Diagnosis of children with attention-deficit/hyperactivity disorder (ADHD) comorbid autistic traits (ATs) by applying quantitative magnetic resonance imaging techniques.

Shilong Tang, Ling He et 5 al.

Nov 17, 2022 in Frontiers in psychiatry
To explore the feasibility of applying quantitative magnetic resonance imaging techniques for the diagnosis of children with attention-deficit/hyperactivity disorder (ADHD) comorbid autistic traits (ATs). A prospective study was performed by selecting 56 children aged 4-5 years with ADHD-ATs as the study group and 53 sex- and age-matched children with ADHD without ATs as the control group. All chi...

Application of Quantitative Susceptibility Mapping in the Assessment of Iron Content in Brain Regions in Normal Children.

Shilong Tang, Ling He et 4 al.

Mar 25, 2022 in Current medical imaging
We evaluated brain iron content in a healthy pediatric population using quantitative susceptibility mapping (QSM). From June 2018 to December 2019, healthy subjects aged 2-18 years old (200 males, 200 females) with no anatomical abnormalities were assessed. All of the children underwent 3D T1 anatomical MRIs in addition to the sequence scans of enhanced T2 star-weighted angiography (ESWAN). The ES...

Application of Quantitative Magnetic Resonance Imaging in the Diagnosis of Autism in Children.

Shilong Tang, Ling He et 6 al.

May 12, 2022 in Frontiers in medicine
To explore the application of quantitative magnetic resonance imaging in the diagnosis of autism in children. Sixty autistic children aged 2-3 years and 60 age- and sex-matched healthy children participated in the study. All the children were scanned using head MRI conventional sequences, 3D-T1, diffusion kurtosis imaging (DKI), enhanced T2*- weighted magnetic resonance angiography (ESWAN) and 3D-...

Application of Three-Dimensional Pseudocontinuous Arterial Spin Labeling Perfusion Imaging in the Brains of Children With Autism.

Shilong Tang, Ling He et 6 al.

Feb 23, 2022 in Frontiers in neurology
To explore the application of three-dimensional pseudocontinuous arterial spin labeling (3D-PCASL) perfusion imaging in the brains of children with autism and to understand the characteristics of cerebral blood perfusion in children with autism. A total of 320 children with autism (160 men and 160 women) aged between 2 and 18 years and 320 age- and sex-matched healthy children participated in the ...

Quantitative susceptibility mapping shows lower brain iron content in children with attention-deficit hyperactivity disorder.

Shilong Tang, Ling He et 6 al.

Feb 2, 2022 in Human brain mapping
This study found that the decreased iron content in some brain regions of children with ADHD. This study found that the globus pallidus, caudate nucleus, hippocampus, and putamen could distinguish children with ADHD (AUC > 0.5, p .05). The volume of frontal lobe and hippocampus of children with ADHD was lower than that of healthy children (p 0.5, p < .05). Quantitative susceptibility mapping showe...

Deep geologic process of Machangqing Cu-Mo-Au ore deposit

Jixiong Xiao, Xianfan Liu

Jan 1, 2011 in 2011 International Conference on Remote Sensing, Environment and Transportation Engineering
Machangqing Cu-Mo-Au ore deposit is a typical deposit related to the Himalayan Epoch alkaline-rich porphyries along the Jinshajiang- Ailaoshan deep fault. From the rock body→ contanct zone→ wall-rocks, mineralization zones can be divided into Mo→Cu→Au, and the mineralization temperature cooled down as high→high-medium→medium-low→low. By the way of the geological age`s studies, we discovered that a...

Element geochemistry and geologic significance of the basanite and its xenoliths in the Maguan Area, Yunnan Province

Chunhui Li, Xianfan Liu

Jan 1, 2011 in 2011 International Conference on Remote Sensing, Environment and Transportation Engineering
There are kinds of xenoliths in volcanic breccia rocks at Maguan Area, Yunnan Province. Systemically petrological and geochemical studies of the host rocks and their xenoliths show that they can be classified into three groups, basanlte and ultrapotassic rocks as cements of volcanic breccia rocks, and spinel mantle peridotite which can be further divided into two groups. The one is primitive perid...

Petrogenesis and geodynamic setting of granitoids at Machangqing Cu–Mo (Au) deposit, western Yangtze craton, southwestern China: constraints from zircon U–Pb and molybdenite Re–Os geochronology, Lu–Hf isotopes, and geochemistry

Mimi Yang, Wenjing Duan et 5 al.

Jan 1, 2020 in Canadian Journal of Earth Sciences
The Machangqing Cu–Mo (Au) deposit is located in the central part of the Jinshajiang – Red River belt in the Sanjiang orogen, which lies across the Qiangtang terrane and western Yangtze craton, sou...

Geochemistry and U-Pb ages of the diabases from the Luoji area, western Yunnan, China: implications for the timing of initial rifting of the Ganzi-Litang Ocean

Chan Wang, Fufeng Zhao et 5 al.

Jan 1, 2019 in Geologia Croatica
Detailed geochemical and U-Pb studies of two diabases (Luoji and Cuiyi) from the Luoji area have been undertaken. The diabases are high-K calc-alkaline and belonging to the tholeiitic series, enriched in large ion lithophile elements, Ti, Zr and light rare earth elements, and depleted in high field strength elements. These characteristics are different from the oceanic island basalt but highly con...

Actual traces of mantle fluid from alkalic-rich porphyry and deep xenoliths in Liuhe, Yunnan, and its implication to geology

Yating Chu, Xianfan Liu

Jan 1, 2011 in 2011 International Conference on Remote Sensing, Environment and Transportation Engineering
There are quite a few mantle xenoliths and one special Fe-rich melt xenolith in aegirine syenite porphyry, Liuhe, Yunnan province. Petrographic research shows that black opaque material that is Fe-rich glass, which are widely distribute reticulate along intergranular cracks of minerals, crystals fissues and cleavage in association with metasomatic alteration in the mafic-ultramafic xenoliths and t...
