The main objective was to study the effect on progression-free survival (PFS) of adding erlotinib to bevacizumab as maintenance treatment following chemotherapy and bevacizumab as first-line treatment of metastatic colorectal cancer (mCRC).
The aim of this retrospective population-based study was to determine if there is any significant difference in academic achievement between students with a Pierre Robin Sequence (PRS) compared with the general population of Swedish students at the typical time of graduation from compulsory school (usually at 16 years of age). The data were obtained from the Swedish Medical Birth Register for the
Methods: The study population of healthy adult volunteers was divided into a sample for development of a prediction model (n = 63) and a testing sample (n = 30). Magnetic resonance imaging data were used to assess anatomical characteristics of the left ventricle: the angle between papillary muscles (PMA), the length of the left ventricle (LVL) and left ventricular mass (LVM). Twelve-lead electroca
Life cycle assessment (LCA) is increasingly used in waste management to identify strategies that prevent or minimise negative impacts on ecosystems, human health or natural resources. However, the quality of the provided support to decision- and policy-makers is strongly dependent on a proper conduct of the LCA. How has LCA been applied until now? Are there any inconsistencies in the past practice
To evaluate the gluten-free diet (GFD) adherenceafter one year of follow-up in children with screening-detected celiac disease (CD) in a general population.
Objective: To propose and evaluate a new method for assessing the potential impact on speech intelligibility when wearing a hearing protection device (HPD) in a noisy environment. Design: The method is based on a self adaptive method for finding the speech reception threshold (SRT) using speech material from the Callsign acquisition test (CAT) presented at a constant level while adjusting the leve
Improved outcome after rectal cancer surgery requires identification of novel risk factors of tumour recurrence in order to personalise therapy, that is, enhanced selection of high-risk patients to additional radiochemotherapy or intensified follow-up. In several tumour types, including colorectal cancer, high expression of the membrane-cytoskeleton linker ezrin has been suggested to impair progno
Large eddy simulation of diesel spray in a constant volume vessel as well as in an internal combustion engine has been performed. Spray is modeled using Eulerian-Lagrangian approach. The modeling involves primary and secondary break-up, the spray-induced turbulence (SIT) and the stochastic turbulence dispersion (STD) of parcels. Including SIT, based on Baharawaj et al. (2009), in coarse grids, e.g
We propose a novel interconnector design, termed bi-layer interconnector, for solid oxide fuel cells (SOFCs). It can disturb the fuel gas and air on the planes normal to the SOFC three-phase-boundary (TPB) layer. In this paper, a two-dimensional half-cell model is developed to study the concentration overpotentials in the fuel side of the SOFC stack with conventional and novel bi-layer interconnec
We consider a popular model for long-duration gamma-ray bursts, in which the progenitor star, a stripped helium core, is spun up by tidal interactions with a black hole companion in a compact binary. We perform population synthesis calculations to produce a representative sample of such binaries, and model the effect that the companion has on material that falls back on to the newly formed black h
Introduction. Both short and long sleep duration may increase risk of type 2 diabetes (diabetes). We studied if short and long sleep durations were associated with insulin resistance (IR) and insulin secretion in individuals without diabetes, and if the associations remained after we excluded individuals who reported more frequent and severe complaints of sleep apnea and insomnia. Participants and
Although small round gold nanoparticles (Au NPs) possess only a small degree of shape anisotropy, they support localized surface plasmon resonances and exhibit intrinsic optical anisotropy. These inherent features promote depolarized light scattering, whose temporal fluctuations carry information about rotational Brownian dynamics, and thus can be used to describe the size distribution of round Au
Phosphodiesterase (PDE) isoenzymes have been shown to play a role in the control of human male genital tissues. There are hints from basic research and clinical studies that PDE5 inhibitors may have the ability to retard the male ejaculatory response. While the expression of PDE isoenzymes in the human seminal vesicles (SVs) has been described, the distribution of cyclic adenosine monophosphate (A
An online survey in the form of a questionnaire was conducted to obtain the opinion of computer users with tetraplegia on their current computer interfaces and to assess desirable applications for future independent control using assistive devices. The survey included questions related to information about the respondents' injury/disease, everyday activities and social life, electronic devices and
In STEMI, grade-3 ischemia (G3) on admission ECG predicts larger infarct size (IS) than grade-2 (G2). We evaluated whether pre-hospital G3 and its temporal behavior are associated with IS and salvage after pPCI.
Gelatin-based cryogels were prepared by using a novel crosslinker, oxidized dextran, which was synthesized and used in the study. The cryogels were also loaded with freshly formed hydroxyapatite (HA) particles. These cryogels are opaque, spongy and highly elastic and have a pore structure with large interconnected pores. They swell about 500% in aqueous media and within a few minutes reach their f
The activated forms of the complement lectin pathway (LP) proteases MASP-1 and -2 are able to cleave the coagulation factors prothrombin, fibrinogen, factor XIII and TAFI in vitro. In vivo studies also show that MASP-1 is involved in thrombogenesis, OBJECTIVES: To clarify the not yet identified mechanisms involved in triggering activation of the LP during thrombotic reactions.
A neural model with N interacting neurons is considered. A firing of neuron i delays the firing times of all other neurons by the same random variable theta((i)), and in isolation the firings of the neuron occur according to a renewal process with generic interarrival time Y-(i). The stationary distribution of the N-vector of inhibitions at a firing time is computed, and involves waiting distribut
BACKGROUND: Folate is involved in DNA synthesis and methylation and may thereby influence carcinogenesis. OBJECTIVES: We examined plasma folate (P-folate) concentration in relation to genotypes of the folate-metabolizing enzyme methylenetetrahydrofolate reductase [MTHFR 677C<--T (rs1801133) and 1298A<--C (rs1801131)]. We also explored whether P-folate was associated with risk of postmenopausal bre
