Promotion of Bone Defect Repair Using Decellularized Antler Cancellous Bone Loaded with Deer Osteoglycin.

The combination of scaffold materials and bioactive factors is a promising strategy for promoting bone defect repair in tissue engineering. Previous studies have shown that osteoglycin (OGN) is highly expressed in the bone repair process using deer antler as an animal model of bone defects. It suggests that OGN may be a key active component involved in the bone repair process.

Mycobacterium tuberculosis Rv3435c gene regulates inflammatory cytokines and is involved in lung injury and mycobacterial survival in mice.

Mycobacterium tuberculosis enters the body through the respiratory tract, produces and releases virulence proteins through a variety of mechanisms, regulates the host immune mechanism through a variety of ways, and then survives in the body for a long time. These depend on virulence genes encoded by Mycobacterium tuberculosis. Previous studies found that the Rv3435c gene of Mycobacterium tuberculosis is highly conserved in pathogenic mycobacterium, but not conserved in non-pathogenic mycobacterium, which may be a potential virulence gene, and inhibit the secretion of inflammatory factors in RAW264.

Mycobacterium tuberculosis Rv1048c affects the biological characteristics of recombinant Mycobacterium smegmatis.

Tuberculosis is a serious, infectious, zoonotic disease caused by Mycobacterium tuberculosis. Infections are transmitted in humans and livestock via aerosols. Rv1048c is a hypothetical unknown protein in the standard strain of Mycobacterium tuberculosis H37Rv.

Decellularized Antler Cancellous Bone Matrix Material Can Serve as Potential Bone Tissue Scaffold.

Due to the limited supply of autologous bone grafts, there is a need to develop more bone matrix materials to repair bone defects. Xenograft bone is expected to be used for clinical treatment due to its exact structural similarity to natural bone and its high biocompatibility. In this study, decellularized antler cancellous bone matrix (DACB) was first prepared, and then the extent of decellularization of DACB was verified by histological staining, which demonstrated that it retained the extracellular matrix (ECM).

Establishment of a real-time fluorescent quantitative PCR detection method and phylogenetic analysis of BoAHV-1.

Background: Infectious bovine rhinotracheitis (IBR), caused by Bovine alphaherpesvirus-1 (BoAHV-1), is an acute, highly contagious disease primarily characterized by respiratory tract lesions in infected cattle. Due to its severe pathological damage and extensive transmission, it results in significant economic losses in the cattle industry. Accurate detection of BoAHV-1 is of paramount importance.

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).

ARHGEF18 can promote BVDV NS5B activation of the host NF-κB signaling pathway by combining with the NS5B-palm domain.

Rho guanine nucleotide exchange factor 18 (ARHGEF18) is a member of the Rho guanine nucleotide exchange factor (RhoGEF) family. RhoGEF plays an important role in the occurrence of tumors and neurological diseases; however, its involvement in host cell resistance against pathogenic microorganisms is mostly unknown. Herein, we report that bovine viral diarrhea virus (BVDV) nonstructural protein 5B (NS5B) can activate the nuclear factor kappa B (NF-κB) signaling pathway to induce an immune response.

Prevalence and risk factors of spp. in milk samples from dairy cows with mastitis-A global systematic review.

Introduction: The overall prevalence of spp., a group of important zoonotic pathogens, in the global dairy herds and the risk of cross-species transmission between humans and dairy cows remain to be clarified. This systematic review aimed to determine the prevalence of spp.

The effect of fibroblast growth factor 21 on a mouse model of bovine viral diarrhea.

Previously, we researched that bovine viral diarrhea virus (BVDV) induced a very significant increase in fibroblast growth factor 21 (FGF21) expression in mouse liver and that FGF21 was increased in the peripheral blood of BVD cattle and BVD mice. To determine the role of FGF21 in relieving clinical symptoms and inhibiting the intestinal damage caused by BVDV in BVD development in mice, BALB/c mice were intraperitoneally injected with cytopathic biotype (cp) BVDV-LS01 (isolated and identified by our group) to establish a BVD mouse model. The role of FGF21 in the BVD mouse model was investigated by injecting the mice with FGF21.

The combination of SMRT sequencing and Illumina sequencing highlights organ-specific and age-specific expression patterns of miRNAs in Sika Deer.

Due to the lack of high-quality Sika Deer () transcriptome and sRNAome across multiple organs or development stages, it is impossible to comprehensively analyze the mRNA and miRNA regulatory networks related to growth, development and immunity response. In this study, we used single molecule-real time sequencing (SMRT-seq) and Illumina sequencing methods to generate transcriptome and sRNAome from ten tissues and four age groups of Sika Deer to help us understand molecular characteristics and global miRNA expression profiles. The results showed that a total of 240,846 consensus transcripts were generated with an average length of 2,784 bp.

Phage resistance mutation triggered by OmpC deficiency in Klebsiella pneumoniae induced limited fitness costs.

Outer membrane proteins (OMPs) play an important role in bacterial fitness costs. Derived from the interaction between Klebsiella pneumoniae K7 and phage GH-K3, K7R is an outer membrane porin-deficient phage-resistant mutant strain triggered by ompC deletion, exhibits expression inhibition of OmpC, OmpN, KPN_02430 and OmpF, but its fitness costs and regulatory mechanism remains unknown. In this study, compared with K7, K7R showed almost unaffected growth rate, slightly decreased virulence, and increased resistance to some antibiotics.

Comparison of miRNA and mRNA Expression in Sika Deer Testes With Age.

To elucidate the complex physiological process of testis development and spermatogenesis in Sika deer, this study evaluated the changes of miRNA and mRNA profiles in the four developmental stages of testis in the juvenile (1-year-old), adolescence (3-year-old), adult (5-year-old), and aged (10-year-old) stages. The results showed that a total of 198 mature, 66 novel miRNAs, and 23,558 differentially expressed (DE) unigenes were obtained; 14,918 (8,413 up and 6,505 down), 4,988 (2,453 up and 2,535 down), and 5,681 (2,929 up and 2,752 down) DE unigenes, as well as 88 (43 up and 45 down), 102 (44 up and 58 down), and 54 (18 up and 36 down) DE miRNAs were identified in 3- vs. 1-, 5- vs.
