Abnormal Temperature Dependence of Huang-Rhys Factor and Exciton Recombination Kinetics in CsPbBr Perovskite Quantum Dots.

Anomalous thermal behaviors of excitonic luminescence in CsPbBr perovskite quantum dots (PQDs) were observed. It is found that the main luminescence peak originated from the excitonic radiative recombination assisted by the longitudinal-optical (LO) phonon, and its integrated intensity first declines as the temperature varies from 10 to 150 K and then turns to increase at ∼160 K, reaching a maximum value at 300 K. A model considering the thermal detrapping and transfer of electrons from a trap level is developed to interpret these abnormal thermal behaviors of the luminescence from the PQDs.

Identification of potential therapeutic targets for skin cutaneous melanoma on the basic of transcriptomics.

Background: Advanced skin cutaneous melanoma (SKCM) is responsible for the majority of skin cancer-related deaths. Apart from the rare BRAF V600F mutation, which can be targeted with specific drugs, there are currently no other novel effective therapeutic targets.

Methods: We used SMR analysis with cis-expressed quantitative trait locus (cis-eQTL) as the exposure variable and SKCM as the outcome variable to identify potential therapeutic targets for SKCM.

RNA-binding motif protein 24 inhibits HBV replication in vivo.

Despite the extensive use of effective vaccines and antiviral drugs, chronic hepatitis B virus (HBV) infection continues to pose a serious threat to global public health. Therapies with novel mechanisms of action against HBV are being explored for achieving a functional cure. In this study, five murine models of HBV replication were used to investigate the inhibitory effect of RNA binding motif protein 24 (RBM24) on HBV replication.

Effects of stereotactic body radiotherapy for clinical outcomes of patients with liver metastasis and hepatocellular carcinoma: A retrospective study.

This retrospective clinical study described the treatment efficacy and safety of stereotactic body radiotherapy (SBRT) for patients of hepatocellular carcinoma (HCC) and liver metastasis tumors. The therapeutic effect and prognosis of patients with liver cancer treated with stereotactic body radiation therapy (SBRT) at the Fudan University Shanghai Cancer Center (Shanghai, China) between July 2011 and December 2020 were retrospectively analyzed. Overall survival (OS), local control (LC) rates and progression-free survival (PFS) were evaluated using Kaplan-Meier analysis and the log-rank test.

Mitochondrial Glycerol-3-Phosphate Dehydrogenase Restricts HBV Replication via the TRIM28-Mediated Degradation of HBx.

Hepatitis B virus (HBV) infection affects hepatic metabolism. Serum metabolomics studies have suggested that HBV possibly hijacks the glycerol-3-phosphate (G3P) shuttle. In this study, the two glycerol-3-phosphate dehydrogenases (GPD1 and GPD2) in the G3P shuttle were analyzed for determining their role in HBV replication and the findings revealed that GPD2 and not GPD1 inhibited HBV replication.

Chemoradiotherapy with paclitaxel liposome plus cisplatin for locally advanced esophageal squamous cell carcinoma: A retrospective analysis.

Purpose: This single-center retrospective clinical study aimed to evaluate the efficacy and feasibility of chemoradiotherapy with paclitaxel liposome plus cisplatin for locally advanced esophageal squamous cell carcinoma (ESCC).

Methods: Patients with locally advanced ESCC treated with paclitaxel-liposome-based chemoradiotherapy between 2016 and 2019 were retrospectively analyzed. Overall survival (OS) and progression-free survival (PFS) were evaluated using Kaplan-Meier analysis.

Sterile 20-like kinase 3 promotes tick-borne encephalitis virus assembly by interacting with NS2A and prM and enhancing the NS2A-NS4A association.

Tick-borne encephalitis virus (TBEV) is the causative agent of a potentially fatal neurological infection in humans. Investigating virus-host interaction is important for understanding the pathogenesis of TBEV and developing effective antiviral drugs against this virus. Here, we report that mammalian ste20-like kinase 3 (MST3) is involved in the regulation of TBEV infection.

Engineering antiviral immune-like systems for autonomous virus detection and inhibition in mice.

The ongoing COVID-19 pandemic has demonstrated that viral diseases represent an enormous public health and economic threat to mankind and that individuals with compromised immune systems are at greater risk of complications and death from viral diseases. The development of broad-spectrum antivirals is an important part of pandemic preparedness. Here, we have engineer a series of designer cells which we term autonomous, intelligent, virus-inducible immune-like (ALICE) cells as sense-and-destroy antiviral system.

RBM24 inhibits the translation of SARS-CoV-2 polyproteins by targeting the 5'-untranslated region.

SARS-CoV-2 is a betacoronavirus with single-stranded positive-sense RNA, which is a serious global threat to human health. Understanding the molecular mechanism of viral replication is crucial for the development of antiviral drugs. The synthesis of viral polyproteins is a crucial step in viral progression.

DNA Repair Factor Poly(ADP-Ribose) Polymerase 1 Is a Proviral Factor in Hepatitis B Virus Covalently Closed Circular DNA Formation.

The biogenesis of covalently closed circular DNA (cccDNA) from relaxed circular DNA (rcDNA) is essential for chronic hepatitis B virus (HBV) infection. Different host DNA repair proteins are involved in the conversion of rcDNA to cccDNA. Here, we reported that the DNA repair factor poly(ADP-ribose) polymerase 1 (PARP1) is engaged in HBV cccDNA formation.

A hydrogen sulfide application can alleviate the toxic effects of cadmium on ginger (Zingiber officinale Roscoe).

Cadmium (Cd) is a poisonous element for human health. This study was conducted to explore whether HS can alleviate the toxic effects of Cd on ginger. Specifically, ginger plants were grown in soil and treated with 7.

Application of radiomics feature captured from MRI for prediction of recurrence for glioma patients.

This study aimed to develop and validate a recurrence prediction of glioma patients through a radiomics feature training and validation model. In this study, the prediction model was developed in a training cohort that consisted of 88 patients from January 2014 to July 2017 with pathologically confirmed gliomas. Their pre-radiotherapy and recurrence brain magnetic resonance imaging (MRI) images were collected, and the radiomics features were extracted.

RNA-Binding motif protein 38 (RBM38) mediates HBV pgRNA packaging into the nucleocapsid.

The binding of HBV polymerase (Pol) and the epsilon stem loop (ε) on the 5' terminal region of pgRNA is required for pgRNA packaging and HBV replication. Previous research has demonstrated that RNA binding motif protein 24 (RBM24) is involved in pgRNA packaging by mediating the interaction between HBV polymerase (Pol) and the ε element. Here, we demonstrate that RBM38 interacts with ε, pol, RBM24 and HBV core which mediate pgRNA packaging.

Repurposing of Antazoline Hydrochloride as an Inhibitor of Hepatitis B Virus DNA Secretion.

Hepatitis B virus (HBV) belongs to Hepadnaviridae family and mainly infects hepatocytes, which can cause acute or chronic hepatitis. Currently, two types of antiviral drugs are approved for chronic infection clinically: interferons and nucleos(t)ide analogues. However, the clinical cure for chronic infection is still rare, and it is a huge challenge for all researchers to develop high-efficiency, safe, non-tolerant, and low-toxicity anti-HBV drugs.

Histone deacetylase 3 promotes innate antiviral immunity through deacetylation of TBK1.

TANK-binding kinase 1 (TBK1), a core kinase of antiviral pathways, activates the production of interferons (IFNs). It has been reported that deacetylation activates TBK1; however, the precise mechanism still remains to be uncovered. We show here that during the early stage of viral infection, the acetylation of TBK1 was increased, and the acetylation of TBK1 at Lys241 enhanced the recruitment of IRF3 to TBK1.

HDAC11 restricts HBV replication through epigenetic repression of cccDNA transcription.

Hepatitis B virus (HBV) infection remains an important public health problem worldwide. Covalently closed circular DNA (cccDNA) exhibits as an individual minichromosome and is the molecular basis of HBV infection persistence and antiviral treatment failure. In the current study, we demonstrated that histone deacetylase 11 (HDAC11) inhibits HBV transcription and replication in HBV-transfected Huh7 cells.
