The Relationship

The distances between homologous, homeologous and unrelated telocentrics in hexaploid wheat and between homologous telocentrics in wheat-Aegilops speltoides amphiploids were measured in somatic metaphases. No significant differences were found in the mean distances between telocentric chromosomes of the four groups. Except for the homologous telocentrics in the amphiploids, the other three groups of measurements differed significantly from the theoretical distribution described for randomly distributed chromosomes by Feldman et al. (1966). The chromosomes of these three groups appeared to be closer to each other than expected for randomly distributed chromosomes according to the relationship proposed by Feldman et al. It is suggested that the theoretical distribution is only an approximation of the actual situation.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

A considerable number of dwarf plants (16.4 to 85.7 per cent) was found in C2 to C5 generations of four artificially-induced barley autotetraploids from the varieties OA.C. 21, Brant, York and Montcalm.The Montcalm tetraploid, which was the lowest in mean fertility, had the highest percentage of dwarfs. In the other three tetraploids there was no apparent relationship between the frequency of dwarfs and the mean per cent fertility. In the O.A.C. 21 tetraploid continuous selection for plants with high fertility did not reduce the occurrence of dwarfs.Most of the dwarf plants were aneuploids with 26, 27, 29, 30 or 31 chromosomes, but plants with identical number of chromosomes often showed differences in phenotype. Among the aneuploids 29-chromosome plants were most frequently found. The 26- and 31-chromosome plants were completely sterile. Only a low percentage of the other aneuploid plants produced seed. By considering the observed percentages of dwarf plants and the ratio of hypoploids to hyperploids produced, the largest part of sterility in the four barley autotetraploids could be attributed to irregular chromosome distribution.

Three Chinese Spring ditelocentric lines and four Agropyron telocentric addition lines were crossed with a single population of Aegilops speltoides. Chromosome pairing was studied in the hybrid plants. The mean chiasma frequencies per cell in different hybrid plants indicate the existence of three different genotypes in the population of Ae. speltoides each differing significantly in ability to suppress the diploidizing mechanism in polyploid wheat. Plants at the three levels of pairing showed means of 6.4, 10.4 and 15.0 chiasmata per cell, respectively.Agropyron telocentric chromosomes did not pair with their wheat homoeolgues at the lowest pairing level. At intermediate and high pairing levels they did pair with wheat chromosomes. The increase in pairing of Agropyron telocentrics paralleled the increase in chiasma frequency per cell.The action of genes controlling homoeologous synapsis is discussed and it is suggested that pairing affinity between chromosomes may result from the interaction between two factors: homology in nucleotide sequences at specific sites in chromosomes, and degree of activation of these sequences.

Meiotic Competence

The present study was conducted to examine the effects of the stage of the oestrous cycle on the meiotic competence of canine oocytes and also to investigate the relationship between the stage of the oestrous cycle and the relative size distribution of oocytes obtained from bitches at three stages of the cycle (anoestrus, follicular phase and dioestrus). Only healthy-looking cumulus–oocyte complexes were used for in vitro maturation and these were divided into three groups based on diameter (<110, 110 to <120 and ≥120 µm). The mean diameter of oocytes from ovaries at anoestrus, the follicular phase and dioestrus was 103.6, 119.2 and 107.7 µm, respectively. The percentage of large oocytes (120 µm) collected at the follicular phase was higher (P<0.01) than that collected at dioestrus and the percentage of oocytes ≥120 µm collected from ovaries at dioestrus was higher (P<0.01) than that collected at anoestrus. After culture for 72 h, significantly more oocytes reached metaphase II (MII) in the follicular phase than in the other stages (P<0.01), and more oocytes reached MII in dioestrus than in anoestrus (P<0.05). In the ≥120 µm group, the frequency of oocytes that resumed meiosis in the follicular phase was higher (P<0.05) than in the other stages. However, in the smaller diameter (<120 µm) groups, there were no significant differences between ovaries at different stages of the oestrous cycle with respect to the proportion of oocytes reaching each stage of meiosis. Thus, the oestrous cycle stage influences maturation frequency. Moreover, oocytes demonstrated a size-related ability to undergo meiotic maturation, irrespective of the stage of the oestrous cycle. These results suggest that the effects of the stage of the oestrous cycle may result from differences in the distribution of large oocytes.

SUMMARYDistribution ofLeptorhynchoides thecatus(Acanthocephala: Rhadinorhynchidae) among the pyloric caeca and the relationship between site and rate of maturation were studied in laboratory infectons of 10, 25 and 40 cystacanths fed to green sunfish,Lepomis cyanellus. After 1 week fish fed at each intensity had significantly different numbers of worms. By the 3rd week post-infection, parasites disappeared from the anterior portion of the intestine. At this time the mean numbers of worms recovered from 25 and 40-cystacanth infections were not significantly different. At the end of the 1st week, the area where caeca join the alimentary tract (between caecal area) and caeca numbered 6 and 7 contained significantly more worms than the other sites. By the 3rd week post-infection only caecum 7 contained significantly more worms, and at 5 weeks there was no significant difference between the number of worms present in any caecum or the between caecal area. Initially worms in the more intense infections matured more slowly, but by the 3rd week post-infection there was no significant difference in the states of maturity. The rate of maturation was not related to the site occupied.

The relationship of wet weight (WT) to cephalothorax width (CW) and temporal and seasonal variations in the condition factor were analyzed for each sex of the mangrove crab Ucides cordatus, using specimens collected monthly from September 1998 through September 2000, at Iguape, state of São Paulo. The WT/CW relationship, determined by the regression analysis and the condition factor were evaluated individually, monthly and seasonally, for each sex. The WT/CW relationship indicated isometric growth in males and negative allometric growth in females. Body weight was higher in males than in females of equivalent size and this difference was associated with the males' faster growth and heavier chelipeds. On the other hand, the means for condition factor were always higher for females than for males; the mean condition factor was lower in spring and summer and higher in autumn and winter.

Chloroplast Genomes

The nucleotide sequence of the chloroplast genome of the diploid wheat Triticum sinskajae A. Filat. et Kurk. was determined. The comparison of the assembled genome with the chloroplast genomes of some di- and polyploid species of the wheat-aegilops alliance revealed a high evolutionary conservativeness and proximity to the plastid genome of T. monococcum, while the other diploid wheat T. urartu is somewhat distant from them. Alignment of the nucleotide sequences of complete chloroplast genomes of diploid wheat with those of diploid aegilops from the Sitopsis and Vertebrata sections, as well as with tetra - and hexaploid wheat from the turgidum-aestivum and timopheevii groups, allowed to establish that different aegilops from the subsection Truncata, close to the current Aegilops speltoides, were as maternal forms during their formation but not directly Ae.speltoides.

Abstract. The relationship between the TSH and prolactin (Prl) responses to TRH has been investigated in 36 patients with prolactinoma, in 12 patients with symptomless autoimmune thyroiditis (SAT) and in 10 patients with Graves' disease in remission (GD). Autoimmune thyroiditis in combination with prolactinoma was found in 3 patients. The TSH -response was exaggerated in 4 prolactinoma patients without autoimmune thyroiditis. Moreover, in the patients with prolactinoma and intact function of the non-tumours pituitary gland the mean TSH increment was higher than in the controls. In patients with SAT, on the other hand, the Prl-response to TRH was significantly greater than that in the controls and in patients with GD. The significance of these findings is not obvious but they suggest that TRH may be involved in the development of prolactin secreting adenomata.

Cannula Placement

AbstractMedical patients receiving IV therapy were randomly assigned to one of two IV tubing change groups. One group had a 48-hour tubing change and the other had no tubing change for the remainder of the cannula placement. A daily IV fluid specimen was processed microbiologically. To complete the study, a minimum of 3 continuous days of therapy and three fluid specimens was required. There were two contaminated specimens, one in each tubing change group. The contamination rate in the 48-hour change group was 0.87% and 0.96% in the no change group. The rate difference of 0.09% has a 95% confidence interval (−0.035 to +0.036) which includes zero. Survival analysis also revealed no significant difference in the cumulative probability of survival, however the mean duration of continuous tubing use of 4.3 days in the no change group and 1.8 days in the 48 hour change group were significantly different (p<0.05). The cumulative probability of surviving contamination free was 0.988 in the 48-hour group and 0.987 in the no-change group. We conclude that it is safe to change IV tubing at intervals up to but not exceeding 4 days.
