BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. METHODS: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20)...

The distribution of DARPP-32 (a phosphoprotein related to the dopamine D1 receptor) has been widely used as a means to clarify the brain regions with dopaminoceptive cells, primarily in representative species of tetrapods. The relationship between dopaminergic and dopaminoceptive elements is frequently analyzed using the catecholamine marker tyrosine hydroxylase (TH). In the present study, by means of combined immunohistochemistry, we have analyzed these relationships in lungfishes, the only group of sarcopterygian fishes represented by 6 extant species that are the phylogenetically closest living relatives of tetrapods...

We report magic angle spinning (MAS) up to 8.5 kHz with a sample temperature below 6 K using liquid helium as a variable temperature fluid. Cross polarization (13)C NMR spectra exhibit exquisite sensitivity with a single transient. Remarkably, (1)H saturation recovery experiments show a (1)H T1 of 21 s with MAS below 6 K in the presence of trityl radicals in a glassy matrix. Leveraging the thermal spin polarization available at 4.2 K versus 298 K should result in 71 times higher signal intensity...

Humoral immunity wanes during healthy ageing, increasing susceptibility to infections in the elderly. In this sense, information about parasite infections and human immunosenescence is scarce. Cystic echinococcosis (CE) is an infectious disease caused by the larval stage of the cestode parasite Echinococcus granulosus, whose prevalence in humans shows an increase with host age. Susceptibility to human CE has been associated with humoral immunity to some extent; and therefore, we have here analyzed the influence of host age on the serological profile of young, middle-aged, and aged patients...

There has been remarkably little attention to using the high resolution provided by genotyping-by-sequencing (i.e. RADseq and similar methods) datasets for assessing relatedness in wildlife populations. A major hurdle is the genotyping error, especially allelic dropout, often found in this type of dataset that could lead to downward-biased, yet precise, estimates of relatedness. Here we assess the applicability of genotyping-by-sequencing datasets for relatedness inferences given their relatively high genotyping error rates...

Back pain is a leading cause of global disability that can arise from vertebral fracture and osteoporosis. While poor general health and obesity are among the strongest risk factors for back pain, there is remarkably little known about how diet influences spinal diseases. Advanced glycation endproducts (AGEs) are implicated in increased fracture risk, yet no studies investigated how dietary AGEs affect spinal health. We tested the hypothesis that high dietary AGE ingestion will diminish vertebral structure and function in a sex- and age-dependent manner...

The development of a sensitive and accurate analytical method for monitoring aminoglycosides in food, environmental, and clinical samples is needed for many purposes. This study found that the responses of sodiated and protonated aminoglycosides in hydrophilic interaction chromatography with tandem mass spectrometry were enhanced upon addition of sodium acetate in methanol (5 mg L(-1) at a flow rate of 0.2 mL min(-1)) as a post-column reagent. The sensitivities of sodiated spectinomycin, kanamycin, gentamicins, neomycin, and amikacin were significantly higher than those of the protonated molecules...

The reaction of a multisite coordination ligand, LH3, with Cu(II) salts and Ln(NO3)3·nH2O in a 1:2:1 stoichiometric ratio in the presence of triethylamine was found to afford a series of one-dimensional heterometallic [{Cu5Ln2(L)2(μ3-OH)4(ClO4)(NO3)3(OH2)5}(ClO4)2(H2O)x]∞ [Ln = Tb(1), Dy(2) and Ho(3), x = 4.25, 5.5, and 5 for 1-3, respectively] coordination polymers. Complexes 1-3 have been characterized by single crystal X-ray crystallography. The detailed study of the magnetic properties has also been performed and compared with the parent [Cu5Ln2] molecular analogues...

With the aim to understand how NGS improves both our assessment of genetic variation within populations and our knowledge on HLA molecular evolution, we sequenced and analysed 8 HLA loci in a well-documented population from sub-Saharan Africa (Mandenka). The results of full-gene NGS-MiSeq sequencing compared to those obtained by traditional typing techniques or limited sequencing strategies showed that segregating sites located outside exon 2 are crucial to describe not only class I, but also class II population diversity...

The two families of Ru(II)-chromene and -chromone complexes isolated in this work represent the first examples of metalated chromene and chromone complexes synthesized through transition-metal mediated cyclization of phenol-tethered ynone. These unprecedented metalated heterocyclic compounds exhibit remarkable features, such as pH-switchable metal-carbon bonding interactions, photo-triggerable release of organic chromone upon visible-light irradiation, and superior antioxidative property to their organic analog (1,4-benzopyrone)...

Zirconium-89 is an emerging radionuclide for positron emission tomography (PET) especially for biomolecules with slow pharmacokinetics as due to its longer half-life, in comparison to fluorine-18 and gallium-68, imaging at late time points is feasible. Desferrioxamine B (DFO), a linear bifunctional chelator (BFC) is mostly used for this radionuclide so far but shows limitations regarding stability. Our group recently reported on fusarinine C (FSC) with similar zirconium-89 complexing properties but potentially higher stability related to its cyclic structure...

Ruminococcus bromii is a dominant member of the human colonic microbiota that plays a 'keystone' role in degrading dietary resistant starch. Recent evidence from one strain has uncovered a unique cell surface 'amylosome' complex that organizes starch-degrading enzymes. New genome analysis presented here reveals further features of this complex and shows remarkable conservation of amylosome components between human colonic strains from three different continents and a R. bromii strain from the rumen of Australian cattle...

The bathypelagic ocean is one of the largest ecosystems on Earth, and sustains half of the ocean's microbial activity. This microbial activity strongly relies on surface-derived particles, but there is growing evidence that the carbon released through solubilisation of these particles may not be sufficient to meet the energy demands of deep ocean prokaryotes. To explore how bathypelagic prokaryotes respond to the absence of external inputs of carbon, we followed the long-term (1 yr) dynamics of an enclosed community...

BACKGROUND: Gastric motility is controlled by the autonomic and enteric nervous systems and by interstitial cells of Cajal (ICCs). Although histamine is known to be released from enterochromaffin-like cells in the gastric mucosa, its regulatory roles in gastric motility are still controversial. Therefore, we investigated the functional roles of histamine in gastric motility. METHODS: Stomach preparations from hamsters were used because the stomach of hamsters can be easily separated into the forestomach and the glandular stomach...

Health damages and the late effects of NS trauma were largely ignored in German-speaking countries. This paper describes how dealing with the late effects of Nazi terror influenced post-war psychiatry in West Germany and thus the development of the psychiatric reform. As part of a greater overview study of the impulses and framework conditions of the reform-orientated development of post-war psychiatry in West Germany, this analysis is based on a thorough literary and documentary analysis. The sources show that publications by Helmut Paul and Herberg [81] as well as Baeyer et al...

Polysaccharides are structurally complex and essential constituents of life, and therefore, studies directed to these kinds of molecules have received scientific attention. Despite an easy availability of Dolichos biflorus Linn and Trachyspermum ammi (Linn) seeds isolation, characterization and antimicrobial studies of polysaccharides derived from these two natural sources have not been investigated. Therefore, we report here isolation of polysaccharides, their purification and characterization from Dolichos biflorus Linn and Trachyspermum ammi (Linn) seeds...

Recombinant chimeric α-amylase (AmyP-Cr) was constructed by a catalytic core of α-amylase (AmyP) from a marine metagenomic library and a starch-binding domain (SBDCr) of α-amylase from Cryptococcus sp. S-2. The molecular fusion did not alter optimum pH, optimum temperature, hydrolysis products, and an ability of preferential and rapid degradation towards raw rice starch, but catalytic efficiency and thermostability were remarkably improved compared with those of the wild-type AmyP. AmyP-Cr achieved the final hydrolysis degree of 61...

Nanostructures with exceptional absorption in the near infrared (NIR) regime are receiving significant attention due to their ability to promote controlled local heating in biological material upon irradiation. Also, such nano-structures have numerous applications in nano-electronics and for bio-exploration. Therefore, significant effort is being put into controlling and understanding plasmonic nanostructures. However, essentially all focus has been on NIR resonant gold nanoparticles and remarkably little attention has been given to nanoparticles of other materials that may have superior properties...

In this paper, MnO2 nanoboxes coated with poly(3,4-ethylenedioxythiophene) film (denoted as MnO2@PEDOT) are investigated as an anode material in lithium-ion batteries. The MnO2 nanoboxes are developed through the surface chemical oxidation decomposition of MnCO3 cubes and the subsequent removal of their remaining cores. PEDOT is coated on the surface of MnO2 nanoboxes via in situ polymerization of 3,4-ethylenedioxythiophene. The charge-discharge tests demonstrate that this special configuration endows the resulting MnO2@PEDOT with remarkable electrochemical performances, that is a reversible capacity of 628 mA h g(-1) after 850 cycles at a current density of 1000 mA g(-1) and a rate capacity of 367 mA h g(-1) at 3000 mA g(-1)...
