Effect Of Calorie Restriction On The Expression Of Sirtuin1 As An Antiaging Biomarker, Raya Makarim Penantian, Radiana Dhewayani Antarianto, Novi Silvia Hardiany

Makara Journal of Science

Calorie restriction (CR) is the most effective method for delaying aging and preventing the onset of age-related diseases. Sirtuins constitute a family of nicotinamide adenine dinucleotide (NAD)-dependent histone deacetylases. Their activity can be regulated by NAD⁺/NADH levels, which are influenced by nutrient intake, a variable acted upon by CR. This review elaborates on the link between CR and sirtuin1 (SIRT1). It retrieved articles from several sources, such as ClinicalKey, PubMed, and ScienceDirect. It discusses the up-to-date knowledge of how SIRT1 acts as a nutrient sensor and regulator of molecular mechanisms. These mechanisms include the control of the cell …

Abdel Fattah, Aydin Gülses, Tim Tjardts, Esther Afiba Kangah, Kwing Pak Gabriel Chan, Salih Salih Veziroglu, Yahya Acil, Oral Cenk Aktas, Jörg Jörg Wiltfang, Samah A. Loutfy, Thomas Strunskus, Franz Faupel, Amal Amin, Stefan Schröder

Nanotechnology Research Centre

Thin polymer coatings are used to improve the interface between biological species and functional materials. Their interaction is significantly influenced by the functional groups and roughness of the polymer film and prediction of the interaction is thus of great interest. However, for conventional polymer films, this cannot be examined independently because of the interplay of defects, residual solvent molecules, roughness, and functional groups. Solvent-free polymer films prepared by initiated chemical vapor deposition (iCVD) exhibit conformal, defect-free characteristics and enable precise tailoring of the functional groups. This facilitates to isolate the contribution of functional groups on the bio-interface performance. Consequently, in …

Dispensing With Reductionism And Dualism: Biological Anthropological Perspectives Towards Understanding Disease, Epidemics, And Pandemics, Anne Grauer

Anthropology: Faculty Publications and Other Works

At no time in recent history has the topic of disease, epidemics and pandemics been more at the forefront of public conversation than it is now. Previously, the threat of epidemics such as Ebola, the 1918 influenza epidemic, and the plague, were commonly framed as “back then” or “over there.” Perhaps COVID ended the public's delusion. For biological anthropologists, however, the perspective has differed appreciably. Pandemics and epidemics are viewed as integral and repeated aspects of human existence, and the kindling to start an outbreak of gargantuan proportion has been delicately stacked for centuries (if not millennia). If the public …

Blockade Of Interferon Signaling Decreases Gut Barrier Integrity And Promotes Severe West Nile Virus Disease, Shih-Ching Lin, Fang R Zhao, Hana Janova, Adrian Gervais, Summer Rucknagel, Kristy O Murray, Jean-Laurent Casanova, Michael S Diamond

Faculty, Staff and Students Publications

The determinants of severe disease caused by West Nile virus (WNV) and why only ~1% of individuals progress to encephalitis remain poorly understood. Here, we use human and mouse enteroids, and a mouse model of pathogenesis, to explore the capacity of WNV to directly infect gastrointestinal (GI) tract cells and contribute to disease severity. At baseline, WNV poorly infects human and mouse enteroid cultures and enterocytes in mice. However, when STAT1 or type I interferon (IFN) responses are absent, GI tract cells become infected, and this is associated with augmented GI tract and blood-brain barrier (BBB) permeability, accumulation of gut-derived …

Dopamine Signaling From Ganglion Cells Directs Layer-Specific Angiogenesis In The Retina, Justine H Liang, Viktor Akhanov, Anthony Ho, Mohamed Tawfik, Shane P D'Souza, Morven A Cameron, Richard A Lang, Melanie A Samuel

Faculty, Staff and Students Publications

During central nervous system (CNS) development, a precisely patterned vasculature emerges to support CNS function. How neurons control angiogenesis is not well understood. Here, we show that the neuromodulator dopamine restricts vascular development in the retina via temporally limited production by an unexpected neuron subset. Our genetic and pharmacological experiments demonstrate that elevating dopamine levels inhibits tip-cell sprouting and vessel growth, whereas reducing dopamine production by all retina neurons increases growth. Dopamine production by canonical dopaminergic amacrine interneurons is dispensable for these events. Instead, we found that temporally restricted dopamine production by retinal ganglion cells (RGCs) modulates vascular development. RGCs …

A Rare Cause Of Diarrhea: Intestinal Spirochetosis In An Hiv-Positive Patient., Lacey Falgout, Shilpa Kailas, Supraja Sridhar, Nisha Loganantharaj

School of Medicine Faculty Publications

Intestinal spirochetosis (IS) is a rare gastrointestinal infection with vague presenting symptoms. Diagnosis is confirmed histopathologically. Risk factors include homosexuality and HIV. Antibiotic treatment with metronidazole usually leads to resolution of symptoms. We present the case of a 56-year-old HIV-positive man with chronic, watery diarrhea who was diagnosed with IS. This case highlights the importance of considering IS in the differential in HIV-positive patients with nonspecific gastrointestinal symptoms after more common etiologies have been ruled out.

Protein S Antibody As An Adjunct Therapy For Hemophilia B, Hope P. Wilson, Aliyah Pierre, Ashley L. Paysse, Narender Kumar, Brian C. Cooley, Pratyadipta Rudra, Adrianne W. Dorsey, Diana Polania-Villanueva, Sabyasachi Chatterjee, Maissaa Janbain, Maria C. Velez, Rinku Majumder

ABSTRACT: Hemophilia B (HB) is caused by an inherited deficiency of plasma coagulation factor IX (FIX). Approximately 60% of pediatric patients with HB possess a severe form of FIX deficiency (< 1% FIX activity). Treatment typically requires replacement therapy through the administration of FIX. However, exogenous FIX has a limited functional half-life, and the natural anticoagulant protein S (PS) inhibits activated FIX (FIXa). PS ultimately limits thrombin formation, which limits plasma coagulation. This regulation of FIXa activity by PS led us to test whether inhibiting PS would extend the functional half-life of FIX and thereby prolong FIX-based HB therapy. We assayed clotting times and thrombin generation to measure the efficacy of a PS antibody for increasing FIX activity in commercially obtained plasma and plasma from pediatric patients with HB. We included 11 pediatric patients who lacked additional comorbidities and coagulopathies. In vivo, we assessed thrombus formation in HB mice in the presence of the FIXa ± PS antibody. We found an accelerated rate of clotting in the presence of PS antibody. Similarly, the peak thrombin formed was significantly greater in the presence of the PS antibody, even in plasma from patients with severe HB. Furthermore, HB mice injected with PS antibody and FIX had a 4.5-fold higher accumulation of fibrin at the thrombus induction site compared with mice injected with FIX alone. Our findings imply that a PS antibody would be a valuable adjunct to increase the effectiveness of FIX replacement therapy in pediatric patients who have mild, moderate, and severe HB.

Non-Uniform Temporal Scaling Of Developmental Processes In The Mammalian Cortex, Annalisa Paolino, Elizabeth H Haines, Evan J Bailey, Dylan A Black, Ching Moey, Fernando García-Moreno, Linda J Richards, Rodrigo Suárez, Laura R Fenlon

2020-Current year OA Pubs

The time that it takes the brain to develop is highly variable across animals. Although staging systems equate major developmental milestones between mammalian species, it remains unclear how distinct processes of cortical development scale within these timeframes. Here, we compare the timing of cortical development in two mammals of similar size but different developmental pace: eutherian mice and marsupial fat-tailed dunnarts. Our results reveal that the temporal relationship between cell birth and laminar specification aligns to equivalent stages between these species, but that migration and axon extension do not scale uniformly according to the developmental stages, and are relatively more …

Management Of Constipation In Hospitalized Patients, Gregory S Sayuk, Qi T Yu, Corey Shy

2020-Current year OA Pubs

Constipation is frequently encountered in hospital settings and can have potentially serious consequences yet is often underrecognized and undertreated. Opioid-induced constipation is a common cause of constipation in hospitalized patients. Opioids induce constipation through agonistic effects on enteric µ-opioid receptors. This review aims to provide insight on the identification and management of constipation in inpatient settings, with a particular focus on opioid-induced constipation. Constipation assessment should be routinely initiated at hospital admission and can be facilitated by thorough symptom assessments; relevant patient history, including recent medication use; physical examination; and patient assessment tools developed to evaluate the impact of constipation. …
