Neglected class A carbapenemases: Systematic review of IMI/NmcA and FRI from a One Health perspective.

Carbapenemase-producing Enterobacterales are pathogens classified as a critical priority by the World Health Organization and a burden on human health worldwide. IMI, NmcA, and FRI are under-detected class A carbapenemases that have been reported in the human, animal and environmental compartments, particularly these last 5 years. Bacteria producing these carbapenemases have been mostly identified in digestive carriage screenings, but they are also involved in severe infections, such as bacteremia.

Immunohistochemical expression of TLR1, TLR2, TLR4, and TLR9 in the different types of lesions associated with bovine paratuberculosis.

The factors that determine the appearance of the different pathologic forms associated with bovine paratuberculosis are not fully understood, but new research suggests a critical role of innate immunity. Toll-like receptors (TLRs) trigger the recognition of invading pathogens by innate immune cells and the onset of specific immune responses. The aim of this work was to assess, immunohistochemically, the expression of TLR1, TLR2, TLR4, and TLR9 in intestinal samples of 20 cows showing different types of paratuberculous lesions: uninfected controls, focal lesions, paucibacillary, and multibacillary diffuse forms.

Disulfiram-Loaded Nanoparticles Inhibit Long-Term Proliferation on Preadipocytes.

Introduction: Disulfiram (DSF) reduces insulin resistance and weight gain in obese mice. However, the effect on adipose tissue is unexplored due to their high instability under physiological conditions, limiting clinical applications. Thus, it is meaningful to develop a DSF carrier for sustained release to adipose tissue.

Evaluation of alternative vaccination routes against paratuberculosis in goats.

Paratuberculosis is a chronic granulomatous enteritis, caused by subspecies (), that affects ruminants worldwide. Vaccination has been considered the most cost-effective method for the control of this disease in infected dairy herds. However, currently available vaccines do not provide complete protection and interfere with the diagnosis of both paratuberculosis and bovine tuberculosis, limiting its use.

Silk Fibroin Nanoparticles as a Drug Delivery System of 3,3'-Diindolylmethane with Potential Antiobesogenic Activity.

Obesity is a global disease characterized by excessive lipid accumulation in the adipose tissue. There is an urgent need to explore alternative compounds to treat obesity. Low-molecular-weight compounds from plants, like 3,3'-diindolylmethane (DIM), are emerging as potential alternatives for obesity treatment.

Wood Anatomical and Demographic Similarities Between Self-Standing Liana and Tree Seedlings in Tropical Dry Forests of Colombia.

Canopy lianas differ considerably from trees in terms of wood anatomical structure, and they are suggested to have a demographic advantage-faster growth and higher survival-than trees. However, it remains unclear whether these anatomical and demographic differences persist at the seedling stage, when most liana species are self-standing and, consequently, might be ecologically similar to trees. We assessed how self-standing liana and tree seedlings differ in relation to wood anatomy, growth, and survival.

Homology-based identification and structural analysis of Annexins and Serine proteases to search molecules for wound healing applications.

Chronic wounds and burns are a worldwide healthcare problem that erodes patients' well-being and healthcare systems. This silent and costly epidemic requires new, cost-efficient solutions to improve patients' physical and economic welfare. Eschar-degrading vegetal and bacterial proteases have been utilized as a solution.

Linking seedling wood anatomical trade-offs with drought and seedling growth and survival in tropical dry forests.

Wood anatomy plays a key role in plants' ability to persist under drought and should therefore predict demography. Plants balance their resource allocation among wood cell types responsible for different functions. However, it remains unclear how these anatomical trade-offs vary with water availability, and the extent to which they influence demographic rates.

Aeromedical Considerations for Patient Safety in Aesthetic Medical Tourism.

This study explores the complexities of AMT, emphasizing the intersection of plastic surgery and aerospace medicine, to elucidate the incidence of complications, identify associated variables, and introduce aeromedical considerations to proactively enhance patient safety.

Bioprospection of rattlesnake venom peptide fractions with anti-adipose and anti-insulin resistance activity .

Animal venoms are natural products that have served as a source of novel molecules that have inspired novel drugs for several diseases, including for metabolic diseases such as type-2 diabetes and obesity. From venoms, toxins such as exendin-4 () and crotamine () have demonstrated their potential as treatments for obesity. Moreover, other toxins such as Phospholipases A and Disintegrins have shown their potential to modulate insulin secretion in vitro.

Evaluating the suitability of placental bovine explants for ex vivo modelling of host-pathogen interactions in Neospora caninum infections.

Bovine abortions, often caused by infectious agents like Neospora caninum, inflict substantial economic losses. Studying host-pathogen interactions in pregnant cows is challenging, and existing cell cultures lack the intricate complexity of real tissues. To bridge the gap between in vitro and in vivo models, we explored the use of cryopreserved bovine placental explants.

Insights into the mechanism of crotamine and potential targets involved in obesity-related metabolic pathways.

Crotamine (Ctm) is a peptide isolated from Crotalus durissus terrificus venom. This molecule has been demonstrated to diminish body weight gain and enhance browning in adipose tissue, glucose tolerance, and insulin sensitivity; hence, it has been postulated as an anti-obesogenic peptide. However, the mechanism to elicit the anti-obesogenic effects has yet to be elucidated.

ESBL-producing Escherichia coli prevalence and sharing across seabirds of central Chile.

Antimicrobial resistance (AMR) is a major global public threat, now largely reported in natural environments. Seabirds are carriers of extended-spectrum β-lactamase-producing Escherichia coli (ESBL-E. coli), but different foraging and breeding behaviour could impact ESBL-E.

Co-expression of VP2, NS1 and NS2-Nt proteins by an MVA viral vector induces complete protection against bluetongue virus.

Introduction: Bluetongue (BT), caused by bluetongue virus (BTV), is an important arthropod-borne livestock disease listed by the World Organization for Animal Health. Live-attenuated and inactivated vaccines have permitted to control BT but they do not simultaneously protect against the myriad of BTV serotypes. Recently, we identified the highly conserved BTV nonstructural protein NS1 and the N-terminal region of NS2 as antigens capable of conferring multiserotype protection against BTV.

Participants were surveyed before and after the use of low-fidelity mannequins to simulate two surgical techniques for PAS (one-step conservative surgery [OSCS] and modified subtotal hysterectomy [MSTH]), within a multimodal educational workshop.

Effects of Optimal Temperature Control in Body Contouring Surgery: A Nonrandomized Controlled Clinical Trial.

Background: Perioperative hypothermia in plastic surgery has underestimated risks, including increased risk of infection, cardiac events, blood loss, prolonged recovery time, and increased nausea, pain, and opioid usage. Inadequate preventive measures can result in up to 4 hours of normothermia restoration.

Objectives: The aim was to compare the impact of different strategies for normothermia during plastic surgery procedures and their relationship with clinical outcomes.

Probiotic bacteria can modulate immune responses to paratuberculosis vaccination.

subsp. (Map) is the etiological agent of paratuberculosis (PTB), a chronic intestinal inflammatory disease that causes high economical losses in dairy livestock worldwide. Due to the absence of widely available preventive or therapeutical treatments, new alternative therapies are needed.

No Evidence of Neutrophil Response Modulation in Goats after Immunization against Paratuberculosis with a Heat-Inactivated Vaccine.

Neutrophils are believed to play a role in the initial stages of paratuberculosis, and it has recently been demonstrated that vaccination can modulate their function via priming or through epigenetic and metabolic reprogramming (training). Modulation of the neutrophil response against subspecies () through vaccination has been demonstrated in a rabbit model but not in ruminants. Therefore, in the present work, the effect of vaccination on the response of caprine neutrophils against was studied.

Data-Driven Surveillance Protocol for Patients at Risk for Peritoneal Recurrence of Primary Colon Cancer: Surveillance for Peritoneal Carcinomatosis.

Peritoneal carcinomatosis (PC) is rarely discovered early due to low sensitivity of screening imaging and tumor markers, however, earlier identification may improve outcomes. This study assesses risk factors and time to recurrence of PC and implementation of a surveillance system. Patients with stage II-III colon adenocarcinoma undergoing curative colectomy between 2005-2022 were retrospectively reviewed at a single tertiary care institution.

An assessment of the owned canine and feline demographics in Chile: registration, sterilization, and unsupervised roaming indicators.

The global rise in companion animal populations, particularly dogs and cats, is driven by emotional and social benefits for owners, and their population management is becoming critically important to avoid a plethora of adverse effects on themselves, humans, and wildlife. We estimated the size and density of the owned canine and feline population in Chile and evaluated the status of microchipping, registration, sterilization rates, and the proportion of owned animals that roam unsupervised. A cross-sectional household survey in 36 districts was conducted and standard inferential statistics was employed to analyze differences between cats and dogs, sexes within each species, and between rural and urban areas.
