Myofascial pain syndrome (MPS) is characterized by chronic pain in multiple myofascial trigger points and fascial constrictions. In recent years, the scientific literature has recognized the need to include the patient with MPS in a multidimensional rehabilitation project. At the moment, the most widely recognized therapeutic methods for the treatment of myofascial syndrome include the stretch and spray pressure massage. Microcurrent electric neuromuscular stimulation was proposed in pain management for its effects on normalizing bioelectricity of cells and for its sub-sensory application...

The authors for the first time provide the scientifically-grounded substantiation for the application of electrical stimulation with bipolar pulsed currents for the combined treatment of the patents presenting with acne vulgaris. Experiments on the rabbits have demonstrated the influence of bipolar pulsed currents on the cellular composition of lymph nodes and thereby facilitated the better understanding of certain theoretical aspects of the application of electrical stimulation at large. The clinical study on the application of multi-channel electrical stimulation and microcurrent therapy showed that these physical factors may cause remodeling of immunogenesis in the patents presenting with acne vulgaris manifested as the normalization of the cellular composition of peripheral blood (leukocyte, lymphocyte, T- and B-lymphocyte counts and immunoglobulin levels)...

CONTEXT: Eye conditions that are considered progressive and degenerative and for which the causation is generally poorly understood or not understood within conventional medicine can respond to natural therapeutic interventions that result in arrest and/or improvement of morbidity, with enhanced functional results. Because many of the treated conditions are age related, a delay of disease progression for 5 or even 10 y can mean an additional decade of independence for seniors. The 11 included ocular conditions are ordinarily considered incurable by any method except surgery and, even with surgery, the outcomes can be variable and/or transient...

In this work, dendritelike and rodlike NiCu alloys were prepared by a one-pot hydrothermal process at various reaction temperatures (120, 140, and 160 °C). The structure and morphology were analyzed by scanning electron microscopy, energy-dispersive spectrometry, X-ray diffraction, and transmission electron microscopy, which that demonstrate NiCu alloys have core-shell heterostructures with Ni as the shell and Cu as the core. The formation mechanism of the core-shell structures was also discussed. The uniform and perfect dendritelike NiCu alloy obtained at 140 °C shows outstanding electromagnetic-wave absorption properties...

Conservative therapies, mainly resting care for the damaged muscle, are generally used as a treatment for skeletal muscle injuries (such as muscle fragmentation). Several past studies reported that microcurrent electrical neuromuscular stimulation (MENS) facilitates a repair of injured soft tissues and shortens the recovery period. However, the effects of MENS on the regeneration in injured skeletal muscle are still unclear. The purpose of this study was to investigate the effect of MENS on the regenerative process of injured skeletal muscle and to elucidate whether satellite cells in injured skeletal muscle are activated by MENS by using animal models...
