Time courses in visual-information processing: some empirical evidence for inhibition.
Hagenzieker MP, van der Heijden AH, Hagenaar R
In the literature two different views on the time course of activation of "recognition units"--hypothetical units that represent identity information--are proposed. The first view assumes that the recognition units accumulate activation gradually over time. The second assumes that the activation levels increase fast initially and then start to decrease. Hagenzieker and Van der Heijden (1990) have proposed a more general information-processing model, which is compatible with both views....

The information-processing approach.
van der Heijden AH, Stebbins S
The information-processing (IP) approach to perception and cognition arose as a reaction to behaviourism. This reaction mainly concerned the nature of explanation in scientific psychology. The "standard" account of behaviour, phrased in strictly external terms, was replaced by a "realist" account, phrased in terms of internal entities and processes. An analysis of the theoretical language used in IP psychology shows an undisciplined state of affairs. A great number of languag...

Frequency and degree of aneuploidy in benign and malignant thyroid neoplasms.
Schelfhout LJ, Cornelisse CJ, Goslings BM, Hamming JF, Kuipers-Dijkshoorn NJ, van de Velde CJ, Fleuren GJ
The frequency and degree of aneuploidy in 44 benign and 124 malignant thyroid neoplasms were analyzed by DNA flow cytometry. Single aneuploid cell populations were found in 72% of the undifferentiated carcinomas, 64% of the follicular carcinomas, 24% of the papillary carcinomas and in 24% of the follicular adenomas. Multiple aneuploid cell populations were detected in 4% of the papillary and in 36% of the follicular carcinomas but not in undifferentiated carcinomas. A low degree of aneuploidy wa...

The value of fine-needle aspiration biopsy in patients with nodular thyroid disease divided into groups of suspicion of malignant neoplasms on clinical grounds.
Hamming JF, Goslings BM, van Steenis GJ, van Ravenswaay Claasen H, Hermans J, van de Velde CJ
The accuracy of clinical diagnosis and fine-needle aspiration biopsy (FNAB) was evaluated in 169 patients surgically treated for nodular thyroid disease. Patients were divided into three groups with high, moderate, or low suspicion of malignant neoplasms on clinical grounds without previous knowledge of cytologic or histologic results. Histologic examination revealed an overall malignant neoplasm rate of 23%; the rate was 71%, 14%, and 11% for the groups with high, moderate, and low suspicion, r...

Early and late arterial healing response to catheter-induced laser, thermal, and mechanical wall damage in the rabbit.
Oomen A, van Erven L, Vandenbroucke WV, Verdaasdonk RM, Slager CJ, Thomsen SL, Borst C
Pulsed lasers are being promoted for laser angioplasty because of their capacity to ablate obstructions without producing adjacent thermal tissue injury. The implicit assumption that thermal injury to the artery is to be avoided was tested. Thermal lesions were produced in the iliac arteries and aorta of normal rabbits by a) electrical spark erosion, b) the metal laser probe, and c) continuous wave neodymium-yttrium aluminum garnet (Nd-YAG) laser energy through the sapphire contact probe. High-e...

[Use of electronic data processing at a urologic polyclinic--a program packet for recording and evaluating data of specialized consultations].
Schneider AW, Otto U, Conrad S, Klosterhalfen H
A software package was developed for computerized recording and processing of clinical data in a urological out-patient clinic. In a pilot study this program proved to be useful for the rapid evaluation of all important clinical and laboratory results of patients with renal cell carcinoma, and its use also accelerated the preparation of medical reports. The experience gained in this initial project shows that the application of this newly developed concept of data processing can easily be extend...

Experimental electrophysiology and arrhythmogenicity. Anisotropy and ventricular tachycardia.
Allessie MA, Schalij MJ, Kirchhof CJ, Boersma L, Huybers M, Hollen J
In a 2-D model of anisotropy, created by freezing the intramural and endocardial layers of a Langendorf perfused rabbit heart, sustained ventricular tachycardia (VT) with a cycle length of 130 ms and an excitable gap of 30 ms could be initiated by rapid pacing. High resolution mapping (256 points) of the thin surviving epicardial layer revealed that the VT was based on epicardial re-entry without the involvement of a gross anatomic obstacle and a central line of functional conduction block orien...

Prognosis and morbidity after total thyroidectomy for papillary, follicular and medullary thyroid cancer.
Hamming JF, Van de Velde CJ, Goslings BM, Schelfhout LJ, Fleuren GJ, Hermans J, Zwaveling A
The prognosis and the morbidity results after total thyroidectomy are reported for 148 patients with differentiated thyroid cancer. Ninety-two patients (62%) had papillary cancer, 27 (18%) had follicular cancer and 29 (20%) had medullary cancer. In the latter group, 16 patients had no clinical signs of a tumour and underwent total thyroidectomy after elevated calcitonin levels were found in a family screening programme. The mean follow-up period was 9.7 years in the present series. The 5- and 10...

[Quantitative immunocytology as a marker for indications and follow-up of recurrence prevention of superficial urinary bladder cancers].
Schneider AW, Huland E, Huland H
In 1985, we initiated a prospective clinical trial to evaluate the risk of recurrence for superficial bladder cancer. Up to now, 41 patients subjected to TUR have subsequently been monitored by immunocytology with a monoclonal antibody (mab 486 p) recently developed in our laboratory. Of these patients, 15 (36.6%) remained marker-negative and received no prophylactic therapy. There was only one recurrence (6.7%) in this subset of patients, whereas 10 out of 26 (38.5%) marker-positive patients ha...

Peroperative diagnosis and treatment of metastases to the regional lymph nodes in papillary carcinoma of the thyroid gland.
Hamming JF, van de Velde CJ, Goslings BM, Fleuren GJ, Hermans J, Delemarre JF, van Slooten EA
The management of two groups of patients with papillary carcinoma of the thyroid gland (n = 165) was evaluated retrospectively. Total thyroidectomy was the standard procedure in both groups, but the peroperative diagnosis and treatment of metastases to the regional lymph nodes differed. In group 1 (n = 84), only clinically positive lymph nodes were resected, and if residual postoperative 131I uptake was found, an ablation dose of 131I was given. In group 2 (n = 81), all of the tissue in the trac...

Changes in nonmyocyte tissue composition associated with pressure overload of hypertrophic human hearts.
Huysman JA, Vliegen HW, Van der Laarse A, Eulderink F
To investigate whether pressure-overloaded left ventricular hypertrophy is associated with changes in tissue composition of left ventricular subendocardial (ENDO) and subepicardial (EPI) myocardium, we studied post-mortem 19 normal hearts, 17 hearts of patients with systemic hypertension, and 5 hearts of patients with aortic stenosis. Coronary artery disease was present in 9 hearts of the hypertension group and all 5 hearts of the aortic stenosis group. By means of a grid-point method, volume pe...

Improvement of hepatitis B-associated glomerulonephritis after antiviral combination therapy.
de Man RA, Schalm SW, van der Heijden AJ, ten Kate FW, Wolff ED, Heijtink RA
A 9-year-old boy with hepatitis B-associated glomerulonephritis and nephrotic syndrome underwent antiviral combination therapy including interferon and acyclovir. Pretreatment evaluation showed that active hepatitis B virus replication with HBsAg, HBeAg, HBV-DNA and DNA-polymerase had occurred for a period of at least 4 years. Signs of liver disease were minimal; serum amino transferases were normal and liver histology showed chronic persistent hepatitis with positive HBcAg, HBeAg and HBsAg immu...

Detection and identification of FaeC as a minor component of K88 fibrillae of Escherichia coli.
Oudega B, de Graaf M, de Boer L, Bakker D, Vader CE, Mooi FR, de Graaf FK
A tribrid gene containing ompF, faeC, and lacZ sequences was constructed by subcloning a large central segment of the K88ab gene encoding the fibrillar subunit-like protein FaeC into the open reading frame expression vector pORF2. The resulting tribrid protein was isolated and used to raise antibodies against the FaeC protein. These antibodies were then used for the detection and subcellular localization of the FaeC protein in Escherichia coli harbouring the K88ab-encoding plasmid pFM205 or muta...

[Schwannoma (neurilemmoma): a case report].
Yavuz GE, Yilmaz D, Oygür T
Neurilemmoma, neurofibroma and neuroma are benign neoplasms of nerve tissue. These arise from components of the peripheral nerves. They are extremely rare within the jaws. Schwannoma or neurilemmoma may occur along the route of any of the peripheral cranial or sympathetic nerves. The source of origin is thought to be the schwann cells. Its appearance in oral and paraoral regions is not rare. Treatment is surgical and the prognosis is excellent. It has no tendency toward recurrence. Our schwannom...

Comparison of myocardial changes between pressure induced hypertrophy and normal growth in the rat heart.
van der Laarse A, Vliegen HW, van der Nat KH, Hollaar L, Egas JM, Swier GP, van den Broek AJ
To evaluate differences in tissue composition between hearts with pressure overload hypertrophy and normal hearts of comparable weight, 30 rat hearts with aortic constriction of 4, 10 and 30 days, and nine hearts of sham operated controls were studied. Surgery was performed at age 70 days. Morphometric analysis of myocardial tissue sections revealed (1) myocyte hypertrophy in left ventricular myocardium of hypertrophic hearts was proportional to heart weight, and in normal growth myocyte volume...

Myocardial (iso)enzyme activities, DNA concentration and nuclear polyploidy in hearts of patients operated upon for congenital heart disease, and in normal and hypertrophic adult human hearts at autopsy.
van der Laarse A, Hollaar L, Vliegen HW, Egas JM, Dijkshoorn NJ, Cornelisse CJ, Bogers AJ, Quaegebeur JM
To investigate biochemical characteristics of hypertrophic myocardium of young and adult humans, we analysed myocardial biopsies obtained from 28 mainly young patients undergoing cardiac surgery for congenital heart disease and 41 autopsied hearts from 18 adult normal and 23 hypertrophic human subjects. Myocardial activities of the enzymes creatine kinase and lactate dehydrogenase were independent of age during childhood, but decreased significantly with hypertrophy at adult age. Myocyte nuclei...

Context-dependent migrations in visual word perception.
van der Velde F, van der Heijden AH, Schreuder R
In the present study we investigate the effect of context--that is, a prime--on migration errors. Migration errors, or migrations, are caused by perceptual interactions between two words in a visual display, such as line-lace. After postcuing, subjects sometimes report lane or lice, instead of the requested word line. This phenomenon has been demonstrated by previous studies. In the experiments reported here, we replicate this phenomenon. We also find that more migrations of the lane type occur...
