Traditional and professional birth attendants influence on womens decisions of birth place and type of birth assistance : a qualitative study in Tang…

2012

Author's version of an article in the journal: Nordisk Sygeplejeforskning. Also available from the publisher at: http://www.idunn.no/ts/nsf/2012/01/art02 Almost half of all Tanzanian women deliver at home, alone, assisted by family members or traditional birth attendants. The aim of this article was to expand existing knowledge on how pregnant and laboring women's preferences and decisions of birth place and type of assistance are influenced. A qualitative study with semi-structured interviews, with two traditional birth attendants and one midwife, and a participatory observation was conducted at a health clinic in Tanga District, Tanzania. It was found that the interaction between pregnant…

Early handling effect on female rat spatial and non-spatial learning and memory

2014

This study aims at providing an insight into early handling procedures on learning and memory performance in adult female rats. Early handling procedures were started on post-natal day 2 until 21, and consisted in 15 min, daily separations of the dams from their litters. Assessment of declarative memory was carried out in the novel-object recognition task; spatial learning, reference- and working memory were evaluated in the Morris water maze (MWM). Our results indicate that early handling induced an enhancement in: (1) declarative memory, in the object recognition task, both at 1h and 24h intervals; (2) reference memory in the probe test and working memory and behavioral flexibility in the…

Corrigendum: Wired for motherhood: induction of maternal care but not maternal aggression in virgin female CD1 mice

2015

Virgin adult female mice display nearly spontaneous maternal care towards foster pups after a short period of sensitization. This indicates that maternal care is triggered by sensory stimulation provided by the pups and that its onset is largely independent on the physiological events related to gestation, parturition and lactation. Conversely, the factors influencing maternal aggression are poorly understood. In this study, we sought to characterize two models of maternal sensitization in the outbred CD1 strain. To do so, a group of virgin females (godmothers) were exposed to continuous cohabitation with a lactating dam and their pups from the moment of parturition, whereas a second group …

Drinking pattern matters: effects on maternal care and offspring vulnerability to alcohol in rats

2015

Alcohol drinking during pregnancy and post-partum period is a major concern because of the persistent neurobehavioral deficits in the offspring, which include increased vulnerability to substance abuse (1). The intermittent pattern of alcohol consumption induces higher drinking levels and deeper neurobiological changes in addiction-related brain regions, with respect to traditional free-access paradigms in male rats (2, 3). Nevertheless, no studies investigated on the effects of the drinking pattern on female subjects during pregnancy and perinatal time. To this aim, this study explored the consequences of continuous vs. intermittent drinking pattern on maternal behaviour and on offspring v…

Patterns matter: continuous Vs intermittent access to ethanol differently affects withdrawal behavioural phenotype and maternal care in female rats.

2014

Modeling voluntary ethanol consumption in female rats is crucial for gaining further insight in gender-related vulnerability to alcohol. Since ethanol effects depend not only on the amount consumed, but also on drinking pattern, this study aimed at assessing the influence of continuous and intermittent ethanol self-administration on peculiar aspects of female behavioural repertoire during withdrawal and relapse. Female rats undergoing a 15-week-long, 20% ethanol continuous or intermittent (3days/week) access, respectively named CARs and IARs, were tested for alcohol intake (gr/kg) and preference. During withdrawal we assessed: novelty and reward preference in novel object exploration and sa…

Data from: Paternal signature in kin recognition cues of a social insect: concealed in juveniles, revealed in adults

2014

Kin recognition is a key mechanism to direct social behaviours towards related individuals or avoid inbreeding depression. In insects, recognition is generally mediated by cuticular hydrocarbon (CHC) compounds, which are partly inherited from parents. However, in social insects, potential nepotistic conflicts between group members from different patrilines are predicted to select against the expression of patriline-specific signatures in CHC profiles. Whereas this key prediction in the evolution of insect signalling received empirical support in eusocial insects, it remains unclear whether it can be generalized beyond eusociality to less-derived forms of social life. Here, we addressed this…

Data from: Negative association between parental care and sibling cooperation in earwigs: a new perspective on the early evolution of family life?

2015

The evolution of family life requires net fitness benefits for offspring, which are commonly assumed to mainly derive from parental care. However, an additional source of benefits for offspring is often overlooked: cooperative interactions among juvenile siblings. In this study, we examined how sibling cooperation and parental care could jointly contribute to the early evolution of family life. Specifically, we tested whether the level of food transferred among siblings (sibling cooperation) in the European earwig Forficula auricularia (1) depends on the level of maternal food provisioning (parental care), and (2) is translated into offspring survival, as well as female investment into futu…

Data from: Mother and offspring fitness in an insect with maternal care: phenotypic trade-offs between egg number, egg mass and egg care

2014

Background: Oviparous females have three main options to increase their reproductive success: investing into egg number, egg mass and/or egg care. Although allocating resources to either of these three components is known to shape offspring number and size, potential trade-offs among them may have key impacts on maternal and offspring fitness. Here, we tested the occurrence of phenotypic trade-offs between egg number, egg mass and maternal expenditure on egg care in the European earwig, Forficula auricularia, an insect with pre- and post-hatching forms of maternal care. In particular, we used a series of laboratory observations and experiments to investigate whether these three components n…

Depresijas un uztvertā emocionālā siltuma bērnībā saistība ar mātes narcistiskām personības iezīmēm 18-44 gadus veciem pieaugušajiem

2022

Pētījuma mērķis bija izpētīt saistības starp depresiju, uztverto emocionālo siltumu bērnībā un mātes narcistiskām personības iezīmēm 18 – 44 gadus veciem pieaugušajiem. Pētījums tika veikts divās atkarīgās izlasēs. Pirmo izlasi veido 80 pieaugušie vecumā no 18 līdz 44 gadiem (M = 30,04, SD = 7,75), kas aizpildīja Epidemioloģijas pētījumu centra depresijas skalu (Center for Epidemiologic Studies Depression Scale (Eaton, Muntaner, Smith, Tien & Ybarra, 2004)), Latvijā aptauju adaptējušas M.
