[Inorganic N deposition in the Bayinbuluk alpine grassland of the central Tianshan mountains].

N deposition has increased significantly with economic development and intensive human activities in China and has affected natural ecosystems in remote areas. To evaluate the atmospheric N deposition of the Bayinbuluk alpine grassland of the central Tianshan Mountains, the dry and wet N depositions were monitored from May 2010 to December 2011. Fluxes of HNO3, NH3, NO2, particulate ammonium and nitrate (pNH4+ and pNO3-) averaged at 1.

Gray matter atrophy in progressive supranuclear palsy: meta-analysis of voxel-based morphometry studies.

Voxel-based morphometry (VBM) studies have provided cumulative evidence of gray matter (GM) atrophy in patients with progressive supranuclear palsy (PSP) relative to healthy controls (HC). However, not all findings have been entirely concordant. Herein, we performed a quantitative meta-analysis study in order to consistently quantify GM anomalies in PSP.

Gray matter atrophy in Parkinson's disease with dementia: evidence from meta-analysis of voxel-based morphometry studies.

Voxel-based morphometry (VBM) studies have provided cumulative evidence of gray matter (GM) atrophy in patients with Parkinson's disease with dementia (PDD) relative to healthy controls (HC). However, not all the studies reported entirely consistent findings. A systematic search for VBM studies of PDD patients and HC subjects published in PubMed and Embase databases from January 2000 to June 2012 was conducted.

[Primary lymphoma of breast: a clinicopathologic, immunophenotypic and prognostic study of 21 cases].

Objective: To investigate the clinicopathologic and immunophenotypic features of primary breast lymphoma (PBL) and to discuss the diagnosis of the tumor.

Methods: Twenty-one cases of PBL with follow up data were clinically reviewed. The histologic diagnosis of the tumor was based on the updated WHO Classification of tumors of hematopoietic and lymphoid tissues (2008).

[Cloning and sequencing of alpha, beta globin coding genes in Tibetans living at high altitude].

Aim: To explore the molecular biological mechanism of hemoglobin with high oxygen affinity in Tibetans by determining the sequence of globin cDNA in Tibetans living at high altitude.

Methods: Total RNA was isolated from human bone marrow samples of three Tibetans who live in Qinghai-Tibet plateau. cDNA fragments coding for alpha and beta genes of human hemoglobin were obtained through RT-PCR and were ligated to plasmid pGEM-T easy vectors, and then the ligation liquid were transformed to Escherichia coli and cloned and sequenced.
