Lymphangiography to treat postoperative lymphatic leakage: a technical review.
In addition to imaging the lymphatics and detecting various types of lymphatic leakage, lymphangiography is a therapeutic option for patients with chylothorax, chylous ascites, and lymphatic fistula. Percutaneous thoracic duct embolization, transabdominal catheterization of the cisterna chyli or thoracic duct, and subsequent embolization of the thoracic duct is an alternative to surgical ligation of the thoracic duct. In this pictorial review, we present the detailed technique, clinical applications, and complications of lymphangiography and thoracic duct embolization
Epitaxially strained ultrathin LaNiO/LaAlO and LaNiO/SrTiO superlattices: a density functional theory + study
By employing first-principles electronic structure calculations we
investigate nickelate superlattices [LaNiO]/[LaAlO] and
[LaNiO]/[SrTiO] with (001) orientation under epitaxial tensile
strain. Within density functional theory augmented by mean-field treatement of
on-site electronic correlations, the ground states show remarkable dependence
on the correlation strength and the strain. In the weakly and intermediately
correlated regimes with small epitaxial strain, the charge-disproportionated
insulating states with antiferromagneitc order is favored over the other
orbital and spin ordered phases. On the other hand, in the strongly correlated
regime or under the large tensile strain, ferromagnetic spin states with
Jahn-Teller orbital order become most stable. The effect from polar interfaces
in LaNiO]/[SrTiO] is found to be noticeable in our
single-layered geometry. Detailed discussion is presented in comparison with
previous experimental and theoretical studies.Comment: 9 pages, 8 figure
