Disinfection of influenza a viruses by Hypocrellin a-mediated photodynamic inactivation.

BACKGROUND: Influenza A viruses can be transmitted indirectly by surviving on the surface of an object. Photodynamic inactivation (PDI) is a promising approach for disinfection of pathogens. METHODS: PDI was generated using Hypocrellin A (HA) and red light emitting diode (625-635 nm, 280 W/m2). Effects of the HA-mediated PDI on influenza viruses H1N1 and H3N2 were evaluated by the reduction of viral titers compared to virus control. After selection of the HA concentrations and illumination times, the applicability of PDI was assessed on surgical masks. Reactive oxygen species (ROS) were determined using a 2'-7'-dichlorodihydrofluorescein diacetate fluorescence probe. RESULTS: In solution, 10 µM HA inactivated up to 5.11 ± 0.19 log10 TCID50 of H1N1 and 4.89 ± 0.38 log10 TCID50 of H3N2 by illumination for 5 and 30 min, respectively. When surgical masks were contaminated by virus before HA addition, PDI inactivated 99.99% (4.33 ± 0.34 log reduction) of H1N1 and 99.40% (2.22 ± 0.39 log reduction) of H3N2 under the selected condition. When the masks were pretreated with HA before virus addition, PDI decontaminated 99.92% (3.11 ± 0.19 log reduction) of H1N1 and 98.71% (1.89 ± 0.20 log reduction) of H3N2 virus. The fluorescence intensity of 2',7'-dichlorofluorescein in photoactivated HA was significantly higher than the cell control (P > 0.05), indicating that HA efficiently generated ROS. CONCLUSIONS: HA-mediated PDI is effective for the disinfection of influenza viruses H1N1 and H3N2. The approach could be an alternative to decontaminating influenza A viruses on the surfaces of objects.

Carbon Nanoparticles for Thyroidectomy and Central Lymph Node Dissection for Thyroid Cancer.

PURPOSE: To evaluate whether the application of carbon nanoparticles (CNs) in total or near-total thyroidectomy combined with central lymph node dissection (CLND) for thyroid cancer (TC) is beneficial to lymph node dissection, parathyroid, and recurrent laryngeal nerve (RLN) protection. METHODS: Relevant literatures were systematically searched on PubMed, EMBASE, and Cochrane Library Databases until March 31, 2021. All analyses were performed using Revman Manager 5.3 software. The main results were the number of central lymph nodes, the number of central metastatic lymph nodes, accidental parathyroidectomy, postoperative hypoparathyroidism, postoperative hypocalcemia, and postoperative transient RLN paralysis. RESULTS: This meta-analysis identified 4 randomized controlled trials and 8 non-randomized controlled trials comprising 1870 patients. Compared with the control, the use of CNs was helpful to dissect more central lymph nodes (weighted mean difference [WMD]: 3.55, 95% confidence interval [CI]: 2.12-4.98, P < .00001) and central metastatic lymph nodes (WMD: 1.69, 95% CI:1.31-2.08, P < .00001), lower rate of accidental parathyroidectomy (odds ratio [OR]: .33, 95% CI: .23-.47, P < .00001), lower rate of both postoperative transient hypoparathyroidism (OR: .40, 95% CI: .31-.51, P < .00001), and transient hypocalcemia (OR: .37, 95% CI: .27-.51, P < .00001). However, there were no statistical difference between the groups for postoperative permanent hypoparathyroidism (OR: .29, 95% CI: .06-1.28, P = .10), postoperative permanent hypocalcemia (OR: .94, 95% CI: .10-9.16, P = .96), and postoperative transient RLN paralysis (OR: .66, 95% CI: .40-1.12, P = .12). CONCLUSIONS: The application of CNs in total or near-total thyroidectomy combined with CLND for TC can better dissect the central lymph nodes and protect parathyroid glands (PGs) and their function.

National Quality Evaluation of Medication Use for Pediatric Otitis Media With Effusion.

OBJECTIVES: Otitis media with effusion (OME) is characterized by the presence of fluid in the middle ear without the presentation of signs or symptoms of acute ear infection. The point prevalence of OME reaches as high as 60% in children younger than 2 years of age. We used the National Health Insurance Research Database (NHIRD) to investigate the use of medication in children with OME before receiving ventilation tube insertion (VTI). METHODS: Data of pediatric patients (age ≤ 12 years) who had OME and received VTI from January 1, 2011, to December 30, 2012, were retrieved from the Taiwan NHIRD. We surveyed the use of 4 medications to understand whether health care providers achieved the standards of medication use recommended by clinical practice guidelines. RESULTS: This study examines the factors affecting the use of medication for pediatric OME. Overall, according to the study's operational definitions, the use of systemic antibiotics was most common (59.9%), followed by systemic antihistamines (23.4%), systemic steroids (8.8%), and intranasal steroids (9.6%). Systemic antibiotics use was associated with 12 factors. Ten of the 12 factors increase the use of systemic antibiotics, including namely age (age > 2 years), comorbidities, teaching hospital, and community hospital. In contrast, namely catastrophic illness and watchful waiting are the 2 factors that decrease systemic antibiotics use. For the use of systemic antihistamines, systemic steroids, and intranasal steroids were related to 6, 5, and 2 factors, respectively. CONCLUSIONS: The rate of drug use differs from the rate of use recommended by commonly used clinical practice guidelines. We found that the higher the number of factors that influenced the patients' drug use, the higher the rate of drug use. According to these results, drafting a treatment guideline for OME patients in accordance with current clinical practices in Taiwan is highly recommended.

Maternal Common Cold or Fever During Pregnancy and the Risk of Orofacial Clefts in the Offspring: A Systematic Review and Meta-analysis.

The common cold and/or an associated fever during pregnancy have/has been suspected to harm the developing fetus. We sought possible correlations between a maternal common cold or fever during pregnancy and the risk of orofacial clefts in the offspring.We systematically searched PubMed and Embase using appropriate keywords, and we checked the reference lists of retrieved articles. We used random-effects models to estimate overall relative risks.Incidence of orofacial clefts.We included 13 case-control studies. Modest but statistically significant associations were found between a maternal common cold and cleft lip with or without a cleft palate (CL/CP) (odds ratio [OR] 2.17; 95% confidence interval [CI] 1.66-2.83) and a cleft palate only (CPO) (OR 3.08; 95% CI 1.5-6.34). Furthermore, maternal fever was also associated with an increased risk of CL/CP (OR 1.91, 95% CI 1.3-2.8) and CPO (OR 1.48, 95% CI 0.83-2.63) in the offspring. Further analyses of maternal influenza (alone) yielded similar results.Although evidence of heterogeneity should be carefully evaluated, our findings suggest that maternal common cold or fever during pregnancy may be associated with a greater risk of CL/CP or CPO in the offspring. Future cohort studies using valid assessments of maternal common cold exposure during pregnancy that consider the severity of fever are needed to clarify the contribution of maternal common cold or fever status to the risk of orofacial clefts in children.

Effectiveness of Mobile Medical Apps in Ensuring Medication Safety Among Patients With Chronic Diseases: Systematic Review and Meta-analysis.

BACKGROUND: Along with the rapid growth of the global aging society, the mobile and health digital market has expanded greatly. Countless mobile medical apps (mmApps) have sprung up in the internet market, aiming to help patients with chronic diseases achieve medication safety. OBJECTIVE: Based on the medication safety action plans proposed by the World Health Organization, we aimed to explore the effectiveness of mmApps in ensuring the medication safety of patients with chronic diseases, including whether mmApps can improve the willingness to report adverse drug events (ADEs), improve patients' medication adherence, and reduce medication errors. We hoped to verify our hypothesis through a systematic review and meta-analysis. METHODS: The meta-analysis was performed in strict accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included literature searched from 7 databases-PubMed, Web Of Science, Embase, CINAHL, China National Knowledge Infrastructure, Wanfang, and SinoMed. The publication time was limited to the time of database establishment to April 30, 2022. Studies were screened based on inclusion and exclusion criteria. The data extracted included authors, years of publication, countries or regions, participants' characteristics, intervention groups, and control groups, among others. Our quality assessment followed the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions, Version 6.3. RevMan 5.2 software (Cochrane Collaboration) was used to analyze the statistical data, and a sensitivity analysis was performed to assess data stability. The degree of stability was calculated by using a different statistical method and excluding large-sample studies from the analysis. RESULTS: We included 8 studies from 5 countries (China, the United States, France, Canada, and Spain) that were published from January 1, 2014, to December 31, 2021. The total number of participants was 1355, and we analyzed the characteristics of included studies, each app's features, the risk of bias, and quality. The results showed that mmApps could increase ADE reporting willingness (relative risk [RR] 2.59, 95% CI 1.26-5.30; P=.009) and significantly improve medication adherence (RR 1.17, 95% CI 1.04-1.31; P=.007), but they had little effect on reducing medication errors (RR 1.54, 95% CI 0.33-7.29; P=.58). CONCLUSIONS: We analyzed the following three merits of mmApps, with regard to facilitating the willingness to report ADEs: mmApps facilitate more communication between patients and physicians, patients attach more importance to ADE reporting, and the processing of results is transparent. The use of mmApps improved medication adherence among patients with chronic diseases by conveying medical solutions, providing educational support, tracking medications, and allowing for remote consultations. Finally, we found 3 potential reasons for why our medication error results differed from those of other studies.

MicroRNA-124 attenuates PTSD-like behaviors and reduces the level of inflammatory cytokines by downregulating the expression of TRAF6 in the hippocampus of rats following single-prolonged stress.

BACKGROUND: MicroRNA-124-3p (miR-124) plays an important role in neuroprotective functions in various neurological disorders, but whether miR-124 participates in the pathological progression of posttraumatic stress disorder (PTSD) remains poorly understood. METHODS: In the present study, we assessed the level of neuroinflammation in the hippocampus of rats exposed to single-prolonged stress (SPS) by Western blot and immunofluorescence staining, while the effect of miR-124 on PTSD-like behaviors was evaluated by behavioral test. RESULTS: Our results showed that the level of miR-124 in the hippocampus of rats exposed to SPS was downregulated and that the upregulation of miR-124 could alleviate the PTSD-like behaviors of SPS rats. This effect of miR-124 might be achieved through TNF receptor-associated Factor 6 (TRAF6), which is a target gene of miR-124 and plays an important role in the immune and inflammatory reaction by regulating nuclear factor kappa-B (NF-κB). Furthermore, we found that miR-124 not only decreased the level of proinflammatory cytokines but also increased the expression levels of synaptic proteins (PSD95 and synapsin I) and regulated the morphology of neurons. CONCLUSION: These results suggested that miR-124 might attenuate PTSD-like behaviors and decrease the level of proinflammatory cytokines by downregulating the expression of TRAF6 in the hippocampus of rats exposed to SPS.

MiR-153 downregulation alleviates PTSD-like behaviors and reduces cell apoptosis by upregulating the Sigma-1 receptor in the hippocampus of rats exposed to single-prolonged stress.

Posttraumatic stress disorder (PTSD) is a psychiatric disorder that may lead to a series of changes in the central nervous system, including impaired synaptic plasticity, neuronal dendritic spine loss, enhanced apoptosis and increased inflammation. However, the specific mechanism of PTSD has not been studied clearly. In the present study, we found that the level of miR-153-3p in the hippocampus of rats exposed tosingle-prolonged stresss (SPS) was upregulated, but its downstream target σ-1R showed a significant decrease. The downregulation of miR-153 could alleviate the PTSD-like behaviors in the rats exposed to SPS, and this effect might be related to the upregulation of σ-1R and PSD95. Furthermore, anti-miR-153 could also increase the dendritic spine density and reduce cell apoptosis in the hippocampus of SPS rats. In addition, we showed that the mTOR signaling pathway might be involved in the regulation of σ-1R in the hippocampus of rats exposed to SPS. The results of this study indicated that miR-153 might alleviate PTSD-like behaviors by regulating cell morphology and reducing cell apoptosis in the hippocampus of rats exposed to SPS by targeting σ-1R, which might be related to the mTOR signaling pathway.

miR-132 downregulation alleviates behavioral impairment of rats exposed to single prolonged stress, reduces the level of apoptosis in PFC, and upregulates the expression of MeCP2 and BDNF.

Post-traumatic stress disorder (PTSD) is usually accompanied by anxiety symptoms and decreased expression of brain-derived neurotrophic factor (BDNF), which played an important role in promoting neuronal proliferation and survival. Methyl CpG-binding protein 2 (MeCP2) is a positive mediator of BDNF and is regulated by miR-132-3p. In the present study, we explored the possible molecular mechanism of miR-132, focusing on the involvement of MeCP2 and BDNF in the formation of anxiety-like symptoms of PTSD. Single prolonged stress (SPS) was used to establish a model of PTSD in adult rats and the anxiety-like behavior was tested by the elevated plus-maze (EPM). The level of miR-132 in the prefrontal cortex (PFC) was increased and intraventricular injection of anti-miR-132 could significantly improve the anxiety-like behavior of rats exposed to SPS through MeCP2 and the subsequent upregulation of BDNF levels. Then tropomyosin-related kinase B (TrkB) and downstream signals, including MAP kinase ERK1/2 and phosphoinositol 3-kinase (PI3K)/Akt pathways, were activated by BDNF upregulation, and might participate in regulating dendritic complexity and the expression of postsynaptic density-95 (PSD95) and synapsin I in the PFC of SPS rats. Furthermore, we found that the apoptosis of cells in PFC induced by SPS procedure could be alleviated by miR-132 inhibition. Our results suggest that miR-132 might be involved in the formation of anxiety-like symptoms of adult rat PTSD models by targeting MeCP2, and this effect is related to BDNF/TrkB and its downstream ERK and Akt signaling pathways.

The novel cereblon modulator CC-885 inhibits mitophagy via selective degradation of BNIP3L.

Mitophagy is a degradative pathway that mediates the degradation of the entire mitochondria, and defects in this process are implicated in many diseases including cancer. In mammals, mitophagy is mediated by BNIP3L (also known as NIX) that is a dual regulator of mitochondrial turnover and programmed cell death pathways. Acute myeloid leukemia (AML) cells with deficiency of BNIP3L are more sensitive to mitochondria-targeting drugs. But small molecular inhibitors for BNIP3L are currently not available. Some immunomodulatory drugs (IMiDs) have been proved by FDA for hematologic malignancies, however, the underlining molecular mechanisms are still elusive, which hindered the applications of BNIP3L inhibition for AML treatment. In this study we carried out MS-based quantitative proteomics analysis to identify the potential neosubstrates of a novel thalidomide derivative CC-885 in A549 cells. In total, we quantified 5029 proteins with 36 downregulated in CRBN+/+ cell after CC-885 administration. Bioinformatic analysis showed that macromitophagy pathway was enriched in the negative pathway after CC-885 treatment. We further found that CC-885 caused both dose- and time-dependent degradation of BNIP3L in CRBN+/+, but not CRBN-/- cell. Thus, our data uncover a novel role of CC-885 in the regulation of mitophagy by targeting BNIP3L for CRL4CRBN E3 ligase-dependent ubiquitination and degradation, suggesting that CC-885 could be used as a selective BNIP3L degradator for the further investigation. Furthermore, we demonstrated that CC-885 could enhance AML cell sensitivity to the mitochondria-targeting drug rotenone, suggesting that combining CC-885 and mitochondria-targeting drugs may be a therapeutic strategy for AML patients.

SENP1-mediated deSUMOylation of USP28 regulated HIF-1α accumulation and activation during hypoxia response.

BACKGROUND: The ubiquitin-specific protease 28 (USP28) is an oncogenic deubiquitinase, which plays a critical role in tumorigenesis via antagonizing the ubiquitination and degradation of tumor suppressor protein FBXW7-mediated oncogenic substrates. USP28 controls hypoxia-dependent angiogenesis and metastasis by preventing FBXW7-dependent hypoxia-inducible transcription factor-1α (HIF-1α) degradation during hypoxia. However, it remains unclear how USP28 activation and HIF-1α signaling are coordinated in response to hypoxia. METHODS: The in vitro deubiquitinating activity assay was used to determine the regulation of USP28 by hypoxia. The co-immunoprecipitation and GST Pull-down assays were used to determine the interaction between USP28 and SENP1. The in vivo deSUMOylation assay was performed to determine the regulation of USP28 by SENP1. The luciferase reporter assay was used to determine the transcriptional activity of HIF-1α. RESULTS: Here, we report that USP28 is a SUMOylated protein in normoxia with moderate deubiquitinating activity towards HIF-1α in vitro, while hypoxia and HIF-1α activate USP28 through SENP1-mediated USP28 deSUMOylation to further accumulate HIF-1α protein in cells. In agreement with this, a SUMOylation mutant USP28 showed enhanced ability to increase HIF-1α level as well as control the transcriptional activity of HIF-1α. CONCLUSION: Collectively, our results reveal a novel SENP1-USP28-HIF-1α positive feedback loop to maximize the concentration of HIF-1a protein and amplify its downstream effects during hypoxia response.

Comparative global immune-related gene profiling of somatic cells, human pluripotent stem cells and their derivatives: implication for human lymphocyte proliferation

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity. The expression levels of global immune-related genes were determined by comparing undifferentiated and differentiated stem cells and three types of human somatic cells: dermal papilla cells, ovarian granulosa cells and foreskin fibroblast cells. We identified the differentially expressed genes CD24, GATA3, PROM1, THBS2, LY96, IFIT3, CXCR4, IL1R1, FGFR3, IDO1 and KDR, which overlapped with selected immune-related gene lists. In further analyses, mammalian target of rapamycin complex (mTOR) signaling was investigated in the differentiated stem cells following treatment with rapamycin and lentiviral transduction with specific short-hairpin RNAs. We found that the inhibition of mTOR signal pathways significantly downregulated the immunogenicity of differentiated stem cells. We also tested the immune responses induced in differentiated stem cells by mixed lymphocyte reactions. We found that CD24- and GATA3-deficient differentiated stem cells including neural lineage cells had limited abilities to activate human lymphocytes. By analyzing the transcriptome signature of immune-related genes, we observed a tendency of the hPSCs to differentiate toward an immune cell phenotype. Taken together, these data identify candidate immune-related genes that might constitute valuable targets for clinical applications.

Convergent Regulation of Candida albicans Aft2 and Czf1 in Invasive and Opaque Filamentation.

Candida albicans is the most common fungal pathogen of mucosal infections and invasive diseases in immuno-compromised humans. The abilities of yeast-hyphal growth and white-opaque switching affect C. albicans physiology and virulence. Here, we showed that C. albicans Aft2 regulator was required for embedded filamentous growth and opaque cell-type formation. Under low-temperature matrix embedded conditions, Aft2 functioned downstream of Czf1-mediated pathway and was required for invasive filamentation. Moreover, deletion of AFT2 significantly reduced opaque cell-type formation under N-acetylglucosamine (GlcNAc) inducing conditions. Ectopic expression of CZF1 slightly increased the white-opaque switching frequency in the aft2Δ/Δ mutant, but did not completely restore to wild-type levels, suggesting that Czf1 at least partially bypassed the essential requirement for Aft2 in response to opaque-inducing cues. In addition, multiple environmental cues altered AFT2 mRNA and protein levels, such as low temperature, physical environment and GlcNAc. Although the absence of Czf1 or Efg1 also increased the expression level of AFT2 gene, deletion of CZF1 remarkably reduced the stability of Aft2 protein. Furthermore, C. albicans Aft2 physically interacted with Czf1 under all tested conditions, whereas the interaction between Aft2 and Efg1 was barely detectable under embedded conditions, supporting the hypothesis that Aft2, together with Czf1, contributed to activate filamentous growth by antagonizing Efg1-mediated repression under matrix-embedded conditions.
