Rheumatoid arthritis is a chronic degenerative autoimmune disease characterized by persistent inflammation of synovial membranes, which leads to cartilage destruction and bone erosion. To date, there are no effective therapies to slow the progress of this degenerative condition. Here, we evaluate the anti-arthritic effect of chebulanin, an abundant anti-inflammatory agent isolated from Terminalia chebula, in collagen induced arthritis in DBA/1 mice by intragastric administration.

We report on 2 unusual cases of the campomelic syndrome, the first being a fetus in whom the diagnosis was suspected in the 18th week and confirmed sonographically at 20 weeks. The second case concerns a 5 year old 46, XY girl with an exceptional longevity and a relatively favorable evolution.

Eighty-two people dating from 1975 to 1879 compared with 182 modern middle-class White and Black skeletons test the myths of radical changes produced by improved diet, less disease, and nineteenth century immigration. Longevity increases and health and growth improvement is clearest in reduced juvenile deaths (census data) and deepening of true pelvis. Stature increase is minimal (though seventeenth century Londoners and modern West Africans are shorter than Colonial to Modern Americans); teeth deteriorate and for cultural reasons fractures increase. Clavicles and forearms elongate.

Increased longevity and improved medical management of children with chronic illnesses has led to a focus on the short- and long-term consequences of these conditions on bone health. Bone loss is influenced by diet, malabsorption, and disease-related imbalances in bone turnover. It may be exacerbated by common medications, especially corticosteroids.

Bone mass declines progressively with age in both men and women from the age of approximately 30 y. Increased longevity will inevitability be associated with an increase in the incidence of osteoporosis, its associated complications, and incurred health care costs. Current pharmacologic approaches focus on inhibiting bone resorption in those with osteoporosis but do little to improve bone mass. Increased understanding of the cellular events responsible for normal bone formation has led to multiple pathways that can be targeted to positively influence bone mass.

BACKGROUND: Calorie restriction (CR) is promoted to increase longevity, yet this regimen could lead to bone loss and fracture and therefore affect quality of life. METHODS: Forty-six individuals were randomized to 4 groups for 6 months: (1) healthy diet (control group); (2) 25% CR from baseline energy requirements (CR group); (3) 25% energy deficit by a combination of CR and increased aerobic exercise (CR + EX group); and (4) low-calorie diet (890 kcal/d; goal, 15% weight loss) followed by weight maintenance (LCD group).

BACKGROUND: Aging is a complex multifactorial process characterized by accumulation of deleterious changes in cells and tissues, progressive deterioration of structural integrity and physiological function across multiple organ systems, and increased risk of death. METHODS: We conducted a review of the scientific literature on the relationship of advanced glycation end products (AGEs) with aging. AGEs are a heterogeneous group of bioactive molecules that are formed by the nonenzymatic glycation of proteins, lipids, and nucleic acids.

Tissue banks currently warrant an interdisciplinary management leading to detect and address pressure conflicts taking into account ethical aspects, the safety and quality of the tissues provided, behavior under the principles of altruism, solidarity and equity, and the procurement of deceased donor tissues.

Whether man is predisposed to lethal violence, ranging from homicide to warfare, and how that may have impacted human evolution, are among the most controversial topics of debate on human evolution. Although recent studies on the evolution of warfare have been based on various archaeological and ethnographic data, they have reported mixed results: it is unclear whether or not warfare among prehistoric hunter-gatherers was common enough to be a component of human nature and a selective pressure for the evolution of human behaviour.
