BACKGROUND Ligamentum flavum (LF) hypertrophy is a common cause of lumbar spinal stenosis and is thought to be degeneration-driven. Developmental spinal stenosis (DSS) is characterized by pre-existing narrowed spinal canals and is likely a developmental problem that occurs in childhood. In these cases, the LF may demonstrate different characteristics as compared to degeneration-driven stenosis....

Lactoferrin receptor (LfR) is expressed in most mammalian tissues including placental trophoblasts and is presumed to mediate the internalization of lactoferrin (Lf). However, the physiological significance of trophoblast LfR is not understood. Using a cytotrophoblast cell model (BeWo) we demonstrated that transfection with LfR siRNA significantly decreased apo- but not holo-Lf uptake compared ...

the aim of this study was to characterize the effect of typhoid fever on pharmacokinetic parameters of levofloxacin (lf) and compare the pharmacokinetic parameters of the said antibiotic in healthy human volunteers and patients with typhoid fever. total of 12 subjects were divided into two groups “a” (healthy volunteers) and “b” (typhoid patients). single oral dose of lf 500 mg was given and 5 ...

Review and classification of electric load forecasting (LF) techniques based on artificial neural networks (ANN) is presented. A basic ANNs architectures used in LF reviewed. A wide range of ANN oriented applications for forecasting are given in the literature. These are classified into five groups: (1) ANNs in short-term LF, (2) ANNs in mid-term LF, (3) ANNs in long-term LF, (4) Hybrid ANNs in...

In this paper we study homogenization problem for strong Markov processes on Rd having infinitesimal generators Lf(x)=?Rd(f(x+z)?f(x)???f(x),z?1{|z|?1})k(x,z)?(dz)+?b(x),?f(x)?,f?Cb2(Rd) in periodic media, where ? is a nonnegative measure that does not charge the origin 0, satisfies ?Rd(1?|z|2)?(dz)<? and can be singular with respect to Lebesgue Rd. Under proper scaling show scaled converge wea...

—Quantifying lipofuscin (LF), a metabolic byproduct that accumulates in postmitotic cells, serves as one of the principal approaches for aging crustaceans, but the accuracy of this method remains an important issue. Here, we quantified LF accumulation as a function of chronological age and temperature (degree-days) in an economically important crustacean, the blue crab Callinectes sapidus, to t...

Isolated rat hepatocytes bind and internalize bovine lactoferrin (Lf) and its bound iron in a Ca2+-dependent manner. In this study, we determined if one or both halves of Lf (N- and C-lobes) were responsible for the interaction of Lf with hepatocytes. We isolated three tryptic fragments of bovine Lf. Cleavage at Arg284-Ser285 generated two fragments: N-terminal pp36 that contained 80% of Lf N-l...
