Measurement of the Ratios of Branching Fractions B(Bs->Ds- pi+)/B(B0->D-pi+) and B(B+->D0bar pi+)/B(B0->D-pi+)

open access: yes, 2005
We report an observation of the decay Bs -> Ds- pi+ in p pbar collisions at sqrt(s) = 1.96 TeV using 115 pb^(-1) of data collected by the CDF II detector at the Fermilab Tevatron. We observe 83 +/- 11 Bs -> Ds- pi+ candidates, representing a large increase in statistics over previous measurements and the first observation of this decay at a p pbar ...

Fine and physical mapping toward the positional cloning of an indica-derived blast resistance gene Pi-b

open access: yes, 1996
This article 'Fine and physical mapping toward the positional cloning of an indica-derived blast resistance gene Pi-b' appeared in the International Rice Research Notes series, created by the International Rice Research Institute (IRRI) to expedite communication among scientists concerned with the development of improved technology for rice and rice ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Polarization and quantum entanglement effects in $$B^\pm _c\rightarrow J/\psi +\pi ^\pm +\pi ^0$$ B c ± → J / ψ + π ± + π 0 process

open access: yesEuropean Physical Journal C: Particles and Fields
Motivated by the very recent observation of the $$B^+_c\rightarrow J/\psi +\pi ^+ +\pi ^0$$ B c + → J / ψ + π + + π 0 decay using proton–proton collision data by the LHCb collaboration, we study the four-body angular distributions and the quantum ...

B -> pi, B(s) -> K form factors and Vub determination

open access: yes, 2008
We present a QCD light-cone sum rule (LCSR) estimation of the B -> pi, B -> K, and Bs -> K form factors calculating gluon radiative corrections at next-to-leading order. The MS-bar b-quark mass is used, instead of the one-loop pole mass employed in the previous analyses.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

First observation of the decays (B)over-bar((s))(0) -> Ds+K-pi(+)pi(-) and (B)over-bar((s))(0) -> Ds(1)(2536)(+)pi(-)

open access: yes, 2012
The first observation of the decays (B) over bar (0)(s) -> Ds+K-pi(+)pi(-) and (B) over bar (0)(s) -> Ds+K-pi(+)pi(-) are reported using an integrated luminosity of 1.0 fb(-1) recorded by the LHCb experiment.

Hunting for the alpha: $B\to \rho\rho$, $B \to \pi\pi$, $B \to\pi\rho$

open access: yes, 2005
The hypothesis of the smallness of penguin contribution to charmless strangeless $B_d (\bar B_d)$ decays allows to determine with high accuracy the value of angle $\alpha$ from the currently available $B \to \rho\rho$, $B \to \pi\pi$ and $B\to \rho\pi$ decay data.
