Delayed identification of patients requiring admission to extended care facilities (ECFs) can lead to greater healthcare costs through an increased length of hospital stay (LOHS). Previous studies of hip and knee arthroplasty identified factors associated with a likely discharge to an ECF. These issues have not been extensively studied for major hindfoot procedures. We conducted a retrospective review of 198 cases treated during a 3-year period to identify the risk factors for an extended LOHS and ECF admission after ankle arthrodesis, triple arthrodesis, pantalar arthrodesis, and subtalar arthrodesis...

In biological environments, the surface of nanoparticles (NPs) are modified by protein corona (PC) that determines their biological behavior. Unfortunately, in vitro tests still give different PC than in vivo tests causing in vitro-in vivo discrepancy; hence, in vitro studies are not indicative for the NPs' behavior in vivo. Here is demonstrated that PC in vitro is strongly influenced by the type of extracellular fluid (ECF), blood or lymph, by their high and low flow conditions and transitions between ECFs, and a combination of these parameters...

Amino acids have crucial roles in central metabolism, both anabolic and catabolic. To elucidate these roles, steady-state concentrations of amino acids alone are insufficient, as each amino acid participates in multiple pathways and functions in a complex network, which can also be compartmentalized. Stable Isotope-Resolved Metabolomics (SIRM) is an approach that uses atom-resolved tracking of metabolites through biochemical transformations in cells, tissues, or whole organisms. Using different elemental stable isotopes to label multiple metabolite precursors makes it possible to resolve simultaneously the utilization of these precursors in a single experiment...

The ECF sigma family was identified 23 years ago as a distinct group of σ(70)-like factors. ECF sigma factors have since emerged as a major form of bacterial signal transduction that can be grouped into over 50 phylogenetically distinct subfamilies. Advances in our understanding of these sigma factors and the signaling pathways governing their activity have elucidated conserved features as well as aspects that have evolved over time. All ECF sigma factors are predicted to share a common streamlined domain structure and mode of promoter interaction...

Bacterial toxin/antitoxin (TA) systems have received increasing attention due to their prevalence, diverse structures, and important physiological functions. In this study, we identified and characterized a type II TA system in a soil bacterium Pseudomonas putida KT2440. This TA system belongs to the MqsR/MqsA family. We found that PP_4205 (MqsR) greatly inhibits cell growth in P. putida KT2440 and Escherichia coli, the antitoxin PP_4204 (MqsA) neutralizes the toxicity of the toxin MqsR, and the two genes encoding them are co-transcribed...

Cell-surface signaling (CSS) is a signal transfer system that allows Gram-negative bacteria to detect environmental signals and generate a cytosolic response. These systems are composed of an outer membrane receptor that senses the inducing signal, an extracytoplasmic function sigma factor (σ(ECF)) that targets the cytosolic response by modifying gene expression and a cytoplasmic membrane anti-sigma factor that keeps the σ(ECF) in an inactive state in the absence of the signal and transduces its presence from the outer membrane to the cytosol...

A hierarchical mesoporous carbon foam (ECF) with an interconnected micro-/mesoporous architecture was prepared and used as a binder-free, low-cost, high-performance anode for lithium ion batteries. Due to its high specific surface area (980.6 m(2)/g), high porosity (99.6%), light weight (5 mg/cm(3)) and narrow pore size distribution (~2 to 5 nm), the ECF anode exhibited a high reversible specific capacity of 455 mAh/g. Experimental results also demonstrated that the anode thickness significantly influence the specific capacity of the battery...

The ability to identify and quantify small molecule metabolites derived from gut microbial-mammalian cometabolism is essential for the understanding of the distinct metabolic functions of the microbiome. To date, analytical protocols that quantitatively measure a complete panel of microbial metabolites in biological samples have not been established but are urgently needed by the microbiome research community. Here, we report an automated high-throughput quantitative method using a gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) platform to simultaneously measure over one hundred microbial metabolites in human serum, urine, feces, and Escherichia coli cell samples within 15 min per sample...

The main objective of this work is to simulate the X-ray scattered spectra by different pediatric phantoms (simulation of children subjected to barium meal procedures) to calculate an energy correction factor (ECF) to the reading of thermoluminescent dosimeters (TLDs). To perform this evaluation, the TLDs were positioned over three areas in two occupational workers: eyes, thyroid and hands. The Geant4 toolkit was used to define the spectra collected by TLDs, making possible to calculate the ECF. This work was developed in two stages: (1) evaluation of scattered spectra by different standard phantoms (newborn, 1, 5 and 10 years old); (2) definition of the ECF to the absorbed energy by each TLD...

Established cardiac fibrosis (ECF) with symptomatic heart failure preserved ejection fraction represents an ever-increasing segment of the hypertensive population. The regression of ECF with attendant improvement in myocardial stiffness and symptomatic failure represents an unmet health care need. Is the regression of ECF in hypertensive heart disease feasible and will stiffness and symptomatic failure be improved? What is the cellular/molecular signaling involved in its regression? What incremental knowledge is needed to proceed effectively? These issues are addressed in this Review...

BACKGROUND: Tumour necrosis factor alpha (TNF-α) is a cytokine elevated in inflammatory bowel disease enterocutaneous fistula (IBD ECF). Dendritic cells are antigen presenting cells that orchestrate the immune responses and regulate the production of cytokines by immune cells including T cells. No study to date has assessed the level of TNF-α or the presence of dendritic cells in non-IBD ECF. The aim of this study was to assess the inflammatory activity, with a particular emphasis on TNF-α in non-IBD ECF when compared with control small bowel tissue...

Multidrug resistance-associated proteins (MRPs) and organic anion transporters (OATs) are expressed on the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCSFB), preventing the entry of or the pumping out of numerous molecules. Fluconazole is widely used to treat fungal meningoencephalitis. The effect of these transporters on the distribution of fluconazole in the brain is unclear. We used microdialysis to compare the distribution of fluconazole in the rat brain with and without co-administration of probenecid, a MRP and OAT inhibitor...

BACKGROUND: Postoperative chemoradiation and perioperative chemotherapy using epirubicin/cisplatin/5-fluorouracil (ECF) represent two standards of care for resectable gastric cancer. In the TOPGEAR (Trial Of Preoperative therapy for Gastric and Esophagogastric junction AdenocaRcinoma) trial, we hypothesized that adding preoperative chemoradiation to perioperative ECF will improve survival; however, the safety and feasibility of preoperative chemoradiation have yet to be determined. METHODS: TOPGEAR is an international phase III trial in which patients with adenocarcinoma of the stomach were randomized to perioperative ECF alone or with preoperative chemoradiation...

In Tanzania, control of East Coast fever (ECF) has predominantly relied on tick control using acaricides and chemotherapy, little on ECF vaccination, and very little on dissemination regarding animal immunization. In this paper, the prevalence, control measure, and tolerance of Tanzania Shorthorn Zebu (TSHZ) cattle to ECF are reviewed. In addition, the opportunities available for reducing the use of acaricides for the benefit of the farmers in terms of reduction of costs of purchasing acaricides and environmental pollution are described...
