Air pollutants have been linked to some diseases in humans, but their effects on the nervous system were less frequently evaluated. Autism spectrum disorder (ASD) is a group of neurondevelopmental disorders of which the etiology is still unknown. We conducted a study in Taiwan to evaluate the possible associations between prenatal exposure to air pollutants and ASD. From a random sample of one million people in the National Insurance Research Database, we identified all the infants born between 1996 and 2000. We followed them till the end of 2013 and identified cases of ASD. We traced back the mothers’ residence and assessed the exposure to air pollutants using the data obtained from the air quality monitoring database maintained by the government, which included ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matters with diameter less than 10 µm (PM10). Cox proportional hazard models were constructed to evaluate the associations between childhood ASD and exposures to the pollutants in the three trimesters and the whole gestation. We identified a total of 63,376 newborns and included 62,919 as the study cohort. After adjusting for other risk factors, we observed trimester-specific associations between levels of CO, NO2, and PM10 and the risk of childhood ASD. An increase of 1 ppm of CO in the first, second, and third trimester was associated with a hazard ratio (HR) of 1.93 (95% confidence interval [CI]: 1.55–2.39), 1.77 (95%CI: 1.41–2.22), and 1.75 (95%CI: 1.39–2.21), respectively. An increase of 10 ppb in the level of NO2 in the first, second, and third trimester was associated with an HR of 1.39 (95%CI: 1.22–1.58), 1.25 (95%CI: 1.10–1.42), and 1.18 (95%CI: 1.03–1.34), respectively. In conclusion, we found that exposures to CO and NO2 in all three trimesters were associated with increased risks of developing ASD.

Somatic mutations of STK11 or KEAP1 are associated with poor clinical outcomes for advanced non-small-cell lung cancer (aNSCLC) patients receiving immune checkpoint inhibitors (ICIs), chemotherapy, or targeted therapy. Which treatment regimens work better for STK11 or KEAP1 mutated (SKmut) aNSCLC patients is unknown. In this study, the efficacy of atezolizumab versus docetaxel in SKmut aNSCLC was compared. A total of 157 SKmut aNSCLC patients were identified from POPLAR and OAK trials, who were tested by blood-based FoundationOne next-generation sequencing assay. Detailed clinical data and genetic alterations were collected. Two independent cohorts were used for biomarker validation (n = 30 and 20, respectively). Median overall survival was 7.3 months (95% confidence interval [CI], 4.8 to 9.9) in the atezolizumab group versus 5.8 months (95% CI, 4.4 to 7.2) in the docetaxel group (adjusted hazard ratio [HR] for death, 0.70; 95% CI, 0.49 to 0.99; P = .042). Among atezolizumab-treated patients, objective response rate, disease control rate, and durable clinical benefit were higher when blood tumor mutation burden (bTMB) and PD-L1 being higher (biomarker 1, n = 61) or with FAT3 mutation-positive tumors (biomarker 2, n = 83) than otherwise. The interactions for survival between these two biomarkers and treatments were significant, which were further validated in two independent cohorts. In SKmut patients with aNSCLC, atezolizumab was associated with significantly longer overall survival in comparison to docetaxel. Having FAT3 mutation or high TMB and PD-L1 expression potentially predict favorable response in SKmut patients receiving atezolizumab.

The optimum extraction condition of water-soluble asparagus powder through water boiling method is to extract it twice, in the first extraction, 8% is set as the solid-liquid ratio, 15 minutes is set as the soak time and 40 minutes is set as the boiling time; in the second extraction, 10% is set as the solid-liquid ratio, 40 minutes is set as the boiling time. Under this condition, the dry yield rate is 33.98%, and the total active substance yield rate is 10.34% (including flavones yield rate of 1.0%, saponin yield rate of 5.99%, and polysaccharide yield rate of 3.35%). Water-soluble asparagus powder has good removal effects on hydroxyl radicals, superoxide anion free radicals, and DPPH free radicals. The water-soluble asparagus powders made from the raw material in different pick-time have different removal effects on DPPH free radicals, and the asparagus powder made from asparagus picked in August, September, and October is better.The best is to read these instructions and follow the outline of this text.

With the aggravation of power demands, applications of power cables are more extensive. Researchers also start studying power cable fault location to find out a fault point rapidly and accurately, reduce losses effectively, and provide sufficient and continuous power supply. In the paper, by introducing relevant principles of Wavelet Transform, the simulation experiment is conducted. Wavelet decomposition and reconstitution are applied to realize signal filtering. A multi-scale edge detection theory is utilized to realize calculation of cable fault location. The experiment finds that Wavelet Transform is used to calculate power cable fault location with high accurate results. The error is smaller than one sampling distance. Such a method has a larger applied value.
