WUSCHEL protein movement mediates stem cell homeostasis in the Arabidopsis shoot apex

WUSCHEL (WUS) is a homeodomain transcription factor produced in cells of the niche/organizing center (OC) of shoot apical meristems. WUS specifies stem cell fate and also restricts its own levels by activating a negative regulator, CLAVATA3 (CLV3), in adjacent cells of the central zone (CZ). Here we show that the WUS protein, after being synthesized in cells of the OC, migrates into the CZ, where

Co-morbidity and mortality in Swedish patients with haemophilia - A register study

Haemophilia is an X-linked inherited recessive disorder affecting males. The increased risk of hemorrhage is explained by the deficiency in either coagulation factor VIII (haemophilia A) or IX (haemophilia B). The severity of haemophilia A and B is characterized by the bleeding pattern. For severe haemophilia bleeding is often spontaneous, mainly in muscles and joints. Since the 1950s the manifest

Head to head comparisons of two modalities of perfusion adenosine stress echocardiography with simultaneous SPECT

Background: Real-time perfusion (RTP) contrast echocardiography can be used during adenosine stress echocardiography (ASE) to evaluate myocardial ischemia. We compared two different types of RTP power modulation techniques, angiomode (AM) and high-resolution grayscale (HR), with Tc-99m-tetrofosmin single-photon emission computed tomography (SPECT) for the detection of myocardial ischemia. Methods:

Organizational inscriptions of network pictures: A meso-level analysis

This paper deals with organizational inscriptions of managerial cognitions elaborating on the emerging concept of network pictures. While previous studies on network pictures have concentrated on individual managers' cognitive views of business networks, this study operates on a focal company level (meso-level) and is concerned with how managerial cognitions are manifested in organizational artifa

On the interaction between imperfect compliance and technology adoption: taxes versus tradable emissions permits

This paper analyzes the effects of the interaction between technology adoption and incomplete enforcement on the extent of violations and the rate of abatement technology adoption. We focus on price-based and quantity-based emission regulations. First, we show that in contrast to uniform taxes, under tradable emissions permits (TEPs), the fall in permit price produced by technology adoption reduce

Forecasting monthly precipitation in Central Chile: a self-organizing map approach using filtered sea surface temperature

Western South America is subject to considerable inter-annual variability due to El Nio-Southern Oscillation (ENSO) so forecasting inter-annual variations associated with ENSO would provide an opportunity to tailor management decisions more appropriately to the season. On one hand, the self-organizing maps (SOM) method is a suitable technique to explore the association between sea surface temperat

Trygg, sviken eller osäker : Tankar och förberedelser inför pensioneringen

This dissertation aims to investigate and analyze people's preparation for retirement. The study has been made through semi-structured interviews with 78 people born between the years 1931-1981 regarding their preparations for retirement. The analysis is based on the model Reflexive Planning for Later Life, coping, bounded rationality, behavioural finance and the concept of governmentality, and

Males are sensitive - sex-dependent effect of rearing conditions on nestling growth

The sex-dependent effect of environmental conditions on nestlings has been extensively studied in size dimorphic birds. Whether males or females are more sensitive to poor conditions is not yet clear; however, the degree of sexual size-dimorphism, brood size and their interactions seem to influence the pattern. Much less is known about sex-dependent environmental sensitivity in size-monomorphic sp

Broad spectrum moderators and advanced reflector filters using (208)pb

Cold and thermal neutrons used in neutrons scattering experiments are produced in nuclear reactors and spallation sources. The neutrons are cooled to thermal or cold temperatures in thermal and cold moderators, respectively. The present study shows that it is possible to exploit the poor thermalizing property of Pb-208 to design a broad spectrum moderator, i.e. a moderator which emits thermal and

Respiratory Tract Infections: Aspects of Aetiology, Virulence, and Communicable Disease Control

Popular Abstract in Swedish Barn ar ofta bärare av luftvägsbakterien pneumokocker i de övre luftvägarna och det är barnen som anses vara den största reservoaren för bakterien i vårt samhälle. Vanliga pneumokockinfektioner såsom öron-, bihåle- eller lunginflammation föregås av att man bär på bakterien. De flesta barn som är bärare blir dock inte sjuka. Vuxna är mer sällan bärare av bakterien. PneuThe paediatric nasopharyngeal flora is regarded as the largest reservoir for Streptococcus pneumoniae, and the carrier state is always antecedent to infection and a prerequisite for dispersion of these bacteria. Pneumococci are the predominant aetiology of bacterial respiratory tract infections and a major cause of morbidity and mortality, in the most severe cases due to invasive pneumococcal dise

Myocardial Topical Negative Pressure

The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. When used in wound therapy, topical negative pressure has been shown to increase microvascular blood flow, to stimulate granulation tissue formati

Ungdomars övergång från skola till arbetsliv - aktuella utmaningar och lokala erfarenheter

I denna forskningsrapport presenteras studier som berör ungdomars arbetsmarknadsetablering. Stor uppmärksamhet ägnas offentliga regelverk och insatser som görs för att underlätta för unga individer att fullborda en gymnasieutbildning respektive att ta steget från skola till arbetsliv. Den nationella problembilden speglas och fördjupas via erfarenheter från tio olika kommuner. Sammantaget visar u

Massive MIMO for Next Generation Wireless Systems

Multi-user MIMO offers big advantages over conventional point-to-point MIMO: it works with cheap single-antenna terminals, a rich scattering environment is not required, and resource allocation is simplified because every active terminal utilizes all of the time-frequency bins. However, multi-user MIMO, as originally envisioned, with roughly equal numbers of service antennas and terminals and freq

Use of bacteria- and fungus-binding mesh in negative pressure wound therapy provides significant granulation tissue without tissue ingrowth.

Objective: Bacteria- and fungus-binding mesh traps and inactivates bacteria and fungus, which makes it interesting, alternative, and wound filler for negative pressure wound therapy (NPWT). The aim of this study was to compare pathogen-binding mesh, black foam, and gauze in NPWT with regard to granulation tissue formation and ingrowth of wound bed tissue in the wound filler. Methods: Wounds on the
