Conclusion: Prescription of bimodal UF during the day in APD patients offers
the opportunity to optimize the long dwell exchange in a complete 24-hour APD cycle. The current study demonstrated that a bimodal solution based on the mixing of glucose (2.6%) and icodextrin (6.8%) achieved the double target of significantly improving UF and peritoneal sodium removal by exploring a new concept of glucose-sparing PD therapy.”
“OBJECTIVE: Placenta has the highest expression of epidermal growth factor (EGF) receptor of all tissues, a cell signaling pathway promoting survival and growth. Therefore, EGF receptor inhibition could potentially treat ectopic pregnancy. We undertook preclinical studies to examine whether gefitinib (orally available EGF receptor inhibitor) with or without methotrexate inhibits placental cell growth.
METHODS: Gefitinib and methotrexate MS-275 were added to placental cells and their ability inhibit PD-1/PD-L1 inhibitor review cell growth, block EGF receptor signaling, and induce apoptosis (programmed cell death) was examined. They were also administered to two animal mouse models to examine their effects on placental tissue in vivo.
Results: Epidermal growth factor receptor was highly
expressed in placental tissue from ectopic pregnancies. Combining gefitinib with methotrexate potently inhibited growth of placental cells, including placental cell lines (JEG3, BeWo cells) and cells isolated from first-trimester placenta. These drugs were additive in blocking EGF receptor signaling and inducing apoptosis. Gefitinib and methotrexate administered together were more potent in decreasing the volume of human placental cells xenografted subcutaneously onto mice compared with either alone. By day 19 after xenografting, mean (+/- standard error of the mean), xenograft volumes were: 821 (+/- 68) mm(3) after
gefitinib treatment, 901 (+/- 204) mm(3) after methotrexate treatment, and 345 (+/- 137) mm(3) after both drugs were given (P<.01 for both comparisons of single therapy compared with combination therapy). Combining these agents doubled rates of fetal resorption in pregnant mice compared with each drug alone.
CONCLUSION: LXH254 nmr Combining gefitinib with methotrexate potently inhibits placental cell growth in vitro and in mouse models. The combination may have potential in treating ectopic pregnancies.”
“Biodegradation of nonylphenol polyethoxylates (NPEO) has been studied in laboratory column bioreactors with a polyethylene carrier on which destructor bacteria of Pseudomonas surface-active compounds were immobilized. To monitor the efficiency of microbial treatment of model wastewater, a biosensor based on the oxygen Clark electrode and destructor bacteria of NPEO from bioreactors was designed. The designed biosensor allowed us to detect the content of polyethylene glycol monoalkyl phenyl ether on the basis of polymer distillate (OP-10), which is a commercial NPEO preparation, in samples in the range of 1-200 mg/l.
