Medical Diagnostic Value Of Digital Pcr (Dpcr): A Systematic Review, Sophia Nazir

School of Engineering, Computing and Mathematics

Digital polymerase chain reaction (dPCR) is an emerging technique for the absolute quantification of target nucleic acids. dPCR got attention as a precise quantification tool in preclinical research, particularly when used to detect genetic mutations and result in highly precise measurements. In dPCR, the statistic of Poisson distribution was followed for the random distribution of molecules in different partitions, which is essential for dPCR quantification. Amplified target sequences in different partitions are identified by fluorescence and each partition functions as a separate PCR microreactor. Without the need for calibration, the percentage of PCR-positive partitions is sufficient to estimate the concentration …

Articles

Antibiotics have emerged as ground-breaking medications for the treatment of infectious diseases, but due to the excessive use of antibiotics, some drugs have developed resistance to microorganisms. Because of their structural complexity, most antibiotics are excreted unchanged, polluting the water, soil, and natural resources. Additionally, food items are being polluted through the widespread use of antibiotics in animal feed. The normal concentrations of antibiotics in environmental samples typically vary from ng to g/L. Antibiotic residues in excess of these values can pose major risks the development of illnesses and infections/diseases. According to estimates, 300 million people will die prematurely in …

School of Biological and Marine Sciences

We conducted a mesocosm experiment to examine how ocean acidification (OA) affects communities of prokaryotes and eukaryotes growing on single-use drinking bottles in subtropical eutrophic waters of the East China Sea. Based on 16S rDNA gene sequencing, simulated high CO2 significantly altered the prokaryotic community, with the relative abundance of the phylum Planctomycetota increasing by 49%. Under high CO2, prokaryotes in the plastisphere had enhanced nitrogen dissimilation and ureolysis, raising the possibility that OA may modify nutrient cycling in subtropical eutrophic waters. The relative abundance of pathogenic and animal parasite bacteria also increased under simulated high CO2. Our results show …

Here, the presence of C. difficile in 12 wastewater treatment plants (WWTPs) in Western Australia was investigated. Overall, C. difficile was found in 90.5 % (114/126) of raw sewage influent, 48.1 % (50/104) of treated effluent, 40 % (2/5) of reclaimed irrigation water, 100 % (38/38) of untreated …

Global Uncertainty And Economic Growth–Evidence From Pandemic Periods, Deepa Bannigidadmath, M. H. A. Ridhwan, Fiskara Indawan

Research outputs 2022 to 2026

This paper investigates whether global uncertainty predicts economic growth rates using a global sample of 136 countries. We use the panel regression model and find strong evidence that global uncertainty negatively predicts the economic growth rate. Further, the negative impact of global uncertainty on economic growth rates is amplified during pandemic periods versus non-pandemic periods. Our main findings hold after a range of robustness tests.

Dementia is a global public health problem with increasing prevalence and incidence worldwide. The African continent is expected to bear the biggest brunt of the burden of dementia by 2050 because of the rapid demographic changes, including rapid population growth, an increase in life expectancy, and ageing. However, French-speaking Sub-Saharan African (FS-SSA) countries are underrepresented in research on dementia in Africa. While the reasons are diverse and complex, linguistic and cultural barriers to research, disproportionately affect these countries and may be significant factors. Any efforts, therefore, to redress the burden of dementia in Africa must consider the specific demographic, cultural, …

Nicotinamide adenine dinucleotide phosphate oxidase (NOX) may be the most important source of reactive oxygen species (ROS) in periodontal tissues. The pathological mechanism of periodontitis may be related to the increased ROS caused by enhanced NOX activity. The purpose was to investigate the effect of tumor necrosis factor (TNF-α) on inflammatory cytokines and ROS, and the role of NOX-2 in human gingival fibroblasts (HGFs). Materials and methods HGFs were cultured and divided into the normal control group (NC group) and …

Approximation Of Optimal Control Surfaces For The Bass Model With Stochastic Dynamics, Gabriel Nicolosi, Christopher Griffin

Engineering Management and Systems Engineering Faculty Research & Creative Works

The Bass diffusion equation is a well-known and established modeling approach for describing new product adoption in a competitive market. This model also describes diffusion phenomena in various contexts: infectious disease spread modeling and estimation, rumor spread on social networks, prediction of renewable energy technology markets, among others. Most of these models, however, consider a deterministic trajectory of the associated state variable (e.g., market-share). In reality, the diffusion process is subject to noise, and a stochastic component must be added to the state dynamics. The stochastic Bass model has also been studied in many areas, such as energy markets and …

Medication Initiation, Patient-Directed Discharges, And Hospital Readmissions Before And After Implementing Guidelines For Opioid Withdrawal Management, Jillian Zavodnick, Md, Nicolette M. Heinsinger, Angelo C. Lepore, Robert C. Sterling

Department of Medicine Faculty Papers

OBJECTIVES: Rising rates of hospitalization for patients with opioid use disorder (OUD) result in high rates of patient-directed discharge (PDD, also called "discharge against medical advice") and 30-day readmissions. Interdisciplinary addiction consult services are an emerging criterion standard to improve care for these patients, but these services are resource- and expertise-intensive. A set of withdrawal guidelines was developed to guide generalists in caring for patients with opioid withdrawal at a hospital without an addiction consult service.

METHODS: Retrospective chart review was performed to determine PDD, 30-day readmission, and psychiatry consult rates for hospitalized patients with OUD during periods before (July …
