A multi-centre randomized controlled trial investigating Consolidation Chemotherapy with and without oxaliplatin in distal rectal cancer and Watch & Wait.

Background: Neoadjuvant chemoradiation(nCRT) has been considered the preferred initial treatment strategy for distal rectal cancer. Advantages of this approach include improved local control after radical surgery but also the opportunity for organ preserving strategies (Watch and Wait-WW). Consolidation chemotherapy(cCT) regimens using fluoropyrimidine-based with or without oxalipatin following nCRT have demonstrated to increase complete response and organ preservation rates among these patients.

Impact of cranial stereotactic radiotherapy associated with immunotherapy with nivolumab and ipilimumab on overall survival in patients with melanoma brain metastases: a real-world evidence.

Purpose: To evaluate the impact of cranial stereotactic radiotherapy (SRT) on overall survival (OS) of melanoma brain metastases (MBM) patients treated with combined nivolumab and ipilimumab (CNI) in a contemporary and real-world setting.

Methods/patients: The study was performed by using TriNetX, a global health network dataset of electronic medical records from patients in 49 healthcare organizations. We queried for patients with specific terms between January 2016 and December 2020 and run a propensity score matching (PSM) analysis.

Polyculture of bullfrog tadpoles and Nile tilapia fry.

Two experiments were carried out to test better stocking proportion according to animal size for tilapia (Oreochromis niloticus) and tadpole (Lithobates catesbeianus). The experiments were laid out in a completely randomized design with five treatments (in Experiment I) and four treatments (in Experiment II). In Experiment I, the treatments consisted of a tilapia monoculture; a 75% tilapia + 25% tadpole polyculture; a 50% tilapia + 50% tadpole; a 25% tilapia + 75% tadpole; and a tadpole monoculture.

Raman, IR, UV-vis and EPR characterization of two copper dioxolene complexes derived from L-dopa and dopamine.

The anionic complexes [Cu(L(1-))3](1-), L(-)=dopasemiquinone or L-dopasemiquinone, were prepared and characterized. The complexes are stable in aqueous solution showing intense absorption bands at ca. 605 nm for Cu(II)-L-dopasemiquinone and at ca.
