RESUMO
The widespread application of implantable materials has brought about a corresponding increase in implant-related complications, with implant-associated infections being the most critical. Biofilms, which often form on these implants, can significantly impede the effectiveness of traditional antibiotic therapies. Therefore, strategies such as surgical removal of infected implants and prolonged antibiotic treatment have been acknowledged as effective measures to eradicate these infections. However,the challenges of antibiotic resistance and biofilm persistence often result in recurrent or hard-to-control infections, posing severe health threats to patients. Recent studies suggest that phages, a type of virus, can directly eliminate pathogenic bacteria and degrade biofilms. Furthermore, clinical trials have demonstrated promising therapeutic results with the combined use of phages and antibiotics. Consequently, this innovative therapy holds significant potential as an effective solution for managing implant-associated infections. This paper rigorously investigates and evaluates the potential value of phage therapy in addressing orthopedic implant-associated infections, based on a comprehensive review of relevant scientific literature.
RESUMO
To understand the mutational characteristics of ATP7B gene of hepatolenticular degeneration in Xinjiang region. 24 cases were diagnosed as hepatolenticular degeneration and the exon of ATP7B gene was detected in some of their siblings and parents. A total of 45 ATP7B gene mutations (93.75%) were detected in 24 cases, of which 14 cases were homozygous mutations or compound heterozygous mutations, six cases were heterozygous mutations and four cases were no mutations. A total of 24 gene mutations and 14 SNPS were detected, including 8 new mutations: c.251C > A, c.121A > c, c.2945C > A, c.2194C > T, c.2947T > c, c.3626T > A, c.3662_3664del, c.3557G > T. The most common mutations were c.2621C > T (p.A874V) [16.7% (4/24)] and c.2333G > T (p.R778L) [12.5% (3/24)]. A total of 4 cases were diagnosed as pre-symptomatic. In this study, the most common mutation in the ATP7B gene is A874V. The most common genetic mutations in Han and Uyghur patients were different. The most common mutation in Han and Uyghur patients is R778L and A874V. Exon 11 is the gene mutations hot spot for patients with hepatolenticular degeneration in Xinjiang region, and is one of the priority exons to be detected when screening patients with suspected hepatolenticular degeneration.
RESUMO
Proteins usually associate with other molecules physically to execute their functions. Identifying these interactions is important for the functional analysis of proteins. Previously, we reported the parallel analysis of translated ORFs (PLATO) to couple ribosome display of full-length ORFs with affinity enrichment of mRNA/protein/ribosome complexes for the "bait" molecules, followed by the deep sequencing analysis of mRNA. However, the sample processing, from extraction of precipitated mRNA to generation of DNA libraries, includes numerous steps, which is tedious and may cause the loss of materials. Barcoded PLATO (PLATO-BC), an improved platform was further developed to test its application for protein interaction discovery. In this report, we tested the antisera-antigen interaction using serum samples from patients with inclusion body myositis (IBM). Tripartite motif containing 21 (TRIM21) was identified as a potentially new IBM autoantigen. We also expanded the application of PLATO-BC to identify protein interactions for JQ1, single ubiquitin peptide, and NS5 protein of Zika virus. From PLATO-BC analyses, we identified new protein interactions for these "bait" molecules. We demonstrate that Ewing sarcoma breakpoint region 1 (EWSR1) binds to JQ1 and their interactions may interrupt the EWSR1 association with acetylated histone H4. RIO kinase 3 (RIOK3), a newly identified ubiquitin-binding protein, is preferentially associated with K63-ubiquitin chain. We also find that Zika NS5 protein interacts with two previously unreported host proteins, par-3 family cell polarity regulator (PARD3) and chromosome 19 open reading frame 53 (C19orf53), whose attenuated expression benefits the replication of Zika virus. These results further demonstrate that PLATO-BC is capable of identifying novel protein interactions for various types of "bait" molecules.
RESUMO
Background: This study evaluated the relation between telomere length in lymph node [LN] and prognosis of esophageal squamous cell carcinoma [ESCC]
Materials and Methods: LNs collected from 50 patients were assessed by pathological examination and quantitative reverse transcription polymerase chain reaction [qRT-PCR], which was used for detecting telomere length. The relation between clinical factors and the number of lymph node metastasis [LNM] identified were analyzed by the x2 test. The comparison of the pattern of LNM identified by pathological examination and detection of telomere length was assessed by Wilcoxon signed-rank test. Overall survival was assessed using the Kaplan-Meier method, and Cox proportional hazard regression analysis was used to evaluate the relationship between survival and the number of LNM
Results: The best threshold values, which could define the positive metastasis by detecting the telomere length, were 1.50, using the critical value method of statistic. Length of tumor, depth of tumor invasion and differentiation of tumor correlated closely with LNM were identified by detecting telomere length. The rates of LNM identified by detecting telomere length were 34.4%, 22.4%, 22.9%, 5.0% in 108,107, 7, and 3 LN station, respectively. The number of LNM identified by detecting telomere length was more closely related to the prognosis of ESCC than that of pathological examination [HR: 1.23 VERSUS 1.04]
Conclusion: The change of telomere length in LN was closely related to the prognosis of ESCC. Delineation of clinical target volume [CTV] may benefit from the detection of telomere length in regional LN

Ionizing radiation induces the production of reactive oxygen species [ROS], which play an important causative role in cell death. The aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from Auricularia auricular [SNAAP]. Whole blood samples from healthy donors treated with SNAAP at different concentrations [20, 60, 100 microg/mL] were exposed to various doses of X-rays. Wistar rat spleen lymphocytes, in cultures, were treated with SNAAP at different concentrations [20, 60, 100 microg/mL] in the presence p.o 12 hours prior to 8 Gy gamma radiation exposure. Animals were administered with SNAAP at doses of 50, 100 or 200 mg/kg body weight d p.o 7 days prior to sub-lethal doses [6 Gy] of whole body gamma radiation exposure. SNAAP is an effective radio protector against X-ray radiation induced in vitro cellular damage in human peripheral blood. Furthermore, to support this finding the effect of SNAAP on a rat's spleen lymphocytes, when cultured and examined 24 hours after exposure to 8 Gy gamma of radiation, demonstrated the effect of polysaccharides on a rat's spleen lymphocytes, pretreated by the SNAAP, can increase the cell viability compared with irradiated group at a concentration of 20, 60 and 100 microg/mL. Likewise, this radiation-induced therapy decreased each mouse's body weight and effectively stimulated the immune system of all radiated mice. Moreover, when induced by Co60, the SNAAP decreased the level of malondialdehyde [MDA] and increased the myeloperoxidase [MPO] and the glutathione peroxidase [GSH-Px] activity in the whole blood supply of the irradiated mice. These encouraging results support further research into the clinical pharmacology of SNAAP as a novel agent for human radiation protection
