    Notes: Fifteen college students attempted to deceive a professional polygraph examiner, while 15 others who had nothing to hide also submitted to the examination. The examiner was blind as to whether each subject was deceptive or truthful. Using the skin conductance response (SCR), significant discrimination was made between deceptive and truthful subjects with both “guilty person” and “guilty knowledge” polygraph tests. On both types of test, however, subjects who were not detected were significantly less socialized (Socialization Scale of the California Psychological Inventory) than those who were detected. This reduced susceptibility to detection was mediated by a reduced SCR to deception among low-socialization subjects. Among innocent subjects the highly socialized were more responsive electrodermally throughout the test, leading some of them to be misclassified as deceptive on at least one test. Implications of the results for both detection of deception and the construct of socialization are discussed.

    Notes: Summary Gene duplications must play an important role in the evolutionary development of living organisms. Presented here is a general scheme that uses complementary alleles to isolate gene duplications in diploid organisms. The technique was used inDrosophila melanogaster to assess the rate of spontaneous gene duplication at two loci, maroon-like and rosy. The results indicate (1) that the rate of duplication of the maroon-like locus is on the order of 2.7×10−6; (2) that the rate of duplication of the rosy locus is approximately 1.7×10−4; and (3) that duplication occurs in males, suggesting that there may actually be two modes of gene duplication inDrosophila melanogaster.

    Notes: Abstract The authors describe a case of pancreatic pseudocyst presenting as an intramural gastric mass on upper gastrointestinal examination (UGI) and computed tomography (CT) of the abdomen. The correct diagnosis of this rare entity was suggested preoperatively on the basis of the radiographic findings presented herein.

    Notes: Summary Vomifoliol, a compound related to abscisic acid (ABA) but lacking the 2,4-pentadiene sidechain and so far found in four different plant families, caused as much stomatal closure in epidermal strips of Eichhornia crassipes (Mart.) Solms as ABA at identical concentrations. It appears worthwhile to investigate whether vomifoliol plays a role as an endogenous regulator of stomatal aperture.

    Notes: Summary (+)-Vomifoliol was shown to be as rapidly acting as (±) abscissic acid in stomatal closure time studies which involved the use of Eichhornia crassipes (Mart) Solms epidermal strips. (±)-Vomifoliol was shown to be less effective, while 4-(1-hydroxy-4-keto-2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) had only a slight effect in the same bioassay system. (+)-Vomifoliol showed no significant effect on the germination of lettuce seeds or the growth of cucumber seedlings.

    Notes: Heat shock has a profound influence on the metabolism and behavior of eukaryotic cells. We have examined the effects of heat shock on the release from cells of arachidonic acid and its bioactive eicosanoid metabolites, the prostaglandins and leukotrienes. Heat shock (42-45°) increased the rate of arachidonic acid release from human, rat, murine, and hamster cells. Arachidonate accumulation appeared to be due, at least partially, to stimulation of a phospholipase A2 activity by heat shock and was accompanied by the accumulation of lysophosphatidyl-inositol and lysophosphatidylcholine in membranes. Induction of arachidonate release by heat did not appear to be mediated by an increase in cell Ca+ +. Stimulation of arachidonate release by heat shock in hamster fibroblasts was quantitatively similar to the receptor-mediated effects of β thrombin and bradykinin. The effects of heat shock and β thrombin on arachidonate release were inhibited by glucocorticoids. Increased arachidonate release in heat-shocked cells was accompanied by the accelerated accumulation of cyclooxygenase products prostaglandin E2 and prostaglandin F2α and by 5-lipoxygenase metabolite leukotriene B4. Elevated concentrations of arachidonic acid and metabolites may be involved in the cytotoxic effects of hyperthermia, in homeostatic responses to heat shock, and in vascular and inflammatory reactions to stress.

    Notes: Capillary endothelium can actively regulate vascular permeability of various serum proteins. Hormones such as insulin must interact with this capillary barrier in order to reach their respective target tissues. We have studied the binding and subsequent internalization of 125I-insulin in both native (freshly isolated) and primary cultured capillary endothelium derived from rat epididymal fat pads. Insulin association with the endothelium, internalization and degradation differed between freshly isolated and primary cultured capillaries. Specific binding in freshly isolated and cultured capillaries was temperature dependent, and was competitively inhibited in the presence of unlabelled insulin. Primary cultures of capillaries grown to confluence did not exhibit specific binding of insulin. Despite the lack of specific receptors for insulin, cultured cells vesicularly internalized insulin. Greater than 50% of the total associated insulin was not degraded by cultured endothelium. Morphological examinations using ferritin labelled insulin localized insulin associated to the capillary endothelial cell membrane and sequestered within pinocytotic vesicles. Incubation of freshly isolated capillaries with insulin stimulated the fluid phase endocytosis of 14C-sucrose; however, insulin had no effect on fluid phase endocytosis in cultured capillaries. These results indicate that capillary endothelium, isolated from rat epididymal fat, exhibit specific receptors for insulin. Binding of insulin to the capillary membrane is followed by internalization into cytoplasmic vesicles and partial degradation.
