Heart disease is the leading cause of death in the United States. The loss of estrogen from menopause puts women at a greater risk of developing heart disease. The purpose of this study is to determine the effects of drinking beetroot juice on measures of blood vessel health and blood pressure. Participants will drink beetroot juice and placebo juice each for one week followed by blood pressure measurements and ultrasound imaging of an artery in the upper arm. A sub-aim of this study is to investigate the effects of estrogen status on blood vessel function between pre- and post-menopausal women.

There are a total of 6 in-person visits to the Clinical Research Center. You will be asked to drink beetroot juice (2 oz) every day for 7 days. Participants will undergo vascular assessments, blood pressure measurements, and blood draws (11 in total for 6 visits).

Adolescence is a critical period during which many important healthhttps://irb.psu.edu/IRB/sd/ResourceAdministration/Project/ProjectEditor?Project=com.webridge.entity.Entity[OID[058ACDEB3E43384D816C7E390C2B83F6]]&Mode=smartform&WizardPageOID=com.webridge.entity.Entity[OID[E4552FC57E491543A6B7FD8268E23FD7]] habits form in humans. However, animal models provide mixed information about habit formation across development and there are relatively few human studies that address differences between habit formation in adolescents and adults. To address this gap, the proposed study will assess differences in habit formation in adolescents and adults as measured by the "Slips of Action" task, which seeks to discriminate between habitual and goal-directed learning of visual stimuli pairings.

There will be one in-person visit lasting about one hour. Visits will begin with informed consent. Participants will complete a computer task where they are asked to learn associations between pictures and then will be tested on the associated pairings. They will also complete questionnaires and cognitive tasks.

We are investigating how the starch from pulse crops (chickpeas, lentils and dry peas) affects the gut microbiome, particularly with regards to the production of butyrate, a microbial metabolite with a number of known health benefits. We are recruiting people from two groups, those that consume a lot of these pulses and those who rarely consume them. These participants will then track their food intake for 48 hours before collecting a fecal sample which they will return to the lab. We will then use these fecal samples to conduct laboratory fermentations with pulse starches processed in a number of different ways to see what factors are important for determining the amount of butyrate that is produced. This will serve as pilot data for designing future human clinical trials.

This is dietary intervention trial that will examine the impact of consuming three different types of resistant starch on the gut microbiome and butyrate levels in normal weight and obese individuals. Participants will consume starch samples daily for 24 weeks, collecting weekly fecal samples that will be returned to the lab. Researchers will analyze the bacterial fermentation products in these samples, particularly butyrate and analyze the microbiome composition. This will allow identification of differences in resistant starch (a dietary fiber) processing between normal weight and obese individuals and will also determine if the three resistant starches tested have differing impacts on the microbiome and butyrate levels.

This study looks at understanding eating behaviors and attitudes toward food in children/adolescents. More specifically the study's goal is to compare those with and without food allergies to gain a better understanding of a possible underlying factor towards certain behaviors. Children and their caregivers will complete a survey composed of a short section on the child's medical history regarding allergies followed with questions in commonly used clinical assessments.

Average global temperatures and the number of heat waves have increased recently. Humans sweat and increase blood flow to the skin to cool their body when they get hot. Older adults (>65 yrs) do not do this as well as younger adults. This makes them at risk for heat-related illnesses. It is important to learn about cooling strategies that will lower body temperature for older adults in the heat. In this study, we will determine if placing your hands and forearms in cold water and/or supplementation with folic acid are effective cooling strategies for older adults resting in the heat.

There will be 4 in-person visits in a hot and humid environment, there will be folic acid supplementation and placebo for 6 weeks each

Poor maternal nutrition is linked to poor birth outcomes. Current vitamin and mineral recommendations in pregnancy are based on limited data mostly from animal models and non-pregnant people. This study seeks to improve our understanding of the amounts of vitamins and minerals that are needed during pregnancy, to improve the health of women and newborns, especially in low-and middle-income countries. Nutrients travel around the body in blood, therefore part of the research is to understand how much blood and the watery component of blood (plasma) increases in pregnancy. This is a collaborative study with George Washington University (lead PI is there). The Penn State team will conduct pilot work to establish a method for measuring plasma volume in 2 phases. In phase 1, nonpregnant will be asked to attend one visit and plasma volume will be measured by injecting indocyanine-green (ICG, a green dye) and hydroxyethyl starch (HES, a form of starch) through an IV in the arm. In phase 2, pregnant women will be asked to attend 2 visits that are 4 weeks apart, but only HES (the starch) will be injected. For both phases (1 and 2), blood draws will occur at each visit and other non-invasive measurements will also be taken (e.g. weight, height, blood pressure). Each visit should take less than 2 hours and will be conducted at the Clinical Research Center in Noll Laboratory on the Penn State campus.

Only 50% of patients with type 1 diabetes (T1D) recover insulin secretion function after 3 months of initial diagnosis, and this phase is called partial remission (PR) of T1D, also called "Honeymoon phase". During this PR phase of T1D, patients recover the ability to secrete more than 50% of their insulin secretion function. This phase of PR typically lasts no longer than 6 or up to12 months, and has been frequently defined as requiring exogenous insulin below 0.5 units per kilogram per day, and hemoglobin A1C is typically below 7.5%. Most recently the use of a coefficient called IDAA1C ≤ 9 has became more accepted as the methodology to determine the development of partial clinical remission of T1D (honeymoon phase). Prior data published by the SEARCH study (national epidemiological study) showed that youth with prolonged honeymoon phase had higher intake of omega -3 fatty acids, vitamin D intake and leucine intake than those youth without prolonged honeymoon phase of T1D. Currently, there are not approved medications to prolong this phase of partial remission of type 1 diabetes, however inducing PR in youth with T1D could potentially decrease the risk of multi-organ damage caused by chronic severe hyperglycemia associated to the chronic hyperglycemia related to T1D.We aim to perform a case- multiple control study between youth with prolonged partial remission phase of T1D after one year of diagnosis, and compare these youths with multiple controls matched by age, gender, race, and puberty stage to study the potential protective factors associated to the development of prolonged partial remission of T1D.

Participants will be approached at their routine Pediatric diabetes clinic appointment.

The prevention of obesity is a far more effective approach than treating obesity after it has developed. Researchers and medical providers need better tools to identify risk factors for developing obesity, so families and their physicians can work to reduce a child's risk. This proposed study tests whether a novel risk score (PACE) is good at predicting if children will develop obesity. The PACE Score combines the measures of sensitivity to portion size, behavior while hungry or craving, loss of control during eating, and eating speed. This study will follow children in middle childhood through four visits, followed by two visits one year later. We will identify the components of PACE as well as biological and environmental factors that may work with or against the PACE factors to predict how children's body composition changes over a year.

Four baseline visits followed by two follow-up visits one year laterChildren will be provided meals at each visitChildren and parents will complete questionnairesChildren will have a DXA scan and an MRI scanChildren will play learning games on the computerChildren will wear an activity monitor for one weekChildren will perform brief and moderate exercise while wearing a heart rate monitor

During the COVID-19 pandemic, Asian Americans have faced a rise in overt racism, with thousands of hate incidents reported. This has had a bigger impact on young Asian American adults, leading to emotional distress and health problems. A theory by Harrell suggests that experiencing racial discrimination can harm mental and physical well-being due to stress. Past studies have shown a connection between racial discrimination stress and health issues like obesity and mental disorders. However, there's a need to understand the cultural and emotional factors involved. This research aims to explore how racial discrimination affects Asian Americans' food choices by looking at stress responses and cultural influences. Using surveys, experiments, psychophysiology, and virtual reality, the study will investigate how cultural identity affects stress reactions and subsequent food decisions after racial discrimination experiences.
