Neurofeedback: New Territories And Neurocognitive Mechanisms Of Endogenous Neuromodulation, James Sulzer, T Dorina Papageorgiou, Rainer Goebel, Talma Hendler

Faculty, Staff and Students Publications

Neurofeedback (NF) is endogenous neuromodulation of circumscribed brain circuitry. While its use of real-time brain activity in a closed-loop system is similar to brain-computer interfaces, instead of controlling an external device like the latter, the goal of NF is to change a targeted brain function. In this special issue on NF, we present current and future methods for extracting and manipulating neural function, how these methods may reveal new insights about brain function, applications, and rarely discussed ethical considerations of guiding and interpreting the brain activity of others. Together, the articles in this issue outline the possibilities of NF use …

Nuclear atypia is a hallmark of cancer. A recent model posits that excess surface area, visible as folds/wrinkles in the lamina of a rounded nucleus, allows the nucleus to take on diverse shapes with little mechanical resistance. Whether this model is applicable to normal and cancer nuclei in human tissues is unclear. We image nuclear lamins in patient tissues and find: (a) nuclear laminar wrinkles are present in control and cancer tissue but are obscured in hematoxylin and eosin (H&E) images, (b) nuclei rarely have a smooth lamina, and (c) wrinkled nuclei assume diverse shapes. Deep learning reveals the presence …

Precision oncology is driven by biomarkers. For glioblastoma multiforme (GBM), the most common malignant adult primary brain tumor, O6-methylguanine-DNA methyltransferase (MGMT) gene promoter methylation is an important prognostic and treatment clinical biomarker. Time consuming pre-analytical steps such as biospecimen storage, fixation, sampling, and processing are sources of data irreproducibility, and all these pre-analytical variables are confounded by intratumor heterogeneity of MGMT promoter methylation. To assess the effect of pre-analytical variables on GBM DNA methylation, tissue storage/sampling (CryoGrid), sample preparation multi-sonicator (PIXUL), and 5-methylcytosine (5mC) DNA immunoprecipitation (Matrix MeDIP-qPCR/seq) platforms were used. MGMT promoter methylation status assayed by MeDIP-qPCR was …

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies. Recent advances in proteomic technology and computational sciences now provide opportunities to investigate the intricate biology of the human body …

Cadasil: A Notch3-Associated Cerebral Small Vessel Disease, Lamei Yuan, Xiangyu Chen, Joseph Jankovic, Hao Deng

Faculty, Staff and Students Publications

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common hereditary cerebral small vessel disease (CSVD), pathologically characterized by a non-atherosclerotic and non-amyloid diffuse angiopathy primarily involving small to medium-sized penetrating arteries and leptomeningeal arteries. In 1996, mutation in the notch receptor 3 gene (NOTCH3) was identified as the cause of CADASIL. However, since that time other genetic CSVDs have been described, including the HtrA serine peptidase 1 gene-associated CSVD and the cathepsin A gene-associated CSVD, that clinically mimic the original phenotype. Though NOTCH3-associated CSVD is now a well-recognized hereditary disorder and the number of …

Background: Type 1 diabetes (T1D) management is challenging for young adults, who are expected to transfer from the pediatric to adult T1D healthcare system while also managing typical developmental demands (e.g., social, financial, work/school, residential). Many young adults have extended gaps in care before following up in adult care, increasing risk for poor health outcomes. There are few evidence-based programs to support young adults with T1D to promote a timelier transition during this period. This paper reports on the design of DiaBetter Together, a randomized controlled trial to evaluate a 12-month Peer Mentor-delivered intervention compared to usual care among young …

Faculty, Staff and Students Publications

Youth-onset type 2 diabetes is a heterogeneous disease with increasing prevalence in relation to increased rates of obesity in children. It has genetic, epigenetic, social, and environmental determinants. Youth-onset type 2 diabetes is alarming given a rapidly progressive course compared with the course of adult-onset disease, early-onset vascular complications, and long-term exposure to hyperglycemia and associated complications. It is often preceded by prediabetes, a disease phase where defects in β-cell function relative to insulin sensitivity emerge. Herein, we review the current understanding of the pathophysiology of prediabetes and type 2 diabetes in youth. We describe the mechanisms underlying insulin resistance, …

Retinal Ganglion Cell Circuits And Glial Interactions In Humans And Mice, Kang-Chieh Huang, Mohamed Tawfik, Melanie A Samuel

Faculty, Staff and Students Publications

Retinal ganglion cells (RGCs) are the brain's gateway for vision, and their degeneration underlies several blinding diseases. RGCs interact with other neuronal cell types, microglia, and astrocytes in the retina and in the brain. Much knowledge has been gained about RGCs and glia from mice and other model organisms, often with the assumption that certain aspects of their biology may be conserved in humans. However, RGCs vary considerably between species, which could affect how they interact with their neuronal and glial partners. This review details which RGC and glial features are conserved between mice, humans, and primates, and which differ. …
