Live-Dead Assay On Unlabeled Cells Using Phase Imaging With Computational Specificity, Chenfei Hu, Shenghua He, Young Jae Lee, Yuchen He, Edward M Kong, Hua Li, Mark A Anastasio, Gabriel Popescu

Open Access Publications

Existing approaches to evaluate cell viability involve cell staining with chemical reagents. However, the step of exogenous staining makes these methods undesirable for rapid, nondestructive, and long-term investigation. Here, we present an instantaneous viability assessment of unlabeled cells using phase imaging with computation specificity. This concept utilizes deep learning techniques to compute viability markers associated with the specimen measured by label-free quantitative phase imaging. Demonstrated on different live cell cultures, the proposed method reports approximately 95% accuracy in identifying live and dead cells. The evolution of the cell dry mass and nucleus area for the labeled and unlabeled populations reveal …

Pleiotropic Effects Of Simvastatin And Losartan In Preclinical Models Of Post-Traumatic Elbow Contracture, Michael A David, Alex J Reiter, Chelsey L Dunham, Ryan M Castile, James A Abraham, Leanne E Iannucci, Ishani D Shah, Necat Havlioglu, Aaron M Chamberlain, Spencer P Lake

Open Access Publications

Elbow trauma can lead to post-traumatic joint contracture (PTJC), which is characterized by loss of motion associated with capsule/ligament fibrosis and cartilage damage. Unfortunately, current therapies are often unsuccessful or cause complications. This study aimed to determine the effects of prophylactically administered simvastatin (SV) and losartan (LS) in two preclinical models of elbow PTJC: an

Does Raising The Arms Modify Head Tremor Severity In Cervical Dystonia?, Elizabeth Cisneros, Joel S Perlmutter, Et Al

Open Access Publications

Background: A defining characteristic of dystonia is its position-dependence. In cervical dystonia (CD), sensory tricks ameliorate head tremor (HT). But it remains unknown whether raising the arms alone has the same impact.

Methods: We analyzed data collected from patients enrolled by the Dystonia Coalition. For 120 patients with HT, we assessed how raising their arms without touching their head changed their HT severity.

Results: Forty-eight out of 120 patients exhibited changes in HT severity when raising their arms. These patients were more likely to exhibit decreases in HT severity (N = 35) than increases (N = 13, χ

Discussion: Raising …

Comparative Genomics And Transcriptomics Of 4 Paragonimus Species Provide Insights Into Lung Fluke Parasitism And Pathogenesis, Bruce A. Rosa, Young-Jun Choi, Samantha N. Mcnulty, Hyeim Jung, John Martin, Takeshi Agatsuma, Hiromu Sugiyama, Thanh Hoa Le, Pham Ngoc Doanh, Wanchai Maleewong, David Blair, Paul J. Brindley, Peter U. Fischer, Makedonka Mitreva

Open Access Publications

BACKGROUND: Paragonimus spp. (lung flukes) are among the most injurious foodborne helminths, infecting ∼23 million people and subjecting ∼292 million to infection risk. Paragonimiasis is acquired from infected undercooked crustaceans and primarily affects the lungs but often causes lesions elsewhere including the brain. The disease is easily mistaken for tuberculosis owing to similar pulmonary symptoms, and accordingly, diagnostics are in demand.

RESULTS: We assembled, annotated, and compared draft genomes of 4 prevalent and distinct Paragonimus species: Paragonimus miyazakii, Paragonimus westermani, Paragonimus kellicotti, and Paragonimus heterotremus. Genomes ranged from 697 to 923 Mb, included 12,072-12,853 genes, and were 71.6-90.1% complete according …

Viral-Immune Cell Interactions At The Maternal-Fetal Interface In Human Pregnancy, Elaine L Parker, Rachel B Silverstein, Sonam Verma, Indira U Mysorekar

Open Access Publications

The human decidua and placenta form a distinct environment distinguished for its promotion of immunotolerance to infiltrating semiallogeneic trophoblast cells to enable successful pregnancy. The maternal-fetal interface also successfully precludes transmission of most pathogens. This barrier function occurs in conjunction with a diverse influx of decidual immune cells including natural killer cells, macrophages and T cells. However, several viruses, among other microorganisms, manage to escape destruction by the host adaptive and innate immune system, leading to congenital infection and adverse pregnancy outcomes. In this review, we describe mechanisms of pathogenicity of two such viral pathogens, Human cytomegalovirus (HCMV) and Zika …

Sensitivity Analysis Of Monte Carlo Model Of A Gantry-Mounted Passively Scattered Proton System, Milad Baradaran-Ghahfarokhi, Francisco Reynoso, Michael T Prusator, Baozhou Sun, Tianyu Zhao

Open Access Publications

PURPOSE: This study aimed to present guidance on the correlation between treatment nozzle and proton source parameters, and dose distribution of a passive double scattering compact proton therapy unit, known as Mevion S250.

METHODS: All 24 beam options were modeled using the MCNPX MC code. The calculated physical dose for pristine peak, profiles, and spread out Bragg peak (SOBP) were benchmarked with the measured data. Track-averaged LET (LET

RESULTS: For the physical dose distribution, the MCNPX MC model matched measurements data for all the options to within 2 mm and 2% criterion. The Mevion S250 was found to have a …

Postural Directionality And Head Tremor In Cervical Dystonia, Qiyu Chen, Jeanne P Vu, Elizabeth Cisneros, Casey N Benadof, Zheng Zhang, Richard L Barbano, Christopher G Goetz, Joseph Jankovic, Hyder A Jinnah, Joel S Perlmutter, Mark I Appelbaum, Glenn T Stebbins, Cynthia L Comella, David A Peterson

Open Access Publications

Background: Although abnormal head and neck postures are defining features of cervical dystonia (CD), head tremor (HT) is also common. However, little is known about the relationship between abnormal postures and HT in CD.

Methods: We analyzed clinical data and video recordings from 185 patients enrolled by the Dystonia Coalition. We calculated the likelihood of their HT and HT type ("regular" vs. "jerky") given directionality of abnormal head postures, disease duration, sex, and age.

Results: Patients with retrocollis were more likely to have HT than patients with anterocollis (X

Discussion: We found that HT is more likely for CD patients …

Neuroendocrine Markers Insulinoma-Associated Protein 1, Chromogranin, Synaptophysin, And Cd56 Show Rare Positivity In Adenocarcinoma Ex-Goblet Cell Carcinoids, Chen Yang, Ivan Gonzalez, Lingxin Zhang, Dengfeng Cao

Open Access Publications

Background: Adenocarcinoma ex-goblet cell carcinoid (AdexGCC) was considered a neuroendocrine adenocarcinoma, despite majority of tumor cells being negative for conventional neuroendocrine markers such as chromogranin and synaptophysin. Recently, insulinoma-associated protein 1 (INSM1) has been identified as a novel neuroendocrine marker that is more sensitive than chromogranin, synaptophysin, and CD56 in pulmonary neuroendocrine tumors.

Methods: We studied this marker in conjunction with chromogranin, synaptophysin, and CD56 in 36 appendiceal AdexGCCs (21 primaries, 15 metastatic).

Results: Primary AdexGCCs showed staining for INSM1, chromogranin, synaptophysin, and CD56 in 13/21 (62%), 18/21 (86%), 18/21 (86%), and 9/19 (47%) cases, respectively. However, the mean proportion …

Injury-Induced Actin Cytoskeleton Reorganization In Podocytes Revealed By Super-Resolution Microscopy, Hani Y. Suleiman, Robyn Roth, Sanjay Jain, John E. Heuser, Andrey S. Shaw, Jeffrey H. Miner

Open Access Publications

The architectural integrity of tissues requires complex interactions, both between cells and between cells and the extracellular matrix. Fundamental to cell and tissue homeostasis are the specific mechanical forces conveyed by the actomyosin cytoskeleton. Here we used super-resolution imaging methods to visualize the actin cytoskeleton in the kidney glomerulus, an organized collection of capillaries that filters the blood to make the primary urine. Our analysis of both mouse and human glomeruli reveals a network of myosin IIA-containing contractile actin cables within podocyte cell bodies and major processes at the outer aspects of the glomerular tuft. These likely exert force on …
