Data Driven Classification Of Opioid Patients Using Machine Learning - An Investigation, Saddam Al Amin, Md Saddam Hossain Mukta, Md Sezan Mahmud Saikat, Md Ismail Hossain, Md Adnanul Islam, Mohiuddin Ahmed, Sami Azam

Research outputs 2022 to 2026

The opioid crisis has led to an increased number of drug overdoses in recent years. Several approaches have been established to predict opioid prescription by health practitioners. However, due to the complex nature of the problem, the accuracy of such methods is not yet satisfactory. Dependable and reliable classification of opioid dependent patients from well-grounded data sources is essential. Majority of the previous studies do not focus on the users’ mental health association for opioid intake classification. These studies do not also employ the latest deep learning based techniques such as attention and knowledge distillation mechanism to find better insights. …

The humoral antibody response against Kaposi sarcoma-associated herpesvirus (KSHV) in infected individuals has been characterized demonstrating the latency-associated nuclear antigen (LANA) as the most antigenic KSHV protein. Despite the antigenicity of the protein, specific LANA epitopes have not been systematically characterized. Here, we utilized a bacteriophage T7 library, which displays 56-amino acid KSHV LANA peptides with 28-amino acid overlap (VirScan), to define those epitopes in LANA targeted by antibodies from a cohort of 62 sub-Saharan African Kaposi Sarcoma (KS) patients and 22 KSHV-infected asymptomatic controls. Intra- and inter-patient breadth and magnitude of the anti-LANA responses were quantified at the peptide …

Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. We investigated the genetic diversity and reproductive biology of Colletotrichum graminicola isolates which infect maize by sequencing the genomes of 108 isolates collected from 14 countries using restriction site-associated DNA sequencing (RAD-seq) and wholegenome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms revealed three genetic groups delimited by continental origin, compatible with short-dispersal of the pathogen and geographic subdivision. Intra- and intercontinental migration was observed between Europe and South America, likely associated with the movement of contaminated germplasm. Low …

Cenozoic Extension Of The Lake Tanganyika Rift, East Africa: Structures, Tectonostratigraphy And Paleoenvironmental Reconstruction, Shaidu Shaban

Dissertations - ALL

Active continental rifts are ideal sites for understanding the break-up of continents, and long-lived rift lake environments are known as important reservoirs for endemic communities and biodiversity. The sedimentary fill of extensional continental rifts within the East Africa Rift System (EARS) records a long history of continental extension and variable tropical climate that is unparalleled in its duration and fidelity. Continental extensional basins are sensitive to variations caused by the interplay between tectonics, sedimentary processes, and climate change. However, to discern the sedimentary fill history and its related tectonostratigraphy, as well as for reconstructing past climate changes, high-fidelity data such …

A Coherence-Colored Look Inside Reverse Micelles: Advancing Magnetic Resonance Relaxometry To Characterize Internal Water Pool Dynamics, Alec Beaton

Dissertations - ALL

Traditional data acquisition methods in Nuclear Magnetic Resonance (NMR) collect a subset of the total amount of generated data and discard the rest. In this work, a modified approach toward NMR data acquisition and analysis is formalized and applied in a series of different contexts, ultimately illustrating the utility of collecting and considering this traditionally discarded data. In particular, it is shown that this approach both facilitates and improves NMR data acquisition capabilities at low field (15 MHz), enabling one to overcome challenges arising from, for example, fluctuations in the static magnetic field.With these developments in hand, the dual resonance …

We set out to determine whether the C-terminus (amino acids 481–798) of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α, UniProt Q9UBK2), a regulatory metabolic protein involved in mitochondrial biogenesis, and respiration, is an arginine methyltransferase substrate. Arginine methylation by protein arginine methyltransferases (PRMTs) alters protein function and thus contributes to various cellular processes. In addition to confirming methylation of the C-terminus by PRMT1 as described in the literature, we have identified methylation by another member of the PRMT family, PRMT7. We performed in vitro methylation reactions using recombinant mammalian PRMT7 and PRMT1 at 37, 30, 21, 18, and 4 °C. …

Summary

Background

One challenge in the field of in-vitro fertilisation is the selection of the most viable embryos for transfer. Morphological quality assessment and morphokinetic analysis both have the disadvantage of intra-observer and inter-observer variability. A third method, preimplantation genetic testing for aneuploidy (PGT-A), has limitations too, including its invasiveness and cost. We hypothesised that differences in aneuploid and euploid embryos that allow for model-based classification are reflected in morphology, morphokinetics, and associated clinical information.

Methods

In this retrospective study, we used machine-learning and deep-learning approaches to develop STORK-A, a non-invasive and automated method of embryo evaluation that uses artificial …

Prescribing A Change To The Fda's Drug Labeling Rules After The 21st Century Cures Act, P. Sydney Engle Dec 2022

Prescribing A Change To The Fda's Drug Labeling Rules After The 21st Century Cures Act, P. Sydney Engle

Duke Law Journal

Signed into law in 2016, the 21st Century Cures Act offers new hope to patients by empowering the FDA to expedite review of innovative, potentially lifesaving drugs. But these expedited approvals raise the risk that pivotal drug safety and efficacy data will not arise until after the drug is already on the market. The Cures Act failed to respond to two key aspects of shifting the discovery of safety and efficacy data to the postmarket phase. First, the Cures Act did not correspondingly enhance the FDA’s authority to require manufacturers to generate and disclose postmarket information. Second, it did not …


Acquired And Useful Abilities: Three Essays On Human Capital Development, Rajan Bishwakarma Dec 2022

Acquired And Useful Abilities: Three Essays On Human Capital Development, Rajan Bishwakarma

Economics ETDs

While early childhood circumstances influence the accumulation of skills and abilities, parental and policy responses can magnify or mitigate the effects of childhood circumstances. This work explores the two ideas mentioned above.

Chapter 1 briefs the historical and philosophical roots of the study of human capital and discusses the economic approach to the understanding of child wellbeing before the age of five. Because childhood circumstances influence the accumulation of skills, Chapter 2 estimates the impact of temperature shock during pregnancy on early childhood health. Evidence from Nepal shows that prenatal exposure to high-temperature days impedes child growth; however, the damage …

The Role Of Lncrnas In The Tumor Microenvironment And Immunotherapy Of Melanoma, Wencheng Zhou, Xuewen Xu, Ying Cen, Junjie Chen

Faculty, Staff and Student Publications

Melanoma is one of the most lethal tumors with highly aggressive and metastatic properties. Although immunotherapy and targeted therapy have certain therapeutic effects in melanoma, a significant proportion of patients still have drug resistance after treatment. Recent studies have shown that long noncoding RNAs (lncRNAs) are widely recognized as regulatory factors in cancer. They can regulate numerous cellular processes, including cell proliferation, metastasis, epithelial-mesenchymal transition (EMT) progression and the immune microenvironment. The role of lncRNAs in malignant tumors has received much attention, whereas the relationship between lncRNAs and melanoma requires further investigation. Our review summarizes tumor suppressive and oncogenic lncRNAs …


Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev Dec 2022

Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev

Faculty, Staff and Student Publications

Objective. Determine the extent of sublethal radiation damage (SRD) in a cell population that received a given dose of radiation and the impact of this damage on cell survival. Approach. We developed a novel formalism to account for accumulation of SRD with increasing dose. It is based on a very general formula for cell survival that correctly predicts the basic properties of cell survival curves, such as the transition from the linear-quadratic to a linear dependence at high doses. Using this formalism we analyzed extensive experimental data for photons, protons and heavy ions to evaluate model parameters, quantify the extent …


Quantification Of Phosphatidylethanol In Whole Blood And Dried Blood Spots By Lc-Ms/Ms, Elizabeth Yulianto Dec 2022

Quantification Of Phosphatidylethanol In Whole Blood And Dried Blood Spots By Lc-Ms/Ms, Elizabeth Yulianto

Student Theses

Phosphatidylethanol (PEth) is an alcohol biomarker that provides a longer window of detection than direct alcohol measurement or other common alcohol metabolites, like ethyl glucuronide. PEth has become useful in assessing drinking history, such as for alcohol-withdrawal treatment, organ transplant settings or prenatal alcohol exposure determination. A method was developed and validated to quantify PEth 16:0/18:1 and 16:0/18:2 in whole blood and dried blood spots (DBS) by liquid chromatography tandem mass spectrometry (LC-MS/MS). The whole blood method was applied to 149 samples from pregnant women, elucidating possible prenatal alcohol exposure. Fifty μL whole blood and 12.7 mm whole punches from …

Droughts Reduce Growth Rates And Increase Vulnerability To Increasingly Frequent And Severe Drying Events In An Aquatic Ectotherm, Thomas M. Luhring, Lyndsie S. Wszola, Grant M. Connette, Christopher M. Schalk Dec 2022

Droughts Reduce Growth Rates And Increase Vulnerability To Increasingly Frequent And Severe Drying Events In An Aquatic Ectotherm, Thomas M. Luhring, Lyndsie S. Wszola, Grant M. Connette, Christopher M. Schalk

School of Biological Sciences: Faculty Publications

Many aquatic organisms are experiencing increasingly severe and frequent droughts and drying events. Simultaneously, drought effects are carrying over to non-drought years as ecosystems remain in incomplete states of recovery. Aquatic organisms are thus faced with fewer sequential years under degraded environmental conditions to prepare for increasingly severe droughts and potential drying events. We assessed the effect of droughts and sex on the growth, mass, and mass-dependent estivation potential of long-lived aquatic salamanders (Greater Sirens, Siren lacertina) that estivate during drying events brought on by severe droughts. We calculated growth rates of S. lacertina based on mark–recapture data spanning …

Faculty, Staff and Students Publications

The E3 ligase TNF receptor-associated factor 4 (TRAF4) is frequently overexpressed and closely related to poor prognosis in human malignancies. However, its effect on carcinogenesis and radiosensitivity in oral squamous cell carcinoma (OSCC) remains unclear. The present study found that TRAF4 was significantly upregulated in primary and relapsed OSCC tumor tissues. Depletion of TRAF4 markedly improved the sensitivity of OSCC cells to irradiation (IR) treatment, showing that tumor cell proliferation, colony formation and xenograft tumor growth were reduced. Mechanistically, IR promoted the interaction between TRAF4 and Akt to induce Akt K63-mediated ubiquitination and activation. TRAF4 knockout inhibited the phosphorylation of …
