Background: Retinopathy of Prematurity (ROP) is a potentially blinding disorder that commonly afflicts premature infants who are born prior to 31weeks of gestation or with a body weight less than 1250 grams (about 2.75 pounds). Another risk factor is excessive oxygen in incubators, which can lead to blindness. A compounding factor is that survival rates for premature infants are rising with concomitantly more cases of ROP. We have reported an unsuspected intrinsic property of melanin to dissociate water. This capability can be considered an alternative treatment option for adult and neonatal diseases. It is known that exogenous surfactant administration suppresses bronchopulmonary dysplasia and consequent death, randomized, controlled trials with various respiratory interventions did not show any significant reductions in morbidity and mortality rates. During a descriptive study about the three leading causes of blindness in the world, the ability of melanin to transform light energy into chemical energy through the dissociation of water molecule was unraveled. Initially, during 2 or 3 years; we tried to link together our findings with the widely accepted metabolic pathways already described in molecular pathway databases, which have been developed to collect and organize the current knowledge on metabolism scattered across a multitude of scientific evidence.
Observations: The current report demonstrates the main problems that afflict premature babies with an emphasis on the growth of abnormal vessels in the retina, the explanation for which is unknown until date. We also reported a case of a baby who suffered digestive and respiratory problems with a brain haemorrhage that was successfully treated by laser photocoagulation. We hypothesise that most likely this effect was due to the melanin level and melanin itself produces oxygen via dissociating with water molecules.
Conclusion: We postulate that the intrinsic effect of melanin may easily convert visible and invisible light into chemical energy via a water dissociation reaction similar to the one in plant's chlorophyll, and markedly elevated with diagnosis and treatment of the complications related to premature babies.

Background: Although internet gaming disorder (IGD) has been included in the DSM-5 for approximately 10 years, debate remains regarding its existence and classification.
Methods: The current research incorporated three approaches. First, implicit association tests were used to examine for potential dissociation between wanting and liking in IGD.

Tyrosinase (Tyr) is a key enzyme in the process of melanin synthesis that occurs exclusively within specialized organelles called melanosomes in melanocytes. Tyr is synthesized and post-translationally modified independently of the formation of melanosome precursors and then transported to immature melanosomes by a series of membrane trafficking events that includes endoplasmic reticulum (ER)-to-Golgi transport, post-Golgi trafficking, and endosomal transport. Although several important regulators of Tyr transport have been identified, their precise role in each Tyr transport event is not fully understood, because Tyr is present in several melanocyte organelles under steady-state conditions, thereby precluding the possibility of determining where Tyr is being transported at any given moment.

The cAMP response element-binding protein (CREB) and CREB-regulated transcription coactivators (CRTCs) cooperate in the transcriptional activation of microphthalmia-associated transcription factor subtype M (MITF-M) that is a master regulator in the biogenesis, pigmentation and transfer of melanosomes at epidermal melanocytes. Here, we propose the targeting of phosphorylation circuits on CREB and CRTCs in the expression of MITF-M as the rationale to prevent skin hyperpigmentation by elucidating the inhibitory activity and mechanism of yakuchinone A (Yaku A) on facultative melanogenesis. We employed human epidermal melanocyte cell, mouse skin, and mouse melanoma cell, and applied Western blotting, reverse transcription-polymerase chain reaction, immunoprecipitation and confocal microscopy to conduct this study.

Rapid and sensitive antigen detection using a lateral flow immunoassay (LFIA) is crucial for diagnosing infectious diseases due to its simplicity, speed, and user-friendly features. However, it remains a critical issue to explore specific biorecognition elements and powerful signal amplification. In this study, taking SARS-CoV-2 as a proof of concept, a specific peptide, WFLNDSELIML, binding to the SARS-CoV-2 spike (S) antigen was identified by a nonamplified biopanning method, which exhibited high affinity to the target, with a dissociation constant of 9.
