Real-time PCR is fast, sensitive, specific, and can deliver quantitative data; however, two disadvantages are that this technology is sensitive to inhibition by food and that it does not distinguish between DNA originating from viable, viable nonculturable (VNC), and dead cells. For this reason, real-time PCR has been combined with a novel discontinuous buoyant density gradient method, called flot
Purpose To explore the effect of high-dose ifosfamide in first-line treatment for patients <= 40 years of age with nonmetastatic osteosarcoma of the extremity. Patients and Methods From March 1997 to September 2000, 182 patients were evaluated. Primary treatment consisted of two blocks of high-dose ifosfamide (15 g/m(2)), methotrexate (12 g/m(2)), cisplatin (120 mg/m(2)), and doxorubicin (75 mg/m(
The citations of highly cited papers in the life sciences published in 1986 and 2000 was examined to determine the extent to which early impact predicts long term impact. Linear correlation between early and post-peak impact was found to be about 0.7
This study compares the time required to activate a grasp or function of a hand prosthesis when using an electromyogram (EMG) based control scheme and when using a control scheme combining EMG and control signals from an inductive tongue control system (ITCS). Using a cross-over study design, 10 able-bodied subjects used a computer model of a hand and completed simulated grasping exercises. The ti
Background Transcatheter aortic valve replacement (TAVR) has become an established therapeutic option for patients with symptomatic, severe aortic valve stenosis (AS) who are ineligible or at high risk for conventional valvular surgery. In Northwestern Europe, the TAVR technology is also increasingly used to treat patients with an intermediate risk profile. Methods and results The study was design
A search for a charged Higgs boson (H+) in t (t) over bar decays is presented, where one of the top quarks decays via t -> H(+)b, followed by H+ -> two jets (c (s) over bar). The other top quark decays to Wb, where the W boson then decays into a lepton (e/mu) and a neutrino. The data were recorded in pp collisions at root s = 7 TeV by the ATLAS detector at the LHC in 2011, and correspond to an int
Metal nanostructures can transfer electromagnetic energy from femtosecond laser pulses to the near-field down to spatial scales well below the optical diffraction limit. By combining few-femtosecond laser pulses with photoemission electron microscopy, we study the dynamics of the induced few-cycle near-field in individual bowtie nanoantennas. We investigate how the dynamics depend on antenna size
This Letter presents the results of a search for a heavy particle decaying into an e(+/-)mu(+/-), e(+/-)tau(+/-), or mu(+/-)tau(+/-) final state in pp collisions at root s = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb(-1). No significant excess above the Standard Model expectation is observed, and exclusions at 9
A search for new charged massive gauge bosons, called W', is performed with the ATLAS detector at the LHC, in proton-proton collisions at a centre-of-mass energy of root s = 8 TeV, using a dataset corresponding to an integrated luminosity of 20.3 fb(-1). This analysis searches for W' bosons in the W' -> t (b) over tilde decay channel in final states with electrons or muons, using a multivariate me
BACKGROUND: Gastrectomy (Gx) causes osteopenia. The hypothesis tested in the present study is that Gx affects Ca homeostasis and that an impaired ability to handle Ca contributes to the Gx-evoked osteopenia. METHODS: SHAM-operated and Gx rats were compared with respect to changes in blood Ca2+ after oral or intravenous loads of CaCl2 1-2 weeks or 2-4 months after the operations. RESULTS: Different
The equilibrium self-diffusion of water contained within the porous structure of three different types of starch, viz. corn, wheat and potato starch was investigated. The samples were exposed to humid air until they reached a certain water content, the value of which was determined from the 1H NMR free induction decays. The water self-diffusion coefficient was determined by means of a p
In this study healthy never-smoking subjects (n = 18) were recruited from a population study. Bronchoalveolar lavage (BAL), blood lymphocytes and bronchial biopsies, analysed both in the epithelium and lamina propria, were stained for T and B lymphocytes, natural killer (NK) cells and different subpopulations of T lymphocytes. In BAL, significantly higher proportions of T lymphocytes (CD3), T lymp
The pine sawfly, Diprion jingyuanensis Xiao et Zhang, is a serious pest of Chinese pine (Pinus tabulaeformis Carr.) in the northern parts of China. The general biology of this recently described sawfly species is little known and in the present study we used a synthetic pheromone to monitor its flight period and to evaluate the possibility to use pheromone traps as a tool for estimating and predic
This thesis includes two different parts: One focusing on how to induce human embryonic stem cells (hESCs) to differentiate into insulin producing cells by following the normal pancreatic development pathway. These cells have then the potential to be an unlimited source for diabetes regenerative medicine. The second part of the thesis deals with how embryonic stem cells rid themselves of damaged p
Exposure to methylene chloride produced a time and concentration related increase in liver weight. The effect was more prominent in female mice than in male. The activity of plasma butyrylcholinesterase (BuChE) increased even more than the liver weight at corresponding exposures, but only in the males. Fatty infiltration was noticeable after exposure to 75 p.p.m. and was more prominent in the fema
Background: Patients with colorectal cancer were examined to determine (1) whether elevated carcinoembryonic antigen (CEA) levels, either before treatment or after surgery, was associated with an increased risk of overall or colorectal cancer-specific mortality or recurrence, and (2) whether high intensity follow-up would benefit those patients. Materials and methods: Post-hoc analysis based on 25
After the fall of Communism, the Serbian Orthodox Church has experienced a significant revival, part of which has been the recollection of past events, personas, sites and shrines in order to re-establish its position in the post-Yugoslav republics. One of these processes of recollection is devoted to the cult of St. Jovan Vladimir (d.1016) and the sites associated with him in southern Montenegro.
Background: Continuously high rates of overdose deaths in Sweden led to the decision by the Skåne County to initiate the first regional take-home naloxone program in Sweden. The project aims to study the effect of overdose prevention education and naloxone distribution on overdose mortality in Skåne County. Secondary outcome measures include non-fatal overdoses and overdose-related harm in the gen
