Low-level laser therapy is applied externally through the skin of the patient to targeted areas of a of a patient's body to treat diabetes or prediabetes. A patient is first diagnosed with diabetes or prediabetes, preferably by blood draws that measure insulin, A1C, or glucose levels. A therapeutic amount of laser energy to apply is determined from a patient's biological factors such as body mass index. The therapeutic amount of laser energy is applied one or more times over a two week time period. The patient is then retested for diabetes or prediabetes. If necessary, a new therapeutic amount of laser energy is determined according to any changes in the patient's diabetes or prediabetes diagnosis and any changes in the patient's biological factors. Adjusted treatments with low-level laser energy continue until the diabetes or prediabetes diagnosis is removed.

The invention provides an energy source emitting, such as a low level laser light, catheter having a throughbore, an energy emitting surface disposed near the distal end of the catheter that is connected, directly or indirectly, to the energy source, which allows for the application of therapeutic energy to treat internal areas of a patient that have been accessed by way of a catheter.

A method of manufacturing a workpiece involves performing any one of various post-processing part modification steps on a workpiece that has been previously subjected to laser shock processing. In one step, material is removed from the compressive residual stress region of the processed workpiece. Alternately, the workpiece may be provided with oversized dimensions such that the removal process removes an amount of material sufficient to generate a processed workpiece having dimensions substantially conforming to design specifications. Alternately, the material removal process is adapted to establish a penetration depth for material removal that coincides with the depth at which the workpiece exhibits maximum compressive residual stress. Alternately, a first high-intensity laser shock processing treatment is performed on the workpiece, followed by the removal of material from the compressive residual stress region, and then a second low-intensity laser shock processing treatment is performed on the workpiece. Material may be removed from the compressive residual stress region through a workpiece surface different from the laser shock processed surface. Material may also be deposited onto the laser shock processed surface.

A portable, small-footprint laser device contains one or more housings in which a laser energy source and an optical arrangement are disposed. The housing produces a laser beam spot that may be rotated and scanned to apply laser energy to a target area. The laser device receives treatment parameters and uses them to program a treatment regimen in which activation and movement of the housings is automated. The laser device may be used to apply a treatment regimen to a patient's hands or feet that are infected by Onychomycosis. In the treatment regimen, certain wavelengths of laser energy are applied at a predetermined duration. The treatment may be repeated, and a topical anti-fungal medication may be applied to aid in the efficacy of the treatment.

The invention relates to a polarized light scattering measurement system and method based on magneto-optic modulation. Coherent light sent out by a laser is changed to linear polarized light through a polarizer, and the linear polarized light is focused into a sample matching tank through a focusing lens. Scattered light coming out from the sample matching tank passes through an expanded beam collimating lens to reduce a divergence angle of the scattered light and collimate the diameter of an outgoing beam, and then the scattered light passes through a Faraday coil, a polarization analyzer and an expanded beam lens in sequence to obtain linear polarized light with periodic changes which can be received by a photomultiplier tube after passing through an aperture diaphragm capable of limiting a photosensitive area, signals are sent into a phase-locked amplifier by the photomultiplier tube to filter and remove external noise and white noise inside equipment, and then sent into a sampling integrator and a computer for sampling integration and digital average to obtain the particle size distribution. Compared with the prior art, the polarized light scattering measurement system and method based on the magneto-optic modulation can be used for low-intensity laser measurement without interference or damage to a sample, can be used for quickly and accurately measuring the nanoparticle size, suppressing the noise to the maximum extent and improving the measurement accuracy to enable the system to be suitable to be used in various environments.

A method of increasing bone marrow stem cells in the blood stream, and targeting those stem cells toward specific damaged or diseased organs in the body so that the tissue in these organs might be repaired. The method comprises ingestion of a claimed formulation having effective amounts of Aphanizomenon flos-aquae and fucoidan being released into the blood stream over a measured period of time, and during that period, irradiating the ribs, skull, vertebrae, or pelvic bones, as well as the damaged or diseased area with low-level laser therapy. The combination of ingesting the formulation and the low-level laser therapy causes the release of bone marrow pluripotent stem cells, which then transform into the targeted tissue cells, thereby repairing the damaged or diseased tissue.

Deep Tissue Low Intensity Laser Therapy or Treatment (DT-LILT) as described here is a novel methodology through which selective destruction of nociceptive (pain) nerves can be brought upon by a medical laser delivery system using the phenomenon of absorption and cell resonance. Using this method nerve cells that transmit pain can be selectively destroyed leaving the surrounding tissues intact as no heat is generated. The delivery system incorporates a fine needle through which a 703 nm (range 690 to 710) pulsed wave low intensity laser is delivered deep into the body, directly to the area of pain causing selective destruction of pain nerves. Laser devices based on this methodology should be used only by the physician or equivalent professional community since diagnosing and defining the area of pain is critical to providing successful pain relief.
