Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Active Commuting and Active Transportation

open access: yes, 2022
This book focuses on active transport as a way to increase physical activity levels. Active commuting and active transportation on foot or by bicycle create opportunities for physical activity, provide transportation options for those without a car ...

Active Transport and Metabolism

Protoplasma, 1967
By definition active transport requires metabolic energy. In most cases of active transport, however, the energy consumption is too small to give a measureable contribution to the overall energy consumption of the cell. In such cases the active nature of the transport must be inferred from, for instance, net transport against an electrocbemical ...

Active membranes for active transport

Journal of Theoretical Biology, 1967
Abstract A model is proposed wherein membrane subunit ingestion accounts for observed membrane function in active transport. Biological significance is given to the known rapid rate of synthesis of cell membranes, the role of calcium ion in providing membrane elasticity and binding energy for the membrane.

Adsorption and active transport

Experientia, 1960
On demontre l'identite formelle de l'equation de Langmuir (pour l'adsorption) et de celle de Michaelis-Menten, toutes deux fondees sur la loi de «mass action». Cette demonstration justifie la vue d'apres laquelle l'accumulation des ions par les cellules vivantes selon la loi de Michaelis-Menten represente une liaison d'adsorption au niveau ...

Active ion transport by mitochondria

Protoplasma, 1967
The ability of isolated mitochondria to accumulate very large amounts of Ca++ by an active transport mechanism was discovered by V a s i n g t o n and M u r p h y in 1961 [1]. The accumulation process was found to be blocked by respiratory inhibitors and by uncouplers of oxidative phosphorylation, and thus was completely dependent on electron transport

Active Transport and Heat

Asia Pacific Journal of Public Health, 2011
Increasing heat may impede peoples’ ability to be active outdoors thus limiting active transport options. Co-benefits from mitigation of and adaptation to global warming should not be assumed but need to be actively designed into strategies.

Secondary Active Transporters

2019
Transport of solutes across biological membranes is essential for cellular life. This process is mediated by membrane transport proteins which move nutrients, waste products, certain drugs and ions into and out of cells. Secondary active transporters couple the transport of substrates against their concentration gradients with the transport of other ...
