Source identification and toxicity apportionment of polycyclic aromatic hydrocarbons in surface soils in Beijing and Tianjin using a PMF-TEQ method.

Beijing and Tianjin are two of the largest cities in northern China with high population densities and highly developed manufacturing industries. In the past decade, some authors have reported their PAH concentrations in surface soils, identified their sources and quantitatively reported their health risks. However, the contributions of different PAH sources to their toxicity have not been reported thus far.

Prevalence of Adverse Effects Associated With Transcranial Magnetic Stimulation for Autism Spectrum Disorder: A Systematic Review and Meta-Analysis.

Background: A growing number of studies have suggested that transcranial magnetic stimulation (TMS) may represent a novel technique with both investigative and therapeutic potential for autism spectrum disorder (ASD). However, a full spectrum of the adverse effects (AEs) of TMS used in ASD has not been specifically and systematically evaluated.

Objective: This systematic review and meta-analysis was to assess the prevalence of AEs related to TMS in ASD and to further explore the potentially related factors on the AEs.

Alteration of gamma-aminobutyric acid in the left dorsolateral prefrontal cortex of individuals with chronic insomnia: a combined transcranial magnetic stimulation-magnetic resonance spectroscopy study.

Objective: To investigate changes in the level of gamma-aminobutyric acid (GABA) in the left dorsolateral prefrontal cortex (DLPFC) of patients with chronic insomnia treated with real repetitive transcranial magnetic stimulation (rTMS) as compared to sham-rTMS, as measured with H-Magnetic Resonance Spectroscopy (H-MRS).

Methods: Forty chronic insomnia participants were randomized to either real or sham rTMS group. The rTMS was administered once per day Continuously for 14 days with the stimulation over the left DLPFC.

Pollution status of PAHs in surface sediments from different marginal seas along China Mainland: A quantitative evaluation on a national scale.

China is one of the largest coastal countries in the world, which have all kinds of marginal systems. Studies have reported the sedimentary Polycyclic aromatic hydrocarbons (PAHs) pollution status, including their concentrations, sources and risks, in localized marginal systems, which showed significant differences. Thus, a comprehensive understanding of their pollution in marginal systems along China Mainland is urgently needed on a national scale.

A randomized controlled trial of mindfulness-based stress reduction for insomnia secondary to cervical cancer: Sleep effects.

Aim: To evaluate the efficacy of mindfulness-based stress reduction on objective and subjective sleep parameters and hypnotic medication use of patients with insomnia secondary to cervical cancer.

Methods: This was a randomized controlled trial enrolled insomnia patient who were caused or worsened by cervical cancer. Seventy patients with insomnia caused or aggravated by cervical cancer were at random divided into either a usual care group or an 8-week mindfulness-based stress reduction group.
