Pressure-volume (p-V) relationships of a segment of the forearm circulation have been measured in nine male healthy subjects. Forearm volume was measured using electrical impedance plethysmography, arterial transmural pressure by subtracting mean arterial pressure measured contralaterally in a finger from the pressure in a cuff placed over the...

Objective. Arterial pressure waveforms distort between brachial and finger arteries, causing differences mainly in systolic pressure. Distortion, reportedly, can be removed by applying a waveform filter to the finger pressure. Design. We analysed the data from two studies that detected discrepancies in systolic tracking between Finapres and...

Increased plasma factor VII coagulant activity (FVII:C) has been associated with the risk of ischemic heart disease (IHD). Differences in plasma FVII:C among individuals are associated with three common polymorphisms in the FVII gene. Therefore, we investigated FVII polymorphisms in four populations that differ in their risk of developing...

While non-reactivability of cholinesterase from their phosphyl conjugates (aging) is attributed to an unimolecular process involving loss of alkyl group from the phosphyl moiety, no conclusive evidence is available that this is the only reaction path and involvement of other post-inhibitory processes cannot be ruled out, To address this issue,...

The question of whether melanins are photoprotecting and/or photosensitizing in human skin cells continues to be debated. To evaluate the role of melanin upon UVA irradiation, DNA single-strand breaks (ssb) were measured in human melanocytes differing only in the amount of pigment produced by culturing at two different concentrations, basic (0...

In the Netherlands, the nationwide Fat Watch campaign aiming at a reduction in fat consumption was organized from 1991 onwards. This study describes the effects of the first three consecutive campaign years on attention to fat, diet and health, attitudes, self-efficacy expectations and intentions related to dietary fat reduction, and self-rated...

Background: Peanuts are a major cause of food allergies both in children as in adults which can induce an anaphylactic shock. The identification and characterization of peanut allergens could lead to more insight into the mechanism and contribute to the improvement of diagnostic tests and treatment for peanut allergy. Objectives: In the present...

An HPLC assay with tandem mass spectrometric detection in the positive-ion Turbo-Ion-Spray((TM)) (TISP) mode for the fast and sensitive determination of perifosine ((I), D-21266) in human plasma was developed, utilising the structural analogue, miltefosine ((II), D-18506), as internal standard. Automated solid-phase extraction of diluted plasma...

Hazelnuts are widely used in the food industry owing to their nutritive value and taste. The amount of hazelnut present in a recipe is usually considered as a mark of quality. On the other hand, contamination of foods that normally do not contain hazelnuts is a threat for patients with a hazelnut allergy. For this reason, the availability of a...

The relationship between aortic flow and pressure is described by a three-element model of the arterial input impedance, including continuous correction for variations in the diameter and the compliance of the aorta (Modelflow). We computed the aortic flow from arterial pressure by this model, and evaluated whether, under orthostatic stress,...

The development of procedures for retrospective detection and quantitation of exposure to phosgene, based on adducts to hemoglobin and albumin, is described. Upon incubation of human blood with [14C]phosgene (0-750 μM), a significant part of radioactivity (0-13%) became associated with globin and albumin. Upon Pronase digestion of globin, one of...

Oscillometric blood pressure devices tend to overestimate systolic blood pressure and underestimate diastolic blood pressure compared with sphygmomanometers. Recent studies indicate that discrepancies in performance between these devices may differ between healthy and diabetic subjects. Arterial stiffness in diabetics could be the underlying...

Objective. Assessing whether the initiation of insulin therapy in patients with diabetes mellitus type 2 can be delivered as effectively in a structured transmural care model as in the more usual outpatients structure. Design. Retrospective comparative cohort study. Method. In 1997 data were collected from 52 patients with diabetes mellitus type...

Monoclonal antibody (mAb) III-3b binds D-dimer with Kd = 1.4 × 10-10 M without cross-reaction with fibrin(ogen). The epitope for this mAb is in Bβ134-190, presumably in Bβ155-160. The latter site is buried in the coiled coil structure of fibrin(ogen) but it is exposed as a neoantigenic determinant in D-dimer upon plasmic lysis of fibrin. mAb III...

A generic method was developed for the fast determination of a wide range of drugs in serum or plasma. The methodology comprises generic solid-phase extraction, on-line coupled to gradient HPLC with tandem mass spectrometric detection (SPE-LC-MS/MS). The individual components of the SPE-LC-MS/MS system were optimized in an integrated approach to...

Despite a ban by the European Union, the use of anabolic steroids and repartitioning agents in cattle is still occasionally observed. Due to continuing improvements in analytical techniques, very low detection limits for individual compounds have been achieved. In response to these developments, cocktails composed of several steroids have been...
