[Complex mechanisms of chronic pain in knee osteoarthritis identified by neuroimaging technology].

Chronic pain of knee osteoarthritis (KOA) greatly affects the quality of life and functional activities of patients. It is important to clarify the underlying mechanisms of KOA pain and the analgesic effect of different therapies. Neuroimaging technology has been widely used in the basic and clinical research of pain.

[Effects of manual loading on calcitonin gene-related peptide and nerve growth factor in rats with chronic low back pain].

Objective: To observe the analgesic effect of manipulation loading on chronic low back pain (CLBP) model rats and the expression of inflammatory factors in psoas major muscle tissue, and to explore the improvement of manipulation on local inflammatory microenvironment.

Methods: Thirty two SPF male SD rats weighing 340-360g were randomly divided into blank group, sham operation group, chronic low back pain model group and treatment group, with 8 rats in each group. In the model group, L-L lumbar vertebrae were implanted with external link fixation system (ELFS).

Effect of Fabrication Parameters on the Performance of 0.5 wt.% Graphene Nanoplates-Reinforced Aluminum Composites.

Aluminum composites reinforced by graphene nanoplates(GNP) with a mass fraction of 0.5% (0.5 wt.

[The moss Physcomitrella patens, a new model system for functional genomics].

The potential of moss as a model system to study plant biological process is associated with their relatively simple developmental pattern and the dominance of the haploid gametophyte in the life cycle. The moss Physcomitrella patens exhibits a very high rate of homologous recombination in its nuclear DNA, making gene targeting approaches in this plant as convenient as in yeast or in ES cells of mice. Sharing many biological features with higher plants and having many other advantages, the moss Physcomitrella patens will be an attractive model system for plant biology and functional genome analysis.
