Striae Gravidarum

Having traced in 250 women the relationship between the tendency to form pregnancy scars and the woman's constitution, Seynsche (Zentr. F. Gyn., 1926, no. 27) found that there is a certain relationship between them, namely, in women with a clearly expressed female type, this tendency expressed much more sharply than in male-type women. The number of pregnancies in women does not have a significant effect on scar formation; a secondary role in this process is played by the age when a woman has her first birth.

Neonatal Castration

Synapses develop at similar rates in the suprachiasmatic nucleus of rats of both sexes, but values are higher in male than in female animals from birth to maturity. Male-type development cannot be mimicked by neonatal androgenization but results suggest that female-type development can be induced by neonatal castration of males. The results suggested that both prenatal and postnatal androgens are essential to normal male development.

The authoress has studied the characters of the pelvis in sixteen skeletons of male criminals in Lombroso's museum. In her paper she gives the details of the examination in each case, with tables summarising the results for the whole series. She finds that the pelvis in the criminal tends to approximate to the female type; and, though this type is generally admitted to be morphologically higher than the male type, she argues that the lack of sexual differentiation implied by this resemblance is to be properly regarded as an atavistic character, especially as it is in many cases associated with other peculiarities of a distinctly prehuman kind.

The Relationship

SummaryPostponing the start of childbearing raises the question of fertility postponed versus fertility foregone. One of the limitations of previous studies of ‘How late can you wait?’ is that any observed decline in the probability of conception with age could be due to a decline in fecundability with age or due to a decline in coital frequency with age or due to both factors. Using data from a multinational longitudinal study conducted to determine the daily probability of conception among healthy subjects, a discrete-time event history model with long-term survivors (sterile population) is used to study the relationship between age and fecundability for childless women, while controlling for the pattern of intercourse within a menstrual cycle. The findings suggest that women can wait until their early thirties to try for a first birth, providing that they are not already sterile, as the magnitude of the decline in fecundability is very modest and of little practical importance.

AbstractThe study of Agrippa's works confirms his constant interest in the theory and practice of alchemy. The apparent contradiction between De occulta philosophia, which uses alchemical doctrines, and De vanitate scientiarum, where alchemy is harshly criticized, is to be resolved in the light of a moral and cultural reform founded on a Hermetic-Christian perspective on the relationship between faith and reason. The analysis of the alchemic passages in De occulta philosophia proves that Agrippa's transmutatory operations have no secondary role in his 'restored' magic. Furthermore, these operations are oriented towards a utopia, where original unity is to be regained.

Early milk ejection, prolonged parturition and periparturient oxytocin release in the pig

The Relationship

AbstractPlasma oxytocin was measured in 11 multiparous sows for 13 h after the start of parturition to confirm the existence of early milk ejections and determine whether they were associated with pulsatile oxytocin release. The relationship between oxytocin concentrations and duration of parturition was also analysed. Oxytocin was released in pulses during and after parturition and mean concentrations reached maximum 2 to 4 h after the first birth. Discrete milk ejections occurred during parturition but only 42% of these were associated with oxytocin peaks before 4 hpost partum. After this more than 80% of milk ejections occurred with oxytocin peaks. Sow grunting increased during milk ejections and peak grunt rate increased after parturition. Oxytocin peaks without milk ejections did not lead to an increased rate of grunting. Sows with prolonged parturition had lower basal and peak oxytocin concentrations. During the first 4 h only half of the piglets were born during an oxytocin peak. Discrete milk ejections with oxytocin peaks can occur before parturition is completed. However, during the first 4 hpost partum, basal oxytocin concentrations may be high enough for milk ejection to occur without further oxytocin secretion. Both milk ejection and oxytocin release are necessary for the sow to increase grunt rate. Low oxytocin concentration is associated with prolonged parturition.

Summary This article aims to present the impact of social networks on the formation on the flow of blood and its components in the civilian blood donation system in Poland. The civilian blood donation system in Poland consists of 21 independently-functioning supply chains of blood and its components (Szołtysek, Twaróg 2009, p. 15). Today, logistics plays a secondary role in the management of blood supply chains, and the integration of flow is performed randomly and intuitively. The rapidly growing recognition of social logistics (T. Takahasi 1988, pp. 245 - 251; Tenhunen 2008, pp. 515-534; Szołtysek 2010, pp. 2-6; Szołtysek 2011, pp.13-18) provides tools to improve the efficiency of the blood donation system in terms of both the existing blood supply chains, and the potential offered by network structures. An unexpected change in demand for blood and its components probably induces a bullwhip effect, and the organizations that form the chains have to deal with supplies unreasonable in terms of their size and structure. A major role in this process is played by social networks, as a source of general mobilization among potential blood donors. Finding a way to change the relationship between social networks and the system of blood donation may minimize the disruptions occurring in the flow of blood and its components in Poland.

Female Phenotype

Here we provide descriptions of gynandromorphs of two species oil-collecting bees: Lophopedia nigrispinis and Epicharis iheringii, both with partial bilateral phenotypic asymmetry. The bees have a female phenotype predominantly on mesosoma and metasoma. The specimen of L. nigrispinis has distinct characteristics on legs, suggesting a mosaic pattern of gynandromorphism. The pollen and oil loads on legs suggest that the bee was foraging normally. The gynander specimen of E. iheringii has mostly a female phenotype, except for head, with right half female type and left half male type. The specimen of L. nigrispinis was collected foraging on flowers of Bidens sp. at Parque Nacional Iguazú, Argentina with loads of pollen on legs suggesting it was reproductive and was provisioning a nest. The specimen of Epicharis iheriingi has no evidence of any oil or pollen collection, despite its mostly female phenotype.
