BACKGROUND Although several studies have demonstrated the effects of low-level laser therapy (LLLT) on skin flap viability, the role of higher doses has been poorly investigated. OBJECTIVE To investigate the inhibitory effect of the LLLT (λ=670 nm) on the viability of random skin flaps in a rat model using an irradiation energy of 2.79 J at each point. METHODS Sixteen Wistar rats were rando...

there is just one study about the effects of 830 nm low power laser (lpl) on conduction velocity of sural nerve in human. considering the fact that the sural nerve is a pure sensory nerve, therefore, for determining the effect of lpl on electrophysiological parameters of the nerve in human, this study was carried out as a base for further basic and clinical researches. thirty eight normal volun...

Mineral physics observations suggest that distinct density and rheological differences exist between the crustal component of oceanic lithosphere and the underlying mantle. We have conducted numerical experiments to investigate the influence of both density and viscosity on the effectiveness of recycling of oceanic crust into the lower mantle. Confirming previous results, the density inversion ...

BubR1 is a central component of the spindle assembly checkpoint that inhibits progression into anaphase in response to improper kinetochore-microtubule interactions. In addition, BubR1 also helps stabilize kinetochore-microtubule interactions by counteracting the Aurora B kinase but the mechanism behind this is not clear. Here we show that BubR1 directly binds to the B56 family of protein phosp...

Data are presented demonstrating the differential radiosensitivity of the first and second-set responses of sublethally irradiated (670 rad) mice previously sensitized with allogeneic (H-2 difference), xenogeneic (rat) or both allogeneic and xenogeneic skin grafts: The secondset response is more radioresistant than is the first-set response; the second-set response to a xenogeneic graft remains...

In a previous paper we described details of the construction of stabilized 670-nm diode lasers for use in undergraduate physics laboratories. We report here a series of experiments that can be performed using the 670-nm diode laser, a homemade scanning Fabry-Perot cavity, a helium-neon laser, a simple photodiode, and a few pieces of electronics hardware. The experiments include: 1) an introduct...

The purpose of this study is to identify any association between malnutrition and morbid obesity and determine if either independently increases complications following primary total joint arthroplasty (TJA). The study retrospectively reviewed a series of 670 patients who underwent primary TJA at a single institution. Patients were categorized as malnourished if their preoperative serum albumin...

The spatial and color coding of the monophasic horizontal cells were studied in light- and dark-adapted retinae. Slit displacement experiments revealed differences in integration area for the different cone inputs of the monophasic horizontal cells. The integration area measured with a 670-nm stimulus was larger than that measured with a 570-nm stimulus. Experiments in which the diameter of the...
