Diversity of ectoparasitic bat flies (Diptera, Hippoboscoidea) in inter-Andean valleys: evaluating interactions in the largest inter-Andean basin of Colombia.

Article Synopsis
- Bat flies from the Streblidae and Nycteribiidae families have evolved specialized traits to feed on bats' blood and form specific associations with different bat species.
- The Magdalena River basin in Colombia, which supports 98 bat species, reveals a diverse and modular interaction between bats and bat flies through field studies and literature review.
- The study demonstrates medium specialization among bat flies, highlighting competitive relationships among species and suggesting that environmental conditions influence these dynamics in bat populations.
Article Synopsis
- Idiopathic pulmonary fibrosis (IPF) is a severe lung disease with no effective treatments, characterized by abnormal lung tissue growth and scarring.
- This study explored the potential of Allium sativum nanovesicles (AS-NV) in a mouse model of IPF and found that AS-NV reduced collagen levels and improved lung structure without harming healthy cells.
- The results indicate that AS-NV may reduce key genes associated with fibrosis and inflammation, suggesting a promising avenue for future IPF treatments, though further research is necessary.
Bocconia arborea S. Watson (Papaveraceae) is an abundant medicinal plant in the North of Morelos State, Mexico, which is used for the treatment of several diseases. The aim of current investigation was to isolate the compounds responsible of the relaxant effect shown by the active extracts.

Aims: Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive lung condition, the cause of which remains unknown and for which no effective therapeutic treatment is currently available. Chlorogenic acid (CGA), a natural polyphenolic compound found in different plants and foods, has emerged as a promising agent due to its anti-inflammatory, antioxidant, and antifibrotic properties. However, the molecular mechanisms underlying the therapeutic effect of CGA in IPF remain unclear.

Article Synopsis
- Ticks from the Amblyomma genus in Colombia, including the complexes A. maculatum, A. cajennense, and A. ovale, are known to transmit Rickettsia species, but their distribution is not fully understood.
- Predictive models showed that A. ovale and A. maculatum may expand their range by 2070, while A. mixtum and A. patinoi might see a decrease in their distribution; factors like temperature and rainfall significantly influence these changes.
- Ongoing surveillance is essential to study the potential spread of rickettsiosis related to different Rickettsia species across these tick populations and their environments.
