OBJECTIVE In peritoneal dialysis (PD), neutrally buffered PD fluids with lower concentrations of glucose degradation products (GDP) have tested superior to conventional fluids in terms of biocompatibility. However, conventional in vitro studies provoke debate because, due to the lack of subsequent equilibration with the blood, they do not resemble the true(More)
Octopamine enhanced the release of JH3 from isolated corpora allata of locusts in short-term cultures. This effect was suppressed when phentolamine (inhibitor of the octopamine receptors) was added to the culture medium. Moreover an octopamine-sensitive adenylate cyclase was found in the corpora allata. The results suggest a positive octopaminergic control(More)
Attractiveness in adult females of Calliphora vomitoria is correlated with ovarian development and there is a marked increase during the previtellogenic and vitellogenic periods. The development of attractiveness may result from the combined actions of ecdysteroids and juvenile hormone. A rise in total hydrocarbons parallels the first increase in levels of(More)
An in vitro method has been developed for the investigation of the regulation of juvenile hormone biosynthesis by insect corpora allata. Glands were maintained in Marks medium 19AB and JH synthesis quantified by a modified radioimmunoassay for juvenile hormone I. The radioimmunoassay is specific for JH I and exhibits approximately 12.6% cross reactivity(More)
JH III is the only JH detected by GLC-MS in medium from in vitro incubations of corpora allata of adult females ofCalliphora vomitoria. When corpora allata were removed from females at various times during the reproductive cycle and the JH III produced by the glands in vitro measured by a JH III radioimmunoassay, an increase in the level of synthesis was(More)

The allatectomy in the 4th instar larvae of Rhodnius prolixus stops moulting in 93 per cent of the cases. A different type of moulting results in these larvae after the injection of ecdysone or ecdysterone. The ecdysterone induced a rapid apolysis with a new adultoid cuticle tending towards larval but with the ecdysone, apolysis occurred at normal times and(More)
A fall in diurnal rearing temperature (from 33°C to 28°C) during the 2 last larval instars ofSchistocerca gregaria induces a lengthening of development and a slowing down of growth. At 28°C, circulating levels of juvenile hormones, particularly those of JH3, diminish from the middle of the 4th instar but ecdysteroids and proteins accumulate in haemolymph.
BACKGROUND In peritoneal dialysis, the usage of automated peritoneal dialysis (APD) has been steadily increased. As APD means larger volumes of solution and more frequent contact times with fresh dialysate, an additive negative impact on biocompatibility data, exceeding the known effect of conventional PD fluids, seems possible. For an in-vitro comparison(More)
