helmingly superior to others; however, our new technique which is bar anchoring with a threaded Steinmann pin could be another solution, since it could utilize primary anchor sites and results appear to be acceptable. Level of evidence III.OBJECTIVE To evaluate the clinical efficacy of total knee arthroplasty (TKA) in the treatment of primary osteoarthritis (OA) and osteoarthritis of Kashin-Beck disease (KBD). METHODS This study enrolled 77 KBD patients (77 knees, KBD-TKA) and 75 OA patients (75 knees, OA-TKA) who underwent TKA from September 2008 to June 2018. Clinical assessments for each patient were performed pre-operatively and last follow-up. The efficacy measures included the visual analogue scale (VAS) pain score, range of motion (ROM), Hospital for Special Surgery (HSS) score, and short form 36 Health Survey (SF-36) as well as related influencing factors between the two groups. RESULTS All patients were followed up; the follow-up time of KBD-TKA was 14-132 months, with an average of 72.68 ± 37.55 months; OA-TKA was 15-120 months, with an average of 49.2 ± 28.91 months. There was no difference in pre-operative VAS score (7.29 vs. 7.24) and SF-36 (PCS) score (4.87 vs. 5.49) between KBD-TKA and OA-TKA (P > 0.05), while compared with OA, Kactors influencing the clinical efficacy of TKA. The diagnosis of KBD was an independent risk factor for poor quality of life after TKA. Pre-operative pain was a clinically important predictor of outcome.Epstein-Barr virus (EBV) is a model of herpesvirus latency and epigenetic changes. The virus preferentially infects human B-lymphocytes (and also other cell types) but does not turn them straight into virus factories. Instead, it establishes a strictly latent infection in them and concomitantly induces the activation and proliferation of infected B cells. How the virus establishes latency in its target cells is only partially understood, but its latent state has been studied intensively by many. During latency, several copies of the viral genome are maintained as minichromosomes in the nucleus. In latently infected cells, most viral genes are epigenetically repressed by cellular chromatin constituents and DNA methylation, but certain EBV genes are spared and remain expressed to support the latent state of the virus in its host cell. Latency is not a dead end, but the virus can escape from this state and reactivate. Reactivation is a coordinated process that requires the removal of repressive chromatin components and a gain in accessibility for viral and cellular factors and machines to support the entire transcriptional program of EBV's ensuing lytic phase. We have a detailed picture of the initiating events of EBV's lytic phase, which are orchestrated by a single viral protein - BZLF1. Its induced expression can lead to the expression of all lytic viral proteins, but initially it fosters the non-licensed amplification of viral DNA that is incorporated into preformed capsids. In the virions, the viral DNA is free of histones and lacks methylated cytosine residues which are lost during lytic DNA amplification. This review provides an overview of EBV's dynamic epigenetic changes, which are an integral part of its ingenious lifestyle in human host cells.People with severe psychiatric illnesses and an additional oncological illness represent great challenges to therapists in the palliative setting. Behavior patterns often appear incomprehensible or disconcerting. Depressive withdrawal or delusion in the context of a chronic psychosis can be frightening. This article outlines the epidemiological data as well as the particularities in the experience of this group of people. Following selected case studies from a psychological perspective, thoughts on the tasks of the psychiatrist in the palliative setting are presented.Pharmacotherapy is a central component in the context of an overall therapeutic concept in the treatment of adults with attention deficit hyperactivity disorder (ADHD). In this concept psychosocial interventions with psychoeducation or specific psychotherapy measures also play an important role. In adults three compounds are currently approved for the pharmacological treatment of ADHD in Germany. The long-acting stimulants retarded methylphenidate preparations and lisdexamfetamine can be prescribed. Alternatively, the adrenergic uptake inhibitor atomoxetine can be used. In several meta-analyses good effectiveness and tolerance of these drugs on ADHD psychopathology has been shown. They also improve ADHD-related disorders of emotional regulation capability and disorganization in everyday life. Importantly, an improvement in everyday functionality and quality of life under medication could also be shown in several studies. GSK3326595 cost In this review the evidence for pharmacotherapy of ADHD and its implementation into treatment of adult patients is presented.RNA polymerases (RNAPs) carry out transcription in the three domains of life, Bacteria, Archaea, and Eukarya. Transcription initiation is highly regulated by a variety of transcription factors, whose number and subunit complexity increase during evolution. This process is regulated in Bacteria by the σ factor, while the three eukaryotic RNAPs require a complex set of transcription factors (TFs) and a TATA-binding protein (TBP). The archaeal transcription system appears to be an ancestral version of the eukaryotic RNAPII, requiring transcription factor B (TFB), TBP, and transcription factor E (TFE). The function of the bacterial sigma (σ) factor has been correlated to the roles played by the eukaryotic RNAP II and the archaeal RNAP. In addition, σ factors, TFB, and TFIIB all contain multiple DNA binding helix-turn-helix (HTH) structural motifs; although TFIIB and TFB display two HTH domains, while the bacterial σ factor spans 4 HTH motifs. The sequence similarities and structure alignments of the bacterial σ factor, eukaryotic TFIIB, and archaeal TFB evidence that these three proteins are homologs.Key Points• Transcription initiation is highly regulated by TFs.• Transcription is finely regulated in all domains of life by different sets of TFs.• Specific TFs in Bacteria, Eukarya and Archaea are homologs.Separation and enrichment of phenolics from peony flowers were performed to improve the anti-biofilm and antibacterial activities for the first time. Through several times of separation, the purity of phenolics components increased significantly, and the anti-biofilm and antibacterial activities of phenolics components against E. coli and S. aureus were also significantly improved. Finally, the phenolics of peony flowers in the eluent of silica gel column chromatography (PPF-ESGCC) were found to exhibit the highest anti-biofilm and antibacterial activities. The inhibition rates of PPF-ESGCC on biofilms of E. coli and S. aureus were 77.93%, and 87.03% respectively, at a very low concentration (1/2 MIC, 0.235 mg/mL). It was found that the biofilm inhibition was achieved by inhibiting their swimming, swarming, twitching motilities, exopolysaccharide (EPS) production, and quorum sensing (QS). Moreover, there was a positive dose-dependent relationship (r = 0.75 to 1) between the inhibition rates and concentrations of PPF-ESGCC during the critical biofilm-formation stage (1-3 days). Chemical composition analysis showed the PPF-ESGCC comprised of gallic acid, kaempferol-7-O-glucoside, and apigenin-7-O-glucoside. In conclusion, PPF-ESGCC exhibited strong inhibitory effect on biofilm formation and gallic acid, kaempferol-7-O-glucoside, and apigenin-7-O-glucoside might play a crucial role in inhibiting biofilm formation. Meanwhile, this study indicated that PPF-ESGCC, a new natural QS inhibitor and biofilm inhibitor, could be used as a novel intervention strategy to enhance the safety and quality of food.Protein turnover through de novo synthesis is critical for sustainable cellular functions. We previously found that glucose consumption rate in Corynebacterium glutamicum under anaerobic conditions increased at temperature higher than the upper limit of growth temperature. Here, we showed that production of lactic and succinic acids increased at higher temperature for long-term (48 h) anaerobic reaction in metabolically engineered strains. At 42 °C, beyond the upper limit of growth temperature range, biomass-specific lactic acid production rate was 8% higher than that at 30 °C, the optimal growth temperature. In contrast, biomass-specific succinic acid production rate was highest at 36 °C, 28% higher than that at 30 °C, although the production at 42 °C was still 23% higher than that at 30 °C. As enzymes are usually unstable at high temperatures, we investigated whether protein turnover of metabolic enzymes is required for the production of lactic and succinic acids under these conditions. Interestingly, when de novo protein synthesis was inhibited by addition of chloramphenicol, after 6 h, only succinic acid production was inhibited. Because glycolytic enzymes are involved in both lactic and succinic acids synthesis, enzymes in the anaplerotic pathway and the tricarboxylic acid (TCA) cycle leading to succinic acid synthesis were likely to be responsible for its decreased production. Among the five enzymes examined, the specific activity of only pyruvate carboxylase was drastically decreased after 48 h at 42 °C. Thus, the de novo synthesis of pyruvate carboxylase is required for long-term production of succinic acid. Graphical abstract KEY POINTS • Long-term reaction for organic acids can be improved at temperature beyond ideal growth conditions. • De novo synthesis of pyruvate carboxylase is required for long-term succinic acid production.Dengue virus (DENV) is a vector-borne human pathogen that usually causes dengue fever; however, sometime it leads to deadly complications such as dengue with warning signs (DWS+) and severe dengue (SD). Several studies have shown that fusion (Fu) and bc loop of DENV envelope domain II are highly conserved and consist some of the most dominant antigenic epitopes. Therefore, in this study, Fu and bc loops were joined together to develop a short recombinant protein as an alternative of whole DENV envelope protein, and its immunogenic potential as fusion peptide was estimated. For de novo designing of the antigen, Fu and bc peptides were linked with an optimised linker so that the three dimensional conformation was maintained as it is in DENV envelope protein. The redesigned Fubc protein was expressed in E. coli and purified. Subsequently, structural integrity of the purified protein was verified by CD spectroscopy. To characterise immune responses against recombinant Fubc protein, BALB/c mice were subcutaneously injected with emulsified antigen preparation. It was observed by ELISA that Fubc fusion protein elicited higher serum IgG antibody response either in the presence or in absence of Freund's adjuvant in comparison to the immune response of Fu and bc peptides separately. Furthermore, the binding of Fubc protein with mice antisera was validated by SPR analysis. These results suggest that Fu and bc epitope-based recombinant fusion protein could be a potential candidate towards the development of the effective subunit vaccine against DENV.
