Ratings of age of acquisition of 299 words across 25 languages : is there a cross-linguistic order of words?

We present a new set of subjective age-of-acquisition (AoA) ratings for 299 words (158 nouns, 141 verbs) in 25 languages from five language families (Afro-Asiatic: Semitic languages; Altaic: one Turkic language: Indo-European: Baltic, Celtic, Germanic, Hellenic, Slavic, and Romance languages; Niger-Congo: one Bantu language; Uralic: Finnic and Ugric languages). Adult native speakers reported the a

Gonadotropin-Releasing Hormone and Its Physiological and Pathophysiological Roles in Relation to the Structure and Function of the Gastrointestinal Tract

Background: Gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) are involved in the reproductive cycle and regulate the secretion of sex steroids from the gonads. In mammals, GnRH1 is secreted as a hormone from the hypothalamus, whereas both GnRH1 and GnRH2 are present as neuropeptides in a variety of tissues. This review describes the role of Gn

Haemophilus influenzae Outer Membrane Proteins-Structure, Function and Virulence Mechanisms

Haemophilus influenzae is a Gram-negative bacterium that is classified by the presence or absence of a polysaccharide capsule, termed “typeable” and “non-typeable” H. influenzae (NTHi), respectively. Depending on the capsular polysaccharide composition and antigenicity, typeable isolates are further subdivided into six serotypes designated a–f. H. influenzae type b (Hib) has been the most common s

Vocational outcome 6–15 years after a traumatic brain injury

Primary objective: To describe vocational outcome 6–15 years after a traumatic brain injury (TBI) among individuals who were productive by working or studying at the time of their TBI and determine associations with variables related to the time of injury and at follow-up. Methods and procedures: Thirty-four individuals with a mild TBI and 45 with a moderate-to-severe TBI were assessed on average

Evaluation of novel control elements by construction of eukaryotic expression vectors

A novel mammalian eukaryotic expression vector for the production of immunoglobulin heavy chain (IgH) genes has been designed. This expression vector contains the variable heavy chain (VH) promoter, the IgH intron enhancer (μE) and the IgH 3' enhancer (3'E). This construct, designated pTIF-1, was stably transfected into the myeloma cell line J558L. A fivefold increase in the expression level of a

Selection of binders from phage displayed antibody libraries using the BIAcore(TM) biosensor

In this report we show that phage displayed antibodies can be selected based on dissociation rate constants, using a BIAcore(TM) biosensor. To demonstrate the principle, two Fab phage stocks displaying antibodies specific for hen egg lysozyme or phenyloxazolone were mixed in a ratio of 1:10 and injected over the biosensor chip containing immobilized lysozyme. Antigen-specific bound phages were elu

Phospholamban inhibitors and a method for increasing coronary flow

A method for obtaining direct dilatation of the coronary arteries by administering a therapeutically effective amount of a phospholamban inhibitor is described. Compounds which are effective in relieving the inhibitory effects of phospholamban on cardiac sarcoplasmic reticulum Ca2+ -ATPase are also described.

Factors that Influence the Biochemical Methane Potential (BMP) Test : Steps towards the Standardisation of BMP Test

Anaerobic digestion (AD) has gained increasing attention nowadays as an approach for both waste treatment and renewable energy generation. Currently, many different types of materials can be used as feedstock for biogas production via AD process, but their biodegradability (based on methane yield, BDCH4) and potential to produce biogas might vary significantly, and these properties are key paramet

Preparations for retirement in Sweden: Migrant perspectives

Migrants as a group are recognised as being at risk of receiving low retirement pensions. Income over a lifetime is the principle for calculating pension rights. We have interviewed a group of migrants about their retirement preparations. Our results show that there are obstacles that obstruct migrants from entering the Swedish labour market, which will greatly influence future pension rights. The

Monitoring changes in membrane polarity, membrane integrity, and intracellular ion concentrations in Streptococcus pneumoniae using fluorescent dyes

Membrane depolarization and ion fluxes are events that have been studied extensively in biological systems due to their ability to profoundly impact cellular functions, including energetics and signal transductions. While both fluorescent and electrophysiological methods, including electrode usage and patch-clamping, have been well developed for measuring these events in eukaryotic cells, methodol

Biofilm formation enhances fomite survival of Streptococcus pneumoniae and Streptococcus pyogenes

Both Streptococcus pyogenes and Streptococcus pneumoniae are widely thought to rapidly die outside the human host, losing infectivity following desiccation in the environment. However, to date, all literature investigating the infectivity of desiccated streptococci has used broth-grown, planktonic populations. In this study, we examined the impact of biofilm formation on environmental survival of

Sensitization of Staphylococcus aureus to methicillin and other antibiotics in vitro and in vivo in the presence of HAMLET

HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a protein-lipid complex from human milk with both tumoricidal and bactericidal activities. HAMLET exerts a rather specific bactericidal activity against some respiratory pathogens, with highest activity against Streptococcus pneumoniae, but lacks activity against most other bacterial pathogens, including Staphylococci. Still, ion trans

Neural tolerance of the non-ionic dimers iodixanol and iotrolan and the non-ionic monomer iopamidol during myelography in non-anaesthetised rabbits

PURPOSE: The neural tolerance of the recently introduced dimer iodixanol (320 g I/l) was compared with that of the dimer iotrolan (300 g I/l) and of the monomer iopamidol (300 g I/l), both used in clinical myelography.MATERIAL AND METHODS: Non-anaesthetised rabbits were injected into the cisterna magna with Ringer's solution (control) or contrast media (CM) at doses of 1.0 or 0.5 ml/kg b.w. The be

Relaxation dynamics of SF6 studied by energy resolved electron ion coincidence technique

The mass spectra from the SF6 molecule acquired by energy-resolved electron ion coincidence (EREICO) technique using (1t1g + [5t1u,1t2u]), (3eg + 1t2g), 4t1u, and 5a1g electrons after both valence and S 2p−1 6a1g core excitation reveal a strong selectivity in the dissociation from these states. From the comparison of the obtained spectra, the influence of the core-excited state in the relaxation p
