A non-randomised single centre cohort study, comparing standard and modified bowel preparations, in adults with cystic fibrosis requiring colonoscopy

Adults with cystic fibrosis (CF) have been reported to be at five to ten-fold risk (25 to 30 fold risk after solid organ transplant) of colorectal cancer (CRC) than the general population. Limited publications...

In addition to their antimicrobial activities, they possess other functions; e.g., cell activation, proliferation, regulation of cytokine/chemokine production, migration, diffe...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

We thank Drs Ponzetto and Figura for their interest in our study entitled “Serological response to Helicobacter pylori proteins associate with risk of colorectal cancer among diverse populations in the United States.” We appreciate their comments on a potential causal relation between H pylori VacA protein and colorectal cancer development. Their hypothesis that VacA may increase the risk of colorectal cancer through a mechanism that is similar to that identified for cystic fibrosis could be of great importance to the question of how H pylori might contribute to colorectal carcinogenesis.

Conclusion Microorganisms are involved in many life activities, and affect their surrounding environment and other organisms. Microorganisms play important roles in human heath, crop growth, livestock farming, environmental management, industrial chemical production and food production. In the 19th century, people first observed microbes using microscopes and began to study them. However, the development of high-throughput sequencing technology has led to generation of large amounts of microbial related data. As a result, machine-learning methods are now being applied to microbiological research. Here, we discuss the curr...

Blood, saliva, urine, sweat or even ear wax can carry valuable information about an individual’s medical state. Until now, even simpler tests on such bodily fluids had to be carried out at medical facilities, but with the recent uptick in the development of digital diagnostic technologies, more and more solutions appear on the market which enable the patient to do such tests at home. Here we take a look around the bodily fluid business. From bloodletting to digital sweat measurement Blood, yellow bile, black bile, phlegm. Although it doesn’t sound appealing, the ancient Greek already thought that bodily f...

Regulated mucin secretion is essential for the formation of the mucus layer that protects the underlying epithelial cells from foreign particles. Alterations in the quantity or quality of secreted mucins are therefore detrimental to airway and colon physiology. Based on various biochemical assays in several human cell lines, we report here that Na+/Ca2+ exchanger 2 (NCX2) works in conjunction with transient receptor potential cation channel subfamily M member 4 (TRPM4), and perhaps TRPM5, Na+ channels to control Ca2+-mediated secretion of both mucin 2 (MUC2) and MUC5AC from HT29-18N2 colonic cancer cells. Differentiated no...
