Non-linear mixed effects modeling of antiretroviral drug response after administration of lopinavir, atazanavir and efavirenz containing regimens to treatment-naive HIV-1 infected patients

The objective of this analysis was to compare three methods of handling HIV-RNA data below the limit of quantification (LOQ) when describing the time-course of antiretroviral drug response using a drug-disease model. Treatment naive Scandinavian HIV-positive patients (n = 242) were randomized to one of three study arms. Two nucleoside reverse transcriptase inhibitors were administrated in combinat

Sociocultural Care, Service Context, and IADL Dependence Among Very Old European Women

To explore the impact of the sociocultural care and service context on dependence in instrumental activities of daily living, data were collected with 1448 very old women in 5 European countries. In addition, the influence of socioeconomic indicators was explored, using descriptive statistics and regression analyses. Highly significant differences concerning formal/informal support and use of mobi

Evaluation of the XRCC1 gene as a phenotypic modifier in BRCA1/2 mutation carriers. Results from the consortium of investigators of modifiers of BRCA1/BRCA2

BACKGROUND: Single-nucleotide polymorphisms (SNPs) in genes involved in DNA repair are good candidates to be tested as phenotypic modifiers for carriers of mutations in the high-risk susceptibility genes BRCA1 and BRCA2. The base excision repair (BER) pathway could be particularly interesting given the relation of synthetic lethality that exists between one of the components of the pathway, PARP1,

Inflammation marker and risk of pancreatic cancer: a nested case-control study within the EPIC cohort

BACKGROUND: Established risk factors for pancreatic cancer include smoking, long-standing diabetes, high body fatness, and chronic pancreatitis, all of which can be characterised by aspects of inflammatory processes. However, prospective studies investigating the relation between inflammatory markers and pancreatic cancer risk are scarce. METHODS: We conducted a nested case-control study within th

Large variation among photoreceptors as the basis of visual flexibility in the common backswimmer.

The common backswimmer, Notonecta glauca, uses vision by day and night for functions such as underwater prey animal capture and flight in search of new habitats. Although previous studies have identified some of the physiological mechanisms facilitating such flexibility in the animal's vision, neither the biophysics of Notonecta photoreceptors nor possible cellular adaptations are known. Here, we

Anesthesia and spinal muscle atrophy.

Spinal muscle atrophy (SMA) is autosomal recessive and one of the most common inherited lethal diseases in childhood. The spectrum of symptoms of SMA is continuous and varies from neonatal death to progressive symmetrical muscle weakness first appearing in adulthood. The disease is produced by degeneration of spinal motor neurons and can be described in three or more categories: SMA I with onset o

Evaluation of terrestrial carbon cycle models for their response to climate variability and to CO2 trends

The purpose of this study was to evaluate 10 process-based terrestrial biosphere models that were used for the IPCC fifth Assessment Report. The simulated gross primary productivity (GPP) is compared with flux-tower-based estimates by Jung etal. [Journal of Geophysical Research 116 (2011) G00J07] (JU11). The net primary productivity (NPP) apparent sensitivity to climate variability and atmospheric

Panitumumab and Pegylated Liposomal Doxorubicin in Platinum-Resistant Epithelial Ovarian Cancer With KRAS Wild-Type: The PaLiDo Study, a Phase II Nonrandomized Multicenter Study.

OBJECTIVE: The increasing number of negative trials for ovarian cancer treatment has prompted an evaluation of new biologic agents, which in combination with chemotherapy may improve survival. The aim of this study was to investigate the response rate in platinum-resistant, KRAS wild-type ovarian cancer patients treated with pegylated liposomal doxorubicin (PLD) supplemented with panitumumab. PATI

Testis dosimetry in individual patients by combining a small-scale dosimetry model and pharmacokinetic modeling-application of (111)In-Ibritumomab Tiuxetan (Zevalin(®)).

A heterogeneous distribution of radionuclides emitting low-energy electrons in the testicles may result in a significant difference between an absorbed dose to the radiosensitive spermatogonia and the mean absorbed dose to the whole testis. This study focused on absorbed dose distribution in patients at a finer scale than normally available in clinical dosimetry, which was accomplished by combinin

Nitrogen and Phosphorus Removal from Urine by Sequential Struvite Formation and Recycling Process

Recovering nutrients from urine as solid minerals such as struvite can eliminate many hurdles related to the use of liquid urine as fertilizer in the current urine separation systems. The focus of this study has been to increase nitrogen and phosphorus removal efficiencies by developing a struvite formation and recycling process. Struvite crystallization was carried out in urine samples by additio

Pure rotational Coherent anti-Stokes Raman spectroscopy of water vapor and its relevance for combustion diagnostics

In this work, we report for the first time the rotational coherent anti-Stokes Raman spectroscopy (CARS) spectrum of water vapor, recorded through experiments at 400K and 670K for Raman shifts up to 600cm(-1). Using the standard dual-broadband pure rotational CARS approach, the resonant structure was overwhelmed by a strong non-resonant background. By employing a polarization technique, this backg

Current global warming appears anomalous in relation to the climate of the last 20 000 years

To distinguish between natural and anthropogenic forcing, the supposedly ongoing global warming needs to be put in a longer, geological perspective. When the last ca. 20 000 yr of climate development is reviewed, including the climatically dramatic period when the Last Ice Age ended, the Last Termination, it appears that the last centuries of globally rising temperatures should be regarded as an a

alpha-synuclein antibodies recognize a protein present at lower levels in the CSF of patients with dementia with Lewy bodies

Background: Dementia with Lewy bodies (DLB) accounts for 15-20%, of the millions of people worldwide with dementia. Accurate diagnosis is essential to avoid harm and optimize clinical management. There is therefore an urgent need to identify reliable biomarkers. Methods: Mass spectrometry was used to determine the specificity of antibody alpha-synuclein (211) for alpha-synuclein. Using gel electro

Portfolio Saliency and Ministerial Turnover. Dynamics in Scandinavian Post-War Cabinets

Why do certain ministers remain in their post for years while others have their time in office cut short? Drawing on the broader literature on portfolio allocation, this article argues that the saliency of individual portfolios shapes ministerial turnover. The main argument is that ministerial dismissals are less likely to occur the higher the saliency attributed to the ministerial portfolio since

A review of the role of nurses and technicians in ST-elevation myocardial infarction (STEMI).

The role of nurses and technicians in the treatment of ST-elevation myocardial infarction (STEMI) by primary percutaneous coronary intervention (PPCI) is vital for the success of the multidisciplinary Heart Team. Several editorials have emphasised the importance of a holistic treatment which links each step of care to the next, a chain that is essential for quality and efficacy in the management o

Effect of Deglycosylation of Cellobiose Dehydrogenases on the Enhancement of Direct Electron Transfer with Electrodes

Cellobiose dehydrogenase (CDH) is a monomeric extracellular flavocytochrome composed of a catalytic dehydrogenase domain (DHCDH) containing flavin adenine dinucleotide (FAD), a cytochrome domain (CYTCDH) containing heme b, and a linker region connecting the two domains. In this work, the effect of deglycosylation on the electrochemical properties of CDH from Phanerochaete chrysosporium (PcCDH) and

Activating germline mutations in STAT3 cause early-onset multi-organ autoimmune disease.

Monogenic causes of autoimmunity provide key insights into the complex regulation of the immune system. We report a new monogenic cause of autoimmunity resulting from de novo germline activating STAT3 mutations in five individuals with a spectrum of early-onset autoimmune disease, including type 1 diabetes. These findings emphasize the critical role of STAT3 in autoimmune disease and contrast with

Wiring of pyranose dehydrogenase with osmium polymers of different redox potentials.

In this study, five different flexible osmium based redox polymers were investigated for their ability to efficiently "wire" the oxidoreductase pyranose dehydrogenase (PDH, EC 1.1.99.29) from Agaricus meleagris, on graphite electrodes for possible applications in biofuel cells. A series of newly synthesised osmium based redox polymers covering the potential range between -270 and +160mV vs. Ag|AgC
