Authors: Vorob’eva O. V. , Fateeva V. V. 
Published: September 2020

The association between depressive disorder and quality of life of middle-aged patients with cerebral microangiopathy has not been fully investigated.Aim. Study the association between the depression level and quality of life (QOL) in patients with cerebral microangiopathy.Materials and methods. In outpatients 45–59 years old (n = 262, 42% men, 58% women) with cerebral microangiopathy and depression, the level of anxiety was assessed using the HADS-A scale, QOL — using the SF-36 questionnaire. According to the severity of depression (HADS-D subscale), the following were distinguished: group 1 (n = 116) — 8–10 points (subclinical) and group 2 (n = 146) — ≥11 points (clinical). To analyze the data used: t-test, correlation coefficient, logistic regression model; odds ratio (OR) and 95% confidence interval (CI).Results. In group 2, the average anxiety score on the HADS-A scale was 14.3 ± 4.6 points, and for anhedonia was – 10.4 ± 4.2 points, which is statistically significantly higher than in group 1: 10.1 ± 4.2 and 7.1 ± 2.6 points, respectively (p < 0.05). The overall QOL score was statistically significantly lower in group 2: according to the physical component of health, 52.4 ± 26.5 vs. 88.8 ± 43.5 in group 1 (p < 0.05) and psychological component 38.5 ± 19.4 vs. 70.8 ± 35.8 in group 1 (p < 0.05). Depression, anxiety and anhedonia are associated with a negative effect on the overall QOL: r = −0.84 (p < 0.05), r = −0.81 (p < 0.05), r = −0.87 (p < 0.05), respectively. This association does not depend on age, obesity, type 2 diabetes mellitus: OR for depression was 2.1; 95% CI (1.8–2.4), p < 0.05; anxiety — 1.9; 95% CI (1.2–2.2), p < 0.05; anhedonia — 2.3; 95% CI (2.1–2.7), p < 0.05, respectively.Conclusion. Clinically significant depression reduces noticeably QOL. An increase in the severity of affective symptoms leads to a deterioration in both the psychological and physical components of QOL. Decreased QOL does not depend on age, obesity, type 2 diabetes mellitus.

Introduction. Peripartum cardiomyopathy (PPKMP) is a rare cause of heart failure (CHF) in healthy women during pregnancy and within 5 months after delivery.Case report. A 33-year-old female patient, a native of Tajikistan, first developed shortness of breath and edema of the lower extremities at the 35th week of her third pregnancy. Cesarean section was performed at 39 weeks. Symptoms progressed within 3 months of the postpartum period, hepatomegaly, ascites and hydrothorax appeared. Echocardiography revealed heart chambers dilation, reduced left ventricular ejection fraction (26%), diffuse hypokinesis. The diagnosis of PPCM was established. Perindopril, bisoprolol, spironolactone, furosemide, bromocriptine, heparin were prescribed. The severity of HF symptoms decreased significantly during 12 days of treatment.Discussion. PPCM is a diagnosis of exclusion. Myocarditis, dilated and ischemic cardiomyopathy were considered in the differential diagnosis. The factors associated with increased risk of PPCM were age over 30 years, multiparity, preeclampsia. The clinical effect of bromocriptine confirms the diagnosis.

Immunohistochemistry of the Vasopressin Receptor AVPR V2 in Rat Brain
Authors: Clites Garrett A. , Keller Karen Lee 
Published: September 2020

Vasopressin hormone, found in most mammals, plays a key role in the homeostasis of water and solute concentration in the blood. There are three known subtypes of vasopressin receptors, each with unique tissue distributions. Arginine vasopressin receptor 2 (AVPR V2) has been identified in mammals in the kidney, lung, and various regions of the brain. Binding of vasopressin to the AVPR V2 receptor has been associated with antidiuresis and decreased cardiac output as well as various social behaviors in several mammal species. The purpose of this study was to determine whether the AVPR V2 receptor is present in rat brain, and if present, to identify the specific brain region and cell type expressing the receptor. Frozen, preserved rat brain was sectioned on a cryostat and processed with rabbit polyclonal AVPR V2 and biotinylated goat polyclonal secondary antibody to rabbit IgG. Staining of antibody treated sections revealed AVPR V2 receptors were present on Purkinje cell axons and cells bodies in the cerebellum. These data suggest that the cerebellum of rats may be an important regulatory site of vasopressin functions.

Published: September 2020

The efficacy of producing sheep by grazing on agroforestry based pasture in relation to growth, breeding traits, and impacts on the pasture were investigated. Sheep were placed on traditional or agroforestry grazing pasture and experiments determined growth rates, organic material and nitrogen concentrations of the soil, forestry utilization, and female breeding traits. There were no significant differences between the growth traits. There was significantly higher organic material from the agroforestry vs. the traditional pasture. The nitrogen content from the agroforestry without sheep was significantly higher compared to the other plots. The percent of understory cover on the agroforestry plot was significantly less compared to a control. There were no significant differences in sexual receptivity or pregnancy rates in the ewes, but the lambing rates of the agroforestry was significantly higher than the traditional pasture.
The Role of Oxytocin, Vasopressin, and D-Cycloserine in Remediating Social Behavior in Rats with Amygdala Lesions
Authors: Scanlan Kristina Lauren , Gittis Alan , McGovern Robin 
Published: September 2020

Autism is a common neurodevelopmental disorder that affects communication and social behavior. To reduce the social deficits characteristic of autism, the compounds oxytocin, arginine vasopressin, D-cycloserine, and D-cycloserine + oxytocin were explored as therapeutic agents. Twenty-one Long Evans Hooded rats underwent a bilateral amygdala lesion, which reduced the time of social interactions between the pairs of animals. Upon administration of D-cycloserine, the social deficits induced by the lesions were significantly reversed in both sexes. In addition, it was observed that the efficacy of the treatments was affected by the sex of the subjects. Male rats had the largest increase in social behavior when given D-cycloserine. However, female rats experienced the largest reduction in social impairment when administered oxytocin. Thus, sexually dimorphic treatments should be further investigated for individuals with autism spectrum disorders.

Published: September 2020

Purpose: This research aimed at studying perceptions about cholesterol in Hispanics, and uncover, if they were willing to make lifestyle changes because of cholesterol and its effects on health.Methods: Qualitative: Interviews were conducted with five participants from a Northeast Texas community based organization. Quantitative: Pre and post surveys were given to eighty-three different participants, conveniently chosen from the community based organization. A paired sample t-test was used to compare the responses. Results: The qualitative study showed that it was hard for people to make the time to exercise due to busy work schedules and majority of them ate greasy food cooked in lard at home.The quantitative study showed that people were willing to make lifestyle changes after the intervention: They were more likely to consider getting their cholesterol tested at least once a year (p<.000), exercise at least three times a week (p<.000) and eat a balanced diet consisting of fruits and vegetables (p<.000). Conclusion: Participants weren’t clear on the effects of cholesterol on health before the intervention. There was an overwhelming positive response after the intervention where people were willing to make lifestyle changes. These changes included eating a balanced diet, exercising at least three times a week, and getting cholesterol tested at least once a year
Stability Analysis of FitzHugh-Nagumo with Smooth Periodic Forcing
Authors: Massaro Tyler James , Esham Benjamin F. 
Published: September 2020

Alan Lloyd Hodgkin and Andrew Huxley received the 1963 Nobel Prize in Physiology for their work describing the propagation of action potentials in the squid giant axon. Major analysis of their system of differential equations was performed by Richard FitzHugh, and later by Jin-Ichi Nagumo who created a tunnel diode circuit based upon FitzHugh’s work. The resulting differential model, known as the FitzHugh-Nagumo (FH-N) oscillator, represents a simplification of the Hodgkin-Huxley (H-H) model, but still replicates the original neuronal dynamics (Izhikevich, 2010). We begin by providing a thorough grounding in the physiology behind the equations, then continue by introducing some of the results established by Kostova et al. for FH-N without forcing (Kostova et al., 2004). Finally, this sets up our own exploration into stimulating the system with smooth periodic forcing. Subsequent quantification of the chaotic phase portraits using a Lyapunov exponent are discussed, as well as the relevance of these results to electrocardiography.
Effectiveness of Food Sustainability Education among Grade School Students
Authors: Luehr Loran Mary , Smith Sylvia 
Published: September 2020

Increasingly, the human population is having an impact on the environment. Educating younger generations on sustainability issues may make a difference. This project’s goal was to raise awareness and change attitudes toward food sustainability issues by creating an effective education program for elementary age students. The project was a four-week interactive program focusing on local foods, gardening, recycling, and world hunger. Participants included 85 elementary age students from two local schools in southern Illinois. To determine the program effectiveness, a within-subjects, repeated measures design was utilized to compare mean scores of participants. Pre and post-program surveys were completed regarding awareness, attitudes, and behaviors toward the topics taught during the program. PASW (Version 18.0) was used to analyze the data. The level of significance was established at p<0.10 because of the exploratory nature of the research. Results indicated that the program was most effective with fourth grade students. Fourth grade had significant change in understanding world hunger, effects on the world around them, Community Supported Agriculture (CSA) and stores carrying more local foods. Eighth grade had significant change in effects on the world around them and understanding CSA. Sixth grade students had significantly higher mean scores in understanding CSA. The positive results with the youngest age group suggests that food sustainability programs introduced to this age through interactive programs can be effective at changing awareness and attitudes. The lack of positive results with the sixth and eighth grade students should be researched further. Future sustainability projects should focus on finding the most effective hands-on techniques to increase student awareness of food and the environment.
Pancreatic Cancer and Awareness
Authors: Trofemuk John Vince 
Published: September 2020

Pancreatic cancer affects thousands of people every year throughout the world, killing more than ninety-five percent of its victims within the first five years. Life expectancy upon diagnosis is generally only four to six months. There are many risk factors associated with pancreatic cancer, the most prominent of which is a genetic mutation. Specific symptoms indicating pancreatic cancer do not typically appear until it is in stage IV. At this point a cure is nearly impossible. The aim of this paper is to bring to light the risk factors and the general signs and symptoms that are associated with pancreatic cancer. It is hoped that by increasing awareness of the risk factors and educating the public regarding early signs and symptoms we can increase pancreatic cancer detection and cure rates.
Estrogen Differentially Affects Expression of Calcium Handling Genes in Female and Male Adult Cardiomyocytes
Authors: Mu Xiaojing , Harvey Pamela 
Published: September 2020

Premenopausal women have a lower risk of developing heart disease compared with postmenopausal women and age-matched men. However, the debate about whether estrogen is cardioprotective is ongoing due to conflicting results from basic science and clinical trials as well as signaling pathways that make interpretation of effects difficult. Calcium handling in the contracting cells of the heart, the cardiomyocytes, is one of the most important pathways involved in heart function. We sought to determine if calcium-handling genes are regulated by estrogen in a sexually dimorphic manner to explain differences in heart health between men and women. Cardiomyocytes were isolated from the hearts of healthy male and female rats and were treated with different doses of estrogen (300pM, 10nM). Expression of a set of calcium handling genes was then measured to determine the effect of estrogen. Our results demonstrate that estrogen differentially regulates calcium-handling genes in female and male cells, an effect that is also dose-dependent. To our knowledge, this is the first study to examine expression of this comprehensive set of calcium-handling genes in response to estrogen and to consider its effects separately on cardiomyocytes isolated from males and females.
Amyl Nitrites and Sexual Behavior
Authors: Cheng David Tian En 
Published: September 2020

This paper looked into the abuse of inhalable nitrites, mainly amyl nitrites, commonly known by the street name of poppers. This paper compiled several studies of nitrite inhalant abuse and the risk associated with the sexual practices that may concur. The paper explores first, the history and true intentions of nitrite inhalants, then the increasing abuse mainly within the homosexual community, and the legitimacy of the link of nitrites and the HIV/AIDS epidemic. Various studies discussed in the paper will show that there is no legitimate link between poppers increasing the chance of HIV/AIDS but it is the unsafe sexual practices that occur with poppers that lead to various sexually transmitted diseases. The dangers of inhalable nitrites come from legal loopholes, use with other drugs such as Viagra, and the nature of unsafe sexual practices mostly within the homosexual community.
Exploring the Relationship between Trunk Adiposity and Trunk Flexibility
Authors: Ward TaNiqua 
Published: September 2020

Abstract Purpose: The purpose of this study is to examine the relationship between trunk adiposity and trunk flexibility among adults. Methods: A total of 29 participants, male (n=11) and female (n=18) participants between the ages of 19 and 84 years. The participants were recruited from the University of Central Oklahoma daily email news service. The bioelectrical impedance analyzer (BIA) was used to calculate percent body fat and body mass index (BMI). Three circumference measurements were taken on each participant: waist, abdomen, and hips. The two inclinometers were placed on the sacroiliac joint (S1) and thoracic 12 (T12) to measure trunk flexion and extension. Trunk flexibility was measured as the difference between the two reading at full flexion or extension. Results: The Pearson’s Product Moment Correlation was used to analyze the results. There was a significant negative relationship between trunk flexion correlated with abdomen circumference (r= -.49, p= .01) and hip circumference (r= -.39, p= .03). There was a non- significant relationship observed between trunk flexion and WHR (r= -.10, p= .62) and waist circumference (r= -.35, p= .06). There was a non-significant relationship observed between trunk extension and WHR (r= -.07, p= .71), waist circumference (r= .17, p= .38), abdomen circumference (r= .07, p= .71), and hip circumference (r= .29, p= .13). Trunk flexion was not correlated to BMI (r= -.27, p= .15) and body fat percentage (r= -.29, p= .14). A significant relationship was found between trunk extension and BMI (r= .38, p= .04). Trunk extension and body fat percentage (r= .02, p= .92) did not have a significant relationship. Conclusion: Abdomen and hips are most beneficial when measuring circumferences for trunk adiposity. It was found that trunk flexion has a greater relationship with trunk adiposity than trunk extension.
Biodiversity of Sulfate Reducing Bacteria in Mercury-Contaminated Beaver Ponds at Avery Brook
Authors: Kaminsky Rachel Anne , Sirois Sara , Merritt Robert , Katz Laura 
Published: September 2020

Beaver ponds act as mercury sinks, exhibiting favorable conditions for the production of neurotoxic methylmercury by sulfate reducing bacteria (SRBs), a group of bacteria that are characterized by function (sulfate reduction) rather than phylogeny. This study was conducted to explore the diversity of SRB communities inhabiting microenvironments at the sediment-water interface in one beaver pond located on the Avery Brook stream system in the Conway State Forest. Clone libraries were constructed in order to capture some of the diversity of sulfate-reducing bacteria as well as a biogeographic pattern. Though the clone libraries did not reveal a biogeographic pattern, the results showed an unprecedented amount of SRB diversity in all sampled microenvironments.
Mathematics Behind Image Compression

Published: September 2020

This research paper is written in the summer of 2013 while conducting a summer research funded by NYCRI, NASA, NSF, NOAA and Department of Education. The team consists of four members, a faculty, an undergraduate student, a high school teacher and a high school student. The research topic is “image compression” and more precisely the mathematics behind image compression. Image compression is fundamental to NASA and the world’s daily operations. Images are transmitted to NASA from satellites and even Mars, making it very important to send data as efficiently as possible through the low-bandwidth links to these locations. This project focuses its studies in three areas. First, a hands-on mathematical analysis of the singular value decomposition (SVD) compression. Second, on the area of two field experiments that explore the effect of light conditions, shot composition and content, as well as the time of day and other variables on the file sizes of images generated in a digital camera that implements JPEG compression. Third, is about an in-depth study of the JPEG algorithm. In the SVD study, the team analyzed mathematically how matrices are manipulated to return to its equivalent original matrix and the theory about SVD is reinforced by using the software Wolfram Mathematica to compress images from NASA satellites and Mars rover. Mathematica analyzed the file size and timing data for the compression process. In the field experiment, a camera with fixed focus, aperture, and other shooting parameters was used to take pictures at various times of day of the same scene to see how the amount and quality of daylight influenced JPEG’s ability to compress images. The same camera with the parameters still fixed was used to shoot various locations, indoors and outdoors, at the same time of day to see how the content of the photo influenced JPEG file sizes. Finally, the team looked at JPEG’s compression algorithm using Wolfram Mathematica to better understand its efficiency and power, since NASA’s radiation-hardened computer processors are generally not powerful enough to compress images with JPEG. Loosely, the team found that JPEG is best able to compress images with little variation pixel to pixel in color or brightness, and that it provides better looking images at the same file size than SVD compression.
Rocket Science: An Investigation of Magnum ROCKET SCIENCE on Memory, Athletic Performance, Endurance, and Energy
Authors: Conley Nicholas , Campisi Jessica 
Published: September 2020

This small pilot study used a double blind, between-subject, experimental design for the goal of investigating Magnum ROCKET SCIENCE and assess its claim to enhance memory, athletic performance, endurance, and energy. The placebo and the experimental groups performed four separate measures for each of the dependent variables. Memory was measured using a short-term memory test. Athletic performance was measured using repetitive exercise. Endurance was measured through exercise eliciting 70% of VO2 max. Energy was measured through a subjective questionnaire. All the results were recorded and compared to baseline assessments. Once the ten participants (N = 5 per group) completed two full sessions, the results were scored and significant differences were noted: Memory t (7.26) = p < 0.05, Athletic Performance t (6.04) = p < 0.05, Endurance t (6.43) = p < 0.05, and Energy t (4.78) = p < 0.05. There was zero adverse effects experienced with the use of the supplement. It was concluded that the participants taking ROCKET SCIENCE had a significant increase in memory, athletic performance, endurance, and energy when compared to the placebo group. ROCKET SCIENCE was shown to be reasonably safe with no side effects reported and may help athletes reach their individual training goals related to the product’s claims while performing similar exercises.
