These residues, together with Arg8 (which is a hot-spot residue in the interaction with GS), had a restricted mobility in the presence of GS. The C-terminal region, which appeared more compact in our MD simulations of isolated IF7, seemed to be involved in non-native contacts with GS that help in the binding between the two macromolecules. In this study, high concentration of H2S (i.e., 5000 ppmv) in biogas was effectively removed by a slightly alkaline biotricking filter (BTF) with Polypropylene rings as packing material and oxygen from air as the electron acceptor. The results showed that when the inlet loading of H2S increased from 101.7 to 422.0 g/m3/h, the removal efficiency of H2S decreased from 100.0% to 91.4%, and the maximum elimination capacity (EC) was 386.0 ± 10.5 gH2S/m3/h when empty bed retention time (EBRT) was 1.0 min. The slightly alkaline condition could increase the mass transfer of H2S from gas to liquid phase and avoid the toxic effect of high concentration of H2S, resulting in high removal performance of H2S in the system. With the increase of H2S inlet loading, the ratio of SO42- in bio-desulfurization products gradually decreased, while that of S0 increased. At 101.7-210.7 gH2S/m3/h of inlet loading, SO42- was the dominant product with the ratio of above 50.00%, while S0 became the dominant product with 62.96% at 422.0 gH2S/m3/h of inlet loading. The 16S rDNA sequencing results showed that the dominant genus in the BTF was sulfide-oxidizing bacteria (SOB), with the abundance of SOB decreased with the increase of inlet loading. The dominant genus were Pseudomonas, Halothiobacillus and Sulfurimonas in the BTF at 101.7, 139.8 and 210.7 gH2S/m3/h of inlet loading, respectively. The SOB Sulfurimonas might play an important role for bio-desulfurization of high concentration of H2S in a slightly alkaline BTF under high inlet loading of H2S. BACKGROUND Helicobacter pylori (H. pylori) infection is one of the important risk factors of gastric related diseases and antibiotic therapy has become an effective treatment. At present, proton-pump inhibitor and amoxicillin-based triple therapy, including clarithromycin (PAC) and metronidazole (PAM), are two commonly used first-line therapies for H. pylori infection, which has a high incidence and possibly poor prognosis worldwide. METHODS A systematic literature review was performed using the databases PubMed, the Cochrane Library, Ovid Medline, Science Direct, Embase, Scopus and Web of Science. Only randomized clinical trials with full texts published were included. RESULTS Eighteen studies involving 3264 patients were included. The pooled risk ratios (RR) between the PAC and PAM groups were comparable in the intention-to-treat (ITT) eradication rates (71.0% versus 75.2%, RR = 0.96, p = 0.38) and per-protocol (PP) eradication rates (79.6% versus 80.1%, RR = 1.02, p = 0.65). PAM is highly effective in clarithromycin-resistant cases (70.4% versus 48.2%, RR = 0.65, p = 0.002) and that PAC showed significant efficacy in metronidazole-resistant cases (87.3% versus 58.6%, RR = 1.43, p = 0.0006). In subgroup analysis, when using low-dose PPI, the PAM group showed greater efficacy than the PAC group. Furthermore, we found that PAM showed higher effectiveness in the studies published in recent years, especially for people over 60 years old (RR = 0.80, 95% CI 0.71-0.89, p  less then  0.001). CONCLUSION In general, both PAC and PAM regimens were effective and comparable in eradicating H. pylori. However, the PAM regimen showed greater efficacy than the PAC regimen in recent years, especially for people over 60 years old. BACKGROUND Hepatitis C virus (HCV) infects more than 170 million people worldwide that represents a major threat to global public health. Several viruses including HCV have developed mechanisms against the cellular responses essentially "hijacking" the antiviral responses generated against it. Interleukin 22 activated JAK-STAT pathways are responsible for several functions including liver regeneration, antiviral responses and cell cycle regulation. OBJECTIVES Present study aims to un-reveal the speculated role of HCV core protein in perturbing IL-22 mediated JAK-STAT pathway. Principally investigating through interaction with IL-22 and SOCS-3 proteins. PATIENTS AND METHODOLOGY Total 36 liver transplant patients were enrolled in the study. Out of which 24 were found HCV + ve. Immunohistochemistry (IHC) based qualitative expression analysis of IL-22, SOCS-3 and HCV core protein was carried out. Microscopy was performed for detection and visualization of immunostained liver tissues and biopsies. RESULTS Hepatic practical to study under single study. That is why step by step unmasking the interactive role of few molecules under single study is the ideal way to resolve the impact of viral proteins on cell signaling. SOCS-3 is mediator for dysregulating IL-22 mediated liver regenerative pathway. Moreover, SOCS-3 and STAT-3 molecules are proposed to be a potential therapeutic target for managing HCC progression. Equine endometrosis is a multifactorial chronic degenerative condition, considered to be one of a major causes of equine infertility. The formation of periglandular fibrosis seems to be linked to chronic inflammation of the mare endometrium in a paracrine way and in a response to numerous forms of inflammatory stimuli elicit the net deposition of extracellular matrix (ECM) around the endometrial glands and stroma. We hypothesized some of these stimuli, such as monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6), and hyaluronan synthases (HASs), may share the nuclear factor-κB (NF-κB) dependent activation pathway. This study aimed to determine whether mRNA expression of MCP-1, IL-6, HASs, and proteins of canonical (RelA/NK-κβ1) and noncanonical (NK-κβ2) signaling pathways for NF-kB would change in subsequent categories of endometrosis during the estrous cycle. The expression of selected genes was established in mare endometrium (n = 80; Kenney and Doig categories I, IIA, IIB, III), obtained in the follicular phase (FLP) and mid-luteal phase (MLP). The high expression of RelA mRNA was observed in III, whereas of NK-κβ1 and NK-κβ2 also in IIA, and IIA and IIB, respectively. The expression of MCP-1 mRNA occurred constantly, regardless of the category, whereas IL-6 mRNA was low in IIA, IIB, and III. UNC3866 The expression of HAS 1 was high in IIA and HAS 3 in IIA, IIB, and III. All those changes were observed in FLP, but not MLP. Our results suggest that NF-κB may be involved in progression of the chronic degenerative condition of the mare endometrium, on both canonical and noncanonical pathways. The most important changes in target genes expression were observed only in FLP, which may suggest the hormone-dependent activation of the NF-κB-dependent fibrosis pathway.
