Effects of Priming by Salicylic Acid on Yield and Growth Indices of Safflower (Carthamus tinctorus L.) Plants Under end Season Drought Stress [PDF]

open access: yesJournal of Agricultural Science and Sustainable Production, 2012
Salicylic acid is a plant hormone which had enhancing effects on growth and yield of plants under different environmental conditions. It is proposed, salicylic acid could be used as growth regulator for improving plant growth under water stress ...

Screen Position Preference Offers a New Direction for Action Observation Research: Preliminary Findings Using TMS

open access: yesFrontiers in Human Neuroscience, 2018
Action observation has been suggested to be an effective adjunct to physical practice in motor (re)learning settings. However, optimal viewing conditions for interventions are yet to be established.

Space Vector Modulation Techniques for Common-Mode Voltage Reduction in Three-Phase Transformerless Split-Source Inverters

open access: yesEletrônica de Potência, 2020
Photovoltaic (PV) systems with low input voltage usually employ an input boost converter and an output inverter. Regarding to this issue, the split-source inverter (SSI) provides a single power conversion stage which aggregates boost capability with low

Interferon beta drives therapy resistance in a patient‐derived model of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Heritability of language laterality assessed by functional transcranial Doppler ultrasound: a twin study [version 2; peer review: 1 approved, 2 approved with reservations]

open access: yesWellcome Open Research, 2020
Background: Prior studies have estimated heritability of around 0.25 for the trait of handedness, with studies of structural brain asymmetry giving estimates in a similar or lower range.

CEACAM1 participation in breast cancer progression

open access: yesMolecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Efficient storage, retrieval and analysis of poker hands: An adaptive data framework

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
In online gambling, poker hands are one of the most popular and fundamental units of the game state and can be considered objects comprising all the events that pertain to the single hand played.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
