Most of the time, two like pieces attack each other mutually, meaning they are both paralysed (en passant pawn captures are an exception to this, since the attack is not mutual.Newington Green Unitarian ChurchPolysomy: Polysomy is a condition found in many species, including fungi, plants, insects, and mammals, in which an organism has at least one more chromosome than normal, i.e.Manhood for Amateurs: Manhood For Amateurs is a 2009 collection of essays by the American writer Michael Chabon.Index of sociology articles: This is an index of sociology articles.

(1/930) Recurrence of Marfan syndrome as a result of parental germ-line mosaicism for an FBN1 mutation.
Mutations in the FBN1 gene cause Marfan syndrome (MFS), a dominantly inherited connective tissue disease. Almost all the identified FBN1mutations have been family specific, and the rate of new mutations is high. We report here a de novo FBN1mutation that was identified in two sisters with MFS born to clinically unaffected parents. The paternity and maternity were unequivocally confirmed by genotyping. Although one of the parents had to be an obligatory carrier for the mutation, we could not detect the mutation in the leukocyte DNA of either parent. To identify which parent was a mosaic for the mutation we analyzed several tissues from both parents, with a quantitative and sensitive solid-phase minisequencing method. The mutation was not, however, detectable in any of the analyzed tissues. Although the mutation could not be identified in a sperm sample from the father or in samples of multiple tissue from the mother, we concluded that the mother was the likely mosaic parent and that the mutation must have occurred during the early development of her germ-line cells. Mosaicism confined to germ-line cells has rarely been reported, and this report of mosaicism for the FBN1 mutation in MFS represents an important case, in light of the evaluation of the recurrence risk in genetic counseling of families with MFS.

(2/930) Immunization determinants in the eastern region of Ghana.
A study of the immunization determinants of children aged 12 to 18 months was conducted in 1991 in the Eastern Region of Ghana, using structured interviews of mothers and fathers. The completion of immunization schedules by one year, among the 294 children, was positively associated (P < 0.005) with the town of residence of the child and mother, the ability of the mother to speak English, the target child having been treated for illness at the local hospital, the child's mother having given birth to less than 5 children, the possession of a sewing machine by the mother, and the birth of the child in the current town of residence. Significantly higher immunization coverage levels were achieved where the Under Fives' Clinic was an affordable and acceptable service, integrating preventive and curative care, and where measures were implemented by the community to increase attendance levels at the Clinic. This was achieved among a target group who were otherwise at a relatively high risk of failing to complete immunization schedules on-time. (+info)
(3/930) Indicators of socioeconomic status for adolescents: the WHO Health Behaviour in School-aged Children Survey.
Many indicators of socioeconomic status used for adults are inappropriate for use in research on adolescents. In a school-based survey of 4079 Scottish schoolchildren using a self-completion questionnaire, over 20% of 11-15 year olds were unable to provide a substantive response on father's occupation. In contrast, indicators derived to construct a family affluence scale, which included car ownership, telephone ownership and the child having their own unshared bedroom, resulted in a 98% response rate; and 92% of children responded to a question on their weekly spending money. The intercorrelations between the conventional indicator of father's occupation and each family affluence and spending money were examined, and their associations with a range of health indicators and health behaviour measures compared. Father's occupational status and family affluence were moderately correlated and showed broadly similar patterns of association with the selected health measures although there were also some distinct differences. Child's spending money was only weakly correlated with father's occupation and showed rather different patterns of association with health measures. A case is made for the use of multiple indicators of socioeconomic status in adolescent health surveys, and it is argued that that the family affluence scale provides a useful and easily applied additional indicator to father's occupation or an alternative measure of socioeconomic background where occupational data are unavailable.

(4/930) Modulation of allospecific CTL responses during pregnancy in equids: an immunological barrier to interspecies matings?
Maternal immune recognition of the developing conceptus in equine pregnancy is characterized by the strongest and most consistent alloantibody response described in any species, a response directed almost exclusively against paternal MHC class I Ags. This work investigated the cellular immune response to paternal MHC Ags in pregnant and nonpregnant horses and donkeys, and in horses carrying interspecies hybrid mule conceptuses. We observed profound decreases in classical, MHC-restricted, CTL activity to allogeneic paternal cells in peripheral blood lymphocytes from both horse mares and donkey jennets carrying intraspecies pregnancies, compared with cells from nonpregnant controls. This is the first evidence in a randomly bred species for a generalized systemic shift of immune reactivity away from cellular and toward humoral immunity during pregnancy. Surprisingly, mares carrying interspecies hybrid mule conceptuses did not exhibit this transient, pregnancy-associated decrease in CTL activity. The failure of interspecies pregnancy to down-regulate cellular immune responses may be a heretofore-unrecognized, subtle barrier to reproductive success between species. (+info)
(5/930) Long-term effects on sexual function and fertility after treatment of testicular cancer.
This retrospective study evaluates the types and incidences of sexual disturbances and fertility distress in patients cured from testicular cancer and examines whether there is an effect resulting from different treatment modalities. A self-reported questionnaire was sent to 124 randomly selected patients who were treated at Hanover University Medical School between 1970 and 1993. Ninety-eight patients were included in the study, representing a response rate of 78%. All patients had been in complete remission (CR) for at least 24 months. The median age at diagnosis was 28 years (range 17-44). The median follow-up at the time of study was 12.0 years (range 2.8-25.6). Twenty patients (20%) had been treated for seminomatous and 78 patients (80%) for non-seminomatous germ cell tumours. Treatment included surveillance (7%), primary retroperitoneal lymph node dissection (RPLND) (13%), chemotherapy (CT) (33%), CT + secondary resection of residual retroperitoneal tumour mass (SRRTM) (43%) and infradiaphragmatic radiotherapy (4%). Patients receiving two treatment modalities (CT+SRRTM) reported more frequent an unfulfilled wish for children. Inability of ejaculation was clearly associated with RPLND and SRRTM. Subjective aspects of sexuality, like loss of sexual drive and reduced erectile potential, occurred only in a minority of patients after treatment. No abnormalities were observed concerning the course of pregnancies of partners. In conclusion, sexual dysfunction and infertility are common long-lasting sequelae in testicular cancer survivors affecting approximately 20% of patients. The relative risk for infertility appeared to be elevated for patients treated with the combination of CT+SRRTM. Twenty-one of 40 patients were able to fulfil their wish for children, and no congenital abnormalities were observed in these children. (+info)
(6/930) Excessive paternal transmission in psoriatic arthritis.
OBJECTIVE: The differential expression of a disease according to the sex of the disease-transmitting parent has been demonstrated in several autoimmune disorders. The purpose of the present study was to determine whether there are differences in the transmission and expression of psoriatic arthritis (PsA) that are dependent on the sex of the affected parent. METHODS: All probands (patients with PsA) were identified from among the patients attending the University of Toronto Psoriatic Arthritis Clinic. A self-reported family history of psoriasis or PsA was noted for each proband. Differences in parental and offspring transmission with respect to the proband were evaluated. In addition, the expression of PsA according to the sex of the affected parent was assessed at the time of the proband's presentation to the clinic. RESULTS: Ninety-five probands had affected parents: 62 (65%) had an affected father, and 33 (35%) had an affected mother. Thus, the proportion of paternal transmission (0.65) was significantly greater than was expected (0.5) (P = 0.001). Twelve of 74 offspring from male probands (16.2%) were affected with psoriasis or PsA, as compared with 9 of 108 offspring from female probands (8.3%) (P = 0.10). Probands whose fathers were affected had a higher frequency of skin lesions prior to arthritis (P = 0.047), an erythrocyte sedimentation rate > 15 mm/hour (P = 0.044), and a lower incidence of rheumatoid factor (P = 0.044). No differences were noted with respect to age at the onset of psoriasis or PsA, the severity of the PsA, or the frequency of HLA antigens. CONCLUSION: There appears to be excessive paternal transmission in PsA. Further clinical confirmation and elucidation of its genetic basis is warranted. (+info)
(7/930) Excess maternal transmission of type 2 diabetes. The Northern California Kaiser Permanente Diabetes Registry.
OBJECTIVE: To assess excess maternal transmission of type 2 diabetes in a multiethnic cohort. Previous studies have reported higher prevalence of diabetes among mothers of probands with type 2 diabetes than among fathers. This analysis is vulnerable to biases, and this pattern has not been observed in all populations or races. RESEARCH DESIGN AND METHODS: We assessed evidence for excess maternal transmission among 42,533 survey respondents with type 2 diabetes (probands) by calculating the prevalence of diabetes in their siblings and offspring. To assess data quality, we evaluated completeness of family history data provided. Accuracy of family information reported by probands was also evaluated by comparing survey responses in a subsample of 206 probands with family histories modified after further interviews with relatives. RESULTS: Siblings (n = 60,532) of probands with affected mothers had a greater prevalence of diabetes (20%) than those with affected fathers (17%) (P < 0.001 for adjusted odds ratios). Prevalence of diabetes was higher among the offspring (n = 72,087) of female (3.4%) versus male (2.2%) probands (P < 0.001 for adjusted odds ratios). These patterns were evident in all races and both sexes; however, the effect size was clinically insignificant in African-Americans and male offspring. In general, probands provided more complete data about diabetes status for the maternal arm of the pedigree than the paternal arm. Completeness of knowledge was not related to proband sex, but was related to education and race, and inversely to age. Accuracy of proband-reported family history was consistently good (kappa statistics generally > 0.70). CONCLUSIONS: Excess maternal transmission was observed in all races and both sexes, although the size of the excess was negligible in African-Americans and male offspring. Potential reporting and censoring biases are discussed. (+info)
(8/930) Evaluation of parental mitochondrial inheritance in neonates born after intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) is now used when severe male-factor infertility has been documented. Since defective mitochondrial functions may result in male hypofertility, it is of prime importance to evaluate the risk of paternal transmission of an mtDNA defect to neonates. DNA samples from the blood of 21 infertile couples and their 27 neonates born after ICSI were studied. The highly polymorphic mtDNA D-loop region was analyzed by four PCR-based approaches. With denaturing gradient gel electrophoresis (DGGE), which allows 2% of a minor mtDNA species to be detected, the 27 newborns had a DGGE pattern identical to that of their mother but different from that of their father. Heteroplasmy documented in several parents and children supported an exclusive maternal inheritance of mtDNA. The parental origin of the children's mtDNA molecules also was studied by more-sensitive assays: restriction-endonuclease analysis (REA) of alpha[32P]-radiolabeled PCR products; paternal-specific PCR assay; and depletion of maternal mtDNA, followed by REA. We did not detect paternal mtDNA in nine neonates, with a sensitivity level of 0.01% in five children, 0.1% in two children, and 1% in two children. The estimated ratio of sperm-to-oocyte mtDNA molecules in humans is 0.1%-1.5%. Thus, we conclude that, in these families, the ICSI procedure performed with mature spermatozoa did not alter the uniparental pattern of inheritance of mtDNA. (+info)
