PURPOSE: Some studies have suggested that BAFF and BAFFR are highly expressed in the central nervous system (CNS) and participate in inflammatory and immune associated diseases. However, whether BAFF and BAFFR are involved in the pathogenesis of epilepsy remains unknown. This study aimed to investigate the expression of BAFF and BAFFR proteins in the brains of patients with temporal lobe epilepsy (TLE) and in a pilocarpine-induced rat model of TLE to identify possible roles of the BAFF-BAFFR signaling pathway in epileptogenesis...

We rationally designed a facile two-step approach to synthesize ZnMn2O4@G composite anode material for lithium-ion batteries (LIBs), involving a template-free fabrication of ZnMn2O4 nanorings and subsequent coating of graphene sheets. Notably, it is the first time that ring-like ZnMn2O4 nanostructure is reported. Moreover, our system has been demonstrated to be quite powerful in producing ZnMn2O4 nanorings regardless of the types of Zn and Mn-containging metal salts reactants. The well-known inside-out Ostwald ripening process is tentatively proposed to clarify the formation mechanism of the hollow nanorings...

The PIN-FORMED (PIN) protein, the most important polar auxin transporter, plays a critical role in the distribution of auxin and controls multiple biological processes. However, characterizations and functions of this gene family have not been identified in cotton. Here, we identified the PIN family in Gossypium hirsutum, Gossypium arboreum, and Gossypium raimondii. This gene family was divided into seven subgroups. A chromosomal distribution analysis showed that GhPIN genes were evenly distributed in eight chromosomes and that the whole genome and dispersed duplications were the main duplication events for GhPIN expansion...

A self-templated strategy is developed to fabricate hierarchical TiO2 /SnO2 hollow spheres coated with graphitized carbon (HTSO/GC-HSs) by combined sol-gel processes with hydrothermal treatment and calcination. The as-prepared mesoporous HTSO/GC-HSs present an approximate yolk-double-shell structure, with high specific area and small nanocrystals of TiO2 and SnO2 , and thus exhibit superior electrochemical reactivity and stability when used as anode materials for Li-ion batteries. A high reversible specific capacity of about 310 mAh g(-1) at a high current density of 5 A g(-1) can be achieved over 500 cycles indicating very good cycle stability and rate performance...

Arctigenin (ARG) is famous in its abundant pharmacological activity. However, many researches in it entered the bottleneck period because of its poor water solubility. The derivatives of ARG have been synthesised with five amino acids which have t-Butyloxy carbonyl (BOC) as a protective group. We examined the effects of removing BOC. The results showed that the amino acid derivatives without protective group have better water solubility and nitrite-clearing ability than ARG. Based on these results, ARG6' and ARG9' were selected at a dosage of 40 mg/kg to evaluate their antitumour activity...

Direct SERS-based quantification of inorganic metal species has been a problem, because they have a small Raman cross-section or even no vibrational mode. Here, we report a new strategy for SERS-based quantification of such metal species, as exemplified by inorganic mercury (Hg(II)) in waters. Step-by-step design and synthesis from azathioethers [3, 9-dithia-6-monoazaundecane (DMA) and 3,6,12,15-tetrathia-9-monoazaheptadecane (TTM)] to an azathiacrown [7-aza-1,4,10,13-tetrathiacyclohexadecane (NS4)] demonstrate an improved S-pulling effect and size-fit specificity towards Hg(II) to form Hg-S bonds...
