Proton therapy versus conventional radiotherapy for the treatment of cavernous sinus benign meningioma, a randomized controlled phase III study protocol (COG-PROTON-01).

Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.

Bergofungin D, a peptaibol template for the introduction of chemical modifications, synthesis of analogs and comparative studies of their structures.

Bergofungin D is a helical peptide of the peptaibol family consisting of 14 amino acids, six of which are the helix inducer aminoisobutyric acid (Aib). In the second third of the sequence, a hydroxyproline causes a bending of the helix and a disruption of the hydrogen bond network, and Aib7 is the only amino acid in this region involved in the hydrogen bond network. Therefore, modification of this residue can serve as a probe to monitor the effect of introducing amino acid substitutions on this more fragile helical turn.

Assessment of endocrine disruptor impacts on lipid metabolism in a fatty acid-supplemented HepaRG human hepatic cell line.

The incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing worldwide. This disease encompasses several stages, from steatosis to steatohepatitis and, eventually, to fibrosis and cirrhosis. Exposure to environmental contaminants is one of the risk factors and an increasing amount of evidence points to a role for endocrine disrupting compounds (EDCs).

Cyanosphere Dynamic During Dolichospermum Bloom: Potential Roles in Cyanobacterial Proliferation.

Under the effect of global change, management of cyanobacterial proliferation becomes increasingly pressing. Given the importance of interactions within microbial communities in aquatic ecosystems, a handful of studies explored the potential relations between cyanobacteria and their associated bacterial community (i.e.
