OBJECTIVE To explore the pharmacokinetic interaction between isotretinoin, a cytochrome P-450 (CYP) inducer and potent teratogen, and the etonogestrel contraceptive implant. Study Design We enrolled healthy reproductive-age women initiating isotretinoin and using an etonogestrel implant. We compared serum etonogestrel concentrations at baseline and after four and nine weeks of isotretinoin co-administration using a validated assay. RESULTS Among eight implant users, all serum etonogestrel concentrations remained >90pg/mL during isotretinoin co-administration with no significant changes from baseline (p=0.25, Friedman's test). CONCLUSION In this exploratory study, we found that isotretinoin did not cause serum etonogestrel concentrations to fall below the threshold for ovulatory suppression ( less then 90pg/mL) among implant users. IMPLICATIONS Reproductive-age women treated with isotretinoin require reliable contraception to prevent pregnancies impacted by teratogenic-effects. This small study demonstrates that contraceptive implant users maintained serum etonogestrel concentrations above the threshold for consistent ovulatory suppression during isotretinoin co-administration. The contraceptive implant remains an appropriate option for patients considering isotretinoin therapy. In this study, pressurized liquid extraction (PLE) of polyphenolic-polysaccharide (PP) from Pseuderanthemum palatiferum (Nees) Radlk. leaves was carried out and compared with a conventional technique using 0.1 M sodium hydroxide. The extracts were purified according to the method reported previously to obtain PP conjugates which were further studied about chemical profiles and anticoagulant activity. Fourier-transform infrared spectroscopy (FTIR), UV-Vis, nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), and spectrophotometry analysis were used to characterize the selected PP conjugates. The results showed that PP conjugates comprised of carbohydrate, phenolic, and protein constituents with the yield ranged from 2.76% to 14.34%. Seven mono sugars containing in all conjugates were determined using high-performance liquid chromatography (HPLC), namely, arabinose, fucose, galactose, glucose, mannose, rhamnose, and xylose. PP conjugates obtained from PLE at 150 °C (PP-PLE5) exhibited better anticoagulant activity than those found at 200 °C and comparable to that of the conventional technique. On gel permeation chromatography, PP-PLE5 showed a broad molecular mass from 6 to 642 kDa. From the obtained results, PLE can be used as a green effective technique for the recovery of PP conjugate from P. palatiferum leaves. BACKGROUND Depression is the most debilitating neuropsychiatric disorder, and psychosocial stressors are major risk factors for the onset of depression. Depression is closely associated with chronic inflammation and microglia are the principal mediators of inflammation in the central nervous system (CNS). Mefenamic acid (MA) and celecoxib are nonselective and selective inhibitors of cyclooxygenase (COX), respectively. COX is a key enzyme in mediating inflammatory response in microglia. In this study, we examine the effects of inhibiting COX by MA on depressive-like behaviors and microglia activation in the hippocampus. METHODS We evaluate the effect of MA on chronic mild stress (CMS) induced depressive-like behavior by sucrose preference and forced swimming tests. Effect of MA on microglia activation in dentate gyrus (DG) of hippocampus was examined by immunohistochemistry. In vitro experiments including western blotting and phagocytosis assay were used to investigate the effect of MA on microglia activation. RESULTS Behavioral assays reveal MA and celecoxib ameliorate CMS-induced depressive-like behavior. AMG-900 datasheet Compared to the stressed mice, the number of activated/phagocytic microglia (Iba1+/CD68+) in DG of hippocampus significantly decreases in stressed mice treated with MA or celecoxib. MA and celecoxib play a role in inhibiting microglia activation by inhibiting of ERK1/2 and P38 MAPK activation and iNOS expression. MA or celecoxib also reduce the high phagocytic activity of activated microglia. CONCLUSION MA inhibits microglia activation/phagocytosis induced upon chronic stress in the hippocampus, which might result in the improvement of depressive symptoms. V.Sirex noctilio is an invasive Eurasian woodwasp that can kill pine (Pinus spp.) trees and has been introduced to areas of the Southern Hemisphere where plantations of introduced pines are grown. The main method of control of this invasive pest has been introduction and augmentation of a parasitic nematode, Deladenus siricidicola. The strain of D. siricidicola used for biological control of S. noctilio in the Southern Hemisphere originated in Sopron, Hungary. The genotype of D. siricidicola used for biological control sterilizes females of the strain of S. noctilio present in Australia. However, different strains of S. noctilio have been introduced to different geographic areas that have been invaded and different combinations of D. siricidicola and S. noctilio genotypes vary in whether these nematodes sterilize female S. noctilio. Moreover, even in the event of sterilization, partial sterilization can occur, where not all woodwasp eggs are compromised. Sirex noctilio has now invaded North America accidentallyting some limited variability in host specificity of this species. These results highlight the genetic diversity of Deladenus siricidicola in its native range in Europe. Bacillus thuringiensis (Bt) can synthesize insecticides to efficiently control insects. In this study, Bt strain S3580-1 with mosquitocidal activity was subjected to whole genome sequencing using an Illumina HiSeq 2000 system. A novel toxin, Cry80Aa1, was identified based on the resulting data. A conserved domain analysis revealed that Cry80Aa1 includes the Ricin_B_lectin domain (located at 10-150) and the Toxin_10 domain (located at 155-353). Phylogenetic tree analysis showed that Cry80Aa1 was in a distinct clade significantly distinguished from the known Cry proteins containing the Toxin_10 domain. Bioassays demonstrated that the Cry80Aa1 protein exhibited toxicity to third instar larvae of Culex pipiens pallens (LC50 71.9 μg/mL; 95% FL 59.5-122.7 μg/mL).
