Feasible cultivation of Verrucodesmus verrucosus on sterile raw wastewater for energy purposes: a case study in Mexico.

In this study, wastewater from a sewage treatment plant was used to culture the microalga, Verrucodesmus verrucosus. The ability of microalgae to adapt to adverse environments and produce high lipid concentrations was evaluated using different media, including sterile and non-sterile media and a control medium. The analysis showed that the control medium (distilled water sample enriched with fertilizer) removed 80.

Biohydrogen with negative CO emissions from municipal solid waste for decarbonising the public bus fleet. Application to the municipality of Madrid.

This study assesses the production potential, environmental impact, and economic viability of generating biohydrogen from biomethane obtained from the organic fraction of municipal solid waste (MSW) using steam methane reforming with carbon capture and storage (CCS). As the emissions are biogenic, CCS results in negative emissions. The methodology is based on a previously developed model, including techno-economic analysis based on the levelised cost of hydrogen (LCOH) and mobility (LCOM), and environmental assessment, focusing on production potential, cost estimates, and emissions impact.

Generation of a fluorescent hESC reporter line (Kle033-A-1) for the isolation of distinct midbrain progenitor cell types.

Midbrain dopaminergic (mDA) neurons derived from human pluripotent stem cells (hPSCs) offer a promising cell source for cell replacement therapy in Parkinson's disease (PD). Single-cell RNA sequencing (scRNA-seq) of the developing human ventral midbrain has identified four cell types expressing markers used to define correctly patterned mDA progenitors. Here, we use CRISPR/Cas9 to generate a fluorescent human embryonic stem cell line for the isolation of two potential mDA progenitors, Rgl1 and ProgM.

Implementation of cancer prevention practices in primary care: results of a cohort study in Chile 2018-2022.

Objectives: The burden of cancer is increasing rapidly in Latin America. Primary care has an essential role in cancer prevention, but implementation levels of prevention practices are not well known. This study evaluated implementation levels and associated factors of cancer preventive practices in primary care over time.
