Early fossil hominins have often been assigned a chronological age on the basis of modern human data for tooth eruption. Better data and more sophisticated methods are now available to estimate their chronological age from modern human standards for stages of mineralization of individual teeth developing within the jaws. However, while comparisons with modern human dentitions are interesting, they can also be misleading as early hominin teeth and dentitions did not grow like modern human teeth. Chronological age can also be estimated using the microanatomy of tooth enamel and root dentine. Counts of incremental markings in enamel predict much younger ages at death for early fossil hominins than those based on modern human radiographic standards of dental development. Comparative evidence from the skeleton suggests that a greater proportion of adult body mass and stature was achieved earlier in the growth period of fossil hominins than it is in modern humans. The combined skeleto-dental evidence provides the basis for a hypothesis that the earliest hominins grew more like modern great apes, but that Homo erectus had a slightly more prolonged period of growth, and which was still not totally modern human-like in its pattern or timing.  相似文献

We studied the role of monocytes in the effect of myelopid and myelopeptides MP-1, MP-3, MP-5, and MP-6 on functional activity of peripheral blood lymphocytes in the reaction of blast transformation. Myelopeptides MP-1, MP-3, and MP-6 suppressed blast transformation of lymphocytes. The effect depended on the presence of monocytes in a cell culture. __________ Translated from Byulleten' Eksperimental'noi Biologii i Meditsiny, Vol. 140, No. 7, pp. 85–87, July, 2005  相似文献

Accurate surface anatomy is a key component of safe clinical practice. But how consistent are modern clinical and surface anatomy texts in their reporting of common surface anatomy landmarks? Thirteen popular texts in common use were analyzed in detail: one clinical and anatomical reference text; seven clinical anatomy texts; two surface anatomy texts; and three clinical examination texts. Content relating to surface anatomy was reviewed, summarized, and assessed for consistency. Four main findings emerged: (i) there are numerous inconsistencies in clinically important surface markings (e.g., the femoral artery in the groin, superficial and deep inguinal rings, and accessory nerve in the posterior triangle), including inconsistencies within some texts; (ii) there is a consensus on many surface markings, e.g., the spleen and termination of the spinal cord; (iii) few texts address variation in surface anatomy related to age, sex, body mass, posture, respiration, and ethnicity; and (iv) the three standard clinical examination texts included in this review contain comparatively little surface anatomy. Seven surface anatomy landmarks were redefined within an evidence‐based framework: termination of the spinal cord, supracristal plane, base of the appendix, renal length, the deep inguinal ring, the femoral artery in the groin, and the accessory nerve in the posterior triangle of the neck. An evidence‐based framework is essential if surface anatomy is to be accurate and clinically relevant. Clin. Anat. 23:922–930, 2010. © 2010 Wiley‐Liss, Inc.  相似文献

Progress in understanding hominoid dental development   总被引:5,自引:3,他引:2  
Teeth preserve a record of the way they grow in the form of incremental markings in enamel, dentine and cementum. These make it possible to reconstruct cellular activity and the timing of dental development in living and fossil primates, including hominids. They also provide a way of exploring the mechanisms that underlie morphological change during evolution and the nature of the relationship between ontogeny and phylogeny. All living great apes are dentally mature by about 11 y, irrespective of their body mass. While the early period of root formation in living great apes is shorter than in modern humans, enamel takes approximately the same time to form, irrespective of how thick it is. In general, differences in the total time taken to form enamel seem not to be due to differences in the rate at which enamel and dentine are secreted, but rather to faster or slower rates of differentiation of ameloblasts and odontoblasts and therefore to the number of secretory cells active at any one time during tooth formation. Tooth size, especially height, may influence the sequence of appearance of tooth mineralisation stages. The space available in the jaws may also have an influence on both the timing of tooth bud/crypt appearance and the sequence of gingival emergence. When each of these potential influences on dental development are carefully considered, and incremental markings used to calibrate key events, the developing dentition can provide an estimate of the period of dental maturation in fossil hominoids. However, the influence of body mass on the period of dental development among primates remains unclear. The earliest hominoids, dated at around 18 Mya, may still have had modern monkey‐like maturational profiles, and the earliest hominids, dated between 1.8 and 3.7 Mya, modern great ape‐like maturational profiles. Exactly when the extended or prolonged modern human‐like maturational profile first appeared remains debatable, but the most secure suggestion might be at the time of the appearance of the earliest archaic Homo sapiens, when brain size and body mass were finally both within the ranges known for modern humans. But at present we should not reject the hypothesis that an extended, modern human‐like, maturational profile arose more than once during human evolution in parallel with an increase in brain size.  相似文献

The immunologic activity of lymph cells obtained in the course of therapeutic drainage of the thoracic duct was studied in 14 patients with subhepatic jaundice of varied genesis. The blast transformation of lymphocytes reaction showed that lymphocytes from lymph are capable of blast formation when exposed to the action of phytohemagglutinin, antilymphocytic -globulin, and certain bacterial antigens. The highest intensity of the reaction was found in cultures of lymph lymphocytes taken for these purposes on the 2nd–3rd days after the beginning of lymph drainage. In the course of lymphorrhea the ability of stimulated lymph cells to undergo blast formation is reduced. In the period of lymph drainage, no blast formation takes place in stimulated cultures of patients' blood cells. The majority of antigen-sensitive lymphocytes is thus in a reserve state in the lymphoid tissue of the body.Department of Infectious Diseases and Course in Emergency Surgery, V. I.

Populations of the rice blast fungus, Magnaporthe grisea, can be sorted into clonal lineages based on restriction fragment length polymorphisms (RFLPs) detected with the repetitive DNA sequence MGR586. Mechanisms that produce DNA-fingerprint variation among lineages, are not known. In the process of analyzing the meiotic segregation of MGR586 RFLPs we identified a novel polymorphism, called MGR586-P2, in one member of a sister-spore pair from a complete tetrad. Molecular cloning revealed that P2 was generated by a nearby insertion of a novel, long-terminal-repeat (LTR)-containing retrotransposon. Genetic analysis showed that P2 and its progenitor polymorphism (P1) are alleles of a single polymorphic locus termed MGR586-PL (PL). Surprisingly, we found that a strain harboring PL recurrently produced clonal descendants harboring P1, P2 and possibly a third allele designated P3. PL is not located near a telomeric region. Our results show that some DNA-fingerprint loci may be hypervariable and undergo recurrent rearrangements. These findings have implications for interpreting DNA-fingerprint profiles from M. grisea populations. Received: 9 January / 25 March 1996  相似文献

Transformed lymphocytes obtained by stimulating lymph node cells of CBA mice with phytohemagglutinin (PHA) do not give the graft versus host reaction (GVHR) if injected into sublethally irradiated (CBA×C57BL/6) F1 hybrids. In a population of PHA-stimulated cells the GVHR was induced by small lymphocytes having the same concentration of antigens, detectable by antilymphocytic serum, as intact lymphocytes.Department of Immunology, Medico-Biological Faculty, N.

The reaction of peripheral blood lymphocytes from healthy blood donors aged from 19 to 49 years to the mitogens phytohemagglutinin, concanavalin A (con A), and rabbit serum against human thymocytes (ATS) was investigated. A significant decrease in the proliferative response of the lymphocytes to con A was found in subjects over 30 years old. Significant negative correlation was found between the indices of the proliferative response and the age of the donors during stimulation by con A for the whole group of subjects, but for stimulation by ATS only for subjects aged 30–49 years. Analysis of the intensity of incorporation of [3H]-thymidine shows a decrease with age in the proportion of cells with intensively labeled nuclei and an increase in the number of cells with weak labeling of the nucleus both with a decrease in the indices of the proliferative response with age and also when no significant differences were found in these indices.Laboratory of General Pathophysiology, Institute of Psychiatry, Academy of Medical Sciences of the USSR, Moscow.
