Correlation Between Neutrophil-To-Lymphocyte Ratio After Percutaneous Coronary Intervention And The Size Of Infarction In Patients With Acute Myocardial Infarction, Mohamed R. Badran

Journal of Medicine in Scientific Research

Background Inflammatory processes have a role in the pathogenesis of acute myocardial infarction (AMI), left ventricular remodeling, and repair. Infarct size (IS) is a strong predictor of prognosis following AMI. Several tools are used to predict IS, but most of them are expensive and inaccessible all the time. So, neutrophil-to-lymphocyte ratio (NLR) as a marker of inflammation is an easy and cheap tool to predict IS. Aim To assess if post-percutaneous coronary intervention (PCI) NLR can predict IS in patients with AMI. Patients and methods The study included 11 125 patients with AMI treated with primary PCI. We used cardiovascular …

Aim To assess the ability of cardiac mechanical and QTc dispersions to identify significant CAD in patients having chest pain with no prior myocardial infarction. Patients and methods We examined 125 patients who had chest pain and evaluated by coronary angiography. They are divided into two groups. CAD group included 75 patients with significant CAD, and control group included 50 patients …

Early Versus Late Intervention In Patients With High-Risk Non-St;-Elevation Myocardial Infarction, Emmanuel Louka Aziz, Mohamed Abbas Morsy

Journal of Medicine in Scientific Research

Introduction With improvements in percutaneous coronary intervention and the advent of novel adjunctive pharmacotherapy agents (such as GP 2b/3a inhibitors, new antiplatelet agents, and intensive statin regimens), the safety and efficacy of early Percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) has improved significantly (1). Therefore, the current guidelines recommend a routine invasive strategy (angiography and revascularization if applicable) (2) in high-risk patients with non-'ST'-elevation ACS (NSTE-ACS). Aim The aim was to compare the results of early versus late intervention in patients with high-risk NSTE myocardial infarction (MI). Patients and methods This study was carried out on 60 patients …

Hypomorphic Brca2 And Rad51c Double Mutant Mice Display Fanconi Anemia, Cancer And Polygenic Replication Stress, Karl-Heinz Tomaszowski, Sunetra Roy, Carolina Guerrero, Poojan Shukla, Caezaan Keshvani, Yue Chen, Martina Ott, Xiaogang Wu, Jianhua Zhang, Courtney D Dinardo, Detlev Schindler, Katharina Schlacher

Faculty, Staff and Student Publications

The prototypic cancer-predisposition disease Fanconi Anemia (FA) is identified by biallelic mutations in any one of twenty-three FANC genes. Puzzlingly, inactivation of one Fanc gene alone in mice fails to faithfully model the pleiotropic human disease without additional external stress. Here we find that FA patients frequently display FANC co-mutations. Combining exemplary homozygous hypomorphic Brca2/Fancd1 and Rad51c/Fanco mutations in mice phenocopies human FA with bone marrow failure, rapid death by cancer, cellular cancer-drug hypersensitivity and severe replication instability. These grave phenotypes contrast the unremarkable phenotypes seen in mice with single gene-function inactivation, revealing an unexpected synergism between Fanc mutations. Beyond …

The regenerative potential of the endometrium is attributed to endometrial stem cells; however, the signaling pathways controlling its regenerative potential remain obscure. In this study, genetic mouse models and endometrial organoids are used to demonstrate that SMAD2/3 signaling controls endometrial regeneration and differentiation. Mice with conditional deletion of SMAD2/3 in the uterine epithelium using Lactoferrin-iCre develop endometrial hyperplasia at 12-weeks and metastatic uterine tumors by 9-months of age. Mechanistic studies in endometrial organoids determine that genetic or pharmacological inhibition of SMAD2/3 signaling disrupts organoid morphology, increases the glandular and secretory cell markers, FOXA2 and MUC1, and alters the genome-wide distribution …

The identification of transcriptomic and protein biomarkers prognosticating recurrence risk after chemoradiation of localized squamous cell carcinoma of the anus (SCCA) has been limited by a lack of available fresh tissue at initial presentation. We analyzed archival FFPE SCCA specimens from pretreatment biopsies prior to chemoradiation for protein and RNA biomarkers from patients with localized SCCA who recurred (N = 23) and who did not recur (N = 25). Tumor cells and the tumor microenvironment (TME) were analyzed separately to identify biomarkers with significantly different expression between the recurrent and non-recurrent groups. Recurrent patients had higher mean protein expression of …

Towards A Biomarker For Acute Arterial Thrombosis Using Complete Blood Count And White Blood Cell Differential Parameters In Mice, Hee Jeong Jang, Dawid Schellingerhout, Jiwon Kim, Jinyong Chung, Dong-Eog Kim

Faculty, Staff and Student Publications

There is no blood biomarker diagnostic of arterial thrombosis. We investigated if arterial thrombosis per se was associated with alterations in complete blood count (CBC) and white blood cell (WBC) differential count in mice. Twelve-week-old C57Bl/6 mice were used for FeCl3-mediated carotid thrombosis (n = 72), sham-operation (n = 79), or non-operation (n = 26). Monocyte count (/µL) at 30-min after thrombosis (median 160 [interquartile range 140-280]) was ~ 1.3-fold higher than at 30-min after sham-operation (120 [77.5-170]), and twofold higher than in non-operated mice (80 [47.5-92.5]). At day-1 and -4 post-thrombosis, compared with 30-min, monocyte count decreased by about …

Structure-Based Regulatory Role For The 5'Utr Of Rcnmv Rna2, Jennifer S H Im, Jasmine R Sheppard, K Andrew White

Faculty, Staff and Student Publications

Red clover necrotic mosaic virus (RCNMV) is a segmented positive-strand RNA virus consisting of RNA1 and RNA2. Previous studies demonstrated that efficient translation of RCNMV RNA2 requires de novo synthesis of RNA2 during infections, suggesting that RNA2 replication is required for its translation. We explored a potential mechanism underlying the regulation of replication-associated translation of RNA2 by examining RNA elements in its 5' untranslated region (5'UTR). Structural analysis of the 5'UTR suggested that it can form two mutually exclusive configurations: a more thermodynamically stable conformation, termed the 5'-basal stem structure (5'BS), in which 5'-terminal sequences are base paired, and an …

Faculty, Staff and Students Publications

Context: Some individuals present with forms of diabetes that are "atypical" (AD), which do not conform to typical features of either type 1 diabetes (T1D) or type 2 diabetes (T2D). These forms of AD display a range of phenotypic characteristics that likely reflect different endotypes based on unique etiologies or pathogenic processes.

Objective: To develop an analytical approach to identify and cluster phenotypes of AD.

Methods: We developed Discover Atypical Diabetes (DiscoverAD), a data mining framework, to identify and cluster phenotypes of AD. DiscoverAD was trained against characteristics of manually classified patients with AD among 278 adults with diabetes within …

Faculty, Staff and Student Publications

Background: Arbuscular mycorrhizal fungi (AMF) are key soil organisms and their extensive hyphae create a unique hyphosphere associated with microbes actively involved in N cycling. However, the underlying mechanisms how AMF and hyphae-associated microbes may cooperate to influence N2O emissions from "hot spot" residue patches remain unclear. Here we explored the key microbes in the hyphosphere involved in N2O production and consumption using amplicon and shotgun metagenomic sequencing. Chemotaxis, growth and N2O emissions of isolated N2O-reducing bacteria in response to hyphal exudates were tested using in vitro cultures and inoculation experiments.

Results: AMF hyphae reduced denitrification-derived N2O emission (max. 63%) …

Real-Time Liver Tumor Localization Via Combined Surface Imaging And A Single X-Ray Projection, Hua-Chieh Shao, Yunxiang Li, Jing Wang, Steve Jiang, You Zhang

Faculty, Staff and Student Publications

Objective. Real-time imaging, a building block of real-time adaptive radiotherapy, provides instantaneous knowledge of anatomical motion to drive delivery adaptation to improve patient safety and treatment efficacy. The temporal constraint of real-time imaging (< 500 milliseconds) significantly limits the imaging signals that can be acquired, rendering volumetric imaging and 3D tumor localization extremely challenging. Real-time liver imaging is particularly difficult, compounded by the low soft tissue contrast within the liver. We proposed a deep learning (DL)-based framework (Surf-X-Bio), to track 3D liver tumor motion in real-time from combined optical surface image and a single on-board x-ray projection.

Approach. Surf-X-Bio performs mesh-based deformable registration to track/localize liver tumors volumetrically via three steps. First, a DL model was built to estimate liver boundary motion from an optical surface image, using learnt motion correlations between the respiratory-induced external body surface and liver boundary. Second, the residual liver boundary motion estimation error was further corrected by a graph neural network-based DL model, using information extracted from a …

Acute graft-versus-host disease (aGVHD) limits the therapeutic benefit of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and requires immunosuppressive prophylaxis that compromises antitumor and antipathogen immunity. OX40 is a costimulatory receptor upregulated on circulating T cells in aGVHD and plays a central role in driving the expansion of alloreactive T cells. Here, we show that OX40 is also upregulated on T cells infiltrating GVHD target organs in a rhesus macaque model, supporting the hypothesis that targeted ablation of OX40+ T cells will mitigate GVHD pathogenesis. We thus created an OX40-specific cytotoxic receptor that, when expressed on human T cells, enables selective …

Applications And Clinical Trial Landscape Using Toll-Like Receptor Agonists To Reduce The Toll Of Cancer, Christian Rolfo, Elisa Giovannetti, Pablo Martinez, Shannon Mccue, Aung Naing

Faculty, Staff and Student Publications

Toll-like receptors (TLRs), which serve as a bridge between innate and adaptive immunity, may be viable treatment targets. TLRs are the first line of defense against microbes and activate signaling cascades that induce immune and inflammatory responses. Patients with "hot" versus "cold" tumors may respond more favorably to immune checkpoint inhibition, and through their downstream effects, TLR agonists have the potential to convert "cold tumors" into "hot tumors" making TLRs in combination with immune checkpoint inhibitors, potential targets for cancer therapies. Imiquimod is a topical TLR7 agonist, approved by the FDA for antiviral and skin cancer treatments. Other TLR adjuvants …

A Comprehensive And Integrative Approach To Mecp2 Disease Transcriptomics, Alexander J Trostle, Lucian Li, Seon-Young Kim, Jiasheng Wang, Rami Al-Ouran, Hari Krishna Yalamanchili, Zhandong Liu, Ying-Wooi Wan

Faculty, Staff and Students Publications

Mutations in MeCP2 result in a crippling neurological disease, but we lack a lucid picture of MeCP2's molecular role. Individual transcriptomic studies yield inconsistent differentially expressed genes. To overcome these issues, we demonstrate a methodology to analyze all modern public data. We obtained relevant raw public transcriptomic data from GEO and ENA, then homogeneously processed it (QC, alignment to reference, differential expression analysis). We present a web portal to interactively access the mouse data, and we discovered a commonly perturbed core set of genes that transcends the limitations of any individual study. We then found functionally distinct, consistently up- and …
