AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A review. This research group is working towards understanding the fundamental physicochem. mechanisms of trace metal biouptake by aquatic microorganisms in natural systems. Research is currently focused on identifying under what conditions uptake fluxes a ...
The efficacy and success of many cellular processes is dependent on a tight orchestration of proteins trafficking to and from their site(s) of action in a time-controlled fashion. Recently, a dynamic cycle of palmitoylation/de-palmitoylation has been shown ...
Natural colloids are defined as macromolecules and nanoparticles with sizes ranging between 1 nm and 1 µm. Colloidal pool is complex "ill-defined" mixture of humic substances, exopolymeric substances (EPS), inorganic oxides, clays, etc. Aquatic colloids ha ...
Chromatography is increasingly being used for large-scale preparative separation of precious biological components such as recombinant proteins and DNA. Several kinds of mathematical models are used to describe the liquid chromatography process. The aim of ...
Liquid–liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of t ...
Colloidal organic matter (COM) collected in small and large watercourse tributaries of the Negro River (Brazil) were fractionated and characterized by an asymmetrical flow field-flow fractionation (AFIFFF) coupled to UV and seven angle laser light scatteri ...
Angiotensin-I-converting enzyme (ACE) inhibitory activity was identified in milk proteins fermented with Lactobacillus (Lb.) helveticus NCC 2765 (Nestle Culture Collection, Vers-chez-les-Blanc, Switzerland). Hydrolyzing sodium caseinate for 1 and 2 h inhib ...
Due to the growing interest on micro total analytical system (μTAS), fast analysis of small amount samples with high throughout is highly desired. Conventional separation techniques, such as Liquid Chromatography, show a great potential for miniaturisation ...
Ion beam LIGA allows the etching of 3D nano-structures by direct writing with a nano-sized beam. However, this is a relatively time consuming process. We propose here another approach for etching structures on large surfaces and faster, compared to the dir ...
Prenatal exposure to mercury causes neurodevelopmental disorders and neurological pathologies in infants, such as microcephaly and mental retardation. Despite critical importance, the molecular interactions leading to mercury toxicity are yet to be elucida ...
