In elderly populations, frailty is associated with higher mortality risk. Although many frailty scores (FS) have been proposed, no single score is considered the gold standard. We aimed to evaluate the agreement between a wide range of FS in the English Longitudinal Study of Ageing (ELSA). Through a literature search, we identified 35 FS that could be calculated in ELSA wave 2 (2004-2005). We e...

The discovery of high-temperature superconductivity in iron pnictides raised the possibility of an unconventional superconducting mechanism in multiband materials. The observation of Fermi-surface (FS)-dependent nodeless superconducting gaps suggested that inter-FS interactions may play a crucial role in superconducting pairing. In the optimally hole-doped Ba(0.6)K(0.4)Fe(2)As(2), the pairing s...

introduction: the process of wound healing sets in motion a complex and dynamic series of events, which includes the remodeling of the extracellular matrix degradation of matrix proteins, predominantly collagen fibers, mediated by matrix metalloproteinase (mmps). our aim was to demonstrate whether fibroblasts derived from various strains of human fetal foreskin (fs) and adult skin (as), when cu...

Forward selection (FS) is a step-by-step model-building algorithm for linear regression. The FS algorithm was expressed in terms of sample correlations where Pearson’s product-moment correlation was used. The FS yields poor results when the data contain contaminations. In this article, we propose the use of Spearman’s rank correlation in FS. The proposed method is called FSr. We conduct an exte...

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

This paper reports experiments designed to find the concentrations of internal and external Na and K at which inward and outward furosemide-sensitive (FS) Na and K fluxes are equal, so that there is no net FS movement of Na and K. The red cell cation content was modified by using the ionophore nystatin, varying cell Na (Nai) from 0 to 34 mM (K substitution, high-K cells) and cell K (Ki) from 0 ...

Striatal fast-spiking (FS) interneurons are interconnected by gap junctions into sparsely connected networks. As demonstrated for cortical FS interneurons, these gap junctions in the striatum may cause synchronized spiking, which would increase the influence that FS neurons have on spiking by the striatal medium spiny (MS) neurons. Dysfunction of the basal ganglia is characterized by changes in...

PURPOSE To compare dry eye after small incision lenticule extraction (SMILE) and femtosecond laser-assisted LASIK (FS-LASIK) for correcting myopia. METHODS CENTRAL, Embase and PubMed were searched in November 2016. All randomized controlled trials (RCTs) and prospective cohorts that compared dry eye after SMILE with FS-LASIK were selected. RESULTS Five cohorts and one RCT were identified fo...

Febrile seizures (FS) affect almost 2-5% of children and factors related to an increase susceptibility of children to FS may involve an imbalance of inflammatory cytokines and genetic factors. FS had low morbidity, but may be associated with the occurrence of late chronic epilepsy. Here we describe factors related to FS and its possible correlation with SUDEP.

The widely practiced intra-operative methods for rapid evaluation and detection of sentinel lymph node (SLN) status include frozen section (FS) and touch imprint cytology (TIC). This study optimized the use of TIC and FS in the intra-operative detection of breast SLNs based on the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Three hundred forty-two SLNs were removed from 79 patients...
