$B \to \pi\pi$ Decay in QCD

open access: yes, 2000
A new method is suggested to calculate the $B\to \pi\pi$ hadronic matrix elements from QCD light-cone sum rules. To leading order in $\alpha_s$ and $1/m_b$, the sum rule reproduces a factorizable matrix element, in accordance with the prediction of the ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Detection of Wolbachia bacterium in Iranian strain of Trichogramma brassicae (Hym., Trichogrammatidae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2013
Wolbachia (α-proteobacteria) strains are intracellular endosymbiont bacteria found in reproductive tissues of many arthropod species. In Trichogramma wasps, thelytokous parthenogenesis is mostly induced by this bacterium which inherited transovarially ...

Four-body baryonic decays of $B\to p \bar{p} \pi^+\pi^-(\pi^+K^-)$ and $\Lambda \bar{p} \pi^+\pi^-(K^+K^-)$

open access: yes, 2017
We study the four-body baryonic $B\to {\bf B_1 \bar B_2}M_1 M_2$ decays with $\bf B_{1,2}$ ($M_{1,2}$) being charmless baryons (mesons). In accordance with the recent LHCb observations, each decay is considered to proceed through the $B\to M_1 M_2 ...

PICALM::MLLT10 translocated leukemia

open access: yesFEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

New Measurements of Cabibbo-Suppressed Decays of D Mesons in CLEO-c

open access: yes, 2005
Using 281 pb^-1 of data collected with the CLEO-c detector, we report on first observations and new measurements of Cabibbo-suppressed decays of D mesons to 2, 3, 4, and 5 pions.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
