[Effects of CUMS on excitatory/inhibitory balance of hippocampal and prefrontal cortex pyramidal neurons in anxiety-like mice].

To explore the changes in the excitatory/inhibitory (E/I) balance of pyramidal neurons in prefrontal cortex and hippocampus in mice with anxiety disorder induced by chronic unpredictable mild stress (CUMS). Twenty-four C57/BL6 male mice were randomly divided into control group (CTRL) and model group (CUMS), with 12 mice in each group. The mice in CUMS group were subjected to 21 days of stress, including restraint for 1 h, reversed day/night cycle for 24 h, forced warm water bath for 5 min, water/food deprivation for 24 h, housing in wet sawdust for 18 h, shaking the cage for 30 min, noise for 1 h, and social stress for 10 min.

[Effect of HumicAcid-Heavy Metals on the Nitrogen Removal Performance of ANAMMOX Bacteria and Its Kinetic Analysis].

The effects of two typical heavy metal ions[Cu(Ⅱ) and Ni(Ⅱ)] and humic acid on ANAMMOX nitrogen removal (SAA) were studied through batch experiments, and the kinetic model was analyzed. At the same time, the effects of humic acid-heavy metal on ANAMMOX nitrogen removal were discussed. The results showed that ANAMMOX was promoted when [Cu(Ⅱ)] and [Ni(Ⅱ)] were 3 mg·L, and SAA was increased by 8.

Design and Experiment of Assistive Mechanism for Adjustment of Transrectal Ultrasound Probe.

Transrectal ultrasound prostate biopsy is the most commonly used method for the diagnosis of prostate cancer. During the operation, the doctor needs to manually adjust the ultrasound probe for repeated adjustments, which is difficult to ensure the efficiency, accuracy, and safety of the operation. This paper presents a passive posture adjusting mechanism of transrectal ultrasound probe.

Three-dimensionally porous graphene: A high-performance adsorbent for removal of albumin-bonded bilirubin.

The development of bilirubin adsorbents with high adsorption efficiencies towards albumin-bonded bilirubin is still a considerable challenge. In this work, a three-dimensionally porous graphene (3D-pGR) has been fabricated through a simple carbon dioxide (CO) activation of thermally exfoliated graphite oxide (EGO). Intriguingly, the resultant 3D-pGR material showed hierarchically micro-meso-macroporous structure, high specific surface area of up to 843mg, and large pore volume as high as 2.

Genome-wide mapping of 5-hydroxymethylcytosine in three rice cultivars reveals its preferential localization in transcriptionally silent transposable element genes.

5-Hydroxymethylcytosine (5hmC), a modified form of cytosine that is considered the sixth nucleobase in DNA, has been detected in mammals and is believed to play an important role in gene regulation. In this study, 5hmC modification was detected in rice by employing a dot-blot assay, and its levels was further quantified in DNA from different rice tissues using liquid chromatography-multistage mass spectrometry (LC-MS/MS/MS). The results showed large intertissue variation in 5hmC levels.

[Application of artificial skin combined with external fixator in the treatment of severe open fractures of legs].

Objective: To investigate therapeutic effects of external fixator combined with artificial skin for the treatment of lower limb open fractures.

Methods: From January 2009 to February 2011,56 patients with lower limb open fractures were treated with external fixator and artificial skin following debridement. There were 42 males and 14 females, with a mean age of 43.

VHZ is a novel centrosomal phosphatase associated with cell growth and human primary cancers.

Background: VHZ is a VH1-like (member Z) dual specific protein phosphatase encoded by DUSP23 gene. Some of the dual specific protein phosphatases (DSPs) play an important role in cell cycle control and have shown to be associated with carcinogenesis. Here, the expression of VHZ associated with cell growth and human cancers was investigated.

[Preliminary study on cardiac allograft rejection in mice by Extractum trametes robiniophila murr].

Objective: To study the effect of Extractum trametes robiniophila murr on cardiac allograft rejection in mice.

Methods: All abdominal heterotopic heart transplantation models were divided into three groups as follows: (A) Extractum trametes robiniophila murr group. (B) Rejection group.
