The constancy of cell volume under physiological conditions is generally thought to reflect a balance between solute influx and efflux and is therefore critically dependent on the properties of the plasma membrane. Despite a number of unanswered ques

A difficulty sometimes encountered in least-squares fitting of a one-compartment model with first-order absorption is that estimated values (ka and ke) of the rate constants of absorption and elimination are almost identical, are highly correlated an

To determine whether the Na+-K+-2Cl- symport or the parallel Na+/H+ and Cl-/HCO3- antiports provide the dominant pathway for NaCl uptake into the ciliary epithelium. Both pathways are known to support NaCl entry from the stroma into the pigmented cil

Sperm have generally been supposed to penetrate the zona pellucida surrounding the mammalian egg with the aid of a protease, acrosin. Difficulties associated with this view are discussed and an alternative, mechanical hypothesis introduced. The calcu

1. The development of the electrical and contractile properties of slow anterior latissimus dorsi (ALD) and fast posterior latissimus dorsi (PLD) muscles of the chick was studied. 2. At the earliest ages studied (14-16 days of incubation), the membra

Explant cultures were prepared from the slow anterior latissimus dorsi muscle and the fast posterior latissimus dorsi muscle of 15 day chick embryos. The morphology and growth pattern of myotubes from the two types of muscle were very similar. Intrac
