Exploring the effects of ant nests on soil CH emissions in the secondary tropical forests is of great scientific significance to understand the contribution of soil faunal activities to greenhouse gas emissions. With static chamber-gas chromatography method, we measured the dry-wet seasonal dynamics of CH emissions from ant nests and control soils in the secondary forest of communities in Xishuangbanna. We also examined the linkages of ant-mediated changes in functional microbial diversity and soil physicochemical properties with CH emissions.

Effect of long-term exercise training on static postural control in older adults: a cross-sectional study.

We examined the effects of long-term exercise on age-related decline in static balance control through centre-of-pressure (CoP) measurements of four groups of participants: older controls, younger controls, older Tai Chi exercisers and older joggers. The participants stood quietly in a tandem stance on a force platform for 30 s with eyes open (EO) and eyes closed (EC). The older controls showed remarkably larger CoP and EC/EO ratios than younger controls and older Tai Chi exercisers.

[Effects of ant colonization on spatiotemporal variation of organic carbon mineralization in Xishuangbanna tropical forest soils].

[Effects of ant nesting on the spatiotemporal dynamics of soil easily oxidized organic carbon in Xishuangbanna tropical forests, China].

Ant nesting can form microhabitat and soil nutrient condition in their nests that is diffe-rent from the surrounding environment, thus having a crucial effect on the variation of soil easily oxidized organic carbon (EOC). In this study, the Mallotus paniculatus communities in Menglun Tropical Botanical Garden of Xishuangbanna, Chinese Academy of Sciences was taken as the research object. We compared the spatiotemporal distribution of soil EOC in ant nests and the refe-rence soils, and analyzed the relationship of the variation in soil EOC to the changes in soil physicochemical properties.

Acupoint Specificity on Colorectal Hypersensitivity Alleviated by Acupuncture and the Correlation with the Brain-Gut Axis.

This project was focused on the study of the effect of the different acupoints on visceral hypersensitivity and the correlation with the brain-gut axis. By using a mouse model of zymosan-induced colorectal hypersensitivity, and observing the response of hypersensitivity model to colorectal distension stimulation in acupuncture at different acupoints, we selected the specific acupoints. With immunohistochemical staining method, we observed c-fos expression, distribution and changes after acupuncture on sensory pathway, including colorectum, spinal dorsal horn and different regions of brain center in the model with colorectal distension stimulation, and evaluated the acupuncture effect on brain-gut axis.

Acupoint specificity on acupuncture regulation of hypothalamic- pituitary-adrenal cortex axis function.

Background: The hypothalamus is an essential part of the brain that responds to a variety of signaling including stressful stimulations and acupuncture signals. It is also the key element of the hypothalamic-pituitary-adrenal cortex axis(HPAA). The effect of acupuncture is transmitted into the brain from the distance sensory receptor around the acupoints via peripheral nerves and body fluid.

Acupuncture Relieves the Excessive Excitation of Hypothalamic-Pituitary-Adrenal Cortex Axis Function and Correlates with the Regulatory Mechanism of GR, CRH, and ACTHR.

It had been indicated in the previous studies that acupuncture relieved the excessive excitation of hypothalamic-pituitary-adrenal cortex axis (HPAA) function induced by stress stimulation. But the changes in glucocorticoid receptor (GR) induced by acupuncture have not been detected clearly. The objective of the study was to observe the impacts of acupuncture on the protein expressions of corticotrophin releasing hormone (CRH), adrenocorticotropic hormone receptor (ACTHR), and GR under the physiological and stress states.

Effect of optogenetic stimulus on the proliferation and cell cycle progression of neural stem cells.

Modulation of stem cell proliferation is a crucial aspect of neural developmental biology and regenerative medicine. To investigate the effect of optical stimulation on neural stem cell proliferation, cells transduced with channelrhodopsin-2 (ChR2) were used to analyze changes in cell proliferation and cell cycle distribution after light stimulation. Blue light significantly inhibited cell proliferation and affected the cell cycle, which increased the percentage of cells in G1 phase and reduced the percentage in S phase.

The lunge is the most fundamental skill in badminton competitions. Fifteen university-level male badminton players performed lunge maneuvers in four directions, namely, right-forward, left-forward, right-backward, and left-backward, while wearing two different brands of badminton shoes. The test compared the kinetics of badminton shoes in performing typical lunge maneuvers.

Inhibition of HCN channels within the periaqueductal gray attenuates neuropathic pain in rats.

Peripheral and spinal hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels play important roles in neuropathic pain by regulating neuronal excitability. However, the participation of HCN channels in the ventral-lateral periaqueductal gray (vlPAG) during neuropathic pain states has not been clarified. To investigate the role of vlPAG HCN channels in neuropathic pain, the authors developed a chronic constriction injury (CCI) model.

The role of HCN channels within the periaqueductal gray in neuropathic pain.

Peripheral and spinal hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play a key role in neuropathic pain by regulating neuronal excitability. HCN channels are expressed in the ventral-lateral periaqueductal gray (vlPAG), a region that is important for pain modulation. However, the role of vlPAG HCN channels in neuropathic pain remains poorly understood.
