Dysgraphia Following the Resection of a Left Parietal Glioma.

We report herein the case of a 41-year-old man operated on for a small inferior parietal lobule ganglioglioma with a sleep-awake-sleep protocol and language mapping to avoid major speech disorders. Postoperatively, however, writing disturbance was characterized by persistent graphemic errors that lasted for about 8 months. The topic is discussed in light of recent literature, exploring the possible relationship between writing difficulties and disconnections produced by a combination of resecting supramarginal gyrus components and interrupting arcuate fasciculus fibers.

A road map to manual segmentation of cerebral structures.

Manual segmentation is an essential tool in the researcher's technical arsenal. It is a frequent practice necessary for image analysis in many protocols, especially in neuroimaging and comparative brain anatomy. In the framework of emergence of studies focusing on alternative animal models, manual segmentation procedures play a critical role.

Evaluating the Impact of Heat Stress on Placental Function: A Systematic Review.

Ambient heat stress poses a significant threat to public health, with rising temperatures exacerbating the risks associated with pregnancy. This systematic review examined the associations between heat stress exposure and placental function, synthesizing methodologies from the existing literature to inform future research approaches. Analyzing 24 articles, it explores various study designs, temperature exposure parameters, pregnancy windows, and placental outcome variables.

Comparative analysis of lipid-peptide nanoparticles prepared via microfluidics, reverse phase evaporation, and ouzo techniques for efficient plasmid DNA delivery.

In the current "era of lipid carriers," numerous strategies have been developed to manufacture lipid nanoparticles (LNPs). Nevertheless, the potential impact of various preparation methods on the characteristics, use, and/or stability of these LNPs remains unclear. In this work, we attempted to compare the effects of three different preparation methods: microfluidics (MF), reverse phase evaporation (RV), and ouzo (OZ) on lipid-peptide NPs (LPNPs) as plasmid DNA delivery carriers.

Paraffin embedding of the whole human cerebral hemisphere to assess arterial distribution territories.

Commonly used to decode the human brain's structural complexity, dissection focuses on a given structure or region but cannot depict the whole brain organization (for example, its arterial distribution territories). Where dissection reaches its limit, the combination of tissue sectioning and 3D reconstruction may provide a volume for the assessment of structures from any view angle, following them dynamically to understand their spatial relationships. However, to produce sections, standard histological tissue processing protocols for paraffin embedding cannot be applied to a cerebral hemisphere as the latter is extensively larger than the conventional specimens.
