Mitochondrial Genomic Variation in Rare and Metabolic Diseases: From Heteroplasmy to Precision Medicine

Mitochondrial DNA (mtDNA) variation has traditionally been investigated in the context of human evolution and rare mitochondrial diseases; however, growing evidence suggests that it may also contribute to susceptibility to common metabolic disorders. This review integrates curren...

Isolation and Characterization of Lytic Bacteriophages Targeting Clinical Staphylococcus Other Than S. aureus

Abstract Staphylococcus spp., other than S. aureus (SOSA, formerly CoNS), are opportunistic pathogens often linked to biofilm infections on indwelling devices. Their rising antibiotic resistance highlights the need for novel therapies. Bacteriophages are promising due to their sp...

Soil environmental background values of potentially toxic elements in Topsoil’s from Karst environments; the case of Peninsula of Yucatan Mexico

Abstract Accurate assessment of soil contamination by potentially toxic elements requires knowledge of local background values; only in this way can false positives or negatives be avoided. The objective of this study was to define environmental background concentrations of poten...

Do sea lions fall silent when fish have something to say?

Abstract Coastal soundscapes are complex systems composed of many biological sounds, among which fish often play a central role. Marine mammal vocalizations can also contribute substantially, either when animals pass through an area or because their loud calls can be heard from o...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Ultrasound-Assisted Enzymatic Processing of Grasshopper (Sphenarium purpurascens): Comparative Assessment and Characterization of Protein Hydrolysates

The increasing demand for sustainable protein sources has stimulated interest in edible insects such as the Mexican grasshopper (Sphenarium purpurascens). This study evaluated grasshopper flour as a substrate for producing protein hydrolysates by ultrasound-assisted enzymatic hyd...
