Article Synopsis
- The study focuses on optimizing fermentation conditions and medium ingredients for the Y1402 strain, which is important for producing enzymes and flavor substances in traditional fermented foods.
- It identified the best components for the fermentation medium, including glucose and peptone, resulting in a significant increase in bacterial colony count after just three days.
- The optimal fermentation conditions were established to enhance production efficiency, achieving a near 31-fold increase in colony count, which has implications for industrial-scale applications.
Polysaccharides extracted from (AAPS) have various physiological effects. In this study, we used the naturally aging and D-galactose-induced aging mice as animal models to study the anti-aging effects of AAPS via the alleviation of oxidative stress and regulation of gut microbiota. Results showed that AAPS could significantly prolong lifespan and alleviate oxidative stress induced by HO of .

April 2015
Article Synopsis
- The study focuses on creating and testing a new flexible flat cable antenna (FFCA) for MRI scans of the knee at various bending angles.
- The FFCA demonstrated a high signal-to-noise ratio (SNR) in both in vitro and in vivo tests, outperforming an eight-channel knee coil in terms of SNR and image coverage.
- The FFCA successfully produced clear knee images at different flexion angles, showcasing benefits like simplicity, low cost, and improved image quality for MRI of the knee joint.
[Feasibility of using intravascular loopless monopole antenna to image atherosclerotic plaque in a porcine model with 3.0 T magnetic resonance imaging].

May 2013
Article Synopsis
- The study aimed to evaluate the effectiveness of a new type of antenna, called intravascular loopless monopole antenna (ILMA), in imaging atherosclerotic plaque using 3.0T MRI in a pig model.
- Researchers created atherosclerosis in 6 pigs through a high fat diet and surgical injury, then performed MR imaging and compared the results with pathological findings after the pigs were euthanized.
- The results indicated high accuracy in measuring vessel dimensions and plaque burden between MRI and pathology, with the highest sensitivity (100%) in detecting calcified plaques, alongside solid overall agreement for other plaque types.
An intravascular loopless monopole antenna for vessel wall MR imaging at 3.0 T.
Magn Reson Imaging
January 2013
Article Synopsis
- The study developed a new type of intravascular antenna called the intravascular loopless monopole antenna (ILMA) for improved imaging of small blood vessel walls.
- The ILMA design features a thin, unshielded nitinol guide wire coated with polyurethane and an aluminum tuning/matching box, making it more efficient than previous coaxial cable designs.
- Testing showed that the ILMA could achieve high-resolution imaging capabilities both in lab tests and in living subjects, suggesting its potential for advancing MR diagnostics and treatments for cardiovascular diseases.
