Antibiotic-Induced Gut Dysbiosis And Cognitive, Emotional, And Behavioral Changes In Rodents: A Systematic Review And Meta-Analysis, Shivdeep S. Hayer, Soonjo Hwang, Jonathan B. Clayton

Food for Health: Publications

There are previous epidemiological studies reporting associations between antibiotic use and psychiatric symptoms. Antibiotic-induced gut dysbiosis and alteration of microbiota-gut-brain axis communication has been proposed to play a role in this association. In this systematic review and meta-analysis, we reviewed published articles that have presented results on changes in cognition, emotion, and behavior in rodents (rats and mice) after antibiotic-induced gut dysbiosis. We searched three databases—PubMed, Web of Science, and SCOPUS to identify such articles using dedicated search strings and extracted data from 48 articles. Increase in anxiety and depression-like behavior was reported in 32.7 and 40.7 percent of the …

Homeobox Transcription Factor Hbxa Influences Expression Of Over One Thousand Genes In The Model Fungus Aspergillus Nidulans, Sandesh S. Pandit, Jinfang Zheng, Yanbin Yan, Sophie Lorber, Olivier Puel, Sourabh Dhingra, Eduardo A. Espeso, Ana M. Calvo

Food for Health: Publications

In fungi, conserved homeobox-domain proteins are transcriptional regulators governing development. In Aspergillus species, several homeobox-domain transcription factor genes have been identified, among them, hbxA/hbx1. For instance, in the opportunistic human pathogen Aspergillus fumigatus, hbxA is involved in conidial production and germination, as well as virulence and secondary metabolism, including production of fumigaclavines, fumiquinazolines, and chaetominine. In the agriculturally important fungus Aspergillus flavus, disruption of hbx1 results in fluffy aconidial colonies unable to produce sclerotia. hbx1 also regulates production of aflatoxins, cyclopiazonic acid and aflatrem. Furthermore, transcriptome studies revealed that hbx1 has a broad effect on …

We read with interest the study by Kayisoglu et al¹ comparing the gene expression between embryo-derived and adult-derived intestinal organoids. Some innate immune system genes were differentially expressed between the two organoid types, suggesting a potential role of exposure to the environment, including gut microbiota, in shaping the intestinal gene expression. In extremely preterm infants (<32 weeks gestation), microbial–host interaction at the epithelial surface has been associated with various morbidities including late onset sepsis and necrotising enterocolitis.² Thus, preterm intestinal organoids may provide a specific and robust model for this population.

The Inherited Intestinal Microbiota From Myeloid-Specific Zip8ko Mice Impairs Pulmonary Host Defense Against Pneumococcal Pneumonia, Derrick R. Samuelson, Deandra R. Smith, Kelly C. Cunningham, Sabah Haq, Daniel N. Villageliú, Christi Christi Ellis, Niaz Bahar Chowdhury, Amanda E. Ramer-Tait, Jeff Price, Daren L. Knoell

Intestinal dysbiosis increases susceptibility to infection through the alteration of metabolic profiles, which increases morbidity. Zinc (Zn) homeostasis in mammals is tightly regulated by 24 Zn transporters. ZIP8 is unique in that it is required by myeloid cells to maintain proper host defense against bacterial pneumonia. In addition, a frequently occurring ZIP8 defective variant (SLC39A8 rs13107325) is strongly associated with inflammation-based disorders and bacterial infection. In this study, we developed a novel model to study the effects of ZIP8-mediated intestinal dysbiosis on pulmonary host defense independent of the genetic effects. Cecal microbial communities from a myeloid-specific Zip8 knockout mouse …

Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry

Senior Honors Theses

Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …

Longitudinal associations between dietary fructose and sodium and systolic and diastolic blood pressure among US Black and White adults in the CARDIA study

Authors: Rana Elhamzawy, Daniel Domin, Dragana Komnenov

Hypertension is one of the leading risk factors for major adverse cardiovascular events (MACE). Likewise, suboptimal dietary habits, including high fructose and sodium intake, are major contributors to mortality. High dietary fructose alone predisposes to salt-sensitivity of blood pressure, which is an independent, significant cardiovascular risk factor. We previously showed in our rat model of fructose-salt-sensitive hypertension that even a short term (4 weeks) feeding with 20% fructose and 4% …

Influence Of Aerobic Exercise On Appetite-Regulating Hormones, Ghrelin-O-Acyltransferase And Perceived Hunger In Normal Weight And Obese Adults, Michael Bruneau, Richard Wood, Susan Sotir, Samuel Headley, Elizabeth O'Neil, Juan Muñiz, May Cheung, Marissa Pontarelli

Department of Medical Oncology Faculty Papers

Background: Obesity is a major public health issue in the United States (U.S.), affecting an estimated 78 million US adults. Aerobic exercise (AE) is recommended by the American College of Sports Medicine to prevent and treat obesity, yet the effects of AE on circulating hunger hormones including acylated ghrelin and its biological catalyst, ghrelin o-acyltransferase (GOAT) are less known. Objectives: We investigated the effects of AE on circulating concentrations of appetite regulating hormones and GOAT in a pilot sample of adults classified with normal weight (NW) and obese (OB) body weight status. Methods: Using a quasi-experimental design, nine adults with …

Radiology departments have contributed significantly to greenhouse gases including release of toxic imaging contrast media to environment. We feel Radiology also has several spectroscopy and imaging tools that may apply to monitor and support cleaner environmental goals. The current manuscript is one of the firsts to prompt Radiology to move in that direction by non invasive imaging of bio metals that are less abundant in biological tissues but play key roles as co-factors in tissue structure and function. Conventional analytical tools are mostly invasive and cannot characterize the native oxidation states of bio metals. We chose carbohydrate matrix of metal-rich …
