Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Dependence of the legume seeds vigour on their maturity and method of harvest

open access: yesActa Societatis Botanicorum Poloniae, 2014
Several methods were used to study 'the vigour and viability of legume seeds (Pisum sativum L. cv. Hamil, Piston arvense L. cv. Mazurska and Lupinus luteus L. cv. Tomik) harvested at three main stages of seed repening (green, wax and full).

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

open access: yesFEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

Effect of ultra-drying on storability and vigour of onion seeds

open access: yesVegetable Science, 2020
Onion seeds are poor storers they have one of the loweststorability among cultivated crops. Seed moisture is one ofthe critical factors which determines the seed storability.The effect of ultra-drying of onion seeds on seed storabilityand seed vigour was studied.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Effect of different treatment on removing seed dormancy to induction of seed emergence and vigour in some populations of four species of savory (Satureja spp.) [PDF]

open access: yesعلوم و فناوری بذر ایران, 2017
In greenhouse experiment, the seed samples of 8 populations of four savory sepecies as: Satureja sahendica, S.bachtiarica , S.khuzistanicaandS.hortensis were treated with cold strafication, after-ripening, physical scarification (sand paper), chemical ...
