Objectives: To determine the change in long saphenous vein (LSV) area in early pregnancy and the reversal postpartum in comparison with non-pregnant control values. Methods: Ultrasonography was used to determine the LSV areas at four different levels in the right and left legs of women in an erect position. The measurements from 69 nulliparous women were used to determine the non-pregnant baseline measurements for vein area. The vein areas were similarly measured from 39 primigravida women in early pregnancy and postpartum. Results: There was no significant difference found between measurements obtained from the right and the left legs. Non-pregnant baseline measurements were less than either the early pregnancy, or postpartum measurements obtained from the primigravida women. Conclusions: Physiological changes associated with early pregnancy induce dilation of the LSV, and the reversal postpartum is not complete with vein areas statistically larger than in the non-pregnant state.

The Activation-Deactivation Adjective Check List (AD ACL) is a multidimensional self-rating test constructed and extensively validated for rapid assessments of momentary activation or arousal states. The two core dimensions, energetic arousal (including tiredness) and tense arousal (including calmness) have been replicated repeatedly. They bear a complex relationship to each other involving positive and negative correlations at different levels of intensity. The dimensions are associated with a variety of arousal-related characteristics, including physiological changes, sleep-wake cycles, exercise effects, cognitive and information processing functions, various mood states, and a number of concomitants of stress. Finally, in a reported empirical study designed to investigate the somewhat uncommon self-rating format of this check list, alternative rating scales were employed with the same adjective descriptors. Factor analyses of respondents' ratings indicated that the factor structure of activation descriptors remained essentially the same with each scale. In this context, the importance of the underlying arousal model in relation to the activation descriptors is discussed.

Abstract: The objective of the study was to determine the physiological and isozyme alterations in lettuce seeds submitted to different conditions and storage periods. We used a completely randomized design with four replications in a factorial arrangement with six lettuce cultivars (Everglades, Babá de Verão, Elisa, Grand Rapids, Hortência and Salinas 88) and four storage periods (30, 60, 90 and 120 days), on three storage rooms (15, 25 and 35 ° C). The physiological quality was evaluated by first and final germination count, emergence, and germination and emergence speed indexes. The isoenzyme expression of catalase (CAT), esterase (EST), alcohol dehydrogenase (ADH) and malate dehydrogenase (MDH) were determined. The physiological quality of lettuce seeds was preserved when stored at 15 ° C room temperature. The high room temperatures associated with higher storage periods cause a reduction in physiological quality and alterations in enzymatic patterns of CAT, EST, ADH and MDH. For seeds stored at 15 ° C, there were no physiological changes. The lettuce cultivars, especially Everglades, have different levels of tolerance to storage and isoenzyme expressions.

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.

Some authors using immunofluorescent techniques had already suggested that some hepatocytes are able to synthetize several plasma proteins. In vitro studies on normal cells or on cells issued of murine hepatomas raise the same conclusion. These works could be indications of an hepatocyte functionnal non-specialization, meanwhile the authors never give direct topographic proofs suitable with this hypothesis.The use of immunoenzymatic techniques after obtention of monospecific antisera had seemed to us useful to bring forward a better knowledge of this problem. We have studied three carrier proteins (transferrin = Tf, hemopexin = Hx, albumin = Alb) operating at different levels in iron metabolism by demonstrating and localizing the adult rat hepatocytes involved in their synthesis.Immunological, histological and ultrastructural methods have been described in a previous work.

Abstract. Stress-related stimuli may be presented outside of awareness and may ultimately influence health by causing repetitive increases in physiological parameters, such as blood pressure (BP). In this study, we aimed to corroborate previous studies that demonstrated BP effects of subliminally presented stress-related stimuli. This would add evidence to the hypothesis that unconscious manifestations of stress can affect somatic health. Additionally, we suggest that these findings may be extended by measuring affective changes relating to these physiological changes, using measures for self-reported and implicit positive and negative affectivity. Using a repeated measures between-subject design, we presented either the prime word “angry” ( n = 26) or “relax” ( n = 28) subliminally (17 ms) for 100 trials to a student sample and measured systolic and diastolic BP, heart rate (HR), and affect. The “angry” prime, compared to the “relax” prime, did not affect any of the outcome variables. During the priming task, a higher level of implicit negative affect (INA) was associated with a lower systolic BP and diastolic BP. No association was found with HR. Self-reported affect and implicit positive affect were not related to the cardiovascular (CV) activity. In sum, anger and relax primes elicited similar CV activity patterns, but implicit measures of affect may provide a new method to examine the relationship between (unconscious) stress and health.
