Analysis of the relationship between start of the rainy season and farmer's soving date in the Niamey area and its impacts on the pearl millet yield [PDF]
, 2009 Relationship between start of the rainy season and farmer's planting date have been analysed at local scale through (i) in situ daily rainfall records and (ii) agronomical measurement provided by on-farm survey at plot scale for 10 villages network ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Recycling probability and dynamical properties of germinal center reactions
, 2001 We introduce a new model for the dynamics of centroblasts and centrocytes in a germinal center. The model reduces the germinal center reaction to the elements considered as essential and embeds proliferation of centroblasts, point mutations of the ...

Experimental characterization and modelling of a cavitating centrifugal pump operating in fast start-up conditions [PDF]
, 2010 The start-up of rocket engine turbopumps is generally performed only in a few seconds. It implies that these pumps reach their nominal operating conditions after only a few rotations.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
FEBS Letters, EarlyView.Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Ethnic Minority Self-Employment in Germany: Geographical Distribution and Determinants of Regional Variation [PDF]
In Germany self-employment among foreigners increased significantly in recent years. We study the geographical distribution of ethnic minority self-employment in Germany and find determinants for variations in start-up activities across 440 ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
