Energy-coupling factor (ECF) transporters are a recently discovered family of primary active transporters for micronutrients and vitamins, such as biotin, thiamine, and riboflavin. Found exclusively in archaea and bacteria, including the human pathogens Listeria, Streptococcus, and Staphylococcus, ECF transporters may be the only means of vitamin acquisition in these organisms. The subunit comp...

Enterocutaneous fistulas (ECF) are a difficult and costly surgical complication to manage. The standard treatment of nil per os (NPO) and total paraenteral nutrition (TPN) is not well tolerated by patients. TPN is also known for complications associated with long term central venous catheterization and for high cost of prolonged hospital stay. We present two low output ECF cases successfully tr...

BACKGROUND Bioimpedance analysis (BIA) is well established to assess body composition. Agreements between single- and multi-frequency bioimpedance (SF-BIA, MF-BIS) measurements in subjects undergoing 6 or 3 times/week hemodialysis (HD) were analyzed. METHODS Total body water (TBW) and intra- and extracellular fluid (ICF, ECF) of subjects enrolled in the Frequent Hemodialysis Network (FHN) Dai...

Energy-coupling factor (ECF) transporters mediate uptake of micronutrients in prokaryotes. The transporters consist of an S-component that binds the transported substrate and an ECF module (EcfAA'T) that binds and hydrolyses ATP. The mechanism of transport is poorly understood but presumably involves an unusual step in which the membrane-embedded S-component topples over to carry the substrate ...

Gastric cancer is most chemosensitive among gastrointestinal tumors. However, the role of chemotherapy in advanced disease and its advantage over best supportive care has been adequately addressed only in the last decade. First generation regimens, such as 5-Fluorouracil (5-FU), Doxorubicin, Mitomycin C (FAM) have been used until early 90's, when evidence from randomized studies came up in favo...

BACKGROUND We assessed the effectiveness of perioperative MAGIC-style chemotherapy in our series focused on the tumor regression grade and survival rate. METHODS We conducted a retrospective study of 53 patients following a perioperative regimen of epirubicin, cisplatin, and fluorouracil or capecitabine (ECF/X). Forty-four (83 %) neoplasias were located in the stomach and 9 (17 %) were locate...

INTRODUCTION Peripheral arterial disease, as measured by the ankle-brachial index (ABI), is prevalent among the elderly, and is associated with functional performance, assessed by the 6-minute walk test (6MWT). Executive cognitive function (ECF) impairments are also prevalent in this population, but no existing study has investigated the association between ECF and functional performance in an ...

Eco-certified forestry (ECF) is defined as forest management that incorporates ecological concerns into commercial timber production. In this paper, we link the adoption of ECF practices to shifts in the timber supply function. We use a spatially disaggregated model of southeastern US timber supply to simulate the empirical relationship between variations in the price premium offered for timber...

Purpose This paper seeks to provide empirical insight into how industrialization and technology affect environmental quality in Ghana. Design/methodology/approach Using Ecological Footprint (ECF) as a measure of degradation, the authors employ annual data from World Development Indicators Bank Global Network spanning 1970 2017 apply fully modified least squares (FMOLS) technique. Findings The r...
