Temporal and Notch identity determine layer targeting and synapse location of medulla neurons.

How specification mechanisms that generate neural diversity translate into specific neuronal targeting, connectivity, and function in the adult brain is not understood. In the medulla region of the optic lobe, neural progenitors generate different neurons in a fixed order by sequentially expressing a series of temporal transcription factors as they age. Then, Notch signaling in intermediate progenitors further diversifies neuronal progeny.

Roles of CDR2 and CDR2L in Anti-Yo Paraneoplastic Cerebellar Degeneration: A Literature Review.

Paraneoplastic cerebellar degeneration (PCD) is a rapidly progressive, immune-mediated syndrome characterized by the degeneration of Purkinje cells, often associated with the presence of antibodies targeting intracellular antigens within these cells. These autoantibodies are implicated in the induction of cytotoxicity, leading to Purkinje cell death, as demonstrated in in vitro models. However, the precise roles of antibodies and T lymphocytes in mediating neuronal injury remain a subject of ongoing research, with T cells appearing to be the main effectors of cerebellar injury.

The Little-Known Ribbon-Shaped Piriform Cortex: A Key Node in Temporal Lobe Epilepsy-Anatomical Insights and Its Potential for Surgical Treatment.

The piriform cortex (PC) plays a pivotal role in the onset and propagation of temporal lobe epilepsy (TLE), making it a potential target for therapeutic interventions. This review delves into the anatomy and epileptogenic connections of the PC, highlighting its significance in seizure initiation and resistance to pharmacological treatments. Despite its importance, the PC remains underexplored in surgical approaches for TLE.

A model of co-creation: strengthening primary health care (PHC) in Ghana through an innovative "Nyansapo" partnership.

The Africa Health Collaborative (AHC) initiative embarked on a transformative ten-year collaboration with Kwame Nkrumah University of Science and Technology (KNUST) and the University of Toronto (U of T) to co-create continuing education programs geared toward augmenting the proficiency of primary care practitioners in Ghana. While upholding core principles within the AHC framework, emphasizing respect, inclusivity, equity, reciprocity, ethics, dynamism, and stewardship, seven teams of U of T and KNUST faculty engaged in collaborative efforts to design, administer, and evaluate five in-person "short courses" in Ghana on Palliative Care, Quality Improvement for Health Professionals, Prehospital Emergency Care, Community Emergency Care, and Emergency Preparedness and Response to Epidemic-Prone Diseases to approximately 100 Ghanaian primary care professionals. This paper describes a model of co-creation, highlights lessons learned from a robust evaluation process, and proposes that this co-creation model can strengthen primary health care in Ghana and ultimately transform health systems in Africa.

Malaria, Dengue Fever, and Leptospirosis in the Urabá Antioqueño Region, Colombia: Etiological and Molecular Characterization among Patients with Acute Undifferentiated Febrile Illness.

Acute undifferentiated febrile illness (AUFI) is the main cause of medical attention in the tropics worldwide. Malaria, arboviral diseases, and leptospirosis are the most important etiologies. These are highly endemic in the Urabá antioqueño, Colombia, being the main causes of fever in several municipalities in this region.
