Article Synopsis
- A study examined the link between solar and geomagnetic activity (SGA) parameters and levels of plasma B-complex vitamins, focusing on 910 participants over a span from 1998 to 2017.
- Researchers found that increases in certain SGA parameters, specifically interplanetary magnetic field (IMF) and sunspot number (SSN), were associated with lower levels of B vitamins and folate, particularly in individuals with higher B-complex supplementation.
- The study is notable for being the first to highlight the negative effects of solar activity on B vitamin and folate levels, suggesting potential health implications during times of heightened solar activity.
Article Synopsis
- The study examined the impact of long-term exposure to fine particulate matter (PM), nitrogen dioxide (NO), warm-season ozone, and particle radioactivity (PR) on lung cancer incidence among Medicare beneficiaries aged 65 and older in the US from 2001 to 2016.
- PM and NO were found to significantly increase the risk of lung cancer, with specific hazard ratios indicating a clear link between higher pollution levels and increased incidence, particularly affecting vulnerable groups such as men, older populations, Blacks, and residents in low-income areas.
- This research highlights the need for further exploration of the combined effects of air pollutants and recognizes disparities related to different demographic and socioeconomic factors.
Unlabelled: Epidemiologic evidence on the relationships between air pollution and the risks of primary cancers other than lung cancer remained largely lacking. We aimed to examine associations of 10-year exposures to fine particulate matter (PM) and nitrogen dioxide (NO) with risks of breast, prostate, colorectal, and endometrial cancers.
Methods: For each cancer, we constructed a separate cohort among the national Medicare beneficiaries during 2000 to 2016.
Purpose: Design and evaluate a knowledge-based model using commercially available artificial intelligence tools for automated treatment planning to efficiently generate clinically acceptable hippocampal avoidance prophylactic cranial irradiation (HA-PCI) plans in patients with small-cell lung cancer.
Materials And Methods: Data from 44 patients with different grades of head flexion (range 45°) were used as the training datasets. A Rapid Plan knowledge-based planning (KB) routine was applied for a prescription of 25 Gy in 10 fractions using two volumetric modulated arc therapy (VMAT) arcs.
Poly- and perfluoroalkyl substances (PFASs) have attracted mounting attention due to their potential harmful effects and degradation-resistant property. This study continuously monitored the concentration of PFASs for four seasons in two years in the northwest of Tai Lake Basin. The occurrence, spatiotemporal distribution, seasonal and annual variation, and source apportionment of 13 PFASs were investigated in 60 surface water sampling sites and 33 emission sources.

In this regard, a rapid, sensitive, and robust method was developed for quantitation of 168 pharmaceuticals and pharmaceutical metabolites using solid-phase extraction (SPE) and liquid chromatography with tandem mass spectrometry. The extraction protocol and instrumental efficiency were specifically addressed to increase analytical workload and throughput.
