Risk of childhood leukaemia and non-Hodgkin's lymphoma after parental occupational exposure to solvents and other agents: the SETIL Study
2013
AIM: In the context of the Italian Multicentric Epidemiological Study on Risk Factors for Childhood Leukaemia and Non-Hodgkin's Lymphoma (SETIL), the risk of childhood cancer was investigated in relation to parental occupational exposures. METHODS: All cases of childhood leukaemia and non-Hodgkin's lymphoma (NHL) in children aged 0-10 years were identified. Controls were chosen at random from the local population in each region. Parents were interviewed using a structured questionnaire. The collected data were blindly reviewed by expert industrial hygienists in order to estimate exposure to a list of agents. Statistical analyses were performed for each agent using unconditional multivariabl…
Expert witness in paternity testing in Germany.
2003
In Germany, paternity testing can be ordered by a judge as well as by private persons. In the case of private counselling, the expert has the duty to inform the parties on all medical, legal and ethical aspects. Informed consent must be given by each individual included in an exploration of family relationships. Due to the rapid progress of DNA typing in even minute amounts after polymerase chain reaction amplification, genotypes of short tandem repeat systems can be elicited by extraction from single cells. Therefore, the number of unlawful investigations of paternal relationships is steadily increasing. Here the requirements for paternity testing laboratories and sanctions for unlawful ex…
Tracking paternal genes with DALP markers in a pseudoarrhenotokous reproductive system: biparental transmission but haplodiploid-like inheritance in …
2000
International audience; The complexity of some sexual reproductive systems in arthropods still leaves both their genetic and epigenetic determinism and their evolutionary significance poorly understood. Pseudoarrhenotoky is characterized by obligate fertilization and differential inactivation and/or elimination of paternal chromosomes in embryos that develop into males. Here, we investigate how the paternal genome is transmitted in a pseudoarrhenotokous mite, Neoseiulus californicus, using codominant genetic markers detected by DALP (direct amplification of length polymorphism). Transmission patterns of parental alleles through one and two generations are reported at four or five loci corre…
Parental occupational exposure to endocrine disrupting chemicals and male genital malformations: a study in the Danish National Birth Cohort study
2011
Abstract Background Sex hormones closely regulate development of the male genital organs during fetal life. The hypothesis that xenobiotics may disrupt endogenous hormonal signalling has received considerable scientific attention, but human evidence is scarce. Objectives We analyse occurrence of hypospadias and cryptorchidism according to maternal and paternal occupational exposure to possible endocrine disrupting chemicals. Methods We conducted a follow-up study of 45,341 male singleton deliveries in the Danish National Birth Cohort during 1997-2009. Information on work during pregnancy was obtained by telephone interviews around gestational week 16. Parents' job titles were classified acc…
DXYS156: a multi-purpose short tandem repeat locus for determination of sex, paternal and maternal geographic origins and DNA fingerprinting
2002
In forensic science and in legal medicine Y chromosomal typing is indispensable for sex determination, for paternity testing in the absence of the father and for distinguishing males in multiple rape cases. Another potential application is the estimation of paternal geographic origin or family name from a crime stain to narrow down the range of suspects and thus reduce costs of mass screenings. However, Y typing alone cannot provide a sufficiently resolved DNA fingerprint as required for court convictions. Thus, there is a dilemma whether or not to sacrifice valuable material for the sake of extensive Y chromosomal investigations when stain DNA is limited (typically allowing only few PCR am…
Aposematism facilitates the diversification of parental care strategies in poison frogs
2021
AbstractMany organisms have evolved adaptations to increase the odds of survival of their offspring. Parental care has evolved several times in animals including ectotherms. In amphibians, ~ 10% of species exhibit parental care. Among these, poison frogs (Dendrobatidae) are well-known for their extensive care, which includes egg guarding, larval transport, and specialized tadpole provisioning with trophic eggs. At least one third of dendrobatids displaying aposematism by exhibiting warning coloration that informs potential predators about the presence of defensive skin toxins. Aposematism has a central role in poison frog diversification, including diet specialization, and visual and acoust…
Communication skills in medicine: where do we come from and where are we going?
2015
The physician-patient relationship has changed throughout history, as the role of physician has been transformed. Modern physicians need to be educated on how to use highly specialized knowledge when approaching the patient as a unique and whole person living in a given psychological, social, and material context. This relationship evolved from a paternalistic model to a cooperative-deliberative one, representing a meeting between two “experts:” the physician as the medical expert and the patient as the expert on himself. According to this model, communication between patients and physicians must be based on common understanding in a caring and dynamic relationship that also involves the pa…
Brief an Karl Axel Christer Freiherr von Bruiningk

Ms. 930a, Nr. 6b, Bl. 19r-19v Merkel, Garlieb H. Brief an Karl Axel Christer Freiherr von Bruiningk, [Depkinshof ?], [bez datuma; ohne Datum, pēc / nach 1839] Autora rokraksts / Autograph, vācu val. / Deutsch, [2] lpp. / S. Attēlu numuri / Bildnummern: 930a-006b-1 – 930a-006b-2 In dem undatierten Entwurf einer Antwort auf einen Brief Bruiningks [womit der unter Ms. 930a, Nr. 6a gemeint wird, bleibt noch unklar] lobt Merkel dessen Einsatz für die Bauernbefreiung. Das Problem des fehlenden Grundbesitzes für die freigelassenen Bauern sei ein Grund für die wirtschaftliche Rückständigkeit der „vaterländische[n] Provinzen“. Selbst in Posen (Preußen) und Galizien (Österreich) hätte die wirtschaftl…
Parent-Child Physical Resemblance as Cues of Man’s Paternity
2019
The article presents the hypothesis that in the formation of judgements about a man’s biological fatherhood based on similarity of physical characteristics, people may take into consideration not only the similarity of father to child, but also of mother to child. The objective of the experiment was to conduct an initial investigation of that assumption. In the experiment, participants were presented with descriptions in which information was manipulated concerning the similarity of child to mother vs. to father vs. to neither of them. A total of 312 students of both sexes took participation in the experiment, having agreed to take part in a short psychological study immediately after class…
El estilo parental transformacional, el apoyo a la autonomía y sus implicaciones en el burnout de deportistas adolescentes
2019
ABSTRACT The aim of this research was to examine the relationships between transformational parenting, autonomy support displayed by mothers and fathers, and sport burnout in 360 junior soccer players (324 males, range age = 12-18 years). To this end, four steps were followed. Steps 1 and 2 tested the psychometric properties (i.e., factorial structure, internal consistency, and evidence of discriminant validity) of the Spanish version of the Transformational Parenting Questionnaire (TPQ), and steps 3 and 4 examined the proposed relationships. Overall, the Spanish TPQ demonstrated adequate factorial validity and satisfactory internal consistency, representing a valid and reliable adaptation …
