Shewanella psychromarinicola sp. nov., a psychrophilic bacterium isolated from pelagic sediment of the Ross Sea (Antarctica), and reclassification of Shewanella arctica Kim et al. 2012 as a later heterotypic synonym of Shewanella frigidimarina Bowman et al. 1997.
Abstract Two Gram-stain-negative, rod-shaped, facultatively anaerobic, iron-reducing bacterial strains, designated M2T and R106, were isolated from pelagic surface-sediment of the Ross Sea, Antarctica. The 16S rRNA gene sequence analysis revealed that strains M2T and R106 were affiliated to the genus Shewanellaand formed a distinct subline in a robust clade encompassing Shewanella vesiculosa, Shewanella livingstonensis, Shewanella arcticaand Shewanella frigidimarinawith a range of sequence similarities of 98.1-98.9 %. Overall genome relatedness indices indicated that M2T and R106 represented a single genomic s...

CRISPR Gene Editing Is Being Tested in Human Patients, and the Results Could Revolutionize Health Care
It’s only been seven years since scientists first learned how to precisely and reliably splice the human genome using a tool called CRISPR, making it possible to think about snipping out disease-causing mutations and actually cure, once and for all, genetic diseases ranging from sickle cell anemia to certain types of cancer and even blindness. Doctors are plunging ahead in search of ways to use the relatively new technology to start treating patients. In China last November, scientist Jiankui He stunned—and dismayed—the genetic community when he announced he had already used CRISPR, which many believe sti...

Identification and functional characterization of natural resistance-associated macrophage protein 2 from sea cucumber Apostichopus japonicus.
In this study, a unique echinoderm Nramp2 was identified from sea cucumber Apostichopus japonicus (designated as AjNramp2). The cDNA sequence of AjNramp2 was 2360 bp, with a putative open reading frame of 1713 bp, encoding a typical Nramp domain containing protein with 570 amino acid residues. Structural analysis revealed that AjNramp2 consisted of highly conserved helix regions similar with the human Nramp2. Spatial expression analysis revealed that AjNramp2 was ubiquitously expressed in all examined tissues, with the highest level found in the intestine. Immunohistochemistry assay showed that AjNramp2 was mainly located ...

Microplastics as vectors of metals contamination in Mediterranean Sea
Environ Sci Pollut Res Int. 2021 Mar 30. doi: 10.1007/s11356-021-13662-7. Online ahead of print.ABSTRACTMicroplastics are contaminants of great concern all over the world. Microplastics constitute pollutants themselves; moreover, other contaminants such as metals are easily absorbed on their plastic surface, becoming bioavailable to marine biota such as zooplankton.We collected marine zooplankton from Mediterranean Sea to investigate trace elements associated with microplastics. Samples were subjected to visual sorting by a stereomicroscope, collected with sterile tweezers, pooled and subjected to sonication, filtration, a...

Off-label tocilizumab and adjuvant iron chelator effectiveness in a group of severe COVID-19 pneumonia patients: A single center experience
Tocilizumab (TCZ), a monoclonal recombinant antibody against IL-6 receptor, is currently used in managing the cytokine release syndrome (CRS) that occurred in coronavirus disease 2019 (COVID-19) selected cases. The primary objective of our study was to establish the effectiveness of TCZ in patients with severe or critical severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pneumonia. We retrospectively analyzed 25 consecutive patients, admitted in the Academic Emergency Hospital Sibiu, Romania from April 1, 2020 until May 25, 2020, all with confirmed SARS-CoV-2 infection and severe pneumonia. All patients were ...

Molecular and functional characterization of a SCD 1b from European sea bass (Dicentrarchus labrax L.)
Comp Biochem Physiol B Biochem Mol Biol. 2021 Nov 18:110698. doi: 10.1016/j.cbpb.2021.110698. Online ahead of print.ABSTRACTFatty acid desaturation is a highly complex and regulated process involving different molecular and genetic actors. Ultimally, the fatty acid desaturase enzymes are responsible for the introduction of double bonds at different positions of specific substrates, resulting in a wide variety of mono- and poly-unsaturated fatty acids. This substrate-specificity makes it possible to meet all the functional needs of the different tissues against a wide variety of internal and external conditions, giving rise...

Metals in Ten Commercial Demersal Fish from the East China Sea: Contribution to Aquatic Products Nutrition and Toxic Risk Assessment
Biol Trace Elem Res. 2022 Jan 7. doi: 10.1007/s12011-021-03087-1. Online ahead of print.ABSTRACTMetal accumulation in the marine environment can increase the metal content of fish living in it. For this reason, it is essential to evaluate the nutrition from fish consumption and assess metal toxicity risk. Ten species of demersal fish, which are part of the daily diet of coastal residents, were sampled using trammel net in the East China Sea. Levels of the microelements, the constant elements, and the toxic elements of muscle tissue were analyzed. Spiny red gurnard had the highest concentrations of calcium, copper, and iron...
