Glucocorticoid and thyroid hormones exert their effects in many body tissues by binding to their respective receptors. The search for possible cross-talking mechanisms in overlapping target cells led to the discovery of synergism between a thyroid hormone receptor-binding site and a cryptic glucocorticoid-responsive element. Glucocorticoid responsiveness could only be detected in the presence of thyroid hormone and its receptor. This synergism requires the glucocorticoid receptor (GR) DNA-binding domain and is mediated by the transactivation domains. We found that synergism also occurs when the thyroid hormone receptor is replaced by the retinoic acid receptor or the GR is replaced by the progesterone receptor. Synergism is qualitatively independent of the type of thyroid hormone receptor-binding site and promoter. In several combinations of promoter and response elements, including a retinoic acid response element, T3 induction was only seen in the presence of the cryptic glucocorticoid-responsive element, GR, and glucocorticoids.

To characterize ab and gd TcR expression in cultured TILs from a metastatic osteogenic sar- coma.Patient and methods: TILs were isolated from a lung metastasis of an osteogenic sarcoma in a 16- year-old female patient. Culture conditions were IL- 2 and anti-CD3 MoAb+IL-2. TcR expression and surface phenotype were studied by flow cytometry. 4h-chromium release assays were used to assess cytotoxicity. Results:IL-2-expanded tumor infiltrating T-lym- phocytes contained 50% gd TcR+ cells whereas gd TcR+ cells represented 20% of T-cells in cultures expanded with anti-CD3 MoAb+IL-2. The phenotype of gd TcR+ cells was CD3+, CD16-, CD4-, CD8-, and CD29+. AnH-CD3 MoAb + IL-2-expanded TILs mediated a significant lysis of thé autologous tumor and of an allogeneic lymphoma and displayed a higher activity against thé NK-sensitive target K562. In cold target experiments, unlabeled autol- ogous tumor cells blocked thé lysis of K562, indicating that MHC-unrestricted effectors were involved in thé lysis of both targets. Conclusions: This report demonstrates thé ex- pansion of large numbers of gd TcR+ T-cells after short-term culture of TILs from a metastatic os- teosarcoma. Further studies are needed to déter- mine thé role of gd TcR+ cells in host immune responses directed against this tumor. [less ▲]

We studied a patient who developed pure red cell aplasia (PRCA) following peripheral stem cell transplantation for non-Hodgkin lymphoma. Serum erythropoietin was appropriate for the degree of anemia. Corticosteroid treatment was ineffective. Four months after transplantation rHuEpo was administered subcutaneously at a dose of 150 U/Kg per day, five days a week for 8 weeks. Treatment induced an erythropoietic response and corrected anemia. Response was maintained following discontinuation of rHuEpo. This study and previous reports indicate that high doses of rHuEpo given over a short time can resolve PRCA following autologous or allogeneic stem cell transplantation. [less ▲]

Hemoblot, a new immunological faecal occult blood test, produced by Gamma, Angleur, Belgium, was characterized and compared with another immunological test (HemeSelect, SmithKline Diagnostics, USA) and with a guaiac test (Hemoccult II, SmithKline Diagnostics). The analytical sensitivity of Hemoblot is 0.15 mg haemoglobin/g faeces and the test is specific for human haemoglobin. In addition, 135 symptomatic patients who had to undergo a colonoscopy were tested using the three tests. Two criteria were considered for the analysis: (1) the blood criterion: any pathology likely to cause colorectal or other bleeding; and (2) the precancerous-cancerous criterion: the pathology being either a colorectal polyp > 0.5 cm or a colorectal cancer. Considering both criteria, the sensitivity of Hemoblot was significantly higher than the sensitivity of Hemoccult: 38% and 23%, respectively, for the blood criterion; and 54% and 29% for the precancerous-cancerous criterion. Sensitivity and specificity did not differ statistically between Hemoblot and HemeSelect but Hemoblot was faster and simpler to perform. It could be widely used in mass screening. [less ▲]

BACKGROUND: The authors tested the hypotheses that: (1) the vasoconstriction threshold during combined epidural/general anesthesia is less than that during general anesthesia alone; and (2) after vasoconstriction, core cooling rates during combined epidural/general anesthesia are greater than those during general anesthesia alone. Vasoconstriction thresholds and heat balance were evaluated under controlled circumstances in volunteers, whereas the clinical importance of intraoperative thermoregulatory vasoconstriction was evaluated in patients. METHODS: Five volunteers were each evaluated twice. On one of the randomly ordered days, epidural anesthesia (approximately T9 dermatomal level) was induced and maintained with 2-chloroprocaine. On both study days, general anesthesia was induced and maintained with isoflurane (0.7% end-tidal concentration), and core hypothermia was induced by surface cooling and continued for at least 1 h after fingertip vasoconstriction was observed. Patients undergoing colorectal surgery were randomly assigned to combined epidural/enflurane anesthesia (n = 13) or enflurane alone (n = 13). In appropriate patients, epidural anesthesia was maintained by an infusion of bupivacaine. The core temperature that triggered fingertip vasoconstriction identified the threshold. RESULTS: In the volunteers, the vasoconstriction threshold was 36.0 +/- 0.2 degrees C during isoflurane anesthesia alone, but significantly less, 35.1 +/- 0.7 degrees C, during combined epidural/isoflurane anesthesia. Cutaneous heat loss and the rates of core cooling were similar 30 min before vasoconstriction with and without epidural anesthesia. In the 30 min after vasoconstriction, heat loss decreased 33 +/- 13 W when the volunteers were given isoflurane alone, but only 8 +/- 16 W during combined epidural/isoflurane anesthesia. Similarly, the core cooling rates in the 30 min after vasoconstriction were significantly greater during combined epidural/isoflurane anesthesia (0.8 +/- 0.2 degrees C/h) than during isoflurane alone (0.2 +/- 0.1 degrees C/h). In the patients, end-tidal enflurane concentrations were slightly, but significantly, less in the patients given combined epidural/enflurane anesthesia (0.6 +/- 0.2% vs. 0.8 +/- 0.2%). Nonetheless, the vasoconstriction threshold was 34.5 +/- 0.6 degrees C in the epidural/enflurane group, which was significantly less than that in the other patients, 35.6 +/- 0.8 degrees C. When the study ended after 3 h of anesthesia, patients given combined epidural/enflurane anesthesia were 1.2 degrees C more hypothermic than those given general anesthesia alone. The rate of core cooling during the last hour of the study was 0.4 +/- 0.2 degrees C/h during combined epidural/enflurane anesthesia, but only 0.1 +/- 0.3 degrees C/h during enflurane alone. CONCLUSIONS: These data indicate that epidural anesthesia reduces the vasoconstriction threshold during general anesthesia. Furthermore, the markedly reduced rate of core cooling during general anesthesia alone illustrates the importance of leg vasoconstriction in maintaining core temperature. [less ▲]

The cyanobacterial genera Spirulina and Arthrospira are both characterized by helical trichomes but their taxonomy is controversial and a phylogenetic study is necessary. The sequence of the 16S rRNA gene and the spacer between the 16S and 23S rRNA genes (ITS) was determined for three filamentous coiled cyanobacteria: Spirulina PCC 6313, Arthrospira PCC 7345 and Arthrospira PCC 8005. A distance tree based on the 16S rRNA sequences was constructed using the neighbor-joining method. This tree shows that the two Arthrospira strains are not closely related to the Spirulina strain but belong to a cluster of strains assigned to the genera Oscillatoria, Lyngbya, and Microcoleus. The strain Spirulina PCC 6313 belongs to a branching containing unicellular cyanobacteria. For the two Arthrospira strains, the sequenced ITS region contains the tRNA(Ile) and tRNA(Ala) genes, whereas the spacer region of strain Spirulina PCC 6313 contains only the tRNA(Ile) gene.

The purpose of this study was to try to assess the fitness of endurance horses by using a simple routine standardized treadmill exercise test performed before and after a training period. Seven endurance horses aged 7 to 13 years, unfamiliar with the treadmill conditions and competing in international championship were tested twice in an air-conditioned laboratory, i.e. before and after a 4-month training period. The test was preceded by a 20 min warm-7 period and consisted of 2 min walk and 2 min trot (4.2 m/sec) with a slope of 0, 2, 4, 6, 8 and 10 The whole test lasted 45 min. Venous blood was sampled before and 4 min after each test. Heart rate was continuously recorded before, during and after the test with a cardiometer. Rectal temperature, respiratory rate and body weight were measured before and after the test. The completion of the test induced a significant decrease of the body weight, a significant increase in packed cell volume, cortisol, white blood cells, proportion of granulocytes, lactate, free fat acids and iso-enzyme LDH 5, and no change in the ions and in the activity of the other enzymes. Training did not induce significant changes in blood parameters, except in hacked cell volume and cortisol. Training induced a significant decrease in heart rate at all exercise intensities and during recovery. It was concluded that the test proposed in this study is simple, safe, suitable for horses unfamiliar with the treadmill and applicable in a 1-day clinic routine examination. In these conditions, the most reliable parameter for the assessment of fitness in endurance horses seems to be the heart rate recorded during 2 standardized tests performed before and after a training period [less ▲]

During an oceanographic cruise, carried out at the end of the austral summer (February-March 1991) in the Strait of Magellan, spatial patterns of size-fractionated chlorophyll and primary production were studied in relation to hydrographic patterns. Phytoplankton biomass, in terms of active Chl a, ranged between 10 and 51 mg m-2 and primary production between 275 and 1 170 mg C m-2 d-1. The most important features concern the confinement of the microphytoplanktonic fraction to the Pacific opening and to the embayements between the two Narrows. In the internal part of the Strait, an uniform dimensional structure (< 5 um) of phytoplankton communities was observed, with the picophytoplanktonic fraction always dominant. [less ▲]

PET studies have demonstrated bilateral temporo-parietal hypoperfusion and hypometabolism in probable and definite Alzheimer's disease (AD), a pattern that may help differentiate AD from other dementias. METHODS: To evaluate the diagnostic power of cerebral metabolic distribution patterns for "cortical" degenerative dementias, PET scans obtained from 129 patients referred for differential diagnosis of dementia were analyzed visually. RESULTS: Sixty-five patients had a final clinical diagnosis of probable AD. Ninety-seven percent (97%) of those had abnormal metabolic scans and 94% showed a suggestive pattern of bilateral or unilateral temporo-parietal hypometabolism (with or without frontal involvement). Hypometabolism was unilateral in 23% of patients. Five subjects with a neuropathologically proven diagnosis of Alzheimer's disease had a suggestive metabolic pattern. One of those was an early case with frontal hypometabolism exceeding temporo-parietal involvement. Two patients with Alzheimer's-type dementia had isolated bilateral frontal hypometabolism. CONCLUSIONS: This alternative metabolic pattern may correspond to a non-Alzheimer pathology occurring in 10%-20% of patients suffering from clinically probable Alzheimer's disease. Most of the patients with possible but atypical Alzheimer's-type dementia showed isolated bilateral frontal involvement. This metabolic pattern probably corresponds to different diseases, such as Pick's disease, frontal lobe dementia or progressive subcortical gliosis. [less ▲]

The problem of defining the physical concept of standardized visibility is addressed by means of a fuzzy logic approach. Assuming that several hypotheses hold, it is possible to evaluate a standardized visibility Vk (or meteorological visual range) as the ratio of a psychometric coefficient k and the extinction coefficient σ of the aerosol. The main disadvantage of this relationship due to Koschmieder stems from the fact that the meteorological visual range can be very different from visibility estimated by a human observer with normal sight. This is particularly true during fog extinction coefficient supplied by a transmissometer and the corresponding visibility evaluated by an expert. Calculations are performed according to two different approaches. First, a so-called fuzzy hyperbolic model based on a distance defined by Bardossy et al is presented, yielding a crisp (nonfuzzy) value of the coefficient k. Next, we use the multiplication of two fuzzy numbers, taken as triangular, to build an average fuzzy number k that accounts for the different values found in the literature. The defuzzification of k confirms the result obtained by the first approach. [less ▲]

This study investigated the effects of a drastic weight reduction on insulin secretion rate (ISR), insulin metabolic clearance rate (MCRI) and insulin sensitivity (SI) in severely obese subjects. A frequently sampled intravenous glucose tolerance test (FSIVGTT, 0.3 g/kg) was performed before and 8 +/- 1 months after a vertical ring gastroplasty in 12 overnight-fasted obese non-diabetic subjects; the results were compared to those obtained in 12 lean controls matched for age and sex. ISR was derived by deconvolution of plasma C-peptide levels; MCRI was obtained by dividing the area under the curve (AUC180 min) of ISR by the corresponding AUC of plasma insulin levels (IRI); the SI and the glucose effectiveness index (SG) were calculated by Bergman's minimal model. Before gastroplasty, obese subjects showed significantly higher ISR (P < 0.02), lower MCRI (P < 0.001), lower SI (P < 0.001) but similar SG when compared to lean controls. After gastroplasty (reduction of body weight from 104.8 +/- 3.8 to 73.4 +/- 3.6 kg and of BMI from 37.9 +/- 0.8 to 26.5 +/- 0.9 kg/m2; P < 0.001), ISR only decreased from 53,125 +/- 7968 to 42,302 +/- 3716 pmol/180 min (not significant) while AUC-IRI dramatically fell from 53,626 +/- 6378 to 21,111 +/- 2584 pmol.min/l; P < 0.001); consequently, MCRI markedly increased from 526 +/- 96 to 1257 +/- 150 ml/min/m2; P < 0.01). SI significantly rose from 3.12 +/- 0.45 to 7.10 +/- 1.20 x 10(-4) l/mU/min (P < 0.005) while SG remained unchanged.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Among the best characterized determinants are the cnr operon (resistance to Co, Ni) an pMOL28 and the czc operon on pMOL30 (resistance to Co, Cd and Zn). Although the two systems reveal a significant degree of amino acid similarity in the structural genes, the regulation of the operons is different. The resistance mechanism in both cases is based on efflux. The efflux mechanism leads to a pH increase outside of the cytoplasmic membrane. Metals are sequestered from the external medium through the bioprecipitation of metal carbonates formed in the saturated zone around the cell. This latter phenomenon can be exploited in bioreactors designed to remove metals from effluents. The bacteria are immobilized on composite membranes in a continuous tubular membrane reactor (CTMR). The effluent continuously circulates through the intertubular space, while the external surface of the tubes is in contact with the growth medium. Metal crystals are eventually removed by the effluent stream and collected on a glass bead column. The system has been applied to effluents containing Cd, Zn, Co, Ni and Cu. By introducing catabolic plasmids involved in the aerobic degradation of PCBs and 2,4-D into metal-resistant A. eutrophus strains, the application range was widened to include effluents polluted with both organic and inorganic substances. Biosensors have been developed which are based on the fusion of genes induced by metals to a reporter system, the lux operon of Vibrio fischeri. Bacterial luciferases produce light through the oxidation of fatty aldehydes. The gene fusions are useful both for the study of regulatory genes and for the determination of heavy metal concentrations in the environment. [less ▲]

A new method for calculating the anomalous transport in tokamak plasmas is presented. The renormalized nonlinear plasma response function is derived using the direct-interaction approximation (DIA). A complete calculation for the case of electrostatic drift-wave turbulence is presented. Explicit expressions for all coefficients of the anomalous transport matrix relating particle and heat fluxes to density and temperature gradients in the plasma are obtained. The anomalous transport matrix calculated using the DIA does not have the Onsager symmetry. As an example of application, the parameters of the Texas Experimental Tokamak (TEXT) [Nucl. Technol. Fusion 1, 479 (1981)] are used to evaluate all transport coefficients numerically, as well as the spectrum modulation. The relation between the theoretical results and the experimental data is discussed. Although this paper focuses on electron transport for simplicity, the method can also be used to calculate anomalous transport due to ion instabilities, such as the ion-temperature-gradient instability.

Peptides corresponding to lipid binding domains of Apo B-100 were synthesized, purified, and incubated with dimyristoylphosphatidylcholine (DMPC) liposomes. The secondary structure of the apo B-100 peptide-lipid complexes was evaluated by attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR). Those peptides belonging to the hydrophobic "core" domain of apo B-100 when associated with phospholipids were rich in beta sheet structure; a predominant alpha helical conformation was shown to be associated with one peptide located in a surface region of apo B-100. IR dichroic spectra revealed, in the case of the "core" peptides, that the beta sheet component is the only oriented structure with respect to the phospholipid acyl chains. This orientation of the beta sheet was recently found in LDL particles after proteolytic digestion by trypsin (Goormaghtigh, E., Cabiaux, V., De Meutter, J., Rosseneu, M., and Ruysschaert, J. M., 1993, Biochemistry 32, 6104-6110). Altogether, the data suggest that beta sheet, present in a high proportion in the native apo B-100, is probably another protein structure in addition to the amphipathic helix which strongly interacts with the lipid outer layer surrounding the LDL particle.

Two randomly distributed groups of thoroughbred horses were compared during a 12-week period for their cardio-respiratory and metabolic adjustment to strenuous exercise, training and detraining. The horses were trained following the same standardized schedule and were regularly investigated using standardized treadmill exercise tests (SET) of increasing speed. After the first SET and during the whole experimental period, a group of 6 horses received a probiotic (Bioracing) once a day while a group of 5 horses received a placebo. All other conditions were similar for both groups. During each SET, the oxygen uptake, carbon dioxide output, tidal volume (inspired volume), respiratory rate and expired minute volume were obtained using 2 ultrasonic pneumotachographs and a mass spectrometer. All the parameters were the mean of the values calculated during the last 20 s of the SET. Heart rate was continuously measured with a polar horse tester. Venous blood was sampled before and after the test and analyzed for various biochemical parameters. In both groups, training induced significant modification in most of the cardio-respiratory parameters, ie peak oxygen uptake, peak carbon dioxide output, respiratory exchange ratio, ventilation/min to oxygen-uptake ratio and oxygen-uptake to heart-rate ratio. After the 3-week detraining period, most of the values were again similar to the pre-training values in both groups. However, the training-induced modifications of most of the cardio-respiratory parameters occurred earlier and were proportionally greater in the probiotic-treated group than in the control. The respiratory coefficient decreased in the control but not in the treated group. All other parameters changed similarly in both groups. This suggests that Bioracing could modify the physiological effects of training by improving some aerobic metabolic capacities for carbohydrate utilization, but that this effect occurs only during training and not during periods of physical inactivity [less ▲]

A mutation causing muscular hypertrophy, with associated leanness and improved feed efficiency, has been recently identified in domestic sheep (Ovis aries). Preliminary results indicate that an autosomal dominant gene may be responsible for this economically advantageous trait. We have exploited the conservation in sequence and chromosomal location of DNA markers across Bovidae to map the corresponding callipyge locus to ovine chromosome 18 using a battery of bovine chromosome 21 markers. Chromosomal localization of the ovine callipyge locus is the first step toward positional cloning of the corresponding gene. [less ▲]

Circulation of the Western Mediterranean has been inferred from tracer properties and is the object of numerical modelling studies (eg., Beckers, 1991). The path of the Levantine Intermediate Water (LIW), thought o be a buoyancy forced flow, provides an indicator of mid-depth circulation (Millot, 1987b). However, modelling studies which include buoyancy forcing appear to misrepresent the flow of LIW. We have used the 'GFDL Modular Ocean Model' (MOM) to explore the suggestion of Holloway (1992) that subgridscale eddy-topography interaction may be responsible for such systematic defects. We have executed MOM with and without the parametrization of the eddytopography interaction. The different results are compared with circulation inferred from observational data. [less ▲]

Serpin reactive centre loops and fusion peptides released by proteolytic cleavage are particularly mobile. Their amino acid compositions reveal a common and unusual abundance of alanine, accompanied by high levels of glycine. These two small residues, which are not simultaneously abundant in stable helices (standard or transmembrane), probably play an important role in mobility. Threonine and valine (also relatively small amino acids) are also abundant in these two kinds of peptides. Moreover, the known 3D structures of an uncleaved serpin reactive centre and a fusion peptide are strikingly similar. Such sequences possess many small residues and are found in several signal peptides and in PrP, a protein associated with spongiform encephalopathies and resembling virus envelope proteins. These properties may be related to the infection mechanisms of these diseases. [less ▲]

The gelatinase A (72 kDa type IV collagenase) is a matrix metallo-proteinase which degrades basement membrane collagens. Various studies emphasize its role in stromal invasion of cancers, but there is some controversy about its origin. Gelatinase A was localized by immunohistochemistry using confocal microscopy in 15 human mammary carcinomas. In addition, the cells responsible for the synthesis of this enzyme were detected by in situ hybridization. Most invasive and non-invasive tumour cells were labelled by immunohistochemistry. Of particular interest was the pattern observed in some pre-invasive areas. Gelatinase A was found in fibroblasts in close contact with pre-invasive tumour clusters. Confocal observation allowed a more precise localization of gelatinase A to the periphery of tumour clusters along the basement membranes and in peritumour fibroblasts. The malignant epithelial cells were negative by immunohistochemistry in these areas. By in situ hybridization, mRNAs encoding gelatinase A were detected only in fibroblasts in close contact with pre-invasive and well differentiated tumour clusters. These findings support the hypothesis that peritumour fibroblasts produce gelatinase A and that breast cancer cells may bind this enzyme to their cell surface and/or internalize it. [less ▲]

In the framework of a research on the collisional mechanisms involved in tandem mass spectrometry, the collisional activation processes of NH3+ with different target gases have been investigated. The experiments have been performed on an upgraded AEI-MS9 sector instrument equipped with two collision cells and include daughter ion spectra, ion kinetic energy spectra, determination of kinetic energy release distributions (KERD) and appearance energy measurements. We have shown that collisionally activated dissociation (CAD) of NH3+ into NH++[H,H] depends upon the internal energy of NH3+. This internal energy effect is also observed for the NH2++H channel, when Xe is the target gas; with He, such an effect could not be detected. The analysis of the KERD shows that production of NH2+ upon CAD takes place from the NH3+ ground electronic state by rotational predissociation; two components are observed, one which corresponds to a near-threshold process (mean kinetic energy release <T>=0.13 eV), and one characterized by <T>=0.56 ev corresponding to an excess energy of 2.1 eV above the dissociation threshold. NH+ fragments can be formed by two processes: the first one occurs at threshold and leads to NH+(X2Pi)+H2(X1Sigma+g); the second one is characterized by large KER values (up to 7 eV) and leads to either electronically excited NH+ or dissociation of H2.

The thyroid hormone receptor (TR) and the retinoic acid receptor (RAR) induce gene expression in the presence of specific ligand and repress transcription in the absence of hormone. This repression is mediated by an active silencing mechanism rather then by interference with DNA binding activators. V-erbA, a variant form of TR which is unable to bind hormone, represents a constitutive repressor. Here we show, using fusion proteins with the GAL4 DNA binding domain, that the minimal silencing domain of v-erbA extends from amino acids 389 to 632 and that internal deletions within this domain retain at least some repression function. Co-transfection experiments of different deletion mutants indicate that the silencing domain is composed of at least two sub-domains which are non-functional when tested individually. When combined in a heterodimeric complex, they synergize such that silencing activity is regained. In contrast to the retinoic acid receptor the retinoid X receptor does not contain a silencing domain. In addition it is unable to cooperate with the repression function of TR or v-erbA in a heterodimer. [less ▲]

Male mice were tested for behavioral effects (BEs) of the dopamine (DA) agonist apomorphine (AP) at various times after acute administration of cocaine (COC). When most of the COC had disappeared from brain and the BEs of COC had dissipated (2 hrs and 4 hrs after administration), effects of AP on gnawing were increased 4-fold. This dopaminergic hypersensitivity (DA-H) was induced by acute treatment with doses of 15 mg/kg COC and higher. Effects of AP were not enhanced 6-24 hrs after COC, indicating a rapid waning of the DA-H. Hypersensitivity to AP (AP-H) was not further augmented by 8 days of daily COC injections. COC did not influence climbing and hypomotility induced by AP 4 hrs after its injection, demonstrating selectivity in the BEs of the DA-H. Further, COC did not induce sensitization to its own effects, indicating that the AP-H was not due to a typical sensitization phenomenon. ((c) 1997 APA/PsycINFO, all rights reserved) [less ▲]

This study has been conducted in order to define the guidelines of a permanent forest inventory methodology that could applied to heterogenous forests located in the southern part of Belgium. Different types of sampling units generally used in European national inventories have been compared: fixed area sampling units (based upon 3 concentric circles), non fixed-area sampling units (Bitterlich plots using basal area factor of 2 and 4) and sampling units based upon a minimum number of trees (including nearly 15 measurable trees). In true conditions of application 259 sampling points have been selected according to a systematic rectangular grid (1.000 m x 500 m). Taking into account different criteria such as precision, cost and ease of use, the fixed-area sampling unit looks like the most adequate among the four types investigated. [less ▲]

The monofrequency forced oscillation technique (MFOT) has been found to be a simple, reproducible, fast and accurate method to carry out lung function testing in calves even under field conditions. If some technical as well as methodological requirements are taken into account, pulmonary or respiratory resistance can be assessed by means of the parameter oscillatory resistance (Ros). Furthermore, several Ros derived parameters are available for describing the functional status of the central bronchial system. Due to the low variability caused by methodological or intraindividual reasons, the MFOT represents a very qualified method for intraindividual studies. Comparing measuring results of different subjects, a higher biologically caused variance has to be taken into account. [less ▲]

Electrophoretic mobility shift assays reveal that HeLa nuclear proteins bind fast and with measurable affinity to target DNAs containing mixed simple repetitive (gt)n(ga)m stretches. Preincubation of the proteins at elevated temperature prevents the formation of the major DNA/protein complex in favour of several distinct assemblies. A similar pattern of retarded bands was observed employing higher salt concentrations in the binding reaction. Thus conformational changes of different proteins appear to influence the complex rather than alternating DNA structures. Separation of the total nuclear extract into a water soluble and an insoluble protein fraction leads to a complete loss of target DNA binding capability of the fractions. The binding capacity is restored by combining the two fractions suggesting that at least two protein components are necessary to form a complex with the target sequence. The proteins can be differentiated into heat sensitive, water soluble and temperature stable, water insoluble, respectively. Furthermore, specifically binding polypeptides are not detectable by Southwestern analyses, probably because the essential components are separated during electrophoresis. DNase I footprint analyses yield four different protein binding regions only on the (gt)n(ga)m harbouring strand. The footprints cover larger portions of the mixed simple repeat in addition to a portion 5' of the (gt)n part. Hence at least two nuclear protein components of unknown biological function have to be present simultaneously to protect preferentially the (gt)n(ga)m-containing strand of intron 2 in HLA-DRB genes.

Cardiomyoplasty is a wrapping of an electrostimulated latissimus dorsi muscle flap around the heart for substitution and/or reinforcement. The surgical technique for reproducible cardiomyoplasties in the goat model is presented. The methods combine the direction of wrapping (clockwise, counter-clockwise) and the orientation of muscle fibers. A cardiomyoplasty model using right and left latissimus dorsi or left latissimus dorsi and pectoralis major as well as a split muscle technique are illustrated. [less ▲]

Extracts of wheat etioplast membranes obtained after treatment with 7 mM n-octyl-beta-D-glucopyranoside (OG), n-dodecyl-beta-D-maltoside (DM) or Triton X-100 contained the three spectral forms of Pchlide (the photoactive Pchlide(638) and Pchlide(638) and the inactive Pchlide(650)) in various relative amounds. The OG extract had a Pchlide composition close to that of the intact membranes whereas the DM extract was enriched in Pchlide(638) and the Triton extract was enriched in Pchlide(630). Measurements of the kinetics of phototransformation and of time-resolved absorbance spectra during phototransformation in continuous Light shows that the inactive Pchlide(630) is in fact slowly transformed to Chlide, especially in the Triton extract where this form is more abundant. Addition of NADPH favours the phototransformation of Pchlide(630) and the slow regeneration of Pchlide(638) and Pchlide(650) from Pchlide(630) in darkness after illumination. No such regeneration was however observed in the Triton extract. NADPH had only slight effects on the Chlide shift towards shorter wavelengths after phototransformation in solubilized membranes.

The transcriptional activity of the human placental lactogen genes (choriosomatomammotropic hormone, hCS) is controlled by tissue-specific enhancers located 4 kb downstream from their respective origins of transcription. The hCS-B enhancer is the strongest; its activity is mediated by synergism between two protein-binding sites (DF-3 and DF-4). The DF-4 site possesses a potential binding sequence for TEF-1, a known transcription factor. In this paper, we show by electrophoretic mobility-shift assays and antibody supershift experiments that TEF-1 does not bind to site DF-4. Mutations in the TEF-1-like binding motif of site DF-4 prevent formation of the DNA-protein complex, called complex f, in the presence of placental JEG-3 cell extracts. When HeLa cell extracts are used, another complex (complex c) is also affected. In transient expression experiments, TKCAT constructs linked to this mutated DF-4 site exhibit greatly reduced transcriptional activity when introduced into JEG-3 cells. Some cell lines contain both protein c and protein f (the proteins forming complexes c and f); when transfected, these lines display reduced DF-4-driven activity, suggesting that the two proteins could compete for the same DF-4 sequence. We conclude that protein f is important for the placenta-specific activity of the hCS-B enhancer. By UV cross-linking, we show that protein f is actually three polypeptides ranging in size from about 12 to 21 kD. [less ▲]
