International audience; Both in the U.S. and in France, inheritance is probably the main factor of wealth concentration among the richest part of the population, and of its intergenerational reproduction. In so far as wealth is an opportunity, a reform of inheritance tax could be a mean to ensure a fairer distribution of opportunities in the society. Many reforms of inheritance systems have been conceived at least since Bentham. The identification and the analysis of ethical properties of ref...

Inherited factor VII (FVII) deficiency is a rare recessive inherited coagulation disorder with limited available information, especially in patients undergoing major thoracic surgery. In addition, an optimal management strategy for the disease has not been defined. We herein report a case involving a 61-year-old man with asymptomatic FVII deficiency who underwent a right middle and lower lobectomy to treat lung cancer. To the best of our knowledge, the present report is the first to describe the use of recombinant activated FVII continuous infusion for bleeding control after a major thoracic surgery in a patient with inherited FVII deficiency.

Intracranial hemorrhage (ICH) is a medical emergency. In congenital bleeding disorders, ICH is a devastating presentation accompanied with a high rate of morbidity and mortality. The prevalence of ICH is highly variable among congenital bleeding disorders, with the highest incidence observed in factor (F) XIII deficiency (FXIIID) (∼30%). This life-threatening presentation is less common in afibrinogenemia, FVIII, FIX, FVII, and FX deficiencies, and is rare in severe FV and FII deficiencies, type 3 von Willebrand disease and inherited platelet function disorders (IPFDs). In FXIIID, this diathesis most often occurs after trauma in children, whereas spontaneous ICH is more frequent in adults. About 15% of patients with FXIIID and ICH die; the bleeding causes 80% of deaths in this coagulopathy. Although in FXIIID, the bleed most commonly is intraparenchymal (> 90%), epidural, subdural, and subarachnoid hemorrhages also have been reported, albeit rarely. As this life-threatening bleeding causes neurological complications, early diagnosis can prevent further expansion of the hematoma and secondary damage. Neuroimaging plays a crucial role in the diagnosis of ICH, but signs and symptoms in patients with severe FXIIID should trigger replacement therapy even before establishment of the diagnosis. Although a high dose of FXIII concentrate can reduce the rate of morbidity and mortality of ICH in FXIIID, it may occasionally trigger inhibitor development, thus complicating ICH management and future prophylaxis. Nevertheless, replacement therapy is the mainstay of treatment for ICH in FXIIID. Neurosurgery is performed in patients with FXIIID and epidural hematoma and a hemorrhage diameter exceeding 2 cm or a volume of ICH is more than 30 cm 3 . Contact sports are not recommended in people with FXIIID as they can elicit ICH. However, a considerable number of safe sports and activities have been suggested to have more benefits than dangers for patients with congenital bleeding

Characterization of carbonic anhydrase XIII in the erythrocytes of the Burmese python, Python molurus bivittatus.

Carbonic anhydrase (CA) is one of the most abundant proteins found in vertebrate erythrocytes with the majority of species expressing a low activity CA I and high activity CA II. However, several phylogenetic gaps remain in our understanding of the expansion of cytoplasmic CA in vertebrate erythrocytes. In particular, very little is known about isoforms from reptiles. The current study sought to characterize the erythrocyte isoforms from two squamate species, Python molurus and Nerodia rhombifer, which was combined with information from recent genome projects to address this important phylogenetic gap. Obtained sequences grouped closely with CA XIII in phylogenetic analyses. CA II mRNA transcripts were also found in erythrocytes, but found at less than half the levels of CA XIII. Structural analysis suggested similar biochemical activity as the respective mammalian isoforms, with CA XIII being a low activity isoform. Biochemical characterization verified that the majority of CA activity in the erythrocytes was due to a high activity CA II-like isoform; however, titration with copper supported the presence of two CA pools. The CA II-like pool accounted for 90 % of the total activity. To assess potential disparate roles of these isoforms a feeding stress was used to up-regulate CO2 excretion pathways. Significant up-regulation of CA II and the anion exchanger was observed; CA XIII was strongly down-regulated. While these results do not provide insight into the role of CA XIII in the erythrocytes, they do suggest that the presence of two isoforms is not simply a case of physiological redundancy.

Background Plasma-derived factor XIII (FXIII) concentrate is an effective treatment for FXIII deficiency. We describe adverse drug reactions (ADRs) reported during pharmacovigilance monitoring of Fibrogammin®/Corifact® and review published safety data. Methods Postmarketing safety reports recorded by CSL Behring from June 1993 to September 2013 were analyzed. Clinical studies published during the same period were also reviewed. Results Commercial data indicated that 1,653,450,333 IU FXIII concentrate were distributed over the review period, equivalent to 1,181,036 doses for a 70 kg patient. 75 cases were reported (one/15,700 standard doses or 22,046,000 IU). Reports of special interest included 12 cases of possible hypersensitivity reactions (one/98,400 doses or 137,787,500 IU), 7 with possible thromboembolic events (one/168,700 doses or 236,207,200 IU), 5 of possible inhibitor development (one/236,200 doses or 330,690,100 IU), and 20 of possible pathogen transmission (one/59,100 doses or 82,672,500 IU). 19 pathogen transmission cases involved viral infection; 4 could not be analyzed due to insufficient data, but for all others a causal relationship to the product was assessed as unlikely. A review of published literature revealed a similar safety profile. Conclusion Assessment of ADRs demonstrated that FXIII concentrate carries a low risk of ADRs across various clinical situations, suggesting a favorable safety profile. PMID:27781024

Elusive inheritance: Transgenerational effects and epigenetic inheritance in human environmental disease.

Science.gov (United States)

Martos, Suzanne N; Tang, Wan-Yee; Wang, Zhibin

2015-07-01

Epigenetic mechanisms involving DNA methylation, histone modification, histone variants and nucleosome positioning, and noncoding RNAs regulate cell-, tissue-, and developmental stage-specific gene expression by influencing chromatin structure and modulating interactions between proteins and DNA. Epigenetic marks are mitotically inherited in somatic cells and may be altered in response to internal and external stimuli. The idea that environment-induced epigenetic changes in mammals could be inherited through the germline, independent of genetic mechanisms, has stimulated much debate. Many experimental models have been designed to interrogate the possibility of transgenerational epigenetic inheritance and provide insight into how environmental exposures influence phenotypes over multiple generations in the absence of any apparent genetic mutation. Unexpected molecular evidence has forced us to reevaluate not only our understanding of the plasticity and heritability of epigenetic factors, but of the stability of the genome as well. Recent reviews have described the difference between transgenerational and intergenerational effects; the two major epigenetic reprogramming events in the mammalian lifecycle; these two events making transgenerational epigenetic inheritance of environment-induced perturbations rare, if at all possible, in mammals; and mechanisms of transgenerational epigenetic inheritance in non-mammalian eukaryotic organisms. This paper briefly introduces these topics and mainly focuses on (1) transgenerational phenotypes and epigenetic effects in mammals, (2) environment-induced intergenerational epigenetic effects, and (3) the inherent difficulties in establishing a role for epigenetic inheritance in human environmental disease.

León XIII y la memoria de un catolicismo que «nació libre»

Directory of Open Access Journals (Sweden)

Robles Muñoz, Cristóbal

2004-06-01

Full Text Available Problems and responses during the pontificate of León XIII experienced changes of orientation after arrival of Pío XII. One of the problems was how to extend the presence of the Church among society, and expand relations of the latest with the Church. Responses were freedom and justice. Freedom to reflect on faith, thinking over its origins and dialoguing with culture, and to use recognised civil rights. Justice as a moral compromise towards the inhuman life conditions suffered by the population. León XIII was frightened at any innovation, but accepted the debate.

Los problemas y respuestas presentes en la etapa de León XIII experimentaron un cambio de rumbo con la llegada de Pío X. Los problemas enraízan la presencia de la Iglesia en la sociedad y de ésta en la Iglesia. Las respuestas, la libertad y la justicia. La libertad, para pensar la fe, investigando sus orígenes y dialogando con la cultura, para usar derechos civilmente reconocidos. La justicia, como exigencia moral frente a las condiciones inhumanas en las que vive el pueblo. León XIII temió las novedades, pero aceptó el debate.

Evaluating Factor XIII Specificity for Glutamine-Containing Substrates Using a MALDI-TOF Mass Spectrometry Assay

Science.gov (United States)

Doiphode, Prakash G.; Malovichko, Marina V.; Mouapi, Kelly Njine; Maurer, Muriel C.

2014-01-01

Activated Factor XIII (FXIIIa) catalyzes the formation of γ-glutamyl-ε-lysyl cross-links within the fibrin blood clot network. Although several cross-linking targets have been identified, the characteristic features that define FXIIIa substrate specificity are not well understood. To learn more about how FXIIIa selects its targets, a matrix-assisted laser desorption ionization – time of flight mass spectrometry (MALDI-TOF MS) based assay was developed that could directly follow the consumption of a glutamine-containing substrate and the formation of a cross-linked product with glycine ethylester. This FXIIIa kinetics assay is no longer reliant on a secondary coupled reaction, on substrate labeling, or on detecting the final deacylation portion of the transglutaminase reaction. With the MALDI-TOF MS assay, glutamine-containing peptides derived from α2-antiplasmin, S. Aureus fibronectin binding protein A, and thrombin activatable fibrinolysis inhibitor were examined directly. Results suggest that the FXIIIa active site surface responds to changes in substrate residues following the reactive glutamine. The P-1 substrate position is sensitive to charge character and the P-2 and P-3 to the broad FXIIIa substrate specificity pockets. The more distant P-8 to P-11 region serves as a secondary substrate anchoring point. New knowledge on FXIIIa specificity may be used to design better substrates or inhibitors of this transglutaminase. PMID:24751466

To establish the cellular source of plasma factor (F)XIII-A. A novel mouse floxed for the F13a1 gene, FXIII-A flox/flox (Flox), was crossed with myeloid- and platelet-cre-expressing mice, and cellular FXIII-A mRNA expression and plasma and platelet FXIII-A levels were measured. The platelet factor 4-cre.Flox cross abolished platelet FXIII-A and reduced plasma FXIII-A to 23±3% ( P cre on plasma FXIII-A was exerted outside of the megakaryocyte lineage because plasma FXIII-A was not reduced in the Mpl -/- mouse, despite marked thrombocytopenia. In support of this, platelet factor 4-cre depleted FXIII-A mRNA in brain, aorta, and heart of floxed mice, where FXIII-A pos cells were identified as macrophages as they costained with CD163. In the integrin αM-cre.Flox and the double copy lysozyme 2-cre.cre.Flox crosses, plasma FXIII-A was reduced to, respectively, 75±5% ( P =0.003) and 30±7% ( P <0.001), with no change in FXIII-A content per platelet, further consistent with a macrophage origin of plasma FXIII-A. The change in plasma FXIII-A levels across the various mouse genotypes mirrored the change in FXIII-A mRNA expression in aorta. Bone marrow transplantation of FXIII-A +/+ bone marrow into FXIII-A -/- mice both restored plasma FXIII-A to normal levels and replaced aortic and cardiac FXIII-A mRNA, while its transplantation into FXIII-A +/+ mice did not increase plasma FXIII-A levels, suggesting that a limited population of niches exists that support FXIII-A-releasing cells. This work suggests that resident macrophages maintain plasma FXIII-A and exclude the platelet lineage as a major contributor. © 2017 The Authors.

Immune responses to influenza virus and its correlation to age and inherited factors

Full Text Available Influenza viruses belong to the family Orthomyxoviridae of enveloped viruses and are an important cause of respiratory infections worldwide. The influenza virus is able to infect a wide variety species as diverse as poultry, marine, pigs, horses and humans. Upon infection with influenza virus the innate immunity plays a critical role in efficient and rapid control of viral infections as well as in adaptive immunity initiation. The humoral immune system produces antibodies against different influenza antigens, of which the HA-specific antibody is the most important for neutralization of the virus and thus prevention of illness. Cell mediated immunity including CD4+ helper T cells and CD8+ cytotoxic T cells are the other arms of adaptive immunity induced upon influenza virus infection. The complex inherited factors and age related changes are associated with the host immune responses. Here, we review the different components of immune responses against influenza virus. Additionally, the correlation of the immune response to age and inherited factors has been discussed. These determinations lead to a better understanding of the limitations of immune responses for developing improved vaccines to control influenza virus infection.

Classical elements in the endowments of Serbian XIII century donors

Full Text Available In Byzantine painting, starting from the XIII and particularly during the XIV century, there was a visible return to models from the period of Antiquity. The influences of ancient, ostensibly, Hellenistic heritage were reflected in the shapes, in the content of the compositions, as well as in the drawing, modellation and colours. In the art that came into being in the course of the XIII century, in the endowments of the Serbian donors numerous elements emerged that had existed in ancient art. In the frescoes in the Church of the Mother of God in Studenica, the endowment of Stefan Nemanja and his sons, we see personifications, symbols, the introduction of details, and space acquiring depth, features that were later to come to full expression, especially from the middle of the XIII century. The few preserved frescoes dating from the XIII century in the Church of the Resurrection in the Žiča monastery, the endowment of Stefan the First Crowned, his son Radoslav and his brother Sava, are an iconographic continuation of the trends in the art one encounters in Studenica. The frescoes in the Church of Christ's Ascension in Mileševa, the endowment of King Vladislav, with their subtly fashioned figures and carefully modelled faces, as well as refined colouring, signal a return to the Hellenistic models. The painting in the Church of Dormition of the Virgin in the Morača monastery, the endowment of Prince Stefan, nephew of king Stefan, with its well-proportioned, firmly modelled figures, landscapes and architecture deepening the space, reminds one of the Sopoćani frescoes. In the fresco painting of the Holy Apostles in Peć, the endowment of Archbishop Sava which owed its outcome to the efforts of Archbishop Arsenije I, the images are very vivid, and the painted architecture is depicted in an abbreviated form, using different kinds of perspective. The painting in the Church of the Holy Trinity in Sopoćani, the endowment of king Uroš I, represents

The relative importance of inheritances in Norway

Johansson, Marianne Lefsaker

2014-01-01

In a very influential paper, Piketty (2011) finds that inherited wealth is of increasing importance in France. He describes a U-shaped pattern in the long-run development of inheritance flows. Two driving factors in this development are the relative ratio of wealth of the deceased to wealth of the living, and the wealth-income ratio. In periods with high economic growth, wealth of the past is weakened and inheritances as share of national income decreases. As soon as growth declines, however,...

Osteosarcoma inheritance in two families of Scottish deerhounds.

Science.gov (United States)

Dillberger, John E; McAtee, Sara Ann

2017-01-01

Osteosarcoma is the most common neoplastic disease in Scottish Deerhounds. For Deerhounds, a 2007 population-based study concluded that a single dominant genetic factor largely governed disease risk. For Greyhounds, Rottweilers, and Irish Wolfhounds, a 2013 genome-wide association study found multiple genetic markers in each breed, with each marker only weakly associated with the disease. We obtained from two breeders the pedigrees, age (if alive) or age at death, and osteosarcoma status for two families of Scottish Deerhounds, designated Cohorts K and T. A dog was considered unaffected only if it was osteosarcoma-free and at least 8.5 years old. We analyzed the data in two ways, by assuming either a single recessive genetic factor or a single dominant genetic factor with high penetrance. Cohort K contained 54 evaluable dogs representing 12 litters. Cohort T contained 56 evaluable dogs representing eight litters. Osteosarcoma seemed clearly heritable in both cohorts; however, having a parent with osteosarcoma raised a pup's risk of developing osteosarcoma to 38% for Cohort K but 78% for Cohort T, suggesting the possibility of different genetic risk factors in each cohort. In Cohort K, osteosarcoma inheritance fit well with a single, recessive, autosomal risk factor, although we could not rule out the possibility of a single dominant risk factor with incomplete penetrance. In Cohort T, inheritance could be explained well by a single, dominant, autosomal risk factor but was inconsistent with recessive expression. Inheritance of osteosarcoma in two Scottish Deerhound families could be explained well by a single genetic risk factor residing on an autosome, consistent with a 2007 report. In one family, inheritance was consistent with dominant expression, as previously reported. In the other family, inheritance fit better with recessive expression, although the possibility of a dominant genetic factor influenced by one or more other genetic factors could not be ruled

The RUNX1 (AML1, CBFA2) gene is a member of the runt transcription factor family, responsible for DNA binding and heterodimerization of other non-DNA binding transcription factors. RUNX1 plays an important part in regulating haematopoiesis and it is frequently disrupted by illegitimate somatic recombination in both acute myeloid and lymphoblastic leukaemia. Germline mutations of RUNX1 have also recently been described and are dominantly associated with inherited leukaemic conditions. We have identified a unique point mutation of the RUNX1 gene (A107P) in members of a family with autosomal dominant inheritance of thrombocytopenia. One member has developed acute myeloid leukaemia (AML).

Inheritance of tristyly in Oxalis tuberosa (Oxalidaceae).

Trognitz, B R; Hermann, M

2001-05-01

Frequencies of floral morphs in progenies obtained from a complete set of diallelic crosses among three accessions of tristylous, octoploid oca (Oxalis tuberosa) were used for a Mendelian analysis of floral morph inheritance. The frequencies observed had the best fit to a model of tetrasomic inheritance with two diallelic factors, S, s and M, m, with S being epistatic over M. No explanation could be found for the unexpected formation of a small percentage of short-styled individuals in crosses between the mid-styled and the long-styled parent. For the acceptance of models of disomic and octosomic inheritance several additional assumptions would have to be made and therefore these modes of inheritance are less likely. Dosage-dependent inheritance of floral morph was rejected. Only a small frequency (36%) of the cross progenies flowered, in contrast to the greater propensity for flowering of O. tuberosa accessions held at gene banks.

Full Text Available The article examines the approaches of the Russian press (“Moskovskie Vedomosti”, “Russkie Vedomosti”, “Novoe Vremia” to the evaluation of the Spanish King Alfonso XIII (1886–1941 at the first stage of his government. During this time he, acting within the powers granted to him by the Spanish constitution of the Restoration era, tried to stabilize the political situation in Spain and raise the prestige of the royal power, is also actively involved in social and political life of the country. Alfonso XIII also sought to raise the country's prestige in the international arena, seriously shaken after the “disaster in 1898”. The special attention is paid to the problem of formation of public opinion by the Russian press, on the example of newspaper coverage of humanitarian and intermediate activity of the Spanish king during the First World War. The activity of Alfonso XIII, aimed at protecting the interests of the citizens of the Russian Empire and the Slavic population of Austria-Hungary, in particular, his personal involvement in the rescue of the Austrian authorities was sentenced to death by a correspondent of the newspaper "New time" in Vienna D.G. Yanchevetskiy, forced the Russian public during the war to change the attitude towards Spain, its king and Spanish neutrality.

On the basis of systematicly reviewing the developmental history of acupuncture and moxibustion and profoundly understanding its academic connotations, the authors of the present article make a summary and analysis on the key factors influencing the development of acupuncturology. These key factors are (1) the emergence of "microacupuncture needle regulating-Qi" and the establishement of their corresponding theory system, (2) a large number of practitioners who inherited the learnings of acupuncturology generations by generations, and abundant medical classical works which recorded the valuable academic thoughts and clinical experience of the predecesors, (3) the application of acupuncture charts and manikins, and (4) modernizing changes of acupuncture learnings after introduction of western medicine to China. Just under the influence of these key factors, the acupuncture medicine separates itself from the level of the simple experience medicine, and has formed a set of special theory system and developed into a mature subject.

To inherit heritage or to inherit inheritance?

Full Text Available The Republic of Serbia is one of the few, if not the only country in the world that, at ratification and translation of the term „baština“– heritage which appears in two significant and related international conventions of UNESCO, used different terms: „baština“– „heritage“, with regard to the Convention Concerning the Protection of the World Cultural and Natural Heritage, and „nasledje“ –inheritance in the Convention for the Safeguarding of the Intangible Cultural Heritage. One of the reasons for the subsequent rejection of the term heritage could lay in the opinion that it was the case of (end of 20th and beginning of the 21st century political bureaucratic introduction of an old, forgotten word, which also contains the notion of gender incorrectness based on pointing out the inheritance through the male line, which could be in conflict with international law. The views expressed in this paper suggest the unsustainability of these claims, as well as greater suitability of the term „baština“– heritage. Namely, the ratification of the Convention Concerning the Protection of the World Cultural and Natural Heritage was done as early as in 1974, and since then the term „baština“– heritage was used, its new introduction into use on the basis of recent daily political aspirations cannot be the case. At the same time inheritance through the male line is encountered with the use of the Latin word „patrimonium“, which is the basis for the terms used in the official translation of the UNESCO-listed conventions in French and Spanish: „patrimoine“ and „patrimonio“ (and other Roman languages so that the use of the term „baština“ –heritage cannot be a violation of international legal norms. Finally, bearing in mind the fact that, in general, use of languages is impossible to achieve complete gender purism, it is necessary to emphasize that in contrast to the term „nasledje“ – inheritance, the

Recent research using fungi as models provide new insight into the ability of regulatory networks to generate cellular states that are sufficiently stable to be faithfully transmitted to daughter cells, thereby generating epigenetic inheritance. Such protein-based inheritance is driven by infectious factors endowed with properties usually displayed by prions. We emphasize the contribution of regulatory networks to the emerging properties displayed by cells.

Unexplained infertility represents one of the most common diagnoses in fertility care. Attention is being paid to the association between inherited thrombophilia and infertility causes. In this study we investigated the prevalence of inherited thrombophilia according to infertility causes. We studied Prothrombin gene G20210A mutation, Factor V Leiden, deficiencies in protein S and C and antithrombin in 930 Caucasian infertile women referred to Fertility Center of the Department of Sciences for Woman and Child's Health, University of Florence, of whom 230 with unexplained, 195 female and 283 male infertility, and in 240 women who have conceived naturally without hormonal stimulation therapy. A significant relationship between inherited thrombophilia [OR 95%CI 1.97 (1.05-3.68), p = 0.03] and unexplained infertility was observed, whereas no association between thrombophilia and female and male infertility was found. Significantly higher prevalence of prothrombin gene mutation in unexplained infertile women in comparison to that observed in fertile women was observed (5.7% vs 2.1% p = 0.04); the prevalence of the other thrombophilia determinants was higher, even if not significantly, in the unexplained infertile group. This study demonstrates the relationship between inherited thrombophilia and unexplained infertility, thus suggesting the contribution of genetic components in modulating unexplained infertility, behind anovulation, male and tubal factor.

Thrombosis is known to occur in patients with rare inherited bleeding disorders, usually in the presence of a thrombotic risk factor such as surgery and/or factor replacement therapy, but sometimes spontaneously. We present the case of a 72-year-old African American male diagnosed with congenital factor VII (FVII) deficiency after presenting with ischemic stroke, presumably embolic, in the setting of atherosclerotic carotid artery stenosis. The patient had an international normalized ratio (INR) of 2.0 at presentation, with FVII activity of 6% and normal Extem clotting time in rotational thromboelastometry. He was treated with aspirin (325 mg daily) and clopidogrel (75 mg daily) with no additional bleeding or thrombotic complications throughout his admission. This case provides further evidence that moderate to severe FVII deficiency does not protect against thrombosis. Copyright © 2016 Elsevier Ltd. All rights reserved.

Inherited factor VII (FVII) deficiency is one of the commonest rare bleeding disorders. It is characterized by a wide molecular and clinical heterogeneity and an autosomal recessive pattern of inheritance. Factor VII-deficient patients are still scarcely explored in Pakistan although rare bleeding disorders became quite common as a result of traditional consanguineous marriages. The aim of the study was to give a first insight of F7 gene mutations in Pakistani population. Ten unrelated FVII-deficient patients living in Pakistan were investigated (median FVII:C = 2%; range = 2-37%). A clinical questionnaire was filled out for each patient and direct sequencing was performed on the coding regions, intron/exon boundaries and 5' and 3' untranslated regions of the F7 gene. Nine different mutations (eight missense mutations and one located within the F7 promoter) were identified on the F7 gene. Five of them were novel (p.Cys82Tyr, p.Cys322Ser, p.Leu357Phe, p.Thr410Ala, c-57C>T, the last being predicted to alter the binding site of transcription factor HNF-4). Half of the patients had single mutations in Cys residues involved in disulfide bridges. The p.Cys82Arg mutation was the most frequent in our series. Six of seven patients with FVII:C levels below 10% were homozygous in connection with the high percentage of consanguinity in our series. In addition, we graded the 10 patients according to three previously published classifications for rare bleeding disorders. The use of the bleeding score proposed by Tosetto and co-workers in 2006 appears to well qualify the bleeding tendency in our series. © 2013 John Wiley & Sons Ltd.

The mechanism that initiates the onset of puberty is largely unknown but the age of onset is mainly under genetic control and influenced by environmental factors including nutrition. Familial forms of constitutional delay of puberty (CDP) suggest the involvement of genetic factors. The purpose of this study is to describe the presentation and the mode of inheritance of CDP in a series of familial cases. A retrospective, single center study was carried out over 10 years on 48 probands (14 girls and 34 boys) from 48 families seen for CDP with a familial component. Of the 48 probands, 46 (96 %) had at least one affected 1(st) degree relatives and 2 (4 %, 2 boys) had only 2(nd) degree relatives affected. In girls, 11 families (79 %) exhibited exclusive maternal inheritance, 1 (7 %) paternal inheritance and 2 (14 %) both maternal and paternal inheritance. In boys, 14 families (41 %) exhibited exclusive maternal inheritance, 12 (35 %) paternal inheritance and 8 (24 %) both maternal and paternal inheritance. In the boys with bilineal inheritance, the ages at onset of puberty (16 ± 1.41 years) and at evaluation (16.05 ± 2.47 years) were higher than in those with unilineal inheritance (15.25 ± 0.35 and 15.1 ± 0.42 years respectively), but the difference was not significant. In girls exclusive maternal inheritance seems to be the major mode of inheritance whereas for boys the mode of inheritance was almost equally maternal, paternal or bilineal. Clinical phenotype of boys with bilineal inheritance seems to be more severe, but the difference did not reach statistical significance, perhaps because of the small sample size. This greater severity of the phenotype in boys with bilineal inheritance is likely due to inheriting different puberty timing genes from each parent. Future research should be directed at identifying such genes.

Telomeres are emerging as a biomarker for ageing and survival, and are likely important in shaping life-history trade-offs. In particular, telomere length with which one starts in life has been linked to lifelong survival, suggesting that early telomere dynamics are somehow related to life-history trajectories. This result highlights the importance of determining the extent to which telomere length is inherited, as a crucial factor determining early life telomere length. Given the scarcity of species for which telomere length inheritance has been studied, it is pressing to assess the generality of telomere length inheritance patterns. Further, information on how this pattern changes over the course of growth in individuals living under natural conditions should provide some insight on the extent to which environmental constraints also shape telomere dynamics. To fill this gap partly, we followed telomere inheritance in a population of king penguins (Aptenodytes patagonicus). We tested for paternal and maternal influence on chick initial telomere length (10 days old after hatching), and how these relationships changed with chick age (at 70, 200 and 300 days old). Based on a correlative approach, offspring telomere length was positively associated with maternal telomere length early in life (at 10 days old). However, this relationship was not significant at older ages. These data suggest that telomere length in birds is maternally inherited. Nonetheless, the influence of environmental conditions during growth remained an important factor shaping telomere length, as the maternal link disappeared with chicks' age.

Massive traumatic haemorrhage is aggravated through the development of trauma-induced coagulopathy, which is managed by plasma transfusion and/or fibrinogen concentrate administration. It is yet unclear whether these treatments are equally potent in ensuring adequate haemostasis, and whether additional factor XIII (FXIII) administration provides further benefits. In this study, we compared ROTEM whole blood coagulation profiles after experimental massive transfusion with different transfusion regimens in an in vitro model of dilution- and transfusion-related coagulopathy. Healthy donor blood was mixed 1 + 1 with six different transfusion regimens. Each regimen contained RBC, platelet concentrate, and either fresh frozen plasma (FFP) or Ringer's acetate (RA). The regimens were further augmented through addition of a low- or medium-dose fibrinogen concentrate and FXIII. Transfusion with FFP alone was insufficient to maintain tissue-factor activated clot strength, coincidental with a deficiency in fibrin-based clot strength. Fibrinogen concentrate conserved, but did not improve coagulation kinetics and overall clot strength. Only combination therapy with FFP and low-dose fibrinogen concentrate improved both coagulation kinetics and fibrin-based clot strength. Administration of FXIII did not result in an improvement of clot strength. In conclusion, combination therapy with both FFP and low-dose fibrinogen concentrate improved clotting time and produced firm clots, representing a possible preferred first-line regimen to manage trauma-induced coagulopathy when RBC and platelets are also transfused. Further research is required to identify optimal first-line transfusion fluids for massive traumatic haemorrhage.

The role of inheritance in structuring hyperextended rift systems

Manatschal, Gianreto; Lavier, Luc; Chenin, Pauline

2015-04-01

A long-standing question in Earth Sciences is related to the importance of inheritance in controlling tectonic processes. In contrast to physical processes that are generally applicable, assessing the role of inheritance suffers from two major problems: firstly, it is difficult to appraise without having insights into the history of a geological system; and secondly all inherited features are not reactivated during subsequent deformation phases. Therefore, the aim of our presentation is to give some conceptual framework about how inheritance may control the architecture and evolution of hyperextended rift systems. We use the term inheritance to refer to the difference between an "ideal" layer-cake type lithosphere and a "real" lithosphere containing heterogeneities and we define 3 types of inheritance, namely structural, compositional and thermal inheritance. Moreover, we assume that the evolution of hyperextended rift systems reflects the interplay between their inheritance (innate/"genetic code") and the physical processes at play (acquired/external factors). Thus, by observing the architecture and evolution of hyperextended rift systems and integrating the physical processes, one my get hints on what may have been the original inheritance of a system. Using this approach, we focus on 3 well-studied rift systems that are the Alpine Tethys, Pyrenean-Bay of Biscay and Iberia-Newfoundland rift systems. For the studied examples we can show that: 1) strain localization on a local scale and during early stages of rifting is controlled by inherited structures and weaknesses 2) the architecture of the necking zone seems to be influenced by the distribution and importance of ductile layers during decoupled deformation and is consequently controlled by the thermal structure and/or the inherited composition of the curst 3) the location of breakup in the 3 examples is not significantly controlled by the inherited structures 4) inherited mantle composition and rift

Tactic "Tulgama" the Art of War the Mongols XIII century

Full Text Available In this publication, based on a comprehensive analysis of the sources, considered one of the most important tactics of the Mongols of the XIII century, known under the Turkic name "Tulgama". The name of the maneuver is derived from the Turkic verb "talamak", meaning "to surround, to wrapped up, to turn, to whirl, to twist". It is established that the maneuver "Tulgama" was a special tactic, providing coverage flank (flanks of the enemy in the rear and the application of massed archery shot in his builds. Selected three varieties under consideration tactic: right flank or left flank and steam room (double "Tulgama". The most typical was right flanks "Tulgama" when doing the nomads, covered the left wing of the enemy with its right flank. This allowed the attacking archers to fire from the most convenient position (left-forward, left, and left-back. A characteristic feature of the Mongol tactical art was a steam room (double "Tulgama" when the troops of nomads covered both enemy's flank, concluding the enemy's army in the ring, then attacked her from all four sides. A similar technique could not only shoot down from the position, but almost completely destroy the enemy troops. For the most efficient use of maneuver "Tulgama" the Mongols made increasing use of expanded mesalamines system, with a powerful thrust forward flank groups. The concentration of the shock troops on the flanks (reinforced, including by weakening the Central shelf is dramatically different from the tactics of the Mongols from the traditional tactics of the Turks, whose best part was typically the center of the combat formations. However, direct confrontation of these two approaches during the military campaigns of the XIII century demonstrated the advantages of the Mongol tactical schemes. High efficiency of reception "Tulgama" led to its continued existence in the military art of the nomads.

Atypical mitochondrial inheritance patterns in eukaryotes.

Science.gov (United States)

Breton, Sophie; Stewart, Donald T

2015-10-01

Mitochondrial DNA (mtDNA) is predominantly maternally inherited in eukaryotes. Diverse molecular mechanisms underlying the phenomenon of strict maternal inheritance (SMI) of mtDNA have been described, but the evolutionary forces responsible for its predominance in eukaryotes remain to be elucidated. Exceptions to SMI have been reported in diverse eukaryotic taxa, leading to the prediction that several distinct molecular mechanisms controlling mtDNA transmission are present among the eukaryotes. We propose that these mechanisms will be better understood by studying the deviations from the predominating pattern of SMI. This minireview summarizes studies on eukaryote species with unusual or rare mitochondrial inheritance patterns, i.e., other than the predominant SMI pattern, such as maternal inheritance of stable heteroplasmy, paternal leakage of mtDNA, biparental and strictly paternal inheritance, and doubly uniparental inheritance of mtDNA. The potential genes and mechanisms involved in controlling mitochondrial inheritance in these organisms are discussed. The linkage between mitochondrial inheritance and sex determination is also discussed, given that the atypical systems of mtDNA inheritance examined in this minireview are frequently found in organisms with uncommon sexual systems such as gynodioecy, monoecy, or andromonoecy. The potential of deviations from SMI for facilitating a better understanding of a number of fundamental questions in biology, such as the evolution of mtDNA inheritance, the coevolution of nuclear and mitochondrial genomes, and, perhaps, the role of mitochondria in sex determination, is considerable.

The information value of non-genetic inheritance in plants and animals.

Directory of Open Access Journals (Sweden)

Sinead English

Full Text Available Parents influence the development of their offspring in many ways beyond the transmission of DNA. This includes transfer of epigenetic states, nutrients, antibodies and hormones, and behavioural interactions after birth. While the evolutionary consequences of such non-genetic inheritance are increasingly well understood, less is known about how inheritance mechanisms evolve. Here, we present a simple but versatile model to explore the adaptive evolution of non-genetic inheritance. Our model is based on a switch mechanism that produces alternative phenotypes in response to different inputs, including genes and non-genetic factors transmitted from parents and the environment experienced during development. This framework shows how genetic and non-genetic inheritance mechanisms and environmental conditions can act as cues by carrying correlational information about future selective conditions. Differential use of these cues is manifested as different degrees of genetic, parental or environmental morph determination. We use this framework to evaluate the conditions favouring non-genetic inheritance, as opposed to genetic determination of phenotype or within-generation plasticity, by applying it to two putative examples of adaptive non-genetic inheritance: maternal effects on seed germination in plants and transgenerational phase shift in desert locusts. Our simulation models show how the adaptive value of non-genetic inheritance depends on its mechanism, the pace of environmental change, and life history characteristics.

To explore the characteristics of laboratory examination and confirm the diagnosis of a patient with combined inherited FVII and FX deficiency after he ingested diphacinone rodenticide accidentally. The coagulant parameter screening tests and coagulation factor activities were tested many times in the patient due to accidental ingestion of a diphacinone rodenticide. After the patient was treated for more than one year, gene analysis of correlated coagulation factors was analyzed in the patient and other family members by DNA direct sequencing. 106 persons were selected as controls from routine health examinations. After the patient was admitted to hospital, routine coagulation screening tests revealed the prolonged prothrombin time (PT) and activated partial thromboplastin time (APTT) and low levels of vitamin K-dependent coagulation factors (FII, FVII, FIX, FX) activity, which was 102.4 seconds, 88.5 seconds, 7%, 3%, 8%, and 2%, respectively. During more than one year of treatment, the value of PT and APTT still showed significantly prolonged activity and FVII and FX activity levels were about 5%. While FII and FIX activity levels were in the normal range after 12 weeks of treatment. Two homozygous mutations, g.11267C>T of F7 gene resulting in the substitution Arg277Cys and g.28139G>T of F10 gene leading to the substitution Val384Phe, were identified in the patient. The patient's parents and sister was heterozygous for Arg277Cys and Val384Phe mutations. FVII and FX antigen levels in the patient were 7% and 30%, respectively. There were many similarities in the characteristics of laboratory examination between combined inherited FVII and FX deficiency and acquired vitamin K deficiency. The best way to identify them was gene analysis.

Understanding aneuploidy in cancer through the lens of system inheritance, fuzzy inheritance and emergence of new genome systems.

Ye, Christine J; Regan, Sarah; Liu, Guo; Alemara, Sarah; Heng, Henry H

2018-01-01

In the past 15 years, impressive progress has been made to understand the molecular mechanism behind aneuploidy, largely due to the effort of using various -omics approaches to study model systems (e.g. yeast and mouse models) and patient samples, as well as the new realization that chromosome alteration-mediated genome instability plays the key role in cancer. As the molecular characterization of the causes and effects of aneuploidy progresses, the search for the general mechanism of how aneuploidy contributes to cancer becomes increasingly challenging: since aneuploidy can be linked to diverse molecular pathways (in regards to both cause and effect), the chances of it being cancerous is highly context-dependent, making it more difficult to study than individual molecular mechanisms. When so many genomic and environmental factors can be linked to aneuploidy, and most of them not commonly shared among patients, the practical value of characterizing additional genetic/epigenetic factors contributing to aneuploidy decreases. Based on the fact that cancer typically represents a complex adaptive system, where there is no linear relationship between lower-level agents (such as each individual gene mutation) and emergent properties (such as cancer phenotypes), we call for a new strategy based on the evolutionary mechanism of aneuploidy in cancer, rather than continuous analysis of various individual molecular mechanisms. To illustrate our viewpoint, we have briefly reviewed both the progress and challenges in this field, suggesting the incorporation of an evolutionary-based mechanism to unify diverse molecular mechanisms. To further clarify this rationale, we will discuss some key concepts of the genome theory of cancer evolution, including system inheritance, fuzzy inheritance, and cancer as a newly emergent cellular system. Illustrating how aneuploidy impacts system inheritance, fuzzy inheritance and the emergence of new systems is of great importance. Such synthesis

Effect of heterogeneity and assumed mode of inheritance on lod scores.

1992-02-01

Heterogeneity is a major factor in many common, complex diseases and can confound linkage analysis. Using computer-simulated heterogeneous data we tested what effect unlinked families have on a linkage analysis when heterogeneity is not taken into account. We created 60 data sets of 40 nuclear families each with different proportions of linked and unlinked families and with different modes of inheritance. The ascertainment probability was 0.05, the disease had a penetrance of 0.6, and the recombination fraction for the linked families was zero. For the analysis we used a variety of assumed modes of inheritance and penetrances. Under these conditions we looked at the effect of the unlinked families on the lod score, the evaluation of the mode of inheritance, and the estimate of penetrance and of the recombination fraction in the linked families. 1. When the analysis was done under the correct mode of inheritance for the linked families, we found that the mode of inheritance of the unlinked families had minimal influence on the highest maximum lod score (MMLS) (i.e., we maximized the maximum lod score with respect to penetrance). Adding sporadic families decreased the MMLS less than adding recessive or dominant unlinked families. 2. The mixtures of dominant linked families with unlinked families always led to a higher MMLS when analyzed under the correct (dominant) mode of inheritance than when analyzed under the incorrect mode of inheritance. In the mixtures with recessive linked families, assuming the correct mode of inheritance generally led to a higher MMLS, but we observed broad variation.(ABSTRACT TRUNCATED AT 250 WORDS)

Inheritance is Specialisation

How can we get a simpler but much more general subclass construct? This position paper takes a "specialisationist" approach to inheritance. Old SIMULA virtues are restored to prominence, but boiled with new unificational ingredients to obtain a substrate of specialisation. Ever since the advent...... of Smalltalk there has been a strong tension in the object-oriented community between two opposing views of the role of inheritance: as an incremental modification mechanism or as a vehicle for conceptual modelling. Madsen [5] and many others characterise the two approaches as the “American ” and “Scandinavian......” schools, respectively. Nowadays, such a geographical terminology hardly remains valid (if ever it was), but the tension remains: should we strive for maximal flexibility of inheritance, to improve the possibilities for later unanticipated reuse, or should we attend above all to the conceptual integrity...

Full Text Available Aim: The present research work was carried out to study the patho-epidemiological aspects of Genotype-XIII Newcastle disease virus (NDV infection in commercial layer in and around Anand, Gujarat. As the outbreaks have reported in vaccinated flocks, it was felt necessary to study the disease with respect to its changing pathogenicity and relevant aspects. Materials and Methods: The study comprised of patho-epidemiology of Newcastle disease (ND by information collected from different layer farms suffering from the disease in relation to incidence pattern and mortality, duration of mortality, susceptible age, and loss due to production performance. Clinical signs were recorded based on observations. During postmortem, gross lesions were also recorded. For histopathological examination visceral organs according to lesions were collected in 10% formalin and processed slide stained by hematoxylin and eosin for microscopic examination. Cultivation of virus was done in embryonated specific pathogen-free (SPF eggs of 9-11 days and isolation of virus was done for haemagglutination (HA and haemagglutination inhibition (HI test and to identify pathotype of virus by intracerebral pathogenicity index (ICPI test to determine the virulence of virus. The Genotype-XIII NDV was confirmed by F gene sequence and whole genome sequence. Results: During the study mortality due to ND was recorded in 13 layer flocks in spite of routine vaccination, which usually contain Genotype-II strain of virus. The mortality was observed as high as above 50% with an average of 21.21%. The susceptible age for disease was found to be 6-14 weeks. The duration of mortality observed was 23 days. The disease resulted in a significant reduction in body weight, feed intake and drop in egg production. Majority of the outbreaks appeared during extremely hot months of April to June. Greenish diarrhoea was frequently seen in birds that survived early in infection. Mortality continued for 2

The evolutionary implications of epigenetic inheritance.

Science.gov (United States)

Jablonka, Eva

2017-10-06

The Modern Evolutionary Synthesis (MS) forged in the mid-twentieth century was built on a notion of heredity that excluded soft inheritance, the inheritance of the effects of developmental modifications. However, the discovery of molecular mechanisms that generate random and developmentally induced epigenetic variations is leading to a broadening of the notion of biological heredity that has consequences for ideas about evolution. After presenting some old challenges to the MS that were raised, among others, by Karl Popper, I discuss recent research on epigenetic inheritance, which provides experimental and theoretical support for these challenges. There is now good evidence that epigenetic inheritance is ubiquitous and is involved in adaptive evolution and macroevolution. I argue that the many evolutionary consequences of epigenetic inheritance open up new research areas and require the extension of the evolutionary synthesis beyond the current neo-Darwinian model.

Since the completion of the Human Genome Project, much has been uncovered about inheritance of various illnesses and disorders. There are two main types of inheritance: Mendelian and non-Mendelian. Mendelian inheritance includes autosomal dominant, autosomal recessive, X-linked, and Y-linked inheritance. Non-Mendelian inheritance includes mitochondrial and multifactorial inheritance. Nurses must understand the types of inheritance in order to identify red flags that may indicate the possibility of a hereditary disorder in a patient or family.

However, aside from generation of adenosine triphosphate, mitochondria have also been found to impact a diversity of cellular functions and organ system health in humans and other eukaryotes. Thus, inheriting and maintaining functional mitochondria are essential for cell health. Due to the relative ease of conducting genetic and molecular biological experiments using fungi, they (especially the budding yeast Saccharomyces cerevisiae have been used as model organisms for investigating the patterns of inheritance and intracellular dynamics of mitochondria and mitochondrial DNA. Indeed, the diversity of mitochondrial inheritance patterns in fungi has contributed to our broad understanding of the genetic, cellular, and molecular controls of mitochondrial inheritance and their evolutionary implications. In this review, we briefly summarize the patterns of mitochondrial inheritance in fungi, describe the genes and processes involved in controlling uniparental mitochondrial DNA inheritance in sexual crosses in basidiomycete yeasts, and provide an overview of the molecular and cellular processes governing mitochondrial inheritance during asexual budding in S. cerevisiae. Together, these studies reveal that complex regulatory networks and molecular processes are involved in ensuring the transmission of healthy mitochondria to the progeny.

To study the inheritance of the sensitivity to UV, X-rays, methylmethanesulphonate (MMS), nitrosoguanidine (NG) and nitrous acid (NA) in five uvs mutants of Aspergillus nidulans, having multiple sensitivity to these factors, the sensitivity of recombinants obtained from crossing uvs mutants with uvs+ strain, resistant to all the factors analysed, and uvs leads to uvs+ revertants is investigated. Four uvs mutants (15, 17, 19 and 26) are found to have a nomogenic control of sensitivity to different mutagens. In one mutant (uvs11) the sensitivity to five factors is controlled by two non-linked mutations, one of them determining the sensitivity to UV, NG, NA, and the other--to X-rays and MMC. Phenotypic manifestations of uvs mutations is modified by cell genotype, both chromosomal and cytoplasmic factors being responsible for the modification. Phenotypic modification of uvs mutation results in the change to some (but not to all) mutagenic factors. It suggests, that not the product of uvs gene, but some other components of the reparation complex are modified. Otherwise, reparation of different DNA damages can be carried out by a single enzyme acting in different reparation complexes.

Biparental chloroplast inheritance leads to rescue from cytonuclear incompatibility.

Science.gov (United States)

Barnard-Kubow, Karen B; McCoy, Morgan A; Galloway, Laura F

2017-02-01

Although organelle inheritance is predominantly maternal across animals and plants, biparental chloroplast inheritance has arisen multiple times in the angiosperms. Biparental inheritance has the potential to impact the evolutionary dynamics of cytonuclear incompatibility, interactions between nuclear and organelle genomes that are proposed to be among the earliest types of genetic incompatibility to arise in speciation. We examine the interplay between biparental inheritance and cytonuclear incompatibility in Campanulastrum americanum, a plant species exhibiting both traits. We first determine patterns of chloroplast inheritance in genetically similar and divergent crosses, and then associate inheritance with hybrid survival across multiple generations. There is substantial biparental inheritance in C. americanum. The frequency of biparental inheritance is greater in divergent crosses and in the presence of cytonuclear incompatibility. Biparental inheritance helps to mitigate cytonuclear incompatibility, leading to increased fitness of F 1 hybrids and recovery in the F 2 generation. This study demonstrates the potential for biparental chloroplast inheritance to rescue cytonuclear compatibility, reducing cytonuclear incompatibility's contribution to reproductive isolation and potentially slowing speciation. The efficacy of rescue depended upon the strength of incompatibility, with a greater persistence of weak incompatibilities in later generations. These findings suggest that incompatible plastids may lead to selection for biparental inheritance. © 2016 The Authors. New Phytologist © 2016 New Phytologist Trust.

Inherited susceptibility to cancer and other factors influencing occurrence of cancer

International Nuclear Information System (INIS)

Pawlak, A.L.

1994-01-01

The types of defects and polymorphisms leading to hereditary susceptibility to cancer include proneness to increased DNA damage, recessive syndromes of faulty DNA repair and differentiation, as well as dominant mutations of cell cycle and control proliferation. The cancer susceptibility syndromes inherited in a dominant fashion are caused by mutations in tumor suppressor genes. These genes are recessive in relation to wild type alleles. In two syndromes of hereditary mutations in tumor suppressor genes (Rb and WT2), their expression 'in vivo' may be influenced by the sex of the transmitting parent, what points to modulation by imprinting. Genetic heterogeneity of the population in susceptibility to genotoxic agents is related to the individual variation in acceptable levels of exposure to agents and factors, such as products of incomplete combustion (PIC), UV ('xeroderma pigmentosum') and ionizing radiation ('ataxia telangiectasia'). DNA damage and adducts are considered to be indicative of genotoxic exposure and its effect as well as modulation of carcinogenic damage by genetic polymorphisms. Gene and protein polymorphisms are considered as markers of increased individual risk. Since environmental factors are considered to be able to control, the individual susceptibility to enhanced DNA damage and environmentally induced cancers could be counteracted by decreasing the levels of contamination or exposure. This explains the wide interest in markers of this individual sensitivity. Most of the postulated markers of sensitivity to PIV do not, however, prove to be generally applicable in that sense. Their prognostic value is limited either by low amplitude of the effect, or by their character specific either to the population or to the cancer type. The polymorphisms most relevant to cancers induced by PIC exposures may be those of inductibility of benzopyrene hydroxylase, and some other DNA polymorphisms concerning the CYP1A1 gene.

Hsieh, J-T; Klein, K; Batstone, M

2017-09-01

Dental extractions challenge the body's haemostatic mechanism. Postoperative bleeding from dental extraction can be prolonged, or even life threatening in patients with inherited bleeding disorders. Pre- and postoperative clotting factor replacements or systemic desmopressin (ddAVP) have been advocated at our institution to prevent bleeding complications in these patients. This study aimed to assess the postoperative bleeding rate in patients with inherited bleeding disorders that underwent dental extractions at our institution between 2003 and 2012. Patients with inherited bleeding disorders such as haemophilia A, haemophilia B, and von Willebrand's disease were included. Retrospective chart review was conducted. The result showed 53 extraction events occurred in 45 patients over the 10-year period. Ten out of 53 extraction events (18.9%) had postoperative bleeding requiring further factor replacement or ddAVP. Postoperative bleeding in one patient with mild haemophilia A was complicated by the development of inhibitors. Type and severity of bleeding disorder, bone removal, and use of a local haemostatic agent did not have any significant effect on postoperative bleeding. Despite the use of perioperative factors and desmopressin, the postoperative bleeding rates remain high for patients with inherited bleeding disorders. More studies are required to assess the safety and effectiveness of using local haemostatic control to achieve haemostasis following extractions. Crown Copyright © 2017. Published by Elsevier Ltd.

Individual variation in social aggression and the probability of inheritance: theory and a field test.

Science.gov (United States)

Cant, Michael A; Llop, Justine B; Field, Jeremy

2006-06-01

Recent theory suggests that much of the wide variation in individual behavior that exists within cooperative animal societies can be explained by variation in the future direct component of fitness, or the probability of inheritance. Here we develop two models to explore the effect of variation in future fitness on social aggression. The models predict that rates of aggression will be highest toward the front of the queue to inherit and will be higher in larger, more productive groups. A third prediction is that, in seasonal animals, aggression will increase as the time available to inherit the breeding position runs out. We tested these predictions using a model social species, the paper wasp Polistes dominulus. We found that rates of both aggressive "displays" (aimed at individuals of lower rank) and aggressive "tests" (aimed at individuals of higher rank) decreased down the hierarchy, as predicted by our models. The only other significant factor affecting aggression rates was date, with more aggression observed later in the season, also as predicted. Variation in future fitness due to inheritance rank is the hidden factor accounting for much of the variation in aggressiveness among apparently equivalent individuals in this species.

Non-traditional inheritance

International Nuclear Information System (INIS)

Hall, J.G.

1992-01-01

In the last few years, several non-traditional forms of inheritance have been recognized. These include mosaicism, cytoplasmic inheritance, uniparental disomy, imprinting, amplification/anticipation, and somatic recombination. Genomic imprinting (GI) is the dependence of the phenotype on the sex of the transmitting parent. GI in humans seems to involve growth, behaviour, and survival in utero. The detailed mechanism of genomic imprinting is not known, but it seems that some process is involved in turning a gene off; this probably involves two genes, one of which produces a product that turns a gene off, and the gene that is itself turned off. The process of imprinting (turning off) may be associated with methylation. Erasure of imprinting can occur, and seems to be associated with meiosis. 10 refs

Uniparental Inheritance Promotes Adaptive Evolution in Cytoplasmic Genomes.

Science.gov (United States)

Christie, Joshua R; Beekman, Madeleine

2017-03-01

Eukaryotes carry numerous asexual cytoplasmic genomes (mitochondria and plastids). Lacking recombination, asexual genomes should theoretically suffer from impaired adaptive evolution. Yet, empirical evidence indicates that cytoplasmic genomes experience higher levels of adaptive evolution than predicted by theory. In this study, we use a computational model to show that the unique biology of cytoplasmic genomes-specifically their organization into host cells and their uniparental (maternal) inheritance-enable them to undergo effective adaptive evolution. Uniparental inheritance of cytoplasmic genomes decreases competition between different beneficial substitutions (clonal interference), promoting the accumulation of beneficial substitutions. Uniparental inheritance also facilitates selection against deleterious cytoplasmic substitutions, slowing Muller's ratchet. In addition, uniparental inheritance generally reduces genetic hitchhiking of deleterious substitutions during selective sweeps. Overall, uniparental inheritance promotes adaptive evolution by increasing the level of beneficial substitutions relative to deleterious substitutions. When we assume that cytoplasmic genome inheritance is biparental, decreasing the number of genomes transmitted during gametogenesis (bottleneck) aids adaptive evolution. Nevertheless, adaptive evolution is always more efficient when inheritance is uniparental. Our findings explain empirical observations that cytoplasmic genomes-despite their asexual mode of reproduction-can readily undergo adaptive evolution. © The Author 2016.

Testamental inheritance: Just a legal osmosis?

Full Text Available Bequeath, a dispose of personal property by the last will is an example of intervention of legislation within the complex of customary law. This influence is not unusual but certainly is less frequent than the influence of customary into civil law, especially so in their interaction within inheritance. This paper therefore tries to explain this example of legal osmosis in practice. In addition, the practice in testament inheritance shows also an influence of customary law into legislation. Hence, the paper will also try to discuss a relationship between customary and civil laws and succeeding problems in inheritance at the levels of individual and that of the society.

We show that for non-conformally flat null fluid spacetimes, the maximum dimension of the inheriting algebra is seven and for conformally flat null fluid spacetimes the maximum dimension is eight. In addition, it is shown that there are two distinct classes of non-conformally flat generalized plane wave spacetimes which possess the maximum dimension, and one class in the conformally flat case

[Mitochondria inheritance in yeast saccharomyces cerevisiae].

2011-01-01

The review is devoted to the main mechanisms of mitochondria inheritance in yeast Saccharonmyces cerevisiae. The genetic mechanisms of functionally active mitochondria inheritance in eukaryotic cells is one of the most relevant in modem researches. A great number of genetic diseases are associated with mitochondria dysfunction. Plasticity of eukaryotic cell metabolism according to the environmental changes is ensured by adequate mitochondria functioning by means of ATP synthesis coordination, reactive oxygen species accumulation, apoptosis regulation and is an important factor of cell adaptation to stress. Mitochondria participation in important for cell vitality processes masters the presence of accurate mechanisms of mitochondria functions regulation according to environment fluctuations. The mechanisms of mitochondria division and distribution are highly conserved. Baker yeast S. cerevisiae is an ideal model object for mitochondria researches due to energetic metabolism lability, ability to switch over respiration to fermentation, and petite-positive phenotype. Correction of metabolism according to the environmental changes is necessary for cell vitality. The influence of respiratory, carbon, amino acid and phosphate metabolism on mitochondria functions was shown. As far as the mechanisms that stabilize functions of mitochondria and mtDNA are highly conserve, we can project yeast regularities on higher eukaryotes systems. This makes it possible to approximate understanding the etiology and pathogenesis of a great number of human diseases.

Mitochondrial DNA inheritance in the human fungal pathogen Cryptococcus gattii.

Wang, Zixuan; Wilson, Amanda; Xu, Jianping

2015-02-01

The inheritance of mitochondrial DNA (mtDNA) is predominantly uniparental in most sexual eukaryotes. In this study, we examined the mitochondrial inheritance pattern of Cryptococcus gattii, a basidiomycetous yeast responsible for the recent and ongoing outbreak of cryptococcal infections in the US Pacific Northwest and British Columbia (especially Vancouver Island) in Canada. Using molecular markers, we analyzed the inheritance of mtDNA in 14 crosses between strains within and between divergent lineages in C. gattii. Consistent with results from recent studies, our analyses identified significant variations in mtDNA inheritance patterns among strains and crosses, ranging from strictly uniparental to biparental. For two of the crosses that showed uniparental mitochondrial inheritance in standard laboratory conditions, we further investigated the effects of the following environmental variables on mtDNA inheritance: UV exposure, temperature, and treatments with the methylation inhibitor 5-aza-2'-deoxycytidine and with the ubiquitination inhibitor ammonium chloride. Interestingly, one of these crosses showed no response to these environmental variables while the other exhibited diverse patterns ranging from complete uniparental inheritance of the MATa parent mtDNA, to biparental inheritance, and to a significant bias toward inheritance of the MATα parental mtDNA. Our results indicate that mtDNA inheritance in C. gattii differs from that in its closely related species Cryptococcus neoformans. Copyright © 2015 Elsevier Inc. All rights reserved.

Does Customary Law Discriminate Balinese Women’s Inheritance Rights?

Directory of Open Access Journals (Sweden)

Hanna Christine Ndun

2018-05-01

Full Text Available There is a stereotype with regard to the rights of the Balinese women on inheriting under the Balinese tradi-tional customary law. It is generally assumed that the law discriminates Balinese women as well as against the human rights principle of equality. This article analyzes the contemporary problems of such issue and would demonstrate the actual principles, rules and practices, including the essential concept of the rights under the Balinese traditional customary law of inheritance. This issue has been explored under a normative legal approach where the resources are primarily taken from the relevant national legal instruments and court decisions, instead of textbooks and journals. An interview has also been commenced for clarifying some aspects of the issue. This article concludes that there has been a generally misleading on viewing the Balinese customary law as discriminating women on an inheritance issue, as in fact, the law also provides rules for supporting women’s rights for inheriting. The law in a certain way has properly preserved the right of women for inheriting in which women under the law have also enjoyed rights for inheriting, especially the daughter and widow. In contrast, the Balinese men that are generally perceived as the ultimate gender enjoying privileges rights to inherit, in the practice of inheritance in the traditional community are also subject to some discrimination. The law has provided a set of rule of inheritance both for men and women where they are subject to certain equal rule and condition. The law also clarifies that both genders are enjoying equal rights on inheritance in a certain portion and situation binding under the principle of balancing between rights and obligation for each side.

Inherited cardiomyopathies and sports participation.

Zorzi, A; Pelliccia, A; Corrado, D

2018-03-01

Competitive sports activity is associated with an increased risk of sudden cardiovascular death in adolescents and young adults with inherited cardiomyopathies. Many young subjects aspire to continue competitive sport after a diagnosis of cardiomyopathy and the clinician is frequently confronted with the problem of eligibility and the request of designing specific exercise programs. Since inherited cardiomyopathies are the leading cause of sudden cardiovascular death during sports performance, a conservative approach implying disqualification of affected athletes from most competitive athletic disciplines is recommended by all the available international guidelines. On the other hand, we know that the health benefits of practicing recreational sports activity can overcome the potential arrhythmic risk in these patients, provided that the type and level of exercise are tailored on the basis of the specific risk profile of the underlying cardiomyopathy. This article will review the available evidence on the sports-related risk of sudden cardiac death and the recommendations regarding eligibility of individuals affected by inherited cardiomyopathies for sports activities.

Why does biparental plastid inheritance revive in angiosperms?

Science.gov (United States)

Zhang, Quan; Sodmergen

2010-03-01

It is widely believed that plastid and mitochondrial genomes are inherited through the maternal parent. In plants, however, paternal transmission of these genomes is frequently observed, especially for the plastid genome. A male gametic trait, called potential biparental plastid inheritance (PBPI), occurs in up to 20% of angiosperm genera, implying a strong tendency for plastid transmission from the male lineage. Why do plants receive organelles from the male parents? Are there clues in plastids that will help to elucidate the evolution of plants? Reconstruction of the ancestral state of plastid inheritance patterns in a phylogenetic context provides insights into these questions. In particular, a recent report demonstrated the unilateral occurrence of PBPI in angiosperms. This result implies that nuclear cytoplasmic conflicts, a basic driving force for altering the mode of organelle inheritance, might have arisen specifically in angiosperms. Based on existing evidence, it is likely that biparental inheritance may have occurred to rescue angiosperm species with defective plastids.

Despite current efforts to combat HIV/AIDS through behavioural change, ingrained socio-cultural practices such as widow inheritance in south-western Uganda has not changed. Low education, unemployment, dowry, widows' socioeconomic demands and the inheritor's greed for the deceased's wealth, influence widow inheritance. Voluntary counselling and testing is needed for the widows and their inheritors; formal dowry should be removed from marriage and widow inheritance stripped of its sexual component.

Does the mode of plastid inheritance influence plastid genome architecture?

Directory of Open Access Journals (Sweden)

Kate Crosby

Full Text Available Plastid genomes show an impressive array of sizes and compactnesses, but the forces responsible for this variation are unknown. It has been argued that species with small effective genetic population sizes are less efficient at purging excess DNA from their genomes than those with large effective population sizes. If true, one may expect the primary mode of plastid inheritance to influence plastid DNA (ptDNA architecture. All else being equal, biparentally inherited ptDNAs should have a two-fold greater effective population size than those that are uniparentally inherited, and thus should also be more compact. Here, we explore the relationship between plastid inheritance pattern and ptDNA architecture, and consider the role of phylogeny in shaping our observations. Contrary to our expectations, we found no significant difference in plastid genome size or compactness between ptDNAs that are biparentally inherited relative to those that are uniparentally inherited. However, we also found that there was significant phylogenetic signal for the trait of mode of plastid inheritance. We also found that paternally inherited ptDNAs are significantly smaller (n = 19, p = 0.000001 than those that are maternally, uniparentally (when isogamous, or biparentally inherited. Potential explanations for this observation are discussed.

Law & psychiatry: Murder, inheritance, and mental illness.

Should a murderer be allowed to inherit the victim's estate? The question dates from biblical times, but most jurisdictions today have statutes in place that bar inheritance by convicted murderers. However, a special problem arises when the killer has a severe mental illness and has been found not guilty by reason of insanity. Should such people, who have not been convicted of a crime, be permitted to collect their inheritance? Jurisdictions vary in their responses, with the rules reflecting a mix of practical and moral considerations influenced by different perspectives about what determines the behavior of persons with mental illness.

Genetic inheritance and epigenetic inheritance are significant determinants of plant evolution, adaptation and plasticity. We studied inheritance of restriction site polymorphisms by the f-AFLP method and epigenetic DNA cytosine methylation inheritance by the f-MSAP technique. The study involved parents and 190 progeny of a Cupressus sempervirens L. full-sib family. Results from AFLP genetic data revealed that 71.8% of the fragments studied are under Mendelian genetic control, whereas faithful Mendelian inheritance for the MSAP fragments was low (4.29%). Further, MSAP fragment analysis showed that total methylation presented a mean of 28.2%, which was higher than the midparent value, while maternal inheritance was higher (5.65%) than paternal (3.01%). Interestingly de novo methylation in the progeny was high (19.65%) compared to parental methylation. Genetic and epigenetic distances for parents and offspring were not correlated (R(2)=0.0005). Furthermore, we studied correlation of total relative methylation and CG methylation with growth (height, diameter). We found CG/CNG methylation (N: A, C, T) to be positively correlated with height and diameter, while total relative methylation and CG methylation were positively correlated with height. Results are discussed in light of further research needed and of their potential application in breeding. Copyright © 2015 Elsevier B.V. All rights reserved.

Intergenerational epigenetic inheritance in reef-building corals

KAUST Repository

Liew, Yi Jin

2018-02-22

The notion that intergenerational or transgenerational inheritance operates solely through genetic means is slowly being eroded: epigenetic mechanisms have been shown to induce heritable changes in gene activity in plants and metazoans. Inheritance of DNA methylation provides a potential pathway for environmentally induced phenotypes to contribute to evolution of species and populations. However, in basal metazoans, it is unknown whether inheritance of CpG methylation patterns occurs across the genome (as in plants) or as rare exceptions (as in mammals). Here, we demonstrate genome-wide intergenerational transmission of CpG methylation patterns from parents to sperm and larvae in a reef-building coral. We also show variation in hypermethylated genes in corals from distinct environments, indicative of responses to variations in temperature and salinity. These findings support a role of DNA methylation in the transgenerational inheritance of traits in corals, which may extend to enhancing their capacity to adapt to climate change.

Full Text Available Data mining and pattern recognition methods reveal interesting findings in genetic studies, especially on how genetic makeup is associated with inherited diseases. Although researchers have proposed various data mining models for biomedical approaches, there remains a challenge in accurately determining the responsible genetic factors for prioritizing the single nucleotide polymorphisms (SNP associated with the disease. In this commentary, we review the state-of-art data mining and pattern recognition models for identifying inherited diseases and deliberate the need of binary classification and scoring based prioritization methods for determining causal variants. While we discuss the pros and cons associated with these methods known, we argue that the gene prioritization methods and the protein interaction (PPI methods in conjunction with the K nearest neighbors’ could be used in accurately categorizing the genetic factors in disease causation

Sharing the cell's bounty - organelle inheritance in yeast.

Eukaryotic cells replicate and partition their organelles between the mother cell and the daughter cell at cytokinesis. Polarized cells, notably the budding yeast Saccharomyces cerevisiae, are well suited for the study of organelle inheritance, as they facilitate an experimental dissection of organelle transport and retention processes. Much progress has been made in defining the molecular players involved in organelle partitioning in yeast. Each organelle uses a distinct set of factors - motor, anchor and adaptor proteins - that ensures its inheritance by future generations of cells. We propose that all organelles, regardless of origin or copy number, are partitioned by the same fundamental mechanism involving division and segregation. Thus, the mother cell keeps, and the daughter cell receives, their fair and equitable share of organelles. This mechanism of partitioning moreover facilitates the segregation of organelle fragments that are not functionally equivalent. In this Commentary, we describe how this principle of organelle population control affects peroxisomes and other organelles, and outline its implications for yeast life span and rejuvenation. © 2015.

Full Text Available The mode of Scheuermann’s disease inheritance and its phenotypic traits in probands and their relatives were studied in 90 pedigrees (90 probands and 385 relatives. The disorder was identified as a genetically related pathology inherited by autosomal dominant type, controlled by a mutant major gene, as a kyphotic deformity without signs of vertebral bodies’ anomaly and torsion. Morphological and biochemical studies showed disturbance in the structure of vertebral growth plate anterior aspects at the level of deformity, defects in proliferation and differentiation of chondrocytes, and change in proteoglycan spectrum in cells and matrix. Twelve candidate genes were studied in chondrocytes isolated from vertebral growth plates of patients with Scheuermann’s disease. The study results included disorder in the IHH gene expression and preservation of the expression of PAX1, two aggrecan isoforms, link protein, types I and II collagen, lumican, versican, growth hormone and growth factor receptor genes, and proliferation gene. Preservation of the SOX9 gene (transcription gene probably indicates posttranscriptional genetic disorders. The study is under way.

Inheritance and wealth inequality: Evidence from population registers

Elinder, Mikael; Erixson, Oscar; Waldenström, Daniel

2016-01-01

We use new population-wide register data on inheritances and wealth in Sweden to estimate the causal impact of inheritances on wealth inequality. We find that inheritances reduce relative wealth inequality (e.g., the Gini coefficient falls by 5–10 percent) but that absolute dispersion increases. Examining different parts of the wealth distribution, we find that the top decile's wealth share decreases substantially, whereas the wealth share of the bottom half increases from a negative to a pos...

Organelle Genome Inheritance in Deparia Ferns (Athyriaceae, Aspleniineae, Polypodiales

2018-04-01

Full Text Available Organelle genomes of land plants are predominately inherited maternally but in some cases can also be transmitted paternally or biparentally. Compared to seed plants (>83% genera of angiosperms and >12% genera of gymnosperms, plastid genome (plastome inheritance has only been investigated in fewer than 2% of fern genera, and mitochondrial genome (mitogenome from only one fern genus. We developed a new and efficient method to examine plastome and mitogenome inheritance in a fern species—Deparia lancea (Athyriaceae, Aspleniineae, Polypodiales, and found that plastid and mitochondrial DNAs were transmitted from only the maternal parentage to a next generation. To further examine whether both organelle genomes have the same manner of inheritance in other Deparia ferns, we sequenced both plastid and mitochondrial DNA regions of inter-species hybrids, and performed phylogenetic analyses to identify the origins of organellar DNA. Evidence from our experiments and phylogenetic analyses support that both organelle genomes in Deparia are uniparentally and maternally inherited. Most importantly, our study provides the first report of mitogenome inheritance in eupolypod ferns, and the second one among all ferns.

In an earlier paper (see Nuovo Cimento B, 19 (2004) 1187) it was conjectured that none of the well-known spherically symmetric static space-time solutions of the Einstein equations admit non-trivial Ricci inheritance symmetry. In this paper we discuss Ricci inheritance (R I) symmetry in three well-known non static spherically symmetric space-time metrics and show that our conjecture is also valid in non-static space-time metrics.

2009-04-19

Thromboembolic events are relatively uncommon in childhood. It involves mainly children under one year of age and adolescents, with an incidence is 5.1/10000 live births. Authors present a course of disease of seven cases with neonatal thromboembolic events (2.5/admissions), diagnosed and treated at the Neonatal Division of Department of Pediatrics. In three of seven cases thrombosis proved to be of intrauterine origin. In each of the latter cases, inherited thrombophilia of the mothers was detected. Additional risk factors including infection could be revealed only in one case. Using in vivo and post mortem DNA analysis, mother-like-thrombophilia could not be confirmed in any of the newborns. Based on their experiences, authors suppose that undetected predisposing factors added to maternal thrombophilia can be considered as etiological factor. Authors suggest the intensive follow-up of pregnant women with thrombophilia and also their fetuses.

Epigenetic Inheritance Across the Landscape

Directory of Open Access Journals (Sweden)

Amy Vaughn Whipple

2016-10-01

Full Text Available The study of epigenomic variation at the landscape-level in plants may add important insight to studies of adaptive variation. A major goal of landscape genomic studies is to identify genomic regions contributing to adaptive variation across the landscape. Heritable variation in epigenetic marks, resulting in transgenerational plasticity, can influence fitness-related traits. Epigenetic marks are influenced by the genome, the environment, and their interaction, and can be inherited independently of the genome. Thus, epigenomic variation likely influences the heritability of many adaptive traits, but the extent of this influence remains largely unknown. Here we summarize the relevance of epigenetic inheritance to ecological and evolutionary processes, and review the literature on landscape-level patterns of epigenetic variation. Landscape-level patterns of epigenomic variation in plants generally show greater levels of isolation by distance and isolation by environment then is found for the genome, but the causes of these patterns are not yet clear. Linkage between the environment and epigenomic variation has been clearly shown within a single generation, but demonstrating transgenerational inheritance requires more complex breeding and/or experimental designs. Transgenerational epigenetic variation may alter the interpretation of landscape genomic studies that rely upon phenotypic analyses, but should have less influence on landscape genomic approaches that rely upon outlier analyses or genome-environment associations. We suggest that multi-generation common garden experiments conducted across multiple environments will allow researchers to understand which parts of the epigenome are inherited, as well as to parse out the relative contribution of heritable epigenetic variation to the phenotype.

Myeloproliferative disorders and secondary polycythemia cover most of the polycythemia cases encountered in daily practice. Inherited polycythemias are rare entities that have to be suspected when the classical causes of acquired polycythemia have been ruled out. Recent advances were made in the understanding of these pathologies, which are still little known to the physicians. This review reports the state of knowledge and proposes an algorithm to follow when confronted to a possible case of inherited polycythemia.

Selective sweeps of mitochondrial DNA can drive the evolution of uniparental inheritance.

Science.gov (United States)

Christie, Joshua R; Beekman, Madeleine

2017-08-01

Although the uniparental (or maternal) inheritance of mitochondrial DNA (mtDNA) is widespread, the reasons for its evolution remain unclear. Two main hypotheses have been proposed: selection against individuals containing different mtDNAs (heteroplasmy) and selection against "selfish" mtDNA mutations. Recently, uniparental inheritance was shown to promote adaptive evolution in mtDNA, potentially providing a third hypothesis for its evolution. Here, we explore this hypothesis theoretically and ask if the accumulation of beneficial mutations provides a sufficient fitness advantage for uniparental inheritance to invade a population in which mtDNA is inherited biparentally. In a deterministic model, uniparental inheritance increases in frequency but cannot replace biparental inheritance if only a single beneficial mtDNA mutation sweeps through the population. When we allow successive selective sweeps of mtDNA, however, uniparental inheritance can replace biparental inheritance. Using a stochastic model, we show that a combination of selection and drift facilitates the fixation of uniparental inheritance (compared to a neutral trait) when there is only a single selective mtDNA sweep. When we consider multiple mtDNA sweeps in a stochastic model, uniparental inheritance becomes even more likely to replace biparental inheritance. Our findings thus suggest that selective sweeps of beneficial mtDNA haplotypes can drive the evolution of uniparental inheritance. © 2017 The Author(s).

Social inheritance can explain the structure of animal social networks

Science.gov (United States)

Ilany, Amiyaal; Akçay, Erol

2016-01-01

The social network structure of animal populations has major implications for survival, reproductive success, sexual selection and pathogen transmission of individuals. But as of yet, no general theory of social network structure exists that can explain the diversity of social networks observed in nature, and serve as a null model for detecting species and population-specific factors. Here we propose a simple and generally applicable model of social network structure. We consider the emergence of network structure as a result of social inheritance, in which newborns are likely to bond with maternal contacts, and via forming bonds randomly. We compare model output with data from several species, showing that it can generate networks with properties such as those observed in real social systems. Our model demonstrates that important observed properties of social networks, including heritability of network position or assortative associations, can be understood as consequences of social inheritance.

Strains are phenotypic variants, encoded by nucleic acid sequences in chromosomal inheritance and by protein “conformations” in prion inheritance and transmission. But how is a protein “conformation” stable enough to endure transmission between cells or organisms? Here new polymorphic crystal structures of segments of prion and other amyloid proteins offer structural mechanisms for prion strains. In packing polymorphism, prion strains are encoded by alternative packings (polymorphs) of β-sheets formed by the same segment of a protein; in a second mechanism, segmental polymorphism, prion strains are encoded by distinct β-sheets built from different segments of a protein. Both forms of polymorphism can produce enduring “conformations,” capable of encoding strains. These molecular mechanisms for transfer of information into prion strains share features with the familiar mechanism for transfer of information by nucleic acid inheritance, including sequence specificity and recognition by non-covalent bonds.

Factor VII (FVII) is a plasma glycoprotein that plays a key role in the initiation of blood coagulation cascade. Inherited FVII deficiency is a rare autosomal recessive disorder with a wide heterogeneous clinical pattern. The severe form may be associated with intracranial haemorrhages occurring closely to birth with a high mortality rate. In the present article, we report two novel cases of neonatal intracerebral bleeding associated with FVII activity levels below 1% of normal. FVII genotyping investigations revealed particular genotypes including the deleterious Cys135Arg mutation and a novel Ser52Stop nonsense mutation at the homozygous state. Both mutations, through different mechanisms, are expected to be inconsistent with the production of functional FVII. These putative mechanisms are discussed through a review of the literature on phenotypic and genotypic characteristics of cerebral haemorrhages in severe inherited FVII deficiency.

Effect of Factor XIII-A G185T Polymorphism on Visual Prognosis after Photodynamic Therapy for Neovascular Macular Degeneration

Full Text Available Macular degenerations represent leading causes of central blindness or low vision in developed countries. Most of these severe visual disabilities are due to age-related macular degeneration (AMD and pathologic myopia (PM, both of which are frequently complicated by subfoveal choroidal neovascularization (CNV. Photodynamic therapy with verteporfin (PDT-V is still employed for CNV treatment in selected cases or in combined regimen. In Caucasian patients, the common polymorphism G185T of factor XIII-A gene (FXIII-A-G185T; rs5985 has been described as predictor of poor angiographic CNV responsiveness to PDT-V. Nevertheless, the prognostic implications of this pharmacogenetic determinant on long-term visual outcome after a PDT-V regimen have not been evaluated. We retrospectively selected Caucasian patients presenting with treatment-naive CNV and receiving standardized PDT-V protocol for two years. The study population included patients affected by subfoveal CNV secondary to AMD or PM. We assessed the correlations between the polymorphic allele T of FXIII-A-G185T and: (1 total number of photodynamic treatments; and (2 change in visual acuity from baseline to the end of the follow-up period. Considering a total study population of 412 patients with neovascular AMD or PM, the carriers of 185 T-allele of FXIII-A (GT or TT genotype received a higher number of photodynamic treatments than patients without it (GG wild-type genotype (p < 0.01; mean number of PDT-V: 5.51 vs. 3.76, respectively. Moreover, patients with 185 T-allele of FXIII-A had a more marked worsening of visual acuity at 24 months than those with the GG-185 wild genotype (p < 0.01; mean difference in logMAR visual acuity: 0.22 vs. 0.08, respectively. The present findings show that the G185T polymorphism of the FXIII-A gene is associated with significant differences in the long-term therapeutic outcomes of patients treated with standardized PDT-V protocol.

At the beginning of the XIII century the archaeologists have found evidence of a singular, transitional, pottery technique limited to a small area around western Liguria (Northwest of Italy). Known as Ligurian Protomajolica (PML), it shows in the same ceramic body and on the same surface white slip and enamel together, addressing questions about the technical reasons of this unusual combination, its origin and evolution. To integrate previous morphological and mineralogical studies, we have analysed by particle induced X-ray emission (also with mapping) and ionoluminescence (IL) the ceramic body, slip and glaze composition of 56 samples, of which 25 PML’s. We have identified some PML’s compositional features which are distinct from those of other coeval or later productions from the same area. A few PML imitations are described. A plausible explanation of the origin of the PML’s, based both on the archaeometric results and the archaeological and historical knowledge, is presented.

Arrhythmogenic cardiomyopathy (ACM) is an inherited genetic disorder, characterized by the substitution of heart muscle with fibro-fatty tissue and severe ventricular arrhythmias, often leading to heart failure and sudden cardiac death. ACM is considered a monogenic disorder, but the low penetrance of mutations identified in patients suggests the involvement of additional genetic or environmental factors. We used whole exome sequencing to investigate digenic inheritance in two ACM families where previous diagnostic tests have revealed a PKP2 mutation in all affected and some healthy individuals. In family members with PKP2 mutations we determined all genes that harbor variants in affected but not in healthy carriers or vice versa. We computationally prioritized the most likely candidates, focusing on known ACM genes and genes related to PKP2 through protein interactions, functional relationships, or shared biological processes. We identified four candidate genes in family 1, namely DAG1, DAB2IP, CTBP2 and TCF25, and eleven candidate genes in family 2. The most promising gene in the second family is TTN, a gene previously associated with ACM, in which the affected individual harbors two rare deleterious-predicted missense variants, one of which is located in the protein's only serine kinase domain. In this study we report genes that might act as digenic players in ACM pathogenesis, on the basis of co-segregation with PKP2 mutations. Validation in larger cohorts is still required to prove the utility of this model.

Legal Inheritance in the Republic of Kosovo

Full Text Available Legal inheritance is one of the most important institutions of inheritance law which regulates the process of legal transition of property of the decedent to one or several heirs. The establish-ment of the legal framework has brought about new reforms to the Inheritance Law. This has enabled the enrichment and functio-ning of the law. A particularly important step was taken towards regulation of legal procedures regarding to how courts, other or-gans and other persons should act regarding inheritance issues. Concretization of the legal authorizations of bodies authorized to enforce the procedure of processing hereditary property has estab-lished the legal basis for realization of the iso jure principle, accor-ding to which, at the moment of death of the person, the heirs gain the right of inheritance and the hereditary property is never left without a titleholder. This is a great advantage that we have noted in undertaking this analysis of the norms in this work, because leaving hereditary property for a longer period of time without a titleholder would render the property vulnerable to des-truction, theft and extermination. The goal of this paper is to avoid focusing only on finding the positive sides of the normative regulation of the legal inheritance process, but also in finding practical deficiencies that are weighing down at the moment on this important process in Kosovo, and in proposing measures for overcoming them. The dark side of the legal inheritance process is linked to the inefficiency of courts and the still fragile legal system in Kosovo. By implementing empirical methods, we have come to the con-clusion that the low number of judges in proportion with the huge number of cases has become a key liability for practical implemen-tation of the principle of initiating the legal procedure ex officio. The failure in enforcing this principle and initiating the procedu-res for processing of hereditary property by courts, even though they

Symmetry inheritance of scalar fields

International Nuclear Information System (INIS)

Ivica Smolić

2015-01-01

Matter fields do not necessarily have to share the symmetries with the spacetime they live in. When this happens, we speak of the symmetry inheritance of fields. In this paper we classify the obstructions of symmetry inheritance by the scalar fields, both real and complex, and look more closely at the special cases of stationary and axially symmetric spacetimes. Since the symmetry noninheritance is present in the scalar fields of boson stars and may enable the existence of the black hole scalar hair, our results narrow the possible classes of such solutions. Finally, we define and analyse the symmetry noninheritance contributions to the Komar mass and angular momentum of the black hole scalar hair. (paper)

2006-10-01

The prevalence of bleeding disorders, notably von Willebrand disease (vWD), among adult women with objectively documented menorrhagia is consistently reported to be 10% to 20% and is even higher in adolescents presenting with menorrhagia. This consensus document has been developed by a multidisciplinary committee consisting of an anesthesiologist, 2 hematologists, and an obstetrician/gynaecologist and has been endorsed by their relevant specialty bodies. It has been prepared with the express purpose of providing guidelines for both women with inherited bleeding disorders and for their caregivers regarding the gynaecological and obstetric management of these women, including appropriate anesthesia support where indicated. Diagnostic tools and specific medical and, where appropriate, surgical alternatives to management are reviewed and evidence-based recommendations presented. A MEDLINE search of the English literature between January 1975 and November 2003 was performed using the following key words: menorrhagia, uterine bleeding, pregnancy, von Willebrand, congenital bleeding disorder, desmopressin/DDAVP, tranexamic acid, oral contraceptives, medroxyprogesterone, therapy, hysterectomy, anesthesia, epidural, spinal. Recommendations from other society guidelines were reviewed. 1. Inherited bleeding disorders should be considered in the differential diagnosis of all patients presenting with menorrhagia (II-2B). The graphical scoring system presented is a validated tool which offers a simple yet practical method that can be used by patients to quantify their blood loss (II-2B). 2. Because underlying bleeding disorders are frequent in women with menorrhagia, physicians should consider performing a hemoglobin/hematocrit, platelet count, ferritin, PT (INR) and APTT in women with menorrhagia. In women who have a personal history of other bleeding or a family history of bleeding, further investigation should be considered, including a vWD workup (factor VIII, vWF antigen

Arm-Gal4 inheritance influences development and lifespan in Drosophila melanogaster.

Slade, F A; Staveley, B E

2015-10-19

The UAS-Gal4 ectopic expression system is a widely used and highly valued tool that allows specific gene expression in Drosophila melanogaster. Yeast transcription factor Gal4 can be directed using D. melanogaster transcriptional control elements, and is often assumed to have little effect on the organism. By evaluation of the consequences of maternal and paternal inheritance of a Gal4 transgene under the transcriptional regulation of armadillo control elements (arm-Gal4), we demonstrated that Gal4 expression could be detrimental to development and longevity. Male progeny expressing arm-Gal4 in the presence of UAS-lacZ transgene had reduced numbers and size of ommatidia, compared to flies expressing UAS-lacZ transgene under the control of other Gal4 transgenes. Aged at 25°C, the median life span of male flies with maternally inherited elav-Gal4 was 70 days, without a responding transgene or with UAS-lacZ. The median life span of maternally inherited arm-Gal4 male flies without a responding transgene was 48 days, and 40 days with the UAS-lacZ transgene. A partial rescue of this phenotype was observed with the expression of UAS-lacZ under paternal arm-Gal4 control, having an average median lifespan of 60 days. This data suggests that arm-Gal4 has detrimental effects on Drosophila development and lifespan that are directly dependent upon parental inheritance, and that the benign responder and reporter gene UAS-lacZ may influence D. melanogaster development. These findings should be taken into consideration during the design and execution of UAS-Gal4 expression experiments.

Cross Border Inheritances and European Community Law : Juridical double taxation of inheritances and the free movement of capital

OpenAIRE

Wiberg, Caroline

2009-01-01

Double taxation is known as restricting the free flow of capital and accordingly results in a limited access of the internal market. Although, not many Member States have entered into double taxation conventions in order to avoid juridical double taxation of inheritances. The question then arises whether this failure to eliminate juridical double taxation is restricting the free movement of capital. The ECJ‟s case law regarding inheritance taxes are very varying. In its initial case law, the ...

The Decline of the Swedish Inheritance and Gift Tax, 1991–2004

OpenAIRE

Eriksson, Martin; Gunnarsson, Åsa

2017-01-01

During the period 1991–2004, political support for the inheritance and gift taxation in Sweden diminished, which contributed to two major policy shifts. In 1991, a new tax schedule which reduced top rates was introduced. The tax was thereafter completely repealed in 2004. In this paper, we examine how background factors such as competitiveness and political legitimacy influenced these decisions. By studying the preceding decision-making processes, we find that the influence of these factors s...

Inheritance for software reuse: The good, the bad, and the ugly

Sitaraman, Murali; Eichmann, David A.

1992-01-01

Inheritance is a powerful mechanism supported by object-oriented programming languages to facilitate modifications and extensions of reusable software components. This paper presents a taxonomy of the various purposes for which an inheritance mechanism can be used. While some uses of inheritance significantly enhance software reuse, some others are not as useful and in fact, may even be detrimental to reuse. The paper discusses several examples, and argues for a programming language design that is selective in its support for inheritance.

2017-07-01

Alport syndrome (ATS) is a genetically heterogeneous nephropathy with considerable phenotypic variability and different transmission patterns, including monogenic (X-linked/autosomal) and digenic inheritance (DI). Here we present a new series of families with DI and we discuss the consequences for genetic counseling and risk assessment. Out of five families harboring variants in more than one COL4 gene detected by next generation sequencing (NGS), minigene-splicing assay allowed us to identify four as true digenic. Two families showed COL4A3/A4 mutations in cis, mimicking an autosomal dominant inheritance with a more severe phenotype and one showed COL4A3/A4 mutations in trans, mimicking an autosomal recessive inheritance with a less severe phenotype. In a fourth family, a de novo mutation (COL4A5) combined with an inherited mutation (COL4A3) triggered a more severe phenotype. A fifth family, predicted digenic on the basis of silico tools, rather showed monogenic X-linked inheritance due to a hypomorphic mutation, in accordance with a milder phenotype. In conclusion, this study highlights the impact of DI in ATS and explains the associated atypical presentations. More complex inheritance should be therefore considered when reviewing prognosis and recurrence risks. On the other side, these findings emphasize the importance to accompany NGS with splicing assays in order to avoid erroneous identification of at risk members. © 2016 John Wiley & Sons A/S.

To document the clinical characteristics and inheritance pattern of epilepsy in multigeneration Algerian families. Affected members from extended families with familial epilepsy were assessed at the University Hospital of Oran in Algeria. Available medical records, neurological examination, electroencephalography and imaging data were reviewed. The epilepsy type was classified according to the criteria of the International League Against Epilepsy and modes of inheritance were deduced from pedigree analysis. The study population included 40 probands; 23 male (57.5%) and 17 female subjects (42.5%). The mean age of seizure onset was 9.5 ± 6.1 years. According to seizure onset, 16 patients (40%) had focal seizures and 20 (50%) had generalized seizures. Seizure control was achieved for two patients (5%) for 10 years, while 28 (70%) were seizure-free for 3 months. Eleven patients (27.5%) had prior febrile seizures, 12 were diagnosed with psychiatric disorders and four families had syndromic epilepsy. The consanguinity rate among parents of affected was 50% with phenotypic concordance observed in 25 families (62.5%). Pedigree analysis suggested autosomal dominant (AD) inheritance with or without reduced penetrance in 18 families (45%), probable autosomal recessive (AR) inheritance in 14 families (35%), and an X-linked recessive inheritance in one family. This study reveals large Algerian families with multigenerational inheritance of epilepsy. Molecular testing such as exome sequencing would clarify the genetic basis of epilepsy in some of our families. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd.

Studies have shown an association between recurrent pregnancy loss and inherited thrombophilia in Caucasian populations, but there is insufficient knowledge concerning triethnic populations such as the Colombian. The aim of this study was to evaluate whether inherited thrombophilia is associated with recurrent pregnancy loss. Methods. We conducted a case-control study of 93 patients with recurrent pregnancy loss (cases) and 206 healthy multiparous women (controls) in a Colombian subpopulation. Three single nucleotide polymorphisms (SNPs) markers of the inherited thrombophilias factor V Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase C677T were genotyped by PCR-RFLP. Activated protein C resistance and plasma levels of antithrombin, protein C, and protein S were also measured. Results. The frequency of thrombophilia-associated SNPs, activated protein C resistance, and anticoagulant protein deficiencies, was low overall, except for the methylenetetrahydrofolate reductase C677T SNP. The differences between patients and controls had no statistical significance. Conclusion. Our study confirms the low prevalence of inherited thrombophilias in non-Caucasian populations and it is unlikely that the tested thrombophilias play a role in the pathogenesis of recurrent pregnancy loss in this Colombian population.

Hall, Michael J; Forman, Andrea D; Pilarski, Robert; Wiesner, Georgia; Giri, Veda N

2014-09-01

Next-generation sequencing technologies have ushered in the capability to assess multiple genes in parallel for genetic alterations that may contribute to inherited risk for cancers in families. Thus, gene panel testing is now an option in the setting of genetic counseling and testing for cancer risk. This article describes the many gene panel testing options clinically available to assess inherited cancer susceptibility, the potential advantages and challenges associated with various types of panels, clinical scenarios in which gene panels may be particularly useful in cancer risk assessment, and testing and counseling considerations. Given the potential issues for patients and their families, gene panel testing for inherited cancer risk is recommended to be offered in conjunction or consultation with an experienced cancer genetic specialist, such as a certified genetic counselor or geneticist, as an integral part of the testing process.

2002-08-01

The study of inborn errors of metabolism (IEM) in Thailand is in its infancy. The majority are clinically diagnosed since there are only a handful of clinicians and scientists with expertise in inherited metabolic disorders, shortage of well-equipped laboratory facilities and lack of governmental financial support. Genetic metabolic disorders are usually not considered a priority due to prevalence of infectious diseases and congenital infections. From a retrospective study at the Medical Genetics Unit, Department of Pediatrics, Siriraj Hospital; estimated pediatrics patients with suspected IEM were approximately 2-3 per cent of the total pediatric admissions of over 5,000 annually. After more than 10 years of research and accumulated clinical experiences, a genetic metabolic center is being established in collaboration with expert laboratories both in Bangkok (Chulabhorn Research Institute) and abroad (Japan and the United States). Numerous inherited metabolic disorders were identified--carbohydrate, amino acids, organic acids, mitochondrial fatty acid oxidation, peroxisomal, mucopolysaccharidoses etc. This report includes the establishment of genetic metabolic center in Thailand, research and pilot studies in newborn screening in Thailand and a multicenter study from 5 institutions (Children's National Center, King Chulalongkorn Memorial Hospital, Pramongkutklao Hospital, Ramathibodi and Siriraj Hospitals). Inherited metabolic disorders reported are fructose-1,6-bisphosphatase deficiency, phenylketonuria, homocystinuria, nonketotic hyperglycinemia, urea cycle defect (arginino succinate lyase deficiency, argininosuccinate synthetase deficiency), Menkes disease, propionic acidemia and mucopolysaccharidoses (Hurler, Hurler-Scheie).

Endangering of Businesses by the German Inheritance Tax? – An Empirical Analysis

Directory of Open Access Journals (Sweden)

Henriette Houben

2011-04-01

Full Text Available This contribution addresses the substantial tax privilege for businesses introduced by the German Inheritance Tax Act 2009. Advocates of the vast or even entire tax exemption for businesses stress the potential damage of the inheritance tax on businesses, as those often lack liquidity to meet tax liability. This submission tackles this issue empirically based on data of the German Inheritance Tax Statistics and the SOEP. The results indicate that former German inheritance tax law has not endangered transferred businesses. Hence, there is no need for the tremendous tax privilege for businesses in current German inheritance tax law. An alternative flat inheritance tax without tax privileges, which meets revenue neutrality per tax class according to current tax law, provokes in some cases relative high tax loads which might trouble businesses.

Use/disuse paradigms are ubiquitous concepts in characterizing the process of inheritance.

Science.gov (United States)

Veigl, Sophie Juliane

2017-12-02

In recent years, a Lamarckian theme has found its way back into academic discourse on evolution and inheritance. Especially the emerging field of transgenerational small RNAs has provided at least a proof of concept for the inheritance of acquired traits. Yet it remains unclear whether the Lamarckian concept of inheritance will in fact have its rennaisance or whether it will remain the rallying cry for the outlaws, heretics and enfants terribles of molecular biology. As unclear as the future of Lamarckian theory is its content and reference. Since the formulation of the Philosophie Zoologique, Lamarckian thought has been de- and reconfiguring in and out of the scientific literature and become an umbrella-term for all kinds of unconventional modes of inheritance. This essay will argue that heritable small RNAs might in fact provide a case of genuine Lamarckian inheritance. Moreover, it will be claimed that not only the very broad concept of "inheritance of acquired traits" applies, but also that Lamarck's mechanistic insight into a use/disuse relation might help to explain a specific mode of transgenerational inheritance.

2003-01-22

With complete knowledge of the human genome sequence, one of the most interesting tasks remaining is to understand the functions of individual genes and how they communicate. Using the information about genes (locus, allele, mutation rate, fitness, etc.), we attempt to explain population demographic data. This population evolution study could complement and enhance biologists' understanding about genes. We present a general approach to study population genetics in complex situations. In the present approach, multiple allele inheritance, multiple loci inheritance, natural selection and mutations are allowed simultaneously in order to consider a more realistic situation. A simulation program is presented so that readers can readily carry out studies with their own parameters. It is shown that the multiplicity of the loci greatly affects the demographic results of fractional population ratios. Furthermore, the study indicates that some high infant mortality rates due to congenital anomalies can be attributed to multiple loci inheritance. The simulation program can be downloaded from http://won.hongik.ac.kr/~mhchung/index_files/yapop.htm. In order to run this program, one needs Visual Studio.NET platform, which can be downloaded from http://msdn.microsoft.com/netframework/downloads/default.asp.

Certain peculiarities of structural inheritance in phase recrystallization of steel

International Nuclear Information System (INIS)

Mukhamedov, A.A.

1978-01-01

The structural inheritance in phase recrystallization of previously overheated to various temperatures industrially melted 40Kh steel and of Armco-iron has been investigated. The steels have been heated to 100O, 11O0, 1200 and 1260 deg C and cooled in the air, and in some instances, hardened (quenched) in water. The physical broadening of X-ray lines points to a nonmonotonous variation of fine structure parameters as a function of the temperature and the heating time. The inheritance effect of fine structure defects affects the steel properties obtained in a final heat treatment. The structural inheritance effect has an important bearing upon the wear resistance of steel. A purpose-oriented use of the structural inheritance effect can enhance service properties of steel parts

Overexpression of Human-Derived DNMT3A Induced Intergenerational Inheritance of Active DNA Methylation Changes in Rat Sperm

Directory of Open Access Journals (Sweden)

Xiaoguo Zheng

2017-12-01

Full Text Available DNA methylation is the major focus of studies on paternal epigenetic inheritance in mammals, but most previous studies about inheritable DNA methylation changes are passively induced by environmental factors. However, it is unclear whether the active changes mediated by variations in DNA methyltransferase activity are heritable. Here, we established human-derived DNMT3A (hDNMT3A transgenic rats to study the effect of hDNMT3A overexpression on the DNA methylation pattern of rat sperm and to investigate whether this actively altered DNA methylation status is inheritable. Our results revealed that hDNMT3A was overexpressed in the testis of transgenic rats and induced genome-wide alterations in the DNA methylation pattern of rat sperm. Among 5438 reliable loci identified with 64 primer-pair combinations using a methylation-sensitive amplification polymorphism method, 28.01% showed altered amplified band types. Among these amplicons altered loci, 68.42% showed an altered DNA methylation status in the offspring of transgenic rats compared with wild-type rats. Further analysis based on loci which had identical DNA methylation status in all three biological replicates revealed that overexpression of hDNMT3A in paternal testis induced hypermethylation in sperm of both genotype-negative and genotype-positive offspring. Among the differentially methylated loci, 34.26% occurred in both positive and negative offspring of transgenic rats, indicating intergenerational inheritance of active DNA methylation changes in the absence of hDNM3A transmission. Furthermore, 75.07% of the inheritable loci were hyper-methylated while the remaining were hypomethylated. Distribution analysis revealed that the DNA methylation variations mainly occurred in introns and intergenic regions. Functional analysis revealed that genes related to differentially methylated loci were involved in a wide range of functions. Finally, this study demonstrated that active DNA methylation

Data mining and pattern recognition methods reveal interesting findings in genetic studies, especially on how the genetic makeup is associated with inherited diseases. Although researchers have proposed various data mining models for biomedical approaches, there remains a challenge in accurately prioritizing the single nucleotide polymorphisms (SNP) associated with the disease. In this commentary, we review the state-of-art data mining and pattern recognition models for identifying inherited diseases and deliberate the need of binary classification- and scoring-based prioritization methods in determining causal variants. While we discuss the pros and cons associated with these methods known, we argue that the gene prioritization methods and the protein interaction (PPI) methods in conjunction with the K nearest neighbors' could be used in accurately categorizing the genetic factors in disease causation.

2011-07-01

Full Text Available Introduction: Mental retardation is one of the most important problems of general health. The purpose of this study was to evaluate inheritance pattern of mentally retarded patients in Yazd city. Methods: In a descriptive cross- sectional study, all medical records and pedigrees of 320 mentally retarded children whose parents had referred for genetic consultation to the Welfare center of Yazd city were reviewed. Results: Of the total, 62.8% of the parents had consanguineous marriage. Mean inbreeding coefficient of offsprings was 0.0713 in third degree related parents versus 0.0156 in non-related parents. Mental retardation was seen in 43.4% of first– degree relatives of children (6.6% of parents and 36.8% of siblings, respectively. Frequency of mental retardation did not differ significantly in both sexes. Pedigree showed inheritance pattern in 43.4% of patients (autosomal recessive, autosomal dominant and x-linked inheritance pattern were seen in 33.75%, 6.9% and 2.8%, respectively, while 37% of patients had no definite inheritance pattern. Abnormal karyotype were seen in 19.4% of patients, 28 of whom(8.75% of all patients had Down syndrome. The prevalence of autosomal recessive inheritance in patients with consanguineous marriages and non family marriages was 62.8 % and 10%, respectively (P=0. 002. Conclusion: Since multiple cases of mental retardation were seen in families and rate of consanguineous marriage was more in parents of mentally retarded children, genetic counseling in consanguinity marriages and families of mentally retarded children can prevent incidence of mental retardation in these families.

Utilizing inheritance in requirements engineering

Science.gov (United States)

Kaindl, Hermann

1994-01-01

The scope of this paper is the utilization of inheritance for requirements specification, i.e., the tasks of analyzing and modeling the domain, as well as forming and defining requirements. Our approach and the tool supporting it are named RETH (Requirements Engineering Through Hypertext). Actually, RETH uses a combination of various technologies, including object-oriented approaches and artificial intelligence (in particular frames). We do not attempt to exclude or replace formal representations, but try to complement and provide means for gradually developing them. Among others, RETH has been applied in the CERN (Conseil Europeen pour la Rechereche Nucleaire) Cortex project. While it would be impossible to explain this project in detail here, it should be sufficient to know that it deals with a generic distributed control system. Since this project is not finished yet, it is difficult to state its size precisely. In order to give an idea, its final goal is to substitute the many existing similar control systems at CERN by this generic approach. Currently, RETH is also tested using real-world requirements for the Pastel Mission Planning System at ESOC in Darmstadt. First, we outline how hypertext is integrated into a frame system in our approach. Moreover, the usefulness of inheritance is demonstrated as performed by the tool RETH. We then summarize our experiences of utilizing inheritance in the Cortex project. Lastly, RETH will be related to existing work.

The Social Meaning of Inherited Financial Assets. Moral Ambivalences of Intergenerational Transfers

Directory of Open Access Journals (Sweden)

Merlin Schaeffer

2013-11-01

Full Text Available What do inherited financial assets signify to heirs and testators and how does this shape their conduct? Based on grounded theory methodology and twenty open, thematically structured interviews with US heirs, future heirs and testators, this article explicates a theoretical account that proposes a moral ambivalence as the core category to understand the social meaning of inherited financial assets. In particular, the analysis reveals that the social meaning of inherited assets is a contingent, individual compromise between seeing inherited assets as unachieved wealth and seeing them as family means of support. Being the lifetime achievement of another person, inheritances are, on the one hand, morally dubious and thus difficult to appropriate. Yet in terms of family solidarity, inheritances are "family money," which is used when need arises. Taken from this angle, inheriting is not the transfer of one individual's privately held property to another person, but rather the succession of the social status as support-giver along with the resources that belong to this status to the family's next generation. Heirs need to find a personal compromise between these poles, which always leaves room for interpretation. http://nbn-resolving.de/urn:nbn:de:0114-fqs1401131

Statistics from HM Revenue & Customs predict that receipts from inheritance tax will amount to some £3.56 billion in the tax year 2006/07. This compares to £1.68 billion in 1997/98. This paper explores the reason for the large increase in inheritance tax revenues and, in the light of those findings, together with a consideration of the recent public reaction to the changes to the inheritance taxation of trusts announced in the Budget 2006 and incorporated in the Finance Act 2006, argues t...

pleiotropy. It has also been proposed that the survival of long, conserved haplotypes may be due to gestational drive, i.e. selective miscarriage of fetuses who have not inherited the haplotype from a heterozygous mother. Recurrent pregnancy loss (RPL) is defined as three or more consecutive pregnancy losses....... The objective was to test the gestational drive theory for the 8.1AH in women with RPL and their live born children. METHODOLOGY: We investigated the inheritance of the 8.1AH from 82 heterozygous RPL women to 110 live born children. All participants were genotyped for HLA-A, -B and -DRB1 in DNA from EDTA......-treated blood or buccal swaps. Inheritance was compared with a Mendelian inheritance of 50% using a two-sided exact binomial test. RESULTS: We found that 55% of the live born children had inherited the 8.1AH, which was not significantly higher than the expected 50% (P = 0.29). Interestingly, we found a non...

2001-01-01

Inheritance in the expression of amplicons for four microsatellite primer pairs was determined using 10 families created from gametes of wild lake sturgeon (Acipenser fulvescens). Loci Afu34 and Afu68 expressed a maximum of two even-intensity bands per individual and had progeny genotype ratios that fit disomic inheritance (P > 0.05). Some variation exhibited at Afu34 and Afu68 was attributable to a null allele. Genotype expression at both loci also indicated that one female parent had transmitted unreduced gametes. Primer Afu39 amplified products that exhibited four gene doses, where genotype counts fit expected ratios for disomic inheritance (P > 0.05) indicating amplification of products from two disomic loci that share alleles. Meiotic drive was evident at the Afu39 loci based on a test for random segregation (P inheritance based on a single progeny potentially produced by a double reduction gamete. No evidence for proposed octoploid inheritance was observed.

Exome sequencing studies have facilitated the detection of causal genetic variants in yet-unsolved Mendelian diseases. However, the identification of disease causal genes among a list of candidates in an exome sequencing study is still not fully settled, and it is often difficult to prioritize candidate genes for follow-up studies. The inheritance mode provides crucial information for understanding Mendelian diseases, but none of the existing gene prioritization tools fully utilize this information. We examined the characteristics of Mendelian disease genes under different inheritance modes. The results suggest that Mendelian disease genes with autosomal dominant (AD) inheritance mode are more haploinsufficiency and de novo mutation sensitive, whereas those autosomal recessive (AR) genes have significantly more non-synonymous variants and regulatory transcript isoforms. In addition, the X-linked (XL) Mendelian disease genes have fewer non-synonymous and synonymous variants. As a result, we derived a new scoring system for prioritizing candidate genes for Mendelian diseases according to the inheritance mode. Our scoring system assigned to each annotated protein-coding gene (N = 18 859) three pathogenic scores according to the inheritance mode (AD, AR and XL). This inheritance mode-specific framework achieved higher accuracy (area under curve  = 0.84) in XL mode. The inheritance-mode specific pathogenicity prioritization (ISPP) outperformed other well-known methods including Haploinsufficiency, Recessive, Network centrality, Genic Intolerance, Gene Damage Index and Gene Constraint scores. This systematic study suggests that genes manifesting disease inheritance modes tend to have unique characteristics.

La formazione di un’aristocrazia: monache e monasteri femminili a Venezia tra IX e XIII secolo

2014-06-01

Full Text Available This paper examines the processes that shaped the identity of the Venetian aristocracy from the 9th to the 13th centuries and the role played by the relationship between patrician families and some female monasteries. The important female monastery of San Zaccaria and some other nunneries created in the lagoon between the 12th and the 13th centuries are taken into account in the analysis of the formation of Venetian aristocracy from this innovative perspective. By analysing the behaviour of the aristocratic families towards these nunneries, the paper points out how Venetian ruling groups made use of the long-term relationship with nuns as a particularly useful instrument of political competition. The article also shows how some female monasteries were relevant social actors in the process of defi nition of Venetian identity, largely coinciding with their own ruling groups, and in particular with the aristocracy, and with the exercise of power.[it] L’articolo si propone di esaminare il processo di definizione dell’identità del ceto dirigente di Venezia nel periodo IX-XIII secolo e il ruolo occupato dalle relazioni tra le famiglie dell’aristocrazia che costituivano quel ceto e alcuni monasteri femminili. In questa prospettiva, innovativa nell’analisi della formazione dell’aristocrazia di Venezia, si prenderà in esame l’importante monastero femminile di San Zaccaria e si farà inoltre riferimento ad alcuni altri, sorti sulle isole della laguna tra XII e XIII secolo, espressione di un clima religioso e sociale nuovo e particolare. Attraverso l’analisi dei comportamenti adottati dalle famiglie aristocratiche nei confronti di questi monasteri, si dimostra che il ceto dirigente veneziano si servì delle relazioni costanti con le monache come di uno strumento della lotta politica particolarmente utilizzato dalle famiglie dell’aristocrazia della città. Si osserva anche che alcuni monasteri femminili furono a loro volta soggetti attivi

Uncertainty remains on the pathogenetic mechanisms, model of inheritance as well as genotype-phenotype correlation of FMF disease. To investigate the impact of genetic factors on the FMF phenotype and the disease inheritance model. A total of 107 FMF patients were enrolled. Patients were diagnosed clinically. All patients underwent genetic analysis of the FMF locus on 16p13.3. 9 distinct mutations were detected. Specifically, the 85.98% of patients showed a heterozygous genotype. The most common genotypes were p.Met680Ile/wt and p.Met694Val/wt. The most frequent clinical findings were fever, abdominal pain, joint pain, thoracic pain, and erysipelas-like erythema. Analysis of clinical data did not detect any significant difference in clinical phenotype among heterozygous, homozygous as well as compound homozygous subjects, further supporting the evidence that, contrary to the recessive autosomal inheritance, heterozygous patients fulfilled the criteria of clinical FMF. Moreover, subjects with p.Met694Val/wt and p.Met680Ile/wt genotype reported the most severe clinical phenotype. p.Ala744Ser/wt, p.Glu148Gln/Met680Ile, p.Met680Ile/Met680Ile, p.Met680Ile/Met694Val, p.Pro369Ser/wt, p.Met694Ile/wt, p.Glu148Gln/Glu148Gln, p.Lys695Arg/wt resulted in 100% pathogenicity. The existence of a "non classic" autosomal recessive inheritance as well as of an "atypical" dominant autosomal inheritance with incomplete penetrance and variable expressivity cannot be excluded in FMF.

Full Text Available L Otero, L Quintero, D Champsaur, E SimancaPontificia Universidad Javeriana, Bogotá, ColombiaIntroduction: The inheritance of class III malocclusion has been well documented, but the inheritance of craniofacial structures in Colombian families with this malocclusion has been not yet reported.Patients and methods: The study sample of 25 families comprised 186 untreated orthodontic individuals from 8 to 60 years old. Pedigrees were drawn using Cyrillic software. Complete family histories for each proband were ascertained and the affection status of relatives was confirmed by lateral cephalograms and facial and dental photographs. Analysis of variance and odds ratio test for each parameter was performed to estimate inheritance from parents to offspring and to determine similar phenotypic features in relatives.Results: The analysis of the pedigrees suggests autosomal dominant inheritance. The craniofacial characteristics that showed more resemblance between parents and offspring were middle facial height, shorter anterior cranial base and mandibular prognathism. In contrast the protrusion of upper lip and maxillary retrusion were the phenotypic features that contributed to class III in the majority of families.Conclusion: Knowledge of the inheritance of craniofacial phenotypes in class III malocclusion will enable the design of new therapies to treat this malocclusion.Keywords: inheritance, craniofacial, phenotype, class III malocclusion

The study purpose was to contribute to a more complete understanding of the experience and meaning of family inheritance. The aim of this article is to describe and discuss the meaning of communication in inheritance experiences among Canadian families. A constructivist/interpretive methodological approach guided this research. Participants were recruited through purposive, convenience sampling from two cities and one town in southern and southwestern Ontario, Canada. Fifty face-to-face, semi-structured, audio-taped, in-depth interviews were conducted between June 2006 and April 2007. NVivo software was used to organize and analyze the data. A content analysis method guided data analysis. Participants interpreted the meaning of family structure, relationships, feelings, and past inheritance experiences to construct their family inheritance communication. Analysis of the findings revealed four themes regarding the role of communication in family inheritance including: (a) avoiding conflict and preserving biological ties , (b) resisting conversations about possessions , (c) achieving confidence with possession communication , and (d) lasting effects. Participants from non-blended and blended families experienced similar inheritance communication challenges related to past experience with their parents' wills and distribution of their own possessions. Participants with past positive inheritance experiences with parents adopted similar strategies when communicating their own inheritance wishes. Negative messages conveyed to participants by their parent's wills inspired participants to communicate in opposite ways in their own inheritance planning. The study findings are useful for gerontologists, lawyers, family counselors, and estate planners.

Interpreting phenotypic antibiotic tolerance and persister cells as evolution via epigenetic inheritance.

Science.gov (United States)

Day, Troy

2016-04-01

Epigenetic inheritance is the transmission of nongenetic material such as gene expression levels, RNA and other biomolecules from parents to offspring. There is a growing realization that such forms of inheritance can play an important role in evolution. Bacteria represent a prime example of epigenetic inheritance because a large array of cellular components is transmitted to offspring, in addition to genetic material. Interestingly, there is an extensive and growing empirical literature showing that many bacteria can form 'persister' cells that are phenotypically resistant or tolerant to antibiotics, but most of these results are not interpreted within the context of epigenetic inheritance. Instead, persister cells are usually viewed as a genetically encoded bet-hedging strategy that has evolved in response to a fluctuating environment. Here I show, using a relatively simple model, that many of these empirical findings can be more simply understood as arising from a combination of epigenetic inheritance and cellular noise. I therefore suggest that phenotypic drug tolerance in bacteria might represent one of the best-studied examples of evolution under epigenetic inheritance. © 2016 John Wiley & Sons Ltd.

Inherited sterility in insects

Carpenter, J.E.; Marec, F.; Bloem, S.

2005-01-01

The unique genetic phenomena responsible for inherited sterility (IS) in Lepidoptera and some other arthropods, as compared with full sterility, provide advantages for pest control. Lepidopteran females are usually more sensitive to radiation than males of the same species. This allows the radiation dose to be adjusted to suit programme requirements. When partially sterile males mate with wild females, the radiation-induced deleterious effects are inherited by the F 1 generation. As a result, egg hatch is reduced and the resulting offspring are both highly sterile and predominately male. Compared with the high radiation required to achieve full sterility in Lepidoptera, the lower dose of radiation used to induce F 1 sterility increases the quality and competitiveness of the released insects as measured by improved dispersal after release, increased mating ability, and superior sperm competition. F 1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies. In addition, F 1 sterile progeny can be used to increase the production of natural enemies, and to study the potential host and geographical ranges of exotic lepidopteran pests. (author)

Abstract We developed a simple, noninvasive artificial insemination technique to study epigenetic germline inheritance in mice. This technique avoids interfering factors introduced by superovulation, surgery, in vitro culture or mating that can confound the transmission of acquired epigenetic information through the germline. Using a stress model, we demonstrate that our method is suited to test the causal involvement of the male germline in transmitting acquired information from father to offspring. PMID:29492284

Polled animals are valued in cattle industry because the absence of horns has a significant economic impact. However, some cattle are neither polled nor horned but have so-called scurs on their heads, which are corneous growths loosely attached to the skull. A better understanding of the genetic determinism of the scurs phenotype would help to fine map the polled locus. To date, only one study has attempted to map the scurs locus in cattle. Here, we have investigated the inheritance of the scurs phenotype in the French Charolais breed and examined whether the previously proposed localisation of the scurs locus on bovine chromosome 19 could be confirmed or not. Our results indicate that the inheritance pattern of the scurs phenotype in the French Charolais breed is autosomal recessive with complete penetrance in both sexes, which is different from what is reported for other breeds. The frequency of the scurs allele (Sc) reaches 69.9% in the French Charolais population. Eleven microsatellite markers on bovine chromosome 19 were genotyped in 267 offspring (33 half-sib and full-sib families). Both non-parametric and parametric linkage analyses suggest that in the French Charolais population the scurs locus may not map to the previously identified region. A new analysis of an Angus-Hereford and Hereford-Hereford pedigree published in 1978 enabled us to calculate the frequency of the Sc allele in the Hereford breed (89.4%) and to study the penetrance of this allele in males heterozygous for both polled and scurs loci (40%). This led us to revise the inheritance pattern of the scurs phenotype proposed for the Hereford breed and to suggest that allele Sc is not fully but partially dominant in double heterozygous males while it is always recessive in females. Crossbreeding involving the Charolais breed and other breeds gave results similar to those reported in the Hereford breed. Our results suggest the existence of unknown genetics factors modifying the expression of the

Inheritance of evolved clethodim resistance in Lolium rigidum populations from Australia.

2017-08-01

In Australia, the extensive use of clethodim for the control of Lolium rigidum has resulted in the evolution of many clethodim-resistant L. rigidum populations. Five clethodim-resistant populations of L. rigidum were analysed for the inheritance of clethodim resistance. Reciprocal crosses were made between resistant (R) and susceptible (S) populations. Within crosses, dose-responses of reciprocal F 1 families of all populations except A61 were similar to each other, indicating that clethodim resistance in these populations is encoded on the nuclear genome. The level of dominance observed in the dose-response experiments ranged from partial to complete within the herbicide rate used. In the A61 population, within each cross, the response of F 1 from the maternal and paternal parent was different, indicating that resistance is inherited through the female parent. All backcross populations segregated in a different manner. Only one population, FP, fitted a single-gene model (1:1). Two populations fitted two-gene models: a 3:1 inheritance model for F4 and a 1:3 inheritance model for A91. For population E2, no clear pattern of inheritance was determined, suggesting more complex inheritance. The results of this study indicate that different patterns of clethodim resistance in L. rigidum exist. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Most medical practice managers who take a new job will inherit an existing team. Those first few days on the job are critical because they can determine whether or not the new manager will succeed. This article provides a game plan for new medical practice managers so they get off on the right foot with their inherited teams. It suggests strategies for learning about the team's culture and for demonstrating visibly that there is a new manager in the job. It offers guidelines about introducing the new manager to the inherited team, discussing past experiences, and establishing new expectations. This article further provides practical tips for serving as a role model, gaining allies, and dealing with troublemakers quickly and effectively. It suggests strategies for speaking about the previous practice manager and for creating excitement with the inherited team. Finally, this article offers a set of 15 questions a new manager can ask members of the inherited team to get to know them, an additional 25-point team assessment instrument, and a step-by-step strategy for raising the bar for mediocre, lackluster, or dysfunctional inherited teams.

The Legal Position and Factual Situation of Women Participation to Inheritance in Kosovo

Full Text Available The right to inheritance represents one of the basic human rights. As such this right is regulated by the law. The Law on Inheritance in Kosovo regulates substantially, all the issues related to inheritance. In this context, this Law contains numerous rules that proclaim full equality of women with men to inheritance. Regardless of equality proclaimed by law practical reality of life indicates a different situation. This reality proves that women participation to inheritance nevertheless is very small. The reasons for this situation are numerous and diverse, but mostly they have to deal with the still existence in people's conscience of many customary rules, which constantly treated women as a subject of second hand. In this article a modest attempt is made to reflect besides legal aspect also the practical situation indicating the degree of women participation to inheritance in Kosovo, in all grades that she may appear as heir.

THE CORRELATION BETWEEN THE INHERITED DEBT AND THE RIGHT OF OPTION ON SUCCESSION

Directory of Open Access Journals (Sweden)

Ana-Maria GHERGHINA (VASILE

2015-07-01

Full Text Available A natural person’s patrimony consists, apart from rights (assets of the succession, of a liabilities side as well related to obligations that the patrimony’s holder bequeaths onto the heirs following his/her death. The succession implies that there are two parties, i.e. the assets of the succession and the inherited debt. The inherited debt is mainly made up of the inheritance duties and liabilities. The main components of the inherited debt are the debts the deceased has left, following that the duties shall be the obligations arising out after the succession will be opened. However, without defining the inherited debt concept in the specialized literature, successional liabilities have been considered to mean those patrimonial obligations of the deceased toward a third party or the inheritors existing in the successional patrimony on the opening of succession, regardless of their origin (contractual, tortious or legal. Inheritance duties refer to those obligations which did not exist in the de cujus patrimony, but come into existence devolving upon the heirs on the date of succession’s opening or subsequently after that time, either in consequence of the deceased’s desire, or independently of it. The main characteristic of the option on succession is that the right of option belongs exclusively to the presumptive heirs. From this point of view, the option on succession seems to have nothing in common with the inherited debt. Nevertheless, I intend to analyse the correlation between the two institutions from the perspective of the place inheritance creditors hold in the totality of rights of option. Their presence is only justified when there is an inherited debt.

Although researchers have proposed various data mining models for biomedical approaches, there remains a challenge in accurately determining the responsible genetic factors for prioritizing the single nucleotide polymorphisms (SNP) associated with the disease. In this commentary, we review the state-of-art data mining and pattern r...

Mitochondria are predominantly inherited from the maternal gamete, even in unicellular organisms. Yet an extraordinary array of mechanisms enforce uniparental inheritance, which implies shifting selection pressures and multiple origins. We consider how this high turnover in mechanisms controlling uniparental inheritance arises using a novel evolutionary model in which control of mitochondrial transmission occurs either during spermatogenesis (by paternal nuclear genes) or at/after fertilization (by maternal nuclear genes). The model treats paternal leakage as an evolvable trait. Our evolutionary analysis shows that maternal control consistently favours strict uniparental inheritance with complete exclusion of sperm mitochondria, whereas some degree of paternal leakage of mitochondria is an expected outcome under paternal control. This difference arises because mito-nuclear linkage builds up with maternal control, allowing the greater variance created by asymmetric inheritance to boost the efficiency of purifying selection and bring benefits in the long term. In contrast, under paternal control, mito-nuclear linkage tends to be much weaker, giving greater advantage to the mixing of cytotypes, which improves mean fitness in the short term, even though it imposes a fitness cost to both mating types in the long term. Sexual conflict is an inevitable outcome when there is competition between maternal and paternal control of mitochondrial inheritance. If evolution has led to complete uniparental inheritance through maternal control, it creates selective pressure on the paternal nucleus in favour of subversion through paternal leakage, and vice versa. This selective divergence provides a reason for the repeated evolution of novel mechanisms that regulate the transmission of paternal mitochondria, both in the fertilized egg and spermatogenesis. Our analysis suggests that the widespread occurrence of paternal leakage and prevalence of heteroplasmy are natural outcomes of

In cytoplasmic inheritance, structural states of a parent cell could be transmitted to offspring cells via two mechanisms. The first is referred to as the hangover of parent structure, where the structure itself remains and faithfully transmits within offspring cells; the second is structural inheritance, wherein the parent structure functions as a template for development of new offspring structure. We estimated to what extent the parent structure affects the development of offspring structure by structural inheritance, using a clone of the diatom Cyclotella meneghiniana The cell has two siliceous valves (a cell wall part at both cell poles): one is inherited from the parent and the other is newly formed. We estimated cytoplasmic heritability by comparing valve traits (central fultoportulae (CTFP), striae, central area, and cell diameter) of parent and new offspring valves, using single-cell isolation and valve labelling. Parent-offspring valve trait regressions showed that all traits, except CTFP, were significantly correlated. We formulated a quantitative genetic model considering the diatom inheritance system and revealed short-term rapid evolution compared with other inheritance systems. Diatom structural inheritance will have evolved to enable clonal populations to rapidly acquire and maintain suitable structures for temporal changes in environments and life-cycle stages. © 2016 The Author(s).

2014-12-15

The currently widespread use of neuroimaging has led neurologists to often face the problem of the differential diagnosis of white matter diseases. There are various forms of leukoencephalopathies (vascular, inflammatory and immunomediated, infectious, metabolic, neoplastic) and sometimes white matter lesions are expression of a genetic disease. While many inherited leukoencephalopathies fall in the child neurologist's interest, others may have a delayed or even a typical onset in the middle or old age. This field is rapidly growing and, in the last few years, many new inherited white matter diseases have been described and genetically defined. A non-delayed recognition of middle and old age inherited leukoencephalopathies appears important to avoid unnecessary tests and therapies in the patient and to possibly anticipate the diagnosis in relatives. The aim of this review is to provide a guide to direct the diagnostic process when facing a patient with a suspicion of an inherited form of leukoencephalopathy and with clinical onset in middle or old age. Based on a MEDLINE search from 1990 to 2013, we identified 24 middle and old age onset inherited leukoencephalopathies and reviewed in this relation the most recent findings focusing on their differential diagnosis. We provide summary tables to use as a check list of clinical and neuroimaging findings that are most commonly associated with these forms of leukoencephalopathies. When present, we reported specific characteristics of single diseases. Several genetic diseases may be suspected in patients with middle or old age and white matter abnormalities. In only few instances, pathognomonic clinical or associated neuroimaging features help identifying a specific disease. Therefore, a comprehensive knowledge of the characteristics of these inherited white matter diseases appears important to improve the diagnostic work-up, optimize the choice of genetic tests, increase the number of diagnosed patients, and stimulate

The double pedigree: a method for studying culturally and genetically inherited behavior in tandem.

Directory of Open Access Journals (Sweden)

Etienne Danchin

Full Text Available Transgenerational sources of biological variation have been at the center of evolutionary studies ever since Darwin and Wallace identified natural selection. This is because evolution can only operate on traits whose variation is transmitted, i.e. traits that are heritable. The discovery of genetic inheritance has led to a semantic shift, resulting in the tendency to consider that only genes are inherited across generations. Today, however, concepts of heredity are being broadened again to integrate the accruing evidence of non-genetic inheritance, and many evolutionary biologists are calling for the inclusion of non-genetic inheritance into an inclusive evolutionary synthesis. Here, we focus on social heredity and its role in the inheritance of behavioral traits. We discuss quantitative genetics methods that might allow us to disentangle genetic and non-genetic transmission in natural populations with known pedigrees. We then propose an experimental design based on cross-fostering among animal cultures, environments and families that has the potential to partition inherited phenotypic variation into socially (i.e. culturally and genetically inherited components. This approach builds towards a new conceptual framework based on the use of an extended version of the animal model of quantitative genetics to integrate genetic and cultural components of behavioral inheritance.

Intracranial hemorrhage in congenital bleeding disorders.

: Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death. This bleeding feature can also be observed in grey platelet syndrome, though less frequently than in Glanzmann's thrombasthenia. In hemophilia, intracerebral hemorrhage is affected by various risk factors one of which is the severity of the disease. The precise prevalence of ICH in these patients is not clear but an estimated incidence of 3.5-4% among newborns with hemophilia is largely ascertained. Although ICH is a rare phenomenon in CBDs, it can be experienced by every patient with severe hemophilia A and B, FXIII deficiency (FXIIID), FVIID, FXD, FVD, FIID, and afibrinogenemia. Upon observing the general signs and symptoms of ICH such as vomiting, seizure, unconsciousness, and headache, appropriate replacement therapies and cranial ultrasound scans must be done to decrease ICH-related morbidity and mortality.

Over the last few decades, pyrethroid-resistant in Triatoma infestans populations have been reported, mainly on the border between Argentina and Bolivia. Understanding the genetic basis of inheritance mode and heritability of resistance to insecticides under laboratory conditions is crucial for vector management and monitoring of insecticide resistance. Currently, few studies have been performed to characterize the inheritance mode of resistance to pyrethroids in T. infestans; for this reason, the present study aims to characterize the inheritance and heritability of deltamethrin resistance in T. infestans populations from Bolivia with different toxicological profiles. Experimental crosses were performed between a susceptible (S) colony and resistant (R) and reduced susceptibility (RS) colonies in both directions (♀ x ♂ and ♂ x ♀), and inheritance mode was determined based on degree of dominance (DO) and effective dominance (D(ML)). In addition, realized heritability (h(2)) was estimated based on a resistant colony, and select pressure was performed for two generations based on the diagnostic dose (10 ng. i. a. /nymph). The F1 progeny of the experimental crosses and the selection were tested by a standard insecticide resistance bioassay. The result for DO and D(ML) (Bolivia. The lethal doses (LD50) increase from one generation to another rapidly after selection pressure with deltamethrin. This suggests that resistance is an additive and cumulative factor, mainly in highly structured populations with limited dispersal capacity, such as T. infestans. This phenomenon was demonstrated for the first time for T. infestans in the present study. These results are very important for vector control strategies in problematic areas where high resistance ratios of T. infestans have been reported.

This contribution addresses the substantial tax subsidies for businesses introduced by the German Inheritance Tax Act 2009. Advocates in favour of the vast or even entire tax exemption for businesses stress the potential damage of the inheritance tax on businesses, as those often lack liquid assets to meet tax liability. This submission tackles this issue empirically based on data of the German Inheritance Tax Statistics and the SOEP. The results indicate that former German inheritance tax la...

The Magmatic Budget of Rifted Margins: is it Related to Inheritance?

Science.gov (United States)

Manatschal, G.; Tugend, J.; Gillard, M.; Sauter, D.

2017-12-01

High quality reflection and refraction seismic surveys show a divergent style of margin architecture often referred to as magma-poor or magma-rich. More detailed studies show, however, that the evolution of these margins can be similar, despite the variable quantity and distribution of magmatism. These observations suggest that simple relations between magmatic and extensional systems are inappropriate to describe the magmatic history of rifted margins. Moreover, the study of magmatic additions indicates that they may occur, prior to, during or after lithospheric breakup. Furthermore, the observation that the magmatic budget may change very abruptly along strike and across the margin is difficult to reconcile with the occurrence of plumes or other deep-seated large-scale mantle phenomena only. These overall observations result in questions on how magmatic and tectonic processes are interacting during rifting and lithospheric breakup and on how far the inherited composition and temperature of the decompressing mantle may control the magmatic budget during rifting. In our presentation we will review examples from present-day and fossil rifted margins to discuss their structural and magmatic evolution and whether they are considered as magma-rich or magma-poor. The key questions that we aim to address are: 1) whether decompression melting is the driving force, or rather the consequence of extension, 2) how far the magmatic budget is controlled by inherited mantle composition and temperature, and 3) how important magma storage is during initial stages of rifting. Eventually, we will discuss to what extent the evolution of margins may reflect the interplay between inheritance (innate/"genetic code") and the actual physical processes (acquired/external factors).

Identifying loci with parental differences in DNA methylation is key to unraveling parent-of-origin phenotypes. By conducting a MeDIP-Seq screen in maternal-methylation free postimplantation mouse embryos (Dnmt3L-/+), we demonstrate that maternal-specific methylation exists very scarcely at midgestation. We reveal two forms of oocyte-specific methylation inheritance: limited to preimplantation, or with longer duration, i.e. maternally imprinted loci. Transient and imprinted maternal germline DMRs (gDMRs) are indistinguishable in gametes and preimplantation embryos, however, de novo methylation of paternal alleles at implantation delineates their fates and acts as a major leveling factor of parent-inherited differences. We characterize two new imprinted gDMRs, at the Cdh15 and AK008011 loci, with tissue-specific imprinting loss, again by paternal methylation gain. Protection against demethylation after fertilization has been emphasized as instrumental in maintaining parent-of-origin methylation inherited from the gametes. Here we provide evidence that protection against de novo methylation acts as an equal major pivot, at implantation and throughout life. Copyright © 2012 Elsevier Inc. All rights reserved.

The extreme ultraviolet (EUV) spectral region (ca. 20--300 Å) is rich in emission lines from low- to mid-Z ions, particularly from the middle charge states of iron. Many of these emission lines are important diagnostics for astrophysical plasmas, providing information on properties such as elemental abundance, temperature, density, and even magnetic field strength. In recent years, strides have been made to understand the complexity of the atomic levels of the ions that emit the lines that contribute to the richness of the EUV region. Laboratory measurements have been made to verify and benchmark the lines. Here, we present laboratory measurements of Fe XI, Fe XII, and Fe XIII between 40-140 Å. The measurements were made at the Lawrence Livermore electron beam ion trap (EBIT) facility, which has been optimized for laboratory astrophysics, and which allows us to select specific charge states of iron to help line identification. We also present new calculations by the Hebrew University - Lawrence Livermore Atomic Code (HULLAC), which we also utilized for line identification. We found that HULLAC does a creditable job of reproducing the forest of lines we observed in the EBIT spectra, although line positions are in need of adjustment, and line intensities often differed from those observed. We identify or confirm a number of new lines for these charge states. This work was supported by the NASA Solar and Heliospheric Program under Contract NNH10AN31I and the DOE General Plasma Science program.

Christopher R

1999-01-01

Full Text Available The past two decades have witnessed a rapid increase in the knowledge of the inherited neurometabolic disorders. The precise diagnosis of these disorders which is a challenge to the physician can be best accomplished by biochemical methods. Screening of clinically selected patients with simple chemical urine tests and routine blood chemistry investigations followed by measurement of specific metabolites and assay of the relevant enzymes confirms the diagnosis in most cases. Biochemical diagnosis of inherited neurometabolic disorders although expensive is rapid and confirmatory and therefore aids in treatment and further prevention of these rare disorders.

Role of epigenetics in developmental biology and transgenerational inheritance.

Science.gov (United States)

Skinner, Michael K

2011-03-01

The molecular mechanisms involved in developmental biology and cellular differentiation have traditionally been considered to be primarily genetic. Environmental factors that influence early life critical windows of development generally do not have the capacity to modify genome sequence, nor promote permanent genetic modifications. Epigenetics provides a molecular mechanism for environment to influence development, program cellular differentiation, and alter the genetic regulation of development. The current review discusses how epigenetics can cooperate with genetics to regulate development and allow for greater plasticity in response to environmental influences. This impacts area such as cellular differentiation, tissue development, environmental induced disease etiology, epigenetic transgenerational inheritance, and the general systems biology of organisms and evolution.

Polydactyly in Development, Inheritance, and Evolution.

Science.gov (United States)

Lange, Axel; Müller, Gerd B

2017-03-01

The occurrence of supernumerary digits or toes in humans and other tetrapods has attracted general interest since antiquity and later influenced scientific theories of development, inheritance, and evolution. Seventeenth-century genealogical studies of polydactyly were at the beginning of an understanding of the rules of inheritance. Features of polydactyly were also part of the classical disputes on the nature of development, including the preformation-versus-epigenesis and the atavism-versus-malformation debates. In the evolutionary domain, polydactyly was used in the criticism of the gradualist account of variation underlying Darwin’s theory. Today, extra digit formation plays a role in the conceptualization of gene regulation and pattern formation in vertebrate limb evolution. Recent genetic, experimental, and modeling accounts of extra digit formation highlight the existence of nongradual transitions in phenotypic states, suggesting a distinction between continuous and discontinuous variation in evolution.

Channelopathies - Emerging Trends in The Management of Inherited Arrhythmias

Priya Chockalingam, MBBS, MRCPCH, PhD

2015-01-01

Full Text Available In spite of their relative rarity, inheritable arrhythmias have come to the forefront as a group of potentially fatal but preventable cause of sudden cardiac death in children and (young adults. Comprehensive management of inherited arrhythmias includes diagnosing and treating the proband and identifying and protecting affected family members. This has been made possible by the vast advances in the field of molecular biology enabling better understanding of the genetic underpinnings of some of these disease groups, namely congenital long QT syndrome, catecholaminergic polymorphic ventricular tachycardia and Brugada syndrome. The ensuing knowledge of the genotype-phenotype correlations enables us to risk-stratify, prognosticate and treat based on the genetic test results. The various diagnostic modalities currently available to us, including clinical tools and genetic technologies, have to be applied judiciously in order to promptly identify those affected and to spare the emotional burden of a potentially lethal disease in the unaffected individuals. The therapeutic armamentarium of inherited arrhythmias includes pharmacological agents, device therapies and surgical interventions. A treatment strategy keeping in mind the risk profile of the patients, the local availability of drugs and the expertise of the treating personnel is proving effective. While opportunities for research are numerous in this expanding field of medicine, there is also tremendous scope for incorporating the emerging trends in managing patients and families with inherited arrhythmias in the Indian subcontinent.

A second inheritance system: the extension of biology through culture.

Science.gov (United States)

Whiten, Andrew

2017-10-06

By the mid-twentieth century (thus following the 'Modern Synthesis' in evolutionary biology), the behavioural sciences offered only the sketchy beginnings of a scientific literature documenting evidence for cultural inheritance in animals-the transmission of traditional behaviours via learning from others (social learning). By contrast, recent decades have seen a massive growth in the documentation of such cultural phenomena, driven by long-term field studies and complementary laboratory experiments. Here, I review the burgeoning scope of discoveries in this field, which increasingly suggest that this 'second inheritance system', built on the shoulders of the primary genetic inheritance system, occurs widely among vertebrates and possibly in invertebrates too. Its novel characteristics suggest significant implications for our understanding of evolutionary biology. I assess the extent to which this second system extends the scope of evolution, both by echoing principal properties of the primary, organic evolutionary system, and going beyond it in significant ways. This is well established in human cultural evolution; here, I address animal cultures more generally. The further major, and related, question concerns the extent to which the consequences of widespread animal cultural transmission interact with the primary, genetically based inheritance systems, shaping organic evolution.

Inherited disorders of brain neurotransmitters: pathogenesis and diagnostic approach.

Szymańska, Krystyna; Kuśmierska, Katarzyna; Demkow, Urszula

2015-01-01

Neurotransmitters (NTs) play a central role in the efficient communication between neurons necessary for normal functioning of the nervous system. NTs can be divided into two groups: small molecule NTs and larger neuropeptide NTs. Inherited disorders of NTs result from a primary disturbance of NTs metabolism or transport. This group of disorders requires sophisticated diagnostic procedures. In this review we discuss disturbances in the metabolism of tetrahydrobiopterin, biogenic amines, γ-aminobutyric acid, foliate, pyridoxine-dependent enzymes, and also the glycine-dependent encephalopathy. We point to pathologic alterations of proteins involved in synaptic neurotransmission that may cause neurological and psychiatric symptoms. We postulate that synaptic receptors and transporter proteins for neurotransmitters should be investigated in unresolved cases. Patients with inherited neurotransmitters disorders present various clinical presentations such as mental retardation, refractory seizures, pyramidal and extrapyramidal syndromes, impaired locomotor patterns, and progressive encephalopathy. Every patient with suspected inherited neurotransmitter disorder should undergo a structured interview and a careful examination including neurological, biochemical, and imaging.

Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or 'gentes') in avian brood parasites. Here we report the first unambiguous evidence for maternal inheritance of egg colouration in the brood-parasitic common cuckoo Cuculus canorus. Females laying blue eggs belong to an ancient (∼2.6 Myr) maternal lineage, as evidenced by both mitochondrial and W-linked DNA, but are indistinguishable at nuclear DNA from other common cuckoos. Hence, cuckoo host races with blue eggs are distinguished only by maternally inherited components of the genome, which maintain host-specific adaptation despite interbreeding among males and females reared by different hosts. A mitochondrial phylogeny suggests that blue eggs originated in Asia and then expanded westwards as female cuckoos laying blue eggs interbred with the existing European population, introducing an adaptive trait that expanded the range of potential hosts.

Clinical Characteristics and Current Therapies for Inherited Retinal Degenerations

Sahel, José-Alain; Marazova, Katia; Audo, Isabelle

2015-01-01

Inherited retinal degenerations (IRDs) encompass a large group of clinically and genetically heterogeneous diseases that affect approximately 1 in 3000 people (>2 million people worldwide) (Bessant DA, Ali RR, Bhattacharya SS. 2001. Molecular genetics and prospects for therapy of the inherited retinal dystrophies. Curr Opin Genet Dev 11: 307–316.). IRDs may be inherited as Mendelian traits or through mitochondrial DNA, and may affect the entire retina (e.g., rod–cone dystrophy, also known as retinitis pigmentosa, cone dystrophy, cone–rod dystrophy, choroideremia, Usher syndrome, and Bardet-Bidel syndrome) or be restricted to the macula (e.g., Stargardt disease, Best disease, and Sorsby fundus dystrophy), ultimately leading to blindness. IRDs are a major cause of severe vision loss, with profound impact on patients and society. Although IRDs remain untreatable today, significant progress toward therapeutic strategies for IRDs has marked the past two decades. This progress has been based on better understanding of the pathophysiological pathways of these diseases and on technological advances. PMID:25324231

MET-2-Dependent H3K9 Methylation Suppresses Transgenerational Small RNA Inheritance.

In C. elegans, alterations to chromatin produce transgenerational effects, such as inherited increase in lifespan and gradual loss of fertility. Inheritance of histone modifications can be induced by double-stranded RNA-derived heritable small RNAs. Here, we show that the mortal germline phenotype, which is typical of met-2 mutants, defective in H3K9 methylation, depends on HRDE-1, an argonaute that carries small RNAs across generations, and is accompanied by accumulated transgenerational misexpression of heritable small RNAs. We discovered that MET-2 inhibits small RNA inheritance, and, as a consequence, induction of RNAi in met-2 mutants leads to permanent RNAi responses that do not terminate even after more than 30 generations. We found that potentiation of heritable RNAi in met-2 animals results from global hyperactivation of the small RNA inheritance machinery. Thus, changes in histone modifications can give rise to drastic transgenerational epigenetic effects, by controlling the overall potency of small RNA inheritance. Copyright © 2017 Elsevier Ltd.

Recent studies on human disease have revealed that aberrant interaction between proteins probably underlies a substantial number of human genetic diseases. This suggests a need to investigate disease inheritance mode using interaction, and based on which to refresh our conceptual understanding of a series of properties regarding inheritance mode of human disease. We observed a strong correlation between the number of protein interactions and the likelihood of a gene causing any dominant diseases or multiple dominant diseases, whereas no correlation was observed between protein interaction and the likelihood of a gene causing recessive diseases. We found that dominant diseases are more likely to be associated with disruption of important interactions. These suggest inheritance mode should be understood using protein interaction. We therefore reviewed the previous studies and refined an interaction model of inheritance mode, and then confirmed that this model is largely reasonable using new evidences. With these findings, we found that the inheritance mode of human genetic diseases can be predicted using protein interaction.

The genetics of suicide is increasingly recognized and relevant for mental health literacy, but actual beliefs may lag behind current knowledge. We examined such beliefs in student samples (total N = 686) from Estonia, Malaysia, Romania, the United Kingdom, and the United States with the Beliefs in the Inheritance of Risk Factors for Suicide Scale. Cultural effects were small, those of key demographics nil. Several facets of construct validity were demonstrated. Marked differences in perceived plausibility of evidence about the genetics of suicide according to research design, observed in all samples, may be of general interest for investigating lay theories of abnormal behavior and communicating behavioral and psychiatric genetic research findings.

Orogenic structural inheritance and rifted passive margin formation

Science.gov (United States)

Salazar Mora, Claudio A.; Huismans, Ritske S.

2016-04-01

Structural inheritance is related to mechanical weaknesses in the lithosphere due to previous tectonic events, e.g. rifting, subduction and collision. The North and South Atlantic rifted passive margins that formed during the breakup of Western Gondwana, are parallel to the older Caledonide and the Brasiliano-Pan-African orogenic belts. In the South Atlantic, 'old' mantle lithospheric fabric resulting from crystallographic preferred orientation of olivine is suggested to play a role during rifted margin formation (Tommasi and Vauchez, 2001). Magnetometric and gravimetric mapping of onshore structures in the Camamu and Almada basins suggest that extensional faults are controlled by two different directions of inherited older Brasiliano structures in the upper lithosphere (Ferreira et al., 2009). In the South Atlantic Campos Basin, 3D seismic data indicate that inherited basement structures provide a first order control on basin structure (Fetter, 2009). Here we investigate the role of structural inheritance on the formation of rifted passive margins with high-resolution 2D thermo-mechanical numerical experiments. The numerical domain is 1200 km long and 600 km deep and represents the lithosphere and the sublithospheric mantle. Model experiments were carried out by creating self-consistent orogenic inheritance where a first phase of orogen formation is followed by extension. We focus in particular on the role of varying amount of orogenic shortening, crustal rheology, contrasting styles of orogen formation on rifted margin style, and the time delay between orogeny and subsequent rifted passive formation. Model results are compared to contrasting structural styles of rifted passive margin formation as observed in the South Atlantic. Ferreira, T.S., Caixeta, J.M., Lima, F.D., 2009.

Along with the development of human civilization in Indonesia, the changes and reform of Islamic inheritance law so as to conform to the conditions and culture cannot be denied. The distribution of inheritance in Indonesia can be done automatically by storing the rule of Islamic inheritance law in the expert system. In this study, we analyze the knowledge of experts in Islamic inheritance in Indonesia and represent it in the form of rules using rule-based Forward Chaining (FC) and Davis-Putman-Logemann-Loveland (DPLL) algorithms. By hybridizing FC and DPLL algorithms, the rules of Islamic inheritance law in Indonesia are clearly defined and measured. The rules were conceptually validated by some experts in Islamic laws and informatics. The results revealed that generally all rules were ready for use in an expert system.

Inheritable and sporadic non-autoimmune hyperthyroidism.

Science.gov (United States)

Ferraz, Carolina; Paschke, Ralf

2017-03-01

Hyperthyroidism is a clinical state that results from high thyroid hormone levels which has multiple etiologies, manifestations, and potential therapies. Excluding the autoimmune Graves disease, autonomic adenomas account for the most import cause of non-autoimmune hyperthyroidism. Activating germline mutations of the TSH receptor are rare etiologies for hyperthyroidism. They can be inherited in an autosomal dominant manner (familial or hereditary, FNAH), or may occur sporadically as a de novo condition, also called: persistent sporadic congenital non-autoimmune hyperthyroidism (PSNAH). These three conditions: autonomic adenoma, FNAH and PSNAH constitute the inheritable and sporadic non-autoimmune hyperthyroidism. Particularities in epidemiology, etiology, molecular and clinical aspects of these three entities will be discussed in this review in order to guide to an accurate diagnosis allowing among others genetic counseling and presymptomatic diagnosis for the affected families. The optimal treatment based on the right diagnosis will avoid consequences of a persistent or relapsing hyperthyroidism. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Online Mendelian Inheritance In Man (OMIM) is a public database of bibliographic information about human genes and genetic disorders. Begun by Dr. Victor McKusick as the authoritative reference Mendelian Inheritance in Man, it is now distributed electronically by the National Center for Biotechnology Information (NCBI). Material in OMIM is derived from the biomedical literature and is written by Dr. McKusick and his colleagues at Johns Hopkins University and elsewhere. Each OMIM entry has a full text summary of a genetic phenotype and/or gene and has copious links to other genetic resources such as DNA and protein sequence, PubMed references, mutation databases, approved gene nomenclature, and more. In addition, NCBI's neighboring feature allows users to identify related articles from PubMed selected on the basis of key words in the OMIM entry. Through its many features, OMIM is increasingly becoming a major gateway for clinicians, students, and basic researchers to the ever-growing literature and resources of human genetics.

The role of non-genetic inheritance in evolutionary rescue: epigenetic buffering, heritable bet hedging and epigenetic traps.

Science.gov (United States)

O'Dea, Rose E; Noble, Daniel W A; Johnson, Sheri L; Hesselson, Daniel; Nakagawa, Shinichi

2016-01-01

Rapid environmental change is predicted to compromise population survival, and the resulting strong selective pressure can erode genetic variation, making evolutionary rescue unlikely. Non-genetic inheritance may provide a solution to this problem and help explain the current lack of fit between purely genetic evolutionary models and empirical data. We hypothesize that epigenetic modifications can facilitate evolutionary rescue through 'epigenetic buffering'. By facilitating the inheritance of novel phenotypic variants that are generated by environmental change-a strategy we call 'heritable bet hedging'-epigenetic modifications could maintain and increase the evolutionary potential of a population. This process may facilitate genetic adaptation by preserving existing genetic variation, releasing cryptic genetic variation and/or facilitating mutations in functional loci. Although we show that examples of non-genetic inheritance are often maladaptive in the short term, accounting for phenotypic variance and non-adaptive plasticity may reveal important evolutionary implications over longer time scales. We also discuss the possibility that maladaptive epigenetic responses may be due to 'epigenetic traps', whereby evolutionarily novel factors (e.g. endocrine disruptors) hack into the existing epigenetic machinery. We stress that more ecologically relevant work on transgenerational epigenetic inheritance is required. Researchers conducting studies on transgenerational environmental effects should report measures of phenotypic variance, so that the possibility of both bet hedging and heritable bet hedging can be assessed. Future empirical and theoretical work is required to assess the relative importance of genetic and epigenetic variation, and their interaction, for evolutionary rescue.

2002-01-01

A gamma ray induced fascination mutation was isolated from sunflower variety Surya. Morphological traits and inheritance pattern of the mutant were studied. Fascination mutation was the manifestation of enlarged shoot apex, smaller and more number of leaves with irregular leaf arrangements, significantly higher leaf area and leaf biomass, flattened stem and low seed yield than the parent variety. Inheritance studies indicated that fascination was governed by a single recessive nuclear gene, which may be responsible for the disturbed differentiation of stem and leaves during developmental stages of plant growth [it

With all the above condition,the innovation and development of acupuncture-moxibustion could be better achieved.

THE ELUCIDATION OF STRESS MEMORY INHERITANCE IN BRASSICA RAPA PLANTS

Directory of Open Access Journals (Sweden)

Andriy eBilichak

2015-01-01

Full Text Available Plants are able to maintain the memory of stress exposure throughout their ontogenesis and faithfully propagate it into the next generation. Recent evidence argues for the epigenetic nature of this phenomenon. Small RNAs (smRNAs are one of the vital epigenetic factors because they can both affect gene expression at the place of their generation and maintain non-cell-autonomous gene regulation. Here, we have made an attempt to decipher the contribution of smRNAs to the heat-shock-induced transgenerational inheritance in Brassica rapa plants using sequencing technology. To do this, we have generated comprehensive profiles of a transcriptome and a small RNAome (smRNAome from somatic and reproductive tissues of stressed plants and their untreated progeny. We have demonstrated that the highest tissue-specific alterations in the transcriptome and smRNAome profile are detected in tissues that were not directly exposed to stress, namely, in the endosperm and pollen. Importantly, we have revealed that the progeny of stressed plants exhibit the highest fluctuations at the smRNAome level but not at the transcriptome level. Additionally, we have uncovered the existence of heat-inducible and transgenerationally transmitted tRNA-derived small RNA fragments in plants. Finally, we suggest that miR168 and braAGO1 are involved in the stress-induced transgenerational inheritance in plants.

Inheritance Law between Common and Civil Law - As exemplified by life-long support contracts

Directory of Open Access Journals (Sweden)

Jadranka Đorđević-Crnobrnja

2016-02-01

Full Text Available The dualism between common law and civil law in Serbia has been examined in theoretical and factographical ethnological and legal literature, yet this problem in the sphere of inheritance law has been considered mostly within the context of inequality between the sexes in matters of inheritance. As a result, the question of the connection between life-long support contracts and inheritance remains unexplored, despite the fact that through the analysis of inheritance practices based on this kind of contract the influence of socio-cultural mechanisms on the institution of inheritance can be clearly observed. These insights, together with the fact that a dualism and parallelism of civil and common have existed in Serbia for more than a century, have inspired an analysis of life-long support contracts in order to problematize the relation between common law and civil law in practice.

Paternal inheritance in mealybugs (Hemiptera: Coccoidea: Pseudococcidae)

Science.gov (United States)

Kol-Maimon, Hofit; Mendel, Zvi; Franco, José Carlos; Ghanim, Murad

2014-10-01

Mealybugs have a haplodiploid reproduction system, with paternal genome elimination (PGE); the males are diploid soon after fertilization, but during embryogenesis, the male paternal set of chromosomes becomes heterochromatic (HC) and therefore inactive. Previous studies have suggested that paternal genes can be passed on from mealybug males to their sons, but not necessarily by any son, to the next generation. We employed crosses between two mealybug species— Planococcus ficus (Signoret) and Planococcus citri (Risso)—and between two populations of P. ficus, which differ in their mode of pheromone attraction, in order to demonstrate paternal inheritance from males to F2 through F1 male hybrids. Two traits were monitored through three generations: mode of male pheromone attraction (pherotype) and sequences of the internal transcribed spacer 2 (ITS2) gene segment (genotype). Our results demonstrate that paternal inheritance in mealybugs can occur from males to their F2 offspring, through F1 males (paternal line). F2 backcrossed hybrid males expressed paternal pherotypes and ITS2 genotypes although their mother originated through a maternal population. Further results revealed other, hitherto unknown, aspects of inheritance in mealybugs, such as that hybridization between the two species caused absence of paternal traits in F2 hybrid females produced by F1 hybrid females. Furthermore, hybridization between the two species raised the question of whether unattracted males have any role in the interactions between P. ficus and P. citri.

Environmentally induced epigenetic transgenerational inheritance of disease susceptibility.

Science.gov (United States)

Nilsson, Eric E; Skinner, Michael K

2015-01-01

Environmental insults, such as exposure to toxicants or nutritional abnormalities, can lead to epigenetic changes that are in turn related to increased susceptibility to disease. The focus of this review is on the transgenerational inheritance of such epigenetic abnormalities (epimutations), and how it is that these inherited epigenetic abnormalities can lead to increased disease susceptibility, even in the absence of continued environmental insult. Observations of environmental toxicant specificity and exposure-specific disease susceptibility are discussed. How epimutations are transmitted across generations and how epigenetic changes in the germline are translated into an increased disease susceptibility in the adult is reviewed with regard to disease etiology.

Bastida Bermejo, José María; Hernández-Rivas, Jesús María; González-Porras, José Ramón

2017-01-20

Inherited platelet disorders diagnosis is based on the clinical history and bleeding assessment tools. The laboratory functional assays as well as the molecular test to identify the pathogenic genetic variant are essential to confirm the accurate diagnosis of these disorders. Nowadays, the main challenges to developing a new diagnostic system are involved in reducing the samples' volume, and faster and more helpful analysis. Moreover, there are no widely available and standardised global tests. High throughput genetic testing such as next-generation sequencing has revolutionised DNA sequencing technologies as it allows the simultaneous and faster investigation of multiple genes at a manageable cost. This technology has improved the molecular characterisation of inherited platelet disorders and has been implemented in the research studies and the clinical routine practice.

Autism spectrum disorder (ASD) is a heterogeneously pervasive developmental disorder in which various genetic and environmental factors are believed to underlie its development. Recently, epigenetics has been suggested as a novel concept for ASD aetiology with a proposition that epigenetic marks can be transgenerationally inherited. Based on this assumption of epigenetics, we investigated the transgenerational inheritance of ASD-like behaviours and their related synaptic changes in the VPA animal model of ASD. The first generation (F1) VPA-exposed offspring exhibited autistic-like impaired sociability and increased marble burying. They also showed increased seizure susceptibility, hyperactivity and decreased anxiety. We mated the VPA-exposed F1 male offspring with naïve females to produce the second generation (F2), and then similarly mated the F2 to deliver the third generation (F3). Remarkably, the autism-like behavioural phenotypes found in F1 persisted to the F2 and F3. Additionally, the frontal cortices of F1 and F3 showed some imbalanced expressions of excitatory/inhibitory synaptic markers, suggesting a transgenerational epigenetic inheritance. These results open the idea that E/I imbalance and ASD-like behavioural changes induced by environmental insults in mice can be epigenetically transmitted, at least, to the third generation. This study could help explain the unprecedented increase in ASD prevalence.

Normal maternal adaptation to pregnancy significantly increases the risk for thrombus formation. Inherited thrombophilias further increase risk for deep venous thrombosis and adverse outcome in pregnancy. Factor V Leiden mutation is the most common inherited thrombophilia, occurring in approximately 5% of the White and 1% of the Black populations. Nurses should be knowledgeable about screening for and diagnosis of factor V Leiden mutation, risk reduction counseling, recommended care of the affected patient, and implications of anticoagulant therapy during the perinatal period.

Does cross-generational epigenetic inheritance contribute to cultural continuity?

Science.gov (United States)

Pembrey, Marcus E

2018-04-01

Human studies of cross-generational epigenetic inheritance have to consider confounding by social patterning down the generations, often referred to as 'cultural inheritance'. This raises the question to what extent is 'cultural inheritance' itself epigenetically mediated rather than just learnt. Human studies of non-genetic inheritance have demonstrated that, beyond foetal life, experiences occurring in mid-childhood before puberty are the most likely to be associated with cross-generational responses in the next generation(s). It is proposed that cultural continuity is played out along the axis, or 'payoff', between responsiveness and stability. During the formative years of childhood a stable family and/or home permits small children to explore and thereby learn. To counter disruptions to this family home ideal, cultural institutions such as local schools, religious centres and market places emerged to provide ongoing stability, holding the received wisdom of the past in an accessible state. This cultural support allows the growing child to freely indulge their responsiveness. Some of these prepubertal experiences induce epigenetic responses that also transfer molecular signals to the gametes through which they contribute to the conception of future offspring. In parallel co-evolution with growing cultural support for increasing responsiveness, 'runaway' responsiveness is countered by the positive selection of genetic variants that dampen responsiveness. Testing these ideas within longitudinal multigenerational cohorts will need information on ancestors/parents' own communities and experiences (Exposome scans) linked to ongoing Phenome scans on grandchildren; coupled with epigenome analysis, metastable epialleles and DNA methylation age. Interactions with genetic variants affecting responsiveness should help inform the broad hypothesis.

The Asamblea del Año XIII in the Rio de la Plata: Eternal Laurels to End the Revolution

Directory of Open Access Journals (Sweden)

Esteban Buch

2016-09-01

Full Text Available The Asamblea del año XIII, the 1813 Constitutional Assembly in the Río de la Plata, represents at its best revolutionary velocity, with its allegro rhythm towards wider liberties and a more perfect equality, towards an independence of the nation that, without being officially declared, inspires many of its gestures, like the creation of Argentina’s national anthem. A contemporary observer fond of anachronisms might find in it a confirmation that movement is an essential element of democracy. Yet, this dynamic perception should be balanced by reminding that the Assembly’s main project is not to accelerate the revolution, but to terminate it. “Close the period of the revolution, open the epoch of peace and freedom”, says its inaugural declaration. This paper focuses on the tension between these two conceptions of historical temporality.

Co-Inheritance Analysis within the Domains of Life Substantially Improves Network Inference by Phylogenetic Profiling.

Directory of Open Access Journals (Sweden)

Junha Shin

Full Text Available Phylogenetic profiling, a network inference method based on gene inheritance profiles, has been widely used to construct functional gene networks in microbes. However, its utility for network inference in higher eukaryotes has been limited. An improved algorithm with an in-depth understanding of pathway evolution may overcome this limitation. In this study, we investigated the effects of taxonomic structures on co-inheritance analysis using 2,144 reference species in four query species: Escherichia coli, Saccharomyces cerevisiae, Arabidopsis thaliana, and Homo sapiens. We observed three clusters of reference species based on a principal component analysis of the phylogenetic profiles, which correspond to the three domains of life-Archaea, Bacteria, and Eukaryota-suggesting that pathways inherit primarily within specific domains or lower-ranked taxonomic groups during speciation. Hence, the co-inheritance pattern within a taxonomic group may be eroded by confounding inheritance patterns from irrelevant taxonomic groups. We demonstrated that co-inheritance analysis within domains substantially improved network inference not only in microbe species but also in the higher eukaryotes, including humans. Although we observed two sub-domain clusters of reference species within Eukaryota, co-inheritance analysis within these sub-domain taxonomic groups only marginally improved network inference. Therefore, we conclude that co-inheritance analysis within domains is the optimal approach to network inference with the given reference species. The construction of a series of human gene networks with increasing sample sizes of the reference species for each domain revealed that the size of the high-accuracy networks increased as additional reference species genomes were included, suggesting that within-domain co-inheritance analysis will continue to expand human gene networks as genomes of additional species are sequenced. Taken together, we propose that co-inheritance

Sadovskij, V.D.; Bershtejn, L.I.; Mel'nikova, A.A.; Polyakova, A.M.; Schastlivtsev, V.M.

1980-01-01

Structural inheritance in the cast 30KhGNM-type steel depending on the heating rate and the temperature of preliminary tempering is investigated. When eating the cast steel with a beinite structure at the rate of 1-150 deg/min, the restoration of austenite grain and the following recrystallization due to the phase cold work, are observed. Slow heating from room temperature or preliminary tempering hinder grain restoration during heating. A non-monotonous effect of tempering temperature on the structural inheritance is established which can be connected with the kinetics of decomposition of residual austenite in steel

Effect of structural inheritance on effectiveness of 'intercritical quenching'

International Nuclear Information System (INIS)

Kut'in, A.B.; Polyakova, A.M.; Gerbikh, N.M.

1989-01-01

Effect of quenching from intercritical interval on tempering brittleness suppression by comparing structural changes under heating of steels which do not tend to structural inheritance and steels, additionally doped with elements increasing the tendency of preliminary quenching grain to reduction, is studied. Investigation was conducted using medium-carbon chromium nickel steels, melted in an open induction furnace. It is shown that effect of quenching from intercritical interval on the tempering brittleness attennuation is increased with the increase of steel tendency to structural inheritance. Intergranular embrittlement suppression at tempering is obviously caused by a uniform distribution of impurities on subboundaries in the grain volume

Assessment of Inheritance and Fitness Costs Associated with Field-Evolved Resistance to Cry3Bb1 Maize by Western Corn Rootworm.

Science.gov (United States)

Paolino, Aubrey R; Gassmann, Aaron J

2017-05-11

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious insect pests of maize in North America. One strategy used to manage this pest is transgenic maize that produces one or more crystalline (Cry) toxins derived from the bacterium Bacillus thuringiensis (Bt). To delay Bt resistance by insect pests, refuges of non-Bt maize are grown in conjunction with Bt maize. Two factors influencing the success of the refuge strategy to delay resistance are the inheritance of resistance and fitness costs, with greater delays in resistance expected when inheritance of resistance is recessive and fitness costs are present. We measured inheritance and fitness costs of resistance for two strains of western corn rootworm with field-evolved resistance to Cry3Bb1 maize. Plant-based and diet-based bioassays revealed that the inheritance of resistance was non-recessive. In a greenhouse experiment, in which larvae were reared on whole maize plants in field soil, no fitness costs of resistance were detected. In a laboratory experiment, in which larvae experienced intraspecific and interspecific competition for food, a fitness cost of delayed larval development was identified, however, no other fitness costs were found. These findings of non-recessive inheritance of resistance and minimal fitness costs, highlight the potential for the rapid evolution of resistance to Cry3Bb1 maize by western corn rootworm, and may help to improve resistance management strategies for this pest.

The human growth hormone-releasing factor (GRF) peptides (GlyS/sup 15/)-GRF-(1-15) (IV), trifluoroacetyl-GRF-(20-44) (VI), trifluoroacetyl-GRF-(18-44) (VIII), and trifluoroacetyl-GRF-(16-44) (X) were synthesized by the solidphase method. Each of the peptides was reacted with citraconic anhydride and the trifluoroacetyl group was removed by reaction with 10% hydrazine in water. The citraconylated GRF-(1-15) peptide was coupled to the (20-44), (18-44) or (16-44) peptides by reaction with silver nitrate/N-hydroxysuccinimide to give GRF-(1-15)-(20-44) (XII), GRF-(1-15)-(18-44) (XIII), or GRF-(1-44), respectively. GRF-(1-44) was shown to stimulate the release of rat growth hormone from rat pituitary cells with an ED/sub 50/=8.8 x 10/sup -11/M. Peptides XII and XIII were inactive, either as agonists or as antagonists of the action of GRF-(1-44).

Inheritance of proportionate dwarfism in Angus cattle.

Science.gov (United States)

Latter, M R; Latter, B D H; Wilkins, J F; Windsor, P A

2006-04-01

To determine the mode of inheritance of congenital proportionate dwarfism in Angus and Angus crossbred cattle, initially detected in two commercial beef herds in northern New South Wales. Matings of normal carrier sires to unrelated cows of diverse breeds, and of one carrier sire to his unaffected daughters. An unrelated Piedmontese bull was also mated to unaffected daughters of the carrier sires. Two carrier Angus bulls and nine unaffected daughters, all of whom were completely indistinguishable from normal animals, were purchased for controlled breeding studies under known nutritional and disease conditions. Affected and carrier individuals were examined for the presence of obvious chromosomal abnormalities. Angus dwarfism has been successfully reproduced under controlled experimental conditions over successive years using unrelated dams and is undoubtedly heritable. The high frequency of occurrence of affected individuals (23/61 = 0.38 +/- .06) among the progeny of matings of the Angus sires to unrelated females of diverse breeding is not compatible with recessive inheritance, because of the negligible frequency of proportionate dwarfism in the breeds of the dams. Both paternal and maternal transmission of the defect was demonstrated, so that imprinting in the strict sense of a gene that is only expressed when received from the male parent appears not to be involved. Tested individuals showed no evidence of gross chromosomal abnormality. Dominant autosomal inheritance with incomplete penetrance was indicated by the lack of expression of the defective gene in the two Angus sires and in three unaffected daughters who produced dwarf calves from matings to the Piedmontese bull. The mode of inheritance is that of a single autosomal dominant gene with a penetrance coefficient of 0.75 +/- 0.12, estimated from the observed incidence of 23/61 affected offspring of the two carrier Angus bulls mated to unrelated dams.

2012-01-01

Full Text Available Inheritance of glyphosate resistance in a Palmer amaranth biotype from North Carolina was studied. Glyphosate rates for 50% survival of glyphosate-resistant (GR and glyphosate-susceptible (GS biotypes were 1288 and 58 g ha−1, respectively. These values for F1 progenies obtained from reciprocal crosses (GR×GS and GS×GR were 794 and 501 g ha−1, respectively. Dose response of F1 progenies indicated that resistance was not fully dominant over susceptibility. Lack of significant differences between dose responses for reciprocal F1 families suggested that genetic control of glyphosate resistance was governed by nuclear genome. Analysis of F1 backcross (BC1F1 families showed that 10 and 8 BC1F1 families out of 15 fitted monogenic inheritance at 2000 and 3000 g ha−1 glyphosate, respectively. These results indicate that inheritance of glyphosate resistance in this biotype is incompletely dominant, nuclear inherited, and might not be consistent with a single gene mechanism of inheritance. Relative 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS copy number varied from 22 to 63 across 10 individuals from resistant biotype. This suggested that variable EPSPS copy number in the parents might be influential in determining if inheritance of glyphosate resistance is monogenic or polygenic in this biotype.

A Unification of Inheritance and Automatic Program Specialization

DEFF Research Database (Denmark)

Schultz, Ulrik Pagh

2004-01-01

, inheritance is used to control the automatic application of program specialization to class members during compilation to obtain an efficient implementation. This paper presents the language JUST, which integrates object-oriented concepts, block structure, and techniques from automatic program specialization......The object-oriented style of programming facilitates program adaptation and enhances program genericness, but at the expense of efficiency. Automatic program specialization can be used to generate specialized, efficient implementations for specific scenarios, but requires the program...... to be structured appropriately for specialization and is yet another new concept for the programmer to understand and apply. We have unified automatic program specialization and inheritance into a single concept, and implemented this approach in a modified version of Java named JUST. When programming in JUST...

Gender Sensitivity and the Inheritance Act of The Bahamas, 1833

Directory of Open Access Journals (Sweden)

Sabrina A. Russell-Skinner

2008-02-01

Full Text Available The motivation for this paper stemmed from the realization that discrimination against women in the Bahamas still exists, is being continually perpetuated and, in fact, is institutionalized by the law which should enforce justice for all. Against the backdrop of preparation for the 1995 United Nations Conference on Women, a closer look is taken at gender discrimination in the Bahamas by examining the Constitution and the Inheritance Act of 1833. The assumption that institutionalized patriarchy gives rise to gender discrimination guides the analysis. The organs of male domination and the reasons for its perpetuation are discussed as well as obstacles to the passage of the draft Inheritance Bill (1983. It is recommended the inequities arising from an inbuilt structure of a male dominated society be addressed by legislation that will ensure equity and social justice for all. Finally, it is suggested that the draft Inheritance Bill (1983 with modifications to some provisions has the potential to accomplish this.

Inherited variants in regulatory T cell genes and outcome of ovarian cancer.

Full Text Available Although ovarian cancer is the most lethal of gynecologic malignancies, wide variation in outcome following conventional therapy continues to exist. The presence of tumor-infiltrating regulatory T cells (Tregs has a role in outcome of this disease, and a growing body of data supports the existence of inherited prognostic factors. However, the role of inherited variants in genes encoding Treg-related immune molecules has not been fully explored. We analyzed expression quantitative trait loci (eQTL and sequence-based tagging single nucleotide polymorphisms (tagSNPs for 54 genes associated with Tregs in 3,662 invasive ovarian cancer cases. With adjustment for known prognostic factors, suggestive results were observed among rarer histological subtypes; poorer survival was associated with minor alleles at SNPs in RGS1 (clear cell, rs10921202, p=2.7×10(-5, LRRC32 and TNFRSF18/TNFRSF4 (mucinous, rs3781699, p=4.5×10(-4, and rs3753348, p=9.0×10(-4, respectively, and CD80 (endometrioid, rs13071247, p=8.0×10(-4. Fo0r the latter, correlative data support a CD80 rs13071247 genotype association with CD80 tumor RNA expression (p=0.006. An additional eQTL SNP in CD80 was associated with shorter survival (rs7804190, p=8.1×10(-4 among all cases combined. As the products of these genes are known to affect induction, trafficking, or immunosuppressive function of Tregs, these results suggest the need for follow-up phenotypic studies.

Full Text Available The coagulation system provides a primitive but effective defense against hemorrhage. Soluble fibrinogen (Fg monomers, composed of α, β and γ chains, are recruited to provide structural support for the formation of a hemostatic plug. Fg binds to platelets and is processed into a cross-linked fibrin polymer by the enzymatic clotting factors, thrombin and Factor XIII (FXIII. The newly formed fibrin-platelet clot can act as barrier to protect against pathogens from entering the bloodstream. Further, injuries caused by bacterial infections can be confined to the initial wound site. Many pathogenic bacteria have Fg-binding adhesins that can circumvent the coagulation pathway and allow the bacteria to sidestep containment. Fg expression is upregulated during lung infection providing an attachment surface for bacteria with the ability to produce Fg-binding adhesins. Fg binding by leptospira might play a crucial factor in Leptospira-associated pulmonary hemorrhage, the main factor contributing to lethality in severe cases of leptospirosis. The 12th domain of Leptospira immunoglobulin-like protein B (LigB12, a leptospiral adhesin, interacts with the C-terminus of FgαC (FgαCC.

The association of FgαCC8 with LigB12 (ELISA, KD = 0.76 μM; SPR, KD = 0.96 μM was reduced by mutations of both charged residues (R608, R611 and H614 from FgαCC8; D1061 from LigB12 and hydrophobic residues (I613 from FgαCC8; F1054 and A1065 from LigB12. Additionally, LigB12 bound strongly to FXIII and also inhibited fibrin formation, suggesting that LigB can disrupt coagulation by suppressing FXIII activity. Here, the detailed binding mechanism of a leptospiral adhesin to a host hemostatic factor is characterized for the first time and should provide better insight into the pathogenesis of leptospirosis.

Full Text Available Abstract Background Proper management of patients with Kallmann syndrome (KS allows them to attain a normal reproductive health. The purpose of this study is to demonstrate the presentation modalities, phenotypes and the modes of inheritance among 32 patients with Kallmann syndrome in Jordan. Recognition of the syndrome allows for prompt proper management and provision of genetic counselling. Subjects Over a period of five years (1999–2004, the clinical and inheritance profiles of 26 male and 6 female patients with Kallmann syndrome from 12 families were evaluated at the National Center for Diabetes, Endocrinology and Genetics in Jordan. Results The patients belonged to twelve Jordanian and Palestinian families and their age at presentation ranged from 4 – 46 years. Nine boys aged 4–14 years presented with cryptorchidism and microphallus, all other males presented with delayed puberty, hypogonadism and/or infertility. The main presentation among six female patients was primary amenorrhea. Intrafamilial variability in clinical phenotype was specifically evident for renal abnormalities and sensorineural hearing impairment. Familial KS was diagnosed in 27 patients belonging to five families with the X-linked mode of inheritance and two families with the autosomal recessive mode of inheritance. Conclusions (1 the majority of cases in this study represented the X-linked form of KS, which might point to a high prevalence of Kal 1 gene in the population. (2 Genetic counselling helps these families to reach a diagnosis at an early age and to decide about their reproductive options. (3 Children presenting with cryptorchidism and microphallus in our population should be investigated for KS.

DNA mutation motifs in the genes associated with inherited diseases.

Directory of Open Access Journals (Sweden)

Michal Růžička

Full Text Available Mutations in human genes can be responsible for inherited genetic disorders and cancer. Mutations can arise due to environmental factors or spontaneously. It has been shown that certain DNA sequences are more prone to mutate. These sites are termed hotspots and exhibit a higher mutation frequency than expected by chance. In contrast, DNA sequences with lower mutation frequencies than expected by chance are termed coldspots. Mutation hotspots are usually derived from a mutation spectrum, which reflects particular population where an effect of a common ancestor plays a role. To detect coldspots/hotspots unaffected by population bias, we analysed the presence of germline mutations obtained from HGMD database in the 5-nucleotide segments repeatedly occurring in genes associated with common inherited disorders, in particular, the PAH, LDLR, CFTR, F8, and F9 genes. Statistically significant sequences (mutational motifs rarely associated with mutations (coldspots and frequently associated with mutations (hotspots exhibited characteristic sequence patterns, e.g. coldspots contained purine tract while hotspots showed alternating purine-pyrimidine bases, often with the presence of CpG dinucleotide. Using molecular dynamics simulations and free energy calculations, we analysed the global bending properties of two selected coldspots and two hotspots with a G/T mismatch. We observed that the coldspots were inherently more flexible than the hotspots. We assume that this property might be critical for effective mismatch repair as DNA with a mutation recognized by MutSα protein is noticeably bent.

To describe the simultaneous occurence of an autosomal dominant inherited MSX1 mutation and an X-linked recessive inherited EDA mutation in one Chinese family with nonsyndromic oligodontia. Clinical data of characteristics of tooth agenesis were collected. MSX1 and EDA gene mutations were detected in a Chinese family of non-syndromic oligodontia. Mild hypodontia in the parents and severe oligodontia in the son was recorded. A novel missense heterozygous mutation c.517C>A (p.Arg173Ser) was detected in the MSX1 gene in the boy and the father. A homozygous missense mutation c.1001G>A (p.Arg334His) was detected in the EDA gene in the boy and the same mutant occurred heterozygously in the mother. Simultaneous occurence of two different gene mutations with different inheritence patterns, which both caused oligodontia, which occurred in one subject and in one family, was reported.

A retrospective study of the inheritance of peromelia in Angora goats

in Angora goats, breeding results for goats being daughters of known carriers and which were then mated to a known carrier were analysed. Of 45 kids born in 1993 and 1994, five kids had peromelia. This corresponded to the expected 7:1 segregation. The difference between the number of affected male...... and female kids was not statistically significant. Peromelia affected kids occurred significantly more frequently among goats selected in the breeding study than among other goats in the respective herds. The study demonstrated that peromelia is inherited as an autosomal recessive defect. Based on knowledge......Peromelia, agenesia of the distal parts of the limbs, has been reported as a congenital defect in several animal species. In Angora goats, cases occur in a familiar pattern consistent with an autosomal recessively inherited defect. To obtain further evidence on the inheritance of peromelia...

This article investigates the relationship between inheritance and wealth in the context of eighteenth-century Ottoman Kastamonu. Based on the estate inventories of the deceased (sing. tereke) as recorded in Kastamonu court records (sicils), the article introduces a variety of quantitative techniques to measure the impact of Islamic inheritance practices on wealth accumulation across subsequent generations and to understand how it influenced wealth mobility among various socioeconomic groups. The estimations provided in this article suggest that while the inheritance practice in Kastamonu caused wealth fragmentation, the process also contributed to the durability of economic divisions within the provincial Ottoman society.

The daughter who gave up her inheritance: Ethnography of women’s inheritance rights and their application in contemporary Macedonian context

Ana Ashtalkovska Gajtanoska

2017-08-01

Full Text Available This text examines the experiences of several women ethnologists / anthropologists in regard to women’s inheritance rights and the traditional practices used in contemporary context in Macedonia. Women’s inheritance rights and traditional norms, which, according to the ideal model, recommend that a woman cannot be an heir of immovable property, are among the main associations of patriarchy on the Balkans. The women interlocutors in this research consistently hold on to the thesis that the term “patriarchy” is inadequate for describing in general terms the status of women in the radically divided periods of the traditional past or the contemporary context. Therefore, this situation entails a great methodological challenge in the context of the research theme, when the experiences from the everyday life of the researchers seem to contradict their theses in regard to patriarchy.

A thirty million year-old inherited heteroplasmy.

Directory of Open Access Journals (Sweden)

Vincent Doublet

Full Text Available Due to essentially maternal inheritance and a bottleneck effect during early oogenesis, newly arising mitochondrial DNA (mtDNA mutations segregate rapidly in metazoan female germlines. Consequently, heteroplasmy (i.e. the mixture of mtDNA genotypes within an organism is generally resolved to homoplasmy within a few generations. Here, we report an exceptional transpecific heteroplasmy (predicting an alanine/valine alloacceptor tRNA change that has been stably inherited in oniscid crustaceans for at least thirty million years. Our results suggest that this heteroplasmy is stably transmitted across generations because it occurs within mitochondria and therefore escapes the mtDNA bottleneck that usually erases heteroplasmy. Consistently, at least two oniscid species possess an atypical trimeric mitochondrial genome, which provides an adequate substrate for the emergence of a constitutive intra-mitochondrial heteroplasmy. Persistence of a mitochondrial polymorphism on such a deep evolutionary timescale suggests that balancing selection may be shaping mitochondrial sequence evolution in oniscid crustaceans.

Full Text Available A research to get inheritance of Arabica coffee resistance to Radopholus similisnematode was done in screen house and laboratory of Indonesian Coffee and Cocoa Research Institute, also at endemic area of coffee plantation, using F1, F1 R and F2 crossing between BP 542 A(resistant x Andungsari 1 (susceptible with their reciprocal, and BP 542 A x Kartika 1. The purpose of this study that was conducted at seedling stage is to formulate a Strategy for Arabica coffee breeding to get resistant varieties to nematode. As the variables of resistance were weight of seedling biomass, percent of root weight deviation, number of root nematodes, number of soil nematodes, reproduction and percent of necrotic root. Using discriminant analysis and fastclus, those data variables were analyzed for genetic of resistance with Statistical Analysis System programme version 8. Genetic study on the inheritance of resistance to R. similiswas started with evaluation of homozigosity of BP 542 A was resistant parent. The result showed that BP 542 A was heterozygous. Therefore, segregation test could not be suggested with segregation pattern principals as Mendel proposed. Segregation test on BP 542 A showed that it was heterozygote and the resistance was controlled by single gene with complete dominant effect, so the progeny segregated in 75% resistant and 25% susceptible. The result of the test showed the absence of maternal effect for root weight deviation and percentage of necrotic root variables, which meant that no cytoplasmic inheritance was involved. Based on the test of segregation ratio, almost all of the resistance was not appropriate for monogenic and or digenic segregation pattern as expected due to non allelic gene interaction that caused epistasis. Key words: Inheritance, resistance, Arabica coffee, Radopholus similis.

Role of structural inheritance on present-day deformation in intraplate domains

Science.gov (United States)

Tarayoun, A.; Mazzotti, S.; Gueydan, F.

2017-12-01

Understanding the role of structural inheritance on present day surface deformation is a key element for better characterizing the dynamism of intraplate earthquakes. Current deformation and seismicity are poorly understood phenomenon in intra-continental domains. A commonly used hypothesis, based on observations, suggests that intraplate deformation is related to the reactivation of large tectonic paleo-structures, which can act as locally weakened domains. The objective of our study is to quantify the impact of these weakened areas on present-day strain localizations and rates. We combine GPS observations and numerical modeling to analyze the role of structural inheritance on strain rates, with specific observations along the St. Lawrence Valley of eastern Canada. We processed 143 GPS stations from five different networks, in particular one dense campaign network situated along a recognized major normal faults system of the Iapetus paleo-rift, in order to accurately determine the GPS velocities and strain rates. Results of strain rates show magnitude varying from 1.5x10-10 to 6.8x10-9 yr-1 in the St Lawrence valley. Weakened area strain rates are up to one order of magnitude higher than surrounding areas. We compare strain rates inferred from GPS and the new postglacial rebound model. We found that GPS signal is one order of magnitude higher in the weakened zone, which is likely due to structural inheritance. The numerical modeling investigates the steady-state deformation of the continental lithosphere with presence of a weak area. Our new approach integrates ductile structural inheritance using a weakening coefficient that decreases the lithosphere strength at different depths. This allows studying crustal strain rates mainly as a function of rheological contrast and geometry of the weakened domains. Comparison between model predictions and observed GPS strain rates will allow us to investigate the respective role of crustal and mantle tectonic inheritance.

GENDER ASPECTS OF INHERITANCE MANAGEMENT IN GEORGIA CULTURAL PRACTICES VS LAW REGULATIONS

Directory of Open Access Journals (Sweden)

Maia Araviashvili

2014-12-01

Full Text Available After gaining independence in 1991 Georgia adopted the new constitution, received liberal laws and joined international conventions, which formally guarantee gender equality. However, law regulations do not come in accordance with cultural values, and are not shared by society. Consequently, the problems of gender inequality are still vital issues in Georgian society. Traditionally, informal practice of dowry giving protected women and gave them independence in a new family. Nowadays, in Georgia a daughter and a son formally have equal access to their parent’s inheritance, but there are very rare cases when a woman demands her part of it. This is not justified by society to contend for the inheritance with a brother. Formal institutions are not strong to prevent this economic form of domestic violence. The methodology of the research is complex: expert interviews were recorded and analyzed, to study data about the inheritance registration and court records pertaining to inheritance litigations, the method of content analysis was used; apart from this, ethnographic resources and surveys were examined. The findings of the proposed research article provide a complex picture of this really vital problem still affecting the post-soviet Georgian society.

Multiple ways to prevent transmission of paternal mitochondrial DNA for maternal inheritance in animals.

Science.gov (United States)

Sato, Ken; Sato, Miyuki

2017-10-01

Mitochondria contain their own DNA (mtDNA). In most sexually reproducing organisms, mtDNA is inherited maternally (uniparentally); this type of inheritance is thus referred to as 'maternal (uniparental) inheritance'. Recent studies have revealed various mechanisms to prevent the transmission of sperm-derived paternal mtDNA to the offspring, thereby ensuring maternal inheritance of mtDNA. In the nematode Caenorhabditis elegans, paternal mitochondria and their mtDNA degenerate almost immediately after fertilization and are selectively degraded by autophagy, which is referred to as 'allophagy' (allogeneic [non-self] organelle autophagy). In the fruit fly Drosophila melanogaster, paternal mtDNA is largely eliminated by an endonuclease G-mediated mechanism. Paternal mitochondria are subsequently removed by endocytic and autophagic pathways after fertilization. In many mammals, including humans, paternal mitochondria enter fertilized eggs. However, the fate of paternal mitochondria and their mtDNA in mammals is still a matter of debate. In this review, we will summarize recent knowledge on the molecular mechanisms underlying the prevention of paternal mtDNA transmission, which ensures maternal mtDNA inheritance in animals. © The Authors 2017.

The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

High-throughput Screening for Protein-based Inheritance in S. cerevisiae.

Science.gov (United States)

Byers, James S; Jarosz, Daniel F

2017-08-08

The encoding of biological information that is accessible to future generations is generally achieved via changes to the DNA sequence. Long-lived inheritance encoded in protein conformation (rather than sequence) has long been viewed as paradigm-shifting but rare. The best characterized examples of such epigenetic elements are prions, which possess a self-assembling behavior that can drive the heritable manifestation of new phenotypes. Many archetypal prions display a striking N/Q-rich sequence bias and assemble into an amyloid fold. These unusual features have informed most screening efforts to identify new prion proteins. However, at least three known prions (including the founding prion, PrP Sc ) do not harbor these biochemical characteristics. We therefore developed an alternative method to probe the scope of protein-based inheritance based on a property of mass action: the transient overexpression of prion proteins increases the frequency at which they acquire a self-templating conformation. This paper describes a method for analyzing the capacity of the yeast ORFeome to elicit protein-based inheritance. Using this strategy, we previously found that >1% of yeast proteins could fuel the emergence of biological traits that were long-lived, stable, and arose more frequently than genetic mutation. This approach can be employed in high throughput across entire ORFeomes or as a targeted screening paradigm for specific genetic networks or environmental stimuli. Just as forward genetic screens define numerous developmental and signaling pathways, these techniques provide a methodology to investigate the influence of protein-based inheritance in biological processes.

The diamondback moth, Plutella xylostella (L.) has developed resistance to many types of insecticides in the field. To study inheritance and fitness cost of metaflumizone resistance, a susceptible strain of diamondback moth was continuously selected with metaflumizone during 37 generations under laboratory conditions. The resistance to metaflumizone was at a high level (resistance ratios from 250.37 to 1450.47-fold). We investigated a metaflumizone resistance strain (G 27 ) and a susceptible strain of P. xylostella, using the age-stage, two-sex life table approach. Compared to the susceptible strain, egg duration, the developmental time of the first and second instar larvae, pupae duration, adult preoviposition period (APOP), total preoviposition period (TPOP), egg hatchability, the survival rate of second instar larva and the mean generation time (T) were significantly differences in the resistant strain. The resistant strain had a relative fitness of 0.78. The inheritance of metaflumizone resistance was also studied by crossing the metaflumizone resistant and susceptible populations. Results revealed an autosomal and incompletely recessive mode of inheritance for metaflumizone resistance in the resistant population of P. xylostella. The present study provided useful information for planning potential management strategies to delay development of metaflumizone resistance in P. xylostella. Copyright © 2017 Elsevier Inc.

Global Carrier Rates of Rare Inherited Disorders Using Population Exome Sequences.

Directory of Open Access Journals (Sweden)

Kohei Fujikura

Full Text Available Exome sequencing has revealed the causative mutations behind numerous rare, inherited disorders, but it is challenging to find reliable epidemiological values for rare disorders. Here, I provide a genetic epidemiology method to identify the causative mutations behind rare, inherited disorders using two population exome sequences (1000 Genomes and NHLBI. I created global maps of carrier rate distribution for 18 recessive disorders in 16 diverse ethnic populations. Out of a total of 161 mutations associated with 18 recessive disorders, I detected 24 mutations in either or both exome studies. The genetic mapping revealed strong international spatial heterogeneities in the carrier patterns of the inherited disorders. I next validated this methodology by statistically evaluating the carrier rate of one well-understood disorder, sickle cell anemia (SCA. The population exome-based epidemiology of SCA [African (allele frequency (AF = 0.0454, N = 2447, Asian (AF = 0, N = 286, European (AF = 0.000214, N = 4677, and Hispanic (AF = 0.0111, N = 362] was not significantly different from that obtained from a clinical prevalence survey. A pair-wise proportion test revealed no significant differences between the two exome projects in terms of AF (46/48 cases; P > 0.05. I conclude that population exome-based carrier rates can form the foundation for a prospectively maintained database of use to clinical geneticists. Similar modeling methods can be applied to many inherited disorders.

Experimental Models of Inherited PrP Prion Diseases.

The inherited prion protein (PrP) prion disorders, which include familial Creutzfeldt-Jakob disease, Gerstmann-Sträussler-Scheinker disease, and fatal familial insomnia, constitute ∼10%-15% of all PrP prion disease cases in humans. Attempts to generate animal models of these disorders using transgenic mice expressing mutant PrP have produced variable results. Although many lines of mice develop spontaneous signs of neurological illness with accompanying prion disease-specific neuropathological changes, others do not. Furthermore, demonstrating the presence of protease-resistant PrP species and prion infectivity-two of the hallmarks of the PrP prion disorders-in the brains of spontaneously sick mice has proven particularly challenging. Here, we review the progress that has been made toward developing accurate mouse models of the inherited PrP prion disorders.

Zonana, J; Sotos, J F; Romshe, C A; Fisher, D A; Elders, M J; Rimoin, D L

1977-08-01

Cerebral gigantism is a syndrome consisting of characteristic dysmorphic features, accelerated growth in early childhood, and variable degrees of mental retardation. Its etiology and pathogenesis have not been defined. Three families are presented with multiple affected members. The vertical transmission of the trait and equal expression in both sexes in these families indicates a genetic etiology with a dominant pattern of inheritance, probably autosomal. As in previously reported cases, extensive endocrine evaluation failed to define the pathogenesis of the accelerated growth present in this disorder.

Inherited chromosomally integrated human herpesvirus-6 (iciHHV-6) results in the germ-line transmission of the HHV-6 genome. Every somatic cell of iciHHV-6+ individuals contains the HHV-6 genome integrated in the telomere of chromosomes. Whether having iciHHV-6 predisposes humans to diseases remains undefined. DNA from 19,597 participants between 40 and 69 years of age were analyzed by quantitative PCR (qPCR) for the presence of iciHHV-6. Telomere lengths were determined by qPCR. Medical records, hematological, biochemical, and anthropometric measurements and telomere lengths were compared between iciHHV-6+ and iciHHV-6- subjects. The prevalence of iciHHV-6 was 0.58%. Two-way ANOVA with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on continuous outcomes. Two-way logistic regression with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on disease prevalence. Of 50 diseases monitored, a single one, angina pectoris, is significantly elevated (3.3×) in iciHHV-6+ individuals relative to iciHHV-6- subjects (P = 0.017; 95% CI, 1.73-6.35). When adjusted for potential confounding factors (age, body mass index, percent body fat, and systolic blood pressure), the prevalence of angina remained three times greater in iciHHV-6+ subjects (P = 0.015; 95%CI, 1.23-7.15). Analyses of telomere lengths between iciHHV-6- without angina, iciHHV-6- with angina, and iciHHV-6+ with angina indicate that iciHHV-6+ with angina have shorter telomeres than age-matched iciHHV-6- subjects (P = 0.006). Our study represents, to our knowledge, the first large-scale analysis of disease association with iciHHV-6. Our results are consistent with iciHHV-6 representing a risk factor for the development of angina.

This study determined the midterm outcome of valve-sparing aortic root replacement for patients with inherited connective tissue disorders. From 1993 to 2008, 94 patients underwent valve-sparing aortic root replacement. Sixty patients (64%), average age 33 years (range, 15 to 61 years), had inherited connective tissue disorders: Marfan syndrome, 54 (92%); Loeys-Dietz syndrome, 5 (8%); and smooth muscle α-actin (ACTA2) mutation in 1. Median preoperative sinus diameter was 52 mm (range, 42 to 76 mm), and moderate/severe aortic regurgitation was present in 14 (23%). Seven (12%, 1993 to 1999) underwent remodeling procedures, and 53 had reimplantation procedures. Cusp repair was performed in 4. Median follow-up was 55 months (range, 1 to 149 months). There were 15 patients in the early term (1993 to 2000) and 45 in the late term (2001 to 2008). Four late deaths occurred (cardiac, 3; aortic, 1), with 10-year survival of 86%. Rates of freedom from aortic valve replacement at 5 and 10 years were 85% and 58% in remodeling and 96% and 58% in reimplantation. Risk factors for reoperations were postprocedure intraoperative aortic insufficiency greater than mild (p = 0.046), remodeling procedure (p = 0.016), and early term (p = 0.0002). One patient (2%) with none/trivial postprocedure aortic insufficiency required aortic valve replacement. Freedom from reoperation in patients with none/trivial postprocedure aortic insufficiency at 5 and 10 years was 100% and 67%. Meticulous control of aortic insufficiency during operation would bring favorable midterm durability in valve-sparing aortic root replacement using a reimplantation technique, even in patients with inherited connective tissue disorders.

Inheritance of fruit colour in normal and irradiated progenies of brinjal

International Nuclear Information System (INIS)

Gopimony, R.; George, M.K.; Gopinathan Nair, V.

1980-01-01

The inheritance of fruit colour in brinjal (Solanum melongena) was studied by analysing the progeny belonging to the F 1 M 2 , F 1 M 1 and F 2 M 2 generations resulting from a cross between varieties insanum and purple giant followed by gamma irradiation. The F 2 phenotypic frequencies fitted very well with the dihybrid ratio indicating that the fruit colour is governed by two independently inherited genes. Three colour mutants, namely, purple, mottled green and white were induced in the F 1 M 1 generation by the irradiation. The appearance of these mutants is explained as due to independent mutations at either or both of the two goenetic loci. The colour pattern in the F 2 M 2 progenies derived from the F 1 M 1 mutants substantiates the two gene mechanism for the inheritance of fruit colour. The genotypes for the different colour types in the F 1 , F 2 and F 1 M 1 mutants have been indicated and discussed. (author)

Inclined inheritance of interface roughness in semiconductor superlattices as characterized by x-ray reciprocal space mapping

International Nuclear Information System (INIS)

Schmidbauer, M.; Opitz, R.; Wiebach, Th.; Koehler, R.

2001-01-01

The inclined inheritance of interface roughness is investigated for an AlASGaAs superlattice grown by molecular beam epitaxy on a vicinal (001) GaAs substrate. As a consequence of vertical correlation of the roughness of subsequent interfaces the diffusely scattered x-ray intensity is bunched into resonant diffuse scattering (RDS) sheets in reciprocal space. Inclined inheritance leads to corresponding shearing of the RDS sheets. A simple model for the evaluation of inclined roughness inheritance in three dimensions is presented, where the sheared RDS sheets are modeled by anisotropic sheared ellipsoids. From measurements at different azimuthal sample orientations the two angles characterizing the inclined inheritance of interface roughness can be determined accurately. At the present sample the inheritance of interface roughness approximately follows the direction of step flow during growth. The results show that a three-dimensional analysis of diffuse scattering is necessary for a correct evaluation and interpretation

Memon, Naureen; Weinberger, Barry I; Hegyi, Thomas; Aleksunes, Lauren M

2016-01-01

Inherited disorders of hyperbilirubinemia may be caused by increased bilirubin production or decreased bilirubin clearance. Reduced hepatic bilirubin clearance can be due to defective 1) unconjugated bilirubin uptake and intrahepatic storage, 2) conjugation of glucuronic acid to bilirubin (e.g. Gilbert syndrome, Crigler-Najjar syndrome, Lucey-Driscoll syndrome, breast milk jaundice), 3) bilirubin excretion into bile (Dubin-Johnson syndrome), or 4) conjugated bilirubin re-uptake (Rotor syndrome). In this review, the molecular mechanisms and clinical manifestations of these conditions are described, as well as current approaches to diagnosis and therapy. PMID:26595536

Navarro Palazón, Julio

2011-12-01

Full Text Available The evolution of the materials and building techniques of the andalusian city of Murcia between the 9th and 13th centuries are here studied, mainly based on the new information provided by the numerous archaeological excavations that have been carried out in the city for the last thirty years, related especially to residential architecture. After its accuracy analysis, some differences between the buildings techniques manufactured in the 10th and 11th centuries and those later attributed to 12th and 13th centuries have been identified, being thus highly important to describe them by remarking at the same time those distinguishing features. Problems related to the absolute chronology of these building techniques are also discussed, highlighting the definitive information currently known. With the main aim of analysing how general these remarks are or, on the contrary, if they depend on the regionalization phenomenon characterizing the andalusian recording material, we will compare the information obtained in Murcia with those coming from other andalusian sites, located these far away from the studied area. Finally, we will check if there are differences between the rural and urban environments by comparing the materials and building techniques recorded in two coetaneous sites in Murcia, both sited close to the same river Segura and 40 km distant from each other: the city of Murcia (a large madîna and the deserted settlement of Siyâsa (a hisn.En el presente trabajo estudiamos la evolución de los materiales y técnicas constructivas en la Murcia andalusí, durante un periodo de tiempo que se extiende entre los siglos X y XIII, para lo que nos basaremos especialmente en la rica información extraída de las numerosas excavaciones efectuadas en dicha ciudad, que se refiere sobre todo a arquitectura residencial.

Eleonora Tola

2010-12-01

Full Text Available In book XIII of his Metamorphoses Ovid presents the contest for the arms of Achilles between Ajax and Ulysses. The speeches that they address to the assembly of Greek show a judicial process according to the norms of Roman rhetoric. Through his traditional facundia Ulysses persuades his public and gains victory after a confrontation that relates to a verbal fight. I will explore the construction of Ulysses’s discursive superiority focusing especially on two key-places of his speech, exordium (128-139 and peroratio (339-381. I will identify different syntactic, metrical and stylistic strategies with which Ulysses captivates his interlocutors. From a metapoetic perspective, Ovid’s tale establishes some resonances between the character’s Fama and its own textual mechanisms.

Paternal inheritance of classic X-linked bilateral periventricular nodular heterotopia.

Periventricular nodular heterotopia (PNH) is a developmental disorder of the central nervous system, characterized by heterotopic nodules of gray matter resulting from disturbed neuronal migration. The most common form of bilateral PNH is X-linked dominant inherited, caused by mutations in the Filamin A gene (FLNA) and associated with a wide variety of other clinical findings including congenital heart disease. The typical patient with FLNA-associated PNH is female and presents with difficult to treat seizures. In contrast, hemizygous FLNA loss of function mutations in males are reported to be perinatally lethal. In X-linked dominant traits like FLNA-associated PNH the causal mutation is commonly inherited from the mother. Here, we present an exceptional family with paternal transmission of classic bilateral FLNA-associated PNH from a mildly affected father with somatic and germline mosaicism for a c.5686G>A FLNA splice mutation to both daughters with strikingly variable clinical manifestation and PNH extent in cerebral MR imaging. Our observations emphasize the importance to consider in genetic counseling and risk assessment the rare genetic constellation of paternal transmission for families with X-linked dominant inherited FLNA-associated PNH.

Radio-induced inherited sterility in Heliothis zea (Boddie)

International Nuclear Information System (INIS)

Carpenter, J.E.

1985-01-01

Heliothis zea (Boddie) (Lepidoptera: Noctuidae) males and females were irradiated with substerilizing doses of radiation. These moths were inbred and outcrossed and observed for their ability to reproduce. The inherited deleterious effects resulting from the irradiated P 1 males were recorded for several generations. Larvae from both irradiated (10 krad) and normal parents were compared for their ability to survive under field conditions on whole-stage sweet corn and these results were compared with those from a laboratory study using meridic diet. Irradiated males and females and F 1 males from an irradiated (10 krad) male x normal female cross were released in the field and in field cages and observed for their ability to search/attract and secure a mate. Females that had mated with normal and irradiated (10 krad) males were studied to determine the effect of different mating histories on the subsequent mating propensity of the females. A 10-krad dose of radiation induced deleterious effects which were inherited through the F 2 generation. These radiation-induced deleterious effects were similar to those reported in other species of Lepidoptera. The relationship between the survival of normal larvae and larvae from irradiated parents was similar under laboratory and field rearing conditions. Females mated to normal males and males irradiated with 10 krad had the same mating propensity and experienced the same intermating interval. These effects of substerilizing doses of radiation and inherited sterility on the reproductive ability and behavior of H. zea suggest that a great potential exists for population suppression

The current modes of experience inheritance from famous specialists in traditional Chinese medicine (TCM) include master and disciple, literature review, clinical-epidemiology-based clinical research observation, and analysis and data mining via computer and database technologies. Each mode has its advantages and disadvantages. However, a scientific and instructive experience inheritance mode has not been developed. The advent of the big data era as well as the formation and practice accumulation of the TCM clinical research paradigm in the real world have provided new perspectives, techniques, and methods for inheriting experience from famous TCM specialists. Through continuous exploration and practice, the research group proposes the innovation research mode based on the real-world TCM clinical research paradigm, which involves the inheritance and innovation of the existing modes. This mode is formulated in line with its own development regularity of TCM and is expected to become the main mode of experience inheritance in the clinical field.

Dominantly-inherited Alzheimer's disease is widely hoped to hold the key to developing interventions for sporadic late onset Alzheimer's disease. We use emerging techniques in generative data-driven disease progression modelling to characterize dominantly-inherited Alzheimer's disease progression with unprecedented resolution, and without relying upon familial estimates of years until symptom onset. We retrospectively analysed biomarker data from the sixth data freeze of the Dominantly Inherited Alzheimer Network observational study, including measures of amyloid proteins and neurofibrillary tangles in the brain, regional brain volumes and cortical thicknesses, brain glucose hypometabolism, and cognitive performance from the Mini-Mental State Examination (all adjusted for age, years of education, sex, and head size, as appropriate). Data included 338 participants with known mutation status (211 mutation carriers in three subtypes: 163 PSEN1, 17 PSEN2, and 31 APP) and a baseline visit (age 19-66; up to four visits each, 1.1 ± 1.9 years in duration; spanning 30 years before, to 21 years after, parental age of symptom onset). We used an event-based model to estimate sequences of biomarker changes from baseline data across disease subtypes (mutation groups), and a differential equation model to estimate biomarker trajectories from longitudinal data (up to 66 mutation carriers, all subtypes combined). The two models concur that biomarker abnormality proceeds as follows: amyloid deposition in cortical then subcortical regions (∼24 ± 11 years before onset); phosphorylated tau (17 ± 8 years), tau and amyloid-β changes in cerebrospinal fluid; neurodegeneration first in the putamen and nucleus accumbens (up to 6 ± 2 years); then cognitive decline (7 ± 6 years), cerebral hypometabolism (4 ± 4 years), and further regional neurodegeneration. Our models predicted symptom onset more accurately than predictions that used familial estimates: root mean squared error of 1

Inheritance of resistance to powdery mildew in pea and pathogenesis-related aspects

Directory of Open Access Journals (Sweden)

Ricardo Lima dos Santos

2012-06-01

Full Text Available The inheritance of resistance to powdery mildew in the pea cultivar MK-10 and some histological aspects of infection were assessed. For the inheritance study, F1, F2, backcrosses and F3 generations of MK-10 crossed with two susceptible populations were evaluated. Histological evaluations included percentage of germinated conidia, percentage of conidia that formed appresoria, percentage of conidia that established colonies, and number of haustoria per colony. Segregation ratios obtained in the resistance inheritance study were compared by Chi-square (ײ test and the histological data were analyzed by Tukey's test at 5% probability. It was concluded that resistance of MK-10 to powdery mildew is due to a pair of recessive alleles since it is expressed in the pre-penetration stage and completed by post-penetration localized cellular death, characteristic of the presence of the pair of recessive alleles er1er1.

The views of people with inherited retinal disease are important to help develop health policy and plan services. This study aimed to record levels of understanding of and attitudes to genetic testing for inherited retinal disease, and views on the availability of testing. Telephone questionnaires comprising quantitative and qualitative items were completed with adults with inherited retinal disease. Participants were recruited via postal invitation (response rate 48%), approach at clinic or newsletters of relevant charitable organisations. Questionnaires were completed with 200 participants. Responses indicated that participants' perceived understanding of genetic testing for inherited retinal disease was variable. The majority (90%) considered testing to be good/very good and would be likely to undergo genetic testing (90%) if offered. Most supported the provision of diagnostic (97%) and predictive (92%) testing, but support was less strong for testing as part of reproductive planning. Most (87%) agreed with the statement that testing should be offered only after the individual has received genetic counselling from a professional. Subgroup analyses revealed differences associated with participant age, gender, education level and ethnicity (p<0.02). Participants reported a range of perceived benefits (eg, family planning, access to treatment) and risks (eg, impact upon family relationships, emotional consequences). Adults with inherited retinal disease strongly support the provision of publicly funded genetic testing. Support was stronger for diagnostic and predictive testing than for testing as part of reproductive planning.

Inherited hypothyroidism.

Science.gov (United States)

Jackson, I M

1976-03-01

Familial hypothyroidism results from both thyroidal and extrathyroidal dysfunction. Specific intrathyroidal abnormalities in thyroid hormone synthesis causing goitrous hypothyroidism are iodide trap defect, organification defect, "coupling" defect, iodoprotein defect, and dehalogenase defect. The diagnostic studies for each are outlined utilizing radioiodine(131I) studies. Other causes of cretinism include failure of the thyroid gland to respond to TSH and lack of pituitary TSH (or hypothalamic TRH). The syndrome of peripheral resistance to thyroid hormone is discussed. The diagnosis of inherited hypothyrodism rests on an adequate family history and measurement of both T4 and TSH levels which can be determined in cord blood or peripheral blood from the infant. The importance of early treatment of hypothyroidism in the neonatal period to prevent brain damage is emphasized. The rec:nt discovery of the importance of reverse T3 (RT3) in fetal thyroid metabolism is described, and the possibility of amniocentesis as an aid in prenatal diagnosis is considered. The place of intrauterine administration of thyroid hormone to the fetus at risk from hypothyroidism is uncertain at this time and requires carefully controlled studies and long-term follow-up.

Round Spermatid Injection Rescues Female Lethality of a Paternally Inherited Xist Deletion in Mouse.

Directory of Open Access Journals (Sweden)

2016-10-01

Full Text Available In mouse female preimplantation embryos, the paternal X chromosome (Xp is silenced by imprinted X chromosome inactivation (iXCI. This requires production of the noncoding Xist RNA in cis, from the Xp. The Xist locus on the maternally inherited X chromosome (Xm is refractory to activation due to the presence of an imprint. Paternal inheritance of an Xist deletion (XpΔXist is embryonic lethal to female embryos, due to iXCI abolishment. Here, we circumvented the histone-to-protamine and protamine-to-histone transitions of the paternal genome, by fertilization of oocytes via injection of round spermatids (ROSI. This did not affect initiation of XCI in wild type female embryos. Surprisingly, ROSI using ΔXist round spermatids allowed survival of female embryos. This was accompanied by activation of the intact maternal Xist gene, initiated with delayed kinetics, around the morula stage, resulting in Xm silencing. Maternal Xist gene activation was not observed in ROSI-derived males. In addition, no Xist expression was detected in male and female morulas that developed from oocytes fertilized with mature ΔXist sperm. Finally, the expression of the X-encoded XCI-activator RNF12 was enhanced in both male (wild type and female (wild type as well as XpΔXist ROSI derived embryos, compared to in vivo fertilized embryos. Thus, high RNF12 levels may contribute to the specific activation of maternal Xist in XpΔXist female ROSI embryos, but upregulation of additional Xp derived factors and/or the specific epigenetic constitution of the round spermatid-derived Xp are expected to be more critical. These results illustrate the profound impact of a dysregulated paternal epigenome on embryo development, and we propose that mouse ROSI can be used as a model to study the effects of intergenerational inheritance of epigenetic marks.

Doubly uniparental inheritance of mitochondria as a model system for studying germ line formation.

Directory of Open Access Journals (Sweden)

Liliana Milani

Full Text Available BACKGROUND: Doubly Uniparental Inheritance (DUI of mitochondria occurs when both mothers and fathers are capable of transmitting mitochondria to their offspring, in contrast to the typical Strictly Maternal Inheritance (SMI. DUI was found in some bivalve molluscs, in which two mitochondrial genomes are inherited, one through eggs, the other through sperm. During male embryo development, spermatozoon mitochondria aggregate in proximity of the first cleavage furrow and end up in the primordial germ cells, while they are dispersed in female embryos. METHODOLOGY/PRINCIPAL FINDINGS: We used MitoTracker, microtubule staining and transmission electron microscopy to examine the mechanisms of this unusual distribution of sperm mitochondria in the DUI species Ruditapes philippinarum. Our results suggest that in male embryos the midbody deriving from the mitotic spindle of the first division concurs in positioning the aggregate of sperm mitochondria. Furthermore, an immunocytochemical analysis showed that the germ line determinant Vasa segregates close to the first cleavage furrow. CONCLUSIONS/SIGNIFICANCE: In DUI male embryos, spermatozoon mitochondria aggregate in a stable area on the animal-vegetal axis: in organisms with spiral segmentation this zone is not involved in cleavage, so the aggregation is maintained. Moreover, sperm mitochondria reach the same embryonic area in which also germ plasm is transferred. In 2-blastomere embryos, the segregation of sperm mitochondria in the same region with Vasa suggests their contribution in male germ line formation. In DUI male embryos, M-type mitochondria must be recognized by egg factors to be actively transferred in the germ line, where they become dominant replacing the Balbiani body mitochondria. The typical features of germ line assembly point to a common biological mechanism shared by DUI and SMI organisms. Although the molecular dynamics of the segregation of sperm mitochondria in DUI species are unknown

Frey Sánchez, Antonio Vicente

2014-12-01

Full Text Available Throughout the 13th century a succession of urban revolts took place in al-Andalus, which caused the withdrawal of the Almohad Empire and the establishment of the third taifas, initially led by Muhammad b. Yūsuf b. Hūd al-Mutawakkil. The inability of this emir to hold together this newly-built state, and the continuous insurrections inside and utside of Murcia have led historians to investigate the nature of political power during this period. This article examines each one of these proposals and, on the basis of an analysis of some socio-economic aspects relating to Murcia (being a representative city of al-Andalus and capital of the hūdí movement during the first half of the thirteenth century, proposes a hypothesis on the nature of its power.Durante el siglo XIII se produjo una serie de revueltas urbanas en al-Andalus que ocasionó la retirada del Imperio almohade y la formación de las terceras taifas, inicialmente encabezadas por Muḥammad b.

Inheritance and legal status of an adoptee and adopter in the example of Vranje

2008-01-01

Full Text Available Inheritance and legal status of an adoptee and adopter is frequently identical to the relationship that exists between parents and their biological children. In this sense, it is especially interesting to inquire the inheritance rights of adoptee towards his/hers biological parents and kindred, and on the other hand, adopters and civic kin. From an ethnological standpoint, an adoption is interesting, among other things, because it addresses questions between blood/kin and civic relatedness, expressed fully in inheritance rights. The inheritance law, in practice since 2005 recognizes two types of adoption - total and partial. From an ethnological/anthropological standpoint, the following facts, found at the course of my fieldwork, are indicative- a married couple adopts a male child, usually from the closest husband's blood relatives (an uncle adopts a niece. Female children are rarely adopted, that is, only in cases when the closest blood relatives (through male and female lines have no male descendants. An adoptee inherits an entire family holding property of an adopter. An analysis of the inheritance rights of an adoptee and adopter allows an insight into the understanding of blood relatedness which exists in a consciousness of individuals. It turned out that being childless in a patriarchal social environment, such as Vranje, represents a crisis situation for couples, individuals but also for the whole patrilineal group of relatives. By adoption of a male relative belonging to an agnatic affiliation, the question of inheritance is solved, but also a problem of social and material reproduction of a patrilineal group and continuity of agnatic identity. This, of course, does not mean that an adoption of unrelated male child, especially in a case of total adoption, the same would not be possible. But it appears that the answer is in the fact that in the case of an adoption of unrelated child, there is a weakening of substantial sameness. In the

Inherited diseases commonly emerge within pedigree dog populations, often due to use of repeatedly bred carrier sire(s) within a small gene pool. Accurate family records are usually available making linkage analysis possible. However, there are many factors that are intrinsically difficult about collecting DNA and collating pedigree information from a large canine population. The keys to a successful DNA collection program include (1) the need to establish and maintain support from the pedigree breed clubs and pet owners; (2) committed individual(s) who can devote the considerable amount of time and energy to coordinating sample collection and communicating with breeders and clubs; and (3) providing means by which genotypic and phenotypic information can be easily collected and stored. In this article we described the clinical characteristics of inherited occipital hypoplasia/syringomyelia (Chiari type I malformation) in the cavalier King Charles spaniel and our experiences in establishing a pedigree and DNA database to study the disease.

MAPPIN: a method for annotating, predicting pathogenicity and mode of inheritance for nonsynonymous variants.

Gosalia, Nehal; Economides, Aris N; Dewey, Frederick E; Balasubramanian, Suganthi

2017-10-13

Nonsynonymous single nucleotide variants (nsSNVs) constitute about 50% of known disease-causing mutations and understanding their functional impact is an area of active research. Existing algorithms predict pathogenicity of nsSNVs; however, they are unable to differentiate heterozygous, dominant disease-causing variants from heterozygous carrier variants that lead to disease only in the homozygous state. Here, we present MAPPIN (Method for Annotating, Predicting Pathogenicity, and mode of Inheritance for Nonsynonymous variants), a prediction method which utilizes a random forest algorithm to distinguish between nsSNVs with dominant, recessive, and benign effects. We apply MAPPIN to a set of Mendelian disease-causing mutations and accurately predict pathogenicity for all mutations. Furthermore, MAPPIN predicts mode of inheritance correctly for 70.3% of nsSNVs. MAPPIN also correctly predicts pathogenicity for 87.3% of mutations from the Deciphering Developmental Disorders Study with a 78.5% accuracy for mode of inheritance. When tested on a larger collection of mutations from the Human Gene Mutation Database, MAPPIN is able to significantly discriminate between mutations in known dominant and recessive genes. Finally, we demonstrate that MAPPIN outperforms CADD and Eigen in predicting disease inheritance modes for all validation datasets. To our knowledge, MAPPIN is the first nsSNV pathogenicity prediction algorithm that provides mode of inheritance predictions, adding another layer of information for variant prioritization. © The Author(s) 2017.

Inherited retinal disease represents a significant cause of blindness and visual morbidity worldwide. With the development of emerging molecular technologies, accessible and well-governed repositories of data characterising inherited retinal disease patients is becoming increasingly important. This manuscript introduces such a repository. Participants were recruited from the Retina Australia membership, through the Royal Australian and New Zealand College of Ophthalmologists, and by recruitment of suitable patients attending the Sir Charles Gairdner Hospital visual electrophysiology clinic. Four thousand one hundred ninety-three participants were recruited. All participants were members of families in which the proband was diagnosed with an inherited retinal disease (excluding age-related macular degeneration). Clinical and family information was collected by interview with the participant and by examination of medical records. In 2001, we began collecting DNA from Western Australian participants. In 2009 this activity was extended Australia-wide. Genetic analysis results were stored in the register as they were obtained. The main outcome measurement was the number of DNA samples (with associated phenotypic information) collected from Australian inherited retinal disease-affected families. DNA was obtained from 2873 participants. Retinitis pigmentosa, Stargardt disease and Usher syndrome participants comprised 61.0%, 9.9% and 6.4% of the register, respectively. This resource is a valuable tool for investigating the aetiology of inherited retinal diseases. As new molecular technologies are translated into clinical applications, this well-governed repository of clinical and genetic information will become increasingly relevant for tasks such as identifying candidates for gene-specific clinical trials. © 2012 The Authors.

A test of the transcription model for biased inheritance of yeast mitochondrial DNA.

Science.gov (United States)

Lorimer, H E; Brewer, B J; Fangman, W L

1995-09-01

Two strand-specific origins of replication appear to be required for mammalian mitochondrial DNA (mtDNA) replication. Structural equivalents of these origins are found in the rep sequences of Saccharomyces cerevisiae mtDNA. These striking similarities have contributed to a universal model for the initiation of mtDNA replication in which a primer is created by cleavage of an origin region transcript. Consistent with this model are the properties of deletion mutants of yeast mtDNA ([rho-]) with a high density of reps (HS [rho-]). These mutant mtDNAs are preferentially inherited by the progeny resulting from the mating of HS [rho-] cells with cells containing wild-type mtDNA ([rho+]). This bias is presumed to result from a replication advantage conferred on HS [rho-] mtDNA by the high density of rep sequences acting as origins. To test whether transcription is indeed required for the preferential inheritance of HS [rho-] mtDNA, we deleted the nuclear gene (RPO41) for the mitochondrial RNA polymerase, reducing transcripts by at least 1000-fold. Since [rho-] genomes, but not [rho+] genomes, are stable when RPO41 is deleted, we examined matings between HS [rho-] and neutral [rho-] cells. Neutral [rho-] mtDNAs lack rep sequences and are not preferentially inherited in [rho-] x [rho+] crosses. In HS [rho-] x neutral [rho-] matings, the HS [rho-] mtDNA was preferentially inherited whether both parents were wild type or both were deleted for RPO41. Thus, transcription from the rep promoter does not appear to be necessary for biased inheritance. Our results, and analysis of the literature, suggest that priming by transcription is not a universal mechanism for mtDNA replication initiation.

Land inheritance establishes sibling competition for marriage and reproduction in rural Ethiopia.

Intergenerational transfer of wealth has been proposed as playing a pivotal role in the evolution of human sibling relationships. Sibling rivalry is assumed to be more marked when offspring compete for limited heritable resources, which are crucial for reproductive success (e.g., land and livestock); whereas in the absence of heritable wealth, related siblings may cooperate. To date, comparative studies undertaken to support this evolutionary assumption have been confounded by other socioecological factors, which vary across populations, e.g., food sharing and intergroup conflict. In this article we explore effects of sibling competition and cooperation for agricultural resources, marriage, and reproduction in one contemporary Ethiopian agropastoralist society. Here recent changes in land tenure policy, altering transfers of land from parents to offspring, present a unique framework to test the importance of intergenerational transfers of wealth in driving sibling competition, while controlling for socioeconomic biases. In households where land is inherited, the number of elder brothers reduces a man's agricultural productivity, marriage, and reproductive success, as resources diminish and competition increases with each additional sibling. Where land is not inherited (for males receiving land directly from the government and all females) older siblings do not have a competitive effect and in some instances may be beneficial. This study has wider implications for the evolution of human family sizes. Recent changes in wealth transfers, which have driven sibling competition, may be contributing to an increased desire for smaller family sizes.

Aging is associated with the accumulation of several types of damage: in particular, damage to the proteome. Recent work points to a conserved replicative rejuvenation mechanism that works by preventing the inheritance of damaged and misfolded proteins by specific cells during division. Asymmetric inheritance of misfolded and aggregated proteins has been shown in bacteria and yeast, but relatively little evidence exists for a similar mechanism in mammalian cells. Here, we demonstrate, using long-term 4D imaging, that the vimentin intermediate filament establishes mitotic polarity in mammalian cell lines and mediates the asymmetric partitioning of damaged proteins. We show that mammalian JUNQ inclusion bodies containing soluble misfolded proteins are inherited asymmetrically, similarly to JUNQ quality-control inclusions observed in yeast. Mammalian IPOD-like inclusion bodies, meanwhile, are not always inherited by the same cell as the JUNQ. Our study suggests that the mammalian cytoskeleton and intermediate filaments provide the physical scaffold for asymmetric inheritance of dynamic quality-control JUNQ inclusions. Mammalian IPOD inclusions containing amyloidogenic proteins are not partitioned as effectively during mitosis as their counterparts in yeast. These findings provide a valuable mechanistic basis for studying the process of asymmetric inheritance in mammalian cells, including cells potentially undergoing polar divisions, such as differentiating stem cells and cancer cells.

Inheritance rules for Hierarchical Metadata Based on ISO 19115

Science.gov (United States)

Zabala, A.; Masó, J.; Pons, X.

2012-04-01

Mainly, ISO19115 has been used to describe metadata for datasets and services. Furthermore, ISO19115 standard (as well as the new draft ISO19115-1) includes a conceptual model that allows to describe metadata at different levels of granularity structured in hierarchical levels, both in aggregated resources such as particularly series, datasets, and also in more disaggregated resources such as types of entities (feature type), types of attributes (attribute type), entities (feature instances) and attributes (attribute instances). In theory, to apply a complete metadata structure to all hierarchical levels of metadata, from the whole series to an individual feature attributes, is possible, but to store all metadata at all levels is completely impractical. An inheritance mechanism is needed to store each metadata and quality information at the optimum hierarchical level and to allow an ease and efficient documentation of metadata in both an Earth observation scenario such as a multi-satellite mission multiband imagery, as well as in a complex vector topographical map that includes several feature types separated in layers (e.g. administrative limits, contour lines, edification polygons, road lines, etc). Moreover, and due to the traditional split of maps in tiles due to map handling at detailed scales or due to the satellite characteristics, each of the previous thematic layers (e.g. 1:5000 roads for a country) or band (Landsat-5 TM cover of the Earth) are tiled on several parts (sheets or scenes respectively). According to hierarchy in ISO 19115, the definition of general metadata can be supplemented by spatially specific metadata that, when required, either inherits or overrides the general case (G.1.3). Annex H of this standard states that only metadata exceptions are defined at lower levels, so it is not necessary to generate the full registry of metadata for each level but to link particular values to the general value that they inherit. Conceptually the metadata

Septin-Containing Barriers Control the Differential Inheritance of Cytoplasmic Elements

Full Text Available Fusion of haploid cells of Saccharomyces cerevisiae generates zygotes. We observe that the zygote midzone includes a septin annulus and differentially affects redistribution of supramolecular complexes and organelles. Redistribution across the midzone of supramolecular complexes (polysomes and Sup35p-GFP [PSI+] is unexpectedly delayed relative to soluble proteins; however, in [psi-] × [PSI+] crosses, all buds eventually receive Sup35p-GFP [PSI+]. Encounter between parental mitochondria is further delayed until septins relocate to the bud site, where they are required for repolarization of the actin cytoskeleton. This delay allows rationalization of the longstanding observation that terminal zygotic buds preferentially inherit a single mitochondrial genotype. The rate of redistribution of complexes and organelles determines whether their inheritance will be uniform.

2017-03-28

Factor VII deficiency is the most common among rare inherited autosomal recessive bleeding disorders, and is a chameleon disease due to the lack of a direct correlation between plasma levels of coagulation Factor VII and bleeding manifestations. Clinical phenotypes range from asymptomatic condition-even in homozygous subjects-to severe life-threatening bleedings (central nervous system, gastrointestinal bleeding). Prediction of bleeding risk is thus based on multiple parameters that challenge disease management. Spontaneous or surgical bleedings require accurate treatment schedules, and patients at high risk of severe hemorrhages may need prophylaxis from childhood onwards. The aim of the current review is to depict an updated summary of clinical phenotype, laboratory diagnosis, and treatment of inherited Factor VII deficiency.

Some aspects of the role of rift inheritance on Alpine-type orogens

Science.gov (United States)

Tugend, Julie; Manatschal, Gianreto; Mohn, Geoffroy; Chevrot, Sébastien

2017-04-01

Processes commonly recognized as fundamental for the formation of collisional orogens include oceanic subduction, arc-continent and continent-continent collision. As collisional belts result from the closure of oceanic basins and subsequent inversion of former rifted margins, their formation and evolution may also in theory be closely interlinked with the initial architecture of the former rifted margins. This assumption is indeed more likely to be applicable in the case of Alpine-type orogens, mainly controlled by mechanical processes and mostly devoid of arc-related magmatism. More and more studies from present-day magma-poor rifted margins illustrate the complex evolution of hyperextended domains (i.e. severely thinned continental crust (images across the Pyrenees (PYROPE) and the Alps (CIFALPS) reveal a surprisingly comparable present-day overall crustal and lithospheric structure. Based on the comparison between the two orogens we discuss: (1) the nature and depth of decoupling levels inherited from hyperextension; (2) the implications for restorations and interpretations of orogenic roots (former hyperextended domains vs. lower crust only); and (3) the nature and major role of buttresses in controlling the final stage of collisional processes. Eventually, we discuss the variability of the role of rift-inheritance in building Alpine-type orogens. The Pyrenees seem to represent one extreme, where rift-inheritance is important at different stages of collisional processes. In contrast, in the Alps the role of rift-inheritance is subtler, likely because of its more complex and polyphase compressional deformation history.

2004-01-01

The objectives of this study were to define the clinical syndrome of retinal dysplasia and persistent primary vitreous in Miniature Schnauzer dogs and determine the etiology. We examined 106 Miniature Schnauzers using a biomicroscope and indirect ophthalmoscope. The anterior and posterior segments of affected dogs were photographed. Four enucleated eyes were examined using routine light microscopy and scanning electron microscopy. A pedigree was constructed and related dogs were test-bred to define the mode of inheritance of this syndrome. Congenital retinal dysplasia was confirmed in 24 of 106 related Miniature Schnauzer dogs. Physical and postmortem examinations revealed that congenital abnormalities were limited to the eyes. Biomicroscopic, indirect ophthalmoscopic, and neuro-ophthalmic examinations confirmed that some of these dogs were blind secondary to bilateral retinal dysplasia and detachment (nonattachment) (n = 13), and the remainder had generalized retinal dysplasia (n = 11). Fifteen of these dogs were also diagnosed with unilateral (n = 9) or bilateral (n = 6) persistent hyperplastic primary vitreous. Nutritional, infectious, or toxic etiologies were not evident on physical, postmortem, light microscopic, or transmitting and scanning electron microscopic examination of four affected Miniature Schnauzers. We examined the pedigree and determined that an autosomal recessive mode of inheritance was most likely. Three test-bred litters including those from affected parents, carrier and affected parents, and carrier parents confirmed this mode of inheritance. This study confirms that retinal dysplasia and persistent hyperplastic primary vitreous is a congenital abnormality that is inherited as an autosomal recessive condition in Miniature Schnauzers.

Preimplantation genetic diagnosis (PGD) is an established application of genetic testing in the context of in vitro fertilization. PGD is an alternative method to prenatal diagnosis which aims to prevent the transmission of an inherited disorder to the progeny by implanting only embryos that do not carry genetic predisposition for a particular disease. The aim of this study is to provide an overview of eye disorders for which PGD has been carried out. The European literature search focused on best practices, ethical issues, risks and results of PGD for inherited eye disorders. PGD is performed for a number of ocular disorders; a prerequisite for its application is however, the knowledge of a disease-causing mutation(s). The main advantage of this method is that the couple is not exposed to a decision of whether or not to undergo an abortion. Qualified counselling must be provided prior to the PGD in order to completely understand the risk of disability in any child conceived, consequences of disease manifestation, and advantages as well as limitations of this method. In the group of non-syndromic eye diseases and diseases in which ocular findings dominate, PGD has been performed in European countries for aniridia, choroideremia, congenital fibrosis of extraocular muscles, Leber congenital amaurosis, ocular albinism, retinitis pigmentosa, X-linked retinoschisis, Stargardt disease, blepharophimosis-ptosis-inverse epicanthus syndrome and retinoblastoma. Sexing for X-linked or mitochondrial diseases has been carried out for blue cone monochromatism, choroideremia, familial exudative vitreoretinopathy, Leber hereditary optic neuropathy, macular dystrophy (not further specified), Norrie disease, X-linked congenital stationary night blindness, X-linked retinoschisis and nystagmus (not further specified). In recent years, there has been an increase in potential to use PGD. The spectrum of diseases for this method has widened to include severe inherited eye diseases

Full Text Available This study proposes understanding Agreement and Anti-Agreement in Berber from Multi-Feature Inheritance (MFI account following Branigan’s (2016 recent approach. The study aims to bridge a misunderstanding in the literature where it has been assumed that Feature Inheritance (FI can only account for Agreement relations while Anti-agreement relations can only be established by a direct Agree between C as a probe and its goal. Under MFI, it can be argued that FI can account for all aspects of Agreement/Anti-agreement. The study, therefore, presents a unification of the three mechanisms proposed by Ouali (2008. The new approach is tested on data from Berber.

Full Text Available Background: Thrombophilia is a main predisposition to thrombosis due to a procoagulant state. Several point mutations play key roles in blood-clotting disorders, which are grouped under the term thrombophilia. These thrombophilic mutations are methylenetetrahydrofolate reductase (MTHFR, C677T, and A1298C, factor V Leiden (G1691A, prothrombin gene mutation (factor II, G20210A, and plasminogen activator inhibitor (PAI. In the present study, we assessed the prevalence of the above thrombophilia markers in patients with recurrent pregnancy loss or first and second trimester abortions, infertility, and failed in vitro fertilization (IVF. Methods: This study was conducted among 457 cases those were referred to detect the inherited genetic markers for thrombophilia. Markers for MTHFR, Factor II, and Factor V were assessed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP, and PAI was assessed by Amplification Refractory Mutation System (ARMS-PCR. Results: Two hundred sixty cases (56.89% were diagnosed as having at least one thrombophilia marker, whereas 197 cases (43.11% had no thrombophilia markers and were normal. Conclusion: According to the current study, the pattern of abnormal genetic markers for thrombophilia in northeastern Iran demonstrates the importance of genetic evaluations in patients who show clinical abnormalities with recurrent spontaneous abortion (RSA or other serious obstetric complications.

Ancestral dichlorodiphenyltrichloroethane (DDT) exposure promotes epigenetic transgenerational inheritance of obesity

Science.gov (United States)

2013-01-01

Background Ancestral environmental exposures to a variety of environmental factors and toxicants have been shown to promote the epigenetic transgenerational inheritance of adult onset disease. The present work examined the potential transgenerational actions of the insecticide dichlorodiphenyltrichloroethane (DDT) on obesity and associated disease. Methods Outbred gestating female rats were transiently exposed to a vehicle control or DDT and the F1 generation offspring bred to generate the F2 generation and F2 generation bred to generate the F3 generation. The F1 and F3 generation control and DDT lineage rats were aged and various pathologies investigated. The F3 generation male sperm were collected to investigate methylation between the control and DDT lineage male sperm. Results The F1 generation offspring (directly exposed as a fetus) derived from the F0 generation exposed gestating female rats were not found to develop obesity. The F1 generation DDT lineage animals did develop kidney disease, prostate disease, ovary disease and tumor development as adults. Interestingly, the F3 generation (great grand-offspring) had over 50% of males and females develop obesity. Several transgenerational diseases previously shown to be associated with metabolic syndrome and obesity were observed in the testis, ovary and kidney. The transgenerational transmission of disease was through both female (egg) and male (sperm) germlines. F3 generation sperm epimutations, differential DNA methylation regions (DMR), induced by DDT were identified. A number of the genes associated with the DMR have previously been shown to be associated with obesity. Conclusions Observations indicate ancestral exposure to DDT can promote obesity and associated disease transgenerationally. The etiology of disease such as obesity may be in part due to environmentally induced epigenetic transgenerational inheritance. PMID:24228800

Full Text Available Abstract Background Mitochondrial function is impaired in Parkinson's disease (PD and may contribute to the pathogenesis of PD, but the causes of mitochondrial impairment in PD are unknown. Mitochondrial dysfunction is recapitulated in cell lines expressing mitochondrial DNA (mtDNA from PD patients, implicating mtDNA variants or mutations, though the role of mtDNA variants or mutations in PD risk remains unclear. We investigated the potential contribution of mtDNA variants or mutations to the risk of PD. Methods We examined the possibility of a maternal inheritance bias as well as the association between mitochondrial haplogroups and maternal inheritance and disease risk in a case-control study of 168 multiplex PD families in which the proband and one parent were diagnosed with PD. 2-tailed Fisher Exact Tests and McNemar's tests were used to compare allele frequencies, and a t-test to compare ages of onset. Results The frequency of affected mothers of the proband with PD (83/167, 49.4% was not significantly different from the frequency of affected females of the proband generation (115/259, 44.4% (Odds Ratio 1.22; 95%CI 0.83 - 1.81. After correcting for multiple tests, there were no significant differences in the frequencies of mitochondrial haplogroups or of the 10398G complex I gene polymorphism in PD patients compared to controls, and no significant associations with age of onset of PD. Mitochondrial haplogroup and 10398G polymorphism frequencies were similar in probands having an affected father as compared to probands having an affected mother. Conclusions These data fail to demonstrate a bias towards maternal inheritance in familial PD. Consistent with this, we find no association of common haplogroup-defining mtDNA variants or for the 10398G variant with the risk of PD. However, these data do not exclude a role for mtDNA variants in other populations, and it remains possible that other inherited mitochondrial DNA variants, or somatic m

Full Text Available Vascular access thrombosis is one of the major causes of morbidity in patients maintained on chronic hemodialysis. Thrombophilia has been recognized as a risk factor of vascular access thrombosis. The authors report a case of inherited protein S deficiency associated with vascular access thrombotic events. DNA sequence analysis of the PROS1 gene identified a novel heterozygous nonsense mutation in exon 10 by transition of AAG (lysine to TAG (stop codon at codon 473 (c.1417A>T, p.K473X. Results from the study suggest that the inherited protein S deficiency due to a PROS1 gene mutation may cause vascular access thrombosis in hemodialysis patients.

Using lod-score differences to determine mode of inheritance: A simple, robust method even in the presence of heterogeneity and reduced penetrance

Determining the mode of inheritance is often difficult under the best of circumstances, but when segregation analysis is used, the problems of ambiguous ascertainment procedures, reduced penetrance, heterogeneity, and misdiagnosis make mode-of-inheritance determinations even more unreliable. The mode of inheritance can also be determined using a linkage-based method and association-based methods, which can overcome many of these problems. In this work, we determined how much information is necessary to reliably determine the mode of inheritance from linkage data when heterogeneity and reduced penetrance are present in the data set. We generated data sets under both dominant and recessive inheritance with reduced penetrance and with varying fractions of linked and unlinked families. We then analyzed those data sets, assuming reduced penetrance, both dominant and recessive inheritance, and no heterogeneity. We investigated the reliability of two methods for determining the mode of inheritance from the linkage data. The first method examined the difference ({Delta}) between the maximum lod scores calculated under the two mode-of-inheritance assumptions. We found that if {Delta} was >1.5, then the higher of the two maximum lod scores reflected the correct mode of inheritance with high reliability and that a {Delta} of 2.5 appeared to practically guarantee a correct mode-of-inheritance inference. Furthermore, this reliability appeared to be virtually independent of {alpha}, the fraction of linked families in the data set. The second method we tested was based on choosing the higher of the two maximum lod scores calculated under the different mode-of-inheritance assumptions. This method became unreliable as {alpha} decreased. These results suggest that the mode of inheritance can be inferred from linkage data with high reliability, even in the presence of heterogeneity and reduced penetrance. 12 refs., 3 figs., 2 tabs.

Inheritance of sterility in Dysdercus koenigii F. (Hemiptera: Pyrrhocoridae)

Harwalkar, M.R.; Rahalkar, G.W.

1979-01-01

It has been suggested that for the control of Lepidopterous populations, release of fully competitive partially sterile males would be more advantageous than the release of completely sterile males. This suggestion is based on the fact, elucidated in many studies, that partially sterilized males mated to normal females produce totally sterile or partially sterile progeny. In Hemiptera too, F 1 progeny of partially sterile males has been shown to inherit sterility. Individual impact of sterility inherited by either sex of the F 1 progeny on population growth has been studied in an hemipteran insect Dysdercus koenigii. A dose of 7 krad induces near-complete sterility in males. When males irradiated with substerilizing doses of 1,2 and 3 krad were crossed with normal females, F 1 progeny of both sexes was partially sterile : the female being more sterile than the males. When the F 1 progeny was intercrossed, there was enhanced reduction in progeny production. (auth.)

Demonstration of paternal inheritance of plastids in Picea (Pinaceae)

Stine, M.

1988-01-01

Chloroplast DNA (cpDNA) was purified from Picea glauca, P. pungens, P. engelmannii, and P. omorika, and was digested with several restriction endonucleases. Interspecific restriction fragment length polymorphisms (RFLPs) of cpDNA were identified. The RFLPs were identified as cpDNA by the hybridization of cloned, 32 -P labeled, petunia cpDNA to the polymorphic bands, and by the lack of hybridization of a cloned and labeled mtDNA probe from maize. Chloroplast DNA RFLPs that showed no intraspecific variation when examined across the natural range for each species, were used as markers to follow the inheritance of plastids in interspecific hybrids. The inheritance of plastids was determined for F 1 -hybrids from reciprocal crosses of P. glauca and P. pungens, P. glauca and P. omorika, and F 1 -hybrids of P. engelmannii x pungens. All 31 F 1 -hybrids examined showed the cpDNA genotypes of the pollen parent, or the paternal species

The mechanisms of feature inheritance as predicted by a systems-level model of visual attention and decision making.

Feature inheritance provides evidence that properties of an invisible target stimulus can be attached to a following mask. We apply a systemslevel model of attention and decision making to explore the influence of memory and feedback connections in feature inheritance. We find that the presence of feedback loops alone is sufficient to account for feature inheritance. Although our simulations do not cover all experimental variations and focus only on the general principle, our result appears of specific interest since the model was designed for a completely different purpose than to explain feature inheritance. We suggest that feedback is an important property in visual perception and provide a description of its mechanism and its role in perception.

Metabolism and insulin signaling in common metabolic disorders and inherited insulin resistance.

Højlund, Kurt

2014-07-01

Type 2 diabetes, obesity and polycystic ovary syndrome (PCOS) are common metabolic disorders which are observed with increasing prevalences, and which are caused by a complex interplay between genetic and environmental factors, including increased calorie intake and physical inactivity. These metabolic disorders are all characterized by reduced plasma adiponectin and insulin resistance in peripheral tissues. Quantitatively skeletal muscle is the major site of insulin resistance. Both low plasma adiponectin and insulin resistance contribute to an increased risk of type 2 diabetes and cardiovascular disease. In several studies, we have investigated insulin action on glucose and lipid metabolism, and at the molecular level, insulin signaling to glucose transport and glycogen synthesis in skeletal muscle from healthy individuals and in obesity, PCOS and type 2 diabetes. Moreover, we have described a novel syndrome characterized by postprandial hyperinsulinemic hypoglycemia and insulin resistance. This syndrome is caused by a mutation in the tyrosine kinase domain of the insulin receptor gene (INSR). We have studied individuals with this mutation as a model of inherited insulin resistance. Type 2 diabetes, obesity and PCOS are characterized by pronounced defects in the insulin-stimulated glucose uptake, in particular glycogen synthesis and to a lesser extent glucose oxidation, and the ability of insulin to suppress lipid oxidation. In inherited insulin resistance, however, only insulin action on glucose uptake and glycogen synthesis is impaired. This suggests that the defects in glucose and lipid oxidation in the common metabolic disorders are secondary to other factors. In young women with PCOS, the degree of insulin resistance was similar to that seen in middle-aged patients with type 2 diabetes. This supports the hypothesis of an unique pathogenesis of insulin resistance in PCOS. Insulin in physiological concentrations stimulates glucose uptake in human skeletal

Inherited metabolic liver diseases in infants and children: an overview

Full Text Available Inborn errors of metabolism, which affect the liver are a large, continuously increasing group of diseases. Their clinical onset can occur at any age, from intrauterine period presenting as liver failure already at birth to late adulthood. Inherited metabolic disorders must be considered in differential diagnosis of every unexplained liver disease. Specific diagnostic work-up for either their confirmation or exclusion should start immediately since any postponing can result in delayed diagnosis and death or irreversible disability. This can be particularly painful while many inherited metabolic liver diseases are relatively easily treatable if diagnosed on time, for instance galactosemia or hereditary fructose intolerance by simple dietary means. Any unexplained liver disease, even one looking initially benign, should be considered as a potential liver failure and therefore should deserve proper attention. Diagnosis in neonates is additionally complicated because of the factors which can mask liver disease, such as physiological neonatal jaundice, normally relatively enlarged liver and increased transaminases at that age. In everyday practice, in order to reveal the etiology, it is useful to classify and distinguish some clinical patterns which, together with a few routine, widely available laboratory tests (aminotransferases, prothrombine time, albumin, gammaGT, total and conjugated bilirubin, ammonia, alkaline phosphatase and glucose make the search for the cause much easier. These patterns are isolated hyperbilirubinemia, syndrome of cholestasis in early infancy, hepatocellular jaundice, Reye syndrome, portal cirrhosis and isolated hepatomegaly. Despite the fact that some diseases can present with more than one pattern (for instance, alpha-1-antitrypsin deficiency as infantile cholestasis, but also as hepatocellular jaundice, and that in some disesases one pattern can evolve into another (for instance, Wilson disease from hepatocellular

To investigate the molecular mechanisms involved in coagulation factor expression and/or function during direct hyperplasia (DH)-mediated liver regeneration. Direct hyperplasia-mediated liver regeneration was induced in female C57BL/6 mice by administering 1,4-bis[2-(3,5-dichloropyridyloxy)] benzene (TCPOBOP), a representative hepatomitogen. Mice were weighed and sacrificed at various time points [Day 0 (D0: prior to injection), 3 h, D1, D2, D3, and D10] after TCPOBOP administration to obtain liver and blood samples. Using the RNA samples extracted from the liver, a comprehensive analysis was performed on the hepatic gene expression profiling of coagulation-related factors by real-time RT-PCR (fibrinogen, prothrombin, factors V, VII, VIII, IX, X, XI, XII, XIIIbeta, plasminogen, antithrombin, protein C, protein S, ADAMTS13, and VWF). The corresponding plasma levels of coagulation factors (fibrinogen, prothrombin, factors V, VII, VIII, IX, X, XI, XII, XIII, and VWF) were also analyzed and compared with their mRNA levels. Gavage administration of TCPOBOP (3 mg/kg body weight) resulted in a marked and gradual increase in the weight of the mouse livers relative to the total body weight to 220% by D10 relative to the D0 (control) ratios. At the peak of liver regeneration (D1 and D2), the gene expression levels for most of the coagulation-related factors (fibrinogen, prothrombin, factors V, VII, VIII, IX, XI, XII, XIIIbeta, plasminogen, antithrombin, protein C, ADAMTS13, VWF) were found to be down-regulated in a time-dependent manner, and gradually recovered by D10 to the basal levels. Only mRNA levels of factor X and protein S failed to show any decrease during the regenerative phase. As for the plasma levels, 5 clotting factors (prothrombin, factors VIII, IX, XI, and XII) demonstrated a significant decrease (Pfactors, factor IX and factor XI showed the most dramatic decline in their activities by about 50% at D2 compared to the basal levels, and these reductions in

An inherited skeletal disease with gross and microscopic features of rickets has been diagnosed in Corriedale sheep in New Zealand. The aim of this study was to quantify the changes present in tibia from sheep with inherited rickets using peripheral quantitative computed tomography. In affected sheep, scans in the proximal tibia, where metaphysis becomes diaphysis, showed significantly greater trabecular bone mineral content (BMC) and bone mineral density (BMD). The sheep with inherited rickets had significantly greater BMC and bone area in the mid-diaphysis of the proximal tibia compared to control sheep. However, BMD in the mid-diaphysis was significantly less in affected sheep than in controls, due to the greater cortical area and lower voxel density values in affected sheep. From this it was concluded that the increased strain on under-mineralised bone in sheep with inherited rickets led to increased bone mass in an attempt to improve bone strength.

Building on a tripartite model of capitals necessary to perform productive activities and on work suggesting that cumulative (dis-)advantage processes are important mechanisms for life course inequalities, our study set out to investigate the potential role of family social background and inheritance in later life volunteering. We hypothesized that older individuals who inherited work-relevant economic and cultural capitals from their family of origin are more likely to be engaged in voluntary activities than their counterparts with a less advantageous family social background. Our main findings from the analysis of a representative sample of community-dwelling Israelis aged 50 and over provide strong support for this hypothesis: the likelihood to volunteer is significantly higher among those who received substantial financial transfers from their family of origin ("inherited economic capital") and among those having a "white collar" parental background ("inherited cultural capital"). We conclude with perspectives for future research. © The Author(s) 2014.

Modelling the co-evolution of indirect genetic effects and inherited variability.

When individuals interact, their phenotypes may be affected not only by their own genes but also by genes in their social partners. This phenomenon is known as Indirect Genetic Effects (IGEs). In aquaculture species and some plants, however, competition not only affects trait levels of individuals, but also inflates variability of trait values among individuals. In the field of quantitative genetics, the variability of trait values has been studied as a quantitative trait in itself, and is often referred to as inherited variability. Such studies, however, consider only the genetic effect of the focal individual on trait variability and do not make a connection to competition. Although the observed phenotypic relationship between competition and variability suggests an underlying genetic relationship, the current quantitative genetic models of IGE and inherited variability do not allow for such a relationship. The lack of quantitative genetic models that connect IGEs to inherited variability limits our understanding of the potential of variability to respond to selection, both in nature and agriculture. Models of trait levels, for example, show that IGEs may considerably change heritable variation in trait values. Currently, we lack the tools to investigate whether this result extends to variability of trait values. Here we present a model that integrates IGEs and inherited variability. In this model, the target phenotype, say growth rate, is a function of the genetic and environmental effects of the focal individual and of the difference in trait value between the social partner and the focal individual, multiplied by a regression coefficient. The regression coefficient is a genetic trait, which is a measure of cooperation; a negative value indicates competition, a positive value cooperation, and an increasing value due to selection indicates the evolution of cooperation. In contrast to the existing quantitative genetic models, our model allows for co-evolution of

Full Text Available Abstract Background Triglyceride/HDL cholesterol ratio (TG/HDL-C is considered as a risk factor for cardiovascular events. Genetic components were important in controlling the variation in western countries. But the mode of inheritance and family aggregation patterns were still unknown among Asian-Pacific countries. This study, based on families recruited from community and hospital, is aimed to investigate the mode of inheritance, heritability and shared environmental factors in controlling TG/HDL-C. Results Two populations, one from community-based families (n = 988, 894 parent-offspring and 453 sibling pairs and the other from hospital-based families (n = 1313, 76 parent-offspring and 52 sibling pairs were sampled. The population in hospital-based families had higher mean age values than community-based families (54.7 vs. 34.0. Logarithmic transformed TG/ HDL-C values, after adjusted by age, gender and body mass index, were for genetic analyses. Significant parent-offspring and sibling correlations were also found in both samples. The parent-offspring correlation coefficient was higher in the hospital-based families than in the community-based families. Genetic heritability was higher in community-based families (0.338 ± 0.114, p = 0.002, but the common shared environmental factor was higher in hospital-based families (0.203 ± 0.042, p Conclusion Variations of TG/HDL-C in the normal ranges were likely to be influenced by multiple factors, including environmental and genetic components. Higher genetic factors were proved in younger community-based families than in older hospital-based families.

Full Text Available Abstract Background Benign neutropenia, i.e., neutropenia not associated with an increased risk of infection, may result in serious medical consequences when a 'standard' definition of neutropenia (absolute neutrophil count (ANC 9cells/L is universally applied to all races. The aims of this study were to determine the prevalence of benign neutropenia among healthy Arabs and evaluate its mode of inheritance. Methods ANCs were studied prospectively amongst a healthy indigenous population (n = 1032 from the United Arab Emirates undergoing a nation-wide sickle-cell and thalassemia screening program. The mean neutrophil count and the prevalence of benign neutropenia were compared by age, sex and amongst various tribes. Results The mean neutrophil count (× 109cells/L was 3.3 (range 0.95–7.6. Benign neutropenia was present in 110 (10.7% subjects of whom 24 (2.3% individuals had moderate neutropenia (ANC 0.5 – 1.0 × 109 cells/L. In the 22 tribe-family groups, the prevalence of benign neutropenia varied between 0% and 38%. Benign neutropenia showed no difference in the frequency amongst the sexes (p = 0.23 and it was independent of age (Spearman's rho = 0.05, p = 0.13. The age-related mean neutrophil count was the lowest in Arabs when compared with other ethnic groups (Blacks, Europeans and Mexicans. The inheritance of benign neutropenia was consistent with an autosomal dominant pattern; however, the diversity of observed phenotypes suggested the presence of more than one genetic variant for this trait. Conclusion Arabs have a high prevalence of benign neutropenia that may be inherited as an autosomal dominant trait.

In this paper, we conduct innovation strategy research of the Yunnan image in the modern entertainment channels based on regression and inheritance of culture. The concept of culture and complicated contents as simply includes material culture and spiritual culture. Cultural inheritance is the process of acculturation a nation it not only is the transmission of national culture, the inheritance and development that also can be refl ected by many indexes. Multicultural education theory formed in the American civil rights movement in the 1960s. Multicultural education theory is that, when the mainstream national culture and the minority subculture in contact, every culture shall be entitled to retain their own cultural traits. Our research integrate the regression and inheritance of culture to then propose the innovation strategy research of the Yunnan image that will promote further development of the corresponding and related industry.

Inherited retarded eruption in the permanent dentition.

Science.gov (United States)

Rasmussen, P; Kotsaki, A

1997-01-01

The term retarded eruption, may be used in cases where eruption is inhibited, causing an interruption in the coordination of tooth formation and tooth eruption. The phenomenon may be local or general, and several etiological factors for retarded eruption have been listed, comprising a lack of space, ankylosis, cysts, supernumerary teeth, hormone and vitamin deficiencies and several developmental disturbances and syndromes. The present paper describes several cases of retarded eruption where no factors other than inheritance have been evident. So far 14 cases have been evaluated, 9 boys and 5 girls. In addition several cases have been registered among parents and grandparents of the probands. Typical features are: retarded eruption, defined as more than 3 SD beyond mean eruption figures, comprises all teeth in the permanent dentition, and in 5 cases also second primary molars. The chronology of tooth formation are within normal limits. Consequently the teeth finish development still laying deeply buried in the jaws, often in aberrant positions and with curves or hooks on the roots. When the teeth finally get the "signal" for eruption, 5-15 years beyond normal eruption time, they move rather quickly into right positions, despite the long eruption paths and the hooked roots. Permanent teeth without, as well as with predecessors, are affected. Extraction of predecessors does not seem to provoke eruption. The main features in management are to take care of the primary teeth, to improve-esthetics, and offer surgery and orthodontics when needed. Analyses of pedigrees indicates that the genetic transmittance may be autosomal dominant as both sexes are affected, about half of the siblings show the trait, and the trait shows continuity through generations.

This memory effect, which can be found even in the absence of the original stress, has an epigenetic basis, through molecular mechanisms that take place at the chromatin and DNA level but do not imply changes in the DNA sequence. Many epigenetic mechanisms have been described and involve covalent modifications on the DNA and histones, such as DNA methylation, histone acetylation and methylation, and RNAi dependent silencing mechanisms. Some of these chromatin modifications need to be stable through cell division in order to be truly epigenetic. During DNA replication, histones are recycled during the formation of the new nucleosomes and this process is tightly regulated. Perturbations to the DNA replication process and/or the recycling of histones lead to epigenetic changes. In this mini-review, we discuss recent evidence aimed at linking DNA replication process to epigenetic inheritance in plants.

Risk factors for cancer

International Nuclear Information System (INIS)

Lyman, G.H.

It is no longer reasonable to divide cancers into those that are genetic in origin and those that are environmental in origin. With rare exception, carcinogenesis involves environmental factors that directly or indirectly exert a change in the cell's genome. Virtually all causes of cancer are multifactorial, sometimes involving an inherited predisposition to the carcinogenic effects of environmental factors, which include chemicals, ionizing radiation, and oncogenic virus. Carcinogenesis is a multistep process including induction, promotion, and progression. Initiation requires an irreversible change in the cellular genome, whereas promotion is commonly associated with prolonged and reversible exposure. Tumor progression results in genotypic and phenotypic changes associated with tumor growth, invasion, and metastasis. Most information on human cancer risk is based on epidemiologic studies involving both exposed and unexposed individuals. The quality of such studies depends on their ability to assess the strength of any association of exposure and disease and careful attention to any potential bias. Few cancers are inherited in a Mendelian fashion. Several preneoplastic conditions, however, are clearly inherited and several malignancies demonstrate weak familial patterns. Environmental factors may exert their effect on DNA in a random fashion, but certain consistent changes, including specific translocations of genetic information, are often found. Currently, there is great interest in the close proximity of certain oncogenes governing growth control to the consistent chromosomal changes observed. Such changes may represent a final common pathway of action for environmental carcinogens. Sufficient laboratory and epidemiologic evidence exists to establish a causal association of several chemical agents with cancer

Using lod-score differences to determine mode of inheritance: a simple, robust method even in the presence of heterogeneity and reduced penetrance.

Determining the mode of inheritance is often difficult under the best of circumstances, but when segregation analysis is used, the problems of ambiguous ascertainment procedures, reduced penetrance, heterogeneity, and misdiagnosis make mode-of-inheritance determinations even more unreliable. The mode of inheritance can also be determined using a linkage-based method (maximized maximum lod score or mod score) and association-based methods, which can overcome many of these problems. In this work, we determined how much information is necessary to reliably determine the mode of inheritance from linkage data when heterogeneity and reduced penetrance are present in the data set. We generated data sets under both dominant and recessive inheritance with reduced penetrance and with varying fractions of linked and unlinked families. We then analyzed those data sets, assuming reduced penetrance, both dominant and recessive inheritance, and no heterogeneity. We investigated the reliability of two methods for determining the mode of inheritance from the linkage data. The first method examined the difference (delta) between the maximum lod scores calculated under the two mode-of-inheritance assumptions. We found that if delta was > 1.5, then the higher of the two maximum lod scores reflected the correct mode of inheritance with high reliability and that a delta of 2.5 appeared to practically guarantee a correct mode-of-inheritance inference. Furthermore, this reliability appeared to be virtually independent of alpha, the fraction of linked families in the data set, although the reliability decreased slightly as alpha fell below .50.(ABSTRACT TRUNCATED AT 250 WORDS)

Proteomics analysis for asymmetric inheritance of preexisting proteins between mother and daughter cells in budding yeast.

In budding yeast, a mother cell can produce a finite number of daughter cells over its life. The accumulation of a variety of types of damaged components has an impact on the aging process. Asymmetrical inheritance during cell division causes these aberrant intracellular constituents to be retained in mother cells and prevents them from segregating to daughter cells. However, the understanding of asymmetrical inheritance of individual proteins that are damaged or old age, and their relevance to the aging process, has been limited. The aim of this study is to propose a proteomics strategy for asymmetrical inheritance of preexisting proteins between mother and daughter cells. During synchronous culture for one generation, newly synthesized proteins were labeled with stable isotope amino acids to discriminate preexisting proteins originally expressed in mother cells, followed by separation of mother and daughter cells using a conventional method based on biotin labeling. Isotope incorporation ratios for individual proteins were quantified using mass spectrometry. We successfully identified 21 proteins whose preexisting versions were asymmetrically inherited in mother cells, including plasma membrane transporter involved in the aging process and organelle-anchoring proteins related to the stress response to misfolded proteins. Thus, our approach would be useful for making catalog of asymmetrically inherited proteins. © 2017 Molecular Biology Society of Japan and John Wiley & Sons Australia, Ltd.

Prevalence of Co-Inheritance of Alpha-Thalassemia with Beta-Thalassemia and Beta-Hemoglobinopathy in Ahvaz City

2013-09-01

Full Text Available Background: Co-inheritance of hemoglobin gene defects is a rare important status that can lead to double heterozygote or homozygote with significant clinical manifestations. Such conditions can be observed in co-inheritance of alpha-thalassemia with beta-thalassemia or hemoglobinopathy. The aim of this study was to evaluate the prevalence of alpha-thalassemia with beta-thalassemia and hemoglobinopathy co-inheritance in a considerable number of Iranian.   Methods: This descriptive study was performed on patients with abnormal hematological findings in favor of alpha-thalassemia, beta-thalassemia or beta-hemoglobinopathies. Patients with low MCV and MCH levels and high HbA2 (>3.5 and those with low MCV and MCH and normal or low HbA2 were candidate for molecular analysis for beta and alpha thalassemia respectively. Abnormal Hb electrophoresis was diagnostic criteria for molecular analysis of beta-hemoglobinopathies.   Results: Study revealed that more than half of the patients with alpha-thalassemia affected simultaneously by beta-thalassemia and about thirty percent inherited beta-hemoglobinopathies. Among patients with beta-thalassemia, HbSCd6 (A-T was the most common mutation and in alpha-thalassemic patients α 3.7 was the commonest mutation.   Conclusion: Relatively high prevalence of co-inheritance of alfa-thalassemia with beta-thalassemia and hemoglobinopathies reflect the necessity of genetic consulting and molecular analysis in diagnosis of such conditions.

Peterus Thajeb

2006-09-01

Full Text Available Mitochondrial disorders are heterogeneous systemic ailments that are most often caused by maternal inheritance of a variety of mutations of the mitochondrial (mt DNA. Paternal inheritance and somatic mutation are rare. The disorders are well recognized not only for the genotypic heterogeneity, but also the phenotypic variation among the affected members of a single family. The genotype-phenotype correlation of the diversity of the syndromic and non-syndromic features of mitochondrial disorders are discussed. Some aspects of the molecular mechanisms of this heterogeneity, and the histopathologic findings are highlighted.

The introduction of array-CGH analysis is allowing the identification of novel genomic disorders. However, this new high-resolution technique is also opening novel diagnostic challenges when inherited private CNVs of unclear clinical significance are found. Oligo array-CGH analysis of 84 patients with mild to severe mental retardation associated with multiple congenital anomalies revealed 10 private CNVs inherited from a healthy parent. Three were deletions (7q31, 14q21.1, Xq25) and seven duplications (12p11.22, 12q21.31, 13q31.1, 17q12, Xp22.31, Xq28) ranging between 0.1 and 3.8Mb. Six rearrangements were not polymorphic. Four overlapped polymorphic regions to the extent of 10-61%. In one case the size was different between the proband and the healthy relative. Three small rearrangements were gene deserts. The remaining seven had a mean gene content of five (ranging from 1 to 18). None of the rearranged genes is known to be imprinted. Three disease-genes were found in three different cases: KAL1 in dupXp22.31, STS in another dupXp22.31 and TCF2 in dup17q12. The patient carrying the last duplication presents sex reversal, Peters' anomaly and renal cysts and the duplication is located 4Mb away from the HSD17B1 gene, coding a key enzyme of testosterone biosynthesis. Considering the overlap with polymorphic regions, size-identity within the family, gene content, kind of rearrangement and size of rearrangement we suggest that at least in five cases the relationship to the phenotype has not to be excluded. We recommend to maintain caution when asserting that chromosomal abnormalities inherited from a healthy parent are benign. A more complex mechanism may in fact be involved, such as a concurrent variation in the other allele or in another chromosome that influences the phenotype.

Computer model for predicting the effect of inherited sterility on population growth

International Nuclear Information System (INIS)

Carpenter, J.E.; Layton, R.C.

1993-01-01

A Fortran based computer program was developed to facilitate modelling different inherited sterility data sets under various paradigms. The model was designed to allow variable input for several different parameters, such as rate of increase per generation, release ratio and initial population levels, reproductive rates and sex ratios resulting from different matings, and the number of nights a female is active in mating and oviposition. The model and computer program should be valuable tools for recognizing areas in which information is lacking and for identifying the effect that different parameters can have on the efficacy of the inherited sterility method.

Dominant inheritance of field-evolved resistance to Bt corn in Busseolafusca.

Directory of Open Access Journals (Sweden)

Pascal Campagne

Full Text Available Transgenic crops expressing Bacillus thuringiensis (Bt toxins have been adopted worldwide, notably in developing countries. In spite of their success in controlling target pests while allowing a substantial reduction of insecticide use, the sustainable control of these pest populations is threatened by the evolution of resistance. The implementation of the "high dose/refuge" strategy for managing insect resistance in transgenic crops aims at delaying the evolution of resistance to Bt crops in pest populations by promoting survival of susceptible insects. However, a crucial condition for the "high dose/refuge" strategy to be efficient is that the inheritance of resistance should be functionally recessive. Busseolafusca developed high levels of resistance to the Bt toxin Cry 1Ab expressed in Bt corn in South Africa. To test whether the inheritance of B. fusca resistance to the Bt toxin could be considered recessive we performed controlled crosses with this pest and evaluated its survival on Bt and non-Bt corn. Results show that resistance of B. fusca to Bt corn is dominant, which refutes the hypothesis of recessive inheritance. Survival on Bt corn was not lower than on non-Bt corn for both resistant larvae and the F1 progeny from resistant × susceptible parents. Hence, resistance management strategies of B. fusca to Bt corn must address non-recessive resistance.

They say it runs in the family: diabetes and inheritance in Oaxaca, Mexico.

Science.gov (United States)

Everett, Margaret

2011-06-01

The globalization of genetic discourses, especially where ethnicity is treated as a "risk factor" for disease, deserves special attention and concern. In countries such as Mexico, with large indigenous populations, the consequences of the Thrifty Genotype hypothesis and/or the attribution of type 2 diabetes to "family history" may be especially detrimental to poor rural communities, playing as they do into existing racial hierarchies. Based on semi-structured interviews with doctors and patients in a public clinic in a community near Oaxaca, Mexico, the study examines etiologies for type 2 diabetes. While notions of genetic inheritance and family history figure prominently in government and public health discourse, the "explanatory model" of patients places most emphasis on strong emotions, traumatic events, and dietary factors. Clinic doctors emphasize diet and lifestyle factors. The diffusion of "genetic risk" has had little impact on doctor-patient interactions in this community, but can be clearly seen in academic research, government policy, and medical specialties in the region, raising concerns about whether or not interventions will be directed at the social determinants of this growing health concern.

Prions are novel kinds of hereditary units, relying solely on proteins, that are infectious and inherited in a non-Mendelian fashion. To date, they are either based on autocatalytic modification of a 3D conformation or on autocatalytic cleavage. Here, we provide further evidence that in the filamentous fungus Podospora anserina, a MAP kinase cascade is probably able to self-activate and generate C, a hereditary unit that bears many similarities to prions and triggers cell degeneration. We show that in addition to the MAPKKK gene, both the MAPKK and MAPK genes are necessary for the propagation of C, and that overexpression of MAPK as that of MAPKKK facilitates the appearance of C. We also show that a correlation exists between the presence of C and localization of the MAPK inside nuclei. These data emphasize the resemblance between prions and a self-positively regulated cascade in terms of their transmission. This thus further expands the concept of protein-base inheritance to regulatory networks that have the ability to self-activate.

O moio-medida e o moio dos preços em Portugal nos séculos Xl a XIII

Seabra Lopes, Luis

2005-06-01

Full Text Available In this paper, the value of the modius (modio, moyo, moio in Portugal in the 11th to the 13th centuries is studied. By this time, the modius was both a measure of capacity and a unit used in the specification of prices. The author concludes that, while the modius-measure had a capacity not under the horse charge (210 to 220 litters in the legal systems used in Portugal from the end of the 11th century onwards, some smaller modii continued to be used in rural areas far away from the main urban centers. These smaller modii had a capacity around 50 to 75 litters. With respect to the modius-price, the information gathered by the author indicates a value between 25 and 55 litters of cereal. Therefore, it becomes clear that the modius-price was not equivalent to the standard modius-measure, although it could be equivalent to the smaller modii still in use in rural areas. The gathered evidence also suggests that, from the 10th to the 13th centuries, independently of inflation, the modius-price remained approximately equivalent to the currency unit known as solidus

Neste artigo, estuda-se o valor do moio (modius, modio, moyo em Portugal nos séculos XI a XIII.

Estes moios mais pequenos tinham capacidades em torno de 50 a 75 litros. Relativamente ao moi-preço, a informação reunida indica um valor entre 25 e 55 litros de cereal, Torna-se, assim, evidente, que o moio-preço não era equivalente ao moio-medida comum, podendo, no entanto, ser equivalente aos moios menores que ainda sobreviviam nas áreas rurais.

Full Text Available The Waardenburg syndrome was first clearly defined in 1951. The major clinical importance lies in the fact that about 20% of affected individuals are deaf. Furthermore, because the condition is inherited autosomal dominantly, there is a risk of the disorder being handed down from generation to generation. The syndrome consists of six major features which may appear in any combination and to any degree in the affected individual.

Autistic spectrum disorders (ASDs) are a family of neurodevelopmental disorders with strong genetic components. Recent studies have shown that copy number variations in dosage sensitive genes can contribute significantly to these disorders. One such gene is the transcription factor MECP2, whose loss of function in females results in Rett syndrome, while its duplication in males results in developmental delay and autism. Here, we identified a Chinese family with two brothers both inheriting a 2.2 Mb MECP2-containing duplication (151,369,305 - 153,589,577) from their mother. In addition, both brothers also had a 213.7 kb duplication on Chromosome 2, inherited from their father. The older brother also carried a 48.4 kb duplication on Chromosome 2 inherited from the mother, and a 8.2 kb deletion at 11q13.5 inherited from the father. Based on the published literature, MECP2 is the most autism-associated gene among the identified CNVs. Consistently, the boys displayed clinical features in common with other patients carrying MECP2 duplications, including intellectual disability, autism, lack of speech, slight hypotonia and unsteadiness of movement. They also had slight dysmorphic features including a depressed nose bridge, large ears and midface hypoplasia. Interestingly, they did not exhibit other clinical features commonly observed in American-European patients with MECP2 duplication, including recurrent respiratory infections and epilepsy. To our knowledge, this is the first identification and characterization of Chinese Han patients with MECP2-containing duplications. Further cases are required to determine if the above described clinical differences are due to individual variations or related to the genetic background of the patients.

Mitochondrial DNA paradox: sex-specific genetic structure in a marine mussel – despite maternal inheritance and passive dispersal

Directory of Open Access Journals (Sweden)

Teske Peter R

2012-06-01

Full Text Available Abstract Background When genetic structure is identified using mitochondrial DNA (mtDNA, but no structure is identified using biparentally-inherited nuclear DNA, the discordance is often attributed to differences in dispersal potential between the sexes. Results We sampled the intertidal rocky shore mussel Perna perna in a South African bay and along the nearby open coast, and sequenced maternally-inherited mtDNA (there is no evidence for paternally-inherited mtDNA in this species and a biparentally-inherited marker. By treating males and females as different populations, we identified significant genetic structure on the basis of mtDNA data in the females only. Conclusions This is the first study to report sex-specific differences in genetic structure based on matrilineally-inherited mtDNA in a passively dispersing species that lacks social structure or sexual dimorphism. The observed pattern most likely stems from females being more vulnerable to selection in habitats from which they did not originate, which also manifests itself in a male-biased sex ratio. Our results have three important implications for the interpretation of population genetic data. First, even when mtDNA is inherited exclusively in the female line, it also contains information about males. For that reason, using it to identify sex-specific differences in genetic structure by contrasting it with biparentally-inherited markers is problematic. Second, the fact that sex-specific differences were found in a passively dispersing species in which sex-biased dispersal is unlikely highlights the fact that significant genetic structure is not necessarily a function of low dispersal potential or physical barriers. Third, even though mtDNA is typically used to study historical demographic processes, it also contains information about contemporary processes. Higher survival rates of males in non-native habitats can erase the genetic structure present in their mothers within a single

Colorectal cancer (CRC) is the fourth most common cancer in the world and is classified according to their origin in sporadic CRC (~ 70%) and genetic CRC (~ 30%), this latter involves cases of familial aggregation and inherited síndromes that predispose to CRC. To describe inherited CRC predisposition syndromes, polyposic and non-polyposic, identified in the Oncogenetics Unit at National Institute of Cancer Disease (INEN). A descriptive observational record from the attentions of the Oncogenetics Unit at INEN during 2009 to 2013. We included patients with personal or familiar history of CRC and/or colonic polyposis who were referred for clinical assessment to the Oncogenetics Unitat INEN. 59.3 % were female, 40.7 % male, 69.8% under 50 years old, 60.5% had a single CRC, 23.2% had more than one CRC or CRC associated with other extracolonic neoplasia and 32.6% had a familiar history of cancer with autosomal dominant inheritance. According to the clinical genetic diagnosis, 93.1% of the included cases were inherited syndromes that predispose to CRC, with 33.8% of colonic polyposis syndromes, 23.3% of hereditary nonpolyposis CRC syndromes (HNPCC) and 36.0% of CCRHNP probable cases. Clinical genetic evaluation of patients with personal or familiar history of CRC and/or colonic polyposis can identify inherited colorectal cancer predisposition syndromes and provide an appropriategenetic counseling to patients and relatives at risk, establishing guidelines to follow-up and prevention strategies to prevent morbidity and mortality by cancer.

To determine the latent effect of diabetes inheritance on central nervous system, thirty diabetic patients were examined (14 male, 16 female). Seventeen patients had a mother with diabetes, and the other thirteen had non-diabetic mothers. They were previously determined to not have the 3243 mitochondrial tRNA mutation in peripheral leukocytes. Patients were tested for parieto-occipital hypoaccumulation of 123 I-IMP of brain SPECT, a characteristic neurofinding of mitochondrial diabetes mellitus due to the 3243 tRNA mutation. Seven (41.2%) out of 17 subjects with material inheritance had the parieto-occipital abnormality, whereas one (7.7%) out of 13 subjects with non-maternal inheritance had the abnormality. Seventeen (94.4%) out of 18 patients diabetes due to mitochondrial tRNA mutation at position 3243 showed the abnormality. Our results suggest that the material inheritance of diabetes is associated with the hypoaccumulation of 123 I-IMP of brain SPECT. We speculate that, because the patients with maternal inheritance might have subclinical mitochondrial dysfunction due to unknown mitochondrial DNA abnormalities, the mitochondrial DNA abnormality might cause their subclinical brain damage in the parieto-occipital area.

Full Text Available The power of women, in particular the power of queens, has been a topic of great interest to historians, medievalists in particular; though much has been written about the subject, many questions remain. “Three Violantes” will look at the role of two Iberian queens and one Spanish princess in the thirteenth century Iberian kingdoms. In England and in other European kingdoms of that time, queens had lost authority and their agency was limited to the power of intercession and mediation, I will try to determine whether this also holds true for the Iberian queens.El interés por el tema del poder de las mujeres, en particular de las reinas, ha planteado muchos interrogantes sobre la naturaleza de ese poder. “Tres Violantes” examina la participación de dos reinas y una infanta de una misma familia, en aspectos diversos de la vida de las coronas de Aragón y Castilla en el siglo XIII, con el objetivo de apreciar si el papel de las reinas hispanas, en particular su participación política, siguió un camino similar al de las reinas de ese tiempo que, como bien se ha estudiado para las inglesas, fueron perdiendo autoridad y se vieron limitadas a ejercer poder a través de la intercesión y mediación.

The inherited basis of human radiosensitivity

2001-01-01

Certain individuals cannot tolerate 'conventional' doses of radiation therapy. This is known to be true of patients with ataxia-telangiectasia and ligase IV deficiency. Although in vitro testing may not correlate completely with clinical radiosensitivity, fibroblasts and lymphoblasts from patients with both of these disorders have been clearly shown to be radiosensitive. Using a colony survival assay (CSA) to test lymphoblastoid cells after irradiation with 1 Gy, a variety of other genetic disorders have been identified as strong candidates for clinical radiosensitivity, such as Nijmegen breakage syndrome, Mre11 deficiency, and Fanconi's anemia. These data are presented and considered as a starting-point for the inherited basis of human radiosensitivity

Inheritance of p,p'-DDE phytoextraction ability in hybridized Cucurbita pepo cultivars.

White, Jason C

2010-07-01

Cucurbita pepo ssp pepo (zucchini) has been shown to uniquely phytoextract percent level amounts of dichlorodiphenyldichloroethylene (DDE) and other organic contaminants from soil. Since C. pepo ssp ovifera (squash) does not have this ability, a three-year field trial was conducted to follow the inheritance pattern of DDE accumulation for cross pollinated C. pepo cultivars. Parental zucchini and squash cultivars (3 each) had stem-to-soil bioconcentration factors (BCF, contaminant ratio of stem to soil) of 16 and 1.7, respectively, and phytoextracted 1.8 and 0.18% of the DDE from soil. The 18 possible first filial (F1) hybrids of zucchini and squash accumulated significantly different DDE levels than the respective parents. The zucchini F1 hybrid (zucchini pollinated with squash) stem BCFs and percent phytoextraction values were 10 and 0.96, respectively, or 36% and 47% less than the parental zucchini. The squash F1 hybrid (squash pollinated with zucchini) stem BCFs and percent phytoextraction values were 8.3 and 0.68, respectively, or 490% and 370% greater than the parental squash. When backcrossed (BC) with the original parent, the nine zucchini F1 BC cultivars did not regain the capability to take up DDE; stem BCFs and percent phytoextraction values were equivalent to those of the F1 generation. However, the nine squash F1 BC cultivars lost much of the DDE uptake capability of the F1 generation; stem BCFs and percent phytoextraction values were intermediate but closer to those of the parental squash.

The inheritance patterns of asymmetry in mouth opening in zebrafish were investigated using crossing experiments. Zebrafish exhibit asymmetric laterality in mouth opening, with each individual having either a leftward (righty) or rightward (lefty) bias. All righty incrosses produced only righty F(1), whereas all lefty incrosses resulted in an F(1) L:R ratio of 2:1. All test crosses between lefty and righty individuals resulted in an F(1) L:R=1:1. These results were consistent with the hereditary pattern for Japanese medaka, three Tanganyikan cichlids, and a Japanese riverine goby. The pattern suggests a one-locus two-allele Mendelian model of inheritance, with the lefty allele being dominant over righty and the dominant homozygote being lethal. To determine the reason for the absence of lefty homozygotes, the survival rates of the offspring were examined according to developmental stage. Survival did not differ among combinations of parent laterality. Thus the mechanism underlying the lethality of the dominant homozygote remains unclear. This study showed that the mouth-opening laterality of zebrafish is genetically determined and that the direction follows a Mendelian inheritance pattern that is shared among cypriniform zebrafish, beloniform medaka, perciform cichlids, and a goby, suggesting a common genetic background in mouth-opening laterality among these species.

To analyze the composition and medication regularities of prescriptions treating hypochondriac pain in Chinese journal full-text database (CNKI) based on the traditional Chinese medicine inheritance support system, in order to provide a reference for further research and development for new traditional Chinese medicines treating hypochondriac pain. The traditional Chinese medicine inheritance support platform software V2. 0 was used to build a prescription database of Chinese medicines treating hypochondriac pain. The software integration data mining method was used to distribute prescriptions according to "four odors", "five flavors" and "meridians" in the database and achieve frequency statistics, syndrome distribution, prescription regularity and new prescription analysis. An analysis were made for 192 prescriptions treating hypochondriac pain to determine the frequencies of medicines in prescriptions, commonly used medicine pairs and combinations and summarize 15 new prescriptions. This study indicated that the prescriptions treating hypochondriac pain in Chinese journal full-text database are mostly those for soothing liver-qi stagnation, promoting qi and activating blood, clearing heat and promoting dampness, and invigorating spleen and removing phlem, with a cold property and bitter taste, and reflect the principles of "distinguish deficiency and excess and relieving pain by smoothening meridians" in treating hypochondriac pain.

Local structure inheritance signatures were observed during the alloying process of the Ag 50 Sn 50 melt, using high-temperature X-ray diffraction and ab initio molecular dynamics simulations. The coordination number N m around Ag atom is similar in the alloy and in pure Ag melts (N m  ∼ 10), while, during the alloying process, the local structure around Sn atoms rearranges. Sn-Sn covalent bonds were substituted by Ag-Sn chemical bonds, and the total coordination number around Sn increases by about 70% as compared with those in the pure Sn melt. Changes in the electronic structure of the alloy have been studied by Ag and Sn K-edge X-ray absorption spectroscopy, as well as by calculations of the partial density of states. We propose that a leading mechanism for local structure inheritance in Ag 50 Sn 50 is due to s-p dehybridization of Sn and to the interplay between Sn-s and Ag-d electrons

Factor VII (FVII) deficiency is one of the rare inherited bleeding disorders. Thrombosis has been occasionally described in inherited FVII deficiency. Here, we report a young female with undiagnosed FVII deficiency who presented with cerebral venous sinus thrombosis (CVST). Oral contraceptive pill was found to be prothrombotic risk factor. The CVSToccurred in spite of the congenital FVII deficiency indicating that no definitive antithrombotic protection is assured by this defect. Low molecular weight heparin and anti-Xa assay were found to be safe choice of anticoagulation and monitoring, respectively, in this patient.

Bisphenol A (BPA) is an endocrine disruptor used in manufacturing of plastic devices, resulting in an ubiquitous presence in the environment linked to human infertility, obesity or cardiovascular diseases. Both transcriptome and epigenome modifications lie behind these disorders that might be inherited transgenerationally when affecting germline. To assess potential effects of paternal exposure on offspring development, adult zebrafish males were exposed to BPA during spermatogenesis and mated with non-treated females. Results showed an increase in the rate of heart failures of progeny up to the F2, as well as downregulation of 5 genes involved in cardiac development in F1 embryos. Moreover, BPA causes a decrease in F0 and F1 sperm remnant mRNAs related to early development. Results reveal a paternal inheritance of changes in the insulin signaling pathway due to downregulation of insulin receptor β mRNAs, suggesting a link between BPA male exposure and disruption of cardiogenesis in forthcoming generations. - Highlights: • We examine the effects of adult male exposure to BPA on the progeny (F1 and F2). • Paternal exposure promotes similar cardiac malformations to those caused by direct exposure. • BPA applied during spermatogenesis decrease the insra and insrb transcripts in spermatozoa. • Sperm insrb transcript controls embryonic expression being the downregulation inherited by F1. • Paternal BPA exposure impairs heart development in F1 and F2 disrupting insulin signaling pathway. - Paternal bisphenol A exposure impairs cardiac development throughout generations.

Full Text Available Abstract Background Since S. cerevisiae undergoes closed mitosis, the nuclear envelope of the daughter nucleus is continuous with that of the maternal nucleus at anaphase. Nevertheless, several constitutents of the maternal nucleus are not present in the daughter nucleus. The present study aims to identify proteins which impact the shape of the yeast nucleus and to learn whether modifications of shape are passed on to the next mitotic generation. The Esc1p protein of S. cerevisiae localizes to the periphery of the nucleoplasm, can anchor chromatin, and has been implicated in targeted silencing both at telomeres and at HMR. Results Upon increased Esc1p expression, cell division continues and dramatic elaborations of the nuclear envelope extend into the cytoplasm. These "escapades" include nuclear pores and associate with the nucleolus, but exclude chromatin. Escapades are not inherited by daughter nuclei. This exclusion reflects their relative immobility, which we document in studies of prezygotes. Moreover, excess Esc1p affects the levels of multiple transcripts, not all of which originate at telomere-proximal loci. Unlike Esc1p and the colocalizing protein, Mlp1p, overexpression of selected proteins of the inner nuclear membrane is toxic. Conclusion Esc1p is the first non-membrane protein of the nuclear periphery which – like proteins of the nuclear lamina of higher eukaryotes – can modify the shape of the yeast nucleus. The elaborations of the nuclear envelope ("escapades" which appear upon induction of excess Esc1p are not inherited during mitotic growth. The lack of inheritance of such components could help sustain cell growth when parental nuclei have acquired potentially deleterious characteristics.

2008-01-01

Full Text Available Caffeine inheritance was investigated in F2 and BC1F1 generations between Coffea arabica var. Bourbon Vermelho (BV and Coffea canephora var. Robusta 4x (R4x. The caffeine content of seeds and leaves was determined during 2004 and 2005. Microsatellite loci-markers were used to deduce the meiotic pattern of chromosome pairing of tetraploid interspecific hybrids. Genetic analysis indicated that caffeine content in seeds was quantitatively inherited and controlled by genes with additive effects. The estimates of broad-sense heritability of caffeine content in seeds were high for both generations. In coffee leaves, the caffeine content (BSH from the same populations showed transgressive segregants with enhanced levels and high BSH. Segregation of loci-markers in BC1F1 populations showed that the ratios of the gametes genotype did not differ significantly from those expected assuming random associations and tetrasomic inheritance. The results confirm the existence of distinct mechanisms controlling the caffeine content in seeds and leaves, the gene exchange between the C. arabica BV and C. canephora R4x genomes and favorable conditions for improving caffeine content in this coffee population.

Full Text Available Environmental compounds can promote epigenetic transgenerational inheritance of adult-onset disease in subsequent generations following ancestral exposure during fetal gonadal sex determination. The current study examined the ability of dioxin (2,3,7,8-tetrachlorodibenzo[p]dioxin, TCDD to promote epigenetic transgenerational inheritance of disease and DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to dioxin during fetal day 8 to 14 and adult-onset disease was evaluated in F1 and F3 generation rats. The incidences of total disease and multiple disease increased in F1 and F3 generations. Prostate disease, ovarian primordial follicle loss and polycystic ovary disease were increased in F1 generation dioxin lineage. Kidney disease in males, pubertal abnormalities in females, ovarian primordial follicle loss and polycystic ovary disease were increased in F3 generation dioxin lineage animals. Analysis of the F3 generation sperm epigenome identified 50 differentially DNA methylated regions (DMR in gene promoters. These DMR provide potential epigenetic biomarkers for transgenerational disease and ancestral environmental exposures. Observations demonstrate dioxin exposure of a gestating female promotes epigenetic transgenerational inheritance of adult onset disease and sperm epimutations.

Role of TGF-β signaling in inherited and acquired myopathies

2011-05-01

Full Text Available Abstract The transforming growth factor-beta (TGF-β superfamily consists of a variety of cytokines expressed in many different cell types including skeletal muscle. Members of this superfamily that are of particular importance in skeletal muscle are TGF-β1, mitogen-activated protein kinases (MAPKs, and myostatin. These signaling molecules play important roles in skeletal muscle homeostasis and in a variety of inherited and acquired neuromuscular disorders. Expression of these molecules is linked to normal processes in skeletal muscle such as growth, differentiation, regeneration, and stress response. However, chronic elevation of TGF-β1, MAPKs, and myostatin is linked to various features of muscle pathology, including impaired regeneration and atrophy. In this review, we focus on the aberrant signaling of TGF-β in various disorders such as Marfan syndrome, muscular dystrophies, sarcopenia, and critical illness myopathy. We also discuss how the inhibition of several members of the TGF-β signaling pathway has been implicated in ameliorating disease phenotypes, opening up novel therapeutic avenues for a large group of neuromuscular disorders.

Property Rights, Inheritance by Wives and Gender Equality: Brazil and Hispanic America in Comparative Perspective

Directory of Open Access Journals (Sweden)

Carmen Diana Derre

2001-01-01

Full Text Available Considerable gains were made in Latin America over the course of the twentieth century in strengthening the property rights of married women. Insufficient attention, nonetheless, has been given to the inheritance rights of wives. Reviewing the legal norms for twelve countries, it is argued that widows are often in a disadvantaged position compared to the children of a couple. Inheritance norms were not designed to give widows the possibility for economic autonomy, such as through control of the family farm or business. Moreover, given the gender gap favoring women in the lengthening of life spans and the low coverage of social security (particularly in rural areas in most countries, they are particularly vulnerable when they are widowed. The women’s movement is urged to take on the issue of inheritance rights since strengthening these are necessary to achieve a redistribution of property and real gender equality.

From 1974 to 1976, a breeding program was used to produce hybrids of black ducks and mallards for the evaluation of inheritance patterns of serum proteins and serum, liver and muscle enzymes. In addition to the crosses designed to produce hybrids, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns of a hybrid with either a black duck or mallard. At the F1 level, hybrids were easily distinguished using serum proteins. However, once a hybrid was crossed back to either a mallard or black duck, only 12?23% of the progeny were distinguishable from black ducks or mallards using serum proteins and 23?39% using esterases. Muscle, serum and liver enzymes were similar between the two species.

Homens de leis e homens de letras serviram à casa real como oficiais, representaram os reis portugueses em atos políticos e diplomáticos e exerceram um grande leque de funções na esfera da administração central - políticas, jurídicas, médicas, económicas, administrativas. A presença desses elementos ao lado dos monarcas fez-se sentir desde a fundação do reino, logo desde o reinado de D. Afonso Henriques, coincidindo o corolário deste processo de recrutamento com a chegada de D. Afonso III ao trono, numa política continuada, de forma firme, por D. Dinis. O conjunto de eruditos recenseados junto dos reis portugueses da época fundacional constitui, nessa medida, um interessante estudo de caso para compreender, em parte, em que consistia um círculo áulico, à luz dos valores do século XII e XIII.

Full Text Available Abstract Background Autistic spectrum disorders (ASDs are a family of neurodevelopmental disorders with strong genetic components. Recent studies have shown that copy number variations in dosage sensitive genes can contribute significantly to these disorders. One such gene is the transcription factor MECP2, whose loss of function in females results in Rett syndrome, while its duplication in males results in developmental delay and autism. Case presentation Here, we identified a Chinese family with two brothers both inheriting a 2.2 Mb MECP2-containing duplication (151,369,305 – 153,589,577 from their mother. In addition, both brothers also had a 213.7 kb duplication on Chromosome 2, inherited from their father. The older brother also carried a 48.4 kb duplication on Chromosome 2 inherited from the mother, and a 8.2 kb deletion at 11q13.5 inherited from the father. Based on the published literature, MECP2 is the most autism-associated gene among the identified CNVs. Consistently, the boys displayed clinical features in common with other patients carrying MECP2 duplications, including intellectual disability, autism, lack of speech, slight hypotonia and unsteadiness of movement. They also had slight dysmorphic features including a depressed nose bridge, large ears and midface hypoplasia. Interestingly, they did not exhibit other clinical features commonly observed in American-European patients with MECP2 duplication, including recurrent respiratory infections and epilepsy. Conclusions To our knowledge, this is the first identification and characterization of Chinese Han patients with MECP2-containing duplications. Further cases are required to determine if the above described clinical differences are due to individual variations or related to the genetic background of the patients.

Certain individuals cannot tolerate 'conventional' doses of radiation therapy. This is known to be true of patients with ataxia-telangiectasia and ligase IV deficiency. Although in vitro testing may not correlate completely with clinical radiosensitivity, fibroblasts and lymphoblasts from patients with both of these disorders have been clearly shown to be radiosensitive. Using a colony survival assay (CSA) to test lymphoblastoid cells after irradiation with 1 Gy, a variety of other genetic disorders have been identified as strong candidates for clinical radiosensitivity, such as Nijmegen breakage syndrome, Mre11 deficiency, and Fanconi's anemia. These data are presented and considered as a starting-point for the inherited basis of human radiosensitivity.

We assessed the resemblance of lip print patterns between parents and biological offspring in families of 31 Malay students as well as the distribution of different types of lip print in the study group. Only a few studies have successfully established the inheritance pattern of lip prints. Such studies can be population specific and need to be conducted in various populations. No such study have been conducted in Malay population in Malaysia, according to our knowledge. Present study was carried out to ascertain whether there is any inherence pattern in lip prints and thereby to investigate the potential role of lip prints in personal identification. We found 58.06% resemblance of lip print patterns between the parents and their biological offspring in our study. The influence of heredity in lip print pattern is still a new concept and there is lack of concrete evidence. The data from our study shows that there is potential influence of inheritance in the lip print patterns among the family members. Further researches involving larger samples size are suggested to derive more reliable and accurate results. The most common lip print pattern among the study group is type I (29.84%) followed by type II (23.12%), type III (22.45%), type I' (13.44%), type IV (9.54%) and type V (1.61%). Racial variations in lip print patterns and their prevalence may serve as an aid in forensic identification and crime scene investigation. The results of this pilot study will help in establishing guidelines for future researches on lip print analysis in Malaysia. Lip print patterns are unique and individualistic. However, there are some similarities in basic patterns of lip prints between family members which may be attributed to influence of inheritance. 1.

The customs of widow cleansing and widow inheritance are practiced in several communities throughout sub-Saharan Africa. In the Nyanza Province of Kenya, according to tradition, Luo widows are expected to engage in sexual intercourse with a "cleanser," without the use of a condom, in order to remove the impurity ascribed to her after her husband's death. Luo couples, including widows, are also expected to engage in sex preceding specific agricultural activities, building homes, funerals, weddings, and other significant cultural and social events. Widows who are inherited for the purpose of fulfilling cultural obligation have a higher prevalence of HIV than those who remain un-inherited or are inherited for the purpose of companionship. As part of a larger descriptive qualitative study to inform study procedures for FEM-PrEP, an HIV prevention pre-exposure prophylaxis clinical trial, we conducted 15 semi-structured interviews (SSIs) with widows, 15 SSIs with inheritors, and four focus group discussions with widows in the Bondo and Rarieda districts in Nyanza Province to explore the HIV risk context within widow cleansing and inheritance practices. Thematic qualitative analysis was used to analyze the data. The majority of widows reported in the demographic questionnaire being inherited, and most widows in the SSIs described participating in the cleansing ritual. We identified two main themes related to HIV prevention within the context of widow cleansing and inheritance: 1) widows must balance limiting their risk for HIV infection with meeting cultural expectations and ensuring that their livelihood needs are met, and 2) sexual abstinence undermines cultural expectations in widowhood while the use of condoms is deemed inappropriate in fulfilling culturally prescribed sexual rituals, and is often beyond the widow's ability to negotiate. Women-controlled HIV prevention methods such as antiretroviral-based oral pre-exposure prophylaxis, vaginal gels, and vaginal rings

To determine the latent effect of diabetes inheritance on central nervous system, thirty diabetic patients were examined (14 male, 16 female). Seventeen patients had a mother with diabetes, and the other thirteen had non-diabetic mothers. They were previously determined to not have the 3243 mitochondrial tRNA mutation in peripheral leukocytes. Patients were tested for parieto-occipital hypoaccumulation of {sup 123}I-IMP of brain SPECT, a characteristic neurofinding of mitochondrial diabetes mellitus due to the 3243 tRNA mutation. Seven (41.2%) out of 17 subjects with material inheritance had the parieto-occipital abnormality, whereas one (7.7%) out of 13 subjects with non-maternal inheritance had the abnormality. Seventeen (94.4%) out of 18 patients diabetes due to mitochondrial tRNA mutation at position 3243 showed the abnormality. Our results suggest that the material inheritance of diabetes is associated with the hypoaccumulation of {sup 123}I-IMP of brain SPECT. We speculate that, because the patients with maternal inheritance might have subclinical mitochondrial dysfunction due to unknown mitochondrial DNA abnormalities, the mitochondrial DNA abnormality might cause their subclinical brain damage in the parieto-occipital area.

Summary Tuberculosis (TB), caused by Mycobacterium tuberculosis (M.tb) and a few related mycobacteria, is a devastating disease, killing more than a million individuals per year worldwide. However, its pathogenesis remains largely elusive, as only a small proportion of infected individuals develop clinical disease either during primary infection or during reactivation from latency or secondary infection. Subacute, hematogenous, and extrapulmonary disease tends to be more frequent in infants, children, and teenagers than in adults. Life-threatening primary TB of childhood can result from known acquired or inherited immunodeficiencies, although the vast majority of cases remain unexplained. We review here the conditions conferring a predisposition to childhood clinical diseases caused by mycobacteria, including not only M.tb but also weakly virulent mycobacteria, such as BCG vaccines and environmental mycobacteria. Infections with weakly virulent mycobacteria are much rarer than TB, but the inherited and acquired immunodeficiencies underlying these infections are much better known. Their study has also provided genetic and immunological insights into childhood TB, as illustrated by the discovery of single-gene inborn errors of IFN-γ immunity underlying severe cases of TB. Novel findings are expected from ongoing and future human genetic studies of childhood TB in countries that combine a high proportion of consanguineous marriages, a high incidence of TB, and an excellent clinical care, such as Iran, Morocco, and Turkey.

ABSTRACT The genetic inheritance of resistance to leprosis, the most important viral disease of citrus in Brazil, was characterized through the phenotypic assessment of 143 hybrids resulting from crosses between tangor 'Murcott' (Citrus sinensis x C. reticulata) and sweet orange 'Pêra' (C. sinensis), considered to be resistant and susceptible to the disease, respectively. All plants were grafted onto Rangpur lime (C. limonia) and inoculated with Citrus leprosis virus, cytoplasmic type through the infestation with viruliferous mites, Brevipalpus phoenicis. The experiments were arranged in a completely randomized block design with 10 replicates. Incidence and severity of the disease in leaves and stems as well as plant growth parameters (plant height and stem diameter) were recorded for 3 years after the infestation with the viruliferous mites. The average values of all variables were analyzed using principal component analysis, discriminant factorial analysis, estimation of the clonal repeatability coefficients, and frequency of the distributions of the average values for each measured variable. The principal component analysis resulted in the identification of at least two groups with resistance and susceptibility to leprosis, respectively. About 99% of all hybrids were correctly classified according to the discriminant factorial analysis. The broad-sense heritability coefficients for characteristics associated with incidence and severity of leprosis ranged from 0.88 to 0.96. The data suggest that the inheritance of resistance to leprosis may be controlled by only a few genes.

Fatty liver is a widespread disease in chickens that causes a decrease in egg production and even death. The characteristics of the inherited phenotype of acquired fatty liver and the molecular mechanisms underlying it, however, are largely unknown. In the current study, fatty liver was induced in 3 breeds by a high-fat (HF) diet and a methionine choline-deficient (MCD) diet. The results showed that the dwarf Jingxing-Huang (JXH) chicken was more susceptible to fatty liver compared with the layer White Leghorns (WL) and local Beijing-You (BJY) breeds. In addition, it was found that the paternal fatty livers induced by HF diet in JXH chickens were inherited. Compared to birds without fatty liver in the control group, both offsprings and their sires with fatty livers in the paternal group exhibited altered hepatic gene expression profiles, including upregulation of several key genes involved in fatty acid metabolism, lipid metabolism and glucose metabolism (ACACA, FASN, SCD, ACSL5, FADS2, FABP1, APOA4 and ME1). This study uniquely revealed that acquired fatty liver in cocks can be inherited. The hepatic gene expression profiles were altered in chickens with the inherited phenotype of acquired paternal fatty liver and several genes could be candidate biomarkers. PMID:29642504

Evolving Systems: Adaptive Key Component Control and Inheritance of Passivity and Dissipativity

Science.gov (United States)

Frost, S. A.; Balas, M. J.

2010-01-01

We propose a new framework called Evolving Systems to describe the self-assembly, or autonomous assembly, of actively controlled dynamical subsystems into an Evolved System with a higher purpose. Autonomous assembly of large, complex flexible structures in space is a target application for Evolving Systems. A critical requirement for autonomous assembling structures is that they remain stable during and after assembly. The fundamental topic of inheritance of stability, dissipativity, and passivity in Evolving Systems is the primary focus of this research. In this paper, we develop an adaptive key component controller to restore stability in Nonlinear Evolving Systems that would otherwise fail to inherit the stability traits of their components. We provide sufficient conditions for the use of this novel control method and demonstrate its use on an illustrative example.

Enduring love? Attitudes to family and inheritance law in England and Wales.

Science.gov (United States)

Douglas, Gillian; Woodward, Hilary; Humphrey, Alun; Mills, Lisa; Morrell, Gareth

2011-01-01

This paper reports on the findings from a large-scale study of public attitudes to inheritance law, particularly the rules on intestacy. It argues that far from the assumption that the family' is in terminal decline, people in England and Wales still view their most important relationships, at least for the purposes of inheritance law, as centred on a narrow, nuclear family model. However, there is also widespread acceptance of re-partnering and cohabitation, producing generally high levels of support for including cohabitants in the intestacy rules and for ensuring that children from former relationships are protected. We argue that these views are underpinned by a continuing sense of responsibility to the members of one's nuclear family, arising from notions of sharing and commitment, dependency and support, and a sense of lineage.

Inherited Disease Genetics Improves the Identification of Cancer-Associated Genes.

Full Text Available The identification of biologically significant variants in cancer genomes is critical to therapeutic discovery, but it is limited by the statistical power needed to discern driver from passenger. Independent biological data can be used to filter cancer exomes and increase statistical power. Large genetic databases for inherited diseases are uniquely suited to this task because they contain specific amino acid alterations with known pathogenicity and molecular mechanisms. However, no rigorous method to overlay this information onto the cancer exome exists. Here, we present a computational methodology that overlays any variant database onto the somatic mutations in all cancer exomes. We validate the computation experimentally and identify novel associations in a re-analysis of 7362 cancer exomes. This analysis identified activating SOS1 mutations associated with Noonan syndrome as significantly altered in melanoma and the first kinase-activating mutations in ACVR1 associated with adult tumors. Beyond a filter, significant variants found in both rare cancers and rare inherited diseases increase the unmet medical need for therapeutics that target these variants and may bootstrap drug discovery efforts in orphan indications.

Anorectal malformations (ARM) are rare abnormalities that occur in approximately 1 in 3000 live births with around 40% of patients presenting with isolated forms. Multiple familial cases reported, suggest underlying genetic factors that remain largely unknown. The recurrence in relatives is considered rare, however transmission rates of ARM by affected parents have never been determined before. The inheritance pattern of ARM was investigated in our database of patients with isolated ARM. Within our cohort of 327 patients with isolated ARM we identified eight adult patients from eight families who had in total 16 children with their healthy spouse. Of these ten had ARM, resulting in a recurrence risk of approximately one in two live births (10 of 16; 62%). From 226 families with 459 siblings we found two affected siblings in five families. Hence, the recurrence risk of ARM among siblings is approximately one in 92 live births (5 of 459; 1.0%). Comparing the observed recurrence risk in our cohort with the prevalence in the general population, we see a 1500-fold increase in recurrence risk for offspring and a 32-fold increase if a sibling is affected. The recurrence risk of approximately 62% indicates an autosomal dominant mode of inheritance. Reliable figures on recurrence of ARM are becoming increasingly important since improved surgical techniques are able to maintain sexual function resulting in more offspring of patients with ARM. These data allow more precise counseling of families with ARM and support the need for genetic studies.

Developmental malformations of the vitreoretinal vasculature are a heterogeneous group of conditions with various modes of inheritance, and include familial exudative vitreoretinopathy (FEVR), persistent fetal vasculature (PFV), and Norrie disease. We investigated a large consanguineous kindred with multiple affected individuals exhibiting variable phenotypes of abnormal vitreoretinal vasculature, consistent with the three above-mentioned conditions and compatible with autosomal recessive inheritance. Exome sequencing identified a novel c.542G > T (p.C181F) apparently mutation in the TSPAN12 gene that segregated with the ocular disease in the family. The TSPAN12 gene was previously reported to cause dominant and recessive FEVR, but has not yet been associated with other vitreoretinal manifestations. The intra-familial clinical variability caused by a single mutation in the TSPAN12 gene underscores the complicated phenotype-genotype correlation of mutations in this gene, and suggests that there are additional genetic and environmental factors involved in the complex process of ocular vascularization during embryonic development. Our study supports considering PFV, FEVR, and Norrie disease a spectrum of disorders, with clinical and genetic overlap, caused by mutations in distinct genes acting in the Norrin/β-catenin signaling pathway. © 2014 Wiley Periodicals, Inc.

Full Text Available Quick and accurate molecular testing is necessary for the better management of many inherited diseases. Recent technological advances in various next generation sequencing (NGS platforms, such as target panel-based sequencing, has enabled comprehensive, quick, and precise interrogation of many genetic variations. As a result, these technologies have become a valuable tool for gene discovery and for clinical diagnostics. The AmpliSeq Inherited Disease Panel (IDP consists of 328 genes underlying more than 700 inherited diseases. Here, we aimed to assess the performance of the IDP as a sensitive and rapid comprehensive gene panel testing. A total of 88 patients with inherited diseases and causal mutations that were previously identified by Sanger sequencing were randomly selected for assessing the performance of the IDP. The IDP successfully detected 93.1% of the mutations in our validation cohort, achieving high overall gene coverage (98%. The sensitivity for detecting single nucleotide variants (SNVs and short Indels was 97.3% and 69.2%, respectively. IDP, when coupled with Ion Torrent Personal Genome Machine (PGM, delivers comprehensive and rapid sequencing for genes that are responsible for various inherited diseases. Our validation results suggest the suitability of this panel for use as a first-line screening test after applying the necessary clinical validation.

Studies of the role of the early environment in shaping children’s risk for anxiety problems have produced mixed results. It is possible that inconsistencies in previous findings result from a lack of consideration of a putative role for inherited influences moderators on the impact of early experiences. Early inherited influences not only contribute to vulnerabilities for anxiety problems throughout the lifespan, but can also modulate the ways that the early environment impacts child outcomes. In the current study, we tested the effects of child-centered parenting behaviors on putative anxiety risk in young children who differed in levels of inherited vulnerability. We tested this using a parent-offspring adoption design and a sample in which risk for anxiety problems and parenting behaviors were assessed in both mothers and fathers. Inherited influences on anxiety problems were assessed as anxiety symptoms in biological parents. Child-centered parenting was observed in adoptive mothers and fathers when children were 9 months old. Social inhibition, an early temperament marker of anxiety risk, was observed at child ages 9 and 18 months. Inherited influences on anxiety problems moderated the link between paternal child-centered parenting during infancy and social inhibition in toddlerhood. For children whose birth parents reported high levels of anxiety symptoms, greater child-centered parenting in adoptive fathers was related to greater social inhibition 9 months later. For children whose birth parents reported low levels of anxiety symptoms, greater child-centered parenting in adoptive fathers was related to less social inhibition across the same period.

Full Text Available Bartter′s and Gitelman′s syndrome are two ends of a spectrum of inherited renal tubular disorders that present with hypokalemic metabolic alkalosis of varying severity. Clinical features and associated calcium and magnesium ion abnormalities are used to diagnose these cases after excluding other commoner causes. We report on two cases, the first being a young boy, born of pregnancy complicated by polyhydramnios, who had classical dysmorphic features, polyuria, hypokalemia and hypercalciuria and was diagnosed as having Bartter′s syndrome. The second patient is a lady who had recurrent tetany as the only manifestation of Gitelman′s syndrome, which is an unusual presentation. Potassium replacement with supplementation of other deficient ions led to satisfactory clinical and biochemical response.

Cultivated chrysanthemum is an outcrossing hexaploid (2n = 6× = 54) with a disputed mode of inheritance. In this paper, we present a single nucleotide polymorphism (SNP) selection pipeline that was used to design an Affymetrix Axiom array with 183 k SNPs from RNA sequencing data (1). With this array, we genotyped four bi-parental populations (with sizes of 405, 53, 76 and 37 offspring plants respectively), and a cultivar panel of 63 genotypes. Further, we present a method for dosage scoring in hexaploids from signal intensities of the array based on mixture models (2) and validation of selection steps in the SNP selection pipeline (3). The resulting genotypic data is used to draw conclusions on the mode of inheritance in chrysanthemum (4), and to make an inference on allelic expression bias (5). With use of the mixture model approach, we successfully called the dosage of 73,936 out of 183,130 SNPs (40.4%) that segregated in any of the bi-parental populations. To investigate the mode of inheritance, we analysed markers that segregated in the large bi-parental population (n = 405). Analysis of segregation of duplex x nulliplex SNPs resulted in evidence for genome-wide hexasomic inheritance. This evidence was substantiated by the absence of strong linkage between markers in repulsion, which indicated absence of full disomic inheritance. We present the success rate of SNP discovery out of RNA sequencing data as affected by different selection steps, among which SNP coverage over genotypes and use of different types of sequence read mapping software. Genomic dosage highly correlated with relative allele coverage from the RNA sequencing data, indicating that most alleles are expressed according to their genomic dosage. The large population, genotyped with a very large number of markers, is a unique framework for extensive genetic analyses in hexaploid chrysanthemum. As starting point, we show conclusive evidence for genome-wide hexasomic inheritance.

Sex-biased gene flow in spectacled eiders (Anatidae): Inferences from molecular markers with contrasting modes of inheritance

2001-01-01

Genetic markers that differ in mode of inheritance and rate of evolution (a sex-linked Z-specific microsatellite locus, five biparentally inherited microsatellite loci, and maternally inherited mitochondrial [mtDNA] sequences) were used to evaluate the degree of spatial genetic structuring at macro- and microgeographic scales, among breeding regions and local nesting populations within each region, respectively, for a migratory sea duck species, the spectacled eider (Somateria fisheri). Disjunct and declining breeding populations coupled with sex-specific differences in seasonal migratory patterns and life history provide a series of hypotheses regarding rates and directionality of gene flow among breeding populations from the Indigirka River Delta, Russia, and the North Slope and Yukon-Kuskokwim Delta, Alaska. The degree of differentiation in mtDNA haplotype frequency among breeding regions and populations within regions was high (ϕCT = 0.189, P 0.05; biparentally inherited microsatellites: mean θ = 0.001, P > 0.05) than was observed for mtDNA. Using models explicitly designed for uniparental and biparentally inherited genes, estimates of spatial divergence based on nuclear and mtDNA data together with elements of the species' breeding ecology were used to estimate effective population size and degree of male and female gene flow. Differences in the magnitude and spatial patterns of gene correlations for maternally inherited and nuclear genes revealed that females exhibit greater natal philopatry than do males. Estimates of generational female and male rates of gene flow among breeding regions differed markedly (3.67 × 10−4 and 1.28 × 10−2, respectively). Effective population size for mtDNA was estimated to be at least three times lower than that for biparental genes (30,671 and 101,528, respectively). Large disparities in population sizes among breeding areas greatly reduces the proportion of total genetic variance captured by dispersal, which may

Full Text Available Inherited and autoimmune blistering diseases are rare, chronic, and often severe disorders that have the potential to significantly affect patients’ quality of life. The effective management of these conditions requires consideration of the physical, emotional, and social aspects of the disease. Self-esteem is integral to patients’ ability to cope with their illness, participate in treatment, and function in society. This article discusses quality-of-life studies of patients with blistering diseases with a particular focus on self-esteem issues that patients may face.

Psychiatric symptoms often manifest years before overt neurologic signs in patients with inherited neurodegenerative disease. The most frequently cited example of this phenomenon is the early onset of personality changes in "presymptomatic" Huntington patients. In some cases the changes in mood and cognition are even more debilitating than their neurologic symptoms. The goal of this article is to provide the neurologist with a concise primer that can be applied in a busy clinic or private practice. Copyright © 2013 Elsevier Inc. All rights reserved.

Inheritance of the narrow leaf mutation in Pea (Pisum Sativum L.)

International Nuclear Information System (INIS)

Naidenova, N.; Vassilevska-Ivanova, R.

2006-01-01

Three pea mutant lines 2/111, 2/174 and 3/106 with reduced narrow oblong leaves were produced after gamma irradiation. They were characterized morphologically and for seed productivity elements. The size and shape of the stipules and the leaflets were evaluated by L/W (length/width) indices. Reciprocal crosses between mutants and normal plants were executed, and F1, F2 generations were analysed. It was established that mutants 2/111 and 3/106 have intermediate inheritance and they are allelic with each other; mutant 2/174 revealed single-gene recessive inheritance with deficiency of mutant plants. It was concluded that 2/174 was not allelic with 2/111 and 3/106. Mutants 2/111 and 3/106 exhibited a phenotype similar to previously described mutant fom (folium oblongum). Allelic test between the new mutants and these described previously was not performed. The reported here lines are utilized to increase understanding of the control of leaf development in pea.

Full Text Available Abstract Inherited epidermolysis bullosa (EB encompasses a number of disorders characterized by recurrent blister formation as the result of structural fragility within the skin and selected other tissues. All types and subtypes of EB are rare; the overall incidence and prevalence of the disease within the United States is approximately 19 per one million live births and 8 per one million population, respectively. Clinical manifestations range widely, from localized blistering of the hands and feet to generalized blistering of the skin and oral cavity, and injury to many internal organs. Each EB subtype is known to arise from mutations within the genes encoding for several different proteins, each of which is intimately involved in the maintenance of keratinocyte structural stability or adhesion of the keratinocyte to the underlying dermis. EB is best diagnosed and subclassified by the collective findings obtained via detailed personal and family history, in concert with the results of immunofluorescence antigenic mapping, transmission electron microscopy, and in some cases, by DNA analysis. Optimal patient management requires a multidisciplinary approach, and revolves around the protection of susceptible tissues against trauma, use of sophisticated wound care dressings, aggressive nutritional support, and early medical or surgical interventions to correct whenever possible the extracutaneous complications. Prognosis varies considerably and is based on both EB subtype and the overall health of the patient.

Pituitary stalk interruption syndrome (PSIS, ORPHA95496) is a congenital defect of the pituitary gland characterized by the triad of a very thin/interrupted pituitary stalk, an ectopic (or absent) posterior pituitary gland, and hypoplasia or aplasia of the anterior pituitary gland. Complex genetic patterns of inheritance of this disorder are increasingly recognized. The objective of this study was to identify a genetic cause of PSIS in an affected child. Whole exome sequencing (WES) was performed by using standard techniques, with prioritized genetic variants confirmed via Sanger sequencing. To investigate the effects of one candidate variant on mutant WDR11 function, Western blotting and coimmunofluorescence were used to assess binding capacity, and leptomycin B exposure along with immunofluorescence was used to assess nuclear localization. We describe a child who presented in infancy with combined pituitary hormone deficiencies and whose brain imaging demonstrated a small anterior pituitary, ectopic posterior pituitary, and a thin, interrupted stalk. WES demonstrated heterozygous missense mutations in two genes required for pituitary development, a known loss-of-function mutation in PROKR2 (c.253C>T;p.R85C) inherited from an unaffected mother, and a WDR11 (c.1306A>G;p.I436V) mutation inherited from an unaffected father. Mutant WDR11 loses its capacity to bind to its functional partner, EMX1, and to localize to the nucleus. WES in a child with PSIS and his unaffected family implicates a digenic mechanism of inheritance. In cases of hypopituitarism in which there is incomplete segregation of a monogenic genotype with the phenotype, the possibility that a second genetic locus is involved should be considered.

Genetic engineering and therapy for inherited and acquired cardiomyopathies.

Day, Sharlene; Davis, Jennifer; Westfall, Margaret; Metzger, Joseph

2006-10-01

The cardiac myofilaments consist of a highly ordered assembly of proteins that collectively generate force in a calcium-dependent manner. Defects in myofilament function and its regulation have been implicated in various forms of acquired and inherited human heart disease. For example, during cardiac ischemia, cardiac myocyte contractile performance is dramatically downregulated due in part to a reduced sensitivity of the myofilaments to calcium under acidic pH conditions. Over the last several years, the thin filament regulatory protein, troponin I, has been identified as an important mediator of this response. Mutations in troponin I and other sarcomere genes are also linked to several distinct inherited cardiomyopathic phenotypes, including hypertrophic, dilated, and restrictive cardiomyopathies. With the cardiac sarcomere emerging as a central player for such a diverse array of human heart diseases, genetic-based strategies that target the myofilament will likely have broad therapeutic potential. The development of safe vector systems for efficient gene delivery will be a critical hurdle to overcome before these types of therapies can be successfully applied. Nonetheless, studies focusing on the principles of acute genetic engineering of the sarcomere hold value as they lay the essential foundation on which to build potential gene-based therapies for heart disease.

A general problem is posed by analysis of transcriptional thresholds governing cell fate decisions in metazoan development. A model is provided by testis determination in therian mammals. Its key step, Sertoli cell differentiation in the embryonic gonadal ridge, is initiated by SRY, a Y-encoded architectural transcription factor. Mutations in human SRY cause gonadal dysgenesis leading to XY female development (Swyer syndrome). Here, we have characterized an inherited mutation compatible with either male or female somatic phenotypes as observed in an XY father and XY daughter, respectively. The mutation (a crevice-forming substitution at a conserved back surface of the SRY high mobility group box) markedly destabilizes the domain but preserves specific DNA affinity and induced DNA bend angle. On transient transfection of diverse human and rodent cell lines, the variant SRY exhibited accelerated proteasomal degradation (relative to wild type) associated with increased ubiquitination; in vitro susceptibility to ubiquitin-independent ("default") cleavage by the 20S core proteasome was unchanged. The variant's gene regulatory activity (as assessed in a cellular model of the rat embryonic XY gonadal ridge) was reduced by 2-fold relative to wild-type SRY at similar levels of mRNA expression. Chemical proteasome inhibition restored native-like SRY expression and transcriptional activity in association with restored occupancy of a sex-specific enhancer element in principal downstream gene Sox9, demonstrating that the variant SRY exhibits essentially native activity on a per molecule basis. Our findings define a novel mechanism of impaired organogenesis, accelerated ubiquitin-directed proteasomal degradation of a master transcription factor leading to a developmental decision poised at the edge of ambiguity. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

Paternal mtDNA and maleness are co-inherited but not causally linked in mytilid mussels.

Directory of Open Access Journals (Sweden)

Ellen L Kenchington

Full Text Available BACKGROUND: In marine mussels of the genus Mytilus there are two mitochondrial genomes. One is transmitted through the female parent, which is the normal transmission route in animals, and the other is transmitted through the male parent which is an unusual phenomenon. In males the germ cell line is dominated by the paternal mitochondrial genome and the somatic cell line by the maternal. Research to date has not allowed a clear answer to the question of whether inheritance of the paternal genome is causally related to maleness. METHODOLOGY/PRINCIPAL FINDINGS: Here we present results from hybrid crosses, from triploid mussels and from observations of sperm mitochondria in fertilized eggs which clearly show that maleness and presence of the paternal mitochondrial genome can be decoupled. These same results show that the female mussel has exclusive control of whether her progeny will inherit the mitochondrial genome of the male parent. CONCLUSIONS/SIGNIFICANCE: These findings are important in our efforts to understand the mechanistic basis of this unusual mode of mitochondrial DNA inheritance that is common among bivalves.

Full Text Available Host plant resistance is one of the major components to control sorghum shoot fly, Atherigona soccata. To understand the nature of gene action for inheritance of shoot fly resistance, we evaluated 10 parents, 45 F1’s and their reciprocals in replicated trials during the rainy and postrainy seasons. Genotypes ICSV 700, Phule Anuradha, ICSV 25019, PS 35805, IS 2123, IS 2146 and IS 18551 exhibited resistance to shoot fly damage across seasons. Crosses between susceptible parents were preferred for egg laying by the shoot fly females, resulting in a susceptible reaction. ICSV 700, ICSV 25019, PS 35805, IS 2123, IS 2146 and IS 18551 exhibited significant and negative general combining ability (gca effects for oviposition, deadheart incidence, and overall resistance score. The plant morphological traits associated with expression of resistance/ susceptibility to shoot fly damage such as leaf glossiness, plant vigor, and leafsheath pigmentation also showed significant gca effects by these genotypes, suggesting the potential for use as a selection criterion to breed for resistance to shoot fly, A. soccata. ICSV 700, Phule Anuradha, IS 2146 and IS 18551 with significant positive gca effects for trichome density can also be utilised in improving sorghums for shoot fly resistance. The parents involved in hybrids with negative specific combining ability (sca effects for shoot fly resistance traits can be used in developing sorghum hybrids with adaptation to postrainy season. The significant reciprocal effects of combining abilities for oviposition, leaf glossy score and trichome density suggested the influence of cytoplasmic factors in inheritance of shoot fly resistance. Higher values of variance due to sca (σ2s, dominance variance (σ2d, and lower predictability ratios than the variance due to gca (σ2g and additive variance (σ2a for shoot fly resistance traits indicated the predominance of dominance type of gene action, whereas trichome density, leaf

The importance of studying inherited hematological disorders in ancient Anatolian populations

Full Text Available Before analysis of DNA from ancient remains was possible, anthropologists studied evolution and migration patterns using data obtained from population genetic studies on modern populations combined with data obtained from morphological evaluations of ancient remains. Currently, DNA analysis of ancient populations is making a valuable contribution to these efforts. Researchers that perform ancient DNA analysis prefer to study polymorphisms on the Y chromosome or mitochondrial DNA because the results are easier to statistically evaluate. To evaluate polymorphisms on diploid genomes, which are more informative, only mutations that have been extensively examined in modern populations should be chosen. The most extensively evaluated mutations are those related to prevalent inherited disorders. As such, beta-thalassemia, sickle cell anemia, FVL mutation of globin and the factor V genes are good candidates for DNA studies in ancient populations. These mutations are common in Anatolia, host to many civilizations since the Paleolithic period. This history makes Anatolia a good place for conducting research that could enhance our understanding of human evolution and migration patterns.

The aim of this study was to assess the effectiveness of localized treatments to persistently stop epistaxis in patients with inherited bleeding disorders. In a self-controlled comparative clinical trial, to offer the best solution to stop epistaxis at home (within 10 minutes), patients with inherited bleeding disorders were treated using three different topical hemostatic agents, including Tranexamic acid impregnated tampon, EpiCell tampon prepared from oxidized regenerated cellulose pad, and ChitoHem tampon (reinforced with chitosan). The results of using these different products on three groups of randomly selected patients were ultimately compared using the χ(2) and Fisher's exact test statistics. A total of 31 patients, 5 females and 26 males with a mean age of 5.6 years, were included in the study. Twenty-three patients had Glanzmann disease, four had von-Willebrand disease, two had Bernard soulier syndrome, two had activated factor VII deficiency, and one patient had impaired secretion of adenosine deaminase. The study exhibited that statistically there was no significant difference between EpiCell tampon and Tranexamic acid impregnated tampon treatments with respect to the hemostasis duration. However, ChitoHem tampon was more efficient than Tranexamic acid impregnated tampon (P value stop epistaxis. We recommend further research on the use of other hemostatic agents for localized bleeding in patients with inherited bleeding disorders.

Middle school students' learning about genetic inheritance through on-line scaffolding supports

Science.gov (United States)

Manokore, Viola

The main goal of school science is to enable learners to become scientifically literate through their participation in scientific discourses (McNeill & Krajcik, 2009). One of the key elements of scientific discourses is the ability to construct scientific explanations that consist of valid claims supported by appropriate evidence (e.g., McNeill & Krajcik, 2006, Sadler, 2004; Sandoval & Reiser, 2004). Curricula scaffolds may help students construct scientific explanations and achieve their learning goals. This dissertation study is part of a larger study designed to support fifth through seventh grade students' learning about genetic inheritance through curricula scaffolds. Seventh grade students in this study interacted with a Web Based Inquiry Science Environment (WISE) unit called "From Genotype to Phenotype" that had curricula scaffolds. Informed by the Scaffolded Knowledge Integration, two versions of the unit were developed around concepts on genetic inheritance. Version one of the units was explicit on explaining to students how to make a claim and support it with appropriate evidence. Although the science concepts covered were the same, Version two was not explicit on claims and evidence use. Embedded in the units were scaffolding supports in the form of prompts. This dissertation study explored students' responses to the scaffolding support prompts using a knowledge integration (KI) rubric as described by Linn and His (2000). Two teachers, each with about 150 students in five classes of about 25 each, participated in the study. Each teacher had three classes of students that received a version one and the other two classed received version two of "From Genotype to Phenotype" unit. Using the Statistical Package for Social Scientists (SPSS), I explored whether students' scores, as measured by the KI rubric, varied by the unit version the students received or by the teacher they had. The findings suggested that the two versions of the unit were equally

The number of malformations attributed to mutations with autosomal or X-linked patterns of inheritance has increased steadily since the cataloging began in the 1960s. These diagnoses have been based primarily on the pattern of phenotypic features among close relatives. A malformations surveillance program conducted in consecutive pregnancies can identify both known and "new" hereditary disorders. The Active Malformations Surveillance Program was carried out among 289,365 births over 41 years (1972-2012) at Brigham and Women's Hospital in Boston. The findings recorded by examining pediatricians and all consultants were reviewed by study clinicians to establish the most likely diagnoses. The findings in laboratory testing in the newborn period were reviewed, as well. One hundred ninety-six (0.06%) infants among 289,365 births had a malformation or malformation syndrome that was attributed to Mendelian inheritance. A total of 133 (68%) of the hereditary malformations were attributed to autosomal dominant inheritance, with 94 (71%) attributed to apparent spontaneous mutations. Forty-six (23%) were attributed to mutations with autosomal recessive inheritance, 17 associated with consanguinity. Seventeen (9%) were attributed to X-linked inheritance. Fifteen novel familial phenotypes were identified. The family histories showed that most (53 to 71%) of the affected infants were born, as a surprise, to healthy, unaffected parents. It is important for clinicians to discuss with surprised healthy parents how they can have an infant with an hereditary condition. Future studies, using DNA samples from consecutive populations of infants with malformations and whole genome sequencing, will identify many more mutations in loci associated with mendelizing phenotypes.

Diagnosis and treatment strategies of thrombophilic risk factors

Directory of Open Access Journals (Sweden)

Murat Albayrak

2010-09-01

Full Text Available Thrombophilia is defined as the general name for a group of genetic and acquired situations, arising from defects of hemostasis mechanism and generating tendency to thrombosis. Examples of the acquired risk factors that increase the tendency to thrombosis are venous catheters, sepsis, surgery, hyperlipidemia, congestive heart disease, increased lipoprotein a, old age, antiphospholipid syndrome, nephrotic syndrome, hyperviscosity, chronic myeloproliferative neoplasms, paroxysmal nocturnal hemoglobinuria, heparin induced thrombocytopenia, vasculitis, immobility, obesity, major surgery, trauma, burns, malignancy, pregnancy and oral contraceptive usage. Genetic tendency to venous thromboembolism in early ages, even without any known cause, is named as thrombophilia. Factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase gene mutations, factor VIII elevation, protein C, protein S and antithrombin deficiency parameters are suggested for evaluation, in patient groups suspected of inherited thrombophilia. Detection of inherited thrombophilic factors in selected patient groups is a guide in developing treatment strategies and in establishing prognosis. Due to the genetic heterogeneities, each society should determine their thrombophilic risk pool. Thus, with the determination of the risk factors, unnecessary assessments will be prevented and a cost-effective approach can be developed.

Peripheral neuropathy is a common finding in patients with complex inherited neurological diseases and may be subclinical or a major component of the phenotype. This review aims to provide a clinical approach to the diagnosis of this complex group of patients by addressing key questions including the predominant neurological syndrome associated with the neuropathy, for example, spasticity, the type of neuropathy and the other neurological and non-neurological features of the syndrome. Priority is given to the diagnosis of treatable conditions. Using this approach, we associated neuropathy with one of three major syndromic categories: (1) ataxia, (2) spasticity and (3) global neurodevelopmental impairment. Syndromes that do not fall easily into one of these three categories can be grouped according to the predominant system involved in addition to the neuropathy, for example, cardiomyopathy and neuropathy. We also include a separate category of complex inherited relapsing neuropathy syndromes, some of which may mimic Guillain-Barré syndrome, as many will have a metabolic aetiology and be potentially treatable. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Common bermudagrass [C. dactylon (L.) Pers. var. dactylon] is economically and environmentally the most important member among Cynodon species because of its extensive use for turf, forage and soil erosion control in the world. However, information regarding the inheritance within the taxon is limited. Accordingly, the objective of this study was to determine qualitative inheritance mode in common bermudagrass. Two tetraploid (2n = 4x = 36), first-generation selfed (S1) populations, 228 progenies of 'Zebra' and 273 from A12359, were analyzed for segregation with 21 and 12 simple sequence repeat (SSR) markers, respectively. It is concluded that the inheritance mode of tetraploid bermudagrass was complete or near complete disomic. It is evident that the two bermudagrass parents had an allotetraploid genome with two distinct subgenomes since 33 SSR primer pairs amplified 34 loci, each having two alleles. Severe transmission ratio distortions occurred in the Zebra population while less so in the A12359 population. The findings of disomic inheritance and segregation ratio distortion in common bermudagrass is significant in subsequent linkage map construction, quantitative trait locus mapping and marker-assisted selection in the species.

1990-01-01

Analysis of the molecular basis of dominantly inherited β-thalassemia in four families has revealed different mutations involving exon 3 of the β-globin gene. It is suggested that the phenotypic difference between this condition and the more common recessive forms of β-thalassemia lies mainly in the length and stability of the abnormal translation products that are synthesized and, in particular, whether they are capable of binding heme and producing aggregations that are relatively resistant to proteolytic degradation

2015-01-01

Background The Dog Erythrocyte Antigen (DEA) 1 blood group system remains poorly defined. Objectives The purpose of the study was to determine the DEA 1 mode of inheritance and to characterize the DEA 1 antigen and alloantibodies. Animals Canine research colony families, clinic canine patients, and DEA 1.2+ blood bank dogs were studied. Methods Canine blood was typed by flow cytometry and immunochromatographic strips using anti-DEA 1 monoclonal antibodies. Gel column experiments with polyclonal and immunoblotting with monoclonal anti-DEA 1 antibodies were performed to analyze select samples. Cross-reactivity of human typing reagents against canine RBCs and one monoclonal anti-DEA 1 antibody against human RBC panels was assessed. Results Typing of 12 families comprising 144 dogs indicated an autosomal dominant inheritance with ≥4 alleles: DEA 1− (0) and DEA 1+ weak (1+), intermediate (2+) and strong (3+ and 4+). Samples from 6 dogs previously typed as DEA 1.2+ were typed as DEA 1+ or DEA 1− using monoclonal antibodies. Human typing reagents produced varied reactions in tube agglutination experiments against DEA 1+ and DEA 1− RBCs. Polypeptide bands were not detected on immunoblots using a monoclonal anti-DEA 1 antibody, therefore the anti-DEA 1 antibody may be specific for conformational epitopes lost during denaturation. Conclusions The autosomal dominant inheritance of DEA 1 with ≥4 alleles indicates a complex blood group system; the antigenicity of each DEA 1+ type will need to be determined. The biochemical nature of the DEA 1 antigen(s) appears different from human blood group systems tested. PMID:26291052

Guanine holes are prominent targets for mutation in cancer and inherited disease.

Directory of Open Access Journals (Sweden)

Albino Bacolla

Full Text Available Single base substitutions constitute the most frequent type of human gene mutation and are a leading cause of cancer and inherited disease. These alterations occur non-randomly in DNA, being strongly influenced by the local nucleotide sequence context. However, the molecular mechanisms underlying such sequence context-dependent mutagenesis are not fully understood. Using bioinformatics, computational and molecular modeling analyses, we have determined the frequencies of mutation at G • C bp in the context of all 64 5'-NGNN-3' motifs that contain the mutation at the second position. Twenty-four datasets were employed, comprising >530,000 somatic single base substitutions from 21 cancer genomes, >77,000 germline single-base substitutions causing or associated with human inherited disease and 16.7 million benign germline single-nucleotide variants. In several cancer types, the number of mutated motifs correlated both with the free energies of base stacking and the energies required for abstracting an electron from the target guanines (ionization potentials. Similar correlations were also evident for the pathological missense and nonsense germline mutations, but only when the target guanines were located on the non-transcribed DNA strand. Likewise, pathogenic splicing mutations predominantly affected positions in which a purine was located on the non-transcribed DNA strand. Novel candidate driver mutations and tissue-specific mutational patterns were also identified in the cancer datasets. We conclude that electron transfer reactions within the DNA molecule contribute to sequence context-dependent mutagenesis, involving both somatic driver and passenger mutations in cancer, as well as germline alterations causing or associated with inherited disease.

Venezuela-MEM/USA-DOE Fossil Energy Report XIII-1, Supporting Technology for Enhanced Oil Recovery, Microbial EOR

Energy Technology Data Exchange (ETDEWEB)

Ziritt, Jose Luis

1999-11-03

The results from Annex XIII of the Cooperative Agreement between the United States Department of Energy (DOE) and the Ministry of Energy and Mines of the Republic of Venezuela (MEMV) have been documented and published with many researchers involved. Integrate comprehensive research programs in the area of Microbial Enhanced Oil Recovery (MEOR) ranged from feasibility laboratory studies to full-scale multi-well field pilots. The objective, to cooperate in a technical exchange of ideas and information was fully met throughout the life of the Annex. Information has been exchanged between the two countries through published reports and technical meetings between experts in both country's research communities. The meetings occurred every two years in locations coincident with the International MEOR conferences & workshops sponsored by DOE (June 1990, University of Oklahoma, September 1992, Brookhaven, September 1995, National Institute of Petroleum and Energy Research). Reports and publications produced during these years are listed in Appendix B. Several Annex managers have guided the exchange through the years. They included Luis Vierma, Jose Luis Zirritt, representing MEMV and E. B. Nuckols, Edith Allison, and Rhonda Lindsey, representing the U.S. DOE. Funding for this area of research remained steady for a few years but decreased in recent years. Because both countries have reduced research programs in this area, future exchanges on this topic will occur through ANNEX XV. Informal networks established between researchers through the years should continue to function between individuals in the two countries.

Management of inherited ichthyoses is symptomatic. Despite treatment, skin symptoms have a major impact on patients' quality of life (QoL). To assess the short- and medium-term efficacy of hydrotherapy on QoL and clinical symptoms of patients with inherited ichthyosis. In this 9-month prospective, open-label, multicentre study, 20 children and 24 adults with ichthyosis were enrolled in several French reference and competence centres, 2 months before undergoing a 3-week treatment with specific hydrotherapeutic management at Avène Hydrotherapy Centre. At baseline (2 months before hydrotherapy), beginning (D0) and end of hydrotherapy (D18), and 3 and 6 months later at the reference and competence centres, patients self-assessed QoL using the Dermatology Life Quality Index (DLQI) or its paediatric version (Children's DLQI), and investigators evaluated ichthyosis severity using a specific clinical ichthyosis score. The DLQI scores were significantly improved not only at the end of the hydrotherapy treatment (-56% vs. baseline; mean ± SD 3·59 ± 4·30 at D18 vs. 8·35 ± 5·71 at D0; P hydrotherapy (-26% vs. baseline; mean ± SD 5·21 ± 5·11 vs. 6·89 ± 5·38; P = 0·03) (primary criterion). Clinical symptoms were also significantly improved at all post-treatment visits, with a decrease of the mean clinical ichthyosis score by -38% between D0 and D18, by -30% at 3 months and by -31% at 6 months vs. baseline. A 3-week treatment at Avène Hydrotherapy Centre provided significant and persisting improvement of QoL and clinical symptoms in patients with inherited ichthyoses. © 2011 The Authors.

An investigation was carried out, using an electron microscope technique, of the substructure of austenite in the 120Kh3G steel. It was shown that the austenite substructure, resulting from high-temperature mechanical working, is inherited on deep cooling by the low-temperature phase (martensite), and in subsequent heating is again inherited by austenite. If the disintegration of the hot-deformed austenite takes place in the pearlite phase, reheating gives rise to an austenite free from the substructure

Dominantly inherited isolated hyperparathyroidism (DIIH) is rare in childhood. It may be the first biochemical abnormality in the multiple endocrine neoplasia type I (MEN I) and type II (MEN II) syndromes. Its clinical course is usually asymptomatic or of low morbidity. Radiographic examination is most often normal. We describe six members of a family with distinctive phenotype and DIIH. Limited systemic symptoms and severe radiographic osteitis fibrosa cystica were further unusual features in this family. The diagnosis of DIIH was made only after a 9-year-old girl developed hypercalcaemic crisis after a pathological femoral fracture. Distinctive phenotype, unusual clinical course and unparalleled radiographic changes suggest a not yet described syndromic association. (orig.)

Inherited renal tubulopathies associated with metabolic alkalosis: effects on blood pressure.

Inherited tubular disorders associated with metabolic alkalosis are caused by several gene mutations encoding different tubular transporters responsible for NaCl renal handling. Body volume and renin-angiotensin-aldosterone system status are determined by NaCl reabsorption in the distal nephron. Two common hallmarks in affected individuals: hypokalemia and normal / high blood pressure, support the differential diagnosis. Bartter's syndrome, characterized by hypokalemia and normal blood pressure, is a heterogenic disease caused by the loss of function of SLC12A1 (type 1), KCNJ1 (type 2), CLCNKB (type 3), or BSND genes (type 4). As a result, patients present with renal salt wasting and hypercalciuria. Gitelman's syndrome is caused by the loss of funcion of the SLC12A3 gene and may resemble Bartter's syndrome, though is associated with the very low urinary calcium. Liddle's syndrome, also with similar phenotype but with hypertension, is produced by the gain of function of the SNCC1B or SNCC1G genes, and must be distinguished from other entities of inherited hypertension such as Apparently Mineralocorticoid Excess, of glucocorticoid remediable hypertension.

Clinical presentation of hypopituitarism in the neonate may be variable, ranging from absent to severe nonspecific symptoms and may be life-threatening in patients with adrenocorticotropic hormone deficiency. The LIM homeobox gene 4 (LHX4) transcription factor regulates early embryonic development of the anterior pituitary gland. Autosomal dominant mutations in LHX4 cause congenital hypopituitarism with variable combined pituitary hormone deficiency (CPHD). We report on a neonate with unexplained heart failure and minor physical anomalies, suggesting a midline defect. She was diagnosed with complete CPHD. Cardiac function was rescued by replacement with hydrocortisone and thyroxine; hypoglycaemia stopped under growth hormone therapy. Magnetic resonance imaging revealed a dysgenetic pituitary gland suggesting an early developmental defect. Array comparative genomic hybridization showed a maternally inherited 1.5-megabase microdeletion in 1q25.2q25.3, including the LHX4 gene. Haploinsufficiency of LHX4 likely explains the predominant pituitary phenotype in the proposita and we suggest variable intrafamilial penetrance of the inherited microdeletion. To the best of our knowledge, we are the first to report on heart failure as a rare nonspecific symptom of treatable CPHD in the newborn. Variably penetrant pituitary insufficiency, including this severe and atypical presentation, can be correlated with LHX4 insufficiency and highlights the role of LHX4 for pituitary development.

Information concerning inherited metabolic diseases in China is scarce. We investigated the prevalence and age distributions of amino acid, organic acid, and fatty acid oxidation disorders in Chinese patients. Blood levels of amino acids and acylcarnitines (tandem mass spectrometry) were measured in 18,303 patients with suspected inherited metabolic diseases. Diagnosis was based on clinical features, blood levels of amino acids or acylcarnitines, urinary organic acid levels (gas chromatography-mass spectrometry), and (in some) gene mutation tests. Inherited metabolic diseases were confirmed in 1,135 patients (739 males, 396 females). Median age was 12 months (1 day to 59 years). There were 28 diseases: 12 amino acid disorders (580 patients, 51.1%), with hyperphenylalaninemia (HPA) being the most common; nine organic acidemias (408 patients, 35.9%), with methylmalonic acidemia (MMA) as the most common; and seven fatty acid oxidation defects (147 patients, 13.0%), with multiple acyl-coenzyme A dehydrogenase deficiency (MADD) being the most common. Onset was mainly at 1-6 months for citrin deficiency, 0-6 months for MMA, and in newborns for ornithine transcarbamylase deficiency (OTCD). HPA was common in patients aged 1-3 years, and MADD was common in patients >18 years. In China, HPA, citrin deficiency, MMA, and MADD are the most common inherited disorders, particularly in newborns/infants. © 2014 Wiley Periodicals, Inc.

-class are specialized in sub-classes in a very primitive manner: they are simply re-defined and need not bear any resemblance of the virtual in the super-class. In BETA, a new object-oriented language, classes and methods are unified into one concept, and by an extension of the virtual concept, virtual procedures....../methods in sub-classes are defined as specializations of the virtuals in the super-class. The virtual procedures/methods of the sub-classes thus inherits the attributes (e.g. parameters) and actions from the “super-procedure/method”.

A benefit born as an inheritance from low-level radioactive waste is considered. In the present study, a direct economic scale of application of radiation in Japanese industry, agriculture and medicine is taken as parameter for quantifying the size of benefit. In 2006, the economic scale is about 21 billion dollars (b$) for industry, 2.5b$ for agriculture and 14b$ for medicine. Economic scale covered the all fields is totaled 37b$. Due to those benefit, one can drive a car and play an internet, pleasure the dinning food. Diagnosis and treatment by nuclear medicine can possible to survive the millions of lives and resulting in improving the quality of life, decreasing pain and suffering. However, most Japanese (80%>) may not aware those benefits to date. This report is prepared for aiming at disseminating those benefits to our peoples. (author)
