small emission. This causes deflection from the linearity between the ratio and Ca 2+ concentration at very high Ca 2+ concentrations. We that found our equa- tion could be reasonably applied to [Ca 2+]m concentrations up to 50-fold that of the Kd. This range is reasonably accept- able under experimental conditions. The new equation still does not solve the problems of incomplete hydrolysis of... Fura-2 analogs are ratiometric fluoroprobes that are widely used for the quantitative measurement of [Ca2+]. However, the dye usage is intrinsically limited, as the dyes require ultraviolet (UV) excitation, which can also generate great interference, mainly from nicotinamide adenine dinucleotide (NADH) autofluorescence. Specifically, this limitation causes serious problems for the quantitative measurement of mitochondrial [Ca2+], as no available ratiometric dyes are excited in the visible range.... -

Y to Y'. The line XX' was measured in millimetres and correlated with the pen deflection at the same sensitivity of the oscillograph by a known weight. This correlation gave the tension at the start of linear phase i.e. Po in gms. Similarly, tension at the end of linear phase i.e. P1 was calculated by using line YY'. Measurement of initial (Lo) and final (L1) lengths at steepest rising... A new method is used to record the actual shortening produced during the auxotonic activity of the sartorius (SAR), gastrocnemius (CAS) and rectus abdominis (RAB) muscles of a lizard Uromastix. The auxotonic twitch and tetanus records thus obtained were used for the first time to calculate the coefficient of linear shortening (COLS). This coefficient represent the relative Index between change in length (Δ L=L0-L1) and tension (ΔP P0-P1) due to shortening at the steepest rising phase of the... -

traces there are individual openings (downward deflection) of Na channels. The patch was hyperpolarized by 30 mV, and 40 mV depolarizing pulses are given. The right side shows individual Ca-channel currents (adapted from Fenwick, Marty & Neher, 1981). Depolar- izing pulses as indicated were given from normal resting potential. The pipette contained isotonic Ba solution. Single channel... -

The purposes were 1) to compare load deflection rate(LDR) of MEAW with that of various other archwires in the individual interbracket span, 2)to compare the wire stiffness in the interbracket span with that in the multi-L-loop region (the span from distal border of the bracket of the lateral incisor to the mesial border of the buccal tube of second molar), and 3) to verify the... -
