Unlocking Fungal Potential: The CRISPR-Cas System as a Strategy for Secondary Metabolite Discovery.

Natural products (NPs) are crucial for the development of novel antibiotics, anticancer agents, and immunosuppressants. To highlight the ability of fungi to produce structurally diverse NPs, this article focuses on the impact of genome mining and CRISPR-Cas9 technology in uncovering and manipulating the biosynthetic gene clusters (BGCs) responsible for NP synthesis. The CRISPR-Cas9 system, originally identified as a bacterial adaptive immune mechanism, has been adapted for precise genome editing in fungi, enabling targeted modifications, such as gene deletions, insertions, and transcription modulation, without altering the genomic sequence.

Examining dental providers counseling on human papillomavirus vaccine: Insights from parents and dental professionals.

Objectives: To (1) assess perceptions of parents of patients ages 9-17 years regarding human papillomavirus (HPV) vaccine counseling and a same-day HPV vaccine program, and (2) assess perceptions among dental staff who actively participated in the same administration program.

Methods: We conducted a post-evaluation, convenience survey of parents of patients aged 9-17 and dental staff at a large-urban federally qualified healthcare center (FQHC) from July 25, 2022, to August 26, 2022. Parent and staff perceptions were assessed using validated instruments whenever possible.

Biosynthetic gene clusters with biotechnological applications in novel Antarctic isolates from Actinomycetota.

Actinomycetota have been widely described as valuable sources for the acquisition of secondary metabolites. Most microbial metabolites are produced via metabolic pathways encoded by biosynthetic gene clusters (BGCs). Although many secondary metabolites are not essential for the survival of bacteria, they play an important role in their adaptation and interactions within microbial communities.

Role of NbO Crystal Phases on the Photocatalytic Conversion of Lignin Model Molecules and Selectivity for Value-Added Products.

The photocatalytic conversion in aqueous media of phenol and guaiacol as a lignin model compound using NbO with different crystal phases was studied. NbO particles were synthesized using hydrothermal methods, where it was observed that changes in the solvent control their morphology and crystal phase. Different photocatalytic behavior of NbO was observed with the selected model compounds, indicating that its selection directly impacts the resulting conversion and selectivity rates as well as the reaction pathway, highlighting the relevance of model molecule selection.

Gamma-ray sources imaging and test-beam results with MACACO III Compton camera.

Hadron therapy is a radiotherapy modality which offers a precise energy deposition to the tumors and a dose reduction to healthy tissue as compared to conventional methods. However, methods for real-time monitoring are required to ensure that the radiation dose is deposited on the target. The IRIS group of IFIC-Valencia developed a Compton camera prototype for this purpose, intending to image the Prompt Gammas emitted by the tissue during irradiation.
