Microplastics absent from reef fish in the Marshall Islands: Multistage screening methods reduced false positives.

Island communities, like the Republic of the Marshall Islands (RMI), depend on marine resources for food and economics, so plastic ingestion by those resources is a concern. The gastrointestinal tracts of nine species of reef fish across five trophic groups (97 fish) were examined for plastics >1 mm. Over 2100 putative plastic particles from 72 fish were identified under light microscopy.

A Dosimetric Correlation Between Radiation Dose to Bone and Reduction of Hemoglobin Levels After Radiation Therapy for Prostate Cancer.

Purpose: The aim of this work was to investigate the correlation between dose to pelvic bone marrow and anemia when treating prostate cancer (PC) with definitive radiation.

Methods And Materials: Patients were selected from a prospective institutional database of patients with PC treated between 2008 and 2021. Pelvic bone (L3/L4 interface through ischial tuberosities) was contoured, and the dose to this structure was calculated.

Exploring the role of neuronal-enriched extracellular vesicle miR-93 and interoception in major depressive disorder.

Major depressive disorder (MDD) is associated with interoceptive processing dysfunctions, but the molecular mechanisms underlying this dysfunction are poorly understood. This study combined brain Neuronal-Enriched Extracellular Vesicle (NEEV) technology and serum markers of inflammation and metabolism with Functional Magnetic Resonance Imaging (fMRI) to identify the contribution of gene regulatory pathways, in particular micro-RNA (miR) 93, to interoceptive dysfunction in MDD. Individuals with MDD ( = 44) and healthy comparisons (HC; = 35) provided blood samples and completed an interoceptive attention task during fMRI.

Augmented Reality Demonstration Survey Results From a Veteran Affairs Medical Center.

Background: Augmented reality (AR) has a wide range of potential applications to enhance health care. Understanding how the introduction of a new technology may impact employees is essential for overall health care system success.

Methods: Survey responses were obtained before and after a health care-focused interactive AR demonstration at a US Department of Veterans Affairs (VA) medical center.

Evaluation of the impact of formaldehyde fumigation during the hatching phase on contamination in the hatch cabinet and early performance in broiler chickens.

Commercial hatch cabinet environments promote replication of microorganisms. These pathogenic or apathogenic microorganisms may serve as pioneer colonizers of the gastrointestinal tract (GIT) of poultry. Some of these pioneer colonizers, such as Escherichia coli and Enterococcus spp.
