BACKGROUND: Pain and adhesion are problematic issues after surgery. Lidocaine has analgesics and anti-inflammatory properties, and poloxamer/alginate/CaCl2 (PACM) is a known antiadhesive agent. We hypothesized that the novel combination of lidocaine as chemical barrier and PACM as physical barrier would be beneficial for both postoperative pain and adhesion. The purpose of this study was to investigate the effects of lidocaine-loaded PACM in a rat model of incisional pain. Primary outcome was to evaluate between-group differences for the mechanical withdrawal threshold (MWT) measured by von Frey filament in various concentrations of lidocaine-loaded PACM applied, PACM applied, and sham-operated groups...

The coiled-coil (CC) domain is a very important structural unit of proteins that plays critical roles in various biological functions. The major oligomeric state of CCs is a dimer, which can be either parallel or antiparallel. The orientation of each α-helix in a CC domain is critical for the molecular function of CC-containing proteins, but cannot be determined easily by sequence-based prediction. We developed a biochemical method for assessing differences between parallel and antiparallel CC homodimers and named it ACCORD (Assessment tool for homodimeric Coiled-Coil ORientation Decision)...

We employed modified glass nanocapillaries to investigate interactions between the RNA-binding protein, known as cell carcinoma antigen recognized by T cells-3 (SART3), and the noncoding spliceosome component, U6 small nuclear RNA (snRNA), at the single-molecule level. We functionalized the nanocapillaries with U6 snRNA fragments, which were hybridized to DNA molecules and then covalently attached to the nanocapillary surface. When transported through the modified nanocapillaries, two different SART3-derived constructs, HAT-RRM1-RRM2 and RRM1-RRM2, exhibited resistive ionic current pulses with different dwell times, which represented their different binding affinities to tethered U6 snRNAs...

Hippophae rhamnoides L., also known as sea buckthorn (SBT), possesses a wide range of biological and pharmacological activities. However, the underlying mechanism is largely unknown. The present study examined whether SBT leaf extract could inhibit proliferation and promote apoptosis of rat glioma C6 cells. The results revealed that the treatment with SBT leaf extract inhibited proliferation of rat C6 glioma cells in a dose-dependent manner. SBT-induced reduction of C6 glioma cell proliferation and viability was accompanied by a decrease in production of reactive oxygen species (ROS), which are critical for the proliferation of tumor cells...
