Abstract
Studies were carried out on eight obese (BMI 30-34.6 kg/m2) and seven age and sex-matched normal weight volunteers (BMI 20-25 kg/m2) to investigate the gastric emptying, mouth to caecum transit time (MCTT), plasma cholecystokinin (CCK) and sensory responses to high (30 g margarine; 1327 kJ (317 kcal)) and low (301 kJ (72 kcal)) fat soups. Gastric emptying was measured by gamma scintigraphy, MCTT was measured by the breath hydrogen technique, plasma CCK was measured using a bioassay technique and subjective sensations were recorded on visual analogue scales. The high fat meal emptied more slowly than the low fat meal in both the normal subjects (t1/2 = 86.3 +/- 9.2 vs. 36.7 +/- 2.8 min) but there were no differences in the emptying of either meal between the two groups of subjects. Increasing the fat content of the meal did not affect the mouth to caecum transit time (MCTT) in either group, nor were there differences between the groups in MCTT (180 +/- 23 vs. 188 +/- 35 min, normal vs. obese MCTT after low fat soup; 228 +/- 17 vs. 227 +/- 29 min, normal vs. obese MCTT after high fat soup). Despite similar rates of gastric emptying, the obese group showed a higher CCK production following the high fat meal than the normal weight group (540.4 +/- 65.9 vs. 336.9 +/- 51.4 pmol.min, 2 h integrated CCK production, obese vs. normal; P < 0.05). The obese group also reported feeling less hungry throughout the study than the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To obtain sufficient material for the biochemical and biophysical study of pp60c-src, we have utilized a recombinant pp60c-src baculovirus lacking the myristoylation site at codon 2. On infection of Sf9 cells, this virus produced large amounts of soluble non-myristoylated pp60c-src. The use of non-myristoylated pp60c-src (1) increases production of pp60c-src compared with the wild-type protein, (2) facilitates purification, (3) yields a stable product and (4) allows biochemical studies in the absence of detergents. Up to 20 mg of pp60c-src of greater than 95% purity has been purified from 6 litres of Sf9 cells grown in a bioreactor. One major and multiple minor forms of pp60c-src were separated by Mono Q f.p.l.c. Isoelectric focusing of purified pp60c-src species revealed heterogeneity, some of which could be attributed to differences in the tyrosine phosphorylation state of the enzyme. Kinetic analysis of non-myristoylated pp60c-src kinase in the presence of Mg2+ gave Km values for angiotensin II and ATP of 2 mM and 30 microM respectively and a Vmax. of 620 nmol/min per mg. The kinetic constants and metal ion preferences of a number of copolymers and peptide substrates have been compared. Polylysine and poly(GLAT), which was not phosphorylated by the pp60c-src kinase, dramatically activated autophosphorylation of Tyr-416, suggesting a conformation modulation of pp60c-src by charged polymers. This finding implies that Tyr-527 dephosphorylation is not sufficient for full activation of pp60c-src in vitro.

Abstract
Hand preference and hand skill were assessed in 20 children with autism, 20 normal controls and 12 children with mental retardation. 90% of the normal controls and 92% of the children with mental retardation showed concordance for hand preference and hand skill (i.e. the preferred hand was also the more skillful), whereas only 50% of the children with autism showed concordance of preference and skill, the remaining 50% preferring to use the hand which was less skillful. Children with autism also showed a lesser degree of handedness and a lesser degree of consistency than the other groups, although this was unrelated to the discordance of skill and asymmetry. A developmental model of handedness is proposed in which the development of handedness as preference is ontogenetically prior to the development of handedness as skill asymmetry, such that in normal children the development of skill asymmetry occurs as a secondary consequence of the establishment of preference. The causal sequence is disrupted in autism, so that although preference is established, it does not subsequently result in concordant skill asymmetry.

Abstract
Solid-phase ELISAs for the determination of EGF receptor (EGF-R) and pp60c-src tyrosine protein kinase activity are described. The methods were developed and optimized using purified recombinant EGF-R intracellular domain (ICD) and pp60c-src tyrosine protein kinases. A standardized assay that utilizes poly (GluNa-Tyr)4:1 as substrate and a monoclonal antiphosphotyrosine antibody for detection is described. Assay conditions for both enzymes were optimized with respect to substrate and ELISA plate-coating condition, divalent metal ion preferences, enzyme concentration, apparent kinetic constants for ATP, and reaction linearity. Following standardization, a number of reference tyrosine protein kinase inhibitors were tested in the ELISAs and compared to results obtained using solution-phase radioactive tyrosine protein kinase assays, which are based on the transfer of 32P from [gamma-32P]ATP to synthetic substrate. To enable a comprehensive comparison, IC50 values obtained in the ELISA were compared with values obtained in radioactive assays using both the holo-EGF-R and EGF-R ICD kinases. No substantial qualitative differences between these assays were seen. For many routine tyrosine protein kinase assays, semiquantitative or qualitative measurement of TPK activity is adequate. For such purposes, the ELISAs would be an attractive alternative to radioactive assays.

Abstract
ELISA capture assays were established for the E7 transforming proteins of HPV16 and HPV18, based on a range of previously characterised polyclonal and monoclonal antibodies. No cross-reactivity was observed in the ELISAs between HPV18 E7 and HPV16 E7. Immunoreactive E7 protein (iE7) was measured in a series of HPV-transformed cell lines, and ranged from 0.6 to 17.7 ng iE7/mg cell protein. iE7 was labile at 22 degrees C (t1/2 = 37 min) but relatively more stable at 4 degrees C (t1/2 = 210 min). HPV16 E7 protein at concentrations from 0.10 to 0.69 ng iE7/mg cell protein was detected in 5 of 13 smears from women with abnormal cervical cytology. Assay of E7 protein may play a role in the detection of HPV-induced cervical lesions with malignant potential.

Abstract
This paper reports on experiments designed to evaluate the performance of the equipotentials backprojection method under conditions modeling those of proposed applications of electrical impedance tomography. Small spherical targets were placed inside a saline-filled tank with dimensions similar to a human torso. Data were acquired with a computer-based instrument that applies current to pairs of electrodes located on two horizontal planes and records potential differences between electrodes of a third plane. The relative contrast produced by nonconducting spheres in a uniform saline background was measured on the reconstructed images and used to determine system sensitivity to target volume and to the radial and vertical positions of single spheres. Results show that for radial positions within a critical radius sensitivity is always maximum when the spheres center is on the recording plane and decreases gradually when the target is moved outside this plane. Localization of simple targets in 3-D, with data acquired from multiple recording planes, appears feasible. The results provide guidelines for the interpretation of images with complex 3-D conductivity distributions.

Abstract
We report two cases of heparin induced thrombocytopenia (HIT), in patients who required anticoagulation for extracorporeal procedures (haemodialysis and cardiopulmonary bypass) one associated with recurrent thrombosis of the artificial circuits. Resolution of thrombocytopenia and successful anticoagulation were achieved using a low molecular weight heparinoid (LMWH) Org 10172. Anticoagulation was monitored using estimations of plasma anti-factor Xa activity. These cases demonstrate that LMWH provides safe and effective anticoagulation in patients in whom unfractionated heparin has caused HIT.

Abstract
The dose due to Bremsstrahlung in stationary electron beams of nominal energies in the range 6-20 MeV is typically between 1-7% of the maximum dose and is usually not clinically significant. However, in treatments using rotational or multiple electron beams where the x-ray dose from several beams is added the x-ray dose will reach much higher proportions and will be of clinical significance. Moreover, this dose often is located in normal tissue beyond the target volume. Reduction of this x-ray dose is therefore desirable. In the present study a reduction of the x-ray component of electron beams produced by a Clinac 2100C accelerator by a change of the transmission ion chamber and scattering foils is reported. A reduction in Bremsstrahlung of up to 50% can be achieved.

Abstract
This feasibility study, based on intensive casework, examined the potential of home-based teleworking arrangements for people with severe physical disabilities. Eleven teleworking arrangements, each involving a unique combination of work, working conditions and worker characteristics, were set up in different parts of Ireland and monitored over periods ranging from 6 to 18 months. Eight were still operational at the end of the project and, with one exception, were set to continue as longer-term arrangements. Outcomes from this action-research project suggest that teleworking is a feasible form of employment for such persons--provided care is taken over selection of workers, identification of work that is suited to the telework format and management of telework units by employers. They also suggest that teleworking arrangements can be quite flexible, ranging from examples in which work is performed mainly from home to those which combine home-based activity with varying degrees of conventional office-based activity. It is concluded that telework will create new opportunities for people with severe disabilities, as well as enabling others who become disabled during employment to retain their jobs. However, it is important that workers are appropriately trained in the use of computers and advanced telecommunications and, in many cases, home-delivered training is required.

Abstract
F1 Offspring of hypertensive and normotensive rats (BHR) were reared with either hypertensive (SHR) or normotensive (WKY) cagemates, and observations were conducted at two developmental periods to assess the effects of rearing condition on the social environment and the behavior of BHR subjects. SHR displayed significantly more agonistic behavior during development than WKY, and BHR subjects reared with SHR were the targets of significantly more agonistic behavior than BHR subjects reared with WKY cagemates. BHR reared with SHR initiated twice as much agonistic behavior as BHR reared with WKY. When heart rate and blood pressure were assessed at 75-80 days of age, however, neither the alterations in developmental social environment nor the alterations in the behavioral characteristics of BHR were associated with differences in cardiovascular variables. The results do not support a causal connection between behavioral characteristics and cardiovascular outcome.

Abstract
On the basis of amino acid sequencing and immunological cross-reactivity, the Plasmodium falciparum parasitophorous vacuole antigens QF116 and exp-1/CRA are apparently identical. The epitope recognized by an inhibitory monoclonal antibody directed against QF116 is located proximal to the C-terminus of the protein. The QF116 protein is processed during maturation by the cleavage of a 22-amino-acid signal peptide and acylated as measured by labeling with myristic acid.

It has long been known that Crohn's disease may occur in association with certain forms of malignancy, specifically adenocarcinoma and lymphoma of the bowel and carcinoma of the vulva and perianal area. Here, the authors report the rare occurrence of extraintestinal Hodgkin's disease in a patient with documented regional enteritis of five years' duration. They propose explanations for this unusual combination of disease, reported in the literature only once previously, and review the pathophysiology of lymphoma and regional enteritis.

Abstract
We studied the pharmacodynamics of warfarin in chronically treated patients. Two methods were used to estimate the pharmacodynamic parameters M/Kd and Cmax (mg/L). In Method 1 the prothrombin time response was modeled directly without use of warfarin concentrations and Method 2 used warfarin concentrations and prothrombin time response to estimate M/Kd and Cmax. The mean Cmax and M/Kd for Method 1 (n = 88) were 5.5 +/- 2.3 mg/L and 51 +/- 46 and for Method 2 (n = 27) 6.3 +/- 2.8 mg/L and 35.4 +/- 13. When Method 1 was applied to the same 27 patients in Method 2, the mean Cmax and M/Kd were 5.7 +/- 3.3 mg/L and 36.1 +/- 14.9. These differences were not significant. Multiple regression analysis revealed that the value of Cmax and M/Kd varied between medical centers. No other patient characteristics were found to be significant. We conclude that modeling steady-state prothrombin time response directly adequately describes pharmacodynamic response to warfarin.

Abstract
Variants of mouse leukaemia L1210 cells have been isolated in which cytotoxicity to dimethyl sulphate is not fully potentiated by ADP-ribosyl transferase inhibitor 3-aminobenzamide, as occurs in normal L1210 cells. These variants were selected after mutagenesis by growing the cells in dimethyl sulphate and 3-aminobenzamide. The characterisation of one of these variants is described. Variant 3 cells repair low doses of DNA damage in the presence of ADP-ribosyl transferase inhibitors. The Vmax of the ADP-ribosyl transferase enzyme in these cells is only increased 35% compared to normal wild-type L1210 cells. The basal DNA ligase I activity is increased 66% above wild-type whereas DNA ligase II activity appears to be unchanged. The most striking observation, however, is that the DNA ligase II activity is not increased after dimethyl sulphate treatment as occurs in wild-type L1210 cells. It seems that by increasing DNA ligase I levels these cells can survive DNA damage in the presence of 3-aminobenzamide. This variant (mutant) provides genetic evidence for our previously published hypothesis that (ADP-ribose)n biosynthesis is required for efficient DNA repair after DNA damage by monofunctional alkylating agents, because ADP-ribosyl transferase activity regulates DNA ligase activity. This variant is the first mammalian cell reported in which DNA ligase activity is altered, as far as we are aware. In yeast, a DNA ligase mutant has a cell division cycle (cdc) phenotype. Presumably, DNA ligase is essential for DNA synthesis, repair and recombination. The present variant provides further evidence that in mammalian cells, DNA ligase II activity is related to ADP-ribosyl transferase activity.

Abstract
Methylphenidate-induced hepatic injury was documented by abnormal liver function tests including a markedly elevated serum bilirubin, serum glutamic oxaloacetic transaminase, and serum glutamic pyruvic transaminase. Liver biopsy confirmed portal inflammation and hepatocellular disarray. Enzyme changes were reproducible with rechallenge of the drug (Ritalin). The drug is capable of producing hepatic injury, particularly when given in nonstandard doses intravenously.

Abstract
In an attempt to assess cardiac risk in non-cardiac surgery, 1001 patients over 40 years of age who underwent major operative procedures were examined preoperatively, observed through surgery, studied with at least one postoperative electrocardiogram, and followed until hospital discharge or death. Documented postoperative myocardial infarction occurred in only 18 patients; though most of these patients had some pre-existing heart disease, there were few preoperative factors which were statistically correlated with postoperative infarction. Postoperative pulmonary edema was strongly correlated with preoperative heart failure, but 21 of the 36 patients who developed pulmonary edema did not have any prior history of heart failure. Nearly all of these 21 patients were elderly, had abnormal preoperative electrocardiograms, and had intraabdominal or intrathoracic surgery. In the absence of an acute infarction, bifascicular conduction defects, with or without PR interval prolongation, never progressed to complete heart block. Spinal anesthesia protected against postoperative heart failure but not against other cardiac complication. By multivariate regression analysis, postoperative cardiac death was significantly correlated with (a) myocardial infarction in the previous 6 months; (b) third heart sound or jugular venous distention immediately preoperatively; (c) more than five premature ventricular contractions per minute documented at any time preoperatively; (d) rhythm other than sinus, or premature atrial contractions on preoperative electrocardiogram; (e) age over 70 years; (f) significant valvular aortic stenosis; (g) emergency operation; (h) a 33% or greater fall in systolic blood pressure for more than 10 minutes intraoperatively. Notably unimportant factors included smoking, glucose intolerance, hyperlipidemia, hypertension, peripheral atherosclerotic vascular disease, angina, and distant myocardial infarction.

Abstract
The microwave region of the electromagnetic spectrum, a plausible regime for signals from extraterrestrial intelligences, is largely unexplored. With new technology, particularly in data processing and low-noise reception, surveys can be conducted over broad regions of frequency and space with existing antennas at flux densities plausible for interstellar signals. An all-sky, broad-band survey lasting perhaps 5 years can be structured so that even negative results would establish significant boundaries on the regime in which such signals may be found. The technology and techniques developed and much of the data acquired would be applicable to radio astronomy and deep-space communications.

Abstract
To determine which preoperative factors might affect the development of cardiac complications after major noncardiac operations, we prospectively studied 1001 patients over 40 years of age. By multivariate discriminant analysis, we identified nine independent significant correlates of life-threatening and fatal cardiac complications: preoperative third heart sound or jugular venous distention; myocardial infarction in the preceding six months; more than five premature ventricular contractions per minute documented at any time before operation; rhythm other than sinus or presence of premature atrial contractions on preoperative electrocardiogram; age over 70 years; intraperitoneal, intrathoracic or aortic operation; emergency operation; important valvular aortic stenosis; and poor general medical condition. Patients could be separated into four classes of significantly different risk. Ten of the 19 postoperative cardiac fatalities occurred in the 18 patients at highest risk. If validated by prospective application, the multifactorial index may allow preoperative estimation of cardiac risk independent of direct surgical risk.
