“…The degradation of ecosystem services exacerbates soil erosion and desertification [65,66], seriously affects food safety, and directly threatens regional ecological security [67,68]. Furthermore, as the water source for the middle route of the S-NWDP, the ecological degradation of the UHRB will reduce soil retention and result in water quality deterioration for the middle and downstream reaches of the UHRB and the beneficiaries of the middle line of the S-NWDP [28,33]. In order to ensure that water quality will be maintained for the middle line of the S-NWDP, the cost of water purification and infrastructure may increase in the future.…”

“…Additionally, changes in ESs and their inter-relationships potentially impact built infrastructure such that key regulating ES changes under climate change scenarios should be considered as part of infrastructure investment planning. The South-to-North Water Diversion Project (S-NWDP) is the world's largest water transfer project, transferring an average of 9.5 billion m 3 yr −1 of water from the Hanjiang River to supply 53.1 million people in Northern China [28,29]. The upper Hanjiang River Basin (UHRB) is the core water source area of the middle route of the S-NWDP, and the ecological health of the basin directly affects the quality and quantity of the water being transferred [30].…”

Climate change can have critical impacts on ecosystem services (ESs) and their inter-relationships, especially for water-related services. However, there has been little work done on characterizing the current and future changes in these services and their inter-relationships under a changing climate. Based on the revised universal soil loss equation (RUSLE), the soil conservation service curve number model (SCS-CN), and the improved stochastic weather-generator-based statistical downscaled global climate models (GCMs), we examined two important water-related services, namely, the soil conservation (SC) service and the flood mitigation (FM) service, and their inter-relationship under baseline and future climate scenarios (Representative Concentration Pathways (RCPs) 4.5 and 8.5). We took the Upper Hanjiang River Basin (UHRB), which is the core water source area of the China’s South-to-North Water Diversion Project (S–NWDP), as an illustration. The findings revealed that (1) the SC and FM services will both decrease under the two climate scenarios examined; (2) the SC and FM services showed a significant synergistic inter-relationship and the synergy will be improved by 16.48% and 2.95% under RCP 4.5 and RCP 8.5, respectively, which provides an opportunity for management optimization; (3) the ecological degradation in the UHRB will likely have serious consequences for the middle and lower reaches of the Hanjiang river basin, and therefore impact the actual economic benefits of the S–NWDP. This study points to the necessity for understanding the dynamic changes and inter-relationships of ecosystem services under future climate change and provides information regarding the consequences of climate change, which is useful for policy and infrastructure investment.

“…The orthotopic pancreatic cancer model was prepared by injecting PANC‐1 cells into the pancreas of 8‐week‐old male athymic nude mice (Charles River) using an established surgical method. [ 57,58 ] Mice were anesthetized by isofluorane (5% with O 2 ) during the surgery. Incision was made on the left flank of the abdominal region where the pancreas was typically located, behind the middle of the spleen.…”

A Rationally Designed ICAM1 Antibody Drug Conjugate for Pancreatic Cancer

et al. 2020

Outcomes for pancreatic cancer (PC) patients remain strikingly poor with a 5‐year survival of less than 8% due to the lack of effective treatment modalities. Here, a novel precision medicine approach for PC treatment is developed, which is composed of a rationally designed tumor‐targeting ICAM1 antibody‐drug conjugate (ADC) with optimized chemical linker and cytotoxic payload, complemented with a magnetic resonance imaging (MRI)‐based molecular imaging approach to noninvasively evaluate the efficiency of ICAM1 ADC therapy. It is shown that ICAM1 is differentially overexpressed on the surface of human PC cells with restricted expression in normal tissues, enabling ICAM1 antibody to selectively recognize and target PC tumors in vivo. It is further demonstrated that the developed ICAM1 ADC induces potent and durable tumor regression in an orthotopic PC mouse model. To build a precision medicine, an MRI‐based molecular imaging approach is developed that noninvasively maps the tumoral ICAM1 expression that can be potentially used to identify ICAM1‐overexpressing PC patients. Collectively, this study establishes a strong foundation for the development of a promising ADC to address the critical need in the PC patient care.

“…The Sugan Lake Wetland (Figure 1) is the tail wetland in the basin, located in the western part of the basin and including the large and small Sugan Lake and its surrounding marshes and meadows. This wetland is approximately fan-shaped and has an area of approximately 1492 km 2 . There are many kinds of vegetation in the wetland (which is an important vegetation distribution area in the Sugan Lake Basin), including Phragmites communis, Achnatherum splendens, Blysmus sinocompressus, Artemisia frigida Willd, Poa annua L., Carex tristachya, and Agropyron cristatum.…”

“…Water resources are the basis for maintaining the ecological environment and social development, and water quality is the key to protecting the ecological environment and ensuring social and economic sustainability [1,2]. As one of the most important water sources of terrestrial ecosystems, groundwater has profoundly influenced the growth and distribution of groundwater-dependent plants [3,4].…”

Groundwater chemistry has an important impact on the vegetation distribution in inland areas. An in-depth understanding of the impact of groundwater chemistry on vegetation can help in developing an effective management strategy to protect the inland ecosystem. The aim of this study was to identify the influence of groundwater chemicals on species diversity and the distribution characteristics of wetland plants at multiple scales based on the groundwater chemical data from 15 sampling points and the distribution data of 13 plants in the Sugan Lake Wetland in 2016. The results show that the groundwater of the Sugan Lake Wetland is weakly alkaline, with high salinity and hardness; the water chemical type is Na-SO4-Cl; the concentration of the major water chemical parameters is significantly different and is the highest in the northwest, followed by the southwest, and is the lowest in the east; with an increase in the groundwater depth, the concentration of major water chemical parameters first showed an increasing trend followed by a decreasing trend; Artemisia frigida Willd, Poa annua L. and Triglochin maritimum L. were adapted to the environment with a higher ion concentration of the groundwater, and their salt resistance was the strongest; Blysmus sinocompressus and Polygonum are more adapted to the environment with lower salinity and hardness of groundwater; Thermopsis lanceolata has stronger adaptability to the ion concentration, salinity, and hardness of groundwater; other plants are adapted to environments where the ion concentration, salinity, and hardness of the groundwater are moderate.
