    Abstract The neurologic complications associated with the coronavirus disease 2019 (COVID-19) is becoming more prevalent in children after the appearance of the Omicron strain. An association between COVID-19 and posterior reversible encephalopathy (PRES) has been consistently reported in adults, but little information is available in the pediatric age group. There are only few case reports of COVID-19-related PRES in children, and all of these patients were either on some type of immunomodulatory medications or whose general condition was severe. The present case, a 9-year-old Japanese boy, who had no fever but vomited several times from days 1-4 of a COVID-19 infection had an afebrile seizure on the 8th day of his illness. The patient had no history of hypertension, and had not previously been administered any immunosuppressive drugs before or during the period of his COVID-19 infection. On admission, his physical findings were unremarkable, except for a high blood pressure. The results obtained by brain computed tomography and magnetic resonance imaging were consistent with PRES. The patient recovered with no sequelae after treatment with antihypertensive drugs. Further investigations did not suggest any underlying disease that could have caused the transient hypertension. Although PRES is relatively rare in children, pediatricians should keep in mind that this syndrome can be complicated, even in children with mild COVID-19 infections.

    Abstract Influenza infection models in mice are widely used to study flu-mediated immune responses and pathology. However, most laboratory mice are housed at 20 °C and 50% relative humidity (RH). To better recapitulate influenza epidemics and immune responses during winter seasons, mice were housed at 20 °C under different humidity conditions, 10-20% or 50% RH. Here, we describe a protocol for using aerosolized droplets to infect mice with influenza under different environmental conditions. Using this method enables influenza infection studies performed under more physiologically relevant conditions which better mimics human viral exposure.

    Abstract HIV-1 persists during antiretroviral therapy (ART) due to long-lived and proliferating latently-infected host cells, with the outcome being an incomplete cure. The latently-infected cells, or reservoir cells, are transcriptionally absent and invisible to the immune response. Elimination of latency is one strategy in activating virus production, making it visible to immune clearance. We previously showed that Ephedrae herba reactivated HIV-1 from latency. In this study, we used ephedrine, a major component of Ephedra herba, to reactivate HIV-1 from latency. The results showed that ephedrine enhances HIV-1 reactivation in the presence of TNFα. Combination treatment demonstrates a synergistic effect of HIV-1 reactivation compared to TNFα alone. Ephedrine treatment shows a higher TNFRII expression level, which is related to increased HIV-1 reactivation. However, the mechanism of ephedrine in HIV-1 reactivation is still unclear, and may be related to TNFRII receptor expression. Our results indicate that ephedrine enhances HIV-1 reactivation from latency in combination with TNFα treatment. This new reagent could be a promising latency reversal agent (LRA).

    Abstract Crystallization by pH adjustment, as a type of reaction crystallization, is a solid-liquid separation method widely used in the area of pharmaceutical and pharmaceutical intermediate manufacturing. On the other hand, 3-alkenyl cephem compound is a typical zwitterionic pharmaceutical intermediate that possesses both an amino group and a carboxylic acid group. Such structure affords three main pH regions in solution and results in difficulties using crystallization by pH adjustment for isolation. As a consequence, 3-alkenyl cephem compound is usually crystallized at the point away from the solubility curve, causing unrestricted nucleation and flocculation behavior for the deposited particles which is difficult to filtrate. In this study, the pK
