Abstract
Hexagrammos otakii is favored by consumers and aquaculture practitioners because of its strong adaptability and fast growth. However, recently, frequent outbreaks of diseases in the breeding of H. otakii have led to significant economic losses, especially due to bacterial diseases, which limit the healthy breeding of H. otakii. As a luminescent Gram-negative bacterium, Vibrio harveyi is the main pathogenic bacteria of H. otakii. In this study, the histopathology and label-free quantitative proteomics analysis were performed to reveal the changes of skin mucus proteins in H. otakii after infection with V. harveyi. The histopathological changes in the skin of H. otakii showed that when the bacteria were injected into the epithelial cells, it caused an increase in the number of mucous cells and a certain degree of damage and deformation in skin. Moreover, the quantitative proteomics analysis revealed a total of 364 differentially expressed proteins (DEPs), and these DEPs were found to be involved in environmental information processing, metabolism, infectious diseases: bacteria, replication and repair. More importantly, the enrichment analysis of the DEPs revealed that these different proteins were mainly targeted immune-related pathways. After infection of bacteria, the host's immune ability will be weakened, causing V. harveyi to enter the organism more easily, resulting in increased mucus in H. otakii, which will eventually lead to a decline in its physical function. These results provided an insight into a series of physiological changes after the bacterial infection of fish at the proteomic level and basic data for further exploration of the potential mechanism of skin mucus. Taken together, the results indicated more opportunities for the future designs and discoveries of effective antibacterial vaccines and antibacterial drugs for H. otakii.

Abstract
Polydopamine (PDA), the synthetic counterpart of melanin, is a widely investigated bio-inspired material for its chemical and photophysical properties, and in the last few years, bio-application of PDA and PDA-based materials have had a dramatic increase. In this review, we described PDA application in optical biosensing, exploring its multiple roles as a nanomaterial. In optical sensing, PDA can not only be used for its intrinsic fluorescent and photoacoustic properties as a probe: in some cases, a sample optical signal can be derived by melanin generation in situ or it can be enhanced in another material thanks to PDA modification. The various possibilities of PDA use coupled with its biocompatibility will indeed widen even more its application in optical bioimaging.

Abstract
Agriculture plays a pivotal role in food security and food security is challenged by pests and pathogens. Due to these challenges, the yields and quality of agricultural production are reduced and, in response, restrictions in the trade of plant products are applied. Governments have collaborated to establish robust phytosanitary measures, promote disease surveillance, and invest in research and development to mitigate the impact on food security. Classic as well as modernized tools for disease diagnosis and pathogen surveillance do exist, but most of these are time-consuming, laborious, or are less sensitive. To that end, we propose the innovative application of a hybrid imaging approach through the combination of confocal fluorescence and optoacoustic imaging microscopy. This has allowed us to non-destructively detect the physiological changes that occur in plant tissues as a result of a pathogen-induced interaction well before visual symptoms occur. When broccoli leaves were artificially infected with Xanthomonas campestris pv. campestris (Xcc), eventually causing an economically important bacterial disease, the induced optical absorption alterations could be detected at very early stages of infection. Therefore, this innovative microscopy approach was positively utilized to detect the disease caused by a plant pathogen, showing that it can also be employed to detect quarantine pathogens such as Xylella fastidiosa.

Interactions of ultrashort laser pulses with hemoglobin: Photophysical aspects and potential applications. Int J Biol Macromol 2023:125312.

Abstract
Hemoglobin (Hb), a life-sustaining and highly abundant erythrocyte protein, is not readily fluorescent. A few studies have already reported Two-Photon Excited Fluorescence (TPEF) of Hb, however, the mechanisms through which Hb becomes fluorescent upon interaction with ultrashort laser pulses are not completely understood. Here, we characterized photophysically this interaction on Hb thin film and erythrocytes using fluorescence spectroscopy upon single-photon/two-photon absorption, and UV-VIS single-photon absorption spectroscopy. A gradual increase of the fluorescence intensity, ending up with saturation, is observed upon prolonged exposure of Hb thin layer and erythrocytes to ultrashort laser pulses at 730 nm. When compared to protoporphyrin IX (PpIX) and oxidized Hb by H2O2, TPEF spectra from a thin Hb film and erythrocytes showed good mutual agreement, broad peaking at 550 nm, supporting hemoglobin undergoes degradation and that same fluorescent specie(s) originating from the heme moiety are generated. The uniform square shaped patterns of the fluorescent photoproduct exhibited the same level of the fluorescence intensity even after 12 weeks from the formation, indicating high photoproduct stability. We finally demonstrated the full potential of the formed Hb photoproduct with TPEF scanning microscopy towards spatiotemporally controlled micropatterning in HTF and single human erythrocyte labelling and tracking in the whole blood.
