OBJECTIVE To investigate the relationships between self-reported and objectively measured cognitive function prior to systemic therapy and subsequent well-being outcomes over 24 months in older breast cancer survivors. METHODS Data were from 397 women aged 60 to 98 diagnosed with non-metastatic breast cancer in the Thinking and Living with Cancer Study recruited from 2010-2016. Cognitive function was measured at baseline (following surgery, prior to systemic therapy) using neuropsychological assessments of attention, processing speed, and executive function (APE), learning and memory (LM), and the self-reported FACT-Cog scale. Well-being was measured using the FACT-G functional, physical, social, and emotional well-being domain scales at baseline and 12 and 24 months later, scaled from 0 (low) to 100 (high). Linear mixed-effects models assessed the relationships between each of baseline APE, LM, and FACT-Cog quartiles with well-being scores over 24 months, adjusted for confounding variables. RESULTS At baseline, older survivors in the lowest APE, LM, and FACT-Cog score quartiles experienced poorer global well-being than those in the highest quartiles. At 24 months, older survivors tended to improve in well-being, and there were no differences according to baseline APE or LM scores. 5(NEthylNisopropyl)Amiloride At 24 months, mean global well-being was 80.3 (95% CI 76.2-84.3) among those in the lowest vs 86.6 (95% CI 83.1-90.1) in the highest FACT-cog quartile, a clinically meaningful difference of 6.3 points (95% CI 1.5-11.1). CONCLUSIONS Among older breast cancer survivors, self-reported, but not objective cognitive impairments, were associated with lower global well-being over the first 2 years of survivorship. © 2020 John Wiley & Sons, Ltd.The incidence of mesenchymal tumors in the salivary gland range from 0.3-1%1 .

These images can be obtained using the collapsed FatNav, a previously introduced navigator for prospective motion correction. It combines a short duration with wide compatibility with different main sequences due to its robustness against spin history effects. THEORY AND METHODS A projection-based 3D/2D registration method is presented and then modified to take into account the peculiarities of the collapsed FatNav. Water/fat separated volumes were used in simulations to assess the accuracy of the proposed method at different resolutions by comparison with high-resolution 3D registration. The sensitivity with respect to masking strategies and starting motion parameters was investigated. Finally, prospective experiments with a healthy volunteer were performed with different types of motion patterns. A PROPELLER main sequence was chosen to compare the prospective correction with PROPELLER's own retrospective correction. RESULTS In the simulations the proposed method has shown comparable performance to 3D registration. Furthermore, evidence of its robustness with respect to masking strategies and starting motion parameters was presented. The combination with collapsed FatNav has performed well in correcting most of the motion artifacts prospectively with improved image quality compared to only using PROPELLER's retrospective motion correction. CONCLUSIONS The proposed 3D/2D registration together with collapsed FatNav is characterized by a good balance between navigator duration and estimate accuracy. Further work is needed to validate the method across a wider variety of subject anatomies. © 2020 International Society for Magnetic Resonance in Medicine.Pseudo-isocyanine chloride (PIC) is a dyestuff which self-assembles in aqueous solution, thereby showing a characteristic and sharp absorption band as well as a fluorescence band at a wavelength of 573 nm. Based on this unique feature, a synthetic model system was developed, suitable to analyse self-assembly in various environments like macromolecular crowding. First, Triethylene glycol (TEG), polyethylene glycol (PEG), Ficoll 400 as a highly branched polysaccharide and sucrose corresponding to the monomeric unit of Ficoll were used as potential crowders. Combined UV-Vis spectroscopy and time-resolved light scattering revealed a strong impact of crowding based on excluded volume effects only for Ficoll 400. Sucrose had hardly any influence on the self-assembly of PIC and PEG and TEG impeded the PIC self-assembly. Finally, HeLa cells were infiltrated with PIC solutions well below the aggregation threshold in the infiltrating solution. In the cellular environment, PIC was exposed to a significant crowding and immediately started to aggregate. As was demonstrated by fluorescence imaging, the extent of aggregation could be modulated by exposing the cells to salt-induced osmotic stress. The results suggest future use of such a system as a sensor for the analysis of in vitro and in vivo crowding effects on self-assembly processes. © 2020 WILEY-VCH Verlag GmbH & Co.

Incorporation of a responsive linker between the lipid anchor and the polymer chain can be of interest to avoid indefinite binding of the conjugates to hydrophobic pockets of serum proteins or phospholipid membranes when reaching a target cell or tissue. Here, the synthesis of pH-sensitive lipid-polymer conjugates by reversible addition-fragmentation chain transfer (RAFT) polymerization using a RAFT chain transfer agent that is equipped with a pH-sensitive ketal bond between a cholesterol moiety and the trithiocarbonate RAFT chain transfer group is reported. It is demonstrated that in native form these conjugates exhibit a high affinity to albumin and cell membranes but loose this ability in response to a mild acidic trigger in aqueous medium. © 2020 WILEY-VCH Verlag GmbH & Co.
