Biotinylation Assay to Determine LFA-1 Recycling in Motile T-Lymphocytes
The cycles of internalization of the cell surface β2 integrin receptor lymphocyte function-associated antigen 1 (LFA-1) and its re-exposure on the plasma membrane are important for T-cell trafficking. Biotinylation of cells enables to measure surface expression of receptors, and after reducing surface biotin with reducing buffer, enables to measure the internalization of receptors. Here, by using
Geographic patterns of mtDNA and Z-linked sequence variation in the Common Chiffchaff and the ‘chiffchaff complex’
The Common Chiffchaff Phylloscopus collybita is an abundant, polytypic Palearctic bird. Validity of some of its subspecies is controversial and birds from some parts of the species range remain unclassified taxonomically. The relationships among populations from different geographic areas have not been sufficiently explored with molecular data. In this study we analyzed the relationships among the
Anti-EF-Tu IgG titers increase with age and may contribute to protection against the respiratory pathogen Haemophilus influenzae
Non-typeable Haemophilus influenzae (NTHi) is a pathogen that commonly colonizes the nasopharynx of preschool children, causing opportunistic infections including acute otitis media (AOM). Patients suffering from chronic obstructive pulmonary disease (COPD) are persistently colonized with NTHi and occasionally suffer from exacerbations by the bacterium leading to increased morbidity. Elongation-fa

A Bayesian Network analysis of the probabilistic relations between risk factors in the predisposition to type 2 diabetes
In order to better understand the relations between different risk factors in the predisposition to type 2 diabetes, we present a Bayesian Network analysis of a large dataset, composed of three European population studies. Our results show, together with a key role of metabolic syndrome and of glucose after 2 hours of an Oral Glucose Tolerance Test, the importance of education, measured as the num
Revascularization of Free Skin Grafts Overlying Modified Hughes Tarsoconjunctival Flaps Monitored Using Laser-Based Techniques
Purpose: It has recently been shown that the flap pedicle does not supply blood to a tarsoconjunctival graft in the modified Hughes procedure in patients. This raises questions concerning the rate of revascularization of the free skin graft commonly used to reconstruct the anterior lamella. The aim of this study was, thus, to monitor the course of revascularization in free skin grafts overlying moPurpose: It has recently been shown that the flap pedicle does not supply blood to a tarsoconjunctival graft in the modified Hughes procedure in patients.

Rapid determination of quaternary protein structures in complex biological samples
The understanding of complex biological systems is still hampered by limited knowledge of biologically relevant quaternary protein structures. Here, we demonstrate quaternary structure determination in biological samples using a combination of chemical cross-linking, high-resolution mass spectrometry and high-accuracy protein structure modeling. This approach, termed targeted cross-linking mass sp

A New Silicon Drift Detector System for Kaonic Atom Measurements
The kaonic deuterium measurement at J-PARC and DAΦNE will provide a piece of information still missing to the antikaon-nucleon interaction close to threshold, providing valuable information to answer one of the most fundamental problems in hadron physics today - to the yet unsolved puzzle of how the hadron mass is generated. For this a new X-ray detector system has been developed to measure the sh
A low-frequency inactivating AKT2 variant enriched in the finnish population is associated with fasting insulin levels and type 2 diabetes risk
To identify novel coding association signals and facilitate characterization of mechanisms influencing glycemic traits and type 2 diabetes risk, we analyzed 109,215 variants derived from exome array genotyping together with an additional 390,225 variants from exome sequence in up to 39,339 normoglycemic individuals from five ancestry groups. We identified a novel association between the coding var

A new radiographic method for evaluating the degree of sliding in devices used in hip-fracture surgery
Purpose: To find a practical method for estimating the degree of sliding that occurs in screw-plate devices used in hip-fracture surgery. Greater understanding of the sliding mechanisms in different fracture types should improve surgical technique and reduce the failure rate. Methods and Results: In dynamic screw-plate devices, the lag screw slides inside the barrel of the plate. A recent innovati
The kaonic atoms research program at DAΦNE : Overview and perspectives
The interaction of antikaons with nucleons and nuclei in the low-energy regime represents an active research field in hadron physics with still many important open questions. The investigation of light kaonic atoms is, in this context, a unique tool to obtain precise information on this interaction. The energy shift and broadening of the lowest-lying states of such atoms, induced by the kaon-nucle

Generation of an induced pluripotent stem cell line (CSC-46) from a patient with Parkinson's disease carrying a novel p.R301C mutation in the GBA gene
Mutations in the glucocerebrosidase (GBA) gene have been associated with the development of Parkinson's disease (PD). An induced pluripotent stem cell (iPSC) line was generated from a 60-year old patient diagnosed with PD and carrying a new mutation variant p.R301C in GBA. Using non-integrating Sendai virus-based technology, we utilized OCT3/4, SOX2, c-MYC and KLF4 transcription factors to reprogr

Return to work after early repair of acute traumatic rotator cuff tears
Background: Lost workdays following rotator cuff repair is not well-studied in the literature. We aimed to define the time away from work following early arthroscopic repair of acute traumatic rotator cuff tears and compare it with the recommendations of the American Medical Disability Advisor (MD Guidelines) and The Swedish Social Insurance Agency. Methods: Thirty-two consecutive working patients
