This issue of Gerontology includes a response by van Bodegom et al. to Herndon's recent article on the implications of the grandmother hypothesis for studies of aging and cognition. Although this hypothesis will doubtlessly continue to stimulate discussion, we focus here on our contention that human and non-human primate life histories have evolved essential differences and that these should be...

Pulmonary carcinoma is uncommon after lung transplant, but doubtlessly affects recipient survival independently of other complications. Small cell lung cancer is much rarer after transplant than non-small cell lung cancer. We report a case of mediastinal small cell lung carcinoma confirmed by endobronchial ultrasound biopsy that occurred 18 months after a single lung transplant for interstitial...

We read with interest the article by Fries and Krishnan about equipoise, design bias and randomized controlled trials [1]. It is important to stress that equipoise is not the principle underlying company-driven clinical trials, which are doubtlessly necessary and useful for medical progress. As a rule, companies’ clinical research departments cannot afford the risk that their hypotheses are inv...

BACKGROUND The question whether euthanasia should be legalised has led to substantial public debate in France. The objective of this study in a sample of French physicians was to establish the potential determinants of a favourable opinion about euthanasia in general and when faced with a specific situation as embodied in the Humbert affair. METHODS The study was a cross-sectional survey inve...

By the end of the 20th century, the research of electromagnetic behavior of π-electrons in organic crystals made several outstanding achievements. Since 50’s, the epoch-making finding appeared every decade: enhanced conductivity in halogen complexes of aromatic hydrocarbons 1) (1954), highly conductive radical salts of a π-acceptor TCNQ 2) (1960), a charge transfer complex TTF-TCNQ with quasi-o...

Although known that purebreed cats are more likely to develop feline infectious peritonitis (FIP), previous studies have not examined the prevalence of disease in individual breeds. All cats diagnosed with FIP at a veterinary teaching hospital over a 16-year period were identified. Breed, sex and reproductive status of affected cats were compared to the general cat population and to mixed breed...

Fuzzy rules, doubtlessly one of the most powerful tools of fuzzy logic, have not only been used successfully in established application areas like control engineering and approximate reasoning, but more recently also in the field of data mining. In this chapter, we provide a synthesis of different approaches to fuzzy association analysis, that is, the data-driven extraction of interesting patte...

now that rapid changes in deferent aspects of human life have become a reality, innovations in policies and different programs can not be a motto but a necessity. islamic revolution of iran was an innovative phenomenon and iran-iraq war was a space for our inner abilities and creativities to burst out. doubtlessly, in narrating this war to our next generations, we must consider this principle, ...
