“Gender, sex role orientation and dream recall frequency”: Correction.

Reports an error in "Gender, sex role orientation, and dream recall frequency" by Michael Schredl and Olaf Lahl (Dreaming, 2010[Mar], Vol 20[1], 19-24). In the article, a third author was not listed in the byline and some acknowledgment information was also missing: Third Co-Author: Anja S. G?ritz, University of Würzburg, Würzburg, Germany. The name appears in this record. Additional Acknowledgment: We thank the operators of the sites www.panopia.de, www.yougov.de, and www.studivz.net for providing participants. This work was in part supported by DFG grant GO 1107/4-1 to G?ritz. The online version of the article has been corrected. (The following abstract of the original article appeared in record 2010-05656-002.) Recently, a large meta-analysis showed that women tend to recall their dreams more often than men. Despite this robust finding, studies focused on explaining the gender difference in dream recall frequency are scarce. The present findings of an online survey indicate that sex role orientation—expressivity/femininity—was related to dream recall frequency but did not fully explain the gender difference in dream recall frequency. Future studies should investigate other variables—in addition to sex role orientation—like verbal memory, recall of emotional experiences, and/or frequency of talking about emotional matters that might play a role in explaining the gender difference in dream recall.

Apolipoprotein E (ApoE) polymorphism is related to differences in potential fertility in women: a case of antagonistic pleiotropy?

The alleles that are detrimental to health, especially in older age, are thought to persist in populations because they also confer some benefits for individuals (through antagonistic pleiotropy). The ApoE4 allele at the ApoE locus, encoding apolipoprotein E (ApoE), significantly increases risk of poor health, and yet it is present in many populations at relatively high frequencies. Why has it not been replaced by natural selection with the health-beneficial ApoE3 allele? ApoE is a major supplier of cholesterol precursor for the production of ovarian oestrogen and progesterone, thus ApoE has been suggested as the potential candidate gene that may cause variation in reproductive performance. Our results support this hypothesis showing that in 117 regularly menstruating women those with genotypes with at least one ApoE4 allele had significantly higher levels of mean luteal progesterone (144.21 pmol l⁻¹) than women with genotypes without ApoE4 (120.49 pmol l⁻¹), which indicates higher potential fertility. The hormonal profiles were based on daily data for entire menstrual cycles. We suggest that the finding of higher progesterone in women with ApoE4 allele could provide first strong evidence for an evolutionary mechanism of maintaining the ancestral and health-worsening ApoE4 allele in human populations.

Partner Experiences of “Near-Miss” Events in Pregnancy and Childbirth in the UK: A Qualitative Study

Objective

Severe life-threatening complications in pregnancy that require urgent medical intervention are commonly known as “near-miss” events. Although these complications are rare (1 in 100 births), there are potentially 8,000 women and their families in the UK each year who live through a life-threatening emergency and its aftermath. Near-miss obstetric emergencies can be traumatic and frightening for women, and their impact can last for years. There is little research that has explored how these events impact on partners. The objective of this interview study was to explore the impact of a near-miss obstetric emergency, focusing particularly on partners.

Design

Qualitative study based on narrative interviews, video and audio recorded and transcribed for analysis. A qualitative interpretative approach was taken, combining thematic analysis with constant comparison. The analysis presented here focuses on the experiences of partners.

Participants

Maximum variation sample included 35 women, 10 male partners, and one lesbian partner who had experienced a life-threatening obstetric emergency.

Setting

Interviews were conducted in participants’ own homes.

Results

In the hospital, partner experiences were characterized by powerlessness and exclusion. Partners often found witnessing the emergency shocking and distressing. Support (from family or staff) was very important, and clear, honest communication from medical staff highly valued. The long-term emotional effects for some were profound; some experienced depression, flashbacks and post-traumatic stress disorder months and years after the emergency. These, in turn, affected the whole family. Little support was felt to be available, nor acknowledgement of their ongoing distress.

Conclusion

Partners, as well as women giving birth, can be shocked to experience a life-threatening illness in childbirth. While medical staff may view a near-miss as a positive outcome for a woman and her baby, there can be long-term mental health consequences that can have profound impacts on the individual, but also their families.     

DNA-PCR system FGA (FIBRA)--genotype and allele frequencies in a sample of western Germany (Düsseldorf region)

Frequency data for the STR system FGA (HumFibra) were obtained from a Caucasoid German population sample (Düsseldorf area) of 424 unrelated individuals. PCR products were detected by horizontal polyacrylamid gel electrophoresis and a total of 16 alleles was identified by side-by-side comparison with a commercially available sequenced ladder. The observed genotype distribution showed no significant deviation from the Hardy-Weinberg equilibrium. The high information content (pooled German data: rate of heterozygosity = 0.8626; probability of match = 0.0344; mean exclusion chance = 0.7240) render this system a useful tool not only in forensic casework (criminal and paternity cases) but in population genetics too.     

Encystment Processes and the “Matrioshka-like Stage” in a Moss-dwelling and in a Limnic Species of Eutardigrades (Tardigrada)

Tardigrades have two forms of dormancy, namely cryptobiosis and encystment. The encystment is a form of diapause known for a limited number of species of tardigrades and still little studied. To increase the knowledge on encystment, two species of eutardigrades from Italy have been considered: the moss-dwelling Amphibolus volubilis (Eohypsibiidae), and the limnic Dactylobiotus parthenogeneticus (Murrayidae). Cysts have been collected in nature, or induced under laboratory conditions. In the latter case, it was possible to follow the several steps of encystment processes. Two different types of cyst (“type 1” and “type 2”) have been found in A. volubilis, while in D. parthenogeneticus only one type has been found. In general, the ovoid-shaped cysts are constituted by a series of cuticles surrounding the animals and resemble an onion or a Matrioshka Russian doll. In all three types of cyst, the encystment processes show both common and peculiar traits. Encystment begins with the discharging of the sclerified parts of the buccal-pharyngeal apparatus, as in the molting process, but without the loss of the old cuticle. Then, two or three new cuticles are serially synthesized, according to cyst type. In A. volubilis, the ultrastructure of these new cuticular involucra is similar to that of non-encysted animal cuticles, while in D. parthenogeneticus the ultrastructure of the new cuticular involucra differs from that of non-encysted animal cuticle. A modified buccal-pharyngeal apparatus has been observed both in “type 2” cyst of A. volubilis and in the D. parthenogeneticus cyst.
