Structural And Electrical Remodeling Of The Sinoatrial Node In Diabetes: New Dimensions And Perspectives, Lina T. Al Kury, Stephanie Chacar, Eman Alefishat, Ali A. Khraibi, Moni Nader

All Works

The sinoatrial node (SAN) is composed of highly specialized cells that mandate the spontaneous beating of the heart through self-generation of an action potential (AP). Despite this automaticity, the SAN is under the modulation of the autonomic nervous system (ANS). In diabetes mellitus (DM), heart rate variability (HRV) manifests as a hallmark of diabetic cardiomyopathy. This is paralleled by an impaired regulation of the ANS, and by a pathological remodeling of the pacemaker structure and function. The direct effect of diabetes on the molecular signatures underscoring this pathology remains ill-defined. The recent focus on the electrical currents of the SAN …

Celebrating Hmong: A Minute Ethnography Of Hmong Americans In Minneapolis, Madison Baczuk

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The Hmong people are a culture that originated in Southern China. However, many Hmong people fled to the U.S (among other nations) with the conclusion of the Vietnam war. Like other Asian cultures, the Hmong people are collectivist and give priority to family members of greater age and of the male gender. The Hmong celebrate birth, marriage, and death through sacred rituals and traditions that honor their ancestors. The Hmong language is in danger of extinction due to globalization. Yet, globalization also brings the general public greater knowledge and exposure to the wonderful culture of the Hmong people.

The Cognitive Evolution Of Homo Erectus, Emily Dzhinenko

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Evolutionary cognitive archaeology evaluates the evolution of cognitive advancements through past hominins and artefacts to understand their intellectual capabilities of planning, reasoning, memory, and problem-solving skills up until present day. I will explore cognitive evolution through a literature review of the effects on Homo erectus from their controlled exploitation of fire. Utilization of fire by H. erectus directly impacted their nutritional intake resulting in physiological changes which included increased brain sizes. Larger brains created room for expansion of the dopaminergic system allowing new cognitive abilities to adapt. Results from these adaptations included a more efficient thermoregulatory system and extraversive behaviours …

Grains Of Gold - Excavating The Perils Of Sand Mining, Oleena Chaudhuri

Journal of Environmental Sustainability

The human population and the global economy have been growing rapidly, increasing resource consumption. This paper evaluates the extent to which sand mining has an impact on the environment. Through a case study and regulatory analysis of India, this paper has attempted to underscore the consequences of excessive sand excavation while highlighting the case of the Indian “sand mafia”. This secondary research evaluation finds that mining of sand resources is a common practice that leads to the destruction of the environment which adversely affects commercial and non-commercial living resources. While studies do point out that economic activities requiring sand as …

As a vegetable oil, consisting principally of triacylglycerols, is the major storage form of photosynthetically-fixed carbon in oilseeds which are of significant agricultural and industrial value. Photosynthesis in chlorophyll-containing green seeds, along with photosynthesis in leaves and other green organs, generates ATP and reductant (NADPH and NADH) needed for seed fatty acid production. However, contribution of seed photosynthesis to fatty acid accumulation in seeds have not been well-defined. Here, we report the contribution of seed-photosynthesis to fatty acid production by probing segregating green (photosynthetically-competent) and non-green or yellow (photosynthetically-non-competent) seeds in siliques of an Arabidopsis chlorophyll synthase mutant. Using this …

Insect Pest Management With Sex Pheromone Precursors From Engineered Oilseed Plants, Hong-Lei Wang, Bao-Jian Ding, Jian-Qing Dai, Tara J. Nazarenus, Rafael Borges, Agenor Mafra-Neto, Edgar B. Cahoon, Per Hofvander, Sten Stymne, Christer Löfstedt

Center for Plant Science Innovation: Faculty Publications

Pheromones have become an environmentally friendly alternative to conventional insecticides for pest control. Most current pheromone-based pest control products target lepidopteran pests of high-value crops, as today’s manufacturing processes cannot yet produce pheromones at low enough costs to enable their use for lower-value crops, especially commodity crops. Camelina sativa seeds genetically modified to express (Z)-11-hexadecenoic acid, a sex pheromone precursor of several moth species, provided the oil from which the precursor was isolated, purified and transformed into the final pheromone. Trap lures containing this pheromone were then assessed for their capacity to manage moth pests in the field. Plant-derived pheromone …

Faculty, Staff and Student Publications

The coronavirus disease 2019 (COVID-19) pandemic has caused a dramatic loss of human life and devastated the worldwide economy. Numerous efforts have been made to mitigate COVID-19 symptoms and reduce the death rate. We conducted literature mining of more than 250 thousand published works and curated the 174 most widely used COVID-19 medications. Overlaid with the human protein-protein interaction (PPI) network, we used Steiner tree analysis to extract a core subnetwork that grew from the pharmacological targets of ten credible drugs ascertained by the CTD database. The resultant core subnetwork consisted of 34 interconnected genes, which were associated with 36 …

Evaluation Of An Initiative To Increase Rates Of Exclusive Breastfeeding Among Rural Hispanic Immigrant Women, Naomi E. Pitcock

Dissertations

This project was a retrospective evaluation of the prenatal education component of a multi-component breastfeeding promotion intervention. The educational portion of this program, provided in Spanish using intercultural communication techniques, was designed to increase the number of Hispanic women who choose to initiate breastfeeding, using breast milk exclusively to nourish their newborns. The Hispanic women included in this program were all registered with a local prenatal-care coordination program for low-income women, had routine hospital births (both vaginal and C-section) and elected to participate in the prenatal education class. Data regarding intention to breastfeed and breastfeeding during hospitalization were gathered through …

Cover Cropping: Sensor-Based Estimations Of Biomass Yield And Nutrient Uptake And Its Impact On Sugarcane Productivity, Hector H. Fajardo Duran

LSU Master's Theses

Sugarcane in Louisiana can be harvested for up to three years from one planting. Soil cultivation along sides of established beds is done for weed control and improve fertilizer use efficiency which increases the risk of soil degradation and yield decline. Planting cover crops (CC) is a soil conservation practice and an effective strategy to improve soil health and nutrient recycling. Limited work has been done on remote sensor-based evaluation of the potential nutrient benefits from cover crops and its effect on nutrient cycling on sugarcane systems. This study was conducted to evaluate the effect of two planting methods (broadcast …

Micro Heat Exchanger To Cool Cerebrospinal Fluid For Brain Injury Treatment, Sachin Dahiya

LSU Master's Theses

Hypothermia is accepted as a method to preserve cells and tissue. Clinical evidence shows that administration of hypothermia could lead to neuroprotection after cardiac arrest. Non-invasive methods such as surface cooling devices, drugs and cold liquid ventilation are available to induce hypothermia. These approaches for achieving hypothermia have not been optimized yet. The surface cooling methods are generally slow and may lead to additional thermal shock to the body. Here, we propose a rapid, selective cooling method for the brain using a micro heat exchanger to cool the cerebrospinal fluids (CSF). We designed and 3D printed a U-type heat exchanger …
