These data suggest that hyposelenemia in HD patients correlated with euthyroid sick syndrome with low T3 levels, and nutritional status with hyperlipidemia and hypoalbuminemia which might be involved in dysfunction in the endocrine and nutrition metabolism in dialysis patients.

This study was conducted to explore the effect of adipose-derived stem cells (ASCs) on the graft survival rates of fat particles in rabbits. Six domestic rabbits were used for a 3-month study; 1.4 grams of fat tissues were harvested from the bilateral inguinal regions of each animal. They were cut into granules and divided into three parts (A = 0.4 g, B = 0.4 g, and C = 0.6 g). Part A was centrifuged after 0.075% collagenase digestion for isolation of the stromal vascular fraction (SVF). About 0.2 grams of SVF containing ASCs was obtained, and then incorporated with part B to create a treated group, whereas part C was treated as a control group. The tissues in both groups were randomly transplanted into a subcutaneous space that had been created on each side of the dorsal midline of the rabbit. The grafts were taken out after 3 months for calculation of the survival rates. The graft survival rate in the treated group was 23.56 ± 2.49%, while that in the control group was 11.06 ± 2.10%. The graft survival rate in the treated group increased significantly, compared with in the control group (p < 0.01). Improved transplantation effects may be obtained by implanting the fat particles mixed with ASCs. It is suggested that this approach has the potential for becoming a new method of fat graft in clinical practice.

Within determinant quantum Monte Carlo simulation, it is found that the armchair graphene nanoribbons show carrier mediated magnetic correlation. The antiferromagnetic correlation dominates around half filling, while the ferromagnetic correlation dominates as electron filling is lower than 0.8. As the ferromagnetic properties sensitively depend on electron fillings, it may be manipulated by electric gates. Moreover, the ferromagnetic correlation is strengthened markedly as the next-nearest-neighbor hopping energy increases. The predicted manipulation of ferromagnetic correlation may be realized in armchair graphene nanoribbons and ultracold atoms system.

Wire arc additive manufacturing (WAAM) technology was used to produce samples of a 2.25Cr1Mo0.25V heat-resistant steel. The phase composition, microstructure, and crystal structure of the investigated material in the as-cladded state and postcladding heat-treated (705°C × 1 h) state were analysed by optical emission spectrometry (OES), optical microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The properties of the investigated material in the as-cladded state and postcladding heat-treated (705°C × 1 h) state were determined by a microhardness tester, mechanical properties tester, and Charpy impact tester. Through a study of the microstructure and properties, it is found that the investigated material produced by WAAM exhibits good forming quality and excellent metallurgical bonding properties, and no obvious defects are found. The microstructure consists mainly of Bg (granular bainite) and troostite precipitated at the grain boundaries. The results from high-resolution transmission electron microscopy observations show that the crystal structures of the 2.25Cr1Mo0.25V heat-resistant steel samples produced by WAAM in the as-cladded condition have many defects, such as dislocations and martensite-austenite (M-A) constituents, and their grain edges are sharp. There is a dramatic decrease in the dislocations in the 2.25Cr1Mo0.25V heat-resistant steel samples produced by the WAAM condition after the postcladding heat treatment (705°C × 1 h), and the grains become smooth. The distribution of the microhardness in the longitudinal and transverse cross sections of the samples is very uniform. The average longitudinal and transverse microhardness of the samples in the as-cladded state is 310 HV0.5 and 324 HV0.5, respectively. The average longitudinal and transverse microhardness of the samples after post-cladding heat treatment is 227 HV0.5 and 229 HV0.5, respectively. The yield strength of the samples without a postcladding heat treatment is 743 MPa, the tensile strength is 951 MPa, the elongation is 10%, and the Charpy impact value at -20°C is 15 J. After the postcladding heat treatment, the yield strength, tensile strength, elongation, and Charpy impact value of the samples are 611 MPa, 704 MPa, 14.5%, and 70 J, respectively.
