Prevalence of in deer in mainland China: a systematic review and meta-analysis.

Background: Deer tuberculosis is a chronic zoonotic infectious disease, despite the existence of socio-economic and zoonotic risk factors, but at present, there has been no systematic review of deer tuberculosis prevalence in mainland China. The aim of this meta-analysis was to estimate the overall prevalence of deer TB in mainland China and to assess possible associations between potential risk factors and the prevalence of deer tuberculosis.

Methodology: This study was searched in six databases in Chinese and English, respectively (1981 to December 2023).

Exploring novel systemic therapies for pancreatic cancer: a review of emerging anti-PD-1/PD-L1 combination therapy.

Despite attempts to apply single therapy such as surgical treatment, chemotherapy, or radiotherapy, pancreatic cancer (PC) is still one of the most lethal solid tumors. Moreover, immune checkpoint inhibitors against PD-1/PD-L1, which have shown good efficacies against many other solid tumors, have not shown encouraging results in PC treatment. Therefore, some studies are evaluating the efficacies of combination therapies based on anti-PD-1/PD-L1 for PC.

GATA-2 inhibits transforming growth factor-β signaling pathway through interaction with Smad4.

GATA-2, a member of zinc finger GATA transcription factor family, plays key role in the hematopoietic stem cells self-renewal and differentiation. The transforming growth factor-β (TGFβ) signaling pathway is a major signaling network that controls cell proliferation, differentiation and tumor suppression. Here we found that GATA-2 negatively regulated TGF-β signaling pathway in Smad4-dependent manner.

eRF1aMC and Mg(2+) dependent structure switch of GTP binding to eRF3 in Euplotes octocarinatus.

Eukaryotic translation termination is governed by eRF1 and eRF3. eRF1 recognizes the stop codons and then hydrolyzes peptidyl-tRNA. eRF3, which facilitates the termination process, belongs to the GTPase superfamily.

[Molecular characterization of Japanese encephalitis virus isolated from Gansu province in 2008].

Objective: To sequence PrM and E gene of the Japanese encephalitis virus isolated from Gansu province in 2008 and analysis the genotype of new JEV isolates and the molecular characterization of E gene.

Methods: Computer software was used to analyze nucleic acid sequence and deduced amino acid sequence, and draw phylogenetic trees, including ClustalX2.09, MegAlign and Mega4.
