Investigating the Role of Near-Infrared Spectroscopy in Neonatal Medicine
No full textAbstractNear-infrared spectroscopy (NIRS) is a clinical tool that provides a bedside method of noninvasively measuring continuous, “real-time” oxygen consumption and monitoring for potential ischemia of somatic tissues, particularly the brain, kidneys, and intestine in neonates. Although the concept of NIRS seems promising, its implementation into clinical practice has been inconsistent for various reasons, including difficulty in interpreting regional oxygen saturation (rSO2), the wide variation in types of NIRS monitors and probes, the cost of new equipment, different monitoring modalities, large discrepancies in both intra- and interindividual use, a lack of defined universal normative values, and little to no data on outcomes or potentially harmful interventions made based on rSO2 readings. We combine findings from previously published informational articles and studies on the use of NIRS in neonatal medicine to provide a comprehensive overview of this tool and identify potential indications for clinical use.</jats:p

No Pressure! : Finding Sober Social Environments at SUNY Cortland
No full textOften times this new freedom feels like a call to do things we know we shouldn’t do or couldn’t do before. The reality is everyone (kids, teens, and adults) can struggle with willpower and social pressure and its much healthier to live your college years with intention, not carelessness. I know students who hadn’t touched drugs or alcohol before college and ended up with addictions because their friends,fraternities/sororities, roommates, or teammates pressured them or because they felt a strong urge to spite their parents (or their rules) by being reckless.https://digitalcommons.cortland.edu/cor101posters/1133/thumbnail.jp
Optimizing Hydroponic Lettuce Yield: Evaluation of Potassium Source and Concentration with Plant Imaging
No full textControlled Environment Agriculture (CEA) is an expanding industry in the United States. Lettuce (Lactuca sativa) possesses considerable economic importance as one of the foremost leafy vegetables worldwide in terms of financial value for production in CEA. Rapid growth rate, high yield, and potential return further enhance its suitability for cultivation within CEA. Pursuing optimal and sustainable nutrient concentrations for crops in CEA is a continuous requirement for an expanding industry. This study is set to investigate the impact of different potassium (K) sources and concentrations on 'Green Oakleaf' lettuce growth. The K concentration within the Virginia Tech base hydroponic lettuce fertilizer was increased,1x, 2x, and 3x the normal rates of K ppm, through the addition of potassium chloride (KCl) or potassium sulfate (K2SO4). To account for rising electrical conductivity (EC), due to the increase of K, KCl treatments were recreated with standardized EC through the addition of Sodium Chloride (NaCl). The Spatially and Mechanically Accurate Robotic Table (SMART) in an indoor space was utilized to cultivate and image plant growth over time through pixel count. Growth index and chlorophyll content were recorded weekly, while the fresh weight and dry weight of shoots were recorded at harvest. The KCl treatment with the highest concentration,4x K ppm, as well as those with standardized EC, led to reduced yield when compared to other treatments. All K2SO4 treatments showed no difference in growth when compared to the base solution. K source and concentration, as well as fertilizer EC, were all identified as factors influencing the impact of fertilizers on the optimization of lettuce yield.Master of Science in Life SciencesControlled Environment Agriculture (CEA) is a growing industry in the U.S., and lettuce is one of the most important leafy vegetables globally in terms of economic value. As the industry expands, finding the best and most sustainable nutrient levels for crops is essential. This study explored how different types and amounts of potassium (K) in fertilizers affect the growth of 'Green Oakleaf' lettuce. Potassium levels in the base fertilizer were increased to 1x, 2x, and 3x the normal amount using either potassium chloride (KCl) or potassium sulfate (K₂SO₄). The study measured various growth factors like chlorophyll content, plant weight, and plant image pixel counts. It found that higher levels of potassium chloride (KCl) negatively impacted plant growth, while potassium sulfate (K₂SO₄) did not have the same effect. The research also showed that adding sodium chloride (NaCl) increased the salt content, measured by electrical conductivity (EC), in the fertilizer, which reduced lettuce growth. The findings suggest that high fertilizer ECs, not potassium itself, were the main cause of poor plant growth. Overall, the study identified potassium source and concentration, as well as fertilizer EC levels, as important factors in optimizing fertilizer for lettuce growth
Dwarf Tomatoes in an Indoor Vertical System
No full textAn experiment was conducted to evaluate the potential of producing dwarf tomatoes (Solanum lycopersicum L.) in an indoor vertical system. Cultivars 'Micro Tom', 'Jochalos', and 'Venus' were grown under the three daily light integral (DLI) levels of 16.9, 22.7, and 27.9 mol·m-2·day-1. Cultivar had an effect on height, with Jochalos being the tallest. Plants grown under 27.9 mol·m-2·day-1 were the shortest. The time of first flower was affected by cultivar, appearing earliest in Micro Tom. Regarding DLI, the first flower was earliest in plants under 22.7 and 27.9 mol·m-2·day-1. The time of first harvest was only affected by cultivar, in which Micro Tom was earliest. There was an interaction effect for the total and marketable fruit count harvested. Micro Tom had the highest overall number of fruits harvested amongst cultivars, and Micro Tom grown under 22.7 and 27.9 mol·m-2·day-1 had more total and marketable fruit counts than those grown under 16.9 mol·m-2·day-1. There was no interaction effect for fruit weight harvested. The effect of cultivar differed between the total and marketable fruit weights harvested, but Jochalos produced the highest weights in both. The effect of DLI was the same for total and marketable fruit weights harvested, with plants under 22.7 and 27.9 mol·m-2·day-1 having the highest weights. Cultivar had an effect on fruit Brix, with Micro Tom fruit having the lowest Brix and Jochalos fruit having the highest Brix. The effect of DLI resulted in fruits produced by plants under 27.9 mol·m-2·day-1 having the highest Brix and fruits produced by plants under 16.9 mol·m-2·day-1 having the lowest. Based on these results, there is potential for dwarf tomatoes to be grown in vertical farm systems.Master of Science in Life SciencesAn experiment was conducted to evaluate the potential of producing dwarf tomatoes (Solanum lycopersicum L.) in an indoor vertical system.

Effects of conditionally essential fatty acid supplementation on neural and immune development in the young pig
No full textDSpace SAF Submission Ingestion Package generated from Vireo submission #15835 on 2021-03-04 at 16:19:21Arachidonic acid (ARA; 20:4n-6) and docosahexaenoic acid (DHA; 22:6n-3) are long-chain polyunsaturated fatty acids (LCPUFA) naturally present in human breast milk (HM) and routinely supplemented in infant formula (IF). In IF-fed infants, the inclusion of preformed ARA and DHA is shown to yield more similar tissue FA accretion, cognitive and visual development, and immune response to that of a breastfed infant. Historically, these LCPUFA have been added together, and the physiological responses to independent ARA and DHA supplementation are poorly understood. Additionally, while ARA and DHA forms, including triglyceride (TG) and phospholipid, are known to influence bioavailability and tissue accretion, little is known about the use of these LCPUFA as free fatty acid (FFA) during early development. Using the young pig model, two experiments were conducted to help to fill these knowledge gaps.
The first experiment explored the impact of independent and combined ARA and DHA supplementation. Intact male pigs received one of four dietary treatments (N = 12 per treatment) from postnatal day 2 to 30 with the following target ARA/DHA levels, as a percent of total FA: CON (0.00/0.00), ARA (0.80/0.00), DHA (0.00/0.80), and ARA+DHA (0.80/0.80). Tissue FA accretion, immune response, sleep and motor activity, and myelin thickness in the corpus callosum were evaluated. There were no differences in intake or growth between dietary groups, nor did supplementation differentially affect immune response or myelination outcomes. DHA supplementation alone increased brain DHA, but decreased ARA compared with other groups, while ARA alone increased brain ARA compared with all other groups but did not affect brain DHA compared with CON. The combined ARA+DHA increased brain DHA levels but did not affect brain ARA levels compared with the CON. Pigs fed ARA or ARA+DHA also exhibited higher levels of activity than those fed CON or DHA, and the inclusion of ARA and DHA alone induced differences in time spent asleep compared with CON and ARA+DHA. Together, these data support the case for ARA inclusion when DHA is supplemented in IF to support neurodevelopment and brain ARA accretion. The second study investigated the safety and efficacy of novel sodium and potassium salts of ARA derived from M. alpina oil (Na-ARA and K-ARA), both of which dissociate to Na+/K+ and FFA upon contact with water. Male and female pigs were randomized to one of four dietary treatments (N = 16 per treatment) from postnatal day 2 to 23. ARA and DHA were included as either TG or salt form at the following target ARA/DHA concentrations, as percent of total FA: TT (0.47 TG/0.32 TG), NaT (0.47 Na-salt/0.32 TG), KT (0.47 K-salt/0.32 TG), Na0 (0.47 Na-salt/0.00), and NaNa (0.47 Na-salt/0.32 Na-salt). Overall, the inclusion of ARA and DHA in salt form did not affect growth performance, liver histology, or substantially influence hematological outcomes compared with the TG forms. Bioequivalence assessments confirmed both Na-ARA and K-ARA were 100% bioequivalent to the TG-ARA based on ARA accretion in the cerebral cortex and retinal tissues. These findings demonstrate that the use of these novel FA salts in the young pig was both safe and nutritionally bioequivalent to TG-ARA for critical neural tissues. Overall, the results from these studies demonstrate the importance of balancing dietary ARA and DHA supplementation in IF to support structural and functional brain development, as well as confirm the safety of novel lipid forms of ARA and DHA for use in IF.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-12-01The student, Kaylee Hahn, accepted the attached license on 2020-10-14 at 16:49.The student, Kaylee Hahn, submitted this Thesis for approval on 2020-10-14 at 18:27.This Thesis was approved for publication on 2020-10-16 at 09:59.Made available in DSpace on 2021-03-05T21:40:40Z (GMT).
