Sinotaia quadrata is a snail native from Asia recorded for the first time in South America in 2009 in central Argentina. In 2015, this species was also found in a lowland stream with different water qualities. Our aims were to contribute to the knowledge of its population ecology and to compare the individuals from the two locations anatomically. Snails were searched at 6 sites, where physicochemical and hydraulic parameters were measured. Biological samples were also taken at two sites (S3 and S4) to study the population traits of S...

With the introduction of next-generation sequencing, the genetic landscape of the complex group of B-cell lymphoid malignancies has rapidly been unravelled in recent years. This has provided important information about recurrent genetic events and identified key pathways deregulated in each lymphoma subtype. In parallel, there has been intense search and development of novel types of targeted therapy that 'hit' central mechanisms in lymphoma pathobiology, such as BTK, PI3K or BCL2 inhibitors. In this review, we will outline the current view of the genetic landscape of selected entities: follicular lymphoma, diffuse large B-cell lymphoma, mantle cell lymphoma, chronic lymphocytic leukaemia and marginal zone lymphoma...

An open question for solid-earth scientists is the amount of water in Earth's interior. The uppermost mantle and lower mantle contain little water because their dominant minerals, olivine and bridgmanite, have limited water storage capacity. In contrast, the mantle transition zone (MTZ) at a depth of 410 to 660 km is considered to be a potential water reservoir because its dominant minerals, wadsleyite and ringwoodite, can contain large amounts of water [up to 3 weight % (wt %)]. However, the actual amount of water in the MTZ is unknown...

Lysine-specific demethylase 1 (LSD1) has been identified and biochemically characterized in epigenetics; however, the pathological roles of its dysfunction in mantle cell lymphoma (MCL) and T-cell acute lymphoblastic leukemia remain to be elucidated. In this study, we evaluated LSD1, and histone H3 lysine 4 (H3K4)me1 and H3K4me2 expression in patients with MCL and silenced LSD1 in JeKo‑1 and MOLT‑4 cells, in order to define its role in JeKo‑1 and MOLT‑4 cell proliferation and apoptosis. We retrospectively analyzed the protein expression of LSD1, and mono- and dimethylated H3K4 (H3K4me1 and H3K4me2), and cyclin D1 and Ki67 in 30 cases of MCL by immunohistochemistry...

RHEB (Ras Homolog Enriched in Brain) is a GTP-binding protein that is ubiquitously expressed in humans and other mammals. The protein is largely involved in the mechanistic target of rapamycin (mTOR) pathway, and regulates the cell cycle progression and growth. The goal of this study was to characterize the RHEB gene in the small abalone Haliotis diversicolor, and identify the responses of RHEB gene to stresses of hypoxia or/and thermal. The objectives were to: 1) clone the full-length cDNA RHEB gene in the H...

Thioester-containing proteins (TEPs), characterized by a unique intrachain β-cysteinyl-γ-glutamyl thioester bond, form an ancient and diverse family of secreted proteins that play central roles in the innate immune response. But the existence form and immune protection mechanism of TEP in invertebrates still remain unclear, especially in the mollusks. The fragmentation and the immune-protective effect of thioester bond in CfTEP, a previously identified thioester-containing protein in scallop Chlamys farreri, were characterized in the present study...

Vertebrate cytochrome P450 1 (CYP1) enzymes metabolize endogenous and xenobiotic compounds and usually demonstrate a substrate-inducible response. Ethoxyresorufin O-deethylase activity (EROD) is a common method to quantify CYP1 enzymes activity in these organisms. Despite the absence of this gene family in protostomes, CYP1-like genes were identified in several species, even though no evolutionary relationship has been established with the vertebrate CYP1 family. In the present study, EROD activity was evaluated in microsomal fraction of gills, digestive gland and mantle of Crassostrea gigas...

CONTEXT: - Different types of mature B-cell lymphomas, including plasma cell neoplasms, exhibit distinct immunohistochemical profiles, which enable them to be correctly diagnosed. However, except for rare examples of lymphoma-specific immunohistochemistry, such as cyclin D1 in mantle cell lymphoma and annexin A1 in hairy cell leukemia, immunohistochemical profiles of mature B-cell lymphomas overlap and lack specificity. OBJECTIVES: - To systemically review immunohistochemical features associated with commonly encountered, mature B-cell lymphomas based on the presence or absence of CD5 and CD10; to review the immunophenotypic profile of plasma cells derived from plasma cell myelomas and B-cell lymphomas; and to review a group of rare, aggressive B-cell lymphomas with antigen expression features of plasma cells...

The pearl oyster Pinctada maxima exhibits great difficulty to culture pearls through nuclear insertion with an allograft, but it is easy for P. fucata to culture pearls after allografting. If P. fucata could be used as a surrogate mother to culture P. maxima pearls, it would benefit the pearl culture industry of P. maxima. However, this is blocked by the immune rejection of P. fucata against P. maxima mantle grafts. In this study, the immune responses of P. fucata hemocyte to allograft and xenograft were investigated after transplantation by transcriptome analysis...

The common cuttlefish (Sepia officinalis), a dominant species in the north-east Atlantic ocean and Mediterranean Sea, is potentially subject to hypoxic conditions due to eutrophication of coastal waters and intensive aquaculture. Here we initiate studies on the biochemical response to an anticipated level of hypoxia. Cuttlefish challenged for 1 h at an oxygen level of 50% dissolved oxygen saturation showed a decrease in oxygen consumption of 37% associated with an 85% increase in ventilation rate. Octopine levels were increased to a small but significant level in mantle, whereas there was no change in gill or heart...

Hormones have a key role in energy allocation, so their study allows understanding individual metabolic strategies. Because different hormones convey different information on the responses of individuals to energetic demands, a simultaneous analysis of variation in multiple hormones may offer a more reliable picture of metabolic strategies than single hormone assessments. In this study we focused on determining which factors were related to variation in fecal glucocorticoid and thyroid hormone metabolites in wild mantled howler monkeys (Alouatta palliata)...

Water plays an important role in geological processes. Providing constraints on what may influence the distribution of aqueous fluids is thus crucial to understanding how water impacts Earth's geodynamics. Here we demonstrate that ductile flow exerts a dynamic control on water-rich fluid circulation in mantle shear zones. Based on amphibole distribution and using dislocation slip-systems as a proxy for syn-tectonic water content in olivine, we highlight fluid accumulation around fine-grained layers dominated by grain-size-sensitive creep...
