27-0.67). CONCLUSIONS: The MicroRPM reliably measures MIP and MEP, but its MRPD, MRR, and tau measurements should be considered with caution.”
“While bone-patellar tendon-bone (BPTB) autograft continues to be the “gold standard” and most popular graft choice for primary anterior cruciate ligament (ACL) reconstructions, the use of allograft tissues in ACL reconstruction has steadily increased over the last 2 decades. Advantages of allograft include a lack of donor-site morbidity, unlimited available sizes, shorter operative

times, availability of larger grafts, smaller incisions, improved cosmesis, lower PLX3397 incidence of postoperative arthrofibrosis, faster immediate postoperative recovery, and less postoperative pain. Disadvantages include the potential for disease transmission and prolonged graft healing. Presented in this article are 2 techniques used at the authors’ institution for primary ACL reconstruction with allograft. With the proper indications, knowledge of graft preparation and handling, and technique, allograft tissues in ACL reconstructions can provide the surgeon with clinical results equal to those of autograft reconstructions.”
“A novel amphiphilic thiolated carboxymethyl chitosan was synthesized. It self-assembled into disulfide bond cross-linked nanoparticles in deionized water. The TEM showed that these nanoparticles had a core-shell

structure with an average diameter of 160nm. Dynamic light AZD6094 cell line scattering showed that the nanoparticles were stable in water solution. The particle size changed with pH

EVP4593 inhibitor values and GSH concentrations, and reached a maximum diameter at pH 7.0 and 20 mM GSH respectively, exhibiting an obvious pH/redox responsibility. Methotrexate was encapsulated in nanoparticles reaching encapsulation efficiency as much as 43.4%. Release profiles of methotrexate showed a release rate of 19 wt% in pH 7.4 buffer containing 10 mu M GSH, whereas as high as 93 wt% in pH 5.0 buffer containing 20 mM GSH, indicating that the nanoparticles may be used for tumor-specific drug release. The anticancer activity test in vitro showed that the inhibition rate of methotrexate-loaded nanoparticles against HeLa cells reached 90%. (C) 2014 Elsevier Ltd. All rights reserved,”
“The red coloration of litchi fruit depends on the accumulation of anthocyanins. The anthocyanins level in litchi fruit varies widely among cultivars, developmental stages and environmental stimuli. Previous studies on various plant species demonstrate that anthocyanin biosynthesis is controlled at the transcriptional level. Here, we describe a litchi R2R3-MYB transcription factor gene, LcMYB1, which demonstrates a similar sequence as other known anthocyanin regulators. The transcription levels of the LcMYB1 and anthocyanin biosynthetic genes were investigated in samples with different anthocyanin levels. The expression of LcMYB1 was strongly associated with tissue anthocyanin content.
