Peptidylarginine Deiminases Present in the Airways During Tobacco Smoking and Inflammation can Citrullinate the Host Defense Peptide LL-37 Resulting in Altered Activities.

Bacterial colonization of the lower respiratory tract is frequently seen in COPD and may cause exacerbations leading to deterioration of the disease. An important part of the innate lung immunity is antimicrobial peptides, not least the cathelicidin hCAP-18/LL-37. Peptidylarginine deiminases (PADI) posttranslationally modifies proteins by converting cationic peptidylarginine residues to neutral pe

Response of ericoid mycorrhizal colonization and functioning to global change factors

Here, we investigated effects of increased atmospheric CO2 concentration, increased temperatures, and both factors in combination on ericoid mycorrhizal colonization, mycorrhizal functioning and below-ground carbon allocation in a subarctic forest understorey, to evaluate the hypothesis that photosynthesis is a primary driver for mycorrhizal colonization. Treatment effects on ecosystem processes w

Hydrolysis of microcrystalline cellulose by cellobiohydrolase I and endoglucanase II from Trichoderma reesei: Adsorption, sugar production pattern, and synergism of the enzymes

Microcrystalline cellulose (10 g/L Avicel) was hydrolysed by two major cellulases, cellobiohydrolase I (CBH I) and endoglucanase II (EG II), of Trichoderma reesei. Two types of experiments were performed, and in both cases the enzymes were added alone and together, in equimolar mixtures. In time course studies the reaction time was varied between 3 min and 48 h at constant temperature (40degreesC)

Structure of needs among persons with schizophrenia

Background The importance of needs assessment for service development has been widely recognised. Several studies have focused on the associations between ratings of needs by patients and staff and have found clear differences, especially concerning the unmet needs. Methods The present study is part of a Nordic Multicentre study that investigates the life and care of outpatients with a schizophren

Crystal structure and biophysical properties of Bacillus subtilis BdbD: An oxidizing thiol:disulfide oxidoreductase containing a novel metal site

BdbD is a thiol: disulfide oxidoreductase (TDOR) from Bacillus subtilis that functions to introduce disulfide bonds in substrate proteins/peptides on the outside of the cytoplasmic membrane and, as such, plays a key role in disulfide bond management. Here we demonstrate that the protein is membrane-associated in B. subtilis and present the crystal structure of the soluble part of the protein lacki

Initial experiments concerning quantum information processing in rare-earth-ion doped crystals

In this paper initial experiments towards constructing simple quantum gates in a solid state material are presented. Instead of using specially tailored materials. the aim is to select a subset of randomly distributed ions in the material. which have the interaction necessary to control each other and therefore can be used to do quantum logic operations. The experimental results demonstrate that p

The Effect of Baseline Testosterone on the Efficacy of Degarelix and Leuprolide: Further Insights From A 12-Month, Comparative, Phase III Study in Prostate Cancer Patients

OBJECTIVE To investigate the effects of baseline testosterone on testosterone control and prostate-specific antigen (PSA) suppression using data from a phase III trial (CS21) comparing degarelix and leuprolide in prostate cancer. METHODS In CS21, patients with histologically confirmed prostate cancer (all stages) were randomized to degarelix 240 mg for 1 month followed by monthly maintenance doses

Ethanol inhibits the peak of muscarinic receptor-stimulated formation of inositol 1,4,5-trisphosphate in neuroblastoma SH-SY5Y cells

The effect of ethanol on muscarinic receptor-stimulated formation of inositol 1,4,5-trisphosphate was studied in human neuroblastoma SH-SY5Y cells. Stimulation with carbachol induced a biphasic increase of inositol 1,4,5-triphosphate with an initial peak after 10 sec declining to a plateau phase of elevation above basal levels, which was sustained for at least 5 min in the presence of agonist. The

Multi-component chemical analysis of gas mixtures using a continuously tuneable lidar system

Differential absorption lidar (DIAL) measurements are usually made on single compounds by alternately switching the wavelength between on and off a resonance line. The selection of more than two wavelengths is a mathematical necessity for simultaneous measurement of multiple species or for resolving interference effects between a compound of interest and a background gas such as water vapour or ca

BRCA1-positive patients are small for gestational age compared with their unaffected relatives

The BRCA1 gene is thought to exert its main function early in life. We, therefore, studied the effects of BRCA1 mutations on birth weight and birth length. This was carried out by comparing 33 women with and without mutations. Birth weight and length were obtained from a self-administered questionnaire. BRCA1 mutations carriers had a significantly lower birth weight (P = 0.0041) compared with non-

Complex telomere-associated repeat units in members of the genus Chironomus evolve from sequences similar to simple telomeric repeats

The dipteran Chironomus tentans has complex tandemly repeated 350-bp DNA sequences at or near the chromosome ends. As in Drosophila melanogaster, short simple repeats with cytosines and guanines in different strands have never been observed. We were therefore interested in learning whether the Chironomus repeats could have evolved from simple sequence telomeric DNA, which might suggest that they c

Regional variation in appearance of vascular contractile endothelin-B receptors following organ culture

OBJECTIVE: The aim of this study was to investigate the appearance of contractile endothelin (ET)-B receptors following organ culture in different vascular regions. METHOD: The contractile responses of vascular smooth muscle induced by ET-1 and the selective ETB receptor agonist sarafotoxin 6c (S6c) were investigated in circular segments representing eight vascular regions in the rat (aorta, femor
