Nanomechanical detection of antibiotic-mucopeptide binding in a model for superbug drug resistance.
The alarming growth of the antibiotic-resistant superbugs methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) is driving the development of new technologies to investigate antibiotics and their modes of action. We report the label-free detection of vancomycin binding to bacterial cell wall precursor analogues (mucopeptides) on cantilever arrays, with 1...
متن کاملDrug Resistance
عفونت و تهاجم ارگانیسم های انگلی به بدن، عامل اصلی بیماری و مرگ انسانها از آغاز بشریت بوده است . در حقیقت بسیاری از اشکال حیات بدون غلبه بر ارگانیسم های زنده دیگر، قادر به ادامه زندگی نخواهند بود. انسانها معمولا مستعد تهاجم ارگانیسم های کوچکتری مانند کرمها، آمیب ها، قارچها، باکتریها و ویروسها هستند. این عوامل مکان خاصی را در بدن انتخاب کرده، مواد ضروری لازم برای حیات و تکثیر خود را دریافت نموده...
متن کاملIntrinsic Antimicrobial Resistance Determinants in the Superbug Pseudomonas aeruginosa
UNLABELLED Antimicrobial-resistant bacteria pose a serious threat in the clinic. This is particularly true for opportunistic pathogens that possess high intrinsic resistance. Though many studies have focused on understanding the acquisition of bacterial resistance upon exposure to antimicrobials, the mechanisms controlling intrinsic resistance are not well understood. In this study, we subjecte...
متن کاملWhy Local Search Excels in Expression Simplification
Simplifying expressions is important to make numerical integration of large expressions from High Energy Physics tractable. To this end, Horner’s method can be used. Finding suitable Horner schemes is assumed to be hard, due to the lack of local heuristics. Recently, MCTS was reported to be able to find near optimal schemes. However, several parameters had to be fine-tuned manually. In this wor...
متن کاملRivaroxaban Excels in ‘Real-World’ Trial
Survivors of acute lung injury are likely to experience depression and physical impairment for up to 2 years after leaving the intensive care unit. In a prospective study, 40% of patients had new-onset depression and 66% had new physical impairment after discharge. The findings seem inextricably linked on both psychological and physiological levels, Dr. Oscar J. Bienvenu and his colleagues wrot...
