[Q]: Herpes simplex virus (HSV) infections can be treated with direct acting antivirals like acyclovir and foscarnet, but long-term use can lead to drug resistance, which motivates research into broadly-acting antivirals that can provide a greater genetic barrier to resistance. Photodynamic inactivation (PDI) employs a photosensitizer, light, and oxygen to create a local burst of reactive oxygen species that inactivate microorganisms. The botanical plant extract Orthoquin TM is a powerful photosensitizer with antimicrobial properties. Here we report that Orthoquin also has antiviral properties. Photoactivated Orthoquin inhibited herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) infection of target cells in a dose-dependent manner across a broad range of sub-cytotoxic concentrations. HSV inactivation required direct contact between Orthoquin and the inoculum, whereas pre-treatment of target cells had no effect. Orthoquin did not cause appreciable damage to viral capsids or premature release of viral genomes, as measured by qPCR for the HSV-1 genome. By contrast, immunoblotting for HSV-1 antigens in purified virion preparations suggested that higher doses of Orthoquin had a physical impact on certain HSV-1 proteins that altered protein mobility or antigen detection. Orthoquin PDI also inhibited the non-enveloped adenovirus (AdV) in a dose-dependent manner, whereas Orthoquin-mediated inhibition of the enveloped vesicular stomatitis virus (VSV) was light-independent. Together, these findings suggest that the broad antiviral effects of Orthoquin-mediated PDI may stem from damage to viral attachment proteins. facilitate attachment and entry into host cells. While HSV-1 and HSV-2 are similar, they share onlỹ 55% nucleotide identity. Lytic HSV infection of a cell begins with initial attachment to negatively charged cell surface heparan sulfate and chondroitin sulfate glycosaminoglycans, followed by stable attachment of viral glycoproteins to cell surface receptors and fusion of the viral envelope to the plasma membrane or internal membranes [2] . Fusion of viral and host membranes enables delivery of the viral nucleocapsid and tegument proteins to the cytoplasm. After the HSV nucleocapsid arrives at the nucleus and delivers the viral genome, HSV genes are expressed in an ordered temporal cascade. Viral egress requires primary envelopment of the genome-containing capsid at the inner nuclear membrane, fusion with the outer nuclear membrane and final envelopment at the trans-Golgi network. Mature virions then exit through the cellular secretory system. All stages of the HSV replication cycle offer potential targets for direct-acting antiviral (DAA) therapy. However, DAAs can be undermined by the emergence of drug resistant mutant viruses. Anti-HSV DAAs acyclovir and foscarnet offer examples of the hazards of drug resistance. These drugs interrupt HSV genome replication by different mechanisms of action. Acyclovir is a nucleoside analogue prodrug that selectively targets HSV infected cells through the action of the HSV thymidine kinase (TK) enzyme, which efficiently phosphorylates acyclovir and facilitates incorporation into nascent viral DNA genomes by the HSV DNA polymerase enzyme; incorporation of acyclovir into viral DNA terminates genome replication [3] . By contrast, the pyrophosphate analogue foscarnet blocks viral genome replication by directly inhibiting HSV DNA polymerase activity [4] . Though resistance to acyclovir occurs at a low prevalence (≤1%) in immunocompetent patients [5], immunocompromised patients experience much higher rates (4-10%) [6] . Unsurprisingly, resistance to acyclovir, and its derivatives, and to foscarnet, has been mapped to mutations in the viral thymidine kinase and the DNA polymerase catalytic subunit, respectively [7] . Currently, Abreva (n-docosanol) is the only over-the-counter topical antiviral for herpes labialis. Abreva is incorporated into the cellular plasma membrane and prevents fusion steps essential for HSV-1 entry into epithelial cells [8] . However, it must be applied repeatedly throughout the day due to rapid plasma membrane turnover and the subsequent loss of n-docosanol [9] . This host-targeted antiviral mechanism prevents development of viral resistance, but Abreva is only approved for perioral lesions, so there is a still a gap in treatment for lesions in other areas of the body. Like Abreva, there is potential for more broadly-acting antiviral drugs that exploit the physical structure of the HSV virion and block early stages of infection, such as attachment and penetration. In this study, we explored the potential of the plant-derived photosensitizing agent Orthoquin TM to mediate photodynamic inactivation (PDI) [10] of virions. The clinical utility of Orthoquin PDI of oral biofilms is an area of active investigation and there is clear potential for wider range of clinical applications. The basis of PDI is the photodynamic effect, which has been exploited in photodynamic therapy (PDT) [11, 12] for treatment of cancers [13] and age-related macular degeneration [14] . In PDT, photosensitizer compounds when exposed to visible light react with oxygen to generate reactive oxygen species (ROS) that include singlet oxygen [15] . ROS damage proteins, nucleic acids and lipids, which can lead to cell death. Some of the most well-known photosensitizing molecules for PDT are based on a tetrapyrrolic core and are found in naturally occurring pigments, such as heme, chlorophyll, and bacteriochlorophyll [16] . The accepted phototoxic mechanism for these types of photosensitizers involves the formation of an excited triplet state upon light absorption that can participate in electron (Type 1) or energy (Type 2) transfer processes. Type 1 electron transfer reactions typically lead to the formation of radical species like superoxide or hydroxyl radicals, whereas Type 2 energy transfer produces cytotoxic singlet oxygen. It is possible for a photosensitizer to initiate both Type 1 and 2 photoprocesses simultaneously, depending on the specific chemistry of the photosensitizing agent and its environment [16] . Due to the high reactivities and short lifetimes of oxidizing molecules, it is expected that only viral structures in close proximity to activated photosensitizing compounds will be affected.

[Q]: The novel coronavirus, COVID-19, has sparked an outflow of scientific research seeking to understand the virus, its spread, and best practices in prevention and treatment. If this international research effort is going to be as swift and effective as possible, it will need to rely on a principle of open science. When researchers share data, code, and software and generally make their work as transparent as possible, it allows other researchers to verify and expand upon their work. Furthermore, it allows public officials to make informed decisions. In this study, we analyzed 535 preprint articles related to COVID-19 for eight transparency criteria and recorded study location and funding information. We found that individual researchers have lined up to help during this crisis, quickly tackling important public health questions, often without funding or support from outside organizations. However, most authors could improve their data sharing and scientific reporting practices. The contrast between researchers' commitment to doing important research and their reporting practices reveals underlying weaknesses in the research community's reporting habits, but not necessarily their science.

[Q]: Objective: This study presents a preliminary report on the chest radiographic and computed tomography (CT) findings of the 2019 novel coronavirus disease (COVID-19) pneumonia in Korea. Materials and Methods: As part of a multi-institutional collaboration coordinated by the Korean Society of Thoracic Radiology, we collected nine patients with COVID-19 infections who had undergone chest radiography and CT scans. We analyzed the radiographic and CT findings of COVID-19 pneumonia at baseline. Fisher's exact test was used to compare CT findings depending on the shape of pulmonary lesions. Results: Three of the nine patients (33.3%) had parenchymal abnormalities detected by chest radiography, and most of the abnormalities were peripheral consolidations. Chest CT images showed bilateral involvement in eight of the nine patients, and a unilobar reversed halo sign in the other patient. In total, 77 pulmonary lesions were found, including patchy lesions (39%), large confluent lesions (13%), and small nodular lesions (48%). The peripheral and posterior lung fields were involved in 78% and 67% of the lesions, respectively. The lesions were typically ill-defined and were composed of mixed ground-glass opacities and consolidation or pure ground-glass opacities. Patchy to confluent lesions were primarily distributed in the lower lobes (p = 0.040) and along the pleura (p < 0.001), whereas nodular lesions were primarily distributed along the bronchovascular bundles (p = 0.006). Conclusion: COVID-19 pneumonia in Korea primarily manifested as pure to mixed ground-glass opacities with a patchy to confluent or nodular shape in the bilateral peripheral posterior lungs. A considerable proportion of patients with COVID-19 pneumonia had normal chest radiographs.
