For past millennia, midwives have served women in childbirth. In premodern times, midwives were usually the only birth attendants. With the Industrial Revolution and the arrival of modernism, male physicians either replaced midwives or superceded them in the modernist medical hierarchy, leaving them with plenty of women to attend but with relatively little autonomy. As the new millennium dawns ...

Although son preference in patrilineal society is an established fact, daughter preference in matrilineal society is not thoroughly examined. Very few studies have been carried out on the issue. This paper attempts to explore the daughter preference and contraceptive-use in matrilineal tribal societies in Meghalaya, India. Data from the National Family Health Survey 1998-1999 have been used in ...

In budding yeast, asymmetric cell division yields a larger mother and a smaller daughter cell, which transcribe different genes due to the daughter-specific transcription factors Ace2 and Ash1. Cell size control at the Start checkpoint has long been considered to be a main regulator of the length of the G1 phase of the cell cycle, resulting in longer G1 in the smaller daughter cells. Our recent...

The aim of this study is to explore how Doris Lessing‟s works disclosein prominence the power dynamics of the conflicted and struggling relationship of mother and daughter, the paradigm of mother daughter relationship and its psychodynamics including explanations about the developmental stages of the relationship between the mother and the daughter, human behavior of the two in the context of r...

Three models were used to estimate heritabilities for milk yields at different production levels and for different years as twice the regression of daughter residual effects on dam residual effects. The denominator is the residual mean square for dams. The numerator is the difference between the residual term for sum of dam's and daughter's records and sum of residual terms for records of dams ...

Centrosomes comprise a pair of centrioles surrounded by an amorphous network of pericentriolar material (PCM). In certain stem cells, the two centrosomes differ in size, and this appears to be important for asymmetric cell division [1, 2]. In some cases, centrosome asymmetry is linked to centriole age because the older, mother centriole always organizes more PCM than the daughter centriole, thu...

The centriole, organizer of the centrosome, duplicates by assembling a unique daughter identical to itself in overall organization and length. The centriole is a cylindrical structure composed of nine sets of microtubules and is thus predicted to have nine-fold symmetry. During duplication, a daughter lacking discrete microtubular organization first appears off the wall of the mother centriole....

We examined the relationship between the spindle orientation and the determination site of cytokinesis in brown algal cells using polyspermic zygotes of Scytosiphon lomentaria. When two male gametes fuse with one female gamete, the zygote has two pairs of centrioles derived from male gametes and three chloroplasts from two male and one female gametes. Just before mitosis, two pairs of centriole...

Heritability estimates, by year of freshening of daughter, were obtained from daughter-dam and granddaughter-granddam regressions using 61,482 triply matched first lactations of artificially sired Holstein cows obtained from the Northeast Dairy Records Processing Laboratory. After adjusting for herd-year-season effects, residual effects may include additive and other genetic effects of the anim...
