Among different age groups, middle-aged individuals are particularly susceptible to obesity, with a 22% higher risk of all-cause mortality. However, the underlying mechanisms remain unclear. In this study, we identify adipose progenitor cells (APCs) in the white adipose tissue (WAT) of middle-aged subjects as potential causes of midlife obesity. Specifically, the extracellular vesicles (EVs) derived from APCs display an impaired ability to mitigate the inflammaging of adipose tissue macrophages (ATMs) in middle-aged individuals. Mechanistically, these EVs, lacking miR-145-5p, fail to suppress the expression of L-selectin in ATMs, thereby facilitating their M1 program via the NF-κB signaling pathway. In contrast, EVs …

An Exploration Of The Experiences Of Perinatal Depression And Anxiety Among Pregnant And Parenting Adolescents In The Tampa Bay Area Of Florida, Olajumoke Adetoun Ojeleye

USF Tampa Graduate Theses and Dissertations

Perinatal depression (PND) and perinatal anxiety (PNA) are increasing among pregnant and parenting adolescents (PPAs), with PNA often underrecognized. This leads to significant socioeconomic costs and adverse maternal consequences if untreated. Hence, this dissertation explores the experiences of PND and PNA among PPAs, focusing on their knowledge gaps, perception, mental health needs, care preferences, and access to PMH care. The research employs a qualitative design (free-listing and in-depth interviews) to gather participant insights. Key findings reveal that many PPAs possess limited knowledge about PNA when compared to PND. Lack of support from partners, family, and peers emerged as the topmost …

Childhood obesity is a global epidemic and a serious issue for children and adolescents in the United States. Despite recognition of its dangers, obesity remains a public health concern, with both genetic and environmental factors contributing to its prevalence. Of particular concern is the higher obesity rates among Hispanic children, who face disproportionately significant psychological and physical health risks. Using the theory of planned behavior, this study aimed to investigate the lack of knowledge regarding gender differences in weight perceptions and intentions, the relationship between physical activity and weight perception, and the role each may play in obesity among Hispanic …

Emerging Clostridioides Difficile Ribotypes Have Divergent Metabolic Phenotypes, Colleen K Ardis, Kevin W Garey, Jennifer K Spinler, Robert A Britton

Faculty, Staff and Students Publications

Clostridioides difficile is a gram-positive spore-forming pathogen that commonly causes diarrheal infections in the developed world. Although C. difficile is a genetically diverse species, certain ribotypes are overrepresented in human infections, and it is unclear if metabolic adaptations are essential for the emergence of these epidemic ribotypes. To identify ribotype-specific metabolic differences, we therefore tested carbon substrate utilization by 88 C. difficile isolates and looked for differences in growth between 22 ribotypes. As expected, C. difficile was capable of growing on a variety of carbon substrates. Further, C. difficile strains clustered by phylogenetic relationship and displayed ribotype-specific and clade-specific …

Identification Of Lysosomal Lipolysis As An Essential Noncanonical Mediator Of Adipocyte Fasting And Cold-Induced Lipolysis, Yu-Sheng Yeh, Trent D. Evans, Mari Iwase, Se-Jin Jeong, Arick Park, Ali Ghasemian, Borna Dianati, Ali Javaheri, Et Al.

2020-Current year OA Pubs

Adipose tissue lipolysis is the process by which triglycerides in lipid stores are hydrolyzed into free fatty acids (FFAs), serving as fuel during fasting or cold-induced thermogenesis. Although cytosolic lipases are considered the predominant mechanism of liberating FFAs, lipolysis also occurs in lysosomes via lysosomal acid lipase (LIPA), albeit with unclear roles in lipid storage and whole-body metabolism. We found that adipocyte LIPA expression increased in adipose tissue of mice when lipolysis was stimulated during fasting, cold exposure, or β-adrenergic agonism. This was functionally important, as inhibition of LIPA genetically or pharmacologically resulted in lower plasma FFAs under lipolytic conditions. …

The Advanced Strategies Of Human And Donor Milk Fortification And Its Effect On Long-Term Outcome In Preterm Babies, Ashwini Lakra, Mahaveer Singh Lakra, Ishani Arora, Heena Bhandekar, Amar Taksande, Roshan Prasad, Mayur Wanjari

Chulalongkorn Medical Journal

Poor growth in intrauterine and extrauterine life and inadequate protein supplementation in babies during the first weeks of premature babies are linked to long-term growth failure and poor brain development. The calorie requirements of premature newborns cannot always be fulfilled, even with routine and traditional fortification. This is because traditional fortification procedures rely on the presumed well-known composition of human milk rather than the calculated one. The protein content of mothers' milk of preterm babies varies, decreases with breastfeeding duration, and differs with donor human milk being preserved in milk banks for a long duration. Newer fortification techniques are needed …

The Perceived Benefits Of And Barriers To Open-Water Swimming: A Mixed-Methods Examination, David Elliott Ph.D, Mark A. Christie Ph.D

International Journal of Aquatic Research and Education

This study set out to determine the perceived benefits of, and barriers to, open-water swimming (OWS). Adopting a mixed-methods approach, six hundred and sixty-five open-water swimmers responded to an online survey consisting of the Exercise Benefits and Barriers Scale (EBBS) and a series of open-ended questions. Data from the EBBS revealed the strongest perceived benefits to be ‘Psychological Outlook’ and ‘Life Enhancement.’ In terms of barriers, those presented in the EBBS received low ratings with only ‘Physical Exertion’ considered as being somewhat problematic. Content analysis performed on the open-ended responses showed social aspects, mental well-being, and connection to nature as …

Investigation Of Dynamic Regulation Of Tfeb Nuclear Shuttling By Microfluidics And Quantitative Modelling, Iacopo Ruolo, Sara Napolitano, Lorena Postiglione, Gennaro Napolitano, Andrea Ballabio, Diego Di Bernardo

Duncan NRI Faculty and Staff Publications

Transcription Factor EB (TFEB) controls lysosomal biogenesis and autophagy in response to nutritional status and other stress factors. Although its regulation by nuclear translocation is known to involve a complex network of well-studied regulatory processes, the precise contribution of each of these mechanisms is unclear. Using microfluidics technology and real-time imaging coupled with mathematical modelling, we explored the dynamic regulation of TFEB under different conditions. We found that TFEB nuclear translocation upon nutrient deprivation happens in two phases: a fast one characterised by a transient boost in TFEB dephosphorylation dependent on transient calcium release mediated by mucolipin 1 (MCOLN1) followed …

Faculty, Staff and Student Publications

BACKGROUND: Scalable identification of patients with post-acute sequelae of COVID-19 (PASC) is challenging due to a lack of reproducible precision phenotyping algorithms, which has led to suboptimal accuracy, demographic biases, and underestimation of the PASC.

METHODS: In a retrospective case-control study, we developed a precision phenotyping algorithm for identifying cohorts of patients with PASC. We used longitudinal electronic health records data from over 295,000 patients from 14 hospitals and 20 community health centers in Massachusetts. The algorithm employs an attention mechanism to simultaneously exclude sequelae that prior conditions can explain and include infection-associated chronic conditions. We performed independent chart reviews …

Exploring The Mechanistic Interplay Between Chronic Inflammation And Gastrointestinal Cancer In The Gut Microbiome: A Review, Hanan Mohamed Abd Elmoneim

Saudi Toxicology Journal

There are complex and heterogeneous immunological milieus of the gastrointestinal system, so there is a high mortality rate from malignancies affecting the gastrointestinal system. The pathophysiology of cancer has long been thought to be significantly influenced by inflammation. However, several of the mechanisms underlying its tumor-promoting activities have only lately been discovered. Both beneficial and harmful microorganisms play a crucial role in controlling the host immune system and, eventually, inflammation. Furthermore, bacteria may also influence how a tumor develops through different mechanisms, including long-term inflammation activation, changes to the tumor microenvironment, and genotoxic response induction. A significant percentage of cancers …
