3.6%, p  less then  0.001) and all-cause death (7.8% vs. 0%, p = 0.007). In a multivariate Cox proportional hazards regression analysis, presence of the ARC-HBR criteria [hazard ratio (HR) 4.15, 95% confidence interval (CI) 1.25-13.80, p = 0.020], body mass index (HR 1.13, 95% CI 1.01-1.27, p = 0.042), diabetes mellitus (HR 2.70, 95% CI 1.28-5.69, p = 0.009), hyperlipidemia (HR 0.41, 95% CI 0.21-0.80, p = 0.009), and infrapopliteal lesions (HR 3.51, 95% CI 1.63-7.56, p = 0.001) were independent predictors of the primary composite outcome. Approximately 70% of Japanese patients undergoing EVT met the ARC-HBR criteria, and its presence was strongly associated with adverse outcomes within 12 months of EVT.Caseous lymphadenitis (CLA) is an infectious chronic disease responsible for economic losses in sheep and goat breeding worldwide. CLA has no effective treatment, evidencing the vaccination schedule as the best control strategy. Although some commercial vaccines have been available, none of them provides total protection, which is sometimes insufficient and does not reach the same efficiency when compared in sheep and goats. They also have questionable safety levels and side effects. In light of this, several experimental vaccines are in development in order to improve safety, reproducibility, and protective immune response against the etiologic agent of CLA, Corynebacterium pseudotuberculosis. In this review, we discussed aspects as antigen, adjuvant, routes of administration, protection level, and animal models used in CLA vaccine development, as well the challenges and future perspectives. KEY POINTS Caseous lymphadenitis (CLA) does not have an appropriate commercial vaccine. Different experimental vaccines are in development aiming to protect against Corynebacterium pseudotuberculosis. An ideal vaccine for CLA is necessary for the disease control.Bioremediation of toxic metal ions using bacterial strains is a promising tool. Metal binding motifs in microbial proteins are involved in the regulation and transport of such toxic metals for metal detoxification. A bacterial strain designated TWSL_4 with metal (Cu, Cd, and Pb) resistance and removal ability was isolated and identified as a Bacillus megaterium strain using 16S rRNA gene analysis. An operon with 2 open reading frames (ORFs) was identified, cloned, and sequenced. ORF1 and ORF2 were identical to the cadmium efflux system accessory protein (CadC) and cadmium-translocating P-type ATPases (CadA) of B. megaterium strain YC4-R4 respectively. A protein homology search using Swiss model retrieved no crystal structures for CadC and CadA of Bacillus sp.. CadC of TWSL_4 had a sequence identity of 53% to the CadC (121aa) protein and 51.69% to the CadC crystal structure (1U2W.1.B; GMQE=0.75) of Staphylococcus sp. pI258. Molecular dynamic simulation studies revealed the presence of three metal binding regions in CadC of TWSL_4, [ASP7-TYR9], [ASP100-HIS102], and [LYS113-ASP116]. This is the first report showing evidence for the presence of Cd2+ and Zn2+ metal binding motifs in the CadC regulator of the Bacillus megaterium cad operon. The bacterial strain TWSL_4 was also found to contain two different P type ATPases encoding genes, cadA and zosA involved in metal resistance. Furthermore, the metal bioremediation potential of strain TWSL_4 was confirmed using an industrial effluent. KEY POINTS • Isolation of a metal-resistant bacterial strain with potential for industrial bioremediation. • Discovery of novel Cd binding sites in CadC of the cad operon from B. megaterium. • Involvement of aspartic acid in the coordination of metal ions (Cd2+).Transcription factor MESP1 is a crucial factor regulating cardiac, hematopoietic, and skeletal myogenic development. Besides, it also contributes to the generation of functional cardiomyocytes. Here, we report the soluble expression and purification of the full-length human MESP1 protein from the heterologous system, which can be delivered into the target mammalian cells. To generate this biological macromolecule, we cloned its codon-optimized gene sequence fused to a nuclear localization sequence, a cell-penetrating peptide, and a His-tag into the protein expression vector and expressed in the bacterial system (E. coli strain BL21(DE3)). AMI-1 Subsequently, we have screened and identified the optimal expression parameters to obtain this recombinant fusion protein in soluble form from E. coli and examined its expression concerning the placement of fusion tags at either terminal. Further, we have purified this recombinant fusion protein to homogeneity under native conditions. Notably, this purified fusion protein has maintained its secondary structure after purification, primarily comprising α-helices and random coils. This molecular tool can potentially replace its genetic and viral forms in the cardiac reprogramming of fibroblasts to induce a cardiac transcriptional profile in an integration-free manner and elucidating its role in various biological processes and diseases. KEY POINTS • Screening of the suitable gene construct was performed and identified. • Screening of optimal expression conditions was performed and identified. • Native purification of recombinant human MESP1 protein from E. coli was performed. • Recombinant MESP1 protein has retained its secondary structure after purification.Nitrate leaching is severe in greenhouse where excessive nitrogen is often applied to maintain high crop productivities. In this study, we investigated the effects of carbon amendment in the subsoil on nitrate leaching and the emission of greenhouse gases (CH4 and N2O) using a soil column experiment. Carbon amendment resulted in over 39% reduction in nitrate leaching and 25.3% to 60.6% increase of total N content in the subsoil zone as compared to non-amended control. Strikingly, the abundance of nirS, nosZ, and 16S rRNA were higher in the treatment than the corresponding controls while no significant effect was detected for nirK. Carbon amendment explained 14%, 10%, and 4% of the variation in the community of nosZ, nirS, and nirK, respectively. It also considerably (more than 7 times) enriched genera such as Anaerovorax, Pseudobacteroides, Magnetospirillum, Prolixibacter, Sporobacter, Ignavibacterium, Syntrophobacter, Oxobacter, Hydrogenispora, Desulfosporomusa, Mangrovibacterium, and Sporomusa, as revealed by the analysis of 16S rRNA amplicon.
