  • The population of Western countries is aging, and cancer in older aged persons is becoming increasingly common. The management of these neoplasms is a novel problem. Direct information on the outcome of cancer prevention and of cytotoxic chemotherapy in older individuals is scarce, especially for those aged 80 and over, and it is not clear whether the same process should direct medical decisions in younger and older persons. It is reasonable to assume that the benefits of cancer prevention and treatment diminish and the dangers increase with age.

  • The forty-fifth volume of this series contains eight reviews written by an international array of authors; as usual, the reviews range widely in subject and taxonomic and geographic coverage. The editors welcome suggestions from potential authors for topics they consider could form the basis of future appropriate contributions. Because an annual publication schedule necessarily places constraints on the timetable for submission, evaluation and acceptance of manuscripts, potential contributors are advised to make contact with the editors at an early stage of preparation.

  • Plants defend themselves from other organisms by elaborating bioactive chemical defences. This is the essential basis of the use of herbal medicines that still represents a major therapeutic resort for much of humanity However, at the outset, it must be stated that any plant that is not part of our evolved dietary cultures is potentially dangerous. Commercial herbal medicinal preparations approved by expert regulatory authorities have a significant place in mainstream conventional medicine and in complementary medicine.

  • This book presents a full spectrum of views on current approaches to modeling cell mechanics. The authors of this book come from the biophysics, bioengineering, and physical chemistry communities and each joins the discussion with a unique perspective on biological systems. Consequently, the approaches range from finite element methods commonly used in continuum mechanics to models of the cytoskeleton as a cross-linked polymer network to models of glassy materials and gels.

  • Biological sciences in nursing has seen a change in status over the last 20 years. As a nurse educator, I became aware that with the introduction of the ‘nursing model’ all signs of biology were banished from the curriculum. Anatomy and physiology were thought to be akin to the ‘medical model’, and as such they fell outside the nurse’s territory. At all costs, nurses had to be seen as autonomous practitioners in their own right.

  • The average total daily energy expenditure is higher in obese than lean individuals when measured at stable weight. However, energy expenditure falls as weight is lost, due in part to loss of lean body mass and to decreased sympathetic nerve activity. When reduced to near-normal weight and maintained there for a while, (some) obese individuals have lower energy expenditure than (some) lean individuals. There is also a tendency for those who will develop obesity as infants or children to have lower resting energy expenditure rates than those who remain lean.

  • -Sitosterol, stigmasterol, cardamomin (1), chalconaringenin 2-O-methyl ether (2), alpinetin (3), and naringenin 5-O-methyl ether (4) were isolated from the MeOH extract of Alpinia conchigera Griff. (Zingiberaceae). Their structures were determined on the basis of spectroscopic analyses. The antimicrobial and free radical scavenging activities of the isolates 1-4 were evaluated in correlation with those of the soluble fractions.
