Abstract Background The SARS-CoV-2 containment strategy has been successful in mainland China prior to the emergence of Omicron. However, in the era of highly transmissible variants, whether it is possible for China to sustain a local containment policy and under what conditions China could transition away from it are of paramount importance at the current stage of the pandemic. Methods We developed a spatially structured, fully stochastic, individual-based SARS-CoV-2 transmission model to evaluate the feasibility...

Abstract Background Exploiting cancer metabolism during nutrient availability holds immense potential for the clinical and therapeutic benefits of hepatocellular carcinoma (HCC) patients. Dietary methionine is a metabolic dependence of cancer development, but how the signal transduction integrates methionine status to achieve the physiological demand of cancer cells remains unknown. Methods Low or high levels of dietary methionine was fed to mouse models with patient-derived xenograft or diethyl-nitrosamine induced liver cancer. RNA sequence and metabolomics were...

Cascaded operations play an important role in traditional electronic computing systems for the realization of advanced strategies. Here, we introduce the idea of cascaded operations into all-optical spatial analog computing. The single function of the first-order operation is difficult to meet the requirements of practical applications in image recognition. The all-optical second-order spatial differentiators are implemented by cascading two first-order differential operation units, and the image edge detection of amplitude and phase objects are demonstrated....

Abstract Background Insecticidal mosquito-proof netting screens could combine the best features of insecticide-treated nets (ITNs) and indoor residual spraying (IRS), the two most important front line vector control interventions in Africa today, and also overcome the most important limitations of these methods. This study engaged members of a rural Tanzanian community in developing and evaluating simple, affordable and scalable procedures for installing readily available screening materials on eave gaps and windows of their own houses,...

Abstract Background Waist circumference (WC), visceral adiposity index (VAI), lipid accumulation product (LAP), and Chinese visceral adiposity index (CVAI) are considered surrogate indicators of abdominal fat deposition, but the longitudinal association of these indices with cardiovascular (CV) events in adults with type 2 diabetes (T2D) remains unclear. Our study aimed to examine the associations between abdominal obesity indices and incident CV events among people with T2D and to compare their predictive performance in risk assessment....

Talaromyces marneffei tends to induce systemic infection in immunocompromised individuals, which is one of the causes of the high mortality. The underlying molecular mechanisms of T.marneffei-induced abnormal liver function are still poorly understood. In this study, we found that T.marneffei-infected patients could develop abnormal liver function, evidenced by reduced albumin and increased levels of aspartate aminotransferase (AST) and AST/alanine aminotransferase (ALT). T. marneffei-infected mice exhibited similar characteristics. In vitro investigations showed that T.marneffei induced the...

Abstract Background: International Confederation of Midwives and World Health Organization recommend core competencies for midwifery educators for effective theory and practical teaching and practice. Deficient curricula and lack of skilled midwifery educators are important factors affecting the quality of graduates from midwifery programmes. The objective of the study was to assess the capacity of university midwifery educators to deliver the updated competency-based curriculum after the capacity strengthening workshop in Kenya. Methods: The study used a...

Since 1982, China’s blue carbon management policies have made significant contributions to blue carbon’s development. Blue carbon is carbon captured and stored by marine ecosystems and it plays an important role in addressing climate change. Analyzing the evolution of blue carbon management policy is necessary to understand its potential to contribute to climate action, and to improve its management and maximize its effectiveness. This paper considers these issues in China. It used content analysis and...

Circular RNAs (circRNAs) are closely associated with cancer development in glioblastoma (GBM), and this study aims to explore the molecular mechanisms of a novel circular RNA circZNF652 in regulating GBM aggressiveness. The present study found that CircZNF652 and SERPINE1 were upregulated, while miR-486-5p was downregulated in GBM tissues and cell lines, and GBM patients with high expression of CircZNF652 and SERPINE1, and patients with low expression of miR-486-5p tended to have a worse prognosis. Further...

A series of new acylthiourea derivatives were synthesized and characterized. The results of preliminary herbicidal activity tests showed that most compounds had good herbicidal activity against Digitaria adscendens and Amaranthus retroflexus, especially for compounds 4b (N-(2-chloro-4-methylsulfonylbenzoyl)-N’-(2-chlorophenyl) thiourea) and 4f (N-(2-chloro-4-methylsulfonylbenzoyl)-N’-(2,3-dichlorophenyl) thiourea). In vivo acetylhydroxylate synthase (AHAS) enzyme activity inhibition tests showed that all compounds had inhibitory activities against the enzyme at a concentration of 100 mg·L−1, with the highest inhibition rate up to 37.05% (compound...

Patients with post-traumatic stress disorder (PTSD) are usually at an increased risk for chronic disorders, such as irritable bowel syndrome (IBS), characterized by hyperalgesia and allodynia, but its subsequent effect on visceral hyperalgesia and the mechanism remain unclear. The present study employed single prolonged stress (SPS), a model of PTSD-pain comorbidity, behavioral evaluation, intrathecal drug delivery, immunohistochemistry, Western blotting, and RT-PCR techniques. When detecting visceral sensitivity, the score of the abdominal withdrawal reflex (AWR) induced...
