Evacuation elevators in an underground metro station : A Virtual Reality evacuation experiment

The number of underground metro stations around the world is steadily increasing and deep stations are becoming more common. Evacuation elevators can be a way to mitigate many of the evacuation problems of deep stations, e.g., fatigue. However, the elevators need to be used by evacuees to be effective. In order to study the influence of evacuation measures on elevator usage, experiments were perfo

In recent years, parenting support has gained traction in the Swedish welfare state in both policy and practice. Parenting is seen as determining child outcomes and are thus in need of knowledge and expertise. Yet, at the same time, parents are conceptualised as experts of their own child. The intriguing paradox between parents being experts while at the same time being in need of parenting suppor

A critical analysis of organizational transformation – PSR

Purpose: Hunter Harrison, CEO of the railroad company CSX, died on December 16, 2017. Harrison, known as the railroad transformation guru, was a controversial person. While his transformations were applauded by investors, they were also subject to significant criticism. The author changes triggered service disruptions, customer complaints and federal scrutiny. The purpose of this paper is to condu

Intestinal Delivery of Proinsulin and IL-10 via Lactococcus lactis Combined With Low-Dose Anti-CD3 Restores Tolerance Outside the Window of Acute Type 1 Diabetes Diagnosis

A combination treatment (CT) of proinsulin and IL-10 orally delivered via genetically modified Lactococcus lactis bacteria combined with low-dose anti-CD3 (aCD3) therapy successfully restores glucose homeostasis in newly diagnosed non-obese diabetic (NOD) mice. Tolerance is accompanied by the accumulation of Foxp3+ regulatory T cells (Tregs) in the pancreas. To test the potential of this therapy o

Host transcriptional responses to high-and low-virulent avian malaria parasites

The transcriptional response of hosts to genetically similar pathogens can vary substantially, with important implications for disease severity and host fitness. A low pathogen load can theoretically elicit both high and low host responses, as the outcome depends on both the effectiveness of the host at suppressing the pathogen and the ability of the pathogen to evade the immune system. Here, we i

Trapped fourth ventricle : a rare complication in children after supratentorial CSF shunting

Purpose: Trapped fourth ventricle (TFV) is a well-identified problem in hydrocephalic children. Patients with post-hemorrhagic hydrocephalus (PHH) are mostly affected. We tried to find out predisposing factors and describe clinical findings to early diagnose TFV and manage it. Methods: We reviewed our database from 1991 to 2018 and included all patients with TFV who required surgery. We analyzed p

Odling av sällsynta växter i kulturmiljöer

Många växt- och djurarter har missgynnats av landskapsförändringar och riskerar att försvinna om de inte får hjälp. Länsstyrelsen upprättade därför 2017 en lista med förslag på kommunala ansvarsarter i Skåne. Varje kommun har tilldelats några hotade arter som har sin utbredningsmässiga tyngdpunkt i kommunen.

The responses of moss-associated nitrogen fixation and belowground microbial community to chronic Mo and P supplements in subarctic dry heaths

Aims: Although nitrogen (N) fixation by moss-associated bacteria is the main source of new N in N-limited ecosystems like arctic tundra, we do not know which nutrient, molybdenum (Mo) or phosphorus (P), is rate-limiting for sustaining this process in the long-term. Further, how moss-associated N2 fixation impacts the belowground microbial regulation of decomposition remains unresolved. Methods: Mo

The paper takes up a well-known constitutional subject concerning the limitations of private bills by reformulating the problem in system theoretical terms. This move allows for examining how the law as a social system carries through the task of establishing distinctions between legal/illegal in a situation where there is no precedence in the form of prior court decisions. After a short introduct

Patient-reported visual function outcome in cataract surgery : test–retest reliability of the Catquest-9SF questionnaire

Purpose: To study the test–retest reliability of the Catquest-9SF questionnaire in cataract surgery. Methods: A single-centre prospective non-randomized test–retest study was conducted using the Swedish National Cataract Register and the Catquest-9SF questionnaire, which is a valid patient-reported outcome measurement tool developed and used for evaluating quality and visual disability outcome in

Systematics and evolution of the African butterfly genus Mylothris (Lepidoptera, Pieridae)

We study the systematics and evolutionary history of the Afrotropical butterfly genus Mylothris (Lepidoptera: Pieridae) based on six gene regions (COI, EF1a, GAPDH, MDH, RpS5 and wingless). We find that the genus can be placed into five species groups, termed the jacksoni, elodina, rhodope, agathina and hilara groups. Within these species groups, we find that many species show very little genetic

Bladder cancer therapy without toxicity—A dose-escalation study of alpha1-oleate

Potent chemotherapeutic agents are required to counteract the aggressive behavior of cancer cells and patients often experience severe side effects, due to tissue toxicity. Our study addresses if a better balance between efficacy and toxicity can be attained using the tumoricidal complex alpha1-oleate, formed by a synthetic, alpha-helical peptide comprising the N-terminal 39 amino acids of alpha-l

The PNPLA3-I148M variant increases polyunsaturated triglycerides in human adipose tissue

Background & Aims: The I148M variant in PNPLA3 is the major genetic risk factor for non-alcoholic fatty liver disease (NAFLD). The liver is enriched with polyunsaturated triglycerides (PUFA-TGs) in PNPLA3-I148M carriers. Gene expression data indicate that PNPLA3 is liver-specific in humans, but whether it functions in adipose tissue (AT) is unknown. We investigated whether PNPLA3-I148M modifie

Phosphorus addition increased carbon partitioning to autotrophic respiration but not to biomass production in an experiment with Zea mays

Plant carbon (C) partitioning—the relative use of photosynthates for biomass production, respiration, and other plant functions—is a key but poorly understood ecosystem process. In an experiment with Zea mays, with or without arbuscular mycorrhizal fungi (AMF), we investigated the effect of phosphorus (P) fertilization and AMF on plant C partitioning. Based on earlier studies, we expected C partit

High risk of non-alcoholic liver disease mortality in patients with chronic hepatitis C with illicit substance use disorder

Aims: Hepatitis C virus (HCV) is a slowly progressive disease, often transmitted among people who inject drugs (PWID). Mortality in PWID is high, with an overrepresentation of drug-related causes. This study investigated the risk of death in patients with chronic hepatitis C virus (HCV) infection with or without illicit substance use disorder (ISUD). Methods: Patients with HCV were identified usin

Dwarfism in close continental amphibian populations despite lack of genetic isolation

Ample variation in body size is common in vertebrates over extensive geographical distances, or in isolated populations, where effective geographical barriers may cause dwarfism or gigantism. Here we study potential causes of extreme size reduction in continental populations of amphibians within a short geographical distance and in the absence of geographical barriers.

Quality of life with pharmacological treatment in patients with benign prostatic enlargement : results from the Evolution European Prospective Multicenter Multi-National Registry Study

Background: Lower urinary tract symptoms due to benign prostate enlargement (LUTS/BPE) can lead to significant disturbances to health-related quality of life (HRQoL) and psychological well-being. The aim of this study was to evaluate the effect of pharmacological treatment of LUTS/BPE on disease specific and generic QOL measures. Methods: Evolution was a European prospective, multicenter multi-nat

Procrastination, Affective State, Rumination, and Sleep Quality : Investigating Reciprocal Effects with Ambulatory Assessment

Procrastination is a prevalent problem among university students and associated with high long-term costs, but the short-term antecedents and consequences of procrastination are not well understood. Some related negative outcomes could be consequences as well as predictors of procrastination. The aim of the present study was to investigate possible reciprocal associations of affective, cognitive a
