Photodisinfection of Alphaherpesvirus 1 in bovine semen. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY. B, BIOLOGY 2024; 260:113036.

Abstract
Reproductive biotechnologies are widely consolidated as a methodology in cattle breeding and have an important impact on the genetic improvement of cattle herds. Semen is an important source of dissemination of pathogenic microorganisms during reproductive procedures. To ensure the sanitary quality of the semen, it is essential to consider the presence of various microorganisms including viruses. One of the main viral agents of reproductive interest is Bovine Alphaherpesvirus 1 (BoHV-1), the etiological agent responsible for bovine rhinotracheitis and vulvovaginitis and frequently associated with reproductive efficiency of matrices and bulls. In artificial insemination centers, semen treatment is generally based only on the use of antibiotics, ignoring the possibility of inactivating other non-bacterial infectious agents. In this context, photodisinfection emerges as a promising alternative to inactivate a wide range of microorganisms, offering a complementary or substitution approach to those conventional semen treatment methods. In this work, we evaluated the use of four halogenated sulfonated porphyrins as potential photosensitizers (PSs) for photodynamic inactivation of Bovine Alphaherpesvirus I (BoHV-1) for bovine semen disinfection. The PSs were synthesized and photophysical parameters, such as UV-Vis absorption spectra and singlet oxygen quantum yield (ΦΔ) were presented. Photoinactivation of BoHV-1 was first shown in cell culture and then confirmed in artificially infected bovine semen and then the phototoxicity of PSs against spermatozoa was evaluated. All PSs were effective in BoHV-1 inactivation; however, the photosensitizer containing two chlorine atoms, showed to be more efficient due to the shorter time required for complete viral inactivation. The slight alterations in sperm kinetics were observed, but remained within those acceptable by regulatory agencies for animal reproduction. Although the methodology used in this work only included bovine semen, we emphasize that the proposed photodisinfection methodology can be adapted and applied to a wide range of biological materials and microorganisms of animal or human interest.

PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2024; 310:123902. [PMID: 38281463 DOI: 10.1016/j.saa.2024.123902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 12/08/2023] [Accepted: 01/15/2024] [Indexed: 01/30/2024]
Abstract
Hematin anhydride (β-hematin), the synthetic analogue of the malaria pigment, "hemozoin", is a heme dimer produced by reciprocal covalent bonds among carboxylic acid groups on the protoporphyrin-IX ring and the iron atom present in the two adjacent heme molecules. Hemozoin is a disposal product formed from the digestion of hemoglobin present in the red blood cells infected with hematophagous malaria parasites. Besides, as the parasites invade red blood cells, hemozoin crystals are eventually released into the bloodstream, where they accumulate over time in tissues. Severe malaria infection leads to significant dysfunction in vital organs such as the liver, spleen, and brain in part due to the autoimmune response to the excessive accumulation of hemozoin in these tissues. Also, the amount of these crystals in the vasculature correlates with disease progression. Thus, hemozoin is a unique indicator of infection used as a malaria biomarker and hence, used as a target for the development of antimalarial drugs. Hence, exploring various properties of hemozoin is extremely useful in the direction of diagnosis and cure. The present study focuses on finding one of the unknown properties of β-hematin in physiological conditions by using the Z-scan technique, which is simple, sensitive, and economical. It is observed that hemozoin possesses one of the unique material properties, i.e., nonlinearity with a detection limit of ∼ 15 µM. The self-defocusing action causes β-hematin to exhibit negative refractive nonlinearity. The observed data is analyzed with a thermal lensing model. We strongly believe that our simple and reliable approach to probing the nonlinearity of β-hematin will provide fresh opportunities for malaria diagnostics & cure in the near future.

Abstract
We report the synthesis and characterization of two novel tetra-cationic porphyrins, containing Pt(II) or Pd(II) polypyridyl complexes attached at the peripheral position of N4-macrocycle. Compounds were characterized through elemental analysis, molar conductivity, cyclic voltammetry, and spectroscopy analysis. Photophysical and photobiological parameters were also evaluated. Also, the binding capacity of each porphyrin with human serum albumin (HSA) was determined by UV-Vis, steady-state, and time-resolved fluorescence spectroscopy, combined with molecular docking calculations. The results suggest that the interaction of these compounds is spontaneous, weak to moderate, and probably occurs at site III (subdomain IB) by non-covalent forces, including van der Waals and H-bonding. Moreover, porphyrins containing peripheral complexes improve their interactions with biomolecules, show good photostability, generate reactive oxygen species under white light studied by electron paramagnetic resonance (EPR) analysis, and promote photo-damage of HSA.

Abstract
The present work reports the effects of meso-tetrakis (4-sulfonatophenyl) porphyrin (TPPS4) aggregation on its excited states absorption spectra, triplet states quenching by molecular oxygen and singlet oxygen production. Experimental techniques such as optical absorption, Z-scan with a white light continuum source and the Laser Flash Photolysis were used to fulfil the study. J-aggregates possess reverse saturable absorption in the 505-660 nm spectral range with a peak centered close to 540 nm. These facts together with their fast relaxation time suggest that they can be employed as material for ultrafast optical limiting and switching. Even though aggregation reduces the porphyrin excited-state lifetimes and quantum yields, it does not reduce the probability of the contact between the quencher and the excited aggregate. Aggregation does not change the contribution of energy transfer mechanisms to triplet state quenching by molecular oxygen. The production of singlet oxygen, the intense absorption in the phototherapeutic window and the high efficiency of conversion of light energy into heat, allow consider J-aggregates as a theranostic agent for photomedicine. It is proposed to use J-aggregates for diagnostics by photoacoustic images and in combination with a near-infrared photodynamic/photothermal dual mode therapy, thus improving synergistically the therapeutic response.

A systematic review of photodynamic therapy as an antiviral treatment: Potential guidance for dealing with SARS-CoV-2. Photodiagnosis Photodyn Ther 2021; 34:102221. [PMID: 33601001 PMCID: PMC7883714 DOI: 10.1016/j.pdpdt.2021.102221] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 02/02/2021] [Accepted: 02/08/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND SARS-CoV-2, which causes the coronavirus disease (COVID-19), presents high rates of morbidity and mortality around the world. The search to eliminate SARS-CoV-2 is ongoing and urgent. This systematic review seeks to assess whether photodynamic therapy (PDT) could be effective in SARS-CoV-2 inactivation. METHODS The focus question was: Can photodynamic therapy be used as potential guidance for dealing with SARS-CoV-2?". A literature search, according to PRISMA statements, was conducted in the electronic databases PubMed, EMBASE, SCOPUS, Web of Science, LILACS, and Google Scholar. Studies published from January 2004 to June 2020 were analyzed. In vitro and in vivo studies were included that evaluated the effect of PDT mediated by several photosensitizers on RNA and DNA enveloped and non-enveloped viruses. RESULTS From 27 selected manuscripts, 26 publications used in vitro studies, 24 were exclusively in vitro, and two had in vitro/in vivo parts. Only one analyzed publication was exclusively in vivo. Meta-analysis studies were unfeasible due to heterogeneity of the data. The risk of bias was analyzed in all studies. CONCLUSION The in vitro and in vivo studies selected in this systematic review indicated that PDT is capable of photoinactivating enveloped and non-enveloped DNA and RNA viruses, suggesting that PDT can potentially photoinactivate SARS-CoV-2.

Abstract
Artificial insemination and in vitro embryo production are increasingly used to improve the reproductive efficiency of herds, however success of these techniques depends on the sanitary quality of the semen. Insemination centers commonly use antibiotics in their routine procedure, but they are not able against viruses. In this paper, we demonstrate a new approach for disinfecting virus in bovine semen using photoimmunoinactivation, an adaptation of the photodynamic inactivation (PDI) methodology. The photosensitizers (PSs), hematoporphyrin (HP) and zinc tetracarboxy-phthalocyanine (ZnPc) were conjugated to Immunoglobulin Y (IgY) anti-bovine alphaherpesvirus 1 (BoHV-1) and used for PDI against the BoHV-1 viruses in cell culture and compared to the unconjugated PSs. Both treatments proved to be efficient, but a significant decrease in the irradiation time required to completely eliminate the virus was observed in the samples treated with the immunoconjugates. Photophysical measurements help us to understand the coupling between PSs and IgY and the evaluated production of singlet oxygen. Following the cell culture test, the same approach was applied in semen artificially infected with BoHV-1. The immunoconjugates were also efficient for complete virus inactivation up to 5 min of irradiation and proved to be safe using several parameters of sperm viability, demonstrating the feasibility of our strategy for disinfection viruses in semen.

Abstract
Photodynamic therapy (PDT) is a well-established treatment option in the treatment of certain cancerous and pre-cancerous lesions. Though best-known for its application in tumor therapy, historically the photodynamic effect was first demonstrated against bacteria at the beginning of the 20th century. Today, in light of spreading antibiotic resistance and the rise of new infections, this photodynamic inactivation (PDI) of microbes, such as bacteria, fungi, and viruses, is gaining considerable attention. This review focuses on the PDI of viruses as an alternative treatment in antiviral therapy, but also as a means of viral decontamination, covering mainly the literature of the last decade. The PDI of viruses shares the general action mechanism of photodynamic applications: the irradiation of a dye with light and the subsequent generation of reactive oxygen species (ROS) which are the effective phototoxic agents damaging virus targets by reacting with viral nucleic acids, lipids and proteins. Interestingly, a light-independent antiviral activity has also been found for some of these dyes. This review covers the compound classes employed in the PDI of viruses and their various areas of use. In the medical area, currently two fields stand out in which the PDI of viruses has found broader application: the purification of blood products and the treatment of human papilloma virus manifestations. However, the PDI of viruses has also found interest in such diverse areas as water and surface decontamination, and biosafety.

Abstract
In this work, the photodynamic efficiency of anionic meso-tetrakis sulfonophenyl (TPPS4), cationic meso-tetrakis methylpyridiniumyl (TMPyP) and their zinc complexes (ZnTPPS4 and ZnTMPyP) in the inactivation of Bovine herpesvirus type 1 (BoHV-1) was evaluated. At a non-cytotoxic concentration, all porphyrins showed significant antiviral activity after irradiation using a halogen lamp. The efficiency of the cationic porphyrins was higher than that of the anionic ones. Porphyrin complexation with zinc increases its lipophilicity and the number of absorbed photons, dramatically reducing the time for complete virus inactivation. The high superposition of the compound optical absorption and light source emission spectra played a key role in the virus inactivation efficiency. The results demonstrated the high effectivity of the photodynamic inactivation of BoHV-1. This method can be used as an auxiliary in the treatment of disorders attributed to BoHV-1 infection, and the porphyrins are promising photosensitizers for this application.

Abstract
Hepatitis B virus (HBV) is a common and widespread infection that poses a serious threat among carriers for the development of life-threatening liver diseases. The aim of the present study was to evaluate the effectiveness of the riboflavin photochemical method in inactivating duck hepatitis B virus (DHBV) in plasma via an animal model. Forty ducks were selected and randomly divided into the experimental (n=10), the virus control (n=10), the visible light control (n=10) and the plasma control group (n=10). Ducks in the experimental group were injected with plasma inactivated by the riboflavin photochemical method; in the virus control group were injected with plasma without inactivation treatment; in the visible light control group were injected with plasma irradiated by visible light; and in the plasma control group were injected with normal plasma. The serum of the ducks in each group was taken at different time points to detect DHBV-DNA levels via FQ-PCR and duck hepatitis B surface antigen (DHBsAg) via ELISA. DHBV-DNA in the experimental group was decreased gradually over time until it disappeared and there was a significant difference in DHBsAg between the experimental and control groups (P<0.05). In conclusion, the results showed that the riboflavin photochemical method is effective in the inactivation of viruses in plasma, which has relevance for preventive strategies against transfusion-derived infections.
