an organism. The lace plant (Aponogeton madagascariensis) produces perforations in its leaves through PCD. The leaves of the plant consist of a latticework of longitudinal and transverse veins enclosing areoles. PCD occurs in the cells at the center of these areoles and progresses outwards, stopping approximately five cells from the vasculature. The role of mitochondria during PCD has been recognized in animals; however, it has been less studied during PCD in plants.\n\nThe following paper elucidates the role of mitochondrial dynamics during developmentally regulated PCD in vivo in A. madagascariensis. A single areole within a window stage leaf (PCD is occurring) was divided into three areas based on the progression of PCD; cells that will not undergo PCD (NPCD), cells in early stages of PCD (EPCD), and cells in late stages of PCD (LPCD). Window stage leaves were stained with the mitochondrial dye MitoTracker Red CMXRos and examined. Mitochondrial dynamics were delineated into four categories (M1-M4) based on characteristics including distribution, motility, and membrane potential (ΔΨm). A TUNEL assay showed fragmented nDNA in a gradient over these mitochondrial stages. Chloroplasts and transvacuolar strands were also examined using live cell imaging. The possible importance of mitochondrial permeability transition pore (PTP) formation during PCD was indirectly examined via in vivo cyclosporine A (CsA) treatment. This treatment resulted in lace plant leaves with a significantly lower number of perforations compared to controls, and that displayed mitochondrial dynamics similar to that of non-PCD cells."} +{"doc_id": "pubmedqa_16418930", "source_dataset": "pubmed_qa/pqa_labeled", "corpus": "medical", "dataset": "pubmedqa", "source_row_index": 2, "pubid": 16418930, "reference": "PubMed PMID 16418930", "page": "", "text": "Assessment of visual acuity depends on the optotypes used for measurement.

Animals were divided into groups A, the first eight, and B, the last seven cases. Data were statistically analyzed.\n\nWe performed fifteen RPNs. The operative time varied from 15 to 50 minutes (median 30 minutes). Blood loss varied from 5 to 100 mL (median 20 mL).

Cohesive tensile strength testing directly supported these morphologic findings as the stronger, more rigid regions of the cornea were located anteriorly and peripherally. This suggests that PRK and ASA, and secondarily SBK, should be biomechanically safer than conventional LASIK with regard to risk for causing keratectasia after surgery. Because adult human corneal stromal wounds heal slowly and incompletely, all excimer laser keratorefractive surgical techniques still have some distinct disadvantages due to inadequate reparative wound healing. Despite reducing some of the risk for corneal haze compared to conventional PRK, ASA cases still can develop corneal haze or breakthrough haze from the hypercellular fibrotic stromal scarring.

A total of 316 patients met the inclusion criteria of treatment with one of the AIs for>or = 3 months and availability of a dualenergy X-ray absorptiometry (DEXA) during this treatment. Arthralgia, generalized bone pain and/or myalgia, bone fracture after beginning AIs, any tamoxifen treatment, and Ca/Bis therapy were recorded.\n\nOur study demonstrates a significant association between symptoms and DEXA-BMD results (P<.001). Similarly, the group receiving tamoxifen before AIs had fewer patients with arthralgia or generalized bone pain/myalgia or bone fracture (P<.001). Furthermore, the group receiving AIs plus Ca/Bis had more patients without musculoskeletal symptoms and had fewer fractures. Finally, the group receiving steroidal AIs compared with nonsteroidal AIs had more patients with arthralgia or generalized bone pain and/or myalgia, and bone fractures (P<.001)."} +{"doc_id": "pubmedqa_22706226", "source_dataset": "pubmed_qa/pqa_labeled", "corpus": "medical", "dataset": "pubmedqa", "source_row_index": 139, "pubid": 22706226, "reference": "PubMed PMID 22706226", "page": "", "text": "To determine current practice and to assess the value of routine follow-up procedures for endometrial cancer surveillance.

Research into health inequalities frequently fails to recognise spatial heterogeneity in the deprivation-health relationship, assuming that global relationships apply uniformly across geographical areas. In this study, exploratory spatial data analysis methods are used to assess local patterns in deprivation and mortality. Spatial regression models are then implemented to examine the relationship between deprivation and mortality more formally.\n\nThe initial exploratory spatial data analysis reveals concentrations of high standardized mortality ratios (SMR) and deprivation (hotspots) in the West of Scotland and concentrations of low values (coldspots) for both variables in the rest of the country. The main spatial regression result is that deprivation is the only variable that is highly significantly correlated with all-cause mortality in all models. However, in contrast to the expected spatial heterogeneity in the deprivation-mortality relationship, this relation does not vary between regions in any of the models. This result is robust to a number of specifications, including weighting for population size, controlling for spatial autocorrelation and heteroskedasticity, assuming a non-linear relationship between mortality and socio-economic deprivation, separating the dependent variable into male and female SMRs, and distinguishing between West, North and Southeast regions. The rejection of the hypothesis of spatial heterogeneity in the relationship between socio-economic deprivation and mortality complements prior research on the stability of the deprivation-mortality relationship over time."} +{"doc_id": "pubmedqa_23025584", "source_dataset": "pubmed_qa/pqa_labeled", "corpus": "medical", "dataset": "pubmedqa", "source_row_index": 336, "pubid": 23025584, "reference": "PubMed PMID 23025584", "page": "", "text": "That alcohol consumption is strongly influenced by the drinking behavior of social company has been demonstrated in observational research.

The postoperative mean systolic pressure gradient ranged from 10.5 to 22.2 mmHg in the Mosaic group, and from 9.4 to 12.6 mmHg in the Perimount group; it was significantly lower for 21 and 23 Perimount valves than for 21 and 23 Mosaic valves. The EOA ranged from 0.78 to 2.37 cm2 in Mosaic patients, and from 0.95 to 2.12 cm2 in Perimount patients.

Fondaparinux's extended half-life of 17-21 hours complicates its use as a perioperative bridging therapy. The ideal time for discontinuation before surgery is an issue, particularly in surgeries with a high bleeding risk or in which neuraxial anesthesia is used. Guidance for perioperative bridging with fondaparinux must be derived from pharmacokinetic data, surgical prophylaxis trials, case reports, and anesthesia guidelines. Published trials used fondaparinux sodium 2.5 mg daily for venous thromboembolism prophylaxis in surgical patients, and the majority avoided its use before surgery in patients receiving neuraxial anesthesia. Three case reports cited the use of fondaparinux sodium as perioperative bridge therapy; one used a 2.5-mg dose, and the other two used a full treatment dose of 7.5 mg. Furthermore, professional anesthesia guidelines conflict in their recommendations regarding the timing of drug administration with neuraxial catheter use. For these reasons, it may be optimal to avoid fondaparinux use before surgery. In some instances, the use of low-molecular-weight heparin or inpatient use of i.v. unfractionated heparin is not possible, is contraindicated, or has limited efficacy, such as a patient with history of heparin-induced thrombocytopenia or antithrombin III deficiency.

Pearson's correlation coefficients were calculated to quantify bivariate relationships.\n\nBilaterally, CIMT was significantly different among the three cardiovascular phenotypes (right: p < 0.001, F = 33.8; left: p < 0.001, F = 48.6). CIMT had a higher c-statistic for differentiating stroke versus normotension (c = 0.78 right; 0.82 left, p < 0.001) and hypertension versus normotension (c = 0.65 right; 0.71 left, p < 0.001) than several traditional vascular risk factors.

A germline mutation was detected in 230 of 404 patients who were diagnosed after onset of bowel symptoms (rectal bleeding, abdominal pain, diarrhoea). When these patients were grouped according to the different sites of mutations, mean values for age at onset of disease differed significantly: patients carrying APC mutations at codon 1309 showed a disease onset 10 years earlier (mean age 20 years) compared with patients with mutations between codons 168 and 1580 (except codon 1309) (mean age 30 years), whereas patients with mutations at the 5' end of codon 168 or the 3' end of codon 1580 were diagnosed at a mean age of 52 years. Within each group of patients however large phenotypic variation was observed, even among patients with identical germline mutations. A higher incidence of desmoids was found in patients with mutations between codons 1445 and 1580 compared with mutations at other sites, while no correlation between site of mutation and presence of duodenal adenomas was observed."} +{"doc_id": "pubmedqa_19145527", "source_dataset": "pubmed_qa/pqa_labeled", "corpus": "medical", "dataset": "pubmedqa", "source_row_index": 910, "pubid": 19145527, "reference": "PubMed PMID 19145527", "page": "", "text": "The primary objective of the study was to determine emergency medical services (EMS) professionals' opinions regarding participation in disease and injury prevention programs.

These inhibitory signals satisfy the criteria that distinguish mossy fiber-CA3 synapses: high sensitivity to metabotropic glutamate-receptor agonists, facilitation during repetitive stimulation, and N-methyl-D-aspartate (NMDA) receptor-independent long-term potentiation."} +{"doc_id": "pubmedqa_17342562", "source_dataset": "pubmed_qa/pqa_labeled", "corpus": "medical", "dataset": "pubmedqa", "source_row_index": 946, "pubid": 17342562, "reference": "PubMed PMID 17342562", "page": "", "text": "Some patients with suspected common bile duct (CBD) stones are found to have sludge and no stones.

Repeated measures analysis of variance was used to compare the medication's efficacy and side effects.\n\nA total of 120 patients presenting to the emergency department met the inclusion criteria. Of these, 62 patients (51.7%) were given 10 mg metoclopramide as a slow intravenous infusion over 15 min (SIG group) and 58 patients (48.3%) were given 10 mg metoclopramide intravenous bolus infusion over 2 min (BIG group). 17 of the 58 patients in the BIG group (29.3%) and 4 of the 62 patients (6.5%) in the SIG group had akathisia (p = 0.001). There were no significant differences between the BIG and SIG groups in terms of mean headache scores (p = 0.34) and no adverse reactions in the study period.

Nevertheless, it is clear that additional interventions will be needed to maintain women's adherence to mammography.
