Finding new therapies for male and female pattern hair loss treatment remains as great interest. The autologous fat grafting technique is a new method, and clinical experience was increased over the past 10–15 years. Adipose tissue is a biologically active and important tissue and can help drive the complex hair growth cycle. Surgeons have previously reported that autologous fat not only have a positive affect for reconstructive volume and esthetics after transplant but can also have positive skin and hair changes post-transplantation. In this study, lipoaspiration of adipose was performed by cannula and scalp injection was done. In this case report, the authors report that scalp injection of adipose tissue has a positive effect on a patient with alopecia after trauma. The findings suggest adipose tissue can be a promising alternative method to treating men and women alopecia.

Drooping of the upper eyelid and eyebrow (ptosis) is common among people and cause the patients dissatisfaction. Various methods have been developed to treatment of the upper eyelid and eyebrow ptosis. However, the current methods focus on surgery to improve the disorder. But patients are worried about the risks of the procedure, and seeking for a non‐invasive alternative method. Therefore, non‐invasive methods with consistent efficient improvement are needed, especially for middle‐aged patients. This study was conducted of 9 patients who underwent the upper eyelid and eyebrow ptosis. Endolift laser method was used to treat the patients’ upper eyelid and eyebrow ptosis. The biometric assessment was used to evaluate the efficiency of the technique. Also the results were evaluated by 3 board‐certified dermatologists (blind). Additionally, patients’ satisfaction was evaluated at the end of the treatment. The biometric results showed that Endolift laser can increase the thickness, density, and elasticity of the skin in the eyelid area. The patient's satisfaction results showed excellent improvement in the 90% of patients. The results by the dermatologist displayed improvement in about 90% of patient. Endolift laser has been proved efficient and consistent for upper eyelid and eyebrow ptosis rejuvenation and treatment.

Electrical coupling has been reported to occur only between homotypic retinal ganglion cells, in line with the concept of parallel processing in the early visual system. Here, however, we show reciprocal correlated firing between heterotypic ganglion cells in multielectrode array recordings during light stimulation in retinas of adult guinea pigs of either sex. Heterotypic coupling was further confirmed via tracer spread after intracellular injections of single cells with neurobiotin. Both electrically coupled cell types were sustained ON center ganglion cells but showed distinct light response properties and receptive field sizes. We identified one of the involved cell types as sustained ON ␣-ganglion cells. The presence of electrical coupling between heterotypic ganglion cells introduces a network motif in which the signals of distinct ganglion cell types are partially mixed at the output stage of the retina.
