Decades of research have established that the home language environment, especially quality of caregiver speech, supports language acquisition during infancy. However, the neural mechanisms behind this phenomenon remain under studied. In the current study, we examined associations between the home language environment and structural coherence of white matter tracts in 52 typically developing infants from English speaking homes in a western society. Infants participated in at least one MRI brain scan when they were 3, 6, 12, and/or 24 months old. Home language recordings were collected when infants were 9 and/or 15 months old. General linear regression models indicated that …

Evaluating Motion Of Pancreatic Tumors And Anatomical Surrogates Using Cine Mri In 0.35t Mrgrt Under Free Breathing Conditions, Benjamin Lewis, Anamaria Guta, Jaeik Shin, Zhen Ji, Jin Sung Kim, Taeho Kim

2020-Current year OA Pubs

Treatment tolerability is a significant limitation to pancreatic cancer treatment with radiotherapy due to proximity to highly radiosensitive organs and respiratory motion necessitating expanded target margins. Further, pancreatic tumors are difficult to visualize on conventional radiotherapy systems. Surrogates are often used to locate the tumor but are often inconsistent and do not provide strong positional relations throughout the respiratory cycle. This work utilizes a retrospective dataset of 45 pancreatic cancer patients treated on an MR-Linac system with cine MRI acquired for real-time target tracking. We investigated intra-fraction motion of tumors and two abdominal surrogates, leading to prediction models between the …

"Brain Age" Predicts Disability Accumulation In Multiple Sclerosis, Matthew R Brier, Zhuocheng Li, Maria Ly, Helmet T Karim, Leda Liang, Weixin Du, John E Mccarthy, Anne H Cross, Tammie L S Benzinger, Robert T Naismith, Salim Chahin

OBJECTIVE: Neurodegenerative conditions often manifest radiologically with the appearance of premature aging. Multiple sclerosis (MS) biomarkers related to lesion burden are well developed, but measures of neurodegeneration are less well-developed. The appearance of premature aging quantified by machine learning applied to structural MRI assesses neurodegenerative pathology. We assess the explanatory and predictive power of "brain age" analysis on disability in MS using a large, real-world dataset.

METHODS: Brain age analysis is predicated on the over-estimation of predicted brain age in patients with more advanced pathology. We compared the performance of three brain age algorithms in a large, longitudinal dataset ( …

OBJECTIVE: Accumulation of misfolded superoxide dismutase-1 (SOD1) is a pathological hallmark of SOD1-related amyotrophic lateral sclerosis (ALS) and is observed in sporadic ALS where its role in pathogenesis is controversial. Understanding in vivo protein kinetics may clarify how SOD1 influences neurodegeneration and inform optimal dosing for therapies that lower SOD1 transcripts.

METHODS: We employed stable isotope labeling paired with mass spectrometry to evaluate in vivo protein kinetics and concentration of soluble SOD1 in cerebrospinal fluid (CSF) of SOD1 mutation carriers, sporadic ALS participants and controls. A deaminated SOD1 peptide, SDGPVKV, that correlates with protein stability was also measured.

RESULTS: In …

The Mitophagy Receptor Bnip3 Is Critical For The Regulation Of Metabolic Homeostasis And Mitochondrial Function In The Nucleus Pulposus Cells Of The Intervertebral Disc, Vedavathi Madhu, Miriam Hernandez-Meadows, Paige K Boneski, Yunping Qiu, Anyonya R Guntur, Irwin J Kurland, Ruteja A Barve, Makarand V Risbud

The contribution of mitochondria to the metabolic function of hypoxic NP cells has been overlooked. We have shown that NP cells contain networked mitochondria and that mitochondrial translocation of BNIP3 mediates hypoxia-induced mitophagy. However, whether BNIP3 also plays a role in governing mitochondrial function and metabolism in hypoxic NP cells is not known. BNIP3 knockdown altered mitochondrial morphology, and number, and increased mitophagy. Interestingly, BNIP3 deficiency in NP cells reduced glycolytic capacity reflected by lower production of lactate/H

Diabetes-Related Quality Of Life Assessment In Children Following Total Pancreatectomy With Islet Autotransplantation., Jacob M. Redel, Lindsey Hornung, Deborah Elder, Jaimie D. Nathan, Sarah Corathers, Kristin L. Rich, Maisam Abu-El-Haija

Manuscripts, Articles, Book Chapters and Other Papers

Total pancreatectomy with islet autotransplantation (TPIAT) can improve pain and reduce functional impairment associated with acute recurrent or chronic pancreatitis. However, long-term glucose monitoring and insulin therapy are often required, which can adversely affect the quality of life. We sought to evaluate diabetes-related quality of life (DR-QOL) in youth who underwent TPIAT and compare it to the youth with new-onset type 1 diabetes (T1D). The Pediatric Quality of Life Inventory™ 3.2 Diabetes Module (PedsQL™ DM) was used to assess DR-QOL in 46 youth (< 20 years old) who underwent TPIAT. The PedsQL™ DM scores were analyzed for statistically significant changes and minimally important clinical differences (MCID) over time post-TPIAT. Scores at 12 months (n = 52) and 24 months (n = 58) after diagnosis of T1D. The diabetes …

BACKGROUND: Literature on colorectal cancer outcomes in individuals of Middle Eastern and North African (MENA) descent is limited. To address this gap, we estimated five-year colorectal cancer-specific survival by race and ethnicity, including MENA individuals, in a diverse, population-based sample in California.

METHODS: We identified adults (ages 18-79 years) diagnosed with a first or only colorectal cancer in 2004 to 2017 using the California Cancer Registry (CCR), including non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, Hispanic, and MENA individuals. For each racial/ethnic group, we calculated five-year colorectal cancer-specific survival and used Cox proportional hazards regression models to examine the association of …

Aligning Germline Cancer Predisposition With Tumor-Based Next-Generation Sequencing For Modern Oncology Diagnosis, Interception, And Therapeutic Development, Timothy A Yap, Zsofia K Stadler, Leigh Anne Stout, Bryan P Schneider

Faculty, Staff and Student Publications

In the era of precision medicine, genomic interrogation for identification of both germline and somatic genetic alterations has become increasingly important. While such germline testing was usually undertaken via a phenotype-driven single-gene approach, with the advent of next-generation sequencing (NGS) technologies, the widespread utilization of multigene panels, often agnostic of cancer phenotype, has become a commonplace in many different cancer types. At the same time, somatic tumor testing in oncology performed for the purpose of guiding therapeutic decisions for targeted therapies has also rapidly expanded, recently starting to incorporate not just patients with recurrent or metastatic cancer but even patients …

Distinct tissue-specific mechanisms mediate insulin action in fasting and postprandial states. Previous genetic studies have largely focused on insulin resistance in the fasting state, where hepatic insulin action dominates. Here we studied genetic variants influencing insulin levels measured 2 h after a glucose challenge in >55,000 participants from three ancestry groups. We identified ten new loci (P < 5 × 10-8) not previously associated with postchallenge insulin resistance, eight of which were shown to share their genetic architecture with type 2 diabetes in colocalization analyses. We investigated candidate genes at a subset of associated loci in cultured cells and identified nine candidate genes newly implicated in the expression or trafficking of GLUT4, the key glucose transporter in postprandial glucose uptake in muscle and fat. By focusing on postprandial insulin resistance, we highlighted the mechanisms of action at type 2 diabetes loci that are not adequately captured by studies of fasting glycemic traits.
