Abstract
The impact of curcumin-mediated photodynamic treatment (PDT) on the microbiological, physicochemical and sensory qualities of salmon sashimi has not been explored. Herein, this study aimed to evaluate the effects of PDT on the shelf-life quality of ready-to-eat salmon fillets during chilled storage (4 °C) in comparison with five widely investigated natural extracts, including cinnamic aldehyde, rosmarinic acid, chlorogenic acid, dihydromyricetin and nisin. From a microbial perspective, PDT exhibited outstanding bacterial inhibition, the results of total viable counts, total coliform bacteria, psychrotrophic bacteria, Pseudomonas spp., Enterobacteriaceae family, and H2S-producing bacteria were notably inactivated (p < 0.05) to meet the acceptable limits by PDT in comparison with those of the control group and natural origin groups, which could extend the shelf-life of salmon fillets from<6 days to 10 days. In the alteration of physicochemical indicators, PDT and natural extracts were able to maintain the pH value and retard lipid oxidation in salmon fillets, while apparently slowing the accumulation (p < 0.05) of total volatile basic nitrogen and biogenic amines, especially the allergen histamine, which contrary to with the variation trend of spoilage microbiota. In parallel, PDT worked effectively (p < 0.05) on the breakdown of adenosine triphosphate and adenosine diphosphate to maintain salmon fillet freshness. Additionally, the physical indicators of texture profile and color did not have obvious changes (p < 0.05) after treated by PDT during the shelf life. Besides, the sensory scores of salmon samples were also significantly improved. In general, PDT not only has a positive effect on organoleptic indicators but is also a potential antimicrobial strategy for improving the quality of salmon sashimi.

Abstract
BACKGROUND Acinetobacter baumannii is a Gram-negative, non-fermenting coccobacillus of the Moraxellaceae family. It is an opportunistic pathogen responsible for several hospital-acquired infections (HAIs) associated with skin and tissue infections at surgical sites, catheter-associated urinary tract infections, and central line catheters. Multidrug-resistant (MDR) A. baumannii has caused hospital outbreaks that are difficult to eradicate and represent one of the leading producers of HAIs. MDR-A. baumannii presents a broad range of resistance to different antimicrobials, including carbapenems. Due to the low sensitivity to conventional antibiotic therapies, it is necessary to identify other therapeutic options. Antimicrobial photodynamic therapy (aPDT) is a promising alternative and complementary approach to address the shortage of antimicrobials in MDR-A. baumannii. APDT combines a photosensitizer agent, light, and oxygen to achieve a bactericidal/bacteriostatic effect. The effect is given by producing reactive oxygen species (ROS) that produce photooxidative stress over bacterial structures, such as the envelope and the DNA. METHODS This study aims to systematically collect bibliographic information from databases such as PubMed, Scopus, and google scholar to analyze the relevant articles critically. RESULTS An increasing body of evidence demonstrates the efficacy of photodynamic inactivation in eliminating A. baumannii strains, both in vitro and in vivo. CONCLUSIONS The evidence supports that photodynamic inactivation is an alternative capable of eliminating strains of Acinetobacter baumannii and may considerably improve the treatment of MDR strains. Although they do exist, aPDT studies on MDR strains of A. baumannii are scarce and should increase since it is on these strains that photodynamic therapy becomes attractive.

Abstract
Photodynamic therapy (PDT) induces immunogenic cell death (ICD) by producing reactive oxygen species (ROS), making it an ideal method for cancer treatment. However, the extremely lower level of oxygen, short half-life of produced ROS, and limited photosensitizers accumulating in the tumor site via intravenous administration are the main reasons that limit the further application of PDT. To address these issues, we loaded the photosensitizer porphine (THPP) into biomimetic gold nanorod-mesoporous silica core-shell nanoparticles (Au-MSN NPs) to prepare Au@MSN/THPP@CM NPs. We then seeded the NPs together with catalase (CAT) into a gelatin methacryloyl (GelMA) microgel matrix to form Au@MSN-Ter/THPP@CM@GelMA/CAT microspheres consisting of biomimetic nano@microgel. The NPs and biomimetic nano@microgel exhibited enhanced photodynamic (PD) reaction and excellent photothermal conversion ability. Moreover, we further conjugated an endoplasmic reticulum (ER) targeting ligand Tosyl Ethylenediamine (Ter) on the surface of Au-MSN NPs. The results showed that both Au@MSN-Ter/THPP@CM NPs and the finally formed Au@MSN-Ter/THPP@CM@GelMA/CAT biomimetic nano@microgel induced precise and prolonged ER stress through photodynamic reactions, which stimulated the exposure of the proapoptotic calreticulin (CRT) on the cell membrane and increased the release of high mobility group box 1 (HMGB1) form the nucleus in SKOV3 cells under near-infrared (NIR) laser irradiation. Additionally, a single dose of the nano@microgel delivered through minimally invasive injection generated a significant anti-tumor effect in the SKOV3 cell line-derived orthotopic ovarian cancer mouse model through a PD and PT combination therapy. This study offers a new strategy for enhanced PDT and provides a PD/PT synergistic treatment method for ovarian cancer.

Abstract
Chromoblastomycosis is a fungal disease presented with local warty papule, plaque, and verrucous nodules. In addition, the incidence and drug resistance of chromoblastomycosis are increasing each year worldwide. Photodynamic therapy is a promising method to treat mycoses. The purpose of this study was to evaluate the effect of new methylene blue (NMB)-induced PDT on multidrug-resistant chromoblastomycosis in vitro. We isolated one wild-type strain pathogen from one clinical patient diagnosed with chromoblastomycosis for over 27 years. The pathogen was identified by histopathology, the morphology of fungal culture, and genetic testing. Drug susceptibility testing was performed on the isolate. It was cultured with logarithmic growth phase spore in vitro and incubated with different concentrations of NMB for 30 min, and received illumination by red light-emitted diode with different light doses. After photodynamic treatment, the scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were conducted. The pathogen was Fonsecaea nubica, and it was resistant to itraconazole, terbinafine, amphotericin B, voriconazole andcaspofungin. At the same NMB concentration, the sterilization efficiency of NMB-photodynamic therapy (PDT) on F. nubica increased with increasing light intensity; F. nubica was completely killed at 25 µmol/L NMB with a light dose of 40 J/cm2 or 50 µmol/L NMB and light doses of ≥ 30 J/cm2. SEM and TEM observed ultrastructural changes after PDT. NMB-PDT inactivates the survival of multidrug-resistant F. nubica in vitro; it therefore has the potential to become an alternative or adjuvant treatment for refractory chromoblastomycosis.

Abstract
Metal-organic frameworks (MOFs) are porous, crystalline materials made up of organic ligands and metal ions/metal clusters linked by coordinative bonds. This large family is becoming increasingly popular for drug delivery due to their tuneable porosity, chemical composition, size and shape, and ease of surface functionalization. There has been a growing interest over the last decades in the design of engineered MOFs with controlled sizes for a variety of biomedical applications. Starting with the MOFs classification adapted for drug delivery systems (DDSs) based on the types of constituting metals and ligands. MOFs are appealing drug delivery vehicles because of their substantial drug absorption capacity and slow-release processes, which protect and convey sensitive drug molecules to target areas. Other guest materials have been incorporated into MOFs to create MOF-composite materials, which have added additional functionalities such as externally triggered drug release, improved pharmacokinetics, and diagnostic aids. Magnetic nanoparticles in MOFs for MRI image contrast and polymer coatings that increase blood circulation time are examples of synthetically adaptable MOF-composites. By including photosensitizers, which exert lethal effects on cancer cells by converting tumour oxygen into reactive singlet oxygen (1O2), metal-organic frameworks have been employed for photodynamic treatment (PDT) of malignancies among a multitude of nanosized therapies. Importantly, a variety of representative MOF applications are described from the perspectives of pharmaceutics, disease therapy, and advanced drug delivery systems. However, because of their weak conductivity, selectivity, and lack of modification sites, MOF materials' uses in electrochemical biosensing are restricted. MOF-based composites provide excellent electrical conductivity and robust catalytic activity by adding functionalized nanoparticles into MOF structures, which process benefits over single component MOFs.

Abstract
Interest in using an antimicrobial photodynamic treatment (aPDT) for the microbial decontamination of food has been growing. In this study, quercetin, a substance found ubiquitously in plants, was used as a novel exogenous photosensitizer with 405 nm blue light (BL) for the aPDT on foodborne pathogens, and the inactivation mechanism was elucidated. The inactivation of Escherichia coli O157:H7 and Listeria monocytogenes in PBS solution by the quercetin and BL combination treatment reached a log reduction of 6.2 and more than 7.55 at 80 J/cm2 (68 min 21 s), respectively. When EDTA was added to investigate the reason for different resistance between two bacteria, the effect of aPDT was enhanced against E. coli O157:H7 but not L. monocytogenes. This result indicated that the lipopolysaccharide of Gram-negative bacteria operated as a protective barrier. It was experimentally demonstrated that quercetin generated the superoxide anion and hydrogen peroxide as the reactive oxygen species that oxidize and inactivate cell components. The damage to the bacterial cell membrane by aPDT was evaluated by propidium iodide, where the membrane integrity significantly (P < 0.05) decreased from 40 J/cm2 compared to control. In addition, DNA integrity of bacteria was significantly (P < 0.05) more decreased after aPDT than BL treatment. The inactivation results could be applied in liquid food industries for decontamination of foodborne pathogens, and the mechanisms data was potentially utilized for further studies about aPDT using quercetin.

Abstract
In this paper we compare the response of cells of established lines of different origin: HeLa, A549 and 3T3 to photodynamic treatment with Radachlorin photosensitizer. The analysis was performed on different aspects of the treatment procedure including photosensitizer accumulation, localization and photobleaching in cells and post-treatment dynamics of changes in cellular morphology at different treatment doses. It was shown that in the three cell lines Radachlorin accumulated in lysosomes to much greater extent than in mitochondria. The cells' response to treatment was analyzed by identification of their death pathways and evaluation of average phase shift dynamics using digital holographic microscopy. The analysis performed on the three cell lines allowed us to evaluate treatment doses specific for each pathway in each line. Among the three lines HeLa cells were found to be the most susceptible to treatment while 3T3 cells the most resistant. The comparison of these results with the data on Radachlorin accumulation, localization and photobleaching rates showed that the observed higher sensitivity of HeLa cells to photodynamic treatment correlated with higher photosensitizer uptake and more intensive photobleaching while lower sensitivity of 3T3 cells correlated with lower uptake and less intensive photobleaching.

Abstract
The widespread use of conventional chemical antifungal agents has led to worldwide concern regarding the selection of resistant isolates. In this scenario, antimicrobial photodynamic treatment (APDT) has emerged as a promising alternative to overcome this issue. The technique is based on the use of a photosensitizer (PS) and light in the presence of molecular oxygen. Under these conditions, the PS generates reactive oxygen species which damage the biomolecules of the target organism leading to cell death. The great potential of APDT against plant-pathogenic fungi has already been reported both in vitro and in planta, indicating this control measure has the potential to be widely used in crop plants. However, there is a lack of studies on environmental risk with ecotoxicological assessment of PSs used in APDT. Therefore, this study aimed to evaluate the environmental toxicity of four phenothiazinium PSs: i) methylene blue (MB), ii) new methylene blue N (NMBN), iii) toluidine blue O (TBO), and iv) dimethylmethylene blue (DMMB) and also of the commercial antifungal NATIVO®, a mixture of trifloxystrobin and tebuconazole. The experiments were performed with Daphnia similis neonates and zebrafish embryos. Our results showed that the PSs tested had different levels of toxicity, with MB being the less toxic and DMMB being the most. Nonetheless, the environmental toxicity of these PSs were lower when compared to that of NATIVO®. Furthermore, estimates of bioconcentration and of biotransformation half-life indicated that the PSs are environmentally safer than NATIVO®. Taken together, our results show that the toxicity associated with phenothiazinium PSs would not constitute an impediment to their use in APDT. Therefore, APDT is a promising approach to control plant-pathogenic fungi with reduced risk for selecting resistant isolates and lower environmental impacts when compared to commonly used antifungal agents.

Abstract
A 10-year-old canine with chronic unilateral otitis and a history of unsuccessful systemic and topical antibiotic treatments was referred. A computer tomography scan (CT scan) revealed unilateral chronic otitis with calcification of the ear canal, abscessation and fistula. On bacterial culture a Staphylococcus pseudintermedius sensitive to pradofloxacin was isolated. Systemic treatment with pradofloxacin, 3 mg/kg per os once daily, improved the infection and the dog had total ear canal ablation and bulla osteotomy performed. After one month, despite antibiotic treatment new fistulas developed in the same area. Bacterial culture revealed an drug-resistant S. pseudintermedius sensitive only to rifampicin. Under general anesthesia, the area was cleaned with 0.5% saline solution and 1 mL of indocyanine green (Emundo®, A.R.C.) was injected into the fistulas. A treatment with diode laser (A.R.C. Laser 810 nm, GmbH, Nurnberg, Germany) of four cycles 500 mw for 30 s, with a dosage of 50 J/cm2 in the effected area was performed. No antibiotic was administered and one week later, 50% of the fistulas were closed with a significant improvement of the patient's clinical condition. Cytology and bacterial culture were negative 72 h after the treatment. Total recovery occurred after two weeks. Photodynamic Therapy(PDT) is a promising antibacterial technique in case of localized refractory bacterial infections.

Abstract
The investigation of in-vitro response of cell cultures derived from tumor material of individual patients with similar tumor localizations to photodynamic treatment is presented. Tumor types included in the research were renal cell carcinoma, melanoma and alveolar, synovial, lypo- and osteo- sarcomas. Long-term observations of treatment-induced morphological changes in cells were performed by means of digital holographic microscopy. A substantial variance in response of cells of individual patients with similar tumor types and localizations to photodynamic treatment with the same dose has been observed. These peculiarities are indicative of the demand to personalized protocols of photodynamic treatment. The elevated resistance of cells of some patients to treatment at high doses highlights potential limitations of photodynamic therapy for some patients. Digital holographic microscopy is shown to be an informative label-free noninvasive tool allowing for long-term monitoring of cell samples in vitro and providing quantitative information on necrosis rate and loss of cellular dry mass. The developed methodology can be generalized for analysis of cellular response to various therapies.

Abstract
This study evaluated the feasibility of curcumin based photodynamic sterilization technology (PDT) applied to fresh-cut potato slices. Potato samples with 30 μmol L-1 curcumin solution were exposed to 420 nm light emitting diodes (LED) at a total dose of 0.7 kJ cm-2. Results showed that PDT inactivated 2.43 log CFU mL-1 of Escherichia coli (BL 21) and 3.18 log CFU mL-1 of Staphylococcus aureus and maintained the color, texture, weight as well as total solid content of treated potatoes. Additionally, loss of phenols and flavonoids was significantly prevented, increasing the total antioxidant capacity. This was attributed to changes in enzyme activity that PDT decreased the activity of polyphenol oxidase (PPO) and peroxidase (POD) by 59.7% and 47.8% and increased the activity of phenylalanine ammonia-lyase (PAL). Therefore, curcumin-based PDT has the potential to maintain the commercial quality of producing and achieving microbiological safety.

Abstract
Photodynamic therapy (PDT) is based on the production of the cytotoxic reactive oxygen species (ROS) by light irradiation of a photosensitizer dye in the presence of molecular oxygen. Along with photochemical ROS production, it becomes evident that PDT induces massive secondary production of ROS which is registered long after the irradiation is completed. We created cell lines of human epidermoid carcinoma with the cytoplasmic and mitochondrial localization of protein sensor HyPer sensitive to hydrogen peroxide to compare its concentration in two cellular compartments. The lag-period between irradiation and accumulation of hydrogen peroxide in cells was registered; its duration was dose-dependent and increased up to 80 min when lowering the exposition dose from 50 to 15 J/cm2. We have shown that localization of the photosensitizer determines the spatiotemporal pattern of the cell response to PDT: secondary hydrogen peroxide accumulation in cell cytoplasm induced by photodynamic treatment with lysosome-localized phtalocyianine Photosens occurs several minutes prior to that in mitochondria; on the contrary, membranotropic arylcyanoporphyrazine dye leads to massive mitochondrial hydrogen peroxide production followed by its cytoplasmic accumulation. We hypothesize that photosensitizers with various physicochemical properties and intracellular localization can trigger different patterns not only of primary but also secondary ROS production leading to different cell fate outcomes.

Abstract
Photodynamic therapy is an attractive technique for various skin tumors and non-cancerous skin lesions. However, while the aim of photodynamic therapy is to target and damage only the malignant cells, it unavoidably affects some of the healthy cells surrounding the tumor as well. However, data on the effects of PDT to normal cells are scarce, and the characterization of the pathways activated after the photodamage of normal cells may help to improve clinical photodynamic therapy. In our study, primary human epidermal keratinocytes were used to evaluate photodynamic treatment effects of photosensitizers with different subcellular localization. We compared the response of keratinocytes to lysosomal photodamage induced by phthalocyanines, aluminum phthalocyanine disulfonate (AlPcS2a) or aluminum phthalocyanine tetrasulfonate (AlPcS4), and cellular membrane photodamage by m-tetra(3-hydroxyphenyl)-chlorin (mTHPC). Our data showed that mTHPC-PDT promoted autophagic flux, whereas lysosomal photodamage induced by aluminum phthalocyanines evoked differentiation and apoptosis. Photodamage by AlPcS2a, which is targeted to lysosomal membranes, induced keratinocyte differentiation and apoptosis more efficiently than AlPcS4, which is targeted to lysosomal lumen. Computational analysis of the interplay between these molecular pathways revealed that keratin 10 is the coordinating molecular hub of primary keratinocyte differentiation, apoptosis and autophagy.

Abstract
Photodynamic treatment (PDT) could be a viable option to decontaminate food or food contact surfaces. Such applications require a rigorous method to assess the efficacy of different photosensitizer-light source systems. It is also essential to determine suitable treatment conditions to achieve desirable microbial inhibition for a given process. In this connection, we evaluated and compared the antimicrobial activity of two natural photosensitizers (aloe emodin, curcumin) under PDT based on the number of absorbed photons. The degree of bacterial inactivation was then correlated to the absorbed photons as well as the process parameters through kinetics study. The results showed that aloe emodin was more effective than curcumin against both S. aureus and E. coli when the number of absorbed photons was matched. Aloe emodin reduced about 2.3 log units of S. aureus and 1.1 log units of E. coli more than curcumin. E. coli was more resistant to PDT than S. aureus. Inactivation kinetics of S. aureus and E. coli as a function of the number of absorbed photons can be described by the Weibull model with D values of 1.296 × 1017 photons/cm2 and 2.446 × 1018 photons/cm2, R2 of 0.969 and 0.968, respectively. The interrelationship between the concentration of photosensitizer, radiant fluence, and degree of bacterial inactivation could be used to determine and optimize treatment conditions of PDT processes.

Abstract
BACKGROUND Due to increased bacterial multi-drug resistance (MDR), there is an antibiotic depletion to treat infectious diseases. Consequently, other promising options have emerged, such as the antimicrobial photodynamic inactivation therapy (aPDI) based on photosensitizer (PS) compounds to produce light-activated local oxidative stress (photooxidative stress). However, there are scarce studies regarding the mode of action of PS compounds to induce photooxidative stress on pathogenic γ-proteobacteria such as MDR-Klebsiella pneumoniae. METHODOLOGY The mode of action exerted by the cationic Ir(III)-based PS (PSIR-3) to inhibit the growth of K. pneumoniae was analyzed. RT-qPCR determined the transcriptional response induced by PSIR-3 on bacteria treated with aPDI. The expression levels of genes associated with a bacterial oxidative response, such as oxyR and sodA, and the extracytoplasmic, regulators rpoE and hfq were determined. Also, were determined the transcriptional response of the extracytoplasmic factors mrkD, acrB, magA, and rmpA. RESULTS At 17 μW/cm2 photon flux and 4 μg/mL of the PSIR-3 compound, the K. pneumoniae growth was inhibited in 3 log10. Compared with untreated bacteria, the transcriptional response induced by PSIR-3 occurs via the extracytoplasmic sigma factor rpoE and hfq. In contrast, no participation in the oxyR pathway or induction of the sodA gene was observed. This response was accompanied by the upregulation of the extracytoplasmic virulence factors mrkD, magA, and rmpA. CONCLUSIONS PDI aPDI produced by PSIR-3 kills K. pneumoniae and may induce damage to the bacterial envelope. The bacterium tries to avoid this injury by activation of extracytoplasmic factors mediated through the rpoE regulon.

Abstract
Recently, a new type of spin labels based on photoexcited triplet molecules was proposed for nanometer scale distance measurements by pulsed dipolar electron paramagnetic resonance (PD EPR). However, such molecules are also actively used within biological complexes as photosensitizers for photodynamic therapy (PDT) of cancer. Up to date, the idea of using the photoexcited triplets simultaneously as PDT agents and as spin labels for PD EPR has never been employed. In this work, we demonstrate that PD EPR in conjunction with other methods provides valuable information on the structure and function of PDT candidate complexes, exemplified here with porphyrins bound to human serum albumin (HSA). Two distinct porphyrins with different properties were used: amphiphilic meso-tetrakis(4-hydroxyphenyl)porphyrin (mTHPP) and water soluble cationic meso-tetrakis(N-methyl-4-pyridyl)porphyrin (TMPyP4); HSA was singly nitroxide-labeled to provide a second tag for PD EPR measurements. We found that TMPyP4 locates in a cavity at the center of the four-helix bundle of HSA subdomain IB, close to the interface with solvent, thus being readily accessible to oxygen. As a result, the photolysis of the complex leads to photooxidation of HSA by generated singlet oxygen and causes structural perturbation of the protein. Contrary, in case of mTHPP porphyrin, the binding occurs at the proton-rich pocket of HSA subdomain IIIA, where the access of oxygen to a photosensitizer is hindered. Structural data of PD EPR were supported by other EPR techniques, laser flash photolysis and protein photocleavage studies. Therefore, pulsed EPR on complexes of proteins with photoexcited triplets is a promising approach for gaining structural and functional insights into such PDT agents.

Abstract
Reactive oxygen species (ROS) may severely affect the biochemical viability of most cells. However, ROS may act also as key second messengers regulating important physiological functions in eukaryotic organisms. Of special interest is the potential role of ROS in the regulation of stem cell function and tissue homeostasis and regeneration in adult mammalian tissues. In this context, the hair follicle constitutes an excellent experimental model to study this aspect of ROS biology.Here we present a robust protocol to promote a sustained growth of ex vivo cultured human hair follicles based on the induction of a transient/modulable production of nonlethal endogenous ROS levels in the tissue through a protoporphyrin IX-dependent photodynamic procedure. The light-switchable ROS production activates hair follicle stem cell niches, induces cell proliferation, and maintains the growth/anagen phase for long time. This approach constitutes a complementary experimental tool to study the physiological roles of ROS in human tissues.

Abstract
Photobiological properties of phthalocyanine photosensitizers, namely, clinically approved Photosens and new compounds Holosens and Phthalosens were analyzed on transitional cell carcinoma of the urinary bladder (T24) and human hepatic adenocarcinoma (SK-HEP-1). Photosens is a sulfated aluminum phthalocyanine with the number of sulfo groups 3.4, which is characterized by a high degree of hydrophilicity, slow cellular uptake, localization in lysosomes and the lowest photodynamic activity. Holosens is an octacholine zinc phthalocyanine, a cationic compound with significant charge. Holosens more efficiently enters the cells; it is localized in Golgi apparatus in addition to lysosomes and exhibits a significant inhibitory effect on cell viability upon irradiation. The highest photodynamic activity was demostrated by Phthalosens. Phthalosens is a metal-free analog of Photosens with a number of sulfo groups 2.5, which determines its amphiphilicity. Phthalosens is characterized by the highest rate of cellular uptake through the outer cell membrane, localization in cell membrane as well as in lysosomes and Golgi apparatus, and the highest activity upon irradiation among the photosensitizers studied. In general, changes in the physicochemical properties of Holosens and Phthalosens ensured an increase in their efficiency in vitro compared to Photosens. The features of accumulation, intracellular distribution and their interrelation with photodynamic activity, revealed in this work, indicate the prospects of Phthalosens and Holosens for clinical practice.

Abstract
For the purpose of precision theranostic of tumor, multifunctional drug delivery systems are always receiving great attentions. Here, we developed a zinc phthalocyanine-soybean phospholipid (ZnPc-SPC) complex based drug delivery system with doxorubicin (Dox) as loading cargo to achieve additional chemotherapy while the carrier itself could serve as multifunctional and switchable theranostic agent. In the early phase, the ZnPc-SPC complex assembled to nanostructure displaying photothermal therapy (PTT) and photoacoustic (PA) properties while in the late phase, the prepared NPs dis-assembled into ZnPc-SPC complex again performing photodynamic therapy (PDT) and low-background fluorescence (FL) image. With the decoration of folate receptors α (FRα) targeted MTX, Dox-loaded, MTX-decorated self-assembled ZnPc-SPC complex NPs (DZSM) was formed. In vitro and in vivo evaluations both indicated that DZSM presented high selectivity for FRα over-expressed tumor cells, excellent switchable PA/FL image, significant multiphase PTT/PDT effect, as well as great synergetic therapy potential, leading to notable inhibition of tumor growth.

Abstract
An interest to H2O2 accumulation under photodynamic treatment can be explained by its participation in intracellular signal cascades. It is important not only to detect H2O2 generation, but also to trace the dynamics of its intracellular content. In the present study the dynamics of cellular H2O2 content under photodynamic treatment was analyzed using genetically encoded reversible H2O2-sensitive sensor HyPer. Real-time detecting of H2O2 production after photodynamic treatment was performed using the protein sensor and individual features of action of different photosensitizers were revealed. Photodynamic treatment with a number of chlorin and phthalocyanine photosensitizers was found to induce secondary production of H2O2 in the cells. Three types of dynamic responses were registered: monotonous increase of H2O2 level during the entire observation time in the presence of Fotoditazin and Holosens; transient short-term accumulation in the presence of Radachlorin and Phthalosens; and relatively low-level stable increase in the presence of Photosens. The listed photosensitizers differ significantly in intracellular localization and physicochemical properties, which can determine the differences in the response of H2O2 after the photodynamic treatment. In general, it has been shown that the rapid transient H2O2 response is typical for hydrophobic compounds localized in membrane cell structures, whereas in the presence of more hydrophilic dyes a prolonged monotonous H2O2 accumulation occurs.

Abstract
Metalloporphyrins are an important group of sensitizers with a porphyrin skeleton. Their photophysical properties are significantly affected by the nature of the central ion. In this work, we focus on the mechanical properties of a cervix carcinoma cell line which underwent photodynamic treatment (PDT) with MgTPPS4 photosensitzer. Atomic force microscopy alongside confocal microscopy was used to quantify and qualify the structural characteristics before and after PDT. Cells before PDT showed a fine actin network and higher elasticity with the median of Young modulus 12.2 kPa. After PDT, the median of Young modulus was 13.4 kPa and a large redistribution in the actin network was observed.

Abstract
A rare case of juxtapapillary retinal capillary hemangioma (JRCH) with tractional macular detachment that was managed successfully with minimally invasive 25-gauge vitreoretinal surgery, followed by two sessions of half-fluence photodynamic treatment (PDT) with good visual outcome, is presented. A 13-year-old female patient had progressive deterioration of the vision of her right eye due to the presence of tractional macular detachment associated with JRCH in von Hippel-Lindau (VHL) disease. A 25-gauge sutureless vitreoretinal surgery was successfully performed. Two months following surgery, the JRCH was treated with two sessions of half-fluence PDT at an interval of 4 months. Visual acuity improved from a preoperative level of 20/50 to 20/25 24 months postoperatively. Resolution of the tractional macular detachment, reduction of papillomacular area fluid, and reduction in size of the JRCH were observed during the follow-up period. No serious adverse events were observed. Small-gauge vitreoretinal surgery followed by PDT can be effective and safe in relieving tractional macular detachment and recovering useful visual acuity in JRCH in VHL disease.

Abstract
Antimicrobial photodynamic treatment combines the use of photosensitizers (PSs) and visible light to kill bacterial cells. Cationic porphyrins are PSs largely used against bacteria and, among them, those featuring one positive charge on each of the 5,10,15,20-tetraaryl substituent (tetracationic) are the most used. The aim of this study was to synthesize two dicationic 5,15-di(N-alkyl-4-pyridyl)porphyrins, bearing methyl (PS 3) and benzyl (PS 4) N-alkylating groups, and to compare the efficiency in antibacterial photodynamic treatment, upon irradiation with a halogen-tungsten white lamp. The killing efficiency of the PS 4 was constantly found higher than that of the PS 3 against both pure and mixed cultures of laboratory model microorganisms as well as against wild wastewater microflora. The two PSs are comparable as regards singlet oxygen generation, but show a different repartition coefficient; the more lipophilic benzylated PS 4 shows a better interaction with the bacterial cells than the methylated one (PS 3). The data support the hypothesis that an efficient PS-cell binding is required to obtain significant effects. A correlation among cell binding, photoinactivation and PS lipophilicity is suggested.

Abstract
Bile-duct invasion is rare in patients with hepatocellular carcinoma (HCC). We report a case that received peroral direct cholangioscopy (PDCS)-guided endoscopic biopsy and photodynamic treatment (PDT) for recurrent HCC with intraductal tiny nodular tumor growth. A 64-year-old woman presented with recurrent right upper-quadrant pain. Six months previously she had been diagnosed with HCC with bile-duct invasion in the right anterior segment and had received right anterior segmentectomy. On pathological examination, the margin of resection was clear, but macroscopic bile-duct invasion was noted. On admission, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) revealed a 0.5-cm-sized polypoid mass at the hilar portion. ERCP-guided biopsy failed, and an ampullary stricture was noted. PDCS-guided endoscopic biopsy was thus performed, and histopathology of the retrieved specimen revealed HCC. The patient submitted to PDT. There was no procedure-related complication. After 1 month of PDT the polypoid lesion and scar change at the hilar lesion had disappeared.
