Fine-Tuned Expression of Evolutionarily Conserved Signaling Molecules in the Notochord.

The notochord is an axial structure required for the development of all chordate embryos, from sea squirts to humans. Over the course of more than half a billion years of chordate evolution, in addition to its structural function, the notochord has acquired increasingly relevant patterning roles for its surrounding tissues. This process has involved the co-option of signaling pathways and the acquisition of novel molecular mechanisms responsible for the precise timing and modalities of their deployment.

Targeted palliative endovascular embolization of a glomus jugulotympanicum tumor for refractory Jacobson's neuralgia: A case report.

Background: Glomus tumors around the jugular foramen and inner ear can have variable presentations, including lower cranial nerve palsies, tinnitus, hearing loss, or palpable neck mass. In general, these tumors are benign paragangliomas with the definitive treatment consisting of radiosurgery or surgery. Endovascular embolization can be added as a critical adjunctive therapy to reduce the tumor vascularity before surgical resection.

The Synergistic Combination of Curcumin and Polydatin Improves Temozolomide Efficacy on Glioblastoma Cells.

Glioblastoma (GBL) is one of the more malignant primary brain tumors; it is currently treated by a multimodality strategy including surgery, and radio- and chemotherapy, mainly consisting of temozolomide (TMZ)-based chemotherapy. Tumor relapse often occurs due to the establishment of TMZ resistance, with a patient median survival time of <2 years. The identification of natural molecules with strong anti-tumor activity led to the combination of these compounds with conventional chemotherapeutic agents, developing protocols for integrated anticancer therapies.

Hop leaves: From waste to a valuable source of bioactive compounds - A multidisciplinary approach to investigating potential applications.

After harvesting of cones used for beer production, the remaining hop vegetative biomass requires disposal. The hop plant contains bioactive compounds in all its parts-cones, leaves, and roots-exhibiting interesting antioxidant, antiviral, and antibacterial properties. In this work, extracts obtained from hop leaves, a plant material often neglected in the hop cultivation, have been investigated; the qualitative UHPLC-MS/MS and GC-TOF-MS characterization revealed the presence of bioactive compounds such as polyphenols, α- and β-acids and terpenes are present.
