Influence of glacial water and carbonate minerals on wintertime sea-ice biogeochemistry and the CO2 system in an Arctic fjord in Svalbard

open access: yesAnnals of Glaciology, 2020
The effect of freshwater sources on wintertime sea-ice CO2 processes was studied from the glacier front to the outer Tempelfjorden, Svalbard, in sea ice, glacier ice, brine and snow.

Glacial erosion and bedrock properties in NW Scotland : abrasion and plucking, hardness and joint spacing [PDF]

open access: yes, 2011
Subglacial erosion beneath glaciers occurs predominantly by abrasion and plucking, producing distinct erosional forms. The controls on the relative importance of abrasion vs. plucking are poorly understood.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Morfometric characteristics, pedology and land use with special consideration on viticulture and fruit growing in the Slovenske gorice region between the Mura and Pesnica rivers

open access: yesRevija za Geografijo, 2017
When mentioning The Slovenske gorice region an average Slovene resident thinks of hills with vineyards and orchards. However, the appearance of this region between the Mura and Pesnica Rivers has changed.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

THE EXPERIMENTAL STUDY ON THE BEDROCK EXPOSER EXPANSION UNDER THIN ALLUVIAL COVER THICKNESS CONDITION [PDF]

open access: yes, 2017
過去に著者らが確認した覆礫厚が薄く(砂州波高の半分の厚さ),固定床が平滑な条件での露岩部の伸長現象をより詳細に把握するため,水理実験を行った.通水時間を著者らによる既往研究よりも長くしたケースでは,著者らによる既往研究と同様に,水路中・上流側で砂州前縁部の露岩部が伸長し,下流側においては短縮することを確認した.さらにその後の通水では,水路上流端で新たに発生した砂州の前縁部の露岩部が伸長し,直下流部の伸長していた露岩部(砂州)が短縮した.このことから,覆礫厚が薄く,固定床上が平滑な条件での露岩部(砂州 ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
