A map with 51 markers (46 RFLPs and five isozymes) was constructed using an interspecific F2 population between ’Garfi’ almond (Prunus amygdalus Batsch.) and ’Nemared’ peach [Prunus persica (L.) Batsch.]. This map was developed by selecting markers covering most of the distance of the eight linkage groups from
previously constructed Prunus maps. The markers studied in this population mapped to seven linkage groups instead of the eight expected in Prunus. Markers belonging to groups 6 and 8 in previous maps formed a single group in the ’Garfi’×’Nemared’ F2 and several marker pairs placed in different groups in other maps exhibited tight linkages. The study of pollen fertility
and chromosome behavior during meiosis in the F1 generation allowed us to confirm the hypothesis that a reciprocal translocation exists between ’Garfi’ and ’Nemared’. Based
on independent evidence of linkage between markers and pollen fertility data in the F2 population, we concluded that the breakpoint of the reciprocal translocation was placed between markers AC50 and AG26A in
group 6 and between markers AG112A and FG230A in group 8.

Some causes of infertility can be prevented, as is the case for infertility of infectious origin. Genital infections represent a major source of infertility. Prostato-epididymitis consecutive to an urinary infection can be prevented by identifying and treating prostatic localizations at an early stage of urinary infection. The prevention of sexually transmitted diseases (STD), which cause male and female infertility, is, at the moment, accomplished by the prevention of the sexual transmission of the HIV. Teenagers represent a target of choice for the educational campaigns promoting condom use. The role of physicians, especially when teenagers are asking for a contraception, must be complementary to the public health campaign to decrease the spread of HIV and other STDs. 相似文献

On estime que le marché global de l’externalisation des dispositifs médicaux et de l’instrumentation représente actuellement
plus de 6 milliards d’euros. D’après les cadres dirigeants de l’industrie, cette tendance devrait non seulement se poursuivre,
mais aussi s’amplifier dans les années à venir. 相似文献

Congenital bilateral absence of the vas deferens is the most frequent abnormality of the male genital tract Diagnosis is clinical. Seminal patterns associate azoospermia, hypospermia, low PH, low seminal markers. Transrectal and renal ultrasonography search for abnormalities of the seminal vesicles and renal agenesis. Mutations of CFTR gene are found in more than 70% of all cases. Genetic council is necessary before ICSI. Results of ICSI with micro-epididymal sperm aspiration are the same as in the other cases of azoospermia. 相似文献

2’,3’-cyclic nucleotide 3’-phosphodiesterase (CNP) is a member of the interferon-stimulated genes, which includes isoforms CNP1 and CNP2. CNP1 is locally expressed in the myelin sheath but CNP2 is additionally expressed at low levels outside the nervous system. CNPs regulate multiple cellular functions and suppress protein production by association with polyadenylation of mRNA. Polyadenylation of Hepatitis B virus (HBV) RNAs is crucial for HBV replication. Whether CNPs interact with polyadenylation signal of HBV RNAs and interfere HBV replication is unknown. In this study, we evaluated expressions of CNP isoforms in hepatoma cell lines and their effects on HBV replication. We found that CNP2 is moderately expressed and gently responded to interferon treatment in HepG2, but not in Huh7 cells. The CNP1 and CNP2 potently inhibited HBV production by blocking viral proteins synthesis and reducing viral RNAs, respectively. In chronic hepatitis B patients, CNP was expressed in most of HBV-infected hepatocytes of liver specimens. Knockdown of CNP expression moderately improved viral production in the HepG2.2.15 cells treated with IFN-α. In conclusion, CNP might be a mediator of interferon-induced response against HBV. 相似文献

Fossil invertebrates collected or received by Alcide d’Orbigny, all his life long, have been brought together in a renowned collection that is very rich in terms of both species and specimens. The collection has resulted from a huge palaeontological work. Study of faunas from numerous French sites led Alcide d’Orbigny to do biostratigraphical comparisons and to erect geological stages, the definitions of which rest on their stratotypes. His wide knowledge of European fossil faunas was strengthened by a more global palaeobiogeographical view derived from his travel in South America. The d’Orbigny collection is housed in the ‘Muséum’ of Paris and is often visited by experts. 相似文献

The objective of this paper is the structural and narrative reconstruction of representations of ‘nature’, ‘wildlife’ and
‘landscape’, held by rural residents of the Dadia Forest Reserve. Data collection involved in-depth interviews. Employing
a social representations’ approach, we recovered representational elements that are expected in the case of rural belief systems,
such as negative dispositions towards wolves and foxes, as well as elements of an urban adherence, such as nature’s independence.
Representational elements refer to visual aspects of the countryside, which seem compatible with the figurative nucleus of
the rural idyll. Concerning ‘wildlife’, residents focused on vultures, which comprise the main tourist attraction of the reserve.
Scientific knowledge adds to the complexity of the narrative schema, which corresponds to the representation of ‘wildlife’.
Interviewees perceived the rural landscape as an interface between the natural and the human-conditioned environment. Our
study shows that interviewees make no reference to environmental conservation or quality of life issues, as it could be expected
according to relatively wide definitions of the term ‘environmentalism’. Environmental messages reinforced by ecotourism development
seem to be recalled primarily in terms of their compatibility with the perceived economic benefit of local people. Despite
ecotourism development, representational elements that diverge from a tourist version of ‘nature’, ‘wildlife’ and ‘landscape’
were not pronounced within rural belief-systems. Further interventions within the study area are needed, in order to address
a variety of topics under the environmental conservation discourse and raise the environmental awareness of rural residents. 相似文献
