Muscle diffusion tensor imaging (mDTI) is a quantitative MRI technique that can provide information about muscular microstructure and integrity. Ultrasound and DTI studies have shown intramuscular differences, and therefore separation of different muscles for analysis is essential. The commonly used methods to assess DTI metrics in muscles are manual segmentation and tract-based analysis. Recently methods such as volume-based tractography have been applied to optimize muscle architecture estimation, but can also be used to assess DTI metrics.

To evaluate diffusion metrics obtained using three different methods-volume-based tractography, manual segmentation-based analysis and tract-based analysis-with respect to their interrater reliability and their ability to detect intramuscular variance.

30 volunteers underwent an MRI examination in a 3 T scanner using a 16-channel Torso XL coil. Diffusion-weighted images were acquired to obtain DTI metrics. These metrics were evaluated in six thigh muscles using volysis showed the lowest coefficients of variation.
Diffusion data can be assessed by volume tractography, standard tractography and manual segmentation with high interrater reliability. Each method produces different results for the investigated DTI parameters. Volume-based tractography was superior to conventional manual segmentation and tractography regarding interrater reliability and detection of intramuscular variance, while tract-based analysis showed the lowest coefficients of variation.
Direct-acting antivirals (DAAs) have dramatically changed the treatment of chronic hepatitis C. Their high efficacy helps in eradicating hepatitis C virus with few adverse events. Information on real-world use of DAAs therapy in patients aged 75years and older is inadequate.

The Japanese DAAs database was constructed in 2014 as a cooperative system between 18 prefectures. The medical reports filled in by doctors and anonymized at the local government office were collected. The patients' demographic features, viral factors, and treatment characteristics were compared among three groups stratified by age when therapy was initiated Group A (<60years old), Group B (60-74years old), and Group C (≥75years old).

Out of the 22,454 patients whose age upon starting therapy could be identified, 24.8% (n=5597) belonged to Group C, which was ten times the number in the Japanese Interferon Database. Female patients, advanced stages of liver fibrosis, and past history of hepatocellular carcinoma treatment were significantly higher in the older age groups (Group A<B<C), whereas sustained virologic response (SVR) rates were not different (91%-93%). In Group C, multivariate logistic regression analysis revealed that predicting factors for virologic response varied among DAAs regimens. However, the completion of DAAs therapy commonly contributed to SVR, regardless of DAAs regimen.

DAAs therapy is associated with high SVR rates, even in the oldest age group, and therapy should not be withheld on the basis of old age.

Infant iron status assessments may be difficult to interpret due to infections. The soluble transferrin receptor (sTfR) has been suggested as a biomarker mainly unaffected by the acute phase response. Reference intervals reflecting dynamics of infant growth first year in life are not well established.

The sTfR and CRP concentrations were measured in samples from 451 term infants with the Roche Cobas platform in umbilical cord, at 48-96hours, 4 and 12months. Reference values were constructed as the 2.5th and 97.5th percentiles. The relationship between CRP concentrations >1mg/L and sTfR was tested by Kendall correlation.

Reference intervals for girls and boys were 2.4-9.5mg/L at birth, 2.9-8.4mg/L at 48-96hours, 2.6-5.7mg/L at 4months and 3.0-6.3mg/L at 12months. No differences between sexes were observed except for at 4months. sTfR did not covariate with CRP concentrations >1mg/L except in 48-96hours samples.

This study reports reference intervals for sTfR from birth to 12months of age in a large group of infants in a low-risk area for iron deficiency. sTfR might add value to infant iron status diagnostics since no covariation with CRP was found at birth, at 4months or at 12months.

A key challenge for these emerging batteries has been the lack of suitable electrode materials, which severely limits their further developments. MXenes, a new class of 2D transition metal carbides, carbonitrides, and nitrides, are proposed as electrode materials for these emerging batteries due to several desirable attributes. These attributes include large and tunable interlayer spaces, excellent hydrophilicity, extraordinary conductivity, compositional diversity, and abundant surface chemistries, making MXenes promising not only as electrode materials but also as other components in the cells of emerging batteries. Herein, an overview and assessment of the utilization of MXenes in rechargeable batteries beyond LIBs, including alkali-ion (e.g., Na+ , K+ ) storage, multivalent-ion (e.g., Mg2+ , Zn2+ , and Al3+ ) storage, and metal batteries are presented. In particular, the synthetic strategies and properties of MXenes that enable MXenes to play various roles as electrodes, metal anode protective layers, sulfur hosts, separator modification layers, and conductive additives in these emerging batteries are discussed. Panobinostat Moreover, a perspective on promising future research directions on MXenes and MXene-based materials, ranging from material design and processing, fundamental understanding of the reaction mechanisms, to device performance optimization strategies is provided.
