BACKGROUND Catheter-related infections cause increased morbidity, mortality, and health care costs. Infection control experts advocate using maximal sterile barriers to reduce the incidence of these infections. Low compliance rates suggest that clinicians are not convinced or are not aware that available data support adopting this more cumbersome, time-consuming, and relatively more expensive t...

Recent observations of atmospheric neutrinos and especially their zenithangle dependence , strongly suggest that muon neutrinos maximally mix with the tau neutrinos. Motivated by this observation and recent theoretical work on neutrino mass models , we explored 3 the implications of imposing the constraint that two neutrino flavors (which for definiteness we take to be νμ and ντ ) are similarly...

Butachlor (BUT) is a chloroacetanilide herbicide widely applied to rice paddies to control annual grass and broad-leaf weeds. A BUT-degrading bacterial strain (PK) was isolated from paddy soils. Biochemical and 16S rRNA sequencing characteristics confirmed the strain as Pseudomonas aeruginosa (99% resemblance). The isolate dissipated BUT (100 μg/mL) in an M9 liquid medium with a rate of 0.5 ± 0...

Sterile endophthalmitis appears as an infrequent complication of intravitreal injections and seems to develop mainly in the context of the off-label use of drugs that have not been conceived for intravitreous administration. The aetiology of sterile endophthalmitis, independently of the administered drug, remains uncertain and a multifactorial origin cannot be discarded. Sterile inflammation se...

Preparation • Introduce yourself to the patient and explain what you are doing and why. If possible, provide privacy. • Position the patient comfortably and make sure the surrounding area is clean and tidy before you start. • Check the patient’s care notes to update yourself on any changes in the patient’s condition and to make sure the dressing is due to be changed. • Wash your hands and put o...
