Although CD8+ T cell tolerance to tissue-specific antigen (TSA) is essential for host homeostasis, the mechanisms underlying peripheral cross-tolerance and whether they may differ between tissue sites remain to be fully elucidated. Here, we demonstrate that peripheral cross-tolerance to intestinal epithelial cell (IEC)–derived antigen involves the generation and suppressive function of FoxP3+CD8+

I discuss the dilution of responsibility of action and the idea of a symmetrical relationship between artefacts and humans. In doing so, I argue that meaning making is an activity unilaterally performed by agents, leading to an asymmetrical relationship between agents and artefacts. Therefore, the study of the one who is responsible for the action, the meaning-maker (with the capability to act) is

Background: Mohs micrographic surgery (MMS) is a precise, tissue-sparing surgical technique that offers superior cure rates compared to traditional surgical excision. However, the degree of difficulty of MMS depends on many variables, and consequently, the number of surgical stages required for each case is quite unpredictable.Objectives: To identify risk factors for complicated MMS, defined as MM

A frequency domain, weighted least squares, sensitivity function shaping procedure is presented. Pole placement is used as the basic servo design procedure. Controller overparametrization gives the degree of freedom for shaping the sensitivity function. A benchmark design example shows the capabilities of the method. The computation is simple making the design suitable for adaptive control.

Diet and ambient temperature affect animal physiology, survival and reproductive success. However, knowledge of how these environmental factors interact to shape physiological processes and life-history traits of birds and other animals is largely lacking. By exposing adult great tits (Parus major) to two contrasting diets (saturated or unsaturated fatty acids; SFAs and UFAs, respectively) and amb

Niche expansion is attained by adaptations in two generalized phenotypical traits - niche position and niche width. This gives room for a wide range of conceptual ways of niche filling. The niche variation hypothesis reduces the range by predicting that expansion occurs by increasing variation in niche position, which has been debated on empirical and theoretical grounds as also other options seem

Objectives: Several studies have shown mortality and suicide risk in substance use disorders, and autopsy findings with respect to the used substances. However, there seems to be a gap in the knowledge about substances misused in life and at death at the within-person level. Methods: All consecutive, autopsied patients during 1993 to 1997, who had been in contact with the Addiction Centre in Malmö

Insect genitalia are important for species identification and taxonomy and are key traits for the evolution of reproductive isolation through their 'lock-And-key mechanism'. Nevertheless, few studies have evaluated intraspecific variation and the impact of seasonal environmental variation on genital morphology. We used geometric morphometric analysis to quantify male genital morphology within and

In transposition of the great arteries (TGA), certain coronary patterns have been associated with major adverse events early after the arterial switch operation (ASO). We sought to determine the impact of preoperative echocardiographic (ECHO) diagnosis on the intra­ and postoperative morbidity. All patients with TGA born between June 2001 and June 2017 and who underwent ASO were reviewed. Data on

IMPORTANCE Intensive follow-up of patients after curative surgery for colorectal cancer is common in clinical practice, but evidence of a survival benefit is limited. OBJECTIVE To examine overall mortality, colorectal cancer–specific mortality, and colorectal cancer–specific recurrence rates among patients with stage II or III colorectal cancer who were randomized after curative surgery to 2 alter

Most land-living organisms regularly experience dehydration. In nature, one commonly applied strategy to protect against this osmotic stress is to introduce small polar molecules with low vapor pressure, commonly called osmolytes. Two examples of naturally occurring small polar compounds are urea and trimethylamine N-oxide (TMAO), which are known to have counteracting effects on protein stability.

This article presents the results of a study of the Swedish multi-family housing stock in relation to its daylight performance under overcast sky conditions. A total of 8573 rooms in 35 existing buildings were investigated using advanced lighting simulations to determine their point daylight factor, as defined in the current building regulations. The buildings were selected based on their architec

Fashion is a social phenomenon par excellence. A simple sociological definition of fashion is 'being first with the latest.' Its underlying principle is revealed in the link between the modus derivatives and the term 'modern,' with its original meaning of 'now' or 'for today.' Fashion revolves around imitation and diffusion, and it applies to all domains of social life, though most of the research

Background--Interleukin-23 (IL-23) has been implicated in inflammatory and autoimmune diseases by skewing CD4+ T helper cells towards a pathogenic Th17 phenotype. In this study we investigated the presence of IL-23 receptor (IL-23R)-expressing cells in the atherosclerotic aorta and evaluated the effect of IL-23R deficiency on atherosclerosis development in mice. Methods and Results--We used hetero
