Two eyestalk (ES) neuropeptides, molt-inhibiting hormone (MIH) and crustacean hyperglycemic hormone (CHH), increase intracellular cGMP levels in target tissues. Both MIH and CHH inhibit ecdysteroid secretion by the molting gland or Y-organ (YO), but apparently through different guanylyl cyclase (GC)-dependent pathways. MIH signaling may be mediated by nitric oxide synthase (NOS) and NO-sensitiv...

Next-generation-sequencing (NGS) has revolutionized the field of genome assembly because of its much higher data throughput and much lower cost compared with traditional Sanger sequencing. However, NGS poses new computational challenges to de novo genome assembly. Among the challenges, GC bias in NGS data is known to aggravate genome assembly. However, it is not clear to what extent GC bias aff...

We compared the performance of gas chromatography time-of-flight mass spectrometry (GC-MS) and comprehensive two-dimensional gas chromatography mass spectrometry (GC×GC-MS) for metabolite biomarker discovery. Metabolite extracts from 109 human serum samples were analyzed on both platforms with a pooled serum sample analyzed after every 9 biological samples for the purpose of quality control (QC...

We immunohistochemically defined the histogenesis of posttransplantation lymphoproliferative disorders (PTLDs; B-cell phenotype) occurring after allogeneic T cell-depleted hematopoietic stem cell transplantation (HSCT; n = 15) or solid organ transplantation (SOT; n = 11) to determine whether transplantation type or morphologic subtype of PTLD affected the histogenetic subtype. Immunohistochemic...

background & aim: lamiaceae is one of the most important families of plants with global transmittal. the family is divided to two major groups: lamioideae and nepetoideae. mentha l. genus has high genetic variation because of different ploidy levels and interspecific interspecific hybridization thus that is possible to select genotypes with excelsior traits as essence content. the genus inc...

gc-fid and hplc-dad were developed for determination of menadione (mn) and menadione sodium bisulphite (msb). by means of each method, quantitative analysis of msb in commercial pharmaceutical was performed in both direct analysis of msb and analysis of mn by converting msb to mn with sodium carbonate. gc-fid method was carried out on the hp-5 capillary column using nitrogen gas. hplc-dad metho...
