Isolation and Biosynthesis of Hyellamide, a Glycosylated N-Acyltyrosine Derivative, from the Cyanobacterium LEGE 07179.

Recent analyses of genome data indicate that members of the cyanobacterial order Pleurocapsales show tremendous potential for natural product discovery. However, only a few compounds have been reported from this order. Here, we report the isolation of hyellamide (), a glycosylated N-acyl tyrosine-derived eneamide, from the pleurocapsalean cyanobacterium LEGE 07179.

Measuring Minerals in Pseudocereals Using Inductively Coupled Plasma Optical Emission Spectrometry: What Is the Optimal Digestion Method?

Pseudocereals have gained attention due to their adaptability to different climates, high nutritional value, and suitability for gluten-free and plant-based diets. However, a challenge lies in the necessary adaptations in the diet pathways, mainly due to the lack of matrix-matching metrological tools. To address this problem, we developed a classification system to support laboratory decisions without shaped Proficiency Testing (PT) or Certified/Standard References Material.

Staphylococcus spp. and methicillin-resistance gene mecA dispersion in seawater: A case study of Guanabara Bay's recreational and touristic waters.

Environmental Staphylococci, particularly coagulase-negative Staphylococci (CoNS), are known reservoirs of antimicrobial resistance genes and human-animal opportunistic pathogens, yet their role within the One Health framework remains underexplored. In this study, we isolated 12 species of CoNS from two sites 10 km apart in Guanabara Bay, Rio de Janeiro, with the most frequent species being the opportunistic Staphylococcus saprophyticus (30.3 %), Staphylococcus warneri (25.

"It's a low-key thing of eugenics": Disability reproductive injustice in barriers to cervical cancer screening during the COVID-19 pandemic.

Cervical cancer screening (CCS) is a critical component of preventative sexual and reproductive healthcare, yet there are disparities in access to CCS for people with disabilities. This qualitative community-engaged study uses the disability reproductive justice framework to examine how the COVID-19 pandemic impacted people with disabilities' experiences with CCS in Canada. From May 2022 to March 2023, semi-structured interviews were conducted with 40 women and gender-diverse people with physical, sensory, cognitive, and/or mental health disabilities.

Combatting pesticide pollution: using liquid scintillation spectrometry to assess C-labeled hexachlorobenzene removal by mangrove Bacillus spp.

This study explored the ability of two Bacillus species isolated from mangrove sediments to degrade hexachlorobenzene (HCB), a persistent organic pollutant that affects the quality of surface water, groundwater, and soil. Hence, we analyzed bacterial growth in a medium with hexachlorobenzene as the sole carbon source. Moreover, chemical oxygen demand removal, ecotoxicity, and measured radiolabeled HCB degradation were assessed.
