Harnessing Radionuclides: Unveiling the Promising Role of Radiopharmaceuticals in Cancer Theranostics and Palliative Care.

Background: In the context of modern oncology, radiogenic elements have emerged as pivotal tools for targeted cancer therapies. Elements like Iodine-131 and Yttrium-90 offer unique radiological properties that allow precise treatment delivery. This article explores their growing importance and potential in reshaping the landscape of cancer therapy.

Implementing national antimicrobial consumption in Latin America and the Caribbean: opportunities and lessons learned.

Surveillance of antimicrobial consumption (AMC) is essential to anticipate and inform policies and public health decisions to prevent and/or contain antimicrobial resistance (AMR). This manuscript shares the experience on AMC data collection in Latin American & Caribbean (LAC). The WHO GLASS-AMC methodology for AMC surveillance was used for data registration during the period 2019-2022.

Ileal Predominance in Crohn's Disease Is Associated With Increased Intestinal Surgery and Biological Therapy Use, With Lower Treatment Persistence.

Introduction: Crohn's disease (CD) varies by location, potentially affecting therapy efficacy and surgery risk, although research on this topic is conflicting. This study aims to investigate the independent association between CD location and therapeutic patterns.

Methods: We analyzed patients with CD diagnosed from January 2005 to May 2023 registered in the nationwide ENEIDA registry.

Reduced sensitivity to cocaine effects and changes in mesocorticolimbic dopamine receptors in adolescent sexually active female rats.

Rationale: The sexual behavior of the female rat is highly motivated, and the mesocorticolimbic dopaminergic system -involved in psychostimulants effects- has been implicated in its regulation. Female rats begin to express sexual behavior during adolescence, a period during which this system is not yet mature.

Objective: To examine the impact of cocaine on sexual motivation and behavior of adolescent and adult female rats, and to determine the dopamine receptors binding in mesocorticolimbic areas of these females.

Chilean brush-tailed mouse (): a diurnal precocial rodent as a new model to study visual receptive field properties of superior colliculus neurons.

Lab rodent species commonly used to study the visual system and its development (hamsters, rats, and mice) are crepuscular/nocturnal, altricial, and possess simpler visual systems than carnivores and primates. To widen the spectra of studied species, here we introduce an alternative model, the Chilean degu (). This diurnal, precocial Caviomorph rodent has a cone-enriched, well-structured retina, and well-developed central visual projections.
