TL;DR: Examination of the in vivo fate of effector cells revealed that CD25(lo) cells, which are relatively less sensitive to IL-2, preferentially upregulate CD127 and CD62L and give rise to functional long-lived memory cells, and data support the hypothesis that prolongedIL-2 signals during priming promote terminal-effector differentiation.

TL;DR: The findings that bone is a storehouse for growth factors and that bone cells in culture produce and respond to bone growth factors suggest bone growth Factors may act as potential determinants of local bone formation.
Abstract: Bone volume is determined by the relative rates of bone formation and bone resorption. Recent research in several laboratories suggests that growth factors may act locally to modulate bone formation by stimulating osteoblast proliferation and activity. A number of bone-derived growth factors have been isolated and characterized from bone matrix extracts and from media conditioned by bone cells and bone organs in culture. The growth factors found in bone matrix include insulinlike growth factors I and II, transforming growth factor-beta, acidic and basic fibroblast growth factor, platelet-derived growth factor, and bone morphogenetic proteins. Conditioned medium from bone cells contains several of these growth factors and also hematopoietic factors. These bone matrix-derived growth factors have different biologic activities, including mitogenic, differentiating, chemotactic, and osteolytic activities. Evidence suggests that bone cells produce substantial quantities of growth factors for extracellular storage in bone matrix. Apart from being produced for extracellular storage, it is possible that growth factors secreted by bone cells have acute effects on their neighboring osteoblastic cells, i.e., paracrine action, or on themselves, i.e., autocrine action. The release of matrix-stored growth factors by bone resorption may mean that growth factors act as delayed paracrine agents, e.g., osteoblasts deposit growth factors in bone and later when these growth factors are released from bone via bone resorption, the growth factors stimulate osteoblast precursors to proliferate. The findings that bone is a storehouse for growth factors and that bone cells in culture produce and respond to bone growth factors suggest bone growth factors may act as potential determinants of local bone formation. This review is focused on the structure, regulation, and biologic actions of the known bone growth factors.

TL;DR: Experimental data suggest that the apoptotic cascades occur very early after the initial insult and may be related directly to physiologic sequela commonly associated with SAH.
Abstract: Apoptosis is the term given to programmed cell death, which has been widely connected to a number of intracranial pathologies including stroke, Alzheimer's disease, and more recently subarachnoid hemorrhage (SAH). Subarachnoid hemorrhage is a disease, without any form of effective treatment, that affects mainly the young and middle aged and as a result is responsible for severe disability in otherwise healthy and productive individuals. Despite intense research efforts in the field, we currently possess a very limited understanding of the underlying mechanisms that result in injury after SAH. However, a number of studies have recently indicated that apoptosis may be a major player in the pathogenesis of secondary brain injury after SAH. As a result, the apoptotic cascades present a number of potential therapeutic opportunities that may ameliorate secondary brain injury after SAH. Experimental data suggest that these cascades occur very early after the initial insult and may be related directly to physiologic sequela commonly associated with SAH. It is imperative, therefore, to obtain a thorough understanding of the early events that occur after SAH, which will enable future therapies to be developed.

TL;DR: In this paper, the authors found that higher consumption of milk and calcium is associated with a lower risk of colorectal cancer, and the inverse association for milk was limited to cancers of the distal colon and rectum.
Abstract: Background: Studies in animals have suggested that calcium may reduce the risk of colorectal cancer. However, results from epidemiologic studies of intake of calcium or dairy foods and colorectal cancer risk have been inconclusive. Methods: We pooled the primary data from 10 cohort studies in five countries that assessed usual dietary intake by using a validated food frequency questionnaire at baseline. For most studies, follow-up was extended beyond that in the original publication. The studies included 534 536 individuals, among whom 4992 incident cases of colorectal cancer were diagnosed between 6 and 16 years of follow-up. Pooled multivariable relative risks for categories of milk intake and quintiles of calcium intake and 95% confidence intervals (CIs) were calculated. All statistical tests were two-sided. Results: Milk intake was related to a reduced risk of colorectal cancer. Compared with the lowest category of intake (<70 g/day), relative risks of colorectal cancer for increasing categories (70-174, 175-249, and ≥250 g/day) of milk intake were 0.94 (95% CI = 0.86 to 1.02), 0.88 (95% CI = 0.81 to 0.96), and 0.85 (95% CI = 0.78 to 0.94), respectively (Ptrend <.001). Calcium intake was also inversely related to the risk of colorectal cancer. The relative risk for the highest versus the lowest quintile of intake was 0.86 (95% CI = 0.78 to 0.95; Ptrend = .02) for dietary calcium and 0.78 (95% CI = 0.69 to 0.88; Ptrend <.001) for total calcium (combining dietary and supplemental sources). These results were consistent across studies and sex. The inverse association for milk was limited to cancers of the distal colon (Ptrend <.001) and rectum (Ptrend = .02). Conclusion: Higher consumption of milk and calcium is associated with a lower risk of colorectal cancer. © Oxford University Press 2004, all rights reserved.

TL;DR: The dimension of individualism-collectivism, as identified by Hofstede (1980), was studied using items developed both theoretically and emically in nine diverse cultures in this paper.
Abstract: The dimension of individualism-collectivism, as identified by Hofstede (1980), was studied using items developed both theoretically and emically in nine diverse cultures. The dimension was found to be analysable into four stable etic factors: Individualism had two aspects (Separation from Ingroups and Self-Reliance with Hedonism) and collectivism had two aspects (Family Integrity and Interdependence with Sociability). These four factors are orthogonal to each other. The location of nine cultures on these four factors was used to compute a “collectivism” score which correlated r = + · 73 with Hofstede's (1980) collectivism scores for the nine cultures. This approach enables the measurement of individualism-collectivism in each culture as well as across cultures, and shows that different methods for measuring individualism-collectivism converge.
