BACKGROUND At present, the use of ventilator support is an important part of treatment in ICU patients. However, aside from its well-known advantages, the use of these devices is also associated with complications, the most important of which is pulmonary infection (PI). PI has a high rate of morbidity and mortality. OBJECTIVES This study aimed to evaluate the prevalence of PI in mechanically...

The aim of this study was to determine the prevalence of BVDV infection and existence of persistently infected (PI) cattle in the Trakya region. In total, 260 samples of leukocytes were isolated from dairy cows (65 samples) and breeding bulls (65 samples) and also from cows and bulls in slaughterhouses (65 samples from each). After two blind passages in foetal bovine kidney (FBK) cell culture, ...

Background: Fungal corneal ulcer is the most dangerous and challenging type of infective keratitis.  Since most of the ophthalmic antifungal drops are scarce and expensive in developing countries, attempts have been made to study fungicidal property of some readily available antiseptic agents as a substitute.  Povidone iodine (PI) and chlorhexidine gluconate (CHx) has been postulated to be effe...

for a ring endomorphism $alpha$ and an $alpha$-derivation $delta$, we introduce a concept, so called skew $pi$-armendariz ring, that is a generalization of both $pi$-armendariz rings, and $(alpha,delta)$-compatible skew armendariz rings. we first observe the basic properties of skew $pi$-armendariz rings, and extend the class of skew $pi$-armendariz rings through various ring extensions. we nex...

STUDY DESIGN Retrospective case series. OBJECTIVE To investigate which sagittal parameters contribute to a normal sagittal vertical axis (SVA) when there is a pelvic incidence-lumbar lordosis (PI-LL) mismatch >10° following adult spinal deformity (ASD) correction. METHODS We performed a retrospective review of ASD patients with >5 levels fused. Sagittal measurements between cohorts of posto...

Two intein endonucleases, denoted PI- Pko I and PI- Pko II, in the DNA polymerase gene of the hyperthermophilic archaeon Pyrococcus kodakaraensis KOD1 were expressed in Escherichia coli and the recombinant endonucleases were characterized. Both endonucleases were thermostable and cleaved their intein-less DNA sequences leaving four base 3'-hydroxyl overhangs. PI-Pko I exhibited 22 times higher ...
