Inter- And Intra-Operator Variations In Manual Segmentation Of Hippocampus From Mri, Benjamin Huber, Napolon Pellumbi, Esmaeil Davoodi-Bojd, Hamid Soltanian-Zadeh

Neurology Articles

Purpose: We evaluate inter- and intra-operator variations in manual segmentation of hippocampus and present their potential sources. Hippocampal atrophy is common in mesial temporal lobe epilepsy (mTLE). Effective diagnosis and treatment of mTLE depends on accurate and efficient segmentation of hippocampus from magnetic resonance imaging (MRI) data. Manual segmentation by expert radiologists remains the gold standard, although automated segmentation methods exist.

Methods: Hippocampus was segmented in MRI of 118 unilateral mTLE patients and 25 non-epileptic subjects (65 males, 78 females; mean age 39 years) by three operators (M1, M2, M3) manually and by three software tools (FreeSurfer, LocalInfo, ABSS) automatically. …

The Genetic Role Of Schizophrenia, Alyson Wilson

Student Research Design & Innovation Symposium

Schizophrenia is a well-known genetic disorder that affects the way a person feels, thinks, and behaves. Individuals with this disease can undergo psychotic, negative, or cognitive symptoms, which are all at a risk of being misdiagnosed. This research was conducted to determine the genes and proteins that are involved in the development of schizophrenia. Not only are people at a risk of developing schizophrenia when they have specific genes and proteins, but mutations of other genes can also cause an increased risk of developing this disease. While schizophrenia is known to be a highly hereditary disease, epigenetics also plays a …

How Urban Agriculture Is Changing The Food System, Kamryn Kohler

Student Research Design & Innovation Symposium

Historically, urban agriculture has been a way to supplement a city’s food supply. As populations continue to rise, society has to find alternative solutions and supplements to industrialized agriculture. Not only does urban agriculture supplement the industrialized agricultural system, but research has shown that cities with prominent urban agriculture programs combat urban blight, increase food access, decrease food insecurity, and limit food deserts. A mixed-method approach was utilized to determine the outcome, including community-based action research, systematic research, and correlational research. While the research is ongoing, it has shown that urban agriculture has impacted the food system in a positive …

The War In Ukraine, Food Security And The Role For Europe, Maksym Chepeliev, Maryla Maliszewska, Maria Filipa Seara E Pereira

Department of Agricultural Economics Faculty Publications

Food-security implications of the war in Ukraine are exacerbated by adverse weather events, spillover effects from the distortion of energy and fertiliser markets, and domestic policies that countries around the world have implemented in pursuit of food security. Estimates suggest that the cumulative effect of these channels in terms of restricting agricultural and food trade is in the order of over 10 times larger, and their cumulative effect on global food supply is on average three times more substantial than the direct agricultural supply disruptions in Ukraine. The latter, however, disproportionally impacts low-income countries that are particularly vulnerable to food …
