Acupuncture for persistent atrial fibrillation after catheter ablation: study protocol for a pilot randomized controlled trial.

Background: Atrial fibrillation (AF) is a common arrhythmia, which is closely related to cardiovascular morbidity and mortality. Although acupuncture is used in the treatment of AF, the evidence is insufficient. The objective of this pilot trial is to evaluate the feasibility, preliminary efficacy, and safety of acupuncture in reducing AF burden for persistent AF after catheter ablation (CA).

Development of a colloidal gold immunochromatographic strip for rapid detection of Streptococcus agalactiae in tilapia.

A colloidal gold immunochromatographic strip was developed for rapid detection of Streptococcus agalactiae (S. agalactiae) infection in tilapia. The monoclonal antibodies (mAb) 4C12 and 3A9 were used to target S.

Age-related decrease in constructive activation of Akt/PKB in SAMP10 hippocampus.

Aging is the greatest risk factor for neurodegenerative diseases such as Alzheimer's disease (AD). Age-dependent alterations of cell signaling play an important role in the onset of AD. The serine/threonine kinase Akt is a critical cell signaling to neuronal survival.

[Intraspecific DNA sequence polymorphism and genetic markers in the mitochondrial CO I gene from three populations of Macrobrachium rosenbergii].

The mitochondrial COI gene was PCR amplified and sequenced from 17 samples obtained from three populations of Macrobrachium rosenbergii (F1 of the Burma wildtype population, Jiangsu cultured population and F2 of the Guangxi breeding population). A 498-bp long partial gene segment was acquired and used to study the genetic diversity among the three populations. Results indicated that the COI gene locus was relatively more polymorphic in the F1 of Burma wildtype population, while the polymorphism in Jiangsu cultured population and Guangxi breeding population were very poor.
