Sexual dimorphism in growth in the relative length of the forearm and relative knee height during adolescence 下载免费PDF全文

There are numerous studies concerning sexual dimorphism in body proportions, but only a few have investigated growth in the relative length of particular segments of the upper and lower limbs during adolescence. The aim of the study is an assessment of sex differences of longitudinal growth in the relative length of the forearm and knee height among adolescents. Sample involved 121 boys and 111 girls, participants of the Wroclaw Growth Study, examined annually between 8 and 18 years of age. Sexual dimorphism in six ratios: forearm length and knee height relatively to: trunk, height, and limb length were analyzed using a two‐way analysis of variance with repeated measurements. The sex and age relative to an estimate of maturity timing (3 years before, and after age class at peak height velocity [PHV]) were independent variables. All of the ratios showed significant sex differences in interaction with age relative to age at PHV. The relative length of the forearm, in boys, did not change significantly with the years relative to age at PHV, whereas in girls, was the lowest in the two first age classes and afterward significantly increased just 1 year before and during the adolescent growth spurt, remaining unchanged in further age classes. For relative knee height no clear pattern for sex differences was noticed. It is proposed that relatively longer forearms, particularly in relation to the trunk in girls, could have evolved as an adaptation to more efficient infant carrying and protection during breastfeeding. 相似文献

Fungal hemolysins are potential virulence factors. Some fungal hemolysins belong to the aegerolysin protein family that includes
cytolysins capable of lysing erythrocytes and other cells. Here, we describe a hemolysin from Aspergillus terreus called terrelysin. We used the genome sequence database to identify the terrelysin sequence based on homology with other
known aegerolysins. Aspergillus terreus mRNA was isolated, transcribed to cDNA and the open reading frame for terrelysin amplified by PCR using specific primers.
Using the pASK-IBA6 cloning vector, we produced recombinant terrelysin (rTerrelysin) as a fusion product in Escherichia coli. The recombinant protein was purified and using MALDI-TOF MS determined to have a mass of 16,428 Da. Circular dichroism analysis
suggests the secondary structure of the protein to be predominantly β-sheet. Results from thermal denaturation of rTerrelysin
show that the protein maintained the β-sheet confirmation up to 65°C. Polyclonal antibody to rTerrelysin recognized a protein
of approximately 16.5 kDa in mycelial extracts from A. terreus. 相似文献

Niemann-Pick type C (NPC) disease is characterized by excessive accumulation of cholesterol in the late endosome/lysosome compartment. Some members of the annexin family of proteins such as annexin A2 (AnxA2) and annexin A6 (AnxA6) follow the same route as cholesterol during the endocytic pathway and are found, as AnxA6, attached to the membranes of the cholesterol storage compartment in NPC disease fibroblasts. Therefore, the purpose of this work was to test the hypothesis that AnxA6 participates in the NPC-induced changes in the organization of membrane microdomains resistant to solubilization by a nonionic detergent, Triton X-100, i.e., detergent-resistant microdomains (DRMs). Using cellular fractionation, fluorescence microscopy and specific antibodies we observed that in the absence of calcium AnxA6 was found in the DRM-depleted membrane fractions isolated from NPC and control fibroblasts. In the presence of calcium, AnxA6 re-located to the fractions enriched in DRMs only in the NPC cells, suggestive of AnxA6 participation in organization of these microdomains. 相似文献
