Toscana virus (TOSV) is major meningitis and meningoencephalitis agent in the Mediterranean basin. Dogs are frequently exposed to TOSV; thereby they can contribute to estimating its circulation. In Algeria, little is known about its circulation, and available data are restricted to the Kabylian region. To investigate the current situation in Algeria, a total of 205 dog sera collected from 13 different wilayas over the country were analyzed by using in-house Enzyme Linked Immunosorbent Assay (ELISA) and microneutralization test (MNT). An overall seroprevalence rate of 20% (14.5-25.5%) was observed by ELISA. Whereas, a seroprevalence rate of 4.56% (1.65-7.43%) was recorded by microneutralization test elucidating the exact occurrence of TOSV exposure in dogs, in Algeria. Positive dogs were detected from the areas of Algiers, Bejaia, Blida, Bouira, Medea, Setif, and Tlemcen in the north; Laghouat in the high lands and Tamanrasset in great Sahara. Only one serum, originating from Bejaia in the north east, was positive for both testing methods, while 8/9 positive sera in MNT remained negative in ELISA. MNT negative/ELISA positive result of 40/41 might suggest evidence for dog transmission, and circulation of phleboviruses other than TOSV. Noticeably, TOSV and antigenically related viruses are largely prevalent. Thus, they are not only confined to Kabylia region, but are widespread in Algeria, despite its climate diversity.The immunomodulatory function of natural active ingredients has long been a focus of scientific research, with recent hotspots reporting targeted modulation of the follicular helper T cells (Tfh)/regulatory T cells (Treg) balance as an emerging strategy for the treatment of ulcerative colitis (UC). Here, dextran sodium sulfate induced mice UC and Astragalus polysaccharide (APS, 200 mg/kg/day) was administered simultaneously. In this study, APS effectively alleviated colitis in mice by improving survival rate, disease activity index (DAI), the change rate of body weight, colonic length and weight, and histopathological injury of the colon. Moreover, APS regulated the expression of inflammatory cytokines interleukin (IL)-2, IL-6, IL-12p70, IL-23, Tumour necrosis factor (TNF)-ɑ, and transforming growth factor (TGF)-β1 in colonic tissues of colitis mice. Importantly, APS significantly downregulated Tfh cell and the expression of its related nuclear transcription factors Blimp-1 and Bcl-6, and cytokine IL-21. Meanwhile, APS regulated the differentiation of Tfh subpopulations in colitis mice, with Tfh10 and Tfr significantly upregulated while Tfh1, Tfh17, and Tfh21 significantly downregulated. In addition, APS significantly upregulated Treg cells and the levels of its associated nuclear transcription factor Foxp3, and cytokine IL-10 in colitis mice. In conclusion, APS effectively alleviated UC by reshaping the balance of Tfh/Treg cells.Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic joint inflammation and bone erosion. The bones in the human body are constantly undergoing bone remodeling throughout their lives, which is the process of bone resorption by osteoclasts to damaged bone tissue and new bone formation by osteoblasts. Osteoblasts (OBs) are the main functional cells in bone formation, responsible for the synthesis, secretion and mineralization of the bone matrix. On the contrary, osteoclasts (OCs) mediate bone breakdown during natural bone turnover, but excessive breakdown occurs in RA. Under the condition of RA inflammation, many molecules, such as IL-1β, IL-6, TNF-α, IL-17 and hypoxia-inducible factor-1α (HIF-1α) are produced that could mediate bone loss. Studies have shown that cytokines mainly promote the formation of OCs and play a role in bone resorption by stimulating OBs to express receptor activator of NF-κB ligand (RANKL). JAK/STAT plays a crucial role in the process of bone destruction. And JAK/STAT pathway mediates the RANKL/receptor activator of NF-κB (RANK)/osteoprotegerin (OPG) axis. Tofacitinib, Baricitinib, Peficitinib and Filgotinib are now being used in patients with moderate to severe RA, as well as in patients with RA who have an inadequate response to methotrexate therapy and bone destruction. Currently, Tofacitiniband Baritinib areapprovedfor thetreatmentof moderate-to-severely active RA. JAK inhibitors have been reported to have better efficacy and lower adverse effects compared with methotrexate and adalimumab. In addition, two JAK inhibitors are currently in development the JAK1 selective Upadacitinib, and the JAK3 selective inhibitor Decernotinib. In addition to the above JAK inhibitors, some small molecular compounds inhibit bone destruction by inhibiting the Phosphorylation of STAT3. In this paper, the research progress of bone destruction participated by JAK/ STAT in rheumatoid arthritis and therapeutic effect of JAK/STAT inhibitors were reviewed.Marburgvirus (MARV), a member of the Filovirus family, causes severe hemorrhagic fever in humans. Currently, there are no approved vaccines or post exposure treatment methods available against MARV. With the aim of identifying vaccine candidates against MARV, we employ different sequence-based computational methods to predict the MHC-I and MHC-II T-cell epitopes as well as B-cell epitopes for the complete MARV genome. We analyzed the variations in the predicted epitopes among four MARV variants, the Lake Victoria, Angola, Musoke, and Ravn. We used a consensus approach to identify several epitopes, including novel epitopes, and narrowed down the selection based on different parameters such as antigenicity and IC50 values. The selected epitopes can be used in various vaccine constructs that give effective antibody responses. The MHC-I epitope-allele complexes for GP and NP with favorably low IC50 values were investigated using molecular dynamics computations to determine the molecular details of the epitope-allele complexes. This study provides information for further experimental validation of the potential epitopes and the design and development of MARV vaccines.
To explore the molecular processes associated with cellular regulatory programs in patients with COVID-19, including gene activation or repression mediated by epigenetic mechanisms. We hypothesized that a comprehensive gene expression profiling of nasopharyngeal epithelial cells might expand our understanding of the pathogenic mechanisms of severe COVID-19.

We used single-cell RNA sequencing (scRNAseq) profiling of ciliated cells (n=12,725) from healthy controls (SARS-CoV-2 negative n=13) and patients with mild/moderate (n=13) and severe (n=14) COVID-19. ScRNAseq data at the patient level were used to perform gene set and pathway enrichment analyses. We prioritized candidate miRNA-target interactions and epigenetic mechanisms.

We found that mild/moderate COVID-19 compared to healthy controls had upregulation of gene expression signatures associated with mitochondrial function, misfolded proteins, and membrane permeability. In addition, we found that compared to mild/moderate disease, severe COVID-19 had downregulation of epigenetic mechanisms, including DNA and histone H3K4 methylation and chromatin remodelling regulation. Furthermore, we found 11-ranked miRNAs that may explain miRNA-dependent regulation of histone methylation, some of which share seed sequences with SARS-CoV-2 miRNAs.

Our results may provide novel insights into the epigenetic mechanisms mediating the clinical course of SARS-CoV-2 infection.

However, there is no effective drug for preventing and treating synovitis. Some Chinese herbal formulae have been found to treat clinical OA effectively, however, their mode of action is still unclear. This study investigated the Chinese herbal formulae Zhuanggu Huoxue Tang (ZHT) underlying mechanisms for treating osteoarthritis. Transcriptome data and a network pharmacology analysis were used to investigate the biochemical pathways affected by ZHT during OA treatment with in vitro verification. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were undertaken. The interaction network of the ZHT active constituent targets was determined using Cytoscape 3.7.1 software. Molecular docking of key pathogenic proteins and components of ZHT was performed in silico to confirm the compounds' pharmaceutical activities. The results establish that JUN is a target pathway in the pathogenesis of osteoarthritis. Miltirone, one of the active ingredients of ZHT, demonstrated a suitable binding activity with JUN. Miltirone alleviates the catabolic gene expression induced by IL-1β and IL-6 in synovial fibroblasts (FLS), validating the use of Miltirone as a therapeutic drug for osteoarthritis.
The success of bone-implant prostheses depends on several factors, among them an adequate distribution and passive adaptation of occlusal loading.

this study evaluated the stress distribution in mandibular implant-supported prosthesis with internal connection morse taper interface, under effect of number of implants (4 or 5) and loadings (bilateral 100N, bilateral 300N).

the virtual models were subjected to analysis by 3D finite element method, across four experimental conditions.

The stress values were evenly distributed to the peri-implant bone and implants in all simulated conditions. Stress values did not increase in the same proportion as the increase in the applied load (from 100 to 300N). The stress value was 1.1 times higher on the implants and nearly doubled (1.5-2 times) on the peri-implant bone.

For mandibular implant-supported prosthesis, the morse taper interface is strongly recommended, with similar mechanical demand for four and five implants in both loading conditions. Five implants offered no additional benefit over four implants. The commercial pure titanium frameworks presented stress values close to the yield strength of the metal, especially at the intersection with the cantilever.

The appropriate screening inclusion criteria of low-dose computed tomography screening for lung cancer in Chinese population remains unclear and the effect of combining screening with nurse-led smoking cessation intervention is poorly understood as well.

We compared the benefits and costs of lung cancer screening with and without nurse-led smoking cessation intervention in different inclusion criteria to help select optimal screening strategies.

Different screening strategies were set based on diverse starting ages, smoking pack-year and whether nurse-led smoking cessation intervention was applied. We use nationally representative data published by the China Health and Retirement Longitudinal Survey, based on a microsimulation model, to predict incremental cost-effectiveness ratio and net health benefits under different strategies.

The incremental cost-effectiveness ratios for all lung cancer screening strategies were less than three times GDP per capita, and screening combined with smoking cessation intervention had lower incremental cost-effectiveness ratios.
