2020-Current year OA Pubs

PURPOSE: Many cancers lack argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme of arginine biosynthesis. This deficiency causes arginine auxotrophy, targetable by extracellular arginine-degrading enzymes such as ADI-PEG20. Long-term tumor resistance has thus far been attributed solely to ASS1 reexpression. This study examines the role of ASS1 silencing on tumor growth and initiation and identifies a noncanonical mechanism of resistance, aiming to improve clinical responses to ADI-PEG20.

EXPERIMENTAL DESIGN: Tumor initiation and growth rates were measured for a spontaneous Ass1 knockout (KO) murine sarcoma model. Tumor cell lines were generated, and resistance to arginine deprivation therapy was studied in vitro and …

Graph Modeling For Openflow Switch Monitoring, Ali Malik, Ruairí De Fréin

Articles

Network monitoring allows network administrators to facilitate network activities and to resolve issues in a timely fashion. Monitoring techniques in software-defined networks are either (i) active, where probing packets are sent periodically, or (ii) passive, where traffic statistics are collected from the network forwarding elements. The centralized nature of software-defined networking implies the implementation of monitoring techniques imposes additional overhead on the network controller. We propose Graph Modeling for OpenFlow Switch Monitoring (GMSM), which is a lightweight monitoring technique. GMSM constructs a flow-graph overview using two types of asynchronous OpenFlow messages: packet-in and flow-removed, which improve monitoring and decision making. …

Development Of A Group Contribution Method To Predict The Aqueous-Phase Reactivities Of Hydrated Electrons With Organic Compounds, Rose Daily, Daisuke Minakata

Michigan Tech Publications, Part 1

Hydrated electrons produced in aqueous-phase advanced reduction processes (ARPs) effectively destroy oxidized forms of environmentally relevant organic contaminants, including alkyl halides. Although the rate constants of hydrated electrons with various organic compounds have been experimentally measured and compiled in the literature, no mechanistic prediction tools have been developed. Given that numerous organic compounds are used in commercial production, a prediction tool for the fate of organic compounds in the aqueous-phase ARPs will be useful. This study focused on developing a group contribution method for hydrated electrons (GCMe) to predict the second-order rate constants with aliphatic and aromatic compounds. The GCMe …

Nanoformulations Of Essential Oils Extracted From Pistacia Lentiscus And Boswellia Sacra And Investigation Of Their Anticancer, Antimicrobial, And Antioxidant Activities., Obaydah Abd Alkader Alabrahim

Theses and Dissertations

Essential oils (EOs) obtained from natural sources have shown promising biological and therapeutical properties such as anticancer, antimicrobial, and antioxidant activities, attributing to their high content of a variety of bioactive components. However, EOs’ therapeutic properties are limited by their low stability, poor bioavailability, high volatility, and low targeting ability. Therefore, the encapsulation and nanoformulation of EOs can maximize their therapeutical efficiency and physicochemical properties while overcoming their undesirable side effects and drawbacks. EOs extracted from the resins of Pistacia Lentiscus var. Chia (P.oil) and Boswellia Sacra (B.oil) are two promising EOs that have shown great therapeutic potential. P.oil was …

Placebo Effects Of Transcranial Direct Current Stimulation On Motor Skill Acquisition, Nicole K. Haikalis, Andrew Hooyman, Peiyuan Wang, Ayoub Daliri, Sydney Y. Schaefer

Physical Therapy Faculty Articles and Research

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique used in neurorehabilitation to enhance motor training. However, its benefits to motor training can be difficult to reproduce across research studies. It is possible that the observed benefits of tDCS are not directly related to the intervention itself but rather to the brain-mind responses elicited by the treatment context, commonly known as a placebo effect. This study investigated the presence of a placebo effect of tDCS on motor training and explored potential underlying factors. Sixty-eight participants who were right-handed were randomly assigned to active tDCS, sham tDCS, or a …

Compass: Joint Copy Number And Mutation Phylogeny Reconstruction From Amplicon Single-Cell Sequencing Data, Etienne Sollier, Jack Kuipers, Koichi Takahashi, Niko Beerenwinkel, Katharina Jahn

Faculty, Staff and Student Publications

Reconstructing the history of somatic DNA alterations can help understand the evolution of a tumor and predict its resistance to treatment. Single-cell DNA sequencing (scDNAseq) can be used to investigate clonal heterogeneity and to inform phylogeny reconstruction. However, most existing phylogenetic methods for scDNAseq data are designed either for single nucleotide variants (SNVs) or for large copy number alterations (CNAs), or are not applicable to targeted sequencing. Here, we develop COMPASS, a computational method for inferring the joint phylogeny of SNVs and CNAs from targeted scDNAseq data. We evaluate COMPASS on simulated data and apply it to several datasets including …

A Multidimensional Connectomics- And Radiomics-Based Advanced Machine-Learning Framework To Distinguish Radiation Necrosis From True Progression In Brain Metastases, Kristin J Redmond, Lawrence R Kleinberg

Indonesian Journal of International Law

Plastic is a significant portion of marine debris, ranging from 60% to 80%. Historically, ships have been a major contributor to plastic pollution in the ocean, followed by Indonesia, which is acknowledged as the second-largest originator. Global efforts to combat marine pollution, including plastic waste, have been undertaken through international agreements like MARPOL Annex V. This agreement has mandated countries to establish suitable port facilities for ship-generated wastes. However, an assessment of Indonesian ports indicated insufficient compliance with environmental management standards, particularly in waste handling.

Progenitor human nasal epithelial cells (hNECs) are an essential cell source for the reconstruction of the respiratory pseudostratified columnar epithelium composed of multiple cell types in the context of infection studies and disease modeling. Hitherto, manual seeding has been the dominant method for creating nasal epithelial tissue models through biofabrication. However, this approach has limitations in terms of achieving the intricate three-dimensional (3D) structure of the natural nasal epithelium. 3D bioprinting has been utilized to reconstruct various epithelial tissue models, such as cutaneous, intestinal, alveolar, and bronchial epithelium, but there has been no attempt to use of 3D bioprinting technologies …

Self-Immolative Hydrogels With Stimulus-Mediated On-Off Degradation., Jue Gong, Aneta Borecki, Elizabeth R Gillies

Chemistry Publications

Hydrogels are of interest for a wide range of applications from sensors to drug delivery and tissue engineering. Self-immolative polymers, which depolymerize from end-to-end following a single backbone or end-cap cleavage, offer advantages such as amplification of the stimulus-mediated cleavage event through a cascade degradation process. It is also possible to change the active stimulus by changing only a single end-cap or linker unit. However, there are very few examples of self-immolative polymer hydrogels, and the reported examples exhibited relatively poor stability in their nontriggered state or slow degradation after triggering. Described here is the preparation of hydrogels composed of …

Real-Time Spatial Interference Removal And Maximum Ratio Combining In Communication Systems, Adam Gary Whipple

Theses and Dissertations

Radio frequency interference (RFI) is undesired and commonplace. Using a subspace projection method to spatially remove the interference from a phased array system gives results of a 30 dB interference null rejection (INR). Unmanned systems have been developed to observe underwater activity and communicate their observations to passing aircraft. These systems are currently limited by their use of a single transmitter. The uplink can be improved by using a dual-antenna beam steering approach to maximize the signal-to-noise ratio (SNR) the aircraft receives. This approach demonstrates an increase in SNR of 3 dB when compared to a single transmitter.
