Results indicated that after receiving mutations on the preliminary peptide sequence for optimization, a unique peptide could target C terminal dimerization region of NFAT5 RHR through using its cell penetrating peptide sequence. In conclusion, this is the first study presenting computational evidence on identification of a novel peptide capable of directly targeting NFAT5 dimerization. Besides, future implications of these observations were also discussed in terms of methodology and possible applications.Selective, reversible and tailored adsorption of CO2 from gas mixture is always demanded to control global warming. We for the first time used P-decorated C24N24 fullerene for selective separation of CO2 from N2/CO2 mixture in the presence of an electric field by using density functional theory methods. The computed geometrical parameters evince that the binding distances and bond angles (OCO) are remarkably reduced in electric field and that transformed the physisorption to chemisorption by increasing the field from 0.012 to 0.013 au. The adsorption/desorption of CO2 over the substrate can be easily controlled by switching on and off the electric field. This study reveals that P@C24N24 is a selective adsorbent of CO2 from N2/CO2 mixture and will help the future synthesis of selective, controllable and regenerable adsorbent for the CO2 separation from gas mixture in presence of electric field.Biologically inspired peptide- and protein-based materials are at the forefront of organic bioelectronics research due to their inherent conduction properties and excellent biocompatibility. Peptides have the advantages of structural simplicity and ease of synthesis providing credible prospects for mass production, whereas naturally expressed proteins offer inspiration with many examples of high performance evolutionary optimised bioelectronics properties. We review recent advances in the fundamental conduction mechanisms, experimental techniques and exemplar applications for the bioelectronics of self-assembling peptides and proteins. Diverse charge transfer processes, such as tunnelling, hopping and coupled transfer, are found in naturally occurring biological systems with peptides and proteins as the predominant building blocks to enable conduction in biology. Both theory and experiments allow detailed investigation of bioelectronic properties in order to design functionalized peptide- and protein-based biomaterials, e.g. to create biocompatible aqueous electrodes. We also highlight the design of bioelectronics devices based on peptides/proteins including field-effect transistors, piezoelectric energy harvesters and optoelectronics.
To improve therapy outcome of Yttrium-90 selective internal radiation therapy (
Y SIRT), patient-specific post-therapeutic dosimetry is required. For this purpose, various dosimetric approaches based on different available imaging data have been reported. The aim of this work was to compare post-therapeutic 3D absorbed dose images using Technetium-99m (
Tc) MAA SPECT/CT, Yttrium-90 (
Y) bremsstrahlung (BRS) SPECT/CT, and
Y PET/CT.

Ten SIRTs of nine patients with unresectable hepatocellular carcinoma (HCC) were investigated. The
Tc SPECT/CT data, obtained from
Tc-MAA-based treatment simulation prior to
Y SIRT, were scaled with the administered
Y therapy activity. 3D absorbed dose images were generated by dose kernel convolution with scaled
Tc/
Y SPECT/CT,
Y BRS SPECT/CT, and
Y PET/CT data of each patient. Absorbed dose estimates in tumor and healthy liver tissue obtained using the two SPECT/CT methods were compared against
Y PET/CT.

The percentage deviation of tumor absorbed dose estimates from
Y PET/CT values was on average -2±18% for scaled
Tc/
Y SPECT/CT, whereas estimates from
Y BRS SPECT/CT differed on average by -50±13%. For healthy liver absorbed dose estimates, all three imaging methods revealed comparable values.

The quantification capabilities of the imaging data influence
Y SIRT tumor dosimetry, while healthy liver absorbed dose values were comparable for all investigated imaging data. When no
Y PET/CT image data are available, the proposed scaled
Tc/
Y SPECT/CT dosimetry method was found to be more appropriate for HCC tumor dosimetry than
Y BRS SPECT/CT based dosimetry.
The quantification capabilities of the imaging data influence 90Y SIRT tumor dosimetry, while healthy liver absorbed dose values were comparable for all investigated imaging data. When no 90Y PET/CT image data are available, the proposed scaled 99mTc/90Y SPECT/CT dosimetry method was found to be more appropriate for HCC tumor dosimetry than 90Y BRS SPECT/CT based dosimetry.The executive control network is involved in novel situations or those in which prepotent responses need to be overridden. Previous studies have demonstrated that when control is exerted, conscious perception is impaired, and this effect is related to the functional connectivity of fronto-parietal regions. In the present study, we explored the causal involvement of one of the nodes of this fronto-parietal network (the right Supplementary Motor Area, SMA) in the interaction between executive control and conscious perception. read more Participants performed a dual task in which they responded to a Stroop task while detecting the presence/absence of a near-threshold Gabor stimulus. Concurrently, transcranial magnetic stimulation (TMS) was applied over the right SMA or a control site (vertex; Experiment 1). As a further control, the right Frontal Eye Field (FEF) was stimulated in Experiment 2. Diffusion-weighted imaging (DWI) tractography was used to isolate the three branches of the superior longitudinal fasciculus (SLF I, II and III), and the frontal aslant tract (FAT), and to explore if TMS effects were related to their micro- and macrostructural characteristics. Results demonstrated reduced perceptual sensitivity on incongruent as compared to congruent Stroop trials. A causal role of the right SMA on the modulation of perceptual sensitivity by executive control was only demonstrated when the microstructure of the right SLF III or the left FAT were taken into account. The volume of the right SLF III was also related to the modulation of response criterion by executive control when the right FEF was stimulated. These results add evidence in favor of shared neural correlates for attention and conscious perception in fronto-parietal regions and highlight the role of white matter in TMS effects.
