This review summarizes the presentations given at the 22nd International conference on Emerging Infectious Diseases in the Pacific Rim. The purpose of this annual meeting is to foster international collaborations and address important public health issues in the Asia-Pacific region. This meeting was held in Bangkok in February 2020 and focused on emerging virus infections. Unexpectedly, the SARS-CoV-2 pandemic was in the initial stages leading to a special session on COVID-19 in addition to talks on dengue, influenza, hepatitis, AIDS, Zika, chikungunya, rabies, cervical cancer and nasopharyngeal carcinoma.Usutu virus (USUV; Flavivirus) has caused massive die-offs in birds across Europe since the 1950s. Although rare, severe neurologic disease in humans has been reported. USUV is genetically related to West Nile virus (WNV) and shares an ecological niche, suggesting it could spread from Europe to the Americas. USUV's risk of transmission within the United States is currently unknown. To this end, we exposed field-caught Aedes japonicus, Culex pipiens pipiens, and Culex restuans-competent vectors for WNV-to a recent European isolate of USUV. While infection rates for each species varied from 7%-21%, no dissemination or transmission was observed. These results differed from a 2018 report by Cook and colleagues, who found high dissemination rates and evidence of transmission potential using a different USUV strain, U.S. mosquito populations, temperature, and extrinsic incubation period. Future studies should evaluate the impact of these experimental conditions on USUV transmission by North American mosquitoes.In this study, the process of decomposition of carbon tetrachloride (CCl4) vapor in oxygen DBD at atmospheric pressure and its kinetic regularities have been studied. In the course of the experiments, it was shown that the efficiency of the decomposition of carbon tetrachloride in DBD can reach 100%. Depending on the conditions of the experiments, the effective rate constants were equal to (0.16-0.59) s-1, and the decomposition energy yields were (0.001-0.012) molecules per 100 eV of the inputed energy. The main decomposition products were CO2 and Cl2 molecules. The formation of a solid on the internal electrode of the reactor was also found. The substance contains atoms of carbon, oxygen, chlorine (COCl) = 10.380.01, as well as hydrogen atoms. The substance also contains functional groups -CH, -CH2, -OH and dimers of carboxylic (chlorocarboxylic) acids. Based on the solution of the Boltzmann equation for electrons, it is shown that for the compositions of a gas containing O2 molecules, ССl4, and decay products, the kinetic and transport characteristics of electrons are the same as in a pure oxygen discharge. Using the kinetic characteristics of electrons and the reaction rate constants the mechanisms of reactions leading to the found reaction products are proposed. It was shown that the primary reaction of destruction is the reaction of dissociation of CCl4 by electron impact, leading to the formation of CCl3• and Cl and the reaction with the O (1D) atom, as a result of which CCl3• and ClO• are formed.To assemble the genome of the marine water flea Diaphanosoma celebensis, a sentinel model for marine environmental monitoring, we constructed a high-quality genome using PromethION and HiSeq 2500 platforms. The total length of the assembled genome was 100.08 Mb, with N50 = 2.56 Mb (benchmarking universal single-copy orthologs, 96.9%) and consisted of 179 scaffolds. A total of 15,427 genes were annotated, and orthologous gene clusters in D. celebensis were analyzed and compared with those of the cladocerans Daphnia magna and Daphnia pulex. In addition, phase I, II, and III detoxification gene families of cytochrome P450s, glutathione S-transferases, and ATP-binding cassette were fully identified and revealed lineage-specific gene loss and/or expansion, suggesting that the evolution of detoxification gene families likely modulates fitness and susceptibility in response to environmental stressors. The study improves our understanding of the detoxification-related gene system and should contribute to future studies of molecular ecotoxicology in cladoceran species and their responses to emerging pollutants.
Thyroid carcinoma is the most common endocrine tumor, and thyroid papillary carcinoma is the most common form. Although thyroid papillary carcinoma presents a good prognosis, some patients still exhibit recurrence or distant metastasis. miR-1301-3p has been found involved in the occurrence and development of some special tumors. Our study aims to investigate the miR-1301-3p expression in thyroid papillary carcinoma, to explore its biological function, and to provide a potential marker for diagnosis and treatment of thyroid papillary carcinoma.

The tissue samples from 70 patients with PTC (n=35) and benign tumors (n=35) were collected respectively. miR-1301-3p expression were detected by qPCR. Diagnostic value of miR-1301-3p was analyzed by ROC curve. CCK-8 assays and flow cytometry were performed to detect the effect of miR-1301-3p on TPC-1 function. PCNA expression of protein was detected by WB.

Compared with the normal group, the expression of miR-1301-3p was obviously decreased in both benign group aigration. miR-1301-3p may serve as a potential biomarker for the early diagnosis and treatment of PTC.In this study, we assessed circulating immune cells and plasma cytokine levels in 15 pediatric patients with drug-resistant epilepsy (DRE). DRE patients had a significantly higher percentage of CD14+ monocytes positive for IL-1β, IL-1 receptor antagonist, IL-6, and TNF-α than controls. Significantly higher intracellular levels of IFN-γ in CD4+ T cells and NK cells were also found in DRE patients. The level of IL-1β+ CD14+ monocytes correlated with seizure frequency, and intracellular levels of IFN-γ in NKT-like cells were negatively correlated with the duration of epilepsy. Peripheral immune cells might be involved in the pathogenesis of DRE.Findings in humans and animals have demonstrated a potential role for Mycobacterium avium subsp. paratuberculosis (MAP) antigenic components in encephalitogenic T cell activation. Here we reported that oral administration of MAP activates the mucosal immunity and exacerbates active experimental autoimmune encephalomyelitis (EAE) in C57BL/6J mice, modulating the immune cell traffic from secondary lymphoid organs to central nervous system. The detection of antigenic mycobacterial components by intestinal antigen-presenting cells may modulate the immune system and the subsequent inflammatory status through various signaling mechanisms, including the synthesis of pro-inflammatory cytokines involved in EAE pathogenesis.
Long-term cognitive impairment is a complication of critical illness survivors. Beside its lifesaving role, mechanical ventilation has potential complications. The aim of this study is to systematically review the evidence collected in animal studies that correlate mechanical ventilation with neuroinflammation, neuronal damage and cognitive impairment.

We searched MEDLINE and EMBASE databases for studies published from inception until August 31st, 2020, that enrolled mechanically ventilated animals and reported on neuroinflammation or neuronal damage markers changes or cognitive-behavioural impairment.

Of 5583 studies, 11 met inclusion criteria. Mice, rats, pigs were used. Impact of MV 4 out of 7 studies reported higher neuroinflammation markers in MV-treated animals and 3 studies reported no differences; 7 out of 8 studies reported a higher neuronal damage and 1 reported no differences; 2 out of 2 studies reported cognitive decline up to 3days after MV. Higher Tidal volumes are associated with higher changes in brain or serum markers.

Preclinical evidence suggests that MV induces neuroinflammation, neuronal damage and cognitive impairment and these are worsened if sub-optimal MV settings are applied. Future studies, with appropriate methodology, are necessary to evaluate for serum monitoring strategies.

CRD42019148935.Upregulation of the programmed cell death receptor-1 and ligand (PD-1/PD-L1) pathway is one of many possible mechanisms of immune-evasion relevant to Epstein-Barr virus (EBV)- associated nasopharyngeal cancer (NPC). The therapeutic targeting of the PD-1/ PD-L1 axis is an area of active research in NPC and at least 8 monoclonal or bi-specific antibodies targeting this axis are currently under clinical evaluation in some of the following clinical settings (1) palliative treatment of recurrent and/or metastatic (R/M) disease; (2) radical treatment of locoregionally advanced disease in adjunct to conventional chemoradiotherapy; (3) local/ regional recurrence. PD-1 antibodies as monotherapy has been reported to yield an overall objective response in around 20-30% of patients with R/M NPC in single-armed phase II trials, and the predictive role of PD-L1 expression in NPC remains to be defined. As with other solid tumors, combinatorial strategies with cytotoxic chemotherapy, radiotherapy or other immunotherapeutic agents (such as other immune-checkpoint inhibitors, EBV-targeting cellular therapy and other immune-modulating agents) and vascular endothelial growth factor/receptor antibodies are actively being evaluated in clinical trials with single-armed or randomized designs. Selleck Bcl2 inhibitor This article will review the scientific rationale of targeting the PD1/PD-L1 axis in NPC, and summarizes the latest trials involving these agents and predictive biomarkers of response to PD-1/PD-L1 antibodies in NPC.Tumor immunotherapy has made great progress in recent years. In the tumor microenvironment, the binding of PD-1 and its ligand PD-L1 can promote tumor immune escape and tumor survival. Clinical studies have indicated that antibodies blocking PD-1 and PD-L1 have reliable effects on many advanced malignant tumors. However, no small-molecule inhibitors have been approved so far, indicating that the development of marketable small-molecules PD-1/PD-L1 targeted therapy drugs is a challenging process. Small-molecule inhibitors can overcome the limitations of monoclonal antibodies, including poor oral bioavailability, high cost, poor tissue and tumor penetration and long half-life, which prompt researchers to turn their attention to the development of peptide molecules and small-molecule inhibitors modulating PD-1/PD-L1 to overcome some disadvantages of monoclonal antibodies or targeting PD-L1 protein degradation as potential alternatives or supplements. In this review, we will focus on the peptide-based and nonpeptidic molecules against PD-1/PD-L1 base on the structural classification. More importantly, we also focus on the latest research progress of small-molecules mediated PD-L1 degradation mechanism.The loss of neurons is strongly correlated with aging and aging-associated disorders. In this study, cell viability assays and mitochondrial function were performed to evaluate the effect of new spiro-pyrazole derivatives, prepared from aldehydes and 3-amino-1-phenyl-2-pyrazolin-5-one, on neuroprotection in an in vitro model of dopaminergic cell death induced by 1-methyl-4-phenylpyridinium (MPP+). The percentages of neuroprotection by derivatives were found between 21.26% and 52.67% at selected concentrations (10-50 μM) with compound 4d exerting the best neuroprotective effect. The results show that the studied spiropyrazolones perform important roles in dopaminergic neuroprotection and can be used for potential new therapies in the treatment of neurodegenerative disorders including Parkinson's disease.
