چکیده

Using videomicroscopy we present measurements of the fluctuation spectrum of giant vesicles containing bacteriorhodopsin pumps. When the pumps are activated, we observe a significant increase of the fluctuations in the low wave vector region, which we interpret as due to a lowering of the effective tension of the membrane.

Response of Fenugreek plants to short-term salinity stress in relation to lipid peroxidation, antioxidant activity and protein content

To investigate the effect of salinity stress on membrane stability index, membrane lipid peroxidation, catalase activity and protein content of Fenugreek (Trigonellafoenum) an experiment with five levels of short-term salinity stress (0, 50, 100, 150 and 200 mM) was carried out at the laboratory of agriculture faculty of Shahid Bahonar University of Kerman, Iran. The treatments were ar...

A decrease in membrane tension precedes successful cell-membrane repair.

We hypothesized that the requirement for Ca(2+)-dependent exocytosis in cell-membrane repair is to provide an adequate lowering of membrane tension to permit membrane resealing. We used laser tweezers to form membrane tethers and measured the force of those tethers to estimate the membrane tension of Swiss 3T3 fibroblasts after membrane disruption and during resealing. These measurements show t...

اندازه‌گیری فعالیت آدنیلیل سیکلاز غشاء سلولی در حضور پروتئین کموتاکسیک ماکروفاژ

 Adenylyl cyclase is a membrane-bound enzyme that catalyzes the conversion of ATP to cAMP. The inhibition of adenylyl cyclase was carried out by measuring the ability of the macrophage chemotactic protein-1 to inhibit the forskolin-induced enzyme activity. Measurement of adenylyl cyclase activity was performed according to the procedure described by Wiegn.  Adenylyl cyclase activity in the pres...

Electrical and mechanical characteristics of vascular smooth muscle response to norepinephrine and isoproterenol.

Effects of norepinephrine (NE) and isoproterenol on simultaneously recorded electrical and contractile activity in rat portal vein were studied using a sucrose-gap technique. This vascular smooth muscle shows spontaneous phasic contractions correlated with bursts of action potentials. Norepinephrine (10" to 10" w/v) increases the duration of the bursts and shortens the interval between bursts a...

Additivity of protein and nonprotein inhibitors of lung surfactant activity.

This study examined the degree of additivity of several physiologically relevant protein and nonprotein inhibitors in impairing the surface activity of whole and extracted calf lung surfactant (LS and CLSE) on a pulsating bubble apparatus at 37 degrees C. Inhibitors investigated were albumin, hemoglobin, C16:0 and C18:1 lysophosphatidylcholine (LPC), oleic acid (OA), palmitoleic acid (PA), arac...
