2020-Current year OA Pubs

The envelope glycoprotein GP of the ebolaviruses is essential for host cell entry and the primary target of the host antibody response. GP is heavily glycosylated with up to 17 N-linked sites, numerous O-linked glycans in its disordered mucin-like domain (MLD), and three predicted C-linked mannosylation sites. Glycosylation is important for host cell attachment, GP stability and fusion activity, and shielding from neutralization by serum antibodies. Here, we use glycoproteomics to profile the site-specific glycosylation patterns of ebolavirus GP. We detect up to 16 unique O-linked glycosylation sites in the MLD, and two O-linked sites in the receptor-binding GP1 subunit. …

Engineering Hyaluronic Acid For The Development Of New Treatment Strategies For Osteoarthritis, Yu Seon Kim, Farshid Guilak

2020-Current year OA Pubs

Osteoarthritis (OA) is a degenerative joint disease that is characterized by inflammation of the joints, degradation of cartilage, and the remodeling of other joint tissues. Due to the absence of disease-modifying drugs for OA, current clinical treatment options are often only effective at slowing down disease progression and focus mainly on pain management. The field of tissue engineering has therefore been focusing on developing strategies that could be used not only to alleviate symptoms of OA but also to regenerate the damaged tissue. Hyaluronic acid (HA), an integral component of both the synovial fluid and articular cartilage, has gained widespread …

The Cancer Genome Atlas (TCGA) was used to explore genomic and clinical features from 1,062 patients. Gene expression data was used to quantitate cytolytic activity and hallmark gene-sets were used for gene set enrichment analysis. An institutional retrospective review was conducted on 155 patients treated with neoadjuvant chemotherapy (NACT). Patient characteristics were summarized by …

Maturation And Substrate Processing Topography Of The Plasmodium Falciparum Invasion/Egress Protease Plasmepsin X, Sumit Mukherjee, Suong Nguyen, Eashan Sharma, Daniel E Goldberg

2020-Current year OA Pubs

The malaria parasite Plasmodium invades a host erythrocyte, multiplies within a parasitophorous vacuole (PV) and then ruptures the PV and erythrocyte membranes in a process known as egress. Both egress and invasion are controlled by effector proteins discharged from specialized secretory organelles. The aspartic protease plasmepsin X (PM X) regulates activity for many of these effectors, but it is unclear how PM X accesses its diverse substrates that reside in different organelles. PM X also autoprocesses to generate different isoforms. The function of this processing is not understood. We have mapped the self-cleavage sites and have constructed parasites with cleavage …

Psychiatry Training In Autism Spectrum Disorder And Intellectual Disability: Ongoing Gaps And Emerging Opportunities, Natasha Marrus, Kathleen A. Koth, Jessica A. Hellings, Rachel Mcdonald, Mcleod Frampton Gwynette, Rebecca Muhle, William D. Lohr, Roma A. Vasa

2020-Current year OA Pubs

Children, adolescents, and adults with autism spectrum disorder and intellectual disability experience high rates of co-occurring psychiatric conditions throughout their lifetime. However, there is a shortage of psychiatrists to treat these populations. We evaluated how much education psychiatrists-in-training receive on how to care for individuals with autism spectrum disorder/intellectual disability. We found that in many psychiatry programs, residents receive limited training experiences in autism spectrum disorder/intellectual disability involving lectures and patient contact and that psychiatry program directors would benefit from more resources to strengthen education in autism spectrum disorder/intellectual disability.

Males exhibit higher incidence and worse prognosis for the majority of cancers, including glioblastoma (GBM). Disparate survival may be related to sex-biased responses to treatment, including radiation. Using a mouse model of GBM, we show that female cells are more sensitive to radiation, and that senescence represents a major component of the radiation therapeutic response in both sexes. Correlation analyses revealed that the CDK inhibitor p21 and irradiation induced senescence were differentially regulated between male and female cells. Indeed, female cellular senescence was more sensitive to changes in p21 levels, a finding that was observed in wildtype and transformed murine …

Glutamine Metabolism Modulates Chondrocyte Inflammatory Response, Manoj Arra, Gaurav Swarnkar, Naga Suresh Adapala, Syeda Kanwal Naqvi, Lei Cai, Muhammad Farooq Rai, Srikanth Singamaneni, Gabriel Mbalaviele, Robert Brophy, Yousef Abu-Amer

2020-Current year OA Pubs

Osteoarthritis is the most common joint disease in the world with significant societal consequences but lacks effective disease-modifying interventions. The pathophysiology consists of a prominent inflammatory component that can be targeted to prevent cartilage degradation and structural defects. Intracellular metabolism has emerged as a culprit of the inflammatory response in chondrocytes, with both processes co-regulating each other. The role of glutamine metabolism in chondrocytes, especially in the context of inflammation, lacks a thorough understanding and is the focus of this work. We display that mouse chondrocytes utilize glutamine for energy production and anabolic processes. Furthermore, we show that glutamine deprivation …

Difference Imaging From Single Measurements In Diffuse Optical Tomography: A Deep Learning Approach, Shuying Li, Menghao Zhang, Minghao Xue, Quing Zhu

2020-Current year OA Pubs

SIGNIFICANCE: "Difference imaging," which reconstructs target optical properties using measurements with and without target information, is often used in diffuse optical tomography (DOT) in vivo imaging. However, taking additional reference measurements is time consuming, and mismatches between the target medium and the reference medium can cause inaccurate reconstruction.

AIM: We aim to streamline the data acquisition and mitigate the mismatch problems in DOT difference imaging using a deep learning-based approach to generate data from target measurements only.

APPROACH: We train an artificial neural network to output data for difference imaging from target measurements only. The model is trained and validated …

2020-Current year OA Pubs

In the POLARIX trial, pola-R-CHP demonstrated improved progression-free survival (PFS) compared to R-CHOP in untreated intermediate- to high-risk DLBCL. We surveyed practicing clinicians regarding their interpretation of POLARIX, including impressions of efficacy, safety, and cost. Of 174 respondents, most from academic centers (82%) in the United States (57%), 70% stated they would not replace R-CHOP with pola-R-CHP due to insufficient PFS difference, lack of overall survival benefit, and excessive cost. Respondents not recommending pola-R-CHP expressed concerns about financial implications for both society and patients. We observed considerable heterogeneity in both study interpretation and plans for real-world implementation of pola-R-CHP.

Fetal Loss In Pregnant Rhesus Macaques Infected With High-Dose African-Lineage Zika Virus, Lauren E. Raasch, Kevin K. Noguchi, Nicole A. Fuhler, Et Al

2020-Current year OA Pubs

Countermeasures against Zika virus (ZIKV), including vaccines, are frequently tested in nonhuman primates (NHP). Macaque models are important for understanding how ZIKV infections impact human pregnancy due to similarities in placental development. The lack of consistent adverse pregnancy outcomes in ZIKV-affected pregnancies poses a challenge in macaque studies where group sizes are often small (4-8 animals). Studies in small animal models suggest that African-lineage Zika viruses can cause more frequent and severe fetal outcomes. No adverse outcomes were observed in macaques exposed to 1x104 PFU (low dose) of African-lineage ZIKV at gestational day (GD) 45. Here, we exposed eight pregnant …

2020-Current year OA Pubs

"Brain-predicted age" quantifies apparent brain age compared to normative neuroimaging trajectories. Advanced brain-predicted age has been well established in symptomatic Alzheimer disease (AD), but is underexplored in preclinical AD. Prior brain-predicted age studies have typically used structural MRI, but resting-state functional connectivity (FC) remains underexplored. Our model predicted age from FC in 391 cognitively normal, amyloid-negative controls (ages 18-89). We applied the trained model to 145 amyloid-negative, 151 preclinical AD, and 156 symptomatic AD participants to test group differences. The model accurately predicted age in the training set. FC-predicted brain age gaps (FC-BAG) were significantly older in symptomatic AD and …

Mass Drug Administration Of Ivermectin, Diethylcarbamazine, Plus Albendazole Compared With Diethylcarbamazine Plus Albendazole For Reduction Of Lymphatic Filariasis Endemicity In Papua New Guinea: A Cluster-Randomised Trial, Moses Laman, Gary J Weil, Et Al.

2020-Current year OA Pubs

BACKGROUND: A single co-administered dose of a triple-drug regimen (ivermectin, diethylcarbamazine, and albendazole) has been shown to be safe and more efficacious for clearing Wuchereria bancrofti microfilariae than the standard two-drug regimen of diethylcarbamazine plus albendazole in clinical trials. However, the effectiveness of mass drug administration with the triple-drug regimen compared with the two-drug regimen is unknown. We compared the effectiveness of mass drug administration with the triple-drug and two-drug regimens for reducing microfilariae prevalence to less than 1% and circulating filarial antigen prevalence to less than 2%, levels that are unlikely to sustain transmission of lymphatic filariasis, in Papua …

2020-Current year OA Pubs

Uncontrolled resection of replication forks under stress can cause genomic instability and influence cancer formation. Extensive fork resection has also been implicated in the chemosensitivity of "BReast CAncer gene" BRCA-deficient cancers. However, how fork resection is controlled in different genetic contexts and how it affects chromosomal stability and cell survival remains incompletely understood. Here, we report a novel function of the transcription repressor ZKSCAN3 in fork protection and chromosomal stability maintenance under replication stress. We show disruption of ZKSCAN3 function causes excessive resection of replication forks by the exonuclease Exo1 and homologous DNA recombination/repair protein Mre11 following fork reversal. Interestingly, …
