Angiotensin II (AII, 5 micrograms) injected into the cerebral ventricles produced hypothermia in conscious rats at ambient temperatures (Ta) of 18, 23, and 28 degrees C. At Ta of 18 and 23 degrees C, AII-induced hypothermia was attributed to both enhancement of heat loss and suppression of metabolic rate. At Ta of 28 degrees C, AII-induced hypothermia seemed to be mainly attributed to increased...

Depending on their phospholipid composition, liposomes are endocytosed by, or fuse with, the plasma membrane, of Acanthamoeba castellanii. Unilamellar egg lecithin vesicles are endocytosed by amoeba at 28 degrees C with equal uptake of the phospholipid bilayer and the contents of the internal aqueous space of the vesicles. Uptake is inhibited almost completely by incubation at 4 degrees C or ...

Excretion rates of ammonia-N, nitrite-N, nitrate-N, and dissolved organic nitrogen (DON) for juvenile Litopenaeus vannamei (3.85+/-0.83 g) were quantified in response to nine different combinations of temperature (24, 28, and 32 degrees C) and salinity (10, 25, and 40 ppt) under laboratory conditions. Results indicated that L. vannamei is ammonotelic, with ammonia-N accounting for 61.9-84.3% of...

Escherichia coli colonizes the gastrointestinal tract of humans; however, little is known about the features of commensal strains. This study investigated whether expression of the biofilm extracellular matrix components cellulose and curli fimbriae is found among commensal isolates. Fifty-two E. coli strains were isolated from faecal samples and, as a control, 24 strains from urinary tract inf...

In the labellar chemosensory hairs of the blowfly, Phormia regina Meigen, stationary amplitudes of the slow potentials induced by salt and sugar stimulations were decreased to 50-80% at 12 degrees C of the values measured at 28 degrees C. The amplitudes induced by water did not show any dependence on temperature change. The maximum rate of rise of the receptor potentials was strongly increased ...

Three new direct-service staff participated in a program that used a video model to train target skills needed to conduct a discrete-trial session. Percentage accuracy in completing a discrete-trial teaching session was evaluated using a multiple baseline design across participants. During baseline, performances ranged from a mean of 12% to 63% accuracy. During video modeling, there was an imme...

BACKGROUND The human ability to envision the future, that is, to take a future perspective (FP), plays a key role in the justice motive and its function in transcending disadvantages and misfortunes. The present research investigated whether individual (Study 1) and situational (Study 2) differences in FP moderated the association of general belief in a just world (GBJW) with psychological resi...

OBJECTIVE To examine the opinions of Libyan doctors regarding the quality of drug information provided by pharmaceutical company representatives (PCRs) during detailing visits. METHOD An anonymous survey was conducted among 1,000 doctors from selected institutes in Tripoli, Benghazi and Sebha. Doctors were asked questions regarding the quality of information provided during drug-detailing vis...
