A PTIP-PA1 subcomplex promotes transcription for IgH class switching independently from the associated MLL3/MLL4 methyltransferase complex.

Class switch recombination (CSR) diversifies antibodies for productive immune responses while maintaining stability of the B-cell genome. Transcription at the immunoglobulin heavy chain (Igh) locus targets CSR-associated DNA damage and is promoted by the BRCT domain-containing PTIP (Pax transactivation domain-interacting protein). Although PTIP is a unique component of the mixed-lineage leukemia 3

Varisnp, A Benchmark Database For Variations from dbSNP.

For development and evaluation of methods for predicting the effects of variations, benchmark datasets are needed. Some previously developed datasets are available for this purpose, but newer and larger benchmark sets for benign variants have largely been missing. VariSNP datasets are selected from dbSNP. These subsets were filtered against disease-related variants in the ClinVar, UniProtKB/Swiss-

Recovering from a Decade: A Systematic Mapping of Information Retrieval Approaches to Software Traceability

Engineers in large-scale software development have to manage large amounts of information, spread across many artifacts. Several researchers have proposed expressing retrieval of trace links among artifacts, i.e. trace recovery, as an Information Retrieval (IR) problem. The objective of this study is to produce a map of work on IR-based trace recovery, with a particular focus on previous evaluatio

Organizational discourse analysis - well done or too rare? A reply to our critics

In this article we respond to Bargiela-Chiappini, Iedema and Mumby.We notice that there is considerable agreement concerning the state of the art of organizational discourse analysis, while also discussing the disagreements. We expand on some of the ontological issues inherent in our argument, further discuss the character of reductionism in organizational discourse analysis, the trappings of a pr

The Regress of Pure Powers Revisited

The paper aims to elucidate in better detail than before the dispute about whether or not dispositional monism—the view that all basic properties are pure powers—entails a vicious infinite regress. Particular focus is on Alexander Bird’s and George Molnar’s attempts to show that the arguments professing to demonstrate a vicious regress are inconclusive because they presuppose what they aim to prov

Simple rings and degree maps

For an extension $A/B$ of neither necessarily associative nor necessarily unital rings, we investigate the connection between simplicity of $A$ with a property that we call $A$-simplicity of $B$. By this we mean that there is no non-trivial ideal $I$ of $B$ being $A$-invariant, that is satisfying $AI \subseteq IA$. We show that $A$-simplicity of $B$ is a necessary condition for simplicity of $A$ f

Stylised facts of financial time series and hidden Markov models in continuous time

Hidden Markov models are often applied in quantitative finance to capture the stylised facts of financial returns. They are usually discrete-time models and the number of states rarely exceeds two because of the quadratic increase in the number of parameters with the number of states. This paper presents an extension to continuous time where it is possible to increase the number of states with a l

Formation and expansion of a new organizational field in experimental science

This paper examines the formation and expansion of a new organizational field in experimental science: synchrotron radiation laboratories. These labs were once peripheral servants of some specialisms of solid-state physics, but over the 40 years studied they have grown into a worldwide generic resource for tens of thousands of users in a broad spectrum of disciplines. The paper uses insights prima

Studies of tropical fruit ripening using three different spectroscopic techniques.

ABSTRACT. We present a noninvasive method to study fruit ripening. The method is based on the combination of reflectance and fluorescence spectroscopies, as well as gas in scattering media absorption spectroscopy (GASMAS). Chlorophyll and oxygen are two of the most important constituents in the fruit ripening process. Reflectance and fluorescence spectroscopies were used to quantify the changes of

Porous titanium granules are better than autograft bone as a bone void filler in lateral tibial plateau fractures: A randomised trial.

A total of 20 patients with a depressed fracture of the lateral tibial plateau (Schatzker II or III) who would undergo open reduction and internal fixation were randomised to have the metaphyseal void in the bone filled with either porous titanium granules or autograft bone. Radiographs were undertaken within one week, after six weeks, three months, six months, and after 12 months. The primary out

The French language is less and less used as an international scientific language and many French researchers publish their work in English. Nowadays, Annales de Chirurgie Plastique Esthétique is the only international plastic surgical journal published completely in French. The use of English loan words in French plastic surgery has never been studied.

Surfactant Behavior of Sodium Dodecylsulfate in Deep Eutectic Solvent Choline Chloride/Urea.

Deep eutectic solvents (DES) resemble ionic liquids but are formed from an ionic mixture instead of being a single ionic compound. Here we present some results that demonstrate that surfactant sodium dodecyl sulfate (SDS) remains surface-active and shows self-assembly phenomena in the most commonly studied DES, choline chloride/urea. X-ray reflectivity (XRR) and small angle neutron scattering (SAN

Pressure dependent isotopic fractionation in the photolysis of formaldehyde-d(2)

The isotope effects in formaldehyde photolysis are the key link between the delta D of methane emissions and the delta D of atmospheric in situ hydrogen production. A few recent studies have suggested that a pressure dependence in the isotopic fractionation can partly explain enrichment of deuterium with altitude in the atmosphere. The mechanism and the extent of this pressure dependency is, howev

Protein conformational exchange measured by (1)H R 1ρ relaxation dispersion of methyl groups.

Activated dynamics plays a central role in protein function, where transitions between distinct conformations often underlie the switching between active and inactive states. The characteristic time scales of these transitions typically fall in the microsecond to millisecond range, which is amenable to investigations by NMR relaxation dispersion experiments. Processes at the faster end of this ran

Comorbidities and Mortality in Bipolar Disorder A Swedish National Cohort Study

IMPORTANCE Bipolar disorder is associated with premature mortality, but the specific causes and underlying pathways are unclear. OBJECTIVE To examine the physical health effects of bipolar disorder using outpatient and inpatient data for a national population. DESIGN, SETTING, AND PARTICIPANTS National cohort study of 6 587 036 Swedish adults, including 6618 with bipolar disorder. MAIN OUTCOMES AN

Geospatial tools address emerging issues in spatial ecology: a review and commentary on the Special Issue

Spatial ecology focuses on the role of space and time in ecological processes and events from a local to a global scale and is particularly relevant in developing environmental policy and (mandated) monitoring goals. In other words, spatial ecology is where geography and ecology intersect, and high-quality geospatial data and analysis tools are required to address emerging issues in spatial ecolog
