A new method is described for continuously measuring cell turgor pressure (P), hydraulic conductivity (L(p)), and volumetric elastic modulus (epsilon) in higher plant cells, using a probe. This technique permits volume changes, DeltaV, DeltaP, to be determined with an accuracy of 10(-5) 10(-6) mul 3 5.10(-2) bar, respectively.The main principle the same as probe developed by Zimmermann Steudle which transmitted transducer means oil-filled capillary introduced into cell. In order use small...

"Spice" and other herbal blends were marketed in Germany until January 2009 as substances purportedly exerting similar effects to cannabis, yet containing no cannabinoids. These products recently forbidden under the provisions of German Narcotics Law after they found contain undeclared, synthetic cannabinomimetic substances. The authors describe physical withdrawal phenomena a dependence syndrome that developed consumption "Spice."A 20-year old patient reported he had smoked "Spice Gold"...
Summary The plant plasma membrane intrinsic protein, PIP1b, facilitates water transport. These features were characterized in Xenopus oocytes and it has asked whether aquaporins are relevant for transport plants. In order to elucidate this uncertainty Arabidopsis thaliana was transformed with an anti‐sense construct targeted the PIP1b gene. Molecular analysis revealed that lines have reduced steady‐state levels of highly homologous PIP1a mRNA. cell permeability analyzed by swelling...

Therefore, inflammatory reactions fibrotic overgrowth the beads result if Langerhans islets encapsulated in raw alginate hydrogel (cross‐linked divalent cations).

Rotation of single cells (mesophyll protoplasts Avena sativa) induced by a planar, homogeneous rotating field has been observed at frequency 20-40 kHz (conductivity the external mannitol solution 6x 10 -5 Ω -1 cm ). This variation in optimum is largely due to an inverse dependence on cell radius. direction opposite that field, and can be reversed will reversing field. The maximum speed spinning was few cycles per second (and thus always much slower than field) proportional square amplitude...
Direct measurements of the volumetric elastic modulus, in, cells a higher plant were performed on epidermal bladder Mesembryanthemum crystallinum using pressure probe technique. Measurements giant algal (Valonia, Nitellopsis) are given for comparison. Giant celled algae and M. bladders have moduli, which depend strongly turgor pressure, P, cell volume, V. The in values range between 5 bar at zero 100 full (3-4 bar). increased with size (volume) this volume dependence was pronounced more high...
