The Role of Hepatic Leukemia Factor in Hematopoiesis

The development of therapeutic methods based on stem cells (e.g. cell therapy, activating regeneration and organ transplantation), known as regenerative medicine, is still a novel area in the field of life sciences. If successful, such therapies could be applicable to many diseases currently lacking effective treatments, such as Parkinson’s disease, diabetes, heart disease or cancer.Stem cells are

Temperature and pH Controlled Self-Assembly of a Protein-Polymer Biohybrid

A novel pH and temperature dual-responsive bioconjugate is prepared by grafting thermoresponsive polymer chains from a pH-responsive protein amelogenin via atom transfer radical polymerization. To the best of our knowledge, this is the first time that amelogenin is exploited to prepare a hybrid biomaterial with new stimuli-responsive property. In both basic and acidic solutions the protein-polymer

Nanoparticle effect on neutrophil produced myeloperoxidase

Nanoparticles affect the immune system as they may interact directly with immune cells and activate them. However, it is possible that nanoparticles also interact with released cytokines and immunologically active enzymes. To test this hypothesis, the activity of myeloperoxidase released from activated neutrophils was measured in the presence of nanoparticles with different chemistry and size. In

A prospective observational treatment study of aerococcal urinary tract infection

Objectives: Aerococcus urinae and Aerococcus sanguinicola cause urinary tract infections (UTIs) and antibiotic treatment recommendations are solely based on in vitro findings and limited clinical experience. Our objective was to investigate the effectiveness of different treatment strategies in aerococcal UTI through a prospective observational study. Methods: Urine samples with aerococci were ide

Body size and risk of atrial fibrillation : A cohort study of 1.1 million young men

Background: Whilst tall stature has been related to lower risk of vascular disease, it has been proposed as a risk factor for atrial fibrillation. Little is known about other anthropometric measures and their joint effects on risk of atrial fibrillation. Objectives: We aim to investigate associations and potential joint effects of height, weight, body surface area (BSA) and body mass index (BMI) w

A 2-year follow-up study of patients with pharyngotonsillitis

Background: Longtime follow-up studies on patients with pharyngotonsillitis are rare. We aimed to describe the patterns of new visits for a sore throat, complications and tonsillectomy during 2 years in a cohort of patients with pharyngotonsillitis and non-infected controls. Methods: A retrospective chart review was performed on a cohort of patients with acute sore throat (n = 207), and non-infect

Demonized, domesticated, virtualized : fortification buildings as a case of Prussian heritage in present-day Kaliningrad

The article explores ways in which the nineteenth-century Prussian military architecture has been used and promoted as a part of the local heritage in the Russian exclave of Kaliningrad. Accommodation of the old fortification buildings to tourism and museum work has been publicly discussed since the beginning of the 2000s, but neither local nor federal authorities have proposed a plan to adapt the

An autonomous robot inspired by insect neurophysiology pursues moving features in natural environments

Objective. Many computer vision and robotic applications require the implementation of robust and efficient target-tracking algorithms on a moving platform. However, deployment of a real-time system is challenging, even with the computational power of modern hardware. Lightweight and low-powered flying insects, such as dragonflies, track prey or conspecifics within cluttered natural environments,

Psychosocial work dimensions, exposure to violence, and burnout in relation to attitudes towards the use of force among Swedish patrolling police officers

Introduction: Police work involves stressors specific to police workand to general organizational aspects of work. Some of the latterhas previously been identified as risk factors for burnout, particularly to increased degree of the burnout sub-dimension cynicism.Cynicism has in turn been related to a positive attitude to the use offorce to solve problems. In the present study the relationshipsbet

The benevolent ruler: The characterization of Jesus in Matt 11:25–30

The saying of Jesus in Matt 11:25–30 is often understood as a presentation of him as Wisdom personified or as wisdom teacher and great Revealer, influenced by the wisdom sayings in Sirach. The yoke of Jesus refers to his teaching/law, so the conclusion is that the teaching of Jesus is easy to perform or follow. Though the teaching role of Jesus is prominent in Matthew and his wisdom is underlined,

Habitat heterogeneity induces rapid changes in the feeding behaviour of generalist arthropod predators

The "habitat heterogeneity hypothesis" predicts positive effects of structural complexity on species coexistence. Increasing habitat heterogeneity can change the diversity (number of species, abundances) and the functional roles of communities. The latter, however, is not well understood as species and individuals may respond very differently and dynamically to a changing environment. Here, we exp

Prostate Cancer Death After Radiotherapy or Radical Prostatectomy : A Nationwide Population-based Observational Study

Background: There are no conclusive results from randomized trials on radiotherapy (RT) versus radical prostatectomy (RP) for prostate cancer. Numerous observational studies have suggested that RP is associated with a lower risk of prostate cancer death, but whether results have been biased due to limited adjustments for confounding factors is unknown. Objective: To compare the risk of prostate ca
