To measure in vivo the cadmium concentrations in kidney cortex (kidney-Cd) and in superficial liver tissue (liver-Cd) of nickel cadmium battery workers, and to compare the results with other commonly used estimates of cadmium exposure (current concentrations of cadmium in blood (B-Cd) and urine (U-Cd)) or repeated measurements of cadmium in workplace air (CumAir-Cd). METHODS: The study comprised 3

Colonisation by root endophytes can be beneficial to plants growing on acid, nutrient-poor soils. Arbuscular mycorrhizal (AM) fungi can supply herbs with nutrients and may give protection against aluminium toxicity. Two other root colonising fungi, fine endophytes (FE) and dark septate fungi (DSE), are less well known but are potentially of benefit to their host plant. AM fungi are the most preval

A Fourier-collocation scheme is used to approximate solutions to the generalized Benjamin-Ono equation u(t) + uP(Ux) - Hu(xx) = 0. The numerical simulation suggests that the equation features smooth solutions that become unbounded in finite time.

Light (LM) and transmission electron (TEM) microscopy were used to study previously specified ozone symptoms in the foliage of Norway spruce. The three youngest green needle generations from twenty mature trees in two stands on sites of different soil fertility at Asa, southern Sweden, were sampled in 1999. The critical dose of ozone, expressed as AOT40, was 6362 ppb.h. LM showed ozone-specific sy

Movements of individual articulators are analyzed to elucidate principles of gestural organization in vowels. Procedures for tracking articulator gestures from x-ray motion films, and results obtained on coarticulation in Swedish, Bulgarian, and Greenlandic are reported in Wood [J. Phon. 19, 281–292 (1991); Proc. 3rd Congr. I. C. P. L. A. 191–200, Helsinki (1994); Proc. 13th I. C. Ph. Sc. 1, 392–3

We have explored whether {gamma}-aminobutyric acid (GABA) is released by regulated exocytosis of GABA-containing synaptic-like microvesicles (SLMVs) in insulin-releasing rat pancreatic ß-cells. To this end, ß-cells were engineered to express GABAA-receptor Cl--channels at high density using adenoviral infection. Electron microscopy indicated that the average diameter of the SLMVs is 90 nm, that ev

A unique set of nanoparlicle dispersions of self-assembled lipid mesophases with distinctive reversed cubic, hexagonal, and sponge phase structures has been prepared by use of original lipid combinations and a simple, generally applicable and scalable method. All key properties, particle size distributions, shape, phase structure, and stability, are controlled predictably and reproducibly. The res

Using three cytotoxicity assays, we have investigated the effect of the spermine analogue N1,N11-diethylnorspermine (DENSPM)on four human breast cancer cell lines with different known genetic lesions. Cells were seeded in 96 well plates and DENSPM was added 24 h later to give final concentrations from 0.1 to 100 microM. At 24, 48 and 72 h of treatment, the protein content was determined with a mod

The vitamin K-dependent and ubiquitously expressed 82 kDa glycoprotein product of the growth-arrest-specific-gene 6, Gas6, shows 44% sequence identity to the anticoagulant protein, protein S. Both proteins share further the same domain organization. A short loop region, 4 epidermal growth factor-like modules and an SHBG-like region follow the N-terminal Gla-domain, which confers membrane-binding c

STUDY DESIGN: Prospective randomized longitudinal clinical trial with matched controls. OBJECTIVES: To investigate the long-term effect of training on postural control and extremity function after an acute anterior cruciate ligament (ACL) injury. BACKGROUND: ACL injuries may cause severe problems with recurrent giving way of the knee and reduced functional capacity. The effect of an acute ACL inju

BACKGROUND: The Arg389 variant of the beta(1)-adrenergic receptor gene mediates a higher isoproterenol-stimulated adenylate cyclase activity than the Gly389 variant in vitro. We investigated whether the Arg389Gly or the Ser49Gly polymorphism is associated with hypertension in Scandinavians. Methods and Results-- A total of 292 unrelated, nondiabetic, hypertensive patients and 265 unrelated healthy

Quick-release and quick-stretch experiments have been performed on preparations of smooth muscle from rat portal vein and rabbit urinary bladder. The low equivalent mass of the isotonic lever (8 mg) implied that inertial oscillations were limited to the first 5-10 msec after the load step. The high time resolution achieved in this way enabled us to separate three components in the length response

Children’s target experiences (as recipients of prosocial peer acts and victims of peer aggression) were investigated for their concurrent and longitudinal associations with prosocial and aggressive behavior. Forty-four children (initially 22–40 months) were observed in naturalistic interactions with peers during a two-month period for each of three consecutive years. Results revealed no consisten

Methods that objectively assess the muscle fibre-type arrangement may improve the detection of fibre-type grouping, a diagnostic sign of a denervation and reinnervation process. To distinguish between a diseased and a normal muscle, there is a need for quantitative data on the fibre-type arrangement in healthy human muscles at different ages. In this study, cross-sections were prepared of whole au

The influence of a small hydrophobic solute (octanoic acid) on the flux reduction and the flux recovery of two ultrafiltration membranes was studied in this investigation. The two membranes were made of polyether sulfone and regenerated cellulose, both with a nominal molecular weight cutoff of 20,000 Da. The concentration of the octanoic acid solution was found to have a significant influence on n
