We addressed the question of whether the autophagy pathway occurs in human peripheral nerves and whether this pathway is associated with peripheral neuropathy in diabetes mellitus. By using electron microscopy, we evaluated the presence of autophagy-related structures and neuropathy in the posterior interosseous nerve of patients who had undergone carpal tunnel release and had type 1 or type 2 dia

Anti-staling agents with different mechanisms were added to a normal white wheat bread to investigate the relation between bread staling, amylopectin retrogradation and water-related properties (i.e. water content and distribution between crumb and crust). Bread was baked both as pan-baked and freestanding loaves. The anti-staling agents maltogenic alpha-amylase, distilled monoglyceride and lipase

Purpose To determine if anti-retroviral therapy (ART) in HIV-infected patients is associated with an increased risk for development of abdominal wall hernia. Methods A cohort study of 1072 HIV-infected patients in Sweden. Information was collected by questionnaires to patients and treating physicians, chart reviews by study physicians and regular blood tests for metabolic disorders. Adjusted relat

PurposeTo analyse the relationship between patient-reported outcome measures and clinical outcome measures in 42 individual Swedish cataract surgery settings. MethodsThe study material consisted of follow-up data on cataract extractions collected by the Swedish National Cataract Register in 2008-2011. Patient-reported outcome was measured using the Catquest-9SF questionnaire. A total of 9707 pairs

Background: Previous studies of the natural history of alpha-1-antitrypsin (AAT) deficiency are mostly based on highly selected patients. The aim of this study was to analyse the mortality of PiZZ individuals. Methods: Data from 1339 adult PiZZ individuals from the Swedish National AAT Deficiency Registry, followed from 1991 to 2008, were analysed. Forty-three percent of these individuals were ide

Multigraft polymers comprise a subclass of branched polymers where more than one side chain is attached to each node (branching point) of the main chain. We have investigated structural properties of single multigraft polymers under good solvent conditions by Monte Carlo simulations, employing a flexible bead-spring model. Beside the grafting density, denoting the linear density of grafted side ch

Abstract As custom multicore architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-grap

The normalized differential cross section for top-quark pair production in association with at least one jet is studied as a function of the inverse of the invariant mass of the t (t) over bar + 1-jet system. This distribution can be used for a precise determination of the top-quark mass since gluon radiation depends on the mass of the quarks. The experimental analysis is based on proton-proton co

Aims and objectives: In this study, we investigated crosslinguistic influence in the phonetic systems of simultaneous bilinguals (2L1s) during adulthood. Methodology: Specifically, we analyzed the voice onset time (VOT) of the voiceless stop /k/ in the spontaneous speech of 14 German–French bilinguals who grew up in France or Germany. We looked at both languages, first comparing the groups, second

Research aimed at developing new therapies for Parkinson's disease (PD) critically depend on valid animal models of the disease that allows for repeated testing of motor disabilities over extended time periods. We here present an extensive characterization of a wide range of motor symptoms in the 6-OHDA marmoset model of PD when tested over several months. The severity of motor deficits was quanti

The opacity of the Earth to incident ultrahigh energy neutrinos is directly connected with the behavior of the neutrino-nucleon (sigma(nu N)) cross sections in a kinematic range utterly unexplored. In this work we investigate how the uncertainties in sigma(nu N) due the different QCD dynamic models modify the neutrino absorption while they travel across the Earth. In particular, we compare the pre

IL-22 is a recently discovered cytokine that belongs to the family of IL-10 related cytokines. It is produced by activated T-cells and innate lymphoid cells and has been suggested to be involved in tissue repair. As both inflammation and repair play important roles in atherosclerosis we investigated if IL-22 deficiency influences the disease process in Apoe(-/-) mice.

Research about the prevalence of underweight and overweight/obesity in the Saudi Arabian female population is limited. The aim of the present study was to examine the dietary habits and the prevalence of underweight and overweight/obesity and associated factors among female university students.

Proteins and other biomolecules contain acidic and basic titratable groups that give rise to intricate charge distributions and control electrostatic interactions. 'Charge regulation' concerns how the proton equilibria of these sites are perturbed when approached by alien molecular matter such as other proteins, surfaces and membranes, DNA, polyelectrolytes etc. Importantly, this perturbation gene

BACKGROUND: Dopamine depletion of the striatum is one of the hallmarks of Parkinson's disease. The loss of dopamine upregulates GAD67 expression in the striatal projection neurons and causes other changes in the activity of the basal ganglia circuit. METHODS: To normalize the GAD67 expression in the striatum after dopamine depletion we developed several lentiviral vectors that express RNAi directe

In the last few decades, Western governments have spent huge sums of money to promote democracy abroad. We do not know which, if any, of these programs actually work. If we cannot measure democracy in sufficient detail and with the necessary nuance, we cannot mark its progress and setbacks or affect its future course. While distinguishing the most democratic countries from the least democratic one

We present a study of tail-bias-current 1/f noise upconversion into 1/f(3) phase noise for both CMOS Colpitts and differential-pair LC oscillators. We focus on the incremental Groszkowski effect, i.e., the modulation of the shift in oscillation frequency induced by the higher current harmonics flowing into the LC tank of a harmonic oscillator induced by bias instabilities, as we show that there is

The loss of aroma components after drying the fruit of Vangueria infausta L. was studied by means of convective air drying and gas chromatography techniques. The samples were dried at 80 degrees C, with an air flow of 3m/s at different drying times in the range of 60 up to 420min. Aroma composition, dry matter, and water activity were measured for each sample throughout the drying time. The study
