Particulate matter (PM) and contaminants attached to PM can increase the risk of respiratory diseases. However, the health risk assessment of chlorinated paraffins (CPs), an emerging pollutant occupying a high proportion of persistent organic pollutants (POPs) in PM, remains scarce. This study aimed to evaluate the association between PM-bound CPs and asthma, along with relative symptoms, in school-aged children and adolescents.

Article Synopsis
  • Chlorinated polyfluorinated ether sulfonic acid (F-53B) has been found in pregnant women and cord blood, raising concerns about its potential risks due to insufficient toxicokinetic data.
  • The study aimed to create a physiologically based pharmacokinetic (PBPK) model using data from pregnant mice who were given F-53B, revealing that the chemical accumulates most in the brain and placenta of fetal mice.
  • The developed mouse model successfully predicted human exposure levels, providing a foundational understanding for better risk assessments, especially for vulnerable groups like pregnant women and their fetuses.

Article Synopsis
  • - The study analyzed data from 1,238 adults to evaluate how different types of PFAS (per- and polyfluoroalkyl substances) affect red blood cell indices, focusing on both isomer and sex differences.
  • - Results indicated that linear (n-) isomers of PFAS showed a stronger positive impact on red blood cell indices in women compared to men, with significant changes in hemoglobin and red blood cell counts.
  • - Findings suggest that when assessing health risks of PFAS, it’s important to consider the specific chemical structures, demographic factors like sex, and their combined effects.

  • The study investigates the link between exposure to chlorinated paraffins (CPs), a type of persistent organic pollutant, and the prevalence of allergic diseases in children and adolescents in the Pearl River Delta region of China.
  • A survey with 131,304 participants highlighted that increased levels of CPs in particulate matter are significantly associated with allergic rhinitis, atopic eczema, and allergic conjunctivitis, showing specific odds ratios for each condition.
  • The research suggests that overweight and obese individuals may be at an even higher risk for these allergic diseases; however, further studies are necessary to confirm these findings and explore the underlying mechanisms.

Background: Medication adherence and the management of adverse drug reactions (ADRs) are crucial to the efficacy of antitumor drugs. A WeChat applet, also known as a "Mini Program," is similar to the app but has marked advantages. The development and use of a WeChat applet makes follow-up convenient for patients with cancer.

The emissions and exposure limits for airborne PM are lacking, with limited scientific data for toxicity. Therefore, we continuously monitored and calculated the number and mass concentrations of airborne PM in December 2017, January 2018 and March 2018 during the high pollution period in Guangzhou. We collected PM from the same period and analyzed their chemical components.

Numerous studies have suggested per-and polyfluoroalkyl substances (PFASs) are related to uric acid levels, but evidence related to PFAS alternatives is limited. Moreover, the effect of the combined exposure to PFASs and their alternatives on uric acid has not been reported. Hence, we conducted a cross-sectional study involving 1312 adults in Guangzhou, China.

Anthropogenic heat has been reported to have significant health impacts, but research on its association with childhood adiposity is still lacking. In this study, we matched the 2008-2012 average anthropogenic heat flux, as simulated by a grid estimation model using inventory methods, with questionnaire and measurement data of 49,938 children randomly recruited from seven cities in Northeast China in 2012. After adjusting for social demographic and behavioral factors, we used generalized linear mixed-effect models to assess the association between anthropogenic heat flux and adiposity among children.

  • Maternal exposure to chlorinated polyfluoroalkyl ether sulfonic acids (Cl-PFESAs) is linked to neurobehavioral issues in the offspring of zebrafish, as shown in this study.
  • The study found that higher concentrations of Cl-PFESAs in zebrafish embryos resulted in decreased swimming speed and distance traveled in the larvae.
  • Additionally, Cl-PFESAs were found to disrupt calcium homeostasis, cause dopaminergic dysfunction, and lead to eye developmental defects, all contributing to behavioral changes in the offspring.

  • A study in Guangzhou, China investigated the impact of per- and polyfluoroalkyl substances (PFASs) exposure on heart function using ECG parameters among 1,229 adults with an average age of 55.1 years.* -
  • Researchers analyzed 13 PFASs and focused on six ECG parameters, finding that exposure to higher levels of PFASs was linked to a decrease in heart rate (HR) and QRS duration, while the PR interval increased.* -
  • For instance, at high exposure levels of 6:2 Cl-PFESA, HR decreased by nearly 7 beats per minute and QRS duration decreased by about 6 milliseconds, while the PR interval increased by over

Background And Objectives: Studies on the effects of airborne particulates of diameter ≤ 1 µm (PM), airborne particulates of diameter ≤ 2.5 µm (PM) and airborne particulates of diameter ranges from 1 to 2.5 µm (PM) on incidence of hyperuricemia are limited.

Chlorinated polyfluorinated ether sulfonates (Cl-PFESAs) are one kind of replacement chemistry for perfluorooctanesulfonate (PFOS). Recent studies have shown that Cl-PFESAs could interfere with thyroid function in animal models. However, epidemiological evidence on the link between Cl-PFESAs and thyroid function remains scarce.

Rosaceae comprises numerous types of economically important fruits, ornamentals, and timber. The lack of plastome characteristics has blocked our understanding of the evolution of plastome and plastid genes of Rosaceae crops. Using comparative genomics and phylogenomics, we analyzed 121 Rosaceae plastomes of 54 taxa from 13 genera, predominantly including (true cherry) and its relatives.

Environmental lead exposure is closely related to the progression of Alzheimer's disease (AD). Our previous study has shown that exposure to lead could result in the cholesterol unbalance and increase amyloid-beta (Aβ) generation in the brain. However, the potential effect of lead exposure on Aβ transportation is poorly reported.

Background: Epidemiological studies on the associations of legacy per- and polyfluoroalkyl substances (PFASs) and glucose homeostasis remain discordant. Understanding of PFAS alternatives is limited, and few studies have reported joint associations of PFASs and PFAS alternatives.

Objectives: To investigate associations of novel PFAS alternatives (chlorinated perfluoroalkyl ether sulfonic acids, Cl-PFESAs and perfluorobutanoic acid, PFBA) and two legacy PFASs (Perfluorooctanoic acid, PFOA and perfluorooctane sulfonate, PFOS) with glucose-homeostasis markers and explore joint associations of 13 legacy and alternative PFASs with the selected outcomes.

Numerous epidemiological studies have investigated the lipid interference effects of legacy PFASs, however, no studies on PFAS alternatives and blood lipids have been published. In this study, we explored the association between Cl-PFESAs, a typical PFASs alternative in China, and blood lipid profiles in 1336 Guangzhou community residents using linear and non-linear regression models. The results showed a deleterious effect of Cl-PFESAs and blood lipids: adjusted estimates (β) for TC, TG, LDL-C and HDL-C per natural log unit increase of 6:2 Cl-PFESA were 0.

Per- and polyfluoroalkyl substances (PFAS) exposure has been linked to diabetes, but evidence on the association of isomers of PFAS with type 2 diabetes (T2D) remains scant. This population based cross-sectional study aimed to investigate associations between serum PFAS isomers, glucose-homeostasis markers and T2D, adjusted for multiple potential confounders. We used data from "Isomers of C8 Health Project in China" from July 2015 to October 2016.

Objective: Patients undergoing carotid endarterectomy (CEA) have a significant possibility of developing postoperative cognitive decline (POCD). POCD after surgery could be result from cerebral hypotension induced by cross-clamping or postoperative hyperperfusion. Optic nerve sheath diameter (ONSD) exhibits an excellent correlation with invasive intracranial pressure monitoring, Here, the authors explored the risk factors of POCD in patients undergoing CEA, paying close attention to ONSD to test the hypothesis that decrease of coronal ONSD was related to the incidence of POCD.
