Organic Fruit Production in Europe [PDF]
, 2002 PART I: SHORT HISTORY OF ORGANIC FARMING The organic fruit production in Europe is not only a matter of statistics, regulations and tables but also has a meaningful historical background.

Climate change: carbon losses in the Alps [PDF]
, 2016 The response of the terrestrial carbon cycle to global change is one of the main uncertainties in current climate change predictions1. Most terrestrial carbon is held in soils as organic matter derived from the decay of plant material (Fig. 1).

Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node
FEBS Open Bio, EarlyView.The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.

The association between organic matter and clay minerals in carbonaceous chondrites [PDF]
, 2001 There is an established relationship between organic matter content and aqueous alteration processes [1,2]. However, the relationship between meteoritic organic matter and individual aqueously generated mineral matrix phases is poorly understood ...

Enantioselective synthesis of chiral amides by carbene insertion into amide N–H bond
Nature CommunicationsChiral amides are important structure in many natural products and pharmaceuticals, yet their efficient synthesis from simple amide feedstock remains challenge due to its weak Lewis basicity.

FEBS Open Bio, EarlyView.Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

Understanding soil nitrogen supply: organic matter quality and quantity [PDF]
, 2002 The soil organic matter (SOM) contents of organic and conventionally farmed soils were compared. Whilst the quantity of SOM was found to be similar with both systems, the quality of SOM differed in respect of higher amounts of N released by the organic ...

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells
FEBS Open Bio, EarlyView.Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

Atrazine Degradation, Sorption and Bioconcentration in Water Systems [PDF]
, 1982 The herbicide atrazine is used extensively to control broadleaf and grass weeds in such crops as sorghum and corn. A small portion of the atrazine may be lost from the area of application by surface runoff and could enter a stream or lake.

Iron-catalyzed alkyne alkylzincation affected by counterions
Nature CommunicationsMetal complex catalysts typically comprise three components: ligands, central metals, and counterions. The counterion profoundly influences the activity and selectivity of numerous catalytic reactions, while such a phenomenon is rarely observed in ...
