[Comparison of the clinical efficacy on chronic abdominal wall pain between trigger-point electroacupuncture and transversus abdominis plane block].

Objectives: To compare the clinical efficacy between trigger-point (TrP) electroacupuncture and transversus abdominis plane (TAP) block in treatment of chronic abdominal wall pain (CAWP).

Methods: A total of 62 CAWP patients were randomly divided into a TrP electroacupuncture group (31 cases, 1 case dropped off) and a TAP block group (31 cases, 1 case dropped off). Electroacupuncture at trigger points was delivered in the TrP electroacupuncture group, and TAP block was administered under ultrasonic guidance in the TAP block group.

The Positive Effect of Perceived Exercise Benefit and the Negative Effect of Perceived Severity of Disease and Weakness on College Students' Amount of Exercise: The Mediate and Suppressor Role of Physical Fitness Evaluation Self-Efficacy.

The decline in the physical fitness of college students has become a serious social problem worldwide. Therefore, exploring the factors affecting the amount of exercise of college students is of great significance in improving college students' physique. According to the expectation value theory and previous studies, perceived exercise benefit and perceived severity of disease and weakness may have positive or negative impact on exercise behavior, and according to the self-efficacy theory, physical evaluation self-efficacy may be the most powerful motivational factors and it play a mediating role between other factors and exercise behavior.

Lineage-Specific Rewiring of Core Pathways Predating Innovation of Legume Nodules Shapes Symbiotic Efficiency.

The interkingdom coevolution innovated the rhizobium-legume symbiosis. The application of this nitrogen-fixing system in sustainable agriculture is usually impeded by incompatible interactions between partners. However, the progressive evolution of rhizobium-legume compatibility remains elusive.

Conserved Composition of Nod Factors and Exopolysaccharides Produced by Different Phylogenetic Lineage Strains Nodulating Soybean.

The structural variation of symbiotic signals released by rhizobia determines the specificity of their interaction with legume plants. Previous studies showed that strains from different phylogenetic lineages had different symbiotic performance on certain cultivated soybeans. Whether they released similar or different symbiotic signals remained unclear.

Evidence for Phosphate Starvation of Rhizobia without Terminal Differentiation in Legume Nodules.

Phosphate homeostasis is tightly modulated in all organisms, including bacteria, which harbor both high- and low-affinity transporters acting under conditions of fluctuating phosphate levels. It was thought that nitrogen-fixing rhizobia, named bacteroids, inhabiting root nodules of legumes are not phosphate limited. Here, we show that the high-affinity phosphate transporter PstSCAB, rather than the low-affinity phosphate transporter Pit, is essential for effective nitrogen fixation of Sinorhizobium fredii in soybean nodules.

Nonspecific Symbiosis Between Sophora flavescens and Different Rhizobia.

We explored the genetic basis of the promiscuous symbiosis of Sophora flavescens with diverse rhizobia. To determine the impact of Nod factors (NFs) on the symbiosis of S. flavescens, nodulation-related gene mutants of representative rhizobial strains were generated.

Adaptive evolution of rhizobial symbiotic compatibility mediated by co-evolved insertion sequences.

Mutualism between bacteria and eukaryotes has essential roles in the history of life, but the evolution of their compatibility is poorly understood. Here we show that different Sinorhizobium strains can form either nitrogen-fixing nodules or uninfected pseudonodules on certain cultivated soybeans, while being all effective microsymbionts of some wild soybeans. However, a few well-infected nodules can be found on a commercial soybean using inocula containing a mixed pool of Tn5 insertion mutants derived from an incompatible strain.

Increased annexin A2 and decreased β-catenin in adenomyosis contribute to adenomyosis-associated dysmenorrhea.

Objective: To investigate the expression of annexin A2 (ANXA2) and β-catenin in eutopic and ectopic endometrium, and their relationships with adenomyosis-associated dysmenorrhea.

Methods: From December 2013 to June 2014, ectopic endometrium (n=30) and eutopic endometrium (n=30) of adenomyosis were collected as experimental group, and endometrium (n=30) of uterine myoma as control group from the department of gynecology and obstetrics, the affiliated hospital of Inner Mongolia medical university. The expression of ANXA2 and β-catenin was detected by immunohistochemical S-P method, followed by the Pearson correlations for the correlation analysis of ANXA2 and β-catenin with adenomyosis-associated dysmenorrhea.

Rhizobium hidalgonense sp. nov., a nodule endophytic bacterium of Phaseolus vulgaris in acid soil.

One Gram-negative, aerobic, motile, rod-shaped bacterium, designated as FH14, was isolated from nodules of Phaseolus vulgaris grown in Hidalgo State of Mexico. Results based upon 16S rRNA gene (≥99.8 % similarities to known species), concatenated sequence (recA, atpD and glnII) analysis of three housekeeping genes (≤93.
