Oncology nursing specialty across Latin America: struggle and achievements past and present.

Background: Latin America (LATAM) is a large region from Mexico to southern Patagonia in Chile and includes most islands in the Caribbean where Spanish is an official language. Efforts to address nursing specialization in the care of patients with cancer throughout the cancer continuum are described in narratives of oncology nursing struggles and achievements from eight Latin American countries.

Methods: Contributions by authors from Mexico, Costa Rica, Ecuador, Brazil and Chile are complemented by interview data (in Spanish by a bilingual medical anthropologist) to share the history and present status in the Dominican Republic, Peru and Argentina.

Exploration of photoprotective and antibiotic activity of wild Polypodiaceae ferns from Costa Rica.

Skin disorders affect millions of people all over the world. There are limited options to treat dermal illnesses such as vitiligo, psoriasis, and atopic dermatitis (eczema). Central American ferns are a potential source of bioactive metabolites against those diseases.

Optimization of the Extraction of Antioxidant Compounds from Roselle Hibiscus Calyxes (), as a Source of Nutraceutical Beverages.

Secondary metabolites from have been used to prevent different diseases. Roselle Hibiscus is known for being rich in phenolic bioactive compounds. The extraction conditions are directly related to the chemical composition and then to the overall bioactivity of the extract.

Bioguided Phytochemical Study of Extracts with Larvicidal Activity against .

Vector-borne diseases, such as those transmitted by , are a constant threat to inhabitants of tropical regions of the planet. Synthetic chemicals are commonly used as a strategy to control them; however, these products are known to persist in ecosystems and drive the appearance of resistance genes in arthropod vectors. Thus, the use of natural products has emerged as an environmentally friendly alternative in integrated vector control strategies.

Swainsonine, an alpha-mannosidase inhibitor, may worsen cervical cancer progression through the increase in myeloid derived suppressor cells population.

Cervical cancer, caused by high oncogenic risk Human Papillomavirus (HPV) infection, continues to be a public health problem, mainly in developing countries. Using peptide phage display as a tool to identify potential molecular targets in HPV associated tumors, we identified α-mannosidase, among other enriched sequences. This enzyme is expressed in both tumor and inflammatory compartment of the tumor microenvironment.
