemogenesis.

Intestinal microbiome and myelodysplastic syndromes: Current state of knowledge and perspectives for future.

The intestinal microbiome has been mechanistically linked with health and many disease processes. Cancer is no exception. Both in solid tumors and hematologic malignancies, there is increasing evidence supporting the involvement of the intestinal microbiome in tumor development, disease progression, response to treatment, and treatment toxicity.

Patient-reported outcomes in early phase trials for patients with myelodysplastic syndromes.

Patients with myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML) experience a wide range of symptoms due both to their underlying disease and the effects of treatment. Designing early phase trials to explore effective therapies in these patients should not only examine anti-tumor activity, but also consider the effects of treatments on how patients feel and function. Assessing symptomatic toxicities associated with new therapies in early phase trials from the patient perspective is best measured using patient-reported outcomes (PROs) and offers valuable insight and complementary information to the traditional adverse event reporting in cancer clinical trials.

"Broadening Perspectives Activities" Improve LGBTQ+ Student Experiences and Religious Students' Content Comprehension.

Curricular content in undergraduate biology courses has been historically hetero and cisnormative due to various cultural stigmas, biases, and discrimination. Such curricula may be partially responsible for why LGBTQ+ students in STEM are less likely to complete their degrees than their non-LGBTQ+ counterparts. We developed Broadening Perspective Activities (BPAs) to expand the representation of marginalized perspectives in the curriculum of an online, upper-division, undergraduate animal behavior course, focusing on topics relating to sex, gender, and sexuality.

Executive function deficits in congenital heart surgical patients: prevalence and timing of presentation.

Background: Congenital heart patients undergoing congenital heart surgery in the first year of life are at high risk of having a neurodevelopmental disorder. The most common difficulties are related to executive functioning. The following questions were assessed in the current project: Are patients having congenital heart surgery after one year of life at lower risk for neurodevelopmental disorders? At what age do executive function deficits manifest?

Methods: We evaluated executive function in four groups of congenital heart patients who had undergone congenital heart surgery.

Atypical Hemolytic Uremic Syndrome Following Influenza B: A Case Report.

Background: Atypical hemolytic uremic syndrome (aHUS) is a thrombotic microangiopathy that presents with a triad of hemolytic anemia, thrombocytopenia, and acute kidney impairment. It can be attributed to mutations in an array of different complement proteins leading to the overactivation of the complement system, the most impacted being the alternative pathway. Though rare, influenza B has been documented as a potential trigger to the development of aHUS.

Variation in Plumage Coloration of Rosy-Faced Lovebirds (Agapornis roseicollis): Links to Sex, Age, Nutritional Condition, Viral Infection, and Habitat Urbanization.

Expression of vibrant plumage color plays important communication roles in many avian clades, ranging from penguins to passerines, but comparatively less is known about color signals in parrots (order Psittaciformes). We measured variation in coloration from three plumage patches (red face, blue rump, red tail) in an introduced population of rosy-faced lovebirds (Agapornis roseicollis) in Phoenix, Arizona, USA and examined color differences between the sexes and ages as well as relationships with several indices of quality, including disease presence/absence (infection with beak and feather disease, Circovirus parrot, and a polyomavirus, Gammapolyomavirus avis), nutritional state (e.g.

RNA Shielding of p65 Is Required to Potentiate Oncogenic Inflammation in TET2-Mutated Clonal Hematopoiesis.

This work identifies MALAT1 as a requisite downstream effector of oncogenic feedforward inflammatory circuits necessary for the development of TET2-mutated CH and fulminant myeloid malignancy. We elucidate a novel mechanism by which MALAT1 "shields" p65 from dephosphorylation to potentiate this circuit and nominate MALAT1 inhibition as a future therapeutic strategy.

Life history traits and cancer prevalence in birds.

Background And Objectives: Cancer is a disease that affects nearly all multicellular life, including the broad and diverse taxa of Aves. While little is known about the factors that contribute to cancer risk across Aves, life history trade-offs may explain some of this variability in cancer prevalence. We predict birds with high investment in reproduction may have a higher likelihood of developing cancer.

Urban house finches are more resistant to the effects of artificial light at night.

Rapid urbanization of habitats alters the physical, chemical, auditory, and photic environments of human and wild animal inhabitants. One of the most widespread transformations is caused by artificial light at night (ALAN), but it is not clear the extent to which individuals acclimate to such rapid environmental change. Here, we tested the hypothesis that urban birds show increased resistance to harmful behavioral, parasitological, and physiological effects of ALAN.

Genome analysis of gyroviruses identified in waterfowl in Arizona (USA).

Gyroviruses are small single-stranded DNA (ssDNA) viruses that are largely associated with birds. Chicken anemia virus is the most extensively studied gyrovirus due to its disease impact on the poultry industry. However, we know much less about gyroviruses infecting other avian species.

Correlates of Co-Infection with Coccidiosis and Avian Malaria in House Finches (Haemorhous mexicanus).

Pathogens have traditionally been studied in isolation within host systems; yet in natural settings they frequently coexist. This raises questions about the dynamics of co-infections and how host life-history traits might predict co-infection versus single infection. To address these questions, we investigated the presence of two parasites, a gut parasite (Isospora coccidians) and a blood parasite (Plasmodium spp.

Intensive Microalgal Cultivation and Tertiary Phosphorus Recovery from Wastewaters via the EcoRecover Process.

Mixed community microalgal wastewater treatment technologies have the potential to advance the limits of technology for biological nutrient recovery while producing a renewable carbon feedstock, but a deeper understanding of their performance is required for system optimization and control. In this study, we characterized the performance of a 568 m·day Clearas EcoRecover system for tertiary phosphorus removal (and recovery as biomass) at an operating water resource recovery facility (WRRF). The process consists of a (dark) mix tank, photobioreactors (PBRs), and a membrane tank with ultrafiltration membranes for the separation of hydraulic and solids residence times.

The Management of Posttraumatic Stress Disorder and Acute Stress Disorder: Synopsis of the 2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline.

Description: The U.S. Department of Veterans Affairs (VA) and Department of Defense (DoD) worked together to revise the 2017 VA/DoD Clinical Practice Guideline for the Management of Posttraumatic Stress Disorder and Acute Stress Disorder.

Using point-of-care devices to examine covariation among blood nutritional-physiological parameters and their relationships with poxvirus infection, habitat urbanization, and male plumage coloration in house finches (Haemorhous mexicanus).

The development of inexpensive and portable point-of-care devices for measuring nutritional physiological parameters from blood (e.g., glucose, ketones) has accelerated our understanding and assessment of real-time variation in human health, but these have infrequently been tested or implemented in wild animals, especially in relation to other key biological or fitness-related traits.
