Six female long distance runners in the vocational society were evaluated in order to determine their maximal oxygen uptake (VO2max) .In addition, VO2max of high school student girls were measured.The examination proved that the vocational group have a higher level VO2max than the student group.It proved that there is a definite relationship between VO2max and ability to run 5000m.High grade VO2max does not always ensure better competitive records, but it is beneficial for a long distance runner.
Purpose To evaluate the progression of early age-related macular degeneration to neovascular age-related macular degeneration (nAMD), and identify the abnormal fundus autofluorescence (FAF) patterns and markers of choroidal neovascularization (CNV) in fellow eyes of patients with unilateral nAMD. Methods Sixty-six patients with unilateral nAMD who developed abnormal FAF in the fellow eyes were enrolled in this multicenter, prospective, observational study, and followed-up for 5 years. FAF images on Heidelberg Retina Angiogram Digital Angiography System (HRA) or HRA2 were classified into eight patterns based on the International Fundus Autofluorescence Classification Group system. The patients in which the fellow eyes progressed to advanced nAMD, including those who did not develop nAMD, were assessed based on the following factors: baseline FAF patterns, age, sex, visual acuity, drusen, retinal pigmentation, baseline retinal sensitivity, family history, smoking, supplement intake, hypertension, body mass index, and hematological parameters. Results Of the 66 patients, 20 dropped out of the study. Of the remaining 46 patients, 14 (30.42%, male: 9, female: 5) progressed to nAMD during the 5-year follow-up. The most common (50% eyes) FAF pattern in the fellow eyes was the patchy pattern. According to the univariate analysis, CNV development was significantly associated with age, supplement intake, and low-density lipoprotein levels (p<0.05). Multivariable analysis revealed that patients who showed non-compliance with the supplement intake were more likely to develop nAMD (p<0.05). No significant association was found between the patchy pattern and CNV development (p = 0.86). Conclusion The fellow eyes (with abnormal FAF) of patients with unilateral nAMD may progress from early to advanced nAMD. However, no FAF pattern was found that predicted progression in nAMD.
Two chicken B cell lines, termed MuH1 and MuH4, which are resistant to ouabain, were established as fusion partners for production of chicken monoclonal antibody from the parental cell lines R27H1 and R27H4 which were deficient in thymidine kinase activity. The MuH1 synthesized, but did not secrete μ chain, whereas the MuH4 secreted non-specific IgM. Fusions of the MuH1 and MuH4 with spleen cells from chickens immunized with human IgG resulted in successful preparations of hybridomas secreting antibodies specific to human IgG. Transformed cells insensitive to HAT appeared in many culture wells after cell hybridizations with R27H4, but on hybridization with MuH1 or MuH4 the appearance of such unfavorable cells could be avoided by the inclusion of ouabain in HAT medium. Thus, in comparison with the R27H4 line, the MuH1 and MuH4 lines did not provide higher fusion efficiencies, but gave increased opportunities to obtain hybridomas producing specific antibodies. Among a total of eight hybridomas, four derived from HuM1 and four derived from MuH4, seven secreted both IgG and IgM, and the remaining one derived from MuH1 secreted only IgG. In all eight hybridoma lines. IgG was specifically reactive to human IgG.
