duced a systemic change in the animals that interfered with tumor rejection (12). The fact that these tumors were so highly antigenic suggested that host defense mechanisms may be of critical importance in the development of these skin cancers (4). There is a good possibility that our findings in the murine system on tumor antigenicity and the systemic immunological effects of UV treatment (4) ...

The implant osseointegration rate depends on the surface’s topography and chemical composition. There is a growing interest in the anodic oxidation process to obtain an oxide layer with a nanotube morphology on beta titanium alloys. This surface treatment presents large surface area, nanoscale rugosity and electrochemical properties that may increase the biocompatibility and osseointegration ra...

Virus-like particles (VLPs) with the full-length VP2 and VP6 rotavirus capsid proteins, produced in the baculovirus expression system, have been evaluated as surrogates of human rotavirus in different environmental scenarios. Green fluorescent protein-labeled VLPs (GFP-VLPs) and particles enclosing a heterologous RNA (pseudoviruses), whose stability may be monitored by flow cytometry and antige...

PURPOSE To investigate the lipid and DNA oxidative stress as well as corneal and retinal effects after ultraviolet B (UV-B) exposure in mice, with or without silicon hydrogel soft contact lenses (SCL). METHODS Twenty-eight C57BL6-strain male mice were divided into four groups: group I, control group with no SCL (SCL [-]) and no UV-B exposure (UV-B [-]); group II, senofilcon A SCL (senofilcon ...

cu-mo and cu-ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. the effects of process parameters such as film thickness, annealing duration and temperat...

Non-Langerhans cell, antigen-presenting T6- DR+ epidermal cells (EC) appear 3 days following broad band ultraviolet radiation exposure of human skin and are responsible for the increased antigen presentation capacity of EC seen 3 days after UV exposure. To determine the UV wavelengths that induce T6- DR+ EC, volar forearm skin of 10 human volunteers was irradiated in vivo with 4 minimal erythem...

With a view to improving the surface quality of magnesium (Mg) alloy at warm temperature, ultrasonic-assisted single-point incremental forming (SPIF) is proposed. The Mg during SPIF primarily affected by two parts: orange peel patterns non-contact and scratches adhesive wear contact surface. In this work, AZ31B sheet parts different temperatures ultrasonic amplitudes evaluated examining roughne...
