Periventricular nodular heterotopia (PNH) is the most common form of malformation of cortical development (MCD) in adulthood but its genetic basis remains unknown in most sporadic cases. We have recently developed a strategy to identify novel candidate genes for MCDs and to directly confirm their causative role in vivo.

The protocol describes a new method to disaggregate human tissues and to create autologous micro-grafts that, combined with collagen sponges, give rise to human bio-complexes ready to use in the treatment of skin lesions. Further, this system preserves cell viability of micro-grafts at different times after mechanical disaggregation.

Here we present a protocol for the characterization of mouse antral oocytes based on nucleolar organization.

The Mediterranean fruit fly (medfly) Ceratitis capitata (Diptera: Tephritidae) is a worldwide pest of agriculture. A deeper understanding of its biology is key to control medfly populations and thus reduce economic impact. Embryo microinjection is a fundamental tool allowing both germ-line transformation and reverse genetics studies in this species.

The development of new ultrasound (US) probes based on Capacitive Micromachined Ultrasonic Transducer (CMUT) technology requires an early realistic assessment of imaging capabilities. We describe a repeatable experimental protocol for US image acquisition and comparison with magnetic resonance images, using an ex vivo bovine brain as an imaging target.

Here, we present a protocol for non-invasive assessment of oocyte developmental competence performed during their in vitro maturation from the germinal vesicle to the metaphase II stage. This method combines time-lapse imaging with particle image velocimetry (PIV) and neural network analyses.

Heterogeneous distribution of HER2-positive cells can be observed in a subset of breast cancers and generates clinical dilemmas. Here, we introduce a reliable and cost-effective protocol to define, quantify, and compare HER2 intra-tumor genetic heterogeneity in a large series of heterogeneously processed breast cancers.

The manuscript describes a chip-based digital PCR assay to detect a rare CDH1 transcript variant (CDH1a) in fresh-frozen normal and tumor tissues obtained from patients with gastric cancer.

We detail how to conduct a meta-analysis of voxel-based neuroimaging studies using Seed-based d Mapping with Permutation of Subject Images (SDM-PSI).

This protocol describes a method to track individual brain-aging trajectories through a brain donation program and proper characterization of brains. Brain donors are involved in a long-term longitudinal study including serial multi-dimensional assessments. The protocol contains a detailed description of brain processing and an accurate diagnostic methodology.

We demonstrate how to deploy a real-time psychosis risk calculation and alerting system based on CogStack, an information retrieval and extraction platform for electronic health records.

The protocol described in this manuscript explains the steps for the fabrication of a soluble extracellular matrix (ECM) from the human pancreas. The solubilized ECM powder obtained through this protocol may be used for the recapitulation of pancreatic islets’ microenvironment in vitro and, potentially, in vivo settings.

Here, we present a protocol for screening soil biodiversity to look for fungal strains involved in the degradation of recalcitrant materials. First, fungal strains able to grow on humic acids or lignocellulose are isolated. Their activity is then tested both in enzymatic assays and on pollutants such as hydrocarbons and plastics.
