Bursicon is a neuropeptide that regulates cuticle sclerotization （hardening and tanning） in insect via a G-protein coupled receptor. However, the signal transduction pathway downstream of the G-protein coupled receptor is currently not well known. In our recent microarray analysis, we identified a panel of genes regulated by bursicon in Drosophila. One of the genes, Suppressor of Hairless, or Su（H）, has drawn our attention because its product acts down-stream of the bursicon receptor. In the present study, we cloned the Drosophila homolog, mdSu（H）, from the house fly Musca domestica using 3＇ and 5＇ rapid amplification of complementary DNA ends. Real-time polymerase chain reaction analysis revealed that the level ofmdSu（H） transcript is up-regulated by ~3-fold 1 h after recombinant bursicon injection, which correlates well with the cuticle sclerotization process observed in the recombinant bursicon-injected flies. We infer that Su（H） is an essential gene involved in the insect cuticle sclerotization process.

Partridge tea (Mallotus fortians Muell-Arg)， an important and widely consumed substitute tea in Hainan， possessed multi-biological activities. This study investigated the composition and content of phenolics-rich extracts purified from partridge tea， and then explored the effect of partridge tea polyphenol extract (PTE) on glucose and lipid metabolism disorders in type 2 diabetes mellitus (T2DM) mice. The results showed that the dominant components in PTE included rutin (152.78 ± 2.93) mg/g， 3-chlorogenic acid (85.81 ± 3.48) mg/g， caffeic acid (63.78 ± 1.86) mg/g， catechin (12.10 ± 1.41) mg/g， gallic acid (5.24 ± 0.12) mg/g， kaempferitrin， ellagic acid， ferulic acid， caffeic acid methylester， and geraniin. After 6 weeks of PTE intervention， glucose tolerance， insulin resistance， and pancreatic β-cell function in T2DM mice have significantly improved. This improvement was corroborated by an increase in glucagon-like peptide-1 (GLP-1); homeostasis model assessment of β-cell function (HOMA-β)， glycogen， insulin protein expression， and reduction of insulin， glycosylated serum protein (GSP)， homeostasis model assessment-insulin resistance index (HOMA-IR)， glucagon protein expression. The supplementation of PTE also seems to alleviate the inflammatory response， as evidenced by a decrease in endotoxin and inflammatory cytokine levels. Hyperglycemia-induced mitochondrial damage is alleviated by PTE intervention. Hematoxylin-eosin staining (H & E staining) and lipid profile analysis indicate that PTE intervention can help regulate lipid metabolism disorders. In addition， the integration of metabolomics and transcriptomic analysis indicates that PTE intervention could regulate glycolipid metabolism pathways related to T2DM， including insulin， AMPK， bile acid metabolism and glutathione metabolism signaling pathways. More importantly， the validation results from reverse transcription-polymerase chain reaction (RT-PCR) confirmed that the expressions of Scd1， Fasn， Hmgcr， and Slc

Neutral Zn-air batteries(ZABs) have attracted much attention due to the enhanced lifespan and ***, their development is suppressed by the poor catalytic properties of the air-electrocatalysts for oxygen reduction reaction(ORR) and oxygen evolution reaction(OER). Hence,the exploration of highly efficient electrocatalysts for neutral ZABs is critical. Herein, we designed an economical heterostructure of Pt nanoparticle-modified Zn nanoplates(Pt/Zn NPs). Compared with commercial Pt/C electrocatalyst, our Pt/Zn heterostructure exhibits comparable catalytic properties and ultrahigh stability in neutral media. The heterostructure can reduce the dosage of Pt and offer sufficient active sites,resulting in enhanced catalytic properties for ORR/OER in neutral media. When applied to neutral ZABs as air cathode,our heterostructure exhibits a high power density of 45 mW cm^(-2) and excellent stability of more than 850 cycles with negligible decay, making it the most efficient and robust one in neutral electrolyte. This approach opens a new avenue to strategically design catalysts with high activity for neutral ZABs, rendering them potential in portable and wearable electronic devices.
