Coatings prepared from nanosized powders were obtained by spraying ethanol-based colloidal solutions into a plasma plume. The powders investigated included 40 nm γ -Al2O3, 75 nm 8 wt% Y2O3-ZrO2, and 750 nm 25 wt% CeO2-ZrO2. Spray distances from approximately 50 to 63 mm were required to achieve significant coating deposition. As observed in the TEM, the typical lamella morphology of air plasma ...

The quantitative relationship between change in cell shape and ATP consumption is an unsolved problem in cell biology. In this study, a simultaneous imaging and image processing analysis allowed us to observe and quantify these relationships under physiological conditions, for the first time. We focused on two marginal regions of cells: the microtubule-rich 'lamella' and the actin-rich 'periphe...

Abstract At present, there are increasingly encountering the use of lamellar structures, for example on roofs buildings, which, in addition to their visual function, also fulfil function reducing flow wind into roof space. These structures often designed as long and subtle therefore very common problem is unwanted vibration. In this article, main focus show methodology determination effects lam...

Laminin-5 is a major adhesion protein of the skin basement membrane and crucially involved in integrin-mediated cell substrate attachment of keratinocytes, which is important for hemidesmosomal anchorage as well as for keratinocyte migration during epidermal wound healing. To investigate its role in keratinocyte migration, we analyzed laminin-5-deficient cells of patients with a lethal variant ...

This paper proposes a multi-level hierarchical model for the Tokay gecko (Gekko gecko) adhesive system and analyses the digital behaviour of the G. gecko under macro/meso-level scale. The model describes the structures of G. gecko’s adhesive system from the nano-level spatulae to the sub-millimetre-level lamella. The G. gecko’s seta is modelled using inextensible fibril based on Euler’s elastic...

Ultrastructural changes in the cell walls of "Calville de San Sauveur" apples (Malus sylvestris Mill) and "Spadona" pear (Pyrus communis L.) fruit were followed during ripening. In apple, structural alterations in cell walls became apparent at advanced stages of softening and showed predominantly dissolution of the middle lamella. In pears softening was also associated with the dissolution of t...

BACKGROUND Natural adhesion between the levator aponeurosis and the subcutaneous layer in the upper lid is essential for an aesthetically pleasing double eyelid. The study aims to emphasize the outer fascia of orbicularis oculi muscle (OFOOM) as a fixation point on the double eyelid surgery. METHODS The authors examined the detailed anatomy of the anterior lamella microscopically during 28 ca...

PURPOSE To evaluate the outcomes of the hybrid technique of posterior lamellar keratoplasty (DMEK-S). MATERIALS AND METHODS 71 eyes of 55 patients enrolled in a single-center study underwent posterior lamellar keratoplasty with a hybrid lamella DMEK-S implanted using a solution implantation technique, owing to endothelial dysfunction. The outcome measures studied were visual acuity and endoth...
