Immune functions of intestinal dendritic cells

The intestinal surface is daily challenged with tremendous amount of foreign material derived our diet and from the commensal bacteria that densely populate the mucosal surface. Occasionally the gut mucosa is exposed to pathogens trying to enter our body. The important task of the intestinal immune system is to remain tolerant toward innocuous luminal constituents and to elicit defense responses t

Hepatic Leukemia Factor Maintains Quiescence of Hematopoietic Stem Cells and Protects the Stem Cell Pool during Regeneration

The transcription factor hepatic leukemia factor (HLF) is strongly expressed in hematopoietic stem cells (HSCs) and is thought to influence both HSC self-renewal and leukemogenesis. However, the physiological role of HLF in hematopoiesis and HSC function is unclear. Here, we report that mice lacking Hlf are viable with essentially normal hematopoietic parameters, including an intact HSC pool durin

Theoretical study of the effect of π+-π+ association in imidazolium ionic liquids at charged interfaces

We develop an extended classical density-functional theory to describe clustering of imidazolium-based cations into linear chains, driven by π-π stacking. We find that the associating system displays a similar short-ranged structure to the completely dissociated fluid. We also construct a restricted primitive model for associating ionic species in an RTIL+solvent mixture. The double-layer formed i

Renormalization of effective interactions in a negative charge transfer insulator

We compute from first principles the effective interaction parameters appropriate for a low-energy description of the rare-earth nickelate LuNiO3 involving the partially occupied eg states only. The calculation uses the constrained random-phase approximation and reveals that the effective on-site Coulomb repulsion is strongly reduced by screening effects involving the oxygen-p and nickel-t2g state

Compact 200 kHz HHG source driven by a few-cycle OPCPA

We present a compact HHG source driven by a few-cycle, few μJ, 200 kHz OPCPA system. Efficient harmonics are generated from Neon, Argon and Krypton with conversion efficiency of 4.0×10-8, 1.2×10-6 and 4.1×10-6, respectively.

Lightweight Dispatcher Constructions for Control Flow Flattening

The objective of control flow obfuscation is to protect the program control flow from analysis. A technique called control flow flattening addresses static analysis by hiding edges between basic blocks in a program and introduces a dispatcher block that determines the execution order of the randomized blocks.In this paper we propose a novel flattening construction and lightweight dispatchers that The objective of control flow obfuscation is to protect the program control flow from analysis.

Defining Human Enhancement : Towards a Foundational Conceptual Tool for Enhancement Law

Emerging technologies open the prospect of extraordinary interventions on the human body. These may go beyond what is strictly necessary to sustain health and well-being. While responding to social and ethical challenges of such advances, the Law simultaneously faces the challenge of reflecting on the legitimacy to legislate and on whether the existing legal framework is appropriate to address the

Cutting Edges and Weaving Threads in the Gene Editing (Я)evolution : Reconciling scientific progress with Legal, Ethical, & Social concerns

Gene editing technologies, such as CRISPR/Cas9, hold great promises for the advancement of science and technology. These foundational technologies enable to modify the genetic structure of living organisms with unprecedented precision. Potential applications include both plant, animal and human genetic interventions. In plant biology, gene editing introduces more precise, target- and time-efficien

Rules and Tools in the Battle against Superbugs - A call for integrated strategies and enhanced international collaboration to promote antimicrobial drug development

The lack of treatments during the recent Ebola and Zika outbreaks dramatically exposed the vulnerability of the global health system and the dire consequences thereof. But even where therapies against infectious diseases had been available, an additional threat has gained world-wide attention: antimicrobial resistance (AMR). A growing number of microbial organisms are becoming resistant to availab

Patentability of human enhancement : From ethical dilemmas to legal (un)certainty

Emerging technologies are paving the way for future revolutionary advances in science that may open the possibility to change the very anthropological definition of human being. This mere possibility has lead to ethical interrogations concerning the nature and boundaries of human nature and our relationship with science and technology. Meanwhile the Law has faced the challenge of reflecting on the

EU Design Law and 3D Printing : Finding the Right Balance in a New E-Ecosystem

The article considers the implications for EU design law of 3D-printing. It first describes the 3D-printing technology and the e-ecosystem which is evolving around the technology and involves a number of new stakeholders who in different ways are engaged in the making and sharing of CAD-files and/or printing. It is submitted that it is only a matter of time before 3D-printing equipment becomes ubi

Patenting Nanomedicine in Europe : Applying the 'medical methods exception' to emerging technologies

Patenting Nanomedicine in Europe: Applying the ‘medical methods exception’ to emerging technologies is based on the authors PhD dissertation, defended in March 2014, at the University of Copenhagen. The book debates restrictions on the patentability of medical methods in European Patent Law. The main question addressed is whether it is viable and advisable the reinterpretation, reformulation or re

A “ray of hope” for European stem cell patents or “out of the smog into the fog”?

In Case C-364/13 International Stem Cell Corporation (ISCC) v. Comptroller General of Patents (December 18th, 2014), the Court of Justice of the European Union (CJEU) distinguished its’ earlier ruling in Brüstle v. Greenpeace (Brüstle) with regard to non-fertilized human ova stimulated by parthenogenesis. The Court found that in order to be considered a ‘human embryo’- and thus to be unpatentable

Legal method and lnterpretation in International IP law : Pluralism or Systemic Coherence

While pluralism and minimum harmonisation may have advantages concerning substantive requirements for IP protection there is an argument to be made in favour of establishing further harmonisation concerning rules and principles for legal interpretation of international or regional IP treaties, conventions and other legal instruments. Increasing autonomy of IP Law as a legal discipline and the deve
