Hyperbilirubinemia results from the predisposition of newborns to produce bilirubin and their ability to excrete it. The treatment applied is phototherapy; however, one of its complications is degeneration of the retina by exposure to light, making it essential to provide proper eye protection. The objective of this study is to describe the development of an invention (utility model patented) for eye protection in newborn phototherapy. This invention aims to replace the current widespread practice of using improvised means that are uncomfortable for the baby and disrupt the mother/child relationship. A study was made of the radiances emitted by light sources used in phototherapy. The invention consists of an eye protector model for use during the newborn's phototherapy, allowing greater closeness between mother and baby. The device is easy to use, economical, removable and appropriate for newborns, causing no discomfort, and its effectiveness has been proved through radiance tests.

Noise-induced hearing loss (NIHL), caused by irreversible cochlear hair cell (HC) damage, lacks effective therapies due to a limited understanding of endogenous protective mechanisms. The echolocating bats exhibit natural resistance to intense noise, and this suggested novel insights into methods to protect against NIHL. Here, through comparative transcriptomic analysis of noise-exposed cochleae from the eastern bent-winged bats (Miniopterus fuliginosus) and mice, the specific transcriptional dynamics in noise-resistant Miniopterus fuliginosus are revealed, thus highlighting potential mechanisms for preventing cochlear damage that mouse models cannot replicate, with Hras emerging as the most significant hub upregulator.

The mucosal surfaces of the body are the most vulnerable points for infection because they are lined by single or multiple layers of very active epithelial cells. The main protector of these cells is the mucus system generated by the specialized goblet cell secreting its main components, the gel-forming mucins. The organization of the mucus varies from an attached mucus that is impenetrable to bacteria in the large intestine to a nonattached, more penetrable mucus in the small intestine.

Disturbance or insufficiency of the tear film challenges the regulatory systems of the ocular surfaces. The reaction of the surfaces includes temporary mechanisms engaged in the preservation of homeostasis. However, strong or persisting challenges can lead to the potential exhaustion of the coping capacity.

The harms caused by ultraviolet (UV) and blue light to eyes are attracting momentous concern due to growing exposure to artificial illumination and modern IT devices. Herein, a simple and eco-friendly adsorption approach was employed to integrate curcumin, a natural bioactive compound, into the cellulose substrate for the development of flexible and biodegradable filters capable of blocking harmful light. The curcumin/cellulose films demonstrate excellent UV-screening competence and photostability, with UV-A and UV-B screening ratios ranging from 92.
