Menstrual Cycles Continue into Advanced Old Age in the Common Chimpanzee(Pan troglodytes)1

Sera from eight different non-human primate species, in total 216 samples, were analysed for the presence of TT virus (TTV) sequences. A very high incidence of TTV infection was found in sera from both common chimpanzees and pygmy chimpanzees, 48·8% and 66·7%, respectively. Sequence analysis of PCR fragments from two pygmy chimpanzees and seven common chimpanzees resulted in a total of 14 different TTV sequences. Phylogenetic analysis, including human TTV of all known genotypes, revealed that: (i) TTV from pygmy chimpanzees are closely related to viruses from human genotypes 2 and 3; (ii) TTV sequences obtained from common chimpanzees cluster together with human TTV genotypes 5 and 6, the latter only at the protein level; (iii) TTV from the common chimpanzee subspecies Pan troglodytes verus and Pan troglodytes schweinfurthii cluster together, suggesting an ancient host–pathogen relationship before subspeciation 1·6 million years ago; and (iv) TTV of common and pygmy chimpanzees may have been acquired by these animals in different zoonotic events not longer than 2·5 million years ago.

Anxiety and fear of dentistry are some of the common topics among most children. The purpose of this study is to survey the effect of therapist gender on the anxiety of children. Due to considerable hypotheses and questions in this study, the t-dependent method is used to reach results. Zung questionnaire was used for the assessment of children's anxiety to 8 years old age, which was included 20 questions that considered a physical and mental condition of anxiety, which is based on the spectrum scales of not being, low, medium, and high. The statistical community consisted of 60 people obtained through a random selection of samples. The results arising from this study showed that children have more cooperation and calmness with female therapists, and their anxiety is less than the children who were treated by male therapists.
