The spread of molecular markers of artemisinin partial resistance and diagnostic evasion in Eritrea: a retrospective molecular epidemiology study.

Background: Eritrea was the first African country to discontinue the use of histidine rich protein 2 (HRP2)-detecting rapid diagnostic tests (RDTs) for malaria diagnosis following reports of a high prevalence of pfhrp2/3-deleted Plasmodium falciparum parasites causing false-negative results in the country. Eritrea was also the first African country to report partial artemisinin resistance due to the P falciparum kelch13 (pfk13) Arg622Ile mutation. We aimed to characterise the spatial distribution of pfk13 mutants and their interactions with pfhrp2/3 deletions in Eritrea and to assess the role of the use of HRP2-detecting RDTs and antimalarial (artesunate-amodiaquine) therapy in the spread of the two variants.

The Association Between Causality Orientation and Internet Gaming Disorder, and the Role of Sensation Seeking, Anxiety, and Depression.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms.

Lipoxin A improves cardiac remodeling and function in diabetes-associated cardiac dysfunction.

Background: Diabetic heart disease may eventually lead to heart failure, a leading cause of mortality in diabetic individuals. The lack of effective treatments for diabetes-induced heart failure may result from a failure to address the underlying pathological processes, including chronic, low-grade inflammation. Previous studies have reported that lipoxin A (LXA), known to promote resolution of inflammation, attenuates diabetes-induced atherosclerosis, but its impact on diabetic hearts has not been sought.

Circulating tumor cells in pancreatic cancer: more than liquid biopsy.

Circulating tumor cells (CTCs) are tumor cells that slough off the primary lesions and extravasate into the bloodstream. By forming CTC clusters and interacting with other circulating cells (platelets, NK cells, macrophage, etc.), CTCs are able to survive in the circulatory system of tumor patients and colonize to metastatic organs.

Characterizing Rock-Breaking Performance of PDC Cutters via Stability Metrics and Energy consumption in FDEM Simulations.

As oil production increasingly transitions from shallow to deep formation, the need for efficient PDC cutters to drill through deep hard rock becomes paramount. Currently, there is a lack of effective methods for optimizing cutter shapes and their cutting parameters. This study addresses this gap by developing a rock-breaking mechanism model for PDC cutters and proposing a Stability Index (SI) based on cutting force variations during the cutting process.

Under Water Superelastic Porous Nanofibrous Sponge for Efficient RNA Separation and Purification.

The results show that when the CS content of the dispersion is 1.

Physiological and transcriptomic profiles reveal key regulatory pathways involved in cold resistance in sunflower seedlings.

During sunflower growth, cold waves often occur and impede plant growth. Therefore, it is crucial to study the underlying mechanism of cold resistance in sunflowers. In this study, physiological analysis revealed that as cold stress increased, the levels of ROS, malondialdehyde, ascorbic acid, and dehydroascorbic acid and the activities of antioxidant enzymes increased.

Biased receptor signalling and intracellular trafficking profiles of structurally distinct formylpeptide receptor 2 agonists.

Background: There is increasing interest in developing FPR2 agonists (compound 43, ACT-389949 and BMS-986235) as potential pro-resolving therapeutics, with ACT-389949 and BMS-986235 having entered phase I clinical development. FPR2 activation leads to diverse downstream outputs. ACT-389949 was observed to cause rapid tachyphylaxis, while BMS-986235 and compound 43 induced cardioprotective effects in preclinical models.

Overlooked interconversion between tetracyclines and their 4-epimers in soil and effects on soil resistome and bacterial community.

With the widespread use of tetracycline antibiotics (TCs) and the application of manure fertilizer in farmland, TCs and their metabolites especially 4-epimers have been heavily detected in agricultural soil. However, existing studies have focused on the residual and environmental behavior of maternal TCs, and few studies have looked at the ecotoxicity of their 4-epimers in soil. In this study, the degradation and interconversion of tetracycline (TC), oxytetracycline (OTC) and their 4-epimers (4-epitetracycline, ETC; 4-epioxytetracycline, OTC) were revealed.
