The variance of quasar counts in cells [PDF]
The Astrophysical Journal, 1994 {}From three quasar samples with a total of 1038 objects in the redshift range $1.0 2.2$ we measure the variance $ ^2$ of counts in cells of volume $V_u$. By a maximum likelihood analysis applied separately on these samples we obtain estimates of $ ^2(\ell)$, with $\ell \equiv V_u^{1/3}$.

T cells count and then decide [PDF]
The Journal of Cell Biology, 2008 ![][1] T cells (green) interact (left) with antigen-bearing DCs (red). T cells spend little time with DCs (filled triangles, right) that carry little antigen but linger longer (open triangles) when high antigen–density DCs are also present.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Improvement of cell counting method for Neubauer counting chamber [PDF]
Journal of Clinical Laboratory Analysis, 2019 AbstractBackgroundWe compared the cell counting accuracy of the conventional method and the improved method by using Neubauer counting chamber.MethodsIn the improved method, all the border cells were counted and then divided by two; while, in the conventional method, only border cells on the two boundaries (top and left) were counted.ResultsAbout 55 ...

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
