Sleep Patterns & Sleep Problems Vary By Age In Children With Autism, Charles F Reynolds, Matthew Siegel, Briana Taylor Apr 2022

Sleep Patterns & Sleep Problems Vary By Age In Children With Autism, Charles F Reynolds, Matthew Siegel, Briana Taylor

Costas T. Lambrew Research Retreat 2022

Adolescence is a time of increased vulnerability for youth with autism spectrum disorder (ASD).1 • In non-ASD youth, sleep and circadian rhythms demonstrate marked changes during adolescence that delay the biological propensity for sleep.2 • In combination with early school start times, these agerelated changes in sleep and circadian rhythms result in insufficient sleep duration, circadian misalignment, daytime sleepiness, and numerous behavioral and psychiatric problems.3 • Age-related changes in sleep and circadian rhythms, and their relevance for behavioral and psychiatric health have not been examined in youth with ASD.

Staphylococcus aureus is a notorious human pathogen that causes often lethal systemic conditions that are mostly medical device associated biofilm infections. Similarly, coagulase negative staphylococci are emerging as leading pathogen for nosocomial infections owing to their ability to form biofilm on implanted medical equipment. Chronic in nature, these infections are difficult to treat. Such recalcitrance of these infections is caused mainly due to the presence of persister cells, which exhibit transient yet extreme tolerance to antibiotics. Despite tremendous clinical significance, there is lack of studies on persister cells formation among clinical bacterial isolates. Considering the importance of factors influencing persister …

Autografting is the most effective method used for supplementing and replacing bone. Autografting is a risky procedure because of its invasive nature. When performing the procedure of autografting, one needs to remove small sections of bone to use as a stimulant at the fracture site. This study is made to design an alternative method to replace autografting. In our study, we used pig fibula as a model to compare the properties of our novel cement which is Calcium Phosphate based. Calcium Phosphate Cement (CPC) is ideal because it is a biocompatible bone substitute composed of Hydroxyapatite (HA), which constitutes a …

GREAT Day Posters

The search for alternative ways to create a more sustainable and environmentally friendly source of energy, other than fossil fuels, has been ongoing for many years. Particularly, the production of biofuels has become of interest. First generation biofuels were of interest as they curb greenhouse gas emissions, unlike fossil fuels. However, first generation biofuels lead to the increase in food prices as they utilize food sources toward biofuel production, which negatively impacts developing countries. To mitigate this issue, second generation biofuels are a more appealing alternative. Second generation biofuels aim to not affect the food supply, as they use non-human …

Tuna fish plays a significant economic and environmental role and contributes at least $40 billion annually to the global economy, but climate change has been rendering tuna populations particularly vulnerable to rising ocean temperatures and acidification. Recent studies have shown the emerging role of noncoding RNA (ncRNAs) such as piRNA in stress response and transgenerational inheritance. In order to assess the potential role of piRNA in tuna population’s response to climate stress, we use the zebrafish as a laboratory model to identify piRNAs whose steady-state levels change in response to conditions mimicking global climate change stress: elevated temperature, decreased pH …

Fast Photochemical Oxidation And Footprinting Of Proteins Via Trifluoromethyl Radical Chemistry, Elaine Morrow Apr 2022

Fast Photochemical Oxidation And Footprinting Of Proteins Via Trifluoromethyl Radical Chemistry, Elaine Morrow

Honors Theses

Fast photochemical oxidation of proteins (FPOP) is a useful tool in proteomics because of the ability for modifications to occur on the scale of microseconds which reduces the modifications to tertiary and quaternary structure allowing for more accurate labeling of the protein. Labels for FPOP are generated from various radicals in our experiments which include hydroxyl radicals and trifluoromethyl radicals. Hydroxyl radicals are easily generated by using an excimer laser (KrF laser, 248 nm) or a UV flash lamp (as a part of the Fox™ System) by the photolysis of hydrogen peroxide. Trifluoromethyl radicals, however, need hydroxyl radicals to be …

Racial Health And Productivity Inequalities In The United States, Elissia Vecere Apr 2022

Racial Health And Productivity Inequalities In The United States, Elissia Vecere

Honors Theses

Across America, it is frequently seen that there are may differences by race in economic and social outcomes. This variability can be seen in judicial, social, and economic systems. The breakdown of economic systems presenting racial variability can be displayed via workplace statistics. There is a general discrepancy between the workplace statistics represented with Black and White employees. These differences frequently are blamed on the productivity and background education supplied by the employee upon being hired. However, the levels of variation across these two races varies minutely in comparison to the differences in wages supplied. When all factors are kept …

GREAT Day Posters

Biodiversity (biological diversity) refers to the diversity of all life on Earth, including ecosystems and species. Currently, 36 areas globally are classified as biodiversity hotspots, defined as a region that contains high biodiversity levels that are also threatened by human population and development. The specific requirements for this classification follow two criteria: it hosts 1,500 endemic vascular plants, and at most 30% of its area is covered in original native vegetation present. This research maps the history of biodiversity hotspots with respect to changes in human population and land use from 1000 to 2000 CE. Results show that the biodiversity …

GREAT Day Posters

Myrmarachne formicaria is a species of ant-mimicking jumping spider native to Eurasia that was first noticed in the United States in 2001. These spiders get their name from their ant-like body forms and movement of their two forelegs to appear like antennae. They are also sexually dimorphic, with the males having enlarged chelicerae (jaws) that extend out from the front of their face. Males that encounter each other engage in displays that include faceoffs (facing one another and pacing back and forth), putting their abdomens to the side, opening their chelicerae, and even attacking/jabbing at one another. These male displays …

Retrotransposable elements are selfish DNA elements that replicate within a host genome through an RNA intermediate. Long Interspersed Elements (LINEs), found in most eukaryotic genomes, are among the most abundant retrotransposable elements found in the human genome, accounting for over one-third of our DNA. Our study focuses on R2, a LINE element encoded from Bombyx mori (R2Bm) that specifically inserts into the 28S rRNA genes. The R2Bm has been exclusively used to study the biochemical steps by which R2 integrates into the host genome, known as target primed reverse transcription (TPRT). In TPRT, one subunit of the R2Bm, bound to …

GREAT Day Posters

It has been well established that decreases in cellular adhesions are associated with progression of squamous cell carcinomas to a malignant state. We have found that clobetasol treatment of A431 cells results in the initial loss of E-cadherin preceded by the gain of vimentin expression. Our system provides an inducible model to study this process. During clobetasol induced EMT in the A431 cells the expression of vimentin increases, but the cells do not lose expression of their cytokeratin molecules. Using Raman spectroscopy, we can identify key changes in metabolites associated with EMT between the A431 cells that respond to clobetasol …

Zebrafish embryos that are homozygous for gef mutant alleles experience a small-eye phenotype and are hypothesized to have decreased levels of the Chaf1b protein. This could be detected by anti-Chaf1b antibodies in a western blot. This western blot will be performed using Chaf1b morpholino 3 dpf embryos, wild type 3 dpf embryos, and gef mutant embryos 3 dpf. Embryos inoculated with Chaf1b morpholino serve as a negative control. This was then compared to the positive control of wild type zebrafish embryos, whose western blot was expected to have normal levels of Chaf1b. Proteins isolated from a gef mutant were then …

Solitary bees are a vital part of ecosystems due to their role in pollination of crops and native flowering plants. Some solitary bees, mason bees and leafcutter bees, use hollow cavities to rear their brood. Availability of above ground nesting sites is vital to their success. To promote these beneficial bees, people have set out artificial cavities for them to use. Unfortunately, exotic mason bees are outnumbering native mason bees in the eastern United States and may also benefit from these supplemental nest sites. In Spring 2020 boxes of hollow tubes for cavity-nesting bees were established at locations across SUNY …

GREAT Day Posters

Deforestation is increasingly associated with the transmission of zoonotic viruses, such as Malaria in South America and Ebola in Africa. Increasing rates of deforestation may cause viral transmission to accelerate. In this study, I asked how deforestation and other factors may interact to affect transmission of Yellow Fever virus. For example, deforestation in areas with higher precipitation may have different effects on animal hosts and mosquito vectors of the Yellow Fever virus compared to areas with lower precipitation. In addition, more densely-populated countries could have increased transmission compared to less densely-populated countries. Also, the ability to successfully treat viral transmission …

Studies have demonstrated that exposure to cannabis during development impairs cognitive processes in humans, as well as locomotor activity and learning in animals. This extends to pregnant women and those caring for newborns. The legalization of marijuana can confer an underestimation of the effects of the more potent cannabinoids such as tetrahydrocannabinol (THC). This can lead to increased in utero exposure and postnatal exposure via breastfeeding. Newborns can also be affected if maternal care is compromised during an acute high. The current study used VitalView software and cage-top infrared activity monitors to quantify the effects of a range of THC …

Deep-sea inhabitants survive high pressure, limited food availability, lack of sunlight, and cold temperatures. These deep-sea conditions have spurred adaptations that allow organisms to fill an array of niches. For example, distinctive feeding modes and jaw morphologies enable organisms to utilize the food resources available in their environment. Here, we investigate feeding biomechanics in deep-sea fishes across three families of fishes, the rattails (Macrouridae), snailfishes (Liparidae), and cutthroat eels (Synaphobranchidae). Each of these families exist in abundance and occupy important ecological roles in their environment. We compare jaw morphologies and mechanics between families to gain insights into feeding mode, including …
