Microbiome-Targeting Therapies In The Neonatal Intensive Care Unit: Safety And Efficacy, Anna Deveaux, Jian Ryou, Gautam Dantas, Barbara B Warner, Phillip I Tarr

2020-Current year OA Pubs

Microbiome-targeting therapies have received great attention as approaches to prevent disease in infants born preterm, but their safety and efficacy remain uncertain. Here we summarize the existing literature, focusing on recent meta-analyses and systematic reviews that evaluate the performance of probiotics, prebiotics, and/or synbiotics in clinical trials and studies, emphasizing interventions for which the primary or secondary outcomes were prevention of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and/or reduction in hospitalization length or all-cause mortality. Current evidence suggests that probiotics and prebiotics are largely safe but conclusions regarding their effectiveness in the neonatal intensive care unit have been mixed. To …

Structural And Biophysical Characterization Of The Secreted, Β-Helical Adhesin Etpa Of Enterotoxigenic Escherichia Coli, Clifford Manyo Ntui, James M. Fleckenstein, Wolf-Dieter Schubert

2020-Current year OA Pubs

Enterotoxigenic Escherichia coli (ETEC) is a diarrhoeal pathogen associated with high morbidity and mortality especially among young children in developing countries. At present, there is no vaccine for ETEC. One candidate vaccine antigen, EtpA, is a conserved secreted adhesin that binds to the tips of flagellae to bridge ETEC to host intestinal glycans. EtpA is exported through a Gram-negative, two-partner secretion system (TPSS, type Vb) comprised of the secreted EtpA passenger (TpsA) protein and EtpB (TpsB) transporter that is integrated into the outer bacterial membrane. TpsA proteins share a conserved, N-terminal TPS domain followed by an extensive C-terminal domain with …

Unicorn, Hare, Or Tortoise? Using Machine Learning To Predict Working Memory Training Performance, Yi Feng, Anja Pahor, Aaron R Seitz, Dennis L Barbour, Susanne M Jaeggi

2020-Current year OA Pubs

People differ considerably in the extent to which they benefit from working memory (WM) training. Although there is increasing research focusing on individual differences associated with WM training outcomes, we still lack an understanding of which specific individual differences, and in what combination, contribute to inter-individual variations in training trajectories. In the current study, 568 undergraduates completed one of several N-back intervention variants over the course of two weeks. Participants' training trajectories were clustered into three distinct training patterns (high performers, intermediate performers, and low performers). We applied machine-learning algorithms to train a binary tree model to predict individuals' training …

2020-Current year OA Pubs

PURPOSE: Stunting is known to be heavily influenced by environmental factors, so the genetic contribution has received little attention. Here we report an exploration of genetic influences in stunted Zambian children with environmental enteropathy.

METHOD: Children with stunting (LAZ < -2) were enrolled and given nutritional therapy. Those that were non-responsive to therapy were designated as cases, and children with good growth (LAZ > -1) from the same community as controls. Blood and stool samples were taken to measure biomarkers of intestinal inflammation, epithelial damage, and microbial translocation. Single nucleotide polymorphism array genotyping was carried out on saliva samples using the H3Africa consortium array.

RESULTS: Genome wide associations were analysed in 117 cases and 41 controls. While no significant associations with stunting were observed at …

2020-Current year OA Pubs

Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by cognitive decline and atrophy in the medial temporal lobe (MTL) and subsequent brain regions. Structural magnetic resonance imaging (sMRI) has been widely used in research and clinical care for diagnosis and monitoring AD progression. However, atrophy patterns are complex and vary by patient. To address this issue, researchers have made efforts to develop more concise metrics that can summarize AD-specific atrophy. Many of these methods can be difficult to interpret clinically, hampering adoption. In this study, we introduce a novel index which we call an "AD-NeuroScore," that uses a modified …

Two adaptation sessions were performed in which the GTV was recontoured, first at …

Elevated Liver Glycogenolysis Mediates Higher Blood Glucose During Acute Exercise In Barth Syndrome, George G. Schweitzer, Grace L. Ditzenberger, Curtis C. Hughey, Brian N. Finck, Michael R. Martino, Christina A. Pacak, Barry J. Byrne, William Todd Cade

2020-Current year OA Pubs

UNLABELLED: Barth syndrome (BTHS) is an X-linked recessive genetic disorder due to mutations in the Tafazzin (TAFAZZIN) gene that lead to cardiac and skeletal muscle mitochondrial dysfunction. Previous studies in humans with BTHS demonstrate that the defects in muscle mitochondrial oxidative metabolism result in an enhanced reliance on anaerobic metabolism during exercise to meet energy demands of muscular work. During exercise, the liver normally increases glucose production via glycogenolysis and gluconeogenesis to match the elevated rate of muscle glucose uptake and meet the ATP requirements of working muscle. However, the impact of Tafazzin deficiency on hepatic glucose production and the …

Evolution And Implementation Of Radiographic Response Criteria In Neuro-Oncology, Divya Ramakrishnan, Marc Von Reppert, Mark Krycia, Matthew Sala, Sabine Mueller, Sanjay Aneja, Ali Nabavizadeh, Norbert Galldiks, Philipp Lohmann, Cyrus Raji, Ichiro Ikuta, Fatima Memon, Brent D Weinberg, Mariam S Aboian

2020-Current year OA Pubs

Radiographic response assessment in neuro-oncology is critical in clinical practice and trials. Conventional criteria, such as the MacDonald and response assessment in neuro-oncology (RANO) criteria, rely on bidimensional (2D) measurements of a single tumor cross-section. Although RANO criteria are established for response assessment in clinical trials, there is a critical need to address the complexity of brain tumor treatment response with multiple new approaches being proposed. These include volumetric analysis of tumor compartments, structured MRI reporting systems like the Brain Tumor Reporting and Data System, and standardized approaches to advanced imaging techniques to distinguish tumor response from treatment effects. In …

Genetics Of Vegetarianism: A Genome-Wide Association Study, Nabeel R. Yaseen, Catriona L. K. Barnes, Lingwei Sun, Akiko Takeda, John P. Rice

2020-Current year OA Pubs

A substantial body of evidence points to the heritability of dietary preferences. While vegetarianism has been practiced for millennia in various societies, its practitioners remain a small minority of people worldwide, and the role of genetics in choosing a vegetarian diet is not well understood. Dietary choices involve an interplay between the physiologic effects of dietary items, their metabolism, and taste perception, all of which are strongly influenced by genetics. In this study, we used a genome-wide association study (GWAS) to identify loci associated with strict vegetarianism in UK Biobank participants. Comparing 5,324 strict vegetarians to 329,455 controls, we identified …

Sting Suppresses Mitochondrial Vdac2 To Govern Rcc Growth Independent Of Innate Immunity, Zhichuan Zhu, Xin Zhou, Hongwei Du, Erica W Cloer, Jiaming Zhang, Liu Mei, Ying Wang, Xianming Tan, Austin J Hepperla, Jeremy M Simon, Jeanette Gowen Cook, Michael B Major, Gianpietro Dotti, Pengda Liu

2020-Current year OA Pubs

STING is an innate immune sensor for immune surveillance of viral/bacterial infection and maintenance of an immune-friendly microenvironment to prevent tumorigenesis. However, if and how STING exerts innate immunity-independent function remains elusive. Here, the authors report that STING expression is increased in renal cell carcinoma (RCC) patients and governs tumor growth through non-canonical innate immune signaling involving mitochondrial ROS maintenance and calcium homeostasis. Mitochondrial voltage-dependent anion channel VDAC2 is identified as a new STING binding partner. STING depletion potentiates VDAC2/GRP75-mediated MERC (mitochondria-ER contact) formation to increase mitochondrial ROS/calcium levels, impairs mitochondria function, and suppresses mTORC1/S6K signaling leading to RCC growth …

Updates In The Chronic Kidney Disease-Mineral Bone Disorder Show The Role Of Osteocytic Proteins, A Potential Mechanism Of The Bone-Vascular Paradox, A Therapeutic Target, And A Biomarker, Matthew J Williams, Sarah C White, Zachary Joseph, Keith A Hruska

2020-Current year OA Pubs

The chronic kidney disease-mineral bone disorder (CKD-MBD) is a complex multi-component syndrome occurring during kidney disease and its progression. Here, we update progress in the components of the syndrome, and synthesize recent investigations, which suggest a potential mechanism of the bone-vascular paradox. The discovery that calcified arteries in chronic kidney disease inhibit bone remodeling lead to the identification of factors produced by the vasculature that inhibit the skeleton, thus providing a potential explanation for the bone-vascular paradox. Among the factors produced by calcifying arteries, sclerostin secretion is especially enlightening. Sclerostin is a potent inhibitor of bone remodeling and an osteocyte …

From Perception To Behavior: The Neural Circuits Underlying Prey Hunting In Larval Zebrafish, Shuyu I Zhu, Geoffrey J Goodhill

2020-Current year OA Pubs

A key challenge for neural systems is to extract relevant information from the environment and make appropriate behavioral responses. The larval zebrafish offers an exciting opportunity for studying these sensing processes and sensory-motor transformations. Prey hunting is an instinctual behavior of zebrafish that requires the brain to extract and combine different attributes of the sensory input and form appropriate motor outputs. Due to its small size and transparency the larval zebrafish brain allows optical recording of whole-brain activity to reveal the neural mechanisms involved in prey hunting and capture. In this review we discuss how the larval zebrafish brain processes …

Necrotic Cardiac Myocytes Skew Macrophage Polarization Towards A Classically Activated Phenotype, Wenlong Jiang, Luigi Adamo, Kenji Lim, Scot J Matkovich, Sarah Evans, Cibele Rocha-Resende, Douglas L. Mann

2020-Current year OA Pubs

Necrotic and dying cells release damage-associated molecular patterns (DAMPs) that can initiate sterile inflammatory responses in the heart. Although macrophages are essential for myocardial repair and regeneration, the effect of DAMPs on macrophage activation remains unclear. To address this gap in knowledge we studied the effect of necrotic cardiac myocyte extracts on primary peritoneal macrophage (PPM) cultures in vitro. We first performed unbiased transcriptomic profiling with RNA-sequencing of PPMs cultured for up to 72 hours in the presence and absence of: 1) necrotic cell extracts (NCEs) from necrotic cardiac myocytes in order to mimic the release of DAMPs; 2) lipopolysaccharide …
