1. Estudo da colonizaÃÃo micorrÃzica arbuscular no desenvolvimento de minirosa em um Neossolo QuartzarÃnico do municÃpio de EusÃbio - CE / Study of arbuscular mycorrhizal colonization on the development of rose miniature in a Neosoil Quartzarenic of the EusÃbio county in Cearà state
O Estado do Cearà vem se destacando na Ãrea de produÃÃo de flores e plantas ornamentais nos Ãltimos anos e tem apresentado crescimento em vÃrios aspectos, influenciando, dessa maneira, no desenvolvimento da economia cearense. No entanto, apesar da grande importÃncia econÃmica das rosas no Cearà como tambÃm em outras regiÃes do Brasil, hà carÃnci

2. Effects of Acute Increases in Left Ventricular Preload on Indices of Myocardial Function in Conscious, Unrestrained and Intact, Tranquilized Baboons
The effects of acute volume loading were examined on indices of left ventricular (LV) function in conscious, unrestrained and intact, tranquilized baboons. Experiments were conducted 1-3 mo after implantation of ultrasonic transducers to measure LV internal diameter and wall thickness, and miniature LV pressure gauges and aortic and left atrial catheters. In

3. Effects of cardiac depression and of anesthesia on the myocardial action of a cardiac glycoside
The effects of ouabain (G-strophanthin) 20 μg/kg, on left ventricular (LV) pressure (P), diameter (D), velocity of contraction (dD/dt), and dP/dt were studied in conscious dogs instrumented with ultrasonic diameter gauges and miniature pressure gauges. The effects of ouabain were compared on separate occasions in the same dogs after cardiac depression with

4. Multipoint determination of pressure-volume curves in human intervertebral discs.
To gain further insight into the biomechanics of the human intervertebral disc and to determine a potential mechanism for causation and relief of symptoms related to a herniated disc, the pressure-volume relation was determined within the nucleus pulposus. Pressure was measured continuously within the nucleus pulposus in 17 intact lumbar discs from human cad

5. Voltage clamp analysis of excitatory synaptic transmission in the avian nucleus magnocellularis.
1. The properties of evoked excitatory postsynaptic currents (EPSCs) and spontaneous miniature excitatory postsynaptic currents (mEPSCs) have been studied in neurons of the nucleus magnocellularis (nMAG), one of the avian cochlear nuclei which receive somatic, calyceal innervation from auditory nerve fibres. Whole-cell patch clamp techniques were used to vol

6. Quantal transmitter release mediated by strontium at the mouse motor nerve terminal.
1. In isolated mouse diaphragm, nerve stimulation in the presence of Sr2+ evokes phasic quantal transmitter release (endplate potentials, EPPs) with the same time course as in the presence of Ca2+. 2. Brief tetanic trains of nerve stimuli in the presence of Sr2+ cause an increase in quantal content of EPPs accompanied by an increase in the frequency of minia

7. Surplus acetylcholine and acetylcholine release in the rat diaphragm.
1. Skeletal muscles from rat, mouse and frog were incubated under different conditions and the amounts of acetylcholine (ACh) extractable from the tissue and released into the medium were determined by mass fragmentography. In some experiments measurements were made of the amounts of ACh ('bound' ACh) surviving in a muscle homogenate to which an excess of ac

8. The kinetics of quantal releases during end-plate currents at the frog neuromuscular junction.
1. The preceding paper (Van der Kloot, 1988) described a method for estimating the timing of quantal releases during an end-plate current. This period of elevated quantal release is called the early release period or ERP (Barrett & Stevens, 1972b). In the present paper, this deconvolution method is used to study the effects of varying quantal output by extra
