Through selective activation/inhibition or dissection of neuronal circuits, optogenetic tools have raised hopes for a better understanding of neuropsychiatric mechanisms and therapeutic targets for various disorders. Although, overcoming serious limitations result in from conventional neuronal circuit study, this method has its own imperfections, such as optogenetic modulation of neural activity, using an internal, animal-generated, light source. In this review, limitations of external light delivery systems and possible approaches for using internal light sources in laboratory animals and perhaps, human being, are being addressed.

Eumelanin, a type of skin melanin pigment, possesses the ability to absorb a wide range of wavelengths, providing protection to the skin from ultraviolet radiation. However, excessive production of eumelanin may result in hyperpigmentation. Consequently, the development of skin-brightening products that suppress eumelanin synthesis to achieve a lighter and more even skin tone is necessary.

Triple-negative breast cancer (TNBC), defined by the lack of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression, is acknowledged as the most aggressive form of breast cancer (BC), comprising 15%-20% of all primary cases. Despite the prevalence of TNBC, effective and well-tolerated targeted therapies remain limited, with chemotherapy continuing to be the mainstay of treatment. However, the horizon is brightened by recent advancements in immunotherapy and antibody-drug conjugates (ADCs), which have garnered the U.

Age-related macular degeneration (AMD) is marked by a progressive loss of central vision and is the third leading cause of irreversible blindness worldwide. The exact mechanisms driving the progression of this macular degenerative condition remain elusive, and as of now, there are no available preventative measures for dry AMD. According to ancient records, ginseng affects the eyes by brightening them and enhancing wisdom.

The TNP-serum works synergistically by stimulating 9 key skin biomarkers to reduce wrinkles and produce a skin-brightening effect. Here, we highlight the real-life experiences of 5 dermatologists and 2 surgeons, using an integrated skincare regimen consisting of botulinum toxin type-A (BTX-A) injection in conjunction with twice daily TNP-serum.

The oculocutaneous albinism II () gene encodes a melanosomal transmembrane protein involved in melanogenesis. Recent genome-wide association studies have identified several single nucleotide polymorphisms within genes that are involved in skin pigmentation. Nevertheless, there have been no attempts to modulate this gene to improve skin discoloration.
