The Energy Cost of the Excretion of Urine [PDF]

open access: yes, 1931
The energy consumption of the kidney has been estimated by a number of experimenters and by different methods; and the values obtained are all of the same order of magnitude.

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

open access: yesFEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Ab initio RNA folding

open access: yes, 2014
RNA molecules are essential cellular machines performing a wide variety of functions for which a specific three-dimensional structure is required. Over the last several years, experimental determination of RNA structures through X-ray crystallography and

Label-free shotgun proteomics and metabolite analysis reveal a significant metabolic shift during citrus fruit development. [PDF]

open access: yes, 2011
Label-free LC-MS/MS-based shot-gun proteomics was used to quantify the differential protein synthesis and metabolite profiling in order to assess metabolic changes during the development of citrus fruits.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The effects of lead on photosynthesis, 14C distribution among photoassimilates and transpiration of maize seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
Roots of whole 3 week-old seedlings of maize were exposed for 24 h to a solution of PbCl2. The concentrations of Pb were: 0, 200, 400, 800, 1200, 2400 mg dm-3. The amount of Pb taken up by roots was independent of the concentration of this element in the

Functional characterization of hexokinases in the moss Physcomitrella patens [PDF]

open access: yes, 2005
Carbohydrates are important nutrients and structural components in all living organisms. In plants they affect the developmental and metabolic processes throughout the plant life cycle.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Abscisic acid as a factor in regulation of photosynthetic carbon metabolism of pea seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
The influence of abscisic acid (ABA) on carbon metabolism and the activity of ribulosebisphosphate (RuBP) and phosphoenolpyruvate (PEP) carboxylases in 8-day-old pea seedlings was investigated.
