Effectiveness of a protocol with antimicrobial photodynamic therapy for treating osteoradionecrosis: a retrospective study.

Objective: To compare the treatment of osteoradionecrosis (ORN) using a protocol that incorporates antimicrobial photodynamic therapy with a conventional treatment protocol.

Methodology: This retrospective study analyzed 55 patients diagnosed with ORN at a reference hospital between 2002 and 2021. Patients were treated using two different clinical protocols.

Radial glia progenitor polarity in health and disease.

Radial glia (RG) are the main progenitor cell type in the developing cortex. These cells are highly polarized, with a long basal process spanning the entire thickness of the cortex and acting as a support for neuronal migration. The RG cell terminates by an endfoot that contacts the pial (basal) surface.

Alkali Activation of Metakaolin and Wollastonite: Reducing Sodium Hydroxide Use and Enhancing Gel Formation through Carbonation.

Alkali activated materials (AAMs) offer significant advantages over traditional materials like Portland cement, but require the use of strong alkaline solutions, which can have negative environmental impacts. This study investigates the synthesis of AAMs using metakaolin and wollastonite, aiming to reduce environmental impact by eliminating sodium silicate and using only sodium hydroxide as an activator. The hypothesis is that wollastonite can provide the necessary silicon for the reaction, with calcium from wollastonite potentially balancing the negative charges usually countered by sodium in the alkaline solution.

Forebrain Eml1 depletion reveals early centrosomal dysfunction causing subcortical heterotopia.

Subcortical heterotopia is a cortical malformation associated with epilepsy, intellectual disability, and an excessive number of cortical neurons in the white matter. Echinoderm microtubule-associated protein like 1 (EML1) mutations lead to subcortical heterotopia, associated with abnormal radial glia positioning in the cortical wall, prior to malformation onset. This perturbed distribution of proliferative cells is likely to be a critical event for heterotopia formation; however, the underlying mechanisms remain unexplained.
