Objectives: To determine the behavior of the visual cerebral cortex during the photo stimulation in the dissociated strabismus.
Material And Methods: We elaborated a digital cerebral mapping using the international 10-20 system with 21 electrodes and an option of a register of 32 channels with established parameters in every period (printed and with pulse monitoring) applied to two children with dissociated strabismus. We registered and evaluated the cortical response to different stimuli: luminous, hyperventilation, closing and opening of eyelids, asleep and awake; through digital electroencephalography, as well as the registering of ocular movements with electroculography and video film with infrared light.
Results: We discovered a paradoxical neuroelectrical response and the visual cerebral cortex during the intermittent photo stimulation never reported before, showing the neuroelectrical changes that occur in the dissociated horizontal deviation (DHD). We correlated these findings with the origin of the dissociated strabismus.

In-situ tumor vaccination remains challenging due to difficulties in the exposure and presentation of tumor-associated neoantigens (TANs). In view of the central role of lipid metabolism in cell fate determination and tumor-immune cell communication, here we report a photo-controlled lipid metabolism nanoregulator (PLMN) to achieve robust in-situ adjuvant-free vaccination, which is constructed through hierarchically integrating photothermal-inducible arachidonate 15-lipoxygenase (ALOX15)-expressing plasmids, cypate and FIN56 into cationic liposomes. Near-infrared light (NIR) stimulation triggers on-demand ALOX15 editing and causes excessive accumulation of downstream pro-ferroptosis lipid metabolites.

Purpose: Photo-immunotherapy faces challenges from poor immunogenicity and low response rate due to hypoxic microenvironment. This study presents Rh-PTZ, a small organic molecule with a D-π-A structure, that simultaneously amplifies mitochondria-targeted type-I PDT-dependent immune stimulation for the treatment of hypoxic cancer.
Methods: The hydrophobic Rh-PTZ was encapsulated into F127 to prepare Rh-PTZ nanoparticles (Rh-PTZ NPs).

A single-component flavin-dependent halogenase, AetF, has emerged as an attractive biocatalyst for catalyzing halogenation. However, its flavin chemistry remains unexplored and cannot be predicted due to its uniqueness in sequence and structure compared to other flavin-dependent monooxygenases. Here, we investigated the flavin reactions of AetF using transient kinetics.

New concepts to treat eye diseases have emerged that elegantly combine unnatural light exposure with chemical biology approaches to achieve superior cellular specificity and, as a result, improvement of visual function. Historically, light exposure without further molecular eye treatment has offered limited success including photocoagulation to halt pathological blood vessel growth or low light exposure to stimulate retinal cell viability. To add cellular specificity to such treatments, researchers have introduced various biological or chemical light-sensing molecules and combined those with light exposure.

Cigarette filter microplastics are composed of cellulose acetate that does not undergo biological or photo-degradation. These microplastics are readily dispersed and can be found abundantly in water, soil, and air. These fibers possess high absorption capabilities, allowing them to collect and retain pollutants such as toxic elements.
