Functional magnetic resonance imaging studies of acupuncture at ST36: a coordinate-based meta-analysis.

Background: Functional magnetic resonance imaging (fMRI) has been widely used to investigate the brain effect of acupuncture point Stomach 36 (ST36, Zusanli). However, inconsistent results have hindered our understanding of the neural mechanisms of acupuncture at ST36.

Objective: To perform a meta-analysis of fMRI studies on acupuncture at ST36 to assess the brain atlas of acupuncture at ST36 from available studies.

Structural and functional improvement of amygdala sub-regions in postpartum depression after acupuncture.

Objective: This study aimed to analyze the changes in structure and function in amygdala sub-regions in patients with postpartum depression (PPD) before and after acupuncture.

Methods: A total of 52 patients with PPD (All-PPD group) were included in this trial, 22 of which completed 8 weeks of acupuncture treatment (Acu-PPD group). An age-matched control group of 24 healthy postpartum women (HPW) from the hospital and community were also included.

Consistent functional abnormalities in patients with postpartum depression.

Postpartum depression (PPD) is a common public health concern. A wide range of functional abnormalities in various brain regions have been reported in fMRI studies on PPD, however, a consistent functional changing pattern is still lacking. Herein, we obtained functional Magnetic Resonance Imaging (fMRI) data from 52 patients with PPD and 24 healthy postpartum women (HPW).

Complete mechanochemical defluorination of perfluorooctanoic acid using AlO and Al powders through matching electron-mediated reduction with decarboxylation.

This work reports a mechanochemical (MC) method for complete defluorination of perfluorooctanoic acid (PFOA) by using Al and AlO as milling agents. Both the Al/AlO molar ratio ( [Formula: see text] ) and the pre-thermal treatment of AlO strongly influenced the defluorination of PFOA. When commercial γ-AlO was pre-treated at 1200 °C, the use of Al and heat-treated γ-AlO with [Formula: see text] of 1: 1 led to PFOA defluorination of 100% after ball milling for 26 min at 350 rpm, being much higher than those (8.

Complete Defluorination and Mineralization of Perfluorooctanoic Acid by a Mechanochemical Method Using Alumina and Persulfate.

Perfluorooctanoic acid (PFOA) is a persistent organic pollutant that has received concerns worldwide due to its extreme resistance to conventional degradation. A mechanochemical (MC) method was developed for complete degradation of PFOA by using alumina (AlO) and potassium persulfate (PS) as comilling agents. After ball milling for 2 h, the MC treatment using AlO or PS caused conversion of PFOA to either 1-H-1-perfluoroheptene or dimers with a defluorination efficiency lower than 20%, but that using both AlO and PS caused degradation of PFOA with a defluorination of 100% and a mineralization of 98%.

Roles of intrinsic Mn sites and lattice oxygen in mechanochemical debromination and mineralization of decabromodiphenyl ether with manganese dioxide.

Commercial β-MnO with a chemical formula of approximate MnMnO was used for mechanochemical (MC) oxidative degradation of decabromodiphenyl ether (BDE209). The ball milling process initiated the degradation of BDE209 on β-MnO, yielding a nearly complete degradation and debromination of BDE209 within 2 h. The use of β-MnO exhibited much higher MC debromination efficiency than that by using birnessite (δ-MnO, 40.
