Antibiotic use linked to 'pre-cancerous' bowel changes

Conclusion Antibiotics, like all drugs, have side effects. We know that they affect the composition of bacteria that live in a healthy gut. This study suggests that might possibly be linked to future development of bowel cancer. However, there are some major limitations to keep in mind. Bowel polyps are very common, and they're not cancerous. Most people who have them won't know they're there, unless they have a colonoscopy. Some polyps do develop into bowel cancer, but we don't know if any of these women got bowel cancer, or how many of their polyps would have become cancerous if not treated. It's highly possible that women aged 60 might not remember accurately how often they used antibiotics in their 20s, or for how long. So we can't be sure whether women were over-estimating or under-estimating their antibiotics use. Observational studies such as this cannot show that one factor directly causes another. As the researchers say, antibiotics are used to treat bacterial infections. Infections cause inflammation, and that's a risk factor for cancer. So the study may have measured the effect of repeated exposure to bacterial infection, rather than use of antibiotics. The study was only carried out in women, so we don't know if the results apply to men. The study did a good job of controlling for other potential confounding risk factors, but no study can control for everything. It's possible there are other factors involved which we don't know about. Antibiotics have been over-us...

aredes J, Arana S Abstract Spoilage yeasts detection is the key to improve the quality of alcoholic fermentation beverages such as wine and cider. The metabolic activity of the spoilage yeast causes irreparable damage to many liters of final products every year. Therefore, winemakers and cider-house companies suffer a substantial economic impact. Thus, over the years, many detection techniques have been proposed to control the occurrence of spoilage yeast. Out of the many spoilage yeast genera, Brettanomyces is one of the most commonly encountered in the beverage industry. Leveraging its ability to thrive in wine ...

The addition of HPAM could increase the surface tension of AES solutions caused by the decrease of surfactant adsorption density at the air-water surface. The viscosity of the AES/HPAM systems were determined by the HPAM concentration. With...

Abstract An ultrasensitive label-free amperometric immunosensor for the detection of chloramphenicol (CAP) residues in milk has been developed by using a screen-printed carbon electrode laminated with a layer of poly (vinyl alcohol-co-ethylene) (PVA-co-PE) nanofibrous membrane that is covalently immobilized with a CAP antibody (anti-CAP). The performance of the PVA-co-PE nanofiber membrane (PVA-co-PE NFM) on the electrode was compared with a PVA-co-PE casted membrane (PVA-co-PE CM), necessary fabrication steps and performance of the sensors were investigated by electrochemical impedance spectroscopy (EIS). The app...

Abstract Construction of hybrid systems that combine the cancer treatment and diagnosis agents on a single platform, known as theranostic systems, have received great attentions in the field of nanobiomedicine. Here, construction and characterization of a new multifunctional hybrid theranostic system based on RGO, PDA, BSA, DTPA-Mn(II), and MTX constituents, is presented. Accordingly, GO is partially reduced and simultaneously functionalized by dopamine, leading to reduced graphene oxide/polydopamine, RGO-PDA system; and then, the bovine serum albumin protein (BSA) is grafted onto this system. The obtained system,...
