Application of lentinan in suppression of Marek's disease virus infection.

Marek's disease virus (MDV) is an extremely widespread avian immunosuppressive virus. In recent years, many reports have shown that there are still cases of MDV infection and immunosuppression after immunization with the vaccine. Consequently, there is a need to develop alternative complementary approaches for strengthening the efficacy of MDV prevention and control measures.

DF-1-Derived exosomes mediate transmission of reticuloendotheliosis virus and resist REV-specific antibodies.

Background: Reticuloendotheliosis virus (REV), a member of the family Retroviridae, is a hot area of research, and a previous study showed that exosomes purified from REV-positive semen were not blocked by REV-specific neutralizing antibodies and established productive infections.

Methods: To further verify the infectivity of exosomes from REV-infected cells, we isolated and purified exosomes from REV-infected DF-1 cells and identified them using Western blot and a transmission electron microscope. We then inoculated 7-day-old embryonated eggs, 1-day-old chicks and 23-week-old hens with and without antibody treatment.

METTL5: A Potential Biomarker for Nonsmall Cell Lung Cancer That Promotes Cancer Cell Proliferation by Interacting with IGF2BP3.

To examine if METTL5 promotes the proliferation of nonsmall cell lung cancer (NSCLC) cells by interacting with IGF2BP3. The expression patterns of METTL5 and IGF2BP3 in NSCLC tissues, their relationship with survival rate, and their correlation were analyzed using bioinformatics and clinical sample analyses. The effects of METTL5 overexpression and knockdown, as well as those of knockdown and IGF2BP3 overexpression, on the proliferation of NSCLC cells were analyzed by transfecting appropriate constructs.

Immunopotentiating effect of lentinan on chicks and its inhibitory effect on Marek's disease virus infection.

Marek's disease virus (MDV) is a significant tumorigenic virus that causes severe immunosuppression in chickens. Lentinan (LNT) is an immunomodulator containing β-glucans and is widely used in areas such as antiviral, anticancer, and immune regulation. To investigate the immunomodulatory effects of LNT on specific pathogen-free (SPF) chicks and its potential to inhibit MDV infection, we conducted an MDV challenge experiment and observed the immune-enhancing effect of LNT on SPF chicks.

The causality between obstructive sleep apnea and ventricular structure and function: a bidirectional Mendelian randomization study.

Multiple observational studies have discovered a substantial link between obstructive sleep apnea (OSA) and ventricular dysfunction. However, conventional observational studies are vulnerable to causal reversal and confounding, making it challenging to infer the causes of effects and their direction. With the help of a bidirectional, two-sample Mendelian randomization (MR) study, we assessed the potential causality between OSA and left and right ventricular (LV, RV) structure and function.

HPV prevalence and genotype distribution among 38 056 women in Weifang, China: a cross-sectional study.

Therefore, investigating the HPV prevalence, age-specific, genotype distribution and the impact of the COVID-19 pandemic among large populations was essential for HPV screening and optimising vaccination.

Design: This was a cross-sectional study.

Combined inhibitory effect of interferon and antiserum on avian hepatitis E virus.

Epidemiologic investigations in recent years have shown that the detection rate of avian hepatitis E virus (HEV) in chicken flocks is increasing in China. Nevertheless, effective prevention and control measures are still lacking. In this study, specific pathogen-free (SPF) chicken serum against HEV was prepared using recombinant HEV open reading frames (ORF2 and ORF3) proteins as immunogens.

Methods: We performed a systematic literature search of PubMed, Web of Science, EMbase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, Wanfang and China Biomedical Literature Database (CBM) to identify studies evaluating the outcomes of sac embolization vs. no embolization among patients who had received EVAR.

A novel electrocoagulation process with centrifugal electrodes for wastewater treatment: Electrochemical behavior of anode and kinetics of heavy metal removal.

Anodic passivation is a key problem to impair the efficiency of in the electrocoagulation (EC) process. Process intensification of EC has attracted increasingly greater attention. In this work, a novel centrifugal electrode reactor was designed and applied in EC process to enhance the treatment of simulated heavy metal wastewater using aluminum anode.

Non-coding RNAs in cancer therapy-induced cardiotoxicity: Mechanisms, biomarkers, and treatments.

As a result of ongoing breakthroughs in cancer therapy, cancer patients' survival rates have grown considerably. However, cardiotoxicity has emerged as the most dangerous toxic side effect of cancer treatment, negatively impacting cancer patients' prognosis. In recent years, the link between non-coding RNAs (ncRNAs) and cancer therapy-induced cardiotoxicity has received much attention and investigation.

Relevance of Ferroptosis to Cardiotoxicity Caused by Anthracyclines: Mechanisms to Target Treatments.

Anthracyclines (ANTs) are a class of anticancer drugs widely used in oncology. However, the clinical application of ANTs is limited by their cardiotoxicity. The mechanisms underlying ANTs-induced cardiotoxicity (AIC) are complicated and involve oxidative stress, inflammation, topoisomerase 2β inhibition, pyroptosis, immunometabolism, autophagy, apoptosis, ferroptosis, etc.

Enhanced Antiviral Ability by a Combination of Zidovudine and Short Hairpin RNA Targeting Avian Leukosis Virus.

Avian leukosis virus (ALV) causes tumor diseases in poultry and is circulating all over the world, leading to significant economic losses. In addition, mixed infection of ALV with other viruses is very common and is often reported to contaminate live vaccines. At present, there is no effective method to suppress the replication of ALV , so it is very difficult to remove it in mixed infection.

Protective Effects of Ischemic Postconditioning on Livers in Rats with Limb Ischemia-Reperfusion via Glycogen Synthase Kinase 3 beta (GSK-3β)/Fyn/Nuclear Receptor-Erythroid-2-Related Factor (Nrf2) Pathway.

BACKGROUND Ischemia/reperfusion (I/R) injury not only exists in ischemic tissues and organs, but also can cause damage to distant tissues and organs. As the largest metabolic organ of the human body, the liver is very vulnerable to injury after limb I/R. However, the mechanism of liver injury caused by limb I/R injury has not been fully elucidated.

The fucoidan from the brown seaweed Ascophyllum nodosum ameliorates atherosclerosis in apolipoprotein E-deficient mice.

Hyperlipidemia is a major cause of atherosclerosis. Reverse cholesterol transport (RCT) is believed to attenuate hyperlipidemia and the progression of atherosclerosis. Although fucoidans are reported to have hypolipidemic effects, the underlying mechanisms are unclear.

The role of lncRNA MALAT1 in bone metastasis in patients with non-small cell lung cancer.

lncRNA metastasis-associated lung adencarcinoma transcript 1 (MALAT1) plays an important role in the metastasis of lung cancer. Yet, its role in bone metastasis and the related mechanism remain unknown. The present study aimed to investigate the role of lncRNA MALAT1 in the bone metastasis of non-small cell lung cancer (NSCLC), including the expression pattern in tumor tissues, and the effect on the apoptosis, proliferation, migration and invasion of NSCLC cells.
