Searching for More Effective Food Baits for Tephritid Fruit Flies (Diptera: Tephritidae): Performance of Newly Developed Vial-Lures Relative to Torula Yeast Borax.

Food-baited traps are an important part of early detection programs for invasive tephritid fruit fly species, as they are attractive to both sexes of all targeted species. Torula yeast borax (TYB) mixture is a standard food bait, but its longevity is limited (1-2 weeks). Synthetic food-based lures have been developed, including ammonium acetate, putrescine, and trimethylamine.

Intraspecific Morphometric Variation in a New Species of Thélohan 1892 (Cnidaria) from the South Atlantic Ocean: An Ecomorphological Study Using Geometric Morphometrics.

A new species of (Ceratomyxidae, Myxosporea) was found infecting the gall bladder of the Argentine croaker Berg 1895 (Sciaenidae, Perciformes) from the Argentine sea. Using an integrative taxonomic approach that combines morphological, bioecological, and molecular analyses, we provide evidence that clearly differentiates this species from known taxa and formally describe as a new species. This study is the first to apply landmark-based geometric morphometrics (GM) in myxozoan research, providing a detailed analysis of conspecific morphometric variation of ceratomyxid myxospores, examining their natural variation within and among different ceratomyxids infecting the gall bladder of .

Morphology and Immunoexpression of Selenoproteins in Term Placenta of Alpaca () from the Peruvian Andes.

South American camelids inhabit high-altitude environments characterized by hypoxia, influencing embryonic, fetal, and placental development. This study examined the term placenta morphology of alpacas (, N = 12) and the immunoexpression of antioxidant selenoproteins (SP). We hypothesize that the placenta of alpacas, adapted to high altitudes, has characteristics with other species also adapted to altitude.

Comparison of Resampling Methods and Radiomic Machine Learning Classifiers for Predicting Bone Quality Using Dual-Energy X-Ray Absorptiometry.

Development of an Operational Map for the 3D Printing of Phytosterol-Enriched Oleogels: Rheological Insights and Applications in Nutraceutical Design.

Three-dimensional (3D) printing attracts significant interest in the food industry for its ability to create complex structures and customize nutritional content. Printing materials, or inks, are specially formulated for food or nutraceuticals. These inks must exhibit proper rheological properties to flow smoothly during printing and form stable final structures.

Quality of life in idiopathic pulmonary fibrosis in Latin American countries.

Background: Idiopathic pulmonary fibrosis (IPF) is the most common Interstitial Lung Disease (ILD). It is characterized by dyspnoea and a progressive decline in lung function, which negatively affects life. This study aimed to evaluate Health-Related Quality of Life (HRQoL) in IPF patients in Latin American countries.

Distal realignment and medial patellofemoral complex reconstruction for the correction of patellofemoral instability in a patient with transtibial amputation.

Patellofemoral instability (PFI) is a multifactorial condition typically observed following initial traumatic patellar dislocation. PFI depends on various factors such as limb alignment, bony structure, and the integrity of static and dynamic stabilizers. Patients with below-knee amputation have a higher risk of experiencing PFI.

[Is early discharge following primary total knee arthroplasty a risk factor for the development of complications, readmissions and unscheduled consultations?].

Introduction: total knee arthroplasty (TKA) is a surgical procedure with a growing number of indications worldwide. The trend in recent years has been to reduce hospital stay without compromising safety and quality of care. The aim of this study was to determine whether early discharge (less than 24 hours) is associated with a higher rate of complications, readmissions and unscheduled visits in patients undergoing primary knee arthroplasty.

Sarcoptes scabiei infestation in llamas (Lama glama) of the Argentine Puna: Clinical study, and morphological and molecular mite identification.

Sarcoptic mange has been described in domestic South American camelids (SACs), exported to non-Andean countries, and in wild SAC in their natural habitat. Reports on the incidence of this infestation in llamas or alpacas raised in their original location, on the other hand, are missing. The present study aimed to detect and characterize cases of sarcoptic mange in herds of llamas (Lama glama) raised in the high plateau region (Puna) of the province of Jujuy, Argentina.

Description and phylogenetic position of an unusual genus and species of allocreadiid trematode from a characid freshwater fish in South America.

Ketamine administration during adolescence impairs synaptic integration and inhibitory synaptic transmission in the adult dentate gyrus.

Ketamine administration during adolescence affects cognitive performance; however, its long-term impact on synaptic function and neuronal integration in the hippocampus a brain region critical for cognition remains unclear. Using functional and molecular analyses, we found that chronic ketamine administration during adolescence exerts long-term effects on synaptic integration, expanding the temporal window in an input-specific manner affecting the inner molecular layer but not the medial perforant path inputs in the adult mouse dorsal hippocampal dentate gyrus. Ketamine also alters the excitatory/inhibitory balance by reducing the efficacy of inhibitory inputs likely due to a reduction in parvalbumin-positive interneurons number and function.

Galectin-8 and GEL01 as potential adjuvants to enhance the immune response induced by a DNA vaccine against bovine alphaherpesvirus Type-1.

Bovine alphaherpesvirus-1 (BoAHV-1) causes several symptoms in cattle, leading to significant costs for the livestock industry. In this study, we used a plasmid encoding a secreted form of BoAHV-1 glycoprotein D (pCIgD) as a DNA vaccine. To enhance the potency of the pCIgD vaccine, we used Montanide™ GEL01 PR (GEL01) and introduced Galectin-8 (Gal-8), a lectin considered a novel adjuvant due to its immunostimulatory effects, into the formulation.

Amphibian-Derived Peptides as Natural Inhibitors of SARS-CoV-2 Main Protease (Mpro): A Combined In Vitro and In Silico Approach.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has highlighted the urgent need for novel therapeutic agents targeting viral enzymes such as the main protease (Mpro), which plays a crucial role in viral replication. In this study, we investigate the inhibitory potential of 23 peptides isolated from the skin of amphibians belonging to the Hylidae and Leptodactylidae families against SARS-CoV-2 Mpro. Five peptides demonstrated significant inhibition using a colorimetric Mpro inhibition assay, with IC50 values ranging from 41 to 203 µM.

Gender biases and hate speech: Promoters and targets in the Argentinean political context.

Hate speech found in social media a place to flourish. In the Argentinean context, new right-wing parties have disrupted the political arena, winning the elections of 2023. Many of these new right-wing figures grew in popularity due to their use of social media, on a background of increasing political violence.

Low regulatory T-cells frequency is associated with graft rejection after small bowel transplantation: Clinical and experimental evidence.

Background: Intestinal transplantation (ITx) represents the only curative option for patients with irreversible intestinal failure. Nevertheless, its rejection rate surpasses that of other solid organ transplants due to the heightened immunological load of the gut. Regulatory T-cells (Tregs) are key players in the induction and maintenance of peripheral tolerance, suggesting their potential involvement in modulating host vs.
