A globally fragmented and mobile lithosphere on Venus.

Proc Natl Acad Sci U S A 2021 Jun;118(26)

Lamont-Doherty Earth Observatory, Columbia University, Palisades, NY 10964

Venus has been thought to possess a globally continuous lithosphere, in contrast to the mosaic of mobile tectonic plates that characterizes Earth. However, the Venus surface has been extensively deformed, and convection of the underlying mantle, possibly acting in concert with a low-strength lower crust, has been suggested as a source of some surface horizontal strains. The extent of surface mobility on Venus driven by mantle convection, however, and the style and scale of its tectonic expression have been unclear. Read More

The differences of muscle proteins between neon flying squid (Ommastrephes bartramii) and jumbo squid (Dosidicus gigas) mantles via physicochemical and proteomic analyses.

Food Chem 2021 Jun 16;364:130374. Epub 2021 Jun 16.

Key Laboratory of Health Risk Factors for Seafood of Zhejiang Province, College of Food Science and Pharmacy, Zhejiang Ocean University, Zhoushan 316022, China. Electronic address:

Neon flying squid (OB) and jumbo squid (DG) mantles were evaluated to reveal the similarities and differences in their physicochemical features and protein abundances. Microstructural results indicated that the OB mantle exhibited numerous myofibril fragments and disordered microstructures after frozen storage compared with DG tissues. Chemical analysis suggested that freezing resulted in a rapid decrease in myofibrillar protein (MP) content, Ca-ATPase activity, and total sulfhydryl content, and promoted the increase in carbonyl content of MPs in both OB and DG.

Role of pH in Skin Cleansing.

Int J Cosmet Sci 2021 Jun 17. Epub 2021 Jun 17.

JL Winkle College of Pharmacy, University of Cincinnati, Cincinnati, OH, 45267, USA.

The importance of maintaining the acid-mantle of human stratum corneum to maintain its healthy barrier and skin's biological functions such as desquamation and lipid biosynthesis is well recognized in the literature. An outcome of this has been an increase in the number of skincare products formulated at or near the skin pH with an implication that a product formulated at skin pH will be good for skin. Such an assumption often does not take into account the specific interactions of ingredients in the product with the stratum corneum under skin pH conditions. Read More

Scale of plume clustering in large-Prandtl-number convection.

Phys Rev E 2021 May;103(5-1):053103

Institute of Geosciences and Earth Resources (IGG), National Research Council (CNR), Pisa 56124, Italy.

Clustering of plumes in turbulent Rayleigh-Bénard convection has been numerically observed in low-Prandtl-number fluids. In this framework, turbulent plumes undergo a phase-separation process leading to large-scale clusters and circulations, sometimes called plume superstructures and reminiscent of solar granulation and supergranulation. On the other hand, the possible presence of large-scale plume aggregates has not been explored in the case of large values of the Prandtl number, Pr, relevant to geological settings such as convection in planetary interiors.

Adjoint traveltime tomography unravels a scenario of horizontal mantle flow beneath the North China craton.

Sci Rep 2021 Jun 15;11(1):12523. Epub 2021 Jun 15.

Division of Mathematical Sciences, School of Physical and Mathematical Sciences and Asian School of the Environment, Nanyang Technological University, Singapore, Singapore.

The North China craton (NCC) was dominated by tectonic extension from late Cretaceous to Cenozoic, yet seismic studies on the relationship between crust extension and lithospheric mantle deformation are scarce. Here we present a three dimensional radially anisotropic model of NCC derived from adjoint traveltime tomography to address this issue. We find a prominent low S-wave velocity anomaly at lithospheric mantle depths beneath the Taihang Mountains, which extends eastward with a gradually decreasing amplitude. Read More

Increased complexity of t(11;14) rearrangements in plasma cell neoplasms compared with mantle cell lymphoma.

Genes Chromosomes Cancer 2021 Jun 14. Epub 2021 Jun 14.

Division of Hematopathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, Minnesota, USA.

Plasma cell neoplasms (PCN) and mantle cell lymphoma (MCL) can both harbor t(11;14)(q13;q32) (CCND1/IGH), usually resulting in cyclin D1 overexpression. In some cases, particularly at low levels of disease, it can be morphologically challenging to distinguish between these entities in the bone marrow (BM) since PCN with t(11;14) are often CD20-positive with lymphoplasmacytic cytology, while MCL can rarely have plasmacytic differentiation. We compared the difference in CCND1/IGH by fluorescence in situ hybridization (FISH) in PCN and MCL to evaluate for possible differentiating characteristics. Read More

Intrinsic 5-lipoxygenase activity regulates migration and adherence of mantle cell lymphoma cells.

Prostaglandins Other Lipid Mediat 2021 Jun 8;156:106575. Epub 2021 Jun 8.

Department of Medicine Solna, Division of Hematology, Karolinska University Hospital and Institutet, Stockholm, Sweden. Electronic address:

Human B-lymphocytes express 5-lipoxygenase (5-LOX) and 5-LOX activating protein (FLAP) and can convert arachidonic acid to leukotriene B. Mantle cell lymphoma (MCL) cells contain similar amounts of 5-LOX as human neutrophils but the function and mechanism of activation of 5-LOX in MCL cells, and in normal B-lymphocytes, are unclear. Here we show that the intrinsic 5-LOX pathway in the MCL cell line JeKo-1 has an essential role in migration and adherence of the cells, which are important pathophysiological characteristics of B-cell lymphoma.

The pathologic diagnosis of mantle cell lymphoma.

Histol Histopathol 2021 Jun 11:18351. Epub 2021 Jun 11.

Department of Hematopathology, the University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Mantle cell lymphoma (MCL) is a mature B-cell non-Hodgkin lymphoma usually characterized by t(11;14) (q13;q32), or CCND1 translocation and Cyclin D1 over expression. A very small subset of MCL may lack the t(11;14) (q13;q32) translocation and Cyclin D1 over expression, but show alternative translocations involving CCND2 and CCND3, and over expression of SOX11. In general, MCL has been considered a very aggressive and incurable lymphoma and patients with MCL usually have a poor prognosis. Read More

Crustal rejuvenation stabilised Earth's first cratons.

Nat Commun 2021 Jun 10;12(1):3535. Epub 2021 Jun 10.

Geological Survey of Western Australia, Department of Mines, Industry Regulation and Safety, East Perth, WA, Australia.

The formation of stable, evolved (silica-rich) crust was essential in constructing Earth's first cratons, the ancient nuclei of continents. Eoarchaean (4000-3600 million years ago, Ma) evolved crust occurs on most continents, yet evidence for older, Hadean evolved crust is mostly limited to rare Hadean zircons recycled into younger rocks. Resolving why the preserved volume of evolved crust increased in the Eoarchaean is key to understanding how the first cratons stabilised. Read More

Dislocation interactions in olivine control postseismic creep of the upper mantle.

Nat Commun 2021 Jun 9;12(1):3496. Epub 2021 Jun 9.

Los Alamos National Laboratory, Los Alamos, NM, USA.

Changes in stress applied to mantle rocks, such as those imposed by earthquakes, commonly induce a period of transient creep, which is often modelled based on stress transfer among slip systems due to grain interactions. However, recent experiments have demonstrated that the accumulation of stresses among dislocations is the dominant cause of strain hardening in olivine at temperatures ≤600 °C, raising the question of whether the same process contributes to transient creep at higher temperatures. Here, we demonstrate that olivine samples deformed at 25 °C or 1150-1250 °C both preserve stress heterogeneities of ~1 GPa that are imparted by dislocations and have correlation lengths of ~1 μm.

Postmelting hydrogen enrichment in the oceanic lithosphere.

Sci Adv 2021 Jun 9;7(24). Epub 2021 Jun 9.

Department of Geology and Geophysics, Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA.

The large range of HO contents recorded in minerals from exhumed mantle rocks has been challenging to interpret, as it often records a combination of melting, metasomatism, and diffusional processes in spatially isolated samples. Here, we determine the temporal variations of HO contents in pyroxenes from a 24-Ma time series of abyssal peridotites exposed along the Vema fracture zone (Atlantic Ocean). The HO contents of pyroxenes correlate with both crustal ages and pyroxene chemistry and increase toward younger and more refractory peridotites. Read More
