What Are Common Gastrointestinal Polyposes in Children?
Discussion Bloody stools or blood in the diaper is a relatively common complaint in general pediatrics. For most patients it is often a minor concern. Commonly it is a transient problem (e.g. rectal fissure caused by constipation or trauma) or often not blood (e.g. urate crystals in the diaper, food, menses, etc.). Real blood does occur with an identifiable cause such as long distance running or heavy exercise, or milk protein allergy/sensitivity that improves with a milk-restricted diet. Many more serious causes are associated with heavier or more recalcitrant bleeding, increased defecation, abdominal pain, poor eating an...

USP25 promotes hepatocellular carcinoma progression by interacting with TRIM21 via the Wnt/ β-catenin signaling pathway
CONCLUSIONS: In summary, our data showed that USP25 was overexpressed in HCC. USP25 promoted the proliferation, migration, invasion, and EMT of HCC cells by interacting with TRIM21 to activate the β-catenin signaling pathway.PMID:37439386 | DOI:10.1097/CM9.0000000000002714

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

A Novel Human Microbe-Disease Association Prediction Method Based on the Bidirectional Weighted Network
Conclusion Human microbiome is normal flora for humans, which has been proved to be of symbiotic relationship with humans and harmless to humans. If the microbes that breed in the human body become “unhealthy,” it will definitely affect the host's physical condition. People are continuing to explore the pathologic relationship between microorganisms and the human body through high-throughput sequencing technologies and analysis systems. However, it is a pity that their pathogenesis cannot be fully understood as yet. Considering that relying only on conventional experimental methods is time-consumin...

Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Prognosis Prediction of Colorectal Cancer Using Gene Expression Profiles
Conclusion: Prognosis prediction based on informative DEGs might yield a higher predictive accuracy in CRC prognosis than the TNM staging system does. Introduction Colorectal Cancer (CRC) is one of the most common malignancies globally (1). In order to guide clinical treatment and predict prognosis, several CRC staging systems have been established, especially the American Joint committee on Cancer (AJCC) tumor-node-metastasis (TNM) system based on anatomical information, which is widely used (2). According to the TNM staging system, the survival of CRC patients is related to the size of primary tumor (T), nearby lym...

From “Serum Sickness” to “Xenosialitis”: Past, Present, and Future Significance of the Non-human Sialic Acid Neu5Gc
Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human dis...

Genome-Wide Identification of Host Genes Required for Toxicity of Bacterial Cytolethal Distending Toxin in a Yeast Model
Conclusion: The genome-wide screen in the yeast deletion library allowed us to identify a large number of host genes required for AaCdtB cytotoxicity. Further investigation could lead to more insights into the mechanisms of CdtB intoxication. Introduction Bacterial pathogens often possess several virulence factors to facilitate colonization and survival in hosts. Cytolethal distending toxin (CDT) is a genotoxin produced by many Gram-negative pathogens, such as Escherichia coli, Aggregatibacter actinomycetemcomitans, Haemophilus ducreyi, Shigella dysenteriae, Helicobacter hepaticus, and Campylobacter species (Gargi ...

Application of Antimicrobial Peptides of the Innate Immune System in Combination With Conventional Antibiotics —A Novel Way to Combat Antibiotic Resistance?
In this study erythrocytes, mononuclear cells and neutrophils, used for evaluation of cytotoxic activity of the peptides and antibiotics, were obtained from blood of healthy donors. Since authors of this article served as such the donors, ethical approval was not required by the Ethics Committee of the Institute of Experimental Medicine. All subjects/authors gave their written consent. Results Effects on Bacterial Cells Combined Antibacterial Action At the first stage of the study we explored the combined action of AMPs and lysozyme with antibiotics against drug-susceptible bacteria. MIC values for individual substance...

Quantitative Proteomic Analysis of the Response of Probiotic Putative Lactococcus lactis NCDO 2118 Strain to Different Oxygen Availability Under Temperature Variation
Conclusion In this work we applied the label-free proteomics approach to quantify the L. lactis subsp. lactis NCDO 2118 proteome in response to NAE or AN conditions under different temperatures. This comparative proteomic analysis generates different proteomic profiles which enabled the validation of in silico data of the L. lactis NCDO 2118 genome. The quantitative changes detected in our proteomic analysis showed the versatility of the functional genome of NCDO 2118, which reflects in its physiological adaptation to environmental changes that might be found during its passage inside TGI or in industrial processes. Altog...

Core Gut Bacteria Analysis of Healthy Mice
Conclusion In conclusion, our results exhibited a relatively complete picture of core gut bacteria in healthy mice that they were mainly composed of carbohydrate- and amino acids-metabolizing bacteria and immunomodulatory bacteria, as well as their ecological relationships of symbiosis or functional redundancy. It was worth noting that the core bacteria resident in healthy gut was of fundamental importance for not only the healthy physiological characteristics, but also the chronic metabolic disease phenotypes. Our study focused on the gut microbiota of healthy host, and would be an important complement to the case–...

Prostate Cancer Risk and DNA Methylation Signatures in Aging Rats following Developmental BPA Exposure: A Dose –Response Analysis
Conclusions: Developmental BPA exposures heighten prostate cancer susceptibility in a complex dose- and lobe-specific manner. Importantly, elevated carcinogenic risk is found at doses that yield undetectable serum free BPA. Dose-specific epigenetic modifications of selected genes provide a mechanistic framework that may connect early-life BPA to later-life predisposition to prostate carcinogenesis. https://doi.org/10.1289/EHP1050 Received: 1 September 2016 Revised: 13 January 2017 Accepted: 19 January 2017 Published: 11 July 2017 Address correspondence to G.S.
