two hundred and twenty five school going girls belonging to three districts of hazara division, pakistan were sampied for rubella antibodies. age range selected was 5 to 15 years. igg was positive in 7x.22% of cases and igm in 24.44% of cases. the antibodies pattern and prevalence was the same in all the three districts. a clear increase of igg was seen up to the age of ii years but between 12 ...

Properties of discrete cake-cutting procedures that use a minimal number of cuts (n – 1 if there are n players) are analyzed. None is always envy-free or efficient, but divideand-conquer (D&C) minimizes the maximum number of players that any single player may envy. It works by asking n ≥ 2 players successively to place marks on a cake that divide it into equal or approximately equal halves, the...

BACKGROUND AND AIMS Plastids undergo a process of binary fission in order to replicate. Plastid replication is required at two distinct stages of plant growth: during cell division to ensure correct plastid segregation, and during cell expansion and development to generate large populations of functional plastids, as in leaf mesophyll cells. This review considers some of the recent advances in ...

Cell Division is an open access, peer-reviewed journal that encompasses all aspects of cell cycle control and cancer in eukaryotes. Cell Division provides an online forum for the cell-cycle community by: publishing articles on all exciting aspects of cell-cycle research bridging the gap between models of cell cycle regulation, development, and cancer biology. This forum is driven by special...

S Tumps in animal cells (reviewed by Rappaport, 1986; Satterwhite and Pollard, 1992; Fishkind and Wang, 1995) provide a view of cytokinesis whereby in each dividing cell, a contractile ring of interdigitated anti-parallel actin and bipolar myosin (nonmuscle myosin II) filaments forms in the equatorial region of the cell cortex, and then constricts, in purse string-like fashion, to pinch the cel...
