The purpose of this study is to examine the psychosocial determinants of baby boomers'-born between 1946 and 1964- intention to choose a menu item featuring plant-based meat alternatives (PBMA) when dining out. The specific objectives are as follows: 1) to identify the baby boomer generation's health-related perceptions about PBMA, and 2) to examine the factors that influence baby boomers' intention to choose a dish featuring PBMA at a restaurant. A total of 174 responses obtained using the Qualtrics panel were analyzed with content analysis and partial least squares structural equation modeling (PLS-SEM).

Exploring Cardiac Exosomal RNAs of Acute Myocardial Infarction.

Background: Myocardial infarction (MI), often a frequent symptom of coronary artery disease (CAD), is a leading cause of death and disability worldwide. Acute myocardial infarction (AMI), a major form of cardiovascular disease, necessitates a deep understanding of its complex pathophysiology to develop innovative therapeutic strategies. Exosomal RNAs (exoRNA), particularly microRNAs (miRNAs) within cardiac tissues, play a critical role in intercellular communication and pathophysiological processes of AMI.

Enhanced Osteocyte Differentiation: Cathepsin D and L Secretion by Human Adipose-Derived Mesenchymal Stem Cells.

Adipose-derived mesenchymal stem cells (ASCs) have the potential to differentiate into bone, cartilage, fat, and neural cells and promote tissue regeneration and healing. It is known that they can have variable responses to hypoxic conditions. In the present study, we aimed to explore diverse changes in the cells and secretome of ASCs under a hypoxic environment over time and to present the possibility of ASCs as therapeutic agents from a different perspective.

Functional sugar-free chewing gum infused with spices bolsters antioxidant capacity and phenolic content of saliva.

Oral and vascular diseases are seemingly disparate conditions, yet individuals with poor oral health are at increased risk for cardiovascular events. Spice-derived bioactive polyphenols with antioxidant functionality may attenuate mechanisms linking the diseases, namely oxidative stress and inflammation. Acknowledging that novel approaches to increase antioxidant intake are warranted, the purpose of this study was to evaluate the influence of two functional sugar-free gums infused with spices on antioxidant capacity and phenolic content of saliva using the oxygen radical absorbance capacity and Folin-Ciocalteu assays, respectively.

A framework for nationwide COVID-19 vaccine safety research in the Republic of Korea: the COVID-19 Vaccine Safety Research Committee.

With the introduction of coronavirus disease 2019 (COVID-19) vaccines, the Korea Disease Control and Prevention Agency (KDCA) commissioned the National Academy of Medicine of Korea to gather experts to independently assess post-vaccination adverse events. Accordingly, the COVID-19 Vaccine Safety Research Committee (CoVaSC) was launched in November 2021 to perform safety studies and establish evidence for policy guidance. The CoVaSC established 3 committees for epidemiology, clinical research, and communication.

A Low Concentration of Citreoviridin Prevents Both Intracellular Calcium Deposition in Vascular Smooth Muscle Cell and Osteoclast Activation In Vitro.

Vascular calcification (VC) and osteoporosis are age-related diseases and significant risk factors for the mortality of elderly. VC and osteoporosis may share common risk factors such as renin-angiotensin system (RAS)-related hypertension. In fact, inhibitors of RAS pathway, such as angiotensin type 1 receptor blockers (ARBs), improved both vascular calcification and hip fracture in elderly.

A Qualitative Analysis of Experiences With Food-Related Activities Among People Living With Parkinson Disease and Their Care-Partners.

The purpose of this qualitative study was to explore factors associated with the ability of people with PD to perform food-related activities (FRAs). Eleven dyads, older adults with Parkinson disease (PD) and their care-partners ( = 22), completed virtual semi-structured interviews guided by the Social Cognitive Theory (SCT) that were independently analyzed by two coders via directed content analysis. The following themes were identified-(1) Personal: perception of a healthy diet, perception of how nutrition influences PD, confidence in following a healthy diet, and barriers to performing FRA; (2) Environmental: previous sources of nutrition information and willingness to changing their diet with a registered dietitian; and (3) Behavioral: modifications to FRA due to food-medication interactions, and skills necessary to maintain a healthy diet.
