Echinochrome A Release by Red Spherule Cells Is an Iron-Withholding Strategy of Sea Urchin Innate Immunity
Cellular immune defences in sea urchins are shared amongst the coelomocytes - a heterogeneous population of cells residing in the coelomic fluid (blood equivalent) and tissues. The most iconic coelomocyte morphotype is the red spherule cell (or amebocyte), so named due to the abundance of cytoplasmic vesicles containing the naphthoquinone pigment echinochrome A. Despite their identification over a century ago, and evidence of antiseptic properties, little progress has been made in characterising the immunocompetence of these cells. Upon exposure of red spherule cells from sea urchins, i.e.,Paracentrotus lividusand Psammech...

Benthic cycling of phosphorus in the Eastern Arabian Sea: Evidence of present day phosphogenesis
Publication date: 20 February 2018 Source:Marine Chemistry, Volume 199 Author(s): P. Linsy, B. Nagender Nath, M.B.L. Mascarenhas-Pereira, P.V. Vinitha, Durbar Ray, C. Prakash Babu, B. Ramalingeswara Rao, Armoury Kazip, Tyson Sebastian, Murlidhar Kocherla, Pavan Miriyala Results of a study on phosphorus (P) cycling in the Eastern Arabian Sea provides convincing evidence of present-day phosphogenesis in the study area. This finding contrasts with previous reports of the occurrence of only old phosphorites along the Indian margin. Extensive benthic P regeneration is observed in the sediments that are deposited on topographic...

Specific enrichment of hyperthermophilic electroactive Archaea from deep-sea hydrothermal vent on electrically conductive support.
Abstract While more and more investigations are done to study hyperthermophilic exoelectrogenic communities from environments, none have been performed yet on deep-sea hydrothermal vent. Samples of black smoker chimney from Rainbow site on the Atlantic mid-oceanic ridge have been harvested for enriching exoelectrogens in microbial electrolysis cells under hyperthermophilic (80 °C) condition. Two enrichments were performed in a BioElectrochemical System specially designed: one from direct inoculation of crushed chimney and the other one from inoculation of a pre-cultivation on iron (III) oxide. In both experimen...

Obsessive Measurement Disorder: Etiology of an Epidemic
By KIP SULLIVAN JD  Review of The Tyranny of Metrics by Jerry Z. Muller, Princeton University Press, 2018 In the introduction to The Tyranny of Metrics, Jerry Muller urges readers to type “metrics” into Google’s Ngram, a program that searches through books and other material published over the last five centuries. He tells us we will find that the use of “metrics” soared after approximately 1985. I followed his instructions and confirmed his conclusion (see graph below). We see the same pattern for two other buzzwords that activate Muller’s BS antennae – “benchmarks,” and “performance indicators.” ...

Facile Preparation of Antifouling Hydrogel Architectures for Drag Reduction and Oil/Sea Water Separation
Publication date: Available online 23 August 2019Source: Materials Today CommunicationsAuthor(s): Zitong Wang, Shuanhong Ma, Haiquan Zhong, Wufang Yang, Xiaowei Pei, Bo Yu, Kai Su, Feng ZhouAbstractMaterials and technologies which can resist the adhesion of microorganisms, purify the wastewater and transport fluid with lower drag have been explored avidly, but a number of challenges still remain. A hydrogel coating anchored on the structured surface was fabricated through a facile surface self-catalyzed polymerization in situ. The necessary physicochemical properties of as-prepared hydrogel substrate were characterized, an...

Restless Legs Syndrome in Chronic Kidney Disease: Is Iron or Inflammatory Status To Blame?
Conclusions:Neither ferritin nor inflammation differentiated pediatric patients with CKD with and without RLS. This study suggests that the factors mediating the pathogenesis and, potentially, treatment, of RLS in pediatric CKD may be different from non-CKD populations.Citation:Riar SK, Greenbaum LA, Bliwise DL, Leu RM. Restless legs syndrome in chronic kidney disease: is iron or inflammatory status to blame?J Clin Sleep Med. 2019;15(11):1629–1634.

A survey of primary-care pediatricians regarding the management of Helicobacter pylori infection and celiac disease
ConclusionsAdherence to the guidelines on management ofH. pylori infection was low, while adherence to the guidelines on celiac disease management was high among primary-care pediatricians. Educational interventions are needed to improveH. pylori infection management among primary-care pediatricians.

Effectiveness of Deferasirox in Pediatric Thalassemia Patients: Experience from a Tertiary Care Hospital of Odisha
CONCLUSIONS: Deferasirox is an effective iron chelator when started at an optimum time and with optimum dose. At least 1 year of deferasirox therapy is needed for a significant lowering of serum ferritin levels of pediatric thalassemia patients on multiple blood transfusions.

Circulating trace elements: comparison between early and late incubation in common eiders (Somateria mollissima) in the central Baltic Sea.
Abstract We analyzed body mass and a panel of 64 trace elements in blood from incubating common eiders (Somateria mollissima) in the central Baltic Sea during the breeding seasons of 2017 (n = 27) and 2018 (n = 23). Using a non-invasive approach, the same incubating eiders nesting on Christiansø, Denmark were sampled once on day 4 and day 24 of incubation to provide a comparison between the early and late stages of incubation. Blood concentrations of chemical elements were quantified using high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Cadmium and lead significantly increased over the c...

Iron transport across the human placenta is regulated by hepcidin.
CONCLUSIONS: Our data suggest that hepcidin plays an important role in the regulation of iron transport across the placenta, making it a critical link in movement of iron into fetal circulation. IMPACT: Hepcidin has a direct impact on iron transport across the human placenta.This study provides the first evidence of direct regulation of iron efflux from human trophoblast cells by hepcidin.These data extend our understanding of iron transport across the maternal-fetal interface, a process critical for fetal health and development.

Enrichment of novel Verrucomicrobia, Bacteroidetes, and Krumholzibacteria in an oxygen ‐limited methane‐ and iron‐fed bioreactor inoculated with Bothnian Sea sediments
In this study, we inoculated a bioreactor with methane ‐ and iron‐rich sediments from the Bothnian Sea to investigate microbial methane and iron cycling under low oxygen concentrations. Using metagenomics, we investigated shifts in microbial community composition after approximately 2.5 years of bioreactor operation. Marker genes for methane and ir on cycling, as well as respiratory and fermentative metabolism, were identified and used to infer putative microbial metabolism. Metagenome‐assembled genomes representing novelVerrucomicrobia,Bacteroidetes, andKrumholzibacteria were recovered and revealed a potential for ...

Ceratothoa oestroides Infection in European Sea Bass: Revealing a Long Misunderstood Relationship
Ceratothoa oestroides (Cymothoidea, Isopoda) is a generalist crustacean parasite that negatively affects the economic sustainability of European sea bass (Dicentrarchus labrax) aquaculture in the North-East Mediterranean. While mortalities are observed in fry and fingerlings, infection in juvenile and adult fish result in approximately 20% growth delay. A transcriptomic analysis (PCR array, RNA-Seq) was performed on organs (tongue, spleen, head kidney, and liver) from infected vs. Ceratothoa-free sea bass fingerlings. Activation of local and systemic immune responses was detected, particularly in the spleen, characterized ...
