Influence of plasmatic lipids on the hemorheological profile in healthy adults.

Some hemorheological parameters constitute risk factors for ischemic cardiovascular events. Most of these hemorheological factors are determined by the erythrocyte intrinsic properties and the high molecular weight plasmatic proteins, especially fibrinogen. The contribution of the plasmatic lipids to hemorheological factors is not well established. With this aim we determined hemorheological parameters in 112 healthy volunteers (62 males, 50 females) aged 35+/-10 years, range 19-54 years, members of our hospital staff. A complete set of rheological test was performed. Blood viscosity (BV) 230 sec(-1), plasma viscosity (PV), erythrocyte aggregation index (EAI), erythrocyte elongation index (EEI), hematocrit and fibrinogen. We also determined plasmatic lipids including total cholesterol (T-Ch) and its fractions (HDL-Ch, LDL-Ch, VLDL-Ch), triglycerides, lipoproteins (Apo B, Apo A(1), B/A(1)). Exclusion criteria were concomitant cardiovascular risk factors or any other associated pathology. Our results show a positive correlation between BV 230 sec(-1) and triglycerides (r=0.335) and negative with HDL-Ch (r=-0.451) (p=0.01), respectively; PV shows a positive correlation with T-Ch (r=0.297), LDL-Ch (r=0.298) and Apo B/A (r=0.290) (p=0.01). The EEI was negatively correlated with TG (p=0.05). Of all the rheological parameters evaluated, EAI is the factor which shows the highest significant correlation with plasmatic lipids: T-Ch (r=0.515), TG (r=0.303), LDL-Ch (r=0.507) and Apo B/A ratio (r=0.403); (p=0.01). These results suggest that plasmatic lipids contribute to modulate the blood rheological properties, slowing blood flow, favouring the development of atherothrombotics events, especially in stenotic areas or bifurcations in the vascular tree.

Validation of eating and dieting expectancy measures in two adolescent samples.

OBJECTIVE: To demonstrate the validity of two measures of eating and dieting expectancies (The Eating Expectancy Inventory [EEI] and the Thinness and Restricting Expectancy Inventory, [TREI]) for use with adolescents. METHOD: Seventh (N = 392) and tenth graders (N = 300) completed the Bulimia Test-Revised (BULIT-R), the Eating Disorder Inventory (EDI-II), and two factors of the Three-Factor Eating Questionnaire (TFEQ). RESULTS: Findings replicated for the two adolescent samples. The expectancy that thinness leads to overgeneralized life improvement correlated with measures of "successful" dieting, dieting plus disinhibition, and bulimic symptomatology. Expectancies for negative reinforcement from eating (e.g., eating helps manage negative affect and alleviate boredom) correlated with dieting plus disinhibition and bulimic symptoms, but not with successful dieting. Negative reinforcement from eating and reinforcement from thinness expectancies accounted for different bulimic symptom variance than that accounted for by the personality factors of perfectionism, interpersonal distrust, and ineffectiveness. DISCUSSION: Results were consistent with prior work on college and clinical samples, thus supporting use of the expectancy measures with adolescents.

Binding of a high affinity phosphotyrosyl peptide to the Src SH2 domain: crystal structures of the complexed and peptide-free forms.

The crystal structure of the Src SH2 domain complexed with a high affinity 11-residue phosphopeptide has been determined at 2.7 A resolution by X-ray diffraction. The peptide binds in an extended conformation and makes primary interactions with the SH2 domain at six central residues: PQ(pY)EEI. The phosphotyrosine and the isoleucine are tightly bound by two well-defined pockets on the protein surface, resulting in a complex that resembles a two-pronged plug engaging a two-holed socket. The glutamate residues are in solvent-exposed environments in the vicinity of basic side chains of the SH2 domain, and the two N-terminal residues cap the phosphotyrosine-binding site. The crystal structure of Src SH2 in the absence of peptide has been determined at 2.5 A resolution, and comparison with the structure of the high affinity complex reveals only localized and relatively small changes.

Screening and analysis of bioactive compounds in traditional Chinese medicines using cell extract and gas chromatography-mass spectrometry.

As the cost of drug development is always many times more than that of drug discovery, predictive methods aiding in the screening of bioavailable drug candidates are of profound significance. In this paper, a novel method for screening bioactive compounds from traditional Chinese medicines (TCMs) was developed by using living cell extract and gas chromatography (GC)-mass spectrometer (MS). The method was validated by using elemene emulsion injection (EEI), a typical TCM with known active compound, to interact with murine ascites hepatocarcinoma cell strain with high metastatic potential (HCa-F). Finally, the method was applied to screen the bioactive compounds from multi-component zedoary turmeric oil and glucose injection (ZTOGI). After HCa-F cells was incubated in ZTOGI, ethyl acetate (EtOAc) was used to extract the compounds in the cells for GC-MS analysis. Fourteen compounds were detected in the desorption eluate of HCa-F cell extract of ZTOGI, and further identified by MS. Curzerene and beta-elemene were found to be two major bioactive compounds in ZTOGI. These results show that the method developed may be applied to quickly screen the potential bioactive components in TCMs interacting with the target cells.

Kinetics of a model for zymogen activation: the case of high activating enzyme concentrations.

Transient phase and steady state equations have been derived for the following enzyme activation mechanism: (formula; see text) in which the concentrations of activating enzyme, E, and substrate, A, are greatly in excess of that of zymogen, Ei. EEi, EEa, EaA and EaY are four intermediates; W is a peptide related from Ei during EEa formation and X and Y are the products of Ea reaction on A. From the general equations, approximate solutions under certain simplifying conditions have been derived. Finally, some formal particular cases of the above mechanism are considered.

Survival of the endodontic endosseous implant.

The endodontic endosseous implant (EEI) enjoyed wide use in the United States after it was introduced in the 1960's. For various reasons including incorrect case selection, improper use of the materials, and poor preparation for the implant a high number of failures resulted. Following opposition by some members of the dental community, the procedure fell into disuse. The authors of this article had treated a number of cases with the endodontic endosseous implant from 1965 to 1975, many of which did fail. However, we have noted some remarkable very long-term successes with the technique, two of which are presented here. We suggest that the endodontic endosseous implant should not be discarded totally, but, with further research to improve the materials and technique, it still may be used in carefully selected cases.

Bacteriological features and chemotherapy of adult acute purulent otitis media.

Eighty-eight patients from 16 to 79 years old, with acute purulent otitis media, were bacteriologically examined at the Otorhinolaryngology Department of a primary care hospital in Tokyo from July 1979 to May 1983. Fifty-six patients underwent paracentesis, and 32 patients exhibited otorrhea due to previous spontaneous perforation of the tympanic membrane. Bacteriologic cultures revealed the presence of Streptococcus pneumoniae (62.5 per cent), including S. pneumoniae Type III (28.1 per cent), Haemophilus influenzae (10.5 per cent), Staphylococcus aureus (11.5 per cent), and Streptococcus pyogenes (7.3 per cent). S. pneumoniae Type III had a notably high detection rate in patients from 50 to 79 years old (50-75 per cent). Because Haemophilus influenzae was detected at a relatively high rate in patients of all ages, if can be considered as a major causative pathogen of AOM. In 44 patients, selected mainly from those who underwent paracentesis, a comparative study of bacteria found in middle ear fluid and naso-pharyngeal mucus revealed the same bacteria in 43 out of 44 cases (97.7 per cent), indicating the presence of bacterial infection through the auditory canal. Antibiotics were selected according to an Expected Efficacy Index (EEI), the antibiotic of first choice being Ampicillin or Cefaclor.

Recognition of a high-affinity phosphotyrosyl peptide by the Src homology-2 domain of p56lck.

The Src homology-2 (SH2) domains are modules of about 100 amino-acid residues that are found in many intracellular signal-transduction proteins. They bind phosphotyrosine-containing sequences with high affinity and specificity, recognizing phosphotyrosine in the context of the immediately adjacent polypeptide sequence. The protein p56lck (Lck) is a Src-like, lymphocyte-specific tyrosine kinase. A phosphopeptide library screen has recently been used to deduce an 'optimal' binding sequence for the Lck SH2 domain. There is selectivity for the residues Glu, Glu and Ile in the three positions C-terminal to the phosphotyrosine. An 11-residue phosphopeptide derived from the hamster polyoma middle-T antigen, EPQpYEEIPIYL, binds with an approximately 1 nM dissociation constant to the Lck SH2 (ref. 17), an affinity equivalent to that of the tightest known SH2-phosphopeptide complex. We report here the high-resolution crystallographic analysis of the Lck SH2 domain in complex with this phosphopeptide. Recent crystallographically derived structures of the Src SH2 domain in complex with low-affinity peptides, which do not contain the EEI consensus, and NMR-derived structures of unliganded Abl (ref. 19) and p85 (ref. 20) SH2 domains have revealed the conserved fold of the SH2 domain and the properties of a phosphotyrosine binding pocket. Our high-affinity complex shows the presence of a second pocket for the residue (pY + 3) three positions C-terminal to the phosphotyrosine (pY). The peptide is anchored by insertion of the pY and pY + 3 side chains into their pockets and by a network of hydrogen bonds to the peptide main chain. In the low-affinity phosphopeptide/Src complexes, the pY + 3 residues do not insert into the homologous binding pocket and the peptide main chain remains displaced from the surface of the domain.

Does degree of obesity influence the validity of reported energy and protein intake? Results from the SOS Dietary Questionnaire. Swedish Obese Subjects.

OBJECTIVE: To test the validity of a dietary questionnaire which was developed with the particular goal of measuring dietary intake in obese subjects. DESIGN: Reported energy intake was compared with 24 h energy expenditure measured in a chamber for indirect calorimetry (24 EE) and reported nitrogen intake with nitrogen in urine collected during the 24 h in the chamber. SUBJECTS: Twenty-nine overweight men and women, body mass index (BMI) ranging from 25.5 49.5 kg/m2. RESULTS: Reported energy intake correlated significantly with 24 EE (r = 0.50, P = 0.006) and reported urinary nitrogen correlated significantly with urinary nitrogen excretion (r=0.56, P=0.0015). Mean reported energy intake+/-s.d. was 10.2+/-3.6 MJ and mean 24 EEi s.d. was 10.3+/-1.9 MJ. Although this difference was small and non significant, it indicates some underreporting if one can assume that these overweight subjects are less physically active in the chamber than in free-living conditions. Reported nitrogen intake also suggested underreporting at the group level. However, when the data were analysed at the individual level it was clear that the underreporting errors did not increase with increasing degree of obesity. CONCLUSIONS: Previous studies with the SOS dietary questionnaire have demonstrated that it is possible to obtain plausible energy intakes from both obese and nonobese subjects. This present analysis further demonstrates that the questionnaire discriminates overweight subjects with high and low intakes of energy and protein, using unbiased biomarkers to judge validity. These data provide additional support for the usefulness of the SOS dietary questionnaire.

Use of enzyme overlay membranes to survey proteinase activity in frozen sections: cathepsin-like and plasmin-like activity in regenerating newt limbs.

We present a method that permits extremely simple and rapid screening of proteolytic enzyme activity in sectioned tissues. Enzyme overlay membranes (EOMs) are custom-made membranes designed to fluoresce at sites of specific proteolytic enzyme activity after separation of proteins by gel electrophoresis. EOMs, selected to detect either plasmin-like or cathepsin B-like activity, have been used in a novel way to document the distribution of enzyme activity in frozen sectioned tissues. When moistened membranes were placed in contact with sectioned regenerating newt limbs, a fluorescent pattern of enzyme activity was generated. In limbs at 3 hr post amputation, cathepsin B-like activity was prominent across the amputation site but plasmin-like activity was distributed in dermal and deeper proximal tissues, suggesting different roles for these two classes of enzymes. EOM enzymology in situ (EEI) on frozen sectioned tissues may be a widely useful technique to display distribution and level of activity of proteolytic enzymes in various systems.

Comparison of the Easy Strutter Functional Orthosis System and axillary crutches during modified 3-point gait.

The Easy Strutter Functional Orthosis System (ESFOS) was designed to improve assistive device ambulatory efficiency. This crossover design study compared the ESFOS to axillary crutches during modified 3-point gait. Thirty-eight subjects (40-65 years of age) at > 1 year after unilateral total knee or hip replacement participated in this study. Heart rate, mean peak palmar and plantar force magnitude, and onset timing were monitored during self-directed pace ambulation. Between trials, subjects responded to questions on perceived exertion, stability/security, and comfort. One-way analyses of variance were used to evaluate condition differences for ratio or interval data (p < or = 0.01). Statistically significant differences were noted for mean peak palmar forces (reduced 45% and delayed 31%), mean peak plantar force onsets (delayed 30%), and energy expenditure index (EEI) (reduced 25%). Wilcoxon signed rank tests were used to evaluate condition differences for ordinal data. Subjects preferred the ESFOS to axillary crutches for comfort and security/stability on flat surfaces and stairs (p < or = 0.001). Results suggest greater ambulatory gait efficiency during ESFOS use. Further study is indicated with other patient populations.

Electromyographic differentiation of diplegic cerebral palsy from idiopathic toe walking: involuntary coactivation of the quadriceps and gastrocnemius.

Clinical differentiation of patients with mild diplegic cerebral palsy (CP) and idiopathic toe walking (ITW) can be difficult. However, an involuntary extensor pattern may be a distinguishing sign. The purpose of this study was to determine if selected gait parameters or patterns of electromyogram (EMG) timing of quadriceps, gastrocnemius, and tibialis anterior during knee extension while sitting can distinguish between these patients. The hypothesis was that EMG testing for selective control of the quadriceps and gastrocnemius could differentiate patients with diplegic CP from normal controls and from patients with ITW. We evaluated 10 control, eight CP, and eight ITW subjects. Measurements included walking speed, energy expenditure index (EEI), ankle position during stance, and EMG of the quadriceps, gastrocnemius, and tibialis anterior during gait and during knee extension while sitting. Dynamic EMG timing during gait showed significant differences in the mean onset of the gastrocnemius between subjects with CP and ITW, but there was considerable overlap. More consistent differences were found during active and active-resisted knee extension while sitting. Mean values for gastrocnemius EMG timing recorded as a percentage of duration of quadriceps EMG while sitting were 0 and 0.4% for controls, 0 and 3.9% for ITW subjects, and 84.3% and 93.4% for CP subjects. Patterns of EMG timing of the quadriceps and gastrocnemius during knee extension while sitting can help to differentiate patients with mild diplegic CP from those with ITW.

Erythrocyte deformability in survivors of acute myocardial infarction measured by two different methodologies.

In order to ascertain whether erythrocyte deformability (ED) is involved in chronic coronary syndromes, this rheological property was determined in 92 survivors of acute myocardial infarction (AMI) who had had the acute event 3 years ago and in 150 volunteers. From the 92 AMI survivors in 50 (43 males, 7 females aged 61+/-9 years) ED was determined with filtrometric techniques (Hanss Hemorheometre) and in 42 (32 males, 10 females aged 63+/-11 years) with laser diffractometric ones (Rheodyn SSD). The control group consisted of 66 and 84 volunteers whose ED was measured with the above mentioned devices respectively. Patients and controls were matched for age, sex, total cholesterol and triglyceride levels. With the Hanss Hemorheometre, the Rigidity Index (RI) was higher in patients than in controls (9.4+/-1.2 vs 8.7+/-1.5; p=0.01) although after adjusting for confounding variables (MCV and leukocyte count) in a logistic regression analysis the RI was no longer statistically significant. With the Rheodyn SSD the Erythrocyte Elongation Index (EEI) determined at 12, 30 and 60 Pa, did not show statistically significant differences between cases and controls at any of the shear stresses tested. Our results suggest that AMI survivors who had had the ischemic event 3 years ago do not show decrease RBC deformability with either of the two methodologies used. Red blood cell deformability does not appear to contribute to impaired microcirculatory blood flow in chronic coronary syndromes.

[Vaccination using an inactivated vaccine on a pig-breeding farm infected with the virus causing Aujeszky's disease (author's transl)].

When Aujeszky's disease was detected on a large pig-breeding farm, all normal sows and boars were vaccinated with an ethyl-ethylene-imine (EEI) vaccine produced in the Bundesforschungsanstalt für Viruskrankheiten der Tiere (Federal Research Institute for Viruses Diseases in Animals) in Tübbingen, Western Germany. The vaccine contained DEAE dextran as an adjuvant. The vaccine was inoculated twice by intramuscular route at a three weeks' interval, 5 ml. being inoculated at one time. Hyperimmune serum was inoculated in young pigs. In addition, hygienic procedures were adopted, consisting in disinfection and isolation. The disease was successfully controlled within eight weeks. Sows which developed Aujeszky's disease showed hardly any symptoms suggesting lesions of the central nervous system. Pulmonary lesions were the outstanding clinical feature. The semen quality of the affected male swine had markedly deteriorated. This was resorted to normal, however, within from five to ten weeks. The incidence of abortion and piglet mortality were low. In view of the results of virological and serological studies, it was concluded that the persistence of this strain of virus (causing Aujeszky's disease) was very slight.
