Bagged salads 'pose salmonella risk,' say researchers

Conclusion This laboratory study principally demonstrates that salad leaf juice – released from salad leaves when they are damaged or broken – supports the growth of salmonella bacteria, even at fridge temperature. If leaves are contaminated with salmonella, this isn't removed by washing in water. The results don't show that all packaged salad leaves are contaminated with gut bacteria like salmonella. What they do show is that if the bags have been contaminated with gut bacteria, these bacteria will replicate, even in the fridge, and there's little you can do to remove them. The best thing to do is to throw the bag out, although there's no way of knowing whether a particular bag is contaminated or not.   The study also cannot tell us whether we may be safer buying packaged salads unwashed, washed in spring water, or washed in chlorinated water. And neither can it tell us whether we may be safer buying non-packaged lettuce – it's still possible that an unpacked lettuce may have been contaminated at some point along the line. But any risk of food poisoning is far outweighed by the health benefits of eating fresh veg, such as reducing the risk of heart disease, stroke and some cancers. You should be reassured that the contamination levels in the food chain are in reality very low, with only 0-3% of raw food products found to be contaminated. Commonsense precautions will also reduce the risk: Hands should be thoroughly washed with soap and water,...

Background and Objectives: The benefit of tissue plasminogen activator (tPA) in acute ischemic stroke is time dependent. A 15-minute decrease in door-to-needle (DTN) time has been associated with increased odds of ambulating independently, faster discharge, and decreased odds of death. We investigated common causes of delay in DTN times in a community hospital setting in order to identify areas for improvement. Methods: A retrospective medical record review was conducted at a 574-bed community hospital. This included 100 patients who received tPA from 2016 to 2019. Time segments were classified a priori to reflect key...

Authors: Chua NK, Brown AJ Abstract Cholesterol synthesis is a fundamental process that contributes to cellular cholesterol homeostasis. Cells execute transcriptional and post-translational mechanisms to control the abundance of enzymes of the cholesterol synthesis pathway, consequently affecting cholesterol production. One such highly tuned enzyme is squalene monooxygenase (SM), which catalyzes a rate-limiting step in the pathway. A well-characterized mechanism is the cholesterol-mediated degradation of SM. Notably, lipids (cholesterol, plasmalogens, squalene, and unsaturated fatty acids) can act as cellular signa...

Contributors : Xiaowei Wang ; Fangjia Tong ; Arlise Andress ; Gongyu Tang ; Ping LiuSeries Type : Non-coding RNA profiling by high throughput sequencingOrganism : Homo sapiensExtracellular RNAs (exRNAs) have attracted great attention due to their essential role in cell-to-cell communication as well as their potential as non-invasive disease biomarkers. Recent studies have shown that exRNAs are associated with a variety of biological processes. Thus, the study of deregulated exRNAs would provide insight into disease progression. At present, there is no consensus on the best method to profile exRNA expression, which leads to...
