Tegmina developed, more exceeding apices of postfemora; basal area slightly broad, tapering; apices obtusely rounded; hind wings longer than tegmina. Procoxa with a spine, ventral surface of all femora without spines, internal and external sides of ventral margin of protibia with 5 spines separately, spines of internal side longer than external side, tibial tympana open on both sides, oval. Mesotibia with 4 spines and 5 spines on internal and external sides of ventral surface, respectively.

Subgenital plate nearly triangular in outline with ϒ-shaped keel; basal half area with a swollen bulge on both lateral sides, apical half area narrow, tongue shaped (Fig. 5B). Colouration. Body light green when alive (yellowish in 100% ethanol). Disc of pronotum with a pair of longitudinal yellowish white stripes. Eyes yellowish brown. Apices of spines of posttibia yellowish brown. Posterior margin of tegmina light brown. Measurements (mm). BL: ♀ 11.0–12.5; PL: ♀ 4.0–4.1; TL: ♀ 18.0–18.3; PFL: 8.5–9.0; OL: 8.0–8.5. Conclusions The complete mitochondrial genome of S. triangula (16,152 bp) displays a highly conserved composition, arrangement and structure compared with the mitochondrial genomes of other Tettigoniids. A T-stretch as a recognition sequence of the mitogenome replication origin and more than one distinct tandem repeat in the CR are common in Tettigoniidae mitogenomes. Both the ML and BI phylogenetic analyses supported the relationships of (Lipotactinae (Hexacentrinae (Conocephalinae (Meconematinae (Bradyporinae, Tettigoniinae))))) in the Tettigoniidae. The female of S. triangula is similar to the male in appearance. The ovipositor is long and moderately upcurved with a ventral valve that has an apical hook. The subgenital plate is nearly triangular in outline with a ϒ-shaped keel; the basal half of the area has a swollen bulge on both lateral sides and the apical half is tongue-shaped.Published as part of Mao, Shaoli, Yuan, Hao, Chang, Huihui, Shi, Fuming & Zhou, Yafu, 2020, Comparative mitochondrial genomics of Shoveliteratura triangula (Orthoptera Tettigoniidae, Meconematinae) and the first description of a female specimen, pp. 507-520 in Zootaxa 4751 (3) on pages 515-516, DOI: 10.11646/zootaxa.4751.3.5, http://zenodo.org/record/371474

Scenario-based simulation of ecosystem service supply and demand in China's Yangtze River Economic Belt
No full textBalancing the supply and demand of ecosystem services is essential for achieving regional sustainable development. A key scientific challenge lies in identifying and improving areas with ecosystem service supply-demand ratio (ESR) imbalances across different spatial scales. Aiming to promote the coordinated development of the economy and ecology in China's Yangtze River Economic Belt (YREB), this study employed a simulated annealing algorithm coupled with the FLUS model to simulate five future land use scenarios for the year 2030. Based on the optimal scenario, ESRs for 2030 were calculated and compared with those in 2010 and 2020. Furthermore, self-organizing mapping (SOM) and Bayesian belief networks (BBNs) were applied to propose optimization pathways from macro and micro perspectives, respectively. The main conclusions are as follows: (1) Over the 30-year period, all four types of ecosystem services exhibited notable changes, with supply states increasing by approximately 4 %–6 % for all services except Carbon Sequestration. In terms of carbon sequestration and soil conservation, Jiangsu and Shanghai remained predominantly in a demand state, with proportions exceeding 90 %. (2) From a macro perspective, CLASS1 areas prioritize economic development, with average ESR values of 0.45, 0.25, 0.15, and 0.30, in contrast to CLASS3 areas, which emphasize ecological conservation. (3) From a micro perspective, the achieved areas for Carbon Sequestration services accounted for the largest share (99.20 %), while the pending optimization area for Water Conservation services accounted for the largest share (92.90 %). To achieve economic and ecological synergistic development in the YREB, differentiated and targeted regulatory strategies should be adopted based on the ESR supply-demand characteristics at multiple spatial scales
pH-triggered surface charge-switchable polymer micelles for the co-delivery of paclitaxel/disulfiram and overcoming multidrug resistance in cancer

To address this issue, we report an intelligent polymer-based drug co-delivery system which could enhance and accelerate cellular uptake and reverse MDR. The nanodrug delivery systems were constructed by encapsulating disulfiram (DSF), a P-glycoprotein (P-gp) inhibitor, into the hydrophobic core of poly(ethylene glycol)-block-poly(l-lysine) (PEG-b-PLL) block copolymer micelles, as well as 2,3-dimethylmaleic anhydride (DMA) and paclitaxel (PTX) were grafted on the side chain of l-lysine simultaneously. The surface charge of the drug-loaded micelles represents as negative in plasma (pH 7.4), which is helpful to prolong the circulation time, and in a weak acid environment of tumor tissue (pH 6.5–6.8) it can be reversed to positive, which is in favor of their entering into the cancer cells. In addition, the carrier could release DSF and PTX successively inside cells. The results of in vitro studies show that, compared to the control group, the DSF and PTX co-loaded micelles with charge reversal exhibits more effective cellular uptake and significantly increased cytotoxicity of PTX to MCF-7/ADR cells which may be due to the inhibitory effect of DSF on the efflux function of P-gp. Accordingly, such a smart pH-sensitive nanosystem, in our opinion, possesses significant potential to achieve combinational drug delivery and overcome drug resistance in cancer therapy.

The inverse along a product and its applications
No full textIn this paper, we study the recently defined notion of the inverse along an element. An existence criterion for the inverse along
a product is given in a ring. As applications, we present the equivalent conditions for the existence and expressions of the inverse along a matrix.The authors are highly grateful to the referee for valuable comments which
led to improvements of the paper. In particular, Remarks 3.2 and 3.4 were
