A coccoid-shaped, strictly anaerobic, hyperthermophilic and piezophilic organoheterotrophic archaeon, strain Iri35cT, was isolated from a hydrothermal chimney rock sample collected at a depth of 2300 m at the Mid-Atlantic Ridge (Rainbow vent field). Cells of strain Iri35cT grew at NaCl concentrations ranging from 1-5 % (w/v) (optimum 2.0 %), from pH 5.0 to 9.0 (optimum 7.0-7.5), at temperatures between 50 and 90 °C (optimum 75-80 °C) and at pressures from 0.1 to at least 50 MPa (optimum 10-30 MPa). The novel isolate grew on complex organic substrates, such as yeast extract, tryptone, peptone or beef extract, preferentially in the presence of elemental sulphur or l-cystine; however, these molecules were not necessary for growth. Its genomic DNA G+C content was 54.63 mol%. The genome has been annotated and the metabolic predictions are in accordance with the metabolic characteristics of the strain and of Thermococcales in general. Phylogenetic analyses based on 16S rRNA gene sequences and concatenated ribosomal protein sequences showed that strain Iri35cT belongs to the genus Thermococcus, and is closer to the species T. celericrescens and T. siculi. selleck compound Average nucleotide identity scores and in silico DNA-DNA hybridization values between the genome of strain Iri35cT and the genomes of the type species of the genus Thermococcus were below the species delineation threshold. Therefore, and considering the phenotypic data presented, strain Iri35cT is suggested to represent a novel species, for which the name Thermococcus camini sp. nov. is proposed, with the type strain Iri35cT (=UBOCC M-2026T=DSM 111003T).We characterized the morphological and anatomical adaptations of the lingual microstructures of the Eurasian collared dove and discussed their implications for its dietary niche. We analyzed tongues of nine S. decaocto using histological, histochemical, stereomicroscopic, and scanning electron microscopic techniques. Our findings showed that the tongue is relatively short with a tapered apex that carries a terminal lingual nail. However, the lingual body has median scales and is bordered laterally by filiform papillae. Further, the tongue body bears a distinctive papillary crest. The tongue root is nonpapillate and infiltered with orifices of the posterior salivary glands. The bulky laryngeal mound has a circular glottic fissure, carrying a single row of papillae at the rear edge. Concurrently, our histological and histochemical findings demonstrate that the tongue has taste buds, anterior and posterior salivary glands, along with an elongated entoglossum that extends from lingual apex to root. Besides, ovoid and globular mucous glands displayed intense alcianophilic reactions. More substantially, the palate is made up of three palatine ridges with a caudal choanal cleft that was bounded by two rows of palatine papillae. Our data indicate multiple and novel structural variations for the lingual and palatal sculptures coopted for their feeding style.The FDA-approved proteasomal inhibitor bortezomib (BTZ) has attracted interest for its potential anti-fibrotic actions. However, neither its in vivo efficacy in lung fibrosis nor its dependence on proteasome inhibition has been conclusively defined. In this study, we assessed the therapeutic efficacy of BTZ in a mouse model of pulmonary fibrosis, developed an in vitro protocol to define its actions on diverse fibroblast activation parameters, determined its reliance on proteasome inhibition for these actions in vivo and in vitro and explored alternative mechanisms of action. The therapeutic administration of BTZ diminished the severity of pulmonary fibrosis without reducing proteasome activity in the lung. In experiments designed to mimic this lack of proteasome inhibition in vitro, BTZ reduced fibroblast proliferation, differentiation into myofibroblasts, and collagen synthesis. It promoted de-differentiation of myofibroblasts and overcame their characteristic resistance to apoptosis. Mechanistically, BTZ inhibited kinases important for fibroblast activation while inducing expression of dual-specificity phosphatase 1 or DUSP1, and knockdown of DUSP1 abolished its anti-fibrotic actions in fibroblasts. Collectively, these findings suggest that BTZ exhibits a multidimensional profile of robust inhibitory actions on lung fibroblasts as well as anti-fibrotic actions in vivo. Unexpectedly, these actions appear to be independent of proteasome inhibition, and instead attributable to induction of DUSP1.This study examined the factors associated with acceptance of the COVID-19 vaccine compared to hesitance in the Pakistani population and specifically focusing on the perceived beliefs, knowledge, concerns, risk, and safety perception relating to the COVID-19 vaccine. A total of 423 subjects were recruited from the Pakistan Institute of Medical Sciences, Islamabad, Pakistan. A 27-item valid and reliable questionnaire was used to assess socio-demographic characteristics, acceptance, and hesitance toward COVID-19 vaccine, perceived beliefs, knowledge, perceived concerns, risk, and safety of COVID-19 vaccines and its source of information. Chi-square tests and logistic regression were used for analysis. About 53% of the participants were planning to get vaccinated and a significantly greater proportion of better educated, higher income, and healthier participants in the vaccine acceptance group (p less then .05). The odds of knowing the vaccine they should get, having the confidence in the vaccine to stop the pandemic, and understanding the way vaccines work, were greater in the vaccine acceptance group than the vaccine-hesitant group (OR 5.4; 3.5, 2.1, 3.1, respectively). Most participants (52.3%) obtained the information regarding the COVID-19 vaccine from the print and live news media (52.3%) followed by social media (23.7%). The lack of knowledge, understanding, and perception of the risk, safety partly explains the low rate of vaccine acceptance in the Pakistani population. Strategies to raise awareness of the benefits of vaccination should target individuals in the lower socioeconomic group and those with chronic disease.
