Mixed-methods to explore barriers to the use of food security initiatives in a historically black college and university (HBCU).

Background: To assess students' use and perception of the initiatives to tackle food insecurity (FI) in a Texas historically black college and university (HBCU).

Methods: HBCU students > 18 years (288 students). A mixed-methods approach involving an online survey, focus group discussions and key informant interviews were conducted among the students and major stakeholders to evaluate the prevalence of FI, and gain insights into the challenges to accessing, utilizing and effectively implementing food security (FS) initiatives.

Hindrances and Enablers of Healthy Eating Behavior Among College Students in an HBCU: A Qualitative Study.

Research indicates widespread unhealthy eating habits among college students, posing long-term health risks. This study at a Historically Black College and University (HBCU) aimed to explore the perceived obstacles and facilitators to healthy eating among college students, using the social ecological model (SEM). Through focus group discussions and key informant interviews, the study identified several barriers to healthy eating, including challenges in accessing federal food assistance resources, gaps in nutrition knowledge, cost concerns, limited food variety on campus, difficulty accessing grocery stores, and a lack of cooking skills.

Biosensor and machine learning-aided engineering of an amaryllidaceae enzyme.

A major challenge to achieving industry-scale biomanufacturing of therapeutic alkaloids is the slow process of biocatalyst engineering. Amaryllidaceae alkaloids, such as the Alzheimer's medication galantamine, are complex plant secondary metabolites with recognized therapeutic value. Due to their difficult synthesis they are regularly sourced by extraction and purification from the low-yielding daffodil Narcissus pseudonarcissus.

Perception of and risk factors for type 2 diabetes among students attending an upstate New York college: a pilot study.

Background: Detecting early type 2 diabetes (T2D) risk factors may reduce or prevent the development of the disease. We conducted a pilot study to generate preliminary data on the perception of T2D and further determined the prevalence of T2D risk factors among college students at an upstate New York campus.

Methods: Metabolic profiles were available for 44 college students for cross-sectional analysis.

A Pilot Study Evaluating Organochlorine and Organophosphate Pesticide Exposure in Children and Adolescents of Mexican Descent Residing in Hidalgo County, Texas.

Children and adolescents of Mexican descent residing in Hidalgo County (TX) were evaluated for exposure to organochlorine (OC) and organophosphate (OP) pesticides. A convenience sample of 60 participants enrolled in our pilot study. The lipid-adjusted serum concentrations of nine OC metabolites and creatinine-adjusted urinary concentrations of six OP metabolites were measured and compared with data from the Centers for Disease Control and Prevention's Fourth Report on Human Exposure to Environmental Chemicals.

Exposure to galactic cosmic radiation compromises DNA repair and increases the potential for oncogenic chromosomal rearrangement in bronchial epithelial cells.

Participants in deep space missions face protracted exposure to galactic cosmic radiation (GCR). In this setting, lung cancer is a significant component of the overall risk of radiation-exposure induced death. Here we investigate persistent effects of GCR exposure on DNA repair capacity in lung-derived epithelial cells, using an enzyme-stimulated chromosomal rearrangement as an endpoint.

Alcohol-Induced Hepatic Steatosis: A Comparative Study to Identify Possible Indicator(s) of Alcoholic Fatty Liver Disease.

Background: Fatty liver is an early sign of both nonalcoholic and alcoholic fatty liver diseases. Ethanol feeding using a Lieber-DeCarli liquid diet (LD) model which contains 35% fat to rats or mice is a well-established model for alcoholic fatty liver. However, LD diet alone can also induce fatty liver and its differential metabolic profile may be able to differentiate steatosis induced by LD versus LD plus ethanol.

User Perceptions and Reactions to an Online Cancer Risk Assessment Tool: a Process Evaluation of Cancer Risk Check.

Online cancer risk assessment tools, which provide personalized cancer information and recommendations based on personal data input by users, are a promising cancer education approach; however, few tools have been evaluated. A randomized controlled study was conducted to compare user impressions of one tool, Cancer Risk Check (CRC), to non-personalized educational information delivered online as series of self-advancing slides (the control). CRC users (N = 1452) rated the tool to be as interesting as the control (p > .

Pecularities of Bethe-like approximations and long-range-interaction Ising models.

The mean-field approximation and the Bethe approximation are two of the most often used approximations when one wants to obtain approximations of the phase diagrams and the critical temperature of lattice spin systems. Both can and have often been generalized to produce what are known as cluster mean-field and Bethe approximations. Generally, three characteristics are associated with these approximations.
