The aim of this study is to test the adhesion of human gingival broblasts (HGFs) and epithelial cells (HGEs) to titanium surfaceby RGD grafting for dental implant, and to obtain an eective perimucosal seal of soft tissue to the implant. RGD peptides werecovalently attached to the titanium surface by CDI activation method to improve the adhesion of gingival cells to the titanium den-tal implants. HGFs and HGEs were inoculated on commercially pure (CP) titanium and RGD-grafted titanium. The number ofattached and proliferated cells was quantied by morphometric analysis using immunouorescence. The results showed that the bio-active peptide RGD was grafted on CP titanium by CDI activation method. The RGD grafting exhibited that the number ofattached and proliferated broblasts and epithelial cells were higher than that on CP titanium. The RGD-grafting is advantageous. to gingival cells adherence to the surface of titanium implant.

Secalonic acid D(SAD) was isolated as the major secondary metabolite of the marine lichen-derived fungus Gliocladium sp. T31. Its structure was established on the basic of physicochemical and spectroscopic data. This is the first report on the isolation of SAD from this fungus, as well as its inhibitory effect on K562 cell cycle and its cytotoxicity against several tumor cell lines in vitro.

Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. Methods Nine patients (age 18-53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). Results FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. Conclusions This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube. (J Neurogastroenterol Motil 2017;23:289-297)

An endophytic Streptomyces sp. (AC-2) was isolated from the root of Cistanches deserticola Y.C.Ma.. Chemical investigations of the culture broth of AC-2 afforded fifteen compounds including K1115 A (1), tyrosol (2), phenylethylamine derivatives (3, 4), cyclic dipeptides (5-8), nucleosides and their aglycones (9-13), N-acetyltryptamine (14), and pyrrole-2-carboxylic acid (15). Only tyrosol can promote an increase of intracellular cAMP special on GPR12 transfected cells, such as CHO and HEK293, which means it may be a possible ligand for GPR12.
