An implantable system for opioid safety.

Naloxone can effectively rescue victims from opioid overdose, but less than 5% survive due to delayed or absent first responder intervention. Current overdose reversal systems face key limitations, including low user adherence, false positive detection, and slow antidote delivery. Here, we describe a subcutaneously implanted robotic first responder to overcome these challenges.

Peroneus brevis split rupture is underreported on magnetic resonance imaging of the ankle in patients with chronic lateral ankle pain.

Introduction: Peroneus brevis split rupture poses a diagnostic challenge, often requiring magnetic resonance imaging (MRI), yet splits are missed in initial radiological reports. However, the frequency of reported peroneus brevis split rupture in clinical MRI examinations is unknown.

Aim: This study aimed to investigate underreporting frequency of peroneus brevis split rupture in patients with lateral ankle pain.

The zebrafish gut microbiome influences benzo[a]pyrene developmental neurobehavioral toxicity.

Early-life exposure to environmental toxicants like Benzo[a]pyrene (BaP) is associated with several health consequences in vertebrates (i.e., impaired or altered neurophysiological and behavioral development).

Mr. Toad's Wild Fungi: Fungal Isolate Diversity on Colorado Boreal Toads and their Capacity for Pathogen Inhibition.

The amphibian skin pathogen () has caused an ongoing biodiversity crisis, including in the locally endangered Colorado boreal toad (). Although researchers have investigated the bacteria living on amphibian skin and how they interact with , there is less information about fungal community members. This study describes (1) the diversity of culturable fungi from boreal toad skin, (2) which subset of these isolates is -inhibitory, and (3) how affects these isolates' growth and morphology.

Defining the environmental determinants of dysbiosis at scale with zebrafish.

The gut microbiome, critical to maintaining vertebrate homeostasis, is susceptible to a various exposures. In some cases, these exposures induce dysbiosis, wherein the microbiome changes into a state conducive to disease progression. To better prevent, manage, and treat health disorders, we need to define which exposures induce dysbiosis.

Together or Alone: Evaluating the Pathogen Inhibition Potential of Bacterial Cocktails against an Amphibian Pathogen.

The amphibian fungal skin disease () has caused major biodiversity losses globally. Several experimental trials have tested the use of Janthinobacterium lividum to reduce mortality due to infections, usually in single-strain amendments. It is well-characterized in terms of its anti- activity mechanisms.

A Metagenomic Investigation of Spatial and Temporal Changes in Sewage Microbiomes across a University Campus.

Wastewater microbial communities are not static and can vary significantly across time and space, but this variation and the factors driving the observed spatiotemporal variation often remain undetermined. We used a shotgun metagenomic approach to investigate changes in wastewater microbial communities across 17 locations in a sewer network, with samples collected from each location over a 3-week period. Fecal material-derived bacteria constituted a relatively small fraction of the taxa found in the collected samples, highlighting the importance of environmental sources to the sewage microbiome.

Bacterial Biofilm Thickness and Fungal Inhibitory Bacterial Richness Both Prevent Establishment of the Amphibian Fungal Pathogen Batrachochytrium dendrobatidis.

Host-associated microbial biofilms can provide protection against pathogen establishment. In many host-microbe symbioses (including, but not limited to humans, plants, insects, and amphibians), there is a correlation between host-associated microbial diversity and pathogen infection risk. Diversity may prevent infection by pathogens through sampling effects and niche complementarity, but an alternative hypothesis may be that microbial biomass is confounded with diversity and that host-associated biofilms are deterring pathogen establishment through space preemption.

Identifying fungal-host associations in an amphibian host system.

Host-associated microbes can interact with macro-organisms in a number of ways that affect host health. Few studies of host-associated microbiomes, however, focus on fungi. In addition, it is difficult to discern whether a fungal organism found in or on an ectotherm host is associating with it in a durable, symbiotic interaction versus a transient one, and to what extent the habitat and host share microbes.

Bacterial Community Sequences of Submerged Aquatic Vegetation in the Potomac River.

Here, we report results from PCR and sequencing of bacterial 16S rRNA genes from leaf and root surfaces from nine submerged aquatic vegetation (SAV) samples comprising five species. Samples were from four sites along the Potomac River.

PNPLA3 I148M Polymorphism in Patients with Nonalcoholic Fatty Liver Disease, Obesity and Prediabetes.

Background And Aims: Nonalcoholic fatty liver disease (NAFLD) is closely associated with obesity and insulin resistance, and therefore predisposes to type 2 diabetes and cardiovascular diseases. Lipid deposition in the liver seems to be critical in the pathogenesis of NAFLD. A common genetic variant, the patatin-like phospholipase domain-containing protein 3 (PNPLA3) has been associated with NAFLD.

The association between retinol-binding protein 4 and prediabetes in obese patients with nonalcoholic fatty liver disease.

Context: Retinol-binding protein 4 RBP4) is associated with visceral fat and insulin resistance (IR) in obesity, type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD), but some of these data remain controversial.

Objective: This study evaluated the relationship between serum RBP4 levels and prediabetes in obese patients with NAFLD.

Methods: A total of 79 obese NAFLD patients without ( = 41) and with prediabetes ( = 38) were included.

Monoallelic expression of the TTR gene as a contributor to the age at onset and penetrance of TTR-related amyloidosis.

TTR-related amyloidosis (ATTR) is manifested in two allelic forms: familial amyloid polyneuropathy (TTR-FAP) and cardiomyopathy (TTR-FAC), both caused by mutations in the TTR gene. The most prevalent mutation in Bulgaria is p.Glu89Gln.

Microbial Community Succession and Nutrient Cycling Responses following Perturbations of Experimental Saltwater Aquaria.

Although aquaria are common features of homes and other buildings, little is known about how environmental perturbations (i.e., tank cleaning, water changes, addition of habitat features) impact the diversity and succession of aquarium microbial communities.

The Effects of Captivity on the Mammalian Gut Microbiome.

Recent studies increasingly note the effect of captivity or the built environment on the microbiome of humans and other animals. As symbiotic microbes are essential to many aspects of biology (e.g.

Effect of Moderate Hepatic Impairment on the Pharmacokinetics and Pharmacodynamics of Roxadustat, an Oral Hypoxia-Inducible Factor Prolyl Hydroxylase Inhibitor.

Background And Objective: Roxadustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor in phase III development for the treatment of anaemia associated with chronic kidney disease. This study evaluated the effects of moderate hepatic impairment on roxadustat pharmacokinetics, pharmacodynamics and tolerability.

Methods: This was an open-label study in which eight subjects with moderate hepatic impairment (liver cirrhosis Child-Pugh score 7-9) and eight subjects with normal hepatic function (matched for body mass index, age and sex) received a single oral 100 mg roxadustat dose under fasted conditions.
