However, despite the important ecological roles that insects play in every ecosystem in which they exist, little research has been devoted to the description of insect immunity. Insects rely heavily on the rapid actions of innate immune mechanisms to prevent infection. We characterized the melanization response in the hemolymph of green darner dragonfly (Anax junius) nymphs. Incubation of chymotrypsin-activated hemolymph with L-DOPA resulted in volume- and time-dependent production of dopaquinone via the phenoloxidase (PO) enzyme, with biphasic accumulation of product. The PO activity was temperature-dependent, with a stepwise increase from 20˚C 35˚C and maximum activity measured at 35˚C - 40˚C. The formation of product was also inhibited in a concentration-dependent manner by diethyl-carbonate, a specific inhibitor of PO activity, which indicated that the observed activity was due to the presence of PO enzyme. The rate of formation and quantity of melanin was dependent on exposure to different titers of bacteria. This is the first characterization of both PO activity and melanization response in green darner dragonflies.","PeriodicalId":59114,"journal":{"name":"生物化学进展(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70475645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In one study, a subject population that was self-perceived to be fatigued was administered an undetaured beta-glucan, to determine if this supplementation affected their quality-of-life as a result of an increased immune system response. 44 subjects were administered 1 mg/mL bid of the undenatured be-ta-glucan (Lentinex ® ) for four weeks. Prior to the beginning of the administration, and following the four-week administration period, the subjects were asked to fill out a quality-of-life VAS questionnaire. The changes in the two questionnaires revealed differences that occurred as a result of the beta-glucan administration. More than 75% of the subjects scored “better” (more than 1 cm on the VAS) with regard to feeling in a good mood, and feeling rested. More than 60% increased their energy and reduced their tiredness and exhaustion, and 70% felt less stressed. In a second study, subjects aged 40 years and older, believed to be in good general health, seeking therapy for tired-ness/exhaustion/fatigue or similar conditions (neurasthenia) which were administered 1 mg/mL bid Lentinex ® . The overall results indicated that the subjects felt significantly better (mean VAS = 5.91) after the not functioning at optimal levels.","PeriodicalId":59114,"journal":{"name":"生物化学进展(英文)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70475941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
