The remarkable dynamic regulation of assembly process, together with the NSC differentiation on twisted nanofibers are making this system an ideal model to interpret complex proteins fibrillation processes and investigate the structure-function relationship.Next-generation energy storage devices such as lithium-sulfur batteries (LSBs) face several challenges including fast charging and high-power delivery. Thus, it is necessary to improve the stability of the electrodes with efficient electrochemical system. In this work, a durable sulfur cathode even at high rates is enabled via lean binder content. The binder consists of a chitosan cross-linked with a carboxylated nitrile-butadiene rubber (XNBR), which exhibits high affinity toward lithium polysulfide along with robust mechanical properties because of the synergistic effect of the polar chitosan and the elastomeric XNBR. Despite using extremely small content of binder (3 wt%), the LSB shows a highly stable long-term cycling performance with capacity retention decay values of 0.026% and 0.029% after 500 cycles at 5 and 10 C. Moreover, the cell shows an outstanding specific capacity of 228 mAh g-1 at an ultrahigh charge-discharge rate of 20 C. This approach may significantly improve the design of the sulfur cathode and pave a facile way to fabricate commercially viable next-generation energy storage devices.In humans B-symptoms refer to systemic symptoms of lymphoma such as fever, weight loss, and night sweats and influence the prognosis of patients. In canine lymphoma, substage B is used to describe any clinical sign observed. Aim of the retrospective study was to compare the prognostic value of substage B with B-symptoms to predict treatment response and survival in canine nodal diffuse large B-cell lymphoma. Affected dogs treated with CHOP chemotherapy between 2008 and 2019 were included. B-symptoms were defined by weight loss greater than 10% of normal weight, fever and the occurrence of unexplained resting tachypnoea substituted human night sweats. Substage B was defined as any symptoms but lymphadenopathy. Fifty-five cases were included. B-symptoms were present in 20/55 (36%) and substage B in 40/55 (74%) patients. No significant associations between B-symptoms or substage B and weight, sex, breed, WHO stage and lymphoma grade were found. Treatment response was negatively associated with both substage B (P = .02) and B-symptoms (P = .001). Tamoxifen chemical B-symptoms significantly decreased progression free survival (PFS) (95 vs 330 days, P = .001) and lymphoma specific survival (LSS) (160 vs 462 days, P = .001). Data showed that B-symptoms might be a more reliable prognostic indicator than substage B in canine nodal diffuse large B-cell lymphoma. Prospective studies assessing B-symptoms in a larger cohort of patients and in other common lymphoma types are warranted. The abstract was presented at the fourth meeting of the European Canine Lymphoma Network Group in Lugano, 22 June 2019 and published in the proceeding of the meeting on the page 26.
To determine the effect of a comprehensive nurse-led programme for patients with chronic non-malignant pain, on quality of life, level of pain, anxiety, and depression, as primary outcomes and patients' satisfaction as a secondary end point.
An open-label randomized controlled trial was carried out.
The experimental group received both a nurse-led intervention on healthy lifestyles, education on self-esteem, pain awareness, communication, and relaxation techniques. The control group received usual care. Quality of life, level of pain, anxiety, and depression were the main outcomes. Data were obtained at baseline, immediately after the intervention, and 6 and 9months. The study was carried out from 2015-2017.
The sample was composed of 279 patients. At 9months, the effect size (non-parametric effect size statistic A) favoured the intervention group for SF-36 mental health score (A=0.79; 95% CI 0.73-0.85), anxiety (A=0.58; 95% CI 0.51-0.65), pain intensity (A=0.57; 95% CI 0.51-0.64), and depression (A=0led intervention improved their mental health and decreased their level of pain.
This study aimed to develop a high-dose-rate brachytherapy (HDR-BT) quality assurance (QA) tool for verification of source positions, and to report on its effectiveness.
We fabricated a cuboid phantom measuring 30×30×3cm
with spaces to embed Fletcher-Williamson tandem and ovoid applicators. Lead-based, cylindrically shaped radiopaque markers, which scatter radiation and blacken the Gafchromic
RTQA2 films placed on the applicators, were inserted into the phantom to determine the applicator tip and reference source positions. A three-dimensional image-guided brachytherapy (3D-IGBT) plan was generated, and the source positions on the film and radiation treatment planning system (RTPS) were verified with the tool. Source position errors were evaluated as the distance in the applicator axis direction between the source position and the center position of two radiopaque marker pairs.
Source position errors on the film and RTPS were in good agreement with one another and were all within 0.5mm for all applicators. Offset values of each applicator were in good agreement with the value determined in treatment planning (6mm). The expanded measurement uncertainty of our QA tool was estimated to be 0.87mm, with a coverage factor k of 2.
Our new HDR-BT QA tool developed for comprehensive source position verification will be useful for cross checking actual source positions and planned source positions on the RTPS.

Twenty-four children patients (M/F 17/7) undergoing HSCT in a single center over a period of 1 year were included in the study. The presence of BKV DNA was determined by quantitative real-time PCR in plasma and urine samples at the following times before transplantation, twice a week until engraftment time, and weekly for + 100 days. The mean age of the patients was 7.79 ± 5.03 years, the mean follow-up time was 95.6 ± 25.9 days, and the average number of samples per patient was 15.8 ± 3.2. BKV DNA was detected in at least one urine sample in 91.6% (n 22) and at least one plasma sample in 75% (n18) of the patients. The median time to the first BKV DNA positivity in urine and plasma samples was 11 (range 1-80) and 32 days (range 2-79), respectively. The median value of BKV DNA copies in urine and plasma were 1.7 × 106 (range 2.8 × 101 -1.2 × 1014 ) and 1.9 × 103 copies/mL (range 3-2.1 × 106 ), respectively.
