The internet has become a major source of health information, and the user-generated content found online, especially on social media, makes health misinformation a serious concern (Yang & Beatty, 2016). Two-thirds of U.S. ...
Impact of the NAD+ salvage pathway on the motor system and bioenergetics
(University of Missouri--Columbia, 2023)
Nicotinamide adenine dinucleotide (NAD+) is a metabolite pivotal to numerous cellular functions, including energy metabolism, DNA repair, and protein modification. The majority of NAD+ is generated by the NAD+ salvage ...
Effects of heat stress on leukocyte function and gene expression in lactating dairy cows
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The effects of heat stress in animal agriculture are expected to become more serious as global temperatures continue to increase. Negative effects on production, reproduction...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Family-based treatments for children with mental health, physical health, and developmental disorders often convey secondary benefits to caregivers and siblings who...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems
(University of Missouri--Columbia, 2020)
selected and cultivated for nut production by the University of Missouri - Center for Agroforestry (Columbia, MO, USA). Additionally, it is likely that the bioactive activities of black walnut are correlated with its bioactive constituents including...
The use of pluripotent stem cells as a model for early human placentation
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Throughout gestation, the placenta plays a critical role in ensuring proper development of the fetus. The placenta functions to exchange nutrients, oxygen, and fetal waste...
Role of microRNAs in the legume - rhizobium nitrogen fixing symbiosis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nitrogen is a macronutrient that is critical for plant growth and development because it provides the building blocks of nucleic acids, proteins, chlorophyll, and energy...
Sleep, exercise, and insulin sensitivity
(University of Missouri--Columbia, 2020)
