| reciprocal interactions between beta1-integrin and epidermal growth factor receptor in three-dimensional basement membrane breast cultures: a different perspective in epithelial biology. | anchorage and growth factor independence are cardinal features of the transformed phenotype. although it is logical that the two pathways must be coregulated in normal tissues to maintain homeostasis, this has not been demonstrated directly. we showed previously that down-modulation of beta1-integrin signaling reverted the malignant behavior of a human breast tumor cell line (t4-2) derived from phenotypically normal cells (hmt-3522) and led to growth arrest in a three-dimensional (3d) basement m ... | 1998 | 9843973 |
| bacteriophage t4 initiates bidirectional dna replication through a two-step process. | two-dimensional gel analysis of the bacteriophage t4 ori(uvsy) region revealed a novel "comet" on the y arc. this comet contains simple y molecules in which the branch points map to the ori(uvsy) transcript region. the comet depends on the the origin and dna synthesis and is abolished by a mutation that reduces replication without affecting transcription. these results argue that the branched molecules are intermediates in replication initiation. a transcriptional terminator, cloned just downstr ... | 1998 | 9844641 |
| continuous hyperfractionated accelerated radiotherapy with/without mitomycin c in head and neck cancer. | to evaluate the effect of mitomycin c to an accelerated hyperfractionated radiation therapy. the aim was to test a very short schedule with/without mitomycin c (mmc) with conventional fractionation in histologically verified squamous cell carcinoma of the head and neck region. | 1998 | 9845100 |

| [ability of erythrocytes to deposit thyroid hormones: regulatory role of physico-chemical factors in vitro]. | data obtained suggest the existence of regulation mechanism controlling parameters of thyroid status, that does not require any modification of thyroid gland secretory function. the realisation of this mechanism can involve hormone-depositing function of blood erythrocytes, which is sensitive to a) change of regional or systemic ph and b) change of hematocrit. results of the present study indicate that mammalian erythrocytes are able to bind considerable quantities of t3 and t4 and, t3 binding i ... | 1998 | 9845926 |

| continuous hyperfractionated accelerated radiotherapy in advanced head and neck malignancies. | 58 patients of advanced head and neck cancer were treated by continuous hyperfractionated accelerated radiotherapy (study group) or conventional radiotherapy (control group). the study group of 29 patients had 26/29 (89%) of patients of stage t3 and t4 with 12/29 (41% 0) > n2 disease. the schedule employed was 1.5 gy 3 times a day in 36 fractions on 12 treatment days without stopping for weekends. the spinal dose has been kept at 40.5 gy and interfraction interval has been strictly kept at 6 hrs ... | 1998 | 9847466 |
| thyroxine replacement attenuates hypothyroxinemia, hearing loss, and motor deficits following developmental exposure to aroclor 1254 in rats. | the nervous system is dependent upon thyroid hormones for normal development, and we previously reported that developmental aroclor 1254 (a1254) exposure caused hypothyroxinemia, hearing loss and other behavioral changes in rats. (goldey et al., 1995a; herr et al., 1996). the hypothesis that a1254-induced hypothyroxinemia may have contributed to the observed functional changes was tested in primiparous long-evans rats given daily oral doses of corn oil (control) or 8 mg/kg of aroclor 1254 from g ... | 1998 | 9848116 |
| pelvic exenteration for advanced primary rectal cancer in male patients. | between november 1987 and january 1996 pelvic exenteration for primary rectal cancer was carried out in 11 male patients. two underwent a primary resection with subtotal cystectomy. in the remaining nine patients, the treatment commenced with a staging laparotomy and the fashioning of an end colostomy of the descending colon, followed by preoperative radiotherapy (50-56 gy in 5 weeks). total exenteration with uretero-ileo-cutaneostomy was carried out 4-6 weeks later. in two patients, the exenter ... | 1998 | 9848333 |

| neomycin b inhibits splicing of the td intron indirectly by interfering with translation and enhances missplicing in vivo. | the aminoglycoside antibiotic neomycin b inhibits translation in prokaryotes and interferes with rna-protein interactions in hiv both in vivo and in vitro. hitherto, inhibition of ribozyme catalysis has only been observed in vitro. we therefore monitored the activity of neomycin b and several other aminoglycoside antibiotics on splicing of the t4 phage thymidylate synthase (td) intron in vivo. all antibiotics tested inhibited splicing, even chloramphenicol, which does not inhibit splicing in vit ... | 1998 | 9848660 |
| the neuropeptides, vip and npy, that are present in the thyroid nerves are not released into the thyroid vein. | in the present study, we tested the hypothesis that the neuropeptides, vasoactive intestinal peptide (vip) and neuropeptide y (npy), which are present in the thyroid nerves, act as physiological neurotransmitters involved in the regulation of thyroid hormone secretion and thyroid blood flow. specifically, we examined whether these neuropeptides can be released into thyroid blood vessels by electrical stimulation of the major thyroid nerves or whether their expression is altered by changes in iod ... | 1998 | 9848726 |
| thyroxine administration to infants of less than 30 weeks gestational age decreases plasma tri-iodothyronine concentrations. | to investigate the effect on thyroid hormone metabolism of the administration of thyroxine to very preterm infants. | 1998 | 9849815 |
| decrease in plasma levels of vasoactive intestinal polypeptide in short bowel syndrome: experimental study. | to investigate the behaviour of the vasoactive intestinal polypeptide (vip) in short bowel syndrome (sbs), an experimental model of massive intestinal resection (mir) was developed. for this purpose, 20 'minipigs' were divided into two experimental groups: a (control) and b (mir). the parameters determined were the mean plasma levels of vip and the degree of steatorrhea at four different times: t1 (basal), t2 (one week after surgery), t3 (two weeks after surgery), and t4 (24 weeks after surgery) ... | 1998 | 9851334 |
| the prediction of the prognosis for rectal carcinoma down-staged by pre-operative radiotherapy by transrectal ultrasonography. | we attempted to determine whether the results of transrectal ultrasonography (trus) could provide any prognostic information about patients with rectal carcinoma treated with pre-operative radiotherapy (rt). | 1998 | 9851337 |
| molecular diagnosis of residual and recurrent thyroid cancer by amplification of thyroglobulin messenger ribonucleic acid in peripheral blood. | serum thyroglobulin measurement by immunoassay is used to detect residual or recurrent thyroid cancer after thyroid ablation. however, the usefulness of immunoassay is limited by both the requirement for thyroid hormone withdrawal to attain optimal test sensitivity and interference by antithyroglobulin antibodies. to circumvent these problems, we amplified thyroglobulin messenger ribonucleic acid (mrna) in peripheral blood using rt-pcr and compared the accuracy of this test to serum thyroglobuli ... | 1998 | 9851791 |
| abortive initiation of transcription at a hybrid promoter. an analysis of the sliding clamp activator of bacteriophage t4 late transcription, and a comparison of the sigma70 and t4 gp55 promoter recognition proteins. | bacteriophage t4 late promoters are transcribed by an rna polymerase holoenzyme comprising the escherichia coli core, e, the phage gene 55-encoded promoter recognition subunit, gp55, and the gene 33-encoded co-activator, gp33. transcriptional initiation is activated by the t4 gene 45-encoded sliding clamp, which is loaded on to dna at enhancer-like sites by its clamp-loader. correct initiation of transcription at late promoters in basal mode requires only rna polymerase core and gp55 (e.gp55). d ... | 1998 | 9852060 |
| substrate mutations that bypass a specific cpn10 chaperonin requirement for protein folding. | the bacteriophage t4 groes homologue, gp31, in conjunction with the escherichia coli chaperonin groel, is both necessary and sufficient to fold the t4 major capsid protein, gp23, to a state competent for capsid assembly as shown by in vivo expression studies. groes is unable to function in this role as a productive co-chaperonin. the sequencing and characterization of mutations within gp23 that confer groel and gp31 chaperonin-independent folding of the mutant protein suggest that the chaperonin ... | 1998 | 9852065 |
| correlation of activated monocytes or b cells with t lymphocyte subsets in patients with graves' disease. | we analyzed the phenotypic characteristics of pbmc from 34 patients with graves' disease (gd) at different stages of the disease to explore the sequence of immunological events associated with it. in all cases their monocytes were in a state of activation and differentiation more advanced than those of a group of 23 healthy individuals. strikingly, some patients had cd14++dr- immature monocytes, which were absent in healthy individuals. cd14+cd16+drhigh monocytes were more abundant in patients. ... | 1998 | 9852205 |
| metachronous cancer: prognostic factors including prior irradiation. | in this article we evaluate two factors that may be responsible for the reported increased mortality rate in metachronous cancers: prior radiation therapy and stage at presentation. a select group of 358 patients was split into three groups: no prior cancer (group 1), prior cancer treated with radiation therapy (group 2), and prior cancer treated with surgery alone (group 3). we compared survival among the three groups according to stage (t1 or t2 vs. t3 or t4) using the lifetest procedure. surv ... | 1998 | 9852536 |
| segmental specificity of chick sympathetic preganglionic projections is influenced by preganglionic neurons from neighboring spinal cord segments. | sympathetic preganglionic neurons of the chick are located between the brachial and lumbosacral enlargements of the spinal cord. their axons exit the spinal cord via their adjacent ventral roots and project rostrally or caudally along the sympathetic trunk to innervate sympathetic ganglia. the projections of sympathetic preganglionic neurons are segmentally specific. neurons from the 16th cervical (c16) and the first thoracic (t1) spinal cord segments project predominantly in the rostral directi ... | 1998 | 9852585 |
| effects of postprandial hyperlipemia on the vitamin e content of lipoproteins. gerbap section lipoprotéines. groupe d'evaluation et de recherche de l'assistance publique des hôpitaux de paris. | delayed postprandial clearance of triglyceride-rich lipoproteins (tgrl) could induce a decrease of low-density lipoprotein (ldl) and high-density lipoprotein (hdl) vitamin e content through its transfer into tgrl. we thus studied lipoprotein vitamin e content during postprandial hypertriglyceridemia induced by a high fat meal without vitamin e supplement. venous blood was drawn from five healthy male volunteers following a 12 h fast at (t0) then 2 h (t2), 4 h (t4), 6 h (t6) and 8 h (t8) after a ... | 1998 | 9853697 |
| hypoplastic anaemia complicating myxoedema coma. | the case of a 68 year old women presenting in myxoedema coma is described. she was found to be anaemic with a haemoglobin of 8.2 g/dl. further investigations showed a pancytopenia and a hypoplastic anaemia confirmed by bone marrow. the patient recovered and became euthyroid following initial treatment with intravenous tri-iodothyronine (t3) and later oral thyroxine (t4) replacement with resolution of pancytopenia and return of bone marrow to normal. | 1998 | 9854303 |
