Published 1998Staff ViewISSN: 1439-0523Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: A factorial crossing scheme of Cofflea canephora (two parents from the Congolese group crossed to 14 parents of the Guinean group) was used to evaluate genetic parameters of several biochemical compounds, bean weight and crop outturn (ration of dry bean weight 10 fresh berry weight). For most characters studied, additive genetic effects were preponderant. Narrow-sense heritability was high for caffeine content (h2ns= 0.80), fat matter content (h2ns, = 0.74), bean weight (h2ns= 0.73) and crop outturn (h2ns= 1). It was intermediate for trigonelline (h2ns= 0.38) and chlorogenic acid (h2ns= 0.36) content. Only sucrose content had a low narrow-sense heritability (h2ns=0.11). There were few genetic and enviromnental correlations, Consequences for breeding, in relation to coffee drinking quality, are discussed.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1600-0846Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background/aims: Although there are many reports of regional variations in skin response to various stimuli, only a few studies have been performed on the face. The forearm is the most often used test site while the face is a frequent and specific target of many topical agents (drugs and cosmetics) and cosmetic procedures. The aim of this study was to compare regional variations of cutaneous sensation and skin barrier function in the cheek, neck and forearm before and after application of different stimuli (physical and/or chemical).Methods: Physiological changes of the skin were measured by non-invasive methods: TEWL (transepidermal water loss) and skin capacitance. Furthermore, clinical scoring and subjective sensations were reported. The anatomical sites evaluated were cheek, neck and volar forearm.Results: Great differences in clinical reactions, subjective sensations and skin barrier function in response to various stimuli have been observed between tested areas (cheek, neck and forearm). We observed a greater “sensitivity”, i.e., more severe clinical reactions and subjective sensations of the cheek and neck areas, in relation to chemical stimuli as compared to the forearm. After a mechanical stimulus, the forearm was the most sensitive site, but just for subjective sensations. Concerning skin barrier function, the cheeks exhibited the highest values of TEWL and the forearms the lowest.Conclusion: In view of the high “sensitivity” of the cheek as compared to the forearm, it will be more cautious to assess the safety of facial cosmetics on the sites of intended use.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1365-2133Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Summary Human hair growth can be monitored for several months after the transplantation of scalp samples from men with androgen-dependent alopecia on to female nude mice. Hair production from balding sites has been shown to be inhibited in testosterone-conditioned nude mice. We used this recently reported model to study the effect of a new non-steroidal antiandrogen – RU 58841 – on human hair growth. Twenty productive scalp grafts from balding men were maintained for 8 months after grafting on to nude mice, and hair production was monitored monthly for 6 months. All mice were conditioned by the topical application of testosterone (testosterone propionate. 300 μg in 10μL; 5 days/week) on the non-grafted flank. The scalp samples were divided equally according to the estimated hair production potential, which was based on the amount of hair present on the scalp samples before grafting. Each of the two equal groups of grafts was further allocated at random to be treated topically (5 days/week) with blinded solutions of either RU 58841 1% in ethanol, or ethanol as a control.Twenty-eight active follicles appeared on the 10 control grafts. Among them only two follicles (7%) initiated a second hair cycle. However, the 10 RU58841-treated grafts bore a total of 29 active follicles, and eight of them (28%) showed a second cycle. The values for the linear hair growth rates (LHGR) were significantly (P〈0.04) higher in the RU58841-treated group. Recycling and increased LHGR indicate a positive action for RU58841 on human hair growth from balding samples grafted on to testosterone-conditioned nude mice, and encourage a clinical trial to evaluate its potential in the treatment of androgen-dependent alopecia.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1106Keywords: Spinal cord ; Corticospinal system ; Wallerian degeneration ; Synaptic ultrastructureSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary An examination of the precise mode of termination of the corticospinal system in the spinal cord of rodents has been conducted by use of light and electron microscope methods. This study confirms the position of the normal corticospinal tract in rodents in the ventralmost portion of the dorsal column white matter. Three to four days following unilateral sensorimotor cortex ablation, Nauta-Gygax and Fink-Heimer silver methods reveal a dorsomedial projection of degenerating debris into the dorsal horn from the contralateral corticospinal tract. Although the silver methods do not show degeneration at survival times earlier than two days, the electron microscope shows degenerating axons and synaptic knobs as early as 24 hours following cortical lesion. The degenerating synaptic knobs are found only in the dorsal regions of the dorsal horn subjacent to the substantia gelatinosa. They usually make synaptic contact with several small to medium sized dendrites. These terminals do not appear to participate in axosomatic or axoaxonal synapses. No degeneration is seen in the ipsilateral corticospinal tract, the lateral white columns, or the ventral horn of the spinal cord.Type of Medium: Electronic ResourceURL: -

Somatic embryos were co-cultivated with the LBA4404 strain of Agrobacterium tumefaciens containing the cry1Ac gene. More than 100 transformed plants from independent transformation events were obtained for each coffee genotype. The integration and expression of the cry1Ac gene was studied, and effective resistance of transgenic plants against leaf miner was verified in bioassays with the insects. These plants could represent a good opportunity to analyse the impact of genetic engineering of perennial crops for sustainable resistance to an obligate endocarpic pest using a B. thuringiensis insecticidal protein.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-6679Source: Springer Online Journal Archives 1860-2000Topics: Theology and Religious StudiesNotes: Abstract The principal concern of this essay is the spiritual growth which life crises make possible. My assumptions are a) that every crisis can arouse within us a fresh awareness of the transcendent source of and goal for every human life, and b) that precisely in the trauma which every crisis brings, we are given the opportunity to reassess the principles by which we have lived, in the direction of a more encompassing and adequate set of values, informed by a deeper faith. For such reassessment to occur, however, we must be willing to call into question our whole lives, and not just those decisions contributing to the specific crisis now confronting us. I believe that close to the very heart of pastoral work is that enlivening and encouraging pastoral presence which supports change in the face of obstacles and overwhelming anxiety, and which mediates the Giver of Life in a way which makes radical change truly possible. I elaborate upon this conviction in two sections: the first discusses the role of the pastor in crisis intervention and the second advances the claim that exacerbating a sense of crisis for the sake of facilitating peoples' growth in faith is the uniquely pastoral contribution to helping people in crisis.Type of Medium: Electronic ResourceURL: -

Results are presented here on intergroup cross progenies evaluated on individual plant basis over a six year period in three fully randomized trials planted in 1985 and 1986. Yields of the bi-parental crosses varied from 16 to 1407% of the mean of the two commercial clonal cultivars and the most productive crosses were also the most vigourous. Selection of individual trees and cross progenies, based on a combined individual-family index, was carried out for high yield, good vigour of young plants and moderate canopy diameter of adult trees. Expected genetic gains, as estimated in relation to the mean of all crosses, for selection of 5% of the best trees, were high for yield (over 60%), moderate for young plant vigour (14 to 18%), and, as intended, low for canopy diameter. In addition, selection by independent culling for leaf rust resistance and bean weight was carried out. As a result, 6 promising crosses with yield similar or higher than those of the control cultivars, were selected as candidates for commercial use, as well as 65 individual trees, within 19 different crosses. Expected genetic gain for yield for these selected trees is about 60% compared to the average yield of the most productive control clone. Continuation of the programme is discussed, with specific attention to further progress expected for quality traits.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5060Keywords: Coffea canephora ; germplasm ; hybrid vigour ; yield ; organoleptic quality ; coffee leaf rust ; coffee twig-borerSource: Springer Online Journal Archives 1860-2000Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Summary Two breeding populations have been identified with Coffea canephora, based on geographical and genetic differences: the Guinean group from West Africa and the Congolese group from central Africa. A reciprocal recurrent selection programme based on these groups was initiated in Côte d'Ivoire in 1984. Genotypes of both groups available in field collections are either of cultivated or wild origin. Genotypic and phenotypic variability was evaluated within and between the groups for the following characteristics: isozyme patterns, architecture, drought tolerance and vigour, technological and organoleptic traits, pest and disease resistance. Variation between and within groups was found to be large. Based on isozyme analysis and phenotypic observations, two subgroups were identified within the Congolese group. Phenotypic values of parents and testers used in the first cycle of reciprocal recurrent selection are presented. Results of two intergroup hybrid trials indicate high yield and vigour for these hybrids compared to intragroup hybrids, justifying the reciprocal selection approach. Furthermore, the variation observed indicates that recurrent selection would allow progress for selection traits for both populations and intergroup hybrids.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5060Keywords: Coffea canephora ; reciprocal recurrent selection ; genetic parameters ; genetic variance ; parent-offspring regressions ; genetic correlations ; heritabilitySource: Springer Online Journal Archives 1860-2000Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Summary Genetic parameters were estimated in trials planted in connection with a reciprocal recurrent selection programme applied to Coffea canephora in Côte d'Ivoire. Narrow sense heritability values, estimated from a breakdown of the analysis of variance, were high for architectural characters (0.22 to 0.78) and medium for tree vigour (0.13 to 0.40) and for bean weight (0.15 to 0.28). Calculated heritability values for the first two harvests were high (h2〉0.7), but much lower for the following harvests (less than 0.2). Heritability estimates by parent-offspring regressions gave variable results, though they were often similar to those obtained by variance analysis, especially for bean weight. Phenotypic and genetic correlations between tree vigour traits and productivity were high. Bean weight was not correlated with vigour or production. Canopy diameter of 4 year-old trees was closely correlated with cumulated productivity from 2 to 5 years in the absence of development competition between trees, but the correlation was low if trees were in competition with each other. The consequences of the results for the choice of characters to be selected among intergroup hybrids or the parents of both populations are discussed.Type of Medium: Electronic ResourceURL:
