Liability for wilful misconduct in the familiar relations
2016
La posible aplicación del art. 1.902 C.c. español para indemnizar los daños entre familiares ha sido una cuestión muy discutida. En los últimos quince años los Tribunales españoles se han enfrentado a un novedoso grupo de casos, el de los daños derivados de la ocultación de la verdadera paternidad biológica, concediendo indemnización y dando así entrada a la responsabilidad civil en el ámbito de las relaciones familiares, exigiendo, en la mayoría de las ocasiones, la culpa grave o el dolo como criterio de imputación. The possible application of the article 1.902 Spanish Civil Code to compensate the damages between relatives has been a very controversial question. In the last fifteen years t…
Stimulation of Spermatogenesis and Biological Paternity by Intranasal (Low Dose) Gonadotropin-Releasing Hormone (GnRH) in a Male with Kallmann's Synd…
1987
Intranasal (in) GnRH spray caused induction and maintenance of spermatogenesis and biological paternity in a 28-yr-old man with Kallmann's syndrome. Prior treatment had included GnRH analog administration, which failed to induce puberty, and testosterone (T) enanthate weekly. Prior hCG/human menopausal gonadotropin therapy had resulted in high normal serum T levels and near-normal semen quality, but during subsequent hCG therapy, spermatogenesis markedly decreased. The patient had then received 250 mg T enanthate/month for 2 yr and 7 months; it was discontinued 7 weeks before the in GnRH study began. At its start (July 1984) the subject's testis size was 7 mL, and he had azoospermia, low se…
Sexual Function, Social Integration and Paternity of Males with Classic Bladder Exstrophy following Urinary Diversion.
2015
We evaluated patients with classic bladder exstrophy and a history of urinary diversion for sexual function, social integration and paternity.We reviewed the medical records of males older than 18 years with exstrophy who had undergone urinary diversion at our department between 1969 and 2014. Patients were invited for structured followup examinations and were asked to complete questionnaires relating to sexual function, social integration and paternity.Of 79 eligible patients 39 (49%) with a mean followup of 23.8 years (range 2 to 45) were included in the study. Of the patients 41% had undergone primary urinary diversion and 59% had undergone secondary urinary diversion after failed recons…
A multiplex assay with 52 single nucleotide polymorphisms for human identification.
2006
A total of 52 SNPs reported to be polymorphic in European, Asian and African populations were selected. Of these, 42 were from the distal regions of each autosome (except chromosome 19). Nearly all selected SNPs were located at least 100 kb distant from known genes and commonly used STRs. We established a highly sensitive and reproducible SNP-typing method with amplification of all 52 DNA fragments in one PCR reaction followed by detection of the SNPs with two single base extension reactions analysed using CE. The amplicons ranged from 59 to 115 bp in length. Complete SNP profiles were obtained from 500 pg DNA. The 52 loci were efficiently amplified from degraded samples where previously on…
Ocean acidification affects fish spawning but not paternity at CO2 seeps
2016
Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO2 levels. Despite the higher r…
Pseudo-exclusion from paternity due to maternal uniparental disomy 16.
1998
The investigation of a case of disputed paternity revealed indirect exclusion of the alleged father in the haptoglobin system and in the DNA single-locus system D16S309/Hinf I (MS205). The paternity index for the non-exclusion systems was > 10(6). Since both exclusion systems (HP and MS205) are located on chromosome 16, we investigated 10 microsatellite loci covering this chromosome with 10-20 cM resolution. Analysis of the child's chromosome showed only alleles of maternal origin and lack of inheritance of paternal alleles for five informative loci. The markers close to the centromere of chromosome 16 were heterozygous, whereas distal loci were either heterozygous or homozygous for materna…
Forensics of birds of prey by DNA fingerprinting with 32P-labeled oligonucleotide probes.
1991
Paternity tests on confiscated families of eight species of birds of prey were carried out successfully by DNA fingerprinting with 32P-labeled oligonucleotide probes. Variations in the number of hybridized fragments, depending on the species of birds, are observed using the same probe, as well as differences of polymorphism by hybridizing the DNA samples with several oligonucleotide probes.
Biostatistical basis of individualization and segregation analysis using the multilocus DNA probe MZ 1.3: results of a collaborative study.
1992
A collaborative study using the multilocus minisatellite DNA probe MZ 1.3 was carried out to investigate segregation information, mutation rate, DNA fragment frequencies as well as band sharing characteristics. The fingerprint patterns of 393 children as well as 694 unrelated individuals were analysed after digestion of DNA with the restriction enzyme HinfI. A mutation rate of 1% per meiosis or 0.04% per band was found with a mean number of 26 bands/individual. It was shown that maternal and paternal fragments are inherited in equal proportions. Population frequencies of restriction fragments demonstrated a distribution with increasing frequencies in the small fragment size range below 10 k…
Females tend to prefer genetically similar mates in an island population of house sparrows.
2014
11 pages; International audience; BACKGROUND: It is often proposed that females should select genetically dissimilar mates to maximize offspring genetic diversity and avoid inbreeding. Several recent studies have provided mixed evidence, however, and in some instances females seem to prefer genetically similar males. A preference for genetically similar mates can be adaptive if outbreeding depression is more harmful than inbreeding depression or if females gain inclusive fitness benefits by mating with close kin. Here, we investigated genetic compatibility and mating patterns in an insular population of house sparrow (Passer domesticus), over a three-year period, using 12 microsatellite mar…
