Effects of 1,25-dihydroxyvitamin D3 and vitamin D3 on the expression of the vitamin d receptor in human skeletal muscle cells.

Rachele M Pojednic et al.

Calcified tissue international, 96(3), 256-263 (2014-12-07)

Vitamin D receptor (VDR) expression and action in non-human skeletal muscle have recently been reported in several studies, yet data on the activity and expression of VDR in human muscle cells are scarce. We conducted a series of studies to

Gene expression profiling of giant cell tumor of bone reveals downregulation of extracellular matrix components decorin and lumican associated with lung metastasis.

M Lieveld et al.

Virchows Archiv : an international journal of pathology, 465(6), 703-713 (2014-10-12)

Giant cell tumor of bone (GCTB) displays worrisome clinical features such as local recurrence and occasionally metastatic disease which are unpredictable by morphology. Additional routinely usable biomarkers do not exist. Gene expression profiles of six clinically defined groups of GCTB

Comparison of oxidation kinetics of nitrite-oxidizing bacteria: nitrite availability as a key factor in niche differentiation.

Boris Nowka et al.

Applied and environmental microbiology, 81(2), 745-753 (2014-11-16)

Nitrification has an immense impact on nitrogen cycling in natural ecosystems and in wastewater treatment plants. Mathematical models function as tools to capture the complexity of these biological systems, but kinetic parameters especially of nitrite-oxidizing bacteria (NOB) are lacking because

Water in Photosystem II: structural, functional and mechanistic considerations.

Katrin Linke et al.

Biochimica et biophysica acta, 1837(1), 14-32 (2013-08-28)

Water is clearly important for the functioning of Photosystem II (PSII). Apart from being the very substrate that needs to be transported in this water oxidation enzyme, water is also vital for the transport of protons to and from the

Widespread decline of Congo rainforest greenness in the past decade.

Liming Zhou et al.

Nature, 509(7498), 86-90 (2014-04-25)

Tropical forests are global epicentres of biodiversity and important modulators of climate change, and are mainly constrained by rainfall patterns. The severe short-term droughts that occurred recently in Amazonia have drawn attention to the vulnerability of tropical forests to climatic
