Molecular, chromosomal, and morphological evidence reveals a new allotetraploid fern species of (Aspleniaceae) from southern Jiangxi, China.

, a new tetraploid fern species of the complex (Aspleniaceae) from Jiulianshan National Nature Reserve, southern Jiangxi, China is described and illustrated. We inferred the phylogenetic position of the new species based on sequences from seven plastid markers (, , , , , , and ) and one low-copy nuclear gene, . The plastid phylogeny supported a close relationship among the new species , , and , while the nuclear phylogeny differed in topology from the plastid tree.

Author Correction: Review of the genus (Anura: Megophryidae), with revalidation of and description of a new species from China.

Following the publication of our paper (Li et al., 2020), it has come to our attention that, due to our oversight, the contributions of some colleagues were not reflected in the "ACKNOWLEDGEMENTS" section. Hereby, we wish to add the following to the "ACKNOWLEDGEMENTS" section as a correction.

Review of the genus (Anura: Megophryidae), with revalidation of and description of a new species from China.

The genus-level recognition of monophyletic short-legged toads ( ) has been recently implicated in the taxonomic debate of . In the present study, is reasonably regarded as a distinct genus based on significant morphological differentiations and recent molecular analyses. Furthermore, a comprehensive review of this genus is performed, with two species groups proposed based on morphological differences and phylogenetic relationships.

Hyaluronan-modified superparamagnetic iron oxide nanoparticles for bimodal breast cancer imaging and photothermal therapy.

Theranostic nanoparticles with both imaging and therapeutic abilities are highly promising in successful diagnosis and treatment of the most devastating cancers. In this study, the dual-modal imaging and photothermal effect of hyaluronan (HA)-modified superparamagnetic iron oxide nanoparticles (HA-SPIONs), which was developed in a previous study, were investigated for CD44 HA receptor-overexpressing breast cancer in both in vitro and in vivo experiments. Heat is found to be rapidly generated by near-infrared laser range irradiation of HA-SPIONs.

Glycosaminoglycan-targeted iron oxide nanoparticles for magnetic resonance imaging of liver carcinoma.

To develop an efficient probe for targeted magnetic resonance (MR) imaging of liver carcinoma, the surface modification of superparamagnetic iron oxide nanoparticles (SPIONs) was carried out by conjugating a naturally-occurring glycosaminoglycan with specific biological recognition to human hepatocellular liver carcinoma (HepG2) cells. These modified SPIOs have good water dispersibility, superparamagnetic property, cytocompatibility and high magnetic relaxivity for MR imaging. When incubated with HepG2 cells, they demonstrated significant cellular uptake and specific accumulation, as confirmed by Prussian blue staining and confocal microscopy.
