Eicosanoids Act In Nodulation Reactions To Bacteria Serratia Marcescensin Hemipteran Pest, Eurygaster Integriceps, Hasan Tunaz
Turkish Journal of Biology
In insects, nodulation is the first step in cellular defense reactions to bacterial, fungal, and some viral infections. The hypothesis was posed that the hemipteran pest E. integriceps produces melantoic nodulation reactions to bacterial challenge and that eicosanoids mediate these reactions. Treating the adult of E. integriceps with Serratia marcescens induced nodulation reactions in a challenge dose-dependent manner. Injecting the adult E. integriceps with eicosanoid biosynthesis inhibitors, immediately before intrahemocoelic injections of the bacterium Serratia marcescens, sharply reduced the nodulation response to bacterial challenges. Separate treatments with specific inhibitors including dexamethasone (a phospholipase A_2 inhibitor), indomethacin, naproxen, ibuprofen, piroxicam (cyclooxygenase …

Turkish Journal of Biology
The effects of sub-chronic administration of an aqueous extract of Ficus bengalensis stem bark on hematological and biochemical parameters in rats with streptozotocin (STZ)-induced diabetes were evaluated. The possible protective effect of the F. bengalensis (500 mg/kg of body weight per day) extract on STZ-induced changes was evaluated over 12 weeks. The parameters evaluated were plasma proteins, including total protein albumin and globulin, non-protein nitrogenous substances, including urea, uric acid, and creatinine, and hematological indices, including total hemoglobin content, erythrocytes, leucocytes, and platelets counts. The aqueous extract had a significant (P < 0.05) protective effect against STZ-induced changes in terms of the markers of protein metabolism and hematological indices. Furthermore, increases in levels of non-protein nitrogenous substances were normalized in response to the administration of the extract. Thus, the aqueous extract of F. bengalensis had a significant protective effect on STZ-induced changes to biochemical and hematological parameters in the diabetic rats.

A Bacillus sp. identified as a Bacillus thuringiensis IAM 12077 strain capable of producing 10%-15% dry cell weight (DCW) PHB when grown in nutrient broth for 48 h was subjected to random mutagenesis [physical (UV) and chemical (acridine orange)]. Among the UV-mutants screened, 19 …

A plaque-purified genotypic variant, derived from a field isolate of the Malacosoma neustria nucleopolyhedrovirus (ManeNPV) from Turkey was characterized based on in vitro replication properties in a cell line, Md203 derived from Malacosoma disstria. The life cycle of ManeNPV was studied based on the cytopathic effects (CPEs), polyhedral inclusion body (PIB) formation, budded virus (BV) production, viral DNA replication and polyhedrin protein expression in ManeNPV-infected Md203 cells. Infection of Md203 cells with ManeNPV resulted in cytopathic effects within 24 and 36 h post infection and most cells detachted from the bottom of the culture plate on the fourth day. Typical …
