Background: Haem is essential but toxic for metazoan organisms. Auxotrophic nematodes can acquire sufficient haem from the environment or their hosts in the meanwhile eliminate or detoxify excessive haem through tightly controlled machinery. In previous work, we reported a role of the unique transporter protein HRG-1 in the haem acquisition and homeostasis of parasitic nematodes. However, little is known about the haem efflux and detoxification via ABC transporters, particularly the multiple drug resistance proteins (MRPs). Results: Here, we further elucidate that a member of the mrp family (mrp-3) is involved in haem efflux and detoxification in a blood-feeding model gastrointestinal parasite, Haemonchus contortus. This gene is haem-responsive and dominantly expressed in the intestine and inner membrane of the hypodermis of this parasite. RNA interference of mrp-3 resulted in a disturbance of genes (e.g. hrg-1, hrg-2 and gst-1) that are known to be involved in haem homeostasis and an increased formation of haemozoin in the treated larvae and lethality in vitro, particularly when exposed to exogenous haem. Notably, the nuclear hormone receptor NHR-14 appears to be associated the regulation of mrp-3 expression for haem homeostasis and detoxification. Gene knockdown of nhr-14 and/or mrp-3 increases the sensitivity of treated larvae to exogenous haem and consequently a high death rate (> 80%). Conclusions: These findings demonstrate that MRP-3 and the associated molecules are essential for haematophagous nematodes, suggesting novel intervention targets for these pathogens in humans and animals.

In recent years, the rapid development of the photovoltaic (PV) industry has resulted in a saturation of research on onshore PV power plant construction. However, current studies on the impact of marine PVs on the marine environment remain limited and scarce. In order to facilitate the implementation of carbon reduction goals and promote the sustainable development of the offshore PV industry, this study analyzes the environmental impact of PV sea-use resources based on spatial information technology in the western part of Gaotang Island. The findings show that the MIKE21FM model provides relatively accurate simulations of tidal flow and tide level in the marine PV area. Flow velocity in the marine PV area exhibits a decreasing trend, with an average decrease ranging from 0.03 to 0.07 m/s. This decrease minimally affects surrounding navigational channels and large-scale flow fields. The resulting siltation is also deemed less significant, with an annual deposition from 0.03 to 0.06 m/a. Moreover, offshore PV construction resulted in a total intertidal biological loss of 123.45 t. The suspension of sediment during cofferdam construction and removal has a potential effect on zooplankton and fishery resources. Overall, it is proposed that careful planning, prudent site selection, and the execution of countermeasures during marine PV construction will combine to minimize the impact on the marine environment.

- Abstract
Narcolepsy type 1 (NT1) is a sleep-wake disorder in which people typically experience excessive daytime sleepiness, cataplexy and other sleep-wake disturbances impairing daily life activities. NT1 symptoms are due to hypocretin deficiency. The cause for the observed hypocretin deficiency remains unclear, even though the most likely hypothesis is that this is due to an auto-immune process. The search for autoantibodies and autoreactive T-cells has not yet produced conclusive evidence for or against the auto-immune hypothesis. Other mechanisms, such as reduced corticotrophin-releasing hormone production in the paraventricular nucleus have recently been suggested. There is no reversive treatment, and the therapeutic approach is symptomatic. Early diagnosis and appropriate NT1 treatment is essential, especially in children to prevent impaired cognitive, emotional and social development. Hypocretin receptor agonists have been designed to replace the attenuated hypocretin signalling. Pre-clinical and clinical trials have shown encouraging initial results. A better understanding of NT1 pathophysiology may contribute to faster diagnosis or treatments, which may cure or prevent it., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Objective: This study investigates the efficacy of DWI combined with intraoperative ultrasound for deep brain glioma treatment, analyzing changes in Karnofsky performance status (KPS) scores and imaging signs. Objectives include elucidating the approach's advantages, addressing knowledge gaps, and contributing insights into its effectiveness for enhancing deep brain glioma management., Methods: In this retrospective study, we analyzed a total of 346 patients with deep brain glioma who underwent surgical treatment at our hospital from July 2015 to January 2022. After applying inclusion and exclusion criteria, 310 patients were selected and categorized into a control group (n = 150) and an observation group (n = 160) based on different auxiliary techniques of surgical treatment. The degree of resection and Karnofsky performance status (KPS) scores were assessed at 1 day preoperatively, 1 week, and 1 month postoperatively for both groups. Additionally, we conducted a comprehensive analysis of DWI and ultrasound imaging signs among patients with different grades of deep brain glioma. The study duration covered the specified period, and statistical analyses were performed to evaluate the outcomes., Results: In our study, the observation group demonstrated significantly improved resection degrees, with a total resection rate of 82.50% compared to the control group's 65.33%. Preoperative Karnofsky performance status scores showed no significant difference between groups (P > .05), but postoperative scores at 1 week and 1 month were significantly higher in the observation group (P < .05). Intraoperative ultrasound and DWI revealed distinct imaging signs differentiating low-grade and high-grade patients. These results highlight the efficacy of DWI combined with intraoperative ultrasound resection in enhancing resection outcomes and influencing postoperative Karnofsky performance status., Conclusions: DWI combined with intraoperative ultrasonic resection in deep brain glioma has a significant effect, with specific imaging signs, which can effectively improve the total resection rate and KPS score, and is worthy of clinical promotion. DWI combined with intraoperative ultrasound has important clinical significance in the resection of deep brain gliomas. The better resection results and improved postoperative Karnofsky performance-status score that we observed suggest a possible benefit in patient outcomes, which could influence treatment strategies. The precise imaging signs identified by this method provide valuable guidance for targeted and effective tumor resection.
