Effects of Heavy Metal Cr（Ⅵ）on the Growth and Ecophysiology of Mangrove Avicennia marina Seedlings [PDF]

, 2008
采用砂基栽培，研究重金属Cr(Ⅵ)在不同浓度梯度和不同胁迫处理阶段（种苗期和幼苗期）及胁迫处理时间条件下对红树植物白骨壤（Avicenniamarina）幼苗的生长及生理生态效应的影响。设置Cr(Ⅵ)胁迫浓度系列为1.0、2.5、5.0、7.5、10.0、15.0、20.0mg·L-1，以不加Cr(Ⅵ)为对照，培养基海水盐度均为15‰，培养期分为45d和150d。实验期间全程记录及观测各胁迫组白骨壤种苗萌发及幼苗生长状况，定期记录幼苗的高度生长、叶片大小 ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

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

FEBS 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 ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Adsorption of phosphate and Cr(Ⅵ) by biochar-loaded Zn-Al layered double hydroxide

Gongye shui chuli
Reed straw biochar-loaded zinc-aluminum layered dihydroxide (ZnAl-LDHs) composites (ZnAl-LDHs@BC) were prepared by liquid-phase co-precipitation. The effects of ZnAl-LDHs mass fraction in the composite, solution pH and coexisting anions on the adsorption

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.
