### Instruction: Does fluid accumulation within the uterine cavity reduce pregnancy rates in women undergoing IVF? ### Response:
Fluid accumulation within the uterine cavity during the IVF transfer treatment could be observed in patients with both tubal and non-tubal factors; however, it mainly occurred in women with tubal infertility. Although it is not a common complication of IVF cycles, excessive uterine fluid is detrimental to embryo implan...
### Instruction: Does paclitaxel trigger cell death primarily via caspase-independent routes in the non-small cell lung cancer cell line NCI-H460? ### Response:
Paclitaxel triggers cell death in H460 cells mainly via a currently unidentified caspase-independent mechanism in which the basic apoptotic machinery is merely coactivated. This finding is in sharp contrast with the largely caspase-dependent response elicited by DNA-damaging agents in these cells. We speculate on thera...
### Instruction: Are substance P and neurokinin levels decreased in the cortex and hypothalamus of alcohol-preferring ( P ) rats? ### Response:
These data indicate that endogenous SP and neurokinin levels are reduced in discrete brain regions of P rats compared with NP rats. These decreases may be associated with decreased serotonergic innervation of these brain regions in P rats compared with NP rats.
### Instruction: Does clomipramine increase the striatal concentrations of dopamine and homovanillic acid in rats chronically consuming alcohol? ### Response:
These findings show that clomipramine produces favorable changes in dopaminergic systems altered by chronic alcohol administration. Results also provide evidence to support further prospective studies of potential therapeutic effects of antidepressant drugs in alcoholism.

### Instruction: Is inhibition of factor IX ( a ) protective in a rat model of thromboembolic stroke? ### Response:
The data indicate that the inhibition of factor IX(a) within 4 hours of thromboembolic stroke produced a more favorable outcome than tPA. When treatment was initiated 6 hours after stroke, the benefits of factor IX(a) inhibition were lost, whereas tPA continued to suppress lesion development, albeit without a correspon...
### Instruction: Do selectins mediate macrophage infiltration in obstructive nephropathy in newborn mice? ### Response:
Following UUO, selectins mediate macrophage infiltration into the obstructed kidney, which in turn may induce tubular apoptosis, tubular atrophy and interstitial fibrosis.
### Instruction: Does indomethacin protect permeability barrier from focal segmental glomerulosclerosis serum? ### Response:
These studies implicate a product of the cyclooxygenase pathway of arachidonic acid metabolism as mediating the increased Palb caused by FSGS serum in our in vitro assay and possibly the proteinuria seen in patients with FSGS.
### Instruction: Do effects of oxalate on the re-initiation of DNA synthesis in LLC-PK1 cells involve p42/44 MAP kinase activation? ### Response:
These findings demonstrate that oxalate does not activate the p42/44 MAP kinase pathway, and the effects of oxalate are mediated by pathways that are distinct from those of EGF, PDGF and insulin.
### Instruction: Is the abdominal compartment syndrome a morbid complication of postinjury damage control surgery? ### Response:
ACS after postinjury DCS worsens outcome. With the exception of early elevation in peak airway pressure, we could not identify patients at higher risk for ACS; moreover, preemptive abdominal bag closure during initial DCS did not prevent this highly morbid complication.
### Instruction: Does tumor hypoxia have independent predictor impact only in patients with node-negative cervix cancer? ### Response:
Tumor hypoxia is an independent predictor of poor PFS only in patients with node-negative cervix cancer, in addition to tumor size. Its impact appears to be related to an increased risk of distant metastases rather than to an effect on pelvic control.
### Instruction: Does [ Request of dental care and periodontal treatment need in a population sample of Palermo ]? ### Response:
These findings showed that the awareness of periodontal diseases by the population examined is poor. This could be due either to the lack or failure of public education programmes on periodontal health. Yet, it could be related to an inadequate dentists' awareness of the periodontal diseases. Such findings should be co...
### Instruction: Does notch signaling control cell fate specification along the dorsoventral axis of the Drosophila gut? ### Response:
Our results demonstrate that Notch signaling plays a pivotal role in determining cell fates along the DV axis of the Drosophila hindgut. The finding that Notch signaling results in the expression of an apical polarity organizer which may be required, in turn, for apical Notch receptor localization suggests a simple mec...
### Instruction: Does contactin support synaptic plasticity associated with hippocampal long-term depression but not potentiation? ### Response:
These results indicate that contactin plays a selective role in synaptic plasticity and identify PPF and LTD, but not LTP, as contactin-dependent processes. Engagement of the contactin-Caspr complex with RPTPbeta may thus regulate cell-cell interactions contributing to specific synaptic plasticity forms.
### Instruction: Do [ Nonperforating trabecular surgery with reticulated hyaluronic acid implant ]? ### Response:
The elevated IOP in patients with open angle glaucoma can be effectively reduced by NPTS, and the number of drugs used for anti-glaucoma was decreased.

### Instruction: Do mucin and phospholipids determine viscosity of gallbladder bile in patients with gallstones? ### Response:
The viscosity of gallbladder bile is markedly higher than that of hepatic bile in patients with gallstones. The concentration of mucin is the major determinant of biliary viscosity and may contribute by this mechanism to the role of mucin in the pathogenesis of gallstones.
### Instruction: Does rotational atherectomy reduce recurrent in-stent restenosis : results of the angioplasty versus rotational atherectomy for treatment of diffuse in-stent restenosis trial ( ARTIST )? ### Response:
In terms of the primary objective of the study, PTCA produced a significantly better long-term outcome than ROTA followed by adjunctive low-pressure PTCA.
### Instruction: Does angiotensin II type 1 receptor blockade ameliorate tubulointerstitial injury induced by chronic potassium deficiency? ### Response:
These results indicate that hypokalemic renal injury is mediated, at least in part, by Ang II via the Ang II type 1 receptor, with a lesser contribution mediated by a reduction in nitric oxide. Losartan may be beneficial in preventing hypokalemic tubulointerstitial injury.
### Instruction: Does pyridoxamine inhibit early renal disease and dyslipidemia in the streptozotocin-diabetic rat? ### Response:
Pyridoxamine inhibits the progression of renal disease, and decreases hyperlipidemia and apparent redox imbalances in diabetic rats. Pyridoxamine and aminoguanidine had similar effects on parameters measured, supporting a mechanism of action involving AGE/ALE inhibition.
### Instruction: Is transthoracic echocardiography cost-effective in critically ill surgical patients? ### Response:
The routine use of TTE to initially evaluate all critically ill surgical patients who require echocardiography should be abandoned because it is not cost-effective. TEE appears to be the most cost-effective echocardiographic modality in the surgical intensive care unit.
### Instruction: Is the sensitivity of digestive tract tumor cells to As2O3 associated with the inherent cellular level of reactive oxygen species? ### Response:
The cellular sensitivity to apoptosis induced by As2O3 is associated with the difference in cellular ROS level. The inherent ROS level might determinate the apoptotic sensitivity of tumor cells to As2O3.
### Instruction: Does rRR-alpha-tocopheryl succinate inhibit human gastric cancer SGC-7901 cell growth by inducing apoptosis and DNA synthesis arrest? ### Response:
VES can inhibit human gastric cancer SGC-7901 cell growth by inducing apoptosis and DNA synthesis arrest. Inhibition of SGC-7901 cell growth by VES is dose- and time-dependent. Therefore VES can function as a potent chemotherapeutic agent against human gastric carcinogenesis.
### Instruction: Does vEGF165 antisense RNA suppress oncogenic properties of human esophageal squamous cell carcinoma? ### Response:
The angiogenesis and tumorigenicity of human esophageal squamous cell carcinoma were effectively inhibited by VEGF165 antisense RNA. Antisense RNA to VEGF165 can potentially be used as an adjuvant therapy for solid tumors.

### Instruction: Is gastric permeability increased in children colonized by CagA-positive strains of Helicobacter pylori? ### Response:
These results indicate that in Chile, about 60% of the Helicobacter pylori infected children are colonized by CagA-positive strains, in association with more intense lesions of the gastric mucosa, but that gastric permeability to sucrose does not discriminate between colonization by CagA-negative and positive strains o...
### Instruction: Are relatively high risk of treatment failure after prostatectomy : tumour grade , histopathological stage and the preoperative serum PSA level key prognosticators? ### Response:
Our study indicates, that the risk of treatment failure depends strongly on the grade of the tumour and increases when preoperative PSA value is greater than l0 ng/ml.
### Instruction: Does tolbutamide alter glucose transport and metabolism in the embryonic mouse heart? ### Response:
Tolbutamide stimulates glucose uptake and metabolism in the embryonic heart, as occurs in adult extra-pancreatic tissues. Glut-1 and HKI, but not GRP78, are likely involved in tolbutamide-induced cardiac dysmorphogenesis.
### Instruction: Is thyroid transcription factor-1 highly sensitive and specific in differentiating metastatic pulmonary from extrapulmonary adenocarcinoma in effusion fluid cytology specimens? ### Response:
The current study validates TTF-1 as a highly sensitive and specific immunomarker for distinguishing between metastatic pulmonary and extrapulmonary adenocarcinoma in effusion cytology specimens, which are known to be associated with intrinsic artifact due to less than ideal cellular preservation.
### Instruction: Is cortisol-binding globulin important in the interpretation of dynamic tests of the hypothalamic -- pituitary -- adrenal axis? ### Response:
CBG varies significantly within and between individuals. This is accompanied by changes in serum total cortisol large enough to affect the outcome of an SST and, by implication, other tests of the HPA axis.
### Instruction: Does postnatal endotoxin exposure result in increased insulin sensitivity and altered activity of neuroendocrine axes in adult female rats? ### Response:
The results indicate that postnatal exposure to LPS leads to increased insulin sensitivity in the adult female rat. In addition, LPS-treated rats showed changes in the regulation of hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes. This study suggests that postnatal exposure to an endotoxin such a...
### Instruction: Does impairment of vascular regeneration precede progressive glomerulosclerosis in anti-Thy 1 glomerulonephritis? ### Response:
Progressive glomerulosclerosis can be induced in the rat by a one shot injection of anti-Thy 1.1 monoclonal antibody followed by unilateral nephrectomy. This model shows that there is a positive association between impairment of vascular regeneration and the development of glomerulosclerosis.
### Instruction: Does addition of AT1 blocker fail to overcome resistance to ACE inhibition in adriamycin nephrosis? ### Response:
ACE inhibition has variable renal protective efficacy in the adriamycin model. Neither increasing the dose of the ACE inhibitor beyond the optimal level nor co-treatment with AII-A overcome the individual therapy resistance. Thus, in established adriamycin nephrosis, blockade of the renin-angiotensin system at two diff...
### Instruction: Do human renal epithelial cells express iNOS in response to cytokines but not bacteria? ### Response:
We conclude that uropathogenic E. coli that attach to HRTEC fail to directly activate iNOS expression, and that iNOS expression during bacterial infection is more likely to result from stimulation by local cytokines such as IL-1beta and IFN-gamma.
### Instruction: Do reported adverse food reactions overestimate true food allergy in the community? ### Response:
There was little agreement between self-reported perceived illness to food(s) known to contain the food allergen of interest, and positive SPT, suggesting that most reactions are not due to IgE mediated food allergy.

### Instruction: Does early postoperative enteral feeding increase anastomotic strength in a peritonitis model? ### Response:
These data suggest that immediate postoperative feeding results in a beneficial change in the cytokine profile.
### Instruction: Does vagal stimulation rapidly increase leptin secretion in human stomach? ### Response:
Vagal stimulation of leptin release in the human stomach suggests that leptin is released during the cephalic phase of gastric secretion. Luminal leptin may be involved in vagus-mediated intestinal functions.
### Instruction: Does acid exposure activate the mitogen-activated protein kinase pathways in Barrett 's esophagus? ### Response:
Acid increases proliferation and survival, and decreases apoptosis in SEG-1 cells by activating the MAPK pathways. Acid also activates the MAPK pathways in BE in vivo. These findings suggest that acid might contribute to carcinogenesis in BE through activation of MAPK pathways.
### Instruction: Do opioid agonists inhibit excitatory neurotransmission in ganglia and at the neuromuscular junction in Guinea pig gallbladder? ### Response:
These results show that opiates can cause presynaptic inhibition of excitatory neurotransmission at 2 sites within the wall of the gallbladder: vagal preganglionic terminals in ganglia and neuromuscular nerve terminals. These findings support the concept that opiates can contribute to gallbladder stasis by inhibiting g...
### Instruction: Does chronic ET ( A ) receptor blockade prevent endothelial dysfunction of small arteries in apolipoprotein E-deficient mice? ### Response:
Severe hypercholesterolemia in apoE-deficient mice is associated with attenuation of NO-mediated relaxation to acetylcholine and increased vascular endothelin-1 content. Chronic ET(A) receptor blockade may provide a new therapeutic approach to improve NO-mediated endothelium-dependent vasomotion in small arteries.
### Instruction: Does cytosolic free magnesium modulate Na/Ca exchange currents in pig myocytes? ### Response:
Cytosolic free magnesium modulates the I(NCX) over a physiologic range independent of [ATP](i). Reduced [Mg(2+)](i) in heart failure could contribute to altered calcium regulation of the NCX, contributing to the altered heart failure phenotype through enhanced NCX activity.
### Instruction: Do high plasma concentrations of human urotensin II alter local or systemic hemodynamics in man? ### Response:
In contrast to our hypothesised role of hUII, we found no vasoactive responses to hUII in vivo, consistent with recent in vitro studies in human blood vessels, but in contrast to non-human primate studies in vivo. Our data do not support a key role for hUII in the regulation of vascular tone and resting blood pressure ...
### Instruction: Do [ Functional reconstruction of mandible by using vascularized fibular free flap and one-stage rehabilitation of the implant ]? ### Response:
This is a good approach to rehabilitate bone function by using vascularized fibular free flap and one-stage implant placement.
### Instruction: Does the immune response to corneal allograft require a site-specific draining lymph node? ### Response:
The data show that a single specific lymph node, i.e., the SM node, is the major DLN involved in corneal graft rejection whereas its nearest neighbor, the SC DLN, not only cannot substitute for the SM node in priming the immune response but may be involved with the spleen in immune privilege. Retransplantation studies ...
### Instruction: Does leukocyte depletion attenuate expression of neutrophil adhesion molecules during cardiopulmonary bypass in human beings? ### Response:
The major findings of the present study in human subjects undergoing elective cardiac operations with cardiopulmonary bypass are as follows: (1) bypass was associated with an up-regulation of the adhesion molecules L-selectin, CD11b, and CD11c but with no significant change in CD11a expression, and (2) the clinical use...
### Instruction: Does free/total PSA ratio improve prediction of pathologic stage and biochemical recurrence after radical prostatectomy? ### Response:
These results suggest that the F/T PSA ratio is not helpful for the prediction of organ-confined disease and PSA recurrence after radical prostatectomy.
### Instruction: Does mild hypothermia induced before cardiac arrest reduce brain edema formation in rats? ### Response:
Mild hypothermia before CA decreases CA-induced brain edema. The hypothermia-elicited reduction in brain edema does not appear to be neutrophil-dependent and the early brain edema formation may not involve the proteolysis of occludin.
### Instruction: Does extracorporeal photopheresis in cutaneous T-cell lymphoma and graft-versus-host disease induce both immediate and progressive apoptotic processes? ### Response:
The early induction of apoptosis by ECP involves mitochondrial dysfunction, while later apoptosis is associated with the activation of caspases. CD10 expression was very weak and "late", preceded by a strong PS exposure. These apoptotic processes, in vivo, would induce the immediate and progressive phagocytosis of the ...
### Instruction: Is secretion of keratinocyte growth factor by cultured human endometrial stromal cells induced through a cyclic adenosine monophosphate-dependent pathway? ### Response:

In low-risk patients with chest pain, continuous 12-lead ST-segment monitoring provides significant incremental diagnostic and prognostic information to currently used clinical, enzymatic, and ECG data, and is helpful in identifying the subset of patients with a worse in-hospital outcome.
### Instruction: Does cardiopulmonary bypass copolymer surface modification reduce neither blood loss nor transfusions in coronary artery surgery? ### Response:
Our results show that the surface-modified CPB circuit decreased neither blood loss nor transfusions despite slightly better platelet function preservation compared to the unmodified circuit. This type of CPB circuit surface modification does not appear to improve clinical outcome in low-risk coronary artery surgery pa...
### Instruction: Is pulmonary blood flow inhomogeneously reduced after Euro Collins-preservation and lung transplantation? ### Response:
Two separate processes can be observed after single lung transplantation: (1) reduced regional pulmonary blood flow, which is a regional phenomenon restricted to the transplanted organ, and (2) extensive edema affecting both the transplanted and the native lung.
### Instruction: Do fruit juices inhibit organic anion transporting polypeptide-mediated drug uptake to decrease the oral availability of fexofenadine? ### Response:
Fruit juices and constituents are more potent inhibitors of OATPs than P-glycoprotein activities, which can reduce oral drug bioavailability. Results support a new model of intestinal drug absorption and mechanism of food-drug interaction.
### Instruction: Is stroke associated with coronary calcification as detected by electron-beam CT : the Rotterdam Coronary Calcification Study? ### Response:
In this population-based study, a markedly graded association was found between coronary calcification and stroke. The results suggest that coronary calcification as detected by electron-beam CT may be useful to identify subjects at high risk of stroke.
### Instruction: Does betaine supplementation decrease post-methionine hyperhomocysteinemia in chronic renal failure? ### Response:
GB supplementation had no effect on fasting tHcy in patients with chronic renal failure who were folate and pyridoxine replete, but it significantly decreased tHcy concentrations after methionine loading.

### Instruction: Does calmodulin inhibitor W-7 unmask a novel electrocardiographic parameter that predicts initiation of torsade de pointes? ### Response:
Selective suppression of TdP inducibility by W-7, without shortening the duration of cardiac repolarization, allowed identification of the UTA ratio as a new electrocardiographic index for predicting TdP onset. These findings are consistent with the idea that prolonged repolarization is not the proximate cause of arrhy...
### Instruction: Is somatotopic organization of the facial nucleus disrupted after lesioning and regeneration of the facial nerve : the histological representation of synkinesis? ### Response:
Our model provides a clear demonstration of the failure of adult facial nerve axons to make correct connections with their distal targets during regeneration. This model may be used to assess strategies aimed at minimizing synkinesis and, by assessing histology together with behavior, provides a more robust model than ...
### Instruction: Do thromboxane synthase inhibitors induce apoptosis in migration-arrested glioma cells? ### Response:
These data indicate that thromboxane synthase may represent a vortex of divergent signaling cascades that regulate motility and apoptosis in glioma cells. This paradigm may offer a novel perspective in the treatment of patients with malignant gliomas.
### Instruction: Is occurrence of extraarticular disease manifestations associated with excess mortality in a community based cohort of patients with rheumatoid arthritis? ### Response:
In this first community based study of extraarticular manifestations in RA, virtually all the excess mortality occurred in a subgroup of patients with severe extraarticular disease, suggesting that extraarticular disease is the major predictor of mortality in patients with RA.
### Instruction: Is maternal serum HCG higher in the presence of a female fetus as early as week 3 post-fertilization? ### Response:
Because a fetal gender-related difference in MSHCG can be demonstrated as early as week 3 post-fertilization, the difference may be attributed to placental factors and not to the effects of the fetal hypothalamic-hypophyseal-gonadal axis.
### Instruction: Does stability of cytadherence-related proteins P140/P110 in Mycoplasma genitalium require MG218 and unidentified factors? ### Response:
Expression of truncated MG218 in M. genitalium mg218 mutants appears to be due to the presence of a putative promoter upstream to the point of mg218 disruption; this truncated protein possesses the C-terminal region of MG218. However, pulse chase results from spontaneously arising, non-cytadhering P140-deficient M. gen...
### Instruction: Is acute postischemic renormalization of the apparent diffusion coefficient of water associated with reversal of astrocytic swelling and neuronal shrinkage in rats? ### Response:
Reperfusion-induced acute renormalization of ADC values is not associated with the reversal of neuronal shrinkage and astrocytic swelling that occur during ischemia. Conversely, the morphologic changes of astrocytes and neurons progressively worsen over time, although ADC values show a biphasic change.
