From an evolutionary perspective, matriliny presents a puzzle because men in matrilineal societies transmit wealth to their sisters’ sons, to whom they are only half as related as to their own sons. It has been argued that such systems would only maximise fitness under unrealistically high levels of paternity uncertainty. In this paper, we propose that matriliny can arise from daughterbiased in...

the aim of this research work is to study the impact of teaching the verbal communication pattern based on the holy quranic verses on the reduction of mother-daughter conflicts. three experimental groups (mothers, daughters and mothers-daughters) and one control group were selected from isfahan, iran using the cluster sampling method. the murray a. straus conflict tactics scale was utilized to ...

abstract background: hypotension and muscular cramp are the common complications of hemodialysis. effective control of hemodialysis complications increases the survival time and the quality of life of patients on hemodialysis. considering that failure to follow a therapeutic plan is one of the most prevalent causes of hemodialysis complications, the present research was conducted to study the e...

b a c k g r o u n d & aim: today, one of the leading causes of pathogenicity and mortality in patients undergoing hemodialysis is their failure to follow the treatment plan. the present research was con- ducted to compare effects of patient-centered  education with family-centered  education on adher- ence with the treatment program. methods & materials: this clinical trial was performed betwee...

One mechanism of generating cellular diversity is to distribute developmental potential asymmetrically to daughter cells at mitosis. Two observations described in this report suggest that the C. elegans HAM-1 protein functions in dividing neuroblasts to produce daughter cells that adopt distinct fates. First, HAM-1 is asymmetrically distributed to the periphery of certain mitotic cells, ensurin...

Replicative aging in yeast is asymmetric-mother cells age but their daughter cells are rejuvenated. Here we identify an asymmetry in pH between mother and daughter cells that underlies aging and rejuvenation. Cytosolic pH increases in aging mother cells, but is more acidic in daughter cells. This is due to the asymmetric distribution of the major regulator of cytosolic pH, the plasma membrane p...

The processes for repairing DNA daughter-strand gaps were studied in UV-irradiated uvrB, uvrB recB, uvrB recF, and uvrB recB recF cells of Escherichia coli K-12. The dimer-containing parental DNA was found to be joined to daughter strands during postreplication repair in all four strains examined. Therefore, both the major (recF-dependent) and the minor (recF recB-independent) gap-filling proce...

Five patients with hepatic (3), pelvic (1) or spinal (1) hydatid cysts received 10 mg/kg/d albendazole for 1-3 months prior to surgery. Daughter cysts were present in the spinal hydatid and in one patient with hepatic disease. Electron microscope examination of the cyst tissue of the pelvic and the 2 hepatic cysts lacking daughter cysts showed no evidence of germinal layer, and the protoscolece...

In the yeast Saccharomyces cerevisiae, organelles and macromolecular complexes are delivered from the mother to the emerging daughter during cell division, thereby ensuring progeny viability. Here, we have shown that during mitosis nuclear pore complexes (NPCs) in the mother nucleus are actively delivered through the bud neck and into the daughter cell concomitantly with the nuclear envelope. F...
