Effect of silver nanoparticles on donkey sperm parameters and ultrastructure.

The aim of this study was to determine the effect of silver nanoparticles (AgNPs) on donkey sperm parameters and ultrastructure. AgNPs were synthesized, purified and resuspended in the extender. Nine frozen-thawed donkey sperm samples were exposed to different concentrations of AgNPs (0, 1.

Addressing Teenage Pregnancy and Reproductive Health Among Latinx Adolescents and Young Adults.

Despite a national decline in teenage pregnancy rates, Latinx and Black individuals continue to have higher teenage birth rates compared with White teens. In the United States, Latinx females (ages 15-19) are more than twice as likely to have a teenage birth compared with non-Latinx White teens. With an increasingly diverse nation, a shift toward culturally inclusive approaches to care is critical to achieving equitable patient outcomes.

RELATIONAL DIMENSION VERSUS ARTIFICIAL INTELLIGENCE.

Thirty years ago, we proposed the similarity between the functioning of artificial intelligence and the human psyche, suggesting multiple parallels between the Freudian model proposed in the "Project for Psychology for Neurologists" and the connectionist theories applied in the generation of parallel distributed processing systems (PDP), also known as connectionist models. These models have been and continue to be the foundation of general artificial intelligences like ChatGPT, evolving and gaining prominence in everyday life. From the earliest applications in psychiatry, recreating computationally simulated modes of illnesses, to the use of deep learning models, especially in the field of computer vision for tasks such as image recognition, segmentation, and classification.

Strategies to Reduce the Use of Antibiotics in Fresh and Chilled Equine Semen.

The study assessed the impact of four equine semen processing techniques on sperm quality and microbial load immediately post-processing and after 48 h of refrigeration. The aim was to explore the potential reduction of prophylactic antibiotic usage in semen extenders. Semen from ten adult stallions was collected and processed under a strict hygiene protocol and divided into four aliquots: Simple Centrifugation with antibiotics (SC+), Simple Centrifugation (SC-), Single-Layer Colloidal Centrifugation (CC-), and Filtration (with SpermFilter) (F-), all in extenders without antibiotics.

A Synopsis of Hepatitis C Virus Treatments and Future Perspectives.

Hepatitis C virus (HCV) infection is a worldwide public health problem. Chronic infection with HCV can lead to liver cirrhosis or cancer. Although some immune-competent individuals can clear the virus, others develop chronic HCV disease due to viral mutations or an impaired immune response.
