Evaluating the Human Risks of Consumption of Foods of Bovine Origin with Ivermectin Residues in Ecuador.

Ivermectin is a widely used antiparasitic in livestock, but its use can result in residues in bovine products and excretions. The objective of the present study was to determine the presence of ivermectin residues in cattle meat, liver, milk, faeces, and urine and assess consumer risk from chronic exposure through contaminated bovine products using a deterministic approach. To determine the presence of ivermectin residues, 124 samples were analysed by liquid chromatography.

The global distribution and environmental drivers of the soil antibiotic resistome.

Background: Little is known about the global distribution and environmental drivers of key microbial functional traits such as antibiotic resistance genes (ARGs). Soils are one of Earth's largest reservoirs of ARGs, which are integral for soil microbial competition, and have potential implications for plant and human health. Yet, their diversity and global patterns remain poorly described.

Aims And Objective: To identify the current research involving interprofessional collaboration between registered nurses (RNs) and speech language pathologists (SLPs) in healthcare and educational settings.

Background: As the complexity of healthcare increases, the need for active interprofessional collaboration between RNs and SLPs grows. A review of the literature revealed no systematic reviews currently exist about interprofessional collaborative studies between RNs and SLPs.

The Associated Decision and Management Factors on Cattle Tick Level of Infestation in Two Tropical Areas of Ecuador.

Decision-making on tick control practices is linked to the level of knowledge about livestock farming and to the social context in which individuals practice them. Tick infestation is one of the main problems in tropical livestock production. The objective of this study was to characterize tick-control related practices in two tropical livestock areas and their potential association with the level of tick infestation.

[Spontaneous intrauterine depressed skull fracture: report of two cases].

Spontaneous intrauterine depressed skull fractures are a rare entity. They can appear secondarily to head trauma (before or during birth) or due to unknown etiology. They usually require a complete evaluation from pediatric neurosurgery specialists.

Diazotrophic activity and denitrification in two long-term chronosequences of maritime Antarctica.

The main goals of this study were to identify whether key processes involved in microbial soil nitrogen transformations, such as diazotrophic activity and denitrification, the chemical properties of limiting elements in the soil, and microbial community structure, differ in the different successional stages of two long term chronosequences in maritime Antarctica. Moreover, we expect the rates of diazotrophic activity and denitrification to be stimulated by increases in air temperature and moisture. To answer these questions, we selected three stages in the succession (early, mid and late) in each of two well established chronosequences: three raised beaches in Ardley Island; and the Barton Peninsula, which includes two cosmogenically dated sites and the forefield of the Fourcade glacier.

Predictive value of cardiometabolic biomarkers and depressive symptoms for symptom severity and quality of life in patients with psychotic disorders.

Background: Patients with psychotic disorders show higher rates of the metabolic syndrome (MS) between the cluster of severe mental illnesses. Depressive symptoms can worsen outcomes of individuals with psychotic disorders. However, research on the association between MS and depression in psychotic disorders and their relevance to outcomes is lacking.

Cannabinoid receptor agonists from Conus venoms alleviate pain-related behavior in rats.

Cannabinoid (CB) receptor agonists show robust antinociceptive effects in various pain models. However, most of the clinically potent CB1 receptor-active drugs derived from cannabis are considered concerning due to psychotomimetic side effects. Selective CB receptor ligands that do not induce CNS side effects are of clinical interest.

Relevance of angiogenesis in autoimmune testis inflammation.

Experimental autoimmune orchitis (EAO) is a useful model to study organ-specific autoimmunity and chronic testicular inflammation. This model reflects testicular pathological changes reported in immunological infertility in men. Progression of EAO in rodents is associated with a significantly increased percentage of testicular endothelial cells and interstitial testicular blood vessels, indicating an ongoing angiogenic process.

Pathomechanisms of Autoimmune Based Testicular Inflammation.

Infection and inflammation of the male reproductive tract are relevant causes of infertility. Inflammatory damage occurs in the special immunosuppressive microenvironment of the testis, a hallmark termed testicular immune privilege, which allows tolerance to neo-antigens from developing germ cells appearing at puberty, long after the establishment of systemic immune tolerance. Experimental autoimmune orchitis (EAO) is a well-established rodent model of chronic testicular inflammation and organ specific autoimmunity that offers a valuable tool to investigate the pathological and molecular mechanisms leading to the breakdown of the testicular immune privilege.

The influence of soil age on ecosystem structure and function across biomes.

The importance of soil age as an ecosystem driver across biomes remains largely unresolved. By combining a cross-biome global field survey, including data for 32 soil, plant, and microbial properties in 16 soil chronosequences, with a global meta-analysis, we show that soil age is a significant ecosystem driver, but only accounts for a relatively small proportion of the cross-biome variation in multiple ecosystem properties. Parent material, climate, vegetation and topography predict, collectively, 24 times more variation in ecosystem properties than soil age alone.

Zika among international travellers presenting to GeoSentinel sites, 2012-2019: implications for clinical practice.

Introduction: International travellers contribute to the rapid spread of Zika virus (ZIKV) and its sentinel identification globally. We describe ZIKV infections among international travellers seen at GeoSentinel sites with a focus on ZIKV acquired in the Americas and the Caribbean, describe countries of exposure and traveller characteristics, and assess ZIKV diagnostic testing by site.

Methods: Records with an international travel-related diagnosis of confirmed or probable ZIKV from January 2012 through December 2019 reported to GeoSentinel with a recorded illness onset date were included to show reported cases over time.

Multiple elements of soil biodiversity drive ecosystem functions across biomes.

The role of soil biodiversity in regulating multiple ecosystem functions is poorly understood, limiting our ability to predict how soil biodiversity loss might affect human wellbeing and ecosystem sustainability. Here, combining a global observational study with an experimental microcosm study, we provide evidence that soil biodiversity (bacteria, fungi, protists and invertebrates) is significantly and positively associated with multiple ecosystem functions. These functions include nutrient cycling, decomposition, plant production, and reduced potential for pathogenicity and belowground biological warfare.

Climatic vulnerabilities and ecological preferences of soil invertebrates across biomes.

Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross-biome survey including 83 locations across six continents to advance our understanding of the ecological preferences and vulnerabilities of the diversity of dominant and functionally important soil invertebrate taxa, including nematodes, arachnids and rotifers. The diversity of invertebrates was analyzed through amplicon sequencing.

Role of indoleamine 2,3-dioxygenase in testicular immune-privilege.

Male meiotic germ cell including the spermatozoa represent a great challenge to the immune system, as they appear long after the establishment of normal immune tolerance mechanisms. The capacity of the testes to tolerate autoantigenic germ cells as well as survival of allogeneic organ engrafted in the testicular interstitium have led to consider the testis an immunologically privileged site. Disruption of this immune privilege following trauma, tumor, or autoimmune orchitis often results in male infertility.

Changes in belowground biodiversity during ecosystem development.

Belowground organisms play critical roles in maintaining multiple ecosystem processes, including plant productivity, decomposition, and nutrient cycling. Despite their importance, however, we have a limited understanding of how and why belowground biodiversity (bacteria, fungi, protists, and invertebrates) may change as soils develop over centuries to millennia (pedogenesis). Moreover, it is unclear whether belowground biodiversity changes during pedogenesis are similar to the patterns observed for aboveground plant diversity.

Coupling of microbial nitrogen transformations and climate in sclerophyll forest soils from the Mediterranean Region of central Chile.

The Mediterranean region of central Chile is experiencing extensive "mega-droughts" with detrimental effects for the environment and economy of the region. In the northern hemisphere, nitrogen (N) limitation of Mediterranean ecosystems has been explained by the decoupling between N inputs and plant uptake during the dormant season. In central Chile, soils have often been considered N-rich in comparison to other Mediterranean ecosystems of the world, yet the impacts of expected intensification of seasonal drought remain unknown.

Assisted Salvage of Ischemic Fasciocutaneous Flap Using Adipose-Derived Mesenchymal Stem Cells: In-Situ Revascularization.

Unlabelled: Adipose-derived mesenchymal stem cells (ASCs) have been shown to produce vascular endothelial growth factor (VEGF) and can increase perfusion in patients with critical limb ischemia. We will show that this concept can be applied to augment blood flow in zones of flap ischemia. We presented a case study of a 26-year-old man with a complex hand injury covered by a reverse radial perforator fasciocutaneous flap, which developed ischemic necrosis and was treated by debridement, transplantation of ASCs to enhance vascular support, and saline dressings.
