The hypothesis that nexuses between cells are responsible for the core conductor properties of tissues was tested using smooth muscle preparations from the taenia coli of guinea pigs. Action potentials recorded from small diameter preparations across a sucrose gap change from monophasic to diphasic when a shunt resistor is connected across the gap. This indicates that transmission between smoot...

The positive inotropic action of hexainethoniuin in hypodynamic and freshly prepared papillary muscles of the cat and the hypodynamic heart-lung preparation of the dog has been demonstrated. Within certain limits, there exists a proportionality between the concentration of hexamethonium and the magnitude of the inotropic response. In both preparations results have been obtained which indicate t...

The enzymic formation of sucrose from UDPGl and fructose has been described in the preceding paper (1). While some preparations of the enzyme were found to be almost devoid of action of fructose-6-phosphate, other extracts catalyzed the formation of free sucrose either from fructose or from its phosphate. Since these extracts contain phosphatase, it seemed likely that the action on fructose pho...

Primary progenitor tenocytes are diploid cells that may be cultured in vitro and therapeutically used for allogeneic musculoskeletal regenerative medicine. Firstly, technical aspects of cell banking, biotechnological manufacturing, extensive preclinical characterization data have confirmed FE002-Ten primary safely considered human cytotherapeutic use (e.g., tissue engineering products, standard...

The incorporation of thymidine in Novikoff hepatoma cells and Ehrlich ascites cells was severely and irreversibly inhibited by the polyenic antibiotics filipin and lucensomycin, known for their action on phospholipid-cholesterol membranes. No inhibition could be shown on regenerating liver cells or on acellular preparations from tumor cells. Despite the well-known site of action of these antibi...

This study explored the role of viable cells and active metabolites in seed-coating preparations living Streptomyces globisporus plant growth promotion disease control against Verticillium wilt cotton. Pot experiments were carried out to evaluate effects seed coating with (LA), inactivated (IA), 10-fold diluted (DLA) S. Act7 Act28 on performance index cotton seedlings under attack by dahliae. C...

Although the electrophysiological properties of intramural ventricular myocardial cells are important to an understanding of cardiac excitation and conduction, they have not been well defined. The paucity of information stems from limitations on the depth of penetration by glass microelectrodes and from difficulties in perfusing the deep layers. Therefore, a tissue slicing technique that satisf...

background: several compounds obtained from plants have potential insecticidal, growth deterrent or repellent characteristics. the control of hard ticks by non-chemical substances was targeted in this study. methods: the effect of 36 materials on in-vitro ticks was studied, including 2 absolute controls (water only or ab­solute ethyl alcohol only), 6 conventionally used spinosad preparations (a...

Moisturizers are one of the most widely used preparations in cosmetics and have been extensively to soften skin for consumers. work effectively combating dry which may cause pain, tightness, itch, stinging, and/or tingling. The aim this review is evaluate published studies on history, ingredients, preparation processes, characteristics, uses, applications moisturizers. bridge gap between medici...
