Surface modification of reactive oxide substrates to obtain a less strongly interacting template for dye adsorption may be a way to enhance performance in dye-sensitized solar cells. In this work, we have investigated the electronic and structural properties of 4,4(')-bipyridine (bipy) as modifier adsorbed on the TiO2(110) surface. The modified surface is then coated with iron phthalocyanine (FePc

Dynamic artery blood pressure (Finapres) response to active standing up, normally consisting of initial rise, fall and recovery above the baseline (overshoot), was compared with the early steady-state artery blood pressure level to measure sympathetic vasomotor function in healthy subjects (n = 23, age 35 +/- 9 years; mean +/-SD) and in type I diabetic patients without autonomic neuropathy (AN) (g

Excessive interdialytic weight gain (IWG) and ultrafiltration rates (UFR) above 10 mL/h/kg body weight imply higher morbidity and mortality. This study aimed to estimate the prevalence of high fluid consumers, describe UFR patterns, and describe patient characteristics associated with IWG and UFR. The Swedish Dialysis DataBase and The Swedish Renal Registry of Active Treatment of Uremia were used

The still ever increasing demand for sedation and/or analgesia for diagnostic and therapeutic procedures puts high pressure on anaesthesia care providers all over Europe. Since the capacity to provide that service by anaesthetists is limited in most European countries, guidelines for non-anaesthetist doctors who want to sedate patients on a high-quality level and especially in a safe way are manda

The aim of the present study was to compare in man the innervation pattern and the functional responses to neuronal messengers in medium sized lenticulostriate and branches of the posterior cerebral arteries (PCA). The majority of the nerve fibers found were sympathetic and displayed specific immunoreactivity for tyrosine hydroxylase (TH) and neuropeptide Y (NPY). Only few nerve fibers displayed v

There is some evidence that birth weight is associated with breast cancer. Whether this association differs between premenopausal and postmenopausal ages is still unclear. The results from this study suggest that higher birth weight is a risk factor for postmenopausal breast cancer (OR 1.06, CI 1.00-1.12, per 100 g), independent of selected early-life and adult factors.

The aim of this study was to assess whether the TP53 Arg72Pro polymorphism is associated with an increased risk of non-small cell lung cancer (NSCLC). Additionally, in NSCLC patients, we investigated a potential association between this polymorphism and somatic TP53 gene mutations in tumour cells. The study group included 240 NSCLC patients who underwent curative pulmonary resection. The control g

Cellular susceptibility to fusion mediated by murine coronavirus (mouse hepatitis virus, MHV strain A59) was separated into lipid-dependent and lipid-independent mechanisms with the use of subclones and selected mutants of mouse L-2 fibroblasts. Fusion-resistant L-2 cell mutants had similar cholesterol and fatty acid composition as did their fusion-susceptible parent subclone, and were presumably

Objective To avoid ventilator induced lung injury, tidal volume should be low in acute lung injury (ALI). Reducing dead space may be useful, for example by using a pattern of inspiration that prolongs the time available for gas distribution and diffusion within the respiratory zone, the mean distribution time (MDT). A study was conducted to investigate how MDT affects CO2 elimination in pigs at he

Vincristine is a key drug in the treatment of childhood and adult acute lymphoblastic leukemia (ALL), and many other childhood malignancies. Despite decades of wide clinical use, no data on the correlation between vincristine pharmacokinetics and long-term clinical outcome have been published. We here report clinical data (median follow-up time 10.5 years, range 7.3-12 years) for 86 children with

Isolates of Colletotrichum, gloeosporioides associated with anthracnose disease oil coffee berries in Vietnam were characterized by morphological and molecular methods. Random amplified polymorphic DNA (RAPD) and microsatellite-primered PCR (MP-PCR) analyses were employed to investigate the genetic variation among 38 and 51 isolates of C. gloeosporioides, respectively. According to both methods, t

Among transcriptional regulatory proteins described, NF-kappaB seems particularly important in modulating the expression of immunoregulatory genes relevant in critical illness, inflammatory diseases, apoptosis, and cancer. In particular, NF-kappaB plays a central role in regulating the transcription of cytokines, adhesion molecules, and other mediators. The biochemical basis by which diverse stimu

The advantage of a new scheme for balanced detection has been investigated to reduce the influence of optical interference fringes when performing diode laser gas absorption spectroscopy employing lock-in amplifiers and pigtailed lasers. The influence of the fringes has been reduced by comparing the lock-in 2 f signal due to the gas sample with that of a reference beam. The frequency regions outsi

Common naturally occurring polymorphisms have been identified in the coding regions of the alpha(1A)-, alpha(2B)-, beta(1)- and beta(2)-adrenoceptor (AR) genes [alpha(1A)-AR R492C, alpha(2B)-AR insertion/deletion (I/D), beta(1)-AR R389G, beta(2)-AR G16R and beta(2)-AR Q27E] and are associated with modified in vivo and in vitro functionality. We tested their possible effects on the haemodynamic res

We examined the association between fruits and vegetables and risk of renal cell carcinoma (RCC) in the European Prospective Investigation into Cancer and Nutrition (EPIC). Dietary intake data and complete follow-up information on cancer incidence were available for 375,851 participants recruited in EPIC centers of 8 countries. During an average follow-up of 6.2 years, 306 incident cases of RCC we

During drying, timber changes its shape mainly due to shrinkage anisotropy, radial differences in longitudinal shrinkage and spiral grain. The warp, causing severe downgrading of the timber, can be reduced by restraint and appropriate climate treatments of different types. The research presented here is part of a larger project on the improvement of shape stability of Norway Spruce (Picea abies) b
