Generation of human striatal organoids and cortico-striatal assembloids from human pluripotent stem cells.

Cortico-striatal projections are critical components of forebrain circuitry that regulate motivated behaviors. To enable the study of the human cortico-striatal pathway and how its dysfunction leads to neuropsychiatric disease, we developed a method to convert human pluripotent stem cells into region-specific brain organoids that resemble the developing human striatum and include electrically active medium spiny neurons. We then assembled these organoids with cerebral cortical organoids in three-dimensional cultures to form cortico-striatal assembloids.

A Quantitative Investigation of Pulse and Tongue Features in Post-Stroke Depressive Patients and Healthy Volunteers: An Observational Pilot Study.

Background: Depression is among the most common neuropsychiatric complications after stroke, having a negative impact on one's quality of life. A number of therapeutic modalities have been used for post-stroke depression (PSD) including traditional Chinese medicine (TCM). However, a lack of objectivity in TCM hampers further improvement in diagnosis and research, since TCM diagnosis is mainly based on subjective judgment of clinicians.

Evaluation of microbial flora in eyes with a Boston type 1 Keratoprosthesis.

Purpose: To evaluate the microbial flora of eyes with a Boston Keratoprosthesis (K-Pro).

Methods: A prospective study was performed for 17 eyes of 15 patients who underwent a K-Pro implantation between September 2005 and June 2011. Preoperative diagnoses included failed corneal grafts, limbal stem cell deficiency, chemical burns, and Stevens-Johnson Syndrome.
