Supply And Distribution Of Flow And Sediment In River And Delta System, Kazi M. Sadid

LSU Doctoral Dissertations

River deltas are valuable ecosystems that have been essential in supporting human populations and the economy across the world for centuries. However, climate change and human activities have caused significant land loss in delta areas. A prime example of a region that has suffered severe land loss is Louisiana in the United States. Coastal restoration is therefore essential for the livelihoods of its residents. To address this issue, the Lower Mississippi River (LMR) channel bar has been regularly dredged to rebuild degraded marsh areas. Additionally, sediment diversions off LMR have been designed to build marsh areas sustainably. This dissertation investigates …

Antioxidant Properties Of Bovine Liver Protein Hydrolysates And Their Practical Application In Biphasic Systems, Betul Arslan, Youling L. Xiong, Ayla Soyer

Animal and Food Sciences Faculty Publications

BACKGROUND: The influence of protein hydrolysate produced from bovine liver protein hydrolysate (LPH) by enzymatic hydrolysis, using Alcalase/Protamex (1:1), on lipid dispersions was investigated. LPH production was optimized to maximize the antioxidant activity (at 45, 50, and 55 °C for 12, 18, and 24 h). Different concentrations of LPHs (1, 3, and 5 mg/g) were added to emulsions and to liposomes. Lipid oxidation level and particle size of the lipid dispersions were monitored for 14 days of storage at 25 °C. RESULTS: Radical scavenging activity and reducing power were the highest at 45 °C after 24 h of hydrolysis. Electrophoresis …

Comments On “Covidx-Net: A Framework Of Deep Learning Classifiers To Diagnose Covid-19 In X-Ray Images”, Sami Lababidi

Sustainable Machine Intelligence Journal

In an early study by (Pan et al., 2020), the authors proposed a deep learning framework; called COVIDX-Net to support radiologists in the process of automatic diagnosis of COVID-19 infection from X-ray images. In this comment, we argue that Pan et al. 's paper include three failings that may impact the performance of models available in COVIDX-Net leading to erroneous results and incorrect conclusions. First, the study lacks a clear and distinct framework, instead employing a conventional approach of training and testing a set of pre-existing deep learning models. Second,the study lies in the utilization of a very small dataset …

Addressing Subject Heterogeneity In Time-Dependent Discrimination For Biomarker Evaluation

Faculty, Staff and Student Publications

Accurate discrimination has been the central goal in identifying biomarkers for monitoring disease progression and early detection. Acknowledging the fact that discrimination accuracy of biomarkers for a time-to-event outcome often changes over time, local measures such as the time-dependent receiver operating characteristic curve and its area under the curve (AUC) are used to assess time-dependent predictive discrimination. However, such measures do not address subject heterogeneity, although the impact of covariates including demographics, disease-related characteristics, and other clinical information on the discriminatory performance of biomarkers needs to be investigated before their clinical use. We propose the covariate-specific time-dependent AUC, a measure …

Internal Medicine Residency

A 67-year-old male, with a history of severe COVID-19 infection and exposure to talc was seen for worsening shortness of breath for months, requiring supplemental oxygen. He was treated for COVID-19 infection and suspected pneumonia with no improvement. His pulmonary function test (PFT) worsened and computed tomography (CT) showing bilateral airspace opacities with ground-glass opacities (GGO), also worsened over time. He underwent bronchoscopy, bronchoalveolar lavage and pathology revealed pulmonary alveolar proteinosis (PAP). He subsequently underwent whole lung lavage (WLL) which significantly improved his crazy paving pattern on CT and was successfully weaned off supplemental oxygen.

An Injectable In Situ Forming Collagen/Alginate/Caso4 Composite Hydrogel For Tissue Engineering Applications: Optimization, Characterization And In Vitro Assessments, Samar A. Salim, Samar A. Salim

Nanotechnology Research Centre

In situ injectable hydrogels are effectively employed to fill irregular cavitary bone defects with initiating bone growth in targeted areas. Herein, an injectable composited hydrogel composed of collagen and alginate cross-linked in situ using different concentrations of calcium sulfate (0.15, 0.3 and 0.6%, wt./v) was synthesized. Recently, CaSO4 is frequently supported as a bone graft material for bone regeneration, owing to its biocompatibility and osteoconductive properties. Moreover, hydroxyapatite (Hap) after salinization-step by (3-Aminopropyl) triethoxysilane (APTES) was incorporated for further enhancing the osteoconductive property of injected hydrogels. All fabricated hydrogels were characterized by SEM, FTIR and XRD analyses. While physiochemical characteristics …

Genomic Analysis Of Seven Mycobacteriophages Identifies Three Novel Species With Differing Phenotypic Stabilities, Laura O'Connell, Aidan Coffey Prof., Jim O'Mahony

Department of Biological Sciences Publications

Recently, case studies have been published regarding the application of mycobacteriophage (MP) therapy (MPT) in patients with multi-antibiotic-resistant infections. A major limitation in the development of MPT is the paucity of therapeutically useful MP. As there are approximately 10,000 MP that have yet to be sequenced, it is possible that characterization of this cohort would increase the repertoire of useful MP. This study aims to contribute to such a strategy, by characterizing a cohort of 7 mycobacteriophages. Sequencing analyses revealed that the MP have unique sequences, and subsequent gene annotation revealed differences in gene organization. Notably, MP LOCARD has the …
