FEBS 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 ...

Electrochemical Corrosion Behavior of Chromium-Free Composite Passivation Film on Galvanized Steel
International Journal of Electrochemical Science, 2018 An eco-friendly and economical chromium-free composite passivation solution was prepared from ammonium molybdate, nanosilica sol, tannic acid, and silane coupling agents KH151 and KH792.

An electrochemical investigation of the formation of CoSx and its effect on the anodic dissolution of iron in ammoniacal-carbonate solutions [PDF]
, 2013 It has been found that the co-presence of cobalt (II) and thiosulphate ions in ammoniacal-carbonate solutions promotes the passivation of iron, under conditions in which it would otherwise continue to dissolve anodically. Electrochemical experiments have

, 2023 The efficiency of the industrial back surface field (BSF) solar cells is limited by the strong recombination at the rear surface of the solar cell. The enormous number of dangling bonds on the silicon surface create recombination centers, trap the charge

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Journal of Medical Ethics, 2005 The idea of passive euthanasia has recently been attacked in a particularly clear and explicit way by an “Ethics Task Force” established by the European Association of Palliative Care (EAPC) in February 2001. It claims that the expression “passive euthanasia” is a contradiction in terms and hence that there can be no such thing.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

New methods for investigation of surface passivation layers for crystalline silicon solar cells [PDF]
, 2014 One of the main challenges of the c-Si PV industry is the implementation of high quality surface passivation layers. Effective surface passivation is needed in order to avoid large efficiency losses when moving towards thinner silicon wafers and to ...
