We report on the measurement of the inclusive Upsilon(1S) production in Pb-Pb collisions at root s(NN) = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its mu(+)mu(-) decay channel with the ALICE detector at the Large Hadron Collider. Astrong suppression of the inclusive Upsilon(1S) yield is observed with respect to pp collisions scaled by the num

Asylum seekers often find themselves in a situation where the structure and content of daily occupations have been disrupted and they might have limited access to paid work and education. Studies have shown that asylum seekers experience occupational depri- vation and a change in daily occupations which might even influence their identity. Such deprivation can eventually lead to dissatisfaction wi

Objective. Enterohepatic Helicobacter species (EHS) have previously been found in adults with hepatobiliary diseases. Here, we report the prevalence of Helicobacter pylori and EHS in liver and gastric tissue in children and adolescents with chronic liver disease (CLD). Material and methods. Seventy-seven consecutive children and adolescents with CLD with or without ulcerative colitis or Crohn's di

Popular Abstract in Swedish Neuroblastom är den vanligaste solida tumören, utanför hjärnan, hos små barn och finns nästan inte alls hos vuxna. Varje år insjuknar mellan femton och tjugo barn i Sverige, de flesta före två års ålder. Överlevnaden har ökat de senaste tjugo åren men är fortfarande på låga nivåer för de mer aggressiva formerna. Neuroblastom uppstår i det sympatiska nervsystemet. DärförIn this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. Our first focus was on one of the most important biological risk factors in neuroblastoma -- amplification of the oncogene MYCN in the tumour cells. Because amplified MYCN typical

Difference between sexes in parasitism is a common phenomenon among birds, which may be related to differences between males and females in their investment into immune functions or as a consequence of differential exposure to parasites. Because life-history strategies change sex specifically during the annual cycle, immunological responses of the host aiming to reduce the impact of parasites may

In this study, a novel method of preparation of cryogels based on oxidised dextran (Ox.D) and gelatin (Gel) without sodium borohydride is proposed. The physico-chemical properties of obtained hydrogels were investigated. It was found that the stability of cryogels Ox.D-Gel is significantly depended on pH, and mechanical properties were improved after the freeze drying. The schemes of the reactions

The elliptic, v(2), triangular, v(3), and quadrangular, v(4), azimuthal anisotropic flow coefficients are measured for unidentified charged particles, pions, and (anti-)protons in Pb-Pb collisions at root S-NN = 2.76 TeV with the ALICE detector at the Large Hadron Collider. Results obtained with the event plane and four-particle cumulant methods are reported for the pseudo-rapidity range vertical

Motor complications impair quality of life and cause severe disability in patients with advanced Parkinson's disease (PD). Since they are often refractory to medical therapy, interventional therapies have been developed, which can provide a considerable reduction of daily off-time and dopaminergic dyskinesias. Continuous dopaminergic drug delivery (CDD) is based on the steady stimulation of striat

BACKGROUND: Knee rotation plays an important part in knee kinematics during weight-bearing activities. An external device for measuring knee rotation (the Rottometer) has previously been evaluated for validity by simultaneous measurements of skeletal movements with Roentgen Stereometric Analysis (RSA). The aim of this study was to investigate the reliability of the device. METHOD: The within-day

In order to achieve ultra-low emissions of both NOX and CO it is imperative to move the blow out limit towards leaner equivalence ratios and by supplying heat and reactive species to the flame zone the lean stability limit can be lowered. Heat and reactive species can be supplied to the flame zone by use of a pre-chamber combustor. In this study a central body burner, called the RPL (Rich-Pilot-Le

The Swedish Board of Fire Research has initiated a pre-study to investigate the possibility to setup a larger research project that would deal with residential fires. Through interviews, literature studies and an initial statistical study, it is clear that there is a need for an umbrella project that focuses on residential fires. The major reason for doing this it that the costs of residential f

Sight-threatening diabetic retinopathy has been treated with photocoagulation for decades but the mechanisms behind the beneficial clinical effects are poorly understood. One target of irradiation and a potential player in this process is the retinal pigment epithelium (RPE). Here we establish an in vitro model for photocoagulation of human RPE cells.

Sexual selection may drive speciation, but most research focuses on pre-copulatory sexual selection, overlooking post-copulatory processes. Post-copulatory sexual selection in allopatric populations could drive divergence in post-copulatory pre-zygotic (PCPZ) phenotypes, limiting gene flow upon secondary contact. Here, we performed in vitro experiments examining one potential PCPZ barrier between

So far it is not known whether epidermal melanins are solely photoprotective or also phototoxic. Also largely unknown are underlying UV-induced mechanisms and impact of the chemical structure. This perspective will focus on the current insights into the UV-dissipative mechanisms in melanin model systems and the implications for the in vivo pigments. We will also identify future research perspectiv
