estimating canine tooth crown height in early australopithecus
Journal of Human Evolution, 2009Co-Authors: Michael J Plavcan, Carol V Ward, Faydre L PaulusAbstract:Canine tooth size reduction and the associated reduction in canine dimorphism is a basal hominin character that also provides important evidence for models of behavioral evolution. Two specimens of Australopithecus anamensis (KNM-KP 29287 and KNM-KP 29283) that do not preserve the canine crown, but do preserve the root or alveolus, appear to suggest that canine size variation and canine dimorphism in this species may have been greater than in other hominins. We evaluate canine root and crown dimensions in a series of extant hominoids, and estimate canine crown height in Australopithecus afarensis and A. anamensis. Our results demonstrate that it is possible to generate estimates of canine crown height from basal canine crown and root dimensions with a moderate degree of accuracy. Estimates of maxillary canine crown size for A. anamensis are slightly larger than those of A. afarensis, and are approximately the same size as canines of modern female chimpanzees. Estimated mandibular canine crown height is very similar in the two species. Variation within the A. anamensis sample of estimated canine crown heights is similar to that of modern humans, suggesting a low degree of sexual dimorphism. Inclusion of estimates for KNM-KP 29287 and KNM-KP 29283 does not substantially increase either the estimate of overall canine size or variation for A. anamensis.

morphology of australopithecus anamensis from kanapoi and allia bay kenya
Journal of Human Evolution, 2001Co-Authors: Carol V Ward, Meave G Leakey, Alan WalkerAbstract:The hominid species Australopithecus anamensis was originally described in 1995, with new specimens and more secure dates given in 1998. This paper lists all fossils attributed to A. anamensis, and provides anatomical descriptions of those not yet described in detail with photographs of all but undiagnostic fragments. We also provide comparative analysis of these specimens. The A. anamensis holotype mandible was found at Kanapoi, as were most of the paratypes. The Allia Bay sample is less well represented, and does not preserve many anatomical elements diagnostic of this species. Still, the Allia Bay sample most closely resembles that from Kanapoi, and we suggest that for the time being it be retained as A. anamensis. A. anamensis most closely resembles A. afarensis, but can be distinguished from it in many features. Most of these features are inferred to be primitive for the genus. Based on the limited postcranial evidence available, A. anamensis appears to have been habitually bipedal, although it retained some primitive features of its upper limbs. A. anamensis differs from A. afarensis in having narrower, more parallel jaws with a very slightly more ape-like canine/premolar complex than is found in A. afarensis, although not as ape-like as in Ardipithecus ramidus. It had slightly larger lower lateral incisors, a unique upper canine morphology, and a different structure of the lateral nasal aperture than A. afarensis. A. anamensis had at least as great a range of body size, and perhaps slightly greater canine dimorphism, although this is difficult to determine. At present, there appears to be no autapomorphies precluding A. anamensis from ancestry of A. afarensis.

the new hominid speciesaustralopithecus anamensis
Evolutionary Anthropology, 1999Co-Authors: Carol V Ward, Meave G Leakey, A WalkerAbstract:Australopithecus anamensis1 is the earliest species of this genus to have been found. Fossils attributed to A. anamensis have been recovered from sediments dating to between 3.8 and 4.2 mya at the sites of Kanapoi and Allia Bay in northern Kenya. A. anamensis is still poorly known in comparison with other early hominid species, but the material discovered so far displays primitive features along with more derived characteristics typical of later Australopithecus species. This mix of features suggests that A. anamensis belongs near the ancestry of this genus. Indeed, it may eventually be determined that this was the earliest Australopithecus species. © 1999 Wiley-Liss, Inc.

new specimens and confirmation of an early age for australopithecus anamensis
Nature, 1998Co-Authors: Meave G Leakey, Carol V Ward, Craig S Feibel, Ian Mcdougall, Alan WalkerAbstract:The discovery of Australopithecus anamensis fossils from strata lying between tephra dated at 4.17 and 4.12 million years ago, and from slightly higher strata not well constrained in age by overlying dated units, provoked the claim that more than one species might be represented: it was suggested that the stratigraphically higher fossils, which include the important tibia, humerus and a large, presumed male, mandible (KNM-KP 29287), might belong to a later, more derived hominid. We have recovered new fossils from Kanapoi and Allia Bay, Kenya, during field work in 1995-1997 that confirm the primitive status of Australopithecus anamensis, the earliest species of Australopithecus. Isotope dating confirms A. anamensis' intermediate age as being between those of Ardipithecus ramidus and Australopithecus afarensis. New specimens of maxilla, mandible and capitate show that this species is demonstrably more primitive than A. afarensis. A lower first deciduous molar (dm 1) is intermediate in morphology between that reported for Ardipithecus ramidus and A. afarensis. Single-crystal 40Ar-39Ar age determinations on the Kanapoi Tuff show that, except for a large mandible, all of the hominid fossils from Kanapoi are from sediments deposited between 4.17+/-0.03 and 4.07+/-0.02 million years ago.

Risk factors for urinary incontinence in women
Universidade de São Paulo Escola de Enfermagem, 2015Co-Authors: Higa Rosângela, Lopes, Maria Helena Baena De Moraes, Reis, Maria José DosAbstract:The goal of this study was to conduct a review of the main papers published between 1983 and 2003 on the main risk factors for urinary incontinence (UI) in women. Thirty-eight publications in English and Portuguese were analyzed using the MEDLINE and LILACS databases as well as through research in libraries. There is evidence that the main risk factors are age, pelvic floor trauma, hereditary factors, race, menopausal status, obesity, chronic diseases, use of some sympathomimetics and parasympatholitics, constipation, smoking, coffee consumption and intense abdominal exercises. Nurses are able to identify these factors through Anamnesis and determine interventions for the prevention and treatment of UI, thus contributing to improve incontinent women's quality of life.Trata-se de um estudo de revisão bibliográfica com o objetivo de identificar os principais fatores de risco ou associados à incontinência urinária (IU) na mulher.
