Lactobacillus reuteri Maintains a Functional Mucosal Barrier during DSS Treatment Despite Mucus Layer Dysfunction

Treatment with the probiotic bacterium Lactobacillus reuteri has been shown to prevent dextran sodium sulfate (DSS)-induced colitis in rats. This is partly due to reduced P-selectin-dependent leukocyte-and platelet-endothelial cell interactions, however, the mechanism behind this protective effect is still unknown. In the present study a combination of culture dependent and molecular based T-RFLP

Phenotypic plasticity in response to the social environment: effects of density and sex ratio on mating behaviour following ecotype divergence.

The ability to express phenotypically plastic responses to environmental cues might be adaptive in changing environments. We studied phenotypic plasticity in mating behaviour as a response to population density and adult sex ratio in a freshwater isopod (Asellus aquaticus). A. aquaticus has recently diverged into two distinct ecotypes, inhabiting different lake habitats (reed Phragmites australis

Two-stage anaerobic digestion of aerobic pre-treated sisal leaf decortications residues: hydrolases activities and biogas production profile

A two-stage system was investigated for anaerobic digestion (AD) of aerobically pre-treated sisal leaf decortication residue (SLDR) with regard to hydrolytic enzymes and biogas production. The system consisted of a solid-bed bioreactor for hydrolysis connected to methanogenic bioreactor packed with sisal fibre decortication residues (SFDR) as biofilm carriers. Some of the enzymes produced by micro

Measuring charm and bottom using the PHENIX silicon vertex detector

The PHENIX experiment at RHIC has embarked on a broad range of upgrades to enhance its physics reach. One of the upgrades consists of a set of silicon vertex trackers that combine to cover the pseudorapidity range − 2.4 to 2.4. A description of the vertex detectors and some of their physics goals and capabilities will be given, as well as technology choices and results from prototype components.

Outcomes of a Standardized Surgical and Rehabilitation Program in Transtibial Amputation for Peripheral Vascular Disease: A Prospective Cohort Study.

Johannesson A, Larsson G-U, Ramstrand N, Lauge-Pedersen H, Wagner P, Atroshi I: Outcomes of a standardized surgical and rehabilitation program in transtibial amputation for peripheral vascular disease: A prospective cohort study. OBJECTIVE:: To study the outcomes of a new surgical and rehabilitation program for initial unilateral transtibial amputation in patients with peripheral vascular disease.

Anisotropic density growth of bone-A computational micro-sphere approach

Bones are able to adapt their local density when exposed to mechanical loading. Such growth processes result in densification of the bone in regions of high loading levels and in resorption of the material in regions of low loading levels. This evolution and optimisation process generates heterogeneous distributions of bone density accompanied by pronounced anisotropic mechanical properties. While

Quantitative Analysis of Influences of Model Plant Mismatch on Control Loop Behavior

There is normally a mismatch between the current model of the plant and the model that was used for design. This mismatch is normally acceptable when the controller is designed. But if the process dynamics changes, the mismatch may be so large that the control behavior degrades and may be unacceptable. This paper evaluates the influences of model plant mismatch on the control loop behavior quantit

Imaging in gynecological disease (10): clinical and ultrasound characteristics of decidualized endometriomas surgically removed during pregnancy

Objectives To describe the clinical history and ultrasound findings in women with decidualized endometriomas surgically removed during pregnancy. Methods In this retrospective study, women with a histological diagnosis of decidualized endometrioma during pregnancy who had undergone preoperative ultrasound examination were identified from the databases of seven ultrasound centers. The ultrasound ap

Organizational Image, Identification, and Cynical Distance: Prestigous Professionals in a Low-Prestige Organization

This study examines how a negative organizational image influences organizational identification among prestigious professionals working in a lowprestige organization. A communicative perspective on identification is used to illustrate previously unexplored processes of cynical distancing and shifts in identification targets as ways for business professionals to cope with discrepancies between the

Body condition and head size in snakes

On several occasions during my many years of working with various snake species, I observed a significant positive relationship between body condition and head size (the former calculated from residual scores from a general linear regression of In-transformed mass on In-transformed snout-vent length). Based on results from my long-term study of water pythons (basis fuscus) this relationship is, ho

Lichens and Lichenicolous Fungi of Yosemite National Park, California

We compiled literature, intensively studied 15 sites as a group, and collected opportunistically in other areas of the Yosemite National Park. We report a total of 562 species of lichenized fungi from the Park, adding 461 species to the total of 101 species reported for the Park by the National Park Service database. An additional 22 lichenicolous fungi are reported here. Two nonlichenized fungi a

Door-stepping as a strategy for improved food waste recycling behaviour Evaluation of a full-scale experiment

Comparisons were made between two groups of households in a multi-family residential area in order to investigate how oral information through a door-stepping campaign can influence household food waste recycling behaviour from a quantitative as well as qualitative perspective. Source-separation behaviour was assessed both through weakly weighting of all source-separated food waste and dry recycla
