| green fluorescent protein as a probe of rotational mobility within bacteriophage t4. | green fluorescent protein (gfp) was targeted into bacteriophage t4 heads and proheads as a probe of the internal environment. targeting was accomplished with internal protein iii (ipiii) fusion proteins or capsid targeting sequence (cts)-tagged proteins, where cts is the 10-amino acid residue cts of ipiii. recombinant phage t4[cts/ipiii/gfp], t4[cts/ipiii(t)gfp], and t4[cts/gfp] packaged gfp fusion proteins and processed them at cleavage sites designated /. steady-state and time-resolved fluores ... | 2000 | 10921840 |
| sympathetic innervation alters activation of pacemaker current (if) in rat ventricle. | pacemaker current (if) exists in both neonatal and adult ventricles, but activates at more negative voltages in the adult. this study uses whole-cell patch clamp to investigate the factors that may contribute to the maturational shift of if, comparing neonatal rat ventricular myocytes that were cultured for 4-6 days either alone, in co-culture with sympathetic nerves, or with neurotransmitters chronically present in culture. if recorded from nerve-muscle co-cultures had a significantly more nega ... | 2000 | 10922008 |
| establishment of introduced antagonistic bacteria in the rhizosphere of transgenic potatoes and their effect on the bacterial community. | in a field release experiment, rifampicin resistant mutants of two antagonistic plant-associated bacteria were used for seed tuber inoculation of transgenic t4 lysozyme expressing potatoes, transgenic control potatoes and non-transgenic parental potatoes. the t4 lysozyme tolerant pseudomonas putida qc14-3-8 was originally isolated from the tuber surface (geocaulosphere) of t4 lysozyme producing plants and showed in vitro antibacterial activity to the bacterial pathogen erwinia carotovora ssp. at ... | 2000 | 10922502 |
| double-strand break repair in tandem repeats during bacteriophage t4 infection. | recombinational repair of double-strand breaks in tandemly repeated sequences often results in the loss of one or more copies of the repeat. the single-strand annealing (ssa) model for repair has been proposed to account for this nonconservative recombination. in this study we present a plasmid-based physical assay that measures ssa during bacteriophage t4 infection and apply this assay to the genetic analysis of break repair. ssa occurs readily in broken plasmid dna and is independent of the st ... | 2000 | 10924452 |
| dinucleotide repeat expansion catalyzed by bacteriophage t4 dna polymerase in vitro. | dna replication normally occurs with high fidelity, but certain "slippery" regions of dna with tracts of mono-, di-, and trinucleotide repeats are frequently mutation hot spots. we have developed an in vitro assay to study the mechanism of dinucleotide repeat expansion. the primer-template resembles a base excision repair substrate with a single nucleotide gap centered opposite a tract of nine ca repeats; nonrepeat sequences flank the dinucleotide repeats. dna polymerases are expected to repair ... | 2000 | 10924513 |
| cortical representation of pain: functional characterization of nociceptive areas near the lateral sulcus. | many lines of evidence implicate the somatosensory areas near the lateral sulcus (sylvian fissure) in the cortical representation of pain. anatomical tracing studies in the monkey show nociceptive projection pathways to the vicinity of the secondary somatosensory cortex in the parietal operculum, and to anterior parts of insular cortex deep inside the sylvian fissure. clinical observations demonstrate alterations in pain sensation following lesions in these two areas in human parasylvian cortex. ... | 2000 | 10924804 |
| does the combination of radiotherapy and debulking surgery favor survival in paranasal sinus carcinoma? | to determine the contribution of debulking surgery on local control and survival in paranasal sinus tumors. as most patients present with locally advanced disease, the possibility of radical surgery is limited. consequently, radiotherapy is often needed as monotherapy or as an adjunct to surgery. | 2000 | 10924968 |
| subclinical thyroid disease after radiation therapy detected by radionuclide scanning. | the actuarial risk for developing benign or malignant thyroid disease following radiation therapy (rt) is controversial, but may be as high as 50% at 20 years. an effective screening modality should be specific but not overly sensitive, a limitation of ultrasound. we questioned whether technetium-99 m pertechnetate ((99m)tc tco(4)(-)) scanning could detect clinically significant disease in ostensibly disease-free cancer survivors. | 2000 | 10924988 |
| importance of gluten in the induction of endocrine autoantibodies and organ dysfunction in adolescent celiac patients. | it is well known that a high number of celiac patients may develop autoantibodies against endocrine glands, but it has not yet been clarified if this increased autoimmune response and the impaired organ function that can develop may be related to the presence or absence of gluten in the diet. the aim of the present study was to evaluate the effect of gluten on the autoimmunity and function of the endocrine glands in adolescent celiac patients. | 2000 | 10925978 |
| effects of pneumoperitoneum and reverse trendelenburg position on cardiopulmonary function in morbidly obese patients receiving laparoscopic gastric banding. | we prospectively evaluated the effects of pneumoperitoneum and reverse trendelenburg position on cardiopulmonary function in 20 asa physical status ii-iii morbidly obese patients (body mass index > 35 kg m(-2)) undergoing laparoscopic gastric banding. after general anaesthesia was induced, patients' lungs were ventilated using intermittent positive pressure ventilation (at measurement times, the following parameters were used: tidal volume 12 ml kg(-1) ideal body weight, respiratory rate of 12 b ... | 2000 | 10926070 |
| function of tyrosyl-trna synthetase in splicing group i introns: an induced-fit model for binding to the p4-p6 domain based on analysis of mutations at the junction of the p4-p6 stacked helices. | we used an escherichia coli genetic assay based on the phage t4 td intron to test the ability of the neurospora crassa mitochondrial tyrosyl-trna synthetase (cyt-18 protein) to suppress mutations that cause structural defects around its binding site in the p4-p6 domain of the group i intron catalytic core. we analyzed all possible combinations of nucleotides at either p4 bp-1 or p6 bp-1, which together form the junction of the p4-p6 stacked helices, and looked for synergistic effects in double m ... | 2000 | 10926509 |
| hormonal regulation of glutathione s-transferase expression in co-cultured adult rat hepatocytes. | glutathione s-transferases (gsts) are subject to regulation by thyroid and sex hormones and by gh. we have used an in vitro experimental system comprising adult rat hepatocytes co-cultured with rat liver epithelial cells of primitive biliary origin, to distinguish between direct and indirect effects of various hormones on gsts; to identify the gst subunits affected by individual hormones; and to investigate the level at which the hormones act. tri-iodothyronine (t3), thyroxine (t4) and 17beta-oe ... | 2000 | 10927625 |
| atrial resection in advanced lung carcinoma under total cardiopulmonary bypass. | there are few reports of a surgical approach to t4 lung carcinoma that has invaded the heart. although most cases will be considered inoperable, cases in which there is potential for complete resection and no distant or nodal metastatic disease (t4 n0 m0, stage iiib) may be considered for surgical therapy. we report a case of squamous cell carcinoma of the lung with cardiac involvement, in which we performed a completion pneumonectomy using total cardiopulmonary bypass. we describe indications a ... | 2000 | 10928496 |
| thyroxine modulates corticotropin-releasing factor but not arginine vasopressin gene expression in the hypothalamic paraventricular nucleus of the developing rat. | neonatal rats were daily injected with 100 microg/kg t4 and killed at 4, 8 or 15 days. circulating corticosterone and corticosteroid binding globulin concentrations increased in 8- and 15-day-old rats after t4 treatment. plasma adrenocorticotropic hormone (acth) concentrations, pituitary acth content and pro-opiomelanocortin mrna expression were unaffected in t4-treated rats. t4 treatment induced an increase in corticotropin-releasing factor (crf) mrna expression in the whole population of crf s ... | 2000 | 10929090 |
| reduced muscle vascular resistance in intrauterine growth restricted newborn piglets. | it has been shown that asymmetrical intrauterine growth restriction is denoted by disproportional reduction of muscle mass compared to body weight reduction. however, the effects of iugr on regional vascular resistance and blood flow of skeletal muscles and their contractile function have not been studied until now. therefore, muscle blood flow (mbf) and isometric force output of serial stimulated hindlimb plantar flexors was measured in thiopental -anesthetized normal weight (nw; n = 9) and int ... | 2000 | 10930129 |

| thyroid function in wholly breast-feeding infants whose mothers take high doses of propylthiouracil. | propylthiouracil (ptu) might theoretically be preferred over methimazole (mmi) during breast-feeding because of its lower milk/serum concentration ratio (0.1 vs. 1.0). the problem is that graves' disease often relapses during the postpartum period, and high doses of ptu are sometimes needed to control maternal hyperthyroidism) during breast-feeding. however, there are virtually no data on the effects of maternal ptu on thyroid status of infants whose mothers take more than 300 mg ptu daily and w ... | 2000 | 10931098 |
| changes in serum thyroid hormones levels and their mechanisms during long-term growth hormone (gh) replacement therapy in gh deficient children. | the effects of gh therapy on thyroid function among previous reports have shown remarkable discrepancies, probably due to differences in hormone assay methods, degree of purification of former pituitary-derived gh preparations, dosage schedules, diagnostic criteria, patient selection, duration of treatment and study design. these considerations motivated us to investigate whether and how gh replacement therapy changes serum thyroid hormone levels, including the much less studied rt3 levels, in a ... | 2000 | 10931099 |
