The precursors, [ 35S]sulfate and [2- 3H]mannose, were used to study the biosynthesis of keratan sulfate and other oligosaccharides on proteoglycans isolated from Day 8 cultures of chick limb bud chondrocytes. After alkaline borohydride treatment, three fractions with sialic acid were separated by molecular sieve chromatography. The first contained keratan sulfate which was purified by digestion w

This paper presents a symbol time offset estimator for coherent OFDM systems. This estimator exploits both the redundancy in the cyclic prefix and the pilot symbols used for channel estimation. The estimator is robust against frequency offsets and is suitable for use in dispersive channels. We base the estimator on the ML estimator for the AWGN channel. Simulations of an example system indicate a

The aim of this paper is to chart the relevant studies and research questions concerning the relationship between ICTs and Mobility in Everyday Life – a concept defined and delineated in a previous paper An Agenda for ‘Mobility in Everyday Life’ for ICT Researchers (Haddon, 2000a).

High resolution real time heat release analysis will become increasingly important in the future development of engine control systems. The increased demands on efficiency and emissions will put high demands on future engine control. Future engine concepts, for example the HCCI engine concept might crave cylinder pressure based Closed-Loop Combustion Control (CLCC). The analysis of cylinder pressu

Neisseria meningitidis is a normal commensal of human mucous membranes that is no longer considered to be restricted to the nasopharynx. Due to the practice of oral sex, the mucous membranes of the cervix, urethra or anus have become a potential infection site for this bacterium. Inserting an intrauterine device (IUD), can alter the protective barrier of the endocervical mucosa, allowing for bacte

OBJECTIVE: There is great need of biomarkers for research and clinical purposes in COPD. This study explored the relationships between ten putative plasma biomarkers of COPD and physiological measures of reduced lung function. METHODS: FEV(1), FVC, residual volume/total lung capacity (RV/TLC) and CO diffusion capacity (D(L)CO) were assessed in 357 subjects from the Swedish Twin Registry. The l

this study we investigated the effects of gastrectomy (Gx) and of the gastric hormone, ghrelin, on the expression of proteins in brown adipose tissue (BAT) that are thought to be involved in thermogenesis. Heat production in BAT is known to depend upon activation and increased expression of β3-adrenergic receptors (β3-AR) and the consequent up-regulation of uncoupling protein 1 (UCP1). Mice were s

The electronic coupling strength within columns of discotic liquid crystals is investigated using core-level Coexisting well-ordered and disordered regions are identified in thin films of tetra-alkoxy-substituted phthalocyanines with the aid of near edge X-ray absorption fine structure and photoelectron spectroscopies. These different regions Lire used to derive a lower limit for the intermolecula

To investigate whether interstitial cells (ICs) are present in the adult mouse bladder, and what transmitters characterize adjacent nerve fibres, as ICs in human and guinea-pig bladder lie close to nerve fibres but transmitters present in these nerves have not yet been reported. Sections of the bladder wall from 12 adult male mice (six each, aged 3-4 or 18-24 months) were incubated in carboxygenat

1. Fungus-growing termites live in an obligate mutualistic symbiosis with Termitomyces fungi. The functions of the fungal symbiont have been hypothesised to differ between species and to range from highly specific roles of providing plantdegrading enzymes complementary to termite gut enzymes, to non-specific roles of providing protein-rich food to the termites. 2. Termite species with unspecialise

Pseudohyphae formation by Candida albicans blastoconidia, as seen in vaginal smears, is a phenotypical change commonly assumed to mean fungal invasiveness, i.e. not mere colonization. C. albicans forms germ tubes in vitro in the presence of serum. In our search for inhibitory components of germ tube formation, we decided to study fibrinogen. The inhibition of germ tube formation by clinical isolat

Electron-ion-ion coincidence measurements carried out at discrete resonances near the N 1s threshold in ammonia are reported. The measured coincidence spectra show clear alignment of the molecule upon resonant core-electron excitation. The coincidence data are analyzed to extract information about the molecule in the excited state by simulating the alignment and the dissociation processes. Dynamic

Alcohol dependence is a devastating illness affecting a large population, and new pharmacological treatments with good efficacy are greatly needed. One potential candidate is varenicline, a smoking cessation agent with partial agonist action at α4 β2 nicotinic acetylcholine receptors.

Exciton dynamics in alternating copolymer/fullerene solar cell blends have been investigated using femtosecond transient absorption spectroscopy. The acceptor concentrations have been varied over a wide range. Experimental data, kinetic modeling and simulations, all indicate that the efficiency of exciton conversion to charges is 100% even at acceptor concentrations as low as 20 wt%. The reported

The team behavior literature is ambiguous about the relations between members’ interpersonal processes—task debate and task conflict—and team performance. From a social influence perspective, we show why members’ interpersonal processes determine team performance over time in small groups. Together, over time, dissenting in-group minorities who share information (via debate) with majorities, who s

Molecular docking is a computational approach that predicts interactions between ligands and protein targets based on binding energies. In this study, the potential interactions of 1,8-cineole -one of the dominant components of Eucalyptus globulus oil- with the main protease (Mpro) and macrodomain (MacI) of SARS-CoV-2 were studied by molecular docking. Nine Mpro and four ManI structures available

En hermeneutisk undersökning av hur manlighet skildras i kvinnliga trubadurers minnelyrik från högmedeltida Occitanien. Uppsatsen diskuterar lyrikens kontext och trobairitzernas korpus, för att sedan analysera de 26 dikter som med störst sannolikhet verkligen är skrivna av trobairitzerna. Analysen fokuserar på vilka egenskaper männen i lyriken tillskrivs, hur männen figurerar i förhållande till ly
