Some 30 years ago, when researching a thesis on the history of Tuvalu, I could not help but be aware of the impact of the atoll environment on the lives of the inhabitants. The word ‘environment’ crops up repeatedly in the thesis, but I thought in terms of the environment’s effect on people and only marginally on human... |
ABSTRACT Transcription antitermination in the ribosomal operons of Escherichia coli results in the modification of RNA polymerase by specific proteins, altering its basic properties. For such alterations to occur, signal sequences in rrn operons are required as well as individual interacting proteins. In this study we ... |
Root growth is stimulated by plant hormones, such as gibberellin. Gibberellin opposes the action of nuclear-localized DELLA proteins that repress growth. RGA is one such DELLA protein. Fu and Harberd report that Arabidopsis mutants deficient for gibberellin (gal-3) had shorter roots than wild-type plants and that Arabi... |

Idiopathic (unspecific) low back pain is the most common rheumatological complaint. Results of international studies give evidence that in about 80 % of the cases a specific diagnosis is not possible, thus creating an unsatisfactory situation for the orthopaedist. We feel that it is necessary to keep the discussion on ... |
METHODS |
In the context of a research project on the need for rehabilitation, 335 subjects suffering from severe low back pain were subjected to a physical (orthopaedic-neurological) examination. Also, a questionnaire was distributed assessing psychological status, work situation, comorbid conditions, risk factors, and demograp... |
RESULTS |
In more than half of the subjects, clues for a specific cause for the back pain were found; in more than one third of the cases there were one or more neurological signs. |
CONCLUSION |
The data presented demonstrate that specific causes for low back pain might be more common than generally assumed. This leads us to the conclusion that there is a need for more clinically-oriented, population-based (epidemiological) research on possible pathologic causes of low back pain and comorbid conditions.Coronar... |
The present study examined the angiographic characteristics and prognosis of young males under 40 years of age with acute myocardial infarction (AMI) and familial hypercholesterolemia (FH). The study group was divided into an FH group (n=16) and a non-FH group (n=27). Lesion morphology was classified as complex or smoo... |
We describe a novel approach for shop poor control combining a distributed multi-agent structure and computational intelligence techniques. Shop floor activities are controlled by a network of autonomous agents. Each agent makes its decision with a fuzzy algorithm evaluating all the alternative actions with multiple cr... |

INTRODUCTION |
Erectile dysfunction (ED) treatment studies do not routinely measure "treatment effectiveness," a function of treatment response (based on efficacy and tolerability) and treatment satisfaction (both patient and partner satisfaction). The ED Treatment Satisfaction Scale (TSS) is a brief, comprehensive self-report measur... |
AIM |
To measure, for the first time in an ED treatment study, pre- and post-treatment patient and partner satisfaction with the TSS. |
METHODS |
A randomized, double-blind, placebo-controlled, parallel-group, multi-institutional comparison of the efficacy and safety of flexible-dose vardenafil was performed in 229 couples (treated man with ED >6 months and untreated woman partner aged > or =18 years without sexual dysfunction [defined as a total Female Sexual F... |
MAIN OUTCOME MEASURES |
Couples completed the TSS throughout the trial. Couples also completed the modified Sexual Life Quality Questionnaire-Quality of Life domain (mSLQQ-QoL) and men completed the International Index of Erectile Function-erectile function domain (IIEF-EF). Analysis of covariance produced least squares (LS) mean domain score... |
RESULTS |
TSS domain scores increased from baseline to last observation carried forward (LOCF) in the vardenafil-treated men and untreated women partners, but exhibited little change for the placebo group (P < 0.0001 vs. placebo). For both patients and partners in the vardenafil group, correlations between TSS domains, the IIEF-... |
CONCLUSIONS |
The TSS detected that vardenafil was superior to placebo on treatment satisfaction from both patient and partner perspectives. The TSS holds promise for evaluating "treatment effectiveness" by measuring more general treatment satisfaction.Ignition study of a petrol/CNG single cylinder engine |

Introduction |
The treatment of avascular necrosis of the femoral head (AVNFH) is based on invasive (e.g., core decompression) and non-invasive methods (e.g., hyperbaric oxygen therapy - HBO2). The purpose of the present study is to evaluate the effect of HBO2 on the quality of life (QoL) of patients with AVNFH. |
Methods |
This was a prospective observational non-controlled study of patients with AVNFH treated by HBO2. It was conducted, with the use of Steinberg scale, on 73 patients with AVNFH Stage I or II who were treated with HBO2. Patients' QoL was assessed with EuroQol-5D-5L (EQ), Harris Hip Score (mHHS), MAHORN (MHOT), and VAS, in... |
Results |
All 73 patients (67.1% males, 32.9% females, mean age: 40.34, SD ±± 9.99) participated in the study. Steinberg scale, mean EQ (F (1, 57) = 25.18, η2 = .306 and F (1, 43) = 43.402, η2 = .502); mHHS (F (1, 61) = 67.13, η2 = .524) and F (1, 43) = 31.84, η2 = .425); MHOT (F (1, 61) = 11.68, η2 = .161) and F (1, 43) = 98.01... |
Conclusion |
HBO2 treatment does not induce alteration of quality of life and is well tolerated and accepted by patients.Semi-Supervised Hyperspectral Subspace Learning Based on a Generalized Eigenvalue Problem for Regression and Dimensionality Reduction |
