Abolition and harm reduction in the struggle for "Care, Not Cages".

Care that is organized around the principles of harm reduction and the movement for police and prison abolition has the potential to uproot and transform structural causes of harm and violence, in the interconnected crises of drug-related harm, policing, and punishment. The United States' crisis of overdose and drug-related harm and its system of policing and punishment are historically and empirically linked phenomena. The abandonment of people whose use of drugs leads to their premature death, in the form of an overdose, is directly and indirectly connected to wider systems of criminalization and incarceration that also produce premature suffering and death.

Assessing the role of sow parity on PRRSv detection by RT-qPCR through weekly processing fluids monitoring in breeding herds.

The use of processing fluids to monitor the breeding herd's porcine reproductive and respiratory syndrome (PRRS) status has gained industry acceptance. However, little is known about PRRS virus RT-qPCR detection dynamics in processing fluids and factors that may contribute to maintain PRRS virus in the herd after an outbreak. This study aimed to describe weekly RT-qPCR processing fluid results in breeding herds after an outbreak and to evaluate the proportion of RT-qPCR positive results among parity groups.

Advocacy for Health Justice: An Innovative Pilot Course for MD and Master of Public Policy Students.

: U.S. medical schools are searching for ways to address issues of health justice in undergraduate medical education.

Description of changes of key performance indicators and PRRSV shedding over time in a naïve breeding herd following a PRRS MLV exposure.

Porcine reproductive and respiratory syndrome (PRRS) is an important economic swine disease. The usage of PRRS-modified live vaccines (MLV) is the predominant breeding herd immunologic solution used in the United States to minimize the economic losses associated with wild-type PRRS infection. Most of the current information on the effects of contemporary PRRS MLV vaccination on breeding herd performance under field conditions comes from herds with previous PRRS virus (PRRSV) exposure.

Repurposing existing medications for coronavirus disease 2019: protocol for a rapid and living systematic review.

Background: Coronavirus disease 2019 (COVID-19) has no confirmed specific treatments. However, there might be in vitro and early clinical data as well as evidence from severe acute respiratory syndrome and Middle Eastern respiratory syndrome that could inform clinicians and researchers. This systematic review aims to create priorities for future research of drugs repurposed for COVID-19.

Reduction of Sb(V) by coupled biotic-abiotic processes under sulfidogenic conditions.

Increasing use and mining of antimony (Sb) has resulted in greater concern involving its fate and transport in the environment. Antimony(V) and (III) are the two most environmentally relevant oxidation states, but little is known about the redox transitions between the two in natural systems. To better understand the behavior of antimony in anoxic environments, the redox transformations of Sb(V) were studied in biotic and abiotic reactors.

Nano-enabled, antimicrobial toothbrushes - How physical and chemical properties relate to antibacterial capabilities.

Over the past two decades, Ag and Zn nanoparticles have been integrated into various consumer products as a biocide. While some nano-enabled consumer products have been shown to have antibacterial properties, their antibacterial efficacy as well as the human and environmental health outcomes are not fully known. In this study, we examine a nanoparticle-enabled product that also serves as a conduit for human exposure to bacteria: toothbrushes.

Assessment of immediate production impact following attenuated PRRS type 2 virus vaccination in swine breeding herds.

Background: To mitigate production impact of porcine reproductive and respiratory syndrome (PRRS) virus outbreaks, it has been common to preventively vaccinate swine breeding herds using PRRS modified live virus (MLV) vaccine. However, attenuated PRRS virus (PRRSv) may result negative impact on farm productivity. The objective of this study was to measure the immediate impact of PRRS type 2 MLV vaccine on breeding herd performance under field conditions.

Testing the component additivity approach to surface complexation modeling using a novel cadmium-specific fluorescent probe technique.

Over the past 40 years, laboratory experiments involving single metal-single sorbent systems have been conducted in order to determine thermodynamic stability constants for metal-bacteria and metal-mineral surface complexes. The component additivity (CA) approach to surface complexation modeling (SCM) represents one method for using these experimentally-derived stability constants to predict the extent of metal adsorption in complex, multi-sorbent systems. However, quantitative tests of the CA approach are rare due to difficulties in determining the distribution of metals in complex multi-sorbent systems.

Economic Analysis of Immunization Strategies for PRRS Control [corrected].

Porcine reproductive and respiratory syndrome virus (PRRSv) is a swine-specific pathogen that causes significant increases in production costs. When a breeding herd becomes infected, in an attempt to hasten control and elimination of PRRSv, some veterinarians have adopted a strategy called load-close-expose which consists of interrupting replacement pig introductions into the herd for several weeks (herd closure) and exposing the whole herd to a replicating PRRSv to boost herd immunity. Either modified-live virus (MLV) vaccine or live field-virus inoculation (FVI) is used.

Regulation of Serum Response Factor and Adiponectin by PPARγ Agonist Docosahexaenoic Acid.

Recent studies indicate that significant health benefits involving the regulation of signaling proteins result from the consumption of omega-3 polyunsaturated fatty acids (ω-3 PUFAs). Serum response factor (SRF) is involved in transcriptional regulation of muscle growth and differentiation. SRF levels are increased in the aging heart muscle.

Histoplasma capsulatum and Caenorhabditis elegans: a simple nematode model for an innate immune response to fungal infection.

Histoplasma capsulatum is a primary fungal pathogen of mammals responsible for histoplasmosis. During pathogenesis H. capsulatum yeast proliferate in phagosomes of macrophages.

Impact of a magnetic ion exchange resin on ozone demand and bromate formation during drinking water treatment.

The objective of this research was to examine the impact of a magnetic ion exchange resin (MIEX) on ozone demand and bromate formation in two different ozonated waters at bench scale. The first raw water had a high bromide ion concentration, a high ozone demand, and was highly colored. Based on experimental findings from the first water, the second water was selected as a model water in which more controlled experiments were performed.

Characterization of an alternative oxidase activity of Histoplasma capsulatum.

Histoplasma capsulatum possesses a branched mitochondrial electron transport chain, with both cyanide-sensitive and -insensitive oxygen-consuming activities. The latter, carried out by a single subunit enzyme termed 'alternative oxidase', is the focus of this report. AOX1 cDNA clones were isolated and direct evidence that the cDNA ORF encodes functional alternative oxidase is reported.

Redundancy, phylogeny and differential expression of Histoplasma capsulatum catalases.

Histoplasma capsulatum produces an extracellular catalase termed M antigen, which is similar to catalase B of Aspergillus and Emericella species. Evidence is presented here for two additional catalase isozymes in H. capsulatum.
