BACKGROUND & AIMS: Esophageal retention is typically evaluated by timed barium esophagram in patients treated for achalasia. Esophageal bolus clearance can also be evaluated using high-resolution impedance manometry. We evaluated the associations of conventional and novel high-resolution impedance manometry metrics, esophagram, and patient-reported outcomes (PRO) in achalasia. METHODS: We performed a prospective study of 70 patients with achalasia (20-81 years old, 30 female) treated by pneumatic dilation or myotomy who underwent follow-up evaluations from April 2013 through December 2015 (median 12 months after treatment; range, 3-183 months)...

The chirality (n,m) determines all structures and properties of a single-walled carbon nanotube (SWNT), therefore, accurate and convenient (n,m) assignments are vital in nanotube-related science and technology. Previously, a so-called Kataura plot that protracts the excitonic transition energies (Eii's) of SWNTs with various (n,m) with respect to the tube diameter (dt) has been widely utilized by researchers in the nanotube community for all (n,m)-related studies. However, the facts that both Eii and the calculated dt are subject to interactions with the environments make it inconvenient to accurately determine the (n,m) under complex environments...

The glucose/mannose-phosphotransferase system (PTS) permease EII(Man) encoded by manLMN in the dental caries pathogen Streptococcus mutans has a dominant influence on sugar-specific, CcpA-independent catabolite repression (CR). Mutations in manL affect energy metabolism and virulence-associated traits, including biofilm formation, acid tolerance, and competence. Using promoter::reporter fusions, expression of the manLMN and the fruRKI operons, encoding a transcriptional regulator, a fructose-1-phosphate kinase and a fructose-PTS permease EII(Fru), respectively, was monitored in response to carbohydrate source and in mutants lacking CcpA, FruR, and components of EII(Man) Expression of genes for EII(Man) and EII(Fru) was directly regulated by CcpA and CR, as evinced by in vivo and in vitro methods...

PURPOSE: To define the risk for type II endoleak (EII) after endovascular aneurysm repair (EVAR) based on preoperative anatomical characteristics. METHODS: Between January 2008 and December 2015, 189 patients (mean age 78.4±7.6 years; 165 men) underwent standard EVAR. Mean aneurysm diameter was 5.7±0.7 cm and mean volume 125.2±45.8 cm(3). Patients were assigned to the "at-risk" group (n=123, 65%) when at least one of the following criteria was present: patency of a >3-mm inferior mesenteric artery (IMA), patency of at least 3 pairs of lumbar arteries, or patency of 2 pairs of lumbar arteries and a sacral artery or accessory renal artery or any diameter patent IMA; otherwise, patients were entered in the "low-risk" group (n=66, 35%)...

Matthew J Piggott, Paul V Attwood
The synthesis and chemistry of the lesser-known phosphoamino acids, O-phosphohydroxylysine, O-phosphohydroxyproline, N (1)-phosphotryptophan and S-phosphocysteine are described in detail. In addition, where anything at all is known, the biological synthesis, occurrence and functions of these phosphoamino acids are described. Of these phosphoamino acids, only N (1)-phosphotryptophan has not been reported to occur in proteins; however, apart from the roles of S-phosphocysteine in the sugar transporter component (EII) and in catalysis by protein phosphotyrosine phosphatase, little is currently known about the biological roles of the phosphoamino acids when they occur as post-translational modifications...

BACKGROUND: Intraprocedural aneurysm sac embolization (embo-EVAR) during endovascular abdominal aneurysm repair (EVAR) using coils and fibrin glue is a technique for preventing type II endoleak (EII). Our aim is to evaluate feasibility, safety and clinical outcome of this promising approach. MATERIALS AND METHODS: A retrospective clinical case analysis of 72 patients who underwent EVAR during the period 2011-2014. Two groups were compared at 6 and 12 months follow-up with contrast media computed tomography scan and contrast-enhanced ultrasound (CEUS) imaging: consecutively, 36 patients (group A) treated with classic EVAR and 36 patients (group B) treated with embo-EVAR...

The nitrogen phosphotransferase system (PTS(Ntr)) is a regulatory cascade present in many bacteria, where it controls different functions. This system is usually composed of three basic components: enzyme I(Ntr) (EI(Ntr)), NPr, and EIIA(Ntr) (encoded by the ptsP, ptsO, and ptsN genes, respectively). In Legionella pneumophila, as well as in many other Legionella species, the EIIA(Ntr) component is missing. However, we found that deletion mutations in both ptsP and ptsO are partially attenuated for intracellular growth...

Novel barley (1 → 3, 1 → 4)-β-glucan endohydrolases with increased thermostability. Rapid and reliable degradation of (1 → 3, 1 → 4)-β-glucan to produce low viscosity wort is an essential requirement for malting barley. The (1 → 3, 1 → 4)-β-glucan endohyrolases are responsible for the primary hydrolysis of cell wall β-glucan. The variation in β-glucanase genes HvGlb1 and HvGlb2 that encode EI and EII, respectively, were examined in elite and exotic germplasm. Six EI and 14 EII allozymes were identified, and significant variation was found in β-glucanase from Hordeum vulgare ssp...

Streptococcus pneumoniae harbors a significant number of transporters, including phosphotransferase (PTS) systems, allowing the bacterium to utilize a number of different carbohydrates for metabolic and other purposes. The genes encoding for one PTS transport system in particular (EII(fuc) ) are found within a fucose utilization operon in S. pneumoniae TIGR4. Here, we report the three-dimensional structures of IIA(fuc) and IIB(fuc) providing evidence that this PTS system belongs to the EII(man) family. Additionally, the predicted metabolic pathway for this distinctive fucose utilization system suggests that EII(fuc) transports the H-disaccharide blood group antigen, which would represent a novel PTS transporter specificity...

BACKGROUND: This study aimed to establish the changes in the incidence and characteristics of iodine-induced hyperthyroidism (II-Hyper) and iodine-induced hypothyroidism (II-Hypo) in the two-year period before and the 10-year period after the increase in mandatory salt iodization from the previous 10 mg/kg of potassium iodide to 25 mg/kg in 1999. Furthermore, the aim was to determine the duration of treatment in II-Hyper patients, since no data regarding severity and treatment of II-Hyper with respect to iodine supply are available...

Barley (1→3,1→4)-β-glucan endohydrolases (β-glucanases; EI and EII) are primarily responsible for hydrolyzing high molecular weight (1→3,1→4)-β-glucans (β-glucan) during germination. Incomplete endosperm modification during malting results in residual β-glucan that can contribute to increased wort viscosity and beer chill haze. Four newly identified forms of EI and EII and the reference enzymes EI-a and EII-a were expressed in Escherichia coli, and the recombinant proteins were characterized for enzyme kinetics and thermostability...

Biosynthesis of polysaccharide hyaluoronic acid (HA) by Streptococcus zooepidemicus is a carbon-intensive process. The carbon flux and factor(s) restricting HA yield were not well understood. Here, we investigated the function of genes involved in sucrose metabolism and identified targets limiting HA yield, which were exploited to construct efficient S. zooepidemicus strains for HA production. The sucrose uptake was addressed by deletion of scrA and scrB, which encodes sucrose-PTS permease and sucrose-6-phosphate hydrolase, respectively...

The Group A Streptococcus (GAS, Streptococcus pyogenes) is a Gram-positive human pathogen that must adapt to unique host environments in order to survive. Links between sugar metabolism and virulence have been demonstrated in GAS, where mutants in the phosphoenolpyruvate-dependent phosphotransferase system (PTS) exhibited Streptolysin S (SLS)-mediated hemolysis during exponential growth. This early onset hemolysis correlated with an increased lesion size and severity in a murine soft tissue infection model when compared with parental M1T1 MGAS5005...

Upon exposure to exogenous pediocin-like bacteriocins, immunity proteins specifically bind to the target receptor of the mannose phosphotransferase system components (man-PTS IIC and IID), therefore preventing bacterial cell death. However, the specific recognition of immunity proteins and its associated target receptors remains poorly understood. In this study, we constructed hybrid receptors to identify the domains of IIC and/or IID recognized by the immunity protein PedB, which confers immunity to pediocin PA-1...

Experimental band structure analyses of single-walled carbon nanotubes have not yet been reported, to the best of our knowledge, except for a limited number of reports using scanning tunnelling spectroscopy. Here we demonstrate the experimental determination of the excitonic band structures of single-chirality single-walled carbon nanotubes using their circular dichroism spectra. In this analysis, we use gel column chromatography combining overloading selective adsorption with stepwise elution to separate 12 different single-chirality enantiomers...
